 All notable changes to Switchboard Core are documented here.
 
+## v0.6.2 — Docs Polish + Dynamic OpenAPI
+
+Docs surface polish and dynamic OpenAPI spec with extension route merging.
+
+### Added
+
+- **Dynamic OpenAPI spec**: `GET /api/docs/openapi.json` builds a merged
+  spec at request time — kernel endpoints + auto-generated stubs for every
+  extension `api_routes` entry. Extensions may optionally declare `api_schema`
+  in `manifest.json` for richer path items (params, body, response examples).
+- **`api_schema` manifest field**: Optional array in `manifest.json`. Malformed
+  entries are logged and skipped — never blocks extension loading.
+- **Tests**: 7 new handler tests (zero extensions, stubs, rich schema,
+  multi-extension, malformed schema, disabled exclusion, required fields).
+
+### Fixed
+
+- **Dark mode contrast**: Replaced all hardcoded light-mode fallbacks in docs
+  CSS with theme-aware CSS variables. Tables, code blocks, nav items, and
+  headings now readable in dark mode.
+- **Docs loading state**: Replaced borrowed `settings-placeholder` animation
+  with docs-specific pulse skeleton. Added error state with retry button.
+- **Docs routing**: Default route (`/docs`) now redirects to
+  `/docs/GETTING-STARTED` instead of the blank `/:section` placeholder.
+- **Docs scrolling**: Content area now scrolls correctly — full document
+  visible without text overflowing viewport.
+- **Docs icon**: Changed from 🧩 to 📖 in the user menu.
+- **Docs duplicate menu entry**: Docs was appearing twice (once from surfaces
+  API, once from hardcoded items). Added `'docs'` to `CORE_IDS` filter.
+- **Swagger UI**: Updated to point at dynamic `/api/docs/openapi.json`
+  endpoint. Static YAML preserved for backward compatibility.
+- **OpenAPI tests on Postgres**: `openapiTestStores()` was hardcoded to
+  `sqlite.NewStores()` — caused `pq: syntax error at or near ","` in CI.
+  Now uses `database.IsSQLite()` check like all other handler tests.

 # Switchboard Core — Roadmap
 
-## Current: v0.5.3 — Chat Polish + Integration Testing
+## Current: v0.6.2 — Docs Polish + Dynamic OpenAPI
 
-Fork of chat-switchboard, gutted to a pure extension platform. All AI/chat
-features removed from the kernel. What remains is the minimum viable
-platform that extensions build on.
+Self-hosted extensible platform. Auth, identity, packages, Starlark sandbox,
+storage, realtime, and ops are kernel primitives. Everything else is an extension.
 
-### Retained kernel capabilities
+**Kernel capabilities:** Auth (builtin/mTLS/OIDC) · Users/teams/groups/RBAC ·
+Surfaces/extensions/libraries/workflows · Starlark sandbox (capability-gated) ·
+Object storage (PVC/S3) + ext_data tables · WebSocket hub + realtime pub/sub ·
+Audit log · Notifications · Scheduled tasks
 
-- **Auth**: builtin (simple), mTLS, OIDC
-- **Identity**: users, teams, groups, permissions (RBAC)
-- **Packages**: surfaces, extensions, libraries, workflows
-- **Starlark sandbox**: capability-gated modules
-- **Storage**: object storage (PVC, S3), ext_data tables
-- **Realtime**: WebSocket hub, presence, multi-replica HA
-- **Ops**: audit log, notifications, maintenance goroutine
+**Completed history:** v0.2.x–v0.5.x fully documented in `CHANGELOG.md`.
+Highlights: RBAC + settings cascade, event bus + triggers, SDK stabilization,
+workflow engine (multi-stage, team roles, signoff gate, public entry, SLA),
+package distribution, Notes surface (CM6, folders, tags, backlinks, graph),
+realtime primitive, Chat surface (chat-core library + surface + polish),
+upgrade test harness, cluster registry + HA.

-
-## v0.2.x — SDK & Triggers
-
-The contract that extensions build against. Three trigger primitives,
-SDK stabilization, and the first rebuilt extension (tasks).
-
-### v0.2.0 — RBAC + Settings Cascade (complete)
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Admin → RBAC group | ✅ | `surface.admin.access` permission + Admins system group replaces `role == "admin"` checks. Admin bypass removed from permission middleware. |
-| Settings cascade | ✅ | `user_overridable` flag, three-tier resolution (global → team → user), team settings API |
-| ~~Settings override model~~ | ✅ | Shipped with settings cascade above |
-
-### v0.2.1 — Default Surface + ICD
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Default surface routing | ✅ | `/` redirects to configurable default surface. No surfaces → admin. First install becomes default. Changeable in admin settings. |
-| ICD (API contract) | ✅ | Full OpenAPI 3.0.3 spec — 160 operations, 22 tag groups, reusable component schemas. Served at `/api/docs`. |
-
-### v0.2.2 — Event Bus + Triggers
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Event bus subscriptions | ✅ | Extensions register event patterns in manifest. Wired via `bus.Subscribe()` on startup. Async handler invocation. |
-| Webhook triggers | ✅ | Inbound HTTP at `/api/v1/hooks/:package_id/:slug`. HMAC-SHA256 verification. Synchronous Starlark handler response. |
-| Scheduled tasks | ✅ | User-created cron tasks with restricted sandbox (no raw HTTP, no DB table creation). Runs as creator identity. Templates from extensions. Dedicated schedules API. |
-| Trigger admin API | ✅ | CRUD for triggers + schedules. Enable/disable, execution logs, per-package listing. |

