 ### 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
+- **OIDC SSO** — single sign-on via any OpenID Connect provider (Okta, Azure AD, Google, Keycloak); Authorization Code Flow with PKCE, auto-provisioning, claim-based role mapping with demotion propagation; see [docs/oidc.md](docs/oidc.md)
 - **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
+- **Skills** — reusable behavioral profiles with system prompts, `{{variable}}` substitution, session config (model, temperature, token budget), install-time security scanning, version history, external discovery (skills.sh / GitHub), and runtime `skill` tool for model-driven skill activation
 - **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.
+All governance features are managed through the console admin panel (13 tabs) and the full REST API. Runtime settings (model, tools, rate limiting, health, judge, memory) are configurable via the admin Settings tab — no config file edits or restarts needed for most changes.

 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.

+Skills are also scanned at install time — the scanner evaluates content, supply chain, vulnerability, and declared capability risk across four independent axes. Results populate `scan_status` (tier) and `scan_report` (structured JSON breakdown) on the skill record so administrators can assess risk before enabling a skill.

-
-### 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.
+  and disables edit/delete for MCP-sourced skills.
+- **Spec fields**: Skills support the full Agent Skills standard frontmatter:
+  `name`, `description`, `license`, `compatibility`, `metadata` (author, version),
+  `allowed-tools`. The `license` and `compatibility` fields are preserved on import
+  and editable in the admin UI. See https://agentskills.io/specification.
+- **Security scanning**: Skills are automatically scanned at creation and update
+  time. The scanner evaluates four risk axes: content risk (command execution,
+  data exfiltration), supply chain risk (pipe-to-shell, transitive installs),
+  vulnerability risk (prompt injection, insecure credentials), and declared
+  capability risk (from `allowed-tools` in SKILL.md). Results populate the `scan_status`
+  (safe/low/medium/high/critical) and `scan_report` (JSON breakdown) columns.
+  These fields are system-managed and cannot be overwritten via the admin API.
+- **Discovery**: External skills can be discovered and installed from registries:
+  - `GET /v1/api/admin/skills/discover?q=...` — search the skills.sh registry
+    (or a custom registry via `skills.discovery_url` setting)
+  - `POST /v1/api/admin/skills/install` — install from skills.sh or GitHub.
+    Fetches the `SKILL.md` file, parses YAML frontmatter, creates a skill with
+    `origin="source"` and `readonly=True`, stores bundled resources.
+  - Admin UI: Skills tab has "Installed" / "Discover" pill toggle.
+    Discovery view has search bar, result cards, and "Import from GitHub" modal.
+  - SDK: `discover_skills(q)` and `install_skill(source, skill_id=..., url=...)`
+    on both Python and TypeScript console clients.
+- **Runtime config on installed skills**: Installed (readonly) skills can have
+  their runtime configuration edited — model, temperature, reasoning effort,
+  token budget, max tokens, agent max turns, auto-approve, allowed tools,
+  and enabled flag. The server restricts updates to these fields only via
+  `_SKILL_RUNTIME_CONFIG_FIELDS` filtering; spec/content fields (name,
+  description, tags, license, compatibility, content, activation) remain
+  immutable. The admin UI shows "Save Config" instead of "Save" for these
+  skills. Audit action: `skill.update.config`.
+- **Admin UI**: Create/Edit skill modals use a two-column spec manifest layout
+  (left: Identity / Manifest / Deployment; right: Skill Content editor with
+  monospace font). Runtime Config is a collapsible 3-column grid below.
+  License uses an SPDX identifier dropdown (MIT, Apache-2.0, GPL-3.0, etc.).
+  Installed skills show a cyan origin badge with source URL, spec fields are
+  disabled, and all collapsible sections auto-expand in view mode.

+  than vetted registries. Socket flags this as supply-chain critical in 36%

+  feeds into an interpreter (Snyk W011 pattern — indirect prompt injection
+  surface).
+- **`interpreter-exec`**: Running a script file whose content hasn't been
+  inspected. Opaque to command-level heuristics.
+- **`cloud-infra-mutation`**: Distinguishes destructive cloud CLI verbs
+  (`create`, `delete`, `destroy`) from read-only ones (`show`, `list`, `get`).

-this dataset to:
+Skills are evaluated by a content scanner at creation and update time. The
+scanner runs the same class of pattern analysis as the heuristic rules but
+operates on SKILL.md content rather than individual tool calls. It evaluates
+four independent risk axes:
+
+1. **Content risk** — command execution scope, external downloads, credential
+   handling, eval/exec, sudo, data exfiltration, browser automation
+2. **Supply chain risk** — pipe-to-shell, transitive installs (`npx skills add`),
+   obfuscation, download-execute chains, executable URLs from untrusted domains
+3. **Vulnerability risk** — prompt injection patterns, insecure credential
+   handling, third-party content exposure (indirect prompt injection surface)
+4. **Declared capability risk** — parsed from `allowed-tools` in the skill's SKILL.md.
+   `Bash(*)` (unrestricted shell) is high risk. `Bash(git:*)` is low.
+   Read-only tools are safe.
+
+Results are stored in `scan_status` (tier: safe/low/medium/high/critical) and
+`scan_report` (JSON breakdown) on the `prompt_templates` table. These fields are
+system-managed and not editable via the admin API.
+
+The scanner is a pure function (~2ms) with no I/O. It runs synchronously in
+the storage layer. Scanner failures are silently caught to never block skill
+creation.
+
+See [docs/governance.md](governance.md) for the skill governance model.
+
+---
+
+## Output Guard
+
+The output guard evaluates tool execution results *after* execution but *before*
+they enter the conversation context. It catches content-level threats that the
+input heuristic (which evaluates commands) cannot see — prompt injection
+payloads in fetched web pages, credential leakage in command output, encoded
+payloads, and adversarial URLs.
+
+The guard runs as a synchronous heuristic on the tool result text with a
+configurable time budget (default 5 seconds). Pattern checks run in priority
+order: prompt injection first, then credentials, then encoded payloads, then
+lower-priority checks. If the budget is exhausted mid-evaluation, whatever
+flags have been found so far are returned.
+
+The guard **annotates but does not gate** — it surfaces warnings via the
+`on_output_warning` SSE event and optionally redacts detected credentials
+from the output before it enters the conversation.
+
+### Detection priorities
+
+| Priority | Category | Risk | Examples |
+|----------|----------|------|----------|
+| 1 | Prompt injection | high | Override phrases, role injection (`{"role":"system"}`), instruction override markers |
+| 2 | Credential leakage | high | API keys, private key blocks, connection strings, `.env` format secrets |
+| 3 | Encoded payloads | medium | Script data URIs, hex shellcode sequences |
+| 4 | Adversarial URLs | medium | Cloud metadata endpoints, credential-bearing query parameters |
+| 5 | System info disclosure | low | Private IP addresses, sensitive file paths |
+
+### Credential redaction
+
+When `redact_secrets` is enabled (default), detected credentials in tool output
+are replaced with `[REDACTED:<type>]` markers before the output enters the
+conversation. The original unredacted output is never shown to the model.
+Redaction types: `api_key`, `private_key`, `password`, `secret`.
+
+### Configuration
+
+```toml
+[judge]
+output_guard = true    # enable output evaluation (default)
+redact_secrets = true  # auto-redact detected credentials (default)
+```
+
+Configurable at runtime via the admin Settings tab.
+
+### SSE event: `output_warning`
+
+When the output guard detects risk signals, an `output_warning` SSE event is
+emitted to the frontend:
+
+```json
+{
+  "type": "output_warning",
+  "call_id": "call_abc123",
+  "func_name": "bash",
+  "risk_level": "high",
+  "flags": ["credential_leak"],
+  "annotations": ["API key detected (sk-proj-...)"],
+  "output_length": 1024,
+  "redacted": true
+}
+```
+
+The web UI renders this as an inline warning after the tool result. The CLI
+shows a colored terminal warning. The MQ bridge forwards it as an
+`OutputWarningEvent` for console subscribers.
+
+Assessments are persisted to the `output_assessments` table for v2
+calibration. Raw tool output is never stored — only metadata (flags, risk
+level, annotations, output length, redaction status).
+
+### Session-level skill scan warning
+
+When a skill with `scan_status` of `high` or `critical` is loaded into a
+session, a warning is emitted via `on_info`:
+
+```
+⚠ Skill 'my-skill' has scan status: high.
+Review scan report in admin panel before enabling in production.
+```
+
+This ensures operators see a warning even if they missed the scan badge in
+the admin skills tab.
+
+---
+
+## Data Collection for v2 Calibration
+
+All three evaluation systems persist their assessments for future calibration:
+
+| Table | Source | Key columns |
+|-------|--------|-------------|
+| `intent_verdicts` | Intent judge (heuristic + LLM) | `func_name`, `risk_level`, `confidence`, `user_decision` |
+| `output_assessments` | Output guard | `func_name`, `risk_level`, `flags`, `redacted` |
+| `prompt_templates` | Skill scanner | `scan_status`, `scan_report`, `scan_version` |
+
+Run v1 with all tools requiring manual approval to build a local dataset.
+In v2, calibration tooling will analyze this data to:
 
