Patrick Buckley e60c19befd fix(watch): harden nudge/wake delivery across eviction, cancel, and identity rebinds
Wake path:
- Denial metacog nudge moves to the tool channel so it drains with the
  denied tool batch instead of the next user-message seam.
- wake_workstream_if_pending: shared wake gate for watch fires on
  already-idle workstreams (no IDLE transition for the watcher to
  observe), wired as wake_fn at every set_watch_runner site via the
  shared _watch_fire_wake_fn helper (closes over the Workstream OBJECT
  — after eviction+restore an id-keyed manager lookup would miss).
- session_worker exit backstop re-runs the wake gate the moment worker
  ownership clears: IDLE fans out on the worker thread, so
  transition-time wakes always landed on the reuse path and no-op'd
  (the coordinator idle_children strand).
- deliver_wake_nudge_from_queue contains GenerationCancelled — it is
  the wake worker's run() closure and only Exception is caught
  downstream.

Watch delivery:
- Terminal fires that cannot reach their workstream are HELD and
  redelivered on min(interval, 60s) without re-running the command,
  bounded by MAX_DELIVERY_ATTEMPTS per cycle and the watch's own
  max_polls across cycles; the poll charge commits durably at hold
  time so restarts stay budget-bounded.
- Restore admission control: per-ws dedup + MAX_CONCURRENT_RESTORES
  cap, presence-only re-check under the lock, detection-only stall
  alerts (reclaiming a wedged admission would trade capped degradation
  for total poll-pool collapse).
- Permanent-vs-transient restore taxonomy: corrupt persona stamp and
  genuinely-missing history (confirmed by a raising storage probe —
  the resume loader swallows read blips into []) deactivate the watch
  immediately; everything else holds and retries.
- Cancel-race defense: delivery paths re-check is_watch_active before
  stashing/dispatching, cancel paths write the row BEFORE
  forget_terminal_dispatched, the HTTP cancel endpoint clears runner
  state, and a per-tick sweep bounds the residual stash-after-clear
  interleaving to one check_interval.
- Abandon/exhaustion commits are write-then-clear so storage that can
  read but not write retries the row write instead of re-running the
  command every cycle; the fresh-fire unrestorable path stashes before
  its deactivation write for the same reason.

Registry follows identity:
- The dispatch registry is keyed by _ws_id at registration time; every
  rebind now moves it: non-fork resume() and /new go through
  _follow_watch_registration (new key live before the old is removed,
  never stealing a registration another live session holds), removals
  are owner-checked so tearing down a watch-restore shell or a
  resumed-away session cannot unregister a live pane, the restore
  shell yields to a registration that appears mid-restore, CLI
  --resume registers after the successful resume, and both the open
  path and the detail-GET lazy rehydrate wire the registration.

Teardown gating and backpressure honesty:
- cleanup_session_ui marks ws._closed FIRST under ws._lock — every
  teardown path (close, close_idle, evict, delete, discard) funnels
  through it — and session_worker.send re-checks under the same lock,
  so a wake can never spawn a worker on a torn-down workstream.
- Create responses carry initial_message_status when the initial
  message could not be delivered (queue_full / refused_closed) instead
  of reading as success; staged attachments survive for the retry;
  /send surfaces a closed workstream as 404 rather than queue_full.

Docs/spec: OpenAPI artifacts regenerated; api-reference documents the
new create-response field; TS SDK type extended.

Tests: ~30 new pins (cancel races, budget durability across restarts,
owner-checked registry moves, teardown gating, stall alerts,
backpressure surfaces, wait_until final re-check); wide subsystem
sweep green (2353 passed).

Patrick Buckley bbe92faca1 fix(preview): fetch ceiling tracks the widest kind cap, not a flat 10 MB
Review feedback (PR #800): the URL lane hard-capped fetched bodies at
10 MB before kind resolution, making the 32 MiB pdf cap unreachable for
URL targets while path targets honored it. The flat pre-check is gone;
the guarded fetch's max_bytes now tracks max(PREVIEW_SIZE_CAPS.values())
- mirroring the path lane's stat pre-check - and the per-kind caps after
resolution stay authoritative.

Also drops a redundant function-local asyncio import in test_console.py.

Patrick Buckley 29a4bbf876 fix(preview,web): stream guarded fetches under a byte budget; salt preview blob ids
fetch_with_ssrf_guard now streams the response under a max_bytes budget
(default 32 MiB, counted on decoded bytes so gzip cannot expand past it)
instead of buffering blind - an unbounded body previously filled memory
before any caller-side size cap could run. Redirect-hop bodies are no
longer read at all, and the realized response drops stale wire-framing
headers (content-encoding/content-length/transfer-encoding) that no
longer describe the decoded content it carries.

Preview blob ids are salted out of the model-visible attachment
namespace (sha256("preview:" + body)): uploads use bare sha256(body)
and save_attachment freezes kind at first insert, so a byte-identical
preview/upload pair would otherwise share a row - whichever landed
second inherited the other's kind, silently hiding an upload from model
context or materializing preview bytes into a tool turn.

Patrick Buckley 09abc9d199 feat(tools): allow_private_network opt-in for private-address fetch/preview
turnstone's primary audience self-hosts it beside other lab services —
a web_fetch or open_preview aimed at Grafana, Home Assistant, or a dev
node on the local network is the operator using their own network, not
an attack. The hard SSRF refusal made those targets unreachable.

New runtime setting tools.allow_private_network (settings registry,
default off, rendered in console Settings → Tools; hot — read per tool
call, no restart). When enabled, a call NAMING a private address
becomes approvable: the approval prompt tags it "(private network)" so
the operator approves it as what it is, and the human gate stays.

The redirect side-door stays closed either way: a PUBLIC target that
302s into private address space is refused regardless of the opt-in —
that address never appeared on the approval card, so it is never
fetched. Only a chain whose approved origin was itself private skips
hop screening (its redirects are the operator's own network).

Refusals now teach the knob (mirrors the oidc opt-in hint): the error
names tools.allow_private_network and where to enable it. Surfaces
without a ConfigStore (bare CLI, eval) stay strict — there is no admin
surface to have opted in on.

Patrick Buckley 1e2ab91ec2 feat(preview): probe preflight, legacy charsets, remote-assets opt-in, md vendor parity
Four follow-ups to the preview pane:

- Probe-mode preflight: the pane preflights src-loaded kinds with
  GET ?probe=1 (204, real hardening headers, no body) instead of HEAD —
  the console reverse proxy forwards HEAD as a full GET, so the old
  preflight dragged the whole blob across the node→console hop twice.
  Ownership gate + renderable-type check still run on probes.
- Legacy-charset text: table/text/markdown now transcode to UTF-8 at
  store time (declared charset → UTF-8 → cp1252-replace ladder), same
  model the web kind already used. The ladder applies only when the
  text kind was DECLARED (MIME/extension/override); the bare no-hint
  fallback stays strict UTF-8 and NUL bytes still hard-reject, so
  binary rejection is unchanged.
- Remote assets default OFF: previewed pages are now served under
  "sandbox; default-src 'none'; style-src 'unsafe-inline'; img-src
  data:; font-src data:" — they render with inline styling but cannot
  contact their origin site (no viewer IP/traffic disclosure). A
  per-pane "Load remote images & styles" checkbox (web previews only,
  sticky, not persisted) reloads with ?assets=1 for the permissive
  bare-sandbox mode.
- Markdown vendor parity: preview markdown now runs renderer.js's
  postRenderMarkdown (hljs token coloring + lazy mermaid diagrams)
  like the conversation pane, with preview-scoped code-block/KaTeX
  chrome (the conversation theme is .msg.assistant-scoped).

Tests: probe/assets HTTP + policy coverage, charset ladder units +
stored-bytes round-trip, JS static guards for the probe form, the
default-off toggle, and the post-pass; headless-chrome harness grew to
41 assertions (probe-not-HEAD, toggle visibility/default, fenced-code
render). Full suite green.

Patrick Buckley e010124008 feat(preview): rich preview pane + open_preview tool
Tool results only ever rendered as plain text in the transcript. This
adds the model-driven rich-preview lane every comparable surface has,
in turnstone's developer-tool idiom: a preview pane that opens BESIDE
the conversation, keyboard-operable, sandboxed, never replacing the
transcript that spawned it.

Backend
- New built-in open_preview(target, kind?, title?): resolves an http(s)
  URL, a file path, or attachment:<id> to bytes; classifies into
  web/pdf/image/table/text/markdown (magic bytes > MIME hint >
  extension > UTF-8 fallback, legacy-charset pages transcoded); caps
  size per kind; persists content-addressed with kind="preview" —
  refcounted and GC'd with the workstream, skipped by trajectory
  reconstruction so preview bytes can never materialize onto the wire.
  URL targets gate like web_fetch (network egress); paths/attachments
  run unprompted like read_file.
- New core.web.fetch_with_ssrf_guard: manual redirect walk that
  SSRF-screens every hop BEFORE requesting it (follow_redirects=True
  checked nothing between hops); adopted by both open_preview and
  web_fetch. URL userinfo is stripped before the descriptor or the
  stored bytes see it; <base href> is injected doctype-safely so
  relative assets resolve without quirks mode.
- The preview descriptor rides the tool turn's meta side channel with
  ONE shape on every boundary: the live tool_result SSE event, the
  conversations.meta column, and the /history projection. Cancelled
  batches commit an already-announced preview (blob + meta) instead of
  stranding the open pane on a permanent 404.
- New GET {ws}/attachments/{id}/preview (read scope, same ownership
  gate as /content) serves the STORED type with per-MIME hardening:
  bare CSP sandbox for text/html (renderable, scriptless, opaque
  origin), no CSP for application/pdf (Chromium's viewer refuses
  sandboxed contexts), full default-src 'none' otherwise; filenames
  fold to latin-1-safe ASCII. The console /node proxy now forwards
  CSP/nosniff/disposition/cache-control instead of dropping them.
- History loads exclude preview blobs from the bulk content fetch at
  the query (they were read and discarded on every load).

