* refactor(session): make ModelLane the provider boundary (#979)

## Summary

This closes the model-lane ownership gap left by #832: `ChatSession` no longer stores raw provider/client handles. `ResolvedModelBinding` now carries the provider, client, model, capabilities, registry generation, and backend-auth configuration as one coherent snapshot.

- Atomically rebind existing sessions after model-registry changes while pinning each in-flight send, fallback, judge, output guard, task agent, title, compaction, perception, and voice operation to its initiating principal and binding.
- Fence UI publication, canonical trajectory folds, durable writes, streams, retries, child scopes, and judge work by generation. Stop can hand off to a successor without accepting late state; cancelled tools retain typed effect receipts, and concurrent approval batches resolve by exact cycle or call.
- Make create, fork, open, close, and delete race-safe with hidden `creating` reservations, incarnation-aware state tails, and an ACL-rechecked transaction that clones checkpoint-bounded history, configuration, project/persona state, and attachment references.
- Extend REST/OpenAPI and Python/TypeScript SDK contracts for create/fork inputs, routed-create metadata, live-workstream probes, targeted approvals, and structured cancellation results.
- Update architecture, storage, authentication, judge, channel, console, API, and SDK documentation, including regenerated architecture diagrams and OpenAPI artifacts.

## Validation

- SQLite suite: 11,188 passed, 9 skipped, 10 deselected
- PostgreSQL suite: 11,195 passed, 2 skipped, 10 deselected
- Live backend: 3 passed
- SSE recovery: 6 passed; browser recovery harness passed all scenarios
- Ruff: clean; 595 files correctly formatted
- mypy: 243 source files clean
- TypeScript: typecheck/build and 35 tests passed
- OpenAPI artifacts fresh; all 14 changed diagrams reproduce byte-for-byte
- `git diff --check` and Git LFS integrity clean

Closes #979.

* fix(deps): update nanoid for GHSA-2v37-7h3g-55p8

Refresh the transitive lock entry admitted by PostCSS so the TypeScript security gate no longer resolves the vulnerable custom-generator implementation.

Validation:
- npm ci
- npm audit --audit-level=moderate: 0 vulnerabilities
- TypeScript typecheck and build
- TypeScript tests: 35 passed

* fix(test): assert canonical model registry URLs

Replace prefix checks with exact canonical base URL assertions so the tests do not model incomplete URL validation.

Validation: tests/test_model_registry.py (185 passed); Ruff check/format; mypy.

### `POST /v1/api/workstreams/{ws_id}/cancel`
Cancels the active generation in a workstream. Sets a cooperative cancellation
flag that is checked at multiple points in the generation loop (per streaming
chunk, before tool execution, inside bash commands). Also closes the underlying
HTTP stream to the LLM provider, unblocking any pending read immediately.
The session transitions to `idle` state and preserves any partial content
already streamed.
Cancels the workstream's current generation. Stop propagates to the primary or
fallback model stream, model-backed attachment processing, parallel task-agent
and foreground tool model calls, intent and output-guard judges, tracked bash
subprocesses, and every approval cycle owned by that generation. Pending plan
review is rejected as well. The worker preserves any assistant content already
streamed and synthesizes honest cancelled tool results where needed so the
saved conversation remains replayable.
If the workstream is waiting for tool approval or plan review, the pending
prompt is automatically denied/rejected to unblock the worker thread.
The cooperative response is immediate: `status: ok` acknowledges the request,
not completion. A running workstream emits `cancelled`, then transitions to
`idle` after its worker unwinds. Depending on where Stop arrived,
`stream_end` may have been emitted before the cancel request or may arrive while
the worker is unwinding; clients use the terminal `state_change`, not
`stream_end`, to become ready. An idle cancel is a harmless no-op and emits no
misleading cancellation event. Detached background shells and watches are
independent resources and are not stopped by this endpoint.
Calling this endpoint when the workstream is already idle is a harmless no-op.
**Force cancel:** When `force` is `true`, the server abandons the stuck worker
thread immediately and transitions the workstream to `idle`. The abandoned
thread continues to wind down in the background (killing any running
subprocesses and exiting at the next cancellation checkpoint). During this
wind-down it may emit a final `stream_end` event which the server suppresses
for the orphaned thread. Use force cancel when cooperative cancel has not
resolved within a few seconds — the web UI offers this as a "Force Stop"
button automatically.
**Force cancel:** When `force` is `true`, the server releases the stuck worker

The abandoned daemon still owns its already-started external effects until it

history and UI publication, but quick slash-command workers do not yet have
generation checkpoints and may finish an in-place mutation concurrently with a
successor. Use force cancel only when cooperative cancellation has not resolved

