chore: bump version to 1.0.2

* fix: improve web_fetch reliability — strip scripts, dynamic truncation, more tokens

- strip_html() now removes <script>, <style>, <template>, <noscript>
  element content instead of just their tags
- Truncation budget scales with context window (75% in chars, 50k floor)
  and takes from the beginning only instead of head+tail splice
- max_tokens bumped from 2000 to 8192 so thinking models don't starve
  the visible extraction answer
- reasoning_effort="low" on summarization call to avoid wasting tokens
- Empty responses and empty extractions now report as tool errors

* refactor: extract _utility_completion to fix reasoning_effort duplication

Callers previously had to pass reasoning_effort both as a direct keyword
(for commercial providers) and via _provider_extra_params (for local
model servers).  This duplication was easy to get wrong — web_fetch was
already missing the direct keyword.

_utility_completion threads it through both paths from a single call,
used by title generation, compaction, and web_fetch extraction.

* fix: disable thinking when max_tokens too small, cap extraction at 500k

_reasoning_params now returns empty dict when max_tokens can't fit a
thinking budget (e.g. title gen with max_tokens=200).  Previously
produced budget_tokens >= max_tokens which is an API error on
manual-thinking Anthropic models.

Also caps web_fetch content truncation at 500k chars — the dynamic
context-window calc was producing 3M chars on 1M-context models.

* fix: clamp utility max_tokens to model output limit, add strip_html tests

_utility_completion now clamps max_tokens to the model's advertised
max_output_tokens so small/local models don't reject 8192-token
requests.

Adds 8 tests for invisible element stripping (script, style, template,
noscript) including multiline, case-insensitive, and attribute cases.

* fix: mock get_capabilities in title retry tests for _utility_completion

_utility_completion calls _get_capabilities to clamp max_tokens.  The
existing title tests mocked _provider as a bare MagicMock, so
caps.max_output_tokens was a truthy MagicMock instead of an int.  Set
get_capabilities to return a real ModelCapabilities instance.

 ## What it does
 
-Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports. It runs as:
+Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports.
 
 - **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, 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, OIDC SSO (Okta, Azure AD, Google, Keycloak), tool policies, skills (reusable behavioral profiles with security scanning), 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).

 ## Quickstart
 
-### Interactive (terminal)
-
 ```bash
 pip install turnstone
+
+# Terminal REPL
 turnstone --base-url http://localhost:8000/v1
-```
 
-### Interactive (browser)
-
-```bash
+# Browser UI
 turnstone-server --port 8080 --base-url http://localhost:8000/v1
-```
 
-### Queue-driven (programmatic)
-
-```bash
-pip install turnstone[mq]
-turnstone-bridge --server-url http://localhost:8080 --redis-host localhost
-```
-
-```python
-from turnstone.mq import TurnstoneClient
-
-with TurnstoneClient() as client:
-    # Generic — any available node picks it up
-    result = client.send_and_wait("Analyze the error logs", auto_approve=True)
-    print(result.content)
-
-    # Directed — must run on a specific server
-    result = client.send_and_wait(
-        "Check disk I/O on this server",
-        target_node="server-12",
-        auto_approve=True,
-    )
-```
-
-### Cluster dashboard
-
-```bash
+# Cluster dashboard
 pip install turnstone[console]
-turnstone-console --redis-host localhost --port 8090
+turnstone-console --port 8090
 ```
 
-Then open `http://localhost:8090` for the cluster-wide dashboard. Create workstreams from the console and interact with any node's server UI through the built-in reverse proxy — no direct server port access required.
-
 ### Docker
 
 ```bash
 cp .env.example .env  # edit LLM_BASE_URL, OPENAI_API_KEY, etc.
-docker compose up     # starts redis + server + bridge + console (SQLite)
+docker compose --profile production up
 ```
 
-For production with PostgreSQL:
+See [QUICKSTART.md](QUICKSTART.md) for the bootstrap wizard and [docs/docker.md](docs/docker.md) for Docker configuration and profiles.
 
