chore: bump version to 1.3.1

feat: add Claude Opus 4.7 support (#357 )
- Add claude-opus-4-7 capability entry (1M ctx, 128K output, adaptive thinking, supports_temperature=False, thinking_display=summarized) - Suppress temperature param for Opus 4.7 (API returns 400) - Add thinking display opt-in via new ModelCapabilities.thinking_display field - Opus 4.7 omits thinking by default, always send summarized - Add xhigh effort level to mapping and Opus 4.7 effort_levels - Add xhigh/max options to skill template dropdowns in admin console - Align reasoning effort label capitalization across all console dropdowns - Update example config to reference claude-opus-4-7 - 10 new tests with regression guards for Opus 4.6 backward compat Verified against live API: streaming and completion calls succeed. (cherry picked from commit 30c89f46c6)

 ## 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.

-## 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"},
-    "2": {"ws_id": "f1a2b3...", "name": "xss-audit",  "node_id": "gpu-1"}
-  },
-  "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.
-
---

- **Phase 6** shipped `cluster/ws/live` as the first Shape A endpoint
-  (`{results, denied, truncated}`).
- **Phase 7** shipped `stop_cascade` as the first Shape B endpoint
-  (`{cancelled, failed, skipped}`).
- **Phase 8 PR A** shipped `spawn_batch` (Shape A, keyed by idx) and
-  `close_all_children` (Shape B, twin of `stop_cascade`), which
-  crystallised the two-shape-per-semantic-category policy codified
-  here.

-## 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.

-`/history`, `/open`, `/close`, etc.) work on both kinds.

-## 1. Create a coordinator
-
-```http
-POST /v1/api/workstreams/new
-Content-Type: application/json
-Authorization: Bearer <token>
-
-{
-  "name": "release-coord",
-  "skill": "engineer-orchestrator",
-  "initial_message": "audit /auth for CSRF handling across all active routes"
-}
-```
-
-```http
-HTTP/1.1 201 Created
-Content-Type: application/json
-
-{"ws_id": "a1b2c3d4e5f6...", "name": "release-coord"}
-```
-
-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/workstreams/{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` |
-| `stream_end`        | End of a single provider stream                                                            | — |
-| `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` |
-| `intent_verdict`    | Intent judge produced a verdict on a pending tool call                                     | `risk_level`, `recommendation`, `reasons` |
-| `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` |
-| `child_ws_rename`   | A direct child's name changed                                                              | `child_ws_id`, `name` |
-| `wait_started` / `wait_progress` / `wait_ended` | `wait_for_workstream` tool lifecycle (see §6)                  | `call_id`, `ws_ids`, `elapsed`, `results`, `complete` |
-| `batch_started` / `batch_ended` | `spawn_batch` / `close_all_children` tool lifecycle                            | `call_id`, `op`, `total`/`succeeded`/`denied`/`closed`/`failed`/`skipped` |
-| `info` / `error`    | Operational messages                                                                       | `message` |
-
-**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/workstreams/{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/workstreams/{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
-
-```http
-POST /v1/api/workstreams/{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
-
-```http
-POST /v1/api/workstreams/{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
-
-```http
-POST /v1/api/workstreams/{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
-
-```http
-POST /v1/api/workstreams/{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.
-
-```http
-POST /v1/api/workstreams/{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`:
-
-```http
-POST /v1/api/workstreams/{ws_id}/cancel
-{}
-```
-
---
-
-## 9. Close
-
-```http
-POST /v1/api/workstreams/{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/workstreams/{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.                        |
-| `close_workstream`        | wind-down       | Soft-close one child.  Requires approval.                           |
-| `close_all_children`      | wind-down       | Soft-close every direct child in one approval.  Partial-success shape. |
-| `cancel_workstream`       | wind-down       | Drop the in-flight generation; leaves child idle for a fresh send.  |
-| `delete_workstream`       | wind-down       | Hard-delete one child.  Requires approval.                          |
-| `list_nodes`              | discover        | Enumerate live cluster nodes + capabilities.                        |
-| `list_skills`             | discover        | Coordinator-visible skills only (SkillKind filter above).           |
-| `tasks`                   | plan            | Orchestrator-only scratchpad.  Children don't see it.               |
-
-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.
-
---
-
-## `tasks` integration
-
-`tasks` 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
-`tasks(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
-`tasks(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": "<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": "...", "routing_strategy": "..."}`; 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.
-
-```
-tasks(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
-tasks(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.
-
-```
-tasks 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
-tasks → 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 `tasks`, 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
-tasks(action='add', title='...') × N   # the plan, visible in the sidebar
-for task in tasks:
-    spawn_workstream(skill=..., initial_message=task.brief)
-    tasks(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)
-    tasks(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
-   the `_seed_children` helper in `tests/_coord_test_helpers.py`
-   (``_seed_children(mgr._adapter, 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 tasks 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)

