-# Coding Standards
-
-These rules apply to every file in this repo , for humans and agents alike.
-
-## General rules
-
-1. Follow standard conventions.
-2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
-3. Boy scout rule. Leave the campground cleaner than you found it.
-4. Always find root cause. Always look for the root cause of a problem.
-
-## Design rules
-
-1. Keep configurable data at high levels.
-2. Prefer polymorphism to if/else or switch/case.
-3. Separate multi-threading code.
-4. Prevent over-configurability.
-5. Use dependency injection.
-6. Follow Law of Demeter. A class should know only its direct dependencies.
-
-## Understandability tips
-
-1. Be consistent. If you do something a certain way, do all similar things in the same way.
-2. Use explanatory variables.
-3. Encapsulate boundary conditions. Boundary conditions are hard to keep track of. Put the processing for them in one place.
-4. Prefer dedicated value objects to primitive types.
-5. Avoid logical dependency. Don't write methods which work correctly only depending on something else in the same class.
-6. Avoid negative conditionals.
-
-## Names rules
-
-1. Choose descriptive and unambiguous names.
-2. Make meaningful distinctions.
-3. Use pronounceable names.
-4. Use searchable names.
-5. Replace magic numbers with named constants.
-6. Avoid encodings. Don't append prefixes or type information.
-
-## Functions rules
-
-1. Small.
-2. Do one thing.
-3. Use descriptive names.
-4. Prefer fewer arguments.
-5. Have no side effects.
-6. Don't use flag arguments. Split the method into several independent methods that can be called from the client without the flag.
-
-## Comments rules
-
-1. No comments in the codebase. This covers Go, TypeScript/Vue, HTML templates and config files (YAML, TOML, `.env.example`, `.gitattributes`, …).
-2. Explain yourself in code instead: descriptive names, small functions, named constants, explanatory variables.
-3. The only exceptions are tool directives the code needs to work, such as `//go:build` and `//go:embed`.
-4. Don't comment out code; just remove it.
-5. Prose belongs in `docs/` and `README.md`, not in source files.
-
-## Source code structure
-
-1. Separate concepts vertically.
-2. Related code should appear vertically dense.
-3. Declare variables close to their usage.
-4. Dependent functions should be close.
-5. Similar functions should be close.
-6. Place functions in the downward direction (caller above callee).
-7. Keep lines short.
-8. Don't use horizontal alignment.
-9. Use white space to associate related things and disassociate weakly related ones.
-10. Don't break indentation.
-
-## Objects and data structures
-
-1. Hide internal structure.
-2. Prefer data structures when there's no behavior to attach.
-3. Avoid hybrid structures (half object, half data).
-4. Keep classes small.
-5. Each class should do one thing.
-6. Keep the number of instance variables small.
-7. Base classes should know nothing about their derivatives.
-8. Prefer many small functions over one function with a parameter that selects behavior.
-9. Prefer non-static methods to static methods.
-
-## Tests
-
-1. One assert per test.
-2. Readable.
-3. Fast.
-4. Independent.
-5. Repeatable.
-
-## Code smells to watch for
-
-1. **Rigidity** — the software is difficult to change; a small change causes a cascade of subsequent changes.
-2. **Fragility** — the software breaks in many places due to a single change.
-3. **Immobility** — you cannot reuse parts of the code in other projects because of the risk and effort involved.
-4. **Needless complexity**.
-5. **Needless repetition**.
-6. **Opacity** — the code is hard to understand.

 Data is stored in `./data/` by default. For a real server (systemd, HTTPS, backups), see **[docs/deployment.md](docs/deployment.md)**.
 
+### Run with Docker
+
+```sh
+cp docker.env.example docker.env    # fill in PUBLIC_URL, JWT_SECRET and SMTP_*
+docker compose pull
+docker compose up -d                # http://localhost:8080

+
+Upgrade with `docker compose pull && docker compose up -d`. The image is `git.floriansylvain.fr/fsylvain/renewcms`. Every release is a pre-release for now, so the default tag is the moving `beta`. Pin a version with `RENEWCMS_IMAGE`. Tags, building from source and publishing are in **[docs/docker.md](docs/docker.md)**.
+
+### Updates from the browser
+
+On Linux with systemd, install v2.6.0-beta or newer manually, then follow [the browser-update setup guide](docs/deployment.md#browser-updates). It covers finding the actual database directory, installing the helper, testing a restart and troubleshooting. Other platforms use manual upgrades.

+# API reference
+
+The full, searchable reference is the Integration page of the running app (`/integration`). It
+renders `web/src/data/apiCatalogue.ts`, which is the single source for this page. This file is for
+readers without the UI. Reading articles (pagination, `format`, body schemas) has its own page,
+[api/articles.md](api/articles.md), and API keys are covered in [api/api-keys.md](api/api-keys.md).
+
+## Base URL
+The origin that serves the app, for example `https://cms.example`. Every path starts with `/v1`,
+for example `https://cms.example/v1/article/`.
+
+## Authentication
+- Public routes need nothing: `GET /v1/article/`, `GET /v1/article/{id}`, `GET /v1/article/{id}/seo`
+  and `GET /v1/site/{key}/sitemap`. They return online articles, plus the drafts the caller's role may read
+  (see [Content permissions](#content-permissions)); any other draft answers 404 `Article not found`.
+- Everything else needs a signed-in browser session (the `jwt` cookie) or an API key:
+  `Authorization: Bearer rcms_...`. Create keys at `/integration/api-keys`. A key acts as its
+  creator, with that user's role, and shows in full once.
+- A key cannot call `POST /v1/auth/verify`, `DELETE /v1/auth/register`, `/v1/api-key/*` or
+  `/v1/system/*`. Those answer 403 "This action needs a real session." An invalid, unknown, expired
+  or revoked key answers 401, even on public routes. The site writes (`POST`, `PATCH` and `DELETE`
+  under `/v1/site`) and the author writes (`POST`, `PATCH` and `DELETE` under `/v1/author`, `POST /v1/author/me` included) are session only too.
+- Each key can make 120 requests per minute. Beyond that: 429 with a `Retry-After` header.
+- A session lasts 24 hours. `POST /v1/auth/logout` revokes it on the server, so a copied cookie
+  stops working at once; other sessions of the same user stay valid. A password reset ends every
+  session and revokes every key of that user.
+- A browser `POST`, `PUT`, `PATCH` or `DELETE` sent from another origin without an
+  `Authorization` header answers 403 "Cross-origin requests are not allowed." This blocks
+  cross-site request forgery with the cookie; scripts on other origins must send their key.
+
+## Routes a key can call (30)
+| Group | Routes |
+| --- | --- |
+| Articles | GET /v1/article/, GET /v1/article/{id}, GET /v1/article/{id}/seo, POST /v1/article/{id}/seo/check, POST /v1/article/, PATCH /v1/article/{id}, PATCH /v1/article/{id}/publish, PATCH /v1/article/{id}/unpublish, DELETE /v1/article/{id} |
+| Media | GET /v1/media/, GET /v1/media/{id}, POST /v1/media/, PATCH /v1/media/{id}, DELETE /v1/media/{id}, POST /v1/media/merge, GET /v1/media/{id}/usage, GET /v1/media/purge-settings (owner or admin), PATCH /v1/media/purge-settings (owner or admin), GET /v1/media/purge-preview (owner or admin), POST /v1/media/purge (owner or admin), GET /v1/media/{id}/variants (owner or admin, session only), POST /v1/media/{id}/variants (owner or admin, session only), POST /v1/media/{id}/variants/{name} (owner or admin, session only), DELETE /v1/media/{id}/variants/{name} (owner or admin, session only) |
+| Users and invites | GET /v1/user/ (`users.view`), PATCH /v1/user/me, POST /v1/user/invite (`users.invite`), DELETE /v1/user/invite/{id} (`users.invite`), POST /v1/user/invite/{id}/renew (`users.invite`), GET /v1/auth/me (with the linked `author`) |
+| Settings | GET /v1/settings |
+| Sites | GET /v1/site/, GET /v1/site/{key}/sitemap |
+| Authors | GET /v1/author/ |
+
+## Activity log
+The activity routes are session only: a key answers 403 "This action needs a real session." and a
+key never reads the audit trail. Events are append-only; there is no `POST`, `PUT`, `PATCH` or
+`DELETE` under `/v1/activity`.
+
+| Route | Who | Purpose |
+| --- | --- | --- |
+| `GET /v1/activity` | Any verified user | Filtered, paged events. A role with `activity.view` at all sees every event; a role at own is scoped to its own events, and `actor` set to someone else answers 403 `missing_permission`. |
+| `GET /v1/activity/summary` | Owner, admin | Counts for the range, the previous period, active people and seven-bucket series. |
+| `GET /v1/activity/export` | Owner, admin | The same filters as the list without `page` or `size`, as a `text/csv; charset=utf-8` attachment (`when,actor,action,target,outcome,source,ip`). Cells starting with `=`, `+`, `-` or `@` get a leading quote. |
+
+Query: `q`, `actor` (`user:ID`, `key:ID`, `system`), `category` (`articles`, `media`, `users`,
+`api_keys`, `auth`, `system`, `sites`, `authors`, `roles`), `outcome` (`all`, `success`, `failed`), `security` (`true`), `range`
+(`today`, `7d`, `30d`, `all`, `custom`; default `7d`), `from` and `to` (dates, with `custom`), `page` (from
+1) and `size` (25, 50 or 100). Any invalid value answers 400 with the body-mismatch message. Dates
+are UTC. The list answers `{ items, total, page, size }`, newest first (`created_at`, then `id`).
+
+`GET /v1/settings` also returns `activity_retention_days` (30, 90, 365 or 0 for forever, default
+90), `activity_retention_max_gb` (0 for no size limit), `activity_log_size_bytes`,
+`activity_last_cleanup_at` and `activity_last_cleanup_removed`. `PATCH /v1/settings` with
+`{"activity_retention_days": 30}`, `{"activity_retention_max_gb": 5}` or both is session only and
+needs `system.edit_retention` (403 `missing_permission`); any other value answers 400. The daily cleanup
+removes events past the age limit, then the oldest events until the log fits the size limit.
+Whichever limit is reached first wins.
+
+### What is recorded
+Every real action is recorded by its use case, once, after the change was made (outcome `success`)
+or after the use case refused it (outcome `failed`, with a plain `failure_reason`). Nothing is
+recorded for a read (no `GET`, no list, no public article read, no status poll), for a request that
+fails validation, or for a target that does not exist (404). A failed audit write is logged and
+never changes the response or the change itself.
+
+| Category | Actions |
+| --- | --- |
+| `articles` | `article.create`, `article.edit`, `article.publish`, `article.unpublish`, `article.delete` |
+| `media` | `media.upload`, `media.rename`, `media.delete`, `media.merge`, `media.purge`, `media.variant_create`, `media.variant_update`, `media.variant_delete`, `media.variant_enable`, `media.variant_disable`, `media.variant_purge`, `media.variant_generate_all`, `media.variant_purge_image`, `media.variant_purge_all`, `media.variant_purge_unused` |
+| `users` | `user.register`, `user.verify`, `user.update_profile`, `user.change_role`, `user.transfer_ownership` (flagged `security`), `invite.create`, `invite.cancel`, `invite.renew`, `invite.accept` |
+| `sites` | `site.create`, `site.edit`, `site.set_default`, `site.delete` |
+| `authors` | `author.create`, `author.edit`, `author.delete` |
+| `system` | `system.media_purge` (scheduled), `system.update_checked`, `system.update_downloaded`, `system.restart_requested`, `system.activity_cleanup`, `system.activity_retention_changed` |
+
+Target types: `article`, `site`, `author`, `image`, `image_variant` (id and name are the variant name), `user`, `invite`,
+`api_key` and `release` (id and name are the tag).
+Only the fields `title`, `online`, `body`, `site`, `name`, `base_url`, `default_robots`, `locale`, `default_social_image`, `slug`, `canonical_url`, `noindex`, `cover_image`, `social_image`, `excerpt`, `seo_title`, `seo_description`, `social_title`, `social_description`, `cover_image_alt`, `site_name`, `title_template`, `default_description`, `bio`, `website`, `social_links`, `avatar`, `user`, `authors`, `filename`, `display_name`, `width`, `height`, `fit`, `format` and `quality` appear in `changes` (a site key is never a change; moving an article records `site` with the site names; changing the credited authors records `authors` with the names in order; the `user` change of an author holds usernames, never an email), with the
+kinds `text` and `body`; a body edit carries a signed character count delta and never the text; the free-text SEO fields (`excerpt`, `seo_title`, `seo_description`, `social_title`, `social_description`, `cover_image_alt`) do the same under their own field name, while `slug`, `canonical_url`, `noindex`, `cover_image`, `social_image` (image file names) and the site fields `site_name`, `title_template`, `default_description` carry `before` and `after`. `seo_dismissed` is not an edit and records nothing. A
+change that leaves a value as it was (same body, same publish state, same file name, same display
+name) records nothing. Params: `media.merge` and `media.purge` and `system.media_purge` carry
+`merged` and `articles_updated`, plus `failed_groups` when a group failed (still outcome `success`);
+`media.variant_generate_all` carries `generated`, `failed` and `causes` (a list of `too_large`,
+`unsupported_format` or `failed`) and is `failed` only when nothing was generated and something failed;
+`media.variant_purge_image` carries `purged_files` and `purged_bytes`; both have an `image` target
+and are recorded only when files were generated or removed;
+`media.variant_purge_all` and `media.variant_purge_unused` (no target) carry `purged_files` and
+`purged_bytes`, the latter also `older_than_days`; a partial purge adds `failed_files` and stays
+`success`, and a purge that removed nothing while some files failed is `failed`; nothing is recorded
+when no file was removed or failed;
+`system.update_checked` carries `update_available`; `system.restart_requested` carries `kind` and,
+for an update, `tag` (it has no target). `system.update_downloaded` is recorded when the job reaches
+`ready` or `failed`, with the origin captured at request time; a refusal at the start is recorded
+immediately. A failed registration or invite acceptance has an `anonymous` actor named by the
+attempted username.
+
+`failure_reason` is one fixed sentence per domain error, matched with `errors.Is`, at most 255
+characters, for example "The title must be between 3 and 200 characters.", "That file name is not
+valid.", "The merge request is not valid.", "A purge is already running.", "Registration is closed
+on this site.", "That invitation has expired.", "The release feed could not be reached." or "The
+update could not be downloaded.". Any other error becomes "Something went wrong on our side. Please
+try again."; the text of the error never reaches the event, the API or the CSV. Passwords, hashes,
+codes, article bodies, file bytes, storage paths and asset urls are never recorded.
+
+Article routes accept `?format=markdown|html|json` (default `markdown`). `GET /v1/media/` accepts
+`q`, `hash`, `filter` (`all`, `unused` or `duplicates`), `sort` (`newest`, `oldest`, `name`,
+`largest` or `total_size`, the original plus its generated variants), `variants` (`with` or
+`without` generated variant files), `page` (a whole number from 1, default 1) and `size` (5, 25, 50
+or 100, default 25). The body is `{ "items": [...], "total", "page", "size", "counts" }`: `total` is
+the number of images matching `q`, `hash`, `filter` and `variants` before paging, `page` and `size`
+echo the values applied, and `counts` (`all`, `unused`, `duplicates`) stays library-wide, ignoring
+every filter and the paging. Ordering is applied to the whole matching list before slicing, with the
+image id as the final tie-break, so pages never overlap or skip. A page past the last answers 200
+with `items: []` and the real `total`. Any invalid `page`, `size`, `filter`, `sort`, `variants` or
+`hash` is 400 "The media query is invalid.". Every item carries `variant_count` and `variant_size`
+(the index rows of the image and their bytes, 0 when none).
+
+`GET /v1/media/{id}` reads one image with the same auth as the list (a verified session or an API key; 403 for an
+unverified account, 401 without credentials) and writes nothing, so it records no activity event. It answers 200 with
+the object of one `items` element of the list, a missing image is 404 "Image not found" and a malformed id is 400 with
+the id-format message.
+
+Breaking change: `next_cursor` is gone and no `X-Total-Count` header is sent. `cursor` and `limit`
+are no longer parameters; they are ignored, never an error, and have no effect on paging.
+
+## Sites
+Every article belongs to exactly one site, and exactly one site is the default. A site is `{ id,
+name, key, base_url, default_social_image_id, default_robots, locale, is_default, article_count }`:
+`name` is 1 to 100 characters, `key` is 2 to 32 characters of lowercase letters, digits and single
+dashes (`^[a-z0-9]+(-[a-z0-9]+)*$`) and never changes, `base_url` is `https` (or `http` for
+`localhost`, `127.0.0.1` and `[::1]`) with no path, query or user info (a trailing slash is
+stripped, uniqueness is not enforced), `default_robots` is `index` (default) or `noindex`, `locale`
+is `null` or a tag such as `en` or `fr-CA` (an empty string means none) and `default_social_image_id`
+is `null` or the id of an image. Read access needs a verified session or an API key; every write is
+session only and need `settings.manage_sites` (`settings.delete_site` for DELETE): 403 `missing_permission`, or "This action needs a real
+session." with a key. The role is checked before the body.
+
+| Route | Purpose |
+| --- | --- |
+| `GET /v1/site/` | The sites, default first and then by name, each with `article_count`. Query `q` (up to 200 characters, matched in `name`, `key` or `base_url`, ignoring case and accents, `%` and `_` literal), `page` (a whole number from 1) and `size` (5, 25, 50 or 100). Without `page` and `size` every matching site is returned; with only `page`, `size` is 25; with only `size`, `page` is 1. The body stays a JSON array (`[]` when nothing matches, never `null`) and `X-Total-Count` holds the number of matching sites before paging. A page past the end is `200 []` with the total. An invalid `page`, `size` or `q` is 400 with the body-mismatch message and no `X-Total-Count`. |
+| `POST /v1/site/` | Create. 201 with the site. `is_default: true` makes it the default. `site_name`, `title_template` and `default_description` are optional and validated like on `PATCH`. |
+| `PATCH /v1/site/{id}` | Edit `name`, `base_url`, `default_robots`, `locale`, `default_social_image_id`, `site_name`, `title_template`, `default_description`. Absent fields are untouched. `key` may only be repeated unchanged; `is_default` is refused. |
+| `PATCH /v1/site/{id}/default` | Make the site the default, atomically. Setting the current default is a no-op. |
+| `DELETE /v1/site/{id}?reassign_to={id}` | 204. A site with articles needs `reassign_to`; the articles move and the site is deleted in one transaction. `reassign_to` is ignored when the site has no article. |
+
+Errors are plain text whose body is exactly the token: 409 `site_key_taken`, 409 `site_has_articles`,
+403 `default_site` (checked before the articles), 400 `key_immutable`, 400 `invalid_site_url`, 400
+`invalid_locale`, 400 `invalid_title_template`, 400 `image_not_found`, 400 `use_set_default`, 400 `invalid_reassign` (missing
+number, the site itself or not a whole number) and 404 `site_not_found`. Refused writes except `site_not_found` and `image_not_found` are recorded as failed events. A body that cannot be
+decoded is 400 with the body-mismatch message, a malformed id is 400 with the uint32 message, and a
+field that fails validation (`name`, `key` format, `default_robots`, `site_name` over 100 characters, `title_template` over 200, `default_description` over 320) is 400 with the validator text.
+
+A site also carries `site_name` (at most 100 characters, `""` by default), `title_template` (at most 200 characters, `%title% | %site%` by default; it must contain `%title%`, case sensitive, otherwise 400 `invalid_title_template`, an empty template included) and `default_description` (at most 320 characters, `""` by default). They appear on every site response, `POST` accepts them and `PATCH` edits them like the other site fields. Existing sites get the defaults when the server starts after the upgrade.
+
+Articles carry `site_id`. A new article starts on the default site. `GET /v1/article/?site=<key>`
+keeps only the articles of that site and composes with `status`, `q`, `sort`, `size` and `page`;
+`counts` stay global, an unknown key answers 200 with no item and an empty `site=` is 400 with the
+body-mismatch message. `PATCH /v1/article/{id}` takes `body`, `site_id`, `author_ids` and the SEO
+fields below, and nothing else, such as `title`: absent fields are untouched, an empty object, an object without
+those fields, a `null` value (except on `cover_image_id` and `social_image_id`) or a malformed value is 400 with the body-mismatch message, `site_id: 0` is
+400 with the validator text and an unknown site is 404 `site_not_found`. Moving an article never
+changes `is_online`. `{"body": ""}` still sets an empty body, but `{}` and `{"body": null}` no longer do: they are 400.
+
+### Resolved SEO, check, list status and sitemap
+
+RenewCMS renders no page and injects no meta tag: it returns the data a frontend needs.
+
+| Route | Who | Purpose |
+| --- | --- | --- |
+| `GET /v1/article/{id}/seo` | public for online articles; a verified session or API key also reads the drafts its role may read | The resolved object `{ title, description, canonical_url, robots, og, twitter, image, authors, published_at, modified_at, fallbacks, json_ld }`. It never carries the body, the id or `seo_dismissed`, ignores `format`, and writes nothing. An offline article for any other caller, and a missing one, is 404 `Article not found`. |
+| `POST /v1/article/{id}/seo/check` | verified session or API key (401 without credentials, 403 unverified) | Evaluates the article without saving. The body is `{}` or any of the twelve SEO fields of `PATCH` plus `body`; each replaces the saved value for this check only. `site_id`, `author_ids`, unknown fields and `null` (except on `cover_image_id` and `social_image_id`) are 400 with the body-mismatch message. The other validation is the one of `PATCH` (`invalid_slug`, `invalid_url` as 422, `image_not_found`, validator text). Answers `{ status, suggestions, slug }` where `suggestions` is `[{ code, field, params }]` and `slug` is `{ available, suggestion }`. A taken slug is a 200 with `available: false` and the first free `<slug>-N` in `suggestion`, never a 409. |
+| `GET /v1/site/{key}/sitemap` | public | A JSON array `[{ url, modified_at, noindex }]` of the online articles of the site with that key, by id ascending. `url` is `base_url/slug` (never the canonical override). `page` (default 1) and `size` (25, 50, 100 or 500, default 100); an invalid value is 400 with the body-mismatch message. The total is in the `X-Total-Count` header. An unknown key, an id included, is 404 `site_not_found`. |
+
+`GET /v1/article/` also takes `seo=ready|suggestions|hidden` (any other value, an empty one included, is 400 with the body-mismatch message, after the `format` check). It is applied before paging and composes with `q`, `status`, `site`, `sort`, `page` and `size`; `total` follows it and `counts` ignore it. Every item carries `seo_status` (`ready`, `suggestions` or `hidden`) and `seo_suggestions` (the number of suggestions that are not dismissed). The filter is evaluated in memory over every matching article, so its cost grows with the number of articles on the site; without it only the returned page is assessed.
+
+`X-Total-Count` is added to `Access-Control-Expose-Headers` next to `Link`, so a browser on an allowed origin can read it.
+
+### Article SEO fields
+
+An article carries twelve search and sharing fields, all edited through `PATCH /v1/article/{id}` and returned by
+every single-article read (`GET /v1/article/{id}`, `POST`, `PATCH`, `publish`, `unpublish`):
+`slug`, `excerpt`, `seo_title`, `seo_description`, `cover_image_id`, `cover_image_alt`, `social_title`,
+`social_description`, `social_image_id`, `canonical_url`, `noindex` and `seo_dismissed`. Text fields are `""`
+when empty, the two image ids are `null` when unset, `noindex` is `false` and `seo_dismissed` is `[]` by
+default. Each item of `GET /v1/article/` carries `excerpt` and `slug` and none of the other ten.
+The limits are counted in characters: `excerpt` 300, `seo_title` 120, `seo_description` 320,
+`cover_image_alt` 200, `social_title` 120, `social_description` 320, `canonical_url` 2048; going over is
+400 with the validator text. `cover_image_id` and `social_image_id` accept `null` (and only those two do);
+`0` is 400 with the validator text and an unknown image is 400 `image_not_found`. `canonical_url` is `""` or an absolute
+`https` URL with a host, otherwise 422 `invalid_url`. `seo_dismissed` is a list of the codes `title_long`,
+`title_empty`, `desc_short`, `desc_long`, `cover_alt`, `cover_none`, `slug_long`, `no_au`, `no_h`, `body_alt`
+and `short`: an unknown code is 400 with the validator text and duplicates are collapsed with the order
+kept. `noindex` is only a flag, it does not take the article offline.
+
+The `slug` matches `^[a-z0-9]+(-[a-z0-9]+)*$` with 1 to 100 characters (400 `invalid_slug`) and is unique per
+site, never globally. It is generated from the title when the article is created: lowercase, accents folded,
+every run of other characters becomes one dash, dashes trimmed, cut to 100 characters, and `article` when no
+letter or digit is left; a slug already used on the site gets `-2`, `-3`... silently. The same rule
+backfills the existing articles when the server starts after the upgrade (in id order within each site, so
+the oldest article keeps the plain slug). Sending `slug: ""` regenerates the slug from the title. A slug
+used by another article on the target site (the new site when `site_id` is sent too, and a move re-checks
+the current slug) is 409 with the plain-text body `slug_taken`; the response then carries the header
+`X-Slug-Suggestion` holding the first free `<slug>-N` from 2 on that site, fitting 100 characters. The header
+is set on this 409 only, never on another response. A regeneration that collides is refused the same way, never suffixed
+silently. Saving an article with its own slug is not a collision. Publishing never changes a slug, a deleted article
+frees its slug.
+
+New error tokens are plain text from the handler: 409 `slug_taken`, 400 `invalid_slug`, 422 `invalid_url`, 400
+`image_not_found` and 400 `invalid_title_template` (sites). Edits that change a SEO field are recorded as
+`article.edit` events (`slug`, `canonical_url`, `noindex`, `cover_image`, `social_image` with before and after;
+the free-text fields as a size delta only); a refused slug is recorded as failed.
+
+A site's `default_social_image_id` counts as a use of that image: it raises `used_in` and keeps the
+image out of the `unused` filter. Deleting the image sets the field to `null` and succeeds. `POST /v1/media/merge` and `POST
+/v1/media/purge` repoint the sites of the merged copies to the kept image and report it as
+`sites_updated` next to `articles_updated`.
+
+An article's `cover_image_id` and `social_image_id` count the same way. `used_in` counts every article that uses the
+image in its body, as cover or as social image once, plus the authors using it as an avatar and the sites using it as default
+social image. Deleting an image never fails because of its uses: the covers and social images pointing at it are set to `null`
+(the `cover_image_alt` and the bodies are untouched), and a failed delete leaves every reference in place. A merge or a purge repoints
+the covers and social images of the copies to the kept image, and an article rewritten in its body and its cover counts once in
+`articles_updated`.
+
+`GET /v1/media/{id}/usage` stays an array. Every item keeps the keys it had and gains `type` (`article`,
+`author` or `site`) and `fields`. An article item is `{ "type": "article", "id", "title", "published", "fields" }` with
+`fields` from `body`, `cover` and `social` (one item per article, in that order); an author item is
+`{ "type": "author", "id", "title": <name>, "fields": ["avatar"] }` and a site item is `{ "type": "site", "id", "title": <name>,
+"fields": ["default_social_image"] }`; author and site items have no `published` key. The array is `[]` for an unused image.
+
+## Authors
+
+An author is a public byline, with or without an account. It is `{ id, name, slug, bio, avatar_id,
+website, social_links, user_id, is_linked, article_count }`, plus `user_email` for owners and admins
+only (absent for every other caller). `name` is 1 to 100 characters after trimming, `slug` matches
+`^[a-z0-9]+(-[a-z0-9]+)*$` with 1 to 100 characters and is unique (generated from the name when
+omitted: accents folded, punctuation runs become one dash, `author` when nothing is left), `bio` has
+at most 280 characters (counted in runes), `avatar_id` is `null` or an image id, `website` is `null`
+or an `https` URL with a host (an empty string means none, at most 2048 characters),
+`social_links` holds at most 5 `{ "type", "url" }` with `type` one of `x`, `linkedin`, `github`,
+`mastodon`, `custom` and an `https` URL. `user_id` is the unique link to a user. Zero authors on an
+article is allowed and never blocks publishing.
+
+| Route | Who | Purpose |
+| --- | --- | --- |
+| `GET /v1/author/` | verified session or API key | The authors newest first. Query `q` (name or slug, accent and case insensitive), `page` (default 1), `size` (5, 25, 50 or 100, default 25). Body `{ items, total, page, size }`, with `total` repeated in the `X-Total-Count` header on every 200; a bad query is 400 with the body-mismatch message and no header. |
+| `POST /v1/author/` | owner or admin, session only | Create. 201 with the author. `user_id` links an account that has no author. |
+| `POST /v1/author/me` | any verified session | Create the caller's own author from the display name (or the username). A taken slug gets `-2`, `-3`... silently. 201 with the author plus `slug_adjusted`: `true` when the stored slug differs from the plain slug of the name (a collision suffix was added), `false` otherwise. No other author response carries this field. |
+| `PATCH /v1/author/{id}` | owner or admin on any author; any verified session on the author linked to it; session only | Edit `name`, `slug`, `bio`, `avatar_id`, `website`, `social_links`, `user_id`. Absent fields are untouched, `avatar_id`, `website` and `user_id` accept `null`, `social_links` is replaced as a whole. `user_id` links or unlinks the account and is owner or admin only. |
+| `DELETE /v1/author/{id}?reassign_to={id\|none}` | owner or admin, session only | 204. An author credited on articles needs `reassign_to`: an author id (that author takes the deleted one's position and is never duplicated on an article) or `none` (the credit is removed). The move and the delete are one transaction. `reassign_to` is ignored when the author has no article. The linked account is untouched. |
+
+The role checks use the existing bodies: 403 `missing_permission` for `POST /` and
+`DELETE`, 403 `author_rights` for a `PATCH` by a role that holds `authors.edit` at own on an author
+that is not its own (or that sends `user_id`), and 403 "This action needs a real session." for a key.
+Errors are plain text whose body is exactly the token: 404 `author_not_found`, 404 `user_not_found`,
+409 `author_slug_taken`, 409 `author_has_articles`, 409 `user_already_linked`, 409
+`author_already_linked`, 400 `invalid_slug`, 400 `invalid_reassign` (own id, not a whole number,
+negative or empty), 400 `image_not_found`, 422 `bio_too_long`, 422 `invalid_url` and 422
+`too_many_links`. A body that cannot be decoded, an empty `PATCH` or one that nulls a required field
+is 400 with the body-mismatch message, a malformed id is 400 with the uint32 message and other
+validation failures (`name`, link `type`) are 400 with the validator text. Writes refused for a
+reason other than a missing target or an invalid value are recorded as failed events.
+
+Articles carry `authors`, the ordered credits (the first is the primary byline), each with only `id`,
+`name`, `slug`, `bio`, `avatar_id`, `website` and `social_links`; it is `[]` when there is none and it
+is visible on online articles to anonymous readers. `PATCH /v1/article/{id}` also takes
+`author_ids`, the whole ordered list: it replaces the credits, `[]` empties them, an unknown id is 404
+`author_not_found`, a duplicate, `null` or a malformed list is 400 with the body-mismatch message and
+`0` is 400 with the validator text. Absent means unchanged. A new article is credited to the
+creator's linked author when there is one. `GET /v1/auth/me` returns the existing user fields plus
+`author`: the caller's linked author (`id`, `name`, `slug`, `bio`, `avatar_id`, `website`,
+`social_links`, `article_count`) or `null`.
+
+An author's `avatar_id` counts as a use of that image like a site's social image: it raises `used_in`
+and keeps the image out of the `unused` filter, and `GET /v1/media/{id}/usage` lists the author with the field `avatar`.
+Deleting the image sets `avatar_id` to `null`. `POST /v1/media/merge` and `POST /v1/media/purge`
+repoint the avatars of the merged copies and report it as `authors_updated`.
+
+## Image variants
+Owners and admins manage named variants of the stored images. These routes are session only (no API
+key) and sit behind the verified-user check; a role without the needed permission gets 403 `missing_permission`. Behaviour, caching and the public `?v=<name>` contract are in [image-variants.md](image-variants.md).
+
+| Route | Purpose |
+| --- | --- |
+| `GET /v1/image-variants` | `{ "items": [...] }`, ordered by name. |
+| `POST /v1/image-variants` | Create. 201 with the variant. 409 when the name exists. |
+| `PUT /v1/image-variants/{name}` | Replace the definition (the name in the body is ignored). 200 with the variant and `purged_files`. |
+| `PATCH /v1/image-variants/{name}` | `{ "enabled": true }` or `{ "enabled": false }`. Keeps the generated files. |
+| `DELETE /v1/image-variants/{name}` | 204. Removes the definition and its generated files. |
+| `POST /v1/image-variants/{name}/purge` | `{ "purged_files", "purged_bytes" }`. Keeps the definition. |
+| `GET /v1/image-variants/cache` | Cache statistics, see below. |
+| `POST /v1/image-variants/cache/purge` | Purge generated files by scope, see below. |
+
+A variant is `{ name, width, height, fit, format, quality, generate_on_upload, enabled,
+generated_files, cache_size, created_at, updated_at }`. `width` and `height` are 1 to 8000 or `null`
+(at least one is required), `fit` is `cover`, `contain` or `inside` (default `cover`), `format` is
+`original`, `jpeg`, `png` or `webp` (default `original`), `quality` is 1 to 100 (default 82, `null`
+for `png`), `generate_on_upload` defaults to `false`, `enabled` to `true`, and `cache_size` is in
+bytes. A `PUT` that omits `generate_on_upload` or `enabled` keeps the stored value.
+
+Errors are plain text: 400 for a body that is not valid JSON, 404 "Variant not found", 409 "A variant
+named “thumb” already exists. Choose another name." and 422 with one sentence for the first invalid
+field (name, width and height, fit, format, quality).
+
+### Cache statistics and purge by scope
+
+`GET /v1/image-variants/cache` answers `{ generated_files, disk_used, variants_defined,
+variants_enabled, variants_disabled, rejected_requests, rejected_window_days, unused: { files, bytes,
+days }, by_variant: [{ name, enabled, files, bytes }], top_images: [{ id, filename, url, files, bytes }] }`.
+`by_variant` lists every defined variant by bytes descending then name; `top_images` lists the ten
+images using the most variant bytes (ties by id, images that no longer exist are skipped). `unused`
+counts the files of enabled variants whose reference time (the last public request, or the creation
+time when never requested) is older than 30 days. `rejected_requests` counts the public requests
+refused with 400 over today and the six previous UTC days. Pending request tracking is flushed before
+the read. Arrays are never `null`.
+
+`POST /v1/image-variants/cache/purge` takes `{ "scope": "all" | "unused" | "variant" | "image",
+"variant": "<name>", "image_id": <id> }` (`variant` for the scope `variant`, `image_id` for `image`; a
+target given for another scope is ignored) and answers `{ scope, purged_files, purged_bytes,
+failed_files }`. A purge that fails on some files still answers 200 with `failed_files` above 0; the
+failed rows are kept so the same request can be sent again. Errors are plain text: 400 for a body that
+is not valid JSON, 422 "Scope must be all, unused, variant or image." or "A variant name or an image
+id is required for this scope.", 404 "Variant not found" or "Image not found", 500 when the rows
+cannot be listed.
+
+### Variants of one image
+Owners and admins only, session only: a request with an API key is 401. All ids are image ids.
+
+| Route | Purpose |
+| --- | --- |
+| `GET /v1/media/{id}/variants` | `{ "unsupported": null, "items": [...] }` for the enabled variants in name order. `unsupported` is `"svg"` (with `items: []`) for an SVG. |
+| `POST /v1/media/{id}/variants` | Generates every enabled variant that is missing. `{ "generated", "failed", "failures": [{ "name", "cause" }], "items": [...] }`, 200 even when some fail. |
+| `POST /v1/media/{id}/variants/{name}` | Generates one enabled variant. 200 with the item. |
+| `DELETE /v1/media/{id}/variants/{name}` | Removes the generated file. `{ "purged_files", "purged_bytes" }`, also for a disabled variant. |
+
+An item is `{ name, width, height, fit, format, output_width, output_height, output_format,
+generated, size, url }`: `width` and `height` are the settings (`null` when auto), `output_*` the
+size and format the file has or will have (never above the source), `generated` is true only when
+the file exists with the variant's current settings, `size` is its bytes or `null`, and `url` is
+`/static/uploadedImages/<stored name>?v=<name>`. A `cause` is `too_large`, `unsupported_format` or
+`failed`. A file generated here is the same file the public url serves, and the other way round.
+Uploads generate the variants flagged `generate_on_upload` (enabled ones, raster sources only)
+before answering; a failure there is logged and never fails the upload.
+
+Errors are plain text: 400 for a malformed id, 404 "Image not found" or "Variant not found" (also for a
+disabled variant on `POST`), 413 "The source image is too large to generate this variant.", 415 "The
+source image can't be read, so this variant can't be generated.", 422 "Variants aren't generated for
+this format." and 500 "Internal server error".
+
+## Roles
+
+Routes under `/v1/role`, behind the verified chain. Reads accept a key; every write is session only (a key answers
+403 "This action needs a real session."). The permission is checked before the id, the body and any lookup.
+
+| Route | Permission | Purpose |
+| --- | --- | --- |
+| `GET /v1/role` | `roles.view` | Every role by id, built-ins first. |
+| `GET /v1/role/{id}` | `roles.view` | One role. |
+| `POST /v1/role` | `roles.manage` | Create a role (201). `built_in` and `locked` in the body are ignored. |
+| `PUT /v1/role/{id}` | `roles.manage` | Replace name, description and grants. `version` is required and must match. |
+| `DELETE /v1/role/{id}` | `roles.manage` | Delete a role with no members (204). |
+| `POST /v1/role/{id}/reassign` | `roles.manage` | Move every member to `{"target_role_id": N}`; answers `{"moved": n}`. |
+| `POST /v1/role/{id}/reset` | `roles.manage` and `roles.edit_owner_only` | Restore a built-in role to its seeded grants and description; body `{"version": N}`. |
+
+A role is `{ id, name, description, built_in, locked, version, grants, members, updated_at, updated_by }`.
+`grants` is the normalised effective list: catalogue order, unknown keys and owner-only keys on an unlocked role
+dropped, duplicates resolved to the most restrictive scope, and a per-type entry (`content.update:events`, scope
+`none` included) right after its wildcard. A response is always valid as the `grants` of a `PUT`. `members` counts
+the users holding the role plus the open invites (pending or expired, never accepted ones) for it, counted in two
+statements whatever the number of roles. A user whose `role_id` is 0 or names no role counts for nobody.
+`updated_at` (RFC 3339, UTC) and `updated_by` (`{ id, name }`, the display name else the username) are `null` for a role
+never edited since seeding, and `updated_by` is also `null` once the saving user is deleted.
+
+Refusals are plain text, one snake_case code per body:
+
+| Status | Body | When |
+| --- | --- | --- |
+| 400 | `unknown_permission`, `invalid_scope`, `owner_only_permission`, `duplicate_permission`, `unknown_content_type` | A grant is not valid (`unknown_content_type` for a `content.*:{type}` key that is neither `article` nor a content type). |
+| 400 | `invalid_role_name`, `built_in_name`, `not_built_in`, `invalid_reassign` | Blank name after trim; renaming a built-in role; resetting a custom role; a bad reassign target (self, the Owner role, unknown). |
+| 403 | `role_locked` | Editing, deleting or moving from the Owner role. |
+| 403 | `missing_permission` | The usual gate, plus `X-Missing-Permission: roles.edit_owner_only` when a built-in role is edited or reset without that permission. |
+| 403 | `own_role` | Editing, deleting or moving members out of the caller's own role. |
+| 403 | `escalation` | The caller would grant, or touch a role holding, more than they hold. `X-Escalation-Key` names the first offending key, such as `content.publish` or `content.publish:events`. |
+| 404 | `role_not_found` | Unknown role id. |
+| 409 | `role_name_taken`, `role_conflict`, `role_has_members`, `role_built_in` | Name already used (case-insensitive); stale `version`; the role still has members (users or open invites); deleting or moving members out of a built-in role. |
+
+Names are trimmed and unique case-insensitively. The order of checks on a write is: permission, id, body, role lookup,
+locked, built-in rules, own role, existing role covered by the caller, version, grant validation, new grants covered
+by the caller, name taken, write. Only the Owner holds `roles.edit_owner_only`, so only the Owner edits the Admin and
+Writer roles; owner-only keys are refused on every role a client can write. A save with nothing changed answers 200
+at the same version and records nothing. Members see an edit on their next request, and so do the keys they created.
+
+Activity: `role.create`, `role.edit`, `role.delete` and `role.reassign` in the `roles` category, target
+`{ type: "role", id, name }`. `role.edit` carries `name` and `description` changes and the params `added`, `removed`,
+`changed` (`{ key, from, to }`) and `members`; `role.reassign` carries `from`, `to` and `moved` (users and open invites together) and is recorded only when
+`moved` is above 0. A refusal records nothing.
+
+`GET /v1/auth/me` lists per-type entries in `access.permissions` (scope `none` included), right after their wildcard.
+Deleting a content type removes its per-type rows from every role (the affected roles' `version` goes up by one), and
+creating one with the key of a deleted type clears any stale row for that key.
+
+## Users, invites and ownership
+
+A user has exactly one stored role, `role_id`, and nothing else: there is no `role` string any more (the
+`users.role` column of older databases stays in place, unused). `RoleRef` is the one role summary shape,
+`{ id, name, built_in, locked }`. It appears as `access.role` in `GET /v1/auth/me`, as `role` on user and invite items
+(`null` for a user whose role cannot be resolved) and in the responses below. `PublicUser` is exactly `id`, `username`,
+`email`, `is_verified`, `created_at`, `updated_at` and `display_name` in every response that includes a user (login,
+verify, register, invite accept, `GET /v1/auth/me`); `GET /v1/auth/me` adds `author` and `access`.
+
+`role_assigned_by` is `{ id, name }` or `null`: who last set the user's role. It is stored as the nullable column
+`role_assigned_by_id` on the user (no foreign key, no backfill, existing rows are `NULL`) and the name is never stored: it
+is read from the current record of that user at read time (`display_name` when set, else `username`), so a rename shows
+at once. When that record is gone the whole object is `null`. It is set by `PUT /v1/user/{id}/role` to the caller (a
+request with the user's current role writes nothing), by invite accept to the inviter (`NULL` when the inviter record is
+missing), and by the ownership transfer: the new Owner is assigned by the former Owner, whose own value becomes `NULL`.
+First-user registration and `POST /v1/role/{id}/reassign` leave it alone. The key is always present on accepted-user
+items of `GET /v1/user` (gate `users.view`, unchanged; assigners are resolved from the users already loaded) and on
+`access` of `GET /v1/auth/me` (own data, one extra lookup at most). Invite items never carry it, and `PublicUser` and the
+login, verify, register and invite-accept bodies do not change.
+
+| Route | Permission | Session only | Purpose |
+| --- | --- | --- | --- |
+| `GET /v1/user` | `users.view` | no | Users and open invites, newest first. A user is `{ id, kind: "user", username, display_name, email, role, role_assigned_by, status: "accepted", created_at }`; an invite is `{ id, kind: "invite", email, role, status, created_at }`. The roles are read with one `List` call. |
+| `PUT /v1/user/{id}/role` | `users.change_role` | yes | Body `{"role_id": N}` (required). Answers 200 with the user item, whose `role_assigned_by` is the caller. |
+| `POST /v1/user/invite` | `users.invite` | no | Body `{"email", "role_id"}`; `role_id` is optional and 0 or absent means the Writer role. Answers 201 `{ id, kind: "invite", email, status, role, created_at, expires_at }`. |
+| `POST /v1/user/invite/{id}/renew` | `users.invite` | no | Renews an expired or pending invite; it keeps its role and the response carries it. |
+| `DELETE /v1/user/invite/{id}` | `users.invite` | no | Cancels an invite (204). No coverage is needed: cancelling removes power. |
+| `POST /v1/site/transfer-ownership` | `system.transfer_ownership` | yes | Body `{"user_id", "confirm_email"}` (both required). Answers 200 `{ "owner": { id, name }, "former_owner": { id, name, role } }`. |
+
+The no-escalation rule applies to people as it does to roles: the caller must cover (`GrantSet.Covers`) the target's
+current role and the new role on a role change, the role of an invite on create and renew. An API key may create and
+renew invites, and the check then uses the live role of the key's creator. Nobody can give, take away or invite to the
+Owner role: `PUT /v1/user/{id}/role` to or from it, and an invite for it, are 403 `role_locked`; only the transfer moves
+the Owner role. Changing the role of your own account is 403 `own_role`. Giving the role a user already holds answers
+200 and writes and records nothing. A role change keeps `token_version`, sessions and keys: the next request is decided
+by the new grants. An unverified user may be given a role.
+
+The order of checks on `PUT /v1/user/{id}/role` is: session, permission, id, body, target user, target holds a locked
+role, `role_id` lookup, new role locked, own account, current role covered, new role covered, same role (no-op), write.
+On `POST /v1/user/invite`: permission, rate limiter, body, inviter, role (default Writer), role locked, role covered,
+email already has an account, pending invite, create, mail. On `POST /v1/user/invite/{id}/renew`: invite lookup (404),
+already accepted (409), invite role covered, renew, mail. On `POST /v1/site/transfer-ownership`: session, permission,
+body, target, `confirm_email`, write. Every refusal writes nothing, not even the deletion of an expired invite.
+
+| Status | Body | When |
+| --- | --- | --- |
+| 409 | the human message | `POST /v1/user/invite` only. "This address already has an account." carries `X-Error-Code: email_has_account`; "There's already a pending invite for this address." carries `X-Error-Code: invite_pending`. |
+| 400 | `invalid_role` | `role_id` names no role (user change or invite), or the invite's role no longer exists on renew. |
+| 400 | `invalid_transfer` | The transfer target is unknown, yourself, unverified, or not a user (an invite id is never valid). |
+| 400 | `confirmation_mismatch` | `confirm_email` differs from the target's email (exact, case-sensitive match). |
+| 403 | `role_locked` | The target holds the Owner role, or the role to give is the Owner role. |
+| 403 | `own_role` | The target of a role change is the caller's own account. |
+| 403 | `escalation` | A role to cover is above the caller's grants; `X-Escalation-Key` names the first offending key. |
+| 403 | `missing_permission` | The gate, with `X-Missing-Permission`. A key on a session-only route answers 403 "This action needs a real session." first. |
+| 404 | `user_not_found` | Unknown user id on `PUT /v1/user/{id}/role`. |
+| 409 | `user_role_changed` | The target's role changed between read and write (a compare-and-swap on the role that was read), or the caller no longer holds the Owner role on a transfer. |
+
+Transferring ownership moves the Owner role to the target and gives the former owner the built-in Admin role in one
+transaction; both keep `token_version`, cookies and API keys, so the former owner's next request is decided by the
+Admin grants and the new owner's by the Owner grants. Exactly one verified user holds the Owner role afterwards, also
+under two simultaneous transfers (one answers 200, the other 409).
+
+Accepting an invite (`POST /v1/auth/invite/accept`) creates the user with the role the invite names, read at accept
+time; an invite whose `role_id` is 0 or names a deleted role answers the usual invalid-invite 404 and creates nothing.
+Registration creates the first user with the built-in Owner role; when the Owner role is not seeded it answers 500.
+A user whose `role_id` is 0 or names no role is denied on every gated route (403 `missing_permission`) and gets 500 on
+`GET /v1/auth/me`; it is never promoted.
+
+Activity: `user.change_role` (category `users`, target the user, `changes` holds `{ field: "role", kind: "text", before,
+after }` with the role names, params `from` and `to` hold the role ids) and `user.transfer_ownership` (category `users`,
+`security: true`, target the new owner, params `from` and `to` hold the two user ids). `invite.create` and
+`invite.accept` carry the params `role_id` and `role` (the role name); `invite.renew` is unchanged. A refusal and a
+no-op record nothing; a storage failure at the write records the same event with outcome `failed`.
+
+## Content permissions
+
+Articles and the entries of custom content types are checked against the `content.*` permissions of the
+caller's role, which is read on every request (a key follows its creator's role).
+
+| Route | Permission | Scope check after the lookup |
+| --- | --- | --- |
+| `GET /v1/article/`, `GET /v1/article/{id}`, `GET /v1/article/{id}/seo` | public, `content.read` widens what drafts show | online articles, plus drafts when `content.read` is `all`, or the caller's own drafts when it is `own` |
+| `POST /v1/article/{id}/seo/check` | `content.read` | the article must be visible, else 404 |
+| `POST /v1/article/` | `content.create` | none; `created_by` is the caller and the article is always a draft |
+| `PATCH /v1/article/{id}` | `content.update` | `own` needs `created_by` to be the caller |
+| `DELETE /v1/article/{id}` | `content.delete` | same |
+| `PATCH /v1/article/{id}/publish`, `/unpublish` | `content.publish` | same; `PATCH` never changes `is_online` |
+| `GET /v1/content-type/{key}/entry`, `GET .../entry/{id}` | `content.read` for `{key}` | `own` lists only the caller's entries (total, page, size and `q` follow) and answers 404 `entry_not_found` for another's entry |
+| `POST /v1/content-type/{key}/entry` | `content.create` for `{key}` | `created_by` is the caller |
+| `PUT`, `DELETE .../entry/{id}` | `content.update`, `content.delete` for `{key}` | `own` needs `created_by` to be the caller |
+
+Each action reads its own permission: publish does not imply update, update does not imply read. `own`
+means `created_by` equals the caller; an unattributed item (`created_by` 0) is owned by nobody. A permission
+can also be set for one content type (`content.update:blog`, `content.update:article` for articles); that
+row replaces the wildcard for the type, whether it lowers or raises it, and a `none` row denies. Only the
+wildcard applies to a type with no row. An id that does not exist is 404 even for a caller at `own`. Article responses expose `created_by` to signed-in callers and API keys only (never to anonymous callers), so a client can tell which rows are its own; see `docs/api/articles.md`.
+
+A refusal is 403 `missing_permission` with `X-Missing-Permission` set to the base key (`content.update`,
+never `content.update:blog`). The permission is checked before the id and the body are read, then the scope
+after the lookup, and a refused call writes nothing and records no activity event. The verification and
+token checks still come first. Creating a content type whose key is `article`, `author`, `site`, `media`
+or `user` is 409 `content_type_key_taken`. Owner-only permissions only count on the locked Owner role: the
+same key placed by hand on another role is ignored and `GET /v1/auth/me` does not list it.
+
+## Errors
+Every error is a plain-text body with one sentence; the status is in the HTTP status line. The
+statuses are 400, 401, 403, 404, 409, 429 and 500. Messages are listed on the Integration page.
+
+A caller whose role lacks the permission a route needs gets 403 with the body `missing_permission` and the
+header `X-Missing-Permission` set to the permission key (for example `users.invite`). The role is read on
+every request, so an API key follows the current role of its creator.
+