-```bash
-# Requires POSTGRES_PASSWORD and DB_BACKEND=postgresql in .env (or exported)
-docker compose --profile production up  # adds PostgreSQL, uses it as database
+### Programmatic (SDK)
+
+```python
+from turnstone.sdk import TurnstoneServer
+
+with TurnstoneServer("http://localhost:8080", token="tok_xxx") as client:
+    ws = client.create_workstream(name="demo")
+    result = client.send_and_wait("Analyze the error logs", ws.ws_id, auto_approve=True)
+    print(result.content)
 ```
 
-Console dashboard at http://localhost:8090. See [docs/docker.md](docs/docker.md) for configuration, scaling, and profiles.
-
-### Simulator
-
-Test the multi-node stack at scale without an LLM backend:
-
-```bash
-docker compose --profile sim up redis console sim
-```
-
-Or standalone:
-
-```bash
-pip install turnstone[sim]
-turnstone-sim --nodes 100 --scenario steady --duration 60 --mps 10
-```
-

-
-### 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
-- **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 (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) — 36 pattern-based rules classify tool calls by severity. Catches destructive commands (`rm -rf /`, `DROP TABLE`), privilege escalation (`sudo`), credential access, supply chain risks, browser data export, cloud infrastructure mutations, 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`).
-
-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.
-
-Tool execution results are evaluated by an output guard before entering the conversation — detecting prompt injection payloads in fetched content, credential leakage in command output, and encoded payloads. Detected credentials are automatically redacted.
-
-See [docs/judge.md](docs/judge.md) for the full guide.
-
-## Multi-node routing
-
-Each Turnstone server runs a bridge process. Bridges share a Redis instance for coordination:
-
-| Redis Key | Purpose |
-|-----------|---------|
-| `turnstone:inbound` | Shared work queue — generic tasks, any node |
-| `turnstone:inbound:{node_id}` | Per-node queue — directed tasks |
-| `turnstone:ws:{ws_id}` | Workstream ownership — auto-routes follow-ups |
-| `turnstone:node:{node_id}` | Node heartbeat + metadata for discovery |
-| `turnstone:events:{ws_id}` | Per-workstream event pub/sub |
-| `turnstone:events:global` | Global event pub/sub |
-| `turnstone:events:cluster` | Cluster-wide state changes (for turnstone-console) |
-
-**Routing rules:**
-1. Message has `target_node` → routes to that node's queue
-2. Message has `ws_id` → looks up owner, routes to owning node
-3. Neither → shared queue, next available bridge picks it up
-
-Bridges BLPOP from their per-node queue (priority) then the shared queue. Directed work always takes precedence.
-
 ## Tools
 
-15 built-in tools, 2 agent tools, plus external tools via MCP:
+Built-in tools for shell, files, search, web, memory, notifications, and autonomous sub-agents — plus external tools via [MCP](https://modelcontextprotocol.io/) with native deferred loading. See [docs/tools.md](docs/tools.md) for the full reference and [docs/mcp.md](docs/mcp.md) for MCP configuration.
 
-| Tool | Description | Auto-approved |
-|------|-------------|:---:|
-| `bash` | Execute shell commands | |
-| `read_file` | Read file contents (text or images with vision models) | yes |
-| `write_file` | Write/create files | |
-| `edit_file` | Fuzzy-match file editing | |
-| `search` | Search files by name/content | yes |
-| `math` | Sandboxed Python evaluation | |
-| `man` | Read man pages | yes |
-| `web_fetch` | Fetch URL content | |
-| `web_search` | Web search (provider-native or Tavily) | |
-| `memory` | Structured persistent memory (save/search/delete/list) | yes |
-| `recall` | Search conversation history | yes |
-| `notify` | Send notifications to linked channels | yes |
-| `watch` | Periodic command polling with conditions | |
-| `task` | Spawn autonomous sub-agent | |
