+# Contributing to Switchboard Core
+
+## Development Setup
+
+**Requirements:** Go 1.23+, Node.js 20+ (for frontend tests), SQLite (local dev).
+
+**Build from source:**
+
+```sh
+cd server
+go build -o switchboard-core .
+DB_DRIVER=sqlite DATABASE_URL=/tmp/switchboard.db ./switchboard-core
+```
+
+**Docker (recommended):**
+
+```sh
+docker compose up --build
+# open http://localhost:3000  (default login: admin / admin)
+```
+
+Data persists in the `sb_data` named volume. Reset with `docker compose down -v`.
+
+## Project Structure
+
+```
+server/          Go backend (handlers, store, config, auth, workflow engine)
+src/js/          Browser SDK and built-in surface JS
+packages/        Extension packages (surfaces, libraries, browser extensions)
+  build.sh       Builds each subdirectory into a .pkg archive
+docs/            Documentation markdown (served at /api/v1/docs)
+k8s/             Kubernetes manifests and Helm chart
+```
+
+## Running Tests
+
+**Backend:** `cd server && go test ./...`
+
+**Frontend:** `node --test src/js/__tests__/`
+
+## Code Conventions
+
+- **Go:** Standard formatting via `gofmt`. Handlers in `server/handlers/`,
+  persistence in `server/store/`. Database access goes through the store
+  interface, never directly from handlers.
+- **Browser JS:** Vanilla ES modules + Preact via CDN. No build step for
+  browser code (except the CM6 editor bundle). SDK lives at `src/js/sw/`.
+- **Extensions:** IIFE pattern (see `packages/*/js/script.js`). Register with
+  `sw.renderers` or `sw.slots` via the `sw:ready` event.
+
+## Creating a Package
+
+A package is a ZIP archive (`.pkg`) containing `manifest.json` and optional
+`js/`, `css/`, `assets/`, and `script.star` files. The build script
+(`packages/build.sh`) automates this. See `docs/PACKAGE-FORMAT.md` for the
+full manifest spec and `docs/TUTORIAL-FIRST-EXTENSION.md` for a walkthrough.
+
+## Pull Request Process
+
+1. Create a feature branch from `main`.
+2. Make your changes. Keep commits focused.
+3. Run both Go and JS test suites and confirm they pass.
+4. Submit a PR with a clear description of what changed and why.
+5. Address review feedback, then squash-merge when approved.

 # Switchboard Core — Roadmap
 
-## Current: v0.2.0 — SDK & Triggers
+## Current: v0.6.7 — Native mTLS
 
-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.
 
-### Phase 0 (complete)
+---
+
+## v0.6.0 — MVP
+
+Extension, communication, and operations tracks converge. First
+externally usable release.
+
+Design docs: `docs/DESIGN-cluster-registry.md` — PG-backed cluster registry and self-assembling mesh.
+
+### v0.6.0 — Cluster Registry + HA
+
+PG is the consensus layer. Zero new infrastructure. `UNLOGGED` table + `LISTEN/NOTIFY` replaces etcd/Consul/Redis for homelab-to-small-team scale.
 
 | Step | Status | Description |
 |------|--------|-------------|
-| 1. Module rename | ✅ | `chat-switchboard` → `switchboard-core` |
-| 2. Delete packages | ✅ | 15 Go packages, 29 handler files removed |
-| 3. Gut stores/models | ✅ | 40 → 20 store interfaces, kernel-only models |
-| 4. Fresh migrations | ✅ | 9 files × 2 dialects, 27 tables |
-| 5. Fix compilation | ✅ | `go build ./...` clean, 300+ stale route lines cut |
-| 6. Fix tests | ✅ | 8 test packages pass, ~12K stale test lines pruned |
-| 7. Frontend gut | ✅ | Shell + SDK only, 50+ files of chat/notes/projects code removed |
-| 8. New ICD | ✅ | Full OpenAPI 3.0.3 spec — 160 operations across 22 tag groups |
-| 9. CI/CD + Dockerfile | ✅ | Single unified image, FE/BE split removed, DB names updated, k8s var alignment fixes (resource quantities, image name, rollout deployment name) |
-| 10. Smoke test | ✅ | K8s deploy live at switchboard.gobha.ai/test, nginx BASE_PATH fixed, login→admin flow verified, branding updated |
+| `node_registry` table | ✅ | `UNLOGGED TABLE` — node_id, endpoint, seq, registered_at, heartbeat, stats JSONB. Postgres migration 013. |
+| Node registration | ✅ | Self-registration on startup: `INSERT ... ON CONFLICT DO UPDATE`. `node_id` = `hostname-PID` or `CLUSTER_NODE_ID` env override. |
+| Heartbeat tick | ✅ | Every 10s: update own heartbeat + collect runtime stats (goroutines, heap, GC, uptime, ws_clients). |
+| Stale sweep | ✅ | Every heartbeat tick: `DELETE WHERE heartbeat < now() - 30s`. All nodes run it — idempotent, no ring topology. |
+| Self-eviction | ✅ | If heartbeat UPDATE returns 0 rows: node was swept by peer → log error + `os.Exit(1)`. K8s restarts → re-register. |
+| LISTEN/NOTIFY routing | ✅ | Durable events (messages, state changes) fan-out via `pg_notify`. All replicas receive, push to local WS subscribers, drop if irrelevant. Phase 1: ephemeral events (typing, presence) also via NOTIFY (8KB limit, ~60 bytes each). |
+| Cluster API | ✅ | `GET /api/v1/admin/cluster` — returns `{data: [...]}` envelope with all registered nodes. |
+| Admin cluster dashboard | ✅ | `cluster-dashboard` surface package renders one card per node: node_id, endpoint, uptime, ws_clients, heap, GC pause. JSONB stats — future keys render automatically, no schema migration. Auto-refresh every 10s. |
+| Health endpoint | ✅ | `GET /health` includes `node_id` and `cluster: {size, peers, heartbeat_age_ms}`. |
+| Config | ✅ | `CLUSTER_NODE_ID`, `CLUSTER_HEARTBEAT_INTERVAL` (default 10s), `CLUSTER_STALE_THRESHOLD` (default 30s), `CLUSTER_ENDPOINT` (Phase 2 mesh, auto-detect). |
+| Single-node regression | ✅ | One-node behavior identical to pre-cluster: one registry row, NOTIFY delivers back to same instance. No special-casing. SQLite returns nil store — all cluster code guarded. |
+| Multi-node integration test | ✅ | Docker Compose: 3 instances, shared PG. `ci/e2e-cluster-test.sh`: registration, stale sweep on stop, re-registration on restart. 3 unit tests + 2 handler tests. |
 
