+# Bootstrap Wizard
+
+Interactive, AI-guided setup for Turnstone deployments. Instead of manually
+editing `.env` files and reading deployment docs, the wizard walks you through
+every decision conversationally and generates all the config files for you.
+
+## Quick Start
+
+```bash
+turnstone-bootstrap
+```
+
+That's it — no flags, no arguments. The wizard prompts for everything.
+
+## How It Works
+
+1. **Pick a model** — Choose OpenAI, Anthropic, or a local/vLLM endpoint to
+   power the wizard. Local endpoints auto-detect available models.
+2. **Answer questions** — The AI walks you through deployment mode, LLM
+   provider, database, authentication, ports, and optional features.
+3. **Review generated files** — Each file is previewed before writing. You
+   confirm or reject every write.
+4. **Start the stack** — The wizard prints the exact `docker compose` command
+   and a `setup.sh` script to create your first admin user, roles, and policies.
+
+## What Gets Generated
+
+| File | Purpose |
+|------|---------|
+| `.env` | All environment variables for `compose.yaml` |
+| `setup.sh` | Post-start script: creates admin user, roles, tool policies, prompt templates via the API |
+| `docker-compose.override.yaml` | Only if customizations beyond env vars are needed |
+
+## Requirements
+
+- **Python 3.11+** with turnstone installed (`pip install turnstone`)
+- **An LLM API key** — for the wizard itself (OpenAI, Anthropic, or a local
+  model). This can differ from the LLM your deployment will use.
+- **Docker & Docker Compose** — needed to run the stack. The wizard detects
+  whether Docker is installed and gives platform-specific install instructions
+  if it's missing. You can still generate config files without Docker.
+
+## Deployment Modes
+
+The wizard supports two deployment modes:
+
+- **Single-node production** (`docker compose --profile production up`) —
+  1 server + bridge + console + PostgreSQL + Redis. Good for most use cases.
+- **Multi-node cluster** (`docker compose --profile cluster up`) —
+  10-node server/bridge fleet + PostgreSQL + Redis. For high-throughput or
+  HA deployments.
+
+## Example Session
+
+```
+$ turnstone-bootstrap

+ Found model: Qwen/Qwen3-32B
+
+ Connected to Qwen/Qwen3-32B. Handing off to AI assistant...
+
+> (AI walks you through the rest interactively)
+```
+
+## Tips
+
+- **Re-run safely** — running the wizard again detects your existing `.env`
+  and offers to update it rather than overwriting.
+- **Duplicate writes are skipped** — if the LLM tries to write the same file
+  twice with identical content, it's silently ignored.
+- **Type `quit` to exit** at any time during the conversation.
+- **Ctrl+C** is handled gracefully — press once to interrupt, twice to exit.

+### Governance
+
+Turnstone includes a built-in governance layer for enterprise deployments — manage who can do what, which tools run unattended, and where every token goes.
+
+- **RBAC** — 15 granular permissions, 3 built-in roles (admin / operator / viewer), custom roles, privilege escalation prevention
+- **Tool policies** — glob-pattern rules (`allow` / `deny` / `ask`) with priority ordering; automate approvals or lock down dangerous tools
+- **Prompt templates** — reusable system messages with `{{variable}}` substitution and categories
+- **Usage tracking** — per-request token and tool metrics, aggregation by day / model / user, automatic 90-day pruning
+- **Audit logging** — append-only event trail for all admin mutations, IP-aware, 365-day retention
+
+All governance features are managed through the console admin panel (10 tabs) and the full REST API. See [docs/governance.md](docs/governance.md) for setup and configuration.
+
+### Intent Validation (LLM Judge)
+
+Every tool call that requires human approval is evaluated by an intent validation judge that provides a structured risk assessment alongside the approval prompt — so instead of "approve this bash command?", users see a verdict with risk level, confidence, recommendation, and reasoning.
+
+The system uses a two-tier evaluation pipeline:
+
+1. **Heuristic tier** (instant, free) — 23 pattern-based rules classify tool calls by severity. Catches destructive commands (`rm -rf /`, `DROP TABLE`), privilege escalation (`sudo`), credential access, and more. Results appear immediately.
+2. **LLM judge tier** (async) — A full LLM evaluation runs in the background with access to `read_file` and `list_directory` for evidence gathering. The judge can inspect files that a write would overwrite, check directory contents before a delete, and cite specific evidence in its reasoning. Results update the UI progressively when ready.
+
+The judge defaults to the same model as the session (self-consistency) but can be configured to use a separate model — useful when running a small local model for tasks but wanting a commercial model for safety evaluation.
+
+```toml
+[judge]
+enabled = true           # on by default
+model = ""               # empty = same as session model
+provider = ""            # empty = same as session provider
+timeout = 60.0           # generous for local models
+```
+
+Verdicts are persisted for audit and exposed via Prometheus metrics (`turnstone_judge_verdicts_total`, `turnstone_judge_llm_latency_seconds`). See [docs/judge.md](docs/judge.md) for the full guide.

+When the total tool count exceeds a configurable threshold (default 20), MCP tools are automatically deferred using native `defer_loading` on Anthropic and OpenAI APIs, or a transparent client-side BM25 search for local models.

-Turnstone supports the [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) for connecting external tool servers.

+## Authentication
+
+When auth is enabled (`[auth].enabled = true` or `TURNSTONE_AUTH_ENABLED=1`), all API endpoints except public paths require a valid token.
+
+### Sending Credentials
+
+Include a token in one of two ways:
+
+- **Bearer header**: `Authorization: Bearer <token>`
+- **Cookie**: `turnstone_auth=<token>` (set automatically by the login endpoint)
+
+The server accepts three token types:
+
+| Type | Format | Example |
+|------|--------|---------|
+| JWT | Base64 segments separated by dots | `eyJhbG...` |
+| API token | `ts_` prefix + 64 hex chars | `ts_a1b2c3d4...` |
+| Config token | Arbitrary string from `config.toml` | `my-secret-token` |
+
+JWTs are the recommended credential for browser sessions. API tokens are suitable for programmatic access and CI/CD. Config tokens are a simple option for single-node deployments.
+
+### `POST /v1/api/auth/login`
+
+Authenticate with credentials and receive a JWT. Accepts two credential formats:
+
+**Username + password:**
+
+```json
+{"username": "alice", "password": "hunter2"}
+```
+
+**API token:**
+
+```json
+{"token": "ts_a1b2c3d4e5f6..."}
+```
+
+**Response (success):** `200`
+
+```json
+{
+  "status": "ok",
+  "role": "full",
+  "scopes": "approve,read,write",
+  "jwt": "eyJhbGciOiJIUzI1NiIs...",
+  "user_id": "u_abc123"
+}
+```
+
+The response also sets a `turnstone_auth` HttpOnly cookie containing the JWT.
+
+**Response (failure):** `401`
+
+```json
+{"error": "Invalid credentials"}
+```
+
+---
+
+### `POST /v1/api/auth/logout`
+
+Clears the `turnstone_auth` cookie. No request body required.
+
+**Response:** `200`
+
+```json
+{"status": "ok"}
+```
+
+The response includes a `Set-Cookie` header that expires the auth cookie.
+
+---
+
+### `GET /v1/api/auth/status`
+
+Returns the current authentication state. Works with or without a valid token.
+
+**Response (authenticated):** `200`
+
+```json
+{
+  "authenticated": true,
+  "user_id": "u_abc123",
+  "scopes": ["approve", "read", "write"],
+  "source": "jwt"
+}
+```
+
+**Response (not authenticated):** `200`
+
+```json
+{
+  "authenticated": false,
+  "user_id": null,
+  "scopes": [],
+  "source": null
+}
+```
+
+**Response (auth disabled):** `200`
+
+```json
+{
+  "authenticated": false,
+  "auth_enabled": false
+}
+```
+
+---
+
+### `POST /v1/api/auth/setup`
+
+Creates the first admin user when no users exist in the database. This is a
+public endpoint (no authentication required) that only succeeds when auth is
+enabled and the user database is empty. Both the server and console expose
+this endpoint.
+
+**Request body:**
+
+```json
+{
+  "username": "admin",
+  "display_name": "Admin",
+  "password": "strongpass"
+}
+```
+
+| Field          | Type   | Required | Validation                  |
+|----------------|--------|----------|-----------------------------|
+| `username`     | string | yes      | 1-64 ASCII characters       |
+| `display_name` | string | yes      | Non-empty                   |
+| `password`     | string | yes      | Minimum 8 characters        |
+
+**Response (success):** `200`
+
+```json
+{
+  "status": "ok",
+  "user_id": "u_abc123",
+  "username": "admin",
+  "role": "full",
+  "scopes": "approve,read,write",
+  "jwt": "eyJhbGciOiJIUzI1NiIs..."
+}
+```
+
+The response also sets a `turnstone_auth` HttpOnly cookie containing the JWT.
+
+**Response (already set up):** `409`
+
+```json
+{"error": "Setup already completed"}
+```
+
+Returned when one or more users already exist in the database.
+
+**Response (auth disabled):** `400`
+
+```json
+{"error": "Auth is not enabled"}

