 ## Features
 
-- **Registration and activation.** `POST /register`, `POST /activate`, `POST /activate-by-code`. Registration can be switched off and throttled; `activate_mode` is `auto`, `user` (a mailed code) or `admin`, with codes from `IssueActivationCode` and `VerifyActivationCode`.
+- **Registration and activation.** `POST /register`, `POST /activate`, `POST /activate-by-code`. Registration can be switched off and throttled; `activate_mode` is `auto`, `user` (a mailed code) or `admin`, with codes from `IssueActivationCode` and `VerifyActivationCode`. A `/register` body sets only the `User.RegisterFillable` columns: `name`, `surname`, `email`, `password` (stored as its hash), `preferred_locale` and `marketing_consent`. It cannot set `organisation_id` or `organisation_role` (membership is the administrator's or the application's), `is_onboarded`, `must_change_password`, or the activation, reset, address proof, handle and permission columns; other keys are ignored (they still reach `RegisterEvent.Payload`). `created_ip_address` and `last_ip_address` are server-set from the client address only.
-- **JWT sessions.** `POST /login`, `GET /fetch`, `POST /refresh`, `POST /logout`. Boot registers the `jwt` guard with the framework's `bouncer.Registry` and exposes it as the `jwt.auth` middleware for other plugins. Logged-out tokens go to the Postgres `jwt_blacklist`, which a background sweep prunes.
+- **JWT sessions.** `POST /login`, `GET /fetch`, `POST /refresh`, `POST /logout`. Boot registers the `jwt` guard with the framework's `bouncer.Registry` and exposes it as the `jwt.auth` middleware for other plugins. `POST /logout` ends the session however the token travels: the bearer header, or only the `token` or `auth_token` cookie the guard also reads. Every session token the request carries goes to the Postgres `jwt_blacklist` until its refresh window closes (the later of `exp` and `iat` plus `refresh_ttl`, plus a minute), so the guard refuses it on the next request and `POST /refresh` cannot revive it after the access token expired; a token whose access lifetime passed is revoked too while it could still be refreshed. The answer, a 401 included, expires the `auth.cookie.*` token cookie (the one `golem15.sociallogin`'s `token_cookie` sets), and any other session cookie the request carries, with that cookie's path, domain, SameSite and Secure. A background sweep prunes the blacklist. `POST /refresh` loads the token's user and refuses (401, `Could not refresh token`, `User not found`) a deactivated or banned user and a token issued before the user's `tokens_valid_after`; a suspension alone does not stop a refresh.
 - **Password reset and change.** `POST /forgot-password` answers the same body for known and unknown addresses; `POST /reset-password` consumes a code from `IssueResetCode`. `POST /change-password` requires the current password.
 - **Must-change-password lock.** The `user:require-password-change` console command flags an account. The flag rides on the authenticated principal (`bouncer.Principal.MustChangePassword`) for guards and other plugins to act on, and a successful `POST /change-password` clears it.
 - **Login throttling.** Failed logins are counted per user and IP in `user_throttle` (`CheckAndRecordLogin`, `RejectIfThrottled`) and suspend the account for a configured time.
 - **Rate limiting.** Every route runs behind the `user-api` bucket: 120 requests a minute per authenticated user, or per client IP for anonymous calls.
 - **Profile.** `POST /update`, `POST /marketing-consent`, `POST /avatar` and `POST /avatar/remove` (the avatar is stored through the framework's attachment storage).
-- **Organisations.** The `Organisation` model and the `organisation_id` and `organisation_role` user columns, as a foreign-key target for other plugins. An organisation has a name, a slug (filled from the name by `Slugify` when it is left empty), a description, an avatar and its members: the users whose `organisation_id` points at it.
+- **Deactivation and bans.** Deactivation is self-service and reversible: a password login or a `golem15.sociallogin` sign-in restores a deactivated account and sends the reactivate mail, and an administrator can restore it too. It ends every earlier session JWT and personal API token of the user (`RevokeUserAccess` stamps `tokens_valid_after` and revokes the `user_api_tokens` rows), so the user signs in again and gets a fresh token, while the old API tokens stay revoked. A ban is the lock: password login, social sign-in and `POST /refresh` refuse a banned user, and banning revokes the user's sessions and API tokens. Neither unban nor restore revives a token. Upgrade note: accounts deactivated or banned before this version keep their API tokens until they are deactivated or banned again (both actions are idempotent) or `RevokeUserAccess` runs for them.
+- **Organisations.** The `Organisation` model and the `organisation_id` and `organisation_role` user columns, as a foreign-key target for other plugins. An organisation has a name, a slug (filled from the name by `Slugify` when it is left empty), a description, an avatar and its members: the users whose `organisation_id` points at it. `organisation_role` belongs to that membership: the admin clears it whenever a user's organisation changes (see the Organisations screen), and an application that sets `organisation_id` itself sets or clears the role with it.
 - **User groups.** The `user_groups` table (seeded with the `guest` and `registered` groups, as in PHP) and the `users_groups` membership pivot, the `UserGroup` model and the `User.Groups` relation, which is never serialized. `UserGroupCodes` and `HasGroupCode` let other plugins check membership server-side, for example a site-admin check on the group code `admin`. No user API route reads or writes groups, and the user payload still answers `"groups":[]`. Membership is written in one place only: the `groups` field of the admin user form. Apart from that, rows leave `users_groups` only when a user or a group is deleted for good. The admin Users list can filter by group.
-- **Admin screens.** The plugin registers the Users screen with the framework's admin (`pact.HasAdminControllers`, controller ID `golem15.user.users`), the port of the WinterCMS `Users` controller: a list with search, the group, registration date and activated filters and row states (deactivated, banned, not activated); a read-only preview with a status hint; and a form with name, email, a password with confirmation, an optional invitation mail, the user's groups, the organisation, the avatar and the user's frontend permissions. Bulk actions activate, deactivate, restore, ban and unban users; the preview offers activate, unban and unsuspend while they apply. Deactivating is the soft delete; the delete button and the bulk delete remove a user for good, together with the throttle rows, group memberships and attachments. A user created in the admin starts not activated. There is no impersonation and no guest account.

