fix(honcho): read Honcho 3.0.x response schema — memory reads were silently empty

Against a self-hosted Honcho 3.0.11 every read path came back empty while
the server was healthy and full of derived facts: the plugin parsed a
`conclusions`/`summary` shape the API no longer emits.

- honcho-client: typed models for the real schema — `PeerContext`
  (`representation` markdown + `peer_card`), `SessionContext` (`summary` as
  an object, `peer_representation`), wrapped `PeerCard` (a bare array on PUT
  is a 422, which also broke `honcho_profile` writes).
- plugin: the turn-time injection and `honcho_context` read the
  representation; `honcho_search` and the page's /search now use
  `conclusions/query` (observer/observed scoping inside `filters`) — a real
  ranked semantic search with fact ids, which `peer_context?search_query`
  never provided; /overview returns card + representation + conclusions.
- compose: pin the Honcho image by digest (3.0.11) — ghcr publishes no v3
  semver tags, and an untracked `:latest` pull is what drifted the schema.
- tests: fixture tests from payloads captured on the live server, plus an
  env-gated live smoke test (HONCHO_E2E_URL/_WS/_PEER, `cargo test
  -p honcho-client -- --ignored`) — run it before any future Honcho bump.

+
+## [Unreleased]
+
+### Added
+
+- The file viewer opens **word-processor documents** (`.docx`, `.doc`, `.odt`, `.rtf`):
+  when LibreOffice is installed on the server they are converted to PDF and shown as the
+  document, live-reloading when the file changes, exactly like a compiled `.tex`. A
+  document kept only inside the user's container is converted too — the server pulls a
+  copy out and converts that. With no LibreOffice the page says so and offers the
+  download, as before. The download button still saves the original document, not the
+  preview PDF.
+- Z.AI's new models are selectable on the **Models** page: **GLM-5.3** and **GLM-5.3-Flash**,
+  both with a 1M-token context. GLM-5.3-Flash is natively multimodal, so images and videos
+  attached to a message are sent to it directly instead of as a file path. Both always think —
+  Z.AI does not allow turning it off — and the reasoning control offers *low / high / max*
+  (default *max*) instead of an on/off switch.
+
+### Fixed
+
+- **Honcho long-term memory read nothing at all** against a self-hosted Honcho v3
+  server: the `honcho_context` and `honcho_search` tools answered "no context", the
+  automatic memory injection into chats silently never happened, and the *Long-term
+  memory* page showed an empty overview — while the server was healthy and full of
+  derived facts. The plugin parsed an outdated response shape; it now reads the
+  `representation` / `peer_card` fields Honcho 3.0.x actually returns, and search is a
+  real ranked semantic search whose fact ids can be deleted via `honcho_conclude`.
+- The `honcho_profile` tool could not **write** the peer card (the API rejects a bare
+  array — it wants a `{"peer_card": …}` wrapper) and read back a raw JSON envelope;
+  writes now succeed and reads show the facts, or a clean "no card set yet".
+- The **Providers** page said *API key missing* on every provider, including the ones
+  with a perfectly good key. It now reports the real state. Editing a provider no longer
+  shows the saved key in the form either — leave the field blank and the existing key is
+  kept, type a new one to replace it.
+
+### Changed
+
+- The self-hosted Honcho compose setup (`honcho/docker-compose.yml`) pins the server
+  image **by digest (3.0.11)** instead of tracking `:latest` — ghcr publishes no v3
+  version tags, and an untracked pull is what silently changed the API schema under the
+  plugin. Upgrading Honcho is now a deliberate, verified step.
+
+### Security
+
+- An LLM provider's API key is never sent to the browser any more: the provider list and
+  the edit form receive only whether a key is stored, not its value.
+
+## [0.3.0] - 2026-08-24
+
+### Added
+
+- The assistant can now explain the **Dashboard** and the admin's **Roles** page: ask it
+  why the status line says *Degraded*, whose usage the charts show (everyone's, together
+  — counts never content), what a role bundles — the simple interface, the default
+  assistant, the security groups, the new-extensions switch — or why a role edit takes
+  effect on open sessions immediately, and it answers from the in-app documentation
+  instead of guessing.
+- The **Long-term memory** page (Honcho plugin) now shows, once you have opted in, what
+  Honcho actually remembers about you: a service-status line (connected/unreachable with
+  the specific error, and your memory's processing queue), a full overview (your card,
+  derived facts, summary) and a search-or-ask box — *search* returns the raw stored facts
+  matching your words, *ask* has Honcho's AI answer a question in its own words. A
+  built-in mini-guide explains the difference. Errors say what went wrong (unreachable
+  host, rejected key, server error), not just "unavailable".
+- The assistant can now explain the **file viewer**, the **Tasks page**, your **Profile**
+  and the admin's **Users** page: ask it what a document's history button does, why a
+  `.tex` is shown instead of a PDF, how to stop a recurring job without losing it, what a
+  "cancelled" run means, what an encrypted account means when a password is forgotten, or
+  why it knows a member's age — and it answers from the in-app documentation instead of
+  guessing.
+
+- A **Files** section in the menu: everywhere you can reach, in one place — your home,
+  your personal and the shared memory, the folders and projects shared with you, plus
+  skills and documentation. Browse, open, download a folder as a ZIP, and upload, rename
+  or delete wherever you have write access; the read-only places say so. Your memory
+  notes are readable here for the first time (changing them still goes through the
+  assistant).
+- The assistant can be told what you are looking at: the eye next to the paperclip sends
+  what you have open along with your next message, so "what is this?" needs no explaining.
+  It names the page you are on; the folder you are browsing in Files or in a project; the
+  file open in the viewer and any passage you highlighted in it — line numbers included
+  where you are looking at the source — so "what is in here?" and "rewrite this sentence"
+  work without naming anything; and, on a detail page, which project (and which of its
+  tabs), member, connector, plugin, conversation, tool call or LLM request you opened.
+  The active section follows you in Tasks, Models, Background agents, the Marketplace
+  search and the mobile app. It is used only when your message is actually about what
+  you have open: asking something unrelated from inside a folder no longer sends the
+  assistant reading through it. Like an attachment, what the eye sends goes to the AI
+  provider together with your message — hover it (or tap it) to read exactly what would
+  go out, click it to stop sharing; the choice is remembered on this device, and every
+  sent message keeps a faint eye in its corner that shows, on hover, what it carried. Very long highlights are trimmed, with a
+  note saying how much was left out — the assistant can still read the whole file itself.
+  On by default.
+- Several conversations per source: open extra chats with `+`, and the tab bar you left
+  open is restored at your next login, on any device.
+- A background task now reports back into the chat that started it instead of only the
+  Inbox, and a chat shows the tasks still running under it.
+- Skills reworked for the multi-user model: a shared tree plus a per-member one, with a
+  generated index injected into the agent's prompt.
+- The agent is told what its sandbox can actually run, from a probe of its own container.
+- Event triage can be tuned per person: a check interval that overrides the instance one,
+  and notification preferences read from `user-memory/notifications.md`.
+- The assistant now remembers how you like emails and documents written — preferred
+  wording, openings, sign-offs, formal vs. informal, per-recipient exceptions — as a short
+  section of your private `user.md`, and applies it to later drafts.
+- File viewer: syntax highlighting for code files and for code blocks in the chat, a
+  hover copy button on those blocks, and history browsing for a file under git.
+- Project explorer: download a folder as a streaming ZIP.
+- Collapsible icon-only sidebar on desktop.
+- DeepInfra, as a declarative LLM provider.
+- The project coordinator offers to keep a history of a project.
+- An agent can ask which connectors it holds instead of guessing.
+- The assistant can now explain the chat window itself (tabs, the composer's controls,
+  the slash commands), the Inbox and its three kinds of pending request, and the security
+  groups behind "why is it asking me for permission?" — ask it in plain words instead of
+  hunting through the pages.
+
+### Changed
+
+- Runtime image `v4`: Debian 13 base, plus the shared libraries a headless Chromium needs.
+- Unencrypted users are unlocked and their runtimes started at boot, so Telegram, cron and
+  the background agents work after a restart without anyone opening the web app first.
+- PDFs render through pdf.js instead of an iframe.
+- The service is allowed 65536 open files instead of the default 1024. New installs get it
+  from the installer and existing ones from an ordinary update, unless you have set your
+  own limit, in which case yours is left alone.
+
+### Fixed
+
+- **Models → Text-to-speech** now fills the window like every other page. It was rendering
+  as a narrow strip in the middle of an otherwise empty screen, which made the model list
+  and its forms unreadably cramped.
+- A connector that fails to start no longer leaves its process behind. One that started
+  but answered the handshake wrong — a broken or mismatched connector — was left running
+  on every retry, and the accumulated processes eventually used up every file handle the
+  server had: within hours the app stopped answering altogether, while the process, the
+  port and every other connector still looked healthy. Stopping or deactivating a
+  connector now genuinely ends its process too.
+- The server keeps running after you log out of the box; the install / update / uninstall

+  that it was filtered.
+- LLM calls send the provider's model id on the wire rather than the local alias, and

+- `get_ast_outline` runs in the caller's workspace, gives a markdown heading a section

+- The re-login dialog no longer hijacks the login screen, the new-chat `+` menu is visible

+- **`CLAUDE.md`** (this file) — the rules whose blast radius is the whole repo (the commit rule, the production/schema constraint, domain neutrality, the event-bus rule, the crate boundaries), plus the map of the code. Keep it that way: the mechanism of one subsystem does not belong here.

Indexed in [`dev-docs/README.md`](dev-docs/README.md). **Standing rule: a change to a subsystem updates its dev-doc in the same change** — same reason as `docs/` and `CHANGELOG.md`, see [Documentation](#documentation).

+A pointer is not a summary. If the table sends you to a file, that file is where the decision was recorded and why the obvious alternative was rejected — inferring it from this one instead is how a trap already paid for gets stepped on twice.
+
+**Reading it is not conditional on the size of the change, and "the fix is obvious" is what triggers the rule, not what excuses you from it.** A one-line CSS edit, a renamed field, a typo in a label — those are exactly the changes made without opening anything, because the diagnosis felt complete after a grep. It wasn't: a `dev-docs` file is not a description of the code, it is the **rules and traps the code cannot state about itself** — invariants whose violation compiles cleanly and fails silently, a helper that must be called synchronously and looks identical to the one that must not, an enumeration that is load-bearing, the alternative that was already tried and reverted. Grepping the source finds *what* the code does; it cannot find *what you must not do to it*. Reconstructing that from the code later means reconstructing it from the one version that cannot explain itself.
+
+Two practical consequences:
+
+- **You will have to open the file anyway.** The [standing rule](#dev-docs) says a change to a subsystem updates its dev-doc *in the same change*. Opening it first costs nothing extra and is the only moment when what it says can still change what you build; opening it last reduces it to a place to type into.
+- **Read the whole file, not the section you think you need.** They are short by design. The part that saves you is rarely the part matching your grep — it is two paragraphs away, in the trap you did not know existed.
+
+The worked example is in [`dev-docs/frontend.md`](dev-docs/frontend.md): the Models → TTS page rendering 45px wide. The cause was not in the page but in a missing rule *about* the page, and the fix was not to add the missing name to a list but to delete the list — because a hand-maintained enumeration of element names fails silently, with no console error and no failed build. A grep found the symptom in three calls and would have shipped the one-line version of the fix.

+
+**Do not edit them as a side effect of work done here.** The coupling that matters is `plugin-mobile-connector`: a shipped client cannot be recompiled by this repo's build, so a protocol change is a compatibility decision, not a refactor. When a change here breaks one of them, say so and let it get its own commit in its own repo.

 ## What this repository is
 
 A **dedicated fork** of Skald, turning a single-user personal agent into a **multi-user assistant for a small trusted group** — positioned at families, but see the neutrality rule below.
 
-The design lives in **`blueprint/project-family.md`**. Read it before any architectural work; its sections are referenced by number (§0.1 neutrality, §5.1 database layout, §11 `UserManager`, §12 auth schema, §16 LLM privacy tiers, §17 sequencing). The `blueprint/` directory is **gitignored and not under version control** — treat it as the source of truth, and never assume a section says what you remember.
+The design lives in **`blueprint/project-family.md`** (see above) and is the source of truth for everything below.
 
 Load-bearing decisions from that document:
 
 - **Not upstreamable.** Nothing here needs to preserve Skald's schema or be portable back to it.
-- **~~Greenfield~~ — no longer true. The instance is in production.** There are live users with data we cannot recreate, so the greenfield licence (restructure, rename, wipe, recreate) has expired: **every schema change now needs a versioning mechanism**, and "drop the box and re-run setup" stopped being an acceptable answer. Until that mechanism exists, the only safe change is an additive one through `db::ensure_column` (see the DB section); anything that renames, drops, retypes or moves a column or table is **blocked** on building schema versioning first, not something to do carefully by hand. A user's `{userid}.db` is SQLCipher-encrypted and readable **only while they are logged in**, so a migration cannot be a boot-time sweep over every file — it has to run per user, at unlock, and be idempotent. Design for that when the time comes.

 - **Dual memory**: a private per-user pool plus a shared pool. A user's private space is encrypted so that nobody else — the admin included — can read it *through normal use of the system*. Never claim "mathematically impossible": the honest promise is transparency plus verifiability (§3).
 - **Threat model** (§2): the adversary is the **tempted admin**, who owns the box but does not recompile the binary or dump RAM. Do not design against a forensic attacker.
 - **Roles are data, not enums** (§0.1): a `roles` table binds permission-group, run-context and data-handling attributes. "Children" is a seeded preset row, never a hardcoded type.

 **The user-lifecycle reconciler** is the worked example of the rule. Creating a user, deleting one, deactivating one, or changing a shared-folder/project membership all need Docker work (provision, tear down, stop, recreate with new bind mounts); enabling or reinstalling a connector needs live runtimes re-snapshotted. None of the endpoints that make those changes touches `ContainerManager` or the refresh helpers: each announces `SystemEvent::User{Created,Deleted,ActiveChanged,MountsChanged}` / `McpGlobalServersChanged` / `ConnectorReinstalled` **after** its DB write, and one subscriber — `skald::wiring::spawn_user_lifecycle`, spawned post-construction because it reacts through `Skald`'s own accessors, holding only a `Weak` — does the reacting, sequentially and best-effort. Being off the response path matters for `ConnectorReinstalled` in particular: it re-copies files and restarts servers inside every live user's container, seconds of work the admin's install no longer waits on. The payoff is that a *future* endpoint granting membership cannot forget to remount, because remounting was never its job. Reactions never block the HTTP response, and a failure settles at the user's next login or at boot reconciliation.
 
-**Where the bus stops: reconciliation rides it, authorization does not.** `SystemEventBus` is a lossy 64-slot broadcast whose contract is *"best-effort, settles at the next login"* — right for a stale mount, wrong for a revocation, where "settles later" *is* the failure. So deactivating or deleting a user splits in two: `Skald::revoke_user_runtime` runs **synchronously in the handler, before it responds** (revoke every session → evict + cancel the `UserContext` → `UserManager::lock`, in that order, so nothing is left querying a pool we then close and the DEK leaves RAM per §9), while only the container half — stop or remove — rides the bus. Before this, `active = 0` blocked the *next* login but left live sessions working: `login` checks the flag, `require_auth` only maps token → id. Same split for security groups (see the picker section) and for connectors, where the test is worth internalising because the call is literally the same function: `Skald::refresh_global_mcp_access` is **announced** (`McpGlobalServersChanged`) when a global connector is enabled or deleted — the first only makes something *appear*, the second is already enforced by `stop_server` — but **called directly** from `global_set_access` and `user_connectors_set`, where `set_access`/`set_for_user` *replace* a grant set and the refresh is what actually revokes. Both sync call-sites carry a `DELIBERATELY SYNCHRONOUS` comment, because they look identical to the announced ones. **Never put an access revocation on a bus.**

 **Before you add a direct function call or a new import between two components, stop and ask:** is one component producing data another needs? If yes, add a variant to an existing bus and spawn a subscriber. Don't call `some_manager.log_thing(...)` from the producer — emit a `ThingHappened` event on `SystemEventBus` and let the manager subscribe.