-## 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)
+### v0.6.1 — Backup/Restore + Documentation
 
 | 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 |
+| Backup handler | ✅ | `POST /api/v1/admin/backup` streams `.swb` ZIP (JSONL core + ext_data tables + package assets). `POST /api/v1/admin/restore` wipes DB and restores from archive. Dialect-neutral (SQLite + Postgres). |
+| Server-side backups | ✅ | `GET /api/v1/admin/backups` list, `GET /download`, `DELETE`. Store backups in `{STORAGE_PATH}/backups/`. |
+| Admin backup section | ✅ | New "Backup" section under `/admin/backup`. Create (download or server-side), list, download, delete, restore with destructive confirmation. |
+| Documentation API | ✅ | `GET /api/v1/docs` lists, `GET /api/v1/docs/:name` returns raw markdown. Authenticated (not admin-only). |
+| Docs surface | ✅ | Builtin surface at `/docs/:section`. Sidebar navigation, client-side markdown renderer. 5 new docs: Getting Started, Extension Guide, API Reference, Deployment, Package Format. |
+| Tests | ✅ | 6 handler tests (basic backup, ext_data backup, round-trip restore, schema mismatch, dump/restore table, list empty). E2E script `ci/e2e-backup-test.sh`. |
 
-### v0.2.1 — Default Surface + ICD
+### v0.6.2 — Docs Polish + Dynamic OpenAPI
 
 | 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`. |
+| Dark mode fix | ✅ | Added `--bg-code` to CSS variables (dark + light). Replaced all hardcoded light-mode fallbacks in docs CSS with theme-aware variables. Table styling, code blocks, nav items all readable in dark mode. |
+| Loading & error handling | ✅ | Replaced borrowed `settings-placeholder` with docs-specific pulse animation. Added error state with retry button for failed doc list fetch. |
+| Topbar navigation | ✅ | Imported `Topbar` + `UserMenu` into docs surface. Users can now navigate to other surfaces via the avatar menu. |
+| Docs icon + menu entry | ✅ | Added `📖 Docs` entry to UserMenu standard items. Docs accessible from any surface's user menu. |
+| `api_schema` manifest field | ✅ | Optional `api_schema` array in `manifest.json`. Parsed lazily by spec builder. Malformed entries logged and skipped — never blocks extension loading. |
+| OpenAPI spec builder | ✅ | `BuildOpenAPISpec()` merges static kernel spec with extension routes. Tier 1: auto-generated stubs for all `api_routes`. Tier 2: `api_schema` replaces stubs with rich path items (params, body, response). |
+| Dynamic spec endpoint | ✅ | `GET /api/docs/openapi.json` serves merged spec. Swagger UI updated to use JSON endpoint. Static YAML preserved for backward compat. |
+| Tests | ✅ | 7 new handler tests: zero extensions, stubs, rich schema, multi-extension, malformed schema, disabled exclusion, required fields. |
 
-### v0.2.2 — Event Bus + Triggers
+---
+
+## v0.6.x — Hardening
+
+Closes every audit finding before the public release. 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 |
 |------|--------|-------------|
-| 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. |
+| 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 had legacy version annotations (`// v0.29.x:`, `// v0.33.x:`). Single sed pass. |
+| Narrow default bundle | ✅ | Default: `notes`, `chat`, `chat-core`, `mermaid-renderer`, `schedules`. Everything else available via registry or `BUNDLED_PACKAGES=*`. |
 
-### v0.2.3 — SDK + Task Extension
+### 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 |
 |------|--------|-------------|
-| SDK stabilization | ✅ | `sw.api.ext()`, `sw.storage`, `sw.theme.tokens`, `sw.ui`, `sw.slots`, `sw.actions` — six new SDK modules for extension development |
-| Task extension | ✅ | Full task surface rebuilt as Starlark extension: CRUD API, kanban/list views, event triggers, webhook integration, notifications on completion |
+| "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. |
 
-### v0.2.4 — Shell Navigation + Schedules
+### 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 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. |
-| isAdmin RBAC fix | ✅ | `can.js` isAdmin() now checks `surface.admin.access` grant instead of deprecated role column. |
+| 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 delegates to `sw.markdown.renderSync()` + `sw.renderers.runPostRenderers()`. Hand-rolled renderer deleted. |
+| Docs hooks SDK renderer pipeline | ✅ | Docs delegates to `sw.markdown.renderSync()` + `sw.renderers.runPostRenderers()`. Hand-rolled renderer deleted (~160 lines). |
+| Unify markdown renderer | ✅ | `sw.markdown` module lazy-loads `marked` v16 (vendored). Notes, Docs, Chat all consume it. Two hand-rolled parsers deleted. |
+| Sanitize HTML output | ✅ | DOMPurify wired as default post-render step in `sw.markdown`. SVG-safe config allows mermaid output. Notes sanitizes; Docs opts out (system-authored). |
+| Mermaid/KaTeX/CSV/Diff work everywhere | ✅ | Browser extension loader injects renderer scripts into all pages. Extensions register via `sw:ready` event. All four render in Notes, Docs, and Chat. |
+| Docs rewrite for external audience | ✅ | All fork references removed from docs, CHANGELOG, ROADMAP. DESIGN-WORKFLOW-REDESIGN-0.2.6.md replaced with DESIGN-WORKFLOWS.md. |
+| Add Mermaid architecture diagrams | ✅ | Six diagrams in ARCHITECTURE.md: system overview, request flow, extension lifecycle, realtime events, settings cascade, cluster topology. |
+| Surface alias decision | ✅ | Migrated SDK + ICD runner to `/admin/packages/`; aliases removed from main.go. |
+| `CONTRIBUTING.md` + tutorial | ✅ | CONTRIBUTING.md at repo root + docs/TUTORIAL-FIRST-EXTENSION.md walkthrough. |
 
-### v0.2.5 — UI Polish + Dead Code Audit
+### v0.6.7 — Native mTLS
+
+End-to-end mutual TLS without a reverse proxy. Targets systemd+podman deployments where every connection (client→server, node→node) is mTLS. Design: `docs/DESIGN-native-mtls.md`.
 
 | 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. |
+| `TLS_MODE` config | ✅ | Three values: `none` (default, plain HTTP) · `server` (TLS, no client cert) · `mtls` (mutual TLS, client cert required). Independent of `AUTH_MODE`. |
+| TLS server mode | ✅ | Go binary calls `ListenAndServeTLS` directly. `TLS_CERT`, `TLS_KEY`, `TLS_CA` path config. TLS 1.3 minimum, no fallback. `server/config/tls.go` loader + validation. |
+| `MTLSNativeProvider` | ✅ | Reads `r.TLS.PeerCertificates[0]` — no header trust. `Subject.CommonName` → username. `sha256(Raw)` → `external_id`. Auto-provisions `auth_source=mtls`. Renamed existing `mtls.go` → `mtls_proxy.go`. Shared helpers in `mtls_helpers.go`. |
+| Node-to-node mTLS | ✅ | `BuildPeerTLSConfig()` constructs outbound TLS config with node cert + CA pool. Forward-looking — cluster registry is DB-backed (PG LISTEN/NOTIFY), no HTTP peer calls yet. |
+| `switchboard-ca.sh` | ✅ | Shell wrapper around openssl. Three commands: `init` (CA keypair) · `issue-node --name <n> --san <addrs>` (365d) · `issue-user --cn <name>` (90d). All output PEM. |
+| Unit tests | ✅ | Ephemeral CA via `crypto/x509`. Fabricated `PeerCertificates`. Valid cert → user provisioned · no TLS → `ErrNoCert` · empty certs → `ErrNoCert` · no CN → `ErrInvalidCreds`. |
+| Integration tests | ✅ | Real TLS listener on localhost. No cert / wrong CA / expired → TLS handshake rejected. Valid cert → 200. Peer certificate CN + email visibility verified. |
 