+## User Identity and Authentication
+
+Turnstone supports three authentication mechanisms, unified behind an
+`AuthResult` dataclass that carries `user_id`, `scopes`, and `token_source`:
+
+1. **Config-file tokens** — static secrets in `config.toml` `[[auth.tokens]]`
+   or the `TURNSTONE_AUTH_TOKEN` env var. Validated in-memory via
+   `hmac.compare_digest`. Map to scopes through their role (`read` or `full`).
+2. **API tokens** — database-backed, prefixed `ts_`, stored as SHA-256 hashes
+   in the `api_tokens` table. Can be exchanged for JWTs via
+   `POST /v1/api/auth/login`.
+3. **JWTs** — short-lived HMAC-SHA256 session tokens (default 24h) issued after
+   successful credential validation. Contain `sub` (user_id), `scopes`, and
+   `src` (origin) in claims.
+
+### Scope Model
+
+Three hierarchical scopes control endpoint access:
+
+| Scope | Grants | Endpoints |
+|-------|--------|-----------|
+| `read` | SSE streams, workstream listing, history | GET endpoints |
+| `write` | `read` + send, command, workstream create/close | POST to `/api/send`, `/api/command`, etc. |
+| `approve` | `write` + tool approval, admin operations | POST to `/api/approve`, `/api/admin/*` |
+
+### Middleware Flow
+
+`AuthMiddleware` (ASGI) intercepts every request:
+
+1. **Public path check** — `/`, `/static/*`, `/shared/*`, `/health`,
+   `/metrics`, `/openapi.json`, `/docs`, `/api/auth/*`, and `/api/auth/setup`
+   are always allowed.
+2. **Token extraction** — `Authorization: Bearer <token>` header first, then
+   `turnstone_auth` cookie as fallback.
+3. **Token type detection** — dots in the token indicate JWT; `ts_` prefix
+   indicates API token; otherwise config-file token.
+4. **Validation** — JWT signature check, API token hash lookup in storage, or
+   config-token hmac comparison.
+5. **Scope check** — `required_scope(method, path)` determines the minimum
+   scope; the request is rejected with 403 if the token lacks it.
+6. **Context propagation** — on success, `ctx_user_id` is set so structured
+   logging includes the authenticated identity on every log event.
+
+### Architecture Split
+
+- **Console** is the auth management hub — it hosts the admin endpoints for
+  creating users, issuing API tokens, and managing channel mappings. User
+  records and token hashes live in the shared storage backend. The console
+  dashboard includes an **admin panel** (Users and Tokens tabs) for managing
+  credentials through the browser.
+- **Server** is a JWT validator only — it validates tokens on each request but
+  never creates users or tokens. Both processes share the same `jwt_secret`
+  (via `TURNSTONE_JWT_SECRET` env var or `[auth].jwt_secret` config).
+- **First-time setup** — both server and console expose
+  `POST /v1/api/auth/setup`, a public endpoint that creates the initial admin
+  user when no users exist. This avoids the chicken-and-egg problem of needing
+  `approve` scope to create the first user via `/api/admin/users`.
+
+### Auth Storage Tables
+
+Three tables in `storage/_schema.py` support identity:
+
+```sql
+users
+  user_id        TEXT PRIMARY KEY
+  username       TEXT NOT NULL UNIQUE
+  display_name   TEXT NOT NULL
+  password_hash  TEXT NOT NULL       -- bcrypt
+  created        TEXT NOT NULL
+
+api_tokens
+  token_id       TEXT PRIMARY KEY
+  token_hash     TEXT NOT NULL UNIQUE  -- SHA-256 of raw token
+  token_prefix   TEXT NOT NULL         -- first 8 chars for display

+  name           TEXT NOT NULL         -- human-readable label
+  scopes         TEXT NOT NULL         -- comma-separated
+  created        TEXT NOT NULL
+  expires        TEXT                  -- optional expiry timestamp
+
+channel_users
+  channel_type      TEXT NOT NULL      -- e.g. "slack", "discord"
+  channel_user_id   TEXT NOT NULL      -- platform-specific user ID
+  user_id           TEXT NOT NULL      -- FK to users
+  PRIMARY KEY (channel_type, channel_user_id)

+lifecycle, password hashing, and deployment hardening.

+## Channel Integrations
+
+> See also: [Channel Integrations guide](channels.md)
+
+The `turnstone-channel` gateway bridges external messaging platforms
+(Discord, Slack, Teams) to the turnstone cluster via Redis MQ. Each
+platform adapter implements the `ChannelAdapter` protocol and translates
+between platform-native events and turnstone MQ messages.
+
+The `ChannelRouter` manages bidirectional routing: it maps platform
+channel/thread IDs to turnstone workstream IDs, handles workstream
+creation and stale-route recovery, and resolves platform users to
+turnstone identities via the `channel_users` table. When an evicted
+workstream is reactivated, the router uses atomic resume via the
+`resume_ws` field on `CreateWorkstreamMessage` — the server resumes
+the old workstream's conversation during creation in a single HTTP
+request, eliminating ordering fragility. The bridge emits a
+`WorkstreamResumedEvent` to confirm success.
+
+Discord ships as the first adapter. See [channels.md](channels.md) for
+setup instructions, configuration reference, and the adapter development
+guide.
+
+### Notification Subsystem
+
+The `notify` tool enables the LLM to send notifications to users or
+channels without going through MQ. The server calls the channel gateway
+directly over HTTP for lower latency: `_exec_notify()` queries the
+`services` database table for healthy channel gateways (heartbeat within
+120 seconds), authenticates with a service JWT (`aud: turnstone-channel`),
+and POSTs to `POST /v1/api/notify` on the first healthy gateway. The
+gateway validates the JWT, resolves the target (username lookup via
+`channel_users` or direct `channel_type`+`channel_id`), and delegates to
+the appropriate `ChannelAdapter.send()`. Delivery retries up to 3 times
+with backoff, re-querying the service registry on each attempt. See
+[Notification Flow diagram](diagrams/png/17-notify-flow.png).
+
+---
+
+## Governance
+
+> See also: [Governance documentation](governance.md) | [Governance Architecture diagram](diagrams/19-governance-architecture.puml)
+
+Turnstone governance extends the Phase 1 auth system with role-based access
+control (RBAC), tool execution policies, prompt templates, usage tracking,
+and audit logging. The permission model has two layers: legacy scopes
+(`read`, `write`, `approve`) checked by `AuthMiddleware`, and 15 granular
+permissions checked per-endpoint by `require_permission()`. Three built-in
+roles (admin, operator, viewer) are seeded by migration 008; custom roles
+can be created with any permission subset. JWTs carry both `scopes` and
+`permissions` claims for backward compatibility.
+
+Tool policies use glob pattern matching (`fnmatch`) with priority-ordered
+first-match-wins evaluation to control tool execution (allow/deny/ask).
+Prompt templates provide reusable system messages with `{{variable}}`
+substitution. Usage events are recorded per-LLM-request for token
+accounting. An append-only audit log captures all admin mutations.
+
+Workstream templates build on top of prompt templates as complete behavioral
+profiles applied at workstream creation. While prompt templates inject system
+message text, workstream templates define model, temperature, reasoning effort,
+max tokens, auto-approve policy, token budget, and agent max turns. Templates
+are snapshot-applied once at creation — not a live binding. The
+`workstream_templates` table (migration 011) supports auto-versioning, and
+workstreams record which template and version spawned them. Token budget
+enforcement tracks consumption in `session.send()` with 80% warning and
+100% approval gate via the `__budget_override__` synthetic tool name.
+
+The console admin panel adds 6 governance tabs (Roles, Policies, Templates,
+WS Templates, Usage, Audit) for a total of 11 tabs, all permission-gated.
+Both Python and TypeScript SDKs expose governance methods on the console
+client.
+
+## Intent Validation
+
+> See also: [Intent Validation guide](judge.md) | [Judge Architecture diagram](diagrams/png/22-judge-architecture.png)
+
+Intent validation provides advisory risk assessments for tool calls that
+require human approval. The system runs a two-tier evaluation pipeline
+implemented in `turnstone/core/judge.py`:
+
+1. **Heuristic tier** (synchronous, sub-millisecond) -- A priority-ordered
+   rule table using fnmatch tool patterns and regex argument patterns. Four
+   severity levels: critical (deny), high (review), medium (review), low
+   (approve). First match wins. The heuristic verdict is attached to the
+   `approve_request` SSE event immediately.
+
+2. **LLM judge tier** (asynchronous, daemon thread) -- A multi-turn evaluation
+   where the judge LLM receives conversation context and tool call details,
+   optionally uses `read_file`/`list_directory` to gather evidence (with
+   security-hardened path blocking), and produces a structured JSON verdict.
+   If the LLM verdict has higher confidence than the heuristic, it replaces
+   it via an `intent_verdict` SSE event.
+
+The judge is session-scoped (`IntentJudge`), lazy-initialized on first
+approval, and configured via the `[judge]` config section or `--judge` CLI
+flags. By default it uses self-consistency (same model), but supports
+cross-model and cross-provider configurations. Sub-agents (plan, task)
+are exempt. All verdicts are persisted to the `intent_verdicts` table
+(migration 012) with the user's final decision, enabling future calibration.
+The console exposes `GET /v1/api/admin/verdicts` for audit queries
+(requires `admin.judge` permission).

+
+The `turnstone-channel` gateway connects external messaging platforms to
+turnstone workstreams via Redis MQ. Each platform adapter translates
+platform-native events (messages, button clicks, slash commands) into
+turnstone MQ messages, and renders workstream output back into the
+platform's UI.
+
+Discord ships as the first adapter. The adapter protocol is designed for
+future Slack and Teams integrations.
+

+- **ChannelRouter** (`turnstone/channels/_routing.py`) — maps

+  creation via MQ, stale route detection, and user identity resolution.
+- **AsyncRedisBroker** (`turnstone/mq/async_broker.py`) — async Redis
+  client compatible with discord.py's event loop. Used by the router for
+  pub/sub and queue operations.
+- **channel_users table** — maps `(channel_type, channel_user_id)` to a
+  turnstone `user_id`. Messages from unlinked users are silently dropped.
+- **channel_routes table** — persistent channel-to-workstream mappings.
+  Survives bot restarts. Stale routes (evicted workstreams) are detected

