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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix: add list_ws_templates SDK methods + regenerate OpenAPI snapshots

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

Addresses Copilot review feedback on PR #67.

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

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

Patrick Buckley 2ef8a8711b feat: rich markdown renderer with LaTeX support for server web UI (#65)
* feat: rich markdown renderer with LaTeX support for server web UI

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

Security: escape image/link URLs to prevent attribute injection, block
javascript: scheme in links, add rel="noopener noreferrer", images
require explicit click to load (no automatic external requests).

Accessibility: scope="col" on table headers, tabindex on scrollable
table containers, aria-labels on task checkboxes and image placeholders,
KaTeX error color override for WCAG AA contrast, reduced-motion support.

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

- Escape all text through escapeHtml() at start of inlineMarkdown()
  so only renderer-generated tags appear in innerHTML (prevents raw
  HTML/script injection from LLM output)
- Replace inline onclick handler on image placeholders with data-*
  attributes and delegated DOM event listeners (prevents entity
  decoding XSS in event handler attributes)
- Split list blocks into separate <ul>/<ol> when marker type changes
  at the same indent level (mixed ordered/unordered sequences)

Patrick Buckley 3658b77de8 feat: Discord content catch-up + bidirectional notification replies (… (#64)
* feat: Discord content catch-up + bidirectional notification replies (#64)

Two improvements to the Discord channel adapter:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

66 new tests (2232 total).

* fix: address Copilot review feedback on MCP admin PR

- Docs: fix "merges both sources" → "first-match-wins priority" (architecture.md)
- Validation: require command for stdio, url for streamable-http transport
- Validation: check args/headers/env types in import handler before storing
- Schema: add transport/command/url to McpServerStatus, source to McpServerDetail
- Thread safety: move all remove_server_sync mutations onto MCP event loop thread
- Regenerate OpenAPI JSON snapshots for TypeScript SDK

* feat: admin Settings tab — form-based editor replacing "coming soon" stub

Section-grouped layout with collapsible headers for all ~40 ConfigStore
settings (model, session, tools, server, mcp, ratelimit, health, judge,
memory). Type-appropriate inputs: CSS toggle for bools, number with
min/max/step, select for choices, text for strings. Secret fields shown
read-only. Source badge (storage/default), amber restart indicator.

Inline save per field with dirty detection, row flash on success, reset
to default via styled confirm modal. Full WCAG keyboard accessibility
(Enter/Space on section headers, aria-labels, focus-visible). Mobile
responsive single-column at <700px. Reduced-motion safe.

* fix: Settings tab polish — help tooltips, context_window auto-detect, UX fixes

Settings UI:
- Help tooltips: ? button on ~25 settings with plain-English explanations
  and optional reference links (arXiv, Fowler, MCP spec). Click to toggle
  popover, Escape to dismiss, aria-expanded for accessibility.
- Sections start collapsed for scannable overview.
- Restart badge: hidden by default, shows when dirty, persists after save
  with amber glow. Positioned left of source badge.
- Secret row alignment fixed (transparent border matches input box model).
- Docs link in toolbar → Swagger UI Settings section.
- Number inputs: spin buttons hidden (Firefox/WebKit), empty value guard,
  numeric dirty detection (0.1 vs 0.10 no longer false positive).
- Secret reset button enabled when source=storage (clear legacy overrides).
- Space key repeat guard on section headers.
- Sidebar: sticky + max-height:100vh, no longer stretches with content.

Backend:
- context_window default changed from 131072 to 0 (auto-detect). Fallback
  lowered from 131K to 32K (realistic for local models when detection fails).
  Session normalizes 0→32768 defensively.
- Settings registry: help + reference_url fields on SettingDef, richer
  descriptions for model/session/tools/judge/memory settings.
- Schema API includes help + reference_url.
- Bootstrap system prompt: added Runtime Settings section.

Docs: tab counts updated to 13 across README, architecture, console, governance.

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 ("***")

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

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

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

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

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

TypeScript SDK: matching methods + types on both clients.

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

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

Also fixes stray `total: int` on CreateChannelUserRequest.

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

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

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

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

6 new security tests for user-scope access control.

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

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

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

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

113 new tests (2053 total).

* fix: CI failure + copilot review feedback

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

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

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

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

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

* fix: address PR #50 Copilot review feedback

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

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

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

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

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

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

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

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

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

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

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

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

* fix: address PR #49 review feedback

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

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

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

* feat: wire prompt templates into session startup with full creation-path support

Prompt templates (prompt_templates table) now have runtime effect:

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

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

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

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

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

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

* fix: address PR #47 review feedback

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

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

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

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

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

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

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

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

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

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

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

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

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

Prompt listener registered in session for catalog rebuild on changes.

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

Docs and diagrams updated for 18 built-in tools.

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

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

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

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

* feat: MCP visibility in server and console UIs

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

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

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

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

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

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

* fix: OpenAPI spec McpStatus + diagram approval column accuracy

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

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

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

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

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

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

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

MQ: CancelMessage inbound type, bridge _handle_cancel routed handler.

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

OpenAPI: CancelRequest schema + endpoint spec.

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

* fix: address PR #40 review feedback

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

* feat: governance — RBAC, tool policies, prompt templates, usage tracking, audit logging

Add comprehensive governance layer for the admin console:

- RBAC with 15 granular permissions, 3 builtin roles (admin, operator, viewer),
  custom role CRUD, user-role assignment with privilege escalation prevention
- Tool policies with glob pattern matching, priority-ordered evaluation
  (allow/deny/ask), enforced before auto-approve in WebUI.approve_tools()
- Prompt templates with variable substitution, categories, default flag
- Usage tracking: per-LLM-request token/tool metrics, aggregated queries
  (group by day/model/user), automatic 90-day pruning via scheduler
- Audit logging: append-only event trail for all admin mutations,
  filterable/paginated queries, automatic 365-day pruning, X-Forwarded-For
  aware IP extraction
- require_permission() enforced on all 35+ admin endpoints (users, tokens,
  channels, schedules, watches, roles, orgs, policies, templates, usage, audit)
- Field allowlists on storage update methods prevent mass-assignment bugs
- Self-deletion guard on admin_delete_user, delete_user cascades user_roles
- _row_to_dict helper eliminates ~400 lines of fragile positional row mapping
- _audit_context helper deduplicates 18 instances of audit boilerplate
- Migration 008: 7 new tables, 3 builtin roles, org_id on users
- Console admin panel: 5 new tabs (Roles, Policies, Templates, Usage, Audit)
  with permission-gated visibility, 7 modal dialogs, full keyboard accessibility
- Python + TypeScript SDK methods for all governance endpoints
- 120+ new tests (1554 total)