-| `plan` | Explore codebase, write .plan.md | |
-| `mcp__*` | External tools from MCP servers | |
+## Architecture
 
-When the total tool count exceeds a configurable threshold (default 20), MCP tools are automatically deferred using native `defer_loading` on Anthropic and OpenAI APIs, or a transparent client-side BM25 search for local models. The LLM discovers deferred tools on demand via a `tool_search` capability — no configuration needed beyond `--tool-search auto` (the default).
+**Single-node**: Client → Server (direct HTTP + SSE). No external dependencies beyond the database.
 
-### MCP Tool Servers
+**Multi-node**: Client → Console (hash ring routing proxy) → Server nodes. The console maintains a 65536-entry bucket cache for O(1) workstream routing. A rebalancer daemon redistributes buckets when nodes join or leave.
 
-Turnstone supports the [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) for connecting external tool servers. MCP tools are discovered at startup, converted to OpenAI function-calling format, and merged with built-in tools. Each MCP tool is prefixed with `mcp__{server}__{tool}` to avoid name collisions. Tool lists stay fresh via push notifications (`tools.listChanged`), periodic polling for servers without push, and manual `/mcp refresh`.
+| Component | Purpose |
+|-----------|---------|
+| `turnstone` | Terminal CLI (REPL) |
+| `turnstone-server` | Web UI + REST API + SSE events |
+| `turnstone-console` | Cluster dashboard + routing proxy + admin panel |
+| `turnstone-channel` | Channel gateway (Discord, with adapters for Slack/Teams planned) |
+| `turnstone-admin` | User/token management CLI |
+| `turnstone-eval` | Eval harness for prompt/tool optimization |
+| `turnstone-bootstrap` | LLM-guided setup wizard |

-Or use a standard MCP JSON config file:
+## Documentation
 
-```bash
-turnstone --mcp-config ~/.config/turnstone/mcp.json
-turnstone-server --mcp-config ~/.config/turnstone/mcp.json
-```
-
-Use `/mcp` in the REPL to list connected tools, `/mcp refresh` to re-fetch tool lists from servers. MCP tools require user approval by default (overridden by `--skip-permissions` or UI auto-approve).
-
-### Multi-Model and Multi-Provider Support
-
-Turnstone supports multiple model backends per server instance, including different LLM providers. `ChatSession` delegates all API communication to pluggable `LLMProvider` adapters — the internal message format stays OpenAI-like, and each provider translates at the API boundary. Define named models in `config.toml` and select per-workstream or switch mid-session with `/model <alias>`.
-
-```toml
-[models.local]
-base_url = "http://localhost:8000/v1"
-model = "qwen3-32b"
-# provider defaults to "openai" (works with vLLM, llama.cpp, etc.)
-
-[models.claude]
-provider = "anthropic"
-api_key = "sk-ant-..."
-model = "claude-opus-4-6"
-context_window = 200000
-
-[models.openai]
-base_url = "https://api.openai.com/v1"
-api_key = "sk-..."
-model = "gpt-5"
-context_window = 400000
-
-[model]
-default = "local"              # which model to use by default
-fallback = ["claude", "openai"]  # try these if the primary is unreachable
-agent_model = "claude"         # optional: separate model for plan/task sub-agents
-```
-
-Supported providers: `"openai"` (default -- OpenAI, vLLM, llama.cpp, any OpenAI-compatible API) and `"anthropic"` (Anthropic Messages API, requires `pip install turnstone[anthropic]`).
-
-Use `/model` to show available models, `/model claude` to switch. Workstreams created via the API accept an optional `model` parameter.
-
-## Configuration

-## Workstreams
-
-Parallel independent conversations, each with its own session and state:
-
-| Symbol | State | Meaning |
-|--------|-------|---------|
-| `·` | idle | Waiting for input |
-| `◌` | thinking | Model is generating |
-| `▸` | running | Tool execution in progress |
-| `◆` | attention | Waiting for approval |
