chore: bump version to 1.2.2

fix: universal tool_call/tool_result orphan detection for OpenAI-comp… (#346 )
* fix: universal tool_call/tool_result orphan detection for OpenAI-compat providers The Anthropic provider had orphan detection for mismatched tool_call ↔ tool_result pairs, but OpenAI-compatible providers (Chat Completions, Google, Responses API) had none. When an Anthropic model runs behind an OpenAI-compat API (e.g. Azure) or cancellation creates orphans, the API rejects the malformed request. - Rewrite sanitize_messages() with orphan detection: synthesize error tool results for unmatched tool_calls, drop tool results with no matching tool_call, fill empty tool_call IDs with positional remap - Call sanitize_messages() from Responses API _convert_messages() * fix: address review feedback on orphan detection - Track answered IDs per-turn (local_answered) instead of scanning all of out, preventing false matches from reused IDs across turns - Drop empty-ID tool results that have no remap entry instead of passing them through with invalid empty tool_call_id - Increment empty_result_idx for every empty result, not just remapped - Remove dead result_ids peek-ahead code - Add test for repeated tool_call IDs across turns

-# Changelog
-
-All notable changes to turnstone are documented here.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
-and this project adheres to [PEP 440](https://peps.python.org/pep-0440/) for
-version numbers (`X.Y.Z`, with `X.Y.ZaN` / `bN` / `rcN` for pre-releases).
-
-Three release tracks are maintained:
-
- **`stable/1.0`** — patch-only (`v1.0.x`)
- **`stable/1.3`** — patch-only (`v1.3.x`)
- **`stable/1.4`** — patch-only (`v1.4.x`)
- **`main`** — experimental (`v1.5.0aN`)
-
-## [Unreleased]
-
-## [1.4.0]
-
-User-visible additions: a full attachment system (images + text documents,
-including pre-creation uploads), a unified dashboard composer, a Slack
-channel adapter, per-call plan/task model selection with an admin UI, and
-provider capability passthrough.
-
-This release introduces two forward-only schema migrations
-(`037_workstream_attachments`, `038_workstream_attachments_reserved_at`)
-that the server applies automatically on first startup against an
-existing 1.3.x database.  Both are additive; no data loss.  See
-**Database migrations** below for details.
-
-### Added
-
- **Workstream attachments** — images (png/jpeg/gif/webp, 4 MiB cap) and
-  text documents (any `text/*` MIME, allowlisted application MIMEs, or
-  known text extensions; 512 KiB cap; UTF-8 enforced).  Magic-byte image
-  sniffing on upload; per-(ws, user) pending cap of 10.  Three-state
-  lifecycle (`pending → reserved → consumed`) with reservation tokens
-  threaded through `/v1/api/send` so queued multimodal turns can't lose
-  files to overlapping sends.  Provider-side translation: Anthropic
-  emits native document blocks; OpenAI Chat Completions inlines them as
-  escaped `<document>` text blocks; Responses API emits `input_text`
-  with the same wrapper. (#356)
- **Attachments at workstream-creation time** —
-  `POST /v1/api/workstreams/new` accepts `multipart/form-data` (one
-  `meta` JSON field plus 0..N `file` parts).  Files are validated and
-  reserved onto the first turn before the dispatch worker fires; failure
-  rolls back the fresh workstream so no orphan rows leak.  Web UI
-  (new-workstream modal + dashboard composer), Python SDK, and
-  TypeScript SDK all gained attachment support.  Cluster routing
-  (`/v1/api/route/workstreams/{ws_id}/attachments`) extended to forward
-  multipart bodies + preserve upstream headers (CSP, Content-Disposition).
-  SDKs auto-generate `ws_id` client-side so cluster-routed callers can
-  bind the body to the owning node before it lands. (#362)
- **Slack channel adapter** (Socket Mode) — mirrors the Discord adapter:
-  per-user channel sessions via configurable slash command, DM routing
-  without slash command, SSE event consumption, tool approval buttons
-  with per-user owner enforcement, plan-review approve / request-changes
-  modal, notification reply routing back into the workstream, and
-  session recovery after restart via persisted recoverable route keys
-  (the bot re-subscribes to existing Slack-routed workstreams when it
-  comes back).  Install with `pip install 'turnstone[slack]'`. (#355)
- **Console admin UX support for Slack** — channel-link modal offers
-  Slack alongside Discord; skill notify-on-complete forms expose a
-  per-row channel-type dropdown (and no longer hardcode `discord`);
-  per-platform `.scope-discord` / `.scope-slack` badge classes with
-  theme-aware tokens (`--discord` / `--slack`) so light theme passes
-  WCAG AA. (#365)
- **Per-call plan/task model selection** — `plan_model` and `task_model`
-  are now distinct from the conversation model and from each other,
-  with configurable reasoning effort per agent.  Three layers:
-  - **Backend split** (`#54dd557`) — `ModelRegistry` gains `plan_model`,
-    `task_model`, `plan_effort`, `task_effort`; per-kind overrides win
-    over the legacy `agent_model`, which still works as the single-knob
-    fallback.  `resolve_agent_alias(kind)` and `resolve_agent_effort(kind)`
-    centralise resolution.  Loader validates effort against
-    `{none, minimal, low, medium, high, xhigh, max}` with warn+drop on
-    typos.
-  - **Runtime configurability** (`#360`) — `ConfigStore` admin tab in
-    the console UI lets operators switch alias and reasoning effort per
-    agent **without restarting**.  `INHERIT_EMPTY_LABEL_KEYS` shows
-    `(inherit)` for empty effort selections — distinct from the literal
-    `none` choice which actually disables reasoning.  Routing overrides
-    apply on `/v1/api/_internal/config-reload` (admin saves), and
-    `model-reload` short-circuits when nothing changed so no in-flight
-    clients churn.
-  - **Per-call override** (`#361`) — the calling LLM can pass
-    `model="<alias>"` to `plan_agent` or `task_agent` to override the
-    operator-configured per-kind model for that one invocation.  Tool
-    descriptions list the live registered aliases (refreshed when the
-    operator hits "sync to nodes"), so the LLM always sees current
-    options.  Bad aliases return a corrective error dict listing the
-    available choices.  No whitelist — cost control is intentionally
-    ceded to the model.  Plan-retry path reuses the alias so coaching
-    reflects real model behaviour. (#360, #361)
- **Provider capability passthrough** — resolved per-model capabilities
-  (vision, reasoning, native web search, thinking_mode, token_param,
-  etc.) flow through to provider clients via a new `capabilities`
-  parameter on `create_streaming` / `create_completion`, so feature
-  gating no longer relies on string matching and admin-UI / config.toml
-  overrides actually reach the provider.  Defensive shallow-copy in
-  `_finalize_extra_body` so callers reusing the same dict across models
-  are safe; deep-merge of `chat_template_kwargs` so operators can
-  extend instead of silently overwriting. (#352)
- **Server compatibility layer for local model servers** — vLLM and
-  llama.cpp profiles suggest the right thinking mode and per-server
-  workarounds (`skip_special_tokens` for vLLM, `reasoning_format` for
-  llama.cpp) during model detection.  Admin UI gains structured fields
-  for server type, thinking mode, and extra body params, hidden for
-  non-local providers (openai/anthropic/google).  New `thinking_param`
-  text field surfaces the alias name (default `enable_thinking`;
-  Granite/DeepSeek use `thinking`).  Verified end-to-end against real
-  vLLM (Gemma 4 31B) and llama.cpp (Gemma 4 E4B) servers. (#352)
- **Claude Opus 4.7 support** — `claude-opus-4-7` capability entry
-  (1M ctx, 128K output, adaptive thinking, `supports_temperature=False`,
-  `thinking_display=summarized`).  New `ModelCapabilities.thinking_display`
-  field — Opus 4.7 omits thinking by default but always sends summarized
-  blocks back through the provider boundary.  Adds `xhigh` effort level
-  to the global mapping and to Opus 4.7's `effort_levels`; admin-console
-  skill-template dropdowns gained `xhigh` and `max` options.  Reasoning
-  effort label capitalization aligned across all console dropdowns.
-  (#357 — also in 1.3.1)
- **Dashboard composer refactor** — unified single-flow create from the
-  per-node dashboard.  Multi-line textarea + collapsible Options panel
-  (model / judge / skill) + paperclip + drag-drop / paste-image + chip
-  strip.  Submit-button label dynamically toggles between `Create`
-  (empty) and `Send` (text or attachments staged); Enter and click both
-  go through the same `dashboardSubmit()`.  Replaces the inconsistent
-  prior split where Enter created+sent raw and the button opened a
-  separate modal.  Options panel state persists in `localStorage`;
-  active non-default selections render as an inline summary chip beside
