Patrick Buckley 110d44b07e refactor(tools): remove man, math, and plan_agent built-in tools
`man` and `math` duplicated capabilities already reachable through
`bash`; `plan_agent` is better expressed as a `task_agent` running a
planning skill, and carried a large amount of special-case machinery
(plan-review gate, refinement loop, per-kind model routing). Removing
all three shrinks the tool surface and cuts per-call token cost.

Also removed, as dead-once-the-tools-are-gone:
- the `math` sandbox executor (`turnstone.core.sandbox`) and its
  `[sandbox]` extra; the eval analyst now runs bash-only
- the read-only `AGENT_TOOLS` sub-agent tool set and the `agent`
  tool-metadata key (`task_agent`/`TASK_AGENT_TOOLS` retained)
- the plan-review protocol end to end: the `on_plan_review` UI hook,
  `resolve_plan`, `POST /v1/api/plan` + `POST /v1/api/route/plan`,
  the `plan_review`/`plan_resolved` SSE events, and their Python SDK /
  TypeScript SDK / OpenAPI / frontend / Discord+Slack bindings
- the `model.plan_alias` / `model.plan_effort` settings and the
  registry `plan_model` / `plan_effort` routing fields

TOOLS 31->28, TASK_AGENT_TOOLS 13->11; COORDINATOR_TOOLS unchanged.

BREAKING CHANGE: removes the `man`, `math`, `plan_agent` tools, the
plan-review SSE/HTTP/SDK surface, and the plan_* model-routing settings
from the experimental 1.6 line.

Patrick Buckley 1728a4c0af feat(web-search): replace Tavily/DuckDuckGo backends with self-hosted SearxNG
Drop the Tavily and DuckDuckGo (ddgs) web_search backends for a single
self-hosted SearxNG service bundled into the docker-compose stacks.

Core:
- New SearXNGClient + _format_searxng; rewrite resolve_web_search_client to
  (backend, searxng_url, searxng_engines, ...). MCP backend + oauth_user guard
  unchanged. _resolve_search_client follows storage -> toml -> env -> default
  precedence (explicit "" disables, via ConfigStore.stored_keys()).
- Drop the Tavily-era topic=finance (no SearxNG category); topic is now
  general/news.

Settings/config:
- Remove tools.tavily_api_key, get_tavily_key, $TAVILY_API_KEY, [api].tavily_key.
- Add tools.searxng_url (default http://searxng:8080) + tools.searxng_engines,
  with get_searxng_url/get_searxng_engines.

Compose + bundled config:
- Internal-only searxng service (no published API port, :ro config, /healthz
  healthcheck, persistent searxng-cache volume) in both stacks; bundle
  turnstone/deploy/searxng/settings.yml (JSON output on, limiter off).
- Caddy serves the SearxNG web UI on :8444 (dev: localhost-only; prod: opt-in).
- bootstrap extractor + wheel packaging updated.

Deps: drop the ddg extra + ddgs mypy override (regenerates uv.lock, removing the
lxml/h2/brotli transitives).

Docs: tools/docker/architecture/openshell + diagrams + config example + CHANGELOG;
docs/docker.md carries the AGPL-3.0 §13 operator note.

BREAKING: tools.web_search_backend no longer accepts "tavily"/"ddg";
tools.tavily_api_key and the ddg extra are removed. Run the bundled SearxNG (ships
in the compose stacks) or set TURNSTONE_SEARXNG_URL to an external instance.

Closes #545

Patrick Buckley 20e1e7b110 fix(reasoning): apply Copilot review feedback + docs sync
PR #498 round-robin review surfaced 5 findings.  4 applied; 1 rejected
with rationale.

Applied

* **Copilot finding 5** (history_decoration.py:341): dispatcher
  inspected only ``provider_content[0]['type']``.  OpenAI Responses
  captures EVERY ``output_item.done`` event into ``provider_blocks``
  (not just reasoning) — in practice the order is
  ``[reasoning, message, ...]`` but the API doesn't guarantee that;
  a hypothetical ``[message, reasoning]`` ordering would silently
  drop the reasoning under an index-only check.  Now walks the list
  for the first block whose type is in ``_BLOCK_TYPE_PROVIDER_FACTORY``,
  then dispatches the WHOLE list to that provider's extractor.  Each
  provider's extractor already filters internally by its own block
  type, so passing the full list is correct.  Regression test added
  (``test_dispatcher_scans_past_unrecognized_first_blocks``).

* **Copilot finding 3** (migration 052 docstring): the previous
  review-fix wave used sed to rename ``persist_reasoning`` →
  ``surface_persisted_reasoning`` everywhere, which mangled a
  historical reference in the migration docstring ("The earlier name
  ``surface_persisted_reasoning`` was renamed...").  Restored to
  point at the actual pre-rename name (``persist_reasoning``).

* **Copilot finding 4** (sdk/typescript/src/events.ts:26):
  ``HistoryEvent`` JSDoc still referenced ``persist_reasoning`` —
  the sed rename only walked ``turnstone/`` and ``tests/``, missing
  the TypeScript SDK.  Updated to ``surface_persisted_reasoning``.
  Also widened the comment to cover all three reasoning-bearing
  block types (Anthropic ``thinking``, OpenAI Responses ``reasoning``,
  synthetic ``reasoning_text``) instead of mentioning only Anthropic.

* **github-code-quality finding** (session.py:1120): ``_resolve_server_type``
  had a bare ``except Exception: pass``.  Replaced with a
  ``log.debug(..., exc_info=True)`` + explanatory comment.  Behaviour
  unchanged (still returns ``""`` on any lookup failure); failures
  are now observable under DEBUG triage.

Rejected (with rationale)

* **github-code-quality finding** (_protocol.py:265):
  ``extract_reasoning_text``'s body is ``...`` per ``LLMProvider``
  Protocol convention.  Every method in the file uses ``...`` (PEP
  544 idiomatic Protocol style).  Changing only this one to
  ``raise NotImplementedError`` would be inconsistent with the rest
  of the file.  CodeQL's "statement has no effect" warning is
  technically correct for ``...`` as a standalone expression but
  ignores the documented Python Protocol convention.  No fix.

Docs sync

* docs/api-reference.md: ``history`` SSE event message-shape table
  gains the optional ``reasoning`` field.
* docs/architecture.md: ``ModelCapabilities`` row in the type table
  gains ``supports_reasoning_replay``; ``StreamChunk`` and
  ``CompletionResult`` rows gain the existing ``provider_blocks``
  field (was missing pre-PR).  New "Per-model reasoning persistence"
  subsection under the Models config section, documenting the two
  flags + capability gate + three reasoning paths + cross-provider
  shape filter.
* docs/settings.md: new "Reasoning persistence (per-model)"
  subsection with the two-flag table and capability-gate note.
* docs/diagrams/03-core-engine-classes.puml: ``LLMProvider`` interface
  adds ``extract_reasoning_text`` + the new ``replay_reasoning_to_model``
  kwarg; ``ModelCapabilities`` class adds ``supports_reasoning_replay``.
  PNG regenerated.

Lint + test gate

* ruff check + ruff format clean.
* mypy clean (191 source files).
* pytest -m 'not live' — 6116 passed (3 deselected), +1 net new test
  (``test_dispatcher_scans_past_unrecognized_first_blocks``).

Patrick Buckley 57cb09c871 docs(sse): document state_change + in_progress_snapshot events
Updates the docs that describe the per-workstream SSE event stream and
the SessionUI lifecycle to match the refresh-resume changes:

- api-reference.md: documented the `state_change` event (previously
  undocumented despite already being a live event) and the new
  `in_progress_snapshot` event; rewrote the multi-consumer fan-out
  paragraph to mention the kind-specific replay tail (state_change +
  optional in_progress_snapshot) so the "no catch-up needed" claim
  is no longer misleading.
- architecture.md: bumped the SessionUI Protocol stub to 16 methods
  (added `on_turn_start` / `on_turn_committed`) and pointed at the
  in_progress_snapshot section in the API reference.
- sdk.md: added rows for `state_change`, `in_progress_snapshot`, and
  `approval_resolved` (preexisting gap) to the per-workstream event
  table.
- coordinator-api-tour.md: added an `in_progress_snapshot` row to the
  event table and rewrote the reconnection-contract paragraph to
  cover mid-stream content/reasoning restoration.
- diagrams/04-conversation-turn.puml: added `on_turn_start()` before
  the thinking-start emit and `on_turn_committed()` immediately after
  `messages.append(assistant_msg)`, with notes explaining the inflight-
  buffer reset semantics. PNG regenerated.

Patrick Buckley eb2a119da9 refactor(mcp): remove periodic refresh, add manual refresh/reconnect controls
Deletes the _periodic_refresh task and its supporting state
(_refresh_task, _refresh_failures, _refresh_backoff_until,
_REFRESH_BACKOFF_BASE/MAX, _DEFAULT_REFRESH_INTERVAL, refresh_interval
kwarg) from MCPClientManager. Push notifications and operator-driven
manual refresh now cover all catalog-update needs; the long-running
4-hour timer was dead complexity that obscured the per-user pool
work to come.

Catalog freshness on auto-reconnect is preserved by scheduling an
unblocking _refresh_server task on the mcp-loop after _connect_one
succeeds; the calling thread returns immediately so half-open
recovery latency does not double. Adds MCPClientManager.reconnect_sync
(clears the circuit, closes any existing session, calls _connect_one,
clears stale catalog on failure).

Wires a new pair of operator endpoints —
POST /v1/api/admin/mcp-servers/{name}/refresh and
/v1/api/admin/mcp-servers/{name}/reconnect — that fan out to all
nodes through the existing _internal route family, with per-row
"Refresh" and "Reconnect" buttons in the MCP Servers admin tab.
The new node-internal paths /api/_internal/mcp-{refresh,reconnect}/
are gated to the approve scope to prevent direct unprivileged
reconnects bypassing the console's admin.mcp gate. Internal
endpoints return generic error messages and a filtered status
payload (no command/url) to keep transport details admin-gated.

Drops the [mcp] refresh_interval setting, the
--mcp-refresh-interval CLI flag, and the matching config-mapping
entry; updates docs/architecture.md, docs/tools.md,
docs/settings.md, and the three PlantUML diagrams that referenced
the periodic loop.

Tradeoffs (intentional):
- Idle nodes will not auto-rejoin a recovered MCP server until
  traffic arrives or an operator clicks Reconnect. The previous
  background reconnection loop is gone by design — push
  notifications + operator controls replace it.
- Console fan-out blocks on the slowest node (existing pattern);
  not changed here.

This is Phase 1 of the OAuth-MCP series — feature subtraction
ahead of per-user state.

Patrick Buckley d6e615d324 fix: apply /review feedback on legacy URL cleanup
Reviewer caught real misses on the consumer-swap claim:

- TypeScript SDK still defined and re-exported `CloseWorkstreamRequest`
  (types.ts + index.ts) — drop both. Now matches the Python-side
  removal.
- Four `tests/test_auth.py` cases (`test_write_full_token_ok`,
  `test_approve_full_token_ok`, `test_bearer_takes_precedence_over_cookie`,
  `test_cookie_full_on_write_ok`) were tautological after the legacy
  URL removal: they posted to `/api/send` / `/api/approve` and asserted
  `allowed is True`, but those paths now classify as `read` so a read
  token would also pass — they no longer tested the write/approve
  scope enforcement. Swap to path-keyed URLs to restore the original
  intent.
- `is_public_path("/api/send")` test renamed + retargeted to a
  path-keyed URL.

Doc-table drift the previous commit missed:

- `docs/security.md` path-to-scope mapping rewritten for the
  path-keyed verb family (write set, DELETE-on-/send dequeue,
  per-ws_id approve).
- `docs/architecture.md` scope-model row text swap from `/api/send`
  / `/api/approve` to the path-keyed equivalents.
- `docs/diagrams/01-system-context.puml` channel→server edge label
  swap.
- `docs/diagrams/15-auth-architecture.puml` scope class swap.