#### Fork behavior (`resume_ws`)
Despite the compatibility field name, `resume_ws` does not reopen or move the
source workstream. It creates a distinct destination ID and atomically clones
the source's checkpoint-bounded conversation, saved session configuration,
persona, effective project, and attachment references. The source remains
unchanged. Use `POST .../{ws_id}/open` when you want to rehydrate the original
ID instead.
The clone transaction rechecks source visibility, private-project membership
and attachability, persona/project construction context, destination ownership
and emptiness, and attachment integrity. A caller cannot use `project_id` to
re-file or declassify the fork. Uploads cannot be combined with `resume_ws`;
fork first, then use the ordinary attachment endpoint. Concurrent source-history
writes serialize wholly before or after the clone snapshot; access,
construction-context, or destination conflicts fail the whole fork rather than
publishing a mixed result.
#### Publication and rollback
Creation first reserves the ID durably with internal state `creating`. That
reservation is hidden from list, saved, resolve, open, and cluster-event
surfaces while the session is constructed, uploads are validated, and an
optional fork transaction commits. The final durable `creating` to `idle`
compare-and-set happens before `ws_created`, audit, initial-message dispatch,
or any state event. A normal pre-publication failure immediately and
conditionally deletes the exact token-bearing reservation and emits no
lifecycle event; if cleanup itself fails, the original HTTP error is retained
and `ws.create.rollback_failed` is logged, leaving the row hidden rather than
advertising a half-create.
Long-lived server and console processes also run hidden-reservation recovery at
boot and every five minutes, independently of ordinary idle eviction. It only
considers rows still in internal `state='creating'` and older than two hours,
excluding IDs currently loaded or pending in the manager. A live remote owner
protects its rows; the current process's stable node ID does not self-protect,
so a restart can recover its predecessor's residue. Failure to establish
service liveness, or a storage failure, deletes nothing. Eligible rows are
atomically hard-deleted with their dependent records and attachment refcounts;
an eligible tokenless legacy or corrupt reservation is locked, recovered, and
logged as a warning. Retention pruning leaves `creating` rows to this path. The
value is not a live `WorkstreamState`, and recovery neither publishes nor
closes it.

On reconnect, the server replays the full conversation history via the

same reconnection strategy applies to both the per-workstream SSE stream
(`/v1/api/workstreams/{ws_id}/events`) and the global state stream (`/v1/api/events/global`).
Per-workstream events carry monotonic SSE IDs and are retained in a bounded
ring. Native `Last-Event-ID` and the `?last_event_id=N` query fallback both
resume after the last applied event. If the ring covers the gap, only missing
events are replayed. If it does not, the server emits:

| `ws_id` | Optional 32-hex destination. When present, it is preserved and used as the rendezvous key, including on a fork. A 503 never replaces a caller-selected ID. |
| `resume_ws` | Optional source ID or saved alias for an atomic fork. The console resolves aliases to the canonical source ID before routing and forwards that canonical value. When no destination `ws_id` is supplied, the source is the placement key. |
| `target_node` | Optional node ID hint. When neither `ws_id` nor `resume_ws` selects placement, the console generates a destination whose rendezvous owner is this live node. |
Proxy a message to the workstream's assigned server node.
Without any placement field, the console generates a destination ID and routes
it by rendezvous. Multipart callers must pre-allocate the destination and put
the **same** 32-hex value in both `?ws_id=<32-hex>` and the multipart
`meta.ws_id` field. The query value selects the target node; the console
buffers the body, parses only `meta` to require the same destination ID, then
forwards the original bytes and boundary unchanged. The node uses `meta.ws_id`
as the destination identity.
### `POST /v1/api/route/approve`
The response extends the node create response with three required fields:
`node_url`, authoritative `node_id`, and `routing_strategy`.
`routing_strategy` is `rendezvous` for generated, explicit JSON, and multipart
destination IDs; `target_node` when the console generated an ID for a requested
node; or `resume` only when an atomic fork was placed by its canonical source
ID. The node-returned destination `ws_id` is authoritative for the response,
storage binding lookup, and audit record; the fork source is never reported as
the created destination.
Proxy an approval response to the workstream's assigned server node.
The JSON body must be an object. `ws_id`, `resume_ws`, and `target_node` must be
strings when supplied; malformed placement fields return `400`. A missing fork
source returns the same generic `404` as other missing workstreams. If a node
returns `200` without an object containing a valid destination `ws_id`, the
console returns a bounded `502` instead of exposing or trusting the malformed
payload.
### `POST /v1/api/route/cancel`
### `GET /v1/api/route/workstreams/{ws_id}/live`
Cancel generation on a workstream.
Probe the rendezvous-selected owner without opening or rehydrating the
workstream. The console asks that node's manager-authoritative active list and
returns only:
```json
{"ws_id": "abc123", "live": true}
```
Missing, unloaded, still-`creating`, and caller-invisible workstreams all
produce `live: false`. Routing, upstream, and authorization uncertainty returns
an error instead of a false miss, so callers can preserve an existing route.
### `POST /v1/api/route/workstreams/{ws_id}/send`
Proxy a message to the workstream's assigned server node. `DELETE` on the same
path dequeues a queued send.
### `POST /v1/api/route/workstreams/{ws_id}/approve`
Proxy an approval response, including optional `cycle_id` / `call_id`, to the
workstream's assigned server node.
### `POST /v1/api/route/workstreams/{ws_id}/cancel`
Cancel generation on a workstream. The request and response have the same
`force` / `dropped` shape as the node endpoint.
### `POST /v1/api/route/command`
Send a slash command to a workstream.
Send a conversation-local slash command. This legacy route still takes
`ws_id` in the JSON body.
### `POST /v1/api/route/plan`
### `POST /v1/api/route/workstreams/{ws_id}/{rewind|retry}`
Send plan review feedback to a workstream.
Proxy a dedicated conversation-modification request.
### `POST /v1/api/route/workstreams/close`
### `POST /v1/api/route/workstreams/{ws_id}/close`
Close a workstream.
The console also exposes path-keyed routed attachment endpoints and
`POST /v1/api/route/workstreams/delete` for coordinator-driven hard deletion.
### `GET /v1/api/route?ws_id=X`
Look up which server node owns a workstream. Returns `{"node_url": "...", "node_id": "..."}`.

