chore: bump version to 1.2.0a3

* feat: reconcile judge admin rule UX with edit, disable, and reset actions

Replace the misleading "Customize" button on built-in rules with a
logically consistent 4-state action model: pure built-in (Disable/Edit),
overridden built-in (Disable/Edit/Reset), disabled built-in
(Enable/Edit/Reset), and custom rule (Enable-Disable/Edit/Delete).

Add edit modals for both heuristic rules and output guard patterns,
reusing the existing create modal form structure. Introduce amber
"Reset" button styling to visually distinguish reversible resets from
permanent deletes. Fix source badge redundancy (disabled built-ins now
show grey "built-in" in SOURCE, red "disabled" in STATUS only). Add
aria-labels and role="listitem" for screen reader support.

* fix: preserve built-in pattern_flags and priority on override

Derive pattern_flags from compiled regex for built-in output guard
patterns in the list API so IGNORECASE and other flags survive the
disable/edit/override round-trip. Carry priority through edit modals
via hidden fields so built-in evaluation order is preserved.

 Multi-node AI orchestration platform. Deploy tool-using AI agents across a cluster of servers with direct HTTP routing, interactive interfaces, and enterprise governance.
 
-> **Beta — Use at your own risk.** APIs, configuration formats, and database schemas may change between versions without migration paths.

 Named after the [Ruddy Turnstone](https://en.wikipedia.org/wiki/Ruddy_turnstone) (*Arenaria interpres*) — a shorebird that flips stones to discover what's hiding underneath.
 
+### Release Tracks
+
+| Track | Install | Docker | Description |
+|-------|---------|--------|-------------|
+| **Stable** | `pip install turnstone` | `ghcr.io/turnstonelabs/turnstone:stable` | Production-grade. Bugfixes only. |
+| **Experimental** | `pip install turnstone --pre` | `ghcr.io/turnstonelabs/turnstone:experimental` | New features. May have rough edges. |
+
+See [docs/releasing.md](docs/releasing.md) for the full release process.
+
 ## What it does
 
 Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports.

+# Release Process
+
+Turnstone uses two parallel release tracks published from a single PyPI package.
+
+## Release Tracks
+
+| Track | Versions | Branch | Docker tags | PyPI install |
+|-------|----------|--------|-------------|--------------|
+| **Stable** | `1.1.0`, `1.1.1` | `stable/1.1` | `:1.1.0`, `:1.1`, `:stable`, `:latest` | `pip install turnstone` |
+| **Experimental** | `1.2.0a1`, `1.2.0a2` | `main` | `:1.2.0a1`, `: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.

+### Token Types
 
-The config-file token (`TURNSTONE_AUTH_TOKEN`) still works as a simple Bearer token for environments that do not use the user/JWT system. When the server receives a non-JWT Bearer token, it falls back to the legacy token check.
+The SDK accepts any Bearer token — JWTs (from `ServiceTokenManager` or login) and API tokens (`ts_` prefix) are both supported. Use `token_factory` for auto-rotating JWTs or a static `token` for API tokens.

+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 SDK client (`TurnstoneServer`) to dispatch shell commands to specific nodes via HTTP. 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.

 - NEVER echo API keys or passwords back to the user in your text responses.
 - ALWAYS use `generate_secret` for passwords and secrets — never invent them.
 - When writing files, use `write_file` — the user will see a preview and confirm.
+- If `compose.yaml` is missing, call `write_compose` before anything else. \
+The compose file uses pre-built images from ghcr.io — no local Docker build is needed.
 - If an existing .env is detected, summarize what's configured and ask what to change.
-- For cluster mode, the compose.yaml has a fixed 10-node fleet — no override needed.
-- For cluster + DuckDuckGo Search, use `--profile ddgCluster` instead of `--profile cluster`. \
-Set `MCP_CONFIG=/etc/turnstone/mcp-ddg.json` in `.env`. No API key needed. \
-The DuckDuckGo MCP sidecar starts automatically and all cluster nodes connect to it. \
-Note: the MCP SDK's DNS rebinding protection must be disabled for Docker-internal networking \
-(the compose.yaml handles this), and the server must bind to 0.0.0.0 (not 127.0.0.1) to be \
-reachable from other containers.
 - The `DATABASE_URL` for docker compose internal networking uses the hostname `postgres` \
-(e.g., `postgresql://turnstone:<password>@postgres:5432/turnstone`).
+(e.g., `postgresql+psycopg://turnstone:<password>@postgres:5432/turnstone`).
 - For local LLM backends (vLLM, llama.cpp, Ollama, etc.), set `OPENAI_API_KEY=dummy` in the \
 .env file — local servers typically don't require authentication. The `LLM_BASE_URL` should \
 use `host.docker.internal` to reach the host machine from inside Docker \