-### v0.2.6 — Admin Settings Audit
+### v0.6.6 — Final Hardening
+
+Final pass before public release. Security, correctness, and developer experience.
 
 | 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. |
+| Extension dependency auto-activation | ✅ | Installing a package with unmet `depends`/`requires` auto-installs dependencies from the bundled set. If not bundled: clear error listing what's missing. |
+| `ValidateManifest()` gate | ✅ | Single `ValidateManifest()` function in `package_validate.go`. Called at install time (both upload and bundled). 12 unit tests. |
+| Package signing hook | ✅ | Optional `signature` field in manifest (reserved). `PACKAGE_VERIFY_SIGNATURES` env var (default false, log-only). No cryptographic code yet — schema slot reserved. |
+| OIDC state nonce validation | ✅ | `oidcClaims.Nonce` field added. `ValidateIDTokenNonce()` compares ID token nonce against stored state. Callback rejects mismatched nonces. |
+| Schema migration stub decision | ✅ | Stub replaced with log-only function documenting additive-only policy. Downgrade rejection preserved. |
+| ICD/SDK runner update pass | ✅ | ICD smoke tier: added metrics, cluster, backups, docs, OpenAPI JSON endpoints. SDK admin domain: added metrics, cluster, backups tests. |
+| Stale TODO resolution | ✅ | `main.go` session middleware: replaced with `OptionalAuth()` (auth if token present, anonymous pass-through). `auth.go:221` OIDC nonce: resolved. `starlark_helpers.go:96` migration stub: resolved. |
 
-### v0.2.7 — User Settings Audit
+Then ship.
 
-| 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 | ⬚ | Stop auto-seeding chat-centric extensions (csv-table, diff-viewer, js-sandbox, katex-renderer, mermaid-renderer, regex-tester). Remove `SeedBuiltinPackages`, Dockerfile COPY, and `extensions/builtin/` directory. These extensions are not OBE — they're dormant until a chat surface exists to consume them. |
-| Convert to regular packages | ⬚ | Repackage the 6 extensions as standard `.pkg` archives in `packages/`. Add chat dependency metadata to manifests so they can be installed when the chat extension ships post-MVP. No auto-install — explicit install only, matching the distribution model. |
-
-## 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 — Workflow Design + Schema
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Extension lifecycle | ⬚ | Define permanent vs PoC extensions. Package graduation criteria. Dependency policy. What ships with core vs what's installed separately. |
-| Workflow design session | ⬚ | Define what "workflow" means in the extension-first model. Determine if the existing `workflows` table/handler survives, gets rebuilt, or gets removed. Document the Starlark contract for multi-step automation. See `docs/DESIGN-WORKFLOW-REDESIGN-0.2.6.md`. |
-| Team roles | ⬚ | Different roles per team responsible for different workflow stages. Role-based stage assignment, multi-party validation (2-party sign-off at stage boundaries). |
-| Trigger composition model | ⬚ | How do triggers, schedules, and workflows compose? Event chains, conditional branching, error handling. Design doc before code. |
-| Settings audit pass 2 | ⬚ | Focused audit of team admin + user settings for workflow/team-role changes applied in this series. Validates new team role UI, stage assignment settings, workflow preferences. |
-
-## v0.4.0 — Notes Surface
-
-Obsidian-style rich-text notes rebuilt as an installable surface package.
-Zero platform special-casing. Proves the full extension stack E2E.
-
-- Notes as `.pkg` archive
-- Rich text editor (ProseMirror or similar)
-- Folder tree, backlinks, tags — all extension-provided
-- Markdown import/export
-
-## v0.5.0 — MVP
-
-Extension and operations tracks converge. First externally usable release.
-
-- Package registry (browse, install, update, uninstall)
-- Package distribution model (no auto-install; explicit install only)
-- Health monitoring dashboard
-- Backup/restore tooling
-- Documentation site
+---
 
 ## Post-MVP
 
-- Chat extension (provider registry, streaming, personas, tool system)
+- LLM participation (`llm-bridge` extension: subscribes to `chat.message.created`, calls `provider.complete()`, streams response via `realtime.publish`, posts via `chat.send()`. Bot participants with persona config. Multi-model conversations.)
 - Rich media extensions: image generation, code sandbox, STT/TTS
 - Desktop app (Tauri or Electron)
 - Sidecar tier: container-based extensions
 - Federation: cross-instance package sharing
 - Plugin marketplace with signing and review
-- Mermaid diagrams extension (nice-to-have)
+
+---
 
 ## Design Decisions Log
 
 | Decision | Rationale |
 |----------|-----------|
 | Tasks → extension | Scheduler was the most entangled kernel component (~3,400 lines). Rebuilding as extension validates the trigger system and removes the worst compilation debt. Three trigger primitives (time, webhook, event) replace the monolithic scheduler. |
-| Sessions removed | Channel-based sessions coupled to deleted chat system. Workflow instances need new storage model — either ext_data tables or a dedicated kernel table. |
-| `chat_only` → `custom` | Stage mode `chat_only` implied chat as a kernel concept. Renamed to `custom` which delegates to a surface package, proving extension composability. |
+| Sessions removed | Kernel-managed sessions replaced by workflow instances with dedicated storage (ext_data tables or kernel table). |
+| `custom` stage mode | Stage mode `custom` delegates to a surface package, proving extension composability. Chat-in-workflow is handled by the chat extension, not the kernel. |
 | Providers removed from kernel | Provider configs, model catalog, routing policies — all moved to extension track. Kernel provides credential storage (connections) and the Starlark `provider.complete` module as the interface. |
-| Kernel permissions simplified | From 16 chat-centric permissions to 6 platform permissions. Extensions define their own capability requirements in manifests. |
+| Kernel permissions simplified | 6 platform permissions. Extensions define their own capability requirements in manifests. |
 | Preact+htm retained | 3KB runtime, no build step, works for extension authors without bundler config. KISS. |
 | Single Docker image | Drop the frontend/backend split. Go binary + assets + migrations in one image. Simpler deployment, fewer moving parts. |
 | Admin → RBAC group | The `role` column is pre-RBAC. v0.2.0 replaces it with a seeded "Admins" group + `surface.admin.access` grant. All users auto-join "Everyone" group. Admin middleware becomes a grant check, not a role check. |
@@ -179,6 +184,10 @@ Extension and operations tracks converge. First externally usable release.
 | No new migrations pre-MVP | Edit existing migration SQL files in place. No migration chains until schema is in production. |
 | Notes over Editor | First surface is Obsidian-style notes (rich text, folders, backlinks) instead of a code editor. Notes is a stronger E2E proof — it exercises ext_data, storage, and the SDK more fully than a pure-browser CM6 editor. |
 | No built-in auto-install | Extensions ship in the repo but are not auto-installed. Distribution model TBD — explicit install only. Keeps the kernel clean and avoids opinionated defaults. |
-| Chat → post-MVP | Chat extension (providers, streaming, personas) is valuable but not MVP-critical. The platform must prove itself with simpler surfaces first. Chat moves to post-MVP track. |
+| 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. |
+| 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. |