The response confirms the workstream creation request was proxied to the target node. A `ws_created` event on the cluster SSE stream confirms the workstream was actually created.
The response is returned only after the target node has durably published the
workstream. Its hidden `creating` reservation has already crossed to `idle`,
and the node emitted `ws_created` before any initial-message state event. The
cluster SSE event may therefore arrive before or after the HTTP response;
clients should reconcile both by the returned `correlation_id`/workstream ID
rather than treating them as two creates.
For safety, the console masks most target-node failures as the opaque `502`
shape `{"error":"Dispatch to node <node_id> failed"}` instead of reflecting
arbitrary node text or retry-triggering 401/429 responses. The coded
`server.require_project` refusal is the exception and remains a `400` with
actionable wording. Consult the target node's logs for the underlying create
correlation when a reachable node returns a masked 502.

## Browser Dashboard
The web UI has five views, toggled client-side:
The console uses an L-shaped application shell: a collapsible navigation rail,
a tab bar, and a pane host. On mobile the rail becomes an off-canvas drawer.
The rail is fed by the cluster SSE snapshot and shows:
### 1. Cluster Overview (landing)
- state/count filters and the live compute-node list, including version drift;
- active coordinator and interactive workstreams, nested under their
coordinator parent and grouped by project when project metadata is visible;
- permission-filtered Manage groups that open the singleton Admin pane.
- **State cards** — 5 clickable cards (running, thinking, attention, idle, error) with count and colored top border. Clicking filters to that state.
- **Aggregate bar** — total tokens and tool calls across the cluster.
- **Node table** — columns: NODE, WS, RUN, ATTN, TOKENS, VER, LOAD. Sorted by activity. Clickable rows drill down to node detail. Version column shows per-node version; hidden on mobile.
- **Version drift indicator** — when nodes report different versions, the status bar shows a yellow "DRIFT" warning with a tooltip listing all versions. Node groups show "mixed" with a yellow badge when their members disagree.
- **"+ new" button** — opens the workstream creation modal (see below).
Coordinator and interactive conversations open as tabs inside the same shell.
Interactive panes use the owning node's console proxy, so users do not need
direct network access to compute-node ports. Split-right and split-down actions
can display several panes at once. Closing a pane removes only that tab; use the
pane menu's explicit close or delete action to change the workstream lifecycle.
### 2. Node Drill-down
### Dashboard pane
Breadcrumb: `Cluster > db-west-04`. Shows the node's workstreams in a table matching the per-node dashboard layout (STATE, NAME, MODEL, NODE, TASK, TOKENS, CTX) with activity sub-lines. Includes a link to the node's proxied server UI.
The home view is coordinator-first. It contains the persistent workstream
launcher plus the saved-sessions list. Selecting a state count opens the
filtered workstream table inside the same Dashboard pane; selecting a compute
node opens its proxied node surface. Cluster SSE updates keep rail state,
workstream rows, and tab state glyphs synchronized.
**Proxy deep-linking:** Clicking a workstream row opens the node's server UI in a new tab via the proxy at `/node/{node_id}/?ws_id=<id>`, which auto-selects that workstream. Users do not need direct network access to the server node.
### Workstream launcher
### 3. Filtered Workstreams
The landing-page composer starts a workstream with an optional initial task and
attachments. When the caller can create both kinds, a Coordinator / Interactive
toggle selects the target kind. Its options include:
Breadcrumb: `Cluster > Running` or `Cluster > db-west-04`. Server-side paginated workstream table. NODE column values are clickable to filter further. Pagination controls at bottom. Workstream rows use proxy deep-links.
### 4. Workstream Creation Modal
Triggered by the "+ new" header button. A modal dialog with:
- **Node selector** — dropdown with three targeting modes: "Auto (best available)" picks the node with the most headroom, "General pool (any node)" picks a node with available capacity using round-robin, or a specific node from the list (showing capacity).
- **Node placement** — "Least loaded" picks the reachable node with the most
headroom, or "Specific node" pins the create to a node from the live list.
- **Persona** — optional dropdown listing the enabled personas for the workstream kind. Sets the system-message composition and capability envelope at creation, snapshotted server-side; empty uses the kind's default. Picking one requires no `persona.*` permission.
- **Profile** — optional dropdown listing enabled skills. Applies the skill's model, auto-approve policy, token budget, and other behavioral settings at creation time.
- **Skill** — optional dropdown listing enabled skills. Applies the skill's model, auto-approve policy, token budget, and other behavioral settings at creation time.
- **Project** — optional project filing. Private projects require owner/member access. A coordinator child inherits its parent's project unless explicitly routed to another attachable project.
- **Name** — optional text input. Auto-generated if left empty.
- **Model** — optional text input for a model alias from the target node's registry.
- **Judge Model** — optional text input for the judge model alias (overrides the default judge model for this workstream).
- **Model** — optional selector populated from the target model registry.
- **Judge Model** — optional selector for the judge alias (overrides the default
judge model for this workstream).
Keyboard shortcuts: Ctrl+Shift+R (refresh title), Ctrl+Shift+E (edit title), Ctrl+Shift+F (fork), Ctrl+Shift+X (delete). Press ? for full shortcut help.
Interactive launches additionally expose node strategy / node selection.
Submitting uses `POST /v1/api/cluster/workstreams/new`; coordinator launches use
the console's coordinator create surface. A toast confirms the committed
create, while SSE updates the dashboard and opens the resulting pane.
On submit, `POST /v1/api/cluster/workstreams/new` dispatches the creation request. A toast confirms success; the SSE stream delivers the `ws_created` event to update the dashboard.
Files require a non-empty initial task so the first turn consumes the staged
attachments. The console shell does not currently expose a fork action; use the
node's standalone workstream UI or the create API's `resume_ws` field.
All five views receive live updates via SSE — state cards update counts, node rows update metrics, workstream rows update state indicators.
### Saved and filtered sessions
The browser maintains a local `clusterState` object that mirrors the cluster snapshot. It is initialized from the SSE `snapshot` event on connect (or via `GET /v1/api/cluster/snapshot` on initial page load) and updated incrementally by SSE events. View navigation reads from local state — no API round-trips needed after the initial snapshot.
Saved coordinator and interactive sessions share one list with kind and persona
labels, filtering, pagination, and multi-select deletion. Opening a saved
coordinator rehydrates it in the console; opening a saved interactive session
resolves its node, calls `open`, and then connects the node-proxied pane.
### 5. Admin Panel
The filtered live table carries STATE, NAME, MODEL, NODE, TASK, TOKENS, and CTX
columns. The browser maintains a local `clusterState` initialized from the
cluster snapshot and updated incrementally by SSE; the filtered view normally
renders from that state without another API round trip.