 - Identify tools that are always approved (candidates for auto-approve policies)
-- Detect false positives in heuristic rules
+- Detect false positives in heuristic rules (intent + output guard)
 - Measure LLM judge accuracy against human decisions
 - Recommend policy changes to reduce approval fatigue
+- Tune output guard sensitivity per tool (e.g., `bash` output needs more
+  scrutiny than `read_file`)
+
+Output assessments are queryable via `GET /v1/api/admin/output-assessments`
+(requires `admin.judge` permission). Skills can be re-scanned via
+`POST /v1/api/admin/skills/{id}/rescan` when the scanner is updated.
 
 This data-driven approach means v1 is both useful on its own and a foundation
 for automated policy tuning.

+# MCP Registry Integration
+
+Turnstone integrates with the [official MCP Registry](https://registry.modelcontextprotocol.io) to let administrators discover and install MCP servers directly from the console admin panel.
+
+## Overview
+
+The MCP Registry is maintained by the [Agentic AI Foundation](https://www.linuxfoundation.org/press/linux-foundation-announces-the-formation-of-the-agentic-ai-foundation) (Linux Foundation) and serves as the canonical discovery layer for MCP servers. Turnstone queries its REST API (v0.1) for server metadata and provides a one-click install flow.
+
+Three sources of MCP servers coexist in Turnstone:
+
+| Source | Badge | Description |
+|--------|-------|-------------|
+| **Config** | `CONFIG` (magenta) | Imported from `config.toml` or JSON file. Read-only in admin UI. |
+| **Manual** | `MANUAL` (cyan) | Added through the admin UI or API. Full CRUD. |
+| **Registry** | `REGISTRY` (green) | Installed from the MCP Registry. Tracked by `registry_name`. |
+
+## Admin UI
+
+The MCP admin tab has two views, toggled by a pill selector:
+
+### Servers View
+
+Lists all installed MCP servers regardless of source. Each server shows:
+
+- **Source badge** — CONFIG, MANUAL, or REGISTRY
+- **Transport badge** — stdio or streamable-http
+- **Tool/resource/prompt counts** — aggregated across cluster nodes
+- **Per-node connection status** — connected (magenta dot), error (red), disabled (gray)
+- **Actions** — Edit / Delete (DB-managed servers only)
+
+Clicking a server name opens the detail modal. For registry-installed servers, the detail modal includes a **Registry** section showing the registry name, installed version, description, and website link.
+
+### Registry View
+
+Search and browse the MCP Registry. Switching to this view auto-loads a listing. Type a query and press Enter or click Search to filter.
+
+Each result card shows:
+
+- **Server name and description**
+- **Source type badges** — remote (streamable-http), npm, pypi
+- **Version number**
+- **Install / Installed / Update button**
+
+#### Install flow
+
+- **One-click**: Remote servers with no required headers or URL variables install immediately — no modal, no form. The server is added to the database, all cluster nodes are notified, and a toast confirms success.
+
+- **Modal**: Servers that require configuration (API keys, headers, URL template variables) or offer multiple install sources (both remote and package) open an install modal with:
+  - Source selector (radio group) — only shown when both remote and package are available
+  - Dynamic form fields for required/optional configuration
+  - Secret fields rendered as password inputs
+
+## Configuration
+
+### Registry URL
+
+By default, Turnstone queries `https://registry.modelcontextprotocol.io`. Override this for enterprise or private registries:
+
+**Via admin Settings tab:**
+
+Set `mcp.registry_url` to your registry's base URL.
+
+**Via config.toml:**
+
+```toml
+[mcp]
+registry_url = "https://registry.internal.example.com"
+```
+
+The resolution order is: database setting > config.toml > default.
+
+## API Endpoints
+
+Both endpoints require `admin.mcp` permission.
+
+### Search
+
+```
+GET /v1/api/admin/mcp-registry/search?search=github&limit=20&cursor=...
+```
+
+Query parameters:
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `search` | string | `""` | Search query. Empty returns a browsable listing. |
+| `limit` | integer | `20` | Results per page (max 100). |
+| `cursor` | string | — | Opaque cursor from `next_cursor` for pagination. |
+
+The response annotates each server with `installed`, `installed_server_id`, `installed_version`, and `update_available` by cross-referencing the `mcp_servers` table.
+
+### Install
+
+```
+POST /v1/api/admin/mcp-registry/install
+```
+
+```json
+{
+  "registry_name": "io.example/mcp-server",
+  "source": "remote",
+  "index": 0,
+  "name": "",
+  "variables": {},
+  "env": {"API_KEY": "sk-..."},
+  "headers": {"Authorization": "Bearer ..."}
+}
+```
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `registry_name` | Yes | Server name from registry search results. |
+| `source` | Yes | `"remote"` (streamable-http) or `"package"` (npm/pypi). |
+| `index` | No | Which remote or package entry to use (default `0`). |
+| `name` | No | Custom server name. Auto-derived from registry name if empty. |
+| `variables` | No | Values for URL template `{var}` placeholders. |
+| `env` | No | Environment variable values for package servers. |
+| `headers` | No | Header values for remote servers. |
+
+On success, the server is created in the database and all cluster nodes are automatically reloaded. Returns the created `McpServerDetail`.
+
+Errors: `400` (validation), `404` (not found in registry), `409` (already installed or name collision), `502` (registry unreachable).
+
+## SDK
+
+### Python
+
+```python
+from turnstone.sdk.console import TurnstoneConsole
+
+with TurnstoneConsole("http://localhost:8081", token="...") as client:
+    # Search
+    results = client.search_mcp_registry(q="github", limit=10)
+    for srv in results.servers:
+        print(f"{srv.name} v{srv.version} - {srv.description}")
+
+    # Install a remote server
+    detail = client.install_from_registry(
+        "io.example/mcp-server",
+        "remote",
+        headers={"Authorization": "Bearer sk-..."},
+    )
+    print(f"Installed: {detail.name}")
+```
+
+### TypeScript
+
+```typescript
+import { TurnstoneConsole } from "@anthropic/turnstone-sdk";
+
+const client = new TurnstoneConsole({
+  baseUrl: "http://localhost:8081",
+  token: "...",
+});
+
+// Search
+const results = await client.searchMcpRegistry({ q: "github", limit: 10 });
+for (const srv of results.servers) {
+  console.log(`${srv.name} v${srv.version} - ${srv.description}`);
+}
+
+// Install
+const detail = await client.installFromRegistry({
+  registry_name: "io.example/mcp-server",
+  source: "remote",
+  headers: { Authorization: "Bearer sk-..." },
+});
+```
+
+## Storage
+
+Registry-installed servers are stored in the existing `mcp_servers` table with three additional columns (migration 019):
+
+| Column | Type | Description |
+|--------|------|-------------|
+| `registry_name` | TEXT (nullable, unique) | Reverse-DNS name from the registry (e.g. `io.example/mcp-server`). |
+| `registry_version` | TEXT | Version at time of install. |
+| `registry_meta` | TEXT (JSON) | Snapshot of description, title, website, icons for display. |
+
+The partial unique index on `registry_name` prevents duplicate installs while allowing multiple non-registry servers with `NULL` registry_name.
+
+## Package Type Support
+
+| Registry Type | Transport | Command | Status |
+|--------------|-----------|---------|--------|
+| Remote (streamable-http) | `streamable-http` | — (URL-based) | Supported |
+| `npm` | `stdio` | `npx -y @scope/package@version` | Supported |
+| `pypi` | `stdio` | `uvx package==version` | Supported |
+| `oci` | — | — | Not supported (no runtime available) |
+| `nuget` | — | — | Not supported |
+| `mcpb` | — | — | Not supported |
+
+For `npm` and `pypi` packages, the corresponding runtime (`node`/`npx` or `python`/`uvx`) must be available on the cluster nodes. Connection failures due to missing runtimes appear in the per-node MCP status display.