 ### Current state
 
-`UserManager` (§11) is now **consumed**. Login exists (`crates/skald-core/src/auth/mod.rs`: `SessionStore` — `login`/`user_of`/`logout` plus `revoke_user`, the admin-side "drop every session of this user" used by `Skald::revoke_user_runtime`; the deny-by-default middleware is `src/frontend/api/guard.rs`, whose `require_auth` maps token → id and does **not** re-read the row, which is exactly why revocation must be pushed rather than polled; first admin created by `skald-setup`), and the per-user owner-bound runtime is `UserContext` (`crates/skald-core/src/skald/user_context.rs`) — resolved by `Skald::user_context` / the frontend's `require_context`, keyed off `UserManager::pool_of`, and carrying its **own `CancellationToken`** (a child of the instance one) so a single user's cron/hub/MCP loops can be stopped without touching anyone else's. The frontend owner call-sites (WS, sessions, inbox, approval-pending, projects, uploads, run-context, **cron**) route through the per-user pool; dev/stats read `llm_requests` — a *registry* table — from `system.db`, which is correct. The "owner-without-a-user" question resolved to **there isn't one**: every owner content belongs to a logged-in user (the admin included). The global owner-bound bundles (`Conversation`/`Tasks`: the "ownerless" `ChatSessionManager`, `ChatHub`, cron `TaskManager`) are still constructed but **inert** — their loops never spawn and nothing consumes their accessors; removing them is pending follow-on work (kept for now because `RunContextManager` shares the `Conversation` bundle and *is* used, being registry-backed). See blueprint §19.

 Direction of travel, decided but not yet executed: strip the **power-user surface** (self-rewriting, arbitrary shell, dev-agent suite, ticket system) and move to a **binary-first** layout — the app is built once and run from a compiled binary, not executed from its own source tree.
 
@@ -77,10 +128,6 @@ Two rules keep the boundary real, and both are enforced by the compiler:
 - **The core never names a plugin.** A plugin contributes tools through `Plugin::tools(self: Arc<Self>)` — the sibling of `http_router()` — so nothing in the core has to downcast to a concrete type. Naming one would drag every plugin in the tree into the core, including a C build via `plugin-transcribe-whisper-local`.
 - **The core never learns about the process shell.** There is no in-core restart hook — the former `restart` tool and its `tools::restart::set_restart_handler` seam were removed. The only coupling to the supervisor is now the `run.sh` exit-code protocol (exit `255` ⇒ re-exec the same binary by path), a seam no code currently triggers (kept for a future admin-driven restart). The live expression of this principle is `skald_core::boot`, which emits startup lines each shell renders (`src/boot_format.rs` here).
 
-**Plugin visibility & per-user config.** The admin surface is `#plugins` (`plugin-catalog.js`), a status board — one card per plugin with an enable toggle + health dot + a Configure button — plus `#plugin-detail?id=<id>` (`plugin-detail.js`), which holds the instance-config form for one plugin (the plugin counterpart of `connector-detail.js`). **Granting is user-side, exactly like a connector grant**: the checkboxes live in the **Plugins** section of `#users/{id}` (`users-page.js`), right below that person's connectors, and the plugin's own page keeps only a read-only roster of who holds it, linking there. The question an admin asks is "what may this person use", and answering it plugin-by-plugin meant opening every plugin in turn; one write path also means the two surfaces cannot disagree. Unlike an MCP grant — which gates a runtime snapshotted at login and so needs a synchronous revoke — a plugin grant is re-read from `plugin_access` on every request that depends on it (sidebar pages, `/plugins/mine`, and each inbound channel message: Telegram checks it per message), so a revoke lands with no push and nothing on the bus. Binding-managed plugins (`Plugin::manages_own_access`, e.g. mobile-connector) are absent from the user-side list and rejected by its writer — a box that controls nothing is worse than no box. There is **no generic per-user plugin page**: a plugin with per-user settings (Telegram's pairing, Honcho's opt-in) hosts them in its own sidebar page via `Plugin::web_pages()`, like mobile-connector. Enable/disable + instance config + access grants are gated by the `plugin.manage` capability (admin-only by construction). Visibility is a row in `plugin_access(plugin_id, user_id)`, which grants a user sight of an enabled plugin (`plugin_id` is bare TEXT, never a FK — a `plugins` row exists only after the first toggle); the table is deny-by-default but the rows are **written for you at install time** — see the default-access section below. Per-user values are stored in `plugin_user_configs` (**admin-readable system.db — never secrets**) and applied through the `Plugin::update_user_config` hook, whose default just stores the blob via the `PluginUserConfigApi` on `PluginContext.user_config`. Telegram is the reference impl: its pairing page (a `web_pages()` fragment with no backend of its own) reads the `{linked, chat_id}` status blob from `GET /api/plugins/mine` and submits the code through `PUT /api/plugins/{id}/my-config`; the override turns it into a `chat_id → user_id` binding (same write path as the `telegram_pairing` tool). Endpoints: admin `GET/PUT /api/plugins[/{id}]`, `GET /api/plugins/{id}/access` (read-only roster) + **`GET/PUT /api/users/{id}/plugins`** (the grant write path, the twin of `/api/users/{id}/connectors`); user `GET /api/plugins/mine` + `PUT /api/plugins/{id}/my-config`.
-
-**Plugin HTTP routes & web pages.** Every plugin's `http_router()` mounts at boot under `/api/plugin/<id>/` — **enabled or not**: two shared gates wrap each router (`require_auth`, then `guard::plugin_enabled_gate`, which re-checks the DB flag per request and answers 404 while disabled), so enable/disable serves/stops routes immediately with no restart, and plugin responses carry `Cache-Control: no-cache`. The router contract: cheap and safe to build pre-start, handlers tolerant of the not-running state (resolve runtime state per request through a shared cell, as mobile-connector does). A plugin may also contribute **frontend pages** via `Plugin::web_pages()` (`PluginPage { page_id, title, icon, entry, admin_only, priority }`): `GET /api/plugins/pages` returns the caller's visible pages (admin: all; others: non-`admin_only` pages of granted, enabled plugins) with `entry_url` resolved, and the sidebar renders them as menu entries routed `#plugin/<plugin_id>/<page_id>`. A single `<plugin-page-host>` (`web/components/plugin-page-host.js`) dynamic-imports the fragment ES module the plugin serves from its own router, registers its default-exported HTMLElement class, and mounts it with the `plugin-id` attribute — the fragment talks to its backend only through `/api/plugin/<id>/…` and runs with full session privileges (plugins are trusted: they ship in the binary). The frontend knows nothing about plugin page contents or behavior.

 `skald_core::boot` emits curated startup lines on the `boot` tracing target; each shell decides how to render them (`src/boot_format.rs` here). The core says what happened, never how it looks.

Each container runs as the **host `uid:gid`** (`--user`, §6 UID coherence) with `--init` (tini reaps zombies); `ensure()` **self-heals** a container that is stale on any of three axes — `--user` (e.g. an old root one), `--init`, or the **image tag** — by recreating it, and injects a passwd/shadow entry post-create so `sudo` (NOPASSWD, in the image) resolves the arbitrary uid. The image check is what makes a tag bump reach *existing* users: a container pins the image it was created from, so without it a rebuild would only ever equip new users. `build_user_fs()` assembles a user's `UserFs` (home `{WD}/homes/{userid}` → `/root`, plus each `shared/{name}` they belong to). Shells the `docker` CLI (no client crate) |
+| `crates/skald-core/src/tools/` | Built-in tools: `exec` (**runs inside the caller's per-user Docker container**; the context-free `Tool::execute` errors, so nothing can run a command outside the sandbox), `list_agents`, `fs/*` (route `user-memory/`/`shared-memory/` to `memory_docs`, every other **physical** path through `ctx.fs`), `notify`, `ast_outline`, `image_generate`, MCP tools, plugin tools, cron tools — [`dev-docs/filesystem-and-containers.md`](dev-docs/filesystem-and-containers.md) |
+| `crates/skald-core/src/container/` | `ContainerManager` (§6): per-user Docker containers — the execution sandbox. Docker is a **hard requirement**: `check_docker()` fails `Skald::new` (→ shell exits) if the daemon is unreachable.

A random 256-bit DEK encrypts `{userid}.db`; `users.database_password` holds it sealed with AES-256-GCM under `Argon2id(password, salt)`. **The AEAD tag is the password verifier** — one derivation both authenticates and yields the key, and no second hash sits in the admin-readable DB. Cleartext users store the Argon2id output directly, compared constant-time. Argon2 runs in `spawn_blocking` behind a 2-permit semaphore (256 MiB per derivation) |

Model for the summary call: the instance-wide Settings pick (`compaction_model`, a `PropertyType::LlmModel` config property declared by `compactor::config_set`) wins; else AUTO by `compaction.strength` (config.yml); a missing configured model degrades to the same AUTO path |

The decorator's `RequestLogTarget` carries the owner: metadata → `llm_requests` in the registry (`user_id`, the column the UI filters on), payload bodies/headers → `llm_request_payloads` in that user's own encrypted DB, keyed by `request_id`; session + frame come from the request's own `conversation`/`frame`, so kernel rounds, sub-agent frames and compaction summaries are all attributed with no extra plumbing (`ModelRequest::log` is unused here) |