**Cancel escalation:**
1. **Cooperative**: cancel() sets event + closes
SDK stream → worker exits at next checkpoint
2. **Force**: force=true abandons the worker
thread, emits stream_end immediately.
Orphaned thread still kills subprocesses
but skips message mutations (generation
counter prevents stale writes).
**Generation-scoped Stop:**
• Sets the active generation event.
• Closes its SDK stream; aborts child model
scopes and judges; kills subprocess groups.
• Sweeps every approval cycle owned by the
cancelled workstream operation.
• Every later send/model live or durable commit
re-checks generation ownership.
**force=true:** also abandons the stuck worker
slot and emits stream_end + IDLE immediately.
An orphaned send/model generation may unwind
but cannot publish into a successor generation.
Quick slash-command workers are a best-effort
escape hatch: without generation checkpoints,
one may finish an in-place mutation concurrently.
**Capacity eviction:** an IDLE candidate is only
a hint. Per-ID + object lifecycle lanes and the
workstream lock revalidate it as worker- and
send-barrier-free,
then install a terminal claim before slot swap.
end note
note right of thinking
**Emitted via:**
session._emit_state(state)
→ ui.on_state_change(state)
→ SessionManager state tail
**Propagation:**
• WebUI → global SSE queue (ws_state)
• Console → HTTP polling picks up state
• CLI → WorkstreamManager.set_state()
• Console → cluster event / HTTP state
• CLI → SessionManager.set_state()
Non-terminal persistence may use StateWriter;
a per-id tail orders storage + subscribers and
prevents a late state from overwriting CLOSED.
end note
note left of attention
**Blocking mechanisms:**
• TerminalUI: input() prompt
• WebUI: threading.Event.wait()
• WebUI: one Event per ApprovalCycle
• ChannelBot: SSE event + Discord button
• NullUI: auto-approve (never reaches)
end note
note right of creating
CREATING and CLOSED are storage lifecycle
values, not members of WorkstreamState. The
live enum remains IDLE / THINKING / RUNNING /
ATTENTION / ERROR.
**Crash-abandoned CREATING recovery:**
• Boot pass, then every 5 min even when idle
eviction is disabled.
• Only rows >2h old; manager loaded/pending
IDs and live remote owners are protected.
• The current stable node ID is not a live-owner
exemption, allowing restart recovery.
• Unknown liveness/storage fails closed. Deletion
is atomic across dependents and attachment refs.
• Tokenless legacy/corrupt rows are locked,
reaped, and logged with a warning.
A loaded hard delete closes publication, drains
admitted session durability + state tails, then
conditionally removes the exact durable token.

Any normal prepublication failure immediately calls exact token-checked
deletion. The token survives publication as the row's incarnation fence:
rollback or later hard delete can never ABA-delete a replacement row.
A legacy row acquires the same private token atomically when rehydrate,
delete, or fork preflight takes its authoritative snapshot. Loaded hard
delete drains admitted session durability before its token-checked delete.