+# Structured Memory
+
+> See also: [Memory Architecture diagram](diagrams/png/23-memory-architecture.png)
+
+The structured memory system gives the AI persistent, typed, scoped memories
+that survive across sessions and workstreams. Memories are automatically
+surfaced in the system message via BM25 relevance scoring, so the model has
+contextual recall without explicit search.
+
+## Overview
+
+Each memory has three dimensions:
+
+- **Type** -- categorizes the memory's purpose
+- **Scope** -- controls visibility boundaries
+- **Name** -- unique identifier within a scope (snake_case, normalized)
+
+### Memory types
+
+| Type        | Purpose                                                    |
+|-------------|------------------------------------------------------------|
+| `user`      | User preferences, conventions, working style               |
+| `project`   | Project-specific knowledge, architecture, patterns         |
+| `feedback`  | Corrections, lessons learned, things to avoid              |
+| `reference` | Reference material, documentation, specifications         |
+
+### Memory scopes
+
+| Scope        | Visibility                                                |
+|--------------|-----------------------------------------------------------|
+| `global`     | Visible to all workstreams and users                      |
+| `workstream` | Visible only within the originating workstream            |
+| `user`       | Follows the authenticated user across workstreams         |
+
+A memory's identity is the tuple `(name, scope, scope_id)`. Saving a memory
+with the same identity upserts -- updating content while preserving the ID.
+
+### BM25 relevance injection
+
+On every conversation turn, the system:
+
+1. Fetches up to `fetch_limit` memories visible in the current scope
+2. Extracts context from the last 3 user messages
+3. Scores memories against that context using a BM25 index
+4. Injects the top `relevance_k` memories into the system message as
+   `<memories>` XML tags
+5. Appends a hint telling the model how many memories are in scope
+
+This means the model always has its most relevant memories available without
+explicit recall -- but can still use `memory(action='search')` for deeper
+lookup.
+
+### Nudges
+
+The metacognition layer can nudge the model to save memories at appropriate
+moments (e.g., after a correction or when resuming a workstream). Nudges are
+rate-limited by `nudge_cooldown` and can be disabled entirely.
+
+---
+
+## Configuration
+
+### config.toml
+
+```toml
+[memory]
+relevance_k = 5          # top-k memories injected per turn
+fetch_limit = 50          # max memories fetched from storage for scoring
+max_content = 32768       # max content length per memory (characters)
+nudge_cooldown = 300      # minimum seconds between memory nudges
+nudges = true             # enable/disable metacognitive nudges
+```
+
+All fields are optional. Defaults are shown above.
+
+---
+

+Memories are stored in the `structured_memories` table (migration 013).
+The unique constraint on `(name, scope, scope_id)` ensures upsert semantics.
+The name is normalized on save: lowercased, hyphens and spaces replaced with
+underscores.

+# OpenID Connect (OIDC) Single Sign-On
+
+Turnstone supports OpenID Connect for federated authentication, allowing
+users to log in with their existing corporate identity provider instead of
+managing a separate password. OIDC is opt-in: when configured, the login
+screen shows a "Continue with SSO" button alongside the existing
+username/password form. When not configured, the login experience is
+unchanged.
+
+Any OIDC-compliant provider works: Google, Okta, Azure AD, Keycloak,
+Auth0, OneLogin, and others that publish a
+`.well-known/openid-configuration` discovery document.
+
+---
+
+## Prerequisites
+
+1. A registered **confidential** OIDC client at your identity provider
+2. The client's redirect URI must include:
+   `https://your-turnstone-host/v1/api/auth/oidc/callback`
+3. A local admin user must exist in Turnstone (complete the initial setup
+   wizard before enabling OIDC)
+
+---
+
+## Configuration
+
+OIDC is configured via environment variables (preferred) or the `[oidc]`
+section of `config.toml`. Environment variables take precedence when both
+are set.
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| `TURNSTONE_OIDC_ISSUER` | Yes | — | Issuer URL (e.g. `https://accounts.google.com`). Must serve `/.well-known/openid-configuration`. |
+| `TURNSTONE_OIDC_CLIENT_ID` | Yes | — | OAuth 2.0 client ID from your provider |
+| `TURNSTONE_OIDC_CLIENT_SECRET` | Yes | — | OAuth 2.0 client secret (confidential client) |
+| `TURNSTONE_OIDC_SCOPES` | No | `openid email profile` | Space-separated OAuth scopes to request |
+| `TURNSTONE_OIDC_PROVIDER_NAME` | No | `SSO` | Display name for the login button (e.g. "Google", "Okta") |
+| `TURNSTONE_OIDC_ROLE_CLAIM` | No | — | ID token claim containing role/group values (see [Role Mapping](#role-mapping)) |
+| `TURNSTONE_OIDC_ROLE_MAP` | No | — | Mapping from claim values to Turnstone role IDs (see [Role Mapping](#role-mapping)) |
+| `TURNSTONE_OIDC_PASSWORD_ENABLED` | No | `true` | Set to `false` to hide the password form and block all username/password logins (including admin). API tokens and config-file tokens still work. |
+| `TURNSTONE_OIDC_REDIRECT_BASE` | No | — | Externally-reachable origin for the OIDC redirect URI (e.g. `https://app.example.com`). Recommended when running behind a reverse proxy. When unset, derived from the request Host header. |
+
+OIDC is enabled when all three required fields (issuer, client ID, client
+secret) are non-empty. If any is missing, OIDC is silently disabled and
+the login screen shows only the password form.
+
+### Reverse Proxy / Load Balancer
+
+When Turnstone runs behind a reverse proxy, the internal `Host` header may
+not match the externally-reachable URL. Set `TURNSTONE_OIDC_REDIRECT_BASE`
+to the public origin so the redirect URI sent to the identity provider is
+correct:
+
+```bash
+TURNSTONE_OIDC_REDIRECT_BASE=https://app.example.com
+```
+
+The resulting callback URL will be
+`https://app.example.com/v1/api/auth/oidc/callback` — register this as the
+authorized redirect URI in your identity provider.
+
+### config.toml alternative
+
+```toml
+[oidc]
+issuer = "https://accounts.google.com"
+client_id = "your-client-id"
+client_secret = "your-client-secret"
+scopes = "openid email profile"
+provider_name = "Google"
+role_claim = "groups"
+password_enabled = true
+redirect_base = "https://app.example.com"
+
+[oidc.role_map]
+admin = "builtin-admin"
+engineering = "builtin-operator"
+```
+
+---

+3. Application type: **Web Application**
+4. Add sign-in redirect URI:
+   `https://your-turnstone-host/v1/api/auth/oidc/callback`
+5. Note the **Issuer** (your Okta domain, e.g.
+   `https://dev-123456.okta.com`)
+
+```bash
+TURNSTONE_OIDC_ISSUER=https://dev-123456.okta.com
+TURNSTONE_OIDC_CLIENT_ID=0oaXXXXXXXXXXXXX
+TURNSTONE_OIDC_CLIENT_SECRET=...