+
+---
+
+## Discord Setup
+
+### 1. Create a Discord Application
+
+1. Go to https://discord.com/developers/applications
+2. Click **New Application** and give it a name
+3. Navigate to the **Bot** tab and click **Reset Token** to generate a
+   bot token. Copy it immediately — it is shown only once.
+4. On the same **Bot** tab, scroll down to **Privileged Gateway Intents**
+   and enable **MESSAGE CONTENT INTENT**
+5. Navigate to **OAuth2 > URL Generator**
+6. Under **Scopes**, check `bot` and `applications.commands`
+7. Under **Bot Permissions**, check:
+   - View Channels
+   - Send Messages
+   - Send Messages in Threads
+   - Create Public Threads
+   - Read Message History
+   - Add Reactions
+   - Embed Links
+8. Copy the generated URL, open it in a browser, and add the bot to your
+   Discord server
+
+### 2. Configure Turnstone
+
+**Environment variables** (recommended for Docker):
+
+```bash
+TURNSTONE_DISCORD_TOKEN=your-bot-token-here
+TURNSTONE_DISCORD_GUILD=123456789  # optional, restrict to one guild
+```
+
+**CLI flags** (bare-metal):
+
+```bash
+turnstone-channel \
+  --discord-token "your-bot-token" \
+  --discord-guild 123456789 \
+  --redis-host localhost \
+  --redis-port 6379
+```
+
+**Docker Compose** (production profile):
+
+```bash
+# In .env file:
+TURNSTONE_DISCORD_TOKEN=your-bot-token
+TURNSTONE_DISCORD_GUILD=123456789
+```
+
+Then start the stack:
+
+```bash
+docker compose --profile production up
+```
+
+The `channel` service starts automatically when
+`TURNSTONE_DISCORD_TOKEN` is set.
+
+### 3. Link User Accounts
+
+Discord users must link their account to a turnstone user before they can
+interact with the bot. Unlinked users' messages are silently ignored.
+
+1. The user must have a turnstone API token — created via the admin panel
+   or `turnstone-admin create-token`
+2. In Discord, the user runs `/link`. A modal appears prompting for the
+   API token (the token is never visible in Discord audit logs because it
+   is submitted via modal, not as a slash command argument).
+3. The token is validated against the database. If valid, a
+   `channel_users` mapping is created.
+4. The user can now @mention the bot or use slash commands.
+
+An admin can also force-link or unlink users via the console admin panel
+(Admin > Channels tab).
+
+---
+
+## Usage
+
+### Conversations
+
+- **@mention** the bot in any allowed channel to start a new conversation.
+  The bot creates a Discord thread from the message and a turnstone
+  workstream behind it.
+- All subsequent messages in the thread are routed to the same workstream.
+- The bot streams responses via message edits, updated approximately every
+  1.5 seconds.
+- If the workstream is evicted for capacity, the next message in the
+  thread auto-creates a new workstream and atomically resumes the
+  previous workstream via the `resume_ws` field on
+  `CreateWorkstreamMessage`. The server resumes the workstream during
+  creation (same HTTP request), and the bridge emits a
+  `WorkstreamResumedEvent` back to the channel. The thread receives a
+  *"Resumed: {name} ({count} messages restored)"* confirmation.
+
+### Slash Commands
+
+| Command | Description |
+|---------|-------------|
+| `/link` | Link Discord account to turnstone (opens modal for API token) |
+| `/unlink` | Unlink Discord account |
+| `/ask <message>` | Create a new thread and workstream with an initial message |
+| `/status` | Show workstream info for the current thread (ephemeral) |
+| `/close` | Close the workstream, delete the route, and archive the thread |
+
+### Tool Approvals
+
+When manual approval is enabled (the default), tool calls are displayed as
+an orange embed with:
+
+- Tool name and argument preview
+- **Approve** (green), **Reject** (red), **Always Approve** (gray) buttons
+- Only linked users can interact with approval buttons
+- The approval decision is forwarded through MQ to the bridge, which
+  relays it to the server
+
+Buttons use static `custom_id` values so they survive bot restarts.
+Correlation data (`ws_id`, `correlation_id`) is stored in the embed footer.
+
+**Auto-approval:** When `auto_approve` is true (via `--auto-approve`), or when
+all tools in the request match the `auto_approve_tools` list in the adapter
+config, the bot auto-responds with approval and posts a
+"*Tool auto-approved.*" notice to the thread instead of showing buttons. The
+`auto_approve_tools` list is set via the `ChannelConfig.auto_approve_tools`
+field (useful for allowing specific tools like `bash` or `read_file` while
+still requiring manual approval for others).
+
+### Plan Reviews
+
+Plan review requests are displayed as a blue embed with:
+
+- **Approve Plan** (green) button — approves the plan with empty feedback
+- **Request Changes** (gray) button — opens a modal for feedback text
+  (up to 2000 characters)
+- Feedback is forwarded through MQ as a `PlanFeedbackMessage`

+## User Identity
+
+- The `channel_users` table maps `(channel_type, channel_user_id)` to a
+  turnstone `user_id`
+- Self-service linking via the `/link` slash command (modal input, not
+  visible in Discord audit logs)
+- Admin can force-link or unlink via the console admin panel (Admin >
+  Channels tab). Unlinking uses a styled confirmation modal.
+- Unlinked users' messages are silently dropped
+- A user can be linked across multiple platforms (e.g. Discord + Slack)
+
+See [Security: Database Schema](security.md#database-schema) for the
+`channel_users` table definition.
+
+---
+
+## Workstream Lifecycle
+
+1. **Creation** — @mention or `/ask` creates a Discord thread and a
+   turnstone workstream. The `ChannelRouter` persists the mapping in the
+   `channel_routes` table.
+2. **Active** — messages are routed bidirectionally. The bot streams
+   responses via message edits (updated every ~1.5 seconds).
+3. **Eviction** — the server evicts an idle workstream for capacity. The
+   route is preserved and the thread stays open.
+4. **Reactivation** — the next message in the thread detects the stale
+   route (no MQ owner) and creates a new workstream with the old `ws_id`
+   as `resume_ws` on the `CreateWorkstreamMessage`. The server resumes
+   the workstream during creation (no separate command or reverse lookup
+   needed). The bridge emits a `WorkstreamResumedEvent` to the channel, and
+   the thread displays *"Resumed: {name} ({count} messages restored)"*.
+   If the old workstream was pruned, a fresh one starts with no error.
+5. **Close** — `/close` command closes the workstream via MQ, deletes the
+   route, unsubscribes from events, and archives the Discord thread.
+
+---
+
+## Notifications
+
+> See also: [Notification Flow diagram](diagrams/png/17-notify-flow.png)
+
+The `notify` tool allows the LLM to proactively send notifications to
+users or channels on external platforms. This is useful for alerting
+people about task completion, errors, or important updates without
+waiting for them to check in.
+
+### Targeting
+
+Two modes:
+
+- **Username** — provide a turnstone `username`. The gateway resolves
+  it via the `channel_users` table and sends to all linked channels
+  (e.g. Discord + future Slack).
+- **Direct** — provide `channel_type` + `channel_id` to target a
+  specific platform channel or user DM.
+
+### Delivery Flow
+
+Notifications bypass MQ for lower latency. The server calls the channel
+gateway directly over HTTP:
+
+1. The LLM calls the `notify` tool with a message and target
+2. `_exec_notify()` queries the `services` table for healthy channel
+   gateways (heartbeat within the last 120 seconds)
+3. The server mints a service JWT (`aud: turnstone-channel`) via
+   `ServiceTokenManager` and POSTs to the first healthy gateway
+4. The gateway validates the JWT, resolves the target, and calls
+   `adapter.send()` on the appropriate platform adapter
+5. On failure, the server tries the next gateway. If all fail, it
+   retries up to 2 more times (delays: 1s, 3s), re-querying the
+   service registry on each attempt
+
+### Service Registry
+
+The channel gateway registers itself in the `services` database table
+on startup and sends a heartbeat every 30 seconds. On shutdown it
+deregisters. Services are considered stale after 120 seconds (4 missed
+heartbeats) and are excluded from `list_services()` queries.
+
+The `services` table schema:
+
+| Column | Description |
+|--------|-------------|
+| `service_type` | Service category (e.g. `"channel"`) |
+| `service_id` | Unique instance ID (`channel-<hostname>-<random>`) |
+| `url` | HTTP base URL for the service |
+| `last_heartbeat` | ISO 8601 timestamp of last heartbeat |
+| `created` | ISO 8601 timestamp of initial registration |
+
+### Security
+
+- **Authentication** — the gateway's `POST /v1/api/notify` endpoint
+  requires authentication. Configure either `TURNSTONE_JWT_SECRET`
+  (the server mints JWTs with `aud: turnstone-channel` automatically)
+  or a static token via `--auth-token`. If neither is set, the
+  gateway fails closed and rejects all requests with 401. Server JWTs
+  (`aud: turnstone-server`) are rejected.
+- **Rate limit** — maximum 5 notifications per turn. The counter only
+  increments on successful delivery, so failures don't consume the
+  budget.
+- **SSRF protection** — only `http://` and `https://` service URLs
+  are allowed. Other schemes are silently skipped.
+- **Mention sanitization** — `discord.utils.escape_mentions()` is
+  applied before sending, preventing `@everyone` / `@here` abuse.
+- **Error redaction** — generic error messages are returned to the
+  LLM. Internal details (service IDs, URLs, exception messages) are
+  logged server-side only.
+
+---
+
+## Adding New Adapters
+
+The `ChannelAdapter` protocol defines the interface any platform adapter
+must implement:
+
+```python
+class ChannelAdapter(Protocol):
+    channel_type: str
+
+    async def start(self) -> None: ...
+    async def stop(self) -> None: ...
+    async def send(self, channel_id: str, content: str) -> str: ...
+    async def edit_message(self, channel_id: str, message_id: str, content: str) -> None: ...
+    async def send_approval_request(self, channel_id: str, ws_id: str, correlation_id: str, items: list[dict]) -> None: ...
+    async def send_plan_review(self, channel_id: str, ws_id: str, correlation_id: str, content: str) -> None: ...
+    async def create_thread(self, parent_channel_id: str, name: str, message_id: str = "") -> str: ...
+```
+
+To add a new platform:
+
+1. Create `turnstone/channels/<platform>/` package
+2. Implement the `ChannelAdapter` protocol
+3. Add a `--<platform>-token` flag and detection logic in
+   `turnstone/channels/cli.py`
+4. Add the optional dependency in `pyproject.toml` (e.g.
+   `turnstone[slack]`)
+
+See `turnstone/channels/discord/` as a reference implementation.

 ### SSE Proxy
 
-SSE streams (`/v1/api/events`, `/v1/api/events/global`) are proxied by creating a per-connection `httpx.AsyncClient(timeout=None)`, streaming the upstream response via `aiter_text()`, parsing SSE framing (`\n\n` delimiters), and re-emitting events through `EventSourceResponse`. Each proxied SSE stream requires its own httpx client since the shared client's 30-second timeout would kill long-lived connections.
+SSE streams (`/v1/api/events`, `/v1/api/events/global`) are proxied as raw byte passthrough — the console opens an `httpx.AsyncClient.stream()` to the upstream server (with `read=None` and `pool=None` timeouts since SSE connections are long-lived) and relays every byte via `StreamingResponse`. This preserves server-side ping comments, event framing, and keepalives verbatim without parsing or re-encoding.
 
 ### Authentication
 
-The proxy forwards requests to server nodes using the console's `--auth-token`. The console's own auth middleware also checks proxy routes — `POST` requests to proxy write endpoints (`/v1/api/send`, `/v1/api/approve`, etc.) require the `"full"` auth role, preventing read-only tokens from escalating to write operations.
+The proxy forwards the user's JWT to upstream server nodes — it extracts the token from the incoming request's cookie (or `Authorization` header) and adds it as a `Bearer` header on the proxied request.  Since all services share the same `TURNSTONE_JWT_SECRET`, the user's JWT is valid on every node without re-authentication.  The console's own auth middleware also checks proxy routes — `POST` requests to proxy write endpoints (`/v1/api/send`, `/v1/api/approve`, etc.) require `write` scope, preventing read-only tokens from escalating via proxy.  The static `--auth-token` / `proxy_auth_token` is used as a fallback when no user JWT is present.

