 ### Bot types
 
-`bot_types` is to bots what `user_types` is to users (`src/dict/bot-types-dict.ts`): `coordinator` (install-wide, written only by `ensureCoordinatorBot`), `admin` (scoped to one workspace), `worker` (no row). `BotTypePermissionMatrix`, `BotTypeTargetMatrix`, `BotTypeAssignmentMatrix`/`DeletionMatrix` are read by the generic interpreter `src/utils/rbac/type-assignment.ts`. Every run reads `grabBotRunPowers` once and gates tools on its `is_coordinator`, `admin_workspace_ids` and `can(permission)`, **never on `bots.kind`** (`kind` is only the legacy marker of the coordinator for visibility SQL). A run's powers are its type's AND its user's. A workspace admin gets `grabWorkspaceAdminTools` (delegate to members, set their workspace instructions, edit that workspace). Set via `api/admin/bots/set-bot-type`. Admins are marked with `AdminShield` (green, beside the name, never on the stone).
+`bot_types` extends `bots.kind` (worker | coordinator) the way `user_types` extends users (`src/dict/bot-types-dict.ts`): today only `workspace_admin`, each row naming its workspace (no row = just the kind; the coordinator is its kind, written only by `ensureCoordinatorBot`). A bot's role where it works is its kind plus the types it holds there (`botTypesIn`). `BotTypePermissionMatrix`, `BotTypeTargetMatrix` (keyed by role), `BotTypeAssignmentMatrix`/`DeletionMatrix` (types only) are read by the generic interpreter `src/utils/rbac/type-assignment.ts`. Every run reads `grabBotRunPowers` once and gates tools on its `is_coordinator`, `admin_workspace_ids` and `can(permission)`, never on its own check of `kind`. A run's powers are its role's AND its user's. Rows from v0.2.8 and earlier (`admin`, `coordinator`) are fixed at boot by `migrateBotTypes`. A workspace admin gets `grabWorkspaceAdminTools` (delegate to members, set their workspace instructions, edit that workspace). Set via `api/admin/bots/set-bot-type`. Admins are marked with `AdminShield` (green, beside the name, never on the stone).
 
 ### Bots, sessions, chat
 
 - **Tables:** `bots` (`kind`, `color` `#rrggbb`, `stone`, `role`, `system_prompt`; `hue` is a legacy fallback), `bot_user_faces`, `bot_sessions`, `bot_messages`, `bot_tasks`, `bot_task_steps` (unused yet). Enums in `src/dict/bot-dict.ts`.
-- **Sessions:** one thread per user per bot in its own chat plus one per workspace; split into `bot_sessions` (rollover at `AppData.BotSessionMaxMessages`, titled and summarised by `name-bot-session.ts`, summary carried into the next session). Helpers in `src/functions/backend/db/bot-sessions/`. Job results land in the job's own session, even after it closes.
+- **Sessions:** one thread per user per bot in its own chat plus one per workspace; split into `bot_sessions` (rollover at the app setting `bot_session_max_messages`, default `AppData.BotSessionMaxMessages`, via `grabBotSessionMaxMessages`; titled and summarised by `name-bot-session.ts` from the session's opening (`grabSessionOpening`; `grabBotMessages` reads the latest), summary carried into the next session only when they're linked by `previous_session_id`, which only a carry-over sets; older implicit links are cleared at boot by `clearImplicitSessionLinks`). New session (`startBotSession`) and a conversation with no active session always start fresh. The rollover carries over like the bot does (`rollOverBotSession` -> `continueBotSession`, falling back to the stored summary; kept for the next message while a job is open in the full session or there's nothing to carry), inside send-message, so the user's message lands under the summary. Helpers in `src/functions/backend/db/bot-sessions/`. Job results land in the job's own session, even after it closes, except a reply that called `continue_in_new_session` (`carryOverBotSession`; the menu's and sessions modal's Continue in new session does the same through `continueBotSession`, the model writing title and summary, refused while a job is open in the session): its summary is kept on the closed session and opens the new one as a bot message (`carried_from_session_id`), the job's `session_id` moves so the answer follows, the new session is titled by the bot then (it has no first exchange to be named from), and the old one can never be reopened (`reopenBotSession` refuses; a thread showing it swaps its composer for a link to the new one). Session lists (rail, sessions modal) reopen a session on click, as before; a carried-over one can't be, so it opens to read (`?session_id=`, `conversationHref`). The page tells them which session it shows (`announceShownSession` -> `useShownSession`): they reload, mark it Current (greyed out; without `?session_id=` the active one is), list it even when it's older than the rail's latest, and the active row then leads back. From half the session length the reply prompt suggests moving on (`longSessionNote`). Earlier sessions never enter the prompt (only the last one's summary): the thread can open them above a session (`useOlderMessages.loadPrevious`, a divider per session, quote and reply as usual), and replies get `search_past_sessions`/`read_past_session` (scoped to that user, bot and place, never the current session) when the conversation has any.
 - **Coordinator:** exactly one, the super admin's alone, created idempotently by `ensureCoordinatorBot`. Default prompt `src/data/coordinator-system-prompt.ts`, backfilled only when empty.
-- **Routes:** `/admin/bots` reopens the last visited bot (cookie `cobble_last_visited_bot_id`, never a workspace conversation) if still reachable, else coordinator (super admin) / latest bot / first workspace / empty. `/admin/bots/[bot_id]` conversation (header, thread and composer at 760px, no right panel); `/admin/bots/[bot_id]/models`; `/admin/workspaces/[id]` dashboard; `/admin/workspaces/[id]/bots/[bot_id]` same conversation scoped to the workspace.