**Crash-abandoned hidden-create recovery**
• Boot pass; long-lived processes repeat every 5 min,
even when ordinary idle eviction is disabled.
• Candidates remain state="creating", are >2h old,
and are absent from the manager loaded/pending set.
• Live remote owners are protected. The current stable
node ID does not self-protect, enabling restart recovery.
• Unknown liveness or storage failure deletes nothing.
• One transaction rechecks state, age, and token, then
hard-deletes dependents and releases attachment refs.
• Tokenless legacy/corrupt rows use their locked durable
row as the incarnation fence and log a warning.
• Retention pruning excludes creating rows. Recovery never
closes or publishes them as live WorkstreamState values.
end note
note bottom of PG
Production backend.
Multi-node / Docker default.
Use PgBouncer (transaction mode)
for clusters > 50 nodes.
note bottom of Utils
**Atomic fork clone**
• Reject a provisional source; compare the source incarnation captured
by canonical preflight; re-authorize project visibility and compare the
live session envelope inside the transaction.
• Require a same-owner, empty destination still in creating state
with the exact reservation token.
• Copy the checkpoint-bounded canonical trajectory and config;
retain every referenced attachment or roll everything back.
• Preserve/rebase a valid compaction checkpoint watermark and
return the exact snapshot installed into the live destination.
end note
note bottom of Conversations
Full transcript rows are never deleted by compaction. Normal resume
loads the latest valid [summary] + rows after its watermark; audit and
export can request the full marker-free history.

AuthMiddleware on every request:

2. Detect type (JWT / ts_ / config)
3. Validate → AuthResult
4. Set ctx_user_id for logging
5. Store auth_result in scope state
note right of Resolver
**Mode policy**
• static: return None; registry client's explicit key remains.
• entra_obo / rfc8693_obo: require an effective principal. HTTP
turns pin the authenticated initiator; single-user internal lanes
may use their session owner. Never borrow another generation's identity.
• entra_app: use deployment app identity, no user required.
• rfc8693_obo alone sends obo_scopes; each dynamic mode is paired
with its required Entra or RFC 8693 grant profile.
end note
note bottom of SH
**Console** owns admin endpoints
**Server** validates JWT + config only
Both share JWT signing secret
note bottom of CallClient
Dynamic credentials are minted at dispatch, not cached in the registry
snapshot. Endpoint, audience, scopes, auth mode, and static-key presence stay
pinned to the same ModelConfig generation as the SDK client. The global
model.auth_fail_closed policy is read live on every mint. A Stop that wins
before or during mint prevents model bytes from being sent afterward.
end note
note left of JWT
**Console Proxy Token Minting**
When proxying requests to server nodes:
1. Console AuthMiddleware validates user JWT (aud: turnstone-console)
2. Proxy mints new JWT (aud: turnstone-server)
with real user_id, scopes, permissions
3. src: "console-proxy" for audit traceability
4. 5-minute expiry (fresh per request)
5. Fallback: ServiceTokenManager if no user context
note bottom of ProviderCall
If minting fails, a configured fail-closed deployment or a keyless alias
raises BackendAuthUnavailableError. A dynamic alias with an explicit static
key may fall back only when policy allows. Authentication refusal is not a
backend-health failure and does not walk to a static fallback model.

== Tool Call Requires Approval ==
== Intent assessment begins during preparation ==
Session -> Session : _prepare_tool_calls()
note right
Tool calls parsed from
LLM response. Auto-approved
tools dispatched immediately.
Remaining items need approval.
Session -> Session : prepare each tool item independently\nattach principal + cancel witness
Session -> Judge : evaluate(items, callback, cancel_ref)
activate Judge
Judge -> Judge : synchronous heuristic verdict\nfor each call (first matching rule)
Judge --> Session : heuristic verdicts + daemon cancel event
Session -> UI : cache / publish heuristic assessments
Session -> Storage : persist heuristic intent verdicts
note over Judge, Model
The judge owns an immutable resolved binding. Registry/config generations
are freshness watermarks: an effective lane change replaces the judge for
the next batch, while in-flight work keeps the lane it started with.
Dynamic backend auth is resolved for this batch's initiating principal.
end note
Session -> Session : _evaluate_intent(pending_items)
== Tier 1: Heuristic (synchronous, sub-ms) ==
Session -> Judge : evaluate(items, messages, callback)
Judge -> Judge : evaluate_heuristic()\nfor each item
note right
**36 rules (first match wins):**
Critical (0.90, deny): rm /, mkfs,
dd, pipe-to-shell, chmod 777 /,
write/edit /etc/ .ssh/,
download-then-execute chains
High (0.80, review): sudo, kill -9,
destructive git, DROP TABLE,

Medium (0.70, review): content
ingestion, interpreter exec,
cloud CLI mutations, pkg install,
write_file, MCP tools, docker ops
Low (0.85, approve): read_file,
list_directory, search, recall,
tool_search, read_resource,
web_search, read-only bash
Default: medium, 0.50, review
end note
Judge --> Session : heuristic_verdicts[]
Session -> Session : attach _heuristic_verdict\nto each pending item
Session -> UI : SSE: approve_request\n{items: [{verdict: ...}],\n judge_pending: true}
note right
Heuristic verdict displayed
immediately as risk badge.
Spinner shown while LLM
judge evaluates.
end note
Session -> Storage : create_intent_verdict()\nfor each heuristic verdict
== Tier 2: LLM Judge (daemon thread, async) ==
Judge -> Judge : spawn daemon thread\n"intent-judge"
note over Judge, LLM
**Context preparation:**
1. FIFO-truncate conversation history
to max_context_ratio of context window
2. Append tool call details as user message
3. System prompt defines judge role + JSON schema
end note
loop up to 3 turns (timeout budget)