-| `✖` | error | Something went wrong |
-
-Idle workstreams are automatically cleaned up after 2 hours (configurable). In multi-node deployments, workstream ownership is tracked in Redis — follow-up messages auto-route to the owning node.
-
-## Monitoring
-
-`/metrics` endpoint exposes Prometheus-format metrics:
-
-- `turnstone_tokens_total{direction}` — prompt/completion token counters
-- `turnstone_tool_calls_total{tool}` — per-tool invocation counts
-- `turnstone_workstream_context_ratio{ws_id}` — per-workstream context utilization
-- `turnstone_http_request_duration_seconds` — request latency histogram
-- `turnstone_workstreams_by_state{state}` — workstream state gauges
-- `turnstone_sse_connections_active` — current open SSE connections
-- `turnstone_ratelimit_rejected_total` — requests rejected by rate limiter
-- `turnstone_backend_up` — LLM backend reachability (0/1)
-- `turnstone_circuit_state` — circuit breaker state (0=closed, 1=open, 2=half_open)
-- `turnstone_workstreams_evicted_total` — workstreams auto-evicted at capacity
-- `turnstone_judge_verdicts_total{tier,risk_level}` — intent validation verdicts by tier and risk
-- `turnstone_judge_llm_latency_seconds` — LLM judge evaluation latency histogram
-- `turnstone_judge_enabled` — whether the intent validation judge is active (0/1)
-
-Per-workstream metrics are labeled by `ws_id` (bounded by `[server].max_workstreams`).
-
-### Health & Rate Limiting
-
-**Health degradation.** A background `BackendHealthMonitor` probes the LLM backend every `backend_probe_interval` seconds. When the backend is unreachable, `/health` reports `"status": "degraded"` (HTTP 200) and the `turnstone_backend_up` gauge drops to 0.
-
-**Circuit breaker.** After `circuit_breaker_threshold` consecutive probe failures the circuit opens (CLOSED -> OPEN). While open, `ChatSession._create_stream_with_retry` skips the backend entirely and returns an error. After `circuit_breaker_cooldown` seconds the circuit enters HALF_OPEN, allowing a single probe. A successful probe closes the circuit; a failure re-opens it.
-
-**Per-IP rate limiting.** When `[ratelimit].enabled` is true, each client IP is tracked with a token-bucket limiter (`requests_per_second` / `burst`). Rate limiting is applied in `do_GET`/`do_POST` after authentication but before route dispatch. `/health` and `/metrics` are exempt. Requests that exceed the limit receive HTTP 429 with a `Retry-After` header.
-
-**Workstream eviction.** When `WorkstreamManager.create()` would exceed `max_workstreams`, the oldest IDLE workstream is automatically evicted and the `turnstone_workstreams_evicted_total` counter is incremented. Configure via `[server].max_workstreams` (default 50).

-
-**Approval flow:** When a per-WS SSE thread receives an `approve_request`, it checks
-the workstream's `auto_approve_tools` set. If all requested tools are in the set, the
-bridge auto-approves via `POST /v1/api/approve`. Otherwise, it publishes an
-`ApprovalRequestEvent` to the outbound channel with a `request_id`, then blocks on
-`BLPOP` of a Redis response queue (`turnstone:resp:{request_id}`) until the client pushes
-a response or the approval timeout (default 3600s / 1 hour) expires.
-
-**Cancellation:** The `CancelMessage` (type `"cancel"`) is a routed inbound message.
-The bridge dispatches it to `POST /v1/api/cancel` on the server owning the workstream,
-which sets the cooperative cancel flag and unblocks any pending approval/plan waits.
-
-**Completion detection:** The bridge tracks which `correlation_id` maps to which
-`ws_id` for active sends. The server accumulates content tokens in the WebUI and
-piggybacks the full response text onto the `ws_state → idle` global SSE event.
-When the bridge receives this event, it emits a synthetic `TurnCompleteEvent`
-carrying the correlation ID and the server-provided `content`. This lets downstream