+# Reading articles
+
+Every route that returns an article accepts the optional `format` query parameter and returns the article body in that format. Articles are stored as HTML (Tiptap output). Storage and the request bodies of `POST /v1/article/` and `PATCH /v1/article/{id}` stay HTML.
+
+`PATCH /v1/article/{id}` takes `body`, `site_id`, `author_ids` (the whole ordered list of author ids, see `docs/api.md`) and the SEO fields listed below, and nothing else. The request must contain at least one of them, and `null` answers `400` except for `cover_image_id` and `social_image_id`. Behaviour change: `{}` and `{"body": null}` used to set an empty body and now answer `400`; send `{"body": ""}` to empty a body.
+
+## Routes that honour `format`
+
+- `GET /v1/article/`
+- `GET /v1/article/{id}`
+- `POST /v1/article/`
+- `PATCH /v1/article/{id}`
+- `PATCH /v1/article/{id}/publish`
+- `PATCH /v1/article/{id}/unpublish`
+
+Anonymous and unverified callers only see online articles, and an offline article answers `404 Article not found`. A verified caller also sees the drafts that `content.read` covers: every draft at `all`, only their own at `own`, and none without the permission. The `all`, `online` and `draft` counts follow the same visible set.
+
+## Pagination, search and counts
+
+`GET /v1/article/` always answers one page inside an envelope, with or without query parameters:
+
+```json
+{
+  "items": [],
+  "total": 30,
+  "page": 1,
+  "size": 25,
+  "counts": { "all": 30, "online": 30, "draft": 0, "suggestions": 4 }
+}
+```
+
+| Parameter | Values | Default |
+| --- | --- | --- |
+| `page` | integer >= 1 | `1` |
+| `size` | `5`, `25`, `50` or `100` | `25` |
+| `q` | up to 200 characters, matched anywhere in the title, ignoring case and accents | none |
+| `status` | `online` or `draft` | none |
+| `site` | the `key` of a site; an unknown key gives an empty page, an empty value is `400` | none |
+| `seo` | `ready`, `suggestions` or `hidden`; any other value, an empty one included, is `400` | none |
+| `sort` | `title`, `status`, `created_at` or `updated_at`, then `:asc` or `:desc` (lowercase, for example `title:asc`) | `updated_at:desc` |
+
+- `items` is `[]` when empty, never `null`. Each item is the article object below.
+- Items follow `sort` (default `updated_at:desc`) across the whole list before paging. `title` ignores case, `status` orders on online state (`status:asc` puts drafts first), and every ordering ends with `id` descending so pages never overlap.
+- `total` is the number of visible articles matching `q` and `status`, before paging. `page` and `size` echo the values applied.
+- `counts` ignores `q`, `status`, `site`, `seo`, `sort`, `page` and `size`, so tab counts do not move while searching. `suggestions` is the number of visible articles whose `seo_status` is `suggestions` (hidden and ready articles and dismissed codes are not counted); it equals the `total` of `?seo=suggestions` sent with no other filter by the same caller. For anonymous and unverified callers `all` equals `online` and `draft` is `0`, and `status=draft` answers `items: []` and `total: 0`.
+- Each item also carries `seo_status` and `seo_suggestions` (see [SEO status and suggestions](#seo-status-and-suggestions)). `seo` filters on the status before paging, so `total` follows it while `counts` do not.
+- A page beyond the last answers `200` with `items: []` and the real `total`.
+- An invalid `page`, `size`, `status`, `sort` or an over-long `q` answers `400` with the plain-text message `The request cannot be processed due to a mismatch in the format of the body.` An invalid `format` is reported first.
+
+Breaking change: this route used to answer a bare JSON array. Clients must read the `items` property.
+
+## The `format` parameter
+
+| Value | `body` | `body_format` |
+| --- | --- | --- |
+| empty or absent | markdown string | `markdown` |
+| `markdown` | markdown string | `markdown` |
+| `html` | the stored HTML string | `html` |
+| `json` | JSON array of blocks | `json` |
+
+Values are case-insensitive. When `format` is repeated, the first value is used. Any other value answers `400` with the plain-text message `The format must be one of: markdown, html, json.` before any article is read or written. An invalid id is reported first, ahead of the format.
+
+Breaking change: the default used to be HTML. Clients that need HTML must send `?format=html`. The web interface does so.
+
+## Article object
+
+```json
+{
+  "id": 1,
+  "title": "Backyard Renovation Update",
+  "body": "## Plan\n\nReplace the **old** deck.",
+  "body_format": "markdown",
+  "is_online": true,
+  "site_id": 1,
+  "created_by": 1,
+  "authors": [],
+  "slug": "backyard-renovation-update",
+  "excerpt": "",
+  "seo_title": "",
+  "seo_description": "",
+  "cover_image_id": null,
+  "cover_image_alt": "",
+  "social_title": "",
+  "social_description": "",
+  "social_image_id": null,
+  "canonical_url": "",
+  "noindex": false,
+  "seo_dismissed": [],
+  "created_at": "2026-03-12T09:14:00Z",
+  "updated_at": "2026-09-10T07:00:00Z"
+}
+```
+
+`created_by` is the id of the user who created the article (`0` when it is attributed to nobody). It is present on every article object (list, read, create and update responses) only when the caller is signed in with a verified session or authenticates with an API key; the key acts as its creator. Anonymous callers, and unverified or stale sessions, get the same object without the field. The SPA reads it to decide which rows a role limited to `own` can edit, delete or publish.
+
+Every single-article read (`GET /v1/article/{id}`, `POST`, `PATCH`, `publish`, `unpublish`) carries the twelve SEO fields. Each item of `GET /v1/article/` carries `slug` and `excerpt` only, and none of the other ten.
+
+## SEO fields
+
+| Field | Type | Limit and rule |
+| --- | --- | --- |
+| `slug` | string | `^[a-z0-9]+(-[a-z0-9]+)*$`, 1 to 100 characters, unique per site. `""` regenerates it from the title. |
+| `excerpt` | string | 300 characters |
+| `seo_title` | string | 120 characters |
+| `seo_description` | string | 320 characters |
+| `cover_image_id` | number or `null` | an existing image id (`0` is refused) |
+| `cover_image_alt` | string | 200 characters, independent of the cover |
+| `social_title` | string | 120 characters |
+| `social_description` | string | 320 characters |
+| `social_image_id` | number or `null` | an existing image id (`0` is refused) |
+| `canonical_url` | string | `""` or an absolute `https` URL with a host, at most 2048 characters |
+| `noindex` | boolean | only a flag: the article stays online |
+| `seo_dismissed` | array of strings | any of `title_long`, `title_empty`, `desc_short`, `desc_long`, `cover_alt`, `cover_none`, `slug_long`, `no_au`, `no_h`, `body_alt`, `short`; duplicates are collapsed, order kept |
+
+Limits are counted in characters (runes), not bytes. Absent fields are untouched; text fields and `noindex` are cleared with `""`, `false` and `[]`, the two image ids with `null`.
+
+### The slug
+
+A slug is unique per site (`site_id`, `slug`), never globally. At creation it is generated from the title: lowercase, accents folded, every run of other characters becomes one dash, dashes trimmed, cut to 100 characters without a trailing dash, and `article` when no letter or digit is left. A slug already used on the site gets `-2`, `-3`... silently, the base being truncated so the result fits 100 characters. The same rule backfills existing articles on the first start after the upgrade, in id order within each site.
+
+Editing a slug that another article of the target site already uses (the new site when `site_id` is sent in the same request; moving an article also re-checks its current slug there) answers `409` with the plain-text body `slug_taken`, and the response header `X-Slug-Suggestion` holds the first free `<slug>-N` from 2 on that site, fitting 100 characters. `X-Slug-Suggestion` is set on this `409` only and on no other response. A request with `slug: ""` that regenerates onto another article's slug is refused the same way and never suffixed silently. Re-sending an article's own slug is not a conflict. A refused request changes nothing.
+
+Publishing, unpublishing and `noindex` never change a slug. A deleted article frees its slug.
+
+## Resolved SEO object
+
+`GET /v1/article/{id}/seo` answers the data a frontend renders in its `<head>`. Online articles are public; a draft needs a verified session or API key whose role may read it (see [Content permissions](../api.md#content-permissions)) and is otherwise `404 Article not found`. The query is ignored (no `format`). Keys:
+
+`title`, `description`, `canonical_url`, `robots`, `og` (`type`, `title`, `description`, `image`, `image_alt`, `url`, `site_name`, `locale`), `twitter` (`card`, `title`, `description`, `image`, `image_alt`), `image` (`url`, `alt`, `source`), `authors` (`name`, `url`, `same_as`), `published_at`, `modified_at`, `fallbacks` and `json_ld` (a ready schema.org `Article`).
+
+The fallback chain, first non-empty wins:
+
+| Output | Chain | `fallbacks` value |
+| --- | --- | --- |
+| `title` | `seo_title`, then the article title, then the site `title_template` (`%title%`, `%site%` replaced by `site_name`, result trimmed) | `seo_title`, `title` |
+| `description` | `seo_description`, `excerpt`, the first sentence of the body (tags removed), the site `default_description` | `seo_description`, `excerpt`, `body`, `site`, `none` |
+| `image` | `social_image_id`, `cover_image_id` (with `cover_image_alt`), the site `default_social_image_id`; `url` is the site `base_url` plus the image path, `""` and `none` when there is none | `social`, `cover`, `site`, `none` |
+| `canonical_url` | `canonical_url`, then site `base_url` + `/` + `slug` | `canonical_url`, `site` |
+| `robots` | `noindex, nofollow` when `noindex` is true, otherwise from the site `default_robots` (`index, follow` or `noindex, nofollow`) | none |
+| `og` and `twitter` title and description | `social_title` and `social_description`, then the resolved values | none |
+
+`og.type` is `article`, `og.locale` is the site locale (`""` when none), `twitter.card` is `summary_large_image` with an image and `summary` without. `published_at` is the creation time of an online article and `null` for a draft; `modified_at` is `updated_at`. `authors[].url` is the author website (`""` when none) and `same_as` lists the social link URLs only. `json_ld.headline` is the meta title without the site template, and `author`, `image` and `datePublished` are left out when empty.
+
+## SEO status and suggestions
+
+`POST /v1/article/{id}/seo/check` and the list use one rule set. Soft ranges never block saving or publishing; lengths are counted in characters.
+
+| Code | Field | Fires when | `params` |
+| --- | --- | --- | --- |
+| `title_long` | `seo_title` | the meta title (`seo_title`, else the title) is over 60 characters | `length`, `max` |
+| `title_empty` | `seo_title` | the meta title is empty after trimming | none |
+| `desc_short` | `seo_description` | the resolved description is under 70 characters | `length`, `min` |
+| `desc_long` | `seo_description` | the resolved description is over 160 characters | `length`, `max` |
+| `cover_alt` | `cover_image_alt` | there is a cover and its alt text is empty | none |
+| `cover_none` | `cover_image_id` | there is no cover | none |
+| `slug_long` | `slug` | the slug is over 75 characters | `length`, `max` |
+| `no_au` | `author_ids` | no author is credited | none |
+| `no_h` | `body` | the text has at least 1000 characters and no `h2` to `h6` | none |
+| `body_alt` | `body` | an image of the body has no alt text | `count` |
+| `short` | `body` | the text has fewer than 300 characters | `length`, `min` |
+
+Suggestions come in that order. Codes in `seo_dismissed` are never reported or counted. The status is `hidden` when `noindex` is true, else `suggestions` when at least one suggestion remains, else `ready`. The list items carry `seo_status` and `seo_suggestions` (the count, also for a hidden article).
+
+## Markdown output
+
+Headings, bold, italic, links, bullet and ordered lists, blockquotes, fenced code blocks, rules, images and inline code are converted. Anything else is reduced to its text. `script` and `style` content is removed, and the source HTML is never passed through; the only HTML in the output is the alignment wrapper described below. List indentation attributes are dropped. Links with a scheme other than http, https, mailto or tel are reduced to their text. Characters that markdown would read as formatting (`*`, `_`, `` ` ``, `[`, `]`, `<`, `\`) and line starts that would read as a heading, list, quote or rule (`#`, `-`, `+`, `>`, `1.`) are backslash-escaped, so plain text stays plain text. A line break becomes a backslash followed by a newline.
+
+### Text alignment
+
+Markdown has no syntax for alignment, so centered, right-aligned and justified paragraphs and headings are wrapped in a `div` with an inline style. The blank lines around the content make CommonMark parse the inside as markdown:
+
+```markdown
+<div style="text-align: center">
+
+A **centered** paragraph
+
+</div>
+```
+
+Left alignment is the default and produces no wrapper. Your markdown renderer must allow raw HTML for the alignment to show (`html: true` in markdown-it); otherwise the wrapper tags appear as text, and a client that does not want them can request `?format=json` instead, where the alignment is a field.
+
+## JSON block schema
+
+`body` is a native JSON array. Every block has a `type`.
+
+| Block | Fields |
+| --- | --- |
+| `heading` | `level` (1 to 6), `align` (only when `center`, `right` or `justify`), `children` (text nodes) |
+| `paragraph` | `align` (only when `center`, `right` or `justify`), `children` (text nodes, empty array for an empty paragraph) |
+| `list` | `ordered` (boolean), `items` (array of items, each an array of blocks) |
+| `blockquote` | `children` (blocks) |
+| `code` | `language` (empty string when unknown), `text` |
+| `hr` | none |
+| `image` | `src`, `alt` (empty string when missing) |
+
+Text node: `{"type":"text","text":"...","marks":[...]}`. `marks` is always an array, listed outermost first. A mark is `{"type":"bold"}`, `{"type":"italic"}` or `{"type":"link","href":"..."}`. A line break becomes a `"\n"` inside the text. Adjacent text with identical marks is merged. Inline code, underline, strike-through and other formatting degrade to plain text. An image inside a paragraph becomes its own block and splits the paragraph. An empty body is `[]`.
+
+Example for `<h2>Plan</h2><p>Replace the <strong>old</strong> deck.</p>`:
+
+```json
+[
+  {"type":"heading","level":2,"children":[{"type":"text","text":"Plan","marks":[]}]},
+  {"type":"paragraph","children":[
+    {"type":"text","text":"Replace the ","marks":[]},
+    {"type":"text","text":"old","marks":[{"type":"bold"}]},
+    {"type":"text","text":" deck.","marks":[]}
+  ]}
+]
+```
+
+## Errors