Frontend
- New "preview" pane type registered in the shared shell (server +
  console): openPaneBeside placement, per-kind renderers — fully
  sandboxed iframe for pages, browser PDF viewer, sortable tables
  (CSV/TSV/JSON, ragged-file safe, 5k-row cap), rendered markdown,
  text — plus back/forward history with arrow keys, reload persistence
  via pane meta, and backoff auto-retry (0.9s..7.2s) bridging the gap
  between the live descriptor and the batch fold that commits its blob.
- Tool results carrying a descriptor render a credential-redacted
  preview chip (the reopen + replay affordance); live results auto-open
  the pane only while the originating pane holds focus.

Docs: docs/tools.md + prompts/tools.md. Tests: policy unit tests, tool
prepare/exec (mocked fetch), serving route + proxy header pass-through,
storage exclusion on both backends, cancel-path commit, JS static
guards; a headless-Chrome harness drives the real module graph (32 DOM
assertions).

Patrick Buckley 4350248d8f fix(oidc): carry the opt-in hint on discovered-endpoint rejections
The discovered-endpoint wrapper converted every OAuthSSRFError to a
bare OIDCError, so a private-resolving endpoint or trusted host got the
non-public message without the allow_private_network remediation even
though the same knob fixes it. Hoist the hint into a module constant
and append it in both wrappers.

Also name "unspecified" in the refused-even-with-opt-in message so
0.0.0.0/:: rejections read unambiguously.
2026-07-06 21:52:42 -07:00
Patrick Buckley 9c74673fd4 feat(oidc): allow_private_network opt-in for self-hosted IdPs
The SSRF guard on OIDC endpoint URLs hard-refused any hostname
resolving to a non-public address, which made it impossible to use a
self-hosted IdP (Keycloak, Authentik, Dex) on an internal network —
even though the login-flow issuer is operator-configured, i.e. trusted
input.

Add [oidc] allow_private_network in config.toml (or
TURNSTONE_OIDC_ALLOW_PRIVATE_NETWORK), default off. When set, the
issuer and its discovered endpoints may resolve to private-range,
unique-local, CGNAT, and loopback addresses. Link-local, multicast,
unspecified, and reserved ranges stay refused regardless — cloud
metadata services live on link-local and no legitimate IdP does. The
HTTPS requirement and same-origin endpoint checks are unchanged.

The private-address refusal now raises OAuthSSRFPrivateAddressError,
and the OIDC wrapper appends the remediation hint to the error message
so the failure is self-service. mcp_oauth call sites — where endpoint
URLs come from untrusted remote-server metadata — do not get the knob
and keep the strict public-address rule.

Patrick Buckley 19b1a04f17 fix(redaction): match connection-string schemes case-insensitively
RFC 3986 schemes are case-insensitive, so POSTGRESQL+PSYCOPG2:// or
HTTPS://user:pass@host in tool output leaked the password past the
case-sensitive scheme alternation. Compile with IGNORECASE on both
sides of the FE/backend mirror; the structural userinfo requirement
is unchanged. Uppercase-scheme cases added to both test suites.

Patrick Buckley ed2623ff44 fix(redaction): match SQLAlchemy driver schemes; add FE prefilter bailout
Connection-string redaction (the output_guard pattern and its frontend
mirror) only enumerated bare dialects plus +psycopg, so SQLAlchemy
dialect+driver URLs — postgresql+psycopg2://, postgresql+asyncpg://,
mysql+pymysql:// — leaked the password through every redaction surface.
The scheme now takes an optional +suffix instead of enumerating drivers.

redactCredentials() also gains a single early-exit prefilter scan ahead
of its sixteen replace passes, for plain-log tool output on card render.
The prefilter is documented and pinned as a superset of the pattern
set's required substrings, so a miss is provably a no-op: new smoke
cases assert bare sk-/AKIA/Bearer credentials with no '=', quote or '@'
anywhere in the text still redact, alongside the fast-path no-op and
the driver-scheme URLs on both sides of the mirror.

Patrick Buckley a029849724 fix(models): keep raw exception text out of client-construction 503s
Review: the wrapped ValueError is echoed in 503 bodies, and arbitrary
SDK exception text can embed filesystem paths. Echo the exception type
only; log the full exception with traceback at the raise site.
2026-07-06 21:10:27 -07:00
Patrick Buckley 9c2e809b26 fix(models): surface client-construction failures as factory misconfig
SDK client construction can fail on environment problems the config
never sees (e.g. httpx resolving a certifi CA path deleted by a venv
rebuild). Those escaped as bare exceptions and turned every workstream
open/create into an opaque 500; re-type them as ValueError in
ModelRegistry.get_client so routes answer 503 with the message and the
alias.

Patrick Buckley 51ed336989 fix(storage): survive oversized rows in postgres history search
to_tsvector was computed inline over full row content, so one row
whose tsvector exceeds PostgreSQL's 1MB limit aborted every
search_history scan. Cap the FTS input at 250K chars (worst-case
tsvector expansion stays under the limit; giant rows remain findable
by their head). The ILIKE fallback also never ran on postgres: the
failed statement leaves the autobegun transaction aborted, so roll it
back before falling back.

Patrick Buckley 647939fe4d fix(personas): repr the input in the not-found resolver error
Review feedback on #792: the "not found or disabled" branch
interpolated the raw input unquoted, so the whitespace-only and
trailing-space inputs the forgiving lookup explicitly handles rendered
invisibly in CLI output and logs. Use {name!r} like the other two
resolver errors already do.

Patrick Buckley 457b01737a feat(personas): agent discoverability + forgiving name resolution
Coordinators and interactive agents had no way to enumerate valid
persona names: task_agent / spawn_workstream / spawn_batch described
`persona=` but nothing listed what it accepts, and resolution was an
exact case-sensitive slug match - users reaching for the display name
or a case variant got an unexplained failure.

- Inject the live persona catalog (enabled, interactive-kind; children
  and sub-agents are always interactive) into the `persona` parameter
  description of task_agent / spawn_workstream / spawn_batch, riding
  the same render path as the model-alias injection. Rebuilt from the
  pristine TOOLS base every render, so repeated renders are idempotent
  and archived personas drop out instead of lingering. Entries carry
  name + default marker + <=96-char description; names-only past 25
  personas. spawn_batch's persona property is nested per-child under
  children.items.properties (located via _persona_property, null-safe
  against name-colliding MCP tools). Storage-less sessions keep the
  base text: the render runs at session construction, so it gates on
  is_storage_initialized() rather than get_storage(), which would
  auto-init SQLite as a side effect.

- resolve_persona_for_kind - the ONE shared rule behind the HTTP
  create handler, CLI --persona, the coordinator spawn precheck, and
  task_agent prep - is now forgiving: exact slug, then the lowercased
  input (created names are regex-enforced lowercase slugs), then a
  case-insensitive display-name match accepted only when unique among
  the kind's enabled personas. Duplicates refuse loudly naming the
  candidate slugs; a same-label persona of another kind neither blocks
  nor wins (the label the caller saw came from a kind-filtered
  surface); whitespace-only input never matches blank display names
  (display_name defaults to ""). Every failure now enumerates the
  kind's valid names, so a stale injected list or a typo self-corrects
  on the next attempt.

- The canonical slug is stamped everywhere: task_agent prep rewrites
  its arg from the resolved snapshot, _validate_child_persona returns
  (canonical, error) and both spawn call sites adopt it - approval
  chrome, the wire, and workstream_config never carry a forgiven
  variant.

- Create-persona shelf: label hint under Name explaining agents and
  the CLI launch the persona by this name (case-insensitive) and the
  display name is only a list label. docs/personas.md gains a "How
  agents discover personas" section and drops the stale claim that
  task_agent has no persona parameter.

Tests: resolver unit suite (case/display/ambiguity/cross-kind/
whitespace/disabled/storage-failure) + guards for injection content
and ordering, idempotent re-render, archive drop, the 25-persona
prose cutoff, coordinator-kind exclusion, and canonical stamping
through spawn_workstream / spawn_batch / task_agent.