-
-### v0.2.4 — Shell Navigation + Schedules
-
-| Step | Status | Description |
-|------|--------|-------------|
-| SDK Topbar | ✅ | `sw.shell.Topbar` — composable navigation bar (title + extension slot + bell + user menu). Surfaces get consistent nav for free. |
-| Schedules surface | ✅ | New `packages/schedules/` wrapping kernel cron API. Table view, cron preview, enable/disable, manual run, execution logs. |
-| Manifest icons | ✅ | `icon` field in manifest.json (emoji). Surfaces API returns icon. UserMenu renders per-surface icons. |
-| UserMenu cleanup | ✅ | Removed dead Chat/Notes/Projects links. Menu driven by surfaces API. Core surfaces filtered. |

-
-| Step | Status | Description |
-|------|--------|-------------|
-| UI bug pass | ✅ | Reviewed admin, settings, login, welcome surfaces in light/dark themes. Fixed settings crash (models API undefined). Removed dead chat settings from both user and admin settings. |
-| Dead code sweep | ✅ | Removed ~700 lines: orphaned CSS, dead Go types, stale event code, unused test helpers, dead settings UI (chat defaults, system prompt, default model, policies, web search, compaction, memory). |
-| Template cleanup | ✅ | Removed stale CSS link tags and orphaned chat-pane.html. Updated doc comments throughout. |
-| Package proof-of-concept status | ✅ | Created README.md for tasks + schedules with graduation criteria. Added missing manifest icons. |
-| Welcome surface | ✅ | New fallback surface when no extensions installed. Topbar + welcome card with admin link. Replaces `/admin` as final redirect target. |
-| Default surface routing | ✅ | Resolution chain: user preference → global config → first extension → `/welcome`. Users can set personal default in Settings > General. Admin sets global default in Admin > Settings. |
-| Admin navigation | ✅ | Replaced Back button with UserMenu in admin topbar. Eliminates back-button infinite loop. |
-
-### v0.2.6 — Admin Settings Audit
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Admin settings E2E | ✅ | All 7 admin settings sections verified (default surface, registration, banner, message bar, footer, vault, email). Dead code removed: `sectionCategory()` pruned of AI/routing/channel vestiges, `PublicSettings()` stripped of chat-era fields (system_prompt, retention_ttl, paste_to_file, allow_user_personas), dead `PolicyDefaults` removed (allow_raw_model_access, default_model), dead policy lookups removed (kb_direct_access), test seed data cleaned. |
-| Packages surface | ✅ | Package list loads (17 total/17 enabled), type filters work, enable/disable visible, settings/export buttons present, core package (admin) protected. Removed dead `chat` from CORE_IDS. |
-

-
-| Step | Status | Description |
-|------|--------|-------------|
-| User settings E2E | ✅ | All 6 user settings sections verified (General, Appearance, Profile, Teams, Connections, Notifications). Dead code removed: BYOK nav section + state, personas gate filter, Message Font Size slider, `auth.permissions.changed` listener. localStorage key renamed `cs-appearance` → `sb-appearance` with one-time migration. |
-| Visibility gating | ✅ | Dead BYOK/personas policy lookups removed from bootstrap and permissions handlers. `allow_user_byok` removed from `PublicSettings`. `PolicyDefaults` cleaned of `allow_user_byok` and `allow_user_personas`. Dead `msgFont` early-apply removed from base template. Stale policy-gating test assertions replaced. No empty nav sections remain. |
-
-### v0.2.8 — Team Admin Settings Audit (Pass 1)
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Team admin E2E | ✅ | Audited team member management, settings cascade, role assignment. Removed dead code: `HasPrivateProviderRequirement` (BYOK vestige), `UserRole` on `TeamMember` (deprecated role column), `allow_team_providers` policy default, dead personas/providers/models ICD tests. |
-| Workflow stage UI cleanup | ✅ | Removed dead personas dropdown, `history_mode` selector, stale `chat_only` mode. Updated `STAGE_MODES` to match backend CHECK constraint (`form_only`, `form_chat`, `review`, `custom`). Removed stale comments referencing deleted files. |
-
-### v0.2.9 — Builtin Extension Retirement
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Retire builtin seeder | ✅ | Removed `SeedBuiltinPackages`, `seed_packages.go`, Dockerfile COPY, and `extensions/builtin/` directory. These extensions are dormant until a chat surface exists to consume them. |
-| Convert to regular packages | ✅ | Repackaged 6 extensions as standard directories in `packages/` with `js/` layout and `"requires": ["chat"]` manifest metadata. Built via `build.sh` like all other packages. No auto-install — explicit install only. |
-
-## v0.3.x — Workflow Architecture
-
-Workflows are the core platform capability. This series implements the
-full multi-step automation system with team role integration and
-finalizes the extension lifecycle model.
-
-### v0.3.0 — Schema Redesign + Stage CRUD Modernization (complete)
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Workflow schema redesign | ✅ | Dropped `persona_id`, `history_mode` from `workflow_stages`. Renamed `transition_rules` → `stage_config`. Updated `stage_mode` CHECK to `(form, review, delegated, automated)`. Added `audience`, `stage_type`, `starlark_hook`, `branch_rules`. Both PG + SQLite. |
-| Model + store updates | ✅ | Go structs, constants, and PG/SQLite queries updated. New `ValidStageTypes`, `ValidAudiences` maps. Routing engine reads `branch_rules` directly. |
-| Handler + Starlark updates | ✅ | Stage CRUD validation for new fields. Package export/import updated. Hook handler reads `stage_config`. Starlark module exposes `audience`, `stage_type`. |
-| Frontend updates | ✅ | Team-admin and admin stage editors updated with new modes, audience selector, stage type selector, conditional Starlark hook input. Fixed admin `STAGE_MODES` bug. |
-
-### v0.3.1 — Instance + Assignment Tables + Store (complete)