-consumers (e.g. the Discord bot) recover the full response when individual
-`ContentEvent`s were missed, and serves as the primary delivery path for
-bidirectional notification DM forwarding.
-
-**Multi-node routing:** Each bridge retrieves its `node_id` from the server's
-`/health` endpoint on startup (with exponential backoff retry). The server
-generates the `node_id` (`{hostname}_{4hex}`) and is the sole authority for
-node identity. The bridge BLPOPs
-from both `turnstone:inbound:{node_id}` (directed, priority) and `turnstone:inbound` (shared).
-Messages with `target_node` set are pushed to the target's per-node queue. Messages
-for existing workstreams are auto-routed via `turnstone:ws:{ws_id}` ownership keys in Redis.
-If a bridge picks up a shared-queue message for a workstream owned by another node, it
-re-routes to that node's queue (1 extra hop). Bridges publish heartbeats to
-`turnstone:node:{node_id}` with configurable TTL for node discovery.
-On startup, `_recover_workstreams` re-registers ownership of existing
-workstreams and publishes `WorkstreamCreatedEvent` to the cluster channel
-so the console collector picks them up immediately.

+# Consistent Hash Ring — Reference Design
+
+**Status**: Reference (not currently in the hot path)
+**Date**: 2026-03-30
+
+## Overview
+
+This document describes a consistent hash ring algorithm evaluated during
+the design of the direct HTTP transport routing system. The current
+implementation uses weight-proportional bucket assignment with a
+donor/recipient rebalancing algorithm (see `direct-http-transport.md`).
+The consistent hash ring is documented here as a reference for future
+scalability work — if the cluster grows beyond the point where the
+weight-proportional approach is sufficient, the ring provides a
+proven alternative with stronger stability guarantees.
+
+## When to consider the ring approach
+
+The current weight-proportional seeding + donor/recipient rebalancer works
+well when:
+- Cluster size is moderate (< 50 nodes)
+- Nodes join/leave infrequently
+- The rebalancer runs centrally (in the console)
+
+The consistent hash ring becomes advantageous when:
+- Cluster size grows large (50+ nodes) and frequent membership changes
+  cause the donor/recipient algorithm to churn
+- Decentralized routing is needed (each node computes the ring locally,
+  no central console required)
+- Cross-language determinism is important (multiple implementations must
+  agree on the same assignment without sharing state)
+
+## Algorithm
+
+### Hash function: FNV-1a (32-bit)
+
+```python
+def fnv1a_32(data: bytes) -> int:
+    """FNV-1a 32-bit hash.
+
+    Basis: 0x811C9DC5, Prime: 0x01000193.
+    XOR each byte, then multiply by prime (masked to 32 bits).
+    """
+    h = 0x811C9DC5
+    for b in data:
+        h ^= b
+        h = (h * 0x01000193) & 0xFFFFFFFF
+    return h
+```
+
+Known test vectors:
+- `fnv1a_32(b"")` = `0x811C9DC5` (basis value)
+- `fnv1a_32(b"foobar")` = `0xBF9CF968`
+
+Cross-language implementations:
+- **Python**: loop above (no dependencies)
+- **Go**: same algorithm with `uint32` arithmetic
+- **TypeScript**: same algorithm with `>>> 0` for unsigned 32-bit
+
+### Virtual nodes
+
+Each physical node with weight `w` gets `w * 150` virtual positions on a
+16-bit ring (65536 positions). Virtual node `i` of physical node `N` is
+placed at:
+
+```
+position = fnv1a_32(f"{N.node_id}:{i}".encode()) % 65536
+```
+
+With 150 vnodes per unit weight:
+- 2 equal-weight nodes: ~50/50 split (measured: 38-62% range due to
+  hash variance, stddev ~3% with large vnode counts)
+- 3 nodes at weights 2:1:1: ~50/25/25 (within 10% tolerance)
+
+### Lookup
+
+```python
+def owner(bucket: int) -> str:
+    """O(log n) bisect-right walk to find the next virtual node clockwise."""
+    idx = bisect_right(positions, bucket)
+    if idx >= len(positions):
+        idx = 0  # wrap around
+    return vnode_map[positions[idx]]
