-# 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.
-

-# Claude Design prompt: custom content types
-
-Paste everything below the line into Claude Design, with the existing RenewCMS design system attached.
-
----
-
-You are extending the RenewCMS back-office design. RenewCMS is a small self-hosted CMS (Go API plus a Vue 3 SPA built with Nuxt UI v4 and Tailwind 4). The existing screens, the AppFrame back-office shell, the AuthCard auth frames, the design tokens and the component inventory are already in this design system: reuse them, never invent new colors, spacing, radius or type values, and keep the same copy tone (short, plain, sentence case). Deliver the same artifacts the system already uses: one board per screen with every state, the exact copy per state, the routes with their auth requirement, the new components with their Nuxt UI mapping, and light and dark variants at desktop (1440x900) and mobile (390x844).
-
-## The feature
-
-Until now RenewCMS only managed fixed content: articles, authors, sites, media and users. We are adding custom content types: an owner or admin defines a content type (for example "Recipe" or "Event") made of ordered fields, and then any verified user creates entries of that type. Think of the clear part of Directus: a type is a collection, a field is a typed column. Do not copy Strapi's split between collections, components and fields into separate screens: everything about a type happens on one screen. Do not draw a table-builder feel with database jargon; speak in terms of content.
-
-The backend for the first part already exists. Design the full experience including the parts that come later, and mark each screen or state as "available now" or "later" (see the scope table).
-
-## What the backend does today (design against this, do not contradict it)
-
-Routes, all behind the normal signed-in, verified-user back-office session (cookie or API key):
-
-- GET /v1/content-type: list of types, ordered by name.
-- POST /v1/content-type, PUT /v1/content-type/{key}, DELETE /v1/content-type/{key}: owner or admin only.
-- GET /v1/content-type/{key}.
-- GET and POST /v1/content-type/{key}/entry; GET, PUT and DELETE /v1/content-type/{key}/entry/{id}. Any verified user.
-
-A content type: id, key, name, fields, created_at, updated_at.
-- key: lowercase slug, 2 to 40 characters, unique, chosen at creation, never editable afterwards. It appears in URLs and the API.
-- name: free text, up to 100 characters, editable.
-- fields: ordered list, 1 to 50 fields.
-
-A field: key, label, type, required, unique, default, min, max, options.
-- key: lowercase letters, digits and underscores, starts with a letter, up to 40 characters, unique within the type. It becomes the JSON key in the API.
-- label: the text shown in the editor.
-- type: one of text, richtext (markdown), number, boolean, date (a calendar date, no time), select (a single choice from a list of 1 to 50 distinct options).
-- required, unique (text, number, date and select only), default (applied only when an entry is created and the field is omitted), min and max.
-- min and max mean: length in characters for text and richtext, value for number, earliest and latest date for date. They do not exist for boolean and select. min must not exceed max. A default must satisfy the field's own rules. A unique field cannot have a default.
-- A field's type can never change after the type is saved, and the type key never changes.
-
-An entry: id, content_type (the type's key), data (an object keyed by field key), created_by, updated_by, created_at, updated_at.
-- Saving an entry replaces its whole data. Defaults apply only on create. An explicit empty value stays empty, and a required field cannot be empty.
-- Unknown keys are rejected. Values of a removed field disappear.
-
-Schema changes once entries exist:
-- Removing a field is allowed; its stored values stop being returned.
-- Every existing entry is re-validated against the new schema. If any entry would become invalid (a new required field without a default, a field made unique while duplicates exist, a tighter min or max below a stored value, a removed option still in use), the whole change is refused as incompatible and nothing changes.
-- Adding a required field is fine if it has a default.
-- A type that has entries cannot be deleted.
-
-Entry lists are paginated: page size 5, 25, 50 or 100 (default 25), sort by id, created_at or updated_at in either direction (default most recently updated first). There is no filtering or search on custom fields yet.
-
-Errors come back as plain text. Map each to friendly copy:
-- content_type_not_found, entry_not_found
-- content_type_key_taken
-- content_type_has_entries
-- invalid_content_type_key
-- invalid_field
-- schema_incompatible
-- "invalid_entry: <field key>: <rule>", rule being one of required, type, min, max, options, unique, unknown_field. Unique violations arrive as HTTP 409, the other entry rules as 422.
-- The usual 401, 403 (unverified account or insufficient role), 400 and 500 already covered in the system's HTTP-status-to-copy table.
-
-## Screens to design
-
-For each screen: every state (loading, empty, populated, error, forbidden, offline or failed save where relevant), the exact copy, the routes and their auth requirement, and a mobile layout.
-
-### 1. Schema screen: list of types (available now)
-Sits in the back-office navigation as "Schema", visible to owners and admins; other verified users do not see it. Shows the types as a list or table: name, key, number of fields, last updated. Shows the built-in types (Articles, Authors, Sites, Media, Users) in the same list with a "Built-in" badge and a lock icon. Built-ins are read-only entries here: they open a read-only view listing their fields, with no edit, no delete and no ability to add fields. Do not suggest that built-ins are custom collections; the badge and a one-line explanation make clear they are managed by RenewCMS. Primary action "New content type". States: loading, empty (no custom type yet: invite the user to create one, built-ins still listed), populated, error, forbidden (non-admin who types the URL).
-
-### 2. Schema builder (available now, the main screen)
-One screen with three regions, not three separate areas:
-- Left: the ordered field list. Reorder (drag with a keyboard-accessible alternative), add field, remove field. Each row shows label, key, type icon and small badges for required and unique.
-- Right: the field inspector for the selected field: label, key (generated from the label, editable until the type is first saved, then locked), type (a gallery of the six types with icon and one-line description), required, unique (disabled with an explanation where not allowed), default, min and max (with the right unit wording per type), and for select an options editor (add, remove, reorder, no duplicates, no blanks). Show the rules inline as the user types, not only after save.
-- Top: type name, type key (editable only at creation; afterwards locked with a tooltip explaining why), Save and Discard.
-- Live API preview: a collapsible panel showing the exact JSON an entry of this type looks like (a sample entry using each field's type and default) and the route it lives at, updating as fields change. Include a copy button.
-States: new type, editing an existing type, unsaved changes, validation errors per field and at type level (inline, with the field highlighted in the list), saving, saved, save failed, key already taken, schema incompatible with existing entries.
-
-### 3. Schema change review (available now for the review step, later for the diff)
-Before saving changes to a type that already has entries, show a review step: "Add 2 fields, change 1, remove 1", listing each change, with destructive ones (removing a field, removing an option, tightening a limit, making a field unique or required) clearly flagged. Because the server decides compatibility, the review is informational plus an explicit Apply button; if the server answers schema incompatible, show a refusal state that says nothing was changed and which kind of change likely caused it (we cannot tell which entry, so write copy that does not pretend to). Also design the "delete type" confirmation: blocked when entries exist (explain that entries must be deleted first) and a plain confirmation when empty. Mark per-change entry counts and a full diff as "later" (the API does not return them yet).
-
-### 4. Field-type gallery (available now)
-A reference board for the six field types showing, for each: its icon, its inspector options, its list cell (how a value renders in the entries table, including the empty state), its form control in the entry editor (markdown editor for richtext with preview, number input with min and max hints, toggle for boolean using the system's single toggle component, date picker, select, text with a character counter when a limit exists), and its error states per rule (required, type, min, max, options, unique). Show the "filter" widget for each type as "later" since filtering on custom fields is not available yet.
-
-### 5. Content navigation and entry list (available now)
-The back-office sidebar gets a "Content" group generated from the custom types, one entry per type (name, with the type's icon if any; truncated gracefully with many types; collapsed on mobile). The list screen for a type shows a paginated table with a column per field (cap the visible columns and let the user choose which, defaulting to the first few), plus created and updated dates and the author of the last change. Sort control (id, created, updated), page size selector (5, 25, 50, 100), "New entry" button. Row click opens the editor. States: loading, empty for this type (with a hint pointing to "New entry"), populated, error, forbidden, type not found.
-Use a sample "Events" type for all boards: title (text, required, unique, max 80), starts_on (date, required), ends_on (date), online (boolean, default false), capacity (number, min 1, max 5000), category (select: Talk, Workshop, Meetup), description (richtext).
-
-### 6. Entry editor (available now)
-Create and edit form generated from the schema, one control per field in schema order, with labels, required markers, helper text from min, max and options, a character counter where a limit exists, and inline errors per field. Show defaults pre-filled on create. Save, Cancel, Delete (with confirmation). Provenance footer: created by, updated by, dates. States: new, editing, unsaved changes, saving, saved, failed save, field errors for each rule, duplicate unique value (409), entry not found, concurrent schema change (a field disappeared or a new required field appeared since the form loaded: explain that the form must be reloaded).
-
-### 7. Relation field and sentence-style relation picker (later, design now)
-Relations are not built yet. Design the picker so that the model reads as sentences, not jargon: "Each Event has one Venue" and, beside it, "Each Venue has many Events", with a live preview of both sides. Offer the three relationship shapes in plain words. Show how a relation field renders in the inspector, the entry form (search and pick, with chips for many) and the list cell. Mark everything "later".
-
-### 8. Permissions grid (later, design now)
-A collection by action grid on the roles area: rows are types (custom and built-in), columns are read, create, update and delete, per role. Built-in rows are locked where the system dictates it. Make the grid usable on mobile (collapse to a per-role list). Mark "later". Today's rule is simple: owners and admins edit schema, any verified user reads and writes entries; show that as the default state of the grid.
-
-### 9. Schema export and import (later, design now)
-Export the whole schema or a single type to a file, import with a preview of what will be created or changed and the same compatibility review as screen 3, plus an explicit confirm. Aim at the dev-to-production flow. Mark "later".
-
-## Scope table to include in your answer
-
-For every screen and state, label it "available now" or "later" so engineering knows what is wired. Available now: screens 1 to 6 (except the diff counts), the live API preview, the type-level and field-level validation states. Later: relation picker, permissions grid, schema export and import, filters on custom fields, per-change entry counts, publish and draft state, public (anonymous) read access, activity log entries for types and entries.
-
-## Constraints
-
-- Nuxt UI v4 only, mapped to existing components in the inventory. List every new component you introduce with its Nuxt UI mapping and why an existing one does not fit.
-- Tokens only. No raw hex values and no arbitrary Tailwind colors.
-- Accessibility: keyboard reorder for fields, focus order, visible focus, labels on every control, error text tied to its input, sufficient contrast in light and dark.
-- Copy: short and plain, no database jargon in primary labels (say "field", "choice list", "entry", "content type"; keep "key" for the API identifier and explain it once).
-- Do not redesign existing screens. Only add what these screens need: new sidebar group, new routes, new components.
-- Provide the routes table: /schema, /schema/new, /schema/:key, /content/:key, /content/:key/new, /content/:key/:id, each with its auth requirement (schema routes owner or admin, content routes any verified user).
-- Anything the API cannot do today (see above) must not appear as if it works. If a design needs a backend capability that does not exist, flag it explicitly in a short "needs backend" list at the end.

+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.

+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.

+
+## 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.

+This release adds a Media field type to custom content types, shows where each image is used, makes merging duplicate images safe against concurrent edits, and replaces or updates dependencies to close known security advisories.
+
+## New
+
+**Media field**
+
+- A custom content type can now have a Media field that holds one image from the media library. The entry stores the image, not a copy, so the field always shows the current library image.
+- A Media field has a label, a key and a required switch. It has no default, unique, minimum, maximum or choices, and its type cannot change after the first save.
+- In the schema builder, Media is the seventh field type. Adding a required Media field to a type that already has entries is refused in the review step, because such a field cannot have a default.
+- In the entry editor, the field shows a thumbnail with Change image and Remove buttons, opens the library picker on click or keyboard, and can upload a new image from the picker's Upload tab. A required field has no "No image" choice.
+- When an image was deleted after an entry was saved, the entry keeps the link and the field shows "This image is no longer in the library". An optional field can still be saved, and a required one asks for a new image.
+- The entry list gets a Thumbnail column and a thumbnail on mobile cards. It can be added from the Columns menu or shown as the first column.
+
+**Image usage in the media library**
+
+- Entries now count as uses of an image, together with articles, authors and sites. The usage badge, the Unused filter and the unused count all include them.
+- Hovering or focusing a usage badge on a card shows how many articles and entries use the image.
+- The image detail panel has a "Used in entries" section listing each entry with its content type and title, as a link to the entry.
+- Deleting, bulk deleting and merging images now warn with counts of uses, and say what happens to entries that point at the image. Deleting a used image is still allowed and leaves the entries' data untouched.
+
+## Improvements and fixes
+
+- Merging duplicate images is now all-or-nothing. If any step fails, articles, entries and the library are left exactly as they were.
+- Stored files are removed only after the merge is committed. A file that cannot be removed afterwards is logged and does not undo the merge.
+- A merge no longer overwrites an article or entry edited while it was running. Articles and entries are re-read before they are rewritten, and ones deleted in the meantime are skipped.
+- A duplicate purge scans entries once instead of once per group, commits one group at a time, so one failing group no longer undoes the others, and stops cleanly when the request is cancelled.
+- Sessions now expire. New sign-in tokens carry a 24 hour expiry, matching the cookie. Sessions created before this release keep working until you sign out.
+
+## API
+
+- Changed: an entry response now has eight keys, the seven existing ones plus `media`. It is an object keyed by Media field key, `{}` when the type has no Media field. Each value is `{ "id", "filename", "width", "height", "size", "thumbnail_url" }` for an existing image, or `{ "id", "missing": true }` when the image is gone. `data` keeps the image id, or `null`, as the field's value. It is on `POST` (201), `PUT` (200), `GET` one and every item of the list.
+- `POST /v1/content-type` and `PUT /v1/content-type/{key}` accept fields of type `media`. A Media field with `unique`, `default`, `min`, `max` or `options` answers `422` `invalid_field`.
+- `POST` and `PUT` on `/v1/content-type/{key}/entry` check that a new or changed image id exists in the library, otherwise `422` `invalid_entry: <key>: type`. A required Media field that is empty, or whose stored image is gone, answers `422` `invalid_entry: <key>: required`.
+- Changed: `used_in` on `GET /v1/media/` and `GET /v1/media/{id}` now includes entries, and `filter=unused` and `counts.unused` treat an image used by an entry as used.
+- Changed: `GET /v1/media/{id}/usage` also returns items of type `entry`, with `id`, `fields`, `content_type_key`, `content_type_name` and `first_field` (`key`, `type` and the raw stored `value`). They follow the article, author and site items, ordered by content type name and then id. Existing item shapes are unchanged.
+- Merging duplicates, by hand or through the purge, now repoints entry Media values to the kept image.
+
+## Under the hood
+
+- Seven direct and twelve indirect Go modules are gone. Sign-in tokens, SMTP delivery, `.env` loading, CORS, request logging and the image-variant single-flight group are now small in-repo implementations on the standard library, with tests. The removed modules are `jwtauth`, `lestrrat-go/jwx`, `gomail`, `httplog`, `godotenv`, `go-chi/cors` and `x/sync/singleflight`, and the dependencies they pulled in.
+- Every remaining Go module is updated, and the Go toolchain moves to 1.27.3. `govulncheck` reports no vulnerability reachable from the code, where it found thirteen in the standard library and several in `golang.org/x/net` and `chi` before.
+- Web dependencies are updated, which clears all but three dev-only audit findings. `npm-run-all2` is removed, and `bun run build` now runs the type check and then the build.
+- A transaction port in the domain lets use cases commit several writes together, with a GORM adapter that works on SQLite, MySQL, MariaDB and PostgreSQL.
+- Feature specs and QA procedures for each slice are in `features/`.
+
+## Upgrading
+
+- Replace the binary, or pull the new image. Back up the database first as usual.
+- No schema change and no new environment variable. A Media field is stored in the existing content type and entry tables.
+- `.env` files no longer expand `$VARIABLES` and do not support multi-line values. A malformed line now makes the file ignored, and the server logs the line number. Real environment variables still take precedence.
+- If you build the image yourself, the Go base image is now `golang:1.27.3-alpine`.
+- SMTP now fails with a clear error when a login is set but the server offers no authentication, where it used to continue without logging in. Credentials are never sent in clear text to a host other than localhost.
+- `CORS_ALLOWED_ORIGINS` also accepts one `*` per entry, for example `https://*.preview.example.com`, and a lone `*` for any origin. Credentials are never allowed cross-origin.
+
+## Known limitations
+
+- A Media field holds one image. Galleries are not supported.
+- Entries still cannot be filtered or searched by their field values, and there are no relations between types.
+- The editor preview of a Media field uses the original image, with no variant choice.