Patrick Buckley a40ff249ec fix: address review — request-scoped storage in coord tenancy checks
- _coordinator_tenant_check and _coord_attachment_owner resolved storage from
  the global registry (get_workstream_row / for_request without a storage arg),
  which can evaluate the project-tenancy decision against a different or
  auto-initialised backend and fail OPEN on a missing project row. Use
  request.app.state.auth_storage explicitly, matching cluster_ws_detail and
  _resolve_coordinator_or_404; fail closed (404) when it is unset.
- reject_unassignable_scopes now derives its allowed-scope error message from
  ASSIGNABLE_SCOPES so validation and the message can't drift.
2026-07-06 19:16:09 -07:00
Patrick Buckley 36419a9809 fix: scope private-project workstream visibility to members, not admins
Workstreams attached to a private project were visible -- including their
conversation content -- to holders of admin.cluster.inspect / admin.coordinator
(both default builtin-admin permissions), defeating the project's confidentiality
boundary. Enforce that a private project's resources are visible only to people
IN the project (owner, workstream creator, or an explicit member), even for admins.

Surfaces closed:

- WorkstreamProjectVisibility bypass narrowed to service scope only (node->console
  machine plumbing, re-filtered per-user at the console edge). No human principal
  bypasses; admin.cluster.inspect gates the inspect surfaces, not tenancy. This
  flows to /dashboard, session listings, the attachment row-gate, cluster_workstreams,
  cluster_node_detail, and cluster_snapshot/SSE.
- cluster_ws_detail 404-masks a workstream in a private project the caller can't
  see; cluster_ws_live_bulk routes such ids to the denied list (no private-project
  oracle).
- Coordinator operator verbs (history/export/detail/send/approve/set_title/open/
  children/tasks/attachments) now enforce project tenancy: _coordinator_tenant_check
  on coord_endpoint_config, the gate in _resolve_coordinator_or_404 (children/tasks),
  the tenant_check now run in make_open_handler before rehydrate, and a
  project-visibility check in _coord_attachment_owner. admin.coordinator gates the
  surface cluster-wide, but a non-member is 404-masked. The tenant-check mirrors the
  manager-first + coordinator-kind ladder so kind-isolation is preserved.
- service scope is no longer user-assignable: admin_create_token and both
  turnstone-admin CLI mint paths reject it via reject_unassignable_scopes, so an
  admin.users holder cannot self-mint a service token and restore the bypass. Service
  scope is minted only by ServiceTokenManager / the JWT secret.
- The events/global node proxy (service-elevated cross-tenant firehose) is gated on
  admin.cluster.inspect so a plain authenticated user cannot reach it through the
  console proxy.

Updates the OpenAPI description, the row-gate/tenancy-filter docstrings, and adds
tests for every surface (visibility predicate + cluster detail/bulk + coordinator
history/export/children/open/attachments + events/global proxy + scope-mint
rejection); inverts the tests that pinned the old admin-bypass contract.

Patrick Buckley 0c2c534c86 fix(mcp): route pool transport lifecycles through per-entry owner tasks (#788)
* fix(mcp): route static transport lifecycles through per-server owner tasks

A crash-looping MCP server drove the mcp-loop thread to a sustained,
climbing 100%+ CPU spin. Root cause: anyio cancel scopes are
host-task-bound, and the static path entered the SDK's transport /
ClientSession task-group scopes from short-lived connect tasks (every
health tick is a new task since #768). Once such a scope was cancelled
after its host task had finished - by anyio's task_done when a
transport child died with the server, or by ClientSession.__aexit__
during a cross-task teardown - CancelScope._deliver_cancellation could
never make progress (task.cancel() on a done task is a no-op) and
re-armed itself via call_soon every loop iteration, forever: ~900k
callbacks/s per zombie scope, one more per flap cycle (verified against
anyio 4.14.1; no upstream fix exists as of that release).

Fix: each static server's transport + session cms are now entered,
parked, and exited by ONE long-lived owner task
(_static_transport_owner), so scopes always have a live host and always
exit in the task that entered them. Teardown follows a one-cancel close
protocol (signal the close event before the first await, graceful
grace, then at most ONE cancel - never a second, which would abandon a
scope exit mid-flight). Connect timeouts now cancel only the waiting
caller; connect failures are delivered through a readiness future;
unrequested owner death (server died under a live session) evicts the
session immediately via a done-callback instead of waiting for the next
liveness ping. A rate-limited, mcp-loop-scoped gc-walk backstop
(_maybe_disarm_orphaned_scopes) disarms any zombie minted by paths not
yet migrated (the oauth_user pool keeps the old cross-task-close shape;
follow-up).

Also fixed: BaseExceptionGroup (BaseException-derived, as raised by
anyio task groups wrapping a stray CancelledError, e.g. an
accept-then-RST server) escaped `except Exception` in _connect_all and
killed it before the health/sweep loops were created - silently
disabling all autonomous recovery. Handled there and in the
health/sweep/eviction loops and the reconnect/refresh callers.

Verified: a live SIGKILL-flap repro went from 130%+ CPU (climbing, one
armed scope per cycle) to 0.3% flat with zero armed scopes; the RST
repro now leaves both background loops alive (previously both silently
dead). New tests: owner-lifecycle + close-protocol units (incl. an
exactly-one-cancel pin), a _connect_all BaseExceptionGroup regression,
a discriminating disarm-sweep test, and a ~10s live SIGKILL-flap smoke
test (real FastMCP subprocess, skips on environment gaps) asserting
zero armed scopes, exactly one live owner, and a post-recovery tool
call. Full 8470-test suite green; ruff+mypy clean.

* fix(mcp): route pool transport lifecycles through per-entry owner tasks

Completes the owner-task migration started for the static path: the
oauth_user pool path had the same latent anyio cancel-scope exposure
(host-task-bound scopes entered by short-lived connect tasks; a scope
cancelled after its host finished re-delivers cancellation via
call_soon forever - the 100%-CPU zombie), previously covered only by
the disarm backstop.

Each (user, server) pool entry's transport + ClientSession cms are now
entered, parked, and exited by ONE long-lived owner task
(_pool_transport_owner). The caller keeps building client_kwargs (the
per-user bearer and, when an auth-capture carrier is active, the
httpx_client_factory response hook) so 401/WWW-Authenticate capture
semantics are unchanged. Teardown is the shared one-cancel close
protocol (_teardown_pool_entry: signal before first await, graceful
grace, at most ONE cancel), used by the connect stale-guard, idle/LRU
eviction, and shutdown (parallel signal-then-reap). Unrequested owner
death evicts the session but keeps the entry and its discovered
catalog, matching the existing evict-session-keep-entry semantics the
auth_401 retry relies on.

Discovery still runs in the connecting caller while the transport is
hosted by the owner, so a transport collapse mid-discovery (e.g. the
SDK tearing its task group down on an upstream 401) cancels the OWNER,
not the caller - a bare await on the response stream would hang until
the 30s phase timeout. _await_pool_discovery races each discovery
await against owner completion and converts owner death into a prompt
ConnectionError (the owner is never cancelled there; teardown owns its
lifecycle). Carrier-first failure classification preserves auth_401
semantics for captured 401s.

With no cross-task stack closes left, _safe_close_stack and
_safe_teardown_on_connect_failure are deleted (zero callers).

Tests: new tests/test_mcp_pool_owner.py pins the pool close protocol
(graceful event-before-await close, exactly-one-cancel escalation,
owner-death eviction retaining entry+catalog, caller-cancel-mid-connect
cm-exit guarantee, factory-present-iff-capture, and the
owner-death-during-discovery fast-fail). 1010 mcp tests and the full
8471-test suite green, including the historical cross-task-anyio
sentinel test_integration_pool_reuse_401_refresh_and_retry_succeeds;
ruff+mypy clean; zero destroyed-task warnings.

* fix(mcp): harden disarm-sweep loop guard and owner BaseException arm

Review follow-ups on the owner-task migration:

- _maybe_disarm_orphaned_scopes now enforces its mcp-loop requirement
  instead of trusting callers: it returns without walking (and without
  advancing the rate-limit clock) unless the currently running loop IS
  self._loop. A suppressed close can fire before start() or after
  shutdown(), where the walk would be wasted at best and a cross-thread
  reach at worst.

- The transport owner's BaseException arm now re-raises non-Exception,
  non-group escapees (KeyboardInterrupt, SystemExit) after delivering
  them to the readiness future - failure delivery is the arm's job;
  swallowing an interpreter-level exit was not.

* fix(mcp): extend owner-death discovery fast-fail to the static path

The static connect path had the same exposure the pool's discovery race
closed: discovery runs in the connecting caller while the transport is
hosted by the owner task, so a transport collapse mid-discovery cancels
the OWNER and the caller's bare await on the response stream hung until
the caller-side attempt timeout (~45s) instead of failing promptly.

_await_pool_discovery is renamed to _await_owner_discovery (it is now
path-neutral) and wired into _connect_one_locked's four discovery
awaits. The helper also converts a discovery future that completes
CANCELLED without the race's own reap (an SDK-internal cancellation
shape) into the same ConnectionError, instead of leaking a bare
CancelledError the caller would misread as its own cancellation.

The pool transport owner's BaseException arm gains the same refinement
the static owner received in review: interpreter-level exits
(KeyboardInterrupt, SystemExit) re-raise after delivery to the
readiness future instead of being swallowed.

Tests: static owner-death-during-discovery fast-fail (<1s vs the ~45s
hang), and a direct pin on the cancelled-discovery-future conversion.