-| Assignment schema | ✅ | `workflow_assignments` table. Per-stage queue: instance_id, stage, team_id, assigned_to, status, review_data. Optimistic claim lock. |
-| Models + store interface | ✅ | `WorkflowInstance`, `WorkflowAssignment` structs. 15 store methods for instance lifecycle and assignments across PG + SQLite. |
-| Event types | ✅ | `workflow.started`, `workflow.cancelled`, `workflow.error` added to bus route table. |
-
-### v0.3.2 — Workflow Engine + Handlers (complete)
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Store tests | ✅ | Round-trip tests for all 15 v0.3.1 store methods (instance + assignment CRUD). TruncateAll updated for new tables. |

-| Instance handlers | ✅ | HTTP API: Start, GetInstance, Advance, Cancel, ListInstances. Team-scoped mirrors. |
-| Assignment handlers | ✅ | HTTP API: Claim, Unclaim, Complete, Cancel, ListByTeam, ListMine. Claimer identity verification. |
-| Starlark module expansion | ✅ | `workflow.get_instance()`, `workflow.list_instances()` (read-only). Mutating builtins deferred pending interface extraction. |
-
-### v0.3.3 — Public Entry + Background Jobs (complete)
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Public entry | ✅ | `StartPublic`, `ResumePublic`, `AdvancePublic` — token-based anonymous workflow participation. Public routes at `/api/v1/public/workflows/`. Audience-gated: only `public` stages can be advanced anonymously. |
-| SLA scanner | ✅ | Background goroutine (5-min interval) checking active instances against per-stage `sla_seconds`. Fires `workflow.sla_breach` event, marks breach in instance metadata (idempotent). |
-| Staleness sweep | ✅ | Per-workflow `staleness_timeout_hours` column. Scanner marks idle instances as `stale`, cancels open assignments, fires `workflow.stale` event. |
-
-### v0.3.4 — Team Roles + Multi-party Validation (complete)
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Team roles | ✅ | Removed CHECK constraint on `team_members.role`. Custom roles stored in `teams.settings["roles"]`. Team roles API (`GET/PUT /teams/:teamId/roles`). Role-based stage assignment via `stage_config.required_role`. Frontend: dynamic role selects, role management panel. |
-| Multi-party sign-off | ✅ | `workflow_signoffs` table (both dialects). `StageConfig.validation` with `required_approvals`, `required_role`, `reject_action`. Engine validation gate in `advanceInternal`. `SubmitSignoff` engine method. Signoff HTTP API (`POST/GET /instances/:iid/signoffs`). Frontend signoff panel in monitor tab. |
-| Extension lifecycle | ✅ | Design doc: `docs/DESIGN-EXTENSION-LIFECYCLE.md`. Permanent vs PoC classification, graduation criteria, install model. |
-| Trigger composition | ✅ | Design doc: `docs/DESIGN-TRIGGER-COMPOSITION.md`. Triggers/schedules can start workflows, workflows emit events, no circular invocation. |

-### v0.3.5 — Settings Audit + ICD + Tests
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Clone endpoint | ✅ | `POST /api/v1/workflows/:id/clone` — deep copy workflow + stages. Handler-level composition of existing store methods. |
-| Integration tests | ✅ | 7 engine-level tests in `workflow_engine_test.go`: full lifecycle, branch routing, public entry, signoff gate, rejection, cancel-clears-assignments, error cases. 28 total tests. |
-| Settings audit pass 2 | ✅ | Added `staleness_timeout_hours` field to workflow editor. Added collapsible branch_rules JSON editor in stage form. |
-| ICD update | ✅ | Fixed stale Workflow/Stage schemas. Added WorkflowInstance, WorkflowAssignment, WorkflowSignoff schemas. Added ~20 new endpoints: instances, assignments, signoffs, public entry, clone, team roles. |
-
-### v0.3.6 — Example Workflows + Interactive Demo
-
-Four installable `.pkg` workflow packages that prove the engine works
-end-to-end, plus a demo surface for guided exploration.