 - **Conversation loading:** pages render everything server-side (`grabConversationProps`) **except the history**, which the client loads (`api/admin/bots/conversation-history`, merged with what's already shown, refetched on bfcache restore) and pages older messages on scroll. Rail lists go through `railBots`/`railWorkspaces` (no prompts/memory, previews cut). While a reply is due the page polls `session-messages` (`use-reply-catch-up`) in case a push was missed.
 - **Sending:** `api/admin/bots/send-message.ts` -> `enqueueBotReply` -> `wakeBotsQueue`. **Never import `src/bots-queue/index.ts` from a page or API route** (pulls the bunext runtime into page bundles). Optimistic bubble in `pending_messages` until the saved message replaces it.
 - **Composer:** Tiptap editor reading/writing markdown, drafts in `localStorage`, `@` bots / `#` workspaces written as `[bot:ID]`/`[workspace:ID]`. Enter sends (Mod+Enter in lists/code). `@tiptap/react` needs `use-sync-external-store`; the app ships an ESM stand-in in `packages/use-sync-external-store-esm` (file dependency + override; the Dockerfile copies `packages/` before `bun install`).
-- **Rendering:** markdown via `react-markdown` + `remark-gfm`, raw HTML never rendered, component map in `[bot_id]/(data)/message-markdown-components.tsx`. Inline refs, all linked by `link-computer-refs.ts` and rendered by chips in `(partials)/`: `[bot:ID]`, `[workspace:ID]`, `[computer:ID]`, `[file:ID]` (a saved file), `[folder:<volume>:<owner>:<path>]` (opens `/admin/files`), `[take-over:ID:mode]`, `[proposal:ID]`.

Parsers in `src/utils/*-ref.ts`.
 - **Copy chat** (header menu): the active session (the one on screen) as one markdown document (`api/admin/bots/conversation-export` -> `conversationMarkdown`, refs as names, message headings demoted). The clipboard write starts on the click with a pending `ClipboardItem` (`copyPendingText`), since Safari drops the gesture after a fetch.
 - **Replies/reactions:** `reply_to_message_id` (not an FK); reactions from the fixed `BotMessageReactions`, toggled by `react-message.ts` and the `react_to_message` tool, pushed as `server:bot-reaction`.
 - **Attachments:** uploaded on pick (`upload-attachment.ts`, private `media`, text extracted when possible), linked via `bot_message_media`. Replies read files of the last `BotReplyAttachmentMessages` messages. Tasks don't get files yet.