-# Switchboard Core — Session Turnover
-**Date**: 2026-03-26
-**Author**: Jeffrey Smith (jasafpro@gmail.com)
-**Session**: v0.2.0 PR 1 — Full RBAC migration
-
----
-
-## What Was Done
-
-### PR 1: Admin → RBAC group migration — COMPLETE
-Branch `feat/admin-rbac-migration` (PR #1), 3 commits:
-
-1. **Admin → RBAC group migration** — `surface.admin.access` permission +
-   Admins system group replaces hardcoded `role == "admin"` checks. Admin
-   bypass removed from `RequirePermission`. Bootstrap/seed/OIDC/admin handlers
-   sync group membership.
-
-2. **Remove token budgets + allowed models from groups** — Provider-era cruft:
-   `token_budget_daily`, `token_budget_monthly`, `allowed_models` columns,
-   `ResolveTokenBudget()`, `ResolveModelAllowlist()`, and all store/handler/UI
-   code deleted. -283 lines.
-
-3. **Drop `users.role` column** — Full RBAC. Zero magic roles. The `role` column,
-   `UserRoleAdmin`/`UserRoleUser` constants, `CountByRole()`, `DefaultRole` config,
-   `role` in JWT claims, and all role-based shortcuts removed. Everyone group
-   membership is now explicit (all users added on create). 28 files changed.
-
-**Net result: -364 lines across 3 commits.**
-
-### Architecture after this PR:
-
-- **Everyone group** (`00000000...0001`): all users explicitly added on creation.
-  Carries `extension.use`, `workflow.submit`.
-- **Admins group** (`00000000...0002`): carries all 7 kernel permissions including
-  `surface.admin.access`. Not special-cased — just a group with permissions.
-- **Permission resolution**: union of all group memberships. No implicit groups,
-  no role shortcuts, no admin bypass.
-- **Admin middleware**: checks `surface.admin.access` grant via `resolveAndCachePerms`.
-- **JWT claims**: `user_id` + `email` only. No role.
-- **OIDC**: `isIdPAdmin()` maps IdP role claim → Admins group membership.
-  No `role` column writes.
-- **User creation paths**: builtin register, OIDC auto-provision, mTLS auto-provision,
-  admin create, bootstrap, seed — all call `EnsureEveryoneGroup()`.
-

-
-## Known Issues
-
-1. **Frontend test job**: FE test suite may have remaining stale references
-   from Phase 0 gut (pre-existing)
-2. **Traefik middleware**: `rbac-traefik.yaml` needs one-time manual apply
-   by cluster admin (pre-existing, non-blocking)
-3. **`SEED_USERS`**: Not set in K8s secrets (pre-existing)
-4. **Editor modules**: `src/editor/*.mjs` still reference "Chat Switchboard"
-   (pre-existing, low priority)
-5. **K8s deploy**: PR not yet merged to main — CI/CD will need a deploy after merge
-
----
-
-## What's Next
-
-### Merge PR #1
-Review and merge `feat/admin-rbac-migration` to main.
-
-### v0.2.0 — Remaining PRs
-
-**PR 2: Settings cascade**
-- Add `user_overridable` flag to settings schema
-- RBAC controls scope auth (admin → global, team-admin → team, user → personal)
-- Resolution: user → team → global (first non-null wins)
-
-**PR 3: ICD (API contract)**
-- Generate full OpenAPI spec from registered routes
-- Document kernel-only endpoints
-
-**PR 4: Trigger system**
-- Time triggers (cron), webhook (inbound HTTP), event (bus subscription)
-- Extensions register match expressions at install
-
-**PR 5: SDK stabilization**
-- `sb.slots()`, `sb.actions`, `sb.api.ext()`, `sb.storage`
-- Theme tokens exposed to extensions

-## Architecture Decisions (this session)
-
-| Decision | Detail |
-|----------|--------|
-| Full RBAC — no magic roles | `users.role` column dropped entirely. All authorization through group membership + permission grants. |
-| Explicit Everyone membership | No implicit "all users get Everyone perms". Every user added to Everyone group on create. `member_count` reflects reality. |
-| Admins group not special-cased | Code never checks group identity — only checks for `surface.admin.access` permission. Any group can grant it. |
-| No new migrations pre-MVP | Edit existing SQL files in place. Schema isn't in production. |
-| JWT simplified | Claims carry `user_id` + `email` only. Permissions resolved server-side from groups on every request. |
-| OIDC role → group sync | `isIdPAdmin()` replaces `resolveRole()`. IdP admin claim maps to Admins group membership, not a DB column. |
-| Token budgets/allowed models removed | Provider-era cruft. Belongs in a future provider extension, not the kernel. |

+  ghcr.io/switchboard-core/switchboard-core:latest
+```
+
+This runs with SQLite and PVC storage. Suitable for evaluation and small teams.
+
+## Docker Compose with PostgreSQL
+
+```yaml

+
+volumes:
+  pg_data:
+  sb_storage:
+```
+
+## Kubernetes
+
+See the `k8s/` directory for example manifests. Key considerations:
+
+- Set `POSTGRES_HOST`, `POSTGRES_USER`, `POSTGRES_PASSWORD`, `POSTGRES_DB` env vars (assembled into DSN automatically).
+- Liveness probe: `/healthz/live`. Readiness probe: `/healthz/ready`.
+- Mount a PVC at `/data/storage` or configure S3.
+- Store `JWT_SECRET` and `ENCRYPTION_KEY` in Kubernetes Secrets.
+- Registry: `registry.gobha.me:5000/xcaliber/switchboard-core`.