+   copy the value immediately
+4. The issuer URL is
+   `https://login.microsoftonline.com/{tenant-id}/v2.0`
+
+```bash
+TURNSTONE_OIDC_ISSUER=https://login.microsoftonline.com/YOUR_TENANT_ID/v2.0
+TURNSTONE_OIDC_CLIENT_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
+TURNSTONE_OIDC_CLIENT_SECRET=...

+1. In the Keycloak Admin Console, select your **Realm**
+2. Go to **Clients** > **Create client**
+3. Client type: **OpenID Connect**
+4. Set **Client authentication** to **On** (confidential)
+5. Add valid redirect URI:
+   `https://your-turnstone-host/v1/api/auth/oidc/callback`
+6. The issuer URL is
+   `https://keycloak.example.com/realms/your-realm`
+
+```bash
+TURNSTONE_OIDC_ISSUER=https://keycloak.example.com/realms/your-realm
+TURNSTONE_OIDC_CLIENT_ID=turnstone
+TURNSTONE_OIDC_CLIENT_SECRET=...
+TURNSTONE_OIDC_PROVIDER_NAME=Keycloak
+TURNSTONE_OIDC_ROLE_CLAIM=realm_access.roles
+TURNSTONE_OIDC_ROLE_MAP="admin:builtin-admin,operator:builtin-operator"
+```
+
+---
+
+## Role Mapping
+
+OIDC role mapping assigns Turnstone roles to users based on claims in the
+ID token. This is optional — without it, OIDC users are provisioned with
+the `builtin-viewer` role (read-only access) by default.
+
+### Configuration
+
+Set `TURNSTONE_OIDC_ROLE_CLAIM` to the name of the claim in the ID token
+that contains the user's group or role memberships. Then set
+`TURNSTONE_OIDC_ROLE_MAP` to map claim values to Turnstone role IDs.
+
+The role map is a comma-separated list of `claim_value:turnstone_role`
+pairs:
+
+```bash
+TURNSTONE_OIDC_ROLE_CLAIM=groups
+TURNSTONE_OIDC_ROLE_MAP="admin:builtin-admin,engineering:builtin-operator,viewer:builtin-viewer"
+```
+
+### Behavior
+
+- **Synced on every login**: roles are added when new claim values appear,
+  and OIDC-assigned roles are revoked when the corresponding claim value
+  is no longer present. Roles assigned manually (or by other sources) are
+  never touched — only roles with `assigned_by="oidc"` are subject to
+  revocation.
+- **List or string**: the claim value can be a JSON array
+  (`["admin", "engineering"]`) or a single string (`"admin"`). Both are
+  handled correctly.
+- **Unknown values**: claim values not present in the role map are silently
+  ignored.
+- **Missing roles**: if the role map references a Turnstone role ID that
+  does not exist in the database, the assignment is skipped (no error).
+- **Evaluated on every login**: roles are checked and applied each time
+  the user authenticates via OIDC, so new group memberships are picked
+  up on the next login.
+
+### Built-in Roles
+
+| Role ID | Permissions |
+|---------|-------------|
+| `builtin-admin` | All permissions |
+| `builtin-operator` | read, write, workstreams.create, workstreams.close |
+| `builtin-viewer` | read |
+
+---
+
+## User Provisioning
+
+When a user logs in via OIDC for the first time, Turnstone automatically
+creates a local user account:
+
+1. The OIDC identity (`issuer` + `sub` claim) is stored in the
+   `oidc_identities` table and linked to the new user
+2. The **username** is derived from the `preferred_username` claim,
+   falling back to the email local part, with deduplication if needed
+3. The **display name** comes from the `name` claim, falling back to
+   `preferred_username` or email
+4. The user's password hash is set to a sentinel value (`!oidc`) — OIDC
+   users cannot log in with a password
+
+On subsequent logins, the existing user is matched by `(issuer, sub)` and
+the `last_login` timestamp is updated. Role mapping is re-evaluated on
+every login.
+
+---
+
+## OIDC-Only Mode
+
+To enforce OIDC for all logins and hide the password form, set:
+
+```bash
+TURNSTONE_OIDC_PASSWORD_ENABLED=false
+```
+
+In this mode the login screen shows only the "Continue with SSO" button.
+The password form, token toggle, and sign-in button are all hidden.
+All username/password logins are blocked at the API level, including
+admin accounts.
+
+The first admin account must be created via the setup wizard (with a
+password) before OIDC is enabled. The setup wizard always works
+regardless of this setting because it is only available when zero users
+exist in the database.
+
+API token login (`POST /v1/api/auth/login` with a `ts_` token) and
+config-file tokens (`Authorization: Bearer tok_xxx`) continue to work
+regardless of this setting. OIDC-only mode affects password-based
+authentication only.
+
+---
+
+## Login Flow
+
+Both the server and console support OIDC login. The flow is identical:
+
+1. The browser fetches `GET /v1/api/auth/status` at page load
+2. If the response includes `oidc_enabled: true`, the login screen shows
+   a "Continue with {provider_name}" button
+3. Clicking the button navigates to `GET /v1/api/auth/oidc/authorize`
+4. Turnstone generates a state token, nonce, and PKCE verifier, stores
+   them in the database, and redirects the browser to the identity
+   provider's authorization endpoint
+5. The user authenticates at the identity provider
+6. The IdP redirects back to
+   `GET /v1/api/auth/oidc/callback?code=...&state=...`
+7. Turnstone validates the state, exchanges the authorization code for
+   tokens using the PKCE verifier, validates the ID token against the
+   provider's JWKS public keys, provisions or matches the user, and
+   issues a Turnstone JWT
+8. The browser is redirected to `/?oidc_success=1` with the JWT set in
+   an `HttpOnly` session cookie
+9. The browser JavaScript detects the `oidc_success` query parameter,
+   strips it from the URL, hides the login overlay, and calls
+   `onLoginSuccess()` to initialize the application
+
+---
+
+## API Endpoints
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| GET | `/v1/api/auth/oidc/authorize` | Public | Redirects to identity provider |
+| GET | `/v1/api/auth/oidc/callback` | Public | Handles IdP callback, issues JWT |
+
+Both endpoints are public (no authentication required) because they are
+part of the login flow itself.
+
+### Auth status response
+
+When OIDC is enabled, `GET /v1/api/auth/status` includes additional
+fields:
+
+```json
+{
+  "auth_enabled": true,
+  "has_users": true,
+  "setup_required": false,
+  "oidc_enabled": true,
+  "oidc_provider_name": "Google",
+  "password_enabled": true
+}
+```
+
+---
+
+## Database Schema
+
+Migration 018 creates two tables:
+
+```sql
+CREATE TABLE oidc_identities (
+    issuer      TEXT NOT NULL,
+    subject     TEXT NOT NULL,
+    user_id     TEXT NOT NULL,
+    email       TEXT NOT NULL DEFAULT '',
+    created     TEXT NOT NULL,
+    last_login  TEXT NOT NULL,
+    PRIMARY KEY (issuer, subject)
+);
+
+CREATE INDEX idx_oidc_identities_user_id ON oidc_identities(user_id);
+
+CREATE TABLE oidc_pending_states (
+    state          TEXT PRIMARY KEY,
+    nonce          TEXT NOT NULL,
+    code_verifier  TEXT NOT NULL,
+    audience       TEXT NOT NULL,
+    created_at     TEXT NOT NULL
+);
+```
+
+The `oidc_identities` table links an OIDC subject (identified by
+`issuer` + `subject`) to a Turnstone `user_id`. A single user can have
+multiple OIDC identities (e.g. from different providers).
+
+The `oidc_pending_states` table stores authorization flow state for
+callback validation. Entries are automatically cleaned up after 5 minutes.
+
+---
+
+## Security Notes
+
+- **Authorization Code Flow with PKCE**: the recommended OAuth 2.0 flow
+  for web applications. PKCE prevents authorization code interception
+  attacks even without a client secret (though the client secret is still
+  used for additional security).
+- **ID token validation**: all tokens are validated using the provider's
+  JWKS public keys (RS256 or ES256). The signature, issuer, audience,
+  and expiry are all checked.
+- **State parameter**: a cryptographically random state token prevents
+  CSRF attacks on the callback endpoint. The state is stored server-side
+  and verified on callback.
+- **Nonce**: a random nonce is included in the authorization request and
+  verified in the ID token to prevent replay attacks.
+- **Client secret**: never leaves the server — it is only used in the
+  server-to-IdP token exchange, not exposed to the browser.
+- **OIDC users cannot use password login**: the sentinel password hash
+  (`!oidc`) ensures `verify_password()` always rejects password attempts
+  for OIDC-provisioned users.
+- **Rate limiting**: the callback endpoint shares the login rate limiter
+  (5 attempts per 5-minute window per IP).
+- **State TTL**: pending authorization states expire after 5 minutes.
+  Expired states are lazily cleaned up on each callback.
+- **Setup guard**: OIDC login requires at least one local admin user to
+  exist. This ensures the initial admin account is always created via the
+  setup wizard with a password, not hijacked by an external identity.
+
+---
+
+## Troubleshooting
+
+### "OIDC not configured"
+
+All three required environment variables must be set:
+`TURNSTONE_OIDC_ISSUER`, `TURNSTONE_OIDC_CLIENT_ID`, and
+`TURNSTONE_OIDC_CLIENT_SECRET`. Check that none are empty or
+whitespace-only.
+
+### "Login session expired"
+
+The authorization flow must complete within 5 minutes. If the user takes
+too long at the identity provider, the pending state expires. Try again.
+
+### "Initial setup required"
+
+OIDC login is blocked until at least one local admin user exists.
+Complete the setup wizard first (navigate to the Turnstone URL and follow
+the prompts to create an admin user with a password).
+
+### Discovery fails at startup
+
+Check that the issuer URL is reachable from the Turnstone server and
+serves a valid `/.well-known/openid-configuration` document. The server
+logs the discovery attempt at startup:
+
+```
+OIDC discovery failed for https://your-issuer.example.com: ...
+```
+
+OIDC is automatically disabled when discovery fails. Restart the server
+after fixing the connectivity issue.
+
+### Redirect URI mismatch
+
+The redirect URI configured at the identity provider must exactly match
+`https://your-host/v1/api/auth/oidc/callback`. Common issues:
+
+- **Scheme mismatch**: the redirect uses `https://` — make sure TLS is
+  configured or a reverse proxy sets the `X-Forwarded-Proto` header
+- **Port mismatch**: if running on a non-standard port, include it in
+  the redirect URI
+- **Path mismatch**: the path must include the `/v1` API version prefix
+
+### User not assigned expected roles
+
+Check that:
+
+1. `TURNSTONE_OIDC_ROLE_CLAIM` matches the exact claim name in the ID
+   token (case-sensitive)
+2. `TURNSTONE_OIDC_ROLE_MAP` maps the correct claim values to valid
+   Turnstone role IDs
+3. The roles referenced in the map exist in the database (check the
+   admin panel > Roles tab)
+4. The identity provider is configured to include the claim in the ID
+   token (some providers require explicit scope or claim configuration)