+```
+
+### Stability properties
+
+The consistent hash ring guarantees:
+- **Node addition**: adding a node moves at most `1/N` of buckets (where N
+  is the new node count). Other nodes' buckets are unaffected.
+- **Node removal**: only the removed node's buckets are reassigned. Buckets
+  owned by surviving nodes don't move.
+- **Determinism**: same membership list always produces the same ring.
+  No coordination needed between processes.
+
+### Full assignment precomputation
+
+```python
+def assignments() -> list[tuple[int, str]]:
+    """Compute all 65536 bucket-to-node mappings."""
+    return [(b, owner(b)) for b in range(65536)]
+```
+
+This produces a complete assignment table that can be loaded into a flat
+array for O(1) request-time lookup. The ring itself is never consulted
+on the hot path.
+
+## Data structures
+
+```python
+@dataclass(frozen=True, slots=True)
+class RingNode:
+    node_id: str
+    url: str
+    weight: int = 1
+
+class HashRing:
+    """Immutable consistent hash ring. Thread-safe (no mutable state)."""
+
+    def __init__(self, nodes: Sequence[RingNode], vnodes_per_unit: int = 150):
+        # Validate no duplicate node_ids
+        # Build sorted array of (position, node_id) tuples
+        # positions[i] = fnv1a_32(f"{node_id}:{i}".encode()) % RING_SIZE
+
+    def owner(self, bucket: int) -> RingNode | None:
+        # bisect_right + wrap
+
+    @property
+    def version(self) -> int:
+        # Deterministic hash of membership: fnv1a_32 of sorted node_id:weight pairs
+
+    def assignments(self) -> list[tuple[int, str]]:
+        # Precompute all 65536 bucket assignments
+```
+
+## Comparison with current approach
+
+| Aspect | Weight-proportional (current) | Consistent hash ring |
+|--------|------------------------------|---------------------|
+| Seeding | Exact weight split, deterministic | Hash-based, ~3% variance |
+| Node addition | Donor/recipient moves only excess | Ring moves ~1/N buckets |
+| Node removal | Dead buckets → most underloaded | Ring redistributes to clockwise neighbors |
+| Cross-node churn | Zero (only donor→recipient) | Zero (ring stability guarantee) |
+| Decentralized | No (needs central rebalancer) | Yes (each node computes locally) |
+| Complexity | Simple weight arithmetic | Virtual node construction + bisect |
+
+## Test vectors
+
+For cross-language implementation validation:
+
+```json
+{
+  "fnv1a_32": [
+    {"input": "", "output": 2166136261},

+# Release Process
+
+Turnstone uses two parallel release tracks published from a single PyPI package.
+
+## Release Tracks
+
+| Track | Versions | Branch | Docker tags | PyPI install |
+|-------|----------|--------|-------------|--------------|
+| **Stable** | `1.0.0`, `1.0.1` | `stable/1.0` | `:1.0.1`, `:1.0`, `:stable`, `:latest` | `pip install turnstone` |
+| **Experimental** | `1.1.0a1`, `1.1.0a2` | `main` | `:1.1.0a1`, `:experimental` | `pip install turnstone --pre` |
+
+- **Stable** receives bugfixes only. Production-grade.
+- **Experimental** receives new features. May be rough around the edges.
+- When experimental matures, it is promoted to stable. The previous stable branch stops receiving patches.
+
+## Version Scheme
+
+[PEP 440](https://peps.python.org/pep-0440/) pre-release suffixes on a single package:
+
+- `1.0.0` — stable release
+- `1.1.0a1` — alpha (experimental)
+- `1.1.0b1` — beta (experimental, more stable)
+- `1.1.0rc1` — release candidate (experimental, nearly stable)
+- `1.1.0` — promoted to stable
+
+## Releasing an Experimental Version (from main)
+
+```bash
+scripts/release.sh 1.1.0a2 --push
+```
+
+This bumps `pyproject.toml` + `turnstone/__init__.py`, regenerates `uv.lock`, commits, tags `v1.1.0a2`, and pushes. CI runs, then publish + Docker workflows fire automatically.
+
+## Releasing a Stable Patch (from stable/X.Y)
+
+```bash
+git checkout stable/1.0
+git cherry-pick <commit-hash>    # bugfix from main