+Feature: Media field usage in the Media library
+  As an owner, admin or verified user managing the media library
+  I want to see which entries use an image and be warned before deleting it
+  So that I know what an image is used for and what a delete will break
+
+  Background:
+    Given the SPA calls the API with relative URLs under /v1 and the "jwt" HttpOnly cookie
+    And API errors are plain text
+    And this slice changes only web/ (and web/visual); the backend of features/media_field_type.feature is done and not touched
+    And the design is docs/design/media-field-changes.md section 3.8 and section 4, with the board group "11 Media library: usage" (4 states) of "RenewCMS Screens Schema.dc.html", which draws MediaFrame.dc.html with entries counted as uses
+    And GET /v1/media/ items carry "used_in", which counts articles, authors, sites and entries together, and no split
+    And GET /v1/media/{id}/usage answers an array ordered articles, authors, sites, then entries by content type name then entry id, with no total and no "first few" wrapper
+    And an article item is {"type":"article","id","title","published","fields"}
+    And an entry item is {"type":"entry","id","fields","content_type_key","content_type_name","first_field":{"key","type","value"}} with no title and no published, and first_field absent when the type has no first field
+    And the SPA keeps the first 3 entry items, counts the rest, and derives the entry title from first_field with the title rules of the entry list (see "Entry title in the usage lists")
+    And deleting a used image stays allowed; entries keep the id and show "This image is no longer in the library"
+    And the usage badge, panel and dialog never branch on the role; the Media page is the same for every user who reaches it
+    And sentence case, "image" and never "asset", buttons are verbs
+    And every string goes through t() and has a French entry in i18n/messages.ts
+    And a copy tagged "(proposed copy)" is not in the design and is the coder's single point of change
+    And decisions D1 to D12 of this slice are listed in the QA procedure header and in the conversation
+    And out of scope: filtering the library by media-field use, the read-only view of a custom type, any change to the Go API
+
+  Scenario Outline: The label of the usage badge
+    Given an image with used_in <used_in>
+    Then the badge reads "<badge>"
+
+    Examples:
+      | used_in | badge     |
+      | 0       | Unused    |
+      | 1       | Used in 1 |
+      | 3       | Used in 3 |
+      | 7       | Used in 7 |
+
+  Scenario: The badge counts articles and entries together
+    Given bathroom-tiles.png has used_in 3 (0 articles, 3 entries) and lime-plaster.jpg has used_in 7 (2 articles, 5 entries)
+    Then the grid card, the list row and the mobile card of bathroom-tiles.png read "Used in 3" and those of lime-plaster.jpg read "Used in 7"
+    And the badge is the outline kind of MediaBadge, without an icon, as today
+
+  Scenario: Tooltip for entries only (design "Grid: usage badge tooltip")
+    Given bathroom-tiles.png has 0 articles and 3 entries, and a desktop viewport
+    When the pointer rests on the badge "Used in 3"
+    Then GET /v1/media/10/usage is sent once
+    And a tooltip (--ui-bg-inverted, --ui-text-inverted, 12/18, 6 px 8 px padding, below the badge, left aligned) reads on one line "Used in entries: 3"
+
+  Scenario: Tooltip for articles and entries
+    Given lime-plaster.jpg has 2 articles and 5 entries, and a desktop viewport
+    When the pointer rests on the badge "Used in 7"
+    Then the tooltip reads "Used in articles: 2" on the first line and "Used in entries: 5" on the second
+
+  Scenario: Tooltip for articles only
+    Given north-wall.jpg has 2 articles and 0 entries, and a desktop viewport
+    When the pointer rests on the badge "Used in 2"
+    Then the tooltip reads "Used in articles: 2" and no "Used in entries" line shows
+
+  Scenario: Tooltip opens on keyboard focus
+    Given a desktop viewport
+    When the keyboard focus reaches the card (grid) of an image that is used
+    Then the same tooltip opens, and it closes on blur or Escape without closing anything else
+    And the focus ring of the card is unchanged
+
+  Scenario: The usage is fetched once per image
+    Given the tooltip of image 10 was opened once
+    When the user hovers it again, or opens its detail panel
+    Then no second GET /v1/media/10/usage is sent while the list is not reloaded
+    And a reload of the list (search, filter, sort, page, retry) clears the cached usage
+
+  Scenario: The tooltip waits for the usage
+    Given GET /v1/media/10/usage has not answered
+    Then no tooltip shows and the badge keeps its label
+    When it answers and the pointer or focus is still on the badge
+    Then the tooltip opens
+
+  Scenario Outline: The tooltip never shows without a useful split
+    Given the pointer rests on the badge of an image and GET /v1/media/{id}/usage <outcome>
+    Then no tooltip shows and nothing else changes
+
+    Examples:
+      | outcome                         |
+      | answers 500                     |
+      | fails on the network            |
+      | answers 404                     |
+      | answers only authors and sites  |
+
+  Scenario: No tooltip on mobile
+    Given a 390 px viewport
+    Then no tooltip opens on tap and the badge is read inside the card as "Used in 3"
+
+  Scenario: No tooltip on an unused image
+    Given an image with used_in 0
+    Then the badge "Unused" has no tooltip and no usage request is sent for it
+
+  Scenario Outline: The accessible name of a card (proposed copy)
+    Given an image "north-wall.jpg", 3.9 MB, with used_in <used_in>
+    Then the card button is named "<name>"
+
+    Examples:
+      | used_in | name                                     |
+      | 0       | north-wall.jpg, 3.9 MB, unused           |
+      | 1       | north-wall.jpg, 3.9 MB, used in 1 place  |
+      | 7       | north-wall.jpg, 3.9 MB, used in 7 places |
+
+  Scenario: The list table column (design "List view: usage badge", written spec 3.8)
+    Given a desktop viewport and the list view
+    Then the "Used in" column of a used image is the underlined button "Used in 3" that opens the detail panel, as the "N articles" button does today
+    And an image with used_in 0 shows the "Unused" badge
+    And the mobile card shows the "Used in 3" badge and the existing meta line
+
+  Scenario: Panel for an image used by articles and entries (design "Detail panel: used in entries")
+    Given lime-plaster.jpg has 2 articles and 5 entries, whose first three entries are Events "Lime plaster workshop", Events "Heritage stone walk" and Events "Winter open day"
+    When the user opens its panel
+    Then the preview is 16:10 on desktop and 16:3.6 on mobile only when usage holds at least one entry, and 16:10 and 4:3 otherwise
+    And the section "Used in 2 articles" lists the two articles with title, Online or Draft and the arrow-up-right icon, as today, with the note "Counted from the text of your articles each time you open this page."
+    And below it the section "Used in entries" (600 14/22, 8 px gap) holds a bordered list of 3 rows, then the row "and 2 more" in the muted colour, with a muted top border and no link
+    And each entry row is 36 px high on desktop and 48 px on mobile and holds, left to right, the content type name in 12 px muted (52 px wide, one line, ellipsis), the entry title as a link in weight 500 underlined (one line, ellipsis) and the arrow-up-right icon (14 px, muted)
+    And the link of a row goes to /content/events/<id> in the same tab
+
+  Scenario Outline: Counts in the "Used in entries" section
+    Given an image whose usage holds <entries> entry items
+    Then the section shows <rows> rows and <more>
+
+    Examples:
+      | entries | rows | more                   |
+      | 1       | 1    | no "and N more" row    |
+      | 3       | 3    | no "and N more" row    |
+      | 4       | 3    | the row "and 1 more"   |
+      | 5       | 3    | the row "and 2 more"   |
+      | 120     | 3    | the row "and 117 more" |
+
+  Scenario: Entries only, no article
+    Given bathroom-tiles.png has 3 entries and 0 articles
+    When the user opens its panel
+    Then the articles heading reads "Not used in any article"
+    And the line under it reads "No article shows it." and never "This image is safe to delete."
+    And the section "Used in entries" follows
+
+  Scenario: Articles only
+    Given north-wall.jpg has 2 articles and 0 entries
+    Then the panel is unchanged from before this slice and shows no "Used in entries" section
+
+  Scenario: Nothing uses the image
+    Given window-frame.jpg has used_in 0
+    Then the panel reads "Not used in any article" and "This image is safe to delete. No article shows it."
+    And no usage request is sent
+
+  Scenario: Authors and sites only (decision D7)
+    Given an image with used_in 2 and a usage that holds one author and one site
+    Then the articles heading reads "Not used in any article"
+    And the line reads "No article shows it." and no "safe to delete" claim is made
+    And no authors or sites are listed
+
+  Scenario: The articles heading counts articles only
+    Given lime-plaster.jpg has used_in 7 (2 articles, 5 entries)
+    Then the heading reads "Used in 2 articles" and never "Used in 7 articles"
+
+  Scenario: Entry link keyboard and focus
+    Given the panel of lime-plaster.jpg is open
+    Then Tab reaches the articles links, then the entry links, in reading order
+    And an entry link has the 2 px --ui-primary focus ring with a 2 px offset
+    And "and 2 more" is not a stop
+
+  Scenario: Usage loading in the panel (decision D6)
+    Given GET /v1/media/11/usage has not answered
+    Then after 150 ms a skeleton of three rows shows under the heading "Used in" (proposed copy)
+    And before 150 ms nothing shows in the section
+    And Copy URL, Rename and Delete stay enabled
+    When it answers
+    Then the real sections replace the skeleton
+
+  Scenario Outline: Usage failure in the panel (decision D5)
+    Given the panel of an image with used_in 7 is opened
+    When GET /v1/media/{id}/usage <outcome>
+    Then <result>
+
+    Examples:
+      | outcome              | result                                                                                                                                   |
+      | answers 500          | the section reads "Couldn't load where this image is used." (proposed copy) with the ghost button "Try again", and Delete stays enabled |

+      | answers 404          | the existing gone flow: the panel closes and "That image no longer exists" shows                                                         |
+      | answers 401          | the global redirect, no local copy                                                                                                       |
+
+  Scenario: Try again in the panel
+    Given the usage failure is shown
+    When the user activates "Try again"
+    Then only GET /v1/media/{id}/usage is sent again and the sections replace the message
+
+  Scenario: Switching images while the usage is loading
+    Given the panel of image 10 is waiting for its usage
+    When the user opens image 11
+    Then the answer of image 10 is ignored and the panel shows only image 11 data
+
+  Scenario Outline: Entry title from first_field
+    Given an entry item with id 42 and first_field {"key":"title","type":"<type>","value":<value>}
+    Then the row title reads "<title>"
+
+    Examples:
+      | type     | value                           | title                                                                                   |

+
+  Scenario: first_field is absent or unknown
+    Given an entry item with id 42 and no first_field, or a first_field of an unknown type
+    Then the row title reads "Entry 42" for no first_field and the String of the value for an unknown type, as describeCell does for the default case
+
+  Scenario: Long titles and long type names (decision D4)
+    Given an entry title of 120 characters and the type name "Press mentions and partner coverage"
+    Then both stay on one line with an ellipsis, the row height does not change, the title link keeps the full title as its accessible name and a native title attribute, and "and N more" is unaffected
+
+  Scenario: The order of the three rows
+    Given the API returns entries ordered by content type name then entry id
+    Then the three kept rows keep that order and the SPA does not sort again
+
+  Scenario: Delete an image used by entries and articles (design "Delete: image used by entries")
+    Given lime-plaster.jpg has 2 articles and 5 entries and the user activates Delete in its panel
+    Then the confirm dialog (ConfirmDialog, tone danger) titled "Delete an image that's in use?" opens
+    And its description reads "\"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."
+    And the body holds, in this order, the bordered "Used in entries" list (heading "Used in entries", 3 rows, then "and 2 more") and the bordered list of the 2 articles with title and Online or Draft
+    And the buttons are "Cancel" and the destructive "Delete image"
+    And the entry rows show the type name and the title and are not links in the dialog (decision D10)
+
+  Scenario Outline: The wording by what uses the image
+    Given an image "lime-plaster.jpg" with <articles> articles and <entries> entries in its loaded usage
+    Then the title is "<title>"
+    And the description reads <description>
+
+    Examples:
+      | articles | entries | title                          | description                                                                                                                                                                                   |
+      | 2        | 5       | Delete an image that's in use? | "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. |
+      | 1        | 1       | Delete an image that's in use? | "lime-plaster.jpg" is used in 1 entry and 1 article. 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.   |
+      | 2        | 0       | Delete an image that's in use? | "lime-plaster.jpg" is used in 2 articles. If you delete it, they will show a broken image. This can't be undone.                                                                               |
+      | 0        | 3       | Delete an image that's in use? | "lime-plaster.jpg" is used in 3 entries. Those entry fields will show "This image is no longer in the library". This can't be undone. (proposed copy)                                         |
+      | 0        | 0       | Delete this image?             | "lime-plaster.jpg" will be deleted from your library. No article uses it. This can't be undone. (used_in is 0)                                                                                 |
+
+  Scenario: Delete an unused image
+    Given window-frame.jpg has used_in 0
+    Then the dialog is titled "Delete this image?" with the unchanged copy, no lists and no usage request
+
+  Scenario: Delete an image used only by authors or sites
+    Given used_in 2 and a usage with no article and no entry
+    Then the existing in-use title shows with the generic fallback description of the next scenario
+
+  Scenario: The usage is not ready when the dialog opens (decision D6)
+    Given the user activates Delete before GET /v1/media/{id}/usage answered, or after it failed
+    Then the dialog is titled "Delete an image that's in use?" because used_in is above 0
+    And the description reads "\"lime-plaster.jpg\" is in use. Articles will show a broken image and entry fields will show \"This image is no longer in the library\". This can't be undone." (proposed copy)
+    And no lists show, "Delete image" is enabled, and when the usage answers while the dialog is open the dialog switches to the full copy and lists without moving the focus
+
+  Scenario: Confirm and results
+    Given the delete dialog is open
+    When the user activates "Delete image"
+    Then DELETE /v1/media/<id> is sent and the existing in-progress, failed, done and 404 states run unchanged
+    And on 204 the toast "Image deleted" / "\"lime-plaster.jpg\" is gone from your library." shows and the focus moves to the next item
+
+  Scenario: Cancel and Escape
+    When the user activates "Cancel" or presses Esc
+    Then nothing is deleted and the focus returns to the Delete button of the panel
+
+  Scenario: The variants note is kept
+    Given an image with cached variants and used by entries
+    Then the existing variant removal note still shows under the lists
+
+  Scenario: Mobile dialog
+    Given a 390 px viewport
+    Then the dialog is a bottom sheet, the entry rows are 48 px high and the buttons are 44 px high
+
+  Scenario: Bulk delete counts uses, not articles (proposed copy)
+    Given 3 images are selected, 2 of them used for 7 places in total (articles and entries)
+    Then each row keeps its badge "Used in N" or "Unused"
+    And the description counts "7 places" in the sentence where it said "7 articles" and reads "which will show a broken image or a missing-image notice." instead of "which will show a broken image."
+    And no usage request is sent for the bulk dialog
+
+  Scenario: Merge counts uses, not articles (proposed copy)
+    Given a merge group whose other copies have used_in 5 and 2
+    Then the dialog says "7 places will be updated" and "Kept · used in N places now"
+    And the toast after the merge keeps "N copies merged. M articles updated." from articles_updated
+
+  Scenario: Accessibility of the usage UI
+    Then the tooltip is exposed with aria-describedby on its trigger and uses role "tooltip"
+    And the entry title link is named "<title>, <content type name>" (proposed)
+    And "and 2 more" is plain text read in order
+    And the arrow-up-right icon is aria-hidden
+    And a skeleton or error line in the panel is inside the section so a screen reader reads it after the heading
+    And the delete dialog moves focus to "Cancel" as it does today, and its lists are read after the description
+    And mobile targets are 44 px, with rows of 48 px, and there is no hover on mobile