+# OpenShell Sandbox Integration
+
+Turnstone can run inside an [OpenShell](https://github.com/NVIDIA/OpenShell)
+sandbox for kernel-enforced security boundaries around tool execution. OpenShell
+provides four layers of defense that Turnstone's application-level safety model
+does not cover:
+
+| Layer | Mechanism | What it prevents |
+|-------|-----------|------------------|
+| Filesystem | Landlock | Writes to `/etc`, `~/.ssh`, system paths |
+| Network | Network namespace + seccomp + HTTP CONNECT proxy | Connections to unlisted hosts |
+| Process | `setuid` drop + verification | Privilege escalation to root |
+| Credentials | Proxy-level secret resolution | API keys in sandbox memory |
+
+Turnstone's own safety layers (human approval, intent judge, tool policies,
+output guard) remain active inside the sandbox and handle threats at the semantic
+level -- what the LLM *means* to do with its legitimate access.
+
+> See also: [Security and Authentication](security.md),
+> [Intent Validation](judge.md), [Governance](governance.md)
+
+---
+
+## Quick Start
+
+```bash
+# Run turnstone-server in an OpenShell sandbox
+openshell sandbox run \
+  --policy deploy/openshell/turnstone-policy.yaml \
+  --workdir /path/to/project \
+  -- python3 -m turnstone.server --host 0.0.0.0 --port 8080
+```
+
+With inference routing (API keys never enter the sandbox):
+
+```bash
+openshell sandbox run \
+  --policy deploy/openshell/turnstone-policy.yaml \
+  --inference-routes deploy/openshell/routes.yaml \
+  --workdir /path/to/project \
+  -- python3 -m turnstone.server --host 0.0.0.0 --port 8080 \
+      --base-url https://inference.local
+```
+
+The `inference.local` hostname is intercepted by the OpenShell proxy before
+network policy evaluation -- no network policy entry is needed for it.
+
+---
+
+## Policy Files
+
+### `deploy/openshell/turnstone-policy.yaml`
+
+The main sandbox policy. Covers filesystem, process, and network rules.
+
+### `deploy/openshell/routes.yaml`
+
+Inference routing configuration. Maps `inference.local` to real LLM API
+backends. Uncomment and configure the provider(s) you use.
+
+---
+
+## Filesystem Policy
+
+The policy uses Landlock (Linux 5.13+) for kernel-enforced filesystem access
+control. Paths are locked at sandbox creation and cannot be changed at runtime.
+
+| Path | Access | Purpose |
+|------|--------|---------|
+| `--workdir` | read-write | Project files (auto-added via `include_workdir`) |
+| `/tmp` | read-write | Bash tool temp scripts, eval workdirs |
+| `/dev/null` | read-write | Shell redirections (`2>/dev/null`) |
+| `/var/log` | read-write | Log files |
+| `/usr`, `/lib`, `/lib64` | read-only | Python runtime, installed packages |
+| `/etc` | read-only | System config, SSL certificates |
+| `/proc`, `/dev/urandom` | read-only | Process info, entropy |
+| `~/.config/turnstone` | read-only | Config file (writes go to database) |
+
+Landlock runs in `best_effort` mode by default -- degrades gracefully on kernels
+without Landlock support. Set `compatibility: hard_requirement` for production
+hardened deployments.
+
+---
+
+## Network Policy
+
+Default-deny. Only explicitly listed host:port pairs are reachable. All child
+processes (MCP servers, bash commands, grep) inherit the network namespace and
+cannot bypass the proxy.
+
+### Included endpoints
+
+| Policy | Hosts | Purpose |
+|--------|-------|---------|
+| `openai_api` | `api.openai.com` | OpenAI LLM API |
+| `anthropic_api` | `api.anthropic.com` | Anthropic LLM API |
+| `tavily_api` | `api.tavily.com` | Web search fallback |
+| `skills_registry` | `skills.sh` | Skill discovery |
+| `github_api` | `api.github.com` (read-only L7), `raw.githubusercontent.com` | Skill fetch, GitHub API |
+| `mcp_registry` | `registry.modelcontextprotocol.io` (read-only L7) | MCP server discovery |
+| `redis` | `127.0.0.1:6379` | Message queue |
+| `web_fetch_common` | readthedocs, python docs, GitHub Pages, PyPI, npm, Stack Overflow, Wikipedia | Curated web_fetch domains |
+| `bash_network_tools` | Same as `web_fetch_common` | curl/wget from bash tool |
+| `package_registries` | `pypi.org`, `files.pythonhosted.org` | pip/uv package installs |
+| `git_operations` | `github.com`, `gitlab.com` (L7: clone/fetch only, no push) | Git read-only operations |
+
+### L7 enforcement
+
+Endpoints marked with `protocol: rest` and `tls: terminate` get HTTP-level
+inspection. The proxy TLS-terminates using an ephemeral per-sandbox CA, parses
+each request, and evaluates method + path against the rules.
+
+The `github_api`, `mcp_registry`, and `git_operations` policies use L7
+enforcement:
+
+- **GitHub API / MCP Registry**: `access: read-only` -- only GET, HEAD, OPTIONS
+  allowed
+- **Git operations**: explicit rules allowing only `info/refs` (GET) and
+  `git-upload-pack` (POST) -- clone and fetch work, push is blocked
+
+### Commented-out sections
+
+The policy includes commented blocks for optional integrations. Uncomment and
+configure as needed:
+
+- **OIDC** -- add your identity provider's hostname
+- **Discord** -- `discord.com`, `gateway.discord.gg`, `cdn.discordapp.com`
+- **MCP HTTP servers** -- any MCP servers using streamable-http transport
+
+---
+
+## Customizing the Domain Allowlist
+
+The `web_fetch` tool lets the LLM fetch arbitrary public URLs, but OpenShell
+cannot allow "all HTTPS" -- bare wildcard hosts are rejected by policy
+validation. Instead, the policy ships with a curated set of common reference