-description: Use this skill when the user wants to import or migrate conversation history from another LLM chat or coding tool (e.g. ChatGPT, Claude.ai, Cursor, Copilot Chat, Aider, Gemini, a custom JSON export) into Turnstone. The skill teaches Turnstone's destination contracts — workstream identity, the OpenAI-shaped message rows, tool-call/result pairing, provider-fidelity blobs, attachments, and archive-vs-resumable choice — so the agent can map any source format onto them. Trigger phrases: "import my chats", "migrate this transcript into Turnstone", "bring my Claude.ai history over", "load this export as a workstream".
-version: 1.0.0
---
-
-# Importing Conversation History into Turnstone
-
-## Overview
-
-Source formats vary; the destination does not. Your job is to translate whatever the user hands you (JSON dump, ZIP export, scraped HTML, screenshot OCR, raw transcript) into Turnstone's internal shape: **one workstream row** plus an ordered sequence of **conversation rows** in OpenAI message format. This skill documents the destination so you can write a correct mapper for any source.
-
-Two questions to settle with the user before writing anything:
-
-1. **Archive or resumable?** An archive ("saved" workstream — `state="closed"`) is read-only history. A resumable workstream (`state="idle"`) lets the user continue the conversation; this only works cleanly when the source LLM matches a Turnstone-supported provider/model and tool definitions still resolve.
-2. **One workstream per source thread, or merge?** Default to one-to-one unless the user explicitly asks to merge.
-
-Default to **archive** when in doubt — resuming a foreign transcript with mismatched tool schemas or stale provider signatures will fail at the next turn.
-
-## Turnstone Data Model (the destination)
-
-Two tables carry the conversation:
-
-### `workstreams` (one row per imported thread)
-
-| Column | Required | Notes |
-|---|---|---|
-| `ws_id` | yes | 32-char lowercase hex. Auto-generate with `secrets.token_hex(16)` if you don't already have one. **First 4 hex chars are the routing bucket** — see "Identity & Routing" below. |
-| `name` | yes | Short title. Pull from source thread title; fall back to first ~60 chars of first user message. |
-| `state` | yes | `"closed"` for archive, `"idle"` for resumable. Never set `"running"` on import. |
-| `kind` | yes | `"interactive"` for normal threads. Do NOT use `"coordinator"` for imports — that's reserved for cluster-spawned coordinator workstreams. |
-| `parent_ws_id` | no | Leave NULL. Only set if you're importing a coordinator-spawned subtree and re-parenting it; rare. |
-| `user_id` | yes | Owner. Must exist in `users`; importer must know which Turnstone user owns the imported history. |
-| `node_id` | yes (multi-node) | Denormalized cache of the node that owns this `ws_id`'s bucket. Single-node deployments can leave it NULL or set it to the only node. |
-| `alias` | no | Human-typeable short name. Optional; must be unique cluster-wide if set. |
-| `title` | no | Auto-titled later by the LLM; safe to leave NULL on import. |
-| `skill_id`, `skill_version` | yes | Default `""` and `0` unless the source thread was scoped to a Turnstone skill. |
-| `created`, `updated` | yes | ISO8601 strings. Use the source's first/last message timestamps when available. |
-
-### `conversations` (many rows per thread, ordered by `id`/`timestamp`)
-
-| Column | Notes |
-|---|---|
-| `ws_id` | The workstream this row belongs to. |
-| `timestamp` | ISO8601 string. Preserve source timestamps; fall back to monotonically increasing values if unknown. **Order is canonical via `id` (autoincrement), not `timestamp`** — but always insert in conversational order so both agree. |