* fix: address PR #39 review feedback

- Rebuild serialized items after policy evaluation so denied/allowed
  verdicts are reflected in tool_info/approve_request SSE payloads
- Make `since` query param optional in usage OpenAPI spec (handler
  already defaults to last 7 days)
- Add response_model=StatusResponse to DELETE role/policy/template
  and POST/DELETE role assignment endpoints in OpenAPI spec
- Add missing org_id/created/updated fields to UserRoleInfo schema
- Add missing created field to AuditEventInfo schema
- Show "no permissions" empty state instead of loading inaccessible
  tab when all admin tabs are permission-gated
- Fix "13 permissions" → "15 permissions" in architecture.md and
  security.md
- Fix import sorting in test_audit.py and test_tool_policy.py

* fix: address PR #39 round 2 review feedback

- Clear stale permissions from sessionStorage on config-token login
  (auth.js _storePermissions)
- Only trust X-Forwarded-For when behind a proxy that sets
  X-Forwarded-Proto (conditional on is_secure_request trust model)
- Thread user_id from auth into WebUI.on_status for usage events
- Add created field to TS AuditEventInfo type
- Return typed Pydantic models from all SDK governance methods instead
  of dict[str, Any] — both async and sync clients
- Validate group_by param against allowed enum in admin_usage handler
- Add deterministic secondary sort (event_id DESC) to
  list_audit_events in both SQLite and PostgreSQL backends

* fix: per-workstream SSE fan-out — multiple consumers no longer steal each other's tokens

After 4d665a5 removed the single-consumer SSE lock, the shared
_event_queue let concurrent consumers (browser, bridge, console proxy)
race on Queue.get(), each receiving ~1/N of content tokens and producing
garbled streaming text.

Replace the single queue with per-client fan-out: each SSE connection
registers its own bounded queue (maxsize=500) on WebUI._listeners, and
_enqueue() copies every event to all registered queues. On eviction or
close, a ws_closed sentinel is injected so SSE generators exit promptly.

* fix: address CI failures and Copilot review feedback

- Handle ws_closed sentinel in events_sse generator (break on close)
- Guarantee sentinel delivery by evicting one item when queue is full
- Clear listeners list after injecting sentinels on cleanup
- Fix test_slow_consumer to fill only slow queue directly
- Fix ruff SIM117 (nested with), unused import, mypy unused-ignore

Patrick Buckley 187d004033 feat: watch tool — periodic command polling within workstreams (#36)
* feat: watch tool — periodic command polling within workstreams

Add a new `watch` tool that lets the model (or user) set up periodic
polling of a shell command. Results inject as synthetic user messages
that trigger LLM turns, enabling reactive workflows like PR monitoring,
CI/CD status tracking, and deployment health checks.

Key design:
- Single tool with create/list/cancel actions
- Python expression DSL for stop conditions (restricted eval)
- Server-owned WatchRunner daemon (DB-persisted, survives eviction + restart)
- Three dispatch paths: idle, busy, and evicted workstream restore
- REST API for console visibility (GET /v1/api/watches, POST cancel)
- Migration 007, 8 storage CRUD methods, 75 new tests (1383 total)

* fix: address Copilot review — condition errors, restore deadlock, docs

- Condition eval errors now deactivate the watch immediately instead
  of silently looping until max_polls
- Restored (evicted) workstreams set auto_approve=True to prevent
  approval deadlocks with no connected user
- Tool description clarifies first-poll baseline behavior for change
  detection mode
- Diagram updated: DELETE → POST /v1/api/watches/{id}/cancel

Patrick Buckley 3bc3250869 fix: recovered workstreams invisible in console UI (#35)
* fix: recovered workstreams invisible in console UI

Bridge startup recovery (_recover_workstreams) re-registered workstream
ownership but never published WorkstreamCreatedEvent to the cluster
channel. The collector's poll loop would pick up the workstream in its
internal state, but _apply_poll never fanned out SSE events to connected
browsers. Combined, this made channel-resumed workstreams invisible in
the console while remaining accessible through the proxied node UI.

- Bridge: emit WorkstreamCreatedEvent for each recovered workstream
- Collector: diff poll results and fan out synthetic ws_created/ws_closed
  events for workstream additions and removals
- Skip workstreams with empty IDs in poll processing
- Add 4 tests for poll-diff fanout behavior
- Update console data-flow diagram and architecture docs

* fix: address PR review — filter empty ws IDs, stable event ordering

- Filter empty-string keys from old_ids to avoid phantom ws_closed
  events if a previous poll inserted a workstream under key "".
- Sort set diffs before iterating so ws_created/ws_closed fanout
  order is deterministic across poll cycles.

Patrick Buckley 5f0004dc91 feat: add ClusterSnapshot for instant console UI state rebuild (#34)
* feat: add ClusterSnapshot for instant console UI state rebuild

The console web UI was SSE-driven with no initial state — reloads and
navigation caused blank/loading gaps while waiting for API re-fetches.

Server-side: GET /v1/api/cluster/snapshot returns the full cluster state
(all nodes with workstreams + overview aggregates) built under a single
lock. The SSE stream now emits this snapshot as the first event on
connect (snapshot taken before listener registration to avoid race).

Frontend: local clusterState object mirrors the snapshot, patched
incrementally by SSE events. View navigation renders from local state
with no API round-trips. Fixes popstate/pushState history corruption
on Back/Forward navigation (pre-existing bug). Stable node sorting
with node_id tie-breaker on both server and client.

SDK: snapshot() method on Python (sync + async) and TypeScript console
clients. ClusterSnapshotEvent in event registries.