+scripts/release.sh 1.0.2 --push
+```
+
+## Promoting Experimental to Stable
+
+When `main` is ready for a stable release:
+
+```bash
+# 1. Tag the stable release on main
+scripts/release.sh 1.1.0 --push
+
+# 2. Create the stable maintenance branch from that tag
+git branch stable/1.1 v1.1.0
+git push origin stable/1.1
+
+# 3. Start the next experimental cycle on main
+scripts/release.sh 1.2.0a1 --push
+```
+
+The previous `stable/1.0` branch stops receiving patches at this point.
+
+## CI/CD Pipeline
+
+All releases are gated on CI success:
+
+1. `git push` with `v*` tag triggers **CI** (lint, typecheck, test, test-postgres, lock-check, security audit)
+2. On CI success, **Publish to PyPI** fires via `workflow_run`
+3. On CI success, **Publish Docker Image** fires via `workflow_run`
+
+Pre-release tags (`a`, `b`, `rc` suffixes) produce:
+- PyPI: pre-release version (not installed by default)
+- GitHub Release: marked as pre-release
+- Docker: `:experimental` alias + exact version tag
+
+Stable tags produce:
+- PyPI: stable version (default `pip install`)
+- GitHub Release: full release
+- Docker: `:stable`, `:latest`, `:X.Y`, `:X.Y.Z` tags
+
+## Dependency Updates
+
+Renovate targets `main` (experimental) only. Stable branches receive manual dependency updates via cherry-pick when security-relevant.

-# Cluster Simulator
-
-The simulator (`turnstone-sim`) creates lightweight simulated nodes that talk to a real Redis instance using the standard turnstone protocol. External observers — `TurnstoneClient`, `turnstone-console`, real bridges — see identical behavior. No LLM backend is needed.
-
-## Quick Start
-
-```bash
-pip install turnstone[sim]
-
-# 10 nodes, steady load, 60 seconds
-turnstone-sim --nodes 10 --scenario steady --duration 60 --mps 5
-
-# 100 nodes via Docker
-docker compose --profile sim up redis console sim
-```
-
-## How It Works
-
-Each simulated node is an asyncio coroutine (not a thread or process), so 1000 nodes run efficiently on a single event loop. The simulator:
-
-1. Registers nodes via Redis heartbeats (same keys as real bridges)
-2. Accepts messages from per-node and shared inbound queues
-3. Simulates LLM responses with configurable latency and token generation
-4. Simulates tool execution with configurable latency and failure rates
-5. Publishes real protocol events (`ContentEvent`, `StateChangeEvent`, `TurnCompleteEvent`, etc.)
-6. Reports latency, throughput, and utilization metrics at completion
-
-```
-TurnstoneClient → Redis Queue → SimNode → Redis Pub/Sub → TurnstoneClient
-                                  ↓

-| `burst` | Push `--burst-size` messages instantly, then wait for completion |
-| `node_failure` | Steady load + periodically kill nodes to test redistribution |
-| `directed` | Send messages to specific nodes via `target_node` routing |

+An MCP server that exposes tools for executing commands across a Turnstone cluster. Serves as a reference implementation for both MCP server patterns and Turnstone 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.
+This server uses the Turnstone console SDK (`TurnstoneConsole`) for node discovery and routing, and `TurnstoneServer` for per-node SSE streaming. The dispatch flow for each command is:
+
+1. **Route** — `TurnstoneConsole.route_create_workstream(target_node=..., auto_approve=True)` creates a workstream pinned to the target node via the console's hash-ring routing proxy, returning `ws_id` and `node_url`.
+2. **Execute** — `TurnstoneServer(node_url, token=...)` connects directly to the node's SSE stream using the same `TURNSTONE_API_TOKEN`. `send_and_wait(prompt, ws_id)` runs the command and the raw bash output is captured from the `ToolResultEvent` — bypassing the costly "agent reads output then re-generates output as completion tokens" round-trip.
+3. **Cleanup** — `TurnstoneConsole.route_close(ws_id)` closes the workstream.