+### Media purge
+
+`internal/domain/purge` holds `Settings` (automatic purge on or off, interval of 1 to 365 days, `last_purge_*` history, `enabled_at`), the `Repository` interface (`Get` returns the defaults when nothing was saved, `Save`, and `SaveLastRun`, which writes only the `last_purge_*` columns so a settings change made during a run is never overwritten) and the sentinels `ErrInvalidPurgeInterval`, `ErrPurgeConflict` (stale fingerprint) and `ErrPurgeBusy` (a run is already in progress). `Settings.NextPurgeAt` is `max(last_purge_at, enabled_at)` plus the interval when automatic purge is on, and null otherwise. The settings live in a single-row `purge_settings` table (`models.PurgeSettings`, `mappers.PurgeSettings*`, `persistence.PurgeSettingsRepository`), created by `AutoMigrate`.
+
+The use cases `GetPurgeSettings`, `UpdatePurgeSettings`, `PreviewPurge` and `RunPurge` depend only on domain interfaces, an injected clock and an injected `*log.Logger`, so a scheduler can call them. `PreviewPurge` and `RunPurge` share one plan (`purgePlan.go`): a duplicate group (same non-empty sha256) is planned only when a copy is used in an article, the most used copy is kept (ties: oldest `created_at`, then lowest id) and every other copy is merged into it. The fingerprint is a SHA-256 over the planned groups. `RunPurge` takes a non-blocking in-process lock (`ErrPurgeBusy` for a concurrent call), refuses a non-matching fingerprint with `ErrPurgeConflict`, merges group by group with `MergeMedia` (a failing group is counted and skipped), unions the `UpdatedArticleIDs` of the fully merged groups, and records `last_purge_*` after every run.
+
+#### Automatic purge scheduler
+
+`PurgeSchedulerUseCase.Tick(now)` returns the `purge.RunResult` of the run, whether it ran and an error. It reads the purge settings on every call and runs `RunPurge.Run(nil)` (no fingerprint) when `Settings.NextPurgeAt()` is set and `now` is not before it. It never writes settings: only `RunPurge` records `last_purge_*`, through `SaveLastRun`, which moves the anchor forward even when nothing was purged. The runner in `internal/infrastructure/scheduler` calls `Tick` and logs one line with `groups_purged`, `merged`, `articles_updated` and `failed_groups` when a run happened. It calls `Tick` once after a startup delay of 1 minute, which catches up a run missed during downtime in a single purge, then once every hour. `api/dependecyInjection.go` builds it and `cmd/server/main.go` starts it with the signal context of the server. Changes to the settings apply on the next tick, with no restart.
+
+- Overlap guard: a manual run holds the `RunPurge` lock, so `Tick` returns `ErrPurgeBusy` at once. The runner treats it as a skip, logs nothing and re-evaluates at the next tick.
+- Failures: any other error is logged and the loop keeps going. There is no retry inside a tick; the next hourly tick evaluates the schedule again.
+- Shutdown: on SIGINT or SIGTERM the runner stops taking ticks and waits, with no time limit, for a `Tick` in progress. `main` waits for the runner to return before the database is closed.
+
+`middleware.RequireOwnerOrAdmin` lets only the roles owner and admin through (403 otherwise, including an empty role). The media router mounts these routes after the verified chain and before the `/{id}` routes:
+
+| Route | Purpose |
+|---|---|
+| `GET /v1/media/purge-settings` | Settings with `next_purge_at`. |
+| `PATCH /v1/media/purge-settings` | Partial update of `auto_purge_enabled` and `auto_purge_interval_days`. |
+| `GET /v1/media/purge-preview` | Groups, copies, distinct articles, the first 5 groups, `more` and the fingerprint. |
+| `POST /v1/media/purge` | Runs the purge. Optional `fingerprint`; 409 when stale or when a run is in progress. |
+
+### Sessions and personal data retention
+
+A session is an HS256 token from `api/pkg/authtoken`. `Encode` adds a random `jti` and an `exp` 24 hours ahead; `Decode` refuses a token without `exp`. `authtoken.WithRevocationStore` plugs in `useCases.SessionRevocationUseCase`, which stores a `session.Revocation` (`jti`, `exp`) through the `internal/domain/session` `Repository` (`persistence.RevokedSessionRepository`, table `revoked_sessions`). `LoginHandler.Logout` revokes the presented token; from then on `Decode` answers `ErrRevoked` for it, and a store that cannot be read makes every token invalid rather than valid. Revoking every session of a user stays the job of `token_version`, bumped by a password reset.
+
+`useCases.EnforceRetentionUseCase.Tick(now)` deletes revocations past their expiry, unverified accounts 7 days after their code expired (`user.UnverifiedRetention`) and invites 30 days after they expired or were accepted (`invite.Retention`), and returns a `retention.Result`. `scheduler.NewSystemRetentionRunner` calls it one minute after startup and then hourly, logs one line only when something was removed, and stops with the other runners on shutdown.
+
+Uploads go through the `image.MetadataStripper` port before they are measured for size, hashed and stored. `imaging.MetadataStripper` walks the JPEG segments, PNG chunks and WebP RIFF chunks without re-encoding pixels, drops metadata, keeps colour profiles and re-adds an orientation-only EXIF block when the photo was rotated. A container it cannot walk fails the upload with `image.ErrImageUnreadable`.
+
+### Activity log
+
+`internal/domain/audit` holds the append-only `Event` (actor, target and failure-reason snapshots, outcome, security flag, source, ip, user agent, `params` and `changes`), the closed vocabularies (actor type, category, outcome, source, change kind), the `Filter`, `Summary` and `Settings` types, the `Repository` interface (`Append`, `List`, `Summary`, `DeleteOlderThan`: no way to edit or delete one event), the `SettingsRepository` (`Get`, `SaveRetention`, `SaveLastCleanup`; no row means 90 days) and the sentinels `ErrInvalidFilter`, `ErrInvalidRetention`, `ErrInvalidEvent` and `ErrActorNotAllowed`. The `Recorder` port is `Record(ctx, event)`; it returns nothing, so a caller can never fail on it.
+
+`internal/infrastructure/auditing.Recorder` is the adapter. It fills a missing actor, source, ip and user agent from the `audit.Origin` carried by the request context, stamps `created_at` from the injected clock in UTC, bounds long names, drops an event outside the vocabulary, and recovers from any error or panic of the repository by writing one line to the process log (the action and the error only). `middleware.AuditContext` builds the origin after the credential middleware: a session gives a `user` actor and source `web`, an API key an `api_key` actor and source `api_key`, no valid credential an `anonymous` actor; the ip is the peer address, or `X-Real-IP` when the peer is a trusted proxy; the user agent is cut to 255 characters. Use cases that produce events (authenticate and logout, password reset request and completion, API key create and revoke, retention change, cleanup) take the context and an `audit.Recorder`; secrets (passwords, raw keys, reset codes, tokens and their hashes) are never put in an event or in its log line.
+
+Persistence is `models.AuditEvent` (`audit_events`, indexes on `created_at`, `(actor_type, actor_id, created_at)` and `(category, created_at)`; `params` and `changes` are JSON text) and `models.AuditSettings` (one row), both in `AutoMigrate`. The queries use only portable SQL (`LOWER(...) LIKE ... ESCAPE '!'`, `COUNT(DISTINCT ...)`, `CASE` sums), so they run on SQLite, MySQL/MariaDB and PostgreSQL. The summary splits the range into seven equal buckets, oldest first.
+
+The use cases `ListActivity`, `GetActivitySummary` and `ExportActivity` turn the raw query into a domain filter (`range` defaults to 7 days; `custom` needs two dates, `to` included), scope a caller who is not owner or admin to its own events, and resolve `target.exists` at read time. The export reads the log through `List` in pages of 500 and writes the CSV with `encoding/csv`. `/v1/activity` and the settings `PATCH` sit behind `RequireSession`, the verifier, the current-token and verified-user checks; summary and export also behind `RequireOwnerOrAdmin`, the settings `PATCH` behind `RequireOwner`.
+
+`CleanupActivityUseCase.Tick(now)` follows the `PurgeScheduler` model. With a retention of 0 it never runs. Otherwise it is due once a day, at or after 03:00 in the location of `now` and when the last cleanup is before today's 03:00. It deletes events older than `now` minus the retention days (never newer than 24 hours), records the run (`activity_last_cleanup_at`, `activity_last_cleanup_removed`) even when nothing was removed, and only then records a `system.activity_cleanup` event when something was removed. A failing delete returns the error and leaves the last-cleanup fields as they were, so the next tick retries. `scheduler.Runner` now wraps a task with a label: `NewRunner` keeps the purge behaviour and log line, and `NewCleanupRunner` ticks the cleanup. `UseCases.RunSchedulers` runs both runners and `cmd/server/main.go` starts it with the server's signal context.
+
+Producers: `ArticleChanges`, `TextChange` and `BodyChange` in `internal/domain/audit` build the change lists (the body change holds only a signed rune count delta), and `NewTarget` and `ReleaseTarget` build the target snapshots (types `article`, `image`, `user`, `invite`, `api_key`, `release`). The use cases create, edit, publish, unpublish and delete article, upload, rename, delete, merge and purge media, register, verify, update profile, create, cancel, renew and accept invite, check, download and restart take the request context first and an `audit.Recorder` last, and record exactly one event after the change or the refusal (the action catalogue is in `docs/api.md`). Events are never written by handlers, middleware or GORM hooks, and nothing is recorded for reads or for a target that does not exist. `useCases/auditFailures.go` holds the fixed table of failure sentences keyed by domain `Err...` sentinels (matched with `errors.Is`, each at most 255 characters; the restart action overrides `ErrJobInProgress`) with the generic fallback "Something went wrong on our side. Please try again."; raw error text is never stored. The manual purge runs the groups through the non-recording `MergeMediaUseCase.merge`, so only one `media.purge` event is written; `RunPurgeUseCase.Execute` is the non-recording run that `PurgeSchedulerUseCase.Tick(now)` uses to record one `system.media_purge` event with the system actor and `context.Background()`. `StartUpdateDownloadUseCase` hands `context.WithoutCancel(ctx)` to its job goroutine so the `system.update_downloaded` event, written when the job becomes `ready` or `failed`, keeps the origin of the request. `middleware.AuditContext` is mounted on the article, user, media and system routers (after the API key middleware where keys are accepted), so API key calls are attributed to the key.
+
+### Sites
+
+`internal/domain/site` holds the `Site` entity (name, immutable key, normalised base URL, optional default social image, `index` or `noindex` robots, optional locale, the default flag and the computed `article_count`), `NormalizeBaseURL`, `SeedBaseURL`, `NormalizeLocale`, `IsValidKey`, the `Patch` type (with `Nullable` for the two nullable fields), the `Err...` sentinels (`ErrSiteNotFound`, `ErrSiteKeyTaken`, `ErrSiteHasArticles`, `ErrDefaultSite`, `ErrKeyImmutable`, `ErrInvalidSiteURL`, `ErrInvalidLocale`, `ErrUseSetDefault`, `ErrInvalidReassign`) and the `Repository` interface. `persistence.SiteRepository` implements it over `models.Site` (`sites`, unique `site_key`); the single default is kept by the transactional operations `Create` (when flagged) and `SetDefault`, not by an index, and `DeleteMovingArticles` moves the articles and deletes the site in one transaction. Articles carry a `site_id` (indexed, no foreign key, so the SQL stays portable).
+
+The use cases `ListSites`, `CreateSite`, `UpdateSite`, `SetDefaultSite` and `DeleteSite` live in `internal/infrastructure/useCases`; the article, media and purge use cases take the site repository as a required constructor argument, wired by the composition root (new articles take the default site, `UpdateArticle` moves an article and records `site` with site names, the media use cases count, clear and repoint default social images). `api/handlers/site` serves `/v1/site`; reads accept a session or an API key, writes are session only behind `RequireOwner`. `database.Migrate(db, publicURL)` registers the model, seeds one default site from `PUBLIC_URL` when the table is empty and backfills `articles.site_id`.
+
+### Authors
+
+`internal/domain/author` holds the `Author` entity (name, unique slug, bio, optional avatar, optional website, social links, the unique optional `user_id`, `is_linked`, the computed `article_count` and a `user_email` that only owner and admin responses carry), the public `Byline` shape embedded in articles, the `Patch` type, the slug generation (a hand-written Latin diacritic folding table, no external dependency), the value rules (`ValidateBio`, `ValidateURL`, `ValidateLinks`, `IsValidSlug`, `IsValidName`), the `Err...` sentinels (`ErrAuthorNotFound`, `ErrSlugTaken`, `ErrAuthorHasArticles`, `ErrUserAlreadyLinked`, `ErrAuthorAlreadyLinked`, `ErrAuthorRights`, `ErrBioTooLong`, `ErrInvalidURL`, `ErrTooManyLinks`, `ErrInvalidSlug`, `ErrInvalidReassign`) and the `Repository` interface. `persistence.AuthorRepository` implements it over `models.Author` (`authors`, unique `slug` and unique nullable `user_id`) and the ordered join `models.ArticleAuthor` (`article_authors`, unique `(article_id, author_id)` and a `position`); uniqueness is checked inside the transaction and re-explained after a failed write, so a race still answers a domain sentinel, and `DeleteMovingCredits` moves the credits (keeping the position, never duplicating) and deletes the author in one transaction. `ArticleRepository` attaches the ordered `Byline`s to the articles it returns, writes `author_ids` in the article update transaction and removes the credits when an article is deleted.
+
+The use cases `ListAuthors`, `CreateAuthor`, `CreateMyAuthor`, `UpdateAuthor`, `DeleteAuthor` and `GetMyAuthor` live in `internal/infrastructure/useCases`; `CreateArticle` credits the creator's author, `UpdateArticle` validates and records `author_ids`, and the media, purge and activity use cases take the author repository as a required constructor argument (avatars count as media usage, are cleared on delete and repointed on merge and purge). `api/handlers/author` serves `/v1/author`: the list accepts a session or an API key, every write is session only, `POST /` and `DELETE` sit behind `RequireOwnerOrAdmin`, and the edit rights (owner or admin, or the caller's own linked author) are decided by `UpdateAuthor` from the caller the handler passes in. `GET /v1/auth/me` adds the linked author through `GetMyAuthor`.
+
+### Article SEO data
+
+`internal/domain/slug` holds the one slug rule (`Generate`, `WithSuffix`, `IsValid`: lowercase, accents folded, runs of other characters become one dash, 100 characters, a caller-chosen fallback). `internal/domain/article` uses it with the fallback `article` and holds the twelve SEO fields of `Article`, the `Update` fields for them (`Nullable` for the two image ids), `ValidateCanonicalURL`, the eleven dismiss codes and `NormalizeDismissed`, and the sentinels `ErrInvalidSlug`, `ErrSlugTaken` and `ErrInvalidCanonicalURL`. `*SlugTakenError` wraps `ErrSlugTaken` and carries the suggested free slug; the handler turns it into the `X-Slug-Suggestion` header of the 409. `author.GenerateSlug` delegates to the same package.
+
+Slugs are unique per site, enforced by the unique index `idx_articles_site_slug` on `(site_id, slug)`. The use cases decide first: `CreateArticle` generates the slug from the title and takes the first free `-N` on the default site (retrying when the repository reports a race), `UpdateArticle` re-checks the slug on the target site for an edited slug, an empty slug (regenerated from the title) and a move, and computes the suggestion as the first free `-N` from 2, fitting 100 characters. `ArticleRepository` locks the site row, checks the slug inside the transaction and re-explains a failed write as `ErrSlugTaken`. Deleting an article replaces its slug with the tombstone `#deleted-<id>` (it can never match a valid slug) before the soft delete, so the slug is free again while the unique index keeps covering soft-deleted rows.
+
+`database.Migrate` adds the columns with `AutoMigrate`, then runs `BackfillSiteTitleTemplates` and `BackfillArticleSlugs` (only rows with an empty slug, in id order, per site, applying the same rule and the same suffixes, with the tombstone for soft-deleted rows) and only then creates the unique index, so it is idempotent and completes a partly backfilled table. The default `title_template` is written by the backfill and the seed, not by a column default, because the SQLite migrator rebuilds the table on every start when the default contains `%` and `|`.
+
+Media usage has more sources than article bodies: `Article.CoverImageID` and `SocialImageID`, `Author.AvatarID` and `Site.DefaultSocialImageID`. `ListMedia`, the purge plan and `GetMediaUsage` count an article once however many places use the image. `DeleteMedia` clears the cover and social references (`article.Repository.ClearImage`, restored with `RestoreImage` when the delete fails), `MergeMedia` repoints them (`RepointImage`) and counts an article rewritten in its body and its cover once, and `GetMediaUsage` (now built with the site and author repositories) returns articles, authors and sites with `type` and `fields`.
+
+### Image variants
+
+`internal/domain/image` holds the `Variant` entity and its rules (`VariantSettings.Normalized`, the settings `Fingerprint`, `VariantETag`, `ETagMatches`, `IsAnimatedGIF`), the sentinels (`ErrVariantNotFound`, `ErrVariantExists`, `ErrVariantInvalid`, `ErrVariantFormatUnavailable`, `ErrUnknownVariant`, `ErrUnsupportedParameter`, `ErrSourceTooLarge`) and three ports: `VariantRepository` (definitions), `VariantFileRepository` (the index of generated files: variant name, source stored name, cached stored name, content type, size and the settings fingerprint, needed because `Storage.Put` chooses the stored name itself) and `VariantRenderer` (decode a source, encode a variant, report the formats it can encode). `internal/infrastructure/imaging` is the renderer adapter, free of GORM and HTTP; the persistence adapters are `VariantRepository` and `VariantFileRepository` over `models.ImageVariant` and `models.ImageVariantFile`.
+
+Generated bytes are stored only through `image.Storage`, so they follow `STORAGE_DRIVER`, and are never rows of `images`. `ServeVariantUseCase` checks, in order: unsupported parameters, the variant (it must exist and be enabled), the source blob, SVG and animated GIF (served as they are), the size cap, the `If-None-Match` ETag, then the cached file, and generates under an in-process single-flight group keyed by variant, settings and source. A row whose fingerprint no longer matches, or whose blob vanished, is replaced. `UpdateVariantUseCase` purges a variant's files when a rendering setting changes; `DeleteVariantUseCase` and `PurgeVariantUseCase` purge a blob and then its row, so a failed blob delete keeps the row and a retry can finish; `mediaRemover` purges the files of a source before it deletes the source (delete and merge).
+
+The cache screen adds three ports in `internal/domain/image`: `VariantCacheRepository` (unused totals, top sources by bytes and cursor-paged row listing, implemented by the same persistence type as `VariantFileRepository`), `VariantUsageRepository` (one batched write of request times and per-day rejection counts, and the rejection total of a window) and `VariantUsageTracker` (in-memory hits and rejections). `internal/infrastructure/usage.Tracker` implements the tracker; `GetVariantCacheStatsUseCase` and `PurgeVariantCacheUseCase` use the ports only. See [image-variants.md](image-variants.md).
+
+### Image metadata backfill
+
+At boot, `BackfillImageMetadataUseCase` (through `image.Repository.ListMissingMetadata` and `UpdateMetadata`) fills `filename`, `size`, `content_type`, `width`, `height` and `sha256` for image rows that lack them, reading the bytes through `image.Storage` (the files in `UPLOAD_DIR` with the local adapter, the bucket objects with the S3 adapter). It is idempotent, and a row whose file is missing or unreadable is left as it is without stopping the boot. The old `article_id` column and the `article_images` table are kept and never written.
+
+### Roles and permissions
+
+`internal/domain/role` holds the permission catalogue, the built-in roles, one exported constant per catalogue key (`roleKeys.go`, the only place a key is spelled in `api/`) and the pure rules over grants: `ValidateGrants`, `ParseTypedKey` and `Role.GrantSet()`. `Role.GrantSet()` is the single constructor of a `GrantSet` and the only place a stored grant becomes an effective one: it drops unknown keys, typed keys on non-content permissions or with an invalid type key, and owner-only permissions on a role that is not locked; it treats a toggle stored at `own` as `none`; and it resolves duplicate rows to the most restrictive scope. `ValidateGrants` rejects the same rows at write time (`ErrDuplicateGrant`, `ErrOwnerOnlyGrant`, `ErrInvalidScope`, `ErrUnknownPermission`), so a bad row is refused when written and ignored when read. A toggle permission only counts at scope `all`, a scoped one at `own` or `all`. A content permission can be narrowed or widened per content type with a key such as `content.update:blog`; the typed row replaces the wildcard for that type and a `none` row denies. A `GrantSet` is opaque: `ScopeFor(key, typeKey)` resolves wildcard and typed rows, `Permits(key, typeKey, callerID, createdBy)` is the one implementation of own and all (`created_by` 0 and caller 0 own nothing), and `Holds`, `HoldsFor` and `HoldsAll` answer the gate questions. Use cases, handlers and middleware never compare a caller id with `CreatedBy` and never read grant rows. `role.Repository` holds `List` (with every role's grants, in one pass), `Get`, `GetByName`, `Create`, `Save`, `Delete`, `ReassignMembers`, `RemoveTypedGrants` and `MemberCounts` (users grouped by `role_id` plus invites with `accepted_at` NULL grouped by `role_id`, two statements for any number of roles); no role use case scans `user.Repository.GetAll`. `user.Repository` gains `UpdateRole(id, from, to)`, a compare-and-swap on the role the use case read (`ErrRoleChanged`, `ErrUserNotFound`, `role.ErrRoleNotFound`), and `TransferOwnership(from, to, ownerRoleID, formerRoleID)`, which updates both rows in one transaction and fails whole when `from` no longer holds the Owner role (`ErrRoleChanged`) or `to` is missing or unverified (`ErrInvalidTransfer`). `invite.Invite` carries `RoleID`. `ChangeUserRoleUseCase`, `TransferOwnershipUseCase` and the amended invite use cases find the built-in roles with one helper, `builtInRole(roles, name)` (`GetByName`, then `built_in` must be true), and a user's role with `resolveRole`, which reads `role_id` only. `Delete` re-counts users and open invites inside its transaction and `ReassignMembers` moves users and open invites in one transaction and returns their sum. `Save` is version checked: it updates the row only when the caller's version matches, bumps the version, writes `updated_at` and `updated_by`, replaces the grants in the same transaction and returns `ErrRoleConflict` otherwise. It never changes `built_in` or `locked`. `Delete` removes the role and its grants in one transaction and returns `ErrRoleHasMembers` when a user still has the role id; `ReassignMembers(from, to)` changes only `role_id` and returns the count; `RemoveTypedGrants(typeKey)` removes the five `content.*:{typeKey}` rows from every role and bumps the version of each affected role once. The role domain also owns `GrantSet.Covers(other, typeKeys)`, the single implementation of "the caller holds at least these grants" behind the no-escalation rule (it returns an `EscalationError` naming the first offending key), `Role.EffectiveGrants()` (the normalised list used by role responses, the audit diff and `/v1/auth/me`) and `DiffGrants`. The roles API (`/v1/role`) is served by `ListRolesUseCase`, `GetRoleUseCase`, `CreateRoleUseCase`, `UpdateRoleUseCase` (which also resets a built-in role), `DeleteRoleUseCase` and `ReassignRoleMembersUseCase`; they depend on `role.Repository`, `user.Repository`, `contenttype.Repository` and `audit.Recorder` only, and `api/handlers/role` maps their domain errors to the status and code. `DeleteContentTypeUseCase` and `CreateContentTypeUseCase` also take the role repository to clear per-type grants. `DeleteContentTypeUseCase` deletes the type and then clears its typed rows; if that cleanup fails the rows stay, which is safe because the role views (`GET /v1/role`, `GET /v1/role/{id}` and every write response) drop typed rows for content types that no longer exist, so a GET body stays a valid PUT body, and `CreateContentTypeUseCase` clears the rows of a key right after a successful create, before any role can match the new type. A failed create never touches the roles. The repository re-checks the name case-insensitively inside the `Create` and `Save` transactions (`ErrRoleNameTaken`), locks the role row in `Delete` before counting members (a no-op on SQLite) and guards the `ReassignMembers` update with an `EXISTS` on the target role, answering `ErrInvalidReassign` when the target vanished.
+
+Enforcement path. The first middleware that needs the signed-in user (`AuditContext`, `RequireCurrentToken`, `RequireVerifiedUser` or a permission gate) stores a request-scoped holder in the context (`access.WithCurrentUser`), so the user is loaded once per request; an API key adds the one load of its own authentication. `CheckPermissionUseCase` resolves the caller's role with one `role.Repository.Get` (a user whose `role_id` is 0 resolves to `ErrRoleNotFound`, an empty grant set), builds the `GrantSet` from the grants the role already carries and never calls `List`. `RequireTypedPermission` gates a content route on the typed scope before any lookup (the type key is `article` for articles and the `{key}` of the URL for entries) and puts the caller (`access.Caller`: user id and grants) in the context. The optional `OptionalAccess` middleware does the same for the public article routes without ever refusing: no cookie, an unverified user, a stale token or an unresolvable role leave the caller anonymous, and only a role repository failure answers 500. The handler passes the caller to the use case as `useCases.ContentCaller`; the use case loads the article or entry, decides the scope with `Permits` right after the load and before any other lookup or validation, and returns a `role.MissingPermissionError`, which `access.WriteIfMissingPermission` writes as 403 with the base key in `X-Missing-Permission`. Reading follows the same helper: an article is visible when it is online or `content.read` permits its `created_by`, and an entry the caller may not read is `entry.ErrEntryNotFound`. A list under scope `own` is filtered before totals, search and paging. `CreateContentTypeUseCase` refuses the built-in type keys with `contenttype.ErrKeyTaken`.
+
+Built-in reconciliation: `database.SeedBuiltInRoles` creates the three built-in roles when they are missing and never overwrites an edited one. On every start it adds the catalogue keys a built-in role lacks: always for Owner, at scope `all`, and for Admin and Writer only while their version is still 1. It never removes or downgrades a grant and never bumps the version.
+
+Created-by backfill: `database.BackfillCreatedBy` assigns articles (soft-deleted ones included) and entries whose `created_by` is 0 to the first owner by id. A database without an owner is left alone. Entries have no soft delete, so no unscoped query is needed for them.