Bulk actions activate, deactivate, restore, ban and unban users; the preview offers activate, unban and unsuspend while they apply. Deactivating is the soft delete, and deactivate and ban both end the user's earlier sessions and personal API tokens (see Deactivation and bans); the delete button and the bulk delete remove a user for good, together with the throttle rows, group memberships and attachments. A user created in the admin starts not activated. There is no impersonation and no guest account.
 - **User Groups screen.** Controller ID `golem15.user.usergroups`, the port of the WinterCMS `UserGroups` controller, behind `golem15.users.access_groups`: a list with the name, code, creation date and number of members, and a form with the name, the code (letters, digits, underscore and hyphen; unique), a description and the group's frontend permissions as checkboxes, stored in `user_groups.permissions` as a JSON object of code to `1`. A group can be deleted from its form; its memberships go with it and its members stay. The screen never changes who is in a group.
-- **Organisations screen.** Controller ID `golem15.user.organisations`, the port of the WinterCMS `Organisations` controller, behind `golem15.users.access_users`: a list and a form with the name, slug, description and avatar, and on an existing organisation the Members tab. Adding a member sets that user's `organisation_id` and removing one clears it; a user is never deleted. Only users without an organisation can be added, so a user moves by being removed from one organisation and added to the other (or through the organisation field of the user form). Deleting an organisation clears `organisation_id` and `organisation_role` of its members first.
+- **Organisations screen.** Controller ID `golem15.user.organisations`, the port of the WinterCMS `Organisations` controller, behind `golem15.users.access_users`: a list and a form with the name, slug, description and avatar, and on an existing organisation the Members tab. Adding a member sets that user's `organisation_id` and removing one clears it; both also clear the user's `organisation_role`, so a role never moves to another organisation or outlives the membership. A user is never deleted. Only users without an organisation can be added, so a user moves by being removed from one organisation and added to the other (or through the organisation field of the user form, where a save that changes the organisation, to another one or to none, clears `organisation_role` unless the same save writes it). Deleting an organisation clears `organisation_id` and `organisation_role` of its members first.
 - **Privileged groups.** The groups whose code is listed in `golem15.user.privileged_groups` (default `admin`) are privileged: an application may treat their members as site administrators. Three things therefore need the backend permission `golem15.users.manage_privileged_groups` on top of the screen's own permission, and answer 403 without it, saving nothing. First, membership: adding a privileged group to a user or removing it, on create and on update of the user form. An administrator without the permission sees those groups locked in the field and can still change the user's other groups. Second, the code: creating a group with a privileged code, changing a group's code to or from a privileged one, and deleting a privileged group. Its name, description and frontend permissions need only `golem15.users.access_groups`. Codes compare case-sensitively, and a group without a code is never privileged. Third, the member's account, which is protected against takeover: changing that user's email or password, and deleting them for good, needs the backend permission `golem15.users.manage_privileged_groups` on top of `golem15.users.access_users`. Without it the request answers 403 and nothing is saved; a bulk delete that contains such a user deletes none of the selected users. Everything else on such a user (name, organisation, avatar, frontend permissions, activate, deactivate, restore, ban, unban, unsuspend) needs only `golem15.users.access_users`. `PrivilegedGroupCodes`, `IsPrivilegedCode`, `PrivilegedGroupIDs` and `IsPrivilegedMember` expose the rule to other code.
 - **Frontend permissions.** `golem15_user_frontend_permissions` is the catalogue of permissions a site defines for its users (rows come from the application's migrations or seeds). A user's own choices are stored in `users.permissions` and a group's in `user_groups.permissions`, as a JSON object of code to `1` (allow) or `-1` (deny). `MergedPermissions` combines them as PHP `getMergedPermissions` does: among a user's groups the most positive value wins, then the user's own value replaces the groups'. `HasPermission` and `UserHasPermission` answer whether a code is held: only at exactly `1`, with Winter's `*` wildcards. Neither value appears in the user payload, whose `permissions` key stays `null`.