-| `role` | One of `system`, `user`, `assistant`, `tool`, `developer`. See role mapping below. |
-| `content` | Text. May be NULL for assistant rows that are *only* tool calls. |
-| `tool_name` | Set on `role="tool"` rows (the tool whose result this is). NULL otherwise. |
-| `tool_call_id` | Set on `role="tool"` rows (matches the assistant row's `tool_calls[].id`). NULL otherwise. |
-| `tool_calls` | JSON-encoded list, on `role="assistant"` rows that issued tool calls. OpenAI shape — see "Tool Calls" below. |
-| `provider_data` | JSON blob preserving provider-native content blocks (Anthropic `signature`, Gemini `thought_signature`, etc.). Optional; only matters for **resumable** imports against the same provider. Skip for archives. |
-
-The internal format is **OpenAI-shaped**, even when the source was Anthropic or Gemini. Providers translate at their own API boundary; storage stays uniform.
-
-## Identity & Routing (`ws_id`)
-
- `ws_id` is **32-char lowercase hex** (i.e. `secrets.token_hex(16)`).
- The **routing bucket** is `int(ws_id[:4], 16)` — the first 4 hex chars place this workstream on a specific node via the consistent hash ring.
- For multi-node imports: either insert through the console's routing proxy (which forwards to the owning node), or generate `ws_id`s and write directly to each node's database in batches grouped by bucket.
- For single-node imports: bucket math is irrelevant; any `ws_id` works.
- **Do not reuse the source platform's IDs as `ws_id`** unless they happen to be 32-char hex. Generate fresh; if you need the old ID for traceability, store it in `workstream_config` under a key like `import.source_id`.
-
-## Recommended Import Path
-
-Three options, in order of preference:
-
-### 1. Storage protocol (recommended for full history)
-
-Use `turnstone.core.storage.Storage.save_messages_bulk(rows)`. This is the canonical bulk-insert primitive and bypasses the LLM round-trip entirely.
-
-```python
-from turnstone.core.storage import get_storage  # construct via the same path the server uses
-
-storage = get_storage(...)  # see turnstone.core.storage.__init__ for the project's wiring
-
-storage.create_workstream(  # or whatever the project's exposed creator is — check turnstone/core/storage/_protocol.py
-    ws_id=ws_id,
-    user_id=user_id,
-    name=name,
-    state="closed",
-    kind="interactive",
-    ...
-)
-
-storage.save_messages_bulk([
-    {"ws_id": ws_id, "role": "user", "content": "Hello"},
-    {"ws_id": ws_id, "role": "assistant", "content": "Hi! What can I help with?"},
-    {"ws_id": ws_id, "role": "assistant", "content": None,
-     "tool_calls": json.dumps([{"id": "call_1", "type": "function",
-                                "function": {"name": "search", "arguments": "{\"q\":\"x\"}"}}])},
-    {"ws_id": ws_id, "role": "tool", "tool_name": "search", "tool_call_id": "call_1",
-     "content": "result text"},
-    # ...
-])
-```
-
-`save_messages_bulk` handles `timestamp` and the workstream's `updated` column internally, so you don't need to compute them per row. **Verify the exact creator signature** by reading `turnstone/core/storage/_protocol.py` — table layout has shifted across migrations and the Storage protocol is the source of truth.
-
-### 2. SDK `create_workstream(resume_ws=...)` (when the source is already a Turnstone workstream)
-
-Only useful for *Turnstone → Turnstone* re-parenting. Not relevant for foreign sources.
-
-### 3. SDK `create_workstream(initial_message=...)` + `send()` per turn (last resort)
-
-Only fits archives where the source had **no tool calls** and you don't care about preserving assistant turns verbatim. Each `send()` triggers a real LLM round-trip, which is expensive and rewrites assistant content. Don't use this for full history.