* fix: address review feedback and SSE proxy reconnect bug

Copilot review fixes:
- Atomic snapshot+register: new get_snapshot_and_register() acquires
  both state and listener locks, eliminating the event gap between
  snapshot read and listener registration.
- Debounce patch renders: patchClusterState uses requestAnimationFrame
  to batch rapid SSE events into a single recompute+render cycle.
- Fix health type: dict[str, str] → dict[str, Any] on all three
  console schema models (ClusterNodeInfo, NodeDetailResponse,
  ClusterSnapshotNode) since /health payloads contain nested objects.
- TypeScript ClusterSnapshotEvent: use concrete ClusterSnapshotNode[]
  and ClusterOverviewResponse types instead of Record<string, unknown>.

SSE proxy reconnect fix:
- _proxy_sse raw_stream now emits `: proxy-ping` comments every 3s
  when no upstream data arrives, preventing the browser EventSource
  from dropping idle connections. The raw byte passthrough refactor
  (4d11078) removed the proxy's independent keepalive — this restores
  it without reverting to EventSourceResponse.

Patrick Buckley 6cc1b3a5bd feat: add vision/image support to read_file tool (#33)
* feat: add vision/image support to read_file tool

read_file now detects image files (PNG, JPEG, GIF, WebP, BMP, TIFF, ICO)
and returns base64-encoded content parts for vision-capable models.
Non-vision models receive a text description instead. A new
supports_vision flag on ModelCapabilities gates the feature, with
config.toml [models.*.capabilities] overrides for local models
(vLLM, llama.cpp, NIM).

* fix: address PR review feedback

- Discard _read_files on no-vision OSError path, include exception detail
- Discard _read_files on oversized image error (not a successful read)
- Validate capabilities type from config.toml (reject non-dict)
- Clarify tool description re: vision behavior and offset/limit scope
- Remove unused os import in tests, fix import sort order
- Handle list content (image tool results) in eval.py tool result loop

- Stream bytes verbatim to preserve server-side ping comments and event framing
- Add StreamingResponse with proper headers (Cache-Control, X-Accel-Buffering)
- Update compose.yaml to add 'cluster' profile to the service

* Refactor SSE proxy to raw byte passthrough

- turnstone/console/server.py: Replace aconnect_sse + EventSourceResponse with
  httpx.stream() + StreamingResponse for raw byte passthrough. Server pings,
  events, and comments now flow through verbatim. Added per-request timeout
  override (read=None, pool=None) for long-lived SSE streams.

- tests/test_console.py: Add 3 new tests for SSE proxy:
  - Ping and event preservation
  - Upstream error status handling
  - Client disconnect handling

- docs/console.md: Update SSE Proxy section to reflect raw byte passthrough
  approach.

* Add MCP dynamic tool refresh with push notifications and periodic polling

MCP tool lists now stay up-to-date without restart via three mechanisms:
push notifications (ToolListChangedNotification) for servers that support
it, staggered periodic polling for servers that don't, and manual
/mcp refresh [server] command. MCPClientManager tracks tools per-server
with copy-on-write rebuild, notifies ChatSession listeners which rebuild
tool lists and ToolSearchManager (preserving expanded tools).

* Address Copilot review feedback on MCP refresh PR

- Fix /mcp refresh typo matching (startswith → exact token check)
- Validate --mcp-refresh-interval >= 0 at parse time via shared
  nonneg_float in config.py (deduplicated from cli.py + server.py)
- Clamp negative refresh_interval to 0 in MCPClientManager constructor
- Fix periodic refresh first poll timing (was initial_delay + interval,
  now initial_delay then immediate first poll)
- Clarify _on_mcp_tools_changed docstring re: O(n) BM25 build cost

Patrick Buckley c7586abd0a Add dynamic tool search with native defer_loading for Anthropic/OpenAI (#30)
* Add dynamic tool search with native defer_loading for Anthropic/OpenAI

When MCP tools push the total tool count past a configurable threshold
(default 20), tool definitions are deferred to reduce token overhead and
improve tool selection accuracy. Three-tier approach mirrors the existing
web search pattern:

- Anthropic (Claude 4.x): native defer_loading + server-side BM25 search
- OpenAI (GPT-5.4+): native defer_loading + hosted search
- vLLM/llama/NIM: client-side BM25 fallback via synthetic tool_search tool

New module turnstone/core/tool_search.py with BM25Index (pure-Python,
zero deps) and ToolSearchManager (session-scoped visibility, expansion,
server hint generation). Discovered tools persist for the session lifetime
so the model only searches once per capability needed.

Config: [tools] search/search_threshold/search_max_results
CLI: --tool-search {auto,on,off}, --tool-search-threshold, --tool-search-max-results
Agents (plan/task) exempt — their scoped tool sets are always small.

43 new tests (1253 total). All diagrams regenerated with PlantUML 1.2025.2.

* Fix Copilot review feedback on tool search

- Fix _MCP_PREFIX_RE to handle underscores in server names (non-greedy match)
- Use ordered dict for _expanded to preserve tool discovery order
- Avoid constructing ToolSearchManager when below threshold in auto mode
- Return empty string from _mcp_server_summary when no servers (not "none")
- Fix CLI help text to reference threshold generically, not hardcoded "20"
- Fix agent exemption docs to accurately describe scoped tool sets
- Fix README to not hardcode "30+" threshold number

Patrick Buckley fb190f8977 Normalize session_id into ws_id as sole persistent identity (#29)
* Normalize session_id into ws_id as sole persistent identity

Eliminate the separate session_id concept. The workstream ID (ws_id) is
now the single identity used for both real-time routing and conversation
persistence, removing a layer of indirection that was 1:1 in practice
and buggy on resume (stale pointers, orphaned rows).

Schema changes (migration 006):
- Drop sessions table; add alias/title columns to workstreams
- Rename conversations.session_id → ws_id
- Rename session_config table → workstream_config (ws_id column)
- Data migration remaps existing conversations to ws_id

Storage/API renames:
- register_session → register_workstream (already existed, merged)
- save_message/load_messages now keyed by ws_id
- resolve_session → resolve_workstream
- ChatSession.session_id property → ws_id
- ChatSession.resume_session() → resume()
- resume_session field → resume_ws
- SessionResumedEvent → WorkstreamResumedEvent
- /api/sessions → /api/workstreams/saved
- /sessions slash command → /workstreams
- --session-retention-days → --retention-days

Channel eviction recovery simplified: reuses old ws_id directly
instead of get_session_id_by_ws() reverse lookup.