-  the Options button; drag-over shows an explicit "Drop to attach"
-  overlay.  The tab-bar `+` new-workstream modal also gained a paperclip
-  + chip strip + first-message field so the same flow is reachable from
-  both entry points. (#362, #366)
- **Workstream attachments — orphan reservation sweep** — periodic
-  background sweep clears `reserved_for_msg_id` on rows whose
-  `reserved_at` exceeds a 1-hour threshold, self-healing reservations
-  leaked by process crashes between reserve and consume.  Backed by a
-  partial index on `(reserved_at) WHERE reserved_at IS NOT NULL` so the
-  scan stays cheap as the consumed-history grows.  Threshold tracks
-  reservation age, not upload age, so a long-pending fresh send can't
-  be racially unreserved. (#363)
- **`SendResponse` extended** — `attached_ids`,
-  `dropped_attachment_ids`, `priority`, `msg_id` fields exposed in
-  Pydantic + TypeScript SDKs so attachment-aware clients can detect
-  partial reservations and dequeue queued messages. (#365)
-
-### Changed
-
- **`plan_model` and `task_model` now split** from the conversation
-  model and from each other — operators who rely on a single model for
-  all three should set both `plan_model` and `task_model` explicitly in
-  their config; otherwise both default to the conversation model so
-  behaviour is unchanged. (#54dd557)
- **Channel notify-on-complete `channel_type` is no longer hardcoded
-  in the admin UI** — operators creating notify targets through the
-  skill admin form previously got `channel_type: "discord"` regardless
-  of what they wanted.  Existing skill JSON values are unaffected; only
-  newly created targets through the form differ. (#365)
- **Slack adapter approval previews** — capped at 600 chars per item
-  with a 2700-char total budget so multi-tool approval batches never
-  exceed Slack's 3000-char `section.text` limit.  Truncated batches
-  show a `…and N more (preview truncated)` suffix. (#365)
- **PostgreSQL deployment image** swapped from `bitnami/pgbouncer` to
-  `edoburu/pgbouncer` to track upstream releases and reduce image size.
-  Environment variables remapped to the edoburu naming, ports updated
-  to match documented expectations, and the Kubernetes Helm Chart link
-  in the deployment docs now points at the same container.  Review
-  your helm values if you depend on `bitnami`-specific environment
-  variable conventions. (#353)
-
-### Fixed
-
- **`plan_resolved` SSE broadcast** — when one client resolved a plan
-  approval, other clients viewing the same workstream now have the
-  approval card dismissed in sync. (#87a9af1)
- **Slack notification reply routing** — one notification reply
-  previously pinned every later assistant response for that workstream
-  to the notification thread until the bot restarted.  Reply-route
-  override now clears on `StreamEndEvent`. (#365)
- **Slack plan-review mrkdwn fence** — plan content containing triple
-  backticks (very common — plans often quote code) no longer breaks the
-  surrounding fence and lets later content render as live markup.  The
-  shared `_sanitize_slack_preview` helper splices a zero-width space
-  inside any ``` ``` `` sequence while keeping single backticks
-  readable. (#365)
- **Slack-routed workstreams now load the chat-specific system prompt**
-  via `client_type="chat"`, matching Discord. (#365)
- **`/v1/api/workstreams/new` no longer emits a phantom
-  `ws_created`/`ws_closed` SSE pair** when attachment validation
-  rejects a multipart create.  Validation runs before the broadcast so
-  failed creates are silent on dashboards. (#362)
- **Multipart Content-Type boundary preservation** in console routing
-  proxy — `boundary=` parameter is case-sensitive and was being
-  lowercased before forwarding to the upstream node, breaking parsing
-  for clients that used mixed-case boundaries (most browsers). (#362)
- **Local-theme contrast for new badge colors** — `.scope-discord` and
-  `.scope-slack` first shipped with raw hex that failed WCAG AA on
-  light theme (1.8:1 / 2.4:1).  Theme-aware `--discord` / `--slack`
-  tokens with proper light variants now pass. (#365)
- **Cross-user attachment fetch hardening** — `get_attachment_content`
-  now scopes the row by `user_id` in addition to `ws_id`, so an
-  unowned workstream can't be a vector for cross-user blob fetches via
-  attachment-id guessing. (#356)
- **Attachment-list DoS guard** — `/v1/api/send` rejects
-  `attachment_ids` lists longer than the per-(ws, user) pending cap
-  with a 400, preventing hostile clients from blowing up the storage
-  `IN (...)` clause. (#356)
- **Bounded LRU for upload locks** — the per-(ws, user) attachment
-  upload-lock map now evicts the oldest unlocked entries past a soft
-  cap, so the in-process map can't grow unbounded on long-running
-  nodes. (#356)
- **3.12 CI deadlock on attachment uploads** — the upload-lock was
-  initially an `asyncio.Lock`, but Starlette's `TestClient` runs each
-  request on a fresh anyio task / event loop, so the cached lock's
-  `_waiters` bound to the first loop and a later request would block
-  on a Future from a closed loop (silent deadlock).  Switched to
-  `threading.Lock` — loop-agnostic, and the critical section is one
-  COUNT + one INSERT.  Same root cause is reproducible against any
-  Starlette TestClient harness on Python ≥ 3.10; 3.12 surfaces it
-  more often.  Production users on a single event loop weren't
-  affected, but the test environment was. (#356)
-
-### Security
-
- **Slack approval per-user authentication** — only the session owner
-  can click Approve/Deny on a Slack tool-approval card.  Without this,
-  any channel member with view access could approve dangerous tool
-  calls initiated by someone else. (#355)
- **Attachment ownership masking** — cross-user/cross-workstream
-  attachment ID lookups return 404 (not 403) so non-owners can't
-  enumerate workstream existence by response code. (#356)
- Bumped Debian base image; remaining unfixable `jq` CVEs are
-  documented and exception-listed. (#aaea4d3)
-
-### Database migrations
-
- **`037_workstream_attachments`** — new `workstream_attachments` table
-  with the lifecycle columns described above.  Indexes for ws_id,
-  pending lookups, message linkage, and reservation scoping.
- **`038_workstream_attachments_reserved_at`** — adds `reserved_at`
-  column for the orphan-sweep staleness signal, plus a partial index
-  on `reserved_at IS NOT NULL` so the periodic scan is cheap.
-
-Both migrations are additive and idempotent, and the server applies
-them automatically on first startup against an existing 1.3.x database.
-No manual `alembic upgrade` step is required — though running it
-manually beforehand (e.g. as part of a phased deploy) remains safe.
-
-### SDK
-
-Python + TypeScript clients gained:
-
- `AttachmentUpload` type
- `upload_attachment(ws_id, filename, data, mime_type=None)`
- `list_attachments(ws_id)`
- `get_attachment_content(ws_id, attachment_id) → bytes / Blob`
- `delete_attachment(ws_id, attachment_id)`
- `send(message, ws_id, attachment_ids=...)` (extended)
- `create_workstream(..., attachments=[...])` — multipart variant with
-  client-side `ws_id` generation for cluster-routed callers
- Console SDK: `route_create_workstream(attachments=...)`,
-  `route_upload_attachment`, `route_list_attachments`,
-  `route_get_attachment_content`, `route_delete_attachment`
- Refusal of `attachments + target_node` combination at the SDK
-  boundary (the multipart routing layer doesn't honor `target_node`,
-  so silently picking the wrong node is now an explicit error)
- `PlanResolvedEvent` SSE event with type guard, dispatched when one
-  client (e.g. mobile) resolves a plan so other connected clients can
-  dismiss their plan-approval modal in sync.  Available in both the
-  Python and TypeScript SDKs. (#87a9af1)
-
-### Operational
-
- **CI vendor-asset auto-download covers `hls.js`** — the
-  `vendor-js.yml` workflow previously only iterated katex/hljs/mermaid,
-  so Renovate bumps for `hls.js` failed the wheel-completeness check
-  and required manual file downloads.  Detection loop now includes
-  `hls`, so future Renovate bumps are merge-ready without intervention.
-  (#354)
-
-### Contributors
-
-Thanks to the people who made this release happen — especially the
-external contributors who picked up substantial pieces of work:
-
- **[@daoxley](https://github.com/daoxley)** — designed and shipped
-  the Slack channel adapter (Socket Mode bot, per-user sessions,
-  approvals, plan-review, notification routing).  Major new feature
-  surface in #355.
- **[@pizzaandcheese](https://github.com/pizzaandcheese)** — replaced
-  the deprecated bitnami pgbouncer image with the edoburu image,
-  remapped environment variables, ports, and helm chart references.
-  Operationally important for anyone running our reference Postgres
-  deployment (#353).
- Renovate kept dependencies and the JS vendor tree current via
-  several automated bumps.