 ### Computers
 
 - An AIO sandbox per docker container on `AppData.DockerNetworkName`, managed over the docker socket (`src/functions/backend/docker/`). `containers` records every container except the app's own. `createComputer` + background `provisionComputer` (status `creating` until the health check passes). Resource changes recreate the container.
-- Only `/home/gem/workspace` is mounted, from `DATA_DIR/computers/<id>` (with `bots/`, `workspaces/`, marker `AppData.ComputerWorkspaceMarker`); the rest of home lives in the container. Deleting a computer keeps its directory. Outside docker (dev) containers are reached by IP (`pickReachableAddress`).
+- Only `/home/gem/workspace` is mounted, from `DATA_DIR/computers/<id>` (with `bots/`, `workspaces/`, marker `AppData.ComputerWorkspaceMarker`), plus the browser profile; the rest of home lives in the container.
+- **Browser profile:** `DATA_DIR/computer-browsers/<id>` mounted at `~/.cobble-browser`, which Chrome is pointed at (`BROWSER_EXTRA_ARGS=--user-data-dir=... --password-store=basic`), so logins, extensions and site permissions survive restarts and recreates. Never use the image's `~/.config/browser`: every boot overwrites its `Default/Preferences` with session-only cookies. Seed prefs (`computer-browser-preferences.ts`) are written only when missing; stale `Singleton*` links are removed before each provision. Bumping `AppData.ComputerWorkspaceLayout` recreates every computer once (`migrateComputerLayout`, skipped while a job runs on it). Deleting a computer keeps its directory. Outside docker (dev) containers are reached by IP (`pickReachableAddress`).
 - One main computer (`ensureMainComputer`), whose coordinator grant is locked (`isLockedComputerAccess`). With `MAIN_COMPUTER_URL` set (dev) it isn't provisioned. Only super admins create/delete/retry computers.
 - A bot's effective computers (`grab-bot-computers`): the workspace's in a workspace; otherwise direct grants plus its workspaces' (coordinator: all); `bots.computer_id` first. Only a `running` (healthy) computer is reached (`grabComputerMcpUrl` `ready`, `computerNotReadyMessage`).
 - **Folders (enforced in tools, not a Linux user):** a run works only in `bots/<bot>/users/<user>` (cwd, `HOME`), `bots/<bot>` and `workspaces/<workspace>` (`computerRunDirs`, `withComputerDirs`, `resolveComputerPath`; `sudo` refused).

 ### Hooks (`bot_hooks`)
 
-A secret URL, `POST /api/hooks/<token>` (`src/pages/api/hooks/[token].ts`, public, no session), that queues a hook's brief plus the raw body as a task, per user and bot like a routine (runs act as the owner, who must still reach the bot and not be read-only). Only the token's prefix and SHA-256 are stored (shown once; "New URL" rotates it); an optional HMAC-SHA256 signing secret is stored encrypted (`verifyHookSignature`). Order in the route: rate limit per IP, lookup (same 404 for every miss), rate limit per hook, signature, then `fireBotHook`. Calls are recorded in `bot_hook_events` (pruned daily) with idempotency on the sender's delivery header. A call while the last run is still pending and untried joins its brief (`mergeHookCallSql`) instead of queueing another. The payload is fenced data (`hookPayloadBlock`), and `HookRunNote` tells the bot never to take instructions from it. Failed runs retry like routines and keep why in `last_error`. Users make hooks in the conversation's Hooks modal and manage all of theirs on `/admin/routines`; **bots never create or repoint hooks**.