* fix(mcp): replace owner BaseException arm with targeted catch + finally delivery

The owner's failure arm now catches only (BaseExceptionGroup, Exception);
waiter delivery for everything else moves to a finally that resolves the
readiness future with a clean transport-failure ConnectionError before
the task unwinds. Interpreter exits and BaseException-derived library
control-flow escapes propagate from the owner exactly once, uncaught -
and the waiter can never be left hanging on an unresolved future (the
initial _connect_all connect has no outer bound). For SystemExit /
KeyboardInterrupt asyncio additionally stops the loop right after, so
the delivery is load-bearing for the non-exit BaseException shapes and
free for the exits.

Pinned by a test driving a BaseException-derived escape through the
owner: the waiter resolves promptly with ConnectionError while the
escape propagates unswallowed.

* fix(mcp): mirror targeted-catch + finally delivery in the pool owner

Same shape the static owner received in review: the failure arm catches
only (BaseExceptionGroup, Exception), and waiter delivery for anything
else moves to a finally that resolves the readiness future with a clean
ConnectionError before the task unwinds - interpreter exits and
BaseException-derived library escapes propagate exactly once, uncaught,
and the waiter can never be left hanging.

* test(mcp): narrow the escape test's waiter catch to explicit types

* test(mcp): narrow discovery-race waiter catches to explicit types

* refactor(mcp): make reap/synchronization awaits explicit to analyzers

Full-absorb reaps (cancel-then-drain of a future whose outcome is
deliberately consumed) become `await asyncio.gather(x,
return_exceptions=True)` - one line, self-describing, and in the
owner-died discovery reap it is also a small semantic improvement: a
caller cancellation arriving during the reap now propagates instead of
being masked by the ConnectionError. Bare synchronization awaits and
selective suppress blocks in tests keep their raise-through semantics
via throwaway assignment. Applied uniformly across the owner-task
test files, including sites introduced by the static-path PR.

Patrick Buckley 62f62ae624 fix(mcp): route static transport lifecycles through per-server owner tasks
A crash-looping MCP server drove the mcp-loop thread to a sustained,
climbing 100%+ CPU spin. Root cause: anyio cancel scopes are
host-task-bound, and the static path entered the SDK's transport /
ClientSession task-group scopes from short-lived connect tasks (every
health tick is a new task since #768). Once such a scope was cancelled
after its host task had finished - by anyio's task_done when a
transport child died with the server, or by ClientSession.__aexit__
during a cross-task teardown - CancelScope._deliver_cancellation could
never make progress (task.cancel() on a done task is a no-op) and
re-armed itself via call_soon every loop iteration, forever: ~900k
callbacks/s per zombie scope, one more per flap cycle (verified against
anyio 4.14.1; no upstream fix exists as of that release).

Fix: each static server's transport + session cms are now entered,
parked, and exited by ONE long-lived owner task
(_static_transport_owner), so scopes always have a live host and always
exit in the task that entered them. Teardown follows a one-cancel close
protocol (signal the close event before the first await, graceful
grace, then at most ONE cancel - never a second, which would abandon a
scope exit mid-flight). Connect timeouts now cancel only the waiting
caller; connect failures are delivered through a readiness future;
unrequested owner death (server died under a live session) evicts the
session immediately via a done-callback instead of waiting for the next
liveness ping. A rate-limited, mcp-loop-scoped gc-walk backstop
(_maybe_disarm_orphaned_scopes) disarms any zombie minted by paths not
yet migrated (the oauth_user pool keeps the old cross-task-close shape;
follow-up).

Also fixed: BaseExceptionGroup (BaseException-derived, as raised by
anyio task groups wrapping a stray CancelledError, e.g. an
accept-then-RST server) escaped `except Exception` in _connect_all and
killed it before the health/sweep loops were created - silently
disabling all autonomous recovery. Handled there and in the
health/sweep/eviction loops and the reconnect/refresh callers.

Verified: a live SIGKILL-flap repro went from 130%+ CPU (climbing, one
armed scope per cycle) to 0.3% flat with zero armed scopes; the RST
repro now leaves both background loops alive (previously both silently
dead). New tests: owner-lifecycle + close-protocol units (incl. an
exactly-one-cancel pin), a _connect_all BaseExceptionGroup regression,
a discriminating disarm-sweep test, and a ~10s live SIGKILL-flap smoke
test (real FastMCP subprocess, skips on environment gaps) asserting
zero armed scopes, exactly one live owner, and a post-recovery tool
call. Full 8470-test suite green; ruff+mypy clean.

Patrick Buckley 31a1d5c3ee fix(redact): harden credential redaction and restore JS/backend parity
Address review findings on the client-side credential redactor and mirror
each fix into the backend output guard so both surfaces censor identically:

- Detect and redact single-quoted JSON secrets such as
  {'Authorization': 'Bearer ...'} (Python dict reprs / JS object literals),
  which the double-quote-only pattern silently bypassed on both sides.
- Cover mongodb+srv://, rediss:// and amqps:// connection strings.
- Match the Bearer auth scheme case-insensitively (RFC 7235).
- Redact prefixed key/token assignments (api_key=, secret_key=,
  access_token=) as a whole rather than chewing the tail into a garbled
  "api_[REDACTED:api_key]", while still covering bare key=/token=. A word
  boundary was rejected because it would drop coverage for <prefix>_key=.
- Remove the redundant |Authorization alternative (covered by /i) and swap
  the manual value-slicing helper for a capture-group substitution.

The backend edits touch both detection sites and both redaction pipelines,
so single-quoted secrets are flagged (and therefore sanitized), not merely
rewritten. Adds JS runtime-smoke and backend unit coverage for every case.
2026-07-05 13:26:32 -07:00
Patrick Buckley 93a7486cc2 Add client-side credential redaction for tool call cards
New shared ES6+ module (redact_credentials.js) provides comprehensive
visual credential censorship matching the backend output guard patterns:

  - PEM private key blocks, connection strings, Bearer tokens
  - OpenAI / GitHub / AWS / Google API key formats
  - Query-string and JSON-style credential values
  - JSON secret keys (api_key, password, token, authorization, etc.)
  - ENV secret lines (SECRET_KEY=, DATABASE_URL=, etc.)

Integrated into both frontend surfaces:
  - interactive.js: replaces legacy minimal _redactApiKeys function
  - conversation.js::buildConvResult (shared substrate, used by coordinator)
  - coordinator.js::renderToolOutput fallback paths

Backend parity: added 'authorization' to the JSON secret regex in
output_guard.py so the output guard flags and redacts Authorization
headers in JSON tool output.

Tests: ported the runtime smoke test from the removed _redactApiKeys
to import the new module directly; added redact_credentials.js to the
var-free and const-reassign guard bundles.

Patrick Buckley 56624f9597 fix(core): scrub credentials and control chars from tool-args log preview
`tool_args_preview` feeds `stream.tool_args_malformed` (WARNING) and
`wire.tool_args_legalized` (DEBUG), and tool arguments are model/user
controlled — they can carry secrets (a token in a bash command, a password in a
connection string) or raw CR/LF that break log lines. Route the preview through
`output_guard.redact_credentials` over the full value first (before the 120-char
cap, so a secret straddling the cut isn't half-shown past the pattern's reach),
then collapse every control char to a space, mirroring `audit._scrub_string`.

Addresses the PR review comments.
2026-07-05 11:59:52 -07:00
Patrick Buckley 16a68ae6d6 fix(core): legalize malformed tool-call arguments before the wire
A tool call whose `arguments` is not a JSON-object string (an unterminated
string from a non-`length` truncation, or an empty `""` from a no-arg call)
was committed verbatim and replayed on every subsequent send. Strict renderers
that re-parse arguments at render time (vLLM's `deepseek_v4`
`_postprocess_messages` runs `json.loads` on them) reject the whole request
with HTTP 400, wedging the conversation. The only prior guard dropped partial
tool calls on `finish_reason == "length"`; a `stop`/`tool_calls` finish reason
carrying invalid JSON slipped through, and its synthetic "retry" result kept it
from being an orphan, so the orphan-repair pass never touched it.

Add `sanitize_tool_call_arguments`, a wire-neutral legalize pass in lowering
(fold, legalize, repair), normalizing any non-JSON-object `arguments` to `{}`
on the transient wire copy only. The canonical trajectory keeps the raw model
output, so a wedged session self-recovers on its next send. A
`wire_valid_arguments` predicate is shared with a non-destructive
`stream.tool_args_malformed` warning at the stream accumulator, which surfaces
the model-quality problem at production time.

Convert `lowering.py` to structlog so the new pass emits structured events.

Patrick Buckley 2d4cb6fea9 fix(ui): make pane hotkeys work off macOS and match across surfaces
The pane/workstream accelerators only worked on macOS. They were bound to
Ctrl, which on Windows/Linux IS the browser's own accelerator: Ctrl+T,
Ctrl+W and Ctrl+1-9 were swallowed by the browser (new tab / close tab /
switch tab) and never reached the page. macOS browsers own Cmd instead, so
Ctrl was free there and everything appeared to work.