-| Webhook Notifier | ✅ | Starlark `http.post` + `connections.get` for outbound webhooks, delivery logging to ext_data. Proves HTTP + connections modules. |
-| Demo surface | ✅ | Browser-tier walkthrough: workflow cards, stage diagrams, Starlark viewer, "Try It" buttons, API curl examples. Auto-installed, removable. |
-| Engine context fix | ✅ | Add `started_by` to automated stage Starlark context dict (backward-compatible). |
-| SLA package installer | ✅ | Added `sla_seconds` support to `workflowPkgStage` struct and install/export paths. |
-| Snapshot format fix | ✅ | `parseSnapshotStages` helper handles both wrapped and legacy snapshot formats. |
-| Workflow adoption | ✅ | `POST /teams/:teamId/workflows/:id/adopt` + `GET .../available`. Team-admin "Adopt Global" button. `TeamID` in `WorkflowPatch`. |

-| Documentation | ✅ | `docs/DEMO-WORKFLOWS.md`: feature capability matrix, stage flows, API walkthrough, per-package READMEs. |
-| Review pass | | Docker E2E walkthrough: install all packages, adopt into team, activate, publish, run each workflow end-to-end. Fix remaining UI/UX issues. |
-
-### v0.3.7 — Package Audit (complete)
-
-Verified all 16 packages install correctly. Packages with unmet `requires` auto-set to dormant.
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Manifest fixes | ✅ | Fixed 6 chat-extension manifests (`"name"` → `"title"`, was blocking install). Added explicit `"type": "surface"` to hello-dashboard, icd-test-runner, sdk-test-runner. |
-| Dormant status | ✅ | Added `dormant` to `packages.status` CHECK constraint (both dialects). Installer auto-detects unmet `requires` and sets `status=dormant, enabled=false`. Enable endpoint returns 409 for dormant packages. |
-| Functional audit | ✅ | Navigated to every surface in browser. 7 working: schedules, tasks, team-activity-log, git-board, hello-dashboard, icd-test-runner, sdk-test-runner. 2 broken: dashboard + editor (depend on removed `sw.*` imperative SDK) — tagged `requires: ["legacy-sdk"]` → dormant. |
-| Chat-dependency tagging | ✅ | 6 chat-dependent extensions (csv-table, diff-viewer, js-sandbox, katex-renderer, mermaid-renderer, regex-tester) install as dormant. git-board and gitea-client are standalone. |
-| Dependency check fix | ✅ | Relaxed library dependency validation to allow `pending_review` libraries (gitea-client declares permissions). Only `suspended`/`dormant` libraries blocked. |
-| Admin UI | ✅ | Dormant badge, disabled Enable button with tooltip, Dormant stat card in admin packages view. |
-| Tests | ✅ | 4 handler tests (SetStatus dormant, enable blocked, surfaces exclude dormant, admin list includes dormant). All existing tests pass. |
-

-Builder image for faster builds, bundled packages for zero-config first run.
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Builder image | ✅ | `Dockerfile.builder` with cached Go modules + Node vendor libs for faster custom builds. |
-| Bundled packages | ✅ | Dockerfile stage builds all 12 non-dormant packages into production image. `InstallBundledPackages` auto-installs on first run (skip-if-present). `SKIP_BUNDLED_PACKAGES=true` to disable. `BUNDLED_PACKAGES` allowlist for selective install (Helm/K8s). Migration 012 adds `bundled` source to CHECK constraint. |
-| Distribution docs | ✅ | `docs/DISTRIBUTION.md` — quick start, bundled packages, builder image, custom builds, production deployment. |
-| Tests | ✅ | 6 handler tests (fresh install, skip existing, missing dir, empty dir, dormant handling, allowlist filtering). All existing tests pass. |
-
-## v0.4.x — Notes Surface

-| Wikilink extraction | ✅ | `_extract_wikilinks()` parses `[[...]]` using `split("[[")` + `find("]]")` (no regex/while in Starlark). Deduplicates by lowercase. |
-| Link sync on save | ✅ | `_sync_links()` called from `_create_note` and `_update_note`. Delete-all + reinsert pattern (matches tags). Resolves titles to note IDs (case-insensitive). Unresolved links stored with `target_id=""`. |
-| Cascade delete | ✅ | Hard-deleting a note removes both outgoing links (source_id) and incoming backlinks (target_id). |
-| Link endpoints | ✅ | `GET /links/:note_id` (outgoing) and `GET /backlinks/:note_id` (incoming, enriched with source titles). |
-| Wikilink preview | ✅ | `[[Note Title]]` rendered as clickable accent-colored links in markdown preview. Unresolved links styled in danger/red. |
-| Wikilink navigation | ✅ | Clicking a resolved wikilink navigates to the target note. Clicking an unresolved (red) link creates the note, navigates to it, and re-saves the source so the link resolves. |
-| Backlinks panel | ✅ | Collapsible panel below editor showing all notes linking to current note. Click to navigate. Hidden when empty. |
-| Stats update | ✅ | `/stats` includes `links` count. Notes package version bumped to 0.4.0. |

