* fix(session): fail-closed history-commit handoff (#981)

The deleted-workstream discovery is now a terminal, ws_id-keyed latch:
keyed conversation commits refuse admission once the durable parent is
gone (convergence finalizers and force-abandon are exempt), history
handoff refuses to mint a proof token so /history fails closed with a
503 instead of silently wiping the pane, and the SSE stream carries a
workstream_gone resync reason. Discarded commits leave a forensic log
of commit keys and roles, never content.

Conversation rows gain a commit_key (migration 071): keyed saves are
idempotent under retry, validated against the full commit identity, and
refused when they would cross a workstream deletion. The prune orphan
category now requires a NULL alias plus a two-hour updated grace, with
cutoffs computed at discovery time and carried into both dialects'
rechecks.

The mid-turn interjection queue is owner-partitioned with no per-site
mode flags: pops take the acting principal's and unowned rows, other
participants' rows are structurally retained, and enforcement lives at
queue admission plus the shared before_spawn gates. The retraction
ledger is bounded by open pop windows: pops open a window atomically
with the queue delete, restores close their ids atomically with the
ledger consume, every other exit closes through one helper, and misses
for unheld ids record nothing. The workstream-gone latch refuses
unattended wakes at all three gates (watcher spawn, claim, delivery
pre-pop), and the retry dispatcher regained its pre-envelope
cancel/error convergence net.

Persistence-state reporting derives through the session bound to each
UI instead of a registry lookup by id that failed open to healthy
during tombstone retention. The dashboard roster no longer re-inserts
ghost entries from trailing activity events, the history tool-outcome
scan tolerates interleaved non-turn rows, and the shared
handoff-deadline handle owns its own retirement.

Single-sourced across call sites: keyed-commit row values, attachment
save wrappers, tail-truncation and conflict-resolution bodies for both
storage dialects; worker-slot lifecycle field sets; the direct-commit
admission frame; queued-row layout accessors; the string-aware comment
stripper shared by every JS harness suite.

* fix(session): sweep handoff fixes to their sibling surfaces

The interactive replay loop treated a system row as a tool-batch
boundary, so every tool result after an interleaved row vanished from
that pane while the coordinator rendered the same history correctly.
Only a conversational turn ends the batch window now, matching the
shared outcome index.

Accepted user turns clear the composer's attachment chips on the same
viewer policy that settles optimistic bubbles rather than on having
matched a local bubble, so a workstream created with an upload no
longer keeps a chip for an attachment the create dispatch already
consumed. The coordinator's raced-Stop arm emits the stream-end hook it
inherits alongside the idle state, leaving no unfinalized bubble or
unflushed tool output. Ending a session surfaces a failure toast when
the request never lands or answers with a non-JSON body.

The per-second persistence reconcile now probes each session without
blocking: a workstream whose generation and handoff locks are held is
skipped until the next pass instead of contending the locks every
commit needs. The one-shot repair that gates workstream creation at
capacity keeps a definite probe — it has no next pass, and the sessions
likeliest to be contended are the ones whose unresolved journals
emptied its candidate list.

Single-sourced: the attachment lane builds its conversation row through
the shared commit-identity builder; the ordinary worker exit releases
its slot through the lifecycle owner; both operator surfaces snapshot
their counters through one non-consuming helper; the replay preamble
loses its per-kind wrappers and its config hook; the browser harness
suites share one brace walker; and each in-flight history attempt is
one record carrying both its abort controller and its deadline.

Patrick Buckley edf52016ac refactor(core): lift list + saved verb bodies across both kinds (Stage 2 verb lift)
New ``make_list_handler(cfg)`` and ``make_saved_handler(cfg)``
factories in ``turnstone/core/session_routes.py`` replace four
pre-lift bodies (interactive ``list_workstreams`` +
``list_saved_workstreams``; coord ``coordinator_list`` +
``coordinator_saved``). Same factory + capability-flag pattern as
the merged cancel / open / events / create lifts.

Four new ``SessionEndpointConfig`` fields:

- ``list_resolve_titles: ListResolveTitles | None`` — bulk lookup
  ``(ws_ids) -> {ws_id: title-or-None}``. Interactive wires
  ``get_workstream_display_names`` (new bulk helper added on the
  storage layer + memory.py); the lifted body resolves every active
  row in ONE ``SELECT ... WHERE ws_id IN (...)`` instead of the
  pre-lift N+1 (one SELECT per row).
- ``list_kind: WorkstreamKind | None`` — explicit kind classifier
  for the saved-list storage filter. Replaces the initial draft's
  ``audit_action_prefix == "coordinator"`` string compare which
  would have silently leaked INTERACTIVE rows for any future kind
  whose audit prefix didn't match. Required when a kind mounts
  list/saved; misconfig surfaces as a 500 with a clear log line.
- ``saved_state_filter: str | None`` — coord wires ``"closed"``;
  interactive wires ``None``.
- ``saved_loaded_lookup: SavedLoadedLookup | None`` — coord-only
  defence-in-depth filter that excludes ws_ids in the warm pool.