+| `S3_ACCESS_KEY` | Access key |
+| `S3_SECRET_KEY` | Secret key |
+| `S3_FORCE_PATH_STYLE` | `true` for MinIO/Ceph |
+
+### Cluster Variables (Multi-Replica)
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `CLUSTER_NODE_ID` | hostname-PID | Override for deterministic node identity |
+| `CLUSTER_HEARTBEAT_INTERVAL` | `10s` | Heartbeat tick frequency |
+| `CLUSTER_STALE_THRESHOLD` | `30s` | 3x heartbeat = stale node |
+| `CLUSTER_ENDPOINT` | auto-detect | Advertised address for peer mesh |
+
+## Database Configuration
+
+**PostgreSQL** (recommended for production):
+
+```bash
+DATABASE_URL="postgres://user:pass@host:5432/switchboard?sslmode=require"
+```
+
+**SQLite** (dev, test, edge deployments):
+
+```bash
+DB_DRIVER=sqlite
+DATABASE_URL=/data/switchboard.db
+```
+
+Both databases are first-class -- every query compiles and passes tests on both. The driver is auto-detected from `DATABASE_URL` if `DB_DRIVER` is not set.
+
+## Cluster Mode
+
+Multi-replica HA requires PostgreSQL. The kernel uses PG-backed WebSocket tickets and rate limit counters to coordinate across replicas. A cluster registry with heartbeat and stale sweep tracks active nodes.
+
+View cluster status in Admin > Cluster or via `GET /api/v1/admin/cluster`.
+
+## Storage Backends
+
+**PVC**: Auto-detected if the storage path is writable. Mount a volume at `/data/storage`.
+
+**S3-compatible**: Set `STORAGE_BACKEND=s3` and provide S3 variables. Works with AWS S3, MinIO, and Ceph.
+
+## Backup and Restore
+
+Available via Admin UI or API:
+
+```
+POST /api/v1/admin/backup       # Create backup
+GET  /api/v1/admin/backups      # List backups
+GET  /api/v1/admin/backups/:name  # Download backup
+POST /api/v1/admin/restore      # Restore from backup
+DELETE /api/v1/admin/backups/:name  # Delete backup
+```
+
+## Monitoring
+
+| Endpoint | Purpose |
+|----------|---------|
+| `/health` | Basic health check |
+| `/healthz/live` | Kubernetes liveness probe |
+| `/healthz/ready` | Kubernetes readiness probe |
+| `/metrics` | Prometheus metrics |

+# Extension Lifecycle: Permanent vs PoC
+
+## Overview
+
+Packages (extensions) fall into two categories: **permanent** and **PoC** (proof-of-concept).
+This classification drives install-by-default behavior and maintenance expectations.
+
+## Permanent Packages
+
+Permanent packages are part of the platform kernel or essential surfaces. They are always
+available and maintained by core contributors.
+
+| Package          | Reason                         |
+|------------------|--------------------------------|
+| admin            | System administration surface  |
+| team-admin       | Team management surface        |
+| settings         | User settings surface          |
+| login            | Authentication surface         |
+| welcome          | Onboarding / empty-state       |
+
+## PoC Packages
+
+Everything else in `packages/` is PoC. These demonstrate the extension model but are not
+required for platform operation. Examples: tasks, schedules, dashboard, editor, git-board,
+icd-test-runner, sdk-test-runner.
+
+Retired builtins (csv-table, diff-viewer, js-sandbox, katex-renderer, mermaid-renderer,
+regex-tester) are PoC packages migrated from the kernel during the v0.2.9 retirement.
+
+## Graduation Criteria
+
+A PoC package may be promoted to permanent when all of the following are met:
+
+1. **Active usage** — 3+ active users or teams depend on it.
+2. **Test coverage** — At least basic smoke tests exist (Starlark or integration).
+3. **No kernel special-casing** — The package operates entirely through the public extension
+   API. No `if pkg == "X"` branches in core.
+4. **Documentation** — README with install instructions, config options, and screenshots.
+5. **Maintenance owner** — A named contributor commits to reviewing issues.
+
+## Deprecation
+
+Packages that no longer meet graduation criteria (e.g., zero usage for 6 months) may be
+archived. Archived packages remain installable but receive no updates.
+
+## Install Model
+
+All packages use explicit installation: `POST /api/v1/packages/:id/install`. There is no
+auto-install. The kernel ships clean; teams choose what they need.

+# Trigger Composition: Triggers, Schedules, and Workflows
+
+## Overview
+
+Three automation primitives exist in the platform: **triggers** (event-driven), **schedules**
+(time-driven), and **workflows** (multi-step state machines). This document defines how they
+compose without creating circular dependencies.
+
+## Composition Rules
+
+### Triggers can start workflows
+
+A trigger's Starlark handler may call `workflow.start(workflow_id, data)` to create a new
+workflow instance. This is the primary entry point for event-driven workflow initiation.
+
+Example: a `ticket.created` trigger fires and starts an approval workflow.
+
+### Schedules can start workflows
+
+A schedule's Starlark handler may also call `workflow.start(...)`. This enables time-based
+batch processing workflows.
+
+Example: a daily 9am schedule starts a standup collection workflow.
+
+### Workflows emit events that triggers listen to
+
+Workflow lifecycle events (`workflow.started`, `workflow.advanced`, `workflow.completed`,
+`workflow.signoff`, etc.) are published on the event bus. Triggers may subscribe to these
+events to perform side effects (notifications, external API calls, audit logging).
+
+### Workflows cannot start triggers or schedules
+
+Workflows do not directly invoke triggers or create schedules. Workflow Starlark hooks
+operate within the workflow's own context and do not have access to trigger/schedule
+management APIs. This prevents uncontrolled fan-out.
+
+## Circular Invocation Guard
+
+The automated stage cycle guard (max 10 consecutive automated stages) already prevents
+infinite loops within a single workflow. Cross-workflow cycles are prevented by this rule:
+
+**A workflow event handler (trigger) may start a new workflow instance, but the new instance
+is not processed synchronously.** It enters the work queue as a separate execution context.
+The bus does not re-enter the originating workflow's advance call.
+
+This means:
+- `workflow.completed` trigger → `workflow.start(B)` is allowed (async).
+- Workflow A automated stage → `workflow.start(B)` where B immediately completes and
+  triggers A again → allowed but rate-limited by the cycle guard on each individual workflow.
+
+## Not Supported (by design)
+
+- Triggers cannot modify a running workflow instance (read-only access via Starlark builtins).
+- Schedules cannot advance or cancel workflow instances directly.
+- Workflows cannot create, modify, or delete triggers or schedules.
+
+These restrictions keep the composition model simple and auditable.