+domains.
+
+To add domains your workloads need:
+
+```yaml
+# In turnstone-policy.yaml, under web_fetch_common.endpoints:
+      - host: docs.example.com
+        port: 443
+
+# Also add to bash_network_tools.endpoints if curl/wget should reach it:
+      - host: docs.example.com
+        port: 443
+```
+
+Wildcard patterns are supported:
+
+- `*.example.com` -- matches one subdomain level (e.g. `api.example.com`)
+- `**.example.com` -- matches any depth (e.g. `deep.sub.example.com`)
+
+Unlisted domains return connection errors, which the LLM handles gracefully by
+telling the user it cannot reach that site.
+
+---
+
+## Inference Routing
+
+Inference routing keeps real API keys completely outside the sandbox. The
+sandbox process only sees opaque placeholder tokens in its environment
+(`openshell:resolve:env:ANTHROPIC_API_KEY`). The proxy rewrites these to real
+credentials on the wire before forwarding to the upstream API.
+
+### Setup
+
+1. Edit `deploy/openshell/routes.yaml` -- uncomment your provider:
+
+```yaml
+routes:
+  # OpenAI
+  - name: inference.local
+    endpoint: https://api.openai.com/v1
+    model: gpt-5
+    provider_type: openai
+    protocols:
+      - openai_chat_completions
+      - model_discovery
+    api_key_env: OPENAI_API_KEY
+
+  # Or Anthropic
+  - name: inference.local
+    endpoint: https://api.anthropic.com
+    model: claude-sonnet-4-6
+    provider_type: anthropic
+    protocols:
+      - anthropic_messages
+    api_key_env: ANTHROPIC_API_KEY
+```
+
+2. Start with `--inference-routes` and point turnstone at `inference.local`:
+
+```bash
+openshell sandbox run \
+  --inference-routes deploy/openshell/routes.yaml \
+  --base-url https://inference.local \
+  ...
+```
+
+3. When inference routing is active, the `openai_api` and `anthropic_api`
+   network policies can be removed from the sandbox policy -- the proxy handles
+   LLM traffic on a separate code path that bypasses OPA entirely.
+
+### Local model servers
+
+For local servers (vLLM, llama.cpp) with no authentication, omit both
+`api_key` and `api_key_env` from the route config. No credential resolution
+is needed.
+
+---
+
+## MCP Server Subprocesses
+
+MCP servers using stdio transport are spawned as child processes of turnstone.
+They automatically inherit all sandbox constraints:
+
+- **Network namespace** -- kernel-level, cannot be bypassed
+- **Landlock filesystem** -- kernel-level, cannot be relaxed
+- **Seccomp socket filter** -- kernel-level, inherited on fork
+
+No per-subprocess policy entries are needed for these constraints. However, if
+an MCP server makes outbound network requests (through the proxy), its binary
+must appear in a `binaries[]` entry for the relevant network policy. The proxy
+identifies the requesting process via `/proc/<pid>/exe` (not `argv[0]`, which
+is spoofable).
+
+Example for a Python-based MCP server that calls an external API:
+
+```yaml
+  mcp_external_api:
+    name: mcp-external
+    endpoints:
+      - host: api.example.com
+        port: 443
+    binaries:
+      - path: /usr/bin/python3*
+      - path: /usr/local/bin/python3*
+```
+
+MCP servers using streamable-http transport are remote -- they need a network
+policy entry for their host:port but no binary entry (the Python process making
+the HTTP call is already covered by the standard `python3*` binary entries).
+
+---
+
+## Security Model: Which Layer Enforces What
+
+```
+                      OpenShell (infrastructure)          Turnstone (application)
+                     ─────────────────────────────     ──────────────────────────────
+Filesystem access     Landlock kernel enforcement       (no enforcement)
+Network egress        Netns + seccomp + proxy + OPA     SSRF check on web_fetch
+Credentials           Placeholder injection + proxy     Output guard redaction
+Privilege level       setuid drop + verification        (no enforcement)
+Tool semantics        (no visibility)                   Heuristic + LLM judge
+Tool policies         (no visibility)                   fnmatch admin policies
+Prompt injection      (no visibility)                   Output guard detection
+Human approval        (no visibility)                   Approval gate + "always"
+```
+
+OpenShell constrains what the process can physically reach. Turnstone constrains
+what the LLM does with its legitimate access. Neither layer is sufficient alone:
+
+- Without OpenShell: a bash command can `curl` secrets to any endpoint, write to
+  `/etc/crontab`, or read `~/.ssh/id_rsa` -- all gated only by human approval
+- Without Turnstone: the LLM can `rm -rf` the entire workdir, run destructive
+  commands, or consume prompt injection payloads -- all within the sandbox's
+  allowed scope
+
+---
+
+## Hardening Checklist
+
+For production deployments:
+
+- [ ] Set `landlock.compatibility: hard_requirement`
+- [ ] Enable inference routing (removes API keys from sandbox)
+- [ ] Remove `openai_api`/`anthropic_api` network policies when using inference
+      routing (traffic goes through the router, not direct)
+- [ ] Review and trim `web_fetch_common` domains to your actual needs
+- [ ] Remove `package_registries` policy if pip/uv installs are not needed
+- [ ] Add your OIDC provider endpoint if using SSO
+- [ ] Set Redis `allowed_ips` to your actual Redis host if not localhost
+- [ ] Consider removing `bash_network_tools` entirely if bash should not have
+      network access