 ## Architecture

 **Single-node**: Client → Server (direct HTTP + SSE). No external dependencies beyond the database.

-**Multi-node**: Client → Console (rendezvous routing proxy) → Server nodes. The console picks the target node for each workstream via rendezvous (HRW) hashing over the live service registry — pure function of `(ws_id, live_nodes)`, no stored bucket state, deterministic across readers. A node join or drop only re-routes the keys that score highest on the affected node.
+**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.

-# Bulk endpoint shape contract
-
-Turnstone exposes several endpoints and tool calls that take multiple
-ids and return a per-id outcome.  Over the last few phases two
-**distinct** response shapes have settled, one per semantic category.
-This doc codifies both so a future endpoint author can pick the right
-shape by semantics instead of by coin-flip.
-
-Existing bulk endpoints at time of writing:
-
-| Endpoint / tool                                         | Category                 | Response shape                          |

-## Why two shapes
-
-The ask-to-outcome mapping is fundamentally different between the
-two categories, and a one-size-fits-all envelope ends up papering
-over distinctions the caller genuinely needs to branch on.
-
-**Bulk read / bulk create-with-payload.**  Each input id (or batch
-index) carries a *request-side* concept — "give me the live block
-for this ws_id" or "spawn a child with this spec" — and each
-successful output carries a *payload* — the live block, or the new
-workstream's identifying triple.  The interesting distinction on
-failure is *ownership / validation* (caller can't see that id, spec
-was malformed) — independent of the storage state.
-
-**Cascade mutation.**  The action is uniform across every id (cancel
-this subtree, close this child).  The interesting distinctions on
-outcome are *did it reach the terminal state?* (succeeded / already
-was there / the dispatch itself failed) — driven by the storage
-state plus transport reliability, not by the caller's input.
-
-Trying to unify these forces either:
-
- a stateless `denied` bucket that has to carry "already gone"
-  *and* "you don't have permission" *and* "transport failed" with a
-  separate reason string — reviewers end up string-matching to branch.
- or a per-item-payload map for cascade mutations where every
-  successful value is the same sentinel — carrier with no payload.
-
-So: two shapes, one per category.  The rest of this doc spells out
-each.
-
---
-
-## Shape A — bulk read / bulk create-with-payload
-
-```json
-{
-  "results":  { "<key>": <value-or-null>, ... },
-  "denied":   [ "<key>", ... ],
-  "truncated": false
-}
-```
-
-**`results`** is a key-indexed map of the positive-path payload.
-The key is the input id for read endpoints (`cluster/ws/live` uses
-the ws_id), or the input-array index (stringified) for create
-endpoints that want ordering preserved (`spawn_batch` uses `"0"`,
-`"1"`, ...).  The value is whatever the endpoint produces per
-success — a live block, a `{ws_id, name, node_id, status}` triple,
-etc.  A `null` value (read endpoints only) means "the id existed and
-you own it, but the live block wasn't available" — distinct from
-"denied".
-
-**`denied`** is the negative-path list.  For read endpoints it's a
-flat list of ids (preserves input order so callers can re-zip
-against their input).  For create endpoints with per-item payloads
-it's a list of `{idx, reason}` objects (`spawn_batch`'s validation
-and spawn-error rows; also the operator-reject surface when per-item
-selective-deny ships).  Include every reason that's *not* the
-positive path — authz, ownership, validation, already-consumed,
-spawn failure — so callers don't branch on status codes.
-
-**`truncated`** is a boolean set to `true` when the server's
-per-endpoint input cap was exceeded and the tail was dropped.  The
-endpoint docs each spell out the cap (50 for `cluster/ws/live`).
-`spawn_batch` hard-errors on overflow instead of silently
-truncating — it omits the field entirely rather than carry a
-permanently-false flag.
-
-### Example — `cluster/ws/live`
-
-```http
-GET /v1/api/cluster/ws/live?ids=a1b2,c3d4,nonexistent,foreign HTTP/1.1
-```
-
-```json
-{
-  "results": {
-    "a1b2": {"state": "running", "tokens": 12843, "activity": "..."},
-    "c3d4": null
-  },
-  "denied": ["nonexistent", "foreign"],
-  "truncated": false
-}
-```
-
-Callers that need ordered output zip their original id list against
-this map; ids in `denied` drop out of the zip cleanly.  A live-block
-`null` doesn't route to `denied` — the row exists and the caller
-owns it; the node is just currently unreachable.
-
-### Example — `spawn_batch`
-
-```json
-{
-  "results": {
-    "0": {"ws_id": "d4e5f6...", "name": "csrf-audit", "node_id": "gpu-3", "status": 200},
-    "2": {"ws_id": "f1a2b3...", "name": "xss-audit",  "node_id": "gpu-1", "status": 200}
-  },
-  "denied": [
-    {"idx": 1, "reason": "skill not found: nonexistent-skill"}
-  ]
-}
-```
-
-Indexes are stringified to keep the envelope JSON-safe and
-consistently-typed across the read and create cases.
-
---
-
-## Shape B — cascade mutation
-
-```json
-{
-  "status":       "ok",
-  "<bucket>":     [ "<ws_id>", ... ],
-  "failed":       [ "<ws_id>", ... ],
-  "skipped":      [ "<ws_id>", ... ]
-}
-```
-
-Where `<bucket>` is the endpoint-specific name for "succeeded" —
-`cancelled` for `stop_cascade`, `closed` for `close_all_children`.
-The three buckets partition the input set exactly once:
-
-| Bucket        | Meaning                                                                       |
-|---------------|-------------------------------------------------------------------------------|
-| `<bucket>`    | Action dispatch accepted; target reached the intended terminal state.         |
-| `failed`      | Dispatch returned a non-404 error (transport issue, upstream 5xx, exception). |
-| `skipped`     | Upstream 404 — stale registry entry, row already deleted, or peer gone.       |
-
-The split between `failed` and `skipped` is load-bearing.  `failed`
-is actionable — the operator may want to retry, or the cascade may
-be partial.  `skipped` is pre-resolved — the target is already in
-the terminal state the cascade was aiming at, so it's neither a
-win to report nor a fault to fix.
-
-### Example — `stop_cascade`
-
-```json
-{
-  "status": "ok",
-  "cancelled": ["child-1", "child-3"],
-  "failed":    [],
-  "skipped":   ["child-2"]
-}
-```
-
-A subsequent retry would target only `failed` ids, not `skipped`
-ones — the latter are already done.
-
-### Example — `close_all_children`
-
-```json
-{
-  "status": "ok",
-  "closed":  ["child-1", "child-3"],
-  "failed":  ["child-2"],
-  "skipped": []
-}
-```
-
-Same partition, different success-bucket name.  When `coord_client`
-is unavailable (session loaded but no HTTP client attached — a
-construction bug) every id goes to `failed` so the operator notices
-rather than getting a silent all-skipped response.
-
---
-
-## Guidance for future bulk endpoints
-
-1. **Pick by semantics, not by "what shape is nearby."**
-   - Mutation that's uniform across ids + terminal-state outcome?  →
-     **Shape B** (cascade mutation).
-   - Read or create where the input id carries payload, or where the
-     denial axis is independent of storage state?  →  **Shape A**
-     (bulk read / bulk create-with-payload).
-
-2. **Cap the input.**  Both shapes assume a bounded input — the
-   server rejects or silently truncates past the cap.  Document the
-   cap in the endpoint's OpenAPI description.  Shape A uses
-   `truncated: true` on quiet truncation; Shape B hard-errors on
-   overflow.
-
-3. **Match existing bucket names for the same semantic.**  Use
-   `failed` and `skipped` verbatim in Shape B — the per-endpoint
-   success bucket is the only slot that varies.  Use `results` and
-   `denied` verbatim in Shape A; the per-endpoint `<key>` /
-   `<value>` types vary.
-
-4. **Audit the verbose shape.**  Both endpoints emit a corresponding
-   audit event with the full before/after bucket lists — the SSE
-   stream and the in-process response give live feedback, but a
-   postmortem operator will read the audit row.  Use
-   `_emit_coord_audit` (coordinator-scoped) or `record_audit`
-   directly; don't inline.
-
-5. **Don't mix shapes within one endpoint.**  If a bulk endpoint
-   wants both partial-success creation AND per-item failure reasons
-   (like `spawn_batch` with its `{idx, reason}` denial rows), that's
-   Shape A with a richer denial element — not a blend with Shape B.
-