On top of that the shortcuts were declared in three places that had drifted
apart — the "?" overlay, each app.js keydown handler, and the tab-menu
badges in shell.js. The console fell to convTabMenu's node-proxy fallback
lane, which dropped every shortcut badge (and Fork), so its tab menu showed
no accelerators and Ctrl+W there just closed the browser tab.

Choose the modifier per platform (Ctrl on macOS, Alt on Windows/Linux) and
make shell.js the single source of truth for the per-pane accelerators: a
stable accel registry drives both the platform-aware badge and one shared
keydown handler that invokes the ACTIVE pane's own menu item, so a badge
can't advertise a chord the handler ignores and each surface contributes
only what it supports (the console omits Fork; it has no fork surface yet).

Each surface's app.js keeps only its global accels (new / switch /
dashboard); the console regains switch + dashboard to match. Mod+W now
uniformly means Close pane (drop the tab, session keeps running), matching
its badge and the universal Ctrl+W convention — previously the standalone's
Ctrl+W stopped the session. The previously-dead "Refresh title / Ctrl+Shift+R"
is wired, and Ctrl+T / Ctrl+D yield to text editing while a field is focused
(macOS transpose / delete-forward).

Patrick Buckley 3615f98c19 Fix send button stuck disabled by pruning orphaned approval cycles (#775)
* Fix send button stuck disabled by pruning orphaned approval cycles

When a DOM wipe (clear_ui / replay_truncated / replaceChildren)
detaches approval card elements while an approve_request event is
processed between the wipe and refetch-restore, the matching
approval_resolved may never arrive. The orphaned cycle entry in
approvalCycles keeps pendingApproval=true and the send button
disabled forever.

The fix adds a pruning pass at the top of _syncApprovalState():
cycles whose blockEls are all .isConnected === false are deleted
from the Map. This runs on every register/resolve/rebuild so
orphans are cleaned up promptly.

Also fixes an ordering bug in showInlineToolBlock discovered
during review: the block element was appended to the DOM after
_registerApprovalCycle, so the new isConnected prune would kill
the just-registered cycle before it took effect.

* Fix comment inaccuracy in showInlineToolBlock append-before-register guard

The comment said 'blockEls.every(el => el.isConnected)' but the
actual prune check is '!blockEls.some(el => el.isConnected)' -
no block elements are connected, not every element.

Patrick Buckley 6f8efaa44e test(golden): freeze the anthropic-compatible reasoning-effort wire
The wire-payload golden matrix had no anthropic-compatible coverage —
both AnthropicProvider rows are the native lane (compat=False), so the
distinct compat wire shape (reasoning control in
extra_body.chat_template_kwargs, never the native thinking param) was
unfrozen. Add the compat lane across all eight representative fixtures
with a manual-mode capability (the lane has no static table, so caps
ride in as a model definition would supply them) and reasoning_effort=
high: every golden now pins {enable_thinking: true, reasoning_effort:
high} in chat_template_kwargs, asserts the native thinking param is
absent, and preserves temperature (no forced 1.0). _capture gains an
optional caps override to support the no-static-table lane.

Patrick Buckley 530958e06b fix(providers): the session effort level always reaches the local-lane wire
Local lanes dropped the knob's graded value unless the operator declared
reasoning_effort_values (and, on the template channel, an effort key) —
picking Max sent a bare thinking toggle and the effort select
degenerated into seven positions that all meant 'on'. The user's
setting now always rides:

- openai-compatible: the flat reasoning_effort param carries the knob
  verbatim (effort_passthrough on the lane default); declared values
  still snap ordinally, and a declared effort_param still claims the
  template channel and suppresses the flat param.
- anthropic-compatible: the graded value rides chat_template_kwargs
  alongside the toggle whenever reasoning control is engaged — under
  the operator's effort_param, else the conventional fallback key
  (reasoning_effort); templates that don't reference the kwarg ignore
  it. thinking_mode=none still injects nothing.
- Commercial lanes untouched: empty declared values still mean 'no
  effort control' (o1-mini) and the ordinal snap is unchanged.

Golden writer now pins ensure_ascii=False: the baselines' literal em
dashes came from a hand edit (03f82521) the default-escaping writer
could never reproduce — regens no longer churn unrelated lines.
2026-07-05 01:59:38 -07:00
Patrick Buckley e136237b63 fix(providers): openai-compatible never consults the commercial table
Local-lane model ids are operator-chosen strings (vLLM
--served-model-name), so a prefix collision with a cloud model id
inherited that model's sampling and effort contract: a box named
o3-distill silently lost temperature support, and one named
gpt-5.5-my-finetune was sent gpt-5.5's snapped reasoning_effort values
it never declared. Both surfaces of the lane now return plain defaults
(OPENAI_COMPAT_DEFAULT in _openai_common): the chat class directly, and
the responses pin via a compat-mode OpenAIResponsesProvider mirroring
AnthropicProvider(compat=True). Everything beyond the defaults is
declared by the operator on the model definition, matching the
anthropic-compatible lane and lookup_model_capabilities' documented
'no static table for local models' contract. The commercial openai
lane (Responses-only) is untouched.

Pre-split tests that reached commercial rows through the chat-class
OpenAIProvider alias now source them from lookup_openai_capabilities;
their subject (registry rows + shared gating helpers) is unchanged.

Patrick Buckley 41e9907803 fix(console): available-models rows always carry effort_ladder
The except path for a malformed capabilities column appended the row

block overwrite it — the response schema is stable per row.

Patrick Buckley 7f0e0406b3 test(approvals): concurrency matrix + suite migration to the cycle model
New regression matrix for the release blockers: cross-approval
independence, lost-wakeup at gate entry, FIFO selector-less
resolution, resolve-all sweep, double-resolution no-op, cards/legacy
view tracking, and the generation-exactness set — stale delivery
rejection, Smart-Approvals origin check, purge keep_origin, the
purge-to-register window eviction, late cross-generation "superseded"
stamping, concurrent smart+human gates, and the pre-delivered-verdict
fast path. Plus sub-agent judge wiring (agent_gate off the main
slot, close() firing all generations) and endpoint tests for cycle
pinning and the Approve+Always race guard.

Gate threads run under one shared mock-patch harness — mock.patch
start/stop of the same target from concurrent threads corrupts the
patcher's restore stack — with a sweep-until-dead teardown so the
conftest leak guard can't trip. Existing suites migrate off the
singleton fields to cycle assertions and the
pending_approval_details wire shape.

Patrick Buckley 3607517814 fix(providers): registry effort truth — o-series/gpt-5.5/codex-max/sonnet-5; forward declared none
Capability-registry corrections verified against the official OpenAI
reasoning guide, the Azure reasoning-models matrix (2026-06 revision),
and the Anthropic models-overview/effort/migration pages (2026-07):

OpenAI (vocabulary confirmed none/minimal/low/medium/high/xhigh — no
"max" level exists; knob max rides the xhigh ceiling via the ordinal
snap):
- o1/o3/o3-mini/o3-pro/o4-mini declare low/medium/high (every o-series
  model except o1-mini) — without declared values the session knob was
  silently dropped for these models. o1-mini stays effort-free.
- gpt-5.5 default corrected none -> medium (5.5 reasons by default,
  unlike 5.1-5.4).
- gpt-5.1-codex-max gets an explicit row: it prefix-matched the
  gpt-5.1 row (no xhigh), capping the knob's xhigh at high on the one
  model xhigh was introduced for.

Anthropic (effort-page matrix):
- claude-sonnet-5 row added — it previously fell through to
  _ANTHROPIC_DEFAULT (manual budgets, 200k ctx, no effort), all wrong:
  adaptive-by-default thinking (manual budgets are a 400), sampling
  params rejected, 1M ctx / 128k out, effort low..max incl. xhigh.
- claude-sonnet-4-6 gains its documented "max" effort level (knob
  xhigh now rides max, not high) and the stale 64k max_output becomes
  the documented 128k.
- fable-5 / opus-4-8 / opus-4-7 / opus-4-6 / opus-4-5 rows verified
  correct as declared.

Knob semantics completed: resolve_reasoning_effort now forwards the
knob's "none" position verbatim when the model DECLARES an explicit
none level (gpt-5.1+, grok-4.3) — omitting the param there leaves a
reasoning-on server default (gpt-5.5: medium) in charge of a knob
that promises off. Models without a declared none still omit, and
none is never a snap target. Parity harness swaps its synthetic
openai shape for the real gpt-5.5 registry row.
2026-07-04 20:54:20 -07:00
Patrick Buckley a0e04a8588 fix(providers): effort snapping is ordinal — round up, cap at the ceiling
The knob domain grew xhigh/max after the snapping fallbacks were
written, which silently inverted their semantics: off-list meant
"unrecognized string" then, but now usually means "above the model's
ceiling", where falling back to the default tier is directionally
wrong (grok-4.3 at knob max got low; values low/medium/high at knob
xhigh got medium; Anthropic manual mode gave xhigh/max a 4096 budget
while high got 16384).

One rule everywhere now, via snap_reasoning_effort in _protocol:
exact match wins; otherwise the smallest declared level ranking at or
above the knob; above the ceiling, the ceiling. "none" is never a
snap target, and default_reasoning_effort only catches values the
ordinal snap cannot rank.

