+# 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
+
+ Turnstone Bootstrap Wizard  v0.5.4
+ ────────────────────────────────────────────────
+
+ Which provider for this wizard?
+   [1] OpenAI
+   [2] Anthropic
+   [3] OpenAI-compatible (local/vLLM)

+
+ Base URL [http://localhost:8000/v1]:

+ 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.

-Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports. Native deferred tool loading for Anthropic and OpenAI APIs reduces token overhead and improves tool selection accuracy when MCP servers expose many tools; local models (vLLM, llama.cpp) get a transparent client-side BM25 fallback.

+Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports. It runs as:
 
 - **Interactive sessions** — terminal CLI or browser UI with parallel workstreams
 - **Queue-driven agents** — trigger workstreams via message queue, stream progress, approve or auto-approve tool use
 - **Multi-node clusters** — generic work load-balances across nodes, directed work routes to a specific server
-- **Cluster dashboard** — real-time view of all nodes and workstreams, workstream creation with node targeting, reverse proxy for server UIs (only the console port needs network access)
+- **Cluster dashboard** — real-time view of all nodes and workstreams, reverse proxy for server UIs
+- **Intent validation** — an LLM judge evaluates every tool call before approval, presenting risk assessments and evidence-based recommendations so users can make informed decisions instead of blindly approving raw tool calls
+- **Governance & compliance** — RBAC, tool policies, prompt templates, workstream templates, usage tracking, and append-only audit logs
 - **Cluster simulator** — test the stack at scale (up to 1000 nodes) without an LLM backend
 
+Works with any OpenAI-compatible API (vLLM, llama.cpp, NVIDIA NIM) or Anthropic's native Messages API. Supports [MCP](https://modelcontextprotocol.io/) for external tool servers with native deferred tool loading on Anthropic and OpenAI APIs (BM25 fallback for local models).

+### 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.

+(same schema as above but with `tier: "heuristic"`), and the event gains a

+## 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).

 All five views receive live updates via SSE — state cards update counts, node rows update metrics, workstream rows update state indicators.
 
+The browser maintains a local `clusterState` object that mirrors the cluster snapshot. It is initialized from the SSE `snapshot` event on connect (or via `GET /v1/api/cluster/snapshot` on initial page load) and updated incrementally by SSE events. View navigation reads from local state — no API round-trips needed after the initial snapshot.

+# 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()`
+- `get_usage(since, group_by=...)`, `get_audit(action=..., limit=...)`
+
+**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.

+Results are injected back into the conversation as synthetic user messages,
+triggering the model to respond and act. Use for monitoring CI/CD pipelines,

+|-------------|---------|----------|-------------|
+| `action`    | string  | yes      | `create`, `list`, or `cancel`. |
+| `command`   | string  | create   | Shell command to poll periodically. |

+| `max_polls` | integer | no       | Max poll cycles before auto-cancel. Default: 100. |
+
+**Actions:**
+
+- `create` — Start a new watch. Requires approval (same as bash — runs shell
+  commands). Persists to the `watches` table; the server-level `WatchRunner`
+  daemon polls every 15 seconds for due watches.
+- `list` — Show all active watches in this workstream. Auto-approved.
+- `cancel` — Stop a watch by name or ID prefix. Auto-approved.
+
+**Stop condition DSL** — The `stop_on` parameter accepts a Python expression
+evaluated after each poll. Available variables:
+
+| Variable      | Type       | Description |
+|---------------|------------|-------------|
+| `output`      | `str`      | stdout (+stderr) of the command. |
+| `data`        | `Any`      | `json.loads(output)`, or `None` if not valid JSON. |
+| `exit_code`   | `int`      | Process exit code. |
+| `prev_output` | `str|None` | Previous poll's stdout (`None` on first poll). |
+| `changed`     | `bool`     | `True` if output differs from previous poll. |
+
+Safe builtins: `len`, `str`, `int`, `float`, `bool`, `abs`, `min`, `max`,
+`any`, `all`, `isinstance`, `sorted`. No `import`, `open`, `exec`, or
+`eval`. Security model: equivalent to `bash` — the model already has shell
+access.
+
+**Examples:**
+```
+data["state"] == "MERGED"
+"error" in output
+exit_code != 0
+changed and "ready" in output.lower()
+data.get("mergedAt") is not None
+```
+
+**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.

+
+## 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.