 - **Production:** a single origin. The SPA calls the API with relative URLs, so the JWT cookie works without CORS. Files under `assets/` are content-hashed by Vite and cached for a year. `index.html` is never cached.
 - **Development:** built with `-tags nofrontend` (`assets_stub.go`, `assets.Dist == nil`). Vite serves the SPA on :5173 and proxies `/v1` to the API on :8080. See [development.md](development.md).
+
+## Storage and database seams
+
+Uploaded images are addressed by a stored name (`<uuid>.<ext>`). `CreateImageUseCase` calls `Storage.Put` (which generates the name), then `Repository.Create` with `Path = /static/uploadedImages/<name>`, and deletes the blob again if the row cannot be created. `DeleteMediaUseCase` and `MergeMediaUseCase` remove the blob first and the row second (`mediaRemover`), so a failed blob delete keeps the row and the delete can be retried. `GET /static/uploadedImages/<name>` is served by `OpenMediaUseCase` through `api/handlers/staticimages`, which uses `http.ServeContent` when the blob is seekable and streams it otherwise; `ErrBlobNotFound` maps to 404 and any other error to 500.
+
+SQL in repositories must run on SQLite, MySQL/MariaDB and PostgreSQL: substring searches use `LIKE ... ESCAPE '!'` through `containsPattern` instead of `instr`. `Settings.DataDir()` is where update state, staging and backups live; it is `DATA_DIR` when set and the directory of `DB_FILE` otherwise, so it does not depend on where the database is.
+
+Three drivers are registered in `database.drivers`: `sqlite` (default), `mysql` (MySQL 8 and MariaDB 11, through `gorm.io/driver/mysql`) and `postgres` (PostgreSQL 16 and 17, alias `postgresql`, through `gorm.io/driver/postgres` on pgx v5); all are pure Go so `CGO_ENABLED=0` and the six release targets still build. `DB_DRIVER` picks one in `databaseConfig` (composition root); an unknown name fails in `database.Connect` with `unsupported database driver "<name>"`. `database.MySQLDSN` and `database.PostgresDSN` build the DSN from separate variables (the PostgreSQL one as an escaped URL with `sslmode`, `timezone=UTC` and a connect timeout), and the driver redacts the password from every error and names only host and port. `Connect` applies the optional `PoolSettings` to any driver. What keeps the repositories identical on both engines, all without touching the domain, use cases or handlers:
+
+- Indexed and unique strings carry `size:` tags in the models (a MySQL index needs a bounded `varchar`). SQLite maps them to the same `text` column, so an existing SQLite file migrates with no schema or row change (`test/sqlite_schema_unchanged_test.go` builds a file from the old model definitions and compares `sqlite_master` and every row).
+- `Migrate` creates MySQL tables with `utf8mb4_bin` (`gorm:table_options`), so `Bob` and `bob` are distinct like in SQLite. The DSN also sets `collation=utf8mb4_bin`.
+- The DSN sets `clientFoundRows=true`: an update that matches a row but changes nothing still reports one affected row, as in SQLite. `InviteRepository.Renew`, `deleteOrNotFound` and `PurgeSettingsRepository.SaveLastRun` depend on that.
+- The Go driver sends a zero `time.Time` as `0000-00-00`, which MySQL's default `NO_ZERO_DATE` rejects, so each session sets `sql_mode` to the server default minus `NO_ZERO_DATE`. Reading `0000-00-00` gives the zero time back.
+- `UserRepository.Create` returns the filled model instead of re-reading it, because MySQL has no `RETURNING`.
+
+On PostgreSQL the MySQL-only table options are not applied, pgx returns `timestamptz` values in the local zone so a query callback in the driver converts them to UTC, and only the `public` schema is used.
+
+Backups are a `domain/update.DatabaseBackup` per driver. SQLite uses `VACUUM INTO`. MySQL uses `DumpBackup`, a pure Go logical dump (`SHOW CREATE TABLE` plus every row, strings escaped and binary values as hex, NULL and zero dates kept) written inside one repeatable-read transaction to `DATA_DIR/backups/renewcms-<time>.sql.partial` and renamed once complete. Any failure removes the partial file and returns an error, so the update download fails instead of claiming a backup. PostgreSQL reuses `DumpBackup` with its own `dumpDialect` (double-quoted identifiers, doubled single quotes, `\x` bytea literals): `CREATE TABLE` is rebuilt from `pg_catalog` (serial columns, defaults, primary key, unique and check constraints), followed by the indexes, the rows and a `setval` per `id` sequence, all inside one repeatable-read read-only transaction. All drivers keep the newest 3 files (`pruneBackups`).
+
+`task test` runs everything that needs no server. The repository contract tests (`test/repository_contract_test.go`) run on SQLite always, and on MySQL when `RENEWCMS_TEST_MYSQL_DSN` points at a server (admin DSN; each test creates and drops its own database). `task test:mysql` starts `mysql:8.4` and then `mariadb:11` in Docker and runs the `MySQL` tests against each. The same contract tests run on PostgreSQL when `RENEWCMS_TEST_POSTGRES_DSN` points at a server (admin DSN, for example `postgres://postgres:pw@127.0.0.1:5432/postgres?sslmode=disable`), and `task test:postgres` starts `postgres:16` then `postgres:17` in Docker and runs the `Postgres` tests against each.
+
+Two storage adapters implement `image.Storage`: `local` (default, files in `UPLOAD_DIR`) and `s3` (`storage.S3Storage`, `aws-sdk-go-v2` over plain HTTPS, pure Go so `CGO_ENABLED=0` still holds). `STORAGE_DRIVER` picks one in `imageStorageConfig` (composition root, from `config.StorageSettings`); `storage.Open` fails with `unsupported storage driver "<name>"` for anything else, and `openImageStorage` panics with the error. The S3 adapter works as follows, with no change to the domain, use cases, repositories or the `staticimages` handler:
+
+- `Open` calls `GetObject` and returns a `Blob` whose `Content` is an `io.ReadSeeker` (`s3Reader`): `Size` and `ModTime` come from `ContentLength` and `LastModified`, the first bytes are read from that response and every `Seek` to another offset makes the next `Read` issue a ranged `GetObject`. `http.ServeContent` therefore answers `Range` (206, 416) and `If-Modified-Since` (304) with no `ETag`. A 404 maps to `image.ErrBlobNotFound`; any other failure is a plain error (500 in the handler).
+- `Put` does one `PutObject` of `<S3_KEY_PREFIX><uuid>.<ext>` with the upload's `Content-Type`. `Delete` treats 404 as success. Names that are not plain file names are never requested, as in the local adapter.
+- Each call has a 30 second timeout to get a response (the body then streams without a deadline) and the SDK default retries. Request checksums are only sent when required, so older S3-compatible servers work.
+- `storage.Open` checks the bucket with `HeadBucket`. The failure text names the bucket and the reason (404, 403, other status or transport error) and never the credentials.
+- At boot, `RunBackfillReportingReads` wraps the storage in a counter for the `BackfillImageMetadataUseCase` run and logs how many images it read; the use case itself is unchanged.
+- Update backups (`DATA_DIR`) never include uploads, whatever the driver.
+
+`task test:s3` starts SeaweedFS in Docker and runs `TestS3StorageIntegration` against it (skipped without Docker, and not part of `task test`). Everything else uses an in-process fake S3 server listening on `127.0.0.1`.
+
+Adding a database driver: implement `database.Driver` (`Open`, and `NewBackup` returning a `domain/update.DatabaseBackup`), register it in `drivers`, then select it in `databaseConfig` in the composition root (and add the env vars to `main.go`, `.env.example` and `configuration.md`). Adding a storage backend: implement `image.Storage`, add a case to `storage.Open`, and select it in `openImageStorage`. No use case, handler or repository changes.

+RenewCMS reads its configuration from environment variables. On startup it also loads a `.env` file from the working directory (or its parent) if one exists. Real environment variables take precedence over `.env`. The parser reads `NAME=value` lines, an optional `export ` prefix, `#` comments (inline ones need a space before the `#`), and single- or double-quoted values (`\n`, `\t`, `\"` and `\\` are unescaped in double quotes). It does not expand `$VARIABLES` and does not support multi-line values. A malformed line makes the whole file ignored, and the server logs the line number.

+| `S3_REGION`            | `us-east-1` | Bucket region. Most S3-compatible servers accept the default.                                                                                                                    |
+| `S3_ENDPOINT`          | *(empty)*   | Host (with optional port) or full URL of an S3-compatible server. Leave empty for AWS S3.                                                                                       |
+| `S3_ACCESS_KEY_ID`     | *(empty)*   | Access key. Set it together with `S3_SECRET_ACCESS_KEY`, or set neither. Setting only one stops the server with an error naming the missing one.                                |
+| `S3_SECRET_ACCESS_KEY` | *(empty)*   | Secret key. Never logged and never in an error message. When both keys are empty, the default AWS credential chain is used (`AWS_*` variables, shared credentials file, instance or task role). |
+| `S3_KEY_PREFIX`        | *(empty)*   | Prefix put before every object key, for example `uploads/`. Include the trailing slash.                                                                                          |
+| `S3_PATH_STYLE`        | `false`     | `true` addresses the bucket as `endpoint/bucket` instead of `bucket.endpoint`. SeaweedFS, MinIO and most self-hosted servers need `true`.                                                  |
+| `S3_TLS`               | `true`      | Only used when `S3_ENDPOINT` has no `http://` or `https://` prefix: `true` means `https`, `false` means `http`.                                                                 |
+
+At startup the server checks the bucket (`HeadBucket`). A missing bucket, refused credentials or an unreachable server stop startup with `Unable to open the image storage: S3 bucket "<name>" is not usable: <reason>`; the error never contains the secret. Each S3 call has a 30 second timeout and the SDK default retries. At boot, images whose metadata is missing are read back from the bucket to fill it; when there were some, one log line says how many.
+
+### Moving existing uploads to a bucket
+
+There is no automatic migration and the database does not change: image rows only hold the stored name, so the same names must exist in the bucket. With the site stopped, copy the files under the same names, under `S3_KEY_PREFIX` if you set one, then set `STORAGE_DRIVER=s3` and restart:
+
+```sh
+aws s3 sync ./data/uploads s3://my-bucket/uploads/
+rclone sync ./data/uploads remote:my-bucket/uploads
+```
+
+Keep `UPLOAD_DIR` until you have checked the site. Moving back is the same copy in the other direction.
+
+### Backups
+
+The pre-update backup covers the database only (and `DATA_DIR` state). Neither the update backup nor the data directory includes uploads, so back the bucket up with your provider (versioning, replication) or with `aws s3 sync` / `mc mirror`.
+
+## Database
+
+SQLite is the default and needs nothing but `DB_FILE`. To run against MySQL 8 or MariaDB 11 instead, set `DB_DRIVER=mysql` and the connection variables below. They are only read (and the four required ones only checked) when `DB_DRIVER` is `mysql` or `postgres`. A required variable that is not set stops the server with `Environment variable DB_HOST is not set` (or `DB_USER`, `DB_PASSWORD`, `DB_NAME`).
+
+| Name                           | Default  | Description                                                                                                                      |
+|--------------------------------|----------|----------------------------------------------------------------------------------------------------------------------------------|
+| `DB_HOST`                      | required | Server host name or IP address.                                                                                                  |
+| `DB_PORT`                      | `3306` (`5432` for PostgreSQL) | Server port.                                                                                                       |
+| `DB_USER`                      | required | Database user. It needs full rights on `DB_NAME`, because the schema is created and migrated at startup.                        |
+| `DB_PASSWORD`                  | required | Database password. It is never logged and never appears in an error message.                                                     |
+| `DB_NAME`                      | required | Name of an existing database. The server does not create it.                                                                     |
+| `DB_TLS`                       | `false`  | `false`, `true`, `skip-verify` or `preferred`. Any other value stops the server with an error naming `DB_TLS` and these values. `true` verifies the server certificate; `skip-verify` encrypts without verifying it. |
+| `DB_SSLMODE`                   | `disable` | PostgreSQL only: `disable`, `require`, `verify-ca` or `verify-full`. Any other value stops the server with an error naming `DB_SSLMODE` and these values. Ignored for SQLite and MySQL (use `DB_TLS` there). |
+| `DB_MAX_OPEN_CONNS`            | `10`     | Maximum open connections in the pool. `0` means unlimited.                                                                       |
+| `DB_MAX_IDLE_CONNS`            | `5`      | Maximum idle connections kept in the pool.                                                                                       |
+| `DB_CONN_MAX_LIFETIME_SECONDS` | `300`    | Seconds after which a connection is closed and replaced. `0` keeps connections forever. Keep it below the server's `wait_timeout`. |
+
+A non numeric (or negative) pool value stops the server with an error naming the variable. There is no DSN variable: the connection string is built from the variables above, with `parseTime=true`, `loc=UTC`, `charset=utf8mb4`, `collation=utf8mb4_bin` and `clientFoundRows=true`. Connecting uses a 5 second timeout, so a wrong host, port, password or database name stops startup quickly with `Unable to open the database`, naming the host and port but never the password.
+
+### PostgreSQL
+
+Set `DB_DRIVER=postgres` (or `postgresql`) and the same connection variables, with `DB_PORT` defaulting to `5432` and `DB_SSLMODE` instead of `DB_TLS`. PostgreSQL 16 and 17 are tested. The database must already exist and `DB_USER` needs full rights on the `public` schema, which is the only schema used. The connection string is built with escaping from the variables (a password may contain spaces, quotes, `@` or `/`), sets the session time zone to UTC and a 5 second connect timeout, and the pool variables above apply. A failure to connect stops startup with `Unable to open the database`, naming the host and port but never the password. Usernames and emails compare case-sensitively, as on SQLite. Before an update download RenewCMS writes a logical dump to `DATA_DIR/backups/renewcms-<time>.sql` (the newest 3 are kept); replay it into an empty database with `psql -f`. For routine backups prefer `pg_dump`.
+
+### MySQL settings
+
+Why those settings: tables are created with the `utf8mb4_bin` collation so that usernames and emails compare case-sensitively exactly like in SQLite (`Bob` and `bob` are different users). The collation of `DB_NAME` itself does not matter, but tables that already exist keep the collation they have. `clientFoundRows` makes an update that does not change a row still count as matched, which the invite and purge-settings code relies on. Each session also drops the server's `NO_ZERO_DATE` SQL mode, because the Go driver sends a zero time as `0000-00-00`. The other strict modes stay on.
+
+With MySQL the data directory (`DATA_DIR`) holds update state and backups only. The pre-update backup is a `renewcms-<time>.sql` logical dump (schema and rows, written by RenewCMS itself, no `mysqldump` needed) that keeps the newest 3. If the dump fails, the update download fails with it. The dump holds your data, such as password hashes, but not the connection password.
 
 Relative paths are resolved against the process's working directory. In production, use absolute paths (see [deployment.md](deployment.md)).
 
+For example, `WorkingDirectory=/var/lib/renewcms` with `DB_FILE=./data/renewcms.db` puts the database in `/var/lib/renewcms/data`. Browser-update `--data-dir` must name that directory, because the app reads helper status and update records beside the database. It is not necessarily `WorkingDirectory` or `ReadWritePaths`. Do not change an existing `DB_FILE` merely to match the helper: that could open a different, empty database. See [browser-update setup](deployment.md#browser-updates).
+
+## Activity log retention
+
+The activity log needs no environment variable. Its retention (an age of 30, 90, 365 days or forever, 90 by default, and an optional maximum size in GB, none by default; whichever limit is reached first removes the oldest events) is a setting the owner changes with `PATCH /v1/settings`, and the daily cleanup runs at 03:00 in the server's time zone (`TZ`, or the host's zone).
+
 ## Adding a variable
 
 1. Read it in the code where it is needed (infrastructure or `api/`, never `internal/domain`).
-2. Register it in [`cmd/server/main.go`](../cmd/server/main.go): add it to `requiredEnvVars` if it is required, or to `envDefaults` if it has a default.
+2. Register it in [`cmd/server/main.go`](../cmd/server/main.go): add it to `requiredEnvVars` if it is required (or to `DatabaseRequiredEnvVars` in `internal/infrastructure/config` if only one database driver needs it), or to `envDefaults` if it has a default.
 3. Add it to [`.env.example`](../.env.example) and to the tables above.
 
 Never hardcode a secret, and never commit `.env`.

+# Custom content types
+
+A content type is a named schema (a key, a name and 1 to 50 fields) stored as one row with the fields as a JSON text column. Entries of every type share one generic table whose `data` column holds a JSON object. No DDL runs at runtime, so creating or changing a type never alters the database schema.
+
+## Icon, built-in types and user lookup
+
+- A content type has an optional `icon`: `null` or a string matching `^[a-z][a-z0-9-]{0,39}$`, validated in the domain (`ErrInvalidIcon`, `400 invalid_icon`) and never checked against a list of known icons. `""` is stored as `null`. `PUT` replaces the icon like the name and the fields, so an absent icon clears it. The column is nullable, so rows stored before it existed read as `null`.
+- `GET /v1/builtin-type` and `GET /v1/builtin-type/{key}` expose a static, read-only catalogue (`internal/domain/builtintype`) of the built-in types `article`, `author`, `site`, `media` and `user` as `key`, `name` and `fields` shaped like content type fields. Owners and admins only. It uses no repository; an unknown key is `404 builtin_type_not_found`. A test checks that every catalogue field key exists in the JSON of the matching entity.
+- `GET /v1/user/lookup?ids=1,2,3` returns `[{id, display_name}]` for any verified user, ordered by id, with the username when the display name is empty. 1 to 100 distinct uint32 ids; anything else is `400`. Unknown ids are omitted.
+
+## Layering
+
+The domain packages `internal/domain/contenttype` and `internal/domain/entry` own the rules: key, name and field validation, entry validation against a schema, the sort whitelist, the page limits and the value equality used by uniqueness. The use cases orchestrate them through the two repositories. The repositories only store and load rows. Entry counting for the "type still has entries" rule lives on the entry repository.
+
+## Known limitations of phase 1
+
+- Uniqueness and schema re-validation are O(n). Checking a unique field loads every entry of the type and compares values in Go, and updating a type with stored entries loads all of them to re-validate. This keeps the SQL portable across SQLite, MySQL/MariaDB and PostgreSQL. The path to fix it is the filterable-fields phase: project the values of unique and filterable fields into an indexed table, so uniqueness becomes an indexed lookup and re-validation can be restricted to the changed fields.
+- Unique values are checked without a transaction, so two concurrent writes of the same unique value can both succeed. A content type key is protected by a unique index, and a violation is reported as `content_type_key_taken` (409).
+- `entry.Repository.DeleteByContentType` is intentionally unused for now. A content type that still has entries cannot be deleted; the method is kept as part of the repository contract for a later cascade.
+- Listing is limited to page 1,000,000 and to page sizes of 100 so that the SQL offset cannot overflow.

+`task release` also signs the release: it writes `bin/checksums.txt` (SHA-256 of the six binaries) and signs it into `bin/checksums.txt.sig` with an Ed25519 key. It refuses to start, before building anything, unless `RELEASE_SIGNING_KEY` points to the private key file and that key matches the public key committed as `internal/infrastructure/update/release.pub`. The one-time setup is below.
+
 The frontend is built once and embedded into every binary. The binaries are static (`CGO_ENABLED=0`), so a Linux build runs on any distribution. The version comes from `git describe`: tag a release (`git tag v1.2.0`) before building, and the binary logs its version at startup.
 
+### Release signing key (maintainers, once)
+
+1. Run `task release:keygen -- <path>` with a path outside the repository (for example `~/.renewcms/release.key`). The private key is written there and never leaves your machine; keygen refuses a path inside the work tree.
+2. Commit the printed public key as `internal/infrastructure/update/release.pub`. A placeholder key (32 zero bytes) prevents signing. Official releases already embed the project's public key; this setup is for release maintainers, not site operators. Never copy the private signing key to a CMS server.
+3. Export `RELEASE_SIGNING_KEY=<path to the private key>` before every `task release`.
+
+To check a download by hand: `go run ./cmd/releasesign verify checksums.txt`, with `checksums.txt.sig` next to it, then compare the binary's hash with the matching line of `checksums.txt`.
+
+### Update checks
+
+The owner's Settings page asks the release feed for the newest release (see `UPDATE_FEED_URL` in [configuration.md](configuration.md)) and keeps the last result in `update-status.json`, next to `DB_FILE`. Back it up with the rest of the data directory if you like; it is rebuilt by the next check when missing. The Settings page reports a newer version. To install it from the browser, set up [Browser updates](#browser-updates) once on the server. In Docker (`RENEWCMS_CONTAINER=true`) browser updates are not offered; Settings tells the owner to pull a new image instead, see [docker.md](docker.md).
+
+### Update downloads
+
+Once the restart helper is installed (it writes `update-helper.json` next to `DB_FILE`), the owner's Update button downloads the new binary, `checksums.txt` and `checksums.txt.sig` from the release feed host over https only, checks the ed25519 signature and the SHA-256, runs the staged binary with `--version`, copies the database into `backups/` (the last 3 copies are kept) and stages everything under `updates/<tag>/`, all next to `DB_FILE`. The job record is `update-job.json`. Nothing running is replaced and the site is not restarted by the download: the owner's Restart button does that, as described in [Browser updates](#browser-updates). `renewcms --version` prints the build version and exits.
+
+### Browser updates
+
+The owner's Restart button installs a downloaded update, or just restarts the site, without touching the server by hand. The app itself stays unprivileged: the systemd unit below keeps `ProtectSystem=strict` and only the data directory (the directory that holds `DB_FILE`) is writable. The only privileged code is a small helper, the same binary started as `renewcms apply-update` by a systemd service that runs as root.
+
+First install v2.6.0-beta or newer manually, back up the database, uploads and current binary, and confirm the app runs as an unprivileged service user. The binary and its parent directory should be controlled by root. Owners can start updates and restarts; admins have read-only update status.
+
+#### Find the actual database directory
+
+The helper's `--data-dir` must be the directory containing `DB_FILE`. Inspect the relevant settings without printing the configuration's secrets:
+
+```sh
+sudo systemctl show renewcms -p User -p WorkingDirectory
+sudo grep '^DB_FILE=' /etc/renewcms/renewcms.env
+```
+
+| WorkingDirectory | DB_FILE | Correct --data-dir |
+| --- | --- | --- |
+| `/var/lib/renewcms` | `/var/lib/renewcms/renewcms.db` | `/var/lib/renewcms` |
+| `/var/lib/renewcms` | `./data/renewcms.db` | `/var/lib/renewcms/data` |
+
+Leave an existing `DB_FILE` unchanged: changing it can open a different, empty database. Configure the helper to match the existing database instead.
+
+#### Enable the helper
+
+For this guide's absolute database path and port 8080, run:
+
+```sh
+sudo /opt/renewcms/renewcms enable-browser-updates \
+  --service renewcms \
+  --binary /opt/renewcms/renewcms \
+  --data-dir /var/lib/renewcms \
+  --port 8080
+```
+
+Replace these flags with your actual paths and port. For the relative database example above and port 8788, use `--data-dir /var/lib/renewcms/data --port 8788`. The absolute executable path works even when `/opt/renewcms` is absent from sudo's PATH.
+
+Without explicit flags, discovery reads `/etc/systemd/system/renewcms.service` and takes its first `ReadWritePaths` entry as the data directory. It does not resolve `DB_FILE`, so explicit flags are necessary when these directories differ or the unit lives elsewhere. The port comes from `--port`, else `PORT` in the unit's `EnvironmentFile`, else 8080. The helper polls `/healthz` on `127.0.0.1` at that port. It then:
+
+- writes `renewcms-update.path` and `renewcms-update.service` next to your other units in `/etc/systemd/system` (no secret and no environment value goes into them);
+- runs `systemctl daemon-reload` and enables and starts the path unit;
+- writes `update-helper.json` in the data directory last, so the Settings page only offers Update and Restart once everything else worked.
+
+Running it again rewrites the units and the status file to the current values. If a step fails, the units it wrote are removed again and `update-helper.json` is not written.
+
+#### Verify setup and test a plain restart
+
+For the layout above, run these checks, substituting your service user and database directory if different:
+
+```sh
+systemctl is-active renewcms-update.path
+systemctl is-enabled renewcms-update.path
+sudo systemctl cat renewcms-update.service
+sudo -u renewcms cat /var/lib/renewcms/update-helper.json
+```
+
+Expect `active`, `enabled`, an `ExecStart` with the correct paths and port, and readable JSON. Reload Settings as owner. With no update waiting, Restart should appear. Press it, confirm the plain restart dialog, and expect the overlay followed by the site returning and a “Site restarted” message.
+
+Then run:
+
+```sh
+systemctl is-active renewcms
+sudo cat /var/lib/renewcms/update-result.json
+sudo cat /var/lib/renewcms/update-running.json
+sudo journalctl -u renewcms-update.service -n 30 --no-pager
+curl --retry 5 --retry-connrefused --retry-delay 2 -fsS http://127.0.0.1:8080/healthz
+```
+
+Expect an active app service, result `kind: restart` with `outcome: succeeded`, the installed version and a new process in `update-running.json`, and health response `ok`. Check `/healthz` through your public HTTPS hostname too. A brief connection refusal during startup can be transient. The oneshot helper normally becomes inactive after success; the path unit stays active.
+
+#### Install a future update
+
+When a newer signed release exists, check for updates in Settings, read its notes and click Update. The site stays online while the files are downloaded, verified and backed up. Wait for Ready to install, then click Restart and confirm installation. Afterwards, check the version in Settings, public health, the helper journal and `update-result.json`: expect `kind: update` and `outcome: succeeded`.
+
+On the latest release you can test only a plain restart. Test installation, forced rollback and hostile-file cases on an isolated Linux/systemd machine with its own data and service. The helper unit names are fixed, so setting up another instance on the same machine replaces that machine's existing helper configuration.
+
+#### Troubleshooting
+
+- **Restart is missing:** reload Settings, confirm you are owner, and inspect `GET /v1/system/update` in the browser's Network panel. For an idle owner, `can_apply: false` means the app did not detect the helper. Check that `update-helper.json` is beside the actual database and readable by the service user.
+- **Wrong helper directory:** disable the helper with the old `--data-dir`, then enable it with the correct directory and port. Do not change `DB_FILE` to compensate.
+- **Overlay does not clear:** inspect the helper journal, `update-result.json` and `update-running.json` in the actual database directory. Check localhost health on the configured port, then public health through the proxy. Do not cache `/healthz` at the proxy.
+- **Old binary panics on `--version`:** older releases may interpret it as normal startup and require server environment variables. v2.6.0-beta and newer print their version without loading configuration. A separately launched process failing this way does not stop the systemd service.
+- **Download or verification fails:** inspect the app journal. All assets and redirects must use HTTPS on the configured feed host. The release must include the six binaries, `checksums.txt` and `checksums.txt.sig`.
+- **Update rolls back:** check the previous version and helper journal. Automatic rollback restores the binary, not the database; schema changes still require a recovery plan.
+
+#### Disable the helper
+
+Use the same database directory you supplied when enabling it:
+
+```sh
+sudo /opt/renewcms/renewcms disable-browser-updates \
+  --service renewcms \
+  --data-dir /var/lib/renewcms
+```
+
+This stops and disables the path unit, removes both unit files and `update-helper.json`, and runs `systemctl daemon-reload`. The restart request, result, staged files and backups stay. `can_apply` becomes false: Settings shows “Not prepared” when an update is available, or “You're up to date” without Restart otherwise.
+
+How it works: pressing Restart makes the app write `update-restart-request.json` in the data directory. The path unit notices it and starts the helper, which deletes the request, checks the staged files again, installs the update, restarts the service and waits up to 60 seconds for the site to answer `/healthz` and for the new process to write `update-running.json`. The helper writes its outcome to `update-result.json`; the Settings page reads it. The technical reason of a failure goes to the journal only (`journalctl -u renewcms-update`).
+
+Files in the data directory:
+
+| File | Written by | What |
+|------|------------|------|
+| `update-restart-request.json` | the app | The request: `kind` (`update` or `restart`), `tag` (updates only), `requested_at`, `requested_by`. The helper deletes it first. |
+| `update-result.json` | the helper | The outcome: `running`, `succeeded`, `rolled_back` or `failed`, with `kind`, `tag`, `from_version`, `started_at`, `finished_at`. It stays until the next download or restart. |
+| `update-helper.json` | `enable-browser-updates` | Marks browser updates as set up (`version`, `service`, `binary`, `data_dir`, `installed_at`). |
+| `update-running.json` | the server, at every start | `version`, `pid` and `started_at` of the running process. The helper uses it to tell a new process from an old one. |
+
+What is supported and what is not:
+
+- Linux with systemd only. Not Windows, macOS, Docker or other init systems: there the command refuses with a clear message and the Settings page keeps showing "Not prepared".
+- Before the swap the helper copies the staged files into a private temp directory, checks the signature and the SHA-256 on that copy and installs the copy. It refuses symbolic links under `updates/` and on the request file.
+- The previous binary is kept as `<name>.previous` next to the binary, and the update download keeps a database backup in `backups/`.
+- If the new version does not come up within 60 seconds, the helper puts `<name>.previous` back, restarts the service and records `rolled_back`. If even that fails the result is `failed` and the journal says so loudly.
+- A plain restart (no update waiting) restarts the service the same way and records `succeeded` or `failed`; no binary is replaced.
+- Only the owner can press Restart. The site is unavailable for about 10 seconds.
+
+#### Verification status
+
+A real v2.6.0-beta plain browser restart was confirmed on Linux/systemd on 2026-10-02: the path unit triggered the helper, a new server process started, the result was `succeeded`, and public health returned `ok`. Real signed installation, forced rollback and adversarial filesystem checks remain unverified. The manual cases are listed in [the restart QA procedure](../features/updates_restart_helper.qa.md).