* Fix Copilot review feedback: stale session wording in docs, regenerate OpenAPI spec

- docs/channels.md: "resumes the session" → "resumes the workstream",
  "Session resumed:" → "Resumed:", "old session was pruned" → "old
  workstream was pruned"
- docs/api-reference.md: "Each session object" → "Each saved workstream
  object", field descriptions updated, removed stale node_id field
- sdk/typescript/openapi-server.json: fully regenerated from Python

* Add channel notification tool with security hardening

Implements the `notify` tool allowing the LLM to send notifications to
Discord channels/users via the channel gateway. Includes fixes for 11
review findings: JWT auth on the gateway endpoint, first-healthy gateway
delivery with retry+backoff, rate limiting only on success, SSRF URL
scheme validation, Discord mention sanitization, SQLite ON CONFLICT
upsert preserving created timestamps, advertise URL resolution for
0.0.0.0 bind, randomized service IDs, generic error messages to prevent
internal state leakage, and partial direct-target validation.

Service registry with heartbeat-based health filtering (migration 005).
Channel gateway registers on startup, heartbeats every 30s, deregisters
on shutdown. 70 new tests covering tool prepare/execute, HTTP endpoint
auth (static + JWT), storage CRUD, and retry behavior.

* Add notify documentation, diagrams, and review fixes

Documentation:
- New sequence diagram 17-notify-flow.puml showing end-to-end delivery
- Updated 16-channel-architecture.puml with services table, notify HTTP
  path, and Notification Flow note
- channels.md: Notifications section (targeting, delivery flow, service
  registry, security) and new config table entries
- tools.md: notify tool reference, updated counts/tables (14→15 tools)
- security.md: channel gateway row in service-to-service auth table
- architecture.md: notification subsystem paragraph

Review fixes (copilot):
- _http.py: fail closed when auth unconfigured (401 instead of pass-
  through), strip whitespace on message/title, generic error messages
  for user-not-found vs no-linked-channels
- session.py: parse gateway response JSON and require at least one

* Add channel integrations with Discord adapter and atomic session resume (#24)

Bidirectional channel adapter framework connecting external messaging
platforms to turnstone workstreams via Redis MQ. Discord ships as the
first adapter; the protocol supports future Slack/Teams integrations.

Channel framework:
- ChannelAdapter protocol and ChannelRouter for channel↔workstream mapping
- AsyncRedisBroker with single dispatch loop and per-channel ordered workers
- channel_routes table (migration 003) for persistent route storage
- 9 new StorageBackend methods (4 channel_user + 5 channel_route CRUD)
- Unified turnstone-channel gateway entry point, loads adapters by config
- Message chunking, approval formatting, plan review formatting

Discord adapter:
- discord.py v2.4+ bot with thread-per-@mention model
- Slash commands: /link (modal), /unlink, /ask, /status, /close
- Persistent button views for tool approval and plan review
- Streaming responses via edit-in-place (1.5s interval)
- Stale route detection and atomic session resume via resume_session field
- SessionResumedEvent confirmation back to channel
- Auto-approve support (blanket + per-tool list)

Atomic session resume:
- resume_session field on CreateWorkstreamMessage for single-request resume
- Server resumes session during POST /v1/api/workstreams/new atomically
- Bridge emits SessionResumedEvent to per-workstream channel
- WorkstreamCreatedEvent extended with resumed/session_id/message_count
- Server UI dashboardResumeSession simplified to single request
- Pruned sessions fall back gracefully to fresh start

Service auth:
- Bridge and console auto-mint service JWTs from TURNSTONE_JWT_SECRET
- Bridge: approve scope (1 week). Console collector: read. Proxy: write.

Console admin:
- Channels tab with per-user view, force-link modal, unlink
- 3 admin API endpoints for channel user management
- Styled confirm modals replacing browser confirm() dialogs

Bug fixes:
- AsyncRedisBroker: replaced per-channel listener tasks with single
  dispatch loop + per-channel queue workers (fixes message stealing race)
- Bridge: approval/plan review dedup guard prevents SSE reconnect duplicates
- Bridge: _active_sends tracked for initial messages (fixes missing
  TurnCompleteEvent and unfinalized streaming messages)
- Bridge: HTTP calls moved outside lock scope in approval handlers
- Bridge: _handle_send cleans up _active_sends on HTTP/server errors
- Formatter: reads server SSE format (func_name/preview) with fallback

Docs, SDK, tests:
- docs/channels.md setup guide, architecture diagram 16
- Updated api-reference.md, architecture.md, console.md, docker.md
- Python SDK: resume_session param on create_workstream (async + sync)
- TypeScript SDK: updated CreateWorkstreamRequest/Response interfaces
- OpenAPI schema: resume_session request, resumed/message_count response
- 91 new tests (19 storage, 15 broker, 22 protocol, 6 routing,
  18 discord, 12 resume flow) — 1120 total passing

admin channel create, support SSE format in auto-approve check, update
identity linking note in architecture diagram.

* Fix remaining mypy call-arg errors for discord.py optional dependency

Add type: ignore[call-arg] on Modal(title=) and Cog(name=) class
definitions that fail when discord.py is not installed in CI.

Patrick Buckley 047680d669 Add user identity, JWT auth, and admin console UI (#23)
* Add user identity, JWT auth, and admin console UI (#23)

JWT-based authentication with three token types: config-file (hmac,
backward-compat), API tokens (ts_ prefix, SHA-256 hashed), and JWTs
(HS256, 24h expiry). Username:password login via bcrypt. Hierarchical
scopes: read < write < approve.

New tables: users (username, password_hash), api_tokens (token_hash,
scopes, expires), channel_users (future channel integrations). user_id
column added to sessions and workstreams for attribution.

Console owns admin CRUD (6 endpoints under /api/admin/). Server
validates JWTs locally with shared signing secret. Public /api/auth/setup
endpoint for first-time admin creation (atomic, only works with zero
users). turnstone-admin CLI for user/token management.

Admin console UI: Users and Tokens tabs with full CRUD modals, scope
badges, token show-once with clipboard copy, keyboard accessibility
(focus traps, Escape, arrow key tabs, ARIA roles).

