Patrick Buckley 98e96ab5f3 Add per-alias model concurrency admission (#990)
* feat(models): add per-alias concurrency admission

Add registry-backed FIFO admission limits with queue-aware deadlines and full-stream leases. Expose max_concurrency through storage, admin configuration, OpenAPI, documentation, and diagrams, with role and live backend count coverage.

* fix(api): omit null concurrency schema default

Keep max_concurrency optional for presence-keyed updates without advertising a null default for its non-null integer OpenAPI shape.

Patrick Buckley 7a06f5e8bc refactor(session): make ModelLane the provider boundary (#979) (#989)
* refactor(session): make ModelLane the provider boundary (#979)

## Summary

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

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

Patrick Buckley 8605c9783d feat(models): rfc8693_obo auth mode, per-alias exchange scopes, identity-keyed mint cache
Adds the dedicated `rfc8693_obo` model auth mode (#955): model
definitions gain an `obo_scopes` column (migration 069), the mint
threads the scopes to the token-exchange leg (RFC 8693), and every
dynamic mode pins its grant leg — a mode is a dialect commitment, not a
hint the deployment profile resolves. Exchange-capable IdPs refuse an
audience whose scope was not requested; this closes the structurally
unmintable model-OBO path on token-exchange deployments.

The model mint-cache is identity-keyed on the owning definition's
alias (`__model_obo__:<alias>` per user, `__model_app__:<alias>` under
the shared app principal), matching the MCP discipline where rows key
on the unique server name. The bearer's shape lives in the row's
audience/scopes columns and the freshness gate compares it on every
read, so a re-aimed alias refuses its old row and overwrites the same
key in place. Admin lifecycle (rename, re-aim, scope change, delete)
purges a definition's own rows through one shared helper — sound
because one definition owns each key; a sibling's rows are untouchable
by construction. Cooldown and backoff additionally key on the dispatch
shape, so an operator's config repair is an instant clean slate. Cause
records, cooldowns, locks and memoization are per-alias end to end,
and the session heartbeat reads refusal causes under the same keys.

Console: default-deny write gating for dynamic rows (value-diff over
the full column ladder, admin.mcp escalation, a never-blockable
pure-disable carve-out), a two-tier validator (audience allow-list on
every write; deployment-posture checks when the pair is chosen), one
shared scopes parser whose omit-unchanged arm keeps over-cap DB-direct
residue rows disarmable without ungating real changes, and served
constraints (dynamic/scopes/app-identity mode lists, mode-to-profile
pairing) so the shelf tracks the registry by data. The admin shelf
gains the mode option, a scopes input with residue affordances,
pairing-aware option greying, and a derived auth badge.

Registry load refuses control characters in alias, audience, and
scopes — including the C0 separator block that str.split() would
silently collapse — and the C0/DEL class has one exported spelling
shared by every surface. Profile-mismatch visibility warns at reload
and boot with the mode-correct cause, gated on OIDC being enabled.

Breaking: a stored `entra_obo` alias on a deployment whose
`[oidc] obo_grant_profile` is `rfc8693` (or the inverse pairing) no
longer mints via the profile-driven overload — the mint refuses before
any IdP traffic with cause `grant_profile_mismatch`, and the
`model.auth_fail_closed` policy governs static fallback. Such rows
never minted usefully on scope-gating IdPs; the shelf now surfaces the
pairing and the per-turn heartbeat names the refusal cause.

Live-verified end to end: scoped token exchange mints, the warm cache
serves with zero IdP calls, and the mode/profile mismatch refuses with
zero IdP traffic (scripts/obo-e2e/keycloak_e2e.sh); the
refresh-redemption profile's E1-E7 hold via scripts/obo-e2e/entra_e2e.py.

Closes #955.

Patrick Buckley 33ace975d2 feat(models): default-deny governance and admin UI for per-alias backend auth
Follow-up to the per-alias Entra OBO/app-identity backend auth: the
console write path now applies default-deny field classification, the
admin shelf gains full backend-auth support, and the session/registry
rebind machinery is hardened for config changes landing under live
sessions.

Console write gate:
- Default-deny classification: any non-neutral change to a row that is
  or becomes dynamic requires admin.mcp plus validation; the provably
  auth-neutral columns are enumerated (MODEL_AUTH_NEUTRAL_FIELDS) and a
  live-schema classification test forces every future column to be
  classified. The derivation is a pure function (_derive_auth_gate)
  with unit-pinned exclusivity invariants.
- Two-tier validation mirroring the MCP oauth_obo validator: the row
  tier (audience allow-list) runs on every gated write; the posture
  tier (OIDC configured, token store present) runs on pair changes and
  on enable-arming.
- Pure-disable carve-out: disabling a dynamic row is de-escalation and
  is never blocked — admin.models suffices and validation is skipped,
  including for rows with corrupt or skewed stored values.
- Capabilities are compared canonically (key order, integral floats),
  the audience compare normalizes both sides, and staging an audience
  on a static row is refused on both write twins.
- Calibrate writes the capabilities column under an enforced
  confinement invariant with a compare-and-swap persist.

Admin shelf:
- Backend-auth section with a per-open constraints fetch
  (GET /model-definitions/auth-constraints: audience allow-list, grant
  profile, dynamic modes), datalist audience suggestions,
  server-defined modes preserved on round-trip, and permission-aware
  visibility built on cache-skew-safe helpers shared through auth.js.
- Refused live-registry swaps surface as an amber registry_warning on
  the write, delete, reload, and calibrate responses; audit rows carry
  auth_gated / auth_disarmed markers visible in the audit view.