-
-## Role Mapping
-
-Common source-role conventions and how they map to Turnstone:
-
-| Source role | Turnstone `role` | Notes |
-|---|---|---|
-| `user`, `human` | `user` | Direct map. |
-| `assistant`, `ai`, `model`, `bot` | `assistant` | Direct map. |
-| `system` | `system` | Preserve only if it's content the user wrote (custom instructions). Drop boilerplate provider preambles — Turnstone composes its own system message. |
-| `developer` (OpenAI o-series) | `developer` | Preserve. |
-| `tool`, `function`, `tool_result` | `tool` | Must carry `tool_name` and `tool_call_id` matching the prior assistant row's `tool_calls[].id`. |
-| `tool_use` (Anthropic) | `assistant` with `tool_calls` | Anthropic emits tool calls *inside* an assistant message; flatten to OpenAI shape. |
-| `human_feedback`, `revision` | `user` | Treat as a follow-up user turn. |
-
-## Tool Calls (the most error-prone part)
-
-Turnstone stores tool calls in OpenAI's nested-function shape on the assistant row, and matches them with `role="tool"` result rows by `tool_call_id`.
-
-### Assistant row with tool calls
-
-```json
-{
-  "role": "assistant",
-  "content": null,
-  "tool_calls": [
-    {
-      "id": "call_abc123",
-      "type": "function",
-      "function": {
-        "name": "search_web",
-        "arguments": "{\"query\":\"turnstone import\"}"
-      }
-    }
-  ]
-}
-```
-
-`tool_calls[].function.arguments` is **a JSON-encoded string**, not an object. Source formats commonly get this wrong — Anthropic stores arguments as a parsed object, Gemini as a struct. Always re-serialize to a string.
-
-### Tool result row
-
-```json
-{
-  "role": "tool",
-  "tool_name": "search_web",
-  "tool_call_id": "call_abc123",
-  "content": "..."
-}
-```
-
-Pairing rules:
- Every assistant `tool_calls[].id` MUST be followed by exactly one `role="tool"` row with the matching `tool_call_id`, before the next user/assistant turn.
- If the source dropped the tool result (cut-off transcript), insert a synthetic `role="tool"` row with `content="[tool result missing in source]"` to keep the chain valid. An assistant row with an unanswered `tool_calls[].id` will break replay and any LLM round-trip.
- Multi-tool assistant turns: one `role="tool"` row per call, in any order, all before the next non-tool row.
-
-### Tool ID generation
-
-If the source used opaque tool IDs that aren't unique within a thread (some platforms reuse them), regenerate with a stable scheme like `f"call_{i}"` where `i` is a per-thread counter. Update both the assistant and tool rows together.
-
-## Provider Fidelity (`provider_data`)
-
-Skip this entirely for **archive** imports.
-
-For **resumable** imports against the same provider, populate `provider_data` to preserve provider-specific tool-call metadata that the next API round-trip will require:
-
- **Anthropic**: `signature` field on thinking blocks; required for round-tripping extended-thinking responses.
- **Gemini**: `thought_signature` on tool calls; required for fidelity.
- **OpenAI**: typically nothing to preserve.
-
-The runtime-side dict key is `_provider_content` (a list of provider-native blocks); the persisted column is `provider_data` (the same list, JSON-encoded). If you don't have provider-native blocks from the source — and you usually won't, because a foreign export won't include them — leave `provider_data` NULL. The first new turn will succeed without it, but the previous assistant turn's reasoning won't replay back to the model.
-
-## Attachments
-
-If the source thread had image or file attachments:
-
- **Size limits**: images ≤ 4 MiB, text documents ≤ 512 KiB. Reject or downsample anything bigger.
- **Allowed types**: server validates magic bytes for images and UTF-8-decodes for text. Binary blobs that aren't images won't pass.
