R6 moderation: roles, silence and suspension, bans that write nothing on the personas, deletions, report actions

Roles (user, moderator, administrator) from the CLI and /clientapi/admin/roots/{id}/role, never one's own nor the last
administrator. Silence keeps an account's posts out of public timelines, hashtags, trends, search and relays while its
followers still get them; suspension refuses and revokes a local persona's tokens, answers 404 for its posts and
collections, holds back every delivery and tells other servers nothing new, its actor unchanged; a suspended remote
account's activities are dropped and nothing goes to its own inbox (a shared one still serves its server). A banned
login's personas are held back in memory alone (Restrictions), so nothing pairs them in stored data. Personas and groups
are deleted one at a time (PersonaRemoval, GroupRemoval), by their login or an administrator with the password. Reports
resolve with an action and a note; posts are taken down, a remote copy hidden. Warnings reach the persona as Mastodon's
moderation_warning. Every staff act goes to the staff's log. Migration _020 limits posts from servers already silenced;
a restore keeps the moderation made since the backup.

Verified: interop.sh moderation gts mastodon with SecureMode, 194 passed; restore.sh, 25 passed, now with a suspension,
a silence and a takedown made after the backup.

   the command line. Writing never fails the act it records.
 
+## Moderation (completion program R6)
+
+- **Roles.** A login is a user, a moderator (also a user) or an administrator (all three): `RootUser.SetRole` writes its
+  `Policies` (`SetAdmin` is a wrapper), and JwtEvents reads them from the database on every request. Moderators handle
+  reports, silence and suspend personas and accounts elsewhere, and remove posts; never logins (roles, bans, deletions,
+  two-factor), settings, emoji, relays, backups or statistics, which are the administrators'.
+- **What an act does** (`Domain/Moderation/AccountModeration.cs`, following the `AuthorGone` pattern): the account keeps
+  when it was silenced or suspended (`Avatar`/`ForeignAvatar.SilencedAt`, `SuspendedAt`, `AccountState`, the staff's
+  `ModerationNote`), and its posts carry `Post.AuthorLimited` or `Post.AuthorSuspended`, set on what it already wrote
+  and on what arrives or is written later (`RemotePosts.Build`, `AnnounceHandler`, `StatusService`, archive imports), so
+  a query needs no join. `Restrictions` (static, in memory, reloaded after every act and when five minutes old) holds
+  the suspended personas, the silenced ones, and the suspended accounts elsewhere with their own inboxes.
+  - **Silenced** (a persona, an account elsewhere, or a server: a domain block of `Silence` limits every post of its
+    accounts and subdomains, on arrival and when the block is made or lifted, `AccountModeration.DomainChanged`):
+    `VisibilityPolicy.IsListed` keeps its posts out of the public and hashtag timelines and streams, trends, followed
+    hashtags, status search (but what the reader met itself), the `/tags` page and the relays; its account out of the
+    directory, trends and search by a part of its name (its exact name still finds it). Its followers still get it, and
+    anyone may still open it; the Mastodon account says `limited`.
+  - **Suspended, a persona** (owner decision 2026-10-17, **tells other servers nothing new**): its Mastodon tokens are
+    revoked and refused (`MastodonController`, 401; `TokenController` and `/oauth/authorize` give it none), its streams
+    close, `/clientapi` acts as it nowhere (posts, follows, groups, profile edits, archive imports; its archive may still
+    be exported), it delivers nothing (`DeliveryService.HeldBack`, at enqueueing and again at sending; the one exception
+    is the Delete of itself when it is deleted), it takes no follower (`FollowHandler` leaves the request unanswered),
+    its scheduled posts wait (up to a month), `IsShown` hides its posts from everyone, the Mastodon mapper shows its
+    account to nobody (404 for the account, its statuses, lookup), and `PeasantsController` answers 404 for everything
+    of it but its actor and its inbox, signed or not; the actor, WebFinger and the server's counts stay exactly as they
+    were. Unsuspending gives everything back but the revoked tokens. **It is warned** with Mastodon's
+    `moderation_warning` notification (`Notifications.Warn`: from itself, as Mastodon's are, `Notification.WarningAction`
+    and the moderator's `Warning` text), which it reads once it can sign in again; meanwhile its login sees it
+    `Suspended` in `/clientapi/avatar/private/list`. Silencing warns it too, and a removed post warns its author
+    (`delete_statuses`).
+  - **Suspended, an account elsewhere:** its posts are hidden as above, `InboxProcessor` drops what it sends (but a
+    `Delete` or an `Undo`, which only take away what we hold), and nothing is addressed to it or delivered to its own