Order in the route: rate limit per IP, lookup (same 404 for every miss), rate limit per hook, signature, then `fireBotHook`. Calls are recorded in `bot_hook_events` with idempotency on the sender's delivery header; when a run ends (completed, failed, lost, stopped, cancelled) every call it took in gets its `response` and turns `done`/`failed` (`recordHookCallResponse`, called from the job helpers, not the handler). Calls are searchable by payload/response (`searchHookCallsSql`; Calls view, bot tools `search_hook_calls`/`read_hook_call`) and pruned daily after the app setting `hook_events_keep_days` (default `AppData.BotHookEventsKeepDays`). The caller only ever gets `202 Queued`. A call while the last run is still pending and untried joins its brief (`mergeHookCallSql`) instead of queueing another. The payload is fenced data (`hookPayloadBlock`), and `HookRunNote` tells the bot never to take instructions from it. Failed runs retry like routines and keep why in `last_error`. Users make hooks in the conversation's Hooks modal and manage all of theirs on `/admin/routines`. A hook runs in one session (`bot_hooks.session_id`, open or closed; null follows the active session): the form picks the place (the bot's own chat or one of its workspaces) and a session there, or a new one of its own, made closed beside the active one (`startHookSession`) so the chat on screen stays; a bot's proposed hook gets the session it was proposed in; a missing session is replaced on the next call (`resolveHookSession`). Changing place or session is refused while a run is open; the computer is kept only if reachable there. **A bot never makes or changes a hook on its own:** `list_hooks`, `search_hook_calls`, `read_hook_call`, `pause_hook` and `delete_hook` act directly (they only read or take away); a new hook, or a new name, brief or filter, or switching one back on, goes through `propose_hook` -> `hook_proposals` -> `[hook-proposal:ID]` card, described from the data and confirmed by that user (`checkHookProposal` runs again on confirm). What calls a hook, its computers and its signing are never proposed. A new hook's URL shows on the card only, never in the outcome the bot is told. Only chat replies propose; a hook call's own run gets no hook tools.
 
 **Browser notifications:** a hook with `source = browser_notifications` is called by a watcher on `watch_computer_id` instead of an outside service. The watcher (`src/data/notify-watch-script.ts`, Python + GLib, run as `gem` from `~/.cobble/`) owns `org.freedesktop.Notifications` on the sandbox's session bus, so Chrome hands it every notification, push ones included, instead of its silent built-in message center, and it posts each as JSON (`origin`, `title`, `body`) to the URLs in `~/.cobble/notify-hooks`. Chrome only looks for that service when it starts, so `syncComputerNotifyWatch` restarts Chrome once after starting the watcher (its sandbox supervisor brings it back), never while a task works on that computer. The hook's token is kept encrypted (`watch_token`) to rewrite that list after a container is recreated; `sync-notify-watchers` (every 5 minutes) and every change to such a hook resync it. `watch_filter` keeps only matching notifications (others are recorded as `ignored`). Computers reach the app at `COMPUTER_APP_URL` (an app setting; needed for a dev server outside docker), else the app container's name on the docker network. Sites still need notification permission in that computer's browser (a `Browser.grantPermissions` over CDP lasts only for that CDP session). Anything on the computer can read the list and call those hooks, which is one more reason payloads are only data.

+**Secrets never pass through the model.** A `user` env is one user's secret for one bot (`saveUserSecret`, reach-checked), set from the chat, listed on Settings > Secrets (own) and Environment (everyone's, remove only). In: `request_secret` -> `secret_requests` -> `[secret-request:ID]` card (masked input, `answer-request`), then a chat message naming only the key. Out: `capture_secret` (task computer tool: a file via `/v1/file/download` or a command's output, saved straight to a `user` env and added to the run's redaction list) and `show_secret` (an env by key) give `[secret:ID]`; the chip fetches the value only on click (`api/admin/secrets/reveal-secret`, `canRevealEnv`: a personal one only its own user, anything else only a super admin). Never put a value in a message, page prop, log or tool result. `SecretsNote` tells bots never to ask for secrets in chat.

Stdio servers are never proposed by bots (they run in the app container, which holds the docker socket).

 - **Backups:** DB snapshots (synchronous) and whole-data archives of `DATA_DIR` into `BACKUP_ARCHIVE_DIR`. Archives and restores outlast a request, so the route only starts the run (`startDataBackupRun`, which holds `with-backup-run-lock.ts`) and the page polls `data-status`. A restore takes a safety archive first, then restarts the process.
 - **Database browser:** strictly read-only; values cut in SQL; state in the address via `databaseHref`.