-- **Last seen.** `users.last_seen` is stamped by `POST /login` and `POST /refresh` through `TouchLastSeen`, at most once per five minutes per user. A failed write is logged and never fails authentication. It is shown in the admin list and is not part of any user payload.
+- **Last seen.** `users.last_seen` is stamped by `POST /login` and a successful `POST /refresh` through `TouchLastSeen`, at most once per five minutes per user. A failed write is logged and never fails authentication. It is shown in the admin list and is not part of any user payload.
+- **Address proof.** `users.email_verified_at` records when the account's owner proved control of the address (`User.EmailVerifiedAt`). Exactly two flows write it: the mailed activation code (`POST /activate`, `POST /activate-by-code` and the invitation link, through `VerifyActivationCode`) and a completed reset-code password reset (`POST /reset-password`). `POST /register` in `auto` or `admin` mode, `RegisterUser`, an administrator's create and the admin Activate action, `POST /change-password` and social sign-ins record none. The proof follows the address: an email change through `POST /update` or the admin Users form clears it, while a change of letter case only keeps it. The column is never mass-assigned and is in no user API payload, admin form or list. No migration or code path backfills it: accounts from before v0.1.5 have no proof. An application that trusts its imported addresses may set the column in its own data migration; this plugin does not. A social-login plugin links a verified provider's identity onto an existing account only when it is set.
+- **Handle.** `users.handle` is a unique nullable `VARCHAR(255)` generated on create (`classes.HandleGenerator`, charset `[a-z0-9._-]`, length 2–255). It is omitted from the user JSON payload (`json:"-"`). `user:backfill-handles` fills existing rows that still have none.
+- **User lighthouse authorizer.** Boot calls `classes.RegisterUserAuthorizer`: `lighthouse.From` then `Registry.Register("user", …)` if the namespace is free. `classes.AuthorizeUser` allows only `user:{id}` for that user (`lighthouse.ChannelID` on the two-segment name).
 - **Shared API tokens.** `user_api_tokens` stores one hashed personal/OAuth credential per user for the whole application. The `user.api_token` guard authenticates it for any plugin; `user.scope:<scope>` limits delegated access and `user.permission:<code>` checks the user's current group permissions. `POST/GET/DELETE /tokens` manage personal tokens, and `user:token:create`, `user:token:list` and `user:token:revoke` provide the CLI equivalent. A raw secret is shown only when created.
 - **Mail templates.** Activation, reset, reactivation and invitation mails in Polish and English (`golem15.user::mail.*`, layout `golem15.user::mail.layouts.user`); the locale follows the user (`ResolveMailLocale`). The invitation (`golem15.user::mail.invite`) is sent when an administrator creates a user with "Send invitation by email" set; it carries the user's login and an activation link, never the password.
-- **Extension events.** `RegisterEvent` fires after a user row is created; its `Payload` is a copy of the register input (extra keys a client sent included, `password` and `password_confirmation` never). `GetApiArrayEvent` lets other plugins merge keys into the user payload.
+- **Extension events.** `RegisterEvent` fires after a user row is created; its `Payload` is a copy of the register input (extra keys a client sent included, `password` and `password_confirmation` never), so it is untrusted client input. `CreatedEvent` (`classes.CreatedEventName` `user.Created`) fires from API register and admin create. `/register` logs a failing `RegisterEvent` or `CreatedEvent` listener at Error level and continues: a committed registration is never undone or failed by a listener. `DeletingEvent` (`classes.DeletingEventName` `user.Deleting`) fires from `FormAfterDelete` before `ForceDeleteCleanup` / unscoped delete, inside the same transaction. `GetApiArrayEvent` lets other plugins merge keys into the user payload.
 - **Registration for other plugins.** `RegisterUser`, `FireRegisterEvent`, `IssueToken` and `APIArray` are the steps `POST /register` runs, exported so another plugin (a first-run setup endpoint, for example) creates a user with the same validation, hashing, event, token and payload.
-- **OAuth providers.** `GET /oauth-providers` lists configured social login providers (none yet: it returns an empty list).
+- **OAuth providers.** `GET /oauth-providers` lists the social sign-in providers a social-login plugin has enabled, read on every request from its published `classes.OAuthProviderSource`. Without one it answers the empty list, as before.
+- **Sign-in helpers for social login.** `RegisterOptions.PasswordLess`, `FinishLogin`, `RegistrationSettings`, `RegistrationsFromIP`, `RefreshTTL` and `RemoteIP` let a social-login plugin create accounts and finish logins with the user plugin's own rules instead of copies.