Cosmetic comment-only stragglers:

- `tests/test_session_worker.py` module docstring URL update.
- `tests/test_ratelimit.py` ~11 `/api/send` fixture-key strings
  retargeted to `/api/workstreams/abc/send` so the URL fixtures
  reflect the post-1.5 surface (rate limiter is path-agnostic; the
  swap is purely cosmetic).

4557 tests still passing under -m "not live"; ruff + mypy clean.

Patrick Buckley ad0e7ce6eb docs: mark 1.5.0 legacy URL surface removal
CHANGELOG [Unreleased] / Removed (BREAKING — 1.5.0) block calling out
the legacy URL family removal with the swap table. Doc passes on
api-reference.md (per-endpoint sections rewritten with path
parameters and slimmer body shapes), architecture.md (handler-list
diagram and console-proxy URL example), console.md (URL-rewriting
JS shim docstring + SSE proxy example), and the two PlantUML
diagrams (11-console-data-flow, 16-channel-architecture).

Also picks up two test-side stragglers from step 5 that referenced
the legacy adapters in a docstring + a stale /v1/api/events SSE
test: turn into path-keyed equivalents. OpenAPI JSON dump regenerated
to reflect the catalog edits from step 3.

After this commit:
- 4557 tests passing under -m "not live"
- ruff + mypy clean on turnstone/ tests/ sdk/
- grep for "/v1/api/send", "/v1/api/approve", "/v1/api/cancel",
  "/v1/api/workstreams/close" returns zero hits across turnstone/
  sdk/ docs/ tests/ (excluding CHANGELOG.md, which intentionally
  documents the old shape).
- grep for make_legacy_body_keyed_adapter, make_legacy_query_keyed_adapter,
  _make_method_dispatch, close_legacy returns zero hits.

Patrick Buckley a76d93b6c6 docs(coordinator): phase 8 PR C — API tour, skills guide, bulk-endpoints contract + wait diagram (#388)
* docs(coordinator): phase 8 PR C — API tour, skills guide, bulk-endpoints contract

Four deliverables that close out the phase 8 doc debt carried since
phase 1:

- docs/coordinator-api-tour.md — 9-step lifecycle walkthrough
  (create → subscribe → send → inspect children / detail → wait for
  fan-out → govern (trust / restrict / stop_cascade / close_all_children)
  → approve / cancel → close), one request + response per step, every
  SSE event type the UI has to handle, and every operation id cross-
  referenced against the live /openapi.json.  Integrators driving a
  coord session from a custom UI or SDK can work end-to-end from this
  doc without reverse-engineering the console page.

- docs/coordinator-skills.md — writing a SkillKind=COORDINATOR skill.
  Tool-surface diff (13 orchestration tools, no bash / edit / web /
  sub-agent), persona diff (orchestrator vs maker, composing on
  base_coordinator.md), SkillKind enum + migration 044, task_list
  integration, ws_id handling, wait vs inspect cost profile, three
  orchestration patterns (delegate-and-summarise, fan-out-and-
  synthesise, plan-then-delegate), testing surface.

- docs/bulk-endpoints.md — codifies the two shape idioms that shipped
  across phases 6–8: {results, denied, truncated} for bulk-read /
  bulk-create-with-payload (cluster/ws/live, spawn_batch); {<bucket>,
  failed, skipped} for cascade-mutation (stop_cascade,
  close_all_children).  Picks-by-semantics guidance so the next bulk
  endpoint author doesn't coin a third shape.

- docs/diagrams/27-coordinator-wait-for-workstream.puml + rendered
  PNG — sequence diagram covering spawn → wait (blocking, with
  bounded progress emission) → inspect → close.  Embedded in the
  API tour doc's §6 so the "why is my coord session blocking?"
  question has a visible answer.

No code changes.  All operation ids in the API tour verified against
a live build of the console spec; all markdown internal links
resolve; PlantUML renders clean on the system plantuml jar.

* docs(coordinator): address PR #388 copilot review

- api-tour.md child-event payload keys: events stamp `ws_id` as the
  coord's own id and carry the child's id separately as
  `child_ws_id`.  Doc previously listed `ws_id` as the child
  identifier on all four child_ws_* events, which would send SDK /
  UI implementers parsing the wrong field.
- api-tour.md SSE table: add the `status` event emitted by
  ConsoleCoordinatorUI.on_status (token usage + context_window +
  effort snapshot; fires on every streaming tick).  Previously
  omitted from the "every event type a UI has to handle" list.
- api-tour.md /children response key: server returns `{items,
  truncated}`, not `{children, truncated}`.  Also drop the
  `state=closed` query-param claim — the endpoint has no state
  filter; clients filter locally on the returned `state` field.
- skills.md task_list shape: the persisted row uses `id` (not
  `task_id` — the input schema uses `task_id`, the row uses `id`),
  has `child_ws_id` / `created` / `updated` (no `notes` field),
  and supports a 5th `reorder` action alongside add/update/remove/
  list.  Adds the parallel-dispatch caveat from the tool
  description.
- skills.md tenant-guard behaviour: foreign / hallucinated ws_ids
  don't return an empty result — they return explicit
  error/not-found/denied shapes that differ by op (mutating ops
  return `{error, status: 404}`; inspect returns `{error}`; wait
  reports state=denied).  Important distinction — a skill that
  expects empty on mismatch will mishandle every single case.

Docs-only; no code / schema / SDK changes.  All internal links
still resolve.

Patrick Buckley 9826ea15c5 feat(coordinator): phase 7 — governance + skill metadata + cross-cutt… (#383)
* feat(coordinator): phase 7 — governance + skill metadata + cross-cutting invariants

Combines three stacked sub-PRs into a single coordinator phase-7
shipment against the phase-7 plan doc.  The sub-PR structure (0 / A /
B) preserved on individual branches for reviewer drill-down; this
branch is the one reviewers should merge.

## Sub-PR 0 — service-auth boundary invariants

Shared helpers and contracts that lock the console ↔ node service-auth
boundary so later authz surfaces use them by construction.

- ``_effective_user_filter(request)`` in both ``turnstone.console.server``
  and ``turnstone.server`` with a shared ``DENY_EMPTY_SUB`` sentinel
  on ``turnstone.core.auth``.  Three-way return — admin/service
  bypass, scoped caller uid, or fail-closed sentinel on blank sub.
  Four callsite migrations (``_coordinator_rows``,
  ``coordinator_children``, ``coordinator_metrics``,
  ``cluster_ws_live_bulk``).

- ``StorageBackend`` class docstring codifies the tenancy contract
  (every list/count/aggregate method must accept ``user_id: str |
  None = None`` and push ``WHERE user_id = :user_id`` into SQL) and
  the ``_mapping`` row-access contract.  New
  ``turnstone.testing.row_contract`` ships ``assert_row_like()``.

- ``_verify_collector_service_scope`` probes an upstream node at boot
  with ``expected_node_id=_scope-probe_``; a 409 proves the scope
  gate was passed, a 403/401 sets ``collector_scope_error`` and
  causes ``cluster_snapshot`` / ``cluster_events_sse`` to return 503
  with a remediation hint.  Probe URL allowlist rejects non-http(s)
  schemes and 169.254.0.0/16 hosts.

- 4xx log-level floor on ``_NodeDashboardCache.get``,
  ``_fetch_live_block``, and ``_proxy_sse`` — dotted-hierarchy
  prefixes with bounded body previews.  ``_bounded_body_preview`` and
  ``_bounded_stream_preview`` strip control chars.

## Sub-PR A — coordinator governance core

Mid-session governance surface for coordinator workstreams.

- **Trusted-session mode.**  New ``coordinator.trust.send``
  permission (migration 042).  ``ChatSession.set_trust_send`` /
  ``revoke_tools`` methods with a ``_governance_lock``.  ``POST
  /v1/api/coordinator/{ws_id}/trust {send: bool}`` double-gated on
  ``admin.coordinator`` AND ``coordinator.trust.send`` with
  ``allow_service_bypass=False`` so service tokens can't escalate.
  ``_prepare_send_to_workstream`` auto-approves sends whose target is
  in the coordinator's own subtree; foreign ws_ids still require
  approval.  ``_is_own_subtree`` checks both ``parent_ws_id`` AND
  ``user_id`` to defend against cross-tenant row corruption.

- **Audit-layer credential redaction.**  ``record_audit`` walks
  ``detail`` (dicts, lists, tuples, sets, frozensets; keys too)
  and routes every string through ``redact_credentials`` + a C0
  control-char scrub.  New kw-only ``raw_detail=True`` opt-out.
  ``_has_any_string`` fast-path.  Audit action registry extended
  with the four new governance sub-prefixes.

- **Mid-session revocation + cascading stop.**  ``POST
  /v1/api/coordinator/{ws_id}/restrict {revoke: [...]}`` caps 256
  entries / 128 chars; ``_prepare_tool`` short-circuits with a
  tool-error.  ``POST /v1/api/coordinator/{ws_id}/stop_cascade``
  cancels the coord's in-flight generation then dispatches
  ``cancel_workstream`` for every direct child in parallel via
  ``asyncio.gather`` bounded by ``Semaphore(16)``.  Per-child
  outcomes split into ``cancelled`` / ``failed`` / ``skipped``
  (404 = already-gone rather than dispatch-broken).  Both endpoints
  apply ``allow_service_bypass=False`` on the admin gate.

- **Shared plumbing.**  ``_resolve_coord_session`` helper collapses
  the handler prelude three endpoints shared.  ``_emit_coord_audit``
  wraps ``record_audit`` in a dedicated ``ThreadPoolExecutor``
  (``app.state.audit_executor``) so audit bursts don't starve cancel
  dispatches.  ``_require_json_object`` guards body parsing so non-
  object JSON returns 400 instead of 500.

## Sub-PR B — skill metadata governance

- **Description validator (migration 043).**  ``prompt_templates``
  rows now require a non-empty ``description``.  Existing empty rows
  get backfilled with a ``"Skill: <name>"`` placeholder on upgrade.
  The installer (``admin_skill_discover``) and MCP prompt sync both
  synthesise a placeholder when the upstream description is blank
  so non-admin write paths satisfy the invariant.

- **Skill kind classifier (migration 044).**  New
  ``prompt_templates.kind`` column (``interactive`` / ``coordinator``
  / ``any``; defaults to ``any``).  New
  ``turnstone.core.skill_kind.SkillKind`` StrEnum is the single
  source of truth; Pydantic schemas type ``kind`` as ``SkillKind``
  (OpenAPI advertises the enum) and the handler validator catches
  the ValueError.  ``list_skills_filtered`` gains a
  ``kinds: list[str] | None = None`` SQL filter.
  ``CoordinatorClient.list_skills`` defaults to
  ``kinds=["coordinator", "any"]`` so interactive-only skills are
  hidden from the orchestrator.

- **``scan_status`` → ``risk_level`` rename (migration 045).**
  Lossless column rename to align with ``IntentVerdict.risk_level``
  terminology.  Swept storage (both backends + schema + protocol),
  handlers, API schemas, tool JSON, generated OpenAPI specs,
  TypeScript SDK types, frontend (``governance.js``), tests, and
  English prose in ``docs/judge.md`` + ``docs/tools.md``.  The
  user-facing on-load warning now reads ``has risk level:
  {risk_tier}``.  Tool JSON's ``risk_level`` enum corrected to the
  scanner's actual taxonomy (``safe / low / medium / high /
  critical``; was the never-shipped ``clean / flagged / unscanned /
  pending``).  Historical migration 021 left untouched.

## Migrations

042 (``coordinator.trust.send`` perm — PR A)
043 (description backfill — PR B)
044 (``kind`` column add — PR B)
045 (``scan_status`` → ``risk_level`` rename — PR B)

All four use position-anchored permission strings / host-side
parse-filter-rejoin on downgrade where SQL ``REPLACE`` could
corrupt prefix-overlapping values.