-## DB tables (sqlx SQLite)
-
-`database/system.db` — the path is a constant (`core::db::SYSTEM_DB_PATH`), **not** configurable. `init_system_pool` creates the directory; SQLite only creates the file. Per-user files are `database/{userid}.db`, created by `UserManager::register_user` and encrypted with SQLCipher.
-
-The schema is split into two buckets (§5.1), and the split is the point:
-
-- **`create_registry_tables`** — instance-wide, readable without any user key: `users`, `roles`, `llm_providers`, `llm_models`, `transcribe_models`, `tts_models`, `image_generate_models`, `plugins`, `plugin_access` + `plugin_user_configs`, `approval_rules`, `tool_permission_groups`, `config`, `known_tools`, `llm_requests`, `mcp_catalog`, `mcp_global_servers` + `mcp_global_access`, `oauth_providers`, `role_capabilities`, `shared_folders` + `shared_folder_members`, `projects` + `project_members`, `supervision`, `system_agent_coverage`. The MCP tables back the Connectors model (§7/§14/§15 — see its own section); `oauth_providers` (accessor `db/oauth_providers.rs`) holds one row per identity provider (Google…) — endpoints + `client_id`/`client_secret` + `redirect_uri`, admin-owned household secrets (§4/§15b), never a per-user token. The last two pairs are junction-backed membership: `shared_folder_members` (accessor `db/shared_folders.rs`) for the on-disk shared folders (§6), `project_members` (accessor `db/project_members.rs`) for projects (see the Projects section) — both let a member be read-only (`can_write`) and both drive the container mount topology + the fs routing. Their FKs are registry→registry (same file), which is allowed — unlike an owner→registry key.
-- **`create_owner_tables`** — one owner's content, **identical schema in every file that has it**: `chat_sessions`, `chat_sessions_stack`, `chat_history`, `chat_llm_tools`, `chat_summaries`, `session_scratchpad`, `session_mcp_grants`, `stack_mcp_grants`, `scheduled_jobs`, `job_runs`, `system_agent_runs`, `system_agent_state`, `mcp_user_servers`, `mcp_events`, `sources`, `secrets`, `llm_request_payloads`, `memory_docs` (+ FTS5 `memory_docs_fts`), `reports`. `mcp_user_servers` (a user's activated per-user connectors) carries `catalog_name` as a **bare `TEXT` snapshot** of `mcp_catalog.name`, never a FK — an owner→registry key would fail every INSERT; for an OAuth connector it also snapshots `oauth_provider` + `deliver_json`, and its `api_key` column holds the refresh token (in the SQLCipher-encrypted file, so no column crypto). Because `memory_docs` is an owner table, one definition backs **private** memory in each `{userid}.db` and **shared** memory in `system.db` (the household owner) — see the memory namespace note below. (`projects`/`project_tickets` were owner tables in the single-user past: projects are shareable now, so `projects` + `project_members` are registry tables and `project_tickets` is gone.)
-
-**The schema is no longer greenfield** (see the production note at the top): a full recreate is not an option anymore. `db::ensure_column` — `ALTER TABLE … ADD COLUMN` swallowing the "duplicate column" error, a no-op on a fresh DB where the `CREATE TABLE` already carries it — is therefore not a convenience for dev boxes anymore but the **only** change shape that is currently safe, and additive-with-a-default is the shape to design towards. Used for the OAuth columns on `mcp_catalog` / `mcp_user_servers`. Anything destructive waits for real versioning.
-
-**No foreign key in the owner bucket may point at a registry table.** SQLite cannot enforce a key across files, not even through `ATTACH`, and sqlx turns on `PRAGMA foreign_keys`: the `CREATE TABLE` succeeds and every `INSERT` fails. `db::tests::owner_tables_stand_alone_with_foreign_keys_on` enforces this by running the owner schema against a database holding nothing else, then inserting a row into each table. One key crossed and was fixed: `chat_history.model_db_id` (dropped — write-only, and `llm_requests.model_name` already records the model).
-
-**Memory namespace (blueprint §5).** `memory_docs` (accessor `db/memory_docs.rs` — `get`/`upsert`/`list`/`search`(FTS)/`delete`) backs a virtual note store surfaced through the fs-tools, **not** the disk. Two sibling roots (not the blueprint's nested `memory/{userid}` + `memory/shared`): `user-memory/…` routes to the caller's own pool (`ToolContext::pool`), `shared-memory/…` to the system pool (a singleton captured in `fs::register_all`). `tools/fs/classify_memory()` decides on the raw first path component (a `..` in the tail clamps inside the store, never escapes to disk); `read_file`/`write_file`/`list_files`/`edit_file`/`insert_at_line`/`replace_lines`/`search_file` override `run_with` to route memory paths (each extracting a pure transform shared with its on-disk `execute`) and leave every other path on disk. The HTTP surface routes them the same way: `GET /api/file` classifies **before** `resolve_view_path` and serves the note from `memory_docs` (caller's pool / system pool), so the file viewer opens `user-memory/…` and `shared-memory/…` like any file, and `show_file_to_user` accepts memory paths too (existence-checked on the right pool). Approval (seeded in `seed_fs_path_rules`): `user-memory/*` is `@fs_any allow` (private, frictionless); `shared-memory/*` is `@fs_read allow` + `@fs_write require` — reads free, **writes need approval** so the agent can't silently push one person's data into shared memory. `grep_files` stays disk-only (regex-across-tree ≠ FTS); ranked full-text recall over notes is a separate tool, `memory_search` (`tools/fs/memory_search.rs`), over the `memory_docs` FTS index — allowed by a path-less rule (it takes `query`, not `path`).
-
-**Supervision + coverage (registry).** `supervision(subject_user_id, supervisor_user_id)` (accessor `db/supervision.rs`) is the §0.1 **supervision edge** — a generic directed edge between two users, deliberately attribute-free, whose domain reading ("a parent watches a child") lives only in seed data and UI copy. It answers two questions with one table: *whom does a background agent look at* (`subjects()`) and *who may read what it produced* (`supervisors_of()`, which is what `reports.audience = 'supervisors'` resolves against). Both FKs are registry→registry, so the cascade is real in both directions. `system_agent_coverage(agent_id, subject_user_id, covered_through)` (accessor `db/system_agent_coverage.rs`) is the per-subject watermark that makes "everything since last time" a window: it sits between `system_agent_runs` (a history for the human, skips idle passes) and `system_agent_state` (attempt marker, advances on **every** tick and **before** the work — which is precisely why it can never delimit the window the work is about), and differs from both by advancing **only on a completed pass**, so a crash re-covers rather than skips. Deriving it from the last report's `period_end` was the obvious alternative and is wrong for one ordinary reason: a supervisor deleting an old report would rewind the scheduler and regenerate the report they just discarded — a document is the user's to delete, scheduler state is not. Registry rather than owner because the pass runs in *some* supervisor's runtime and which one depends on who is logged in that night; the acting user's file would give one subject two unsynchronised clocks.
-
-**Reports (`db/reports.rs`, blueprint §13).** The documents system agents write about a stretch of time — a daily review of a supervised account, a weekly "what you struggled to get done" digest. **The second two-homes table**, for the same reason as `memory_docs` and with the same mechanics: one owner schema, and the file a row lands in *is* its audience. A `{userid}.db` row is that user's own report, behind SQLCipher; a `system.db` row is an instance report, written *about* someone *for* the people who supervise them and therefore cleartext to whoever owns the box — deliberately, since they are the intended reader (§2). Which file a producer writes into falls out of its own `AgentScope` with no new concept (`PerUser` → `ctx.pool`, `Instance` → the registry pool it already holds), and **the subject of an instance report cannot see it** because their tools only ever reach their own pool — the invisibility is structural, so nothing anywhere filters by reader. `subject_user_id`/`producer_user_id`/`run_id` are bare snapshot columns, never FKs (owner→registry would fail every INSERT; for an instance row the `system_agent_runs` trace sits in the *acting* user's file). `kind` is producer-declared text, not an enum (§0.1). Rows are immutable but for `mark_read`, whose `read_at IS NULL` guard makes acknowledgement **shared and first-reader-wins** — two admins, one alert, dealt with once. Consequence worth internalising: since the admin cannot open the subject's encrypted sessions, **there is no click-through to the evidence** — whatever justifies a report must be narrated in its body, under the same rule the shared memory lint already follows (say which conversation and what kind of problem, without reproducing the sensitive line). **Currently there is no producer, no API and no UI** — the table, its accessor and its tests are the whole of it.
-
-**Memory injection into the prompt**: `AgentSystemContext::load_inject_memory` (`loop_adapters/system.rs`) routes each `meta.inject_memory` entry — `user-memory/…` → owner pool, `shared-memory/…` → the shared (`system.db`) pool, both via `memory_docs::get`; anything else (`data/…`, `$WD/…`) is a disk read. The shared pool is threaded `ChatSessionManager` → `UserLoopRuntime` → `AgentSystemContext`. `assistant` and `project-coordinator` inject `user-memory/index.md` + `shared-memory/index.md`.
-
-**Prompt substitutions**: an `AGENT.md` may carry `<!-- KEY -->` placeholders; `agents::resolve_includes` turns each into a `__KEY__` sentinel, replaced at request time. Two are resolved by the system-context source itself (`loop_adapters/system.rs`) from the session owner (`user_id`) + registry (`shared_pool`), so every source (WS, mobile, cron, sub-agents) gets them with no caller plumbing: `__SHARED_FOLDERS__` (the user's shared-folders table) and `__USER_PROFILE__` (the owner's directory profile: `Name`, `Date of birth` with age computed at build time, `Sex`, `Preferred language`, admin `Notes` — unset values render as explicit `unknown` / `not specified`, the `Notes` line is omitted when empty). Any other key comes from the per-call `SendMessageOptions::system_substitutions` map.
-
-`system.db` still gets **both** bucket functions — but no longer because the migration is unstarted. It gets the owner schema because it *is* the owner of **shared** memory (`memory_docs`) plus, for now, the globally-scoped `secrets` (`SecretsStore` is built on the system pool and shared by reference into every `UserContext`; the global runtime's *config* now lives in the registry table `mcp_global_servers`, and per-user connector config in each user's owner `mcp_user_servers`). The global runtime no longer writes `mcp_events` there: notification persistence is an explicit `McpManager::new` argument (`EventLog::{Persist,Discard}`), `Discard` for the ownerless global runtime and `Persist` for each per-user one, because an event belongs to whoever it happened to and its only reader (event triage) is per-user. Every *other* owner table is created there but never written to anymore — the global owner-bound managers that would write them (chat/jobs/etc.) are inert (see "Current state"). Fully dropping `create_owner_tables` from `system.db` is blocked on the §4 scope decision for secrets, not on call-site migration.
-
-`users` (`crates/skald-core/src/db/users.rs`) holds the directory plus auth material. It lives in the system DB, which the box owner can read, so it must never store anything that derives a user's key. `Credentials` is an enum mirroring the table's `CHECK`: an encrypted user carries a **wrapped DEK** (whose AEAD tag *is* the password verifier — hence no `password_hash`); a cleartext user carries an ordinary verifier, or none. `User` is deliberately not `Serialize` and its `Debug` redacts key material — use `User::summary()` for anything leaving the process. `role_id` references `roles(id)` (the `roles` table is now seeded before `users` in `create_registry_tables`). A nullable `locale` column (additive via `ensure_column`) holds the per-user UI language override; role-driven conventions live in the free-form `roles.attrs` JSON — never new columns per attribute — parsed at a **single point** by the typed `db::roles::RoleAttrs` (`ui_mode`, `permission_groups`, `chat_agent`, `auto_grant` — the last one being why that struct's `Default` is hand-written, see the default-access section): `ui_mode` (see the frontend section) plus the role's **security-group set** (`roles.permission_group` = the default group, `attrs.permission_groups` = additional allowed groups; `Role::effective_groups()` = the union, `roles::role_allows_group()` gates it with `admin` short-circuiting to all). See the security-group picker in the frontend section. The role's **default entry (chat) agent** is `attrs.chat_agent` — the neutral `chat`-type agent members of the role land on (§0.1: data, not an enum). Resolved by `roles::default_chat_agent_for_user(registry_pool, user_id)` — the single seam behind both the per-user `ChatHub`'s `default_agent` (snapshotted at login in `UserContextFactory::build`, like fs/MCP access, so **every** session-creation path — explicit `provision_session`, lazy WS `get_or_create_session`, notify — honors it) and `provisioning_for_source`'s non-project branch. Falls back to `agents::DEFAULT_CHAT_AGENT` (`"assistant"`, the renamed former `main`) when unset. Seeded: `admin`/`member` → `assistant`, `children` → `kid` (Companion). A per-user override is future work, layering on top in the same resolver. The stack **root frame** is created with the session's own `agent_id` (not a literal) — `config.agent_id` (from the frame) drives which prompt runs, so a wrong id there silently runs the wrong agent. The admin-managed **directory profile** lives in three more additive columns — `birthdate` (ISO `YYYY-MM-DD`), `sex` (free text), `notes` (admin-authored) — edited only from the Users admin page (`set_directory_fields`; validation — real non-future date, length caps — lives in the `users_mgmt` API, not the db layer) and rendered into agent prompts by the `__USER_PROFILE__` substitution (see above). They are directory metadata written *by* the admin *about* the user, so the registry is their honest home under the §2 threat model.
-
-## Filesystem & containers (blueprint §6)
-
-Each user has one **permanent Docker container** (`skald-{userid}`, our own `skald-runtime` image with python+node and a preinstalled shell toolbelt), created on user creation and started at boot (`ContainerManager`, `crates/skald-core/src/container/`). Docker is **required**: a missing daemon fails `Skald::new` and the process exits. **What goes in the image vs. what the agent installs on demand** is a real trade, and the Dockerfile states its rule: `sudo apt-get install` works in the sandbox but re-runs on **every container recreate**, inside a task, where it costs latency and can fail — while the image is **one, shared by every container**, so preinstalling costs its size once for the whole box. Anything an agent reaches for repeatedly is therefore baked in; `build-essential`/`python3-dev` and `pandoc` are deliberately left out as big *and* self-recoverable. The container runs as the **host `uid:gid`** (not root) so files created in-container and by the host-side fs-tools share ownership on the bind mounts (matters on native Linux; masked on macOS Docker Desktop). Because that user isn't root, the image ships passwordless `sudo` (a passwd/shadow entry is injected at create) so an agent can still `sudo apt-get install …`; `--init` runs tini as pid 1 to reap zombies.
-
-The agent sees **one namespace**, routed on the first path component. The choke point is `UserFs` (`core-api/src/user_fs.rs`, a pure value type carried in `ToolContext.fs`), plus `resolve_host_path()` in `tools/fs/mod.rs`:
-
-| Agent path | Backing | Routed by |
-| ---- | ---- | ---- |
-| `user-memory/…` | SQLite `ctx.pool` (`{userid}.db`) | `classify_memory` → `memory_docs` |
-| `shared-memory/…` | SQLite `system.db` | `classify_memory` → `memory_docs` |
-| `shared/{X}/…` | host `{WD}/shared/{X}` (if a member) | `UserFs::host_base_and_tail` |
-| `projects/{O}/{S}/…` | host `{WD}/projects/{owner_userid}/{S}` (if a member) | `UserFs::host_base_and_tail` |
-| `~/…`, relative | host `{WD}/homes/{userid}` | `UserFs::host_base_and_tail` |
-| any other absolute path (`/tmp/…`, `/etc/…`) | the **container's own** filesystem | `resolve_target` → `container::exec_fs` |
-
-Two views, **one storage**: for the mounted subtree the fs-tools run **host-side** in the Skald process on `{WD}/homes/{userid}` + `{WD}/shared/{X}`; `execute_cmd` runs **inside the container** (`docker exec -w <container-path> skald-{userid} sh -c …`, via `ExecuteCmd::run_with`) on the same paths bind-mounted (`homes/{userid}`→`/root`, `shared/{X}`→`/root/shared/{X}`, read-only when `can_write=0`). A file written in the container appears to the host fs-tools and vice versa.
-
-**The security boundary is the container, not the mounted subtree — the mount is the *fast* path, not the only one.** An agent already reaches every corner of its container through `execute_cmd`, which runs there with passwordless `sudo`; fs-tools that stopped at the mounts were not protecting anything, they were offering a poorer view of the same sandbox, and the model answered that by shelling out (the observed failure: `read_file /tmp/cv.txt` → *"path escapes your workspace"* → the agent re-read it with `cat`). So `resolve_target` routes a physical path to one of two backings. An **absolute** path is container vocabulary — it is what `execute_cmd` prints — so it is reverse-mapped through `UserFs::container_to_agent` first: landing on a mount takes the host path (**`/root/x` *is* `~/x`**, which the tools used to reject outright, since `PathBuf::join` with an absolute tail silently discards the base and the result then failed the prefix check); landing nowhere means it exists only in the container, and `container::exec_fs` acts there over `docker exec` (paths passed **positionally** as `$1`, so a path containing `$(…)` is data, not syntax). Membership is not bypassed: `/root/shared/{X}` for a non-member still resolves to the same error as `shared/{X}`.
-
-**One implementation per tool, not two.** Every single-file fs-tool already funnels through the same shape — resolve, then run a sync `execute` over one absolute host path — so the container branch is a **shuttle** (`fs::Shuttle`, behind `fs::run_physical`): pull the file out of the container, run the *unchanged* tool on the copy, push it back if the content changed (compared by bytes, not mtime, whose one-second resolution would miss a fast edit). Nothing about a tool's messages, diffs or pure transforms is duplicated. A missing remote file is deliberately **not** pre-created — `write_file` reports "Created" vs "Overwrote" from whether the path existed, and a placeholder would make every creation lie. Three tools opt out of the shuttle because a single file is the wrong unit: `list_files` lists in place via `exec_fs::list` (`find -printf`; `line_count` is omitted, since counting lines would turn a listing into a `docker exec` per file), `read_file` reads container paths as text (a shuttled copy is gone by the time the projection would inline a `MediaRef`, so media stays a mount-only feature), and `grep_files` **refuses** container paths with a pointer to `execute_cmd` + `rg` — its regex flavour, glob, windowing and offset would all have to be re-derived from ripgrep's flags, and a grep that answers *almost* the same is worse than one that says where to go. The viewer follows the same routing through `resolve_view_target` (`GET /api/file` and `show_file_to_user` open container paths; served without an ETag, so the editor stays read-only there).
-
-**The memory roots are signposted inside the container, not merely absent.** `user-memory/`/`shared-memory/` are virtual, so nothing of them existed on disk — and the nothing was worse than it sounds: `cat user-memory/x.md` returned a bare ENOENT (which reads as *the note is missing*, not *wrong door*), while `mkdir -p user-memory && echo … > user-memory/x.md` **succeeded**, writing a real file into the home that no reader ever visits and that the next `ls` then confirms as if it had worked. Each root is therefore a **read-only bind mount** (`{WD}/.memory-signpost/{root}` → `{container_home}/{root}:ro`, gitignored, rewritten from consts on every `ensure`) holding a README that names the tools. Read-only *as a mount*, not as a mode: the container user has passwordless `sudo`, so a `chmod` would be a suggestion, whereas `:ro` holds — remounting needs `CAP_SYS_ADMIN` (verified: write, `sudo` write, `sudo chmod`, `sudo mount -o remount,rw` and `sudo rm` all fail). A README rather than an empty dir because `Permission denied` is an error, not an instruction — models answer it by reaching for `sudo`; the README puts the correction in the directory the failing command just named. These mounts are deliberately **not** in `UserFs`: they back no agent path and the host-side fs-tools must never resolve into them. They are the **fourth self-heal axis** in `reusable()` (`signposts_mounted`) rather than an `IMAGE_TAG` bump, since the image is unchanged and a bump would make every box rebuild it to fix a mount. The matching half is in `classify_memory`, which now strips the home spellings (`./`, `~/`, `/root/`) before matching the root — without it `~/user-memory/x.md` missed the match, fell through to the disk router, and became exactly the invisible physical file the signpost exists to prevent.
-
-**Containment** (`resolve_host_path`) is unchanged and still guards **the host branch**: every path that lands on a mount is canonicalized (following symlinks) and prefix-checked against its mount base, **fail-closed**. That check is what it always was — the defence against a symlink planted from inside the container pointing at the **host's** `/etc`, which the host-side tool would otherwise follow off the box. Opening the container branch does not weaken it: that branch never touches the host filesystem, so there is no host to escape from, and the check keeps applying to everything mounted. `grep_files` stays disk-only (regex ≠ FTS; memory → `memory_search`) but resolves its root the same way. `execute_cmd`'s `workdir` is an agent path mapped to its container path via `UserFs::to_container`.
-
-The threading: `UserContext.fs` (built by `container::build_user_fs` at login, snapshotting shared memberships) → `ChatSessionManager` → `ChatSessionHandler.fs` → `ToolContext.fs`. **Admin CRUD is wired** (`src/frontend/api/shared_folders.rs` — `GET/POST /api/shared-folders`, `PATCH/DELETE /api/shared-folders/{id}`, `POST`/`DELETE .../members[/{user_id}]`; UI `shared-folders.js`): a create/describe/delete + per-member `can_write` surface, and each mutation emits `SystemEvent::UserMountsChanged`, on which the lifecycle reconciler runs `Skald::refresh_user_mounts` — rebuilding the affected user's fs + container mounts **in place**, so a membership change lands without a re-login (blueprint §6's "admin CRUD" + "membership refresh without re-login" TODOs, now closed; it still settles at next login/boot if the live remount fails). `execute_cmd` /stop is robust: the command runs under `setsid -w` in its own process-group (leader pid recorded in a container pidfile), and a `KillReaper` drop-guard reaps that group on /stop **or** timeout via a detached `docker exec` that walks `/proc` and kills members by **positive pid** (the container's dash mishandles `kill -<pgid>`); the pidfile is passed positionally (`$1`), and the container's `--init` (tini) reaps the killed processes so no zombies accumulate. **Per-user MCP connectors now run inside this container** (§7) — the container infra enabled it; see the MCP connectors section.
-
-## Projects
-
-A **project** is a shareable, self-service workspace: a folder at `{WD}/projects/{owner_userid}/{slug}` plus membership in the registry. `projects` (accessor `db/projects.rs` — slug is immutable, `UNIQUE(owner_user_id, slug)`) + `project_members` (junction with `can_write`; the owner is always a write-member, so a private project = one member). Sharing is **not** admin-gated: the owner and any write-member can add/remove/re-grant members and edit metadata; only the owner can delete. Each membership mutation emits `SystemEvent::UserMountsChanged` for the affected user; the lifecycle reconciler remounts their container in place (`Skald::refresh_user_mounts`), so the folder is browsable at once (the explorer reads host-side) and reachable from `execute_cmd` a moment later. The mount appears in the agent namespace as `projects/{owner_username}/{slug}` (host keys on the stable userid, agent path on the username) — read-only members get a read-only bind mount in the container.
-
-**API** (`src/frontend/api/projects.rs`): `GET/POST /api/projects`, `GET/PUT/DELETE /api/projects/{id}`, `POST /api/projects/{id}/members`, `DELETE .../members/{user_id}`, `POST /api/projects/{id}/session`. `ProjectDetail` carries `root_path` — the agent path of the folder, computed server-side (owner username ≠ `owner_name`, which may be a display name) — the explorer's root. A `project-{id}` chat source provisions the `project-coordinator` agent with a project `RunContext` (`provisioning_for_source` → `skald_core::projects::build_project_run_context`: `project_root` + a system block with name/description/folder/members); every member keeps their **own private** `project-{id}` session — only the folder is shared.