Login UI redesigned: username:password primary, token toggle for legacy,
setup wizard auto-detected via /api/auth/status. Python + TypeScript
SDKs updated with login(username, password), authStatus(), setup().

New docs/security.md + diagram 15-auth-architecture.puml. All existing
docs updated. OpenAPI specs include all new endpoints. 64 new tests
(1023 total). Dependencies: PyJWT, bcrypt.

* Fix auth bugs, XSS vector, and doc inaccuracies from PR #23 review

Address Copilot review feedback: escape double quotes in escapeHtml()
to prevent XSS in HTML attributes, add JWT validation fallback so

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

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

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

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

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

* Address PR #22 review feedback

- Fix CLI session_factory signature (ws_id param) — CI typecheck failure
- First-phase eviction in create() now calls _cleanup_ui + record_eviction
- close() persists "closed" state to storage via update_workstream_state

Patrick Buckley e057c364b8 Fix console proxy regressions and add workstream task field (#21) (#21)
* Fix console proxy regressions and add workstream task field (#21)

Bug fixes:
- Fix collector polling unversioned /api/dashboard (404 after API
  versioning PR) — nodes showed red/unreachable, no workstreams
- Fix SSE proxy dropping all data events — upstream sends \r\n line
  endings but proxy split on \n\n only; normalize before parsing
- Fix workstream state stuck on idle — on_state_change() only
  broadcasted via SSE but never updated ws.state on the Workstream
  object; dashboard polling now sees correct attention/running states
- Fix deep-link switchTab early return — when ?ws_id matched the
  only workstream, switchTab bailed (wsId === currentWsId) before
  establishing SSE connection; inline init instead of delegating
- Fix console banner covering dashboard overlay — inject <style>
  offsetting .dashboard-overlay below the 32px banner

Enhancements:
- Add turnstone branding to console proxy banner (turnstone │ Console │ node-id)
- Add initial_message field to CreateWorkstreamMessage protocol and
  console "New Workstream" modal (Task textarea, sent as first message)
- Refactor SSE proxy to use shared httpx client with 30s read timeout
  instead of per-request client creation
- Increase approval timeout default from 300s to 3600s (1 hour)

Updated: Python SDK, TypeScript SDK, OpenAPI specs, MQ client,
API schemas, MQ protocol diagram, SDK docs.

* Address PR #21 review feedback (4 items)

- Log unknown state strings in on_state_change instead of silently
  swallowing; remove unnecessary KeyError catch
- Wrap initial_message POST in _handle_create_ws with error handling
  so workstream creation success isn't masked by send failure
- Strip all \r from SSE chunks instead of replacing \r\n, fixing
  chunk-boundary split edge case
- Add tests for initial_message wiring in directed and pool targeting

* Refactor SSE proxy to use httpx-sse aconnect_sse

Replace manual SSE chunk buffering/parsing with httpx_sse.aconnect_sse()
which handles line endings, event types, and all SSE spec edge cases.
Eliminates the \r\n chunk-boundary bug class entirely. Event types are
now always forwarded (sse.event defaults to "message" per spec).

* Add pluggable storage backend (SQLite + PostgreSQL) and deployment packaging

Database abstraction: StorageBackend protocol with 21 methods, SQLAlchemy Core
schema, SQLite backend (FTS5), PostgreSQL backend (tsvector/ILIKE), Alembic
migrations, singleton registry. memory.py reduced to thin facade. Session.py
open_db() calls replaced with generic KV methods. [database] config section
with env var support.

Deployment: Docker Compose production profile with PostgreSQL, Dockerfile with
postgres extras and migration entrypoint, Helm chart with bitnami subcharts,
Terraform AWS ECS/Fargate module with RDS + ElastiCache + ALB.

39 new storage tests (934 total). mypy strict clean. Docs and diagrams updated.

* Address PR #20 review feedback (16 items)

- Backends only call create_all() when Alembic migrations are disabled
- Helm configmap uses correct TURNSTONE_DB_BACKEND env var; DB URL
  constructed via env expansion with secret reference instead of ConfigMap
- Migration errors fail fast for PostgreSQL (only non-fatal for SQLite)
- save_memory/delete_memory wrapped in exception handling like other facade fns
- pool_size passed through from config/env to init_storage() in cli + server
- Terraform: DB URL moved to Secrets Manager, auth enabled flag set,
  optional TLS listeners with certificate_arn, Redis transit encryption on
- Docker entrypoint no longer suppresses migration output
- Diagram fixes: removed StaticPool claim, removed non-existent migration ref
- compose.yaml/README: clarified production profile requires DB env vars

* Add Python and TypeScript client SDKs for server and console APIs

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

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

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

* Address PR #19 review feedback + fix lint

Patrick Buckley 62a4ceac96 Dev/api versioning openapi (#18)
* Add API versioning under /v1/ prefix with OpenAPI 3.1 spec

All API endpoints move to /v1/api/* (clean break, no unversioned
aliases). Non-API routes (/, /health, /metrics, /static, /shared,
/node proxy) stay unversioned.

New turnstone/api/ package:
- Pydantic v2 models for all request/response schemas (server +
  console) used for OpenAPI spec generation
- Programmatic OpenAPI 3.1 spec builder with EndpointSpec catalog
- /openapi.json serves machine-readable spec, /docs serves Swagger UI

Route changes:
- Both servers use Mount("/v1", routes=[...API routes...])
- Auth middleware strips /v1/ prefix before path classification
  (PUBLIC_PATHS/WRITE_PATHS stay unversioned internally)
- Console proxy handles /node/{id}/v1/api/ upstream forwarding
- Bridge and CLI HTTP clients updated to /v1/api/ paths
- /openapi.json and /docs added to PUBLIC_PATHS and rate limiter
  EXEMPT_PATHS

Security fix from review: required_role() now correctly handles
/node/{id}/v1/api/{path} proxy routes (previously the v1 segment
caused write-path detection to fail, allowing read-only token
escalation).

42 new tests (830 total). All frontend JS, docs, and diagrams updated.