## Verification

- ``ruff check turnstone tests`` clean.
- ``mypy turnstone`` clean on 165 source files.
- ``pytest -m "not live"``: 4431 passed (+85 over the phase-6
  baseline).  Includes +32 tests in ``tests/test_service_auth_boundary.py``
  and +38 in ``tests/test_coordinator_governance.py``; shared fixtures
  extracted to ``tests/_coord_test_helpers.py``.
- Generated OpenAPI JSON (``sdk/typescript/openapi-{console,server}.json``)
  regenerated via ``sdk/typescript/scripts/generate-types.py``; zero
  ``scan_status`` occurrences remaining outside the historical
  migration 021 and the rename migration 045.

## Security reviews

Both reviews flagged by the phase-7 plan (items 1 + 5, plus 0a's
refuse-to-serve gate) ran through the multi-stage ``/review``
pipeline twice per sub-PR; all confirmed findings landed in-branch.

* fixup(phase-7): CI lint + PR #383 review fixups

Addresses the lint CI failure (ruff format) plus 12 findings from the
two automated PR reviewers.

Copilot:
- ``_sqlite.list_installed_skill_urls`` / ``_postgresql.list_installed_skill_urls``
  used positional row indexing (``r[0]``/``r[1]``/``r[2]``) while this
  same PR's ``StorageBackend`` class docstring forbids it.  Switched
  both to ``r._mapping["..."]`` access.
- ``list_skills.json`` previously advertised ``risk_level=""`` as a
  filter for unscanned skills, but the implementation treats empty
  strings as "no filter".  Clarified the tool description to say
  omit the filter entirely to include unscanned rows, and added an
  explicit ``enum`` on the parameter restricting it to the scanner
  tiers.  ``_prepare_list_skills`` keeps the ``strip() or None``
  normalisation — unscanned filtering now has an unambiguous contract.
- ``test_storage_skills_filtered.test_risk_level_filter`` used the
  legacy ``clean`` / ``flagged`` values from the pre-rename column.
  Rewritten with the scanner's actual taxonomy (``safe`` / ``high``).

github-code-quality (CodeQL):
- ``test_deny_sentinel_is_singleton`` previously asserted
  ``cs.DENY_EMPTY_SUB is cs.DENY_EMPTY_SUB`` — an identical-expression
  comparison.  Rewritten as two separate ``from ... import ... as`` aliases
  (``FIRST_READ`` / ``SECOND_READ``) so the identity check is between
  distinct bindings.
- ``test_restrict_empty_revoke_is_noop_but_audits`` unpacked ``state``
  without using it.  Renamed to ``_state``.
- Mixed import styles in ``test_service_auth_boundary.py`` — the
  file previously used both ``import turnstone.console.server as cs``
  and ``from turnstone.console.server import ...`` for the same
  module (same story for ``turnstone.core.auth`` and
  ``turnstone.server``).  Consolidated to the ``from X import Y`` style
  used elsewhere in the file; the ``_fetch_live_block`` test now
  patches via pytest's ``monkeypatch`` fixture instead of a manual
  rebind through a module alias.

CI:
- ``ruff format`` reformatted one line in
  ``tests/test_coordinator_endpoints.py``.

Verification: ruff check + mypy clean (166 files); 4459 non-live
pytest pass.

* fix(tests): swap asyncio marker for anyio in service-auth boundary tests

PR #383 CI caught that the 13 ``@pytest.mark.asyncio`` decorators I
added in ``test_service_auth_boundary.py`` are an off-convention
choice — the rest of the repo uses ``@pytest.mark.anyio`` (148 sites
vs my 13).  The CI environment pulls in ``anyio`` but not
``pytest-asyncio``, so every async test in this one file was failing
with "async def functions are not natively supported".  It passed
locally by accident — my dev venv happens to have pytest-asyncio
installed ambiently.

Swapped all 13 marker sites to ``@pytest.mark.anyio``.  No functional
change; the tests run under the same default asyncio backend anyio
provides.

Verification: ruff + mypy clean (166 files); 4459 non-live pytest
pass.

Patrick Buckley 37ed6bbf5b feat(core): WorkstreamKind enum + list_workstreams user_id filter (#374)
Foundation PR for the multi-stage-review follow-up.  Introduces a
single source of truth for workstream kind values and pushes tenant
scoping into the storage protocol so list callers can't forget to
filter client-side.

- WorkstreamKind(StrEnum) replaces bare "interactive" / "coordinator"
  literals across 17 production modules.  Strict mypy narrows every
  internal call site; raw strings still work at wide boundaries
  (HTTP body, DB row) via WorkstreamKind(raw) parse at the edge.
- StorageBackend.list_workstreams(..., user_id=None) adds a SQL-level
  WHERE user_id = :user_id gate on both sqlite and postgres impls.
  Memory wrapper forwards the new filters.
- register_workstream now validates kind at the storage edge so SDK /
  restore / internal callers can't silently corrupt the NOT NULL
  column with empty / mis-cased / unknown values.
- WebUI.__init__ normalizes empty-string parent_ws_id to None, matching
  the storage-edge and WorkstreamManager invariants.
- POST /v1/api/workstreams/new parses body["kind"] through the enum
  and returns 400 on unknown kinds instead of silent coercion.

Absorbs bug-1, bug-2, bug-4/q-6, q-1, q-8, and partial q-2 (wrapper
signature forwards the new filters; full deletion of the unused
wrapper stays in the cleanup PR).

Patrick Buckley 471d1a3311 docs: audit documentation for 1.4 / 1.5 state
Systematic pass over every doc under docs/, the root-level README /
QUICKSTART / CONTRIBUTING, and the PlantUML diagrams.  Memory and docs
had drifted against the code since 1.2 — this catches them up to the
1.4.0 release and the 1.5.0a1 experimental line.

User-facing fixes
- README: fix broken docs/mcp.md link (→ mcp-registry.md); channel
  gateway entry reflects shipped Discord + Slack adapters instead of
  "Slack/Teams planned"; diagrams table mentions both.
- QUICKSTART: docs/*.md relative links were wrong from the repo root;
  wizard version bumped from 0.5.4.
- CONTRIBUTING: add dev extra plus the ruff / mypy / pytest commands
  we actually expect before push.

Reference docs
- architecture.md: 19 tool schemas (was 15), 18 admin tabs (was 14),
  turnstone-bootstrap added to entry-points table, OpenAI provider
  file split (chat/responses/common) documented, 38 SDK event
  dataclasses (was 27 and referenced deleted mq/protocol.py), Slack
  adapter + multi-adapter gateway, plan_agent/task_agent naming,
  governance admin-panel rewrite.
- api-reference.md: full attachment endpoints (POST/GET/content/
  DELETE on /v1/api/workstreams/{ws_id}/attachments) plus the
  multipart mode on POST /v1/api/workstreams/new.
- channels.md: Slack Setup section (Socket Mode app creation, OAuth
  scopes, tokens), Slack CLI/env reference in config table, combined-
  adapter architecture diagram.
- console.md: 18-tab listing (was 13) with Channels/Models/Nodes/TLS
  descriptions and ConfigStore live-edit note.
- docker.md: Slack env vars block; image entry-point list now
  includes turnstone / turnstone-bootstrap.
- sdk.md: attachments methods on the server client, attachments
  example (upload-then-send and at-creation), event count fixed.
- releasing.md: four-track table (stable/1.0, 1.3, 1.4 + main 1.5);
  promotion workflow uses 1.5 / 1.6 numbering.
- settings.md: plan_model / task_model / plan_effort / task_effort
  overrides section.
- governance.md: skill naming (/skill, `skill` field — not /template),
  Prompts/Judge tabs called out.
- security.md: two-token-types wording; src claim values match the
  AuthResult source strings actually emitted.
- mcp-registry.md: SDK package name is @turnstone/sdk.
- tools.md: plan / task renamed to plan_agent / task_agent in the
  section headings and summary table; primary-key table matched.
- design/consistent-hash-ring.md: dead direct-http-transport.md
  pointer redirected to architecture.md.

Diagrams
- 02-package-structure: drop phantom chat.py entry point, add admin
  and bootstrap, add slack/bot.py, rename channels/gateway.py →
  channels/cli.py.
- 16-channel-architecture: Slack is no longer "(future)", add a
  SlackBot class and the slack-bolt Socket Mode edges; wire the new
  bot into ChannelService.  PNGs regenerated from both puml sources.

Patrick Buckley 934cb075d6 feat: per-model sampling parameters (temperature, max_tokens, reasoni… (#350)
* feat: per-model sampling parameters (temperature, max_tokens, reasoning_effort)

Model sampling parameters were global-only settings applied uniformly to
all models. Different models have fundamentally different requirements
(o-series needs no temperature, Anthropic needs temp=1.0 with thinking,
local models may need different max_tokens). This adds per-model overrides
with global fallback so each model definition can specify its own defaults.

Migration 036 adds nullable temperature, max_tokens, reasoning_effort
columns to model_definitions. NULL inherits the global default from
ConfigStore. The session factory and /model switch command both resolve
per-model override → global fallback consistently.

The admin UI model create/edit modal now has dedicated form fields for
these parameters with client-side validation, a visual section divider,
and per-model override hints in the model table rows.

Removes vestigial model.name and model.context_window global settings
(now handled per-model by the model registry) with startup warnings for
existing config.toml users.

* fix: defensive parsing for config.toml per-model sampling params

Wrap temperature/max_tokens conversions in try/except with range
validation. Invalid values log a warning and fall back to None
(inherit global default) instead of aborting registry load.

Patrick Buckley 2bfc0f2c5d fix: harden MCP client against misbehaving servers (#296)
* fix: harden MCP client against misbehaving servers

Misbehaving/failed/misconfigured MCP servers could peg CPU at 100% due
to anyio cancel-scope busy-loops (SDK #2147), uncancelled orphaned
futures, and missing application-layer resilience.

Five fixes:

1. Cancel orphaned futures on timeout — future.cancel() in all sync
   bridge methods prevents coroutine accumulation on the event loop

2. Per-server circuit breaker — 3-failure threshold with exponential
   cooldown (30s–5min), per-server jitter, auto-reconnect on half-open
   probe, McpError excluded (protocol errors from healthy servers)

3. Safe transport stream pre-close — store stream refs and close them
   before stack teardown in all error/shutdown paths, preventing the
   anyio zero-buffer CPU busy-loop

4. Notification debounce — 5s per-server rate limit on list_changed
   refresh storms from buggy servers

5. Periodic refresh backoff with auto-reconnect — disconnected servers
   get reconnection attempts with exponential backoff (60s–1hr) instead
   of being silently skipped forever

* docs: add MCP resilience section to architecture docs and diagram

Document the circuit breaker, future cancellation, stream pre-close,
notification debounce, and periodic refresh backoff in the architecture
guide and the MCP architecture PlantUML diagram.

* fix: address review — stack leak on transport error, half-open comment

- Widen _connect_one guard to check _per_server_stacks too, not just
  _sessions. Transport errors in sync dispatch methods evict the session
  but left the stack behind, leaking anyio tasks on reconnect.
- Clarify half-open design: multiple callers are intentionally allowed
  through (reconnects serialize on the event loop, first failure re-trips).

Patrick Buckley 9a518657a3 feat: replace console HTTP polling with persistent SSE streams (#266)
* feat: replace console HTTP polling with persistent SSE streams

Console collector now subscribes to each server node's /v1/api/events/global
SSE stream for real-time state updates instead of polling /v1/api/dashboard
and /health every 15 seconds.