-
-**UI** (`web/components/projects/`): `index.js` (`<projects-page>` host — hash-routed: `#projects`, `#projects/{id}`, `#projects/{id}/sharing`, back/forward-aware), `project-list.js` (card grid + create/edit/delete modal), `project-board.js` (`<project-board-section>` — the detail page: header with **Open chat**, then a **Files / Sharing** tab bar using the `.project-tab-bar` styles in `css/projects/board.css`), `project-files.js` (`<project-files-panel>` — the explorer). The mobile app has its own read-only `shared/projects-page.js` (list → open project chat).
-
-**The explorer** (`project-files.js`): one directory at a time via `GET /api/files/dir?path=…` (new endpoint in `src/frontend/api/files.rs`: immediate children with `name/path/is_dir/size/created_at/modified_at`, dirs-first; same `resolve_view_path` scoping as `/api/file`). Breadcrumb rooted at the project (`/` = `root_path`); file click → `window.openFile` (existing viewer); folder click → navigate. **Live**: it subscribes the open directory on the existing `/api/file/watch` socket (`web/lib/file-watcher.js` singleton — `notify` NonRecursive on a dir reports its direct children) and reloads debounced 300 ms, so files created by other members or by the agent in-container appear without a refresh. Write actions (new folder, upload incl. drag&drop, rename, delete) are shown only to `can_write` members and ride the existing `/api/file` endpoints — `POST` gained `dir:true` (mkdir), `DELETE` handles directories (`remove_dir_all`), and binary upload is the new `POST /api/file/upload?path=…` (raw body, 256 MiB `DefaultBodyLimit`). **Server-side write gate**: all `/api/file` write handlers now call `UserFs::can_write_to(agent_path)` (core-api) — home → true, `shared/`/`projects/` → the membership's `can_write`, `docs/` → false — closing the host-side bypass of the read-only bind mount (the container mount only gates in-container writes).
-
-## MCP connectors (blueprint §7/§14/§15)
-
-MCP servers are surfaced to users as **"Connectors"** (UI naming; `mcp`/schema stays neutral, §0.1). The old single owner table `mcp_servers`, the agent-facing `register_mcp`/`delete_mcp` tools, and the `mcp` kinds of `list_items`/`toggle_item` are **gone**. Connectors are now admin-curated and user-activated through the Connectors UI/API — never written by the agent, which closes the §14 RCE vector (prompt-injection → agent writes+registers a local script → arbitrary code on the box).
-
-**Two runtimes, one view (§7).** A session's MCP tools are the **union** of:
-
-- **Global runtime** — shared, stateless connectors (web-search, Tavily…) that run on the **host**, connected at boot from `mcp_global_servers` by `McpManager::initialize`. Filtered per user by `mcp_global_access`.
-- **Per-user runtime** — the connectors a user has activated, run **inside their container**, started at first login from that user's owner `mcp_user_servers` and living until restart (§9; the `docker exec -i` children die via `kill_on_drop` when the `UserContext` drops).
-
-`McpProvider` (`mcp/provider.rs`) is the trait the session code talks to, so `all_tool_defs` / `render_mcp_list` / `ActivateTools` never learn which runtime owns a server. `McpManager` implements it directly (used for the inert ownerless bundle, §19); `UserMcpView` implements it as `global ∪ user`, where `accessible_global` is a snapshot of `mcp_global_access` captured when the `UserContext` is built (like fs membership). Both runtimes share `McpManager::connect_all(specs, boot)`; `McpServerSpec` + `global_row_spec`/`user_row_spec` turn a DB row into a connectable spec (a per-user `local_script` spec targets the user's container).
-
-**Authorization is a capability on the role, not `if role==admin`** (§0.1/§14 — `db/role_capabilities.rs`): `mcp.register_remote` + `mcp.register_local_from_catalog` are self-service (seeded on every new role by `roles::create` via `seed_defaults`); `mcp.register_local_script` + `mcp.manage_catalog` are admin-only. `admin` holds every capability by construction (short-circuit in `has()`). API handlers gate through `require_cap`.
-
-**Tables** (see DB section) — registry: `mcp_catalog` (admin-vetted templates; holds only the *schema* of what an activation must supply, never live creds — plus, for OAuth, `oauth_provider` + `oauth_scopes_json` + `deliver_json`), `mcp_global_servers` + `mcp_global_access`, `oauth_providers` (per-provider client creds), `role_capabilities`. Owner: `mcp_user_servers` (per-user activations; `api_key` encrypted at rest — the refresh token for an OAuth one — `catalog_name`/`oauth_provider`/`deliver_json` bare `TEXT` snapshots).
-
-**Endpoints** (`src/frontend/api/mcp.rs`, mounted in `api/mod.rs`) — admin: `/mcp/catalog` (GET/POST/DELETE), `/mcp/global` (list/enable/delete + `/{id}/access` GET/PUT), `/mcp/providers` (GET/POST + DELETE `/{name}` — OAuth provider creds, secret never returned to the browser). User: `/mcp/available`, `/mcp/activate`, `/mcp/activated` (+ DELETE `/{id}` to deactivate), `/mcp/oauth/start` + `/mcp/oauth/complete` (the §15 OAuth login), `/mcp/login/status` + `/mcp/login/reset` (the §15 QR/device login — see below). `connectors.js` (`<connectors-page>`) is the **single** Connectors surface — a row list, one row per connector (there is no separate catalog page): the user view (activate/deactivate + granted globals) always, plus the admin affordances when `role_id === 'admin'` — the **Add connector** dropdown (from the Marketplace, or manually via the `#connectors/new` sub-page), per-row removal from the catalog, and the **Sign-in providers** modal. The Marketplace stays its own page (`marketplace.js`), reached from that dropdown and linking back to `#connectors`. `connector-detail.js` (`<connector-detail-page>`) is a connector's own page and hosts both the OAuth login panel and the QR login panel.
-
-**Dependency reconciler (`mcp::install::ensure_installed`).** Copying a local-script connector's files into a container never installed its deps. `ensure_installed` closes that: a **content-hash reconciler** keyed on the connector's *source* files (not a version string) that, when the hash changed, re-copies the files and installs deps inside the container — `npm ci --omit=dev` (node, from `package.json`) and/or `pip install --target .pydeps` (python, from `requirements.txt`, put on the server's `PYTHONPATH` by `user_row_spec`). Runs at activation **and** on every per-user startup path (`UserContext` build, remount) via `mcp::prepare_local_connector`, so a fresh container installs from scratch, an updated connector re-installs, and an unchanged one is a hash-match no-op. Deps are therefore **never vendored** — connectors ship `package.json`/`requirements.txt`, not `node_modules/`. Authoring contract for connectors lives in `CONNECTOR_MANIFEST_GUIDE.md` (repo root).
-
-**Connector versioning.** `mcp_catalog` carries `version` (INTEGER — the update-comparison key), `version_string` (semver, display) and `version_release_date` (ISO, display), snapshotted from the feed on install. The marketplace list computes `update_available` = feed `version` > installed `version` (strict) and surfaces it as an "Update" button (`marketplace.js`). The integer is the UI signal; the actual re-install trigger is the reconciler's content-hash.
-
-### OAuth per-user connectors (blueprint §15 — copy-paste flow)
-
-OAuth2 authorization-code + PKCE is wired for per-user connectors (Gmail is the first). The consent is a **human copy-paste**, not a headless action: no callback route into the (NAT'd, hostname-less) box, and no client secret on the public feed.
-
-- **Providers, not per-connector URLs.** The client is per-**provider** (one Google app covers Gmail/Calendar/Drive): `oauth_providers` holds `auth_url`/`token_url`/`client_id`/`client_secret`/`redirect_uri`/`extra_params`, admin-entered via the Sign-in-providers modal (Google preset fills all but the two secrets; `redirect_uri` = the static `oauth/show.html` page, `extra_params` = `access_type=offline`+`prompt=consent` so Google returns a refresh token). The manifest only names `auth.provider` + `auth.scopes` + `auth.deliver` — never URLs or secrets (feed is remote data, §14).
-- **Flow** (`mcp/oauth.rs`): `activate` on an OAuth catalog entry persists a **pending** `mcp_user_servers` row (files installed, command wired, no token) and returns `needs_oauth` — it does **not** start the server. `/mcp/oauth/start` builds the consent URL (PKCE S256 + opaque `state`) and stashes the verifier in a RAM-only, TTL'd flow store keyed by `state`; the user approves in a browser, the provider lands the code on `oauth/show.html`, they paste it back. `/mcp/oauth/complete` exchanges code+verifier for a refresh token (`client_secret` sent server-side), stores it in the row's `api_key`, flips to `ready`, and starts the server. PKCE makes an intercepted code worthless; a restart drops in-flight flows (mirrors the RAM-only session model).
-- **Credential delivery = env, nothing on disk.** The manifest's `deliver` (`{as,format,env}`, parsed as `mcp::DeliverSpec`) says how the token reaches the server. `user_row_spec_resolved` assembles the credential (`google_authorized_user` JSON = client creds from the provider + refresh token) and injects it as an env var (`GMAIL_CREDS_JSON`) on the `docker exec` — never a file, coherent with §2 (the tempted admin doesn't read `/proc`). The server reads it via `Credentials.from_authorized_user_info`. Ran both at OAuth-complete and at login-time per-user startup.
-- **Google needs a Web-application client**: a Desktop client rejects an `https://` redirect (loopback only), so the `oauth/show.html` redirect must be registered on a **Web app** OAuth client, and exact-match under Authorized redirect URIs — `redirect_uri_mismatch` otherwise.
-
-### QR / interactive device login (blueprint §15 — polling flow)
-
-For a per-user connector whose credential is produced by **pairing** (`auth.type: "qr"`; WhatsApp is the first, on Baileys — the slim `skald-runtime` image has no Chromium, so a browser-based client is out), there is no code to paste and the server must **run** to produce the QR. The seam is a generic tool contract, reusable for future device kinds (SSH…):
-
-- **`login_status` tool contract.** A connector needing an interactive login exposes one tool, `login_status`, returning JSON `{state, qr?, message}` (state: `connecting|need_scan|ready|logged_out`; `qr` is a data-URL PNG only while `need_scan`). Skald calls it **directly, never the agent**.
-- **Flow.** `activate` on a `qr` entry inserts a **pending** `mcp_user_servers` row and **starts** the server (unlike OAuth, which defers), returning `needs_login`/`login_kind:"qr"`. `/mcp/login/status` ensures the server is running (restarts a pending one), calls `login_status`, and returns its state; on `ready` it flips the row's `auth_state` so `all_startable` picks it up next login. `/mcp/login/reset` calls the connector's `logout` tool to re-arm (link a different device). The `connector-detail.js` QR panel polls `login/status` and renders the QR.
-- **Credential = on-disk session, not a token.** The connector persists its session inside its own dir (e.g. `./auth/`), under the bind-mounted home so it survives a container recreate — the honest §4 gap (admin-root-readable), not `memory_docs`.
-- **Node 18 gotcha**: the container ships Node 18; Baileys uses the Web Crypto global, so the server must `globalThis.crypto ??= require('crypto').webcrypto` or it dies pre-QR with "crypto is not defined".
-
-**Deferred:** SSH and other §15 device kinds (would reuse the `login_status` contract), `deliver.as=file`, and non-Google OAuth providers are unimplemented paths that error clearly rather than half-work. No boot seed of catalog presets; the admin populates the catalog from the Marketplace.
-
-## Default access — the grant tables are deny-by-default, but the rows are written for you
-
-`plugin_access`, `mcp_global_access` and `mcp_catalog_access` still mean exactly what they meant: **a row is access, its absence is none, every read fails closed**. What changed is who writes the rows. Installing something used to leave it granted to nobody, so the admin then walked the user list; now `db::access_defaults` grants it to the household at the moment of installation and the admin's remaining job is *removal*.
-
-**The default is materialized, never evaluated.** The tempting alternative — leave the junctions lazy and answer each check as `COALESCE(grant.allowed, object.grant_by_default)` with signed rows for exceptions — needs no seeding but costs two things worth more. The checkbox loses a state (an unticked box would mean either "denied" or "inheriting", indistinguishable to the admin), and "who has what" stops being one query: the gate, the plugin roster and the user checklist all read the same junction today, and `plugin_access.plugin_id` is bare TEXT with no `plugins` row to join a default against. So the default is applied at exactly **two moments** and never again:
-
-| moment | seam | what fires |
-| ---- | ---- | ---- |
-| an object is **created** | `access_defaults::seed_new_object` | `PluginManager::update_config` (first toggle — the `plugins` row's birth), `mcp::global_enable`, `mcp::catalog_upsert`, `marketplace` install |
-| a user is **created** | `access_defaults::seed_new_user` | `UserManager::register_user` — in the core, so no future user-creation endpoint can forget it |
-
-**Not on enable/disable**, and that is the load-bearing part: re-enabling a plugin must never resurrect a grant the admin took away, so the trigger is the row's *birth*, not its flag. Every call site therefore checks existence **before** its upsert (`is_new_row` / `is_new_server` / `is_new_entry`) — a re-install or an edit seeds nothing. Seeding is additive-only and idempotent on the PK, which is why every call site is best-effort (a `warn!`, never a failed request): a grant that did not get written is fixable from the user's page, and nothing here can ever widen further than the two moments allow.
-
-**Who is included is a role attribute, not a role id** (§0.1): `roles.attrs.auto_grant`, parsed by `RoleAttrs` like everything else there. It defaults to **`true`** — hence the hand-written `impl Default for RoleAttrs`, since a derived one would give `false` and silently invert the feature for every role predating the attribute. The seeded `children` preset sets it to `false`, which is the whole reason the attribute exists. `admin` answers `false` too, but as a *skip*, not a denial: admins hold everything implicitly (`plugin_access::effective_access` short-circuits), so rows for them would only be noise in every roster. Editable in the role editor (`roles-page.js`, which persists only the opt-out).
-
-**Per-object opt-out** is `grant_by_default` on `plugins` / `mcp_global_servers` / `mcp_catalog` (additive via `ensure_column`, default 1). One thing sets it today: a binding-managed plugin (`Plugin::manages_own_access`, mobile-connector) is marked `0` at row creation, because it never reads `plugin_access` and rows for it would make its roster claim an audience that means nothing. There is no UI for the flag yet — `access_defaults::set_grant_by_default` is the seam when one is wanted. Changing it is deliberately **not** retroactive in either direction.
-
-**A role change does not re-seed.** Promoting a child to an adult role leaves their grants as they were; the admin ticks the boxes once on that person's page. Deliberate: the reverse (demotion) would then have to *revoke*, and a revocation that fires as a side effect of an unrelated edit is exactly the class of surprise the two-moment rule exists to avoid.
-
-## System agents (event triage, memory lints)
-
-A **system agent** runs on a user's behalf without being asked. There are three — event triage (the background event processor) and the two memory lints — behind **one** scheduler, and the machinery is deliberately shaped so a fourth is a trait impl plus one line in a registry.
-
-**The unit of work is one agent for one user**, and every part of the design falls out of that. the triage agent's events (`mcp_events`) are in the caller's own encrypted database, pushed there by connectors in the caller's container; the notification goes to the caller's hub; the trace (`system_agent_runs`) is in that same file. So an agent owns **no timer and no user list**: it implements `SystemAgent` (`crates/skald-core/src/system_agents/`) — `has_work` + `run` over an `AgentRunCtx` unpacked from that user's `UserContext` — and `skald::wiring::spawn_system_agents` decides who and when. Building it against the ownerless `Conversation` bundle was exactly what made the pre-multi-user version inert: it wrote sessions into `system.db`, notified a hub with no subscribers, and resolved tool paths against a container that does not exist.
-
-**One loop for cadences three orders of magnitude apart.** Event triage runs every few minutes, a lint weekly — the case that tempts a second loop. It stays one because the wake-up decides nothing: `base_tick` (min enabled interval, clamped to [60s, 15min]) only picks how often to *look*, and whether an agent runs for a given user is `system_agents::is_due` against persisted state. A second scheduler would be a fourth global bus in disguise.
-
-**Due-ness is persisted, not counted from boot** — the new owner table `system_agent_state(agent_id, last_attempt_at)` (accessor `db/system_agent_state.rs`). It is deliberately **not** `system_agent_runs`: the run log is a history for the human and skips idle ticks, while scheduling needs *every* attempt, so reading due-ness off the log would re-run an idle agent every tick and never bring a weekly one due once its last productive run aged out. Persisting it is also what makes a long interval survive a restart — an in-memory deadline is fine at event triage's scale but a weekly agent on a box rebooted every few days would have it re-armed before it ever fired, and would simply never run. Side benefit: a user who logs in after a long absence is picked up on the next pass.
-
-**`run_and_record` orders the three steps, once, for everybody**: mark the attempt (always, even for an idle pass) → `has_work` (`false` writes nothing at all, or the run log becomes a heartbeat) → open the run row, then work. The `start`/`finish` split (unlike `job_runs`, written once at the end) leaves a visible `running` row when the process dies mid-pass, swept to `failed` by the next `start` for that agent — safe precisely because the scheduler is sequential and single-instance, at both levels (agents in order, then users in order).
-
-**`AgentScope::PerSubject` is the scope where "whose data" and "whose runtime" come apart** — the conversation review (`system_agents/conversation_review.rs`, wiring `subject_pass`) is the first and the reason it exists. The pass reads the **subject's** database and runs inside a **supervisor's** runtime, so everything it leaves behind (ephemeral session, run row) lands in the watcher's file and nothing in the watched one's; the report crosses between them via `system.db`. Three things fall out and each is load-bearing: (a) **iteration is over subjects, not supervisors** — two parents watching one child must yield one review, so whichever of them is unlocked lends a runtime and the report is filed against the subject; (b) **`is_due` is not consulted** — it keys state by agent within one file, which would collapse every subject sharing a supervisor into one clock, so due-ness lives in `system_agent_coverage` and is answered inside `has_work` (and `run_and_record` skips `mark_attempt` for this scope for the same reason); (c) **the subject need not be logged in**, via the new `UserManager::open_unencrypted` — for a user with no key the password guards the *session*, not the data, so this makes that explicit in one place and **refuses an encrypted user**, not as policy but because there is no key to be had. The rule that falls out is neutral by construction and worth quoting: *work over somebody else's history runs unattended for a user who is not encrypted, and only while they are logged in for one who is*. The returned pool is deliberately **not** registered as unlocked (that map is what "logged in" means to everything else). Authorization is the caller's: `subject_pass` is behind the `supervision` edge, never a role check.
-
-**`meta.json: "allow_tools": false` empties the turn's tool set** (`AgentMeta::allow_tools` → `loop_adapters/runtime.rs::turn_params` swaps in an empty `ToolRegistry`): built-ins, MCP, plugin and interface tools alike, `notify` included. Distinct from a restrictive security group — a group decides whether a call is *allowed*, this decides whether the model is shown anything to *call*. For an agent whose input is other people's text, that is also the prompt-injection answer: the round an injected instruction would act in has no tools in it. The conversation review declares it, and consequently produces its report as the turn's **final assistant message** (read back with `chat_history::last_assistant_for_session`, parsed shallowly by `parse_report`: leading `# heading` → title, opening paragraph → summary, `NOTHING_TO_REPORT` sentinel → no row) rather than through a `save_report` tool, which would have needed whitelisting past the approval gate that an unattended pass auto-denies. The cost is that severity cannot come from the model; every report it files is `notice`.
-
-**Per-pass prompt substitutions.** `run_ephemeral_turn` takes a `system_substitutions` map. The two the system context resolves by itself (`__USER_PROFILE__`, `__SHARED_FOLDERS__`) describe the *session owner*, which for a pass about somebody else is the wrong person — so the review passes the **subject's** profile under its own `<!-- SUBJECT_PROFILE -->` key (rendered by the shared `loop_adapters::system::render_user_profile_section`). It goes in the system prompt rather than the trigger message because age, name and sex change what counts as worth reporting, and the model needs them before it reads a word of the transcript.
-
-**A locked user is skipped, and that is the normal case, not an error.** The pool is the unlock token (§9): a user who has not logged in since the last restart has no readable events, no session store — and no place to record the skip, since the only file that could hold it is the one we cannot open. Hence `system_agent_runs` has no `skipped` status: the skip is an INFO log line and nothing else.
-
-**`AgentScope::Instance` is the ownerless-work escape hatch, and there is exactly one user of it.** The shared memory store belongs to nobody, but a pass over it still has to run *somewhere*: an ownerless run would write its trace into `system.db`, which `GET /api/system-agents/runs` shows to nobody (scoped on the caller's own pool, by design), and its `notify()` would have no recipient. So `instance_pass` runs it as the **first active unlocked admin** (`users::list` order, so the choice is stable across passes), and the whole per-user surface keeps working unchanged. Cost: it needs an admin who has logged in since the restart.
-
-**The run log is theirs, not the admin's** (`db/system_agent_runs.rs`, owner table, no `user_id` column — the file is the owner). `GET /api/system-agents/runs` is scoped through `require_context` with **no admin override**: everyone, admin included, sees their own runs. `stats` is a JSON blob of the agent's own counters, never contents.
-
-**The configured security group is not applied verbatim.** `<agent>.security_group` is an instance-wide admin setting; handing it to a restricted member's run would give their background agent a tool set their role never granted. `system_agents::configured_run_context` puts it through `run_context::reconcile_group_for_user` — the same seam a persisted group takes — degrading to the role default when the role disallows it. With nothing configured the run still starts from `role_default_run_context`, never `None`, because `None` means the catch-all group, which is *wider*.
-
-### The conversation review
-
-`system_agents/conversation_review.rs` — nightly, one report per supervised subject, covering **every** conversation in the window rather than one report per session (the useful signal is often *across* conversations). The window is `[covered_through, now)` and due-ness is "the watermark stops before the most recent occurrence of `run_at_hour` local" (default 4am), which is also why downtime needs no catch-up mechanism: a machine off for three days finds a three-day-old watermark and covers it in one pass. `most_recent_occurrence` is generic over the timezone so it is testable without depending on where the box is, and resolves through the timezone (not UTC arithmetic) so a DST-skipped hour is handled.
-
-`chat_history::conversation_window` is the transcript query, and its four filters each exist because of a specific way the result would otherwise be wrong: `is_ephemeral = 0` (or a pass reads the transcript its *previous* pass was given and reports on itself), `depth = 0` (sub-agent frames are machine-to-machine), `is_synthetic = 0` (machinery-injected turns are not things the person said), `content <> ''` (an assistant row that was only a tool call). **Tool calls are absent by construction, not by filter** — they live in `chat_llm_tools` — so the review sees what was *said*, never what was *done*, and the prompt says so plainly because a model shown a gap narrates over it. Rendering is prose grouped by conversation, never JSON: a dialogue read as a dialogue is what models are best at, and nothing machine-readable comes back this way — the structured artefact is the report at the other end.