-| Default-rendered mode | ✅ | Preview is the initial state on note open. "Edit" button enters CM6. Tri-state `viewMode`: `rendered` / `edit` / `split`. |
-| Split view | ✅ | Side-by-side layout: CM6 left, rendered preview right. CSS grid two-column in `.notes-editor__body--split`. |
-| Synced scroll | ✅ | Split mode scroll sync. CM6 `scrollDOM` scroll listener maps position ratio to preview `scrollTop`. Linear mapping. |
-| View mode setting | ✅ | `editor_mode` in manifest settings + localStorage persistence. Toolbar cycles rendered → edit → split. |
-| Document outline | ✅ | `parseHeadings()` extracts headings (skips code blocks). Collapsible `DocumentOutline` panel with click-to-scroll (CM6 line dispatch or preview `scrollIntoView`). Debounced 300ms updates. |
-
-### v0.4.6 — Sidebar Restructure (complete)
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Sidebar tabs | ✅ | Two-tab header at top of sidebar: "Notes" (folders → tags → search → list) and "Outline" (heading tree for active note). Outline tab enabled only when a note is selected. |
-| Heading tree | ✅ | Nested heading hierarchy (H1 → H2 → H3) with depth indentation. Click → scroll to heading in editor/preview. Current heading highlighted based on scroll position. |
-
-### v0.4.7 — Note Graph
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Graph API | ✅ | `GET /graph` endpoint in Starlark — `{ nodes: [{id, title, folder_id, tags}], edges: [{source, target, text}] }`. Full notes + links in one payload. |
-| Graph renderer | ✅ | Canvas force-directed layout. Minimal force simulation (repulsion + attraction + damping). Nodes = circles with title labels, edges = lines. Zoom/pan via wheel + drag. Retina-aware rendering. |
-| Click → focus + filter | ✅ | Single click a node: dims unconnected nodes/edges to 15% opacity. Clicked node + direct neighbors stay full brightness. Edges highlighted in accent color. Click empty space to reset. |
-| Shift+click → chain | ✅ | Shift+click adds a second node to the focus set — union of both neighborhoods visible. Trace thought paths across two hops without losing context. |
-| Double-click → open | ✅ | Double-click navigates to the note and exits graph view, opening the editor with the selected note. |
-| Hover → tooltip | ✅ | Hover shows note title + tag pills + edge count in HTML overlay. No API call — all data in graph payload. |
-| Folder/tag coloring | ✅ | Nodes colored by folder using 10-color palette. Active tag filter dims non-matching nodes to 30% opacity. Stacks with click focus. |
-| Orphan highlighting | ✅ | Zero-edge nodes rendered with dashed stroke. "Hide orphans" checkbox toggle in toolbar. |
-| Entry point | ✅ | "Graph" button in topbar. Replaces editor pane with full graph canvas. Single-click selects note in sidebar; double-click opens editor. |
-
-## v0.5.x — Realtime + Chat
-
-Communication primitive track. The kernel gains one generic realtime
-module. Everything else — conversations, messages, participants — is
-pure extension code. Human-to-human chat ships pre-MVP; LLM
-participation is post-MVP.
-
-### v0.5.0 — Realtime Primitive + Dialog Audit + Permissions UI
-
-| Step | Status | Description |
-|------|--------|-------------|
-| `realtime.publish()` | ✅ | Starlark module: `realtime.publish(channel, event, data)`. Publishes JSON event to WebSocket hub scoped to channel. Gated by `realtime.publish` permission. 7KB payload limit. Reserved prefix validation. |
-| WS room protocol | ✅ | `room.subscribe` / `room.unsubscribe` client messages intercepted in readPump. Per-connection 100-room cap. |
-| `sw.realtime.subscribe()` | ✅ | SDK method: `sw.realtime.subscribe(channel, [event], callback)`. Auto room join/leave, reconnect recovery. Returns unsubscribe handle. |
-| `sw.ui.Dialog` | ✅ | Pre-existing (implemented before v0.5.0). SDK modal primitive with focus trap, Promise-based API. |
-| `sw.ui.Confirm` / `sw.ui.Prompt` | ✅ | Pre-existing. `sw.confirm()` and `sw.prompt()` already exposed in SDK. |
-| Native dialog audit | ✅ | 5 bare `confirm()` calls migrated to `sw.confirm()` in tasks, schedules, notes (×2), editor packages. |
-| Admin permissions UI | ✅ | Permissions drawer in admin Packages page. Grant/revoke per permission, grant-all bulk action. `pending_review`/`suspended` status badges. SDK API client methods added. Closes gap identified in v0.4.7. |
-
-### v0.5.1 — Chat Core Library
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Library package | ✅ | `chat-core` library with `permissions: ["db.write", "realtime.publish"]`. Private ext_data tables, exported Starlark functions, REST endpoints. |
-| Conversations table | ✅ | `conversations` — title, type (direct/group), created_by, updated_at. |
-| Participants table | ✅ | `participants` — conversation_id, participant_id, participant_type (user/bot), display_name, role (member/admin), joined_at. |
-| Messages table | ✅ | `messages` — conversation_id, participant_id, content, content_type (text/system/file), edited_at. |
-| Read cursors table | ✅ | `read_cursors` — conversation_id, participant_id, last_read_message_id. |
-| Exported Starlark API | ✅ | `create()`, `send()`, `history()`, `add_participant()`, `remove_participant()`, `mark_read()` — available via `lib.require("chat-core")`. |
-| REST endpoints | ✅ | 15 routes: full CRUD for conversations, messages, participants. Cursor-based paginated message history. Per-conversation unread counts. |
-| Realtime integration | ✅ | On `send()`: insert message, publish `realtime.publish("conversation:{id}", "message", data)`. Also emits `participant.added`, `participant.removed`, `message.edited`, `message.deleted` events. |
-| db.query() range params | ✅ | Kernel enhancement: `before`/`after` kwargs for `db.query()` enabling cursor-based pagination and efficient unread counting. 7 new tests. |
-| Admin Library filter | ✅ | Added `Library` type filter to admin Packages page alongside Surface/Extension/Full/Workflow. |
-| Admin filter Dropdown | ✅ | Replaced button group with themed `Dropdown` primitive for type filter. Keyboard nav, consistent theming via CSS vars. |
-| Unicode security gate | ✅ | `ScanSource()` detects variation selectors, bidi overrides, zero-width chars, tag characters. `Verdict()` blocks GlassWorm payloads and Trojan Source (CVE-2021-42574). Two enforcement points: install (422) + Starlark exec. 23 new tests. |
-
-### v0.5.2 — Chat Surface
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Conversation list | done | Sidebar: conversation list with last message preview, unread badge, timestamp. Create conversation button. |
-| Message thread | done | Main pane: message history with participant avatars, timestamps, content. Scroll-to-load-more for long threads. |
-| Compose bar | done | Text input with Enter-to-send, Shift+Enter for newline. Auto-resize textarea. |
-| Participant sidebar | done | Collapsible right panel: participant list with online status (via kernel presence hub). Add/remove participants using `sw.ui.Dialog`. |
-| 1:1 and group | done | Direct messages (two participants) and group conversations. Type field on conversation. |
-| Typing indicators | done | `realtime.publish("conversation:{id}", "typing", {participant_id})` on keypress with debounce. Surface shows "X is typing…" with auto-expire. |
-| Read receipts | done | Mark-read on scroll/focus via `chat.mark_read()`. Unread count in conversation list. |
-| Message editing | done | Edit own messages. `edited_at` timestamp displayed. Edit via `PUT /messages/:id`. |
-| Message deletion | done | Soft-delete own messages. Replaced with "message deleted" placeholder. |
-
-### v0.5.3 — Chat Polish + Integration Testing
-
-| Step | Status | Description |
-|------|--------|-------------|
-| `db.query()` search_like | ✅ | Kernel enhancement: `search_like` kwarg on `db.query()` — generates OR-joined `LIKE` (SQLite) / `ILIKE` (Postgres) clauses. Reusable by any package. 5 new tests. |
-| Conversation search | ✅ | `GET /search?q=term` endpoint in chat-core. Searches conversation titles and message content across user's conversations. Debounced search UI in sidebar with conversation + message results. |
-| Message pagination polish | ✅ | Scroll position preservation on load-more (records `scrollHeight`, restores via `requestAnimationFrame`). Loading spinner at top during fetch. `has_more` button hidden while loading. |
-| Multi-user E2E | ✅ | `docker-compose-e2e.yml`: 2 replicas + Postgres + nginx LB. `ci/e2e-chat-test.sh`: auth, create, send, cross-replica read, search, pagination. `ci/e2e-ws-listener.js` for realtime event testing. |
-| Workflow integration | ✅ | `workflow-chat` library package: `on_advance` hook creates scoped group conversation, adds team members, sends system message, enriches `stage_data` with `conversation_id`. Idempotent. 6 new hook tests. |
-
-### Backlog — Admin UI Polish
-
-| Item | Description |
-|------|-------------|
-| "Requires Review" filter | Dropdown filter option or dedicated button for `pending_review` packages. Useful when the package list grows long. |
-| Extreme UI scale polish | At 150%+ scale: user menu items overflow viewport (need scroll), topbar elements clipped. Ensure all surfaces and menus are usable at scale extremes (80%–200%). |
-
-### v0.5.4 — Package Updates
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Curate bundled packages | ✅ | Default set reduced from 23 to 8 core packages. `BUNDLED_PACKAGES=*` for all; explicit list for custom. |
-| Version comparison | ✅ | Semver parsing (`ParseSemver`) with prerelease support. Version bump validated on update. |
-| Schema migration on update | ✅ | `MigrateExtTables` diffs `db_tables` against existing schema. Adds new columns/tables. No destructive changes. |
-| Data preservation | ✅ | ext_data tables survive update. Settings merged (new keys added with defaults, existing preserved). |
-| Update API | ✅ | `POST /api/v1/admin/packages/:id/update` — accepts `.pkg` archive, validates version bump, applies schema diff, replaces code. |
-| Admin UI | ✅ | Update button on non-core package cards. Confirm dialog before upload. |
-| Export API | ✅ | `GET /api/v1/admin/packages/:id/export` — streams installed package as .pkg ZIP. Manual rollback: export → update → re-install old .pkg if needed. |
-
-### v0.5.5 — Upgrade Testing
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Test harness | ✅ | `docker-compose-upgrade.yml` + `ci/e2e-upgrade-test.sh`: build v(old) image, seed notes/conversations/settings, upgrade to v(new), verify data integrity. |
-| Schema edge cases | ✅ | 11 Go unit tests: add column (idempotent), add table, add index, multi-column add, row preservation across migration. All pass on SQLite. |
-| Settings migration | ✅ | Go tests verify: global/team/user overrides preserved across package update, new keys get defaults, removed keys not deleted from DB. |
-| Package compatibility | ✅ | Go tests verify: bundled skip-if-present on restart, dormant status for unmet requires, enabled/type preserved across version bump. |
-| Multi-replica upgrade | ✅ | `ci/e2e-upgrade-rolling.sh`: rolling upgrade with 2 replicas + shared Postgres, cross-replica reads during mixed-version window, pg_notify fan-out verified. |