The guarded delete runs in a transaction that first locks the user's `users` row, so two concurrent unlinks never remove the last sign-in method.

 Packages:
 
 - `controllers`: the route handlers above, `AdminControllers` (the admin controller list), `PermissionAccessUsers` and `PermissionAccessGroups`, plus the registration steps `POST /register` runs, for other plugins:
-  - `RegisterUser(ctx, app, db, fields, RegisterOptions)` validates `fields` against the user model's rules, hashes the password with `golem15.user.password.bcrypt_cost` and creates the user on `db` (which may be a transaction). It returns the validation errors instead of writing a response and never modifies `fields`. `RegisterOptions.Activate` creates the account activated; `RegisterOptions.IP` records the client IP.
+  - `RegisterUser(ctx, app, db, fields, RegisterOptions)` validates `fields` against the user model's rules, hashes the password with `golem15.user.password.bcrypt_cost` and creates the user on `db` (which may be a transaction). It fills only the `User.RegisterFillable` columns and ignores every other key of `fields`: an organisation membership and role are set with an explicit update after creation, as an application's onboarding does. It returns the validation errors instead of writing a response and never modifies `fields`. `RegisterOptions.Activate` creates the account activated; `RegisterOptions.IP` records the client IP and is the only source of `created_ip_address` and `last_ip_address` (both stay NULL without it, whatever `fields` says); `RegisterOptions.PasswordLess` stores `has_self_set_password=false` for an account whose random password the user never knew (a social sign-in), while the zero value keeps `true`.
-  - `FireRegisterEvent(ctx, app, user, fields)` fires `RegisterEvent` with `Payload` set to a copy of `fields` without `password` and `password_confirmation`, and returns the listeners' error (`/register` ignores it). Fire it after the user row is committed.
+  - `FireRegisterEvent(ctx, app, user, fields)` fires `RegisterEvent` with `Payload` set to a copy of `fields` without `password` and `password_confirmation`, and returns the listeners' error (`/register` logs it and continues). `Payload` carries every extra key the client sent, so treat it as untrusted. Fire it after the user row is committed.
+  - `FireCreatedEvent(ctx, app, user)` fires `CreatedEvent` (`user.Created`) and returns the listeners' error; `/register` logs it and continues.
+  - `FireDeletingEvent(ctx, app, user, tx)` fires `DeletingEvent` (`user.Deleting`) inside the delete transaction.
+  - `FireDeactivatingEvent(ctx, app, user, tx)` fires `DeactivatingEvent` (`user.Deactivating`) inside the deactivation transaction. The admin deactivate bulk action fires it after `DeactivateUsers` (so the user's sessions and API tokens are already revoked) for every selected user that was not deactivated yet; a listener error rolls the action back.
   - `IssueToken(app, user, r)` mints the session JWT as `/register` and `/login` do.
   - `APIArray(ctx, app, user)` builds the user payload, extended by `GetApiArrayEvent` listeners.
+  - `FinishLogin(ctx, app, db, user, ip)` runs the steps `POST /login` takes after authentication, for a caller that authenticated the user another way (a social sign-in): it restores a soft-deleted account and sends the reactivate mail, records `ip` as `last_ip_address` and touches `last_seen` (a failure there is only logged). It checks no password, throttle, activation or ban and fires no event; the caller does those checks.
+  - `RegistrationSettings(app)` returns `allow_registration`, `use_register_throttle`, `activate_mode` and `require_activation` with their defaults (`true`, `true`, `auto`, `true`), and `RegistrationsFromIP(ctx, db, ip)` counts the accounts created from an IP in the last 60 minutes (`/register` refuses at 3 with the throttle on).
+  - `RefreshTTL(app)` is the refresh window, `golem15.user.jwt.refresh_ttl` minutes (default 20160), and `RemoteIP(r)` the host part of `r.RemoteAddr` that `/login` uses for its throttle.
 - `classes`: `JWTSecret`, `GormUsers` (the `bouncer.UserProvider`), `LookupByEmail`, `UserPermissionGrants`, `UserGroupCodes`, `HasGroupCode`, `APITokenPrefix`, `MintAPIToken`, `HashAPIToken` and `RevokeAPIToken`, plus the activation/reset, throttle, mail locale and event helpers. `RegisterEvent` carries `User` and `Payload map[string]any`, a read-only copy of the register input without the password keys. For the admin and for other plugins it also has:
   - `MergedPermissions(ctx, db, userID)`, `HasPermission(merged, code)` and `UserHasPermission(ctx, db, userID, code)`, the frontend permission resolver, and `FrontendPermissionOptions(ctx, db)`, the catalogue by tab and code.
   - `PermissionManagePrivilegedGroups`, `PrivilegedGroupCodes(cfg)`, `IsPrivilegedCode(codes, code)`, `PrivilegedGroupIDs(ctx, db, codes)` and `IsPrivilegedMember(ctx, db, codes, userID)`, the privileged-group rule.
   - `ActivateUsers`, `DeactivateUsers`, `RestoreUsers`, `BanUsers`, `UnbanUsers`, `UnsuspendUser`, `ThrottleStates` and `ForceDeleteCleanup`, the user actions the admin runs. Each takes the handle of the caller's transaction.
+  - `RevokeUserAccess(ctx, db, userIDs)` ends every session JWT issued before the current second (it stamps `users.tokens_valid_after`, deactivated rows included) and revokes every personal API token of the users. `DeactivateUsers` and `BanUsers` call it; an application may call it for its own offboarding and after writing a ban directly to `user_throttle`.
   - `TouchLastSeen(ctx, db, userID)`.
+  - `OAuthProvider` (`Name`, `Label`) and `OAuthProviderSource` (`EnabledOAuthProviders(ctx)`, `KnownOAuthProviders()`), the seam a social-login plugin publishes with an explicit type argument, `app.Publish[classes.OAuthProviderSource](src)`, so the lookup finds it. `GET /oauth-providers` lists its enabled providers in order; the unlink routes accept its known names.
+  - `EndSession(ctx, app, w, r)` is what `POST /logout` runs: it blacklists every session JWT the request carries (bearer header, `token` and `auth_token` cookies) that verifies, an expired one too while its refresh window is open, until that window closes, writes the forget cookies described under JWT sessions, and returns the subject of the token the guard would read (`""` when there is none or it does not verify); only a failing blacklist write is an error.
+  - `RequestUser(ctx, app, r)` and `EndRequestSession(ctx, app, w, r)`, for handlers that serve signed-in and anonymous browsers on one route (an OAuth provider's authorize page). `RequestUser` reads and checks the session JWT exactly as the `jwt` guard does (bearer header, then the `token` and `auth_token` cookies, the blacklist, `tokens_valid_after`) and returns the user, or `nil` for an anonymous, invalid, expired or blacklisted request and for a soft-deleted user; only an infrastructure failure is an error. `EndRequestSession` is the best-effort `EndSession`: it revokes and forgets the same way (the forget cookie of `bouncer.LoadCookieConfig`), but a blacklist failure is logged, never returned.
+  - `AvatarURL(ctx, app, user, size)`, the display picture rule of the user payload at any size: the avatar thumbnail (size by size, mode auto) when the user has an avatar and a file bucket is published, the file path when the thumbnail fails, otherwise the gravatar URL. The URL may be protocol-relative or relative. The payload's `avatar_url` comes from it at 128.
+  - `HandleGenerator`, `AssignHandle(ctx, db, user)`, `CreatedEvent` / `CreatedEventName`, `DeletingEvent` / `DeletingEventName`, `DeactivatingEvent` / `DeactivatingEventName`, `AuthorizeUser` and `RegisterUserAuthorizer`.
 - `middleware`: `APITokenGuard`, `Scope`, `Permission` and `BearerToken`.
-- `models`: `User`, `Throttle`, `Organisation`, `UserGroup`, `UsersGroup` (the `users_groups` pivot), `APIToken`, `OAuthIdentity`, `FrontendPermission` and `PermissionSet`. `PermissionSet` reads a stored permission column tolerantly (NULL, an empty string, `[]`, numeric strings) and writes a JSON object of integers; `ParsePermissionSet` and `PermissionSet.Text` do the same for a column that is a plain string on its model. `UserGroup.UsersCount` is filled only by a query that selects `users_count` (the admin list does). `Organisation.Members` is the relation behind the members manager, `Organisation.AttachRelations` declares its avatar (`OrganisationAvatarField`), and `Slugify` is the slug rule. `User.FilterScope` answers the admin list scope `FilterByGroup`, and `User.AttachRelations` declares the avatar (`AvatarField`).