+
+## Scheduled Tasks
+
+The console includes a background **TaskScheduler** daemon that creates workstreams on a timed basis via the MQ broker. It supports cron-based recurring schedules and one-shot `at` schedules.
+
+### Architecture
+
+The scheduler runs as a daemon thread inside the console process. Every `check_interval` seconds (default 15) it:
+
+1. Acquires a distributed lock via Redis `SET NX EX` (prevents duplicate dispatch in multi-console deployments)
+2. Queries the storage backend for tasks whose `next_run <= now` and `enabled = true`
+3. Dispatches each due task as one or more `CreateWorkstreamMessage` via MQ
+4. Updates `last_run` and computes the next `next_run` (or disables one-shot `at` tasks)
+5. Releases the lock via Lua script (safe conditional delete)
+
+Run history is automatically pruned (runs older than 90 days) approximately once per hour.
+
+### Schedule Types
+
+| Type | Field | Behavior |
+|------|-------|----------|
+| `cron` | `cron_expr` | Recurring schedule using standard 5-field cron syntax. Requires `croniter`. |
+| `at` | `at_time` | One-shot: fires once at the given ISO 8601 timestamp (must include timezone), then auto-disables. |
+
+### Target Modes
+
+| Mode | Behavior |
+|------|----------|
+| `auto` | Picks the reachable node with the most available capacity |
+| `pool` | Pushes to the shared inbound queue (any bridge picks it up) |
+| `all` | Fan-out to all reachable nodes (capped at `max_fan_out`, default 20) |
+| `<node_id>` | Targets a specific node by ID |
+
+### Configuration
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `check_interval` | `15.0` | Seconds between scheduler ticks |
+| `lock_ttl` | `60` | Distributed lock TTL in seconds |
+| `max_fan_out` | `20` | Maximum nodes for `all` target mode |
+
+Dependency: `croniter` (installed with turnstone).
+

+  3. Initial workstream: session.set_watch_runner(runner)
+  4. _lifespan(): runner.start() — daemon thread begins
+
+  **New workstream:**
+  session.set_watch_runner(runner) in create_workstream()
+  → registers dispatch_fn for ws_id
+
+  **Eviction / close:**
+  session.close() → runner.remove_dispatch_fn(ws_id)
+  Watches remain active in DB — WatchRunner uses restore_fn
+
+  **Restart recovery:**
+  Overdue watches fire ONE immediate poll
+  next_poll updated to now + interval
+  Normal cadence resumes
+
+  **Shutdown:**
+  _lifespan(): runner.stop() — joins thread

+# Governance
+
+Turnstone governance provides role-based access control (RBAC), tool execution
+policies, prompt templates, usage tracking, and audit logging for the admin
+console.
+
+## Architecture
+
+See [diagram: 19-governance-architecture.puml](diagrams/19-governance-architecture.puml).
+
+### RBAC (Roles & Permissions)
+
+The permission model has two layers:
+
+1. **Scopes** (legacy) — `read`, `write`, `approve`. Checked by `AuthMiddleware`
+   on every request based on URL path classification.
+2. **Permissions** (granular) — 15 permission strings checked per-endpoint by
+   `require_permission()`.
+
+**Built-in roles** (seeded by migration 008):
+
+| Role | Permissions |
+|------|-------------|
+| admin | read, write, approve, admin.users, admin.roles, admin.orgs, admin.policies, admin.templates, admin.audit, admin.usage, admin.schedules, admin.watches, tools.approve, workstreams.create, workstreams.close |
+| operator | read, write, workstreams.create, workstreams.close |
+| viewer | read |
+
+Custom roles can be created with any subset of the 15 valid permissions.
+
+**Auth flow:**
+1. User logs in (password or API token) → `_load_user_permissions()` aggregates
+   permissions from all assigned roles
+2. `_permissions_to_scopes()` derives legacy scopes (any `admin.*` → `approve`)
+3. JWT created with both `scopes` and `permissions` claims
+4. Middleware checks scope → handler checks permission via `require_permission()`
+
+### Tool Policies
+
+Admin-defined rules that control tool execution:
+
+- **Pattern matching**: Glob syntax via `fnmatch` (e.g., `bash*`, `file_write`, `*`)
+- **Actions**: `allow` (auto-approve), `deny` (block), `ask` (normal approval flow)
+- **Priority**: Higher priority evaluated first, first match wins
+- **Enforcement**: `evaluate_tool_policies_batch()` called in `WebUI.approve_tools()`
+  before the `auto_approve` check
+- **MCP granular policies**: MCP resources and prompts are evaluated using their
+  `approval_label` for fine-grained control:
+  - Resource reads: `mcp_resource__{uri}` (e.g., `mcp_resource__file:///docs/*` to allow,
+    `mcp_resource__*` to deny all)
+  - Prompt invocations: `mcp__{server}__{prompt}` (e.g., `mcp__trusted__*` to allow,
+    `mcp__*` to require approval for all)
+  - Built-in tools continue to use `func_name` for backward compatibility
+
+### Prompt Templates
+
+Admin-curated system message templates injected at workstream startup:
+
+- **Runtime behavior**: Templates are loaded once at session creation and injected
+  into the system message *before* user `instructions`. Templates set the baseline;
+  instructions customize per-workstream behavior.
+- **Default templates**: All `is_default=true` templates auto-apply to new
+  workstreams, concatenated in alphabetical order by name. Use name prefixes
+  (e.g. `01-safety`, `02-style`) to control ordering.
+- **Explicit selection**: `--template <name>` CLI flag, `template` field on
+  `POST /v1/api/workstreams/new`, console creation modal dropdown, scheduled task
+  config, and channel adapter config. An explicit template *replaces* defaults.
+- **Variables**: Three built-in placeholders resolved at load time:
+  `{{model}}` (active model name), `{{ws_id}}` (workstream ID),
+  `{{node_id}}` (server node ID). Unrecognized placeholders are kept as-is.
+- **Runtime switching**: `/template <name>` to switch, `/template clear` to revert
+  to defaults, `/template` to show current. Persisted across resume.
+- **Categories**: general, engineering, support, custom, mcp
+- **Content limit**: 32 KB per template (enforced on create/update)
+- **Storage**: `prompt_templates` table with JSON `variables` array. Migration 010
+  adds `template` column to `scheduled_tasks`.
+- **MCP sync**: MCP server prompts auto-sync into prompt_templates with
+  `origin="mcp"`, `mcp_server` set, and `readonly=True`. Manual templates take
+  precedence on name collision. MCP-synced content updates reset `is_default` to
+  prevent compromised servers from injecting defaults. Admin UI shows origin badge
+  and disables edit/delete for MCP-sourced templates.
+
+### Workstream Templates
+
+Workstream templates are behavioral profiles applied at workstream creation — the next level beyond prompt templates. While prompt templates inject system message text, workstream templates define the complete workstream configuration.
+
+**What they define:**
+- System prompt (inline text OR reference to a prompt template by name)
+- Model override (empty = server default)
+- Temperature, reasoning effort, max tokens, agent max turns
+- Auto-approve policy (blanket and/or per-tool list)
+- Token budget (0 = unlimited; warns at 80%, requires approval at 100%)
+- Completion notification config (stored for v2 dispatch)
+
+**Storage:** `workstream_templates` table (migration 011) with auto-versioning. Edits snapshot the pre-update state into `workstream_template_versions`. Workstreams record which template and version spawned them via `ws_template_id` + `ws_template_version` columns.
+
+**Applied once at creation:** Template settings are snapshot-applied to the workstream's config. Not a live binding — template updates don't affect running workstreams.
+
+**Prompt template drift detection:** When a workstream template references a prompt template, a SHA-256 hash of the prompt content is stored at ws_template create/update time. At workstream creation, the server compares the stored hash against current content and logs a warning on mismatch.
+
+**Admin API:** 7 endpoints under `/v1/api/admin/ws-templates` (list, create, get, update, delete, version history) plus a read-only summary at `/v1/api/ws-templates`. Permission: `admin.ws_templates`.
+
+**Console UI:** "WS Templates" tab (11th admin tab) with CRUD table, create/edit modals (name, description, system prompt source toggle, model, auto-approve, per-tool auto-approve, temperature, reasoning effort, max tokens, agent max turns, token budget, enabled), and version history modal. "Profile" dropdown on workstream creation modal. "WS Template" dropdown on scheduler create/edit modals.
+
+**Token budget enforcement:** Tracked in `session.send()`. At 80% consumption, emits an info message. At 100%, the next turn requires explicit approval via the `__budget_override__` synthetic tool name (reuses existing approval UI — inline in browser, Discord buttons, bridge auto-approve). The synthetic name can be targeted by tool policies (e.g. `__budget_override__` → `allow` for admins).
+
+**SDK:** Python (`list_ws_templates`, `create_ws_template`, `get_ws_template`, `update_ws_template`, `delete_ws_template`, `list_ws_template_versions`) and TypeScript (`listWsTemplates`, `createWsTemplate`, etc.) on both sync and async console clients. `ws_template` parameter on `create_workstream()` for both server and console SDKs.
+
+### Usage Tracking
+
+Per-LLM-request token and tool call metrics:
+
+- **Recording**: `on_status()` in `WebUI` records a `usage_event` after each
+  LLM response with prompt/completion tokens, tool call count, model, ws_id
+- **Querying**: `GET /v1/api/admin/usage` with `group_by` (day/hour/model/user)
+  and time range filtering
+- **Pruning**: `prune_usage_events(retention_days=90)` and
+  `prune_audit_events(retention_days=365)` run automatically via the
+  console scheduler's periodic cleanup cycle
+
+### Audit Logging
+
+Append-only trail of admin actions:
+
+- **Recording**: `record_audit()` helper called from all admin mutation handlers
+- **Events captured**: user.create, user.delete, token.create, token.revoke,
+  channel.link, channel.unlink, role.create, role.update, role.delete,
+  role.assign, role.unassign, policy.create, policy.update, policy.delete,
+  template.create, template.update, template.delete,
+  ws_template.create, ws_template.update, ws_template.delete, org.update
+- **Querying**: `GET /v1/api/admin/audit` with action/user/time filters + pagination
+
+## Database Schema
+
+Migration 008 adds 7 tables:
+
+| Table | Purpose |
+|-------|---------|
+| `orgs` | Organizations (single default org for now) |
+| `roles` | Named permission bundles (3 builtin + custom) |
+| `user_roles` | User-to-role assignments (composite PK) |
+| `tool_policies` | Per-tool approve/deny/ask rules |
+| `prompt_templates` | Reusable system message templates |
+| `usage_events` | Per-request token/tool metrics |
+| `audit_events` | Admin action log |
+
+Also adds `org_id` column to `users` table.
+
+## API Endpoints
+
+All under `/v1/api/admin/` (requires `approve` scope + granular permission).
+
+| Group | Endpoints | Permission |
+|-------|-----------|------------|
+| Users / Tokens / Channels | 9 (CRUD) | `admin.users` |
+| Roles | 7 (CRUD + assignment) | `admin.roles` / `admin.users` |
+| Orgs | 3 (list, get, update) | `admin.orgs` |
+| Tool Policies | 4 (CRUD) | `admin.policies` |
+| Prompt Templates | 4 (CRUD) | `admin.templates` |
+| Schedules | 6 (CRUD + runs) | `admin.schedules` |
+| WS Templates | 7 (CRUD + versions + summary) | `admin.ws_templates` |
+| Watches | 3 (list, create, cancel) | `admin.watches` |
+| Usage | 1 (aggregated query) | `admin.usage` |
+| Audit | 1 (paginated, filtered) | `admin.audit` |
+
+Full OpenAPI spec at `/openapi.json` and Swagger UI at `/docs`.
+
+## Admin Console UI
+
+6 new tabs added to the admin panel (11 total):
+
+- **Roles** — CRUD roles, permission checkbox grid, user role assignment modal
+- **Policies** — CRUD tool policies with colored action badges (green/red/amber)
+- **Templates** — CRUD prompt templates with wide modal, textarea editor
+- **WS Templates** — CRUD workstream templates with create/edit modals, version history
+- **Usage** — Summary readouts + CSS bar chart, time range + group-by selectors
+- **Audit** — Filterable log with relative timestamps, load-more pagination
+
+Tabs are permission-gated: hidden if the user lacks the required permission.
+
+## SDK
+
+Both Python and TypeScript console SDKs expose governance methods:
+
+**Python** (`TurnstoneConsole` / `AsyncTurnstoneConsole`):
+- `list_roles()`, `create_role()`, `update_role()`, `delete_role()`
+- `list_user_roles()`, `assign_role()`, `unassign_role()`
+- `list_orgs()`, `get_org()`, `update_org()`
+- `list_policies()`, `create_policy()`, `update_policy()`, `delete_policy()`
+- `list_templates()`, `create_template()`, `update_template()`, `delete_template()`
+- `list_ws_templates()`, `create_ws_template()`, `get_ws_template()`, `update_ws_template()`, `delete_ws_template()`, `list_ws_template_versions()`