-# Workflow Redesign — v0.2.6
-
-**Status:** Draft
-**Branch:** `feat/workflow-redesign-v0.2.6`
-**Date:** 2026-03-27
-**Context:** Mapping viable ideas from chat-switchboard v0.39.x onto core's extension-first architecture.
-
----
-
-## 1. Guiding Principles
-
-1. **Workflows are kernel.** Definitions, instances, the stage graph, form validation, and
-   assignment queues are platform primitives — not extensions.
-2. **Execution is delegated.** How a stage renders or collects data is an extension concern.
-   The kernel says *what* a stage needs; a surface package provides the *how*.
-3. **No chat assumptions.** The kernel never references personas, channels, or AI providers.
-   A chat extension can participate in workflows, but the workflow engine does not depend on it.
-4. **Public access is a platform capability.** Anonymous/public sessions are not workflow-specific —
-   they are a kernel-level feature that any surface can opt into. Workflows *consume* public
-   access; they don't own it. See §15.
-5. **Edit existing migrations.** Per the design-decisions log: no migration chains until the
-   schema is in production. New tables get new files; modified tables are edited in place.
-
----
-
-## 2. Disposition Index
-
-Every item below is classified:
-
-| Tag | Meaning |
-|-----|---------|
-| **🗑 TRASH** | Remove from core. Vestigial chat-switchboard concept that doesn't fit. |
-| **✏️ MOD** | Exists in core today — modify in place. |
-| **➕ ADD** | New to core. Requires new code/tables. |
-| **✅ KEEP** | Already correct in core. No changes needed. |
-
----
-
-## 3. Schema Changes
-
-### 3a. `007_workflows.sql` — edit in place
-
-#### `workflows` table
-
-| Column | Disposition | Action |
-|--------|-------------|--------|
-| `entry_mode` | ✏️ MOD | Current values: `public_link`, `team_only`. Keep the column but change its meaning — it becomes a workflow-level default/flag that says "this workflow has at least one public stage." The real visibility control moves to per-stage `audience`. See note below. |
-| All other columns | ✅ KEEP | Clean. No chat coupling. |
-
-**Note on `entry_mode`:** Chat-switchboard treated this as a binary toggle — the whole
-workflow was either public or not. Real workflows mix audiences: internal setup → public
-form → internal review → public confirmation. The per-stage `audience` field (see below)
-is the source of truth. `entry_mode` on the workflow becomes a convenience flag: if any
-stage has `audience = 'public'`, the workflow is public-entry eligible. This avoids a
-full schema break — existing code that checks `entry_mode` still works, it just gets set
-automatically when stages are saved.
-
-#### `workflow_stages` table
-
-| Column | Disposition | Action |
-|--------|-------------|--------|
-| `persona_id` | 🗑 TRASH | Drop column. Personas are a chat-extension concept. If a stage needs an AI participant, the stage's `surface_pkg_id` extension handles that internally. The comment in the migration already acknowledges this ("personas are extensions now") but the column is still there. Remove it. |
-| `stage_mode` CHECK | ✏️ MOD | Current: `form_only`, `form_chat`, `review`, `custom`. Replace with: `form`, `review`, `delegated`, `automated`. See §4 for definitions. `form_chat` is trash (chat coupling). `form_only` renames to `form`. `custom` renames to `delegated` (clearer intent). `automated` is new (no UI, Starlark-only). |
-| `history_mode` | 🗑 TRASH | Drop column. This controlled how much chat history a persona saw across stages. Core has no chat history. If a delegated surface needs context management, it reads `stage_data` — that's the contract. |
-| `audience` | ➕ ADD | `TEXT NOT NULL DEFAULT 'team'` with CHECK `('team', 'public', 'system')`. Controls who interacts with this stage. `team` = authenticated team members only (internal). `public` = anonymous visitors via entry token (the "public-ish" stage). `system` = no human interaction, automated only. A workflow can freely alternate: team→public→team→public. The kernel enforces this: public stages are accessible via token auth, team stages require JWT, system stages have no UI. |
-| `stage_type` | ➕ ADD | `TEXT NOT NULL DEFAULT 'simple'` with CHECK `('simple', 'dynamic', 'automated')`. Drives the graph engine: `simple` = declarative rules only, `dynamic` = Starlark hook resolves next stage, `automated` = no human UI, fires hook on entry and auto-advances. |
-| `starlark_hook` | ➕ ADD | `TEXT` (nullable). Package-qualified entry point for dynamic/automated stages. Format: `package_id:entry_point`. NULL for simple stages. |
-| `branch_rules` | ➕ ADD | `JSONB NOT NULL DEFAULT '[]'`. Replaces the overloaded `transition_rules` for simple stage branching. Array of `{field, op, value, target_stage}`. Evaluated before `starlark_hook`, before ordinal fallback. |
-| `transition_rules` | ✏️ MOD | Rename to `stage_config`. This JSONB blob was doing double duty (routing rules + on_advance hooks + auto_assign). Routing moves to `branch_rules`. What remains is stage-specific config that the kernel or surface reads: `{on_advance: {package_id, entry_point}, auto_assign: "round_robin"}`. |
-| `assignment_team_id` | ✅ KEEP | Clean. Kernel concept. |
-| `form_template` | ✅ KEEP | Kernel concern — structured data schema. |
-| `auto_transition` | ✅ KEEP | Kernel concern — skip human interaction. |
-| `surface_pkg_id` | ✅ KEEP | The delegation pointer. Required for `delegated` mode stages. |
-| `sla_seconds` | ✅ KEEP | Kernel concern — time budget per stage. |
-
-#### `workflow_versions` table
-
-| Column | Disposition | Notes |
-|--------|-------------|-------|
-| All existing columns | ✅ KEEP | Immutable snapshots. No changes needed. |
-
-### 3b. `007_workflows.sql` — add new tables (same file)
-
-#### ➕ ADD `workflow_instances`
-
-Replaces the channel-based instance model from chat-switchboard. This is the execution record.
-
-```sql
-CREATE TABLE IF NOT EXISTS workflow_instances (
-    id                UUID PRIMARY KEY DEFAULT gen_random_uuid(),
-    workflow_id       UUID NOT NULL REFERENCES workflows(id) ON DELETE CASCADE,
-    workflow_version  INTEGER NOT NULL,
-    current_stage     INTEGER NOT NULL DEFAULT 0,
-    stage_data        JSONB NOT NULL DEFAULT '{}',
-    status            TEXT NOT NULL DEFAULT 'active'
-                          CHECK (status IN ('active', 'completed', 'cancelled', 'stale', 'error')),
-    started_by        UUID REFERENCES users(id) ON DELETE SET NULL,
-    entry_token       TEXT,  -- for public_link resumption
-    metadata          JSONB NOT NULL DEFAULT '{}',
-    stage_entered_at  TIMESTAMPTZ NOT NULL DEFAULT NOW(),
-    created_at        TIMESTAMPTZ NOT NULL DEFAULT NOW(),
-    updated_at        TIMESTAMPTZ NOT NULL DEFAULT NOW()
-);
-
-CREATE INDEX IF NOT EXISTS idx_wf_instances_workflow
-    ON workflow_instances(workflow_id, status);
-CREATE INDEX IF NOT EXISTS idx_wf_instances_status
-    ON workflow_instances(status) WHERE status = 'active';
-CREATE UNIQUE INDEX IF NOT EXISTS idx_wf_instances_token
-    ON workflow_instances(entry_token) WHERE entry_token IS NOT NULL;
-
-DROP TRIGGER IF EXISTS wf_instances_updated_at ON workflow_instances;
-CREATE TRIGGER wf_instances_updated_at BEFORE UPDATE ON workflow_instances
-    FOR EACH ROW EXECUTE FUNCTION update_updated_at();
-```
-
-**Rationale:** Chat-switchboard used `channels` as instances — that table carried message trees,
-AI context windows, participant lists, and other chat concerns. Core needs a purpose-built table
-that holds only workflow execution state: which version, which stage, accumulated data, lifecycle status.
-
-#### ➕ ADD `workflow_assignments`
-
-Dropped during the fork ("channel-dependent, rebuild as needed" — see 007 header comment).
-Now rebuilt as a kernel primitive.
-
-```sql
-CREATE TABLE IF NOT EXISTS workflow_assignments (
-    id            UUID PRIMARY KEY DEFAULT gen_random_uuid(),
-    instance_id   UUID NOT NULL REFERENCES workflow_instances(id) ON DELETE CASCADE,
-    stage         INTEGER NOT NULL,
-    team_id       UUID NOT NULL REFERENCES teams(id) ON DELETE CASCADE,
-    assigned_to   UUID REFERENCES users(id) ON DELETE SET NULL,
-    status        TEXT NOT NULL DEFAULT 'unassigned'
-                      CHECK (status IN ('unassigned', 'claimed', 'completed', 'cancelled')),
-    review_data   JSONB NOT NULL DEFAULT '{}',
-    claimed_at    TIMESTAMPTZ,
-    completed_at  TIMESTAMPTZ,
-    created_at    TIMESTAMPTZ NOT NULL DEFAULT NOW()
-);
-
-CREATE INDEX IF NOT EXISTS idx_wf_assignments_instance
-    ON workflow_assignments(instance_id, stage);
-CREATE INDEX IF NOT EXISTS idx_wf_assignments_team_status
-    ON workflow_assignments(team_id, status) WHERE status IN ('unassigned', 'claimed');
-CREATE INDEX IF NOT EXISTS idx_wf_assignments_user
-    ON workflow_assignments(assigned_to) WHERE assigned_to IS NOT NULL;
-```
-
-**Claim lock:** Same optimistic pattern from chat-switchboard:
-`UPDATE ... WHERE id = $1 AND status = 'unassigned'` — if `rows_affected == 0`, already claimed.
-
-### 3c. New migration file: `012_workflow_instances.sql`
-
-Wait — per the principle, new *tables* get new files. But we're also editing 007. Decision:
-
-**Put the new tables in 007_workflows.sql.** The schema isn't in production. Keep all workflow
-DDL in one file. When the schema *is* in production (post-MVP), new additions get numbered
-migrations. This is consistent with the existing design-decisions log entry:
-"No new migrations pre-MVP."