- **Lifecycle**: pending → reserved → consumed. For imports, the cleanest path is to upload as pending and immediately consume by attaching to the relevant `conversations.id`.
-
-Two import paths:
-
-1. **Bulk-insert + post-attach**: insert messages first, get back the assistant/user `conversations.id`, then write `workstream_attachments` rows linking the file to `message_id`.
-2. **SDK multipart create**: `create_workstream(attachments=[...], initial_message=...)` for the *first* turn only — the server reserves and consumes them onto that turn. Doesn't help for mid-thread attachments.
-
-For full-history imports with multiple attachments at different turns, path (1) is the only option.
-
-## Validation Checklist
-
-Before declaring success, verify:
-
- [ ] `ws_id` is 32-char lowercase hex.
- [ ] `workstreams` row exists with the right `user_id`, `state`, `kind`.
- [ ] Conversation rows are inserted **in order** (autoincrement `id` will reflect insert order).
- [ ] Every assistant `tool_calls[].id` has a matching `role="tool"` row with the same `tool_call_id`.
- [ ] `tool_calls[].function.arguments` is a JSON-encoded **string**, not a parsed object.
- [ ] First message is typically `role="user"` (not `system`) — Turnstone composes its own system prompt at runtime.
- [ ] No empty assistant rows (`content=NULL` AND `tool_calls=NULL` is invalid).
- [ ] If multi-node: the `ws_id`'s bucket maps to a node that exists; `workstreams.node_id` matches.
- [ ] Round-trip test: run `Storage.load_messages(ws_id)` and confirm the reconstructed list matches what you inserted (modulo timestamps).
-
-## Anti-patterns
-
- **Don't import the source provider's system prompt verbatim.** Provider boilerplate ("You are Claude...", "You are ChatGPT...") will conflict with Turnstone's composed system message and confuse the model on resume. Drop it; preserve only user-authored custom instructions.
- **Don't preserve foreign tool definitions as Turnstone tools.** If the source had custom tools that don't exist in Turnstone, the assistant rows that called them are still valid history (archive), but the workstream is **not resumable** — mark `state="closed"`.
- **Don't fabricate `tool_call_id`s without re-pairing.** Mismatched ids silently break the replay chain on the next turn.
- **Don't skip the `tool_name` field on `role="tool"` rows.** Some load paths use it for display and audit; NULL there will render as "unknown tool".
- **Don't write through the LLM (`send()` per turn) for full history.** It's expensive, rewrites assistant turns, and rate-limits will bite long imports.
-

-## Files to read before writing the importer
-
- `turnstone/core/storage/_schema.py` — authoritative table definitions.
- `turnstone/core/storage/_protocol.py` — `save_message`, `save_messages_bulk`, `load_messages` signatures.
- `turnstone/core/session.py` (around the message-save section) — how the runtime constructs in-memory message dicts; mirror this shape on import to round-trip cleanly.
- `turnstone/api/server_schemas.py` — Pydantic shapes for the SDK paths if you go through HTTP.

 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 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.

-to ``SessionUIBase`` automatically enables:
-
- Tool-policy gating now applies to coord tool calls (was interactive-only).
- Heuristic verdicts persist on coord (was interactive-only).
- The activity tag fields populate on coord during pending approval.
- ``judge_pending`` is dynamic on the coord ``approve_request``
-  (was hardcoded ``False``).
- The auto-approve fall-through emits ``tool_info`` (was
-  ``tools_auto_approved``).
- ``_record_judge_metric`` is a no-op on coord (no Prometheus on console).