1. Direct JSON.loads
2. Markdown code block
3. Brace-counting
4. Regex field extraction

end
== Tier 3: Arbitration ==
== Policy, Smart Approval, and human gate ==
Judge -> Judge : compare confidence:\nLLM vs heuristic
note right
Only deliver LLM verdict
if confidence > heuristic.
Otherwise heuristic stands.
end note
alt LLM confidence > heuristic confidence
Judge -> Session : callback(llm_verdict)
Session -> UI : SSE: intent_verdict\n{tier: "llm", ...}
note right
UI replaces heuristic badge
with LLM verdict. Spinner
resolves to final assessment.
end note
Session -> Storage : create_intent_verdict()\nfor LLM verdict
UI -> UI : apply explicit policy / skill / always / blanket bypasses
opt Smart Approvals enabled
UI -> UI : wait within captured deadline for this batch's verdicts
UI -> UI : auto-approve only recommendation=approve\nand confidence >= captured threshold
UI -> Storage : persist auto-approval reason and decision
end
== User Decision ==
UI -> Session : resolve_approval(\napproved, feedback)
Session -> Storage : update_intent_verdict(\nverdict_id, user_decision)
note right
All tracked verdicts
(heuristic + LLM) updated
with "approved" or "denied".
Swap-and-clear avoids racing
with daemon judge thread.
end note
== Tool Execution ==
Session -> Session : _execute_tools()
note right
Tools execute with
user approval.
end note
== Output Guard (synchronous, time-budgeted) ==
Session -> Session : _evaluate_output()\nfor each tool result
note right
**Priority-ordered checks (5s budget):**
P1: Prompt injection (role injection,
override phrases, instruction tags)
P2: Credential leakage (API keys,
PEM blocks, connection strings)
P3: Encoded payloads (data URIs,
hex shellcode)
P4: Adversarial URLs (cloud metadata,
credential query params)
P5: System info disclosure (private
IPs, sensitive paths)
Annotates + optionally redacts.
Does NOT gate.
end note
alt output_warning flags detected
Session -> UI : SSE: output_warning\n{call_id, risk_level, flags,\nfunc_name, redacted}
note right
Credential values replaced
with [REDACTED:<type>] before
output enters conversation.
sanitized text excluded from
SSE payload (defense in depth).
end note
UI -> Storage : record_output_assessment()\nfire-and-forget persistence
note right
Stored: flags, risk_level,
annotations, output_length,
redacted (bool). Raw tool
output is never stored.
end note
alt human-gated items remain
UI -> UI : acquire publication lease; register ApprovalCycle\n(cycle_id, call_ids, event, result, witnesses)
UI -> Operator : approve_request with cycle_id + item verdicts
Operator -> UI : approve / deny by cycle_id or call_id
UI -> UI : atomically claim exactly one unresolved cycle
UI -> Operator : approval_resolved
UI --> Session : decision + optional feedback
UI -> Storage : stamp tracked verdicts with operator decision
else every item bypassed / auto-approved
UI -> Operator : tool_info with exact auto_approve_reason
UI --> Session : approved
end
== Lifecycle ==
note right of UI
Parallel task agents may register several ApprovalCycles. Each cycle owns
its own Event and result slot. A legacy selector-less decision targets the
oldest cycle; double resolution is a no-op. Cached LLM verdicts carry their
judge generation, so reused provider call ids cannot satisfy a new cycle.
end note
note over Session, Judge
**Lazy initialization:**
IntentJudge created on first approval if judge_config.enabled.
Re-uses session's provider/client by default (self-consistency).
Cross-model: separate provider/client from [judge] config.
== Cancellation boundary ==
**Sub-agent exemption:**
Task sub-agents skip intent validation entirely.
opt Stop / close / force-successor
Session -> Judge : abort all judge events owned by the cancelled operation
Session -> UI : resolve_all_approvals(False, "cancelled")
UI -> UI : block new admission leases; wait for admitted bundles;\nclaim only cycles whose cancellation witness is aborted
UI -> Operator : one cancelled resolution per claimed cycle
note over Session, UI
A Stop can win before cycle registration, during publication, or while a
click resolves. The witness + admission sweep makes exactly one terminal
outcome visible; a successor generation's new cycle is not swept.
end note
end
**Output guard:**
Runs when judge_config.output_guard is true (default).
Credential redaction when judge_config.redact_secrets is true.
note over Judge
Normal operator resolution does not necessarily cancel judge inference.
With cancel_on_approval=false, the daemon finishes and late verdicts remain
auditable. With it enabled, the batch event stops remaining judge work.
end note
**Storage:**
intent_verdicts table (migration 012), output_assessments table
(migration 022). Both queryable via admin API endpoints
(requires admin.judge permission). Skills store risk_level,
scan_report, scan_version for install-time risk assessment.
deactivate Judge
== Tool output guard ==
Session -> Session : execute admitted tools; truncate each result
Session -> Guard : evaluate(result, tool context, cancel event)
activate Guard
Guard -> Guard : heuristic checks first
opt LLM guard enabled and time remains
Guard -> Model : model_turn(output-guard lane, bounded prompt, cancel_ref)
Model --> Guard : structured verdict
end
Guard --> Session : assessment / redaction / warning
deactivate Guard
Session -> Session : re-check generation N before folding result
Session -> UI : output warning (no raw secret payload)
Session -> Storage : persist assessment + guarded Tool Turn metadata
note over Guard, Storage
Output-guard objects also pin model/config lanes. Replacement retires the
old object but lets admitted evaluations drain before its private client is
closed. A cancelled or superseded evaluation cannot fold into the successor
trajectory. Raw pre-redaction secrets are never stored in assessment rows.

to a human rather than executing the safe-looking subset piecemeal.
Every other outcome reaches a human: `review` / `deny` recommendations,

letting a confident LLM upgrade that default is the feature's purpose.
The Smart Approvals enabled flag, threshold, and bounded verdict wait are
captured as one immutable snapshot when each gate batch starts. A settings
reload takes effect on the next batch, while concurrent main-loop and
task-agent gates cannot mix fields from different reload generations. Stop
wakes a batch still waiting for verdicts and is linearized against the final
auto-approval commit: if Stop wins, no `smart_approval` decision or audit row
is recorded for tools that did not cross the gate.