-## Slack Setup
-
-Slack uses **Socket Mode**, so no public URL or API Gateway is required — Slack
-connects outbound to the bot via a WebSocket. Install with:
-
-```bash
-pip install 'turnstone[slack]'
-```
-
-### 1. Create a Slack App
-
-1. Go to https://api.slack.com/apps and click **Create New App**
-2. Under **Settings > Socket Mode**, enable Socket Mode. This generates an
-   **App-Level Token** (prefix `xapp-`) — copy it.
-3. Under **OAuth & Permissions**, add these **Bot Token Scopes**:
-   `chat:write`, `chat:write.public`, `channels:history`, `im:history`,
-   `groups:history`, `mpim:history`, `reactions:write`, `commands`
-4. Under **Event Subscriptions** (Socket Mode delivers events), subscribe
-   to bot events: `message.channels`, `message.im`, `message.groups`
-5. Under **Slash Commands**, create a command (default `/turnstone`)
-6. Install the app to your workspace to generate the **Bot User OAuth
-   Token** (prefix `xoxb-`).
-
-### 2. Configure Turnstone
-
-**Environment variables** (recommended for Docker):
-
-```bash
-TURNSTONE_SLACK_TOKEN=xoxb-...        # Bot User OAuth Token
-TURNSTONE_SLACK_APP_TOKEN=xapp-...    # App-Level Token (Socket Mode)
-TURNSTONE_SLACK_CHANNELS=             # optional, comma-separated channel IDs
-TURNSTONE_SLACK_SLASH_COMMAND=/turnstone
-```
-
-**CLI flags** (bare-metal):
-
-```bash
-turnstone-channel \
-  --slack-token "xoxb-..." \
-  --slack-app-token "xapp-..." \
-  --slack-slash-command /turnstone \
-  --server-url http://localhost:8080
-```
-
-The Slack and Discord adapters can be enabled together — pass tokens for
-both and the gateway hosts both adapters in one process.
-
-### 3. Usage
-
- **DM the bot**: messages sent directly to the bot create a workstream
-  scoped to that DM; the slash command is not required.
- **Slash command**: `/turnstone <message>` in any channel the bot can
-  see starts a per-user channel session.
- Tool approvals render as Slack **Block Kit** buttons; only the user
-  who owns the workstream can approve/reject.
- Plan reviews render as a modal with approve / request-changes actions.
- Notifications and reply routing work identically to Discord.
- Session recovery: persisted channel routes are re-subscribed when the
-  bot restarts, so existing Slack conversations keep flowing.

-```
-
-```http
-HTTP/1.1 201 Created

-
-All three body fields are optional — an empty body still creates a
-coordinator with an auto-generated name and no initial message.
-Returns **503** with a remediation message when the cluster isn't
-configured with a coordinator model; see
-[`coordinator.model_alias`](settings.md) to set one.
-
-**SSE implication:** the `ws_created` event fires on the cluster-wide
-stream (`/v1/api/cluster/events`) once the row is committed.  Per-ws
-subscribers (step 2) see the session warm up as token traffic starts.

-## 2. Subscribe to the per-coordinator event stream
-
-```http
-GET /v1/api/coordinator/{ws_id}/events HTTP/1.1
-Accept: text/event-stream
-Authorization: Bearer <token>
-```
-
-One persistent SSE connection per browser tab / SDK caller — the
-console fans each event out to every listener queue (cap 500 events
-per queue, put_nowait drop on overflow).  Events come in flat JSON
-with a `type` field.  The recurring shapes a UI has to handle:
-
-| `type`              | Emitted when                                                                               | Payload highlights |
-|---------------------|--------------------------------------------------------------------------------------------|--------------------|
-| `thinking_start` / `thinking_stop` | Model has entered / exited a reasoning block                                | — |
-| `reasoning`         | Reasoning-token stream chunk (when the model exposes it)                                   | `text` |
-| `content`           | Assistant-content stream chunk                                                             | `text` |

-| `tool_result`       | A tool call completed (success or error)                                                   | `call_id`, `name`, `output`, `is_error?` |
-| `tool_output_chunk` | Streaming tool output (e.g. long bash command)                                             | `call_id`, `chunk` |
-| `approve_request`   | One or more tool calls need operator approval                                              | `items: [{call_id, header, preview, func_name, approval_label, needs_approval}]` |
-| `approval_resolved` | Operator answered the approval prompt                                                      | `approved`, `feedback` |
-| `state_change`      | Worker-thread state transition                                                             | `state` ∈ `running`, `thinking`, `attention`, `idle`, `error` |
-| `status`            | Token usage + context-window snapshot (fires on every streaming tick)                      | `prompt_tokens`, `completion_tokens`, `total_tokens`, `context_window`, `pct`, `effort`, `cache_creation_tokens`, `cache_read_tokens` |
-| `rename`            | Session's display name changed                                                             | `name` |

-| `output_warning`    | Output guard flagged a tool result                                                         | `call_id`, `risk_level`, `flags` |
-| `child_ws_created`  | A direct child of this coord was just created (fan-out from the cluster bus)              | `child_ws_id`, `node_id`, `name`, `parent_ws_id` (`ws_id` in the envelope is always the coord's own id) |
-| `child_ws_state`    | A direct child transitioned state                                                          | `child_ws_id`, `state` |
-| `child_ws_closed`   | A direct child closed                                                                      | `child_ws_id` |