* Fix mypy type errors in turnstone/api/ package

- Add generic type params to dict fields in console_schemas.py
- Add return type annotations to docs.py handler factories
- Move type-only imports (BaseModel, Callable, Awaitable) into
  TYPE_CHECKING blocks to satisfy TC002/TC003 ruff rules

* Address PR #18 review feedback + fix mypy errors

Review fixes:
- Add pydantic>=2.0 as explicit dependency in pyproject.toml
  (was only transitively available via openai/mcp)
- Auto-detect path parameters from {param} segments in OpenAPI
  spec builder (fixes missing required path params)
- Use startswith() with concrete prefix for proxy version
  detection instead of fragile substring check
- Make Swagger UI base URL configurable via swagger_ui_base_url
  parameter for air-gapped deployments

Mypy fixes:
- Add generic type params to dict fields in console_schemas
- Add return type annotations to docs.py handler factories
- Move type-only imports into TYPE_CHECKING blocks

Patrick Buckley 29c00c0cdf Extract shared frontend design system into turnstone/shared_static/ (#17)
* Extract shared frontend design system into turnstone/shared_static/

The server UI and console UI had ~60% CSS overlap and significant JS
duplication. Extract shared assets into a new turnstone/shared_static/
package mounted at /shared/ in both servers:

- base.css: design tokens, reset, typography, login/toast/kb overlays,
  dashboard table, state dots, health bar, scrollbar, reduced motion
- auth.js: authFetch, login overlay with focus trap, logout (hooks for
  page-specific post-login/logout callbacks)
- theme.js: dark/light toggle with system preference detection
- toast.js: notification queue with configurable timeout
- utils.js: escapeHtml, formatTokens, ctxClass, formatUptime, formatCount
- kb.js: keyboard shortcuts overlay with configurable content, focus
  management, and focus restore on dismiss

Console proxy updated: JS shim injection moved from proxy_static (app.js
prepend) to proxy_index (inline <script> in HTML) so it runs before any
external scripts. New /shared/ path rewriting and proxy_shared_static
route added. ~1540 lines removed from page-specific files, 775 lines in
shared package. 13 new tests (788 total).

* Fix /shared/ auth and remove __init__.py from shared_static

Address PR #17 review feedback:

1. Add /shared/ to PUBLIC_PREFIXES in auth.py so shared CSS/JS
   loads before authentication (required for login overlay to render)

2. Remove turnstone/shared_static/__init__.py to prevent exposing
   Python package internals (__init__.py, __pycache__) via the
   StaticFiles mount. Not needed for packaging since pyproject.toml
   uses explicit glob includes.

3 new auth tests for /shared/ public path access.

Patrick Buckley b6e0f0fcca Add node version tracking and drift detection to console dashboard (#16)
* Add node version tracking and drift detection to console dashboard

Surface the version field from each node's /health endpoint in the
console dashboard. Collector extracts version into get_overview()
(version_drift + versions fields), promotes it to top-level in
get_nodes(), and adds get_version_info() for per-node detail. Console
/health endpoint includes drift fields.

Frontend adds a VER column to the 7-column node table grid, shows
per-node version strings, tracks versions per group with "mixed" +
yellow drift badge when nodes disagree, and displays a DRIFT warning
or single version in the status bar. Column hidden on mobile (<700px).
ARIA labels include version info for accessibility.

10 new tests (745 total). Docs and diagram updated.

* Fix drift tooltip text: show 'Versions detected' not 'Nodes running'

Patrick Buckley 206e37e73e Fix circuit breaker, rate limiter, and Anthropic web search correctne… (#15)
* Fix circuit breaker, rate limiter, and Anthropic web search correctness (#15)

Three tech debt items addressing correctness and security gaps:

Circuit breaker HALF_OPEN single-request permit:
- Rename should_allow_request property to acquire_request_permit() method
  to make the side-effecting, non-idempotent nature explicit
- Add _half_open_permit flag: exactly one probe request in HALF_OPEN,
  subsequent callers blocked until probe completes
- Explicitly reset permit on all state transitions (record_success,
  record_failure) for clean state machine invariants
- Session uses BaseException catch to ensure record_failure always fires,
  preventing permanent circuit deadlock on probe crash

Rate limiter X-Forwarded-For support:
- Add resolve_client_ip() with rightmost-untrusted XFF parsing
- Configurable trusted_proxies via --ratelimit-trusted-proxies CLI flag
  and [ratelimit] trusted_proxies config (comma-separated CIDRs)
- IPv4-mapped IPv6 normalization (::ffff:x.x.x.x → IPv4) for dual-stack
- Clientless requests (request.client is None) pass through instead of
  sharing a single "unknown" bucket
- Log warning for invalid CIDR entries in trusted_proxies config
- Show trusted proxies in startup log when enabled

Anthropic web search multi-turn encrypted content:
- Capture raw provider content blocks during streaming via _block_to_dict()
  using model_dump(exclude_none=True) to avoid Anthropic API rejection
- Accumulate thinking_delta into raw_blocks (was silently empty on replay)
- Store _provider_content on assistant messages, pass through verbatim in
  _convert_messages() so encrypted_content/encrypted_index survive turns
- Persist to SQLite via new provider_data column (auto-migrated)
- Add thinking/signature to _block_to_dict fallback attribute list

23 new tests (735 total), ruff + mypy clean.

* Fix Copilot PR #15 review issues: provider data, circuit breaker, IP normalization

- Persist assistant message when provider_data exists even if text
  content is empty — prevents losing Anthropic web search encrypted
  content needed for multi-turn replay (session.py)
- Re-raise KeyboardInterrupt/SystemExit immediately after recording
  failure instead of attempting fallback models (session.py)
- Consume HALF_OPEN permit for the transition caller — prevents two
  concurrent probe requests when only one should be allowed
  (healthcheck.py)
- Normalize IPv4-mapped IPv6 addresses consistently in
  resolve_client_ip() — prevents duplicate rate-limit buckets for
  ::ffff:x.x.x.x vs x.x.x.x (ratelimit.py)

Patrick Buckley 6c5441435b Add console workstream creation + server reverse proxy (#14)
* Add console workstream creation + server reverse proxy (#14)

Enable the console dashboard to create workstreams and proxy server UIs,
so users only need network access to the console port.