Membership of such a group, the group's code and its delete, and the email, password and permanent delete of its members need `golem15.users.manage_privileged_groups`. Read on every request. An empty list protects no group. |

Empty adds nothing; `open` or `closed` appends the framework's `turnstile:open` or `turnstile:closed` middleware to those two routes only (summercms v0.3.0 and later; secret in `turnstile.secret`, token in the `turnstile_token` field). `open` lets requests pass when Cloudflare is unreachable, `closed` refuses them. Any other value fails boot. |
 
 ## CLI commands
 
-| Command | Purpose |
+| Command | Purpose | Example |
-|---------|---------|
+|---------|---------|---------|
-| `user:require-password-change <email>` | Flag an account so its next session must set a new password. |
+| `user:require-password-change <email>` | Flag an account so its next session must set a new password. Ends with `Password change required for <email>`. | `bin/<app> user:require-password-change jane@example.com` |
-| `user:token:create <email> [--name api] [--scopes read,write] [--expires RFC3339]` | Create an application-wide API token and print its secret once. |
+| `user:backfill-handles` | Assign a unique handle to every user row that still has none, with a progress bar. Ends with `Assigned handles to N user(s)`. | `bin/<app> user:backfill-handles` |
-| `user:token:list` | List token metadata without secrets or hashes. |
+| `user:token:create <email> [--name api] [--scopes read,write] [--expires RFC3339] [--json]` | Create an application-wide API token and print its secret once (also under `-q`); `--json` prints the token and its details as one object. | `bin/<app> user:token:create jane@example.com --scopes read --json` |
-| `user:token:revoke <id>` | Revoke a shared API token immediately. |
+| `user:token:list` | List token metadata without secrets or hashes; `--json` prints a JSON array with the expiry, revocation and last-use times. | `bin/<app> user:token:list --json` |
+| `user:token:revoke <id>` | Revoke a shared API token immediately. | `bin/<app> user:token:revoke 12` |
+
+Each command uses the database the serve command published or, run from the console, opens one from `database.dsn` (and loads the encryption keys from `app.key`) for its duration. `bin/<app> help <command>` shows each command's long help and examples. The plugin logs through the component `user` (`log.components.user` in `config/log.yaml`).

+
+`TestRegisterIgnoresProtectedFields` posts organisation, IP and account-flag keys to `/register` and `RegisterUser` and checks that only the allow-listed columns and the server-side IP are stored; `TestRegisterListenerErrors` checks that failing register and created listeners do not fail the registration.

+`TestLogoutEndsTheSession` signs in through `POST /login` and logs out with the bearer header, with only the `token` or `auth_token` cookie, and with both a bearer and a different cookie token, then checks that the token is refused through every carrier on a `jwt.auth` route, at `/fetch` and at `/refresh`, that the forget cookies match the token cookie's attributes (also with a configured domain and SameSite), that the blacklist row lasts for the refresh window so `/refresh` stays refused after the sweep that follows the access token's expiry, that an expired but refreshable token is revoked, and which tokens a logout refuses with 401.
