-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)
-- **Governance & compliance** — role-based access control, tool policies, usage tracking, and append-only audit logs
+- **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).

+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. See [docs/governance.md](docs/governance.md) for setup and [docs/settings.md](docs/settings.md) for the settings reference.
+
+### 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.

+## 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).

   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 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.

+# 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.

+# 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.
+
+---
+

+```
+

+
+## Storage
+
+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.

+# System Settings
+
+> See also: [Settings Architecture diagram](diagrams/png/24-settings-architecture.png)
+
+The system settings feature provides database-backed configuration for server
+nodes. Settings are stored in the `system_settings` table and managed through
+the admin API or console Settings tab. This replaces `config.toml` for
+non-bootstrap settings on server entry points, while the CLI continues to read
+`config.toml` directly.
+
+## Overview
+
+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 |
+| `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",
+      "type": "float",
+      "description": "Sampling temperature",
+      "section": "model",
+      "is_secret": false,
+      "node_id": "",
+      "changed_by": "admin",
+      "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",
+      "default": 0.5,
+      "description": "Sampling temperature",
+      "section": "model",
+      "is_secret": false,
+      "min_value": 0.0,
+      "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:**
+
+```json
+{
+  "value": 0.7,
+  "node_id": ""
+}
+```
+
+| Field     | Type   | Required | Default | Description |
+|-----------|--------|----------|---------|-------------|
+| `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",

+| `key`     | string | Dotted setting key |
+
+**Query parameters:**
+
+| Parameter | Type   | Required | Default | Description |

+```
+
+**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
+
+---

+# 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

+pip install -e ".[test]"
+pytest

+After the stack is running, ~40 runtime settings (model, temperature, max_tokens, \
+reasoning_effort, tool timeout, rate limiting, health probes, judge config, memory \
+config, etc.) are configurable via the admin Settings tab in the console — no \