-## 4. Stage Mode Redesign
-
-### Current (trash/rename)
-
-| Current Mode | Disposition | Rationale |
-|-------------|-------------|-----------|
-| `form_only` | ✏️ MOD → `form` | Rename. Drop the `_only` suffix — there's no `form_chat` to distinguish from anymore. |
-| `form_chat` | 🗑 TRASH | Chat coupling. If you want a form + AI conversation, use `delegated` with a chat surface package. |
-| `review` | ✅ KEEP | Team member reviews accumulated data. Pure kernel concept. |
-| `custom` | ✏️ MOD → `delegated` | Rename for clarity. "Custom" is vague. "Delegated" makes the contract explicit: the kernel delegates stage execution to `surface_pkg_id`. |
-
-### New modes
-
-| Mode | Disposition | Description |
-|------|-------------|-------------|
-| `form` | ✏️ MOD (renamed) | Kernel renders `form_template`, validates submission, merges into `stage_data`. No extension needed. |
-| `review` | ✅ KEEP | Assignment queue stage. Team member claims, reviews `stage_data`, adds `review_data`, completes. Kernel-rendered. |
-| `delegated` | ✏️ MOD (renamed) | Kernel hands off to `surface_pkg_id`. The surface package receives the instance context (stage_data, form_template, metadata) and calls back to advance. This is where chat, AI, or any custom UX lives. |
-| `automated` | ➕ ADD | No UI. On stage entry, kernel fires `starlark_hook`, merges returned data into `stage_data`, and auto-advances. For enrichment, API calls, validation, routing decisions. |
-
-### Stage type vs stage mode
-
-These are orthogonal:
-
-- **`stage_type`** controls *how the next stage is chosen*: `simple` (declarative branch_rules), `dynamic` (Starlark hook returns target), `automated` (hook + auto-advance).
-- **`stage_mode`** controls *how the stage executes*: `form`, `review`, `delegated`, `automated`.
-
-An `automated` stage_type with `automated` stage_mode is the common case for system stages,
-but you can have a `dynamic` stage_type with `form` stage_mode (the form collects data, then a
-Starlark hook decides where to go next based on the submission).
-

-
-## 5. Model Changes
-
-### `server/models/workflow.go`
-
-#### WorkflowStage struct — ✏️ MOD
-
-```go
-// TRASH: Remove these fields
-// PersonaID        *string         `json:"persona_id,omitempty"`
-// HistoryMode      string          `json:"history_mode"`
-
-// MOD: Rename transition_rules → stage_config
-// TransitionRules  json.RawMessage `json:"transition_rules"`
-StageConfig      json.RawMessage `json:"stage_config"`
-
-// ADD: New fields
-Audience         string          `json:"audience"`           // team | public | system
-StageType        string          `json:"stage_type"`         // simple | dynamic | automated
-StarlarkHook     *string         `json:"starlark_hook,omitempty"` // package_id:entry_point
-BranchRules      json.RawMessage `json:"branch_rules"`       // [{field, op, value, target_stage}]
-```
-
-#### Stage mode constants — ✏️ MOD
-
-```go
-// TRASH
-// StageModeFormOnly = "form_only"
-// StageModeFormChat = "form_chat"
-
-// MOD (rename)
-StageModeForm      = "form"       // was form_only
-StageModeDelegated = "delegated"  // was custom
-
-// KEEP
-StageModeReview    = "review"
-
-// ADD
-StageModeAutomated = "automated"
-
-// ADD: Stage type constants
-StageTypeSimple    = "simple"
-StageTypeDynamic   = "dynamic"
-StageTypeAutomated = "automated"
-
-// ADD: Audience constants
-AudienceTeam   = "team"
-AudiencePublic = "public"
-AudienceSystem = "system"
-```
-
-#### ➕ ADD: WorkflowInstance model
-
-```go
-type WorkflowInstance struct {
-    ID              string          `json:"id"`
-    WorkflowID      string          `json:"workflow_id"`
-    WorkflowVersion int             `json:"workflow_version"`
-    CurrentStage    int             `json:"current_stage"`
-    StageData       json.RawMessage `json:"stage_data"`
-    Status          string          `json:"status"` // active | completed | cancelled | stale | error
-    StartedBy       *string         `json:"started_by,omitempty"`
-    EntryToken      *string         `json:"entry_token,omitempty"`
-    Metadata        json.RawMessage `json:"metadata"`
-    StageEnteredAt  time.Time       `json:"stage_entered_at"`
-    CreatedAt       time.Time       `json:"created_at"`
-    UpdatedAt       time.Time       `json:"updated_at"`
-}
-```
-
-#### ➕ ADD: WorkflowAssignment model
-
-```go
-type WorkflowAssignment struct {
-    ID          string          `json:"id"`
-    InstanceID  string          `json:"instance_id"`
-    Stage       int             `json:"stage"`
-    TeamID      string          `json:"team_id"`
-    AssignedTo  *string         `json:"assigned_to,omitempty"`
-    Status      string          `json:"status"` // unassigned | claimed | completed | cancelled
-    ReviewData  json.RawMessage `json:"review_data"`
-    ClaimedAt   *time.Time      `json:"claimed_at,omitempty"`
-    CompletedAt *time.Time      `json:"completed_at,omitempty"`
-    CreatedAt   time.Time       `json:"created_at"`
-}
-```
-
-#### TypedFormTemplate, FormField, FormValidation — ✅ KEEP
-
-All form types are clean kernel code. No changes.
-
-#### ValidateFormData — ✅ KEEP
-
-Pure data validation. No chat coupling.
-