Workstream creation via MQ:
- POST /api/cluster/workstreams/new with three targeting modes:
  specific node (directed queue), auto (best node by capacity),
  or general pool (shared queue, any bridge picks up)
- Console pushes CreateWorkstreamMessage to Redis; bridge handles
  the rest (server creation, ownership registration, SSE events)

Reverse proxy for server UIs:
- /node/{node_id}/ serves the server's HTML with static path rewriting
  and a console-return banner injected after <body>
- JS proxy shim prepended to app.js overrides fetch() and EventSource()
  to route root-relative URLs through /node/{id}/api/...
- SSE streams proxied via httpx.AsyncClient(timeout=None) with per-
  connection clients for long-lived streams
- GET/POST API requests forwarded with body and auth token

Security:
- Proxy write paths checked against WRITE_PATHS to prevent read-token
  escalation (read tokens cannot POST /api/send through proxy)
- html.escape() on node_id in banner HTML to prevent XSS
- String length limits on name/model inputs

Frontend:
- "+ new" button in header opens creation modal with node dropdown
  (Auto / General pool / specific nodes with capacity display)
- Modal has focus trap, backdrop dismiss, scroll lock, keyboard handling
- Workstream rows and node links deep-link via proxy paths
- Custom select arrow, Instrument Panel modal styling

Documentation:
- docs/console.md rewritten with proxy and creation API docs
- docs/architecture.md console section updated
- PlantUML diagrams 01, 11, 12 updated + PNGs re-rendered
- README.md updated

28 new tests (741 total), ruff + mypy clean.

* Fix Copilot PR #14 review issues: auth bypass, XSS, proxy robustness

- Normalize trailing slashes in required_role() to prevent write-role
  bypass via /api/send/ or /node/{id}/api/send/ (auth.py)
- Validate node_id format in proxy handlers (alphanumeric, dot, dash,
  underscore only) to prevent injection vectors
- Use json.dumps() for JS proxy shim prefix to prevent script injection
- URL-quote node_id in HTML attribute contexts (proxy_index, proxy_static)
- Check upstream status in _proxy_sse() — emit error event on non-200
  instead of keeping a dead SSE connection open
- Check upstream status in proxy_index() — propagate non-2xx errors
- Forward query string in _proxy_post() (consistency with _proxy_get)
- Handle JSON null values in create_workstream() — treat null as empty,
  reject non-string types with 400
- Fix docs/diagram LPUSH → RPUSH to match actual broker implementation

* Add provider-native web search with Tavily fallback

Replace client-side Tavily web search with provider-native implementations:

- Anthropic: inject web_search_20250305 server-side tool, handle
  server_tool_use / web_search_tool_result streaming blocks, emit
  info_delta for search status display
- OpenAI: inject web_search_options for gpt-5-search-api, format
  url_citation annotations as footnote sources
- Local/vLLM: preserve existing Tavily-based web_search tool as fallback

Add supports_web_search to ModelCapabilities and info_delta to StreamChunk.
Remove end-of-life GPT-4o model entries from capability tables.
Update docs, diagrams, and README. 88 provider tests (32 new).

* Fix Copilot PR #13 review: capture streaming url_citation annotations

Accumulate url_citation annotations during OpenAI streaming and emit
formatted citations as a final info_delta chunk after the stream ends.
Previously annotations were only captured in non-streaming mode, so
search model users in the interactive path never saw citation sources.

Patrick Buckley d28879208f Add multi-provider LLM adapter with model capability flags (#12)
* Add multi-provider LLM adapter with model capability flags

Introduce a provider abstraction layer between ChatSession and LLM SDK
clients, enabling native support for Anthropic alongside OpenAI-compatible
APIs. Each provider translates at the API boundary while the internal
message format remains OpenAI-like throughout session history and persistence.

- LLMProvider protocol with StreamChunk/CompletionResult normalized types
- OpenAIProvider: GPT-4o, GPT-5.x, O-series capability tables with
  conditional temperature, reasoning_effort, and token param handling
- AnthropicProvider: native streaming, message/tool format conversion,
  adaptive vs manual thinking modes, effort parameter for 4.6 models
- ModelCapabilities per-model flags: temperature support, token param name,
  thinking mode, effort levels, context window, max output
- Smart auto-detect: latest Opus for Anthropic, latest base GPT for OpenAI
- --provider CLI flag for both turnstone and turnstone-server
- anthropic SDK as optional dependency (pip install turnstone[anthropic])
- 56 new provider tests, 672 total passing
- Updated architecture docs and 4 PlantUML diagrams

* Fix Copilot PR #12 review: reasoning_effort gating, Anthropic thinking, provider factory

- Default reasoning_effort_values to () so unknown/local models don't
  receive unsupported top-level reasoning_effort param. Models that need
  it (GPT-5.x, search models) have explicit capability declarations.
- Fix Anthropic _reasoning_params: "none" and "" effort now return {}
  instead of enabling thinking with 4096 budget.
- Use create_provider("openai") singleton instead of OpenAIProvider()
  in ChatSession fallback for consistency with registry path.
- Add 8 parameter gating tests: unknown model no reasoning_effort,
  GPT-5 no temperature, GPT-5.1 conditional temperature, O-series
  no temperature, Anthropic none/empty/low effort.

Patrick Buckley a1f00092f5 Migrate HTTP servers from stdlib to Starlette/ASGI + uvicorn (#11)
* Migrate HTTP servers from stdlib to Starlette/ASGI + uvicorn

Replace Python stdlib http.server (ThreadedHTTPServer, BaseHTTPRequestHandler)
with Starlette ASGI applications served by uvicorn across all three HTTP
entry points. SSE endpoints use sse-starlette EventSourceResponse with
async generators that bridge sync queue.Queue via run_in_executor().
Bridge SSE parser replaced with httpx-sse EventSource.

- turnstone/server.py: Starlette app factory with create_app(), pure ASGI
  middleware (auth, rate limit, metrics, CORS), async route handlers,
  lifespan context manager for startup/shutdown. WebUI and ChatSession
  remain fully synchronous — worker threads unchanged.
- turnstone/console/server.py: Same pattern, simpler (no ChatSession).
  Path params replace manual string slicing for node detail route.
- turnstone/mq/bridge.py: _iter_sse_data() uses httpx_sse.EventSource
  instead of hand-rolled line parser.
- Tests: All ThreadedHTTPServer fixtures replaced with
  starlette.testclient.TestClient via create_app() factories.
- Docs: Updated architecture.md, api-reference.md, README.md, and
  PlantUML diagrams (03, 11) + regenerated PNGs.