- resolve_reasoning_effort (flat chat / responses / validated
  effort_param lanes) snaps ordinally: xhigh over (low, medium, high)
  now sends high; xhigh over DeepSeek-style (high, max) sends max —
  matching DeepSeek's official xhigh-to-max aliasing, so a declared
  values list now reproduces that contract instead of defeating it.
- _map_reasoning_to_effort (native output_config) rounds up too:
  knob xhigh on Opus 4.6 (low, medium, high, max) rides max instead
  of silently dropping output_config.
- EFFORT_BUDGET_MAP is monotone across the whole knob domain:
  minimal/low 1024 (API floor), medium 4096, high 16384, xhigh 32768,
  max 65536. Unknown strings still fall to the 4096 default.

Google defaults are unaffected (ceiling and default coincide at
high); wire goldens unchanged. Parity harness caught the budget
clamp interacting with its own max_tokens during development —
capture budget raised above the largest manual budget.

Patrick Buckley ffe8214cfe test(providers): ladder-to-wire effort parity harness across all lanes
Proves the effort-ladder projection against the real request path
instead of against the mapping helpers it shares with it. For 22
(provider lane x capability shape) points — both Anthropic lanes,
openai-compatible on both API surfaces, openai, google (default and
template-override hybrid), xai (default and inert-override), and the
DeepSeek/qwen template contracts — every knob position is driven
through the actual provider create_streaming against a recording fake
client, and two invariants are asserted per shape:

1. each ladder token decodes to an expected effort wire subset
   (toggle / template effort / flat param / thinking budget /
   output_config) that must equal the captured kwargs exactly;
2. two knob positions carry equal tokens iff they produce identical
   effort-relevant wire payloads — the grouping promise the UI
   annotations lean on.

The RecordingClient SDK-seam stub moves from the wire-payload golden
harness into tests/_wire_capture.py so both suites capture at the same
seam. Verified the harness catches the bug class it was built for:
re-adding xai to _CHAT_LANES fails xai-template-override-inert.
2026-07-04 20:54:20 -07:00
Patrick Buckley 1f63f622c9 fix(providers): xai effort ladder is flat-only; share the suppression rule
Second external audit round on the ladder. Verified and fixed:

- xai was in _CHAT_LANES on the false premise that XAIProvider
  subclasses the chat provider. It subclasses OpenAIResponsesProvider,
  whose surface ignores extra_body entirely, so a thinking_mode /
  effort_param override never changes an xai request — but the ladder
  claimed a template toggle ("on+low") that does not exist on the
  wire. xai now projects through the flat channel only, like openai.
- The flat-param suppression rule (a declared effort_param claims the
  template channel) was encoded independently in
  apply_temperature_and_effort and the ladder. Extracted into
  flat_effort_suppressed() in _protocol so the request path and the
  projection cannot drift.
- admin_effort_ladder logs the swallowed resolver exception before
  returning 400 (a genuine bug would otherwise hide as a silent 400).
- list_available_models reads server_compat with .get() instead of
  destructively popping it out of the parsed capabilities dict.
- models_changed SSE now re-annotates the skill launch-config effort
  select after invalidating the models cache instead of leaving a
  stale ladder until the next keystroke.
- Capabilities JSON textarea placeholder hints the two effort fields
  that have no structured control (reasoning_effort_values,
  default_reasoning_effort).

Patrick Buckley f4701bf0f9 test(golden): re-baseline Google wire payloads for the effort knob
The Gemini effort fix (ee9e9c1f) adds a flat reasoning_effort to every
Google chat-completions request at the session default knob — the
golden fixtures now carry it. Only the eight google__* goldens change
(one added key each); other providers' goldens are untouched — the
UPDATE_WIRE_GOLDENS pass also wanted to rewrite twelve passing goldens
with escape-format-only churn (raw em-dash vs \u2014), reverted to
keep the diff semantic.
2026-07-04 20:54:20 -07:00
Patrick Buckley 06cc184227 fix(console): address verified external-audit findings on the effort ladder
The one that mattered: /v1/api/models passed the capabilities column —
a JSON STRING (sa.Text) — straight into effort_ladder_for_model, whose
field filter calls .items() on it; the per-row guard swallowed the
AttributeError, so effort_ladder was silently absent from every row and
the sklc annotation could never fire. The endpoint now parses the JSON
and splits the namespaced server_compat exactly like the model_registry
loader, and a regression test seeds a string-capabilities row.

Projection fidelity: effort_ladder_for_model threads api_surface (the
responses surface ignores extra_body — flat-param-only ladder, matching
create_provider's request-time divergence); google/xai route through
the chat-lane projection they actually inherit (_finalize_extra_body +
flat param); the native-Anthropic branch reflects that output_config
gates on supports_effort alone, independent of thinking_mode; budget
clamping to per-request max_tokens is documented as out of scope.

Hardening and symmetry: admin endpoint 400s (not 500s) on non-dict JSON
bodies and gained HTTP tests; the admin edit-load strips effort_param
from the raw JSON only for the lanes whose save path re-adds it, so
non-compat rows can't silently lose a stored key; the empty-model early
return bumps the ladder sequence so stale in-flight responses can't
re-annotate; alias labels only reference positions the target select
actually offers (the skill shelf omits none/minimal); the sklc models
cache no longer pins a rejected promise and is invalidated on the
models_changed event; debounces unified at 500ms;
merge_reasoning_template_kwargs now always returns a fresh dict for
non-empty input; the shared budget constants are public.

Patrick Buckley 59a527f2f2 feat(console): surface each model's effective effort ladder
Seven knob positions render as seven behaviors in the UI, but the real
ladder depends on the lane and the model: qwen3.6 has two (off/on),
DeepSeek-V4 three, Claude 4.6 five. Operators had no way to see which
positions alias — the confusion class behind silently-equal effort
levels.

providers/effort_ladder.py projects the knob domain through the same
mapping functions the providers use at request time (resolve_reasoning_
effort, reasoning_template_kwargs, the manual budget map — hoisted to a
shared constant so the projection can't drift), yielding
{value, effective} rows where equal tokens promise identical requests.
/v1/api/models rows now carry the ladder (guarded per row), and
POST /v1/api/admin/models/effort-ladder computes it for the admin
modal's unsaved edits.

The admin per-model effort select and the skill launch-config effort
select annotate aliased positions ("Max (= high)", "None (model
default)") with a sends-tooltip; annotations refresh as thinking-mode /
effort-param / capabilities fields change. The ladder describes what
Turnstone sends — server-side templates may alias further (DeepSeek-V4
folds low/medium into its default high tier).

Patrick Buckley d7941c88be fix(providers): thread the session effort knob to Gemini
_GOOGLE_DEFAULT declared no reasoning_effort_values, so
resolve_reasoning_effort returned None and the session effort knob was
silently dropped for every Gemini model — the same bug class this
branch fixed on the local lanes. Gemini's OpenAI-compat surface
documents a flat reasoning_effort (2.5: thinking_budget mapping; 3.x:
thinking_level), so declaring values lights up the inherited
chat-completions path.

Values are the safe cross-model set (minimal/low/medium/high): "none"
is excluded because 2.5 Pro and the 3.x family reject disabling
thinking — and the resolver never forwards the knob's none anyway (the
param is omitted, server default applies). Off-list xhigh/max snap to
the declared default high. Encoded from the official compatibility
docs per the static-caps pattern; not live-verified.

Patrick Buckley 2cf23b6fe2 fix(providers): address high-effort review of the reasoning-knob branch
Verified findings applied:
- adaptive thinking_mode never knob-disables: the shared mapping now
  sends the toggle unconditionally true for adaptive (the native
  adaptive branch ignores the knob's none), while manual keeps the
  knob-driven contract. Restores the invariant the deleted chat-lane
  code upheld.
- a set effort_param suppresses the flat top-level reasoning_effort on
  the chat lane: the template channel replaces it — double-sending
  could 400 on schema-strict servers and disagree with operator pins.
- admin edit-save no longer drops a stored thinking_param when the
  thinking-mode dropdown is empty: the raw-JSON strip now only fires
  when a mode value actually round-trips through the dropdown.
- effort_param persistence gated on the local-server lanes so a value
  lingering across a provider switch never lands on commercial rows.
- three stale _compat_extra_params references renamed to
  merge_reasoning_template_kwargs.

Documented dispositions (no code change): the knob-none-disables flip
on upgrade is intentional and now carries an upgrade note; gateways
fronting real Claude belong on provider=anthropic with a custom
base_url (the compat lane is vLLM-schema-only); nonstandard
thinking_mode strings staying inert is the intended allowlist
contract. The real anthropic provider is unaffected throughout —
official Claude models keep native thinking/output_config.

Patrick Buckley 68b22adfa3 feat(providers): share the effort-knob→chat_template_kwargs mapping with the openai-compatible lane
Hoist the compat-lane injection into _protocol.merge_reasoning_template_kwargs
(next to ModelCapabilities — one implementation for both local-server lanes)
and retire OpenAIChatCompletionsProvider._apply_thinking_mode in its favor:
_finalize_extra_body now receives the session effort knob, so thinking_mode
manual/adaptive maps knob "none" to an explicit thinking_param false
(previously the toggle was unconditionally true) and caps.effort_param
carries the graded effort key on chat completions too. Operator
server_compat pins still win; the Responses surface is untouched (native
reasoning handles effort itself).