+## v0.6.x — Pre-Fork Hardening
+
+Closes every audit finding before the public fork. No new features — only correctness, dead code elimination, and architectural cleanup. Sequence is fixed: each version is a gate for the next.
+
+### v0.6.3 — Dead Code Sweep + Registry Fix
+
+Pure cleanup. No behavior changes except fixing the broken registry install flow.
+
+| Step | Status | Description |
+|------|--------|-------------|
+| Fix registry install | ☐ | SDK sends `{ url }`, handler expects `{ download_url }`. Fix `api-domains.js` to send `{ download_url: url }`. Every Install click currently returns 400. |
+| Registry settings UI | ☐ | Add "Package Registry" section to admin settings with URL input field. Only way to configure registry today is a raw `PUT /api/v1/admin/settings/package_registry` — no user will find it. |
+| Registry tooling + docs | ☐ | `scripts/generate-registry.sh` scans a directory of `.pkg` files and emits registry JSON. `docs/PACKAGE-REGISTRY.md` documents the format. |
+| Delete dead kernel Go | ☐ | `store/interfaces.go:178–183` — orphaned ChannelListFilter comments. `pages/pages.go:922–930` — `roleFilterType()` + template registration (chat vestige, maps nonexistent roles). `main.go:67` — orphaned provider-type comment. |
+| Delete dead vendor JS | ☐ | `vendor/marked.min.js` and `vendor/purify.min.js` — 62KB, zero production imports. Only referenced in test helpers. |
+| Delete `dev.html` | ☐ | 676 lines, not imported by anything. Dead. |
+| Remove `dashboard` from default bundle | ☐ | Requires `legacy-sdk` (doesn't exist), auto-installs as dormant on fresh installs. Confusing. Remove from `defaultBundledPackages`. |
+| Remove `hello-dashboard` | ☐ | Proof-of-concept from early development. Move to `examples/` or delete. |
+| Strip stale version comments | ☐ | 60+ files have `// v0.29.x:`, `// v0.33.x:` pre-fork comments. Single sed pass. |
+| Narrow default bundle | ☐ | Default: `notes`, `chat`, `chat-core`, `mermaid-renderer`, `schedules`. Everything else available via registry or `BUNDLED_PACKAGES=*`. |
+
+### v0.6.4 — Admin Health/Metrics Tab + Cluster Merge
+
+Structural move: cluster dashboard becomes an Admin tab. Better home for health/metrics — shared context with other admin panels, no separate nav entry.
+
+| Step | Status | Description |
+|------|--------|-------------|
+| "Health / Metrics" admin tab | ☐ | New tab in Admin surface. DB-agnostic metrics for all deployments. Cluster cards conditional on PG + multi-node detection. |
+| Runtime metrics | ☐ | Per-node: goroutines, heap alloc/sys, stack in use, GC cycles, last GC pause, GC CPU %, uptime, WebSocket clients, extensions loaded, open FDs. |
+| DB pool metrics | ☐ | All deployments: DB latency (`SELECT 1` round-trip), pool active/idle/max, wait count, wait duration. PG-only: table bloat (`n_dead_tup`), active backends (`pg_stat_activity`). |
+| Cluster metrics | ☐ | PG multi-node only: cluster size, peer list with endpoint + uptime, heartbeat age per node, event bus publish/deliver rates. |
+| Extension runtime metrics | ☐ | Starlark exec/min, errors/min, avg duration, HTTP outbound requests/min, trigger fires/min, schedule overruns. |
+| Fatten heartbeat payload | ☐ | Heartbeat JSONB carries full metric set. `GET /api/v1/admin/metrics` for single-node SQLite fallback (same shape). |
+| Retire `cluster-dashboard` | ☐ | Remove package once Admin Health tab ships. Update `defaultBundledPackages`. |
+| Fix block renderer `requires` | ☐ | `mermaid-renderer`, `katex-renderer`, `csv-table`, `diff-viewer` all have `"requires": ["chat"]`. These are content renderers, not chat features. Remove constraint — they should activate without chat. |
+| Health endpoint consolidation | ☐ | `/health` and `/api/v1/health` return near-identical JSON. Merge or clearly differentiate with docs. |
+
+### v0.6.5 — Renderer Pipeline + Docs Rewrite
+
+Most complex sub-version. Lifts block rendering to a kernel SDK primitive so all surfaces share it, then rewrites the docs for an external audience.
+
+| Step | Status | Description |
+|------|--------|-------------|
+| SDK renderer primitive | ☐ | `sw.renderers.register(pattern, handler)` — kernel-level registration. Extensions call once; all surfaces consume. Decouples renderer discovery from chat surface. |
+| Notes hooks SDK renderer pipeline | ☐ | Notes `renderMarkdown()` delegates fenced blocks to registered renderers instead of emitting raw `<pre>`. |
+| Docs hooks SDK renderer pipeline | ☐ | Docs markdown renderer delegates fenced blocks to registered renderers. |
+| Unify markdown renderer | ☐ | Three separate markdown implementations (Notes hand-rolled, Docs hand-rolled, Chat `marked`). Adopt `marked` (already vendored) across all three surfaces. Delete hand-rolled duplicates. |
+| Sanitize HTML output | ☐ | DOMPurify is vendored but unused. Wire it as post-render step for user-generated markdown (Notes). Closes XSS surface. |
+| Mermaid/KaTeX/CSV/Diff work everywhere | ☐ | With `requires: ["chat"]` removed (v0.6.4) and renderer pipeline lifted, these render in notes + docs + chat without surface-specific code. |
+| Docs rewrite for external audience | ☐ | Remove all references to "chat-switchboard", "the fork", "the gut", "Phase 0", "scorched earth". Reframe from "we removed X" to "the kernel provides Y". Remove pre-v0.2.0 version references. |
+| Add Mermaid architecture diagrams | ☐ | Diagrams in docs: system architecture overview, request flow, extension lifecycle, realtime event flow, settings cascade, cluster topology. Serves double duty: good docs + proof mermaid-renderer works in docs surface. |
+| Surface alias decision | ☐ | `main.go:819–826` has six `/admin/surfaces/*` alias routes. Decision: keep permanently (document) or migrate SDK + ICD runner to `/admin/packages/` and delete. Ship one or the other, not both undocumented. |
+| `CONTRIBUTING.md` + tutorial | ☐ | "Build your first extension" guide: manifest → Starlark → ext_data → API route → surface JS → install → test. Use `team-activity-log` as worked example. |
+
+### v0.6.6 — Pre-Fork Hardening
+
+Final pass before the hard fork. Security, correctness, and developer experience.
+
+| Step | Status | Description |
+|------|--------|-------------|
+| Extension dependency auto-activation | ☐ | Installing a package with unmet `depends`/`requires` should auto-install dependencies from the bundled set, or reject with a clear error listing what's missing. Silent dormant is not acceptable for external users. |
+| `ValidateManifest()` gate | ☐ | Single validation function called at install time. Catches malformed manifests early — same pattern as Unicode scan gate. |
+| Package signing hook | ☐ | Optional `signature` field in manifest. `--verify` flag on install path (currently no-op). Five minutes now prevents a breaking manifest schema change post-fork. |
+| OIDC state nonce validation | ☐ | `handlers/auth.go:221` — security TODO. Validate nonce on OIDC callback before accepting tokens. |
+| Schema migration stub decision | ☐ | `handlers/starlark_helpers.go:93–97` — `RunSchemaMigrations` is a no-op stub called during updates. Implement real migrations or remove and document that only additive schema changes are supported. Don't ship a stub that pretends to work. |
+| ICD/SDK runner update pass | ☐ | ICD runner and SDK runner are stale for cluster, backup, chat, realtime, dynamic OpenAPI. Update to cover current API surface. |
+| Stale TODO resolution | ☐ | `main.go:867` (session middleware TODO, stale since v0.2.0). `auth.go:221` (OIDC nonce, covered above). `starlark_helpers.go:96` (migration stub, covered above). Resolve or delete. |
+
+Then fork.