Server changes:
- Emit ws_created/ws_closed events on global queue from create/close handlers
- Add node_snapshot on SSE connect (workstreams, health, aggregate)
- Add ?expected_node_id= identity verification (409 on mismatch)
- Add health_changed callback to BackendHealthMonitor circuit breaker
- Add periodic aggregate emitter thread (10s)

Console collector changes:
- Single asyncio event loop on one thread multiplexes all SSE connections
  (scales to 1000+ nodes vs thread-per-node)
- Discovery loop spawns/cancels async SSE tasks per node
- Snapshot reconciliation on connect, delta application for live events
- Fix ws_state→cluster_state event type mismatch
- Remove polling code (poll_interval, max_poll_workers, --poll-interval CLI)

SDK changes:
- Add NodeSnapshotEvent, HealthChangedEvent, AggregateEvent dataclasses
- Add stream_node_events() method (async + sync)

* fix: address review feedback on node event streams

- Fix stop() to let SSE manager exit naturally instead of force-stopping
  the event loop (ensures finally cleanup runs)
- Guard against empty/invalid SSE data from ping frames
- Treat missing node_id as identity mismatch (409) when expected_node_id
  is provided
- Fix stale docstring on _update_metrics

Patrick Buckley a315cabe71 chore: polish — remove dead code, update diagrams and docs
Remove stale Redis/Bridge/MQ references found via vulture scan and
manual grep:

Update 7 diagrams to reflect direct HTTP architecture:

Patrick Buckley 405baf7cb2 fix: memory list/search cross-workstream scope leak (#253)
* fix: scope-filter memory list/search to current workstream and user

Unscoped memory(action='list') and memory(action='search') returned all
memories across all workstreams. Now applies the same 3-query pattern
(global + current workstream + current user) used by system prompt
injection.

* fix: validate user scope on memory search/list for unauthenticated sessions

Adds _validate_scope guard to search and list prepare paths, matching
save/get/delete. Prevents explicit scope='user' from returning all
user-scoped memories when session is unauthenticated.

* fix: update _get_visible_memories references to _list_visible_memories

* fix: defense-in-depth guard for empty scope_id on search/list

Copilot review: if scope is 'user' or 'workstream' with empty
scope_id, the storage query returns all memories in that scope
across all users/workstreams.  The prepare step already validates
via _validate_scope, but add exec-level guard to reject scoped
queries with empty scope_id as defense-in-depth.

- Tool count 17/18 → 19 across tools.md, architecture.md, and
  PlantUML diagrams (02-package-structure, 05-tool-pipeline)
- Add diff_file tool documentation section
- Document new params: bash timeout + stop_on_error, write_file
  mode (append), edit_file replace_all
- Add diff_file, watch, skill to tool pipeline dispatch table
- Regenerate diagram PNGs

* fix: remove slim dpkg exclusion so man pages are actually installed

The python:3.14-slim image excludes /usr/share/man/* via dpkg config.
man-db was installed but had no pages to serve.  Remove the exclusion
before installing packages, and add manpages package for coreutils
documentation.  Dropped info (rarely used, man covers the same).

* fix: redact DB connection strings and URL-based secrets in output guard

The output redactor missed TURNSTONE_DB_URL and DATABASE_URL because
the env secret key pattern only matched SECRET/TOKEN/PASSWORD/KEY,
not URL-based credential keys.  Also the connection string regex
didn't cover the postgresql+psycopg:// scheme used by psycopg3.

- Add DATABASE_URL, TURNSTONE_DB_URL, DB_URL to explicit env key matches
- Add psycopg and sqlite to connection string scheme pattern

* fix: address Copilot review on docs — tool names, counts, approval

- Fix remaining 17→19 count in tools.md execution pipeline section
- Dispatch table: task→task_agent, plan→plan_agent (match actual names)
- Dispatch table: header clarifies "19 built-in + tool_search"
- watch/skill: show conditional approval (create only / load only)
- Regenerate pipeline diagram PNG

* refactor: add is_error to on_tool_result protocol, remove text heuristics

Add is_error keyword arg to SessionUI.on_tool_result() so tools
report errors structurally. Server and JS client no longer guess
from output text prefixes — each tool sets the flag at the source.

Bash tool: exit code >= 2 is error, exit code 1 is ambiguous (grep
no-match). History reconstruction keeps text heuristic as fallback
for pre-migration data.

Update SDKs (Python + TypeScript), test mocks, docs, and diagrams.

* fix: infinite recursion in _report_tool_result, signal exits, stale docs

* fix: add _tool_error_flags to test_load_skill ChatSession stubs

Patrick Buckley 4f6ef13ce9 fix: cancel button race condition with stream abort and force cancel (#202)
The cancel endpoint emitted a 'cancelled' SSE event before the worker
thread terminated. The frontend transitioned to "send" mode prematurely,
so the next send got rejected with "Already processing a request."

Backend:
- Providers expose SDK stream handle via cancel_ref parameter so
  cancel() can close the HTTP connection and unblock iteration
- Generation counter prevents orphaned threads from mutating messages
  or clearing cancel state after force cancel
- _check_cancelled() added between retry attempts in _try_stream
- Server polls (async, non-blocking) for cancelled worker to exit
- Force cancel (force:true) abandons stuck worker, keeps cancel event
  set so subprocesses are killed, guards against spurious SSE events

Frontend:
- 'cancelled' shows "Cancelling..." then escalates to "Force Stop"
  after 2s for a harder cancel that abandons the worker immediately
- 10s safety timeout auto-recovers if stream_end never arrives
- busy_error re-enables stop button instead of showing send
- Timeout cleanup in disconnectSSE, stream_end, and force .then()
- Layout shift prevention (min-width, white-space: nowrap)
- aria-label updates for accessibility

Tests:
- 7 new tests: stream close, error suppression, cancel_ref population,
  transport error conversion, non-cancel exception propagation, retry
  cancellation check

Patrick Buckley 037308f3b1 fix: propagate user identity through console proxy
Console proxy previously used a fixed service identity (console-proxy)
with full {read,write,approve} scopes for all proxied requests, losing
the real user's identity at the proxy boundary. Now mints per-request
short-lived JWTs carrying the authenticated user's actual user_id,
scopes, and permissions so upstream servers record correct audit
attribution and enforce scope narrowing as defense in depth.

Patrick Buckley 414eb52d67 feat: raise scaling limits for 1000-node clusters (#129)
* feat: raise scaling limits for 1000-node clusters

Raise hardcoded limits throughout the codebase so clusters up to 1000
nodes work without configuration changes.

Scaling limits:
- max_workstreams default 10 → 50 (configurable via settings)
- Console fan-out concurrency 50 → 200 (configurable: cluster.node_fan_out_limit)
- MCP max servers 50 → 200 (configurable: cluster.mcp_max_servers)
- Console SSE queue 500 → 2000, server global SSE queue 500 → 1000
- httpx proxy pool: explicit max_connections on both proxy clients
- PostgreSQL pool 5+10 → 2+3 per process (right-sized for short-burst queries)
- Redis pool: explicit max_connections=200 on both sync and async brokers

Performance optimizations:
- Redis list_nodes(): replace N+1 SCAN+GET with SCAN+MGET
- Collector poll: raise thread pool to 200 (matches fan-out limit)
- Server SSE: dedicated ThreadPoolExecutor(200) for queue polling
- Fan-out: new get_all_nodes() removes hardcoded limit=1000 ceiling

Bug fixes:
- Settings reload notification was silently failing (called .get() on tuple)
- Watch fan-out only queried 500 nodes instead of full cluster

New cluster settings (configurable via admin Settings tab):
- cluster.node_fan_out_limit (default 200, range 10-1000)
- cluster.mcp_max_servers (default 200, range 1-2000)

Adds docs/pgbouncer.md for PostgreSQL connection pooling at scale.
Adds ddgStressCluster compose profile (100 nodes, 10 groups of 10).
Updates architecture, console, docker, settings, and API reference docs.

* fix: add image tag to compose anchors to avoid redundant builds

All cluster/stress services inherit `build:` from the anchor, causing
Docker to attempt 200+ separate builds. Adding `image: turnstone:local`
means Docker builds once and all services reuse the cached image.

* fix: address Copilot review feedback on scaling PR

- Remove magic number in get_all_nodes (limit=None instead of 2**31)
- Size httpx proxy pool from fan-out limit setting (not hardcoded 250)
- Cap cluster.node_fan_out_limit max_value to 500, mark restart_required
- Convert _publish_config_change from sync to async (was blocking event loop)
- Use shutdown(wait=True, cancel_futures=True) for SSE executor

* fix: add PostgreSQL env vars to cluster bridge anchor

Bridges initialize storage for auth/migrations but the bridge anchor
was missing TURNSTONE_DB_BACKEND and TURNSTONE_DB_URL, causing all
bridges to fall back to SQLite. With 100 bridges sharing the same
volume, concurrent SQLite migrations corrupt the database.

* fix: address Copilot round 2 + PG connection exhaustion at startup

Copilot feedback:
- Raise cluster.node_fan_out_limit max_value to 1000 (matches target)
- Cache fan-out limit on app.state at startup instead of re-reading DB
  per request (pool and semaphore now use the same value consistently)
- Remove unused params from _publish_config_change

Stress cluster fix:
- Raise PG max_connections to 300 (configurable via POSTGRES_MAX_CONNECTIONS)
  to handle 200 processes connecting simultaneously at startup
- Bump PG shared_buffers to 128MB and memory limit to 1G to match
- Add DB env vars to production bridge service

* fix readme

* fix: startup resilience for large clusters

Server no longer crashes when LLM backend is unreachable at startup.
detect_model() accepts fatal=False, returning (None, None) so the
server starts in degraded mode with circuit breaker open. The health
monitor will detect when the backend becomes available.

Migration runner retries with jittered exponential backoff (up to 10
attempts) when PostgreSQL rejects connections during startup stampedes.

Collector httpx pool sized to match poll workers (was using default of
100 connections with 200 workers).

Also addresses Copilot round 2:
- Raise cluster.node_fan_out_limit max_value to 1000
- Cache fan-out limit on app.state at startup
- Remove unused params from _publish_config_change
- Add DB env vars to production bridge service

* fix: replace silent error suppression with structured logging

Audit and fix 30+ instances of silently swallowed exceptions across 8
files. No-raise contracts are preserved — all changes add logging
while keeping the same return-value behavior.

memory.py (26 changes):
  Every storage operation now logs on failure. Previously the entire
  persistence facade had zero logging — messages, workstream state,
  and structured memories could silently stop being saved.

server.py:
  Usage recording failures now log at warning (was pass).
  Global SSE fan-out errors log at debug (was pass).

console/server.py:
  Config reload notification logs per-node failures at warning.
  Settings read fallbacks log at warning with the default value used.

auth.py:
  User existence check logs at warning (was pass).
  Setup rollback failures log at error (was suppress).
  OIDC state cleanup logs at debug (was suppress).

mcp_client.py:
  DB-managed MCP server list failure logs at warning (was pass).

collector.py:
  Node poll failure upgraded from debug to warning with exc_info.
  Health fetch failure logs at debug with exc_info (was silent).

bridge.py:
  Best-effort plan rejection logs at warning (was suppress).
  Malformed SSE data logs at debug (was suppress).

session.py:
  Tool output UI callback failure logs at debug (was suppress).

* fix: stagger collector poll with deterministic per-node jitter

Each node gets a stable offset within the first half of the poll
interval, derived from hashing the node_id against a Mersenne prime
(2^31 - 1). This spreads HTTP requests across the cycle instead of
firing all 100+ at the same instant.

Also raises poll interval from 10s to 15s and HTTP timeout from 5s
to 30s for large-cluster resilience.

* fix: add startup jitter to bridge heartbeat and health monitor probe

Bridge heartbeat: deterministic per-node jitter (from node_id hash)
spreads initial registration across the first quarter of the heartbeat
TTL. At 100 bridges with 60s TTL, heartbeats spread across 15s instead
of all firing at T=0.

Health monitor probe: deterministic per-process jitter (from PID hash)
spreads initial LLM backend probes across half the probe interval. At
100 servers with 30s interval, probes spread across 15s instead of all
hitting the LLM at T=30.

Both use the same Mersenne prime hashing approach as the collector poll
jitter for consistency.

* fix: split collector httpx timeout and raise keepalive pool

Use separate connect/read/write/pool timeouts instead of a single 30s
for all phases. Raise keepalive connections from 50 to 200 so the
collector reuses TCP connections across poll cycles instead of
constantly tearing down and re-establishing them.