+# QA: Media field usage in the Media library (slice C)
+
+Runner: Vitest + Vue Test Utils (`task test:web`). No Go test and no Go change: the usage API is covered by features/media_field_type.qa.md. Kit: extend the Media view test kit with
+- the library list (`GET /v1/media/?page=&size=&q=&filter=` with `items`, `total`, `counts`);
+- `GET /v1/media/{id}/usage` fixtures:
+  - image 10 `bathroom-tiles.png`: 3 entries (Events), `used_in` 3;
+  - image 11 `lime-plaster.jpg`: 2 articles ("Open day at the workshop" online, "Restoring lime plaster" draft) plus 5 Events entries (first three: first_field text "Lime plaster workshop", "Heritage stone walk", "Winter open day"), `used_in` 7;
+  - image 1 `north-wall.jpg`: 2 articles, `used_in` 2;
+  - image 8 `window-frame.jpg`: `used_in` 0;
+  - an author-and-site-only image, `used_in` 2;
+- entry items of every `first_field.type`, plus items with no `first_field`;
+- failures: 500, network, 429, 404, 401.
+
+Pin the time zone; never freeze the system date. No state of this slice depends on the clock.
+
+Decisions accepted by the user (all as the feature draft assumes):
+- D1 split source for the tooltip: lazy `/usage` fetch, SPA-only.
+- D2 wording of the card name and the table column: "used in N places", underlined "Used in N" button.
+- D3 title derivation: reuse `describeCell` and `plainCellText`.
+- D4 truncation: one line, ellipsis, native title.
+- D5 usage failure: inline message with "Try again" in the panel, silent tooltip.
+- D6 usage loading: skeleton after 150 ms, delete dialog opens at once with a generic description.
+- D7 authors and sites in the usage: filtered out, heading counts articles only.
+- D8 bulk delete: "N places".
+- D9 merge: "N places".
+- D10 entry rows in the delete dialog are not links.
+- D11 mobile panel as drawn.
+- D12 visual gate setup.
+
+## Automated
+
+Pure logic (lib/__tests__, it.each over the feature's Examples):
+1. `splitUsage(items)`: articles are those with `type === 'article'`, entries those with `type === 'entry'`, authors and sites are counted by neither. Entry rows keep API order, the first 3 are kept, `more` is the rest (0, 1, 2, 117). An absent array gives zeros.
+2. `usageEntryTitle(item)`: the table "Entry title from first_field" for text, richtext (empty and Markdown), number (0 and 1500), boolean, date, select, media and null, empty string, absent first_field and an unknown type (falls to the default case of `describeCell`). It reuses `describeCell` and `plainCellText`; no second title rule exists. `entryTitle` itself is unchanged and its existing specs pass untouched.
+3. Wording helpers: pluralEntries ("1 entry", "5 entries"), usage description by case (articles+entries, singular forms, articles only unchanged, entries only, usage unavailable fallback), `usedInLabel` for the card name ("used in 1 place", "used in 7 places", "unused").
+4. Tooltip lines: entries only gives one line, both gives articles first, articles only gives one line, authors or sites only gives none.
+
+MediaCardBadges, MediaTable, MediaGrid, MediaCardList (components/__tests__):
+5. Badge label for used_in 0, 1, 3, 7. Outline kind, no icon. Same label in the grid card, the list row (underlined button in the table, badge in the mobile card) and the mobile card.
+6. Tooltip: hover on the badge (`pointerenter`) fetches `/usage` once and opens with the right lines for the three splits; focus on the grid card opens it; Escape and blur close it without closing the panel; no fetch for `used_in` 0; no tooltip on mobile (viewport helper 390); nothing opens while the request is pending, and it opens on answer if the pointer is still there; failures (500, network, 404, authors-only) leave no tooltip; the usage is cached per image and cleared on reload of the list.
+7. Card `aria-label`: the three names of the feature, replacing the "used in 2 articles" assertions in the existing specs; update those specs and change nothing else in them.
+8. Table: the "Used in" cell is the underlined button "Used in N" (`data-testid="media-used-in"` kept) that opens the panel; "Unused" badge at 0.
+
+MediaDetailPanel (components/__tests__/MediaDetailPanel.spec.ts, views/__tests__/MediaView*.spec.ts):
+9. Articles and entries: heading "Used in 2 articles" built from the articles of the usage, not from `used_in`; article rows unchanged; "Used in entries" heading and 3 rows with type name, title link to `/content/<key>/<id>` and the arrow icon; "and 2 more" as plain text; the counts table (1, 3, 4, 5, 120 entries); row heights 36 px (desktop) and 48 px (mobile) as classes.
+10. Entries only: heading "Not used in any article" with "No article shows it."; articles only: no entries section and the panel as before; unused: "safe to delete" line and no `/usage` request; authors and sites only: "No article shows it." and no list.
+11. Preview aspect: 16:10 desktop and 4:3 mobile without entries, 16:6 desktop and 16:3.6 mobile with entries (classes, after the usage answers).
+12. Loading: nothing before 150 ms, the three-row skeleton after, the real sections after the answer; fake timers only for the 150 ms delay, never the date. Failure: 500, network and 429 show "Couldn't load where this image is used." with "Try again" that repeats only `/usage`; 404 runs the existing gone flow; 401 is left to the global redirect; Delete stays enabled; switching images ignores the late answer.
+13. Long title and long type name: one line, ellipsis classes, native title attribute on the link, row height unchanged.
+14. Focus and tab order: article links, then entry links; the ring classes on a link; "and 2 more" not focusable.
+
+DeleteMediaDialog (components/__tests__/DeleteMediaDialog.spec.ts):
+15. The description table (2/5, 1/1, 2/0, 0/3, 0/0), the title for in use vs unused, the body order (entries list with heading and "and 2 more", then the articles list), the buttons, the variants note kept, no link in the entry rows.
+16. Usage not ready (pending, failed): the generic description, no lists, "Delete image" enabled; when the usage answers while open the copy and lists switch and the focus stays.
+17. Delete flow (confirm, in progress, failed, done, 404) runs unchanged; Cancel and Esc return focus to the Delete button of the panel.
+
+BulkDeleteMediaDialog and MergeMediaDialog:
+18. Bulk description counts "places" and uses "which will show a broken image or a missing-image notice."; rows and badges unchanged; no `/usage` request.
+19. Merge dialog says "N places will be updated" and "Kept · used in N places now"; the toast stays "N copies merged. M articles updated.".
+
+Cross-cutting:
+20. French: every new string has an entry (the i18n completeness spec passes).
+21. Regression: the existing Media view specs pass unchanged except the assertions named in 7, 18 and 19; if any other spec needs an edit, stop and report.
+
+## Visual (task visual:check -- media)
+
+In scope: the 4 states of the board group "11 Media library: usage" of RenewCMS Screens Schema.dc.html (they draw MediaFrame, and the copy list gives them the sample data). Every capture must be within 10 %, desktop and mobile, light and dark. Out of scope: states whose setups exist already and whose data does not change (they must keep passing untouched), and the picker states of slice B.
+
+Prerequisites in web/visual, no change under docs/design (decision D12):
+- `check.ts`: add the source `{ board: 'RenewCMS Screens Schema.dc.html', group: '11 Media library: usage', states: [the four below] }` to `extraSources.media`. The group differs from the screen's primary group ("Media"), so no merge change is needed.
+- `states.ts`: the four setups, with the media API mock extended by `GET /v1/media/10/usage` and `GET /v1/media/11/usage` (shapes above). Existing media states keep their data, so `used_in` stays articles-only there.
+- Board data:
+  - image 10 bathroom-tiles.png, 3 entries, `used_in` 3;
+  - image 11 lime-plaster.jpg, 2 articles and 5 entries, `used_in` 7;
+  - the grid also holds an unused image, so "Unused" shows in the captures.
+
+| Board state | Setup in web/visual/states.ts | Board sample data |
+|---|---|---|
+| Grid: usage badge tooltip | /media with ent counts; step: hover the badge of image 10 (desktop), wait for the tooltip; mobile shows the grid with no tooltip | "Used in 3", tooltip "Used in entries: 3", "Unused" |
+| List view: usage badge | /media?view=list; desktop table, mobile cards | "Used in 3", "Used in 7", "Unused" |
+| Detail panel: used in entries | step: open image 11; wait for the entries list | "Used in 2 articles", "Used in entries", Events + "Lime plaster workshop", "Heritage stone walk", "Winter open day", "and 2 more" |
+| Delete: image used by entries | step: open image 11, activate Delete; wait for the lists | the title, the description of 5 entries and 2 articles, both lists, "Cancel", "Delete image" |
+
+Board caveats to report, never hide:
+- The desktop table of the board draws `usedLink` with `pl(im.used)` (articles only). It shows "N articles" for lime-plaster.jpg and "Unused" for bathroom-tiles.png, while the written spec 3.8 says the list row carries the same badge. The spec follows the written text (D2); if the desktop capture of "List view: usage badge" exceeds 10 % the exception needs the user's explicit approval (`approvedBy`).
+- The board draws the entry rows in the delete dialog as underlined links with the arrow icon; the spec renders plain rows (D10). If a capture exceeds 10 %, report it before changing the choice.
+- The tooltip is drawn at a fixed place (left aligned, 26 px below the badge); a Nuxt UI tooltip may centre it. Use the `align` and offset that match the frame.
+- The board titles ("Lime plaster workshop") come from the setup's `first_field` values, not from a title field.
+- Clock-sensitive: none of the four states shows a relative date.
+
+## Manual
+
+- Real backend, owner and a second verified user: upload an image, use it in an article and in two entries through a Media field, and read "Used in 3" in the grid, list and mobile card. Hover and focus the badge for the tooltip, and check that a card with no entries shows "Used in articles: N" only.
+- Open the panel: the entries link opens /content/<key>/<id> and shows the right entry. Add a fourth entry and read "and 1 more". Delete the entry and reload: counts fall.
+- Delete the image from the panel with the dialog open: read the real counts, confirm, then open one of the entries and see "This image is no longer in the library" with the id kept.
+- Throttle or kill the network while opening the panel and the dialog: the error line, "Try again" and the generic delete description.
+- An image used only by an author or a site: no "safe to delete" claim anywhere.
+- Keyboard: tab order across card, badge tooltip (focus), panel links and dialog buttons; Escape closes the tooltip first, then the panel; the focus return after Cancel; screen reader reads the card name, the tooltip and the lists.
+- Motion and hover: the tooltip opening and closing, the skeleton fade at 150 ms, no layout jump larger than the preview change when the usage answers.
+- Mobile: the full-screen panel, 48 px rows, the bottom-sheet dialog, 44 px targets, no tooltip.
+- Contrast of the tooltip pair and of the muted type name in light and dark.

+Feature: Media field type in the SPA
+  As an owner or admin building a content type, and as a verified user filling an entry
+  I want a Media field that holds one image from the media library
+  So that entries link to a library image and always show its current version
+
+  Background:
+    Given the SPA calls the API with relative URLs under /v1 and the "jwt" HttpOnly cookie
+    And API errors are plain text
+    And this slice changes only web/ (and web/visual); the backend of features/media_field_type.feature is done
+    And the design is docs/design/media-field-changes.md sections 1, 2, 3.2 to 3.7, 4, 6 and 7, with the board groups 2 Schema builder, 3 Review and delete, 4 Field types, 5 Content and entry list, 6 Entry editor and 10 Media picker for fields of "RenewCMS Screens Schema.dc.html"
+    And the registry is lib/fieldTypes with lib/entryEditors, the single source for the builder, the list cells and the entry form; no screen branches on the type name "media" where a registry property can say it
+    And a media value is the id of a library image (a uint32 of at least 1) or null
+    And every entry answer (POST 201, PUT 200, GET one, each list item) carries a top-level "media" object keyed by media field key: {"id","filename","width","height","size","thumbnail_url"} for an existing image, or {"id","missing":true} when the image is gone; a null value has no key
+    And the API refuses with 422 "invalid_entry: <key>: required" or "invalid_entry: <key>: type", 409 "schema_incompatible" for a new required media field on a type with entries, and 422 "invalid_field" for forbidden options
+    And the picker is the existing ImageUploader with MediaPicker, loading GET /v1/media/?page=&size=&q= with the total in the "counts" and "total" fields as the article picker does; the Sites, Authors, SEO and article pickers are unchanged
+    And the picker in field mode never requests /v1/image-variants and never shows the variant select or the alt text
+    And the form dimming stays the entry form's 70 % (design conflict 12, existing rule kept); inside the control the thumbnail drops to 60 % and the buttons take the disabled look
+    And sentence case, "image" and never "asset", buttons are verbs
+    And every string goes through t() and has a French entry in i18n/messages.ts
+    And a copy tagged "(proposed copy)" is not in the design and is the coder's single point of change
+    And user decisions already taken: Apply is disabled for the certain refusal; thumbnail after Description in schema order; "Clear"; "1600 × 900 · 240 KB"; "Use this image" and "Remove image"; "Pick an image" on optional fields; row heights 48 and 68
+    And out of scope (slice C): "Used in" badge, usage panel and delete warning of the Media library, the read-only view of a custom type, filtering by media
+
+  Scenario Outline: Media in the registry
+    Given the registry entry for "media"
+    Then <property> is <value>
+
+    Examples:
+      | property                  | value                                                                                         |
+      | type name in the API      | media (the seventh entry, after select)                                                       |