 ## 2. Lay out the server
 
 The following is a suggested layout for Linux:
@@ -130,8 +270,59 @@ If RenewCMS runs on the same host as the proxy, consider firewalling port 8080.
 
 Either way, set `TRUSTED_PROXIES` (see [configuration.md](configuration.md)) to the proxy's own address as seen by RenewCMS, typically `127.0.0.1` when the proxy and RenewCMS share a host, so the login/password-reset rate limiter honors the forwarded client IP instead of the proxy's own address.
 
+### Security headers
+
+RenewCMS sends `Content-Security-Policy` (including `frame-ancestors 'none'`), `X-Content-Type-Options`, `X-Frame-Options`, `Referrer-Policy` and `Cross-Origin-Opener-Policy` itself, so the proxy doesn't need to add them. With `ENVIRONMENT=production` it also sends `Strict-Transport-Security: max-age=31536000` (browsers ignore it over plain HTTP, so serve the site over HTTPS only). Don't add the same headers in the proxy, or they will be duplicated.
+
+The CSP serves fonts from `'self'` only (the SPA bundles its fonts, so no visitor IP address is sent to a font CDN) and allows `https:` images, because articles may embed remote images. `style-src` keeps `'unsafe-inline'` for the article editor; `script-src` is `'self'` only.
+
+## Using MySQL or MariaDB
+
+SQLite is the default. To use an existing MySQL 8 or MariaDB 11 server instead, create an empty database and a user with full rights on it, then set in `/etc/renewcms/renewcms.env`:
+
+```sh
+DB_DRIVER=mysql
+DB_HOST=db.example.com
+DB_USER=renewcms
+DB_PASSWORD=<generated password>
+DB_NAME=renewcms
+DB_TLS=true
+DATA_DIR=/var/lib/renewcms
+```
+
+`DB_FILE` is then ignored. `DATA_DIR` is where update state, staged updates and backups live, so give it the same value as the helper's `--data-dir` (see [browser updates](#browser-updates)). Use `DB_TLS=true` (or `preferred`) whenever the server is not on the same host. Every variable is described in [configuration.md](configuration.md#database). The schema is created and migrated at startup, so the first start on an empty database needs nothing else.
+
+## Using PostgreSQL
+
+To use an existing PostgreSQL 16 or 17 server, create an empty database and a user with full rights on its `public` schema, then set in `/etc/renewcms/renewcms.env`:
+
+```sh
+DB_DRIVER=postgres
+DB_HOST=db.example.com
+DB_USER=renewcms
+DB_PASSWORD=<generated password>
+DB_NAME=renewcms
+DB_SSLMODE=require
+DATA_DIR=/var/lib/renewcms
+```
+
+`DB_FILE` is then ignored, and `DB_PORT` defaults to `5432`. `DATA_DIR` is where update state, staged updates and backups live, so give it the same value as the helper's `--data-dir`. Use `DB_SSLMODE=require` (or `verify-full`) whenever the server is not on the same host. Every variable is described in [configuration.md](configuration.md#database). The schema is created and migrated at startup. Moving an existing SQLite site is a manual procedure like the MySQL one below, and RenewCMS writes a logical `.sql` dump to `DATA_DIR/backups` before each update download.
+
+### Moving an existing SQLite site to MySQL
+
+There is no migration tool. The manual procedure, with the site stopped:
+
+1. Take a backup of the data directory (database file and uploads).
+2. Start RenewCMS once on the empty MySQL database so it creates the schema, then stop it.
+3. Export the rows from the SQLite file with `sqlite3 renewcms.db .dump`, keep only the `INSERT INTO` statements for `articles`, `images`, `users`, `invites`, `api_keys` and `purge_settings`, and import them into MySQL. Quoting and date formats differ between the two engines, so check a sample first: SQLite writes times such as `2026-01-02 03:04:05.123456789+00:00`, and the `+00:00` suffix must be removed for MariaDB and older MySQL versions. An unset time (`0001-01-01 00:00:00`) is valid as it is in MySQL and is read back as unset.
+4. Copy `uploads/` to the new `UPLOAD_DIR`, set `DB_DRIVER=mysql` and the connection variables, and start the service.
+
+Keep the SQLite file until you have checked the site.
+
 ## Backups
 
+With MySQL, MariaDB or PostgreSQL, back the database up with your server's own tools (for example `mysqldump --single-transaction` or `pg_dump`), plus the uploads directory. RenewCMS also writes a logical dump to `DATA_DIR/backups` before each update download. The rest of this section is about SQLite.
+
 Everything worth backing up is under the data directory. Take a consistent SQLite copy while the service is running:

-| File | What it holds |
+## Pass 3: sites and authors (revised)
+Roles, decisions and the slice order are in `sites-authors-slices.md` (Sites and Authors) and `seo-slices.md` (SEO).
+
+Back-office board groups: Sites, Sites: form, Sites: delete, Authors, Authors: form, Authors: delete, Editor: site and authors, Profile: author profile, Articles: sites and authors. Plus tables: decisions to confirm (13 rows, 5 marked Decided), deviations, API and errors (with the 403 rows), components, accessibility, copy per state.
+- Roles: only creating, editing, deleting and setting the default site are owner only (no sidebar entry or Publishing card for others, 403 page on a direct link). Anyone who can edit an article can set its site and read the site list. Authors: owner and admin manage; other roles read-only, and any role can create and edit their own author (user link locked, no delete).
+- The site key is immutable: read-only with a lock in the edit form; the warning state and dialog are gone.
+- The "Author profile" card is drawn in every existing Profile frame. The "Site and authors" section shows collapsed in every existing Editor frame that has the details sidebar (39 already did; the Loading frame now shows the header with a skeleton summary). The Not found frame has no editor, and on mobile the section is inside the Details sheet. The dedicated groups keep only the feature-specific states.
+- Shared pieces (list, slide-over, delete-with-reassign dialog, slug field, media field) are defined once in `DirectoryFrame`, used by Sites and Authors. The Profile card is defined once in `AppFrame`.
+- States trimmed from 87 to 68 (Sites 9, Sites: form 7, Sites: delete 3, Authors 8, Authors: form 11, Authors: delete 6, Editor: site and authors 16, Profile: author profile 5, Articles: sites and authors 3). Dropped: in-progress and done variants (covered by the button loading pattern and the confirm state's trigger), per-error URL variants, the site picker (same picker as the avatar), manual slug override, long names (merged into Many authors), per-field duplicates. The blocked-delete dialog is one frame, "Server fallback (409)".
+- Only individual states that render a relative time or a countdown carry the "Clock-sensitive" tag (13 states, listed in states.md). No Home or Articles frame is tagged as a whole.
+- Role-restricted variants drawn: read-only Authors list and detail, hidden Sites entry, Sites 403, own-author edit.

Specs: screens/schema.md, content.md, entry.md, schema-later.md, media.md, media-picker.md, and media-field-changes.md for the Media field type.
+- AppFrame gains a Schema item (owner and admin) and a Content group (sidebar and mobile drawer). Nothing else in AppFrame changed.
+- Backend gaps still open: built-in types and fields, display names for created_by and updated_by, a type icon, per-change entry counts.

-## Other boards
+## Fixes applied (pass 2)
+1. Activity export dialog: removed the 42% progress bar, the "large export" state, the server-job copy and the "ready later" toast; added "Preparing download…" (indeterminate), "Download started", failed, nothing to export, 403; CSV only, with one proposed JSON state.
+2. Export dialog and menu copy now match the implemented endpoint (current view with filters, all with optional range).
+3. Articles pagination used `per_page`, sizes 10/25/50, default 10, 32 pages. Now `page`/`size`, 5/25/50/100, default 25, 13 pages; frames, route, URL examples and the change list updated.
+4. The Integration responses table now shows both 400 bodies, `unknown_variant` and `unsupported_parameter`.
+5. `--rc-sand` and `--rc-on-sand` (and the other `--rc-*` tokens) documented as new tokens with light and dark values and their uses.
+6. Raw colours removed from frames: crop handles and mask, tooltip, transparency checker, drag-drop text, selected-row text in MediaFrame, hex in the Prototype. Only the brand mark keeps hex.
+7. ActivityFrame, MediaFrame and VariantsFrame sidebars, topbars and (Variants) mobile drawer deleted; they render inside AppFrame. Activity now follows the sidebar order (Users, Activity, Integration, Settings).
+8. Prototype's own mobile drawer (Home, Articles, Users, Integration only) replaced by AppFrame's drawer.
+9. All code blocks on Integration (auth example, endpoint examples, error response), the base URL, the image URL builder and the one-time API key use CodeSnippet; the three older block styles are gone. CodeSnippet tabs changed from sand pills to the underline style used by tabs elsewhere.
+10. Variant form: mobile full page replaced by a 92% bottom sheet with grabber and close ×; back arrow removed.
+11. Dialog geometry unified (140 px top offset on desktop, flush bottom sheets with grabber on mobile, header 20 24 0, footer secondary left and primary right, close × 44 px on mobile). Changed: Media and Variants dialogs (mobile inset), Activity export (centered, header bar, 480 wide), API keys dialogs (border, 18 px title, 44 px buttons, 120 px offset).
+12. Current page in the paginator: border `--ui-primary` instead of sand (was 1.3:1).
+13. Page padding 24/16 everywhere (was 32 and 24); card padding 16 (was 16 and 20); section gap 16 (was 16, 20, 28); page title 20/28 (was 28/36, 24/32, 20/28); stat figure 24/32; card title 15/24; inputs 32/44 (were 40); one 13 px icon became 14; toast width 356 (was 360, 372).
+14. Copy: "Removed N …" in activity lines became "Deleted N …"; export titles and footers per the glossary.
+15. Media screen: variant count badge added to grid card, list row and mobile row, matching the Variants board.
+16. Editor toolbar on mobile was a cut-down 9-button subset; it now has the full toolbar with sideways scroll and edge fades.
+17. Editor words and characters show "0 words · 0 characters" for a new empty article (was a fallback sample count).
 
-- `source/RenewCMS Prototype.dc.html`: the clickable flows (first run, edit and publish, password reset, delete, session expiry mid-edit).
-- `source/RenewCMS Handoff.dc.html`: the handoff page the first markdown here was generated from. It predates the Users and Profile screens and the invitation email, so it does not list them. Those are written by hand from the Back-office board, `AppFrame.dc.html`, the Prototype and `emails/invitation.html`.
-- `source/RenewCMS Components Product.dc.html`: not regenerated for the new screens either. The matching component changes are in `components.md`, under "Added with the Users and Profile screens".
-- `source/RenewCMS Directions.dc.html`: the three brand directions (history only).
+## Defaults chosen
+- Slide-over rule: only forms with a live preview and record details; on mobile always a 92% bottom sheet.
+- Hover, active, disabled and focus tokens for the matrix (components not specified before): primary hover `--ui-text`, active `--ui-text-toned`; destructive hover opacity 0.85 and active 0.75; disabled 40% (rows 55%).
+- Article pagination: API shape (array body, total in `X-Total-Count`) is a design assumption to confirm with the specifier.
+- The Remove action in the link popover has no confirmation; undo restores the link.
+- The link button is disabled when an image is selected.
+- The tooltip text is "Insert link (Ctrl+K)" and "Insert link (⌘K)" on macOS.
+- Mobile toolbar scrolls sideways; no wrap, no overflow menu.
+- Selected nav items keep the sand fill plus weight 500 and `aria-current` (the fill alone is 1.3:1 in light).
+- Syntax colouring dropped from code samples (one rendering).
+- Export "Download started" offers only Close.
+- New article keeps the title counter "n / 200" (title is limited to 200); the body has no limit and no counter.
+- Page title 20/28, page padding 24/16, card padding 16 (foundations.md).
+- Activity position in the sidebar follows AppFrame.
+- The Prototype shows a toast "Not in this prototype" for sidebar items it has no screen for (Media, Activity, Settings).
+
+## Checks run
+- Opened `RenewCMS Screens Back-office.dc.html` in the preview: it loaded, 38 sections rendered, and I read the DOM of the Activity, Export, Media, Variants, Editor, Integration, Pagination, Picker, Editor picker and States matrix groups to confirm the frames render text and the sidebar. I did not read the console.
+- Computed the contrast table from token values with a script.
+- Searched frames and boards for raw hex and rgb values (only token definitions on the board roots and the brand mark remain), for exclamation marks, Remove and Delete, Update and Save, and per_page.
+- Generated screens/*.md and counted states from the board source; the counts equal the DOM counts for the Back-office board.
+
+## Not done
+- Console errors on the Auth, API keys, Prototype, Foundations and Components boards were not read by me. The delivery check covers the Back-office board; the other boards use the changed frames (AppFrame, ApiKeysPage, AuthCard, MediaFrame) and may need a look.
+- Light and dark were checked for the Back-office board by reading DOM only; I did not view the screenshots of each state at 1440 and 390, so visual regressions from the shell change (slot mode) are possible.
+- Media screen: the "With variants / Without" filter, the "Largest total size" sort and a total-size column exist only on the Variants board states; they are not folded into the Media toolbar.
+- Media picker tiles and the Editor picker were not compared field by field.
+- Duplicated implementations that look alike are not merged in code: toasts (5), badges (2), empty states (2), modal shells (4). Only their visuals were aligned.
+- Hover, active and focus-visible are drawn once in the matrix; screens do not redraw them. Hover and active tokens for destructive buttons use opacity, not a token.
+- Contrast was not computed for every hover and active background, only the pairs listed in foundations.md.
+- The glossary pass was a search for known patterns, not a line-by-line read of every string. Titles in Title Case were not searched.
+- The Components, Handoff and Foundations boards were not updated to mention the new tokens, CodeSnippet or the matrix.
+- Integration still lists "max 10000" for article bodies, as the backend does today (change-list item 11).
+- The sandbox cannot export; no files were bundled.

+# Change list for implementation (status after pass 2; SEO round drawn; cleanup round drawn)
+
+## Cleanup round
+
+1. Editor: site and authors, "Create author" states (4 states, desktop and mobile): the mobile dialog sat under the Details sheet (z-index 50 against 55) and was hidden. It now stacks above the sheet (z-index 60), as the SEO panel does. Full-width bottom sheet with grabber, same fields, Cancel left and "Create author" right (Cancel below on mobile, as the other mobile dialogs). Frame: `DirectoryFrame.dc.html`. The four states share the fix: dialog, "for me", slug taken, failed.
+2. Integration, "6. Errors": the 403 row gets the muted note "Site SEO defaults are owner only. Article SEO fields need only the right to edit the article." The row below shifts down by the wrapped note height (two 18 px lines desktop, three mobile, plus the 2 px row gap). The old inline parenthetical with the same sentence in the 403 cause text was removed, so it isn't said twice. Frame: `IntegrationPage.dc.html`.
+3. Integration, sitemap errors: 404 now shows the body `site_not_found` in code style (was "Site not found"); 400 now shows the generic body-mismatch text used by the other routes (was "Invalid page or size.").
+4. New groups on the Back-office board: "Sites: pagination" and "Authors: pagination", 10 states each (20 states, every one desktop and mobile; light and dark by the theme switch). Back-office total 409 → 429. Same pager as Articles and Media, sizes 5, 25, 50, 100, default 25 (no difference to report). One deviation: on a single page the page-size select is hidden and only "N sites" or "N authors" remains.
+5. Specs: screens/sites.md, screens/authors.md (pager states, URL rules, out-of-range fallback), screens/integration.md, states.md (pagination states, three HTTP rows), components.md (single-page variant, no new component), routes.md (Sites pagination in the URL).
+
+**Backend assumptions to confirm.** GET /v1/site/ takes `q`, `page`, `size` and returns `X-Total-Count` (it returns every site today). GET /v1/author/ gets `page`, `size` and `X-Total-Count` (it has `q`).
+
+**Open points.**
+- Sites has no search field. The two states that need one (empty after search, search resets to page 1) draw the Authors field on Sites with "Search by name or key". Drop those states if you don't want search on Sites.
+- Stale copy found, not changed: GET /v1/article/ on Integration still shows the 400 caption "Invalid page or size." while every other route, and now the sitemap, uses the body-mismatch text. The 404 row of the Errors table still lists only the four resource messages and doesn't mention `site_not_found`. The existing Sites and Authors "Default" frames don't draw the count line. README.md state counts and the "Pagination" notes were not updated (outside this round).
+
+## SEO round: decisions (frames drawn)
+
+**Placement.** A "Search and sharing" section sits under "Site and authors" in the Editor sidebar and in the mobile Details sheet. It is collapsed by default, shows a one-line summary ("Ready", "2 suggestions" or "Hidden from search") and is remembered per browser like Site and authors. It holds only the slug, the full URL and three actions: "Edit search and sharing", "What the frontend gets" and the suggestion list. The fields and live previews open in a slide-over (desktop) or a 92% bottom sheet stacked over the Details sheet (mobile), because the 280 px sidebar is too narrow for previews and the slide-over rule already covers forms with a live preview. The API preview is a 720 px dialog (desktop) or a bottom sheet (mobile).
+
+**Principles.** RenewCMS does not render pages or inject meta tags. Every field is optional and the UI shows its fallback. No scores. Suggestions never block saving or publishing; publishing is allowed regardless. Suggestions are dismissible per article.
+
+**Fallback chain (resolved server-side, shown in the UI).**
+| Output | Order |
+|---|---|
+| title | seo_title, then article title; site title_template applied last |
+| description | seo_description, then excerpt, then first sentence of the body, then site default_description |
+| image | og_image_id, then cover_image_id, then site social image |
+| canonical | canonical_url, then site base_url + "/" + slug |
+| robots | noindex true gives "noindex, nofollow"; otherwise site default_robots |
+| og/twitter title and description | social_title, social_description, then the resolved values above |
+
+**Soft ranges (counters, never blocks).** Meta title 30–60 characters; description 70–160; slug "very long" above 75 characters. Counter turns neutral-warning (`--ui-warning`) outside the range, never red.
+
+**New article fields (PATCH /v1/article/{id}, all optional, snake_case).** `slug`, `excerpt` (max 300), `seo_title` (max 120), `seo_description` (max 320), `cover_image_id`, `cover_image_alt` (max 200; the cover is "ready" only with alt text), `social_title`, `social_description`, `social_image_id`, `canonical_url` (absolute https URL), `noindex` (boolean; only sets a flag in the API, it doesn't change visibility), `seo_dismissed` (string[] of suggestion codes). Slug: lowercase letters, numbers, hyphens; unique per site; 409 `slug_taken` with `suggestion` ("<slug>-2"); auto-generated from the title until edited.
+
+**New site fields (PATCH /v1/site/{id}, owner only).** `site_name`, `title_template` (default "%title% | %site%", must contain %title%), `default_description` (max 320), `social_image_id` (existing), `default_robots` ("index" | "noindex"; existing as robots).
+
+**New endpoints.**
+- `GET /v1/article/{id}/seo`: resolved object, public for online articles, 404 for drafts to anonymous callers. Shape: `{ title, description, canonical_url, robots, og: { type, title, description, image, image_alt, url, site_name, locale }, twitter: { card, title, description, image, image_alt }, image: { url, alt, source }, authors: [{ name, url, same_as: [] }], published_at, modified_at, fallbacks: { title, description, image, canonical }, json_ld }`. `json_ld` is a ready Article object (headline, description, image, author[] with name, url and sameAs from author profile URL and social links, datePublished, dateModified, mainEntityOfPage).
+- `GET /v1/site/{key}/sitemap?page=&size=`: published URLs only, total in `X-Total-Count`. Items: `{ url, modified_at, noindex }`. Decision: yes, shown on Integration under "Search and sharing" with a copy button; noindex articles are included with the flag so the frontend can skip them.
+- `GET /v1/article/?seo=ready|suggestions|hidden`: filter behind "Needs attention" (suggestions) with `seo_status` and `seo_suggestions` (count) added to list items.
+
+**Articles list.** Quiet indicator inside the Status cell (and under the title on mobile cards): nothing when ready, a lightbulb chip "N" for suggestions, an eye-off chip "Hidden" for noindex. Toolbar gets a "Needs attention" toggle next to search; tabs and counts are unchanged. It behaves the same on a single-site install (independent of the Site filter, which stays hidden).
+
+**Authors.** No change to the Authors screen. Profile URL (website) and social links feed `authors[].url` and `same_as`, and JSON-LD `author[].sameAs`; the API preview shows them.
+
+**Permissions.** Anyone who can edit an article edits its SEO fields. Only the owner edits site SEO defaults. 401 and 403 rows join the existing HTTP table: 403 `owner_only` on Site SEO fields, 401 on a missing session.
+
+**Left out on purpose.** Keyword scoring and focus keywords, readability scores, redirects management, schema types beyond Article, hreflang, robots.txt and sitemap rendering (RenewCMS only provides data), automatic image generation for social cards.
+
+**Open questions.**
+1. Is `slug` immutable after first publish, or can it change (and break URLs with no redirects)?
+2. Does the API return the SEO object for drafts to authenticated callers (for frontend previews)?
+3. Should noindex articles be excluded from the sitemap endpoint instead of flagged?
+4. Is title_template applied by the API (resolved title) or only returned for the frontend to apply?
+5. Backfill: generate slugs for existing articles from their titles at migration, with `-2` suffixes on conflicts?
+6. Should excerpt be exposed in the list payload as the article teaser?
+
+**Status.** Frames drawn on the Back-office board (groups: Articles: search status, Editor: search and sharing, Editor: what the frontend gets, Sites: SEO defaults), Integration page group added, specs updated. Placement rationale: the sidebar holds only the summary, address and suggestions because it is 280 px wide; previews and fields need a slide-over.
+
+
+Ordered by implementation dependency: tokens and shell first, then shared components, then screens. "Frontend only" means no backend work is needed.
+
+| # | Screen | Change | Done in design? | Needs backend (yes/no, what) | Needs new tokens or components | Frontend only |
+|---|---|---|---|---|---|---|

+| 9 | Image variants | Variant form as slide-over (desktop) and tall sheet (mobile) | Yes | No | None | Yes |
+| 10 | New article | Title only. Body removed from the modal; the editor opens straight away | Yes | Maybe: confirm `POST /v1/article/` accepts an empty `body` (it is "required" today); otherwise the frontend sends an empty string | NewArticleModal | Yes if empty body is accepted |
+| 11 | Editor | Remove the 10,000 character limit, counter, limit and over-limit states; neutral count | Yes | Yes: remove the body length validation on `POST /v1/article/` and `PATCH /v1/article/{id}` | EditorStatusBar | No |

+| 13b | Media | Pagination under the grid and list, same Paginator and PageSizeSelect as Articles; `page` and `size` in the URL; saved size preference | Yes (9 states in the Media group) | **Yes:** `page`, `size` on `GET /v1/media/` (replaces `cursor` and `limit`); total in `X-Total-Count`, array body unchanged; Integration reference | None (reuses Paginator, PageSizeSelect) | No |
+| 14 | Activity | Failed-action and security cards as toggles, synced chip and segment | Yes | No | FilterCardToggle | Yes |
+| 15 | Activity | Export menu and dialog, CSV: current view (active filters) and all activity (no filters, optional `from`/`to`). Preparing, started, failed, nothing to export, 403 | Yes | No: `GET /v1/activity/export` is implemented (CSV, synchronous, owner and admin, same filters as the list) | ExportMenu, ExportDialog | Yes |

+| 20 | All | Spacing, type and icon sizes made consistent (foundations.md, "One value per role") | Yes in the frames listed there | No | None | Yes |
+| 21 | Settings, sidebar | Sites screen under Settings → Sites ("Publishing" group); "Publishing" card on Settings. Owner only: hidden for other roles, 403 page on a direct link. Key immutable after creation | Yes | **Yes:** `site` table, GET/POST/PATCH/DELETE /v1/site/ (writes owner only; PATCH rejects a changed key), `reassign_to`, seed from PUBLIC_URL | SitesTable, SiteForm, SlugField (locked variant), ReassignDialog | No |
+| 22 | Sidebar | Authors entry between Media and Users, all roles. Owner and admin manage; other roles read-only list and detail | Yes | **Yes:** `author` table, GET /v1/author/ (any role), POST/PATCH/DELETE (owner and admin; a user may PATCH their own linked author), POST /v1/author/me (any role) | AuthorsTable, AuthorForm, SocialLinksRepeater, MediaField | No |
+| 23 | Editor | "Site and authors" section in every Editor frame (collapsed by default): Site select (any role that can edit the article), reorderable authors, inline create (owner and admin), hint | Yes | **Yes:** `site_id`, `author_ids[]` on PATCH /v1/article/{id} | MetaSection, AuthorList, AuthorSelect, SiteSelect, CreateAuthorHint | No |

+
+## Roles and permissions: screens that change
+
+| Screen | Change |
+|---|---|
+| Sidebar and mobile drawer (AppFrame) | Items are listed per permission, not per fixed role. Writer sees Home, Articles, Media, Authors, Activity and Content. A Roles entry appears under Settings for people who can view roles. |
+| Settings navigation (AppFrame, done) | New "Access" group with a "Roles" item (shield icon) under Settings in the sidebar and the mobile drawer, shown to everyone except the restricted `user` role. "Permissions" is removed. |
+| /settings/permissions | Retired. 301 to /settings/roles. The grid lives in the role editor. |
+| Users (list, invite, row menu) | Role badges, Change role dialog, role picker in invite (default Writer), pending invites show the role, Transfer ownership, protected owner row. |
+| Articles list and Editor | Publish hidden for roles without it; status shows Draft with "Ask an editor to publish." Delete and Edit disabled with a reason when scope is Own and the item is someone else's. |
+| Content entry lists and editor | Same Own rules. View only mark. |
+| Settings pages | Read-only mode with banner for people who can view but not edit. Owner-only actions disabled with an Owner only tag. |
+| Schema | Hidden for roles without Schema view. Read-only for view-only roles. |
+| API keys | Info alert "Keys follow their creator's role", a Follows role column. |
+| Profile | Your role card and See what I can do. |
+| Activity and filters | New event types, role diff in the detail panel. |
+| Error and 403 copy | Two codes and the page-level state added. |
+
+Decisions to confirm:
+| # | Decision made | Alternative |
+|---|---|---|
+| 1 | Content permissions come before General permissions in the editor, because the common case (Contributor) only touches the grid. | General first, as in the brief. |
+| 2 | Writer gets Authors: view and edit own, and Activity: own. | No Authors or Activity access. |
+| 3 | A new role starts with nothing granted; presets fill the grid. | Start from a copy of Writer. |
+| 4 | Own-scope rows others created show "View only" with a lock icon, not a hidden row. | Hide other people's entries. |
+| 5 | Reset to default exists for built-in roles edited by the owner. | No reset. |
+| 6 | Activity own/all scope uses the same None / Own / All control. | Toggle plus a separate scope select. |
+| 7 | Transfer ownership takes effect at once, no email to the new owner. | The new owner must accept. |
+| 8 | A user with Roles: manage cannot edit their own role, even in a custom role. | Allow narrowing only. |

-
-## Product component specs
-
-Extracted from `source/RenewCMS Components Product.dc.html`; open it for the drawings.
-
-## Components: product
-
-These are the RenewCMS components, built from the primitives on the first page . Each one lists the Nuxt UI parts it's made from, its props, emits and slots, every state, and keyboard and responsive behavior. Components marked custom have no Nuxt UI equivalent.
-
-### AuthShell
-
-One centered card for every public screen. The logo sits above the title, and the form or ResultPanel goes in the slot. Footer links and the theme select sit outside the card, so the card itself stays about one task.
-
-Log in Welcome back. Log in to manage your articles.
-
-default slot
-
-Forgot password? System
-
-Built from Custom layout component AuthShell.vue : a UPageCard variant="outline" inside a centered main , with AppLogo , and UColorModeSelect size="sm" in the footer. Forms inside it use UForm rather than UAuthForm , because every screen needs states (such as 403, 429 and an inline login during verification) that UAuthForm doesn't expose.
-
-Props, slots Props title: string , description?: string . Slots default , notice (an alert above the title, for session expired or password changed), footer (links). No emits.
-
-A11y The title is the page's h1 , and document.title becomes "Log in · RenewCMS". On route change, focus moves to the h1 . The logo is alt="RenewCMS" and isn't a link, since there's nothing public to go back to.
-
-Responsive 400 px card from sm up, with its top 12 vh from the top. Below sm , the card loses its border and padding drops to 20 px, filling the screen on --ui-bg , and fields and buttons use xl .
-
-### DashboardShell
-
-The sidebar has four destinations (Home, Articles, Users, Integration), and the user menu sits at its foot. The top bar carries the breadcrumbs and page title. Collapsing the sidebar leaves a 56 px icon rail. Below lg , the sidebar becomes a slideover.