* fix: narrow detect_model return type for CLI and eval callers

detect_model() now returns tuple[str | None, int | None] to support
fatal=False. CLI and eval always use fatal=True (the default), which
guarantees a non-None model or SystemExit. Add assert to narrow the
type for mypy.

Patrick Buckley dc464ac313 feat: Agent Skills standard compliance + frontend spec fields
Brings skills implementation into full compliance with agentskills.io:

Parser:
- Read `allowed-tools` (hyphenated, standard) only; stored as
  `allowed_tools` internally — no underscore fallback
- Reject consecutive hyphens in skill names
- Extract author/version from standard `metadata:` map with top-level
  fallback; null-safe (no "None" string for bare YAML keys)
- Truncate description at 1024 chars, compatibility at 500 chars (spec
  caps) with log warnings
- Lenient parsing mode (lenient=True) for cross-client import: sanitizes
  names, returns None on skip, malformed-YAML colon-value retry
- Type overloads: strict mode returns ParsedSkill, lenient returns
  ParsedSkill | None

Session:
- `<available-skills>` XML catalog in system messages for
  activation="search" skills (disabled ones filtered out, capped at 30)

Tool rename:
- `load_skill` tool → `skill` (JSON, session preparers/executors,
  approval labels, tests, docs)

Storage (migration 023):
- Add `license` and `compatibility` columns to prompt_templates
- skill_license / compatibility params on create_prompt_template across
  protocol, SQLite, PostgreSQL backends
- Add to SKILL_MUTABLE for update_prompt_template

API + server:
- SkillInfo, CreateSkillRequest, UpdateSkillRequest: license +
  compatibility fields
- Create/update/install endpoints extract and persist both fields
- Install endpoint maps parsed.license + parsed.compatibility from
  imported SKILL.md (previously discarded)
- _skill_to_response() includes both fields

Admin UI:
- Create + edit modals: version, license, compatibility fields
- Readonly (imported) skills: "edit" → "view" button, modal title
  "View Skill", all fields disabled, Save hidden, Cancel → "Close",
  collapsibles auto-expand, focus on Close button
- :disabled CSS for dark-theme modal inputs (bg-highlight, cursor
  not-allowed, dimmed text)
- Fix addEventListener stacking on auto-approve checkboxes → .onchange

SDK: license + compatibility on SkillInfo, CreateSkillRequest,
UpdateSkillRequest TypeScript interfaces

* feat: load_skill built-in tool — model-driven skill discovery and activation

Two-action tool: 'search' finds skills by multi-word query with substring
matching on name/description/tags/category (auto-approved, read-only);
'load' activates a skill by name via set_skill() (requires approval).

Guards: filters disabled skills from search + load; short-circuits when
skill is already active; approval_label includes skill name for granular
tool policies (load_skill__<name>); main session only (excluded from
sub-agents). Logs storage errors in search path.

25 tests covering registration, preparer validation, executor logic,
disabled/already-active edge cases, multi-word queries, approval labels.

* refactor: use BM25 relevance ranking for load_skill search

Replace substring matching with BM25Index from turnstone/core/bm25.py,
matching the pattern used by memory relevance and tool search. Handles
multi-word queries, term frequency, and document length normalization.

* fix: address copilot review — BM25 tags parsing, primary_key, test cleanup

- Parse JSON tags into space-separated text before BM25 indexing so
  individual tag terms match queries (was passing raw '["foo","bar"]')
- Add primary_key: "name" to load_skill.json for PRIMARY_KEY_MAP
- Remove dead resolve_workstream patch from test helper
- Update diagram: "substring match" → "BM25 ranking"

Patrick Buckley c28bfc1e58 feat: skill discovery — search and install skills from external sources (#111)
* feat: skill discovery — search and install skills from external sources

Add discovery UI and API for finding and installing skills from
skills.sh registries and GitHub repositories with one-click install,
SKILL.md frontmatter parsing, and security scan integration.

Core modules:
- skill_parser.py: ParsedSkill dataclass, parse_skill_md() with YAML
  frontmatter support (Anthropic + Hermes tag formats), name validation
- skill_sources.py: SkillsShClient (async search + resolve),
  fetch_skill_from_github (SKILL.md + bundled resource fetching with
  256KB cap, text extension filter, GitHub API tree traversal)

API:
- GET /v1/api/admin/skills/discover — search with installed annotation
  and scan_status for installed skills
- POST /v1/api/admin/skills/install — fetch, parse, duplicate check,
  create with origin="source" readonly=true, store resources, audit

Also fixes pre-existing bug where _skill_to_response omitted scan_status,
scan_report, scan_version fields — scan tier badges in the installed
skills table were silently empty despite data existing in storage.

Admin UI: pill toggle (Installed/Discover), discovery cards with scan
tier badges, GitHub import modal with proper focus trap/Escape/backdrop,
scoped selectors preventing MCP↔Skills cross-tab state corruption.

SDK: discover_skills() + install_skill() on Python (async+sync) and
TypeScript console clients.

48 new tests across 3 test files. All 2632 tests pass.

* fix: address copilot review — 404 vs 502, O(n) lookups, branch fallback

- SkillNotFoundError subclass: install returns 404 when SKILL.md is
  missing, 502 only for connectivity/upstream errors
- get_skill_by_source_url() + list_installed_skill_urls(): indexed
  storage lookups replace O(n) full-table scans with content blobs
- Default branch fallback: tries main then master when URL doesn't
  specify a branch
- Path normalization: strip trailing slash once, remove redundant
  candidate
- SDK install_skill() returns typed SkillInfo with response_model
- Tree size guard: skip resource tree if response >2MB

* feat: output guard data pipeline — persist assessments, SSE events, admin UI

Complete the output guard pipeline: persist assessments for v2 calibration,
surface warnings in every UI layer, and add scan badges to admin skills tab.

Storage: migration 022 adds output_assessments table (flags, risk_level,
annotations, output_length, redacted — raw output never stored) and
scan_version column on prompt_templates. Three new protocol methods with
SQLite + PostgreSQL implementations.

Server/CLI: on_output_warning now persists assessments fire-and-forget.
CLI shows flags, annotations, and redaction notice. Session emits on_info
warning when high/critical scan_status skill is loaded.

MQ: OutputWarningEvent dataclass + bridge SSE forwarding.

Web UI: output_warning SSE handler with inline warning rendering
(role="alert" for accessibility), semantic risk colors.

Console admin: scan badges on skills list (dedicated scope-scan-* CSS with
green/yellow/red risk vocabulary), scan report breakdown in edit modal with
4-axis scores, POST /admin/skills/{id}/rescan endpoint, GET
/admin/output-assessments endpoint with date-filtered pagination.

Security fixes: ReDoS in connection string regex ([^@\s]+ → [^:@\s]+),
negative limit bypass in all admin endpoints (max(1, ...)), to_dict()
excludes sanitized output by default.

False-positive fixes: credentials pattern anchored to path context,
env secret key check restricted to key portion only.

* fix: address PR #110 review — list redaction, test fixture, OpenAPI snapshot

Per-part redaction: evaluate each text part independently in structured
output instead of joining all parts and replacing only the first one.

Fix test annotations default from "{}" to "[]" matching schema.

Regenerate TypeScript OpenAPI snapshots for new admin endpoints.

Patrick Buckley 5378b33641 feat: output guard — evaluate tool results before they enter context (#109)
* feat: output guard — evaluate tool results before they enter context

Add turnstone/core/output_guard.py — a time-budgeted heuristic that
evaluates tool execution results after execution but before they
enter the conversation context window.

Priority-ordered detection (5s budget, highest priority first):
1. Prompt injection: override phrases, role injection, instruction
   override markers, meta-injection patterns
2. Credential leakage: API keys (OpenAI/GitHub/AWS/Google), PEM
   private key blocks, connection strings, .env secret format
3. Encoded payloads: script data URIs, hex shellcode sequences
4. Adversarial URLs: cloud metadata endpoints, credential query params
5. System info disclosure: private IPs, sensitive file paths

Annotates and optionally redacts (credentials → [REDACTED:<type>]).
Does NOT gate — surfaces warnings via on_output_warning callback.

Integration:
- Wired into session.py tool result loop via _evaluate_output()
- JudgeConfig gains output_guard + redact_secrets fields (both default true)
- SessionUI protocol gains on_output_warning callback
- 25 compiled regex patterns, pure function, no I/O

29 tests covering all detection categories, benign output false
positive checks, credential redaction, and time budget behavior.

* fix: address PR #109 review — protocol, config, and guard fixes

Copilot review feedback:
- Replace _CLEAN singleton with _clean() factory to prevent mutable
  shared state (OutputAssessment has list fields)
- Remove redundant second _CREDENTIAL_PATTERNS loop in _check_credentials
- Evaluate text parts of list outputs (images) not just string outputs
- Wire output_guard + redact_secrets through ConfigStore settings
  registry and _build_judge_config() so operators can configure via
  admin Settings tab
- Remove --no-output-guard CLI flag claim from docs (use Settings tab)

Typecheck fix:
- Add on_output_warning to all SessionUI implementations: NullUI
  (eval, 5 test files), WebUI (server — emits SSE event), TerminalUI
  (CLI — ANSI colored warning), RecordingUI, FakeUI

Patrick Buckley f05e6bddad feat(judge): enrich heuristic rules from 23 to 36 (#107)
* feat(judge): enrich heuristic rules from 23 to 36

Add 13 new pattern-based rules to the intent validation heuristic,
calibrated from analysis of 25K public agent skill security audits
across three independent auditors.

New critical: download-then-execute chains.
New high: browser+data export, transitive installs from untrusted
sources, control plane mutations (crontab, systemctl).
New medium: content ingestion pipelines (curl|python3), interpreter
execution (python3 script.py), cloud CLI mutations (az/gcloud/aws/
kubectl/terraform create/delete/destroy).
New low: tool_search, read_resource, web_search.

Fixes: crontab -l no longer false-positives, systemctl stop/disable
now flagged, az/gcloud subcommand patterns work correctly.

* fix(judge): address PR #107 review feedback

- content-ingestion: narrow second pattern to specific interpreters/
  processors (python3, node, ruby, perl, php, jq) instead of any word.
  Prevents false positives on read-only downstream (wget -O - | head).
- cloud-infra-mutation: split kubectl into its own pattern with specific
  verbs (apply, create, delete, scale, rollout, drain, cordon) to avoid
  false positive on resource types (kubectl get deploy).
- cloud-infra-mutation: split terraform/pulumi to specific verbs only
  (apply, destroy, import) — terraform plan no longer matches.
- control-plane-mutation: exclude -h and -V flags from crontab pattern
  alongside existing -l exclusion.
- Add 35 heuristic rule tests covering all 13 new rules with positive
  matches and negative (false-positive prevention) cases.

Patrick Buckley 75eda9a096 feat: unified skills system — merge prompt templates + workstream tem… (#106)
* feat: unified skills system — merge prompt templates + workstream templates

Evolves prompt_templates into a first-class skills entity and merges
workstream templates into the same model, collapsing two concepts into
one.

Migration 021: 21 new columns on prompt_templates (skills metadata,
security scan fields, session config from WS templates), skill_resources
table for bundled files, skill_versions table for auto-snapshot version
history. Data migration converts existing WS templates into skills with
name collision handling, migrates version history, renames workstreams
and scheduled_tasks columns, cleans orphaned permissions, drops old
tables.