+    inbox (its server's shared inbox still serves the others there). It is told nothing.
+  - **A banned login** (`/clientapi/admin/ban/users`): its sessions end and `Restrictions` holds its personas back as
+    suspended ones (`Counted.HeldBackPersonas`, which is `BarredPersonas` plus the suspended personas), **without writing
+    anything on any of them**: flagging every persona of a login at once would pair them in stored data a moderator or a
+    backup reads. Where posts are read one at a time `VisibilityPolicy.Shown` asks `Restrictions` (`Barred`); lists leave
+    them to the Mastodon mapper, which shows no account of theirs and so none of their posts. Unbanning gives them back.
+  - **A post removed:** a post here is deleted as its author deletes it (`StatusService.Remove`: emptied, a Delete to its
+    audience, unless its author is suspended); a copy of a post elsewhere gets `Post.ModeratedAt`, hidden everywhere by
+    `IsShown` and never taken in again (its address stays known).
+  - **Deleting** a persona (`Services/PersonaRemoval.cs`) or a group (`Services/GroupRemoval.cs`) deletes everything
+    public it had, as `RootRemoval` always did for a login's personas (and now does through PersonaRemoval): its
+    tokens end, a persona's groups go with it, a Delete of the actor goes to its followers, the accounts it follows and
+    a group's members elsewhere, its posts are emptied, its name stays reserved and its documents answer 410.
+- **Routes**, every one kept in the staff's log (`persona.silence|unsilence|suspend|unsuspend|delete`,
+  `account.silence|unsilence|suspend|unsuspend`, `post.remove`, `report.resolve` with its action in the note,
+  `group.delete`, `root.role|ban|unban|delete|reset_totp`); an entry about a persona of the acting login, a post of it, a
+  group it owns or a report about it is kept without who acted:
+  - moderators (`ModeratorController`): `GET /clientapi/moderator/accounts?q=` (a name, `user@host` or an actor's address:
+    personas here, never their logins, and accounts elsewhere), `GET /accounts/moderated?offset=&limit=`,
+    `GET /accounts/{id}` (`ViewModeratedAccount`, `ViewModeratedAccountsPage`), `POST /accounts/moderate`
+    (`ModerateAccountForm`: `silence`, `unsilence`, `suspend`, `unsuspend`, a `Note` for the staff, a `Warning` for the
+    persona), `POST /posts/remove` (`RemovePostForm`), `POST /reports/{id}/resolve` (an optional `ResolveReportForm`:
+    `none`, `silence`, `suspend` or `remove_posts`, the act first, so one that fails leaves the report open; kept as
+    `Report.Resolution` and `ResolutionNote`, which `ViewReport` shows);
+  - administrators (`AdminController`, `Authorize(IsAdmin)`): `GET /clientapi/admin/roots?q=&before=&limit=` and
+    `/roots/{id}` (`ViewAdminRoot`: the one place a login is shown with its personas and the groups they own; `q` matches
+    a login's name or a persona's), `POST /roots/{id}/role` (`RootRoleForm`; never one's own, 409, and never the last
+    administrator: a demotion that leaves none is undone, 409), `POST /roots/{id}/totp/reset` (as `admin reset-totp`;
+    never one's own), `POST /personas/{id}/delete` and `/groups/{id}/delete` (`AdminPasswordForm`: the administrator's own
+    password, 403 when wrong), and the older `/ban/users`, `/unban/users`, `DELETE /remove/users`, now logged;
+  - the login itself: `POST /clientapi/avatar/private/delete` (`DeletePersonaForm`, its password) and the group's owner
+    `POST /clientapi/group/delete` (`DeleteGroupForm`, the login's password). Neither is a staff act, so neither is logged.
+- **Data:** migration `_020` and every restore run `ModerationFlags.Recompute` (the posts' flags and the accounts'
+  `AccountState` from their moderation and the silenced servers); `ProtectiveMerge` keeps P's silences and suspensions,
+  here and elsewhere, and the posts taken down, before it does; indexes on `SilencedAt` and `SuspendedAt` of both account
+  collections and a partial one on `Post.ModeratedAt`. No new collection, so backups hold it all as they did.

+- **A server silenced** (a domain block of `silence`) has its accounts' posts kept out of the public timelines here, as a
+  silenced account's are; a suspended one is refused at the inbox, as before.
+- **A post removed** by the staff: one of ours is deleted as its author would delete it (a `Delete` to its audience); a
+  copy of one from elsewhere is hidden here and never taken in again, and its server is not told.
+- **A persona or a group deleted** (by its login, its owner or an administrator): a `Delete` of the actor to its
+  followers, the accounts it follows and a group's members elsewhere; its documents answer 410 from then on, and its name
+  is never given again.

 ## Server descriptions and the crawler
 
 PrivaPub keeps statistics about servers, never about accounts (see `/stargazing` on the server).