@@ -490,4 +173,7 @@ PG is the consensus layer. Zero new infrastructure. `UNLOGGED` table + `LISTEN/N
 | Chat as extension, not kernel | Human-to-human chat built entirely as library + surface packages. Zero kernel awareness of conversations, messages, or participants. Kernel gains one generic `realtime` module. Proves near-infinite extensibility. LLM participation layers on top via a separate bridge extension — the chat system doesn't know or care whether a participant is human or AI. |
 | PG as consensus layer | Horizontal scaling uses PG as the sole coordinator (UNLOGGED node_registry + LISTEN/NOTIFY). No etcd, Consul, Redis, or Raft. Rationale: system is already tightly coupled to PG; adding a second consensus layer doubles operational complexity for zero benefit at homelab-to-small-team scale. UNLOGGED table is visible to all connections, survives session disconnect, and cleans up automatically on PG crash — correct behavior since all nodes are dead anyway. Sweep-all for health (every node deletes stale rows) is simpler than ring topology and has no edge cases. |
 | Two trigger tiers | Event + webhook triggers are extension-declared (manifest contract, full sandbox). Scheduled tasks are user-created ad-hoc (restricted sandbox — no raw HTTP, no DB table creation, connections-only outbound). Separation keeps extension contracts static and user automation safe. |
-| Scheduled task identity | Tasks run as their creator (RBAC-scoped). Admin-created tasks can opt into system context. Creator deactivation pauses the schedule. Ensures audit trail and permission boundaries. |