-
-**Reconnection contract:** a freshly-opened SSE connection receives
-the current snapshot of any pending tool approval (`approve_request`
-is re-sent if unresolved) and any in-flight `wait_*` / `batch_*`
-indicator — so a tab refresh mid-approval doesn't strand the
-operator.
-
---
-
-## 3. Send the first user message
-
-```http
-POST /v1/api/coordinator/{ws_id}/send
-Content-Type: application/json
-
-{"message": "audit /auth for CSRF handling across all active routes"}
-```
-
-```http
-HTTP/1.1 200 OK
-{"status": "ok"}
-```
-
-The message is queued for the worker thread at its next tool-result
-seam (so you can send follow-ups mid-conversation without corrupting
-the in-progress turn).  On the SSE stream you'll see `state_change`
-→ `thinking_start` → streaming `reasoning` / `content` / `tool_result`
-events, finishing with `state_change → idle` or an
-`approve_request` when the model invokes a gated tool.
-
---
-
-## 4. Inspect direct children
-
-```http
-GET /v1/api/coordinator/{ws_id}/children HTTP/1.1
-```
-
-```json
-{
-  "items": [
-    {"ws_id": "d4e5f6...", "name": "csrf-audit", "state": "running", "node_id": "gpu-3"},
-    {"ws_id": "e1f2a3...", "name": "xss-audit",  "state": "idle",    "node_id": "gpu-1"}
-  ],
-  "truncated": false
-}
-```
-
-The response key is `items`, not `children` — the endpoint shape
-follows the cluster-wide workstream-list idiom rather than the
-coordinator `list_workstreams` tool's (which uses `children`).
-Rows include every state stored for the parent (`running`, `idle`,
-`closed`, ...); the endpoint does not accept a state query param,
-so clients should inspect each row's `state` field and filter
-locally if they want to hide closed/deleted children.  Nested
-coordinator rows are dropped server-side so only interactive
-descendants appear.
-
---
-
-## 5. Inspect one workstream (storage + live block + tail)
-
-```http
-GET /v1/api/cluster/ws/{ws_id}/detail?message_limit=20 HTTP/1.1
-```
-
-```json
-{
-  "persisted": { "ws_id": "...", "state": "running", "parent_ws_id": "...", "kind": "interactive", ... },
-  "live":      { "state": "thinking", "tokens": 12843, "activity": "...", "pending_approval": null },
-  "tail":      [ {"role": "assistant", "content": "...", "tokens": 128}, ... ]
-}
-```
-
-Works for any workstream the caller has `admin.cluster.inspect` on,
-not just children of a single coordinator — useful for a cluster
-admin panel watching multiple coordinators at once.  `live` is
-`null` when the owning node is unreachable or has dropped the row
-from its dashboard cache; callers should degrade gracefully, not
-treat it as an error.
-
-For fan-out views, prefer
-[`GET /v1/api/cluster/ws/live?ids=a,b,c`](bulk-endpoints.md) — it
-collapses N per-row round-trips into one, returning the live block
-for every id in a `{results, denied, truncated}` envelope.
-
---
-
-## 6. Wait for fan-out (`wait_for_workstream`)
-
-`wait_for_workstream` is a **model-side tool**, not an HTTP endpoint
-— the coordinator's LLM invokes it with a list of child ws_ids, the
-session's worker thread blocks inside the tool, and a sequence of
-`wait_started` / `wait_progress` / `wait_ended` SSE events is emitted
-for the UI to drive a "waiting on N children" indicator.
-
-![wait_for_workstream sequence](diagrams/png/27-coordinator-wait-for-workstream.png)
-
-Key properties:
-
- **Caps** — up to 32 ws_ids per call, up to 600 seconds per call.
-  A coordinator that needs to wait on more children re-invokes the
-  tool with a fresh timeout.
- **Modes** — `mode="any"` returns as soon as one child reaches a
-  real terminal state (`idle` / `error` / `closed` / `deleted`);
-  `mode="all"` waits for every polled child.
- **Progress throttling** — the poll loop runs every 500 ms but the
-  SSE emission is diff-on-state-change plus a 5-second heartbeat.  A
-  600 s wait generates O(dozens) of progress events, not 1200.
- **Denied rows** — an id the caller doesn't own (cross-tenant) or a
-  missing row is reported as a `denied` state in the results dict;
-  `mode="any"` won't satisfy on a pure-denied list (the LLM should
-  treat it as a config error, not a completion).
-
-Prefer `wait_for_workstream` over polling `inspect_workstream` in a
-loop — a wait consumes one assistant turn regardless of how long the
-children take, whereas each `inspect_workstream` poll costs a full
-turn (plus judge, plus tokens).  On a fan-out of 3+ children this
-rounds to a 10× token-efficiency win.
-
---
-
-## 7. Governance — trust, restrict, stop_cascade, close_all_children
-
-These four endpoints let an operator steer a live coordinator session
-mid-flight.  All four emit an audit event tagged
-`coordinator.<action>` via the dedicated audit executor so a cascade
-burst can't starve audit writes.
-
-### `POST /trust` — auto-approve own-subtree sends
-
-```json
-POST /v1/api/coordinator/{ws_id}/trust
-{"send": true}
-```
-
-Flips `trust_send=true` on the live session.  Subsequent
-`send_to_workstream` calls that target a ws_id in the coordinator's
-own subtree skip the approval prompt; foreign ws_ids and other tool
-calls still go through the normal flow.  Requires both
-`admin.coordinator` AND `coordinator.trust.send` permissions (the
-second grants a service token the opt-in it otherwise wouldn't get).
-
-### `POST /restrict` — revoke tool access mid-session
-
-```json
-POST /v1/api/coordinator/{ws_id}/restrict
-{"revoke": ["spawn_workstream", "delete_workstream"]}
-```
-
-Unions the names into the session's revoked-tools set.  Additive and
-idempotent — calling twice with overlapping lists converges to the
-union.  Revocations don't survive a session close/reopen; operators
-opt in per session.  Cap 256 tool names per request, 128 chars each.
-
-### `POST /stop_cascade` — cancel the subtree
-
-```json
-POST /v1/api/coordinator/{ws_id}/stop_cascade
-{}
-```
-
-Cancels the coordinator's in-flight generation AND dispatches
-`cancel_workstream` through the routing proxy for every direct
-child in the in-memory registry.  Returns:
-
-```json
-{"status": "ok", "cancelled": ["child-1", "child-3"], "failed": [], "skipped": ["child-2"]}
-```
-
-Response uses the [cascade-mutation bulk shape](bulk-endpoints.md):
-`cancelled` = accepted, `failed` = dispatch error worth retrying,
-`skipped` = upstream 404 (already gone — stale registry entry or
-the row was deleted between snapshot and dispatch).  Grandchildren
-aren't touched directly; they sit behind their parent's cancel and
-propagate via the child's SSE stream.
-
-### `POST /close_all_children` — soft-close the direct fan-out
-
-```json
-POST /v1/api/coordinator/{ws_id}/close_all_children
-{"reason": "audit round complete"}
-```
-
-Response:
-
-```json
-{"status": "ok", "closed": ["c-1", "c-2"], "failed": [], "skipped": []}
-```
-
-Soft-close cascade bounded by the same semaphore as `stop_cascade`.
-The `reason` (up to 512 chars) propagates into each closed child's
-audit + `workstream_config` for postmortem.  Unlike `stop_cascade`
-this does NOT recurse into grandchildren — the model-facing tool
-that pairs with this endpoint asks for a bounded teardown of the
-coordinator's own fan-out.  For a full-subtree teardown, use
-`stop_cascade`.
-
-See [bulk-endpoints.md](bulk-endpoints.md) for why both endpoints
-share the cascade-mutation shape and how it differs from the
-`spawn_batch` / `cluster/ws/live` shape.
-
---
-
-## 8. Approve / cancel
-
-The `approve` endpoint is what resolves an `approve_request` SSE
-event.  The coordinator's worker thread is blocked inside
-`ui.approve_tools` waiting for this POST.
-
-```json
-POST /v1/api/coordinator/{ws_id}/approve
-{"approved": true, "feedback": null, "always": false}
-{"approved": false, "feedback": "spawn count looks too high — try 3 not 10"}
-{"approved": true, "feedback": null, "always": true}    // always-approve this tool name
-```
-
-`cancel` drops the in-flight generation but leaves the coordinator
-idle and open for a fresh `send`:
-
-```json
-POST /v1/api/coordinator/{ws_id}/cancel
-{}
-```
-
---
-
-## 9. Close
-
-```json
-POST /v1/api/coordinator/{ws_id}/close
-{}
-```
-
-Soft-closes the session — state persists, children keep running (use
-`close_all_children` or `stop_cascade` first to wind them down), the
-worker thread exits, SSE streams send a final `stream_end` and
-disconnect.  The row is reopenable via
-`POST /v1/api/coordinator/{ws_id}/open` so long as it hasn't been
-deleted.