+
+  Scenario Outline: Client validation of a media value
+    Given a media field "Thumbnail" that is <required>
+    When the value is <value>
+    Then the rule is <rule>
+
+    Examples:
+      | required | value        | rule     |
+      | required | null         | required |
+      | required | undefined    | required |
+      | optional | null         | none     |
+      | optional | 7            | none     |
+      | required | 7            | none     |
+      | optional | 0            | type     |
+      | optional | -1           | type     |
+      | optional | 7.5          | type     |
+      | optional | "7"          | type     |
+      | optional | true         | type     |
+      | optional | 4294967296   | type     |
+
+  Scenario Outline: Messages of a media field
+    Given a media field labelled "Thumbnail"
+    Then the message of the rule <rule> reads <message>
+
+    Examples:
+      | rule     | message                                       |
+      | required | Pick an image for Thumbnail.                  |
+      | type     | Thumbnail must be an image from the library.  |
+      | min      | not produced for media                        |
+      | max      | not produced for media                        |
+      | options  | not produced for media                        |
+      | unique   | not produced for media                        |
+
+  Scenario: A loaded media field is not shown as Text
+    Given GET /v1/content-type/events returns a field {"key":"thumbnail","label":"Thumbnail","type":"media","required":false,"unique":false,"default":null,"min":null,"max":null,"options":[]}
+    Then the builder, the entry form and the list resolve it to the media entry of the registry, never to the fallback type "text"
+
+  # ---------- Schema builder (groups 2 and 4)
+
+  Scenario: Seven type tiles
+    Given the inspector of a field that can still change type
+    Then seven radio tiles are shown in this order, each with its icon, name and description
+      | tile      | icon        | description                                   |
+      | Text      | type        | Short text, like a title or a name            |
+      | Rich text | pilcrow     | Long text with formatting, written in Markdown |
+      | Number    | hash        | Whole or decimal numbers                      |
+      | Yes or no | toggle-left | An on or off switch                           |
+      | Date      | calendar    | A calendar day, without a time                |
+      | Choice    | list        | One option from a list you define             |
+      | Media     | image       | One image from your media library             |
+    And the grid has 3 columns in the desktop inspector and 2 in the mobile sheet
+
+  Scenario: Adding a media field (design "New media field, seven types")
+    Given Events with 7 saved fields and 37 entries
+    When the user activates "Add field", types the label "Thumbnail" and chooses the tile "Media"
+    Then the new row shows the badge "New", the key "thumbnail" (Auto, editable) with the help "The name used in the API. Starts with a letter. Lowercase letters, digits and underscores."
+    And the seven tiles are all enabled with Media selected and the legend "Type" has no lock
+    And the chip reads "Unsaved changes"
+    And the row is: grip, a 28 px square holding the image icon, the label, the key in mono and the badge "New"
+
+  Scenario: The inspector of a media field shows only what applies (design "Media field selected")
+    Given Events with a saved optional media field "Thumbnail" as its eighth field
+    When the user selects the row "Thumbnail"
+    Then the inspector reads "Field: Thumbnail" and holds, in this order, the Label input, the locked Key "thumbnail" with "Used in the API, so it can't change.", the Type tiles, the switch "Required" with "An entry can't be saved with this field empty." and the hint block
+    And the legend of the tiles reads "Type" with a lock and "Can't change after saving", Media is selected and the six other tiles are dimmed to 40 % and not selectable
+    And the hint block is info-soft with an info icon and reads "Holds one image from the media library. Entries link to the image instead of keeping a copy, so they always show its current version."
+    And "Unique values", "Default value", the limit inputs, the "Limits" heading and the choice list are not rendered at all
+
+  Scenario: Changing a new row to and from Media
+    Given a new row of type Text, required, with a Longest of 80
+    When the user chooses the tile "Media"
+    Then the label, the key and Required are kept and unique, default, limits and choices are reset
+    When the user then chooses the tile "Number"
+    Then the media hint is gone and the number controls show with no stale value
+
+  Scenario: A required media field (design "Media field, required")
+    Given a saved media field "Thumbnail" that is required
+    Then its row carries the existing Required marker "R" (accessible name "Required") next to the key
+    And its inspector shows Required switched on
+
+  Scenario: The PUT and POST body of a media field
+    Given a media field with the label "Thumbnail", the key "thumbnail" and Required off
+    When the type is saved
+    Then the field is sent as {"key":"thumbnail","label":"Thumbnail","type":"media","required":false,"unique":false,"default":null,"min":null,"max":null,"options":[]}
+    And a round trip of the loaded field to the payload produces no change
+
+  Scenario: Media in the API preview
+    Given the builder holds a media field "Thumbnail"
+    Then the sample entry shows "thumbnail": null and no "Example text"
+
+  Scenario: The mobile sheet of a media field
+    Given a 390 px viewport
+    When the user selects the row "Thumbnail"
+    Then the 92 % sheet titled "Field: Thumbnail" shows the same inspector in one column with the type tiles in 2 columns and the footer button "Done"
+
+  Scenario: The field-type gallery (group 4) has no SPA screen
+    Then the registry facts above are covered by the registry scenarios and no route renders the gallery frame
+
+  # ---------- Review (group 3)
+
+  Scenario: A required media field added to a type with entries is refused first (design "Review: required media field refused")
+    Given Events with 12 entries and a new media field "Thumbnail" that is required
+    When the user activates Save
+    Then no PUT is sent
+    And the dialog "Review changes to Events" with "Apply them to save the content type." opens (a bottom sheet on mobile)
+    And the summary reads "Add 1 field" and "Events has 12 entries. Each one is checked against the new fields when you apply."
+    And the row "Add Thumbnail" has the warning badge "Can't be applied" and the 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."
+    And the note "Back to editing keeps your other changes." shows instead of the "Flagged changes can be refused..." note
+    And "Back to editing" is enabled and "Apply changes" is disabled (aria-disabled), so pressing it sends nothing
+
+  Scenario: The refusal is only for a new required media field with entries
+    Given Events with <entries> entries and the edit <edit>
+    When the user activates Save
+    Then <result>
+
+    Examples:
+      | entries | edit                                                    | result                                                                                              |
+      | 12      | adds Thumbnail, Media, optional                         | the review opens, "Apply changes" is enabled                                                        |

+
+  Scenario Outline: The clean row (design "Review: optional media field")
+    Given Events with <entries> entries and a new optional media field "Thumbnail"
+    Then the row "Add Thumbnail" reads "<text>" with no flag
+    And "Apply changes" is enabled
+
+    Examples:
+      | entries | text                                       |
+      | 12      | Media, optional. 12 entries are unaffected. |
+      | 1       | Media, optional. 1 entry is unaffected. (proposed copy) |
+
+  Scenario: Back to editing after the refusal
+    Given the refused review is open
+    When the user chooses "Back to editing" (or presses Esc or the close icon)
+    Then the dialog closes, every edit is kept and no request was sent
+    When the user turns Required off on the new row and activates Save
+    Then the review opens with the clean row and "Apply changes" enabled
+
+  Scenario: The refusal follows offline and applying
+    Given the refused review is open
+    Then "Apply changes" stays disabled whatever the connection
+    And with a clean review, "Apply changes" is still disabled while offline, as before
+
+  Scenario: The server refuses anyway
+    Given the entry count was stale and the client opened no refusal
+    When the PUT answers 409 "schema_incompatible"
+    Then the existing "Nothing was changed" refusal flow of features/schema_builder_edit.feature runs unchanged
+
+  Scenario: 422 invalid_field on a media field
+    Given the PUT answers 422 "invalid_field"
+    Then the existing invalid-field failure of the builder is shown and the edits stay
+
+  # ---------- MediaFieldControl in the entry editor (group 6)
+
+  Scenario: Where the control sits
+    Given Events with the fields Title, Starts on, Ends on, Online, Capacity, Category, Description and Thumbnail
+    Then the control for Thumbnail is the eighth, after Description, full width in the 760 px column, and the footer lines come after it
+
+  Scenario: Empty, optional (design "Media control: empty, optional")
+    Given /content/events/new, or an entry whose thumbnail is null
+    Then the label reads "Thumbnail"
+    And a dashed box (1 px, border-accented, padding 12) holds a 40 px square with the image icon, the text "No image selected." and the outline button "Pick an image" with the image-plus icon
+    And the help line reads "One image from your library."
+    And on mobile the box stacks and the button is 44 px high
+
+  Scenario: Empty, required (design "Media control: empty, required")
+    Given the field is required
+    Then the label reads "Thumbnail *" with the asterisk hidden from assistive technology, and the rest is as the empty state
+
+  Scenario: Filled (design "Media control: filled")
+    Given an entry whose thumbnail is 7 and media.thumbnail is {"id":7,"filename":"lime-plaster-workshop.jpg","width":1600,"height":900,"size":245760,"thumbnail_url":"/media/lime-plaster-workshop.jpg"}
+    Then a solid 1 px box (border-accented, padding 12) holds a 160 × 120 thumbnail button showing thumbnail_url, the filename in weight 500, "1600 × 900 · 240 KB" in 12/18 muted, the outline button "Change image" (image icon) and the ghost button "Remove" (x icon)
+    And the help line reads "One image from your library."
+    And on mobile the thumbnail is full width at 16:9 and the two buttons are full width and 44 px high
+    And a width or height of null (a vector image) reads "Vector · 8 KB"
+
+  Scenario: Hover (design "Media control: hover")
+    Given the filled state on desktop
+    When the pointer is over the thumbnail
+    Then the box border takes the --ui-text-muted colour and a 28 px bar at the bottom of the thumbnail (--ui-bg-inverted, --ui-text-inverted) reads "Change image" with the image icon at 14 px
+    And mobile has no hover state and shows the filled state
+
+  Scenario: Focus (design "Media control: focus")
+    Given the filled state
+    When the keyboard focus reaches the thumbnail button
+    Then it has a 2 px --ui-primary outline with a 2 px offset
+
+  Scenario: Pointer and keyboard open the picker
+    Given the filled state
+    When the user activates the thumbnail, "Change image", or on an empty control "Pick an image"
+    Then the picker opens in field mode and nothing else changes
+
+  Scenario: Remove
+    Given the filled state
+    When the user activates "Remove"
+    Then the value becomes null, the control shows the empty state and the chip reads "Unsaved changes"
+    And the live region says "Image removed from Thumbnail." and the focus is on "Pick an image"
+
+  Scenario: Missing image, optional (design "Media control: image no longer in the library")
+    Given media.thumbnail is {"id":7,"missing":true} and the field is optional
+    Then the box is solid with a dashed 160 × 120 placeholder (16:9 on mobile) holding image-off at 24 px, with role "img" and the name "Image no longer in the library"
+    And beside it "This image is no longer in the library" in weight 500, the help "You can still save. The entry keeps the link until you change it." in 12/18 muted, the outline button "Choose another image" and the ghost button "Clear"
+    And there is no help line under the box
+    And "Save" is allowed and the data sent keeps thumbnail 7
+
+  Scenario: Clear
+    Given the missing state
+    When the user activates "Clear"
+    Then the value becomes null, the live region says "Thumbnail cleared." and the focus is on "Pick an image"
+
+  Scenario: Missing image, required (design "Media control: missing image, required")
+    Given media.thumbnail is {"id":7,"missing":true} and the field is required
+    Then the in-box help reads "Thumbnail is required. Choose another image to save."
+    And when the user saves, no request is sent, the box takes the error border, the line "Pick an image for Thumbnail." shows with a circle-alert icon, the chip reads "Not saved" and the focus is on "Choose another image"
+
+  Scenario: Validation error on an empty required field (design "Media control: validation error")
+    Given an empty required media field
+    When the user activates "Save"
+    Then no request is sent
+    And the box border is --ui-error with an inset 1 px --ui-error, the error line "Pick an image for Thumbnail." with circle-alert at 14 px replaces the help line, and the chip reads "Not saved"
+    And the focus moves to "Pick an image" and the page scrolls to it
+    And only the first field in schema order with an error takes the focus
+
+  Scenario: Picking clears the error
+    Given the validation error is shown
+    When the user picks an image
+    Then the error and the error border go, the chip reads "Unsaved changes" and nothing else is validated
+
+  Scenario: Saving (design "Media control: saving")
+    Given the PUT has not answered
+    Then the form is dimmed to 70 %, the thumbnail is at 60 %, the buttons take the disabled look, the thumbnail button and the buttons are not operable and the picker cannot open
+    And Save reads "Saving…"
+
+  Scenario: Read-only after a schema change (design "Media control: read-only, type changed")
+    Given the PUT answers 422 "invalid_entry: thumbnail: unknown_field" and thumbnail is a media field of the loaded type
+    Then a warning alert "The fields of Events changed" reads "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." with the action "Reload form"
+    And the control looks as in Saving and cannot be operated
+    And "Reload form" fetches the type and the entry again and rebuilds the form with the control from the answered media map
+    And any other key keeps the copy of features/content_entry_editor.feature state 12
+
+  Scenario Outline: What the control shows and sends
+    Given the loaded value <loaded> with media <media>
+    When the user <action> and activates "Save"
+    Then the control shows <shown>
+    And the data holds "thumbnail": <sent>
+
+    Examples:
+      | loaded | media                              | action                                  | shown                              | sent |
+      | null   | none                               | saves with nothing changed              | the empty state                    | null |
+      | 7      | existing image 7                   | saves with nothing changed              | the filled state                   | 7    |
+      | 7      | missing image 7 (optional)         | saves with nothing changed              | the missing state                  | 7    |
+      | 7      | existing image 7                   | picks image 8                           | image 8 (its own library data)     | 8    |
+      | 7      | existing image 7                   | activates Remove                        | the empty state                    | null |
+      | 7      | missing image 7                    | activates Clear                         | the empty state                    | null |
+      | null   | none                               | picks image 8                           | image 8                            | 8    |
+
+  Scenario: Right after a pick the control uses the picked library item
+    Given the user picks "bathroom-tiles.png" (id 8, 800 × 600, 51200 bytes) from the library
+    Then before any save the control shows its filename, "800 × 600 · 50 KB" and its url as the thumbnail
+    And no request is made for it
+    When the PUT answers 200 with media.thumbnail for image 8
+    Then the control is rebuilt from the answered media map
+
+  Scenario: Dirty tracking of a media value
+    Given an entry whose thumbnail is 7
+    When the user picks image 8 then picks image 7 again
+    Then the chip reads "Saved", "Save" is disabled and the leave guard does not prompt
+    When the user picks image 8
+    Then the chip reads "Unsaved changes" and the leave guard prompts
+
+  Scenario Outline: Server answers for a media field
+    Given the client found no error and the PUT or POST is sent
+    When the server answers <status> "<body>"
+    Then <result>
+
+    Examples:
+      | status | body                              | result                                                                                                                       |
+      | 422    | invalid_entry: thumbnail: required| "Pick an image for Thumbnail." under the control, error border, chip "Not saved", focus on the first button                   |
+      | 422    | invalid_entry: thumbnail: type    | "Thumbnail must be an image from the library." under the control, chip "Not saved", focus on "Change image" or "Pick an image" (the image was deleted between the pick and the save) |
+      | 409    | schema_incompatible               | not an entry answer; never produced by the entry routes                                                                       |
+
+  Scenario: Create payload with a media field
+    Given /content/events/new with Title "Open day", Starts on 2026-11-21 and the media field left empty
+    When the user activates "Save"
+    Then POST /v1/content-type/events/entry is sent once with "thumbnail": null among the other keys, never absent
+    And with image 8 picked it holds "thumbnail": 8, a JSON number
+
+  Scenario: The title of an entry whose first field is media
+    Given a type whose first field is a media field
+    Then the page title, the breadcrumb and the saved toast read "Entry 42" (an id is not a title) and the list card title reads the same (proposed)
+
+  Scenario: Layout of the generated form with a media field
+    Given a boolean, a number or a date field before the media field
+    Then the media field never pairs and is full width at every viewport
+
+  # ---------- Picker in field mode (group 10)
+
+  Scenario: Opening the picker from an optional field (design "Library: nothing chosen")
+    Given the control holds image 1 "north-wall.jpg" and the field is optional
+    When the user activates "Change image"
+    Then the dialog (640 px wide on desktop, a bottom sheet on mobile) is titled "Choose an image" and has the tabs "Upload" and "Library", opening on Library
+    And the search reads "Search by filename"
+    And the first row of the Library tab is "No image" with "Leave this field empty."
+    And the summary reads "Newest first · 48 images", the tiles are square, 4 columns on desktop and 3 on mobile, and "Load more" shows
+    And the tile of image 1 carries the badge "Current" (sand fill, --rc-on-sand text, 18 px high, bottom left)
+    And "Cancel" is enabled and "Use this image" is disabled (aria-disabled)
+    And there is no alt text field, no variant select, and no request to /v1/image-variants
+
+  Scenario: Choosing an image (design "Library: image chosen")
+    When the user selects a tile
+    Then it gets the primary outline with a check at top right, aria-pressed is true, and a strip appears below the grid with a 56 px thumbnail, the filename and "dimensions · size"
+    And the grid shrinks and "Load more" is hidden while a tile is selected, as in the article picker
+    And "Use this image" is enabled
+    When the user activates it
+    Then the dialog closes, the value becomes that image's id, the control shows its data, the live region says "Image selected: <filename>" and the focus is on "Change image"
+
+  Scenario: Choosing "No image" (design "Library: No image chosen")
+    When the user selects the row "No image"
+    Then it takes the sand fill, the primary border and a check, with aria-pressed true, and any selected tile is released
+    And the primary button reads "Remove image"
+    When the user activates it
+    Then the value becomes null, the live region says "Image removed from Thumbnail." and the focus is on "Pick an image"
+
+  Scenario: A required field has no "No image" row (design "Library: required field")
+    Given the field is required
+    Then the Library tab shows no "No image" row and the title is still "Choose an image"
+
+  Scenario: Choosing the current image again
+    Given the control holds image 1
+    When the user selects the tile "Current" and activates "Use this image"
+    Then the dialog closes, the value does not change, the chip stays as it was, and no announcement is made (proposed)
+
+  Scenario: Empty library (design "Library: empty")
+    Given GET /v1/media/ returns no image
+    Then the picker opens on the Upload tab unless the user already chose a tab, and the Library tab reads "Your library is empty" / "Images you upload appear here, ready to use in any article or entry." with "Upload an image"
+    And "Upload an image" switches to the Upload tab
+    And the article picker keeps "Images you upload appear here, ready to use in any article."
+
+  Scenario Outline: Library failures (design "Library: failed to load")
+    Given GET /v1/media/ answers <outcome>
+    Then <result>
+
+    Examples:
+      | outcome         | result                                                                                                                         |
+      | 500             | the error alert "Couldn't load your library" / "Check your connection and try again." with "Try again", no "No image" row       |
+      | a network error | the same                                                                                                                       |
+      | 429             | the countdown alert of the Media page                                                                                          |
+      | 401             | the global redirect, no local copy                                                                                             |
+
+  Scenario: Try again
+    Given the failed state
+    When the user activates "Try again"
+    Then only GET /v1/media/ is sent again and the grid replaces the alert
+
+  Scenario: Loading (design "Library: loading")
+    Given GET /v1/media/ has not answered
+    Then after 150 ms skeleton tiles show (8 on desktop, 9 on mobile), no "No image" row shows and "Use this image" is disabled
+
+  Scenario: Search and no results
+    When the user types "wall"
+    Then the search is trimmed and debounced, the selection is released and the grid reloads
+    And an empty match reads "No images match \"wall\"" with "Clear search", as in the article picker
+
+  Scenario: Load more
+    When the user activates "Load more"
+    Then the next page loads, the focus stays on the button until the new tiles arrive and then moves to the first new tile
+
+  Scenario: Upload tab (design "Upload tab")
+    When the user opens the Upload tab
+    Then the existing flow runs unchanged: "Drop an image here, or choose a file", "PNG, JPEG, WEBP, SVG · max 10 MB", crop and resize, the duplicate check "Already in your library" with "Use existing" and "Upload anyway"
+    And a finished upload lands in the library and becomes the value of the field, as in the Sites and Authors pickers, then the dialog closes and the live region says "Image selected: <filename>" (to confirm, decision D5)
+
+  Scenario Outline: Upload failures keep the existing copy
+    Given the POST /v1/media/ answers <outcome>
+    Then <copy> shows and nothing is chosen
+
+    Examples:
+      | outcome         | copy                                                              |
+      | 413             | That file is too large.                                           |
+      | 400             | That request wasn't valid. Check the fields and try again.        |
+      | 429             | Too many requests. Try again in a few minutes.                    |
+      | 500             | Something went wrong on our side. Nothing was changed. Try again in a moment. |
+
+  Scenario: Cancel and Escape
+    When the user activates "Cancel" or presses Esc or the close icon
+    Then nothing changes and the focus returns to the button that opened the picker
+
+  Scenario: Tile names in field mode
+    Then each tile is a button named "stone-steps.jpg, 310 KB" and "stone-steps.jpg, 310 KB, Current" for the current image, with aria-pressed, and no "used in" part
+    And "No image" is a button with aria-pressed and "Use this image" uses aria-disabled while nothing is chosen
+
+  Scenario: The other pickers are unchanged
+    Then the article picker still reads "Add an image", "Insert image", "In this article", the alt text and the variant select
+    And the Sites, Authors and SEO pickers still read "Use image" with no strip and no "No image" row
+
+  # ---------- Entry list (group 5), minimal safe cell
+
+  Scenario: The Thumbnail column (design "Thumbnail column")
+    Given Events with a Thumbnail media field, the columns Title, Thumbnail, Starts on and Category chosen, and the items 42 and 41 with an existing image, 40 and 37 with null, 39 with a missing image
+    Then the header reads "Thumbnail" with no sort icon and no aria-sort, in a column 80 px wide
+    And an existing image shows a 40 px square thumbnail from media.thumbnail_url, with 4 px above and below, so the row stays 48 px
+    And a null value shows "–" in the muted colour
+    And a missing image shows a dashed 40 px square with the unlink icon, role "img" and the name "Image no longer in the library"
+    And the thumbnail is read from the item's own "media" object, with no extra request
+
+  Scenario: Tooltip of the missing placeholder
+    Given a missing image in the list on desktop
+    When the pointer or the focus reaches the dashed square
+    Then a tooltip reads "Image no longer in the library"
+    And mobile has no tooltip
+
+  Scenario: The mobile card (design "Thumbnail column", mobile)
+    Given a 390 px viewport and the Thumbnail column chosen
+    Then a 32 px thumbnail leads each card, "–" stands for none, a dashed 32 px square for a missing image, and the card keeps its 68 px minimum height
+    And when no media field is among the chosen columns the card is unchanged
+
+  Scenario: Columns menu (design "Columns menu with Thumbnail")
+    When the user opens "Columns"
+    Then "Thumbnail" is listed with the image icon, its key "thumbnail", and a checkbox like the other fields
+    And the summary reads "4 of 6" and on mobile "Choose up to 6 fields to show. 4 selected."
+    And the cap of 6, Reset and the stored choice work as for any field
+
+  Scenario: Thumbnail as the first column
+    Given a type whose first field is a media field
+    Then the first column still links to the editor and the thumbnail is the link content
+
+  Scenario: Plain text of a media cell
+    Given the card or a title needs the text of a media cell
+    Then it reads "–" for none and never the numeric id
+
+  # ---------- Accessibility (media-field-changes.md section 6)
+
+  Scenario: Accessibility of the control
+    Then the control is role="group" labelled by the field label
+    And the main button (Pick an image, or Change image) carries aria-required when the field is required
+    And the accessible names are "Pick an image for Thumbnail", "Change image, lime-plaster-workshop.jpg, 1600 by 900, 240 KB" (the thumbnail), "Remove image from Thumbnail", "Clear Thumbnail" and, for the placeholder, role "img" "Image no longer in the library"
+    And the error text has an id, and the main button gets aria-invalid="true" and aria-describedby with the error id then the help id
+    And the tab order is label, thumbnail, Change image, Remove, then help or error (two stops open the same picker, as drawn; decision D8)
+    And one polite live region announces "Image selected: lime-plaster-workshop.jpg", "Image removed from Thumbnail." and "Thumbnail cleared."; nothing is announced when the picker opens
+    And focus goes to the first invalid control on a refused save and, after the picker, to the places of the picker scenarios
+    And mobile targets are 44 px and there is no hover on mobile