+
+Turnstone supports OIDC Authorization Code Flow with PKCE for

+environment variables are set. Users are auto-provisioned on first
+login.
+
+#### Configuration
+
+| Variable | Required | Description |

+| `TURNSTONE_OIDC_ISSUER` | Yes | OIDC issuer URL (e.g., `https://accounts.google.com`) |

+| `TURNSTONE_OIDC_ROLE_MAP` | No | Comma-separated `claim_value:role_id` pairs (e.g., `admin:builtin-admin,eng:builtin-operator`) |
+| `TURNSTONE_OIDC_PASSWORD_ENABLED` | No | Set to `false` to hide password login and force SSO-only |
+
+OIDC is enabled when all three required variables (`ISSUER`,
+`CLIENT_ID`, `CLIENT_SECRET`) are set.
+
+#### Login flow
+
+1. User clicks "Continue with [Provider]" on the login page
+2. `GET /v1/api/auth/oidc/authorize` generates state, nonce, and PKCE
+   challenge, stores them in the database, and redirects to the IdP
+3. User authenticates at the identity provider
+4. IdP redirects to `/v1/api/auth/oidc/callback` with `code` + `state`
+5. Server validates state, exchanges the authorization code (with PKCE
+   verifier), and validates the ID token (JWKS signature, issuer,
+   audience, nonce)
+6. Provisions or matches the user by `(issuer, sub)` — never by
+   username or email
+7. Issues a JWT (`src: oidc`), sets a session cookie, and redirects to
+   the application
+
+#### Security measures
+
+- **PKCE (S256)** — prevents authorization code interception
+- **State parameter** — one-time use, 5-minute TTL, database-backed
+  (multi-node safe)
+- **Nonce** — prevents ID token replay
+- **JWKS validation** — asymmetric algorithm allowlist (RS/ES/PS
+  256-512), HMAC excluded
+- **Algorithm allowlist enforced** — the signing key is resolved from
+  the JWKS by ``kid``; PyJWK infers the key's algorithm from the JWKS
+  ``alg``/``kty`` fields; the token header's ``alg`` must be in the
+  allowlist AND match the key type, preventing algorithm confusion
+- **Identity matching by (issuer, sub) only** — prevents account
+  takeover via email or username reuse
+- **`password_enabled=false` enforced server-side** — not just a UI
+  toggle
+- **Rate limiting** on both authorize and callback endpoints
+- **OIDC-provisioned users cannot password-login** — the password hash
+  is set to the `!oidc` sentinel, which never matches bcrypt verify
+
+#### Role mapping
+
+When `TURNSTONE_OIDC_ROLE_CLAIM` is set (e.g., `groups`), the server
+reads that claim from the ID token and maps values to Turnstone roles
+via `TURNSTONE_OIDC_ROLE_MAP`. Roles are synced on every login:
+matching claim values are added, and stale OIDC-assigned roles are
+revoked. Roles assigned manually (not by OIDC) are never touched.
+
+If no role mapping is configured, OIDC users are provisioned with the
+`builtin-viewer` role by default.
+
+#### OIDC-only mode
+
+Setting `TURNSTONE_OIDC_PASSWORD_ENABLED=false` hides the password
+form on the login page and blocks password-based login at the API
+level. The setup wizard always works regardless of this setting — the
+first admin user is created with a password before OIDC is relevant.
+API tokens and config-file tokens are unaffected by this setting.
+
+#### Known limitations
+
+- **No session revocation** — deprovisioned IdP users retain their JWT
+  until the 24-hour expiry
+- **Single IdP** — configuration supports one issuer (the database
+  schema supports multiple for future expansion)
+- **Redirect URI** — defaults to request Host header; deployments behind
+  reverse proxies should set `TURNSTONE_OIDC_REDIRECT_BASE` to the
+  externally-reachable origin to pin the redirect URI

+Settings follow a typed registry pattern: every storable setting has a
+`SettingDef` entry in `settings_registry.py` with type, default, description,
+validation constraints, and a `restart_required` flag. Unknown keys are rejected
+at the API boundary.
+
+At runtime, `ConfigStore` loads all settings from storage into an in-memory
+cache. Reads are lock-free dict lookups on an immutable snapshot. Writes acquire
+a lock, persist to storage, and swap the cache atomically.
+
+---
+
+## Precedence
+
+Settings resolution differs between entry points:
+
+| Entry point | Chain |
+|-------------|-------|
+| **Server** (`turnstone-server`, `turnstone-bridge`) | CLI flag > ConfigStore > registry default |
+| **CLI** (`turnstone`) | CLI flag > config.toml > argparse default |
+
+The server's `apply_config()` ignores config.toml sections that overlap with
+ConfigStore. A startup warning is logged for each overlapping key, directing
+users to the admin Settings API.
+
+---
+
+## Bootstrap vs ConfigStore
+
+**Bootstrap settings** are required before storage is available (database
+connection, Redis, auth secrets, server bind address). These stay in
+`config.toml` and environment variables.
+
+| Category | Section | Where |
+|----------|---------|-------|
+| API credentials | `[api]` | config.toml / env |
+| Database | `[database]` | config.toml / env |
+| Redis | `[redis]` | config.toml / env |
+| Auth | `[auth]` | config.toml / env |
+| Bridge identity | `[bridge]` | config.toml / env |
+| Console bind | `[console]` | config.toml / env |
+
+**ConfigStore settings** (~40 settings) are loaded from the database after
+storage initialization:
+
+| Section | Settings |
+|---------|----------|
+| `model` | name, temperature, max_tokens, reasoning_effort, context_window |
+| `session` | instructions, retention_days, compact_max_tokens, auto_compact_pct |
+| `tools` | timeout, truncation, agent_max_turns, skip_permissions, search, search_threshold, search_max_results |
+| `server` | workstream_idle_timeout, max_workstreams |
+| `mcp` | config_path, refresh_interval, registry_url |
+| `ratelimit` | enabled, requests_per_second, burst |
+| `health` | backend_probe_interval, backend_probe_timeout, circuit_breaker_threshold, circuit_breaker_cooldown |
+| `judge` | enabled, model, provider, base_url, api_key, confidence_threshold, max_context_ratio, timeout, read_only_tools |
+| `memory` | relevance_k, fetch_limit, max_content, nudge_cooldown, nudges |
+
+Settings are addressed by dotted key (e.g. `memory.relevance_k`). Each has a
+declared type (`int`, `float`, `str`, `bool`), optional `min_value`/`max_value`
+range, optional `choices` list, and an `is_secret` flag.
+
+---
+
+## Storage
+
+The `system_settings` table (migration 015) stores settings as JSON-encoded
+values with a composite primary key of `(key, node_id)`:
+
+| Column | Type | Description |
+|--------|------|-------------|
+| `key` | text | Dotted setting key (e.g. `model.temperature`) |
+| `value` | text | JSON-encoded value |
+| `node_id` | text | Node ID for per-node overrides (empty string = global) |
+| `is_secret` | int | 1 if the setting contains secrets |
+| `changed_by` | text | Username of last editor |
+| `created` | text | ISO timestamp |
+| `updated` | text | ISO timestamp |
+
+Per-node overrides layer on top of global settings. When `ConfigStore` loads,
+it fetches global settings first, then overlays per-node values.
+
+---
+
+## Admin API
+
+Four endpoints on the **console** server, all requiring the `admin.settings`
+permission.
+
+### `GET /v1/api/admin/settings`
+
+List all settings with their effective values, defaults, and metadata.
+
+**Response:** `200`
+
+```json
+{
+  "settings": [
+    {
+      "key": "model.temperature",
+      "value": 0.7,
+      "source": "storage",

+      "description": "Sampling temperature",
+      "section": "model",
+      "is_secret": false,

+      "updated": "2026-03-14T10:00:00",
+      "restart_required": false
+    }
+  ]
+}
+```
+
+---
+
+### `GET /v1/api/admin/settings/schema`
+
+Return the full registry catalog (all defined settings with metadata). Useful
+for building dynamic admin UIs.
+
+**Response:** `200`
+
+```json
+{
+  "schema": [
+    {
+      "key": "model.temperature",
+      "type": "float",

+      "max_value": 2.0,
+      "choices": null,
+      "restart_required": false
+    }
+  ]
+}
+```
+
+---
+
+### `PUT /v1/api/admin/settings/{key}`
+
+Update a setting. The value is validated against the registry (type coercion,
+range, choices). Secret settings (`is_secret=true`) cannot be written via the
+API -- they must be configured via config.toml or environment variables.
+
+**Path parameters:**
+
+| Parameter | Type   | Description |
+|-----------|--------|-------------|
+| `key`     | string | Dotted setting key (e.g. `model.temperature`) |
+
+**Request body:**

+  "value": 0.7,
+  "node_id": ""
+}
+```
+

+|-----------|--------|----------|---------|-------------|
+| `value`   | any    | yes      | --      | New value (type-coerced against registry) |
+| `node_id` | string | no       | `""`    | Node ID for per-node override |
+
+**Response (success):** `200`
+
+```json
+{
+  "key": "model.temperature",
+  "value": 0.7,
+  "source": "storage",
+  "type": "float",
+  "description": "Sampling temperature",