+| Scheduled task identity | Tasks run as their creator (RBAC-scoped). Admin-created tasks can opt into system context. Creator deactivation pauses the schedule. Ensures audit trail and permission boundaries. |
+| Builtin package rationale | A builtin must enhance kernel surfaces or be required to demonstrate the platform's own capabilities. **notes** — primary content surface, exercises ext_data/storage/SDK/settings/realtime fully. **chat + chat-core** — primary communication surface, proves the extensibility thesis (100% extension, zero kernel awareness). **mermaid-renderer** — docs surface uses Mermaid diagrams to explain the architecture; without it the platform's own documentation doesn't render (self-bootstrapping). **schedules** — UI for the kernel's scheduled task system; without it users can't manage cron jobs (kernel primitive UI). All others are domain features, examples, dormant, or LLM-only tools — available via registry or `BUNDLED_PACKAGES=*`. |
+| Cluster dashboard retired | `cluster-dashboard` shipped as a standalone surface package (v0.6.0) as an expedient. Health/metrics belong inside the Admin surface as a tab — shared context, no separate nav entry, no install required. Merged in v0.6.4. |
+| Block renderers decoupled from chat | `mermaid-renderer`, `katex-renderer`, `csv-table`, `diff-viewer` shipped with `"requires": ["chat"]` because renderer discovery lived inside the chat surface. These are content renderers, not chat features. v0.6.4 removes the constraint; v0.6.5 lifts renderer registration to the kernel SDK so all surfaces share it without reimplementing discovery. |