Key changes:
- All public interfaces renamed: templates → skills (API, CLI, SDK, UI)
- Session config (model, temperature, token_budget, auto_approve, etc.)
  now lives on the skill and is applied at workstream creation
- /skill slash command, set_skill() API, --skill CLI flag
- BM25 skill search via SkillSearchManager for activation="search" skills
- Admin UI: Skills tab with collapsible Session Config section,
  description subtitles, activation/origin/MCP badges, pagination
- Shared validation helper (_parse_skill_session_config) for DRY CRUD
- Version history with auto-snapshot on every edit + API endpoint
- Cascade delete (resources + versions) on skill removal
- Security: range validation, activation allowlist, fail-closed enabled
  check, duplicate name 409, readonly guard, JSON validation
- 77 new tests across storage, runtime, search, API integration, and
  migration behavior verification (2521 total)

* fix: address Copilot review + rename admin.templates → admin.skills

- Skip skill lookup when resume_ws is set (avoids spurious 400)
- Fix _applied_skill_version mismatch (1 in both workstreams table and session)
- Remove stale template field from MQ protocol diagram
- Rename admin.templates permission to admin.skills everywhere (runtime,
  frontend, tests, docs) with migration step for persisted role data
- Fix stale /api/templates references in docs and diagrams
- Update docstrings/comments for skills terminology

* fix: address Copilot round 2 — skill version lineage + stale doc refs

- Compute actual skill version from skill_versions count (not hardcoded 1)
- Use same version in both workstreams table and session metadata
- Fix response payload example: "templates" → "skills" key
- Fix "Each template summary" → "Each skill summary"

Patrick Buckley 80e1924d7f feat: enable prompt caching for Anthropic and OpenAI providers (#104)
* feat: enable prompt caching for Anthropic and OpenAI providers

Activate automatic prompt caching on both LLM providers to reduce input
token costs on multi-turn conversations. Anthropic gets cache_control:
ephemeral (90% savings on cache hits), OpenAI GPT-5.x gets 24h extended
cache retention (free). Cache metrics flow end-to-end through the entire
data pipeline: provider → session → server SSE → MQ protocol → storage →
Prometheus metrics → admin Usage tab.

- AnthropicProvider: top-level cache_control on all requests, extract
  cache_creation_input_tokens and cache_read_input_tokens from streaming
  and non-streaming responses
- OpenAIProvider: prompt_cache_retention=24h for GPT-5.x, extract
  cached_tokens from usage.prompt_tokens_details
- UsageInfo: new cache_creation_tokens and cache_read_tokens fields
- Migration 020: add cache columns to usage_events table
- Storage: record_usage_event and query_usage updated (sqlite + pg)
- Metrics: turnstone_tokens_total{type="cache_creation|cache_read"}
- Server: on_status passes cache tokens to SSE, storage, and metrics
- MQ: StatusEvent carries cache fields through bridge
- SDKs: Python and TypeScript StatusEvent types updated
- OpenAPI: UsageBreakdownItem schema includes cache fields
- Console UI: Usage tab shows cache write/read as secondary readouts
  with visual separator, dimmed when zero
- 16 new tests, docs and 3 diagrams updated

* fix: address Copilot review feedback

- Fix MQ protocol diagram clipping by switching to vertical package
  layout (inbound on top, outbound below) with package aliases
- Regenerate OpenAPI snapshots to include cache_creation_tokens and
  cache_read_tokens on UsageBreakdownItem
- Replace fragile MagicMock(spec=[]) + del pattern with
  types.SimpleNamespace in cache metrics missing-attributes test

Patrick Buckley 50544c0d1b feat: MCP Registry integration — discover and install servers from the official registry
Backend: standalone MCPRegistryClient (httpx async) queries the official MCP
Registry API (registry.modelcontextprotocol.io, v0.1). Two new console admin
endpoints: GET /v1/api/admin/mcp-registry/search (proxy with installed-status
annotation, dedup, uninstallable server filtering) and POST
/v1/api/admin/mcp-registry/install (auto-reloads all cluster nodes). Migration
019 adds registry_name/version/meta columns to mcp_servers with partial unique
index. Configurable registry URL via mcp.registry_url setting for
enterprise/private registries. resolve_install_config() handles both remote
(streamable-http) and package (npm→npx, pypi→uvx) installs. Pydantic models,
OpenAPI spec, Python + TypeScript SDK methods.

Frontend: unified MCP admin tab with Servers/Registry pill toggle (ARIA
tablist). Servers view: tri-state source badges (CONFIG/MANUAL/REGISTRY).
Registry view: search bar with type filter (remote/npm/pypi), auto-browse on
tab switch, result cards with source-type badges and repo links, one-click
install for zero-config remotes, install modal with dynamic form for servers
needing env vars/headers/URL variables. Package install warning banner.
Post-install status polling with connection/error feedback toasts. Trust
notice banner linking to the official registry.

Safety: 30s connect timeout on streamablehttp_client and session.initialize()
prevents hung connections from blocking the MCP event loop indefinitely.
Required-only headers in install config prevents empty auth headers from
causing silent 401s.

71 new tests (registry client, API endpoints, storage columns). Docs:
dedicated docs/mcp-registry.md, updated api-reference, architecture, console,
sdk, settings docs. Updated MCP architecture diagram.

Patrick Buckley e7743fd079 feat: per-tool "Always" approve instead of blanket auto-approve (#82)
* feat: per-tool "Always" approve instead of blanket auto-approve

Interactive "Always" button now adds specific tool names to
auto_approve_tools instead of setting blanket auto_approve=True.
Only the tool types in the current batch are auto-approved going
forward — new tool types still prompt for approval.

Server uses approval_label (with func_name fallback) matching the
existing approve_tools() lookup. CLI and bridge use func_name.
Budget override excluded from all paths.

UI: dashed border on Always button signals persistent action,
dynamic tooltip/badge show tool names, aria-label for screen
readers, focus-visible outline fix, overflow-wrap on badge.

Bridge: seeds with DEFAULT_SAFE_TOOLS on first "always" to avoid
losing existing safe-tool auto-approvals.

16 new tests (10 unit + 6 TestClient integration). Updated tool
pipeline diagram and docs.

* fix: address copilot review — filter errored items, hide Always on budget-only

- Server/bridge/JS: add `not it.get("error")` filter so policy-denied
  items aren't added to auto_approve_tools
- Hide Always button when no eligible tools (budget-override-only batch)
- Docs: clarify CLI/bridge use func_name (coarser MCP granularity)

Patrick Buckley 27349e1c13 refactor: move bridge content buffer to server-side single source of truth
Eliminate dual accumulation by piggybacking assistant response text on
the server's ws_state:idle SSE event.  The bridge no longer maintains
its own _ws_content_buffer — it reads content directly from the idle
event and passes it through to TurnCompleteEvent unchanged.

Server-side: WebUI accumulates tokens in on_content_token(), joins and
includes in the idle broadcast, then resets (with 256 KB cap).

Downstream consumers (Discord bidi DM forwarding, catch-up) are
unaffected — TurnCompleteEvent.content is still populated.

Patrick Buckley 20df7b3034 feat: OIDC SSO authentication with PKCE, auto-provisioning, and role … (#71)
* feat: OIDC SSO authentication with PKCE, auto-provisioning, and role mapping

Add OpenID Connect as a fourth authentication method, enabling single sign-on
via any OIDC provider (Okta, Azure AD, Google, Keycloak). Opt-in via env vars
(TURNSTONE_OIDC_ISSUER, CLIENT_ID, CLIENT_SECRET).

Security:
- Authorization Code Flow with PKCE (S256)
- State/nonce parameters with database-backed pending store (multi-node safe)
- JWKS signature validation with async fetch + key rotation retry
- Algorithm allowlist from JWKS key (not token header) prevents confusion
- Identity matching exclusively by (issuer, sub) — prevents account takeover
- password_enabled=false enforced server-side, not just UI
- Rate limiting on both authorize and callback endpoints
- OIDC users get "!oidc" password sentinel (bcrypt rejects naturally)
- ID token validated for iss, aud, exp, nonce

Features:
- Auto-provisioning with username deduplication on first login
- Claim-based role mapping with IdP demotion propagation (revokes stale roles)
- "Continue with [Provider]" SSO button on login page
- OIDC-only mode hides password form
- Setup wizard required before OIDC login (admin bootstrap)

Storage: migration 018 (oidc_identities + oidc_pending_states tables),
8 new protocol methods on both SQLite and PostgreSQL backends.
66 new tests (2273 total).

* fix: address PR #71 review feedback (18 items)

Bugs fixed:
- OIDC success redirect now fetches permissions via new /auth/whoami
  endpoint before completing login (fixes permission-gating in UI)
- Remove double decodeURIComponent on oidc_error (URLSearchParams
  already decodes; extra call throws on stray %)
- Authorize rate limiter returns redirect instead of JSON 429
  (endpoint reached via browser navigation, not fetch)
- Lazy JWKS fetch in callback when startup discovery failed (IdP
  recovery without restart)
- Startup exception handlers now log with exc_info=True
- PostgreSQL pop_oidc_pending_state uses DELETE...RETURNING for
  true atomicity (eliminates TOCTOU)

Behavior:
- New OIDC users without role mapping get builtin-viewer by default
  (assigned_by="oidc-default", not revoked by role sync)

Documentation fixes:
- Role mapping: sync semantics (add + revoke stale), not "additive only"
- PASSWORD_ENABLED=false blocks ALL password logins including admin
- Algorithm: asymmetric allowlist, not per-key derivation
- PlantUML diagram updated for role revocation

API spec fixes:
- Removed error_codes=[302] from callback (302 is success redirect)
- Added /auth/whoami to both server + console specs
- Regenerated TypeScript SDK OpenAPI snapshots (23 + 51 paths)

* fix: address PR #71 round 2 review feedback (10 items)

Rate limiting:
- Authorize endpoint now calls record() after check() so the rate
  limiter actually counts attempts (was a no-op before)

OIDC resilience:
- Split startup try/except: discovery failure disables OIDC, JWKS
  prefetch failure leaves OIDC enabled for lazy retry on first login
- JWKS unavailable message changed to "temporarily unavailable"
  (was misleadingly "not configured")
- create_oidc_pending_state raises on collision instead of OR IGNORE
  (prevents silent insert drop on state collision)
- SQLite pop_oidc_pending_state uses BEGIN IMMEDIATE for write lock
  (eliminates TOCTOU race)

Frontend:
- OIDC error display deferred 300ms so showLogin()'s async status
  fetch doesn't clear it via _switchMode → _clearError

API spec:
- OIDC authorize/callback endpoints now declare response_code=302
- Added AuthWhoamiResponse Pydantic model for /auth/whoami
- Regenerated TypeScript SDK OpenAPI snapshots

Documentation:
- Diagram: JWKS "cached at startup, refreshed on-demand" (was "hourly")
- Added TODO(tech-debt) comments on Host header redirect_uri sites

* feat: prompt template tech debt — tests, read-only endpoints, double-load fix, server creation modal

Close test coverage gaps for prompt templates:
- Resume with deleted template: verifies graceful degradation (template_content=None, warning logged)
- Threading safety: concurrent set_template/init_system_messages with no race conditions
- Factory passthrough: template kwarg propagation through WorkstreamManager.create()

Add read-only template listing endpoints (read scope, no content exposed):
- GET /v1/api/templates — prompt template summaries (name, category, is_default, origin)
- GET /v1/api/ws-templates — enabled workstream template summaries (name, description, model)
- Available on both server and console; Python + TypeScript SDK methods added
- Console creation modal switched from admin endpoint to read-scope endpoint

Eliminate double-load inefficiency in workstream creation:
- Template validation moved before mgr.create() (no create-then-rollback on invalid template)
- template kwarg plumbed through WorkstreamManager.create() and session factory
- _SessionFactory Protocol added for proper mypy typing

Add workstream creation modal to server web UI:
- Name, model, template dropdown, ws_template/profile dropdown
- Instrument panel aesthetic: gradient top border, blur backdrop, amber accent
- Focus trap, Escape/Enter keyboard handling, loading state, error display
- WCAG AA contrast compliance, reduced-motion support

* fix: add list_ws_templates SDK methods + regenerate OpenAPI snapshots

Add list_ws_templates() to Python SDK (async + sync) and listWsTemplates()
to TypeScript SDK for the new GET /v1/api/ws-templates server endpoint.
Add WsTemplateSummary + ListWsTemplateSummaryResponse TypeScript types.
Regenerate openapi-server.json and openapi-console.json snapshots.