+# QA: Media field type in the SPA (slice B)
+
+Runner: Vitest + Vue Test Utils (`task test:web`). No Go test: the backend is covered by features/media_field_type.qa.md and nothing changes in it. Kit: extend `views/__tests__/schemaTestKit.ts` with the Events type (7 fields, plus Thumbnail as the 8th, optional or required, saved or new), entries whose `data.thumbnail` and top-level `media` vary, the library list (`GET /v1/media/?page=&size=&q=` with `items`, `total`, `counts`), and the plain-text bodies `invalid_entry: thumbnail: required`, `invalid_entry: thumbnail: type`, `invalid_entry: thumbnail: unknown_field`, `schema_incompatible`, `invalid_field`. Library fixtures: 1 "north-wall.jpg", 7 "lime-plaster-workshop.jpg" (1600 × 900, 245760 bytes, shown "240 KB"), 8 "bathroom-tiles.png" (800 × 600, 51200 bytes, "50 KB"), a vector image with null width and height. Pin the time zone; never freeze the system date. No state of this slice depends on the clock.
+
+## Automated
+
+Registry and pure logic (lib/__tests__, it.each over the feature's Examples):
+1. Registry `media`: label, description, icon, control, no pairing, empty value, initial on create and edit, no unique, limits, default or choices, counter none, help, cell, API preview sample null. A loaded field of type `media` never resolves to the `text` fallback in the builder, the form or the list. The six existing types still pass every existing registry assertion unchanged (update the count assertions from six to seven).
+2. Validation table: required and optional with null, undefined, 7, 0, -1, 7.5, "7", true, 4294967296. A required field whose image is missing is `required` (registry takes the image summary, or the form passes it).
+3. Messages for required and type with the label "Thumbnail"; min, max, options and unique are never produced.
+4. Payload: id to id, null to null, an optional missing stored id is sent unchanged, never absent. The builder payload of a media field equals `{key,label,type:'media',required,unique:false,default:null,min:null,max:null,options:[]}`; a loaded media field round-trips with no diff.
+5. Builder model: `changeFieldType` to and from media resets unique, default, limits and options and keeps label, key and required. Sample preview value is null.
+6. Review diff: the add row of a media field, required with total > 0 is flagged "Can't be applied" with the exact text; optional reads "Media, optional. N entries are unaffected." (plural rule for 1); total 0 gives no review; making a saved media field required stays "Now required." with "Entries may not fit". Summary line is unchanged.
+7. Entry helpers: `entryTitle` with a media first field gives "Entry N"; `describeCell` and `plainCellText` give "–" for none and never the id; media summary parsing for existing, missing and absent keys; `formatDimensions` and `formatSize` give "1600 × 900" and "240 KB" for 245760 bytes and "Vector" for null dimensions.
+
+Schema builder (views/__tests__/SchemaBuilderMedia*.spec.ts):
+8. Seven tiles in order with icon, name and description; 3 columns in the desktop inspector, 2 in the sheet.
+9. New media field: "New" badge, key editable with its help, seven tiles enabled, chip "Unsaved changes".
+10. Saved media field: key locked with its help, legend lock and "Can't change after saving", six tiles dimmed and unselectable, hint block copy, Required switch and copy, and that "Unique values", "Default value", limit inputs, "Limits" heading and choice list are absent from the DOM.
+11. Required marker on the row; row anatomy (28 px image square, label, key, badges).
+12. Mobile sheet: title "Field: Thumbnail", footer "Done", one column.
+13. Save paths: PUT and POST bodies; 422 invalid_field and 409 schema_incompatible keep their existing flows.
+
+Review (views/__tests__/SchemaBuilderMediaReview.spec.ts):
+14. Refusal: dialog copy, summary, row, badge, note "Back to editing keeps your other changes.", Apply `aria-disabled` and a click sends no PUT; Back to editing, Esc and close keep the edits and send nothing; turning Required off then Save shows the clean row with Apply enabled.
+15. The table of the feature (entries 12 and 0, optional and required, changed to required, mixed with a Capacity change); Apply stays disabled offline in both reviews.
+16. A stale count: PUT 409 `schema_incompatible` runs the existing refusal flow.
+
+MediaFieldControl (components/__tests__/MediaFieldControl.spec.ts), one test per state and viewport (components/__tests__/viewport.ts for 1440 and 390):
+17. Empty optional and required: structure, copy, " *" hidden from AT, help line, 44 px button on mobile.
+18. Filled: thumbnail 160 × 120 (full width 16:9 on mobile), filename, "1600 × 900 · 240 KB", buttons and icons, help line; vector image reads "Vector".
+19. Hover bar on desktop only (`pointerenter` on the thumbnail), absent on mobile; focus ring classes on the keyboard-focused thumbnail.
+20. Error: border classes, error line replaces help, aria-invalid and aria-describedby order (error id, help id), focus on "Pick an image" or "Choose another image".
+21. Missing optional and required: placeholder role img and name, copy, no help line under the box, buttons.
+22. Saving and read-only: form 70 %, thumbnail 60 %, buttons disabled, picker cannot open.
+23. Events: emits `update:modelValue` with the id or null for pick, "Remove image" choice, Remove and Clear; announcements in one polite live region; focus targets after Use this image (Change image), Remove, Clear and "Remove image" (Pick an image), and after Cancel and Esc (the opener).
+24. Names and role: group labelled by the label, the exact accessible names, aria-required on the main button, two tab stops as drawn.
+
+Entry editor (views/__tests__/EntryEditorMedia*.spec.ts):
+25. Position after Description, full width, never pairs; form built from the type with Thumbnail.
+26. The table "What the control shows and sends" (it.each): loaded value and media map to shown state and PUT body.
+27. After a pick the control shows the picked library item's data with no request; after the PUT it is rebuilt from the answered `media`; after "Reload form" from the refetched entry.
+28. Dirty tracking: pick 8 then 7 is clean; pick 8 is dirty and the leave guard prompts.
+29. Client validation: required empty and required missing give no request, "Not saved" chip, focus and scroll on the first error in schema order; picking clears the error; optional missing saves with the id unchanged.
+30. Server answers: 422 required and type map to the control with their messages and focus; 422 `unknown_field` on a media key shows the "The Thumbnail field was changed..." line, other keys keep the state 12 copy of features/content_entry_editor.feature; create payload `thumbnail: null` and `thumbnail: 8`.
+31. Title of an entry whose first field is media: "Entry N" in title, breadcrumb, toast and list card.
+
+Picker field mode (components/__tests__/ImageUploaderField.spec.ts, views/__tests__/EntryEditorPicker.spec.ts):
+32. Title, tabs, search, "No image" row on optional only and never on required, empty, error and loading states; "Current" badge replaces "In this article"; tile names with and without ", Current"; aria-pressed on tiles and on "No image"; no alt field, no variant select, and no `/v1/image-variants` request.
+33. Selection: strip with 56 px thumbnail, filename and "dimensions · size"; Load more hidden while selected; "Use this image" `aria-disabled` until a choice; "Remove image" when No image is chosen; selecting a tile releases No image and the reverse; selecting the Current tile then Use closes with no change and no announcement.
+34. Library states: empty (field copy with "or entry", and the article copy unchanged), 500 and network failure with Try again repeating only GET /v1/media/, 429 countdown alert, 401 global, loading skeleton after 150 ms (8 and 9 tiles), search trimmed and debounced, no results, Load more focus move.
+35. Upload tab: unchanged flow including the duplicate card; a finished upload becomes the field value (per decision D5) and announces "Image selected: ..."; the four upload failure copies.
+36. Dialog 640 px wide on desktop, bottom sheet on mobile; Cancel, Esc and close return focus to the opener.
+37. Regression: the article picker and the Sites, Authors and SEO pickers keep their copy and behavior (run their existing specs unchanged; if one needs an edit, stop and report).
+
+Entry list (components/__tests__/FieldCell.spec.ts, EntryTable, EntryCardList, ColumnPicker):
+38. Thumbnail, "–" and missing cells: size 40 px, 4 px margins, row height 48 px, role img and name on the placeholder, tooltip on desktop only, `alt` of the thumbnail (proposed: the filename).
+39. Header "Thumbnail": no sort icon, no `aria-sort`, 80 px; mobile card with a 32 px leading thumbnail and the 68 px minimum height, unchanged when no media column is chosen.
+40. Columns menu: Thumbnail listed with the image icon and its key; "4 of 6" and the cap behaviour; stored choice in localStorage.
+41. No extra request for thumbnails; a first media column still links to the editor.
+
+Cross-cutting:
+42. French: every new string has an entry (the i18n completeness spec passes, including the files added to the list in `i18n/contentMessages.spec.ts` if any).
+43. Existing specs that assert six types or six tiles are updated to seven and nothing else in them changes.
+
+## Visual (task visual:check)
+
+Prerequisites in web/visual, no change under docs/design:
+- `check.ts`: states of the board groups 5 and 6 that the design markdown does not list (`Thumbnail column`, `Columns menu with Thumbnail`, `Missing image: tooltip`; the ten `Media control: ...` states) must be added to the screens `content` and `entry`. Today `extraSources` entries whose group equals the screen's primary group are dropped (decision D3), so the runner must be changed to merge them. Groups 2 and 3 (screen `schema`) and group "10 Media picker for fields" (add to `extraSources.entry`, board RenewCMS Screens Schema.dc.html) are plain `extraSources` additions. Group 4 "Media" is a reference gallery with no SPA route: no setup, covered by Vitest. Group 1 "Custom type: read-only view" and group 11 are slice C.
+- `states.ts`: Events gets an eighth field Thumbnail (media) in `schemaEventsFields` variants for these states only, so existing states keep their 7 fields. Image URLs (`thumbnail_url`, library `url`) are fulfilled by the setup with an SVG stand-in drawing the board's placeholder (repeating-linear-gradient 135deg between --ui-bg-elevated and --ui-bg-accented, mono label "1600 × 900"), as `stubBoardImage` does for the picker. The media size is 245760 bytes so `formatSize` prints "240 KB". Sidebar calls stay mocked. Every capture within 10 %, desktop and mobile, light and dark.

