Feature: API responses never expose a user's secret fields

  As the maintainer of RenewCMS
  I want every HTTP response that includes user data to carry only public fields, never a
    password hash, a verification or password-reset code hash, or their expiry timestamps
  So that a bug, a future endpoint, or a client inspecting a response body can never recover a
    credential or a still-valid reset/verification secret

  Background:
    Given the public shape of a user in any API response is exactly six fields: id, username,
      email, is_verified, created_at and updated_at
    And password, password_reset_code, verification_code, verification_expiration and
      password_reset_expiration never appear in any response body, under any key name, regardless
      of their value or whether they are set

  Scenario: A successful verification response carries only public fields
    Given a user repository containing user id 7, username "alice", email "alice@example.com",
      is_verified false, whose stored VerificationCode is the bcrypt hash of "abc123" and whose
      VerificationExpiration is one hour from now
    And a valid jwt cookie for user id 7
    When the client sends POST /v1/auth/verify with body {"code": "abc123"}
    Then the response status is 200
    And the response body is a JSON object with exactly the keys id, username, email,
      is_verified, created_at and updated_at
    And the response body does not contain the keys password, password_reset_code,
      verification_code, verification_expiration or password_reset_expiration
    And the response body's is_verified is true

  Scenario: A rejected verification attempt never echoes any user field
    Given a user repository containing user id 7, username "alice", is_verified false, whose
      stored VerificationCode is the bcrypt hash of "abc123" and whose VerificationExpiration is
      one hour from now
    And a valid jwt cookie for user id 7
    When the client sends POST /v1/auth/verify with body {"code": "wrong-code"}
    Then the response status is 403
    And the response body is the plain-text apperr.VerificationFailedErrorMessage, not JSON, and
      contains no user field at all

  Scenario: Registering while no verified account exists never echoes any user field
    Given the user repository is empty
    When the client sends POST /v1/auth/register with username "bob", password "hunter2example12",
      email "bob@example.com"
    Then the response status is 200
    And the response body contains no key named password, password_reset_code,
      verification_code, verification_expiration or password_reset_expiration

  Scenario Outline: No other auth endpoint under /v1/auth leaks a user field
    Given a user repository containing user id 7, username "alice", email "alice@example.com",
      is_verified true, with a non-empty PasswordResetCode or VerificationCode where the endpoint
      under test would set one
    When the client sends <method> <path> with <body>
    Then the response status is <status>
    And the response body contains no key named password, password_reset_code,
      verification_code, verification_expiration or password_reset_expiration

    Examples:
      | method | path                             | body                                                                  | status |
      | POST   | /v1/auth/login                   | {"username":"alice","password":"hunter2example12"}                   | 200    |
      | POST   | /v1/auth/logout                  | {}                                                                    | 200    |
      | POST   | /v1/auth/password-reset          | {"email":"alice@example.com"}                                        | 200    |
      | POST   | /v1/auth/password-reset/confirm  | {"email":"alice@example.com","code":"wrong","password":"hunter2example12"} | 403 |