-# Writing a coordinator-specific skill
-
-Skills are prompt-level personas that steer a Turnstone session
-toward a narrow task.  Most skills target **interactive** sessions —
-the single-workstream "do this thing" surface where the model wields
-`bash`, `edit_file`, `web_fetch`, and the rest of the maker toolset.
-
-A **coordinator skill** is different.  It runs on a session whose job
-is to orchestrate other sessions.  The toolset is smaller and
-narrower, the persona is an orchestrator instead of a maker, and the
-success metric is "did the plan resolve" instead of "did the code
-compile".  This doc covers the differences a skill author has to
-care about.
-
---
-
-## The two-surface model
-
-A row in `prompt_templates` carries a `kind` column (see
-[`turnstone/core/skill_kind.py`](../turnstone/core/skill_kind.py);
-migration 044 added the column).  Three values:
-
-| `SkillKind` enum     | Stored as                   | Visible in                                                                |
-|----------------------|-----------------------------|---------------------------------------------------------------------------|
-| `SkillKind.INTERACTIVE` | `"interactive"`          | Only the interactive-session activation path.  `list_skills` on a coord won't show it. |
-| `SkillKind.COORDINATOR` | `"coordinator"`          | Only the coordinator's `list_skills` tool.  Hidden from interactive activation pickers. |
-| `SkillKind.ANY`         | `"any"`                  | Both surfaces.  Default for legacy rows predating the classifier.        |
-
-The `kind` field is a `StrEnum` — drop-in ``str`` compatible — so
-DB rows, JSON payloads, and `==` comparisons all work without
-translation at the edge.
-
-When a coordinator calls `list_skills`, the SQL filter narrows to
-`kind IN ('coordinator', 'any')`.  When an interactive session picks
-a skill at activation, the filter narrows to
-`kind IN ('interactive', 'any')`.  A skill author tags once at
-creation; the two surfaces stay partitioned without any
-per-call filtering on the LLM side.
-
-**Tagging a new skill as coordinator-only** — set `kind` to
-`SkillKind.COORDINATOR` (or the literal string `"coordinator"`) when
-you POST to `/v1/api/admin/skills`.  Existing rows default to
-`SkillKind.ANY`; bump them to `COORDINATOR` if you've rewritten the
-prompt around the orchestrator toolset.
-
---
-
-## Tool surface differences
-
-Coordinator sessions receive a **fixed** tool set, defined in
-`turnstone/core/tools.py` as `COORDINATOR_TOOLS`.  Nothing a skill
-or MCP config can do adds to it.  Current members:
-
-| Tool                      | Category        | Notes                                                               |
-|---------------------------|-----------------|---------------------------------------------------------------------|
-| `spawn_workstream`        | delegate        | Create one child.  Requires approval.                               |
-| `spawn_batch`              | delegate        | Create up to 10 children in one approval.  Partial-success shape.   |
-| `inspect_workstream`      | observe         | Read state + tail of one child.  Auto-approved (no mutation).       |
-| `list_workstreams`        | observe         | List the direct children (same shape as `/children` endpoint).      |
-| `wait_for_workstream`     | block           | Block until one/all listed children hit a terminal state.           |
-| `send_to_workstream`      | steer           | Queue a follow-up message to a running child.                        |