-
-### The memory lints
-
-`system_agents/memory_lint.rs` — one struct, two instances differing only by fields: `MemoryLintAgent::private` (`PerUser`, over `user-memory/` in the caller's pool) and `::shared` (`Instance`, over `shared-memory/` in the system pool — the same routing `classify_memory` gives the fs-tools). Prompts are two `AGENT.md`s sharing `agents/common/memory-lint.md`; the shared one additionally hunts **table-rule violations** and is told to report *which note and what kind of problem* without repeating the sensitive line, since restating it is the harm being flagged.
-
-**Read-only, enforced twice.** The prompt says report-never-repair, and `shared-memory/*` writes are already `@fs_write require` — so an agent that tried to fix something would raise an approval card from an unattended pass, which `run_ephemeral_turn` auto-denies. Read-only is not a convention here, it is the only thing that works. `has_work` is "the store is non-empty", so a member who never uses memory collects no weekly row and no weekly notification.
-
-**Interval units are per-agent**: event triage in minutes, the lints in days (`interval_from_config` takes the unit). Asking an admin to type `10080` for "weekly" would be a worse version of the same field.
-
-### Where the settings live
-
-`ConfigSet` gained `owner: Option<String>` (core-api): `None` renders on the general Config page, `Some(agent_id)` is claimed by the surface that owns it. Placement is **data on the set**, not a filter that knows set names, so a new owned set lands in the right place without touching either page. `system_agents::registry()` and `::config_sets()` are the single enumeration of the agents — `registry_and_config_sets_agree` is the test that stops the scheduler's list and the settings surface from drifting.
-
-`/api/config` serves only owner-less sets and is now **admin-gated** (`caps::require_admin`), read *and* write: before this, both handlers ignored the caller entirely, so any authenticated session could read and change instance config — the sidebar hiding the page is presentation, not authorization. `GET /api/system-agents` lists the agents, with `config` resolved (via the shared `config::render_sets`) only for an admin and `Value::Null` for everyone else; writes still go through `PUT /api/config/{key}`, so the gate and the known-key check exist in one place.
-
-UI: `#system-agents` (`web/components/system-agents.js`, sidebar group `extensions`, **visible to everyone** — the run log is the caller's own). **One tab per agent, plus "All"**, each tab holding that agent's description, its settings (admin only) and its runs — the tab is the agent, not the kind of information, because "why did this do nothing last night?" is half a schedule question and half a log question. The settings form is `web/components/shared/config-form.js` (`ConfigFormController`), shared with `config-page.js` so an owned set renders identically wherever it is edited. It replaced a since-removed debug page (`#tic`, from when the triage agent was called TIC), which listed `chat_sessions WHERE source='tic'` and so inferred runs from leftover ephemeral sessions rather than recording them.
-
-## Multimodal attachments
-
-Uploads go through **one centralized seam** — `ChatHub::save_upload` (behind `ChatHubApi::save_upload`, backed by `skald_core::uploads::save_to_home`) — so every surface persists identically and no two callers can drift on placement (the class of bug where the agent was handed a path it couldn't reach). The seam writes into the **caller's container home** under `uploads/{session_id}/` (agent path `uploads/{session}/{name}`, the `UPLOADS_SUBDIR` const in `core-api/user_fs.rs`), collision-dedupes the name, and prefers the sniffed magic-byte MIME over the client claim. The **web** handler (`POST /api/{source}/uploads`) buffers each field with a 256 MiB cap then calls the seam; the **Telegram** plugin downloads bytes then calls the same seam via `handle.chat_hub().save_upload("telegram", …)`. Because the file lands in the home (bind-mounted at `/root`), it is reachable by the fs-tools, `execute_cmd`, and the file viewer (`GET /api/file`, per-user via `resolve_view_path`) — there is **no** `/data` static route anymore (removed: it was `require_auth`-only, not ownership-scoped, and also exposed internal server state under `data/`). Attachment metadata travels as structured JSON in `chat_history.metadata` — never as persisted text.
-
-At context-build time (the crate's projection), attachments of the **current turn** (the user/agent rows following the last completed assistant reply, including across in-flight tool rounds) are partitioned by `agent_loop::projection::media`, with `loop_adapters/media_source.rs` deciding **which** files may be handed over (§6 containment): when the resolved model's `LlmEntry.capabilities` include the modality (`vision` → `image_url` parts, `video` → `video_url` parts), the file is inlined as a base64 data-URL content part — but only if it resolves (through the caller's `UserFs`, via `resolve_host_path`) under the home's `uploads/` dir, its sniffed MIME is in the allowlist, and it fits the budgets (4 files / 10 MiB image / 32 MiB video / 48 MiB total per turn). Everything else — older turns, other kinds, any failed check — keeps the textual `<system-extra>` path block (built by `core_api::message_meta::attachments_block` / `system_extra`; the tag name is the single `SYSTEM_EXTRA_TAG` constant), so a non-vision model produces a byte-identical payload to before. `OpenAiClient` forwards parts verbatim; `AnthropicClient` translates `image_url` data URLs to `image` blocks (video unsupported; Anthropic models get `vision` by editing the model row's capabilities — no catalog refresh writes them). On LLM fallback mid-round, messages are rebuilt with the replacement model's capabilities.
-
-## Token streaming & reasoning display
-
-The chat streams tokens live, as a **parallel best-effort side-channel** that never alters the turn's authoritative flow: the final `Done` (or `Thinking`) event still carries the complete content and the frontend treats it as truth.
-
-- **Client seam** (`core-api::chatbot`): `ChatbotClient::chat_with_tools_raw_streaming(..., delta_tx: mpsc::Sender<StreamDelta>)` — default impl ignores the channel and calls the buffered `chat_with_tools_raw`, so providers without streaming (Ollama, LM Studio) are untouched. `StreamDelta::{Text, Reasoning}` splits visible answer from chain-of-thought. Senders use `try_send` (deltas drop when the channel is full) — streaming must never backpressure the HTTP read.
-- **SSE implementations** (`crates/llm-client`): `OpenAiClient` (`stream:true` + `stream_options.include_usage`, `reasoning_content`/`reasoning` deltas, index-based `tool_calls` accumulation, usage from the final chunk) and `AnthropicClient` (`stream:true`; `message_start`/`content_block_*`/`message_delta` events; `thinking_delta` → reasoning, `input_json_delta` → tool input). Both reassemble the **same `LlmTurn` + `LlmRawMeta`** the buffered path returns (the payload log stores a synthesized buffered-shaped body). Failure policy: if the stream dies **before any delta** the client retries buffered on the same model (providers rejecting `stream` keep working); a mid-stream failure propagates to the normal model-fallback logic. Framing is shared (`llm_client::SseDecoder`). Anthropic's **buffered** path now also parses `thinking` blocks into `reasoning_content` (previously discarded).
-- **Loop wiring**: `call_llm_round` creates the delta channel per attempt and a forwarder task maps deltas to `ServerEvent::TokenDelta { kind: content|reasoning, delta }` on the turn's event channel (drained before the round's outcome events, so ordering holds); cancellation drops the in-flight future as before. A mid-stream fallback is handled client-side: the frontend clears its pending bubble on `model_fallback`.
-- **Reasoning surfacing**: `reasoning_content` rides `Done`/`Thinking` events (so buffered providers show it live too) and is projected as `reasoning` on assistant/thinking history items (`build_items`); persistence in `chat_history.reasoning_content` and the echo back into context predate this feature.
-- **Frontend** (`chat-session.js` + `copilot-render.js`, shared by desktop copilot and mobile chat-page): `token_delta` accumulates into a pending assistant bubble (in-place mutation + ~15 Hz flush, blinking caret); `done`/`thinking` finalize it in place, `error`/`llm_failed`/`model_fallback` drop it, `tool_start`/`agent_done` finalize orphan bubbles (reasoning-only rounds, sub-agent final rounds that emit no `Done`). The reasoning block is a muted, collapsed-by-default native `<details>` (`renderReasoning`, `.reasoning-block` in `copilot-messages.css`, i18n key `chat.reasoning`) — open state survives re-renders, and it renders identically from live events and from history.
-
-## The LLM loop (`agent-loop`)
-
-The loop is a **standalone crate** (`crates/agent-loop/`) that knows nothing about Skald: it owns control flow (rounds, model fallback, tool fan-out, recording), the projection of history into wire messages, sub-agent delegation, restart recovery and compaction. Skald supplies content through the traits in `crates/skald-core/src/loop_adapters/`. Nothing in `session/handler/` shapes a `Value` anymore — there is exactly **one** projection in the workspace.
-
-**One `LoopManager` per user** (`UserLoopRuntime`, `loop_adapters/runtime.rs`, blueprint D12), built by `ChatSessionManager`: it owns the event bus, the live-loop registry (which conversations are running, `/stop`, recovery, shutdown), the store, the approval gate, the hooks, the agent catalog and the delegate tool. A turn contributes only what is its own — the agent's prompt, its tool set, its model pin — via `turn_params`.
-
-**Per-turn state rides the `Extensions` type-map** (`loop_adapters/scope.rs::TurnScope`): the gate and the catalog live as long as the user, so they cannot capture a session id or a permission group — they read the turn's scope from the call's extensions. **A call with no scope is denied**, never run with permissive defaults.
-
-Three entry points, all in `session/handler/kernel_turn.rs`:
-
-| entry | when | what it does |
-| ---- | ---- | ---- |
-| `run_kernel_turn` | a user message | repairs a dangling call from a crashed turn, then `manager.start_turn` |
-| `recover_turn` | WS connect, async result delivery, background wake-up | `Recovery::run` — no new message, continue what was interrupted |
-| `resolve_pending_call` | an approval answered after a restart | run the call with the gate skipped, then continue |
-
-The event **translator** (`loop_adapters/translate.rs`) is the ONE bus subscriber turning `LoopEvent`s into the session's `ServerEvent`s; byte-parity with the pre-kernel event sequence is its contract.
-
-### Sub-agents
-
-- A sub-agent is a **tool**, not an interception: `DelegateTool` (registered under the legacy names `execute_task` / `execute_subtask`, D11, each keeping its exact legacy schema) opens a child frame and runs a normal loop in it. The parent simply awaits a slow tool call. Max depth `MAX_AGENT_DEPTH = 5`.
-- **Parallel batches are the kernel's generic fan-out**: a round whose calls are all `concurrency_safe` (a sync delegate is) runs concurrently, bounded by `max_parallel_calls`. The ordering invariant is unchanged — ids allocated in call order (phase 1) → concurrent execution (phase 2) → recording in call order (phase 3) — so the model reconstructs results by id. Any mixed batch stays sequential. Siblings share the session scratchpad; concurrent writes to the same key are last-writer-wins by design.
-- `mode: "async"` submits a durable `scheduled_jobs` row through `loop_adapters/async_task.rs::CronExecutor` and returns a receipt immediately; when the job finishes, `DurableSink` writes the result into the parent conversation (synthetic assistant + a completed `task_completed` call) and resumes it. `mode: "cron"` is scheduling, not delegation, and stays on the cron interface tool.
-- **An async task ends in the conversation that started it, whatever happened to it** — and `cron::run_job` is shaped so it cannot do otherwise: one `JobOutcome` classification, then *one* `match job.kind` delivery site for every ending. It used to branch on `Ok`/`Err` first and route by kind only inside `Ok`, so a failure or a kill went out as a "Cron job … failed" notification to the **home** source (`/sethome`) while the parent sat waiting for a `task_completed` that never came — the wrong chat *and* a wedged conversation. The sink has a single channel by design: to the model, "it broke" is a result like any other and must not be overlookable, so the failure is delivered as prose (with whatever partial output the run produced). A cron job has no parent conversation and keeps the home notification — the future plan is to let its creator name a destination. Cancellation is a third outcome, not a flavour of failure: `job_runs.status` always had `'cancelled'` in its CHECK and nothing wrote it, and the classifier keys on the **typed** `session::handler::TurnCancelled` error, never on the message text.
-- **The chat shows what it started.** `ServerEvent::TaskUpdate` announces an async task's state to the source of its parent conversation only (a cron job belongs to nobody's chat), and `GET /api/{source}/tasks` (`db::scheduled_jobs::list_for_parent_session`) answers the same question at load time — running tasks plus failures from the last 30 minutes, because the event is a broadcast with no replay and a browser reload would otherwise empty a chat that still has work under it. Successes are absent from that query on purpose: a finished task's result is already a message in the conversation. The strip itself is `web/components/shared/agent-tasks.js` (`renderTaskStrip`), rendered above the composer on desktop and mobile from state owned by `ChatSession`; the drill-in is `#session/{id}`, gated on `_canOpenTaskSession` because the mobile shell routes a fixed set of sections and would silently swallow that hash.
-- A child's model is **never inherited** from the parent: passing a concrete name would bypass AUTO selection, so sub-agents auto-select unless explicitly overridden (`args.client` → `meta.json client` → AUTO by strength).
-- `list_agents` returns **task** agents only (never `chat`/`system` ones like the entry agent).
-
-### Restart recovery (`agent_loop::recovery`)
-
-A crash loses RAM (the approval oneshot, the cancellation token), never truth: every state transition is a store write. So recovery does not have a mode of its own — it makes the history well-formed and then runs a **normal loop** on it:
-
-1. **Reap** an interrupted parallel batch (≥2 active frames at one depth is impossible for a linear stack): fail their spawning calls, close the frames. Deliberately lossy.
-2. **Resolve** the deepest frame's non-terminal calls. A `Running` one is re-gated and re-executed **unless the tool says otherwise** — `execute_cmd` declares `RestartHint::MarkInterrupted` (D7), because a command may already have had its effect. An `AwaitingHuman` one is re-asked (the card reappears).
-3. **Un-wedge**: a child that finished but whose result never reached its parent propagates without calling the model again.
-4. **Cascade** to the root, resolving each parent call with its child's result — every frame running as **its own** agent, from the catalog, never the root's (B3).
-
-`Cancelled` and `Rejected` are terminal and are never re-executed. Anti-double-driving goes through the manager's registry (a recovery claims the conversation like a live turn), not a host-side flag.
-
-## Cancellation (stop)
-
-- The turn's `CancellationToken` is minted by `LoopManager::start_turn` and **cloned by value** down the whole call tree; a delegate passes `ctx.cancel.child_token()`. It is never re-read from a field mid-turn, which is what makes `/stop` **sticky** across sub-agent recursion.
-- `ChatSessionHandler::cancel()` → `manager.cancel(&conversation)`. The token is checked at each round boundary and before each tool call, wrapped around the in-flight LLM call (`tokio::select!`, aborting the request), and around `execute_cmd` (dropping the future → `kill_on_drop`). Parent and child share the tree, so a cancelled child stops the parent by construction.
-
-## Compaction
-
-`agent_loop::compaction` owns the mechanics: split point (never between an assistant turn and its tool results), transcript, prompt (`SUMMARY_PREFIX` / preamble / template live there now), the single no-tools model call, the saved summary row. `skald-core/src/compactor.rs` owns the **policy**: the token threshold, the ephemeral guard, which model summarises (`compaction_model` from Settings, else AUTO by `compaction.strength`), and publishing `CompactionEvent` on the chat bus. The DTL re-anchor is the `on_compacted` hook (`loop_adapters/hooks.rs::DtlReanchorHook`). The next turn needs nothing: the assembler reads the latest summary from the store.
-
-### Context size: both automatic guards are off by default
-
-Nothing shrinks a conversation unless a human asks. `llm.max_history_messages` and `llm.compaction.threshold_tokens` are both `Option`, both **unset** in `default.config.yaml`, and the only remaining reducer is the user typing `/compact`. The reason is the **prompt cache**: every provider that caches (Anthropic breakpoints, OpenAI automatic prefix caching) keys on the longest common *prefix*, so anything that rewrites history mid-conversation costs a full miss on the next request.
-
-The two guards are not equally bad at that, and the difference is why one is merely off and the other is close to a trap. `max_history_messages` is a **sliding tail window** (`agent_loop::projection::window` — `drain(..len - max)`): past the cap it drops from the head on *every* turn, so it is a cache miss *per request*, forever, and it drops messages with **no summary standing in for them** — silent amnesia. Compaction rewrites the prefix **once per compaction** and leaves a summary behind. So the previous default — window on, compaction off — was the worse of the two in both dimensions, and the window's own doc-comment already said the two were mutually exclusive.
-
-Three consequences worth not re-deriving:
-
-- **The compactor is built unconditionally**, in both `bundles.rs` and `user_context.rs`. It used to be `Option<Arc<ContextCompactor>>`, keyed on the config section existing — which meant that commenting out `compaction:` also silently disabled **manual** `/compact` (`force_compact` returned `Ok(false)` and the chat answered "compaction disabled"). Manual compaction is a command a user types; it must not depend on an admin having filled in a token threshold. `try_compact` early-returns on `threshold_tokens: None`; `force_compact` deliberately does not consult it — the human *is* the trigger.
-- **The projection yields to the *automatic* pass, not to the compactor's existence**: `LoopConfig.auto_compaction_enabled` (`= ContextCompactor::auto_enabled()`), so a configured message cap is not silently voided by the mere availability of `/compact`. Expressed as `max_history_messages.filter(|_| !auto_compaction_enabled)` in `projection_cfg.rs`.
-- **`CompactionConfig`'s `Default` is hand-written**, same trap as `RoleAttrs`: a derived one gives `keep_recent: 0`, which would compact away every recent message on any box omitting the section — now the shipped default.
-
-The future automatic pass should trigger off the **resolved model's own context window**, not a hand-tuned `threshold_tokens` that has no idea which model is answering.
-
-### The system prefix is frozen per conversation
-
-Same economics, other end of the request. `AgentSystemContext::system_context` is called **once per round**, and it reassembled `base` from disk and SQLite every time — so an agent writing `user-memory/index.md` in round 3 made round 4, seconds later and with the cache certainly warm, a full miss. Since `base` is the head of every provider's cache key, that is the most expensive string in the request to touch. `loop_adapters/prefix_cache.rs::PrefixCache` builds it once per `(conversation, agent)` — the agent is in the key because a sub-agent shares its parent's conversation but has a prompt of its own — and holds it on `UserLoopRuntime`, so it outlives the turn.
-
-The refresh rule is the only one that is free: **rebuild once the conversation has been idle longer than a provider's cache could survive** (`PREFIX_TTL`, 20 min). The clock is therefore *idle time of this conversation*, not time since a file changed, and reading restarts it — every `get` is a request about to go out. The asymmetry that sets the constant: below a provider's window you pay misses that buy nothing, above it you only pay freshness.
-
-**Writes are deliberately not reacted to, and there is no bus variant for this.** When the agent itself edits an injected file the content is already in the context — its tool call and result sit two messages downstream — so refreshing would repeat what the model just said. A write from *elsewhere* (the same user's Telegram session, a cron job, another member editing `shared-memory/`) is genuinely invisible until the TTL: that is the case where an immediate rebuild costs the most, since a conversation that would notice is by definition a warm one, and the cheaper freshness path already exists — the agent can `read_file`, and a tool result *appends*, which invalidates nothing. The injection header says so in words. Cross-user invalidation would need a `SystemEventBus` variant plus a subscriber per user (the writer lives in a different `UserContext`); it is future work, and this type's key is the seam for it. Note `base` is frozen **whole**: freezing the memory files while letting `__USER_PROFILE__` move would invalidate just as much. The cost is that an `AGENT.md` edit lands at the next rebuild rather than the next round.
-
-## Approval gate
-
-The rule engine `ApprovalManager::check` returns `Allow`/`Deny`/`Require` per tool call (default rules seeded on first boot; the catch-all `* require @999999` gates anything not explicitly allowed — e.g. `execute_cmd`, `execute_task`, writes outside whitelisted paths). It is wired to the loop as `loop_adapters/gate.rs::ApprovalGate` (`agent_loop::gate::Gate`). A `Require` registers a `oneshot` in the in-memory `pending` map keyed by `request_id` and emits an approval event over WS.
-
-Resolution is **source-agnostic**: the WS + Inbox paths resolve by `request_id`; the inline chat card resolves by the durable `tool_call_id` via `POST /api/tools/:tool_call_id/resolve` (`resolve_tool` in `src/frontend/api/sessions.rs`), which derives the owning session from the tool call's own stack row — never a hardcoded source. Live pending cards fire the `oneshot`. Post-restart there is **one** path for every tool, `LoopManager::resolve_pending`: the call runs with the gate skipped (the human just decided) but with the session's real `ToolContext` — owner pool, per-user container — so a resolved `write_file`/`execute_cmd` acts on the user's workspace, never the server cwd/host (this was a §6 escape); then the conversation continues, including a sub-agent dispatch, which simply opens its child frame like any other call. The endpoint returns as soon as the work is scheduled and the result streams over the bus.
-
-The **diff preview** in a `PendingWrite` event (`loop_adapters/preview.rs::read_current_content`, driven by the `SkaldWritePreviewHook`) routes exactly like the fs-tools: `user-memory/`/`shared-memory/` → `memory_docs` on the right pool, every other agent path → the caller's host workspace via `resolve_host_path(&self.fs, …)`. It must never use the cwd-relative `fs::resolve` — that showed a bogus "new file" on overwrites (or the diff of a same-named cwd file), so the user would approve the wrong diff.
-
-**Tool visibility in the Security-groups UI** (`GET /api/approval/tools`): tools injected outside the `ToolRegistry` (interface/plugin/provider tools) would otherwise be un-configurable. `ToolCatalog::list_all()` covers registry tools + a static `synthetic_tools()` list of core interface tools; everything else is captured by `crates/skald-core/src/tool_discovery.rs` (`ToolDiscovery`), which taps the tool set the loop offers each round (`SkaldToolSet::defs`) and upserts every offered tool into the `known_tools` table (in-memory seen-set guard → background DB write). `list_tools` merges `known_tools` (deduped, `category: "dynamic"`) so any tool offered at least once becomes gate-able. Drift-proof by construction; core never hardcodes plugin tool names.
-
-## Restart
-
-There is **no in-app restart** anymore. The agent-callable `restart` tool and its `set_restart_handler` seam were removed (blast radius = the whole box: it dropped every user's session and in-RAM DEK from one user's chat — a power-user leftover, out of place in the multi-user model). Nothing in the process now calls `libc::_exit(-1)`.
-
-The supervisor protocol survives but is currently **unreachable in-app**: `run.sh` still re-executes the binary *by path* when it exits `255`, but no code produces that exit code. Restarting is therefore a manual/admin operation.
-
-To pick up `config.yml` / `providers.yaml` / database changes (read only at startup), or to load new **code** (`./build.sh` installs the new binary via atomic rename): stop the server and let `run.sh` loop, or re-run `./run.sh`. A future admin-only restart action (endpoint/button gated by an admin capability) would re-use the `255 ⇒ re-exec` seam — it is intentionally kept for that.