+
+**TypeScript** (`TurnstoneConsole`):
+- Same methods with camelCase naming and typed interfaces
+
+## Security Considerations
+
+- **Privilege escalation prevented**: `admin_assign_role` blocks self-assignment
+  and requires caller to hold a superset of the target role's permissions
+- **Permission validation**: Role create/update validates permissions against
+  a 15-item allowlist (`_VALID_PERMISSIONS`)
+- **Self-deletion blocked**: `admin_delete_user` rejects attempts to delete
+  your own account (matching the self-assignment guard on role endpoints)
+- **Field allowlists**: Storage `update_*` methods filter fields against
+  allowlists (`_ROLE_MUTABLE`, `_POLICY_MUTABLE`, etc.) — handler bugs
+  cannot overwrite `role_id`, `builtin`, `created`, or other protected columns
+- **Bootstrap safety**: `handle_auth_setup` fails and rolls back if admin role
+  assignment fails, preventing locked-out first user
+- **API token RBAC**: `_authenticate_api_token` loads permissions from user's
+  roles, ensuring API tokens are subject to RBAC enforcement
+- **Policy evaluation is fail-open**: If storage is unavailable, tool policies
+  degrade to the existing approval flow (not auto-approve)
+- **Audit IP resolution**: `_audit_context()` prefers `X-Forwarded-For` for
+  client IP when behind a reverse proxy, falling back to `request.client.host`

+# Intent Validation (Judge)
+
+> See also: [Judge Architecture diagram](diagrams/png/22-judge-architecture.png)
+
+Intent validation provides advisory risk assessments for tool calls that require
+human approval. An LLM judge evaluates each tool call and presents a structured
+verdict alongside the approval prompt, helping users make informed decisions.
+
+## Overview
+
+When a tool call requires approval, the intent validation system runs a two-tier
+evaluation:
+
+1. **Heuristic tier** (instant) -- Pattern-based risk classification using a
+   rule table. Zero cost, sub-millisecond latency.
+2. **LLM judge tier** (async) -- Semantic evaluation using an LLM with
+   read-only tool access. Runs on a daemon thread and delivers its verdict
+   progressively.
+
+The verdict is purely advisory -- the user always makes the final decision.
+
+The heuristic verdict is attached to the `approve_request` SSE event immediately.
+The LLM verdict arrives later via an `intent_verdict` SSE event, allowing the
+UI to show a spinner that resolves into a richer assessment. Both verdicts are
+persisted to the `intent_verdicts` table for audit and future calibration.
+
+---
+
+## Configuration
+
+### config.toml
+
+```toml
+[judge]
+enabled = true
+model = ""                    # empty = same as session model
+provider = ""                 # empty = same as session provider
+base_url = ""
+api_key = ""
+confidence_threshold = 0.7   # reserved for v2 smart approvals (not used in v1)
+max_context_ratio = 0.5       # max % of judge context window for history
+timeout = 60.0                # seconds (generous for local models)
+read_only_tools = true        # judge can use read_file/list_directory
+```
+
+All fields are optional. The judge is enabled by default; use `enabled = false`
+(or `--no-judge` on the command line) to disable it.
+
+### CLI flags
+
+```
+--judge / --no-judge           Enable/disable (default: enabled)
+--judge-model MODEL            Model for judge
+--judge-provider PROVIDER      Provider for judge
+--judge-timeout SECONDS        LLM judge timeout (default: 60)
+--judge-confidence FLOAT       Confidence threshold (default: 0.7)
+```
+
+CLI flags override `config.toml` values.
+
+---
+
+## Judge Model Selection
+
+- **Default (self-consistency)**: When `model` is empty, the session model
+  evaluates its own tool calls. Research shows self-consistency achieves
+  comparable accuracy to multi-agent debate at a fraction of the cost.
+- **Cross-model**: Use a different model for the judge (e.g. local model for
+  the session, commercial model for the judge). Set `model` and `provider`
+  in the `[judge]` config section, or use `--judge-model` / `--judge-provider`
+  CLI flags.
+- **Cross-provider**: When both `model` and `provider` are set, the judge
+  creates its own LLM client. You can optionally specify `base_url` and
+  `api_key` for non-default endpoints.
+
+---
+
+## Heuristic Rules
+
+The heuristic tier scans a priority-ordered rule table (critical first, low
+last) and returns the first matching rule. Each rule has:
+
+- **Tool pattern**: fnmatch glob matched against `func_name` and `approval_label`
+- **Argument patterns**: Regex patterns matched against the tool's primary
+  argument text (command string for bash, path for file tools, JSON for others)
+- **Risk level, confidence, and recommendation**: Pre-assigned per rule
+
+### Rule tiers
+
+| Tier     | Confidence | Recommendation | Examples |
+|----------|-----------|----------------|----------|
+| Critical | 0.90      | deny           | `rm -rf /`, `mkfs`, `dd if=`, pipe-to-shell, chmod 777 on root, write/edit to `/etc/`, `.ssh/` |
+| High     | 0.80      | review         | `sudo`, `kill -9`, destructive git (`reset --hard`, `push --force`, `clean -f`), DROP TABLE, write/edit secrets (`.env`, `.pem`, `.key`), HTTP mutations, `ssh`/`scp` |
+| Medium   | 0.70      | review         | Package installs (`pip`, `npm`, `apt`, `brew`, `cargo`), `write_file` (default), MCP tool calls, Docker operations |
+| Low      | 0.85      | approve        | `read_file`, `list_directory`, `search`, `recall`, `man`, `use_prompt`, read-only bash commands (`ls`, `cat`, `head`, `grep`, `find`, etc.) |
+
+When no rule matches, the heuristic returns a default verdict: medium risk,
+0.50 confidence, "review" recommendation.
+
+The bash "read-only" rule handles simple pipelines and command chains by
+splitting on `|`, `&&`, `||`, and `;`, then checking each segment individually.
+
+---
+
+## LLM Judge
+
+The LLM judge runs on a daemon thread and performs a multi-turn evaluation:
+
+1. **Context preparation**: Recent conversation history is FIFO-truncated to
+   fit within `max_context_ratio` of the judge's context window. The tool call
+   details (name, approval label, full arguments) are appended as a user message.
+2. **Multi-turn loop** (up to 5 turns): The judge can use `read_file` and
+   `list_directory` to gather evidence before rendering its verdict. Each tool
+   result is appended to the conversation and the judge is called again. On
+   the final turn, tools are stripped and a forcing message instructs the
+   judge to render its verdict immediately.
+3. **Verdict parsing**: The judge's final text response is parsed as JSON using
+   a four-stage strategy: direct parse, markdown code block extraction,
+   brace-counting, and regex field extraction as a last resort.
+4. **Arbitration**: If the LLM verdict has higher confidence than the heuristic,
+   it replaces the heuristic via the `intent_verdict` SSE event.
+
+### Read-only tools
+
+When `read_only_tools` is enabled (default), the judge can use two tools:
+
+- **`read_file`**: Read file contents (capped at 32 KB)
+- **`list_directory`**: List directory entries (capped at 200 entries)
+
+Security hardening blocks access to sensitive paths:
+
+| Category | Blocked patterns |
+|----------|-----------------|
+| System directories | `/etc/`, `/root/`, `/proc/`, `/sys/`, `/dev/` |
+| Credential directories | `.ssh`, `.gnupg`, `.aws`, `.config` |
+| Key files | `*.pem`, `*.key`, `*.p12`, `*.pfx` |
+
+### Timeout
+
+The `timeout` setting (default 60 seconds) is a total budget across all judge
+turns. Time is decremented after each LLM call. If the budget expires mid-turn,
+the judge attempts to parse whatever partial response is available.
+
+---
+
+## Verdict Structure
+
+Each verdict (heuristic or LLM) is an `IntentVerdict` with these fields:
+
+| Field            | Type       | Description |
+|------------------|------------|-------------|
+| `verdict_id`     | string     | Unique identifier (UUID prefix) |
+| `call_id`        | string     | Correlates with the tool call's `call_id` |
+| `func_name`      | string     | Tool function name |
+| `intent_summary` | string     | One-sentence description of what the tool call does |
+| `risk_level`     | string     | `"low"`, `"medium"`, `"high"`, or `"critical"` |
+| `confidence`     | float      | 0.0--1.0, how certain the assessment is |
+| `recommendation` | string     | `"approve"`, `"review"`, or `"deny"` |
+| `reasoning`      | string     | Explanation of the assessment |
+| `evidence`       | list[str]  | Supporting evidence (rule name or file excerpts) |
+| `tier`           | string     | `"heuristic"` or `"llm"` |
+| `judge_model`    | string     | Model used (empty for heuristic tier) |
+| `latency_ms`     | int        | Evaluation time in milliseconds |
+
+---
+
+## Session Integration
+
+The judge is lazy-initialized on first use. When `ChatSession` prepares tool
+calls for approval, it calls `_evaluate_intent()` which:
+
+1. Instantiates `IntentJudge` if not already created
+2. Extracts `func_name`, `func_args`, and `approval_label` from each pending item
+3. Calls `judge.evaluate()` which returns heuristic verdicts immediately
+4. Attaches each heuristic verdict to its item as `_heuristic_verdict`
+5. The daemon thread runs the LLM judge and delivers results via `ui.on_intent_verdict()`
+
+Sub-agents (plan agent, task agent) are exempt from intent validation -- they
+always get full tool visibility without judge evaluation.
+
+---
+
+## Storage and Audit
+
+All verdicts are persisted to the `intent_verdicts` table (migration 012):
+
+- Heuristic verdicts are stored when the `approve_request` event is emitted
+- LLM verdicts are stored when the `intent_verdict` event is delivered
+- The `user_decision` column is updated when the user approves or denies
+
+The console admin panel exposes verdict history via:
+
+```
+GET /v1/api/admin/verdicts?ws_id=&since=&until=&risk_level=&limit=100&offset=0
+```
+
+This endpoint requires the `admin.judge` permission.
+
+---
+
+## SSE Events
+
+### `approve_request` (extended)
+
+When the judge is active, `approve_request` items include a `verdict` field
+with the heuristic verdict, and the event includes a `judge_pending` flag
+indicating that an LLM verdict is in flight:
+
+```json
+{
+  "type": "approve_request",
+  "judge_pending": true,
+  "items": [
+    {
+      "call_id": "call_abc123",
+      "header": "bash: npm install express",
+      "preview": "",
+      "func_name": "bash",
+      "approval_label": "bash",
+      "needs_approval": true,
+      "error": null,
+      "verdict": {
+        "verdict_id": "a1b2c3d4e5f6",
+        "call_id": "call_abc123",
+        "func_name": "bash",
+        "intent_summary": "Package installation: npm install express",
+        "risk_level": "medium",
+        "confidence": 0.70,
+        "recommendation": "review",
+        "reasoning": "Command installs a software package which may modify the environment.",
+        "evidence": ["Matched rule: package-install"],
+        "tier": "heuristic",
+        "judge_model": "",
+        "latency_ms": 0
+      }
+    }
+  ]
+}
+```
+
+### `intent_verdict`
+
+Delivered asynchronously when the LLM judge completes. The UI replaces the
+heuristic verdict badge with the LLM verdict:
+
+```json
+{
+  "type": "intent_verdict",
+  "verdict_id": "f7e8d9c0b1a2",
+  "call_id": "call_abc123",
+  "func_name": "bash",
+  "intent_summary": "Install Express.js web framework via npm",
+  "risk_level": "medium",
+  "confidence": 0.85,
+  "recommendation": "review",
+  "reasoning": "The command installs express from npm. This is a well-known package but will modify node_modules and package.json.",
+  "evidence": ["Checked package.json — express is not currently a dependency"],
+  "tier": "llm",
+  "judge_model": "gpt-5",
+  "latency_ms": 2340
+}
+```
+
+---
+
+## v2 Calibration Path
+
+Run v1 with all tools requiring manual approval to build a local verdict
+dataset. The `intent_verdicts` table accumulates `(tool_call, verdict,
+user_decision)` triples over time. In v2, calibration tooling will analyze
+this dataset to:
+
+- Identify tools that are always approved (candidates for auto-approve policies)
+- Detect false positives in heuristic rules
+- Measure LLM judge accuracy against human decisions
+- Recommend policy changes to reduce approval fatigue
+
+This data-driven approach means v1 is both useful on its own and a foundation
+for automated policy tuning.