+
+Board caveats to report, never hide:
+- The group 6 media states draw the form with a negative margin (-380 px desktop, -560 px mobile) under an intact title row inside an overflow-hidden box. A real page can only scroll as a whole, so the title row and topbar will differ. If a capture exceeds 10 %, an exception needs the user's explicit approval (`approvedBy`), as for existing schema states. Do not call `schemaSettle` after scrolling to the control, since it resets scrollTop.
+- Group 10 draws a stand-in entry form behind the dialog (design conflict 13), not the real editor. Expect a possible exception request for the page behind the dialog.
+- The frame and the copy list disagree on "Library: image chosen" (see above) and on the list row titles of "Thumbnail column"; the frame wins.
+- Group 6 "Saved" is not checked here; the existing entry setups are untouched.
+
+## Manual
+
+- Real backend, owner and a second verified user: create a type with a required Title and an optional Thumbnail; add an entry with an image; the thumbnail shows in the editor and in the list; change the image; remove it; save.
+- Delete the image from the Media page, reload the entry: the missing state, then save with the optional field kept (the id is sent unchanged); make the field required through a type with no entries and see "Pick an image for Thumbnail." on save.
+- Add a required Thumbnail to a type with entries: the review refuses with Apply disabled; make it optional and apply (real PUT 200). Make an existing optional media field required while an entry has none: real 409, then the existing refusal flow.
+- Upload from the Upload tab of the picker with crop and resize, and an already-in-library duplicate; confirm the final selection behaves as decided in D5.
+- Keyboard: tab order across the control (thumbnail, Change image, Remove), Enter and Space on a tile, Esc and Cancel return focus to the opener, focus after Use this image, Remove and Clear; screen reader announcements of the live region and of the error; contrast of the Current badge and the hover bar in light and dark.
+- Mobile: bottom sheet, 44 px targets, no hover.

+Feature: Media field type for custom content types
+
+  As a site owner or admin
+  I want a content type field that holds one image from the media library
+  So that entries link to the library image instead of keeping a copy
+
+  Background:
+    Given internal/domain/contenttype adds the field type "media" next to text, richtext, number, boolean, date and select
+    And a media field accepts only label, key and required; unique, default, min, max and options are refused with ErrInvalidField
+    And a stored media value is the id of a library image (uint32, at least 1) or null
+    And the entry rules required and type apply to a media field; min, max, options and unique never apply
+    And entry.Validate stays pure; the check that an image exists in the library is done by CreateEntry and UpdateEntry through the domain image.Repository
+    And CreateEntry, UpdateEntry, GetEntry and ListEntries receive image.Repository, wired only in api/dependecyInjection.go
+    And a changed value means a value that is not equal to the id the entry holds in the stored document for that key; on POST every non-null value is changed; on PUT the value is unchanged only when the id equals the stored one
+    And a changed or new non-null value must be an existing library image, else 422 "invalid_entry: <key>: type"
+    And an unchanged stored id whose image was deleted since passes the type check
+    And a required media field is never saved empty: null or absent gives 422 "invalid_entry: <key>: required", and so does an unchanged stored id whose image no longer exists
+    And rules are checked in field order for Validate, then library existence in field order, then unique, and the body names one field per answer
+    And an entry response keeps its seven keys (id, content_type, data, created_by, updated_by, created_at, updated_at) and adds the key "media"
+    And data keeps the image id (or null) as the value of each media field
+    And "media" is a JSON object keyed by media field key, always present ({} when the type has no media field or every media value is null)
+    And "media"[key] is {"id","filename","width","height","size","thumbnail_url"} for an existing image, with width and height null when unknown, or {"id","missing":true} when the image is gone
+    And thumbnail_url is the image's original path, the same value as the url of a media list item
+    And the same "media" object is on POST 201, PUT 200, GET one and every item of the list
+    And usage in the library means distinct articles, authors, sites and entries; one entry counts once however many of its media fields point at the image
+    And GET /v1/media/ and GET /v1/media/{id} items carry used_in = articles + authors + sites + entries, and the counts.unused filter counts entries as uses
+    And GET /v1/media/{id}/usage stays a JSON array and gains items of type "entry"
+    And an entry usage item is {"type":"entry","id":<entry id>,"fields":[<media field keys>],"content_type_key":"event","content_type_name":"Events","first_field":{"key":<key>,"type":<field type>,"value":<raw stored value or null>}}, with no "title" and no "published"
+    And first_field is the first field of the type in schema order and its value is the raw stored JSON value, never formatted or truncated by the server; the client formats it with the same rule as the entry list and shows "Entry N" for null
+    And article, author and site usage items are unchanged and keep their "title"
+    And usage items are ordered articles by id, authors, sites, then entries by content type name then entry id; the array has no cap and the client shows the first few and the total
+    And the media routes keep their access rules and their plain-text errors (404 image_not_found, 400 uint32 format)
+    And DELETE /v1/media/{id} stays allowed for an image used by entries and leaves their data untouched
+    And MergeMedia (including the purge run) repoints entry media values from every merged copy to the kept image and reports it in the existing counts
+    And no repository method is added: entries that reference an image are found with contenttype.Repository.List and entry.Repository.ListPage (Unpaged), filtered in Go, so the code works on SQLite, MySQL/MariaDB and PostgreSQL with no JSON operators
+    And schema compatibility does not consult the library
+    And the key set assertions of the earlier custom content type and entry features and tests are amended from seven keys to eight
+    And types: the library images are 7 "lime-plaster.jpg" 1600x900 240000 bytes, 8 "bathroom-tiles.png" 800x600 51200 bytes; the type "event" has title (text, required) then thumbnail (media, label "Thumbnail", optional)
+    And users: admin id 2 (verified) can write types; any verified user can write entries
+
+  Scenario: Creating a content type with a media field
+    Given a valid jwt cookie for admin 2
+    When the client sends POST /v1/content-type with fields title (text, required) and {"key":"thumbnail","label":"Thumbnail","type":"media","required":false,"unique":false,"default":null,"min":null,"max":null,"options":[]}
+    Then the response status is 201
+    And the thumbnail field comes back with type "media", unique false, default null, min null, max null and options []
+
+  Scenario Outline: A media field refuses options it can't have
+    Given a valid jwt cookie for admin 2
+    When the client sends POST /v1/content-type with a media field that has <option>
+    Then the response status is 422
+    And the response body is "invalid_field"
+    And no content type is stored
+
+    Examples:
+      | option          |
+      | unique true     |
+      | default 7       |
+      | default "lime"  |
+      | min 1           |
+      | max 5           |
+      | options ["a"]   |
+
+  Scenario: The type of a saved media field never changes
+    Given the type "event" has an entry and a saved media field "thumbnail"
+    When admin 2 sends PUT /v1/content-type/event turning "thumbnail" into a text field
+    Then the response status is 422 with invalid_field and the schema is unchanged
+    When admin 2 sends PUT turning the text field "title" into a media field
+    Then the response status is 422 with invalid_field and the schema is unchanged
+
+  Scenario Outline: Adding a media field to a type that has entries
+    Given the type "event" has 12 entries
+    When admin 2 sends PUT /v1/content-type/event adding a media field "thumbnail" that is <required>
+    Then the response status is <status>
+    And the response body is <message>
+    And the stored schema is <outcome>
+
+    Examples:
+      | required | status | message             | outcome   |
+      | required | 409    | schema_incompatible | unchanged |
+      | optional | 200    |                     | updated   |
+
+  Scenario: Making a media field required
+    Given the type "event" has a saved optional media field "thumbnail", one entry with image 7 and one entry with null
+    When admin 2 sends PUT making "thumbnail" required
+    Then the response status is 409 with schema_incompatible
+    When the entry holding null is deleted and the PUT is sent again
+    Then the response status is 200
+
+  Scenario: Making a media field required while a stored image is gone
+    Given the type "event" has a saved optional media field "thumbnail" and one entry holding the id of a deleted image
+    When admin 2 sends PUT making "thumbnail" required
+    Then the response status is 200
+
+  Scenario: Creating an entry with an image
+    Given a valid jwt cookie for admin 2
+    When the client sends POST /v1/content-type/event/entry with {"data":{"title":"Lime plaster workshop","thumbnail":7}}
+    Then the response status is 201
+    And data.thumbnail is 7
+    And media is {"thumbnail":{"id":7,"filename":"lime-plaster.jpg","width":1600,"height":900,"size":240000,"thumbnail_url":"<the image path>"}}
+
+  Scenario Outline: An empty optional media field
+    When the client sends POST /v1/content-type/event/entry with <data>
+    Then the response status is 201
+    And data.thumbnail is <stored>
+    And media is {}
+
+    Examples:
+      | data                                    | stored |
+      | {"data":{"title":"A","thumbnail":null}} | null   |
+      | {"data":{"title":"A"}}                  | absent |
+
+  Scenario Outline: Entry values that break a media field are refused and store nothing
+    Given the type "event" has a media field "thumbnail" that is <required>
+    When the client sends POST /v1/content-type/event/entry with <data>
+    Then the response status is 422
+    And the response body is <message>
+    And no entry exists
+
+    Examples:
+      | required | data                                          | message                            |

+      | optional | {"data":{"title":"A","thumbnail":[7]}}        | invalid_entry: thumbnail: type     |
+
+  Scenario: Replacing the image of an entry
+    Given the entry 5 of type "event" holds thumbnail 7
+    When a verified user sends PUT .../entry/5 with {"data":{"title":"Lime plaster workshop","thumbnail":8}}
+    Then the response status is 200, data.thumbnail is 8 and media.thumbnail.filename is "bathroom-tiles.png"
+    When the user sends PUT with thumbnail null on an optional field
+    Then data.thumbnail is null and media is {}
+
+  Scenario: An image deleted after the entry was saved
+    Given the entry 5 holds thumbnail 7
+    When DELETE /v1/media/7 answers 204
+    And the client sends GET /v1/content-type/event/entry/5
+    Then data.thumbnail is still 7
+    And media is {"thumbnail":{"id":7,"missing":true}}
+
+  Scenario: An unchanged id whose image is gone can still be saved when the field is optional
+    Given the entry 5 holds thumbnail 7 and the image 7 was deleted
+    When the user sends PUT .../entry/5 with a new title and thumbnail 7
+    Then the response status is 200 and data.thumbnail is 7
+    And media.thumbnail is {"id":7,"missing":true}
+
+  Scenario Outline: A changed value must exist even when the old one is gone
+    Given the entry 5 holds thumbnail 7 and the image 7 was deleted
+    When the user sends PUT .../entry/5 with thumbnail <value>
+    Then the response status is <status> and the body is <message>
+
+    Examples:
+      | value | status | message                        |
+      | 999   | 422    | invalid_entry: thumbnail: type |
+      | 8     | 200    |                                |
+      | null  | 200    |                                |
+
+  Scenario Outline: A required media field with a missing image can't be saved as is
+    Given the entry 5 of a type whose "thumbnail" is required holds thumbnail 7 and the image 7 was deleted
+    When the user sends PUT .../entry/5 with thumbnail <value>
+    Then the response status is <status> and the body is <message>
+    And the stored entry is <outcome>
+
+    Examples:
+      | value | status | message                            | outcome   |
+      | 7     | 422    | invalid_entry: thumbnail: required | unchanged |
+      | null  | 422    | invalid_entry: thumbnail: required | unchanged |
+      | 8     | 200    |                                    | updated   |
+
+  Scenario: A create always treats the value as changed
+    Given the image 7 was deleted
+    When the client sends POST with thumbnail 7
+    Then the response status is 422 with invalid_entry: thumbnail: type
+
+  Scenario: Two broken fields name only one
+    Given a body with a required field left empty and a media field pointing at a missing image
+    When the client sends POST
+    Then the response names one field, with the required and type rules of Validate checked before the library existence
+
+  Scenario: Entry list responses carry the media object per item
+    Given 3 entries: one with image 7, one with image 7 deleted, one with null
+    When the client sends GET /v1/content-type/event/entry
+    Then each item keeps its seven keys and adds "media"
+    And the items' media are one existing object, {"thumbnail":{"id":7,"missing":true}} and {}
+    And items, total, page and size are unchanged
+
+  Scenario: Types without a media field are not enriched
+    Given the type "recipe" has no media field
+    When the client sends GET on a recipe entry
+    Then the body has the seven existing keys and "media" is {}
+    And the image repository is not called
+
+  Scenario: Media list items count entries as uses
+    Given the image 8 is used by 3 entries (one of them through two media fields) and by no article, author or site
+    And the image 7 is used by 2 articles and 5 entries
+    When the client sends GET /v1/media/
+    Then item 8 has used_in 3 and item 7 has used_in 7
+    And GET /v1/media/8 has used_in 3
+    And ?filter=unused does not list 8 or 7, and counts.unused does not count them
+
+  Scenario: Usage of an image lists articles and entries
+    Given the image 7 is used by article 12 "Heat pumps" (cover) and by entries 41, 42 and 43 of "event" and entry 9 of "workshop"
+    When the client sends GET /v1/media/7/usage
+    Then the response status is 200 and the body is a JSON array
+    And the article item is {"type":"article","id":12,"title":"Heat pumps","published":true,"fields":["cover"]}
+    And the entry items follow in the order event 41, 42, 43, then workshop 9 (content type name, then id), each with exactly type, id, fields ["thumbnail"], content_type_key, content_type_name and first_field, and no title and no published
+    And a client counts the array for the total
+
+  Scenario Outline: The raw first field in usage
+    Given an entry whose first field "<key>" is of type <type> and holds <stored>
+    When the client reads the usage of an image the entry uses
+    Then the entry item first_field is {"key":"<key>","type":"<type>","value":<value>}
+    And no string is built by the server and the item has no "title" key
+
+    Examples:
+      | key       | type     | stored                    | value                     |
+      | title     | text     | "Lime plaster workshop"   | "Lime plaster workshop"   |
+      | body      | richtext | "\n\nFirst line\n\nSecond" | "\n\nFirst line\n\nSecond" |
+      | seats     | number   | 18                        | 18                        |
+      | category  | select   | "Talk"                    | "Talk"                    |
+      | online    | boolean  | false                     | false                     |
+      | starts_on | date     | "2026-11-21"              | "2026-11-21"              |
+      | title     | text     | null                      | null                      |
+      | title     | text     | the key absent            | null                      |
+      | cover     | media    | 7                         | 7                         |
+
+  Scenario: Usage of an unused or unknown image
+    When the client sends GET /v1/media/8/usage with no use
+    Then the body is []
+    When the client sends GET /v1/media/999/usage
+    Then the response status is 404 with apperr.ImageNotFoundErrorMessage
+    When the client sends GET /v1/media/abc/usage
+    Then the response status is 400 with apperr.IdUint32ErrorMessage
+
+  Scenario: Deleting an image used by entries is allowed
+    Given the image 7 is used by 5 entries and 2 articles
+    When the client sends DELETE /v1/media/7
+    Then the response status is 204
+    And the 2 articles lose the image reference as today
+    And the 5 entries still hold data.thumbnail 7 and are not modified (updated_at and updated_by unchanged)
+
+  Scenario: Merging duplicates repoints entry media
+    Given the images 7 and 9 share the same sha256 and entries 41 and 42 point at 9
+    When the client sends POST /v1/media/merge with keep_id 7 and merge_ids [9]
+    Then the response status is 200
+    And entries 41 and 42 hold thumbnail 7, with created_by, updated_by and updated_at unchanged
+    And image 9 no longer exists
+
+  Scenario: A failure while repointing entries stops the merge
+    Given the entry repository fails on the second Update
+    When the client sends POST /v1/media/merge
+    Then the response status is 500, the entries already repointed are restored, and no image is removed
+
+  Scenario: The purge plan counts entries as uses
+    Given the duplicate group 7, 9 where only 9 is used (by 1 entry)
+    When the purge preview and the purge run
+    Then 9 is the kept image and 7 is the merged copy
+
+  Scenario: Use case level
+    Given fake contenttype, entry and image repositories
+    Then entry.Validate returns an error satisfying errors.Is(err, entry.ErrInvalidEntry) with Key "thumbnail" and Rule "required" or "type" for the shapes above
+    And CreateEntry and UpdateEntry return the same for a missing library image and perform no Create or Update
+    And UpdateContentType returns contenttype.ErrSchemaIncompatible for a new required media field and does not call Update
+    And contenttype.ValidateFields returns contenttype.ErrInvalidField for a media field with unique, default, min, max or options