-Mobile top bar. The menu button opens the sidebar as a left slideover.
-
-Built from UDashboardGroup storage="local" › UDashboardSidebar collapsible :resizable="false" :default-size="16" :collapsed-size="4" with the #header (AppLogo), #default ( UNavigationMenu orientation="vertical" :collapsed ) and #footer (UserMenu) slots. Each page is a UDashboardPanel , with a UDashboardNavbar holding UDashboardSidebarCollapse and UBreadcrumb . On mobile, UDashboardSidebarToggle appears and the sidebar's built-in slideover takes over.
-
-UserMenu UDropdownMenu :content="{ side: 'top', align: 'start' }" on a ghost UButton block with a UAvatar and the username. The groups are: the account label; System, Light and Dark as checkbox items; then Log out. There are no profile or password items, because the API doesn't support them. Superseded: see "UserMenu (changed)" under "Added with the Users and Profile screens".
-
-Props, slots No props, because the shell reads the user from the session Pinia store. The navbar reads route.meta.title and route.meta.breadcrumb . Slots navbar-right (page actions on mobile) and default . It shows the offline banner when navigator.onLine is false.
-
-A11y The first Tab stop is a "Skip to content" link. The sidebar is a nav labeled "Main", and the current page gets aria-current="page" . In the collapsed rail, items show tooltips and keep their aria-label . The collapse button carries aria-expanded . The mobile slideover traps focus and closes after navigating.
-
-Bend The active nav item uses a sand fill with ink text instead of Nuxt UI's primary-tinted background and left indicator. The shell is set up for this in ui.config.ts .
-
-### PageHeader
-
-Articles Everything you've written, online and in draft.
-
-Connect your website New article
-
-Articles Everything you've written, online and in draft.
-
-New article
-
-Built from UPageHeader :title :description , with actions in the #links slot. The ui override is { root: 'py-0 border-0', title: 'text-xl', description: 'text-sm text-muted mt-0.5' } , which brings Nuxt UI's marketing-size header down to dashboard density.
-
-Props, slots title , description? , slot actions (the primary action goes last, so it sits on the right), slot meta (for example, a status badge next to the title in the editor).
-
-Responsive Below md , the actions wrap under the text. The primary action goes full width at 44 px, and secondary actions move into the navbar's overflow menu.
-
-### ArticleStatusBadge

-
-Unpublishing…
-
-Built from UBadge . Online: color="neutral" variant="solid" icon="i-lucide-globe" . Draft: color="neutral" variant="outline" icon="i-lucide-pencil-line" . Status is shown by the fill, the icon and the word, never by color alone.
-
-Props online: boolean , size?: 'sm' | 'md' (sm in lists, md in the editor header), pending?: 'publish' | 'unpublish' (shows the -ing label with a spinner while the request runs). No emits, because it isn't interactive.
-
-### ArticleTable
-
-Search, filter tabs, a sortable table and row actions. Everything happens in the browser on the list it has already loaded. Below md , the table becomes a card list with the same data and actions.
-
-All 6 Online 4 Drafts 2
-
-Search by title
-
-Title Status Created Updated
-
-Online Draft
-
-Built from UTabs + UInput type="search" + UTable (desktop), or a custom ArticleCardList of ULink rows (mobile), switched with useBreakpoints at md . Each row has a UDropdownMenu , and the row actions go through useArticleActions() , which shares one set of calls between the table, the list and the editor.
-
-Props, emits Props articles: Article[] , loading: boolean , busyIds: Set<number> . Emits publish(id) , unpublish(id) , delete(article) , copy-url(id) . Search, tab and sort state lives in the URL query ( ?q=&status=&sort= ). Slots #empty , #toolbar-right .
-
-Behavior Search is case-insensitive and ignores accents, and it matches anywhere in the title. It updates on input, debounced 120 ms. Tab counts always reflect the full list. Dates within 7 days are relative ("2 hours ago"); older ones are absolute ("18 Aug 2026"), with the full timestamp in a title attribute. Clicking a row opens the editor, except clicks on the menu.
-
-States Loading (5 skeleton rows), empty, no results, a filter tab with nothing in it, a row busy, an action failed (toast with Retry, row reverts), and a row vanished (a 404 on any action removes the row and shows an info toast). Row actions are never optimistic: the row updates when the 200 arrives.
-
-A11y The table has a visually hidden caption, "Articles, sorted by last updated, newest first". Each row's menu button is named "Actions for How we price a bathroom renovation". After a search, a polite live region announces "3 articles".
-
-### EmptyState
-
-No articles yet Write your first one. It stays a draft until you publish it. New article
-
-No articles match "tiles" Check the spelling, or search for a shorter part of the title. Clear search
-
-No drafts Everything you've written is online. New article
-
-Nothing is online yet Publish a draft and it will appear on your website. Show drafts
-
-Built from UEmpty :icon :title :description :actions variant="naked" , placed in the UTable #empty slot or on the page. The icon tile is overridden to rounded-none bg-elevated .
-
-Props variant: 'no-articles' | 'no-results' | 'no-drafts' | 'no-online' , query?: string . Emits action . Each variant has fixed copy, and the search term is shown in quotes, cut to 40 characters.
-
-A11y The title is an h2 . "No results" is announced through the table's live region. Clear search returns focus to the search field.
-
-### ConfirmDialog
-
-Delete this article? "Winter checklist for timber windows" and its 3 images will be deleted. This can't be undone.
-
-Cancel Delete article
-
-Delete this article? "Winter checklist for timber windows" and its 3 images will be deleted. This can't be undone.
-
-Couldn't delete the article, so it's still there. Try again in a moment.
-
-Cancel Deleting…
-
-Left: default. Right: after a failed attempt (the error appears inline), with the retry running (loading).
-
-Built from UModal opened through useOverlay().create(ConfirmDialog) . open() returns a promise that resolves once the action succeeds or the dialog is cancelled. The action runs inside the dialog, so errors show there instead of in a toast behind the overlay.
-
-Props, emits title , description , confirmLabel , pendingLabel , tone: 'danger' | 'neutral' , action: () => Promise<void> . Emits close(confirmed: boolean) . The delete description comes from the title plus images.length , and reads "and its image" for 1 and just the title for 0.
-
-Other uses Cancel registration: "Cancel your registration?" / "Your account will be deleted. You can register again with the same or a different email." / "Cancel registration" / "Keep my account". Leaving with unsaved changes uses the neutral tone.
-
-A11y role="alertdialog" . Focus starts on Cancel, and Enter doesn't confirm by default. While the action runs, the dialog can't be dismissed, both buttons are disabled, and aria-busy is set. On success, focus goes to the next row, or the page heading if there isn't one.
-
-### ArticleEditor, SaveStatus, PublishControl, CharacterCounter
-
-The editor is made of four components that work together. The header holds the read-only title, status, SaveStatus, Save and PublishControl. A sticky toolbar sits above the writing surface, which uses the content type scale. The counter sits at the foot.

-
-ArticleEditor UEditor v-model content-type="html" :extensions + UEditorToolbar :editor :items layout="fixed" . TipTap v3 StarterKit already includes Underline and Link. TextAlign handles alignment and Image handles images. Formatting is a UDropdownMenu with Paragraph and Headings 1–4 ( h1 is kept because the public site controls how the title appears). Indent and outdent call sinkListItem / liftListItem in lists. For paragraphs, a small custom Indent extension writes data-indent="1–4" , because TipTap has no paragraph indent. Clear formatting runs unsetAllMarks().clearNodes() . The editor surface gets class="article-content" .
-
-Props, emits modelValue: string (HTML), articleId: number , disabled? . Emits update:modelValue , request-image . Exposes insertImage(src, alt) and focus() . The toolbar reflects the active state (bold is on at the cursor) using aria-pressed .
-
-SaveStatus A custom inline span aria-live="polite" , driven by useArticleDraft() : 'clean' | 'dirty' | 'saving' | 'saved' | 'error' . Saved shows the time and switches to "Saved 5 min ago" after an hour. The error state's Retry is a UButton size="xs" variant="outline" . Ctrl/⌘ S saves. Leaving with unsaved changes triggers onBeforeRouteLeave (ConfirmDialog, neutral tone) and beforeunload . There is no autosave , so the owner controls exactly what is sent. The draft is mirrored to sessionStorage so it survives a session expiry.
-
-PublishControl A single UButton . Draft → primary "Publish"; draft with unsaved changes → "Save and publish" (PATCH body, then PATCH publish; if the save fails, it doesn't publish); online → outline "Unpublish". Unpublishing doesn't save pending changes, so the draft edits stay pending. Toasts: "Article published", with the description "Title" is now online. ; "Article unpublished", It's a draft again and hidden from your website.
-
-CharacterCounter A custom component in mono type. Props value: number , max: number , min?: number , warnAt?: number (default 0.9). The title uses [...str].length , so accents and emoji count as one, matching Go's validator, which counts runes. The body uses the HTML string length, which is what the API receives. The warning and error states add an icon and text, not just color. A visually hidden live region announces the change only when a threshold is crossed, not on every keystroke.
-
-Responsive Below lg , the details panel becomes a right slideover, opened with i-lucide-panel-right . Below md , the header wraps: back, title and badge on the first row, then SaveStatus and the counter. Save and Publish move to a sticky bottom bar (44 px). The toolbar scrolls horizontally with fade edges and keeps undo, redo and the image button pinned at the start.
-
-### ImageUploader
-
-Opens from the editor's image button in a small modal. Files are checked in the browser before anything is sent. A JPEG, PNG or WEBP then goes through a crop-and-resize step before it uploads; an SVG skips straight to uploading. After a successful upload the image goes in at the cursor and the modal closes.

-
-Built from UModal title="Add an image" › UFileUpload accept="image/png,image/jpeg,image/webp,image/svg+xml" :multiple="false" layout="list" + UProgress size="xs" . Uploads go through XMLHttpRequest , because fetch has no upload progress, as FormData with the field name file . The 201 location is inserted with insertImage(location, '') .
-
-Crop and resize A JPEG, PNG or WEBP opens on a 640px-wide modal (`md.crop`) between the file picker and the upload, replacing the "Add an image" title with "Crop and resize" and the filename/size as the description. The stage shows the image with the crop frame starting as the whole image: a rule-of-thirds grid (lines at 33.3 %/66.6 %), four 12×12 px corner handles, and a pixel-size label (mono, bottom-left, dark pill) that tracks the frame's current size. The frame is `tabindex="0"`, `aria-label="Crop area. Arrow keys move it, Shift and arrow keys resize it."`; dragging moves it, dragging a handle resizes it, arrow keys nudge it by 1 px and Shift+arrow keys resize it.
-
-Aspect ratio is a `radiogroup` of five pills — Original, Free, 16:9, 4:3, 1:1 — plus Rotate and Reset actions above it. Width is a second `radiogroup` — Original, 1600 px (default), 1200 px, 800 px. A mono line below reads "Uploads as {width} × {height} px · about {size}", where the estimated size is shown in KB under 1 MB and in MB above it. When the chosen width is larger than the crop's own width, the output stays at the crop's size (never upscaled) and an info row explains why: "The crop is {crop width} px wide, so it's uploaded at that size. Enlarging it would make it blurry." The footer becomes "Choose another file" (back to the file picker, `data-act="upload-pick"` from `idle`) and "Upload image" (starts the upload with the cropped, resized file). SVGs never see this step: they upload as soon as they're chosen. The "in progress" state afterwards reports the resized file's size, e.g. "Uploading 180 of 420 KB".
-
-Validation Before uploading, the uploader checks both the MIME type and the file extension, and that size ≤ 10 × 1024 × 1024 . The size error names the file size: "north-wall.tif is 14.2 MB. Images can be up to 10 MB." A server 400 shows the same message as a client-side rejection.
-
-Props, emits articleId: number . Emits uploaded(location) , close . A 401 hands off to the global session flow. A 404 means the article was deleted, which the editor handles.
-
-A11y, touch The drop zone is a labeled button, so Enter opens the file picker. Progress is exposed as role="progressbar" with aria-valuenow , and the result is announced. On touch screens the drop text is hidden and "Choose file" becomes the main action. Dropping a file directly onto the editor surface also opens the uploader with that file.

-### CodeBlock and EndpointCard
-
-GET /v1/article/{id}
-
-Returns one article. Drafts return 404 to anonymous callers, the same as an id that doesn't exist.
-
-fetch curl Response
-
-JavaScript Copied
-
-const res = await fetch( 'https://cms.renew.example/v1/article/12' )
-
-if (res.status === 404 ) return notFound()
-
-const article = await res.json()
-
-CodeBlock This is a custom component, because Nuxt UI's prose code blocks rely on Nuxt Content and don't work in a plain Vue app. Highlighting is done ahead of time with shiki (a dual github-light / github-dark theme remapped to the semantic colors: keywords info, strings success, numbers warning, comments muted). The header shows the language label and a ghost copy UButton , which switches to "Copied" for 2 s through useClipboard . Props code , lang , label? . Long lines scroll horizontally and never wrap.
-
-EndpointCard UCard › a method UBadge (GET is solid ink) + the path in mono + a description, with UTabs (fetch, curl, Response) showing a CodeBlock each. Props method , path , description , examples: { fetch, curl, response } . Snippets use the current location.origin .
-
-A11y The copy button is named "Copy JavaScript example", and its result is announced. Code is a focusable pre ( tabindex="0" ) so keyboard users can scroll it. Syntax colors pass 4.5:1 on --ui-bg-elevated in both themes.

-
-Built from A custom ul in the password UFormField 's #help slot. Props rules: { label: string, met: boolean }[] , showErrors: boolean . There is no meter or score, because the API only requires 8 characters.
-
-A11y The list is the field's aria-describedby . Each item has hidden text reading "met" or "not met". A change is announced once, when the rule becomes met.

-Built from A custom component that fills AuthShell's slot: an icon tile, h1 title, description and UButton block size="lg" actions. Props tone: 'success' | 'error' | 'info' , icon , title , description , actions: ButtonProps[] . Slot default for extras such as the inline login on verify.
-
-A11y When the panel replaces a form, focus moves to its title and the panel is role="status" , or role="alert" for errors. The countdown updates every second visually but is announced only at the start and when it reaches zero.

-### Error pages and offline banner
-
-You're offline. You can keep writing, but saving and publishing will wait until you're back online.
-
-404 Page not found The link may be mistyped, or the page may have moved. Go to Home All articles
-
-Error Something went wrong This page couldn't load. Your saved work is safe. Try again, and if it keeps happening, restart the RenewCMS server. Try again Go to Home
-
-Built from UError isn't used because it's built for Nuxt's error.vue . Instead there's a custom ErrorView (props kind: 'not-found' | 'error' ), rendered inside UDashboardPanel when the user is logged in and inside AuthShell otherwise. The offline banner is a UBanner color="neutral" at --z-banner , shown and hidden with useOnline() . Once the connection returns it switches to "You're back online" for 3 s.
-
-A11y The error title is the page h1 and gets focus on render. The banner is role="status" , and it can't be dismissed while offline. The offline state blocks Save and Publish and says why in their tooltip.
-
-## Added with the Users and Profile screens
-
-The Product components board was not regenerated for these. They are written from `source/RenewCMS Screens Back-office.dc.html`, `source/AppFrame.dc.html` and the Prototype. Their exact values come from AppFrame.
-
-### UserMenu (changed)
-
-The chip at the foot of the sidebar no longer logs out on click. It opens the account menu, which lists Profile and Log out.
-
-- **Chip:** 40 px high, an initials avatar (26 px, sand `#d4c5b0` with ink text), the name, and a chevrons-up-down icon. `aria-haspopup="menu"`, `aria-expanded`, title "Account". While the menu is open, or while `/profile` is the current page, it takes `--rc-sand` with `#111111` text.
-- **Name:** the display name when there is one, otherwise the username. Initials come from the first letters of the first two words of the display name, uppercased. Without a display name they come from the username.
-- **Desktop menu:** a 224 px popover anchored above the chip on its left edge, with `--rc-shadow-pop`. Header: the name in semibold, the email below it in muted 12 px, a bottom border. Items are 32 px: Profile (circle-user), a separator, Log out (log-out). The current page's item is highlighted with `--ui-bg-elevated`.
-- **Mobile:** the account row in the navigation drawer opens a bottom sheet over an `--rc-overlay` scrim, with a grab handle. Header: 36 px avatar, name in 15 px semibold, email in muted text. Items are 48 px at 15 px text.
-- **Keyboard:** Escape or a click outside closes it. Arrow keys move between items.
-- **Open question:** the shipped menu also offers System, Light and Dark. The board omits them. See [profile.md](screens/profile.md).
-
-### DashboardShell (changed)
-
-The navigation gains **Users** (users icon) between Articles and Integration, in the sidebar and in the mobile drawer. Breadcrumbs for the new pages are "Users" and "Profile".
-
-### UsersTable, UserCardList
-
-Columns Username, Invite status, Created (sorted descending, with an arrow-down icon on the header). Grid `minmax(0,1fr) 160px 160px`, 36 px header on `--ui-bg-elevated`, 44 px rows with a top border. Below md the same rows become cards with a 68 px minimum height: the name line, then the badge and "Created {date}". There are no row actions.
-
-A row's name cell shows the display name first (medium weight, highlighted), the username beside it in muted text, and a mono "you" tag on the current user's row. Invite rows show the email, regular weight, toned. The row of a just-sent invite has `--ui-bg-elevated`.
-
-Skeleton rows appear after 150 ms of loading.
-
-### InviteStatusBadge
-
-A 22 px outline-less badge with a 12 px icon and the word, so status is never shown by color alone.
-
-| Status | Icon | Fill and text |
+Frames: `AppFrame.dc.html` (shell: sidebar, topbar, mobile nav drawer, modal, toasts, articles, editor, users, settings, profile), `ActivityFrame`, `MediaFrame`, `VariantsFrame` (page bodies only), `IntegrationPage`, `IntegrationImages`, `ApiKeysPage`, `CodeSnippet`, `StatesMatrix`. The page-body frames mount inside AppFrame through two props (`slotBody`, `slotOverlays`) so there is one sidebar, one topbar and one drawer.
+
+## Overlay pattern (one rule, applies everywhere)
+| Kind | Desktop | Mobile (390) | Use |
+|---|---|---|---|
+| Dialog | Centered horizontally, 140 px from the top, width 460 (560 wide forms, 640 crop), `--rc-shadow-modal` | Bottom sheet: full width, flush to the bottom, grabber (36×4, `--ui-border-accented`) | Confirmations and forms with up to about four fields |
+| Slide-over | Right panel, full height, over a scrim (Variant form 960 wide with live preview, Media detail, Activity details 480) | Tall bottom sheet, 92% height, grabber, close ×, sticky footer. Never a full page | Only forms with a live preview, and record details. Nothing else may be a slide-over |
+| Menu | Popover under the trigger | Bottom sheet with a title and a close × | Action lists (Export, row menus on mobile) |
+
+Dialog anatomy: header (title 16/24 weight 600, optional description in `--ui-text-muted`, close × 28 px desktop / 44 px mobile), body (padding 20 24 0, gap 16), footer (padding 20 24). Footer order: secondary on the left, primary on the right, aligned right. On mobile the buttons stack with the primary on top, 44 px high. Destructive confirms use `--ui-error` fill with `--ui-bg` text and the verb of the action ("Delete image", "Revoke key"). The scrim is `--rc-overlay`. Esc, the scrim and swipe close unless an action is in flight. In flight, the primary shows `loader-circle` and the verb in -ing form; Cancel is disabled; the dialog cannot be dismissed. Focus is trapped and returns to the trigger.
+Cancel is replaced by an explicit label where "Cancel" would read as the action: "Keep invite", "Keep key", "Restart later".
+Redrawn to this pattern in pass 2: variant form (mobile full page became a sheet), Activity export dialog (was centered, with a header bar and a 480 wide box), API keys dialogs (bordered box, 18 px title, 44 px buttons, 120 px offset), all Media and Variants dialogs (mobile floated with a 16 px inset; now flush sheet with grabber).
+
+## Unified in pass 2
+- Sidebar: ActivityFrame, MediaFrame and VariantsFrame each had their own copy (VariantsFrame's with the Settings group, MediaFrame's with a raw colour). Removed. AppFrame's is the only one. Prototype's own mobile drawer was replaced by AppFrame's drawer (`s.drawer`).
+- Topbar (breadcrumb on desktop, title and lead button on mobile): three copies removed; AppFrame's is used.
+- Mobile nav drawer: VariantsFrame's drawer removed; AppFrame renders one (with the Settings > Media group).
+- Code block: Integration endpoints, Authentication example, error response, API keys (one-time key), base URL field and the image URL builder all use `CodeSnippet`.
+- Modal geometry: AppFrame, MediaFrame, VariantsFrame, ActivityFrame (export) and ApiKeysPage now draw the same dialog and sheet.
+- Toast width: 356 px desktop everywhere (was 356, 360, 372).
+Still separate implementations that look the same (not merged in code, see README "Not done"): toast (5 copies), badge (`Bd` in MediaFrame and VariantsFrame), empty state (MediaFrame and VariantsFrame), modal shell (AppFrame template and the JS shells).
+
+## CodeSnippet
+One component for every code or copyable value. Props: `tabs` (`{ k, label, code }[]`), `active`, `copied`. A header row (min 44 px) holds the tabs and the Copy button; selected tab has a 2 px `--ui-primary` underline and `--ui-text-highlighted` text. With one tab the label is plain muted text (no tab). Copy reads "Copy", then "Copied" with `check` for 2 s (`--ui-success`), announced politely. Body is `pre`, IBM Plex Mono 12/19, scrolls horizontally, `tabindex="0"`. No syntax colouring. Background `--ui-bg-elevated`, border `--ui-border`.
+
+## Editor: link
+- **Toolbar button** (icon `link`, after the list buttons): default `--ui-text-toned`; hover `--ui-bg-elevated` with tooltip "Insert link (Ctrl+K)" (macOS: "Insert link (⌘K)"); focus-visible 2 px `--ui-primary` outline; active when the cursor is inside a link (`aria-pressed`, `--rc-sand` and `--rc-on-sand`); disabled at 40% opacity when an image is selected. 28 px desktop, 40 px mobile.
+- **LinkModal**: dialog on desktop, bottom sheet on mobile. Fields "Link text" (prefilled from the selection), "URL" (http, https, mailto, relative path, #anchor), toggle "Open in new tab". Footer: Cancel left, "Insert link" or "Save link" right; "Remove link" as a text button in edit mode. Errors: "Enter the link text." and "Enter a valid URL. Use http(s), mailto, a path or #anchor."
+- **Link popover** (desktop): under the link, 288 px, URL in mono on top, then "Edit", "Open", "Remove" (error colour). Opens on click or Enter on a focused link; Esc closes. **Touch**: bottom sheet with the link text, the URL and three 48 px rows "Edit link", "Open link", "Remove link". Remove needs no confirmation (undo restores).
+- **Rendered link**: `--ui-text-highlighted`, 1 px underline, 3 px offset. Hover 2 px underline. Focus 2 px `--ui-primary` outline, offset 2. Selected: `--rc-sand` fill, `--rc-on-sand` text.
+- **Toolbar at 390 px**: the full toolbar (22 buttons) does not fit. It scrolls sideways in one row, never wraps; a 24 px fade (`--ui-bg` to transparent) marks hidden content on each side. Buttons stay 40 px.
+
+## Paginator
+First, previous, page numbers, next, last; "Showing 26–50 of 312"; page-size select "5 per page", "25 per page", "50 per page", "100 per page" (default 25). Mobile: previous, "Page 2 of 13", next. Hidden when there is one page. Desktop layout, one row: the summary on the left (it takes the free space), the page-size select next to it, the page controls right-aligned; Sites, Authors, Articles and Media draw it the same way. Buttons 32 px (44 px mobile), current page `--rc-sand` with `--ui-primary` border, disabled controls 40% opacity, focus ring 2 px `--ui-primary`. Page size and page live in the URL as `size` and `page`.
+
+Variant for Sites and Authors (no new component): when everything fits on one page the page-size select is hidden together with the controls and the footer shows only the count line "N sites" or "N authors" in `--ui-text-muted`. Loading dims the whole pager to 40% and disables it; the summary reads "Loading page N…". Sizes are unchanged: 5, 25, 50, 100.
+
+## Activity export
+Menu: "Export current view" (CSV, active filters, all pages) and "Export all activity…" (CSV, ignores filters; owner and admin only). Dialog: Format (read-only "CSV"; a CSV and JSON control appears when JSON ships, proposed), Date range (default "All time"). States: configure, "Preparing download…" (indeterminate bar, no percentage, Cancel left, "Preparing…" disabled right), "Download started" (Close), "Couldn't prepare the download" (Cancel, Retry), "Nothing to export" (Close), 403 "You can't export all activity" (Close). Synchronous: no job, no progress, no later notification.
+
+## FilterCardToggle
+Button with `aria-pressed`; pressed uses `--rc-sand` and `--rc-on-sand` with a `--ui-primary` border; pressing again clears. Synced with the Outcome segment and the chip.
+
+## NavItem and NavGroup
+Row 32 px (44 px in the mobile drawer). Parent selected: `--rc-sand`, `--rc-on-sand`, weight 500. Child selected: parent unfilled, `--ui-text-highlighted`, weight 500, chevron-down; child filled as above. Group label "Media" 11 px uppercase `--ui-text-muted`. Children indent 19 px with a 1 px `--ui-border` rail.
+
+## Media badges (Media library, picker, Variants board)
+`Unused` (warning soft, icon unlink), `Used in N` (outline), `Duplicate` (info soft, icon copy), `N variants` (info soft, icon layers; "1 variant"; none shown at 0). The Media grid card, the list row and the mobile row show all of them. Size column and "Size" meta use the original file size only; the "with variants" size and the sort are on the Variants board (see README, Not done).
+
+## Other
+- **PurgeDuplicatesDialog**: `UModal`, `sm:max-w-md`, sheet on mobile, cancel first, confirm `color="error"`. Props `open`, `preview`, `status` (loading, ready, purging, nothing, error, partial, conflict). Emits `purged`.
+- **MediaCleanupCard**: square `USwitch`, `UInputNumber` with "days" suffix, saves on change.
+- **MediaLinksCard**: rows "Manage image variants" and "Cache usage", 44 px min height.
+- **StatesMatrix**: the board "States matrix: controls".
+
+## Sites and authors (pass 3)
+
+Frames: `DirectoryFrame.dc.html` (Sites, Authors, editor section content; the list, slide-over, delete-with-reassign dialog, slug field and media field are defined once there and used by both Sites and Authors); `AppFrame.dc.html` changed in place (sidebar items, Articles columns and filter, editor section and mobile details sheet, Settings card, Profile card, role-based sidebar). Existing components are reused unchanged: dialogs, toasts, empty states, skeletons, paginator, media picker.