The admin Models form grows an "Effort param" field that round-trips like
thinking_param: lifted out of the raw capabilities JSON on edit-load,
re-added on save, cleared by emptying the field.

Verified live against qwen3.6-27b /v1/chat/completions: knob medium streams
reasoning_content, knob none suppresses it.
2026-07-04 20:54:20 -07:00
Patrick Buckley 9289693730 fix(providers): drive reasoning via chat_template_kwargs on the anthropic-compatible lane
The compat lane sent no reasoning control at all: vLLM's /v1/messages
has no thinking request field, thinking_mode stayed "none", and the
session effort knob was silently dropped. The reasoning levers live in
the chat template, so fold them into extra_body chat_template_kwargs
(_compat_extra_params): thinking_mode manual/adaptive maps the knob
onto caps.thinking_param (effort "none" = off, mirroring the native
manual-mode contract), and caps.effort_param (new ModelCapabilities
field) carries a graded effort value for gpt-oss-style templates,
validated against reasoning_effort_values when declared. Operator
server_compat entries win on key collision; native thinking params,
temperature forcing, and output_config never fire on compat.

resolve_reasoning_effort moves from _openai_common to _protocol next to
ModelCapabilities — importing it into _anthropic would otherwise cross
provider families.

The admin Models form now shows and round-trips the thinking-mode
dropdown for this lane; the #661 hide was premised on thinking_mode
being inert here, which this change inverts.

Verified live against qwen3.6-27b on vLLM /v1/messages: knob medium
streams a thinking block, knob none suppresses it, an operator pin
beats the knob.

Patrick Buckley 217d3a3a9b feat(mcp): autonomous reconnect + liveness for static MCP servers (#768)
* feat(mcp): autonomous reconnect + liveness for static MCP servers

Static (non-oauth_user) MCP servers had no autonomous reconnect. Every reconnect
path was lazy — a tool dispatch (_cb_auto_reconnect), an operator refresh, or a
config edit — and the MCP SDK's own reconnect is a bounded 2-attempt burst on the
streamable-http GET stream only (verified: mcp 1.28.1), with no backoff and
nothing for the other transports. So a static server that went down and came back
while nobody was dispatching to it stayed disconnected until a dispatch or a
manual reconnect. Worse, a session whose transport dies while idle survives as a
non-None ClientSession with closed streams — nothing evicts it, so even a later
dispatch may not notice until it fails.

Add a static-server health loop on the mcp-loop (started in _connect_all; config
``static_health_check_seconds`` default 30, <= 0 disables):

- Reconnect: a disconnected server (session is None) is reconnected on a capped,
  jittered, FOREVER backoff (full jitter, base 1s, cap 60s, no attempt limit) —
  a server that returns after a long outage reconnects within ~a minute, and a
  permanently-misconfigured one costs at most one attempt per cap. The health
  loop owns this clock; the circuit breaker stays the DISPATCH fail-fast gate (a
  tool call to a down server errors immediately rather than blocking on the
  retry), and the loop keeps breaker state in sync so an open breaker closes on
  reconnect.
- Liveness: a connected server is pinged (send_ping) each cadence; a dead-but-
  idle one — which nothing else would notice — is evicted so the next tick
  reconnects it. This is the core of the "never reconnects" failure.

Serialize _connect_one per server behind a per-name lock (split into a thin
wrapper + _connect_one_locked): the health loop, a dispatch's _cb_auto_reconnect,
and an operator refresh could otherwise interleave teardown/rebuild on the shared
StaticServerState and corrupt it — a latent pre-existing race this also closes.
The body is unchanged (only relocated), so the delicate anyio / wait_for connect
logic is untouched.

Out of scope (follow-up): silent GET-stream / notification death — the SDK stops
the notification stream after 2 attempts while the request path stays alive, so
send_ping is blind to it; the fix is bounded session recycling, which needs a
static in-flight guard first (only PoolEntryState tracks in_flight today).

Tests: backoff bounds (capped / jittered / forever, no overflow), reconnect
success resets backoff + closes breaker, reconnect failure retries forever,
in-flight skip, per-name serialization (no overlap), ping keeps healthy / evicts
dead / evicts on timeout, tick skips oauth_user, connect_all start + disable
gating, clean cancel.

* fix(mcp): harden static-server health loop (review findings)

A max-effort review found 13 concurrency/correctness defects, all from the loop
mutating shared StaticServerState without the interlocks the pool path carries.
Fix all 13:

- In-flight interlock: add StaticServerState.in_flight (parity with
  PoolEntryState); _static_session_op increments/decrements around the static
  call_tool/read_resource/get_prompt session ops; the ping skips and never
  evicts a busy server, so a long tool call can't be torn down mid-flight.
- Dead-transport gating: the ping evicts + trips the breaker only on
  _is_dead_transport(exc); an McpError, httpx.PoolTimeout, or plain ping timeout
  is "slow, not dead" and only reschedules (matching the dispatch path).
- Session-identity: only evict the exact session that was pinged.
- asyncio.timeout (invariant-18) not wait_for for the ping; 5s->30s; the
  timeout-scoped cancel is distinguished from an external shutdown cancel
  (which still propagates) via .expired().
- Bounded reconnect: wrap _connect_one in asyncio.timeout so a server that
  handshakes then stalls list_tools can't wedge the loop or hold the per-name
  lock forever (connect internals untouched).
- Concurrent tick under asyncio.gather with a freshly-read clock for the sleep.
- Cross-path coordination: reconnect_sync/remove_server_sync take the per-name
  lock across teardown+rebuild (calling _connect_one_locked directly);
  _cb_auto_reconnect reuses a health-established session instead of racing a
  redundant reconnect and no longer trips the breaker on lock contention.
- Backoff hygiene on recovery; skip '__' names; on health reconnect clear only
  the open-circuit deadline (not the failure count) so a connect-ok/calls-fail
  server still escalates to a trip.

Adds 14 tests and adjusts those that assumed the old behavior; suite 195->209.

* fix(mcp): unify static-server reconnect coordination (round-3 review)

A third review round + live testing found 8 issues on the health loop, five
sharing one root: reconnect logic was fragmented across five drivers, each
handling the lock / session-reuse / in_flight / config-recheck / breaker / clock
differently and incompletely. Introduce one primitive and route every
lazy/autonomous driver through it.

_ensure_static_connected(name, cfg) — the single lazy (re)connect path, all under
the per-name lock: config re-check (+ lock-identity re-check, closing the
remove->re-add race) so a removed server is never resurrected; reuse-if-live so a
queued/concurrent driver never tears down and rebuilds a live session (the
observed reconnect storm); in_flight guard so a reconnect can't tear down a
session with a call still in flight on the evicted stack; bounded connect; and the
circuit breaker owned in one place (clear the open-circuit deadline on success per
finding-13, record one failure on real connect failure). Returns the session on
success/reuse, None on a deliberate skip, raises on real failure. Routed through
it: the health loop, a dispatch's _cb_auto_reconnect, and _refresh_all; operator
reconnect_sync stays a deliberate force-rebuild.

Also: fresh-clock deadlines (the stale tick-start clock was landing deadlines in
the past and collapsing the backoff into an every-tick retry storm); loop-death
fix (the tick no longer re-raises a CancelledError found in the gather results —
per-server fallout, not shutdown; the loop returns only when Task.cancelling()
marks a genuine shutdown); dispatch breaker records no failure on a sync-boundary
reconnect timeout (lock contention is not a server failure; real outcomes recorded
once, inside the primitive). Cleanups: extract _teardown_static_session (was
copy-pasted 3x); share _capped_exponential between the breaker cooldown and the
reconnect backoff. Adds 17 tests; test_mcp_client 204->226.

* fix(mcp): coherent timeout hierarchy + round-4 review fixes

A fourth review round on the unified reconnect coordination found 5 correctness
regressions + 1 cleanup, five sharing one root: the inner reconnect attempt bound
(45s) was LONGER than every caller wait (dispatch 30s, remove 15s, reconnect 30s),
so a caller cancelling mid-attempt delivered a bare CancelledError that slipped
past the primitive's `except Exception`.

- Coherent timeout hierarchy: add _STATIC_RECONNECT_CALLER_TIMEOUT_S (> the inner
  attempt bound) for the dispatch + operator waits, so the inner asyncio.timeout
  always fires first — a clean TimeoutError the primitive converts, cleans up, and
  records on the breaker — instead of a caller cancelling a live attempt. Fixes
  [0] (half-discovered session left installed, served with a stale catalog) and
  [1] (breaker never trips via dispatch).
- Primitive cancel-safe (belt-and-suspenders): its handler is now
  `except BaseException`, so even a bare CancelledError drops the partial session
  and records the failed attempt before re-raising.
- Operator waits: reconnect_sync / remove_server_sync default timeouts raised above
  the reconnect bound; remove_server_sync now CANCELS the pending _remove on
  timeout (so it can't later pop a re-added entry and corrupt state) and reports
  failure instead of a false 'removed' ([2], [4]).
- in_flight defer is gated on defer_if_busy: autonomous callers (health loop,
  _refresh_all) defer, but a DISPATCH reconnects rather than hard-fail a reachable
  server with an in-flight sibling ([3]).
- Cleanup: extract _schedule_next_ping (was a copy-pasted triplet in 3 branches) [5].