+# QA procedure: media field type (slice A, API only)
+
+Package: `test` (black-box). No live server, no real SQLite file, no real SMTP, no SPA.
+
+## Setup shared by every case
+1. Call `validator.InitValidator()` once per test.
+2. Reuse the fakes of the custom content type pair (`mockContentTypeRepo`, `mockEntryRepo`) and of the media tests (image, article, site, author, variant file, storage, recorder fakes). Name any new fake uniquely across the package, for example `mockMediaFieldImageRepo`. The image fake must expose `Get`, a `getCalls` counter and a `delete(id)` helper.
+3. `mockEntryRepo` needs no new method (no repository method is added). Give it an `updateCalls` counter and a `failUpdateOn(n)` switch for the merge compensation case.
+4. Build `NewHandler(...)` for the entry, content type and media handlers over use cases wired to the fakes (the entry use cases now take the image fake). Mount them on a fresh `chi.NewRouter()` mirroring api/router.go: `/v1/content-type` and `/v1/media`, with `jwtauth.Verifier`, `jwtauth.Authenticator` and a test `jwtauth.New("HS256", []byte("test-secret"), nil)`. Add `RequireOwnerOrAdmin` on the content type write routes. If `api.InitBackendRoutes` with a partial `*api.UseCases` works, prefer it.
+5. Seed users: admin 2 and a plain verified user. Seed images 7 "lime-plaster.jpg" (1600x900, 240000 bytes) and 8 "bathroom-tiles.png" (800x600, 51200 bytes), with distinct paths. Seed the type "event" (title text required, thumbnail media optional) and a variant with thumbnail required.
+6. Inject a fake clock so `updated_at` > `created_at`.
+7. Decode entry and list bodies into `map[string]any`; compare numbers as `float64`.
+
+## Schema
+8. POST a media field with the allowed shape -> 201; the field has type "media", unique false, default/min/max null, options [].
+9. Table of refused options (unique true, default 7, default "lime", min 1, max 5, options ["a"]) -> 422 `invalid_field`, repo empty. Assert separately that `default: null` is accepted.
+10. Type change in both directions on a type with entries -> 422 `invalid_field`, schema byte-identical. On a type with no entries the existing free type change still applies.
+11. Add a media field to a type with 12 entries: required -> 409 `schema_incompatible`, schema unchanged; optional -> 200, existing entries still readable and `media` is `{}`. Make an optional media field required: 409 while an entry holds null, 200 once none does. Making it required while an entry holds an id of a deleted image -> 200 (compatibility does not consult the library).
+
+## Entry writes
+12. POST with image 7 -> 201; `data.thumbnail` is 7 and `media.thumbnail` has exactly `id`, `filename`, `width`, `height`, `size`, `thumbnail_url`; the key set of the entry is the seven existing keys plus `media`.
+13. POST with null and with the key absent on an optional field -> 201, `media` is `{}` (assert JSON `{}`, not null).
+14. Refusal table (required: absent, null; any: 999, "7", 0, -1, 7.5, 4294967296, true, [7]): status 422, exact body `invalid_entry: thumbnail: <rule>`, `createCalls == 0`.
+15. PUT replace 7 -> 8: 200, filename "bathroom-tiles.png". PUT to null on optional: 200, `media` is `{}`.
+16. After `delete(7)` on the image fake: GET entry 5 -> `data.thumbnail` 7 and `media.thumbnail` equals `{"id":7,"missing":true}` (no other key). PUT with the same 7 on an optional field -> 200, still 7 and still missing. PUT 999 -> 422 type, PUT 8 or null -> 200.
+17. Required field, image 7 deleted: PUT 7 -> 422 `required`, PUT null -> 422 `required`, entry unchanged; PUT 8 -> 200.
+18. POST with a deleted id 7 -> 422 `type` (create is always a changed value).
+19. Ordering: a body with two bad fields names one only: Validate rules first in field order, then the existence check.
+
+## Reads
+20. List: 3 entries (existing image, deleted image, null) -> each item has the seven keys plus `media`; values as in the feature; `total`, `page` and `size` unchanged; `items` is `[]` for an empty type.
+21. A type without a media field: `media` is `{}` and `getCalls == 0` on the image fake. A list of 100 entries pointing at the same image calls `Get` at most once for that id.
+
+## Media library counts
+22. Seed: image 8 used by 3 entries (one through two media fields) and no other use; image 7 used by 2 articles and 5 entries. `GET /v1/media/` -> `used_in` 3 and 7; `GET /v1/media/8` -> 3; `?filter=unused` omits both; `counts.unused` excludes both; an image with no use is still counted unused.
+23. Unchanged existing cases: article, author and site usage counts and the unused counts still pass with no entries in the fake.
+
+## Usage endpoint
+24. Image 7 with article 12 (cover), entries 41, 42, 43 of "event" and entry 9 of "workshop": status 200, a JSON array, article item unchanged (keys type, id, title, published, fields). Entry items have exactly the keys `type`, `id`, `fields`, `content_type_key`, `content_type_name`, `first_field`, and no `title` and no `published`. Order: article, then event 41, 42, 43, then workshop 9.
+25. Raw first-field table (text, richtext with leading blank lines, number 18, select, boolean false, date, text null, key absent, media 7). Assert `first_field` is exactly `{key, type, value}` with the value byte-equal to the stored JSON (richtext unmodified, number as a JSON number, null as JSON `null`). Assert the entry item JSON has no `title` key.
+26. Unused image -> `[]`; unknown -> 404 `image_not_found` text; `abc` -> 400 `apperr.IdUint32ErrorMessage`.
+
+## Delete and merge
+27. DELETE /v1/media/7 used by 5 entries and 2 articles -> 204; articles cleared as before; the fake entry repo records no Update; the 5 entries are byte-identical.
+28. Merge keep 7, merge [9] with equal sha256 and two entries on 9 -> 200; the entries hold 7; `created_by`, `updated_by` and `updated_at` are unchanged; image 9 is gone. Entries pointing at other images are untouched.
+29. Merge with `failUpdateOn(2)` -> 500, the first repointed entry is restored to 9, no image deleted, articles/sites/authors repointing rolled back as today.
+30. Purge preview and run on a duplicate group where only the copy is used by an entry: the used copy is the kept one; the fingerprint changes accordingly.
+
+## Use case level (no HTTP)
+31. `contenttype.ValidateFields` -> `ErrInvalidField` for each refused option. `entry.Validate` rows -> `errors.Is(err, entry.ErrInvalidEntry)` with the right key and rule. `CreateEntry`/`UpdateEntry` with a missing library image -> same error and no write. `UpdateContentType` with a new required media field -> `ErrSchemaIncompatible`, no `Update`.
+
+## Existing tests to amend
+32. Amend the existing key-set assertions from seven to eight keys in the earlier custom content type and entry feature, spec and test files (decision: `media` is always present). The coder owns this.
+
+## Manual verification (not exercised by the Go tests)
+- Real SQLite, then MySQL/MariaDB and PostgreSQL via the driver tasks: create a type with a media field, upload an image, save an entry, delete the image, reload the entry and confirm the id stays and `media` is `{missing:true}`.
+- Merge duplicates with entries on a copy against real storage and confirm the entries repoint and the file is removed.
+- Time `GET /v1/media/` with 1,000 entries across a type with a media field (usage lookup loads the entries of such types).
+- The SPA (builder, editor control, picker, list cell, library badge and detail panel) is slices B and C and is not checked here.

+Feature: Media merge hardening: atomic merge, no lost entry edits, one entry scan per purge
+
+  As a site owner or admin
+  I want a duplicate merge to either fully happen or not happen at all
+  So that a failure halfway never leaves articles, sites, authors, entries or the library half merged
+
+  Background:
+    Given this slice is backend only: no route, request body, response body, status code, error text or audit payload changes
+    And internal/domain gains a unit-of-work port (package transaction): Transactor with Run(ctx, func(Repositories) error) error, and Repositories holding the article, site, author, entry and image repositories bound to the open transaction
+    And internal/domain/transaction imports only the stdlib and other internal/domain/* packages
+    And Run commits when the function returns nil and rolls everything back when it returns an error or panics, and returns that error unchanged
+    And the GORM adapter lives in internal/infrastructure/persistence, asserts var _ transaction.Transactor = &X{}, and is built only in api/dependecyInjection.go
+    And SQL in the adapter stays portable across SQLite, MySQL/MariaDB and PostgreSQL
+    And MergeMedia and RunPurge depend on transaction.Transactor and never on persistence, gorm or models
+    And MergeMedia keeps its order: validate, load copies, plan which articles contain a copy name, then inside one transaction re-read each planned article body, apply the replacement of the copy names by the kept name to that re-read body and UpdateBody it, articles RepointImage, sites RepointImage, authors RepointAvatar, entry repoint and image row delete per copy
+    And restoreBodies, the entry restore of entryMediaScanner and every logCompensation call of the merge are deleted; nothing compensates by hand any more
+    And the stored file, the variant cache files and the variant cache rows of a merged copy are removed only after the transaction committed, through image.Storage and the variant file repository
+    And a failure removing those files after the commit is written to the injected *log.Logger, never rolled back, never changes the response or the audit event
+    And the audit event media.merge and the audit event media.purge are recorded outside the transaction, with the same params as today
+    And entries are repointed from candidates found by one scan (contenttype.Repository.List then entry.Repository.ListPage with Unpaged, filtered in Go), and each candidate is re-read with entry.Repository.Get inside the transaction before it is written
+    And an entry repoint only changes the media values that still point at a merged copy in the re-read data, keeps every other value of the re-read data, and leaves created_by, updated_by, created_at and updated_at untouched
+    And a candidate that no longer exists at re-read time is skipped
+    And RunPurge and PreviewPurge scan entries once per run and once per preview into an index of image id to entries, shared by the usage counts and by every duplicate group; the index is built in the use case and no repository method is added
+    And RunPurge runs one transaction per duplicate group, so a failing group rolls back alone and the other groups still merge
+    And the replacement of a copy name inside an article body matches whole stored file names only, so a name that is a suffix of another name is not rewritten inside it
+    And the media-field walks (field-type loops, the required and type rule constants, the entry.InvalidField wrapper) are deduplicated into one place; this is a pure refactor and has no scenario of its own beyond "behaviour unchanged"
+    And MergeMediaResult, purge.RunResult, the merge response {"articles_updated","merged"} (plus sites_updated and authors_updated where the sites and authors features already report them) and the 409, 404, 400 and 500 answers are unchanged
+    And fixtures: images 7, 8 and 9 share sha256 A with stored names; image 2 and 3 share sha256 B; the type "event" has title (text, required) then thumbnail (media, optional); users: admin 2 (verified)
+
+  Rule: A merge is all-or-nothing
+
+    Scenario Outline: Any failing step leaves the library exactly as it was
+      Given images 7 and 9 share sha256 A and 7 is the kept one
+      And article 1 and article 2 contain the stored name of image 9 in their bodies, article 3 has image 9 as its cover
+      And site 1 uses image 9 as its default social image and author 4 uses image 9 as its avatar
+      And entries 41 and 42 of "event" hold thumbnail 9
+      And <failing step> is armed to fail
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then the response status is 500 and the body is "Internal server error"
+      And the bodies of articles 1 and 2 are byte-identical to before
+      And article 3 still has cover 9, site 1 still uses 9, author 4 still uses avatar 9
+      And entries 41 and 42 still hold thumbnail 9 with updated_at and updated_by unchanged
+      And images 7 and 9 both still exist
+      And image.Storage.Delete and the variant file repository Delete are never called
+      And one failed media.merge audit event is recorded
+
+      Examples:
+        | failing step                                    |
+        | the UpdateBody of the first article             |
+        | the UpdateBody of the second article            |
+        | the article repository RepointImage             |
+        | the site repository RepointImage                |
+        | the author repository RepointAvatar             |
+        | the entry repository Get of the second entry    |
+        | the entry repository Update of the second entry |
+        | the image repository Delete of image 9          |
+        | the commit of the transaction                   |
+
+    Scenario: The transaction cannot start
+      Given the transactor fails to begin
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then the response status is 500
+      And no repository other than the reads of the planning phase was called, and no file was touched
+
+    Scenario: Several copies roll back together
+      Given images 7, 8 and 9 share sha256 A and the image repository Delete fails for image 9 after image 8 was deleted
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [8, 9]}
+      Then the response status is 500
+      And image 8 exists again, image 9 exists and no article, site, author or entry changed
+
+    Scenario: A successful merge still does everything
+      Given the Background fixtures of the first scenario and no armed failure
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then the response status is 200 and the body is {"articles_updated": 3, "merged": 1} plus the existing sites_updated and authors_updated keys
+      And entries 41 and 42 hold thumbnail 7 with created_by, updated_by and updated_at unchanged
+      And image 9 is gone from the repository and its stored file is removed
+
+    Scenario: A validation or lookup error never opens a transaction
+      Given any of the existing 400, 404 or 409 merge requests
+      Then the transactor Run is not called
+
+    Scenario: A rollback leaves updated_at and updated_by of entries untouched
+      Given the entries 41 and 42 hold thumbnail 9 with known created_at, updated_at, created_by and updated_by
+      And the repoint of entry 42 fails
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then the response status is 500
+      And entries 41 and 42 are byte-identical to before, including updated_at and updated_by
+
+  Rule: Stored files are removed only after the commit
+
+    Scenario: Files are touched after the commit and never before
+      Given a merge of image 9 into image 7 that succeeds
+      Then image.Storage.Delete("<stored name of 9>") is called after the transaction committed
+      And the variant files of image 9 are removed after the commit
+      And at no time before the commit is a file or a variant cache row of image 9 removed
+
+    Scenario Outline: A file failure after the commit is logged, not rolled back
+      Given a merge of the copies 8 and 9 into image 7 where <file failure>
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [8, 9]}
+      Then the response status is 200 and the body is the same as without the failure
+      And images 8 and 9 are gone from the repository and the articles, sites, authors and entries stay repointed
+      And the removal of the other copy is still attempted
+      And the injected logger holds one line naming the stored name and the error
+      And the media.merge audit event is a success with the usual params
+
+      Examples:
+        | file failure                            |
+        | image.Storage.Delete fails for image 9  |
+        | the variant file purge of image 9 fails |
+
+    Scenario: A purge group with a file failure after the commit counts as purged
+      Given groups A and B are planned and image.Storage.Delete fails for a merged copy of group A
+      When the client sends POST /v1/media/purge with {}
+      Then the response status is 200 and the body has groups_purged 2 and failed_groups 0
+      And the merged count includes the copies of group A
+      And the injected logger holds the file failure
+
+  Rule: A concurrent entry edit survives a merge
+
+    Scenario: An edit made after the scan is kept
+      Given entry 41 of "event" is {"title": "Workshop", "thumbnail": 9}
+      And the entry repository changes entry 41 to {"title": "Workshop 2026", "thumbnail": 9}, with a new updated_at and updated_by, right after the scan returns it
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then the response status is 200
+      And entry 41 is {"title": "Workshop 2026", "thumbnail": 7}
+      And its updated_at and updated_by are the ones of the concurrent edit, not older ones
+
+    Scenario: A concurrent edit that moved the entry off the merged copy is not overwritten
+      Given entry 41 holds thumbnail 9 when scanned
+      And the entry repository changes entry 41 to thumbnail 8 right after the scan returns it
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then entry 41 still holds thumbnail 8
+      And the entry repository Update is not called for entry 41
+
+    Scenario: An entry deleted after the scan is skipped
+      Given entry 41 holds thumbnail 9 when scanned
+      And entry 41 is deleted right after the scan returns it
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then the response status is 200 and image 9 is gone
+
+    Scenario: Entries are written from the re-read data
+      Given entry 41 holds {"title": "A", "thumbnail": 9, "poster": 9} when scanned
+      When the merge runs
+      Then entry 41 holds thumbnail 7 and poster 7 and the same title
+      And the entry repository Update is called once for entry 41
+
+  Rule: A concurrent article edit survives a merge
+
+    Scenario: A body edited after planning is kept
+      Given article 1 contains the stored name of image 9 and the planning has read its body
+      And the article repository changes article 1 to the same text plus a new paragraph, right after the planning read returns it
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then the response status is 200
+      And article 1's body holds the new paragraph and the stored name of image 7 instead of image 9
+
+    Scenario: A body edited so that it no longer holds the copy name is not rewritten
+      Given article 1 contains the stored name of image 9 when planned
+      And the article repository changes article 1 to a text without the stored name of image 9 right after the planning read returns it
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then article 1's body is the edited text and the article repository UpdateBody is not called for article 1
+      And article 1 is not counted in "articles_updated"
+
+    Scenario: An article deleted after planning is skipped
+      Given article 1 contains the stored name of image 9 when planned
+      And article 1 is deleted right after the planning read returns it
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then the response status is 200 and image 9 is gone
+
+    Scenario: Only whole stored names are replaced
+      Given image 9 has the stored name "a.jpg" and article 1 contains "ba.jpg" and "a.jpg"
+      When the client sends POST /v1/media/merge with {"keep_id": 7, "merge_ids": [9]}
+      Then article 1 still contains "ba.jpg" and no longer contains the standalone "a.jpg"
+
+  Rule: A cancelled purge stops cleanly
+
+    Scenario: A request cancelled between groups stops the run
+      Given groups A, B and C are planned and the request context is cancelled after group A committed
+      When the purge runs
+      Then group A stays merged and groups B and C are untouched
+      And the run returns the context error and records no last_purge_* values and no media.purge success event
+      And failed_groups is not incremented for B and C
+
+    Scenario: The scheduler passes its context to the run
+      Given the scheduler context is cancelled while a scheduled purge is between groups
+      Then the run stops after the group in progress and records no last_purge_* values
+
+  Rule: A purge scans entries once
+
+    Scenario: A preview over many groups scans once
+      Given 6 planned duplicate groups, 40 entries and 2 content types with a media field
+      When the client sends GET /v1/media/purge-preview
+      Then contenttype.Repository.List is called once
+      And entry.Repository.ListPage is called once per content type with a media field, 2 times in all
+      And the response is the same as before this slice
+
+    Scenario: A run over many groups scans once
+      Given the same 6 groups, 40 entries and 2 content types with a media field
+      When the client sends POST /v1/media/purge with {}
+      Then contenttype.Repository.List is called once
+      And entry.Repository.ListPage is called 2 times in all, not once per group
+      And the response and the stored last_purge_* values are the same as before this slice
+
+    Scenario: The index is stale after a group but the result is right
+      Given entry 41 holds thumbnail 2 and poster 5, where 2 is a copy of group A and 5 is a copy of group B
+      When the client sends POST /v1/media/purge with {}
+      Then entry 41 holds the kept image of group A as thumbnail and the kept image of group B as poster
+      And entry.Repository.Update is called twice for entry 41
+
+    Scenario: The usage counts and the candidates come from the same scan
+      Given the duplicate group 7, 9 where only 9 is used, by 1 entry
+      When the purge preview and the purge run
+      Then 9 is the kept image and 7 is the merged copy
+      And there is one scan per call
+
+  Rule: A purge run commits one group at a time
+
+    Scenario Outline: A failing group rolls back alone
+      Given groups A, B and C are planned, in that order
+      And <failure> is armed for group B
+      When the client sends POST /v1/media/purge with {}
+      Then the response status is 200
+      And the body is {"groups_total": 3, "groups_purged": 2, "merged": <copies of A and C>, "articles_updated": <distinct articles of A and C>, "failed_groups": 1}
+      And all of group B's article bodies, entries, sites, authors and images are back to their original state
+      And groups A and C are merged
+      And the stored last_purge_merged and last_purge_articles_updated equal the response totals
+
+      Examples:
+        | failure                                      |
+        | the UpdateBody of the second article         |
+        | the article repository RepointImage          |
+        | the entry repository Update                  |
+        | the image repository Delete of a merged copy |
+
+    Scenario: Every group failing is still a 200
+      Given every group is armed to fail
+      When the client sends POST /v1/media/purge with {}
+      Then the response status is 200
+      And groups_purged is 0 and failed_groups equals groups_total
+      And no image, body, entry, site or author changed and the stored last_purge_at is set
+
+    Scenario: The run opens one transaction per planned group
+      Given 3 planned groups
+      When the client sends POST /v1/media/purge with {}
+      Then the transactor Run is called 3 times
+
+  Rule: Behaviour unchanged (the media-field walk refactor)
+
+    Scenario: The shared walk changes nothing
+      Given the media-field rule constants, the InvalidField wrapper and the walks over a content type's media fields live in one place
+      Then every scenario of features/media_field_type.feature, media_library.feature and media_purge.feature passes unchanged, except the two amended below
+
+  Rule: Amendments to earlier features
+
+    Scenario: media_library.feature "A failure deleting a copy after the rewrite is 500 and the bodies are rolled back" is amended
+      Given the image repository's Delete fails for image 3
+      When the client sends POST /v1/media/merge with {"keep_id": 2, "merge_ids": [3]}
+      Then the response status is 500
+      And article 1's and article 2's bodies are back to their original text and image 3 still exists
+
+    Scenario: media_purge.feature "A group that fails after rewriting bodies" is amended
+      Given the image repository's Delete fails for a merged image of group A, and group B is planned
+      When the client sends POST /v1/media/purge with {}
+      Then the response status is 200, "failed_groups" is 1 and "groups_purged" is 1
+      And group A contributes 0 to "merged" and none of its article ids to "articles_updated"
+      And group A's article bodies are back to their original text
+      And a following GET /v1/media/purge-preview plans group A again, and the next run converges
+
+  @manual
+  Rule: Persistence (verified by hand, see the qa.md)
+
+    Scenario: The GORM adapter rolls back on SQLite, MySQL/MariaDB and PostgreSQL
+      Given duplicates with articles, a site, an author and entries pointing at a copy
+      When a merge fails at the image delete on each driver
+      Then no row changed on any of the three drivers