## Why PgBouncer works well with turnstone
All turnstone database operations are short-burst queries: acquire a
connection, execute 1–3 statements, commit, release. No operation holds
a connection for more than a few milliseconds. This makes **transaction
pooling mode** ideal — PgBouncer assigns a real connection only for the
duration of each transaction, then returns it to the pool.
Most turnstone database operations are short-burst queries: acquire a
connection, execute a small transaction, commit, release. Workstream forks are
the deliberate exception: they clone the source's checkpoint-bounded history
and configuration and retain its attachment references in one transaction.
PostgreSQL runs that clone at `SERIALIZABLE` isolation and retries serialization
or deadlock conflicts as a whole. A large fork can therefore hold its assigned
server connection longer than an ordinary message write.
This still makes **transaction pooling mode** the right fit — no operation
depends on server-session state, and PgBouncer returns the connection as soon
as the transaction finishes. Size and monitor the server pool with concurrent
fork traffic in mind rather than assuming every transaction completes in a few
milliseconds.

## Upgrade note: deferred workstream creation
The workstream lifecycle now uses durable, hidden `state='creating'`
reservations while session construction, upload validation, and optional fork
cloning complete. Older server processes do not understand that private state:
against the same database they may resolve, list, open, or prune a reservation
before its new owner publishes it.
For the upgrade that introduces deferred creation, drain create traffic and
upgrade all server processes sharing the database as one cohort. Do not resume
creates until no older server process remains. The change needs no manual
schema migration, but it is not safe to treat mixed lifecycle implementations
as an ordinary rolling-upgrade state.
A `creating` row should be transient and absent from normal APIs and cluster
events. If one persists after a process crash, inspect the corresponding
`ws.create.*` and `session_mgr.commit_create.*` logs before cleanup. Do not
promote it to `idle` manually: its history, configuration, attachment
references, or lifecycle publication may be incomplete.

### Workstream lifecycle and project boundaries
The remote `/api/command` endpoint is conversation-local. It refuses
`/new`, `/workstreams`, `/resume`, and `/delete` because those local-CLI
helpers enumerate or mutate storage outside the HTTP resource gates. Remote
clients use the dedicated create, open, close, and delete endpoints instead;
`/rewind` and `/retry` have their own path-keyed, `conversation.modify`-gated
endpoints.
Passing `resume_ws` to create is an atomic **fork**, not an in-place resume.
It requires the ordinary create capability and source visibility. A private
project source is visible only to its workstream creator, project owner/member,
or authorized service-to-service cluster plumbing; denials use a not-found
response so guessed IDs do not become an existence oracle. The caller must also
be allowed to attach a new workstream to the source's current project. The
destination always inherits that effective project — a caller-supplied
`project_id` cannot re-file or declassify the conversation.
The canonical preflight atomically captures (and, for a legacy row, installs) a
private source-incarnation fence. The storage transaction compares that source
fence, rejects provisional sources, repeats the ACL/project check, and verifies
the persona/project construction snapshot, destination ownership and
incarnation, emptiness, and every referenced attachment before committing. A
source replacement, membership, project, persona, or destination-incarnation
race aborts the whole fork. Concurrent source-history writes serialize wholly
before or after the snapshot; no mixed or partially authorized history or
attachment reference becomes visible.

**Behavior after reload:**

workstream creation time, not read on every turn)

example, Smart Approval settings are snapshotted coherently at the start of
each approval batch.
- Settings marked `restart_required=True` need a server restart to take effect
### Model-definition reloads
The Models tab has a separate live-reload contract from ordinary ConfigStore
settings. Existing sessions remember the concrete registry generation that
supplied their active alias and re-resolve that alias at the start of the next
send. Endpoint, provider, backend model ID, capabilities, extra parameters, and
backend-auth configuration are replaced as one immutable binding. In-flight
turns, judges, and task agents finish or cancel against the binding they
started with; an admin edit never tears one request across two definitions.
Sampling and other saved workstream configuration remain workstream state. A
model-definition edit does not silently rewrite a live workstream's chosen
temperature, reasoning effort, max tokens, skill, or persona. Use
`/model <alias>` (or create/fork a workstream) when an explicit session-level
model switch is intended.
If a live workstream's alias is deleted, its next send first attempts the
configured fallback chain. Without a usable fallback, the operator-facing
error names the removed alias and points interactive users to `/model`; adding
the alias back causes the next send to rebind without a process restart. If a
replacement client cannot be constructed, Turnstone logs one
`session.model_refresh_client_construction_failed` warning per registry
generation and retries only after another model reload, avoiding a rebuild
storm on every send.