Addresses Copilot review feedback on PR #67.

* fix: skip template pre-validation when resuming a workstream

When resume_ws is set, the request's template field is irrelevant —
resume() restores the template from workstream_config. Pre-validating
a stale template name would incorrectly return 400 before the resume
even runs.

Extract markdown rendering from app.js into dedicated renderer.js with
full GFM support: tables (alignment, hover, striping), nested lists,
task list checkboxes, nested blockquotes, images (click-to-load for
privacy), and inline/display LaTeX math via self-hosted KaTeX 0.16.38.

Security: escape image/link URLs to prevent attribute injection, block

KaTeX error color override for WCAG AA contrast, reduced-motion support.

* fix: address code review — XSS hardening and list type splitting

- Escape all text through escapeHtml() at start of inlineMarkdown()
  so only renderer-generated tags appear in innerHTML (prevents raw
  HTML/script injection from LLM output)
- Replace inline onclick handler on image placeholders with data-*

* feat: Discord content catch-up + bidirectional notification replies (#64)

Two improvements to the Discord channel adapter:

1. Fix intermittent dropped responses caused by a race between the
   bridge's two independent SSE connections (global SSE detects idle
   before per-ws SSE delivers all content tokens). The bridge now
   accumulates content in _ws_content_buffer and attaches it to
   TurnCompleteEvent.content. The Discord bot uses this as a catch-up
   when streaming events were missed.

2. Bidirectional notification replies — when the notify tool sends a DM,
   the message is tracked with the originating ws_id. Users can reply to
   the DM and the reply is routed to the workstream. The response is
   forwarded back to the DM, with the response itself tracked for
   multi-turn conversations. Includes user identity verification,
   stale notification feedback, and FIFO-capped tracking (100 entries).

* fix: address Copilot review — re-insert on unlinked user, deque buffer

- Re-insert _notify_ws_map entry when resolve_user returns None so the
  user can retry after linking (same pattern as user-mismatch re-insert)
- Rename _MAX_CONTENT_BUFFER_BYTES → _MAX_CONTENT_BUFFER_CHARS (len()
  returns characters, not bytes)
- Use deque + running total for O(1) popleft instead of list.pop(0)

* feat: admin MCP Servers tab — database-backed MCP server management with live status

Add MCP Servers admin tab (14th tab, System group) for managing MCP server
definitions via the database instead of static JSON config files.

Storage: `mcp_servers` table (migration 016), 6 CRUD methods on both SQLite
and PostgreSQL backends, `MCP_SERVER_MUTABLE` field allowlist.

Config priority chain: DB rows (if any enabled) → CLI `--mcp-config` →
`mcp.config_path` setting → none. Nodes auto-load from DB on startup via
`load_mcp_config(storage=)`.

Hot-reload: `reconcile_sync(storage)` diffs running servers against DB —
adds missing, removes stale, reconnects changed. `_db_managed` set tracks
DB-sourced servers so config-file servers (MCP_CONFIG env) are never removed
by reconcile. Per-server `AsyncExitStack` for clean teardown.

Reload pattern: console writes to DB then signals nodes via
`POST /_internal/mcp-reload` (update by reference, no config payload).

Console admin API: 7 endpoints under `/v1/api/admin/mcp-servers` (CRUD +
reload + import), `admin.mcp` permission, secret masking (env/headers
replaced with *** unless ?reveal=true), audit log sanitization.

Unified view: tab merges DB-managed servers with config-sourced servers
detected on nodes. Config servers shown as read-only rows with "config"
badge — no edit/delete.

Admin UI: 7-column grid with magenta status dots, transport badges,
single-column create/edit modal, paste-based JSON import (mcpServers format),
detail modal with per-node status. Mobile 3-column collapse, reduced-motion
support, backdrop-click dismiss, focus trapping.

SDKs: 7 methods on Python (async+sync) and TypeScript SDKs.

Also fixes: Settings tab permission gate (admin.users → admin.settings),
_ALL_PERMISSIONS list in governance.js (5 missing permissions added),
_internal/mcp-reload added to APPROVE_PATHS.

Docs: architecture.md (14 tabs), api-reference.md (7 endpoints),
20-mcp-architecture.puml updated with admin-driven lifecycle.

66 new tests (2232 total).

* fix: address Copilot review feedback on MCP admin PR

- Docs: fix "merges both sources" → "first-match-wins priority" (architecture.md)
- Validation: require command for stdio, url for streamable-http transport

- Schema: add transport/command/url to McpServerStatus, source to McpServerDetail
- Thread safety: move all remove_server_sync mutations onto MCP event loop thread
- Regenerate OpenAPI JSON snapshots for TypeScript SDK

* feat: database-backed settings (ConfigStore) with admin API

Replace config.toml for non-bootstrap settings on the server with a
database-backed ConfigStore.  ~40 settings across model, session,
tools, server, mcp, ratelimit, health, judge, and memory sections are
now managed via the admin Settings API.  CLI flags for these settings
removed from the server entry point (CLI standalone tool unchanged).

Storage: system_settings table (migration 015) with composite PK
(key, node_id) for per-node overrides.  ON CONFLICT upsert in both
SQLite and PostgreSQL.  admin.settings permission granted to
builtin-admin role.

Settings registry (settings_registry.py): code-defined catalog of
all known settings with types, defaults, validation, descriptions.
Registry defaults aligned with previous argparse defaults.

ConfigStore (config_store.py): thread-safe in-memory cache loaded
from storage on init.  Lock-free reads via dict snapshot swap.
reload() for hot-reload via internal endpoint.

Secret settings (judge.api_key) blocked from write via admin API
(403) — must be configured via config.toml or env vars.

* fix: address PR review — config-reload scope, registry defaults, doc alignment

- config-reload endpoint requires approve scope (was write)
- config-reload handler is sync def (avoids blocking event loop)
- reasoning_effort passes empty string through (removes `or "medium"`)
- ratelimit.requests_per_second changed to float (matches RateLimiter)
- session.retention_days allows 0 (disable pruning)
- ratelimit.trusted_proxies added to registry + wired in server
- admin_list_settings filters to global settings only (no node_id ambiguity)
- admin_update_setting validates "value" key presence (400 if missing)
- Console config change fans out reload to nodes directly (no MQ dep)
- Docs aligned with actual API response shapes and masking ("***")

Patrick Buckley 67f43a7ee0 feat: [memory] REST API endpoints + SDK methods + docs (#56)
* feat: [memory] REST API endpoints + SDK methods + docs

Server API (4 endpoints):
- GET /v1/api/memories — list with type/scope/scope_id/limit filters
- POST /v1/api/memories — save (upsert) with validation
- POST /v1/api/memories/search — search by query (read scope)
- DELETE /v1/api/memories/{name} — delete by name+scope

Console admin API (4 endpoints):
- GET /v1/api/admin/memories — list all memories
- GET /v1/api/admin/memories/search — search with ?q= param
- GET /v1/api/admin/memories/{memory_id} — get by ID
- DELETE /v1/api/admin/memories/{memory_id} — delete by ID with audit

Storage: add delete_structured_memory_by_id, add mem_type filter to
count_structured_memories. Auth: memory DELETE requires write scope,
admin.memories permission added to valid set + builtin-admin role.

Python SDK: list_memories, save_memory, search_memories, delete_memory
on both server (async+sync) and console (async+sync) clients.

TypeScript SDK: matching methods + types on both clients.

Pydantic schemas with Literal type/scope validation, OpenAPI endpoint
specs on both servers. 33 endpoint tests + 8 auth scope tests.

Docs: docs/memory.md feature guide, api-reference.md endpoint docs,
23-memory-architecture.puml diagram.

Also fixes stray `total: int` on CreateChannelUserRequest.

* fix: [memory] address PR review — cross-user scope, schema types, snapshots

Security: user-scoped memory endpoints now bind scope_id to the
authenticated user's identity.  Providing a mismatched scope_id
returns 403, preventing cross-user memory access on all 4 server
endpoints.

Schema: MemoryInfo response uses MemoryType/MemoryScope Literals.
SearchMemoriesRequest uses filter Literals (empty string allowed).
Limit query params declare schema_type="integer" for correct OpenAPI.

Regenerate sdk/typescript/openapi-{server,console}.json snapshots.
Update count_structured_memories docstring for mem_type param.
Fix fallback response to use normalized name after save.

6 new security tests for user-scope access control.

* feat: structured memory system — typed/scoped memories with BM25 relevance and metacognitive prompting

Replace flat key-value memories table with structured_memories (migration 014).
Four memory types (user/project/feedback/reference), three scopes
(global/workstream/user). Consolidate remember/recall/forget into two tools:
memory (action-based: save/search/delete/list) and recall (conversation
history only).

BM25 relevance scoring (extracted to turnstone/core/bm25.py) selects top-5
memories for system message injection based on conversation context.
Metacognitive prompting injects ephemeral nudges after corrections, tool
denials, workstream resume, and completion signals.

Scope isolation enforced: system message injection and nudge counts filtered
to visible memories only (global + current workstream + authenticated user).
User scope requires authentication. Content capped at 32KB. ILIKE/LIKE
metacharacters escaped in both backends.

113 new tests (2053 total).

* fix: CI failure + copilot review feedback

- Fix time.monotonic() cooldown: use None sentinel instead of 0.0
  default (monotonic clock starts at boot, not epoch — fresh CI
  runners have uptime < 300s so cooldown check always triggered)
- Catch sa.exc.IntegrityError specifically in upsert instead of
  broad Exception (copilot review)
- Preserve existing description/type on upsert when caller doesn't
  explicitly set them (copilot review)
- Add last_accessed + access_count columns to schema/migration for
  future LRU/LFU eviction support

Patrick Buckley 09ea3d164d feat: intent validation v1 — advisory LLM judge for tool approvals (#50) (#50)
* feat: intent validation v1 — advisory LLM judge for tool approvals (#50)

Two-tier evaluation pipeline for non-auto-approved tool calls:
- Heuristic tier (instant): 23 pattern-based rules across 4 severity
  levels (critical/high/medium/low) with first-match-wins priority
- LLM judge tier (async): multi-turn evaluation with read_file/
  list_directory tool access, security-hardened path blocking, forcing
  message on final turn, four-stage JSON parsing with retry nudge

Progressive UI: heuristic verdict badge + judge spinner, LLM verdict
upgrade via intent_verdict SSE event, glow on action buttons. Verdict
persisted to intent_verdicts table for audit. Prometheus metrics for
verdict counts and LLM latency. Enabled by default (--no-judge to opt
out). 132 new tests (1938 total).

Integration: session, server/WebUI, CLI, MQ bridge, console admin API,
Discord channel adapter. Config via [judge] in config.toml or CLI flags.

* fix: address PR #50 Copilot review feedback

- Fix double JSON encoding of func_args in both heuristic and LLM
  verdict persistence paths — use pre-serialized string from verdict
- Fix confidence 0.0 treated as falsy in channel verdict formatter
- Fix timestamp format inconsistency in storage backends (isoformat
  vs strftime) — now uses strftime consistently
- Add on_intent_verdict to eval.py NullUI (mypy fix)
- Fix late verdict after approval resolved — store last decision and
  apply immediately to late-arriving verdicts
- Add permission rollback to migration 012 downgrade
- Update docs to reflect judge enabled by default
- Document confidence_threshold as reserved for v2

* fix: judge per-call timeout and credential recon heuristic

- Wrap create_completion() in ThreadPoolExecutor with per-call timeout
  to prevent indefinite hangs on slow local models. On timeout, replace
  the executor so subsequent batch items don't queue behind lingering
  API calls
- Add IntentJudge.shutdown() and wire into session.close() for cleanup
- Add credential-recon heuristic rule: /etc/passwd, /etc/shadow,
  /etc/master.passwd access flagged as HIGH/review (reconnaissance
  pattern even though the command itself is read-only)
- 3 new tests for credential file access patterns

* fix: denied/blocked tool calls show correct badge on resume

- _build_history() detects denied results ("Denied by user") and
  blocked results ("Blocked") and propagates denied flag to parent
  assistant entry for frontend consumption
- Frontend history replay uses denied flag for badge-denied class
  instead of hardcoding badge-approved for all historical tool calls
- Denial feedback always prefixed with "Denied by user:" so content
  detection works with custom user feedback
- Denied tools visually muted (opacity 0.55, muted tool name)
- role="status" on all approval badge elements (accessibility)
- Broadened "Blocked" prefix match (catches "Blocked by tool policy")

Patrick Buckley 02d9c5c797 feat: workstream templates — behavioral profiles for workstream creation (#49)
* feat: workstream templates — behavioral profiles for workstream creation

Workstream templates define the complete configuration for workstream
creation: system prompt, model, auto-approve policy, per-tool
auto-approve, temperature, reasoning effort, max tokens, agent max
turns, token budget, and completion notifications. Applied once at
creation time (snapshot, not live binding). Auto-versioning captures
pre-update state on every edit.