 The Python SDK reuses Pydantic models from `turnstone/api/` directly — no schema duplication. The TypeScript SDK has hand-written interfaces matching those models.

+
+## Authentication
+
+When auth is enabled on the server, the SDK handles JWT-based authentication automatically.
+
+### Login Flow
+
+There are two ways to authenticate:
+
+1. **Username + password** — calls `POST /v1/api/auth/login` with credentials. The server validates against the user database and returns a JWT.
+
+2. **API token** — calls `POST /v1/api/auth/login` with a `ts_`-prefixed token string. The server looks up the token, resolves the associated user, and returns a JWT.
+
+In both cases the server returns the JWT in the response body and as a `Set-Cookie` header. The SDK extracts the JWT and includes it as a `Bearer` token in the `Authorization` header on all subsequent requests.
+
+```python
+# Username + password
+client.login(username="alice", password="s3cret")
+
+# API token (created via admin API or turnstone-admin CLI)
+client.login(token="ts_abc123...")
+```
+
+### Token Lifecycle
+
+- JWTs have a configurable expiry (default: 24 hours).
+- `client.auth_status()` returns the current user identity and scopes without refreshing the token.
+- `client.logout()` clears the stored JWT from the client.
+- If a request returns 401, the SDK raises `TurnstoneAPIError` — the caller is responsible for re-authenticating.
+
+### Backward Compatibility
+
+The config-file token (`TURNSTONE_AUTH_TOKEN`) still works as a simple Bearer token for environments that do not use the user/JWT system. When the server receives a non-JWT Bearer token, it falls back to the legacy token check.