-Explicitly **not** in the coordinator set:
-
- `bash` / `edit_file` / `write_file` / `append_file` / `diff_file` — no local FS.
- `read_file` / `search` — no local FS reads.
- `web_fetch` / `web_search` — no direct web access.
- `task_agent` / `plan_agent` — sub-agent tools are zeroed on coord sessions.
- `memory` / `recall` / `notify` / `watch` / `read_resource` / `use_prompt` / `skill` — the orchestrator's "memory" is its children's outputs; these UX / persistence tools belong to interactive sessions.
-
-If your skill needs a coordinator to "run a command" or "read a
-file", write the delegate pattern instead: spawn a child with an
-appropriate skill, `wait_for_workstream`, then `inspect_workstream`
-for the output.  The coordinator stays the orchestrator.
-
---
-
-## Persona differences
-
-Interactive skills compose on top of `base_interactive.md` — a
-"maker" persona: get the work done, use the tools, edit the code,
-close the loop.
-
-Coordinator skills compose on top of
-[`base_coordinator.md`](../turnstone/prompts/base_coordinator.md) —
-an "orchestrator" persona: decompose, delegate, monitor, synthesise.
-The base text is short but sets the tone every coordinator skill
-inherits:
-
-> You are a coordinator on a small, focused infrastructure team.
-> Your role is to orchestrate work across the cluster...  You do
-> not edit files, run shell commands, browse the web, or manipulate
-> the codebase directly.  Children do that.
-
-Write your skill's system prompt to *add* task-specific orchestration
-hints on top — don't re-explain the role, don't paste tool JSON,
-don't try to override the "no direct action" contract.  Keep the
-additions to: (a) the specific kind of work this skill delegates;
-(b) the preferred skill tags for children; (c) the synthesis shape
-the skill should end on.
-
---
-
-## `task_list` integration
-
-`task_list` is the coordinator's scratchpad — a persisted, ordered
-list of rows with fields `{id, title, status, child_ws_id, created,
-updated}` that only this coordinator sees.  Children don't see it;
-the user does via the sidebar.  Five actions: `add`, `update`,
-`remove`, `reorder`, `list` (only `list` is auto-approved; the
-mutators go through the approval flow).
-
-The input schema refers to rows by `task_id`; the persisted row
-object exposes the same id as `id`.  The `child_ws_id` field is a
-free-form label the skill sets to link a task to a spawned
-workstream — it is NOT validated against the workstreams table, so
-a skill can set it to a placeholder before `spawn_workstream`
-returns or keep it pointing at a closed child for later audit.
-
-A skill's initial prompt can seed the task list by calling
-`task_list(action="add", title=...)` as its very first tool calls —
-the user gets a visible plan before any child is spawned, and the
-coordinator's future self has something concrete to iterate on.
-Status transitions (`pending` → `in_progress` → `done` / `blocked`)
-are the skill's main feedback loop: mutate the task when the child
-covering it finishes, not when the child starts.  Use
-`task_list(action="update", task_id=..., child_ws_id=<ws_id>)` to
-link a task to the child that owns it once spawn returns.
-
-A final gotcha: parallel tool dispatch does NOT serialise reads
-after writes in the same batch.  If a skill issues an `update` and
-a `list` in one parallel tool batch, the `list` response may reflect
-the pre-update state.  Dispatch mutate and list serially (one
-tool_use turn each) when the list must observe the mutation.
-
-Keep the tasks coarse-grained — one per child, roughly.  A 20-task
-list for a 3-child fan-out is noise; a 1-task list for a 5-child
-fan-out loses the plan.  The sidebar renders tasks as the operator's
-mental model of "what the coord thinks it's doing".
-
---
-
-## Referencing children by `ws_id`
-
-Every ws_id returned by `spawn_workstream` / `spawn_batch` is a
-**full 32-char hex string**.  The skill's system prompt must not
-invent ws_ids — a model that hallucinates `"child-1"` or `"ws-abc"`
-hits the tenant guard in `CoordinatorClient._is_own_subtree`, which
-validates ws_id against `parent_ws_id=coord_ws_id` AND
-`user_id=owner` in storage.  The rejection shape varies by tool:
-
- **Mutating ops** (`send_to_workstream`, `close_workstream`,
-  `cancel_workstream`, `delete_workstream`) return
-  `{"error": "workstream not in coordinator subtree: <ws_id>", "status": 404}`
-  — the skill should treat this as a tool error, not an empty result.
- **`inspect_workstream`** returns `{"error": "workstream not found: <ws_id>"}`
-  (same shape as a genuinely missing row, so the guard can't be
-  used as an existence oracle).
- **`wait_for_workstream`** reports the offending id with
-  `state="denied"` in its `results` dict; `mode="any"` won't
-  satisfy on a pure-denied list, so a hallucinated id won't trick
-  the wait into reporting "complete".
-
-Pattern: capture each spawn result in the next tool call's input.
-The JSON tool-result carries `{"ws_id": "...", "name": "...",
-"node_id": "...", "status": 200}`; the model should extract the
-ws_id and pass it to `inspect_workstream` / `wait_for_workstream` /
-`send_to_workstream` / `close_workstream` verbatim.
-
-A UI that wants human-readable identifiers should render the `name`
-field and keep the ws_id as the click-through key.
-
---
-
-## `wait_for_workstream` vs `inspect_workstream`
-
-Two distinct semantics, different cost profiles:
-
- **`wait_for_workstream(ws_ids=[...], timeout=60, mode="any")`** —
-  blocks inside a single tool call until one (or all, for `mode="all"`)
-  of the listed children reaches a terminal state (`idle`, `error`,
-  `closed`, `deleted`).  The worker thread blocks up to `timeout`
-  seconds; the assistant turn remains a single round-trip regardless
-  of how long the wait actually takes.  Prefer this for "the plan
-  needs child X to finish before the next step."
- **`inspect_workstream(ws_id=...)`** — single read of the child's
-  state + tail.  Costs a full assistant turn (judge, tokens, stream).
-  Prefer this for "what does the final message say?" after the child
-  has already resolved (via `wait_for_workstream` or a known
-  transition).
-
-Rule of thumb: wait once for a fan-out, then inspect once per
-child for the content.  A loop of inspect-every-few-seconds is a
-token-burning antipattern — on 3+ children it rounds to a 10×
-efficiency hit over a wait+inspect pair.
-
---
-
-## Common coordinator patterns
-
-Three patterns cover most coordinator skills.  Pick the one that
-matches the task, or combine them deliberately.
-
-### Pattern 1 — delegate-and-summarise
-
-One specialist child, one focused brief, one synthesis message back
-to the user.  Appropriate when the user's request is "run the thing
-and tell me what happened" and the work fits in one workstream.
-
-```
-task_list(action='add', title='audit /auth for CSRF')
-spawn_workstream(skill='engineer', initial_message='audit /auth ...')
-wait_for_workstream(ws_ids=[<child>], timeout=300)
-inspect_workstream(ws_id=<child>)
-→ synthesise the final message into a user-facing response
-task_list(action='update', task_id='t_01', status='done')
-close_workstream(ws_id=<child>, reason='audit complete')
-```
-
-### Pattern 2 — fan-out-and-synthesise
-
-N children running in parallel, each with a distinct brief, all
-waited-on together, then synthesised.  Appropriate when the user's
-request naturally decomposes into independent subtasks.
-
-```
-task_list seeds:
-  t_01 benchmark Anthropic 4.7 latency on summarisation
-  t_02 benchmark OpenAI GPT-5.2 latency on summarisation
-  t_03 benchmark Gemini 2.5 latency on summarisation
-spawn_batch(children=[...3 briefs...])
-wait_for_workstream(ws_ids=[c1, c2, c3], mode='all', timeout=600)
-inspect_workstream(ws_id=c1); ...(c2); ...(c3)
-→ synthesise head-to-head comparison
-task_list → all done
-close_all_children(reason='benchmark complete')
-```
-
-Prefer `spawn_batch` over 3 individual `spawn_workstream` calls —
-one approval instead of three, one audit trail, deterministic
-sibling ordering.  Pair with `wait_for_workstream(mode='all')` and
-`close_all_children(reason=...)` to wind the fan-out down in one
-approval each.
-
-### Pattern 3 — plan-then-delegate
-
-The coordinator first uses its own reasoning to carve the plan,
-records it in `task_list`, then spawns children that each own one
-task.  Appropriate when the user's request is "figure out how to X"
-and the coordinator's planning step is itself valuable.
-
-```
-→ coord reasons about the shape of the work
-task_list(action='add', title='...') × N   # the plan, visible in the sidebar
-for task in tasks:
-    spawn_workstream(skill=..., initial_message=task.brief)
-    task_list(action='update', task_id=task.id, notes='ws=<child_ws_id>')
-wait_for_workstream(ws_ids=[...], mode='all', timeout=...)
-for child in children:
-    inspect_workstream(ws_id=child)
-    task_list(action='update', task_id=..., status='done', notes='result summary')
-→ synthesise
-```
-
-The key distinction from Pattern 2: the plan is an artifact the user
-can see and interact with (via the sidebar).  If the coordinator's
-reasoning-pass was wrong about the decomposition, the user can
-course-correct before any child runs.
-
---
-
-## Testing a coordinator skill
-
-Coordinator sessions are hosted on the console, not on a node.
-Integration tests that drive a real coord session live under
-`tests/test_coordinator_end_to_end.py` — they spin a console with
-an in-memory SQLite backend and a fake upstream node, then drive
-the session through its HTTP surface.
-
-For a new coordinator skill:
-
-1. Write the skill prompt as a string and pass it to the
-   `coord_session` fixture's `skill=` kwarg (see
-   `tests/test_coordinator_tools.py` for the pattern).
-2. Build a small fake cluster: one node + two children via
-   `mgr.register_children(coord.id, ["child-1", "child-2"])`.
-3. Drive the session with seeded tool_call dicts matching the
-   provider layer's shape.  The unit-level tests in
-   `tests/test_coordinator_tools.py` show the helper (`_tc(name,
-   args, call_id)`).
-4. Assert the skill's decision shape — which tools fire in what
-   order, what the task_list looks like at the end, which
-   `_error` reasons appear on the denied-path.
-
-A full end-to-end test isn't required for every skill; a
-prepare-step unit test that asserts "given this initial message, the
-first tool call is X with Y args" is usually sufficient to catch
-persona drift without a real LLM in the loop.