+Create `agents/<id>/meta.json` and `agents/<id>/AGENT.md`. The agent is discovered at runtime (no restart needed for prompt edits). Optionally set `"client": "<name>"` in meta.json to pin a specific LLM.
 
-**The chat is the home page.** `<app-copilot>` is a single persistent element with two layout modes driven by the route (`llm-page-change`): `mode="full"` on the home route (it fills the workspace — the conversation IS the landing page, with a welcome hero + prompt suggestions as its empty state) and `mode="dock"` on every other route (the classic resizable side panel). Same element ⇒ WS, tabs, scroll and drafts survive navigation; you watch files/projects update live while the conversation keeps going. Collapse only applies to the dock. The old dashboard content (hero, LLM stats charts, pending inbox, quick guide) lives on as the separate `#dashboard` page; the debug toggle moved to the Settings page.
+## Restart
 
-**Two kinds of tab, and the difference is what a tab names.** A **primary** tab is a *source*: it shows whatever `web` / `project-7` currently points at (`sources.active_session_id`), which is also where background delivery lands — `notify`, a finished async task, an inbound Telegram message — and what a `/new` moves to a fresh row. At most one per source; a project's **Open chat** always lands on it and never mints a conversation (`provision_session(reset:false)`). A **secondary** tab is one specific conversation, opened with `+`: its source points elsewhere, so it is **unreachable by source name** and is addressed by id everywhere — REST, WebSocket, event filtering. Nothing is delivered to it from outside. `POST /api/sessions/new` creates one *without touching `sources`*, which is the entire difference from `POST /api/sessions` (a reset). Its agent and run-context still come from the source, so an extra project tab is the coordinator with the project's context.
+There is **no in-app restart** anymore. The agent-callable `restart` tool and its `set_restart_handler` seam were removed (blast radius = the whole box: it dropped every user's session and in-RAM DEK from one user's chat — a power-user leftover, out of place in the multi-user model). Nothing in the process now calls `libc::_exit(-1)`.
 
-**The queue and the model pin are keyed by conversation, not by source** (`ChatHub.inboxes: HashMap<i64, ConversationInbox>`, `selected_clients: HashMap<i64, String>`). This is the load-bearing half: two tabs on one source would otherwise serialize into one queue and one turn, and share a `/model` pin — while the *security group* was already per-session and persisted, so the pin was the odd one out. The source-taking methods survive as one-line resolvers (`send_message` → `send_message_to_session`, and `_for_session` twins for context/cost/compact/mcp/model/cancel/resume/upload), so Telegram, mobile and cron are untouched. Cost of the rekey: queues now grow with conversations-talked-to-since-boot rather than with the four-or-five sources, so a reset **retires** the queue it replaces (`retire_inbox` → `ConversationInbox::close`, consumer breaks) instead of leaving a parked task forever.
+The supervisor protocol survives but is currently **unreachable in-app**: `run.sh` still re-executes the binary *by path* when it exits `255`, but no code produces that exit code. Restarting is therefore a manual/admin operation.
 
-**Events are filtered per conversation** (`ge.session_id == Some(session_id)`), which is why anything a chat must see has to carry a session id — an untagged `GlobalEvent` now reaches nobody. Two emitters had to be fixed for exactly that: `show_file_to_user`'s `OpenFile` (the tool takes a `session_id` from `handler.session_id` via the interface-tools builder) and `revalidate_security_groups`, which now returns `(session_id, source, group)`. The inbox lifecycle events (`Approval*`/`Clarification*`/`Elicitation*`) stay the deliberate exception and go to every connection, since they carry ids only and drive the sidebar badge. A **primary** WS connection additionally follows `NewSession` for its source — re-binding `session_id` and its handler mid-loop — so a second window doesn't keep talking to a conversation another window just reset; a session-addressed one ignores it, having been pinned on purpose.
+To pick up `config.yml` / `providers.yaml` / database changes (read only at startup), or to load new **code** (`./build.sh` installs the new binary via atomic rename): stop the server and let `run.sh` loop, or re-run `./run.sh`. A future admin-only restart action (endpoint/button gated by an admin capability) would re-use the `255 ⇒ re-exec` seam — it is intentionally kept for that.
 