+# Security and Authentication
+
+Turnstone uses a layered authentication system with three token types,
+hierarchical scopes, and a split architecture where the console manages
+credentials while individual server nodes validate JWTs locally.
+
+---
+
+## Token Types
+
+### Config-file tokens
+
+Static tokens defined in `config.toml` or the `TURNSTONE_AUTH_TOKEN`
+environment variable. Validated in-memory using `hmac.compare_digest`
+(timing-safe). Each token maps to a role that determines its scopes.
+
+```toml
+[[auth.tokens]]
+value = "tok_legacy"
+role = "full"     # full → {read, write, approve}
+```
+
+Role mappings: `"read"` → `{read}`, `"full"` → `{read, write, approve}`.
+
+Config tokens are sent directly as `Authorization: Bearer tok_legacy`
+on every request. No JWT exchange is needed.
+
+### API tokens
+
+Database-backed tokens prefixed with `ts_`. Created via the admin CLI
+(`turnstone-admin create-token`) or the console admin API. Stored as
+SHA-256 hashes — the raw token is shown exactly once at creation and
+never persisted in plaintext.
+
+```
+$ turnstone-admin create-token --user abc123 --scopes read,write --name "CI bot"
+Token created: ts_a1b2c3d4e5f6...
+(save this — it will not be shown again)
+```
+
+API tokens can be used directly as `Bearer ts_xxx` headers or exchanged
+for a JWT via the login endpoint.
+
+### JWTs
+
+Short-lived session tokens (24 hours by default). Issued after
+authenticating with username/password or by exchanging an API token.
+HS256-signed with a shared secret. Validated locally on every service
+node — no database call per request.
+
+Claims:
+
+| Claim | Description |
+|-------|-------------|
+| `sub` | User ID |
+| `scopes` | Comma-separated scope list (`read,write,approve`) |
+| `src` | Token source (`password`, `api_token`, `config`) |
+| `iss` | Issuer — always `turnstone` |
+| `aud` | Audience — `turnstone-server` or `turnstone-console` |
+| `iat` | Issued-at timestamp |
+| `exp` | Expiry timestamp |
+
+The `aud` claim prevents cross-service token reuse — a JWT issued for the
+console cannot be used to authenticate against a server node, and vice versa.
+Tokens without an `aud` claim are accepted during the rollout window when
+`audience` validation is not specified.
+
+---
+
+## Scope Model
+
+Scopes are hierarchical — higher scopes imply all lower ones.
+
+| Scope | Grants | Implies |
+|-------|--------|---------|
+| `read` | View workstreams, saved workstreams, history | — |
+| `write` | Send messages, create/close workstreams | `read` |
+| `approve` | Approve tool calls, admin endpoints | `read`, `write` |
+
+### Path-to-scope mapping
+
+| Method | Path pattern | Required scope |
+|--------|-------------|----------------|
+| GET | Any protected path | `read` |
+| POST | `/api/send`, `/api/plan`, `/api/command` | `write` |
+| POST | `/api/workstreams/new`, `/api/workstreams/close` | `write` |
+| POST | `/api/cluster/workstreams/new` | `write` |
+| POST | `/api/approve` | `approve` |
+| Any | `/api/admin/*` | `approve` |
+
+Public paths bypass authentication entirely: `/`, `/health`, `/metrics`,
+`/static/*`, `/shared/*`, `/docs`, `/openapi.json`, `/api/auth/login`,
+`/api/auth/logout`, `/api/auth/status`, `/api/auth/setup`.
+
+### RBAC (Granular Permissions)
+
+> See also: [Governance documentation](governance.md)
+
+Scopes provide coarse endpoint-level access control. For finer-grained
+enforcement, the governance layer adds 15 named permissions checked
+per-endpoint by `require_permission()`. Permissions are bundled into
+roles; users are assigned roles via the `user_roles` join table.
+
+At login, `_load_user_permissions()` aggregates all permissions from
+the user's assigned roles. `_permissions_to_scopes()` derives legacy
+scopes for backward compatibility (e.g., any `admin.*` permission
+implies the `approve` scope). The JWT carries both `scopes` and
+`permissions` claims.
+
+Three built-in roles are seeded by migration 008:
+
+| Role | Permissions |
+|------|-------------|
+| admin | All 15 permissions |
+| operator | read, write, workstreams.create, workstreams.close |
+| viewer | read |
+
+Custom roles can be created with any subset of the valid permissions.
+Role creation and update validate permissions against a static allowlist.
+Self-assignment is blocked, and assigning a role requires the caller to
+hold a superset of the target role's permissions.
+
+---
+
+## Login Flows
+
+### Username and password
+
+```
+POST /v1/api/auth/login
+Content-Type: application/json
+
+{"username": "admin", "password": "s3cret"}
+```
+
+Returns a JWT in the response body and sets an `HttpOnly` session cookie.
+
+### API token exchange
+
+```
+POST /v1/api/auth/login
+Content-Type: application/json
+
+{"token": "ts_a1b2c3d4e5f6..."}
+```
+
+The API token is hashed, looked up in the database, and exchanged for a
+JWT with the token's scopes. This is the recommended flow for SDKs and
+automated clients that need cookie-based sessions.
+
+### Config-file tokens (direct)
+
+Config tokens are validated per-request via `hmac.compare_digest`. No
+login exchange is needed — include the token as a `Bearer` header:
+
+```
+Authorization: Bearer tok_legacy
+```
+
+### First-time setup
+
+When no users exist in the database:
+
+1. `GET /v1/api/auth/status` returns `{"setup_required": true}`
+2. The UI presents a setup wizard
+3. `POST /v1/api/auth/setup` creates the first admin user and returns a
+   JWT in one atomic step (no auth required — this is a public endpoint)
+4. The endpoint returns `409 Conflict` if setup has already been completed
+   (i.e. users already exist in the database)
+5. Subsequent admin requests require `approve` scope
+
+The `/api/auth/setup` endpoint is available on both the server and
+console. It validates input before creating the user:
+
+- **username**: 1-64 ASCII characters
+- **display_name**: required (non-empty)
+- **password**: minimum 8 characters
+
+```
+POST /v1/api/auth/setup
+Content-Type: application/json
+
+{"username": "admin", "display_name": "Admin", "password": "strongpass"}
+```
+
+Response:
+
+```json
+{
+  "status": "ok",
+  "user_id": "u_abc123",
+  "username": "admin",
+  "role": "full",
+  "scopes": "approve,read,write",
+  "jwt": "eyJhbGciOiJIUzI1NiIs..."
+}
+```
+
+The response also sets an `HttpOnly` session cookie containing the JWT,
+so the browser is immediately authenticated after setup completes.
+
+---
+
+## Token Detection Order
+
+The auth middleware inspects the `Authorization: Bearer <token>` header
+and classifies the token:
+
+1. **Contains `.`** → JWT → validate HS256 signature and expiry
+2. **Starts with `ts_`** → API token → SHA-256 hash, database lookup
+3. **Otherwise** → config-file token → `hmac.compare_digest` against
+   each configured token
+
+If a session cookie is present and no `Authorization` header is sent,
+the cookie value is treated as a JWT (step 1).
+
+---
+
+## Password Storage
+
+Passwords are hashed with **bcrypt** using a random salt per password.
+Plaintext passwords are only accepted over HTTPS in production
+deployments.
+
+---
+
+## Cookie Security
+
+| Attribute | Value | Purpose |
+|-----------|-------|---------|
+| `HttpOnly` | `true` | Prevents JavaScript access |
+| `SameSite` | `Lax` | CSRF protection |
+| `Path` | `/` | Available to all routes |
+| `Max-Age` | 24 hours | Matches JWT expiry |
+| `Secure` | `true` (default) | Always set unless explicitly disabled for dev |
+
+---
+
+## JWT Configuration
+
+| Setting | Config key | Env var | Default |
+|---------|-----------|---------|---------|
+| Signing secret | `[auth] jwt_secret` | `TURNSTONE_JWT_SECRET` | Auto-generated ephemeral (warning logged) |
+| Expiry | `[auth] jwt_expiry_hours` | — | 24 hours |
+| Algorithm | — | — | HS256 (not configurable) |
+| Minimum secret length | — | — | 32 characters (warning if shorter) |
+
+All service nodes that need to validate JWTs must share the same signing
+secret. If no secret is configured, an ephemeral key is generated at
+startup and a warning is logged — JWTs will not survive restarts or work
+across nodes.
+
+The bridge and console **require** `TURNSTONE_JWT_SECRET` when no
+`--auth-token` is provided. They exit with an error if the secret is
+missing, since ephemeral secrets would silently break inter-service
+communication.
+
+---
+
+## Admin API Endpoints
+
+All admin endpoints require `approve` scope.
+
+### Users
+
+| Method | Path | Description |
+|--------|------|-------------|
+| POST | `/v1/api/admin/users` | Create user (username, display_name, password) |
+| GET | `/v1/api/admin/users` | List all users |
+| DELETE | `/v1/api/admin/users/{user_id}` | Delete user and cascade tokens |
+
+### API tokens
+
+| Method | Path | Description |
+|--------|------|-------------|
+| POST | `/v1/api/admin/users/{user_id}/tokens` | Create API token (returns raw value once) |
+| GET | `/v1/api/admin/users/{user_id}/tokens` | List tokens (prefix only, no hashes) |
+| DELETE | `/v1/api/admin/tokens/{token_id}` | Revoke token |
+
+---
+
+## CLI Administration
+
+The `turnstone-admin` command provides offline user and token management:
+
+```
+turnstone-admin create-user --username admin --name "Admin" [--password] [--token]
+turnstone-admin create-token --user <user_id> --scopes read,write --name "CI bot"
+turnstone-admin list-users
+turnstone-admin list-tokens
+turnstone-admin revoke-token <token_id>
+```
+
+When `--password` is omitted, the CLI prompts interactively. When
+`--token` is passed to `create-user`, an API token is created alongside
+the user and printed to stdout.
+
+---
+
+## Database Schema
+
+```sql
+CREATE TABLE users (
+    user_id    TEXT PRIMARY KEY,
+    username   TEXT NOT NULL UNIQUE,
+    display_name TEXT NOT NULL,
+    password_hash TEXT NOT NULL,
+    created    TEXT NOT NULL
+);
+
+CREATE TABLE api_tokens (
+    token_id     TEXT PRIMARY KEY,
+    token_hash   TEXT NOT NULL,       -- SHA-256 of raw token
+    token_prefix TEXT NOT NULL,       -- first 8 chars for display
+    user_id      TEXT NOT NULL REFERENCES users(user_id),
+    name         TEXT NOT NULL,
+    scopes       TEXT NOT NULL,       -- comma-separated
+    created      TEXT NOT NULL,
+    expires      TEXT                 -- nullable, ISO 8601
+);
+
+CREATE UNIQUE INDEX ix_api_tokens_hash ON api_tokens(token_hash);
+
+CREATE TABLE channel_users (
+    channel_type    TEXT NOT NULL,
+    channel_user_id TEXT NOT NULL,
+    user_id         TEXT NOT NULL REFERENCES users(user_id),
+    created         TEXT NOT NULL,
+    PRIMARY KEY (channel_type, channel_user_id)
+);
+```
+
+The `sessions` and `workstreams` tables have a nullable `user_id`
+column for attribution when auth is enabled.
+
+---
+
+## Revocation
+
+- **API tokens**: Deleting a token via the admin API or CLI prevents new
+  JWTs from being issued with that token. Existing JWTs derived from the
+  token remain valid until they expire (at most 24 hours).
+- **Config-file tokens**: Remove the token from `config.toml` and
+  restart the service. No JWTs are involved, so revocation is immediate.
+- **JWTs**: Cannot be individually revoked. Rely on short expiry (24h)
+  and revoke the underlying credential to prevent renewal.
+
+---
+
+## Architecture
+
+```
+Console (cluster-wide)              Server (per-node)
+┌──────────────────────┐           ┌──────────────────────┐
+│ User/Token CRUD (DB) │           │ JWT validation only  │
+│ Login: creds → JWT   │           │ (shared signing key) │
+│ Admin API endpoints  │           │ Config tokens: hmac  │
+│ Storage: users,      │           │ No auth DB needed    │
+│   api_tokens tables  │           │                      │
+└──────────────────────┘           └──────────────────────┘
+```
+
+The console owns the credential database and handles all user/token
+CRUD.  Individual server nodes only need the JWT signing secret to
+validate session tokens.  Config-file tokens are validated locally
+without any database.
+
+### Proxy auth forwarding
+
+When the console proxies requests to server nodes (via `/node/{id}/...`
+routes), it uses a dedicated **service proxy token** with
+`aud: turnstone-server` and `write` scope.  The user's console JWT
+(which has `aud: turnstone-console`) is **not** forwarded — it would be
+rejected by the server's audience validation.
+
+The proxy token is managed by a `ServiceTokenManager` that auto-rotates
+1-hour JWTs, refreshing at 80% of lifetime.  If `--auth-token` is
+provided, that static token is used instead.
+
+### Service-to-service authentication
+
+The bridge and console collector use `ServiceTokenManager` for
+auto-rotating JWTs when communicating with server nodes:
+
+| Service | Identity | Scope | Audience | Purpose |
+|---------|----------|-------|----------|---------|
+| Bridge | `bridge` | `approve` | `turnstone-server` | Tool approval proxy, message relay |
+| Console collector | `console-collector` | `read` | `turnstone-server` | Node health polling |
+| Console proxy | `console-proxy` | `write` | `turnstone-server` | Proxied API calls |
+| Channel notify | `system` | `write` | `turnstone-channel` | Notification delivery to channel gateway |
+
+Service tokens use 1-hour expiry with automatic refresh via
+`ServiceTokenManager`.  The bridge injects auth headers per-request via
+httpx event hooks to ensure rotated tokens are picked up on SSE
+reconnects.
+
+Note that the channel gateway uses a distinct JWT audience
+(`turnstone-channel`) from the server (`turnstone-server`) and console
+(`turnstone-console`).  A server-scoped JWT cannot authenticate to the
+channel gateway endpoint, and vice versa.
+
+---
+
+## Configuration Reference
+
+### config.toml
+
+```toml
+[auth]
+enabled = true
+jwt_secret = "your-secret-key-here"
+jwt_expiry_hours = 24
+
+[[auth.tokens]]
+value = "tok_legacy"
+role = "full"
+```
+
+### Environment variables
+
+| Variable | Description |
+|----------|-------------|
+| `TURNSTONE_AUTH_ENABLED=1` | Enable authentication |
+| `TURNSTONE_AUTH_TOKEN=tok_xxx` | Register a config-file token with `full` access |
+| `TURNSTONE_JWT_SECRET=xxx` | JWT signing secret (must match across nodes) |
+| `TURNSTONE_CORS_ORIGINS=` | CORS allowed origins (comma-separated; empty = same-origin only) |
+
+---
+
+## Login Rate Limiting
+
+The `/api/auth/login` endpoint is protected by a dedicated
+`LoginRateLimiter` (separate from the general API rate limiter).
+Limits are enforced per-IP and per-username with a sliding window:
+
+- **5 attempts** per **5-minute window** per key
+- Failed logins record against both `ip:{client_ip}` and `user:{username}`
+- Returns `429 Too Many Requests` with `Retry-After` header when exceeded
+- Successful logins do not consume the budget
+
+---
+
+## CORS Policy
+
+By default, no CORS headers are sent (same-origin only). To allow
+cross-origin requests, set `TURNSTONE_CORS_ORIGINS`:
+
+```bash
+# Allow specific origins
+TURNSTONE_CORS_ORIGINS=https://app.example.com,https://admin.example.com
+
+# Allow all origins (development only)
+TURNSTONE_CORS_ORIGINS=*
+```
+
+When the variable is empty or unset, the CORS middleware is not added
+and browsers enforce same-origin policy.
+
+---
+
+## Security Properties
+
+- **Timing-safe comparison** for config-file tokens via
+  `hmac.compare_digest` — no timing side-channel.
+- **Hash-based lookup** for API tokens — the database stores only
+  SHA-256 hashes, eliminating timing attacks on token comparison.
+- **Local JWT validation** — no network call or database query needed
+  per request on server nodes.
+- **One-time display** of raw API tokens at creation. The plaintext is
+  never stored; `token_hash` never appears in API responses or logs.
+- **Structured logging audit trail** — `ctx_user_id` is set on every
+  authenticated request and injected into all log events.
+- **Scope enforcement** at the middleware layer before any handler
+  executes. Path-to-scope mapping is defined statically.
+- **JWT audience isolation** — server and console JWTs have distinct
+  `aud` claims, preventing cross-service token reuse.
+- **Login brute-force protection** — per-IP and per-username rate
+  limiting on the login endpoint.
+- **Secure cookies by default** — `Secure` flag set unconditionally;
+  24-hour max-age matches JWT expiry.
+- **CORS restriction** — no CORS headers by default (same-origin only).
+- **Service JWT auto-rotation** — 1-hour expiry with transparent
+  refresh, eliminating long-lived static tokens for inter-service auth.
+- **Secret strength validation** — warning logged when JWT secret is
+  shorter than 32 characters.