Schema & storage:
- workstream_templates + workstream_template_versions tables (migration 011)
- ws_template_id/ws_template_version columns on workstreams table
- ws_template column on scheduled_tasks table
- Full CRUD + versioning on SQLite and PostgreSQL backends
- prompt_template_hash (SHA-256) for drift detection

Runtime:
- Template resolution before mgr.create() for model override
- Post-creation settings application (prompt, temperature, approval, budget)
- Token budget enforcement in session.send() — 80% warning, approval gate
  at 100% via __budget_override__ synthetic tool
- WebUI.auto_approve_tools server-side per-tool auto-approve
- Prompt template drift detection (hash comparison, log warning on mismatch)

Integration:
- ws_template field on CreateWorkstreamMessage, bridge, channel router,
  scheduler dispatch, MQ client
- Console admin "WS Templates" tab (11th) with CRUD, version history modal
- Profile dropdown on workstream creation modal
- WS template dropdown on scheduler create/edit modals
- Prompt template name validation on ws_template create/update
- 7 console admin API endpoints + read-only summary endpoint
- Full OpenAPI spec entries in console_spec.py
- Python SDK (sync + async) and TypeScript SDK methods
- Pydantic schemas for all request/response models

Docs & diagrams:
- New 21-ws-template-architecture.puml sequence diagram
- Updated governance, storage, MQ protocol diagrams + PNGs
- Updated architecture.md, governance.md, api-reference.md, console.md, sdk.md

48 new tests (1788 total). mypy clean. ruff clean.

* fix: address PR #49 review feedback

- auto_approve_tools uses approval_label (not just func_name) for
  consistency with tool policy evaluation
- inline system_prompt from ws_template persisted as
  _ws_template_system_prompt in workstream_config, restored on resume
  (previously lost because _template_content wasn't persisted)
- budget gate (__budget_override__) no longer bypassed by blanket
  auto_approve — requires explicit approval or tool policy allow
- diagram 21 field list corrected (removed tool_search/threshold,
  added prompt_template_hash/notify_on_complete)

* fix: address PR #49 review feedback (round 2)

- Grant admin.ws_templates permission in migration 011 (tab was hidden)
- Center WS template modals and fix radio button alignment
- Skip template validation when ws_template overrides prompt
- Guard against empty version snapshots on no-op updates
- Replace setTimeout race with Promise chain in schedule ws_template select
- Validate numeric fields in admin create/update handlers (400 not 500)
- Add ws_template to TypeScript OpenAPI specs
- Use typed Pydantic response models in SDK ws_template methods

Patrick Buckley 2f7f70825b feat: wire prompt templates into session startup with full creation-p… (#47)
* feat: wire prompt templates into session startup with full creation-path support

Prompt templates (prompt_templates table) now have runtime effect:

- is_default=true templates auto-apply as system message content,
  concatenated in name order before user instructions
- Per-workstream template selection via --template CLI flag, template
  field on POST /v1/api/workstreams/new, console creation modal dropdown,
  scheduled task config, and channel adapter config
- {{model}}, {{ws_id}}, {{node_id}} variable substitution via single-pass
  regex (prevents cross-variable injection)
- /template slash command for runtime switching, persisted across resume
- set_template() public API on ChatSession

Security hardening:
- MCP sync resets is_default=False on content update (prevents compromised
  server from injecting defaults)
- 32KB content cap on template create/update + defensive truncation
- Template existence validation returns 400 before workstream creation
- Single-pass regex eliminates cross-variable expansion

Template field plumbed through all creation paths: CLI, server API, MQ
protocol/bridge, console backend, scheduler dispatch, channel router,
MQ client. Migration 010 adds template column to scheduled_tasks.

Frontend: console workstream modal template dropdown, scheduler
create/edit template field, governance template UI variables auto-detected
from content (read-only display replaces editable input). Focus trap and
Enter-key accessibility fixes in workstream modal.

Docs: governance.md template runtime section, api-reference.md template
field, governance + MCP architecture diagrams updated.

Python + TypeScript SDKs, Pydantic schemas all updated. 29 new tests.

* fix: address PR #47 review feedback

- Defer template validation until after resume_ws — a bad template name
  no longer 400s when resume would have ignored it anyway
- Add template field to OpenAPI JSON specs (openapi-server.json,
  openapi-console.json) for SDK/docs consistency
- Validate template existence in schedule create and update endpoints —
  reject unknown template names with 400 instead of allowing schedules
  that would silently fail at dispatch time

Patrick Buckley be165c1971 feat: MCP resource and prompt discovery with read_resource tool (#44)
* feat: MCP resource and prompt discovery with read_resource tool

Extends MCPClientManager with resource and prompt discovery alongside
existing tool support. Resources and prompts are discovered on connect,
cached per-server with copy-on-write rebuilds, and refreshed via push
notifications, periodic polling, or manual /mcp refresh.

New read_resource built-in tool reads MCP resources by URI. Requires
user approval (same as MCP tool calls) since resources are served by
external MCP servers. Resource catalog injected into system message
with XML delimiters. Error messages sanitized to prevent leaking
server internals to the model.

Prompt discovery stores prefixed names (mcp__server__prompt) and
exposes get_prompt_sync() for future use_prompt tool (Chunk D).

/mcp command now shows tools, resources, and prompts. Docs and
diagrams updated.

* feat: MCP prompt governance sync with origin tracking and readonly guards

Migration 009 adds origin, mcp_server, and readonly columns to
prompt_templates. MCP prompts discovered by MCPClientManager are
automatically synced into the governance table as read-only templates
with origin="mcp".

Sync engine handles: create on connect, update on prompt refresh,
delete when prompts are removed from server. Manual templates take
precedence on name collision (MCP prompt skipped with warning).

Admin API returns 403 on update/delete of readonly templates. Console
UI shows MCP origin badge and disables edit/delete buttons. Storage
backends gain get_prompt_template_by_name, list_prompt_templates_by_origin,
and delete_prompt_templates_by_server methods.

Also addresses PR #44 review feedback: concurrent.futures.TimeoutError
handling in sync dispatch, XML-escape resource catalog descriptions,
resource template entries excluded from _resource_map, URI collision
warnings, needs_periodic capability-aware computation, malformed JSON
primary key fallback for read_resource.

* feat: use_prompt tool, prompt catalog, and PR review hardening

New use_prompt built-in tool invokes MCP prompt templates by name,
expanding them into messages. Requires user approval (external MCP
servers). Prompt catalog injected into system message with XML
delimiters (up to 30 prompts, HTML-escaped).

Prompt listener registered in session for catalog rebuild on changes.

Addresses PR #44 review feedback:
- _init_system_messages() now uses copy-on-write (build locally,
  assign atomically) so background thread callbacks never see
  partial system messages
- sync_prompts_to_storage() serialized behind _sync_lock to prevent
  races between set_storage() (main thread) and MCP background thread
- shutdown() clears listener lists to release callback references

Docs and diagrams updated for 18 built-in tools.

* feat: granular tool policies for MCP resources, prompts, and tools

Policy evaluation now uses approval_label (falling back to func_name)
for fnmatch pattern matching, enabling fine-grained per-URI and
per-server policies:
- read_resource: mcp_resource__{normalized_uri}
- use_prompt: mcp__{server}__{prompt} (prefixed name)
- MCP tools: mcp__{server}__{tool} (was static "mcp_tool")

URI normalization resolves .. path segments to prevent traversal
bypasses in policy matching. Resource templates filtered from system
message catalog (not directly readable). use_prompt arguments
validated as dict with string coercion.

TypeScript SDK PromptTemplateInfo gains origin, mcp_server, readonly
fields. Governance docs updated with MCP policy patterns.

* feat: MCP visibility in server and console UIs

Server health endpoint includes mcp.servers, mcp.resources, mcp.prompts
counts. Server UI status bar shows magenta MCP indicator with tooltip.
Console cluster status bar shows MCP metrics with magenta LED dot.
Console node detail view shows per-node MCP summary. Console collector
aggregates MCP counts across nodes in overview.

Uses var(--magenta) design token with new --magenta-glow for theme
adaptation. ARIA roles on MCP status elements. Tooltips on console
MCP metric labels. Node MCP summary hidden on mobile (< 700px).

New diagram: 20-mcp-architecture.puml covering full MCP lifecycle
(connection, discovery, refresh, governance sync, policy, UI).

* fix: McpStatus in health schema, count properties, catalog name fidelity

Adds McpStatus model to HealthResponse (Python + TypeScript SDKs) so
typed clients see the mcp field from /health.

Addresses Copilot review feedback:
- resource_count/prompt_count properties avoid list allocation on
  /health and /metrics polls
- get_tools/resources/prompts return shallow-copied dicts to prevent
  callers from mutating internal cache
- Prompt names and arg names in system message catalog are NOT
  HTML-escaped (model must use exact strings in use_prompt calls);
  only descriptions are escaped

* fix: OpenAPI spec McpStatus + diagram approval column accuracy

Adds McpStatus schema and optional mcp field to HealthResponse in
openapi-server.json, matching the Python schema and TypeScript types.

Fixes tool pipeline diagram: math, web_fetch, web_search correctly
shown as auto-approve (not "Yes" for approval).

Patrick Buckley fd507c6a3c feat: generation cancellation — stop button, cancel API, cooperative … (#40)
* feat: generation cancellation — stop button, cancel API, cooperative cancel

Add cooperative cancellation via threading.Event on ChatSession. The cancel
signal is set from outside the worker thread (HTTP handler, MQ bridge, or
Escape key) and checked at defined checkpoints: per streaming chunk, before
tool execution, inside bash commands, and at each sub-agent turn.

Core: GenerationCancelled(BaseException) exception, cancel()/_check_cancelled()
methods, partial content preservation in _stream_response, clean rollback in
send() with idle state emission (no re-raise).

Server: POST /v1/api/cancel endpoint, CancelledEvent SSE emission, worker
thread safety net.

Frontend: Stop button (■ Stop) with send/stop swap via setBusy(), Escape key
shortcut, cancelled event handler. Accessible: aria-label, focus-visible
override, light theme contrast, non-color differentiation.

MQ: CancelMessage inbound type, bridge _handle_cancel routed handler.

SDK: cancel() on Python async+sync clients, CancelledEvent in Python+TypeScript
event registries, isCancelledEvent type guard.

OpenAPI: CancelRequest schema + endpoint spec.

Docs: API reference, architecture, SDK docs updated. Diagrams: conversation
turn, tool pipeline, MQ protocol, workstream states, SDK architecture.

* fix: address PR #40 review feedback

- setBusy() now resets stopBtn.disabled so stop button is re-enabled on
  next generation after a successful cancel
- Gate cancel side effects (resolve_approval, resolve_plan, cancelled SSE
  event) on worker_thread.is_alive() to avoid spurious events when idle
- Add /v1/api/cancel endpoint and CancelRequest schema to TypeScript
  openapi-server.json to keep it in sync with Python-generated spec