-**The tab bar is server-side state; the selection is not.** Which conversations the copilot shows survives a reload through `chat_sessions.is_open` (owner table, additive via `ensure_column`) — `GET /api/sessions/open` restores them (computing `primary` per row, since only `sources` knows), `PUT /api/sessions/{id}/open` opens/closes one, `PUT /api/sessions/{id}/title` renames one (`title` predated all this and was dead; an empty title stores `NULL`, so the rename box is also the undo). It is deliberately *not* localStorage: that store is per-origin, so on a shared laptop one member's tabs would greet the next, and in the user's own encrypted file the set follows them across devices instead. **Which** tab is selected stays in `sessionStorage` (`copilot-active-tab`), because that one is per browser window — a shared value would have two windows fighting over it and turn every tab click into a write. Three consequences that are easy to get wrong: (a) `is_open` defaults to **0** and `chat_sessions::create` never sets it — every `/new` leaves its predecessor behind and every system-agent pass mints a row, so `DEFAULT 1` would restore a bar full of conversations nobody opened; only the copilot writes the column. (b) The General tab is never stored — it exists because the copilot exists. (c) A reset **moves** the flag: `provision_session(reset)` mints a new row, so `POST /api/sessions` returns the new id and the `new_session` event carries it, and `_bindTabSession` closes the old row as it opens the new one — leaving both would restore the source twice and let a later close clear the stale one. Restoring the selection happens *before* `super.connectedCallback()` (sessionStorage is synchronous) so the first paint doesn't fetch General and throw it away; the set arrives over the network and reconciles after, awaiting the base's initial connection so it never opens a second WS.
+> `run.bat` is still stale (`cargo run`) and must be fixed.
 
-**Theme** (`web/css/variables.css`): warm "paper" palette (terracotta accent, light by default, warm-charcoal dark), generous radius (`--radius-sm/md/lg`), 16px-base chat type, WCAG-fixed contrasts, global `:focus-visible` ring and `prefers-reduced-motion` support. Everything consumes CSS variables — never hardcode a hex in a component stylesheet.
+## Documentation
 
-**i18n** (`web/lib/i18n.js` + `web/i18n/{en,it,fr}.js`): `t(key)` helper, `I18nMixin` re-renders on `locale-changed`. Resolution order: user preference (`users.locale`, editable on the profile page) → instance default (registry config key `ui_locale`, editable by the admin in Settings — declared in `skald_core::i18n::config_set`) → English. **Server-side, never re-implement that chain**: `skald_core::i18n::resolve_locale(pool, user_locale)` is the one function (with `default_locale(pool)` and `language_name(locale)` for prompt rendering); they read through `db::config` because the bus only matters for writes and callers like the system-context source hold pools, not the manager. Pre-auth screens use the localStorage cache. Default locale is English. First-run setup asks the language in both shells — the console wizard writes `ui_locale` via `skald_core::i18n::set_default_locale` (no system bus exists there), the web setup page sends `locale` to `POST /api/setup/user`, which writes it through `GlobalConfigManager::set`. Supported locales are centralized in `skald_core::i18n::SUPPORTED_LOCALES` and enforced server-side on every write. Translated so far: chrome (sidebar/topbar), chat + approval cards, login/setup, profile, inbox; deep admin pages are still English (fallback is automatic per-key). Copy is the only place domain words may appear (§0.1).
+`docs/` is **not developer documentation** — it's written for the in-app LLM, not for a human reading the repo, and is mounted read-only into every user's container at `~/docs/` (see [`dev-docs/filesystem-and-containers.md`](dev-docs/filesystem-and-containers.md): `docs_host` on `UserFs`, `DOCS_DIR` in `container/mod.rs`). It explains the software's UX (plugins, and eventually agents/connectors/memory/roles/…) in plain terms, in English, so the assistant can help a non-technical user configure things instead of guessing. `docs/index.md` is the entry point (general index of feature pages); `docs/plugins/<plugin id>.md` covers each built-in plugin. The three `type: chat` agents (`assistant`, `kid`, `project-coordinator`) are told in their `AGENT.md` to read `docs/index.md` when a user asks how the software works. **Standing rule: every change that impacts the UX must update `docs/` in the same change** — a new/renamed feature page plus the `docs/index.md` index entry. It goes stale like any other doc, except users actually see this one.
 
-**Plugin & backend i18n** — two seams, both keyed the same way. A plugin **page fragment** (served from its own router) localizes client-side: it ships a `web/i18n.js` module (`export default { en, it, fr }`, keys namespaced `plugin.<id>.<key>`) and calls `addStrings(dicts)` (in `web/lib/i18n.js`) once at module load to merge into the host's shared `DICTS`, then uses the same `t()`/`I18nMixin` as the app (the fragment imports them from the absolute `/lib/i18n.js` — the *same* module instance the host uses, so `t()` and `locale-changed` are shared; no endpoint, no per-locale fetch — all locales ride in the fragment, so a language switch is instant). Mobile-connector is the reference: `common.js` registers the dict + re-exports `t`, and `MobileBase extends I18nMixin(LitElement)`. **Backend-generated strings** (a plugin's HTTP error/response text, notifications) go through `core_api::i18n`: a plugin declares `Plugin::i18n() -> Vec<LocaleBundle>` (mobile-connector loads them from embedded `i18n/{en,it,fr}.json` via `include_str!`), the `PluginManager` merges every plugin's bundles once at boot into an `I18nCatalog` (`skald_core::i18n`) and injects it as `PluginContext.i18n: Arc<dyn I18nApi>`. At request time the handler resolves the caller (`Caller.user_id` from the auth layer) and calls `i18n.for_user(user_id, key, args).await` — which reads `users.locale`, runs it through the same `resolve_locale` chain, and renders `locale → en → key` with `{name}` placeholders. The frontend surfaces these already-translated: `jf()` throws the server's response text verbatim. Front and back keep **separate** tables (UI labels ≠ error strings; overlap is minimal) but share the `plugin.<id>.` namespace convention. The mechanism is general (any plugin, and eventually the core, registers the same way); only mobile-connector uses it so far.
+### dev-docs
 
-**Role-driven interface** (§0.1 — data, not enums): `roles.attrs` JSON may carry `"ui_mode": "simple"`. `/api/auth/me` resolves it via `RoleAttrs` (`admin` is always `full`) and the sidebar renders chat + inbox only for simple-mode members; the role editor exposes it as an "Interface" select. Hiding links is never access control — routes stay capability-gated server-side. `MeResponse` also carries `locale`, `default_locale` and `encrypted`.
+`dev-docs/*.md` carries the **third standing rule**, for the same reason as the other two: **a change to a subsystem updates that subsystem's dev-doc in the same change.** These files are the recorded rationale — what was tried, what broke, why the obvious alternative was rejected — and a rationale reconstructed later is reconstructed from the code, which is the one version that cannot explain itself. New subsystem ⇒ new file plus a row in [`dev-docs/README.md`](dev-docs/README.md) *and* in the routing table at the top of this file; if it does not appear in both, nobody will open it.
 
-**Security-group picker (per-session, runtime, role-gated).** A **security-group** is a *permission bundle only* — a `tool_permission_groups` id, driving tool visibility/approval — **not** a "mode" (no system-context injection; the `RunContext.system_prompt` substrate exists but is unused by the picker). The role carries the user's **allowed set** (default `permission_group` + `attrs.permission_groups`, §0.1); a new non-project session inherits the role's default group (`sessions.rs::create` → `role_default_run_context`). The chat surface switches it **at runtime like the model pill**: `copilot.js` renders a shield pill (hidden when ≤1 group) fed by `GET /api/my/security-groups` (the caller's role set, joined with group names; `admin` → all); selecting one sends the WS control message `{type:"select_security_group", group}` (`chat-session.js::_selectGroup`, twin of `select_client`). The server (`ws.rs::handle_select_security_group_msg`) validates against the role, persists it on `chat_sessions.run_context`, updates the live handler, and **broadcasts `ServerEvent::SecurityGroupSelected`** so every open tab re-syncs (the initial state is sent on WS connect). **Enforcement is server-side** via the shared `run_context::validate_run_context_for_role` (used by both the WS path and the REST `set_session_run_context`): a non-admin may only pick a group in its role's effective set (else 403), and **every other `RunContext` field** (`system_prompt`, `allow_fs_writes`/`allow_fs_reads`, `working_directory`) is **discarded** — closing an fs-escalation hole; `admin` passes through unchanged.
+That rule has a **read half, and it is the half that gets skipped**: you do not edit a subsystem you have not read the dev-doc for — see [How this documentation is organized](#how-this-documentation-is-organized). Writing into a file you opened only at the end is bookkeeping; the file earns its cost only when it is read before the first edit.
 
-**Selection is gated once; the persisted group is re-checked on every load.** `validate_run_context_for_role` runs at *selection* time, and the result is persisted on `chat_sessions.run_context` — so on its own it let a group survive the role that granted it, indefinitely and across restarts (revoke `ops` from a role, and every session that had already picked it kept running on it). The fix is a second, narrower seam: `run_context::reconcile_group_for_user`, run by `ChatSessionManager::get_or_create_handler` on **every** handler build, which treats the stored group as *advisory* and degrades it when the owner's current role no longer allows it. Three properties are load-bearing: (a) it degrades to the **role's default group** (`role_default_group`, the same seam `sessions.rs` uses for a new session, so start-group and fallback-group cannot drift) — **never to `None`**, because a missing group means the catch-all `default`, whose rules are the fallback tier under every other group, so clearing *widens*; (b) it touches **only** `security_group`, unlike the selection path, so a project session's server-built `project_root`/`system_prompt` survive a permissions edit; (c) on uncertainty (unknown user, unreadable role, DB error) it leaves the stored group alone — guessing could only widen. The liveness half is `Skald::revalidate_security_groups_for_{user,role}`, called **synchronously** from the roles API (`update`) and the users API (role reassignment), which reconciles already-open handlers, persists, and emits `SecurityGroupSelected` so the pill re-syncs. Same rule as revocation: authorization is pushed, never left to the bus.
+Keep the split honest in the other direction too: a rule a change *anywhere* could violate belongs in `CLAUDE.md`, not in a dev-doc nobody loaded.
 
-The role editor (`roles-page.js`) sets the default group + an allowed-groups checklist (→ `attrs.permission_groups`) + a **default-assistant** select (→ `attrs.chat_agent`) fed by `GET /api/agents` filtered to `type:chat` minus `project-coordinator` (source-driven); the same exclusion is enforced server-side in the roles API (`validate_chat_agent`).
+### The changelog
+
+`CHANGELOG.md` (repo root) is the release history, and it carries the **twin standing rule**: every change a user or an operator would notice must add a bullet under `## [Unreleased]` **in the same change** — a feature, a behaviour change, a bug fix, a new config key, an image-tag bump. Same reason as `docs/`: written after the fact it is written from the diff, which is exactly the version nobody can use.
+
+Format is [Keep a Changelog](https://keepachangelog.com): newest first, one `## [x.y.z] - YYYY-MM-DD` section per released version, bullets grouped under `Added` / `Changed` / `Fixed` / `Removed` / `Security`. The versions are the **workspace `Cargo.toml` version** — the same string `ci/verify-version.sh` gates a release PR on — so cutting a release is two edits in one commit: bump `version` in `Cargo.toml`, and rename `## [Unreleased]` to the version with today's date, leaving a fresh empty `Unreleased` above it. There are no git tags on this repo; the changelog *is* the record of what a given `v{version}` tarball contains.
+
+Entries are written **for the person reading the release, not for the person who wrote the code**: say what changed for them, not which module moved — the commit message and the diff already hold that. Which is also the test for whether a bullet is owed at all: a refactor with no observable effect gets none, however large. Keep one bullet per user-visible thing, not one per commit, and fold a fix-on-top-of-an-unreleased-feature into that feature's bullet rather than listing a bug that never shipped. History before `0.2.0` is not covered — git is the record for it.

-| `plugin-catalog.js` | `<plugin-catalog>` | `#plugins` — admin status board: one card per plugin (enable toggle + health dot + Configure → `#plugin-detail`) |
-| `plugin-detail.js` | `<plugin-detail>` | `#plugin-detail?id=<id>` — one plugin's admin page: instance-config form (`config_schema`) + a **read-only** roster of who holds it, linking to `#users/{id}` (plugin twin of `connector-detail.js`) |
-| `users-page.js` | `<users-page>` | `#users` list + `#users/{id}` one user's page: Profile, **Connectors**, **Plugins**, Security. Both grant sections are the single write path for "what may this person use" |

-# Skald Connector Authoring Guide
-
-Instructions for generating a **correct connector** for the Skald marketplace
-(`https://connectors.skaldagent.net`). Give this file to the agent that produces
-new connectors.
-
-A connector is a folder served by the marketplace. Skald installs it, verifies
-every file against a SHA-256 pinned in the index, then either runs it on the host
-(global connector) or copies it into the user's container and runs it there
-(per-user connector, blueprint §6/§7).
-
----
-
-## 1. The two documents
-
-### 1a. The root index — `connectors.json`
-
-One array of entries, each pointing at a connector folder. **The index is the
-signable root: it is the only place that lists a connector's files and their
-SHA-256 digests.** Skald refuses any file whose bytes do not match.
-
-```jsonc
-{
-  "version": 1,
-  "connectors": [
-    {
-      "id": "whatsapp",                 // unique slug = folder name

-**Rules**
-
-- `files[].path` is relative to the connector folder. List **every** file the
-  connector ships (server code, `package.json`/`requirements.txt`, icons, and the
-  `connector.json` itself). A missing or mismatched digest fails the install.
-- Compute `sha256` over the exact bytes served: `sha256sum <file>`.
-- Do **not** list `node_modules/` or any generated deps — those are installed on
-  the box, not shipped (see §5).
-- `size` is optional but recommended.

-plain relative filename (`index.js`, `server.py`, `pkg/server.py`).