- `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.
- Ordinary placement is rendezvous (Highest Random Weight, HRW) selection over
the **full `ws_id`** and the current live server set. For each node, Turnstone
computes 32-bit FNV-1a over the node ID, a NUL separator, and the full
workstream ID; it then applies the node weight and selects the highest score.
A live per-workstream override takes precedence.
- The live set comes from recent `services` heartbeats. Placement can therefore
change when nodes join, leave, change weight, or an override changes. There
is no stable prefix-derived placement to pre-compute or persist.
- `workstreams.node_id` is stamped at creation and is not updated as HRW
placement changes. It supports display and liveness-safe cleanup; the console
router does not use it as the ordinary ownership decision.
- For multi-node imports, create through the console routing proxy when the
lifecycle must be published, or write the history once through the cluster's
configured **shared storage backend**. Never partition rows across node-local
databases by ID prefix or by a one-time HRW result: a later membership change
can route the same full ID to another node.
- For single-node imports, HRW placement is degenerate; any valid `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)
### 1. Quiesced storage import (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.
Use the current `turnstone.core.storage.StorageBackend` protocol against the
same shared backend as the cluster. The destination must remain absent from all
in-memory session managers while rows are changing: a loaded `ChatSession`
holds its own trajectory and will not observe conversation rows inserted behind
it.
The safe sequence is:
1. Normalize and validate the complete source transcript before writing.
2. Call `register_workstream(..., state="closed")` and require a `True` return;
`False` means the caller-selected ID already exists, so abort rather than
appending to an unrelated workstream.
3. Insert the ordered conversation rows and attachment references.
4. Load the saved rows back and run the validation checklist below.
5. Leave an archive closed. For a resumable import, only now invoke the normal
`POST /v1/api/workstreams/{ws_id}/open` endpoint on the currently routed
node so the session hydrates from the complete transcript.
Do **not** create the destination through the web/SDK create endpoint before a
direct bulk import. Create publishes an empty live session. If that already
happened, close the workstream and confirm the manager-authoritative live probe
returns false before writing, then explicitly open it again after validation.
For attachment-free history, `save_messages_bulk(rows)` is the canonical
single-transaction insert primitive and bypasses the LLM round-trip entirely.
New attachment bytes require the per-row path described under
[Attachments](#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`.
- **Blob identity**: `attachment_id` is the lowercase SHA-256 hex digest of the
bytes. `workstream_attachments` stores that content-addressed blob and its
refcount; it has no workstream or message foreign key.
- **Message link**: the sole message-to-blob link is the ordered JSON ID list in
`conversations.attachments`.
- **No persisted staging lifecycle**: pending upload bytes live only in a
node's in-memory attachment buffer. The old persisted
`pending → reserved → consumed` lifecycle does not apply to storage imports.
Two import paths:
For new attachment bytes, preserve row order by calling `save_message()` for
each turn. It returns the `conversations.id`; for every attachment referenced by
that turn, call `save_attachment()` with its content hash and bytes, then call
`set_message_attachments(ws_id, message_id, ordered_ids)`. Each
`save_attachment()` call accounts for one reference, while
`set_message_attachments()` records the ordered link.
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.
`save_messages_bulk(..., attachment_ids=[...])` is appropriate only when those
content-addressed blobs already exist: the bulk transaction retains their
references and writes the ordered lists. Do not first call `save_attachment()`
for a new reference and then pass the same reference to `save_messages_bulk()`;
both paths retain it and would double-count the refcount.
For full-history imports with multiple attachments at different turns, path (1) is the only option.
SDK multipart create remains useful only for attachments on a new first turn;
it publishes a live session and is not the full-history import path.

Before declaring success, verify:
- [ ] `ws_id` is 32-char lowercase hex.
- [ ] `workstreams` row exists with the right `user_id`, `state`, `kind`.
- [ ] The workstream remained closed and absent from every live manager while rows were written; archives stay closed and resumable imports are opened only after validation.
- [ ] `workstreams` row exists with the right `user_id` and `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.
- [ ] Every attachment ID is the SHA-256 of its stored bytes; each turn's ordered IDs are in `conversations.attachments`, and blob refcounts match message references.
- [ ] If multi-node: the row is in shared storage and the node selected by
`ConsoleRouter.route(ws_id)` from the current live set can load it.
`workstreams.node_id`, when present, is treated as a creation-time hint rather
than asserted equal to the current HRW result.
- [ ] Round-trip test: run `Storage.load_messages(ws_id)` and confirm the reconstructed list matches what you inserted (modulo timestamps).
## Anti-patterns
@@ -211,15 +286,20 @@ Before declaring success, verify:
- **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.

The ``stop_event`` parameter is shared by tests and production lifecycle

"""Tests for InteractiveAdapter.

Focus: the interactive lifecycle transport contract and ``cleanup_ui``
behavior (unblock pending events, broadcast ``ws_closed`` to per-UI
listeners, cancel + close session). The SessionManager-level tests

documented no-op stubs — ``ws_created`` is fired by the create HTTP
handler after attachment validation, and ``ws_state`` is fired by
``WebUI._broadcast_state`` with the full payload. No-op assertions
on those methods would be tautological given the class docstring,
so they're not retested here.
``emit_created`` now owns the bounded global-queue publication after the
HTTP handler has prepared and validated the create. ``emit_state`` and
``emit_rehydrated`` remain out-of-band/no-op on interactive.