+## Custom content types (pass 4)
+
+Frames: `SchemaFrame.dc.html` (all schema, content and entry bodies; relation, permissions and import frames are Later), mounted in `AppFrame.dc.html`. Existing pieces are reused unchanged: dialogs and sheets, toasts, alerts, paginator, skeletons, empty states, SlugField, CodeSnippet, the single switch.
+
+**AppFrame changes.** Sidebar: a "Schema" item (icon shapes) after Users, owner and admin only. A "Content" group under the main items, one row per custom type (default icon files, name truncated with the full name in the tooltip, selected row sand). Over 5 types it shows the first 5 and the selected one, then "Show all N". Mobile drawer: the group is one collapsed row "All content types" with the count; expanded it lists the types at 44 px. New props on the shell state: `content` (types), `contentOn`, `contentOpen`. The group is hidden when there are no custom types. No existing item changed.

-| Pending | mail | `--rc-warning-soft`, `--ui-warning` |
-| Expired | clock-alert | transparent, `--ui-text-muted`, border `--ui-border-accented` |
-
-### InviteUserModal
-
-A UModal with one field, following the NewArticleModal pattern: title "Invite a user", the text "We'll email them a link to choose a username and password. The link expires after 3 days.", an Email field (placeholder "name@example.com", focused on open), Cancel and "Send invite". While sending, the field is disabled, the button reads "Sending…" and the dialog can't be dismissed. A field error shows under the input, a request failure shows an alert above the buttons, and the address always stays in the field. On success it closes and emits the new invite.
-
-### ProfileCard
-
-A bordered card with 20 px padding (16 px on mobile), a semibold 14 px title, a muted description, and its content. An optional footer strip sits below a top border on `--ui-bg-muted`, with the status text on the left and the action on the right. The Display name card uses the footer; Account and Password do not.
-
-The Display name field uses CharacterCounter with a maximum of 60, counted in Unicode characters, in the mono style on the right of the help row. Read-only fields (username, email, password) are disabled inputs on `--ui-bg-elevated` with a lock icon at the right.
-
-## Themed primitives
-
-Extracted from `source/RenewCMS Components Primitives.dc.html`.
-
-## Components: themed primitives
-
-These are Nuxt UI components with the Ledger config applied. Every specimen reads the real --ui-* variables, so the theme switch on the right changes the whole page. The product components are on a second page .
-
-### Button
-
-There are five roles. A screen gets one primary button. Danger is used only for irreversible actions, and always inside a confirmation step.

-Nuxt UI UButton . Primary color="primary" variant="solid" · secondary color="neutral" variant="outline" · ghost color="neutral" variant="ghost" · danger color="error" variant="solid" · icon-only square icon="i-lucide-ellipsis" :aria-label wrapped in UTooltip .
-
-Loading :loading swaps the leading icon for i-lucide-loader-circle and disables the button. The label changes to the -ing form ("Publishing…") and the button width stays fixed, so the layout doesn't jump. loading-auto is used on async @click handlers.
-
-Keyboard, ARIA Native <button> , activated with Enter or Space. Icon-only buttons need an aria-label . Loading sets aria-busy="true" . Disabled buttons stay focusable only when a tooltip explains why they're disabled.
-
-Responsive md on desktop, xl (44 px) below md . Primary page actions go full width in sticky footers on 390 px screens.
-
-Bend Disabled opacity is 40% instead of Nuxt UI's 75%, because a 75% black button still looks clickable. Hover darkens the button one step instead of using Nuxt UI's /75 alpha, so the label keeps its contrast.
-
-### Input, password input, textarea
-
-One outline style for every field. Focus adds a 2 px ink ring inside the edge. Errors turn the edge brick red and always come with a message, never color alone.

-
-A short first paragraph. You can keep writing in the editor. textarea, autoresize 3–8 rows
-
-Nuxt UI UInput variant="outline" color="primary" , :highlight bound to the field error so the edge turns red. The search field is icon="i-lucide-search" with a #trailing clear UButton . UTextarea autoresize :rows="3" :maxrows="8" .
-
-Password UInput :type="shown ? 'text' : 'password'" with a #trailing ghost UButton . aria-label reads "Show password" or "Hide password", with aria-pressed and aria-controls . autocomplete is current-password on log in and new-password on register and reset. Showing the password never clears or moves focus.
-
-States Default, hover (edge goes to muted), focus (2 px ink), filled, error, disabled, read-only (same look as disabled but selectable and focusable, used for the email on the reset screen). Fields are 16 px text below md .
-
-Placeholder Placeholders use --ui-text-muted (5.7:1) and only show an example. The label always carries the meaning.
-
-### Form field
-
-A label on top, then the control, then the help text or the error in the same spot. The right-hand hint slot holds the character counter. Every field in the product is required, so none are marked.
-
-Username 5 / 20
-
-marta 3 to 20 characters. You'll use it to log in.
-
-Username 2 / 20
-
-ma Use at least 3 characters.
-
-Email marta@renew Enter a full email address, like name@example.com.
-
-Nuxt UI UForm :schema :state @submit + UFormField name label help , with the counter in the #hint slot. Validation runs on blur and on submit, then on every input once a field has an error, so the error clears as soon as it's fixed. The schema mirrors the API rules exactly, so a validator 400 shouldn't reach the UI.
-
-ARIA Nuxt UI links the label and aria-describedby (help or error) and sets aria-invalid . On a failed submit, focus moves to the first invalid field. Error text sits in the help slot, so there is no layout shift.
-
-### Checkbox, switch, select
-
-All three are square. The Preview toggle in the editor is the only switch. The select sets sort order in the mobile article list. No screen needs a checkbox yet, but it's themed so it matches if one gets added.

-
-Keyboard Space toggles a checkbox or switch. The select opens with Enter, Space or ↓, moves with the arrow keys and type-ahead, and closes with Esc, returning focus to the trigger. The switch uses role="switch" and aria-checked , and its visible label is its name.
-
-### Badge
-
-Badges show status or a count. They never replace a button. Solid ink is for the one state that matters most in a list. Soft semantic badges are for system messages.

-
-Nuxt UI UBadge . Solid ink color="neutral" variant="solid" · outline color="neutral" variant="outline" · count color="neutral" variant="soft" size="sm" · semantic variant="soft" . Sizes are sm (22 px, in tables) and md (26 px, in the editor header).
-
-ARIA Badges are text, not live regions. When a status changes, the announcement comes from the toast.
-
-### Alert
-
-Alerts are for messages that belong to a page and stay until the situation changes. Anything that confirms an action someone just took is a toast instead.
-
-Your session expired Log in again to pick up where you left off.
-
-Password changed Log in with your new password.
-
-Almost at the length limit 9 240 of 10 000 characters used. Images and formatting count too.
-
-Couldn't load your articles Check your connection and try again.
-
-Try again
-
-Nuxt UI UAlert variant="soft" :color :icon :title :description :actions . close only on alerts that are safe to dismiss (password changed, session expired). The error alert has no close button because its retry is the way out.
-
-ARIA Info, success and warning use role="status" and error uses role="alert" . Alerts that are already there when the page loads aren't announced again. The description text uses --ui-text-toned rather than the semantic color, so long text stays readable.
-
-### Toast
-
-Toasts confirm that an action finished or failed. Each one has a short title and, at most, one action.
-
-Article published "Winter checklist for timber windows" is now online.
-
-That article no longer exists It was deleted somewhere else, so we removed it from the list.
-
-Couldn't unpublish The server didn't respond.
-
-Retry
-
-Placement Bottom right on desktop, 24 px from the edges. Bottom center at full width minus 16 px on mobile, above the sticky action bar.
-
-Duration Success and info close after 5 s. Errors with retry stay until dismissed or retried. The timer pauses on hover and on focus.
-
-Stack At most 3 visible, newest at the bottom. A fourth pushes out the oldest non-error toast. Repeating the same action replaces its toast instead of adding a new one.
-
-Nuxt UI UApp :toaster="{ position: 'bottom-right', duration: 5000, max: 3 }" . Toasts are raised with useToast().add({ id, title, description, color, icon, actions, duration }) , where id is the action plus the article id so a repeat replaces the old toast. Errors use duration: 0 . The progress bar is off.
-
-ARIA The Reka toast region announces politely, and errors assertively. F8 jumps to the region. Esc closes the focused toast.
-
-### Modal and slideover
-
-Modals ask a question or hold a short form. Slideovers carry navigation and side panels on small screens. Both sit over a 40% ink overlay.
-
-Leave without saving? You have changes to "How we price a bathroom renovation" that haven't been saved.

-
-Nuxt UI UModal :title :description with the #footer slot for actions, width sm:max-w-md . Opened programmatically with useOverlay().create(ConfirmDialog) . USlideover side="right" for details, side="left" for mobile navigation (built into UDashboardSidebar ).
-
-Button order The safe action is primary and sits on the right, where the eye lands. In destructive confirmations, the danger button is on the right and Cancel on the left (see ConfirmDialog). On mobile the buttons stack full width, with the primary on top.
-
-Keyboard, ARIA Focus is trapped and starts on the least destructive button. Esc and the overlay close it unless it's :dismissible="false" , which is used while an action is running. Focus returns to the trigger. The title is the aria-labelledby and the description is the aria-describedby .
-
-Responsive Below sm , modals sit 16 px from the screen edges and slideovers take the full width. Motion follows the foundations: 240 ms, and instant with reduced motion.
-
-### Dropdown menu and tooltip
-
-The row-action menu is the main dropdown. Delete always comes last, below a separator, in brick red. Tooltips name icon-only buttons and show their keyboard shortcut.
-
-Edit
-
-Unpublish
-
-Copy API URL
-
-Delete…
-
-Bold Ctrl B
-
-Nuxt UI UDropdownMenu :items :content="{ align: 'end' }" , with items grouped in nested arrays so separators appear automatically. The Delete item is color: 'error' , and its label ends in "…" because it opens a confirmation. UTooltip :text :kbds="['ctrl', 'b']" :delay-duration="400" .
-
-Keyboard The menu opens with Enter, Space or ↓. Arrow keys and type-ahead move through it, Home and End jump to the ends, and Esc closes it and returns focus. Tooltips appear on focus as well as hover and never hold information that isn't also in the aria-label .
-
-Touch Tooltips don't show on touch, so every icon-only control on mobile also appears in a labeled menu or has a visible label.
-
-### Tabs
-
-Tabs filter the article list. Each count comes from the full list, so it doesn't change while you search.
-
-All 6
-
-Online 4
-
-Drafts 2
-
-Focused
-
-From left: selected, default, hover, focus-visible.
-
-Nuxt UI UTabs variant="link" color="neutral" :content="false" :items v-model . The count goes in the #trailing slot as the mono sm count badge. The value syncs to ?status=online|draft so the filtered view can be linked.
-
-Keyboard Roving tabindex: Tab enters the tab list on the selected tab, and ← and → move and activate. Each tab's accessible name includes its count, for example "Drafts, 2 articles".
-
-Responsive Tabs stay in one row at 360 px, which is why the labels are short. Each tab is 44 px tall on touch.
-
-### Table and pagination
-
-Rows are 44 px with hairline separators, and only the Updated column sorts. Pagination appears only when a filter shows more than 25 articles.

-States Default, hover ( bg-elevated ), focus-visible (2 px inset ring), busy (a row action is running: 50% opacity, a spinner in the status cell, aria-busy , actions disabled), loading (skeleton rows), empty (EmptyState in the #empty slot).
-
-Keyboard, ARIA Each row's title is a real link to the editor, so Tab reaches it and Enter opens it. The rest of the row is a click target for the mouse only. The sort header is a button with aria-sort . Pagination is a nav labeled "Pages", and the current page has aria-current .

-Skeleton USkeleton blocks shaped like the real layout: the same row heights, a badge-sized block and a date-sized block. The pulse runs at 1.6 s and stops with reduced motion. The container is aria-busy="true" and a visually hidden live region says "Loading articles". Skeletons appear only after 150 ms, so fast responses never flash.
-
-Avatar UAvatar :alt="username" size="xs|sm" . The initials come from the username: split on anything that isn't a letter or digit, take the first letter of the first two parts, or the first two letters if there is only one part, then uppercase. Sand #d4c5b0 with ink text (11.2:1) in both themes. It's decorative ( aria-hidden ) because the username is always shown next to it.
-
-Kbd UKbd variant="outline" , only inside tooltips and the editor's shortcut hints. The editor shortcuts are Ctrl/⌘ S to save, plus TipTap's defaults: B, I, U, Z and Shift Z.
-
-Separator USeparator uses --ui-border by default and --ui-border-accented between groups in dense toolbars. It's decorative, with role="none" , except between menu groups.
-
-### Color mode
-
-Three choices: System (the default), Light and Dark. The toggle at the top of this page is the component itself, so you can try it.
-
-Nuxt UI In the user menu: a UDropdownMenu group of three type: 'checkbox' items bound to useColorMode().preference . On auth screens: UColorModeSelect in the footer. Nuxt UI's UColorModeButton isn't used because it only toggles between light and dark and hides the system option. colorMode: true in the plugin handles storage and applying the .dark class before first paint.
-
-ARIA Menu items use menuitemcheckbox , with aria-checked on the current choice. The segmented variant is a radiogroup named "Theme".
+| ScopeControl (tri-state) | None / Own / All in grid cells, mobile cards and general rows | URadioGroup variant="table" orientation="horizontal" size="xs", three items, in a grid cell. Selected item: sand fill, weight 600 and an underline |
+| OnOffCell | Create column and boolean rows | USwitch with visible On/Off label |

+| ReadOnlyBanner | Read-only pages | UAlert color="info" icon="i-lucide-lock" variant="soft" |
+| ViewOnlyMark | Own scope rows | Text with lucide lock icon and UTooltip |
+
+Accessibility of the tri-state cell:
+| Item | Pattern |
+|---|---|
+| Structure | The grid is role="grid". Each cell contains a role="radiogroup" named "{Type}: {Action}" (for example "Events: Update") with three role="radio" items None, Own, All. Create is a role="switch" named "Events: Create". |
+| Keyboard | Tab moves between cells (one stop per cell). Inside a group, Left and Right (or Up and Down) move and select, Home and End jump to None and All. Arrow keys also move the roving tabindex. Space selects. Header bulk buttons open a menu with the same three values. |
+| Announcement | Selected item is aria-checked="true". A polite live region announces changes: "Events, Update, set to Own." Disabled items are aria-disabled and described by the reason ("You can only grant what your role has."). |
+| Not by color alone | Selected segment: sand fill plus weight 600 plus a 2 px underline in --ui-primary. Locked: lock icon. Changed cell: square marker. Mixed: text badge. |
+| Targets | 26 px segments on desktop, 44 px on mobile. Focus: 2 px --ui-primary outline, offset 2 px. |

 # Foundations
 
-Token source files (copy them into `web/src/theme/` in the Nuxt UI foundation slice, which then becomes the live source):
-
-- `source/tokens/renewcms.css`: `@theme`, `:root`, `.dark` and the `.article-content` scale
-- `source/tokens/ui.config.ts`: Nuxt UI color aliases, icons and component `ui` overrides
-- `source/tokens/vite.config.ts`: the `@nuxt/ui/vite` plugin setup
-- `source/tokens/tokens.json`: the same values as data
-- `source/brand/favicon.svg`: the mark, dark-aware
-
-Extracted from `source/RenewCMS Foundations.dc.html`:
-
-## Ledger foundations
-
-Everything below is generated from one set of files: tokens/renewcms.css (Tailwind @theme , :root , .dark , article content styles), tokens/ui.config.ts (Nuxt UI colors, icons and component overrides) and tokens/vite.config.ts . The tables on this page read those files, so they can't drift.
-
-### Logo
-
-The mark is a white R on a black square, drawn on a 16-pixel grid so it stays sharp as a favicon. It keeps the same geometry at every size. In dark mode the black square gets a 1 px #444 edge so it doesn't disappear into the background. The wordmark pairs the mark with RenewCMS in Plex Sans Semibold, with the text set at 0.6× the mark's height.

-Favicon file: brand/favicon.svg . The 1 px edge switches on with prefers-color-scheme: dark . Keep clear space of at least half the mark's height around it. The R is never recolored or placed on sand.
-
-### Color scales
-
-Seven Tailwind color scales, each mapped to a Nuxt UI alias. The ink, chalk and sand scales are built on your brand values. The four semantic scales are new and deliberately muted: evenly spaced oklch lightness steps with low chroma, so they sit comfortably next to ink and sand.
-
-### Theme variables
-
-Every --ui-* variable Nuxt UI reads, for both themes. Surfaces are white. The #fafafa brand background is the page canvas behind them. The theme follows the system setting until the owner picks Light or Dark from the user menu, and that choice is stored by Nuxt UI's color mode.
-
-Variable Used for Light Dark
-
-### Contrast checks
-
-Pair Needs Light Dark
-
-### Typography
-
-The interface uses IBM Plex Sans in three weights: 400, 500 and 600. IDs, paths, counters and code are set in IBM Plex Mono. Sizes replace Tailwind's text-* defaults. On screens narrower than md , form fields use 16 px so iOS doesn't zoom in when a field gets focus.
-
-Before and after: the Rue Verte kitchen
-
-GET /v1/article/12 · 8 412 / 10 000
-
-font-mono · 13px / 20px · 400 Code, paths, IDs, counters
-
-Article content uses a separate scale in Source Serif 4, applied through the .article-content class. The editor surface and the preview both use it, so what the owner writes looks like what a public site would roughly show. The measure is capped at 42 rem, about 70 characters per line.
-
-Choosing lime plaster for old stone walls
-
-Cement traps moisture in solid walls. Lime lets the stone breathe, which is why we strip it back on almost every farmhouse we take on .
-
-What we use
-
-Hot-mixed lime for the base coat
-
-Hair or fibre for the scratch coat
-
-A thin lime putty finish
-
-Drying time
-
-It sets slowly, and that is the point.
-
-Before you start
-
-Strip loose material back to sound stone.
-
-Wet the wall the evening before.

-The north wall after the second coat.
-
-Element md and up Below md, spacing
-
-### Spacing, radius and density
-
-Spacing uses Tailwind's 4 px base unit unchanged. Radius is 0 everywhere: setting --ui-radius: 0rem flattens every component that derives its corners from it, and rounded-none overrides cover the few that hard-code rounded-full . The density is compact on desktop. On touch screens, every tap target is at least 44 px.

-### Icons
-
-Lucide through Iconify, using Nuxt UI's i-lucide-* classes. Icons are 16 px next to 13–14 px text and 20 px on mobile top bars. They are always paired with a visible label or an aria-label . Each icon maps to one meaning: Eye is only ever show password, and Preview uses Book Open.

-### Where Nuxt UI defaults bend
-
-### Files
-
-Ready to paste into the repository. They follow its code style: tabs, no semicolons, single quotes and no comments. The CSS goes in src/assets/main.css and the config in src/theme/ui.config.ts . Add class="isolate" to the app root, as Nuxt UI requires.
+Tokens only. No raw hex or rgb in any frame. The one exception is the brand mark SVG (`#111` and `#fff` fills). Radius is 0 everywhere (no `border-radius` is declared in any frame).
+
+## New tokens (do not exist in the app yet)
+`tokens/renewcms.css` defines no `--rc-*` token. The frames use the ones below. They are **new**. Add them to the app's CSS, light values in `:root` and dark values in `.dark`. No `--ui-*` token is changed.
+
+| Name | Light | Dark | Used by |
+|---|---|---|---|
+| `--rc-sand` | #e8dfd1 | #d4c5b0 | Selected nav item (parent and child), selected table row and media card, current paginator page, pressed filter card, avatars, account chip, "In this article" tag, drag-drop fill |
+| `--rc-on-sand` | #111111 | #111111 | Text and icons on `--rc-sand`. Never use `--ui-text-muted` or white on sand |
+| `--rc-success-soft` | #eaefea | #1f241f | Success badge, success alert and toast icon ground |
+| `--rc-info-soft` | #ebeef0 | #202428 | Info badge, info alert, "variants" badge, duplicate badge |
+| `--rc-warning-soft` | #f0ede6 | #2a251e | Warning badge and alert, "Unused" badge |
+| `--rc-error-soft` | #f3eae9 | #2c201f | Error badge and alert, failed-actions card |
+| `--rc-overlay` | rgb(10 10 10 / 0.4) | rgb(0 0 0 / 0.6) | Dialog, sheet and slide-over scrim; crop mask |

+| `--rc-shadow-modal` | 0 16px 48px rgb(17 17 17 / 0.18) | 0 16px 48px rgb(0 0 0 / 0.6) | Dialogs, sheets, slide-overs. Same as `--shadow-modal` |
+| `--rc-canvas` | #ecebe8 | #1c1c1c | Design boards only. Not for the app |
+
+Implementers may alias `--rc-shadow-pop` and `--rc-shadow-modal` to the existing `--shadow-popover` and `--shadow-modal`. The Nuxt UI `UAlert`/`UBadge` `soft` variants can map to the four `-soft` tokens.
+
+## Contrast (computed, AA: text 4.5:1, UI components 3:1)
+Light | dark. Computed with the WCAG relative luminance formula from the token values above and the `--ui-*` values in the board root.

+| Segmented: selected `--ui-bg` on `--ui-primary`; unselected `--ui-text-toned` on `--ui-bg` | 18.9; 9.7 | 18.1; 11.8 | Pass |
+| Placeholder `--ui-text-muted` on `--ui-bg` | 5.7 | 6.6 | Pass |
+| `--ui-text-muted` on `--rc-sand` | 4.3 | 1.7 | **Fails.** Never place muted text on sand. Frames use `--rc-on-sand` |
+| `--ui-text-dimmed` on `--ui-bg` | 2.8 | 3.3 | **Fails.** Not used for text. Allowed for disabled icons and decorative strokes |
+| Disabled controls at 40% opacity (label on `--ui-bg`) | 2.6 | 3.7 | Exempt (inactive component). Never carry information only in a disabled label |
+| Disabled table row at 55% opacity | not computed | not computed | Exempt (inactive) |

+| UI: `--rc-sand` fill against `--ui-bg` | 1.3 | 11.2 | **Fails in light** as the only indicator |
+| UI: `--ui-border` on `--ui-bg` | 1.3 | 1.5 | Decorative only (card and table lines). Never the only boundary of a control |
+
+Fixes applied (token swaps):
+- Current page in the paginator: border changed from `--rc-sand` to `--ui-primary` (18.9 / 18.1) so the state does not rely on a 1.3:1 fill.
+- Selected media cards and rows keep `--ui-primary` outline with the sand fill (already so).
+- Selected nav items still rely on the sand fill plus weight 500 and `aria-current="page"`. The fill alone is 1.3:1 in light; the weight change and the programmatic state carry the information. This is accepted and recorded here, not "fixed".
+- Rule added: `--ui-text-muted` is never used on `--rc-sand`.
+Not computed: hover and active backgrounds of every control against every text colour; the states-matrix uses combinations already listed above.
+
+## One value per role (spacing, radius, type, icons)
+Sweep of the frames (`AppFrame`, `ActivityFrame`, `MediaFrame`, `VariantsFrame`, `IntegrationPage`, `IntegrationImages`, `ApiKeysPage`, `CodeSnippet`, `AuthCard`). "Found" is what was drawn before pass 2.

+## Pairings
+- Selected rows use `--rc-sand` with `--rc-on-sand` text and icon in both themes. Hover, focus-visible and active on a selected row keep sand. Focus adds a 2 px `--ui-primary` outline.
+- Child selected: the parent row is not filled. It uses `--ui-text-highlighted`, weight 500, chevron down.
+- Focus-visible: 2 px `--ui-primary`, offset 2 px (inset -2 px for tabs, segmented controls and rows).
+- Disabled: 40% opacity (table rows 55%).
+- Hover, active and the rest: board "States matrix: controls" (`StatesMatrix.dc.html`). Hover and active tokens: primary button hover `--ui-text`, active `--ui-text-toned`; secondary and ghost hover `--ui-bg-elevated`, active `--ui-bg-accented`; destructive hover opacity 0.85, active 0.75; input hover border `--ui-text-muted`, focus border `--ui-primary`.