 # Consistent Hash Ring — Reference Design

-**Status**: Reference — alternative routing strategy
+**Status**: Reference (not currently in the hot path)
+**Date**: 2026-03-30

-Live routing uses **rendezvous (HRW) hashing** in
-`turnstone/core/rendezvous.py` and `turnstone/console/router.py`.  This
-document captures a vnode-ring approach as a reference for future
-evaluation if the cluster outgrows rendezvous's O(N)-per-route
-characteristic.
+## Overview

-The FNV-1a-32 hash function specified below is bit-identical to the
-hash used by the live rendezvous implementation; cross-language clients
-can rely on these test vectors.
+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 the ring approach becomes interesting
+## When to consider the ring approach

-The vnode ring becomes preferable to rendezvous hashing when:
+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)

- Cluster size grows large (50+ nodes) and the per-route O(N) hash
-  computation becomes visible against downstream HTTP cost.
- Decentralised routing is needed (each node computes the ring locally,
-  no central console required).
- A precomputed flat-array lookup is desired so the routing hot path
-  avoids hashing entirely.
+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)

-## Per-Model Sampling Overrides
-
-The global `model.temperature`, `model.max_tokens`, and `model.reasoning_effort`
-settings serve as cluster-wide defaults. Individual models can override these
-via per-model settings in the `model_definitions` table (admin Models tab).
-
-Resolution order for sampling parameters:
-
-| Priority | Source |
-|----------|--------|
-| 1 (highest) | Per-model override (set in Models tab) |
-| 2 | Global default (set in Settings tab) |
-| 3 | Registry default (code) |
-
-When a per-model override is `NULL` (empty in the UI), the global default is
-used. Switching models via `/model <alias>` re-resolves sampling parameters
-from the new model's overrides or global defaults.
-
-**Removed settings:** `model.name` and `model.context_window` have been removed
-from ConfigStore. Model names and context windows are now configured per-model
-in the Models tab. A startup warning is logged if these keys appear in
-`config.toml`.
-
-### Plan / task agent overrides
-
-`plan_agent` and `task_agent` sub-sessions resolve independently from the
-conversation model so operators can pick a cheaper/faster model for
-autonomous loops:
-
-| Setting | Purpose |
-|---------|---------|
-| `model.plan_alias` | Alias used for `plan_agent` sub-sessions. Falls back to `[model].plan_model` in config.toml, then `[model].agent_model`, then the session's active model. |
-| `model.task_alias` | Alias used for `task_agent` sub-sessions. Same fallback chain as `plan_alias`. |
-| `model.plan_effort` | Reasoning effort for `plan_agent` (`none` / `minimal` / `low` / `medium` / `high` / `xhigh` / `max`). Defaults to `high`. |
-| `model.task_effort` | Reasoning effort for `task_agent`. Empty string means "inherit from the session". |
-

-next sub-agent invocation — no restart required.

 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.

-> [!NOTE]
-> **Superseded by the built-in coordinator workstream in Turnstone 1.5.**
->
-> This MCP side-car is the pre-1.5 pattern for cluster-wide orchestration.
-> Turnstone 1.5 promotes coordinator behaviour to a first-class workstream
-> kind hosted inside `turnstone-console` — no external MCP server to
-> install or operate, proper per-user audit attribution, and a dedicated
-> UI at `/coordinator/{ws_id}`.
->
-> The extension continues to work for 1.4-and-earlier clusters. On 1.5+:
-> grant the `admin.coordinator` permission, set `coordinator.model_alias`
-> in the admin Settings tab, and create sessions via the dashboard's
-> "new coordinator" button or `POST /v1/api/coordinator/new`. Full
-> removal of this example (including docker / compose references) is
-> planned once 1.5 is confirmed in production.
->
-> | Concern | Built-in coordinator (1.5+) | This MCP extension (1.4-and-earlier) |
-> |---|---|---|
-> | Install | None — shipped in-tree | `pip install -e examples/mcp-cluster-ops` + MCP client config |
-> | Auth | Real creator's `user_id` + `admin.coordinator` permission | Shared service token |
-> | Audit | `coordinator.create` / `close` / `cancel` events on the console; `src="coordinator"` preserved on upstream hops | Service identity only |
-> | UI | `/coordinator/{ws_id}` one-pane HTML | No UI — model-only |
-> | Tool approvals | Inline approval bar in the coordinator pane | MCP approval flow |
-> | Configuration | `coordinator.model_alias`, `coordinator.max_active`, `coordinator.reasoning_effort`, `coordinator.session_jwt_ttl_seconds` | MCP server config file |
->
-> Minimal 1.5 migration:
->
-> ```bash
-> curl -X POST https://console.example/v1/api/coordinator/new \
->   -H "Authorization: Bearer $TOKEN" \
->   -H "Content-Type: application/json" \
->   -d '{"name":"planner","initial_message":"Spawn a worker to check the build"}'
-> ```
->
-> The response carries `ws_id`; open
-> `https://console.example/coordinator/{ws_id}` to watch the session.

 ## How it works

 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 rendezvous routing proxy, returning `ws_id` and `node_url`.
+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.

Patrick Buckley	fed5b96a6f	fix: universal tool_call/tool_result orphan detection for OpenAI-comp… (#346 ) * fix: universal tool_call/tool_result orphan detection for OpenAI-compat providers The Anthropic provider had orphan detection for mismatched tool_call ↔ tool_result pairs, but OpenAI-compatible providers (Chat Completions, Google, Responses API) had none. When an Anthropic model runs behind an OpenAI-compat API (e.g. Azure) or cancellation creates orphans, the API rejects the malformed request. - Rewrite sanitize_messages() with orphan detection: synthesize error tool results for unmatched tool_calls, drop tool results with no matching tool_call, fill empty tool_call IDs with positional remap - Call sanitize_messages() from Responses API _convert_messages() * fix: address review feedback on orphan detection - Track answered IDs per-turn (local_answered) instead of scanning all of out, preventing false matches from reused IDs across turns - Drop empty-ID tool results that have no remap entry instead of passing them through with invalid empty tool_call_id - Increment empty_result_idx for every empty result, not just remapped - Remove dead result_ids peek-ahead code - Add test for repeated tool_call IDs across turns	2026-04-12 20:41:28 -07:00
Patrick Buckley	4a65535e00	fix: accurate token usage tracking for compaction across all providers (#345 ) * fix: accurate token usage tracking for compaction across all providers Anthropic's input_tokens excluded cached tokens, causing massive under-reporting (e.g. 327 vs 9000 actual) when prompt caching was active. This prevented auto-compaction from triggering. - Normalize Anthropic prompt_tokens to total input (input_tokens + cache_creation + cache_read), matching OpenAI semantics - Reset _last_usage per API call so tool-chain iterations get fresh usage instead of max()-merging with stale values - Add mid-turn compaction check during tool chains to prevent context overflow before end-of-turn - Anchor _remaining_token_budget() on provider-reported prompt_tokens with local estimates only for the delta since last API call - Improve _msg_char_count() to include structural overhead (role, tool_call_id, tool call IDs) and handle image tokens in calibration - Emit status after every API call, not just end of turn * fix: defensive null coercion and index clamping from review feedback - Add `or 0` to all getattr calls for input_tokens/output_tokens in Anthropic provider (streaming + non-streaming) to handle SDK nulls - Use getattr for non-streaming input_tokens/output_tokens instead of direct attribute access for consistency - Clamp _calibrated_msg_count with min() in _remaining_token_budget() to prevent stale state from over-slicing after compaction	2026-04-12 20:41:28 -07:00

Patrick Buckley	024a2e98d2	fix(ui): remove broken hint animation and restore card toggle The ws-check-hint animation clobbered the fadein's forwards fill, making the checkbox invisible for 0.6s on card-body click — appearing as a deselect-then-reselect. Remove the hint, the unused role=checkbox on the card, and restore the original symmetric toggle behavior.	2026-04-08 18:05:41 -07:00
Patrick Buckley	e9c141aba5	fix(ui): improve delete workstream UX and accessibility (#339 ) * fix(ui): improve delete workstream UX and accessibility Card body click no longer deselects (prevents confusing red border loss); checkbox pulse hint guides users to deselect affordance. Adds keyboard navigation, aria-labels, hover feedback, animations, and neutral Close button styling after deletion. * fix(ui): remove duplicate a11y checkbox from delete-mode cards Hide the visual checkbox from the a11y tree and tab order so the card (role=checkbox) is the sole keyboard/screen-reader target. Addresses Copilot review feedback about nested interactive elements.	2026-04-08 17:20:45 -07:00