Registry and sessions:
- The encryption-key requirement for dynamic auth is enforced inside
  ModelRegistry.reload() itself — nodes refuse with 503 and the
  console records coord_registry_error — and reload bumps the
  generation before the map swap so a racing reader can never pair a
  stale generation with new maps.
- resolve()/resolve_binding() return the generation from inside the
  registry lock; sessions rebind per send on generation change with
  atomic client/provider/config commits, fallback-first handling of
  removed or unconstructable aliases, and judge/limiter resets only
  when the binding actually changed.
- Mint refusals record per-user causes surfaced in the per-turn
  heartbeat logs; misconfiguration warnings are deduplicated with
  bounded state.

Verification: 10417 tests (99 added on this branch), a 71-scenario
browser harness over the real admin shelf, and a live rfc8693
token-exchange e2e run (MCP legs verified end to end; the model-leg
scope gap is tracked as #955 under a narrow known-gap signature).

Closes #950.

metaclassing 9adde920d4 feat(models): per-alias backend auth via Entra OBO and app identity (#898)
Adds a per-alias `auth_mode` on model definitions so a model backend can
authenticate to an Entra-fronted gateway with a per-request minted token instead
of one shared static API key, letting the gateway attribute calls to the actual
user or to the app as a machine identity.

- `static` (default, unchanged) sends the stored `api_key`.
- `entra_obo` mints a per-user On-Behalf-Of token for `obo_audience` from the
  caller's captured refresh credential.
- `entra_app` mints an app-identity token via the client-credentials grant, and
  covers userless turns that OBO cannot.

Reuses the existing OBO grant legs, refresh-token rotation CAS, cluster advisory
lock and the `mcp_user_tokens` mint-cache, keyed under synthetic
`__model_obo__:<audience>` / `__model_app__:<audience>` rows. The token binds at
the call site through `client.with_options(api_key=...)` so each SDK emits it on
its own auth path rather than through header injection.

Migration 068 adds `auth_mode` and `obo_audience`. Both are additive and existing
rows default to `static`, so behaviour is unchanged unless an alias opts in.

Operator controls: `model.auth_audience_allowlist` is an exact-match allow-list
that gates which audiences may be configured and denies all by default, and
changing a mode or audience requires `admin.mcp`. `model.auth_fail_closed`
decides whether a failed mint may fall back to an explicitly configured static
key. A delegated call with no user, or a dynamic alias with no real static key,
always refuses.

Two changes here apply regardless of whether any alias opts in:

- Storage and app state are now wired into the console MCP client manager. This
  fixes per-user `oauth_user` / `oauth_obo` dispatch for coordinator-hosted
  sessions, which previously raised `RuntimeError` on first call because
  `set_app_state` was only ever called on the node.
- Unattended watch restores and `--resume` resolve the persisted workstream
  owner instead of constructing the session under an empty principal. A
  workstream with no owner is now a permanent refusal rather than an anonymous,
  auto-approved run.

Patrick Buckley 03861e0cf5 feat(console): verbosity and reasoning-mode controls in the model shelf
- capability-gated "Response controls" on the Models create/edit
  shelf: Output verbosity (low/medium/high) and Reasoning mode
  (Standard/Pro), shown only for Responses-surface models; the empty
  selection means provider default and omits the capability key
- values lift out of the capabilities JSON into the selects on edit
  and merge back on save with identity tracking, so changing the
  provider/model/surface resets them instead of carrying a value
  across models; the Advanced JSON textarea wins unless the select
  was touched last
- known GPT-5.6 models inherit support from the static table without
  persisting redundant support flags; OpenAI-compatible models pinned
  to the Responses surface opt in via the supports_verbosity /
  supports_pro_mode tiles
- invalidate in-flight capability lookups on any identity field
  change and on modal open so a stale response cannot clobber a fresh
  shelf; API-surface changes now run the full field-change path
- model list rows surface verbosity= / mode= override chips

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 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 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 a917bf2690 docs: apply Copilot review feedback on PR #367
All eight suggestions verified against source before applying:

- docs/settings.md — ConfigStore key names are `model.plan_alias` /
  `model.task_alias` (not `plan_model` / `task_model`); updated in
  both the overview list and the plan/task overrides table.
- docs/security.md — `src` claim values now reflect what actually
  gets minted: `password`, `database` (from API-token exchange),
  `oidc`, plus service origins `console`, `cli`, `channel`.
- docs/sdk.md — `upload_attachment(ws_id, filename, data, *,
  mime_type=...)` matches the real SDK signature; `bytes`-returning
  helper is `get_attachment_content` (not `download_attachment`);
  code example reordered so it doesn't collide on `filename=` kwarg.
- docs/architecture.md — "prior `plan` tool call" → "prior
  `plan_agent` tool call" so wording stays consistent with the
  renamed tool.
- docs/tools.md — `plan_agent` `primary_key` is `goal`, not
  `prompt`, in both the primary-key table and the summary table
  (matches the JSON schema in turnstone/tools/plan_agent.json).

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 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 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 101afd84da feat: database-backed settings (ConfigStore) with admin API (#59)
* 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.

warn_migrated_settings() logs warnings for config.toml keys that
overlap with ConfigStore-managed settings.

Console admin API: GET /v1/api/admin/settings (list with effective
values), GET .../schema (registry catalog), PUT .../{key} (update),
DELETE .../{key} (reset to default).  Audit trail on mutations.

MQ: ConfigChangeEvent for cross-node cache invalidation (emission
from console deferred to bridge integration).

Python + TypeScript SDK methods.  63 new tests.  Feature docs at
docs/settings.md, PlantUML diagram 24-settings-architecture.

* 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 ("***")