+# Media field type: change list for implementation
+
+Board: `RenewCMS Screens Schema.dc.html`. Frames changed: `SchemaFrame.dc.html`, `MediaFrame.dc.html`. Spec data: `schema-spec.js` (states) and `media-field-tables.js` (tables, appended to the board). No new tokens, no new colors, radius 0.
+
+## 1. Behaviour
+- New field type `media`, name "Media", icon `lucide:image`, description "One image from your media library".
+- Stored value: id of a library image, or null. The file is never copied. The field always shows the current library image.
+- Options: label, key, required. No default, unique, min, max or choices. The inspector hides them.
+- Required: the entry can't be saved while the field is empty (422 invalid_entry, rule required).
+- A saved field's type never changes. Key and type are locked after the first save (existing rule).
+- Adding a required media field to a type with entries is refused, because a media field can't have a default. The review step shows this before the server is asked.
+- Image deleted while entries point at it: the entry keeps the id. The control shows the missing state. Saving is refused only if the field is required.
+- Entries count as uses of an image in Media. Deleting a used image is allowed after a warning.
+- Variants: the editor preview uses the original. No variant select in the field. Nothing about variants in the builder.
+- Galleries (several images) are out of scope and not drawn.
+
+## 2. New component: MediaFieldControl
+Props: label, required, modelValue (image id or null), image (filename, width, height, size, or `missing: true`), disabled, error. Emits `update:modelValue`. Opens the picker.
+Nuxt UI v4: `UFormField` (label, help, error, required), `UButton` outline ("Pick an image", "Change image", "Choose another image"), `UButton` ghost ("Remove", "Clear"), `UModal` on desktop and bottom `UDrawer` on mobile for the picker, `UTooltip` for the list placeholder and the badge, `UIcon` lucide:image, image-off, unlink, image-plus. The thumbnail is a plain `button`.
+
+States and measurements (SchemaFrame `MCtl`):
+| State | Drawing |
+|---|---|
+| Empty | Dashed box (1px dashed `--ui-border-accented`), padding 12, 40 px icon square (`--ui-bg-elevated`), "No image selected.", button "Pick an image" (icon image-plus). Mobile: stacked, 44 px button |
+| Filled | Solid 1px `--ui-border-accented` box, padding 12. Thumbnail 160 × 120 (mobile: full width, 16:9). Filename weight 500, then "1600 × 900 · 240 KB" 12/18 muted. Buttons "Change image" (outline, icon image) and "Remove" (ghost, icon x). Help line "One image from your library." |
+| Hover (desktop) | Border `--ui-text-muted`. Bottom bar 28 px, `--ui-bg-inverted` with `--ui-text-inverted`, icon image 14 and "Change image". No hover on mobile |
+| Focus | 2 px `--ui-primary` outline, offset 2, on the thumbnail button |
+| Error | Box border `--ui-error` plus inset 1px `--ui-error`, error line with circle-alert 14: "Pick an image for Thumbnail." Focus ring on the first button (Pick an image, or Choose another image) |
+| Missing | Dashed 160 × 120 (mobile 16:9) placeholder with image-off 24. Text "This image is no longer in the library" (weight 500). Help: optional "You can still save. The entry keeps the link until you change it." / required "Thumbnail is required. Choose another image to save." Buttons "Choose another image" (outline) and "Clear" (ghost) |
+| Saving | Thumbnail at 60%, buttons at 40%, all form fields disabled, Save reads "Saving…" |
+| Read-only (fields changed) | Same as saving, plus warning alert "The fields of Events changed" and button "Reload form" |
+
+Label is the field label, plus " *" when required (existing form rule; "(optional)" is not used).
+
+## 3. Per screen
+
+### 3.1 Schema list (group 1), state "Custom type: read-only view"
+Fields table of a custom type (Label, Key, Type, Rules) in the built-in table style. Thumbnail row: image icon, key `thumbnail`, type "Media", rules "One image from the library". Header "Events" with badge "Read only" (lock). Alert: "You can read these fields here" / "Only an owner or admin can change a content type." The built-in Media type in Schema is unchanged. Decision needed: no route shows a custom type read-only today.
+
+### 3.2 Schema builder (group 2), 3 states
+- "Media field selected": saved Thumbnail row selected (index 7). Inspector: Label, Key (locked, "Used in the API, so it can't change."), Type tiles (seven, Media selected, others dimmed with "Can't change after saving"), Required switch ("Required" / "An entry can't be saved with this field empty."). Hidden for media: Unique values, Default value, limits, choices. Hint (info-soft block, info icon): "Holds one image from the media library. Entries link to the image instead of keeping a copy, so they always show its current version."
+- "New media field, seven types": new row with "New" badge, key editable ("The name used in the API. Starts with a letter. Lowercase letters, digits and underscores."), type tiles all enabled. State chip "Unsaved changes".
+- "Media field, required": row shows the existing Required marker.
+- Field row: grip, 28 px icon square (image), label, key (mono), badges. Mobile: inspector in the existing 92% sheet (title "Field: Thumbnail", footer "Done").
+- Type tile grid now has seven tiles (3 columns desktop inspector, 2 in sheets).
+
+### 3.3 Review (group 3), 2 states
+Dialog "Review changes to Events" / "Apply them to save the content type." Summary "Add 1 field" / "Events has 12 entries. Each one is checked against the new fields when you apply." The info bar in the builder behind reads "12 entries use this content type…".
+- Refused: row "Add Thumbnail", warning flag "Can't be applied", text "Media, required. A media field can't have a default, so the 12 existing entries would have no image. Make Thumbnail optional to add it." Note "Back to editing keeps your other changes." Buttons "Back to editing", "Apply changes" (disabled). This departs from the existing review (Apply is never disabled): decision.
+- Clean: row "Add Thumbnail", "Media, optional. 12 entries are unaffected." Apply enabled.
+
+### 3.4 Field types (group 4), state "Media"
+Per-type frame like the others: header icon image, "Media", "One image from your media library", `type: "media"`. Columns: inspector options, entry form control (filled with hover, then empty), list cell (Filled thumbnail, Empty "–", Image missing), errors by rule, filter (later).
+Errors by rule: required 422 "Pick an image for Thumbnail."; type 422 "Thumbnail must be an image from the library."; min, max, options, unique: "Not used for media." Filter widget: "Thumbnail: has an image" with Any / Has an image / No image, tagged Later.
+
+### 3.5 Entry list (group 5), 3 states
+Columns shown: Title, Thumbnail, Starts on, Category (user choice). Header "Thumbnail", no sort icon, column 80 px. Cell: 40 px square thumbnail; "–" when empty; dashed 40 px square with unlink icon, accessible name "Image no longer in the library", when the image is gone. Row height stays 48 px (thumbnail fits with 4 px above and below). Mobile card: 32 px thumbnail leads the card (empty: "–", missing: dashed square), card min height 68 px. Columns menu lists Thumbnail with the image icon ("4 of 6", "Choose up to 6 fields to show. 4 selected." on mobile). Tooltip on the missing placeholder (desktop): "Image no longer in the library".
+
+### 3.6 Entry editor (group 6), 10 states
+Control sits after Description, at the end of the form (schema order; see conflicts). States: empty optional, empty required, filled, hover, focus, validation error (status chip "Not saved"), image no longer in the library, missing + required (error), saving, read-only. The board scrolls the form so the control is visible in the frame; the real form is not scrolled.
+
+### 3.7 Picker (group 10), 8 states, MediaFrame field mode
+Existing picker (Upload and Library tabs, single selection, search "Search by filename", "Newest first · 48 images", Load more, 4 columns desktop and 3 on mobile, square tiles). Differences:
+- Title "Choose an image".
+- Primary "Use this image" (disabled until a tile is chosen). When "No image" is chosen it reads "Remove image".
+- No alt text field, no variant select. Selected strip shows thumbnail, filename, "dimensions · size".
+- Current image tile badge "Current" (replaces "In this article").
+- Optional fields only: row "No image" / "Leave this field empty." at the top of the Library tab. Selected: sand fill, primary border, check.
+- Empty: "Your library is empty" / "Images you upload appear here, ready to use in any article or entry." / "Upload an image".
+- Failed: "Couldn't load your library" / "Check your connection and try again." / "Try again".
+- Loading: skeleton tiles after 150 ms.
+- Upload tab: unchanged flow (crop, resize); the new image lands in the library and is selected.
+- Desktop dialog 640 wide, mobile bottom sheet.
+
+### 3.8 Media library (group 11), 4 states
+- Badge "Used in N" = articles + entries. The tooltip (hover or focus) reads "Used in entries: 3" and, if articles also use it, "Used in articles: 2" on the first line. Example: bathroom-tiles.png, 3 entries, "Used in 3".
+- List view: same badge in the list row and mobile card.
+- Detail panel (lime-plaster.jpg, 2 articles, 5 entries): preview is shorter when the image has entries; existing "Used in 2 articles" list; new section "Used in entries" with up to 3 rows (type name muted, entry title as link, arrow-up-right) and "and 2 more". When there are entries the empty-articles line reads "No article shows it." (not "safe to delete").
+- Delete: title "Delete an image that's in use?" (existing in-use dialog), body `"lime-plaster.jpg" is used in 5 entries and 2 articles. Those entry fields will show "This image is no longer in the library", and the articles will show a broken image. This can't be undone.` with the entries and articles lists; "Cancel" and destructive "Delete image".
+
+## 4. Copy added (exact)
+Media · One image from your media library · Holds one image from the media library. Entries link to the image instead of keeping a copy, so they always show its current version. · No image selected. · Pick an image · Change image · Remove · Choose another image · Clear · One image from your library. · This image is no longer in the library · You can still save. The entry keeps the link until you change it. · Thumbnail is required. Choose another image to save. · Pick an image for Thumbnail. · Thumbnail must be an image from the library. · Not used for media. · Image no longer in the library · Choose an image · Use this image · Remove image · Current · No image · Leave this field empty. · Used in entries · and 2 more · Used in entries: 3 · Can't be applied · Media, required. A media field can't have a default, so the 12 existing entries would have no image. Make Thumbnail optional to add it. · Media, optional. 12 entries are unaffected. · The Thumbnail field was changed after you opened this form. Reload the form to continue. What you typed here can't be saved against the old fields.
+Sentence case, "image" never "asset", buttons are verbs.
+
+## 5. API and backend
+- Schema API accepts type `media` with label, key, required. Value: image id or null.
+- 422 invalid_entry: required → "Pick an image for Thumbnail."; type (id not in the library on a changed value) → "Thumbnail must be an image from the library."
+- Entry and list responses include, per media field, filename, width, height, size and a thumbnail URL, or `missing: true`.
+- GET /v1/media/{id}/usage returns articles and entries (content type name, key, entry id, title), a total and the first few items. GET /v1/media/ list items carry the combined use count.
+- DELETE /v1/media/{id} stays allowed for used images. Entries keep the id.
+- A new required media field on a type with entries is refused (schema_incompatible). The client shows the refusal first.
+
+HTTP to copy (picker and field), from states.md: 400 "That request wasn't valid. Check the fields and try again."; 401/403 global; 404 "That item no longer exists."; 409 "This changed somewhere else. Reload and try again."; 413 "That file is too large."; 429 "Too many requests. Try again in a few minutes."; 500/network "Something went wrong on our side. Nothing was changed. Try again in a moment."
+
+## 6. Accessibility
+- Control is `role="group"` labelled by the field label. Required: `aria-required` on the main button.
+- Names: "Pick an image for Thumbnail"; thumbnail "Change image, lime-plaster-workshop.jpg, 1600 by 900, 240 KB"; "Remove image from Thumbnail"; "Clear Thumbnail"; missing placeholder `role="img"` "Image no longer in the library".
+- Error: error text has an id. The main button gets `aria-invalid="true"` and `aria-describedby` (error id, then help id). Focus moves to the first invalid control on a refused save.
+- Order: label, thumbnail, Change image, Remove, help or error. The thumbnail duplicates Change image; use `tabindex="-1"` on it if one stop is preferred.
+- One polite live region: "Image selected: lime-plaster-workshop.jpg", "Image removed from Thumbnail.", "Thumbnail cleared."
+- Focus: Use this image → Change image. Remove or Clear → Pick an image. Cancel or Esc → the opener.
+- Picker: tiles are buttons with `aria-pressed`, names "stone-steps.jpg, 310 KB, Current". "No image" has `aria-pressed`. "Use this image" uses `aria-disabled`.
+- Contrast: Current badge and selected rows use `--rc-on-sand`; hover bar 18.9 (inverted pair). 44 px targets on mobile. No hover on mobile.
+
+## 7. Conflicts to decide
+1. Row height: design is 48 px (56 px media rows, 68 px cards), not 32 px. Drawn at 48 and 68.
+2. Thumbnail position: existing form has Description last. Drawn after Description (end of form).
+3. "Used in N" counted articles. Now articles + entries.
+4. Delete title: existing in-use title kept; "Delete this image?" stays for unused images.
+5. "Clear" vs glossary "Remove".
+6. "1600 × 900 · 240 KB" (design separator) instead of "1600 x 900 - 240 KB".
+7. Review step disables Apply for the certain refusal; existing review never does.
+8. Picker button "Use this image" vs article picker "Insert image"; "Remove image" when No image is chosen is my addition.
+9. "Pick an image" also on optional empty fields.
+10. No read-only route for custom types.
+11. Two tab stops for the same picker (thumbnail and Change image).
+12. Disabled opacity: form 60%, foundations 40%.
+13. The picker frame shows a stand-in entry form, not the real editor.
+
+## 8. Not done
+README.md, states.md and the screens/*.md files are not updated with the new counts (group 2 +3, 3 +2, 4 +1, 5 +3, 6 +10, 1 +1, new groups 10 (8) and 11 (4): 32 states). Light/dark and mobile frames were checked by reading the DOM, not state by state on screen.

+## Pagination in the URL (Articles, Media)
+`/articles?page=2&size=50` and `/media?page=7&size=50`. Parameter names follow the repo (activity already uses `page` and `size`). Allowed sizes 5, 25, 50, 100. Defaults `page=1`, `size=25`, omitted from the URL when default. Changing search, tab, filter or size resets `page` to 1. `page` above the last page redirects (replace) to the last page and shows "That page doesn't exist. Showing the last page." An invalid `size` falls back to 25.
+**API:** `GET /v1/article/` accepts `page` (default 1) and `size` (5, 25, 50, 100; default 25), as `GET /v1/activity` does. The body stays a JSON array so existing consumers keep working; the total comes back in `X-Total-Count` (the response shape is to be confirmed with the specifier). Anonymous callers only see online articles, and the total counts only those. Invalid `page` or `size` answers 400, the same as Activity.
 
-Auth values: `public` needs no session, `session` needs a logged-in account (verified or not), `verified` needs a verified account, `any` applies to redirects and the catch-all.
+**Media API:** `GET /v1/media/` takes the same `page` and `size`, with the same 400 and the total in `X-Total-Count`; the array body stays. The earlier `cursor` and `limit` parameters are replaced by them.
+
+**Page size memory:** the size chosen on Articles, Activity or Media is remembered for the user and used when the URL has no `size`; an explicit `size` in the URL wins.
+
+**SPA:** never shows that 400. A `size` outside 5, 25, 50, 100 or a `page` that is not a positive integer is replaced in the URL by the default (`history.replace`), silently. A `page` past the last page is replaced by the last page and the notice "That page doesn't exist. Showing the last page." appears.
+
+## Activity pagination
+`page` and `size`, allowed sizes 5, 25, 50, 100, default 25 (as implemented).
+
+## Activity export
+`GET /v1/activity/export`: implemented. CSV only, synchronous (one streamed download, no job, no progress, no later notification). Accepts the list filters q, actor, category, outcome, security, range, from, to. Owner and admin only; others get 403. "Export current view" calls it with the active filters. "Export all activity" calls it with no filters and an optional `from`/`to` range. JSON (`format=json`) is **proposed**: new backend feature.
+
+## Public image request
+`/media/photo.png?v=<variant-name>`. Unknown or disabled variant: 400 `{ "status": 400, "error": "unknown_variant", "message": "Unknown variant", "detail": "<name>" }`. Any other query parameter: 400 `{ "status": 400, "error": "unsupported_parameter", "message": "Unsupported parameter", "detail": "<parameter>" }`. Missing source image: 404.
+
+## Sites and authors in the URL
+`/articles?site=journal` filters by site key; it combines with `page`, `size`, `tab` and `q`, and resets `page` to 1 when it changes. An unknown key is dropped from the URL with no error. `/authors?q=camille&page=2&size=25` follows the same pagination rules as Articles. Deep links: `/authors?edit={slug}` and `/settings/sites?edit={key}` open the slide-over for owner and admin (authors) and the owner (sites); an unknown value shows the info toast "That author no longer exists" or "That site no longer exists". For other roles `/authors?edit={slug}` opens the read-only detail, and `/settings/sites` and its `?edit=` link show the 403 page "You don't have access to Sites".
+
+Sites pagination: `/settings/sites?q=&page=&size=` with the same rules as Articles (sizes 5, 25, 50, 100; default 25; defaults omitted; search and size changes reset to page 1; a page past the end falls back to the last page). API: GET /v1/site/?q=&page=&size=, total in `X-Total-Count` (design assumption). Authors: `/authors?q=&page=&size=` as above.
+
+## SEO
+No new page routes. The panel and dialog are overlays on `/article/:id/edit`: `?panel=seo` (optionally `&field=seo_title|seo_description|slug|cover|authors|body` for the suggestion jump) and `?dialog=seo-api`. `/articles?seo=suggestions` is the Needs attention filter. API: GET /v1/article/{id}/seo, GET /v1/site/{key}/sitemap?page=&size=, PATCH /v1/article/{id} (new fields), PATCH /v1/site/{id} {site_name, title_template, default_description, social_image_id, default_robots}, GET /v1/article/?seo=ready|suggestions|hidden. 401 without a session; 403 owner_only on site SEO fields; 409 slug_taken {suggestion} on PATCH slug; 400 on invalid canonical_url or title_template.
+
+## Custom content types in the URL
+`/content/events?page=2&size=50&sort=created_at:desc`. `page` and `size` follow Articles (sizes 5, 25, 50, 100; default 25). `sort` is one parameter, `<id|created_at|updated_at>:<asc|desc>`, default `updated_at:desc`. Defaults are omitted from the URL; a size or sort change resets `page` to 1; invalid values are replaced silently by the default; a `page` past the end falls back to the last page. The response carries `total`, `page`, `size` and `sort`: use them for the summary ("Showing 1–5 of 37"), the pager and the "37 entries use this content type" line of the review step. No filter or search on custom fields yet. Auth: `/schema*` owner or admin (403 page otherwise), `/content*` any verified user (unverified accounts are redirected to /register/pending). Unknown type: 404 content_type_not_found page. Unknown entry: 404 entry_not_found page.

+|---|---|---|

+| /settings/roles/:id | Role editor (read-only without manage) | Roles: view |

+
+An author is a public byline, not an account. It may be linked to one CMS user; guest writers have no link. The slug is globally unique, generated from the name and editable. An article has zero or more authors in a set order; the first is the primary byline. Zero authors is allowed.
+
+**Roles.** Owner and admin can create, edit and delete any author. Other roles see the Authors screen read-only: the list and a read-only detail, with no Add author button, no row menu, no slide-over form and no delete. They can pick authors in the article editor. Any role can use "Create my author profile" and edit their own linked author: the form opens with the linked user locked and has no delete action.
+
+**Shared pieces.** The list, slide-over, delete-with-reassign dialog, slug field and media field are defined once in `DirectoryFrame.dc.html` and referenced by both Authors and Sites. The media picker is drawn once, in "Authors: form". The server-fallback 409 dialog is drawn once, in "Authors: delete".

+
+Route: `/authors?page=3&size=50`. API: GET /v1/author/?q=&page=&size= (total in `X-Total-Count`, array body unchanged; `q` already exists). Owner, admin and read-only roles see the same pager. Drawn with 128 authors (6 pages) and generated rows.
+
+**URL.** `/authors?page=2&size=50`. `page` and `size` are the parameter names (as Articles and Activity). `size` is one of 5, 25, 50, 100; default 25. Defaults are omitted from the URL (`page=1`, `size=25`). Combined with search: `/authors?q=mar&page=2`. A search change or a size change resets `page` to 1 and drops it from the URL. An invalid `size` or `page` (not a positive integer) is replaced silently by the default with `history.replace`. A `page` past the last page falls back to the last page: the URL is replaced by `?page=<last>` and the info notice "That page doesn't exist. Showing the last page." is shown, as on Articles. Browser Back returns to the previous page of results.
+
+**Pager.** The same component as Articles and Media, in the same footer position (below the list, summary on the left, page-size select next to it, right-aligned controls; mobile: summary and select on one row, then Previous, "Page X of Y", Next). Nothing new is drawn. Sizes are the sizes of the existing pattern: 5, 25, 50, 100 (default 25). API: total in `X-Total-Count`, array body unchanged. Keyboard and aria as Articles. The only difference from Articles: on a single page the page-size select is hidden too and the footer holds only the count line "N authors" (Articles keeps its summary and select). Existing frames of this screen that show a short list (the "Default" frames above) don't draw the count line yet; it appears whenever the list has loaded.
+

+## Changed in pass 3: site and authors
+
+Every existing Editor frame that has the details sidebar shows the "Site and authors" section collapsed, as the SPA renders it: one summary line ("Inès Duarte") because the install has one site and the article has an author, so there is no Site select. In the Loading frame the header is shown with a skeleton summary. The Not found frame has no editor, so it has no section. On mobile the section lives in the Details sheet, closed by default, so the mobile editor frames do not show it until the sheet is opened. The group below holds only the states specific to the feature.
+
+### Editor: site and authors (group "Editor: site and authors", 16 states)
+
+Route: `/article/:id/edit`. API: PATCH /v1/article/{id} {site_id, author_ids[]} · GET /v1/site/ · GET /v1/author/ · POST /v1/author/.
+
+States specific to this feature. The collapsed default (one site, the article has an author) and the Loading and Not found states are drawn in the existing Editor frames, which show the section in the same place; they are not repeated here. The section is open when the install has more than one site or the article has no authors, and collapsed to one summary line otherwise; the choice is remembered per browser. On mobile it is closed by default. With one site the Site select is not rendered. Anyone who can edit the article can set its site and pick authors; "Create author…", the Create author dialog and its "This is me" checkbox are for owner and admin only. For any other role, the "Create my author profile" hint (state 4) creates the profile directly with POST /v1/author/me, with no dialog, then shows the author in the list with a toast. Authors are a reorderable list; the first is the primary byline.
+
+| # | State | Trigger | Copy |
+|---|---|---|---|

+## Editor: search and sharing (SEO round)
+
+Route: `/article/:id/edit`. API: PATCH /v1/article/{id} {slug, excerpt, seo_title, seo_description, cover_image_id, cover_image_alt, social_title, social_description, social_image_id, canonical_url, noindex, seo_dismissed[]}.
+
+RenewCMS is headless: it never renders pages or adds meta tags. This section helps the writer fill in SEO data and shows what the frontend will receive. Everything is optional and each empty field shows its fallback. Placement: a "Search and sharing" section under "Site and authors" in the sidebar and in the mobile Details sheet. Collapsed by default with a one-line summary (Ready, N suggestions, Hidden from search), remembered per browser. The fields and live previews open in a slide-over (desktop, 960 px) or a 92% sheet over the Details sheet (mobile). Anyone who can edit the article can edit these fields. Suggestions never block saving or publishing: publishing is allowed regardless. Counters are soft guides and turn amber, never red, outside the recommended range. Light and dark follow the theme switch above.
+
+| # | State | Trigger | Copy |
+|---|---|---|---|
+| 1 | Collapsed: ready | The default. Nothing to suggest. | Search and sharing · Ready |

+| 4 | Open: ready | Address, the all-good message and two actions. | Address · renew.example/how-we-price-a-bathroom-renovation · All good · Nothing to suggest for this article. · Edit search and sharing · What the frontend gets |
+| 5 | Open: suggestions | At most three suggestions here, then a count. Each links to its field. | The meta title is 74 characters. Search engines may cut it off after about 60. · Go to meta title · The cover image has no alt text. Add a short description of it. · Go to cover image · The body has no headings. H2 headings help readers scan the article. · Go to body · +1 more in Search and sharing |
+| 6 | Open: checking | While the checks run after the editor loads. The rest of the section stays usable. | Checking this article… |
+| 7 | Open: hidden | A line explains the flag. | Hidden from search engines. This only sets a flag in the API. |
+| 8 | Open: other site | The address uses the article's site. | journal.renew.example/how-we-price-a-bathroom-renovation |
+| 9 | Panel: defaults | A writer who changed nothing. Every value is a fallback and says so. | Search and sharing · URL slug · Generated from the title until you edit it. · Meta title · Using article title · Recommended 30 to 60 characters. This is a guide, not a limit. · Meta description · Using first sentence of the body · Recommended 70 to 160 characters. · Excerpt · A short summary. It is also sent as the article teaser. · Cover image · Using the site social image (north-wall.jpg). · Social sharing · Optional · Uses the meta values · Advanced · Canonical URL: automatic · Hide from search engines · Sets noindex in the API. It doesn't change who can read the article. · Search result · Social card · Suggestions · What the frontend gets · Cancel · Save changes |
+| 10 | Panel: filled in | Own values everywhere. The fallback chips are gone and the suggestion list shows All good. | All good · Nothing to suggest for this article. |
+| 11 | Panel: outside the soft ranges | Counters turn amber. The preview shows the cut-off. Nothing is blocked. | The meta title is 74 characters. Search engines may cut it off after about 60. · The description is 41 characters. About 70 to 160 reads best in results. · Cut off here, the way a search engine would. |
+| 12 | Panel: slug edited | The Auto badge is gone. "Reset to match the title" brings it back. | Reset to match the title |
+| 13 | Panel: slug taken | Checked on blur and on save. Nothing is saved until a free slug is chosen. | The slug "bathroom-costs" is already used on Renew. · Use bathroom-costs-2 |
+| 14 | Panel: cover without alt | Alt text is required before the cover counts as ready. It is a suggestion, not an error. | Alt text · Needed before the cover counts as ready. Sent as image alt in the API. · Describe the image for people who can't see it · The cover image has no alt text. Add a short description of it. |
+| 15 | Panel: choose cover | The shared Media picker. | Choose a cover image · The cover for this article. · Use image |

+| 18 | Panel: advanced, invalid canonical | Collapsed by default. The address must be absolute. | Advanced · Canonical URL · Only change this if the same content lives at another address. · Enter a full address starting with https:// |
+| 19 | Panel: hidden from search | The switch only sets a flag in the API. | Hide from search engines · Sets noindex in the API. It doesn't change who can read the article. |
+| 20 | Panel: mobile search preview | The Desktop and Mobile toggle changes the width and where the title is cut. | Search result · Desktop · Mobile |
+| 21 | Panel: checking | Checks run on open and after each pause in typing. | Checking this article… |

+| 23 | Panel: save failed | 500 or network failure. The values stay. | Couldn't save search and sharing. Your changes are still here. Try again in a moment. |
+| 24 | Saved | The panel closes. The summary updates. | Search and sharing saved · Your search and sharing settings are up to date. |
+
+Mobile: the section sits under "Site and authors" in the Details sheet. "Edit search and sharing" opens a 92% sheet on top of the Details sheet, with suggestions first, then fields, then the two previews. Publishing is allowed regardless of suggestions; Save and Publish are never disabled by them.

+A read-only dialog (desktop, 720 px) or bottom sheet (mobile) with the resolved SEO object exactly as the API returns it. Opened from the sidebar section or the panel. Each value that came from a fallback carries a chip. Formatted shows a compact key and value list, Raw shows the JSON. Copy JSON copies the raw object. Author name, profile URL and social links come from the Authors screen and surface in authors[] and in the JSON-LD author, so Authors itself needs no change.

+# Integration: API keys
+
+Route: `/integration/api-keys`. Component: `ApiKeysPage.dc.html`, mounted by `AppFrame`.
+
+Visual reference: `RenewCMS Screens API keys.dc.html`.
+
+## API
+`POST /v1/api-key` · `GET /v1/api-key` · `DELETE /v1/api-key/{id}`. Access: Session only. An API key cannot manage keys; with a key these routes answer 403 "This action needs a real session."
+- `POST /v1/api-key` body: `name` (string, required, max 60), `expires_at` (RFC3339 string, optional, in the future). A past date answers 400 "The expiry must be a date in the future."
+- `DELETE /v1/api-key/{id}`: unknown id answers 404 "API key not found".
+
+## Placement
+Under Integration, as a sub-page linked from the Authentication section ("Manage API keys") and the sidebar item. Keys exist to call the API and admins can create them; Settings is owner-only today. The mobile top bar has a back arrow that returns to Integration.
+
+## Content
+- Columns: Name, Key (prefix, mono), Status (active, expired, revoked), Created by (owners only), Created, Last used, Expires, Revoke. Owners see all keys; admins see their own.
+- Create key modal: Name (required, up to 60, counter), Expiry date (optional, must be in the future). Errors: "Enter a name." / "Use 60 characters or fewer." / "Choose a date in the future."
+- The Expiry field is a native date input. The displayed format follows the browser's locale, so there is no custom format. The board draws one example date only.
+- One-time reveal: warning "You won't be able to see this key again.", the key in a CodeSnippet with one tab ("API key") and Copy / Copied, "Closing this window discards the key from the screen. Copy it first." Button "Done".
+- Revoke: "Revoke this key?" / ""Nightly media import" (rcms_Mq7b…) will stop working right away. Requests that use it answer 401. This can't be undone." Buttons "Keep key", "Revoke key". Toast "Key revoked".
+- Empty: "No API keys yet" / "Create a key to call the API from a script or service." Error: "Couldn't load your API keys" / "Check your connection and try again."
+- Note: "Resetting a user's password revokes all of their keys."
+
+## Mobile: pinned Create key
+On mobile the "Create key" button is pinned to the bottom of the viewport (44 px high, full width, on a bar with a top border). It shows in Owner list, Admin own keys only, Loading, Empty, Error and Revoked, and is hidden behind every modal state. In Empty it replaces the inline button. The content has bottom padding so nothing sits under the bar, and the toast sits above it. Desktop keeps "Create key" in the page header (and in the Empty card).
+
+## States
+Names are matched exactly by the visual-check script.
+- Owner: list
+- Admin: own keys only
+- Loading: the list request is in flight. Skeleton rows appear only after 150 ms.
+- Empty
+- Error: a 500 or network failure on the list request. If a key is created while this state is showing, the list reloads, the new key appears and the error alert is cleared.
+- Create key
+- Create key: validation
+- Create key: name too long
+- One-time reveal
+- One-time reveal: copied
+- Revoke: confirm
+- Revoked
+
+## Component inventory (Nuxt UI v4)
+`UTable`, `UBadge`, `UModal` (dialog on desktop, bottom sheet on mobile, footer secondary left and primary right) with `UForm`/`UFormField`/`UInput` (type date), `UAlert` color warning, `UButton`, CodeSnippet for the key.
+
+## Copy per state (generated from the board source, pass 2)
+
+Every state below is drawn in light and dark (theme switch on the board), at 1440×900 and 390×844 (both frames sit side by side). Board: `RenewCMS Screens API keys.dc.html`. Copy is exact; where a cell is empty the state reuses the fixed copy.
+
+### API keys (group "API keys", 12 states)
+
+Route: `/integration/api-keys`. API: GET /v1/api-key · POST /v1/api-key · DELETE /v1/api-key/{id} (session only).
+
+Recommendation: place it under Integration, as a sub-page linked from the Authentication section and from the sidebar item. Keys exist to call the API, so they belong next to the reference. Settings is owner-only today, but admins can also create keys. The screen is session only: an API key cannot manage keys. Key name: required, up to 60 characters. Expiry: optional, in the future. A key is shown in full once; afterwards only its prefix is visible.
+
+| # | State | Trigger | Copy |
+|---|---|---|---|
+| 1 | Owner: list | Owners see every user's keys and a "Created by" column. Expired keys keep their Revoke action. | "Integration" / "API keys" |
+| 2 | Admin: own keys only | Admins see only the keys they created, with no "Created by" column. | "Integration" / "API keys" |
+| 3 | Loading | The list request is in flight. Skeleton rows appear after 150 ms. | "Integration" / "API keys" |
+| 4 | Empty | No keys yet. | "Integration" / "API keys" |
+| 5 | Error | A 500 or network failure on the list request. | "Integration" / "API keys" |
+| 6 | Create key | "Create key" in the page header, or the bottom action on mobile. Name is required and limited to 60 characters; expiry is optional. | "Integration" / "API keys" |
+| 7 | Create key: validation | On submit or blur. Nothing is sent. The name is empty and the expiry is in the past. | "Integration" / "API keys" |
+| 8 | Create key: name too long | Over 60 characters. Checked as you type. | "Integration" / "API keys" |
+| 9 | One-time reveal | 201: the full key is shown once. Closing the dialog discards it from the screen. | "Integration" / "API keys" |
+| 10 | One-time reveal: copied | Copy was pressed. The button reads "Copied" for 2 s and this is announced. | "Integration" / "API keys" |
+| 11 | Revoke: confirm | Revoke on an active or expired row. | "Integration" / "API keys" |
+| 12 | Revoked | 204: the key stays in the list, greyed, with no Revoke action. A toast confirms. | "Integration" / "API keys" |