Behaviour changes (all observable in CHANGELOG):

- **Active-list row shape converges on always-include** ``{ws_id,
  name, state, kind, parent_ws_id, user_id}``. Interactive renames
  ``id`` → ``ws_id``; both kinds populate every field (coord adds
  kind + parent_ws_id; interactive adds user_id).
- **Top-level response key converges on ``"workstreams"``** on
  both endpoints. Coord ``coordinators`` key removed — coord is a
  1.5.0aN-only surface (never shipped stable) so the convergence
  has no compat shim; SDK / frontend consumers swap once.
- **Storage + manager-lock work moved off the event loop on
  interactive**. ``list_workstreams_with_history`` runs through
  ``asyncio.to_thread`` on both kinds (matches coord's pre-existing
  perf-2 pattern from the saved-coordinators review); ``mgr.list_all``
  + per-row work also offloaded.
- **N+1 storage round-trips on /v1/api/workstreams eliminated**.
  Pre-lift interactive resolved the alias for every active row in a
  separate SELECT (up to 50 round-trips per dashboard refresh on a
  saturated node). Lifted body issues one bulk SELECT.

Pydantic schemas: ``WorkstreamInfo.id`` renamed → ``ws_id``,
``WorkstreamInfo.user_id`` field added. ``CoordinatorInfo`` and
``CoordinatorListResponse`` removed (folded into the unified
``WorkstreamInfo`` / ``ListWorkstreamsResponse``). OpenAPI spec
snapshots regenerated. TS SDK types updated (``WorkstreamInfo``
interface gains ws_id + the always-include fields); TS test
mock + assertion updated to match.

``GET /v1/api/dashboard`` is intentionally NOT in this PR's scope
and still returns rows keyed on ``id``. Tracked as a separate
cleanup PR (tombstone-note added at the dashboard handler).

/review pipeline run; the four Major findings + one Minor + six
nits all addressed in the same commit:

- M1: TS SDK ``WorkstreamInfo`` interface stale (id: string) →
  renamed + fields added.
- M2: TS SDK test masked the type-mismatch with stale mock → updated.
- M3: N+1 alias resolution on active list → bulk
  ``get_workstream_display_names`` helper + ``list_resolve_titles``
  bulk cfg hook.
- M4: Missing interactive parity regression test for unified row
  shape → mirror of coord's added in test_server_authz.py.
- Mi1: ``audit_action_prefix`` string-compare deriving kind →
  explicit ``cfg.list_kind: WorkstreamKind`` field.
- Six nits: redundant inner asyncio import, forward-ref quotes on
  Awaitable, duplicated frontend comments, dashboard ``id`` field
  has no tombstone-note, empty-coord_mgr short-circuit on
  ``saved_loaded_lookup``.

4512 tests passing; ruff + mypy clean.

Patrick Buckley a20a058c59 Add cluster-scale schema, fix console proxy UX, harden SDK sync runner (#22)
* Add cluster-scale schema, fix console proxy UX, harden SDK sync runner

Schema redesign for multi-node deployments:
- New `workstreams` table with node_id, state, lifecycle tracking
- Add node_id + ws_id columns to sessions table with indexes
- Full UUID (32 hex) for session_id and ws_id (was truncated 12/8)
- Server generates and owns node_id, bridge retrieves via /health
- Bridge retries with exponential backoff, fatal on auth errors
- WorkstreamManager persists workstreams and state changes to storage
- /health endpoint exposes node_id for bridge discovery

Console proxy UX fixes:
- Remove duplicate turnstone branding from proxy banner
- Same-tab navigation for Open Node UI and workstream deep links

SDK _SyncRunner fix:
- Sentinel pattern for StopAsyncIteration across thread boundary

Remove misplaced PNGs from docs/diagrams/ (correct copies in png/ subdir).

* Address PR #22 review feedback

- Fix CLI session_factory signature (ws_id param) — CI typecheck failure
- First-phase eviction in create() now calls _cleanup_ui + record_eviction
- close() persists "closed" state to storage via update_workstream_state
- Fix noqa comment in test to pragma: no cover

Patrick Buckley 5ee539c983 Add Python and TypeScript client SDKs for server and console APIs (#19)
* Add Python and TypeScript client SDKs for server and console APIs

Python SDK (turnstone/sdk/) with sync + async clients for both server
and console APIs. Returns Pydantic models directly, streams SSE events
as typed dataclasses. 27 event types with registry-based deserialization.
High-level send_and_wait() for request-response patterns.

TypeScript SDK (sdk/typescript/) with zero browser dependencies. Uses
fetch + ReadableStream for SSE parsing. Discriminated union event types
with type guards. Same API surface as Python SDK.

63 Python tests, 21 TypeScript tests (vitest). Comprehensive docs at
docs/sdk.md with SDK architecture diagram.

* Address PR #19 review feedback + fix lint