+
+**Lifecycle:**
+
+1. Model calls `watch(action="create", ...)` — persisted to SQLite.
+2. `WatchRunner` daemon polls for due watches every 15s.
+3. Each poll runs the command, evaluates the condition.
+4. When the condition fires (or max polls reached), the result is injected
+   as a synthetic user message and the watch auto-cancels.
+5. If the workstream was evicted, it is restored before injection.
+6. Watches survive server restart (overdue watches fire once on recovery).
+
+**Constraints:**
+
+- Max 5 active watches per workstream.
+- Poll interval: 10s–24h.
+- Output truncated at 64 KB.
+- Max 5 consecutive watch dispatches per worker thread (depth guard).
+- Duplicate names rejected within the same workstream.
+
+- **Auto-approve**: `create` requires approval; `list` and `cancel` are auto-approved.
+- **Agent availability**: Main session only — not available to plan/task sub-agents.

+> See [Watch Architecture](diagrams/png/18-watch-architecture.png) for the

+## Dynamic Tool Search
+
+When many MCP tools are connected, the total tool count can grow large enough to
+consume significant context window tokens and reduce model accuracy. Dynamic tool
+search addresses this by deferring tools the model is unlikely to need on the
+current turn and letting it search for them on demand.
+
+### Three-tier approach
+
+Tool search uses the best available mechanism for each provider:
+
+1. **Anthropic (native)** -- Models that support it receive `defer_loading: true`
+   on deferred tool definitions plus the `tool_search_tool_bm25_20251119` server-side
+   search tool. Anthropic's API handles search and expansion transparently.
+
+2. **OpenAI GPT-5.4+ (native)** -- Models with hosted tool search receive
+   `defer_loading: true` on deferred definitions. The API handles search internally.
+
+3. **vLLM / llama.cpp / NIM (client-side BM25)** -- A synthetic `tool_search`
+   function tool is injected into the tool list. When the model calls it,
+   `_exec_tool_search()` runs a pure-Python BM25 index over tool names and
+   descriptions, then expands the matched tools into the visible set.
+
+### Configuration
+
+Tool search is configured in `config.toml` under the `[tools]` section:
+
+```toml
+[tools]
+search = "auto"           # "auto", "on", or "off"
+search_threshold = 20     # minimum total tool count to activate
+search_max_results = 5    # max tools returned per search call
+```
+
+CLI flags override the config file:
+
+- `--tool-search {auto,on,off}` -- force tool search on or off, or let turnstone
+  decide based on threshold (default: `auto`).
+- `--tool-search-threshold N` -- minimum tool count to activate (default: 20).
+- `--tool-search-max-results N` -- max results per search (default: 5).
+
+### How it works
+
+1. **Threshold check**: At session startup, `ToolSearchManager.should_activate()`
+   counts total tools (built-in + MCP). If the count is below the threshold, tool
+   search stays off and all tools are sent to the model directly.
+
+2. **Partitioning**: When active, tools are split into two sets:
+   - **Always-on** -- the 18 built-in tools (members of `BUILTIN_TOOL_NAMES`).
+     These are always visible to the model.
+   - **Deferred** -- all MCP tools. These are not sent in the tool list unless
+     the model searches for them.
+
+3. **Search and expand**: When the model calls `tool_search` (client-side) or the
+   provider's native search returns results, the matched tools are added to the
+   visible set via `expand_visible()`. Once expanded, a tool stays visible for
+   the remainder of the session.
+
+4. **Multi-turn persistence**: Expanded tools are never removed. This avoids
+   confusing the model when it references a tool it discovered in an earlier turn.
+
+### Agent exemption
+
+Plan and task sub-agents do not use tool search. They operate on scoped tool
+sets (`AGENT_TOOLS` for plan agents, `TASK_AGENT_TOOLS` for task agents) with
+MCP tools merged in. Tool search is only active for the top-level session,
+where the model can interactively search for tools it needs.

+
+### Dynamic tool refresh
+
+MCP tool lists stay up-to-date without restart through three mechanisms:
+
+1. **Push notifications** -- MCP servers that declare `tools.listChanged: true` in
+   their capabilities send `notifications/tools/list_changed` when their tool list
+   changes. `MCPClientManager` registers a `message_handler` on each `ClientSession`
+   that triggers an immediate refresh for that server.
+
+2. **Periodic timer** -- Servers that do *not* support push notifications are polled
+   on a configurable interval (default 4 hours). The timer is staggered using a
+   launch-time seed (`monotonic_ns ^ pid`) so cluster nodes don't all hit MCP
+   servers simultaneously. Configure via `[mcp] refresh_interval` in `config.toml`
+   or `--mcp-refresh-interval SECONDS` on the CLI. Set to `0` to disable.
+
+3. **Manual** -- `/mcp refresh` re-fetches tools from all servers immediately.
+   `/mcp refresh <server>` targets a single server. If a server has disconnected,
+   manual refresh attempts reconnection.
+
+When tools change, `MCPClientManager` rebuilds its merged tool list using copy-on-write
+(new list/dict objects assigned atomically) and notifies all active `ChatSession`
+instances via registered listener callbacks. Each session rebuilds its `_tools`,
+`_task_tools`, `_agent_tools`, and reconstructs its `ToolSearchManager` (if active),
+preserving the set of previously expanded (discovered) tools.
+
+```toml

+
+## MCP Resources
+
+MCP servers can expose **resources** -- named data items (files, database rows,
+API responses) addressable by URI. turnstone discovers resources at startup and
+makes them available to the model via the `read_resource` built-in tool.
+
+### Discovery
+
+During the MCP `initialize` handshake, `MCPClientManager` checks each server's
+capabilities for the `resources` capability. For servers that declare it:
+
+1. `list_resources` fetches static resources (fixed URIs).
+2. `list_resource_templates` fetches URI templates (parameterized patterns like
+   `db://tables/{table}/rows/{id}`).
+
+Both are stored as `{uri, name, description, mimeType, server}` dicts and
+merged into a unified catalog.
+
+### Resource catalog in system message
+
+The first 50 resources are injected into the system message as an XML-delimited
+block so the model knows what URIs are available:
+
+```xml
+<mcp-resources>
+  file:///project/README.md  Project readme
+  db://users/schema  User table schema
+</mcp-resources>
+Use read_resource(uri='...') to access the resources listed above.
+```
+
+### read_resource tool
+
+| Parameter | Type   | Required | Description |
+|-----------|--------|----------|-------------|
+| `uri`     | string | yes      | The resource URI to read. |
+
+- **What it does**: Reads the resource from its MCP server via `MCPClientManager.read_resource_sync()`. Returns text content for text resources or base64-encoded data for binary resources. Output is truncated by the standard tool output limiter.
+- **Auto-approve**: No -- requires user confirmation (reads external data).
+- **Agent availability**: `agent` and `task_agent`.
+
+### Capability guards
+
+The `read_resource` tool schema is always loaded (it is a built-in JSON schema),
+but resource discovery only runs for servers that declare the `resources`
+capability. Servers without the capability contribute zero resources to the
+catalog.
+
+### Refresh
+
+Resource lists stay current through the same three-tier mechanism as tool lists:
+
+1. **Push** -- Servers declaring `resources.listChanged: true` send
+   `notifications/resources/list_changed`, triggering an immediate refresh.
+2. **Periodic** -- Servers without push are polled on the configured refresh
+   interval (default 4 hours, same timer as tools).
+3. **Manual** -- `/mcp refresh` re-fetches resources alongside tools.
+
+---
+
+## MCP Prompts
+
+MCP servers can also expose **prompts** -- reusable message templates with
+optional arguments. turnstone discovers prompts at startup for servers that
+declare the `prompts` capability.
+
+### Discovery
+
+Prompt discovery mirrors resource discovery: `list_prompts` is called during
+the `initialize` handshake. Each prompt is stored with its prefixed name
+(`mcp__{server}__{prompt}`), description, and argument schema.
+
+### use_prompt tool
+
+| Parameter   | Type   | Required | Description |
+|-------------|--------|----------|-------------|
+| `name`      | string | yes      | The prompt name (e.g. `mcp__server__prompt_name`). |
+| `arguments` | object | no       | Key-value argument pairs for the prompt. Values must be strings. |
+
+- **What it does**: Invokes an MCP prompt template by name via `MCPClientManager.get_prompt_sync()`, expanding it into messages. Returns the expanded prompt content formatted as `[role]: content` blocks joined with blank lines. The prompt catalog is listed in the system message so the model knows which prompts are available. Output is truncated by the standard tool output limiter.
+- **Auto-approve**: No -- requires user confirmation (invokes external prompt servers).
+- **Agent availability**: `agent` and `task_agent`.
+
+### Invocation
+
+`MCPClientManager.get_prompt_sync()` calls the server's `get_prompt` method
+with the provided arguments and returns the expanded messages. The `use_prompt`
+built-in tool exposes this to the model as a function call.
+
+### Governance Sync
+
+Discovered MCP prompts are automatically synced into the `prompt_templates`
+governance table as first-class governed templates:
+
+- **Origin tracking**: MCP-sourced templates have `origin="mcp"` and
+  `mcp_server` set to the server name. Manual templates have
+  `origin="manual"`.
+- **Read-only**: MCP-sourced templates are `readonly=True`. The admin API
+  returns 403 on update/delete attempts. The admin UI disables edit/delete
+  buttons and shows an origin badge.
+- **Precedence**: If a manual template and MCP prompt share the same name,
+  the manual template wins and the MCP prompt is skipped (with a log
+  warning).
+- **Lifecycle**: Templates are created on connect, updated on prompt list
+  refresh, and removed when the MCP server no longer exposes the prompt.
+  The sync runs automatically on connect, on `PromptListChangedNotification`,
+  and on manual `/mcp refresh`.
+- **Schema**: Migration 009 adds `origin`, `mcp_server`, and `readonly`
+  columns to the `prompt_templates` table.
+
+The `use_prompt` tool allows the model to invoke any discovered MCP prompt at
+runtime. A catalog of up to 30 prompts is injected into the system message
+inside `<mcp-prompts>` XML tags so the model can discover available prompts.
+
+---
+
+## MCP UI Visibility
+
+MCP server, resource, and prompt counts are surfaced across the UI:
+
+- **Server `/health` endpoint**: Returns `mcp.servers`, `mcp.resources`,
+  `mcp.prompts` when MCP is configured
+- **Server UI**: Magenta status badge in the header showing server count,
+  with resource/prompt counts in tooltip
+- **Console cluster status bar**: MCP metrics (servers/resources/prompts)
+  with magenta LED dot indicator, shown after a divider from workstream
+  metrics
+- **Console node detail**: Per-node MCP summary showing server, resource,
+  and prompt counts
+- **Console collector**: Aggregates MCP counts across all nodes in the
+  cluster overview
+
+MCP indicators use the `--magenta` design token for consistent theming
+across light and dark modes.