+# QA procedure: media_merge_hardening
+
+Package: `test` (black-box). New file `test/media_merge_hardening_test.go`. Go only: no SPA, no env var, no live server, no real SQLite file, no real SMTP. Fake type names must be unique in the package.
+
+## Setup shared by every case
+1. Call `validator.InitValidator()` once per test.
+2. Reuse the fakes of the media tests and the purge tests: `mockImageRepo`, `mockArticleRepo`, the site, author and storage fakes, the variant file fake, the audit recorder fake, `mockContentTypeRepo`, `mockEntryRepo`, `mockPurgeSettingsRepo`, and the helpers `seedGroup` and `articleUsing`.
+3. New fake `mockMergeTransactor` (implements `transaction.Transactor`):
+   - It holds the fakes of step 2 and hands them to the function as the `Repositories` struct. In-memory fakes need no real binding to the transaction.
+   - Rollback emulation: before calling the function it snapshots the state of every fake it holds (a deep copy of their maps), and it restores the snapshots when the function returns an error. Counters (`updateCalls`, `getCalls`, `deleteCalls`) are NOT restored, so tests can still assert that calls happened.
+   - Switches: `failBegin`, `failCommit`. `failCommit` restores the snapshots and returns the error after the function returned nil.
+   - Fields: `runCalls`, and a `committed bool` that is true only between the commit and the next Run.
+   - Each fake gains `snapshot()` and `restore()` helpers in the test package only; no production code change.
+4. Fake extensions (no new method on a domain interface):
+   - `mockEntryRepo`: `listPageCalls`, `getCalls`, `failUpdateOn(n)` (already exists), `failGetOn(n)`, and `afterListPage func()` called right after `ListPage` builds its result, used to mutate or delete an entry after the scan.
+   - `mockContentTypeRepo`: `listCalls`.
+   - `mockArticleRepo`: failure switches for `UpdateBody` (per id and per call number) and `RepointImage`.
+   - Site and author fakes: failure switches for `RepointImage` and `RepointAvatar`.
+   - `mockImageRepo`: `Delete` with `failDeleteFor`.
+   - Storage fake: records `Delete` calls, with a failure switch per stored name; each record notes `transactor.committed` at call time.
+   - Variant file fake: the same recording and failure switch.
+5. Build `NewMergeMediaUseCase(...)` with the transactor, storage, variant files, recorder, the fakes, an injected `*log.Logger` over a `bytes.Buffer`, and `NewRunPurgeUseCase` / `NewPreviewPurgeUseCase` over the same fakes. The constructors are chosen by the coder. Mount the media handler on a fresh `chi.NewRouter()` mirroring `NewMediaRouter` in api/router.go, with the media_purge.qa.md setup, `jwtauth.New("HS256", []byte("test-secret"), nil)` and an admin 2 cookie. Compare error bodies as `message + "\n"`.
+6. Seed: images 7, 8 and 9 (same sha256 A), 2 and 3 (sha256 B). The type "event" has title and thumbnail (media, optional), plus a second type with two media fields (thumbnail, poster) for the walk and index cases. Seed articles, a site and an author that point at the copies. Inject a fixed clock so entry `updated_at` is known.
+7. Snapshot helper `libraryState()` deep-copying every fake. Assert "unchanged" with `reflect.DeepEqual` of before and after.
+
+## All-or-nothing
+8. Failing step table (the 9 rows of the first outline), one subtest per row. Arm the failure, POST `/v1/media/merge` with keep 7 and merge [9]. Assert 500 and "Internal server error\n". Assert `libraryState()` equals the state before, including bodies, cover ids, site and author references, entries with `updated_at` and `updated_by`, and both image rows. Assert the storage fake and the variant fake recorded no `Delete` call. Assert exactly one failed `media.merge` audit event. Use `failCommit` for the commit row.
+9. `failBegin`: 500, no write call on any fake, no file call.
+10. Two copies (8 and 9), `failDeleteFor(9)` after 8 was deleted: 500, image 8 exists again after rollback, all else unchanged.
+11. Success path: 200 and the unchanged body, entries 41 and 42 hold 7 with `created_by`, `updated_by`, `created_at` and `updated_at` unchanged, image 9 gone, the storage fake got `Delete`, and the audit event is a success with `merged` and `articles_updated`.
+12. Validation, lookup and 409 requests (all existing 400, 404, 409 cases): `runCalls == 0`.
+13. Rollback and `updated_at` / `updated_by`: arm `failUpdateOn(2)` on the entry fake, assert both entries are `DeepEqual` to the seed.
+
+## Files after commit
+14. Success: the storage fake `Delete` record has `committed == true` for every call; the variant fake records likewise. Failure rows of step 8: no records at all.
+15. File failure table (storage `Delete` fails for 9; variant purge fails for 9) with copies 8 and 9: 200 and the same body as the no-failure run, images gone, repoints kept, the other copy's removal still attempted, the log buffer holds one line with the stored name and the error text, the audit event is a success with the usual params.
+16. Purge group with a storage failure after commit: 200, `groups_purged` 2, `failed_groups` 0, merged count includes the copies of group A, the log buffer holds the failure.
+
+## Concurrent entry edit
+17. Edit after the scan: set `afterListPage` to rewrite entry 41 to a new title with new `updated_at` and `updated_by`. After the merge, entry 41 has the new title, thumbnail 7 and the edit's `updated_at` and `updated_by`.
+18. Edit that moves the entry to image 8 after the scan: entry 41 still holds 8 and the entry fake saw no `Update` for 41.
+19. Entry deleted after the scan: 200, image 9 gone, no error.
+20. Re-read data: an entry with thumbnail 9 and poster 9: both become 7, the title is kept, `Update` is called once for that entry.
+
+## Concurrent article edit
+17a. `mockArticleRepo` gains `afterFindByBody func()` called right after `FindByBodyContaining` builds its result. Edit after planning: article 1 gets an extra paragraph; after the merge it holds the paragraph and the kept stored name. Edit removing the copy name: no `UpdateBody` for article 1, not in `articles_updated`. Article deleted after planning: 200, image 9 gone. Suffix collision (`a.jpg` inside `ba.jpg`): `ba.jpg` untouched. Add a property-style table for the replacement helper (identity without the copy name, idempotence, kept name never removed).
+
+## Cancelled purge
+17b. Cancel the context from a fake hook after group A commits: A merged, B and C untouched, `Execute`/`Run` return the context error, `failed_groups` unchanged, no `last_purge_*` saved, no success `media.purge` audit event. Scheduler: `Execute` receives the scheduler context (no more `context.Background()`), cancelled between groups it stops the same way.
+
+## One scan per run and per preview
+21. Preview over 6 groups, 40 entries, 2 media types: `contenttype listCalls == 1`, `entry listPageCalls == 2`. Body equals the body from before the slice (same seed in an existing test).
+22. Run over the same seed: `listCalls == 1`, `listPageCalls == 2`, and the response and stored `last_purge_*` match.
+23. Stale index: an entry with thumbnail in group A and poster in group B ends with both kept ids, `Update` called twice for it.
+24. Media-used-only-by-entry group (existing step 30 of media_field_type.qa.md): the used copy is kept, the preview and the run each scan once.
+
+## Purge per group
+25. Failure table (UpdateBody of the second article, article RepointImage, entry Update, image Delete for a merged copy) armed for group B in plan order A, B, C: 200 and the counters of the feature, group B fully rolled back, A and C merged, `Save` counters equal the response.
+26. All groups failing: 200, `groups_purged` 0, `failed_groups == groups_total`, state unchanged, `last_purge_at` saved.
+27. Three groups: `transactor.runCalls == 3`.
+
+## Amended existing tests (the coder owns them)
+28. media_library test "failure deleting a copy": bodies are now restored and image 3 still exists. media_purge step 30: group A's bodies are restored (no longer switched), failed_groups 1, groups_purged 1, A contributes 0, the next run converges.
+29. Every other existing test passes unchanged. Constructors of `MergeMedia`, `RunPurge` and `PreviewPurge` gain the transactor and logger; update the call sites in tests only.
+
+## Behaviour unchanged (walk refactor)
+30. No new case. Run the full existing suites (`task test`) and require them to pass, as the pure-refactor proof.
+
+## Layering guards
+31. `internal/domain/transaction` imports only the stdlib and `internal/domain/*`. The use cases import no `persistence`, `gorm`, `models` or `net/http`. The GORM adapter asserts `var _ transaction.Transactor = &X{}` and is constructed only in api/dependecyInjection.go. Use the grep-style test of media_purge.qa.md.
+
+## Manual verification (not exercised by the Go tests)
+- Real SQLite, then MySQL/MariaDB and PostgreSQL via the driver tasks: seed duplicates with articles, a site, an author and entries on a copy; make the image delete fail (for example a read-only DB or a trigger); confirm no row changed.
+- Real merge against real uploads: the copy's file and variant files are gone after a 200, and still present after a forced failure.
+- Concurrent merge and entry edit with two shells (curl with the jwt cookie): the edit survives.
+- Time `POST /v1/media/purge` with many groups and 1,000 entries (one scan, not one per group).
+- Check that a SQLite transaction does not deadlock with the connection settings in `persistence/database` (all reads inside the transaction go through the tx-bound repositories).
+
+## Decisions accepted by the user
+Amend the two earlier scenarios; a file failure after commit is 200 plus a log line (injected `*log.Logger`); one transaction per purge group; entries scanned then re-read per candidate inside the transaction; article bodies are re-read and rewritten inside the transaction (the user chose to fix the body race: the plan only decides which articles change); a purge cancelled by its context stops between groups without recording a run; entries created after the scan that point at a copy are not repointed (accepted limitation, shown as missing); adapter verified by hand, Go tests use fakes with snapshot/restore rollback.

 28. Empty plan: 200 zeros, `Save` with `last_purge_at` = clock and zero counters, and a run with the empty plan's fingerprint is also 200.
 29. Partial failure, rolled back: arm `UpdateBody` to fail for the second article of group B (plan order A, B, C). Assert the body counters, B's bodies restored byte for byte, all B images present, A and C merged, B's articles absent from `articles_updated`, and `Save` counters equal the response.

 31. Concurrency: start run 1 in a goroutine, blocked in the image fake (wait on a "started" channel). Send run 2 (once with a fingerprint, once without). Assert both answer 409 with `apperr.PurgeBusyErrorMessage + "\n"` immediately (use a timeout) and no `Save`/`Delete` calls from them. Release run 1, assert its 200 body and that a later run is accepted. Run this test with `-race`.
 32. Sentinels at the use-case level, asserted separately: a stale fingerprint gives `errors.Is(err, purge.ErrPurgeConflict)` true and `errors.Is(err, purge.ErrPurgeBusy)` false; a busy guard gives `ErrPurgeBusy` true and `ErrPurgeConflict` false. Call RunPurge without any HTTP package to prove it is reusable (that test file section imports no `net/http`).
 33. Malformed body gives 400 `apperr.BodyErrorMessage`. `ListDuplicates` failure gives 500 and no `Save`.