+  "is_secret": false,
+  "node_id": "",
+  "changed_by": "admin",
+  "updated": "",
+  "restart_required": false
+}
+```
+
+**Errors:**
+
+| Status | Condition |
+|--------|-----------|
+| 400    | Unknown key, invalid value, type mismatch, out of range |
+| 403    | Secret setting (must use config.toml or env) |
+
+---
+
+### `DELETE /v1/api/admin/settings/{key}`
+
+Reset a setting to its registry default by removing it from storage.
+
+**Path parameters:**
+
+| Parameter | Type   | Description |
+|-----------|--------|-------------|
+| `key`     | string | Dotted setting key |
+
+**Query parameters:**
+
+| Parameter | Type   | Required | Default | Description |
+|-----------|--------|----------|---------|-------------|
+| `node_id` | string | no       | `""`    | Node ID (empty = global) |
+
+**Response (success):** `200`
+
+```json
+{"status": "ok", "key": "model.temperature", "default": 0.5}
+```
+
+**Response (not found):** `404`
+
+```json
+{"error": "Setting 'model.temperature' has no stored value"}
+```
+
+---
+
+## Secret Settings
+
+Settings with `is_secret=True` (currently only `judge.api_key`) are blocked
+from the write API with a `403` response. This prevents accidental exposure
+through the admin UI or audit logs. Secret settings must be configured via
+`config.toml` or environment variables.
+
+The list endpoint masks secret values: stored secrets appear as `"***"`
+rather than their actual value.
+
+---
+
+## Hot Reload
+
+`ConfigStore` caches all settings in memory for fast, lock-free reads. To
+refresh the cache after external changes (e.g. direct database edits or
+cluster-wide propagation):
+
+```
+POST /v1/api/_internal/config-reload
+```
+
+This triggers `ConfigStore.reload()`, which re-reads all settings from storage
+and atomically swaps the cache. The `version` counter increments on every
+reload.
+
+**Behavior after reload:**
+
+- New workstreams pick up updated values immediately (via `session_factory`)
+- Existing sessions keep their frozen configuration (settings are captured at
+  workstream creation time, not read on every turn)
+- Settings marked `restart_required=True` need a server restart to take effect
+
+---
+
+## Migration from config.toml
+
+On startup, `warn_migrated_settings()` scans `config.toml` for keys that are
+now managed by ConfigStore. Each overlap produces a warning:
+
+```
+WARNING config.toml [model] temperature is now managed via Settings API —
+this value will be ignored. Use the admin Settings tab or
+PUT /v1/api/admin/settings/model.temperature to configure.
+```
+
+To migrate:
+
+1. Note the values from `config.toml` for sections that overlap with ConfigStore
+2. Use `PUT /v1/api/admin/settings/{key}` or the console Settings tab to set
+   each value
+3. Remove the migrated sections from `config.toml`
+4. Restart the server to verify no warnings
+
+---
+
+## SDK
+
+### Python
+
+```python
+from turnstone.sdk import TurnstoneConsole
+
+with TurnstoneConsole("http://localhost:9090", token="tok_xxx") as admin:
+    # List all settings with effective values
+    result = admin.list_settings()

+# MCP Cluster Ops
+
+An MCP server that exposes tools for executing commands across a [Turnstone](https://github.com/turnstonelabs/turnstone) cluster. Serves as a reference implementation for both MCP server patterns and Turnstone MQ client SDK usage.
+
+## How it works
+
+This server uses Turnstone's MQ client (`TurnstoneClient`) to dispatch shell commands to specific nodes via Redis. Remote agents execute the command and the raw bash output is captured directly from the `ToolResultEvent` stream — bypassing the costly "agent reads output → re-generates output as completion tokens" round-trip.
+
+Multi-node dispatches run in parallel via `asyncio.gather`, so total wall time is bounded by the slowest node rather than the sum.
+
+## Tools
+
+| Tool | Description |
+|------|-------------|
+| `list_nodes` | Discover active nodes in the cluster |
+| `run_on_node` | Execute a command on a specific node |
+| `run_on_nodes` | Execute a command on selected nodes in parallel |
+| `run_on_all_nodes` | Execute a command on ALL active nodes in parallel |
+
+## Prerequisites
+
+- A running Turnstone cluster (at least one `turnstone-server` + `turnstone-bridge`)
+- Redis accessible from wherever this MCP server runs
+- Python 3.11+
+
+## Installation
+
+```bash
+# From the turnstone repo root:
+pip install -e ./examples/mcp-cluster-ops
+
+# Or install turnstone with MQ support first, then the example:
+pip install -e ".[mq]"
+pip install -e ./examples/mcp-cluster-ops
+```
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `REDIS_HOST` | `localhost` | Redis host |
+| `REDIS_PORT` | `6379` | Redis port |
+| `REDIS_PASSWORD` | _(none)_ | Redis password (use env vars, not config files) |
+| `MCP_CLUSTER_OPS_TIMEOUT` | `120` | Default command timeout (seconds, clamped 5-3600) |
+| `MCP_CLUSTER_OPS_MAX_OUTPUT` | `8192` | Max output bytes per node (0 = unlimited) |
+| `MCP_CLUSTER_OPS_MAX_NODES` | `32` | Max concurrent node dispatches |
+| `MCP_CLUSTER_OPS_MAX_COMMAND` | `65536` | Max command string length |
+
+### Register with Turnstone
+
+**TOML** (`~/.config/turnstone/config.toml`):
+
+```toml
+[mcp.servers.cluster-ops]
+command = "mcp-cluster-ops"
+
+[mcp.servers.cluster-ops.env]
+REDIS_HOST = "redis.example.com"
+```
+
+**JSON** (via `--mcp-config`):
+
+```json
+{
+  "mcpServers": {
+    "cluster-ops": {
+      "command": "mcp-cluster-ops",
+      "env": {
+        "REDIS_HOST": "redis.example.com"
+      }
+    }
+  }
+}
+```
+
+## Usage Examples
+
+Once registered, the tools appear in any Turnstone session. The model can:
+
+```
+> Check disk usage across the cluster
+
+[calls list_nodes → discovers node-1, node-2, node-3]
+[calls run_on_all_nodes with "df -h /"]
+
+node-1: /dev/sda1  500G  320G  180G  64%  /
+node-2: /dev/sda1  500G  410G   90G  82%  /
+node-3: /dev/sda1  1.0T  200G  800G  20%  /
+```
+
+## Why MQ client instead of HTTP SDK?
+
+The HTTP SDK (`TurnstoneServer`) talks to a single server instance. The MQ client (`TurnstoneClient`) routes through Redis with `target_node` support, which is the entire point of cross-node cluster operations.
+
+## Security Considerations
+
+**This MCP server grants the calling agent shell access to cluster nodes.**
+
+- Commands are executed with `auto_approve=True` and the privileges of the
+  Turnstone server process on the target node.
+- Command output (which may contain secrets, credentials, or sensitive data)
+  is returned through the MCP tool result and becomes part of the LLM context.
+- The security boundary is at the MCP host layer -- use Turnstone's tool
+  policy system to restrict which agents can invoke these tools.
+- Set `REDIS_PASSWORD` via your environment or a secrets manager -- avoid
+  hardcoding passwords in config files.
+
+## Development
+
+```bash
+cd examples/mcp-cluster-ops
+
+# Run tests
+pip install -e ".[test]"
+pytest
+
+# Lint
+pip install -e ".[dev]"
+ruff check mcp_cluster_ops/
+mypy --strict mcp_cluster_ops/

+-----------------
+Remote agents are told to reply with only "ok" or "failed" — the raw bash
+output is captured directly from the ToolResultEvent that already flows
+through Redis, bypassing the costly "agent reads output then re-generates
+output as completion tokens" round-trip.