-## 2. Server contract (MCP over stdio)
-
-A **local** connector is a program speaking JSON-RPC 2.0 over stdin/stdout. It
-MUST handle:
-
-- `initialize` → `{ protocolVersion, capabilities: { tools: {} }, serverInfo }`
-- `notifications/initialized` → no response
-- `tools/list` → `{ tools: [ { name, description, inputSchema } ] }`
-- `tools/call` → `{ content: [ { type: "text", text } ], isError? }`
-
-**stdout is reserved for JSON-RPC only.** Send all logs/diagnostics to **stderr**.
-Anything a library prints to stdout (a logger, a banner) corrupts the protocol —
-silence it (e.g. Baileys/pino → a silent logger; Python → `print(…, file=sys.stderr)`).
-
-A **remote** connector is an HTTP MCP endpoint (`mcp_config.url` +
-`transport: "streamable-http"`); no code runs on the box.
-
-### 2a. Friendly tool names (`tools[]`) — optional
-
-Raw MCP tool names are ugly in the chat UI (`search_files`, `send_message`). The
-optional top-level `tools[]` block gives each one a human title shown as the tool
-card's heading:
-
-```jsonc
-"tools": [
-  { "name": "send_message",   "display_name": "Send Message" },
-  { "name": "list_chats",     "display_name": "List Chats" },
-  { "name": "download_media", "display_name": "Download Media" }
-]
-```
-
-- `name` — the **raw** tool name exactly as your server returns it from `tools/list`.
-- `display_name` — the friendly card title (English only; not internationalized).
-
-**Resolution order** for a tool's card title is **`tools[].display_name` → the MCP
-`title` field → a prettified raw name**. So you have two ways to set a friendly
-name, and can skip `tools[]` entirely:
-
-1. **This block** — the authoritative override, curated in the manifest.
-2. **The MCP `title` field** — if your `tools/list` entries already carry a
-   `title` (MCP 2025-06-18+), Skald uses it automatically; no manifest change
-   needed. `tools[]` wins if both are present.
-3. If neither is set, Skald title-cases the raw name (`send_message` → "Send
-   Message").
-
-**Icons are per connector, not per tool.** Every tool of a connector shows that
-connector's own `icon_small`; there is no per-tool icon field. Only list a tool in
-`tools[]` when its prettified name isn't good enough — partial lists are fine
-(unlisted tools fall through to steps 2–3).
-
----
-
-## 3. Placement & risk vocabulary (what the words mean)
-
-| Manifest | Meaning |
-| --- | --- |
-| `scope: "user"` | runs **once per user**, inside their container. Personal creds. |
-| `scope: "global"` | runs **once for the household**, on the host. Shared, stateless. Admin enables it with a key. |
-| `type: "mcp_local"` | ships code that will **execute on the box** — installing needs the admin `mcp.register_local_script` capability (RCE-bearing act, §14). |
-| `type: "mcp_remote"` | just an HTTP URL; no local code. |
-
-Pick the narrowest: a personal messaging/email/calendar connector is
-`scope: "user"`; a shared search API is `scope: "global"`.
-
----
-
-## 4. Authentication (`auth.type`)
-
-| `auth.type` | Flow | Ships |
-| --- | --- | --- |
-| `none` | nothing to sign in | — |
-| `api_key` | user pastes a key/secret into a form | an `env[]` schema (§4b) |
-| `oauth2` | browser consent → paste code back | `auth.provider` + `auth.scopes` + `auth.deliver` (§4c) |
-| `qr` | server shows a QR, user scans with a phone | a `login_status` tool (§4d) |
-
-### 4b. `api_key` — the `env[]` schema
-
-Each entry drives one form field **and** is injected as an env var / URL token to
-the server:
-
-```jsonc
-"env": [{
-  "name": "tavilyApiKey",
-  "label": "Tavily API key",
-  "description": "Create one at https://app.tavily.com.",
-  "required": true,
-  "secret": true,                       // rendered masked, stored encrypted
-  "example": "tvly-xxxxxxxx"
-}]
-```
-
-The server reads each value from `process.env.<name>` (or `os.environ`). For a
-**remote** connector that wants the key in the URL, use a placeholder:
-`"url": "https://mcp.example.com/?key={SECRET:tavilyApiKey}"`.
-
-### 4c. `oauth2` — provider consent
-
-```jsonc
-"auth": {
-  "type": "oauth2",
-  "provider": "google",                 // slug into the admin's sign-in providers
-  "scopes": ["https://www.googleapis.com/auth/gmail.modify"],
-  "deliver": { "as": "env", "format": "google_authorized_user", "env": "GMAIL_CREDS_JSON" }
-}
-```
-
-The manifest names **only** the provider slug, scopes, and how the obtained token
-is delivered — never client secrets or endpoint URLs (those are admin-entered,
-kept off the public feed). Skald handles PKCE + code exchange and injects the
-credential as the named env var. `format`: `google_authorized_user` (Google) or
-`refresh_token`. Today only `as: "env"` is wired.
-
-### 4d. `qr` / interactive device login — the generic contract
-
-For a connector whose credential is produced by **scanning/pairing** (WhatsApp
-today), there is no code to paste. The rule:
-
-> **Expose one extra tool, `login_status`, returning a JSON object** (as the
-> `text` of a normal text result). Skald calls it directly (never the agent) and a
-> login panel polls it.
-
-```jsonc
-// login_status result text (a JSON string):
-{
-  "state": "connecting" | "need_scan" | "ready" | "logged_out",
-  "qr": "data:image/png;base64,…",   // present ONLY while state == need_scan
-  "message": "human-readable line"
-}
-```
-
-- `activate` on a `qr` connector inserts a **pending** row and **starts the
-  server** (so it can produce the QR), then hands off to the login panel.
-- The panel polls `POST /api/mcp/login/status`; when `state == "ready"` the
-  connector is marked ready and starts automatically on later logins.
-- Also expose a `logout` tool (clears the session, forces a fresh QR) — the panel
-  calls it via `POST /api/mcp/login/reset` to re-link a different phone.
-- The **credential is the on-disk session**, not a token. Persist it **inside the
-  connector's own directory** (e.g. `./auth/` next to the entry file). That folder
-  lives under the bind-mounted home, so it survives container recreates and
-  connector updates. Never store it under a shared/global path.
-
-Skald resolves `auth.type: "qr"` the same way whether it appears in the index
-entry or the manifest.
-
----
-
-## 5. Dependencies (node & python) — how they get installed
-
-**Do not ship `node_modules/` or vendored wheels.** Declare deps as a standard
-manifest **file** and Skald installs them inside the container:
-
-- **node:** ship a `package.json` with a `dependencies` map. Skald runs
-  `npm ci --omit=dev` (falling back to `npm install --omit=dev`) in the connector
-  dir. `node_modules/` resolves automatically beside the entry file.
-- **python:** ship a `requirements.txt`. Skald installs it with
-  `pip install --target .pydeps` and puts `.pydeps` on the server's `PYTHONPATH`.
-
-This runs at activation **and** on every startup, guarded by a **content hash** of
-the connector's source files:
-
-- first activation / a brand-new container → full install,
-- a connector **update** (any shipped file changed) → re-copy + re-install,
-- unchanged → skipped in microseconds.
-
-So you never write install steps into the manifest — just ship the dep file, list
-it in the index with its SHA-256, and set `requires: ["NODE"]` / `["PYTHON"]` as a
-human hint. Pin versions in `package.json` / `requirements.txt` for reproducible
-installs. Keep the dep tree lean (containers are slim; avoid native-heavy
-packages where a pure alternative exists — e.g. Baileys instead of a browser).
-
----
-
-## 6. Verify-before-save (optional but recommended)
-
-Ship a `verify.py` / verify snippet and reference it:
-
-```jsonc
-"verify": { "command": "python3 verify.py", "timeout_secs": 15 }
-```
-
-It runs with the collected env/secret injected and must print **one JSON object**
-on stdout: `{"ok": bool, "message": string, "details"?: object}`, exit 0 on
-success. Used for `api_key`/`none` connectors to test creds before activating.
-(A `qr` connector needs no verify — its `login_status` is the live check.)
-
----
-
-## 7. Versioning & updates
-
-Three fields, in **both** the index entry and the `connector.json`, kept identical:
-
-| field | type | role |
-| --- | --- | --- |
-| `version` | **integer** | monotonic build number, **per connector** — the machine comparison key |
-| `version_string` | string (semver) | display only |
-| `version_release_date` | ISO date `YYYY-MM-DD` | display only |
-
-- `version` is a **number, not a string** (`1`, not `"1"` or `"2.0.1"`). Start at
-  `1` for the first release under this scheme; **`+1` on every change** to any
-  shipped file **or to any manifest metadata** (description, icons, `version_string`).
-  Never reuse or decrement.
-- Skald stores the installed `version` and compares it to the feed's: a strictly
-  greater feed `version` shows **"update available"** in the marketplace, and the
-  Install button becomes **Update**. Clicking it re-downloads the files and rewrites
-  the catalog row.
-- **The integer is the *only* "is there an update?" signal** — it is compared
-  strictly (`feed > installed`). `version_string` (semver), icons and
-  `llm_short_description` are **never** compared, so a change to any of them that
-  does not also bump the integer is **invisible**: no "update available" badge
-  appears. This is the common trap — a "content-only" edit (e.g. a better
-  `llm_short_description`) that forgets the integer.
-- **Two propagation paths, do not conflate them:**
-  - *Per-user code + deps* (the scripts, `package.json`/`requirements.txt`) reconcile
-    on a **content-hash** of the source files (§5), so new code lands at each user's
-    next login even without a reinstall.
-  - *Catalog metadata* (`llm_short_description` → the model's prompt, icons, friendly
-    name) is **not** in that hash — it lives in the catalog row and is rewritten only
-    by an explicit **reinstall/Update**. On reinstall Skald re-pulls the current feed
-    (never the browse cache) and pushes the new description live: enabled global
-    servers restart with it, and every logged-in user who activated the connector has
-    it restarted with the fresh `llm_short_description` — no re-login needed.
-- So: to ship a new `llm_short_description`, **bump the integer** (so the admin sees
-  "update available") and the admin clicks **Update**. Nothing auto-propagates a
-  description change.
-- `version_string` and `version_release_date` are display metadata only — never
-  compared. (Migration note: replace any legacy string `"version": "2.0.1"` with
-  the integer `version` + `version_string`.)
-

-## 8. Checklist for a new connector
-
-1. Folder `myconn/` with: entry file, `connector.json`, deps file
-   (`package.json`/`requirements.txt`), `icon_sm.svg`, `icon_lg.svg`,
-   optional `verify.*`.
-2. Server speaks MCP over stdio (§2); **stdout = JSON-RPC only**.
-3. `mcp_config.args[0]` names the entry file.
-4. Correct `type` + `scope` (§3) and `auth.type` (§4).
-5. For `qr`: implement `login_status` (+ `logout`), persist the session under the
-   connector dir (§4d).
-6. Deps declared as a file, **not** vendored (§5).
-7. Add the entry to `connectors.json` with a correct `sha256` for **every** file.
-8. Bump `version`.

+## Adding a new agent: the skills index is opt-in
+
+An agent sees the installed skills **only** if its `AGENT.md` carries the
+`<!-- SKILLS_LIST -->` placeholder, normally through
+`<!-- INCLUDE: common/skills.md -->`. There is no `meta.json` flag: the sentinel
+*is* the switch, exactly as it is for `<!-- MCP_LIST -->`.
+
+So a new agent starts **without** the index and stays without it until someone
+adds the line. That is the deliberate direction of the default: the opposite one
+— an agent inheriting the index by forgetfulness — is the worse failure, because
+the index is written in the imperative ("you MUST read its SKILL.md") and an
+unattended `type: system` agent has its approvals auto-denied and sometimes no
+tools at all.
+
+`common/skills.md` is **one line and deliberately holds no prose**, unlike
+`common/mcp.md`. Every word — the imperative header, the list, the closing rules
+— is produced by the renderer, so that an instance with no skills installed gets
+an empty string instead of a header promising a list that isn't there. (That is
+not hypothetical: the MCP section keeps its prose in the fragment, and its empty
+state once had the model invent a discovery tool to fill the gap.) The fragment
+cannot explain itself in place either — `resolve_includes` copies any line that
+is not an upper-case sentinel straight into the prompt, so a comment there would
+be read by the model.
+
+The rule of thumb: a `chat` or `task` agent gets the include, a `system` agent
+does not. Put the line **as low as possible** in the prompt (by convention right
+after `common/mcp.md`) — anything above it survives in the provider's cached
+prefix when a skill is added or removed. `crates/skald-core/src/agents.rs` has a
+test that holds every shipped agent to this.

+## Notification preferences
+
+A background agent — **event triage** — reads every event that reaches this user (email, WhatsApp, calendar) and decides what is worth notifying. Its decisions are steered by `user-memory/notifications.md`: **that file is injected into event triage's prompt verbatim**, exactly as written. Event triage never sees this conversation, so this file is the only way the user's wishes reach it.
+
+When the user asks to change what they are notified about ("stop telling me about…", "ping me when…", "mute this chat"), **record it in `user-memory/notifications.md`**, in the user's own language.
+
+A rule is useful to event triage only if it can be matched against an event, so:
+
+- **Pin down the source when it matters.** Event triage sees each event's source (email, WhatsApp, calendar) and fields like sender, subject and chat name. "I don't want notifications from Mario" is ambiguous — Mario *where*? If the user didn't say and the answer changes the rule, ask. Rules about one source go under that source's heading.
+- **Some rules have no source.** "No promotional material" or "anything about the Guatemala trip" apply everywhere — file them under `## General`; no need to ask.
+- **Be as specific as you can.** An email address, a phone number or a chat name beats a first name. If memory holds the identifier (a contact note), use it.
+
+Keep the file in this shape — one rule per bullet, dated, edited in place rather than rewritten:
+
+```md
+# Notification preferences
+
+_Updated: YYYY-MM-DD_
+
+## General
+- No promotional material, except travel offers about Guatemala from "Viaggiare" or "Avventure nel mondo" — YYYY-MM-DD
+
+## Email

+
+## WhatsApp
+- Ignore group chats unless I am mentioned by name — YYYY-MM-DD
+
+## Calendar

+```
+

+- It is a **snapshot of that moment**, not live state. It is not repeated while the

+  sentence" — and only for the thing that request actually names.
+- When the request stands on its own, **ignore the section entirely**: never open,

+## How the user writes
+
+When the user tells you how they want something written — or corrects a draft you produced — treat it as a **durable preference, not a one-off instruction**. Record it under a `## Writing style` section in `user-memory/user.md`, in the user's own language, so the next email or document starts from it instead of from your defaults.
+
+Worth recording:
+
+- **Wording** — terms they use or refuse, spellings, the name they give recurring things
+- **Openings** — how they start an email
+- **Closings** — how they sign off
+- **Formal vs. informal** — what actually changes between the two registers
+- **Per-recipient exceptions** — someone they write to differently from everyone else
+
+Keep the section **short: 10 lines at most**. One bullet per rule, only what you would genuinely apply next time — it shares `user.md`'s line budget, so it is a cheat sheet, not a style guide. Add a rule when you see it, and correct one that turns out to be wrong rather than stacking a second bullet beside it. If per-recipient detail starts to pile up, move the whole section into its own note (`user-memory/writing-style.md`) and leave one pointer line in `user.md`.
+
+```md
+## Writing style
+- Informal email: opens "Hi <name>", closes "Talk soon"
+- Formal email: opens "Dear <title> <surname>", closes "Kind regards"
+- Says "colleagues", never "resources"
+- Writes to the accountant formally, despite being on first-name terms
+```
+
+Before drafting an email or a document, **apply what is there**. If `user.md` is not already in front of you, `read_file` it first.

+//! What the agent is told its sandbox can run — a **discovery aid, not an
+//! inventory**.
+//!
+//! The failure this closes is upstream of any tool call: an agent that does not
+//! know `ffmpeg` is installed either declines the job or spends a round finding
+//! out. So the point is to make the common case answerable without a round-trip,
+//! and nothing more. It follows that:
+//!
+//! - **The list is curated, not discovered.** `ls /usr/bin` is 800 entries of
+//!   coreutils noise; a hint that long is not a hint. [`PROBE_ALLOWLIST`] is the
+//!   curation — the image's own toolbelt plus the handful of things an agent
+//!   plausibly installs — and its **order is meaningful** (grouped by the kind of
+//!   work), which is why nothing here sorts.
+//! - **The probe exists so the list cannot lie**, not so it can discover. A
+//!   hand-maintained list drifts from the image, and a container recreate throws
+//!   away everything an agent installed with apt; `command -v` at login means we
+//!   never announce something that is not there.
+//! - **Incompleteness is stated, not hidden.** The rendered section says the list
+//!   is partial and that more can be installed — so a tool outside the allowlist
+//!   costs the agent one `command -v`, which is what it would have paid anyway.
+//!
+//! Because it is a hint, staleness is cheap in both directions: a mid-session
+//! install is known to the agent that performed it, and a container recreate
+//! costs one `not found` plus an `apt-get install` on a path the agent was
+//! already walking. Hence a plain login-time snapshot, refreshed at the next
+//! login, and no invalidation machinery.

+//! `DocxConverter` — converts word-processor documents (`.docx`, `.doc`,
+//! `.odt`, `.rtf`) to PDF using LibreOffice in headless mode
+//! (`soffice --convert-to pdf`).
+//!
+//! Used by the file viewer (`GET /api/file?…&compile-docx=true`) to render
+//! word documents as PDFs on demand — the word-family twin of
+//! [`crate::latex::LatexCompiler`].
+//!
+//! ## Caching (content-addressed)
+//!
+//! Unlike a `.tex` source, a word document is **self-contained**: images,
+//! styles and fonts travel inside the file itself, so there is no dependency
+//! graph to track and the `.fls`-sidecar machinery of the LaTeX cache would
+//! buy nothing. The cache key is a short SHA-256 of the document bytes: any
+//! edit changes the hash and invalidates naturally, and two paths holding the
+//! same document share one cached PDF.
+//!
+//! One artefact lives under `<tmp>/skald-docx/`:
+//!
+//! | Artefact             | Key                        | Purpose           |
+//! |----------------------|----------------------------|-------------------|
+//! | `<content-hash>.pdf` | SHA-256 of the file bytes  | The converted PDF |
+//!
+//! ## Container-shuttled inputs
+//!
+//! [`DocxConverter::convert_bytes`] exists for documents that live **only
+//! inside a user's container** (`/tmp/…`): the caller pulls the bytes out
+//! (`container::exec_fs::read`) and the converter works on a host-side
+//! scratch copy. This is correct precisely because the format is
+//! self-contained — a bare copy loses nothing. (LaTeX deliberately does not
+//! get this treatment: a shuttled `.tex` would silently lose its relative
+//! `\input` / `\includegraphics` dependencies.)
+//!
+//! ## LibreOffice quirks this lives with
+//!
+//! - `soffice` locks its user-profile directory, so concurrent conversions —
+//!   or a stale lock left by a killed run — make later invocations fail.
+//!   Every conversion therefore gets a **private profile**
+//!   (`-env:UserInstallation`) inside its per-run scratch directory, which is
+//!   removed afterwards.
+//! - A failed conversion does not always exit non-zero: a missing output
+//!   file is treated as a failure too, with the captured output as detail.
+//! - The scratch copy's **name** is how soffice picks its import filter, so
+//!   the shuttled input keeps the caller's extension (`input.docx`,
+//!   `input.odt`, …).
+//!
+//! ## Failure modes
+//! - `ToolMissing` — no LibreOffice on the host (neither `soffice` /
+//!   `libreoffice` on PATH nor the macOS app bundle).
+//! - `Timeout` — conversion exceeded [`CONVERT_TIMEOUT_SECS`].
+//! - `Failed { output }` — non-zero exit or missing output file; carries the
+//!   captured stdout/stderr so the viewer can surface it.
+//! - `Io` — underlying I/O error (reading the source, writing the cache…).