* Fix Copilot PR #11 review: TestClient cleanup, JSON error handling, SSE timeout

- Close TestClient in teardown for TestConsoleAuth and TestConsoleLogin to avoid lifespan/resource leaks
- Close TestClient via yield/finally in TestConsoleHTTPEndpoints fixture
- Add _read_json() helper for safe JSON body parsing (returns {} on invalid JSON instead of 500, matching old stdlib handler behavior)
- Apply same try/except pattern to console auth_login endpoint
- Increase SSE queue.get timeout from 1s to 5s to align with sse-starlette ping interval, reducing executor task churn

* Add operational features: health degradation, rate limiting, workstream eviction

Backend health monitor with circuit breaker (CLOSED/OPEN/HALF_OPEN) probes
LLM backend periodically; /health returns "degraded" when unreachable.
Token-bucket per-IP rate limiter with 429 + Retry-After responses;
/health and /metrics exempt. Workstream auto-eviction of oldest idle
when at configurable max_workstreams capacity.

New modules: healthcheck.py (BackendHealthMonitor, CircuitState),
ratelimit.py (TokenBucket, RateLimiter). 5 new Prometheus metrics.
Both UIs: health indicator, 429 retry with toast, eviction notifications,
node degradation badges (console), circuit state in dashboard footer.

Config: [health] and [ratelimit] TOML sections, max_workstreams in [server].
Docs: README, architecture, API reference, PlantUML diagrams updated.
616 tests pass (35 new), mypy clean, ruff clean.

* Fix Copilot PR #10 review: version import, capacity check order, validations, docs

- Use turnstone.__version__ instead of hard-coded "0.2.1" in /health and
  /metrics endpoints
- Move capacity check/eviction before session creation in
  WorkstreamManager.create() to avoid wasted work when at capacity
- Validate rate > 0 and burst >= 1 in RateLimiter when enabled
- Validate max_workstreams >= 1 in WorkstreamManager.__init__
- Parse do_POST path with urlparse for consistent rate limit exemptions
  and metrics labeling
- Fix should_allow_request docstring: HALF_OPEN allows requests through
  (not just one probe)
- Fix /health docstring: degraded when circuit is not CLOSED (includes
  HALF_OPEN)
- Add class="health-ok" to health indicator HTML to prevent visible
  empty pill before first poll
- Update PlantUML: remove stale MAX_WORKSTREAMS constant, fix

Patrick Buckley 2c48f694db Add multi-model support with ModelRegistry, fallback routing, and per… (#9)
* Add multi-model support with ModelRegistry, fallback routing, and per-workstream selection

Introduces a ModelRegistry that holds named model configurations loaded from
[models.*] sections in config.toml. Each workstream can select its model at
creation time or switch mid-session via /model <alias>. When the primary model
is unreachable, a configurable fallback chain tries alternative models. Sub-agents
(plan/task) can optionally use a cheaper model via the agent_model setting.

Core changes:
- New turnstone/core/model_registry.py: ModelConfig (frozen, api_key redacted from
  repr), ModelRegistry (thread-safe lazy client creation, resolve, fallback chain),
  load_model_registry() with backwards-compatible config loading
- session.py: registry/model_alias params, /model show+switch command, fallback in
  _create_stream_with_retry (extracted _try_stream), agent model override in _run_agent
- workstream.py: factory signature accepts optional model_alias, create() gains model param
- cli.py + server.py: build registry, updated session factories, banner, shutdown
- protocol.py: model field on CreateWorkstreamMessage
- bridge.py: pass model through workstream creation chain

Frontend:
- MODEL column added to dashboard tables in both server and console UIs
- Responsive: hidden alongside NODE at narrow viewports
- ARIA labels include model info, title attributes for truncated text
- SSE connected event includes model_alias

Documentation:
- README: architecture tree, Multi-Model Support section, config keys
- docs/architecture.md: module map, Multi-Model Registry subsection
- docs/api-reference.md: model field in workstream creation, model_alias in SSE
- PlantUML diagrams 02 + 03 updated with ModelRegistry

Tests: 43 new tests (576 total), mypy clean, ruff clean.

* Fix Copilot PR #9 review: model_alias property, preserve manual tool_truncation

- Expose model_alias as a public @property on ChatSession instead of
  accessing the private _model_alias from server.py and tests
- Track _manual_tool_truncation flag so /model switch only recomputes
  tool_truncation when it was auto-derived, preserving --tool-truncation
  overrides
- Update PlantUML diagram to reflect the public property

- session.py: mcp_client param, self._tools/_task_tools/_agent_tools,
  _prepare_mcp_tool/_exec_mcp_tool, /mcp introspection command
- tools.py: merge_mcp_tools() helper
- cli.py + server.py: --mcp-config arg, client lifecycle, banner info

Patrick Buckley b6c1c3a676 Add console-to-server deep linking via ?ws_id= query parameter (#7)
* Add console-to-server deep linking via ?ws_id= query parameter

Server UI parses ?ws_id= on load (both direct init and post-login) and
auto-selects the matching workstream instead of showing the dashboard.
URL is cleaned from the address bar via history.replaceState after
navigation. Defers initial SSE connection to avoid redundant connect
when deep-linking switches tabs immediately.

Console workstream rows are now clickable — opens the node's server UI
in a new tab with ?ws_id= targeting that workstream. Uses URL constructor
for safe URL building. External-link indicator (↗) appears on hover.
Rows without server_url have role/tabindex removed to avoid broken
affordance. currentServerUrl reset on showOverview() to prevent stale
fallback across views.

Collector injects server_url into workstream dicts in both the poll path
and ws_created event path so deep links work immediately.

* Fix Copilot PR #7 review: deep-link duplicate history entry, server_url test coverage

- Suppress history.pushState in switchTab() during deep-link navigation by
  setting _historyNavigation=true around both call sites (post-login and
  direct init). Fixes Back button appearing to do nothing on first press.
- Add server_url assertions to poll and ws_created collector tests to
  prevent regressions of deep-link functionality.