Adds 6 tests; the lock-contention test now shadows the caller-timeout constant so
it runs in ~1s instead of the full wait.

* fix(mcp): address PR review feedback on static reconnect

- _ensure_static_connected: skip breaker record on CancelledError
  (cancel proves nothing about the server; aligns docstring with impl)
- reconnect_sync: add asyncio.timeout wrapper so discovery-phase
  stalls get a clean TimeoutError inside the lock
- reconnect_sync: change except Exception to except BaseException
  so CancelledError from future.cancel() triggers catalog cleanup
- reconnect_sync: null state.session on failure so a tool-less
  session isn't mistaken for a live one
- _static_reconnect_one: use fresh monotonic clock for backoff
  gate instead of stale tick-start snapshot; remove dead now param
- _static_health_tick: correct docstring (0.5s clamp prevents
  busy-spin, not 'no sleep through short backoff')
- Test: new test for reconnect_sync timeout + catalog cleanup
- Test: update cancelled-attempt test for new CancelledError semantics
- Test: narrow except BaseException to except Exception + type hints
- Test: fix typo 'Understone' -> 'Turnstone'
- Test: remove unused stale_now variable; update mock signatures

Patrick Buckley acc262c405 feat(mcp): proactively keep consented OAuth (OBO) tokens fresh for unattended work
Per-user OAuth (auth_type=oauth_user) token refresh is entirely lazy: a token
is refreshed only when a tool is dispatched or a session binds the acting user,
and a dead refresh token is discovered only when a dispatch fails. That assumes
a human is driving the session, which breaks for autonomous / scheduled work
acting on behalf of an absent user — the token may be expired (latency), in a
transient-failure cooldown (unavailable), or the grant may be dead with nobody
present to re-consent. The only periodic MCP-loop task, idle eviction, actively
tears OBO connections down; nothing keeps tokens warm.

Add a background token-freshness sweep that keeps every consented oauth_user
grant hot WITHOUT keeping connections warm and WITHOUT mutating consent state on
a timer.

Sweep (_user_token_sweep_loop, default 240s):
- Enumerates consented (user, server) grants from the token store and runs the
  canonical refresh path for each. Strictly oauth_user-scoped: gates on
  _oauth_user_server_names and drives off mcp_user_tokens rows, so a static /
  no-auth server — which has neither — is structurally invisible (no DB scan, no
  authorization-server round-trip, no MCP-server call). Never connects to the
  MCP server; connections stay lazy.
- Observe-only: passes revoke_on_failure=False (new parameter on
  get_user_access_token_classified) so a timer NEVER deletes a token, emits
  token_revoked, or mutates the shared ambiguous-streak / cooldown. A dead grant
  is only surfaced (proactive dashboard pending-consent badge); the
  authoritative revoke stays on the lazy-dispatch path where a real user action
  justifies it. Because the row survives, a spurious server-wide invalid_grant
  (an AS maintenance window) self-heals — the badge is dropped on the tick the
  grant works again.
- Keepalive: force-refreshes a grant whose refresh token has sat un-exercised
  past user_token_refresh_keepalive_seconds (default 1800s) even while the
  access token is still fresh, so a provider that ages out idle refresh tokens
  can't expire one between a user's real sessions.
- Surfaces dead grants once per transition, pinning the pair only after a
  durable badge write so a failed persist retries rather than being lost. First
  sweep runs after a short startup grace so a restart surfaces a downed grant
  within seconds, not a full cadence later.

Cadence <= 0 disables the sweep; a positive value is floored (30s) so a
misconfigured tiny cadence can't turn the loop into a busy-loop. Reuses the
per-key refresh lock, so a keepalive force cannot double-refresh against a
concurrent dispatch.

Storage: add list_mcp_user_token_reconcile_targets() returning
(user_id, server_name, COALESCE(last_refreshed, created)) — expiry-unfiltered,
no ciphertext projected — on the protocol, sqlite, and postgres backends.

Tests: the sweep's no-auth invisibility (zero DB / AS calls with no oauth_user
server), observe-only non-destruction (token kept and shared streak untouched on
a background permanent / ambiguous failure), keepalive gating, badge
persist-then-pin retry, self-heal on recovery, cadence clamp / disable, and the
storage enumerator.

Patrick Buckley 62034378c6 fix(skills): address Copilot review — task_agent doc refs + gate fail-closed on missing storage
- task_agent.json referenced a non-existent `skill(action='search', query=...)`
  in two spots. The discovery tool is `skills` and the action is `find`
  (`search` is an activation value, not an action), so the guidance would
  mislead the model. Corrected both to `skills(action='find', query='...')`,
  matching the tool's own error strings.
- _high_risk_skill_denied returned "" (allow) when get_storage() is None — an
  asymmetry with the fail-closed lookup-exception path added earlier. A risk
  gate that can't verify the tier must DENY, not wave the skill through, so
  storage-unavailable (None) now denies too; both paths share one denial.

Patrick Buckley bcb8c5ab88 fix(skills): harden task_agent / persona / skill activation from whole-PR review
Two independent multi-agent reviews of the branch (high, then max effort) found
authority-confinement and robustness defects the per-step reviews could not
see. This commit addresses every confirmed finding. task_agent turned out to be
the surface that lagged its siblings on nearly every axis.

Risk gate (most severe):
- task_agent(skill=...) never enforced the high/critical-risk PRINCIPAL-load-
  only gate that skills(load) / spawn_workstream / spawn_batch enforce, so a
  model could route around it by delegating activation to a sub-agent. Enforce
  it inline in _prepare_task on the row already fetched (no re-query, no drift
  between get_skill_by_name and get_prompt_template_by_name).
- _high_risk_skill_denied now fails CLOSED on a storage fault: deny, never wave
  the skill through. Denying (not returning "") also keeps spawn_batch's per-row
  partial-success intact under a transient blip.
- (first round) extracted _high_risk_skill_denied onto spawn_workstream /
  spawn_batch, closing the coordinator-side bypass.

Persona confinement (Principle 7 attenuation on the task_agent edge):
- A restrictive persona now attenuates the sub-agent's TOOLS, not just its
  identity text — the tool lever is frozen into the item and filtered before
  _run_agent.
- Honor ALL FOUR persona levers on the sub-agent, not two: a child persona's
  mcp-off and memory-off levers now drop MCP tools (mcp__* + read_resource /
  use_prompt) and the memory tool, matching a main session under the persona.
- Cap the sub-agent by the PARENT session's own persona grant too, so a
  restricted principal cannot escalate authority by spawning.
- Add persona to the task_agent judge/audit func_args projection (policy +
  audit parity with spawn).
- Persona-resolution failures defer to a clean tool error (try/except mirroring
  _validate_child_persona) instead of an opaque "internal error".

Substitution / capability:
- substitute_args=False for capability contexts (defaults, task_agent) so a
  literal $ARGUMENTS / $N in a body is preserved, not blanked; env vars still
  resolve. The literal-$ARGUMENTS scan is deferred behind that guard (skipped on
  every capability render).
- Drop the CLAUDE_SKILL_DIR alias (canonical TURNSTONE_SKILL_DIR only). That
  name also lives in bash, where turnstone-as-a-node-inside-Claude-Code must not
  shadow the host's value; claiming it in the prompt but deferring in bash
  diverged the two surfaces (a review finding). turnstone now claims it in
  neither surface. The CLAUDE_SESSION_ID / CLAUDE_EFFORT prompt aliases stay
  (pure prompt values, no bash-namespace collision).

Skills-as-context:
- DEFAULT (always-on) skills stay in the identity system message — the standing
  baseline, never a mid-session cache-bust; only a NAMED applied skill moves to
  the user-role capability message. This shrinks the pending model-adherence
  eval surface to the named-skill move alone.

Cleanups: consolidate a duplicated rationale comment; correct the now-stale
"task agents are not persona-filtered" note.

PRE-MERGE GATE unchanged: the §7 Q1 model-adherence eval (named-skill move,
this branch vs main) is not runnable in-tree and must clear before merge.
2026-07-03 19:16:36 -07:00
Patrick Buckley fec5067fcd feat(skills): gate model-initiated load of high/critical-risk skills
A skill can auto-fire tools (auto_approve + allowed_tools) once loaded, so
letting the model activate a risky skill through skills(action='load') is an
injection-steerable lane that widens authority behind a rubber-stampable
approval. Deny it: high/critical-risk skills are now PRINCIPAL-load-only --
the model gets a clean error pointing the user at /skill, and the operator
loads such skills explicitly (handle_command /skill and cli --skill call
set_skill directly and bypass this gate).

The scanner-computed risk_level is the gate signal -- it already escalates for
the auto_approve + allowed_tools authority the create path warns about -- so no
new column or migration is needed. The check can only DENY, never widen, so it
is safe by construction (HYPOTHESIS.md Principle 7 / design section 5.5).

Remaining step-5 follow-ups, out of scope here: persisting the literal
disable-model-invocation frontmatter field for arbitrary author-marked skills
(needs a column) and deprecating the vestigial variables mechanism.