-
-## 6. Store Interface Changes
-
-### `server/store/workflow_iface.go` — ✏️ MOD + ➕ ADD
-
-Current interface is definition-only (CRUD workflows + stages + versions).
-Add instance and assignment operations.
-
-```go
-type WorkflowStore interface {
-    // ── Definition CRUD (KEEP — no changes) ──────────
-    Create(ctx context.Context, w *models.Workflow) error

-}
-```

-
-## 7. Handler Changes
-
-### `server/handlers/workflows.go` — ✏️ MOD
-
-**Stage CRUD updates** — reflect new field names in CreateStage/UpdateStage:
-- Remove `persona_id` and `history_mode` from bind/validation.
-- Add `stage_type`, `starlark_hook`, `branch_rules` to bind/validation.
-- Rename `transition_rules` → `stage_config` in bind/validation.
-- Update `stage_mode` CHECK to new set: `form`, `review`, `delegated`, `automated`.
-- Validate: `delegated` requires `surface_pkg_id`. `dynamic`/`automated` stage_type requires `starlark_hook`.
-
-### `server/handlers/workflow_hooks.go` — ✏️ MOD
-
-**Rename:** `channelID` parameter → `instanceID` in `FireOnAdvanceHook` signature.
-The hook context dict changes from `{channel_id, ...}` to `{instance_id, ...}`.
-
-The `jsonToStarlark` helper referenced on line 81 lives in
-`server/handlers/starlark_helpers.go`. Consider consolidating with `goToStarlark` in
-`server/triggers/event.go` — two independent Go→Starlark converters is tech debt.
-
-### `server/handlers/workflow_team.go` — ✅ KEEP
-
-Team-scoped wrappers. Clean delegation pattern. No changes.
-
-### `server/handlers/workflow_packages.go` — ✏️ MOD
-
-Update `workflowPkgStage` struct:
-- Remove `PersonaID`, `HistoryMode` fields.
-- Add `StageType`, `StarlarkHook`, `BranchRules` fields.
-- Rename `TransitionRules` → `StageConfig`.
-
-Update `ExportWorkflowPackage` and `InstallWorkflowFromManifest` accordingly.
-
-### ➕ ADD `server/handlers/workflow_instances.go`
-
-New handler file for instance lifecycle:
-
-```
-POST   /api/v1/workflows/:id/start           → Start (create instance from latest published version)
-GET    /api/v1/workflows/instances/:iid       → GetInstance
-POST   /api/v1/workflows/instances/:iid/advance → Advance (submit stage data, resolve next)
-POST   /api/v1/workflows/instances/:iid/cancel  → Cancel
-GET    /api/v1/workflows/:id/instances        → ListInstances (by workflow, optionally by status)
-```
-
-Public entry (for `public_link` workflows):
-```
-POST   /api/v1/workflows/entry/:slug          → StartPublic (no auth, generates entry_token)
-GET    /api/v1/workflows/entry/:token          → ResumePublic (retrieve instance by token)
-POST   /api/v1/workflows/entry/:token/advance  → AdvancePublic (submit data via token)
-```
-
-### ➕ ADD `server/handlers/workflow_assignments.go`
-
-New handler file for the assignment queue:
-
-```
-GET    /api/v1/teams/:teamId/assignments         → ListTeamAssignments (filterable by status)
-POST   /api/v1/teams/:teamId/assignments/:id/claim   → Claim
-POST   /api/v1/teams/:teamId/assignments/:id/unclaim  → Unclaim
-POST   /api/v1/teams/:teamId/assignments/:id/complete → Complete (with review_data)
-POST   /api/v1/teams/:teamId/assignments/:id/cancel   → Cancel
-GET    /api/v1/assignments/mine                  → ListMyAssignments (across teams)
-```
-
----
-
-## 8. Routing Engine Changes
-
-### `server/workflow/routing.go` — ✏️ MOD
-
-The existing `ResolveNextStage` evaluates `transition_rules.conditions[]`. This needs to
-become a two-phase resolution that respects the new `stage_type`:
-
-```
-Phase 1: Evaluate branch_rules (declarative, for simple + dynamic types)
-Phase 2: If no match AND stage_type == dynamic → fire starlark_hook
-Phase 3: Fallback → currentStage + 1
-```
-
-For `automated` stage_type, the engine fires `starlark_hook` on entry (not for routing — for
-data enrichment), then routes via branch_rules or ordinal fallback. The routing call happens
-*after* the hook returns.
-
-**Concrete changes:**
-- `ResolveNextStage` signature: add `stageType string, starlarkHook *string, runner *sandbox.Runner` parameters.
-- Extract branch_rules evaluation from the current `TransitionRulesWithConditions` (which reads from `transition_rules` JSON) into a dedicated function that reads from the new `branch_rules` field.
-- `TransitionRulesWithConditions` struct → rename to `StageConfig`, remove `Conditions` field (moved to branch_rules), keep `AutoAssign` and `OnAdvance`.
-
-### `server/workflow/` — ➕ ADD `engine.go`
-
-New file: the stage execution engine. Orchestrates the advance lifecycle:
-
-```
-1. Load instance + version snapshot
-2. Validate current stage allows advancement (status checks)
-3. If current stage has form_template → validate submitted data
-4. Merge submitted data into stage_data
-5. Fire on_advance hook (if configured in stage_config)
-6. Resolve next stage (branch_rules → starlark_hook → ordinal)
-7. If next stage is past last stage → complete instance
-8. If next stage is automated → fire its hook, recurse to step 6
-9. If next stage has assignment_team_id → create WorkflowAssignment
-10. Update instance (current_stage, stage_data, stage_entered_at)
-11. Emit bus events (workflow.advanced, workflow.assigned, workflow.completed)
-```
-
-### `server/workflow/` — ➕ ADD `automated.go`
-
-Handles `automated` stage execution: fire the Starlark hook, merge returned data, and
-auto-advance. Includes a cycle guard (max 10 consecutive automated stages) to prevent
-infinite loops from misconfigured workflows.
-
----
-
-## 9. Event Bus Updates
-
-### `server/events/types.go` — ✏️ MOD
-
-Current workflow events are fine but incomplete. Add:
-
-| Event | Direction | Disposition | Trigger |
-|-------|-----------|-------------|---------|
-| `workflow.assigned` | DirToClient | ✅ KEEP | Assignment created |
-| `workflow.claimed` | DirToClient | ✅ KEEP | Assignment claimed |
-| `workflow.advanced` | DirToClient | ✅ KEEP | Stage transition |
-| `workflow.completed` | DirToClient | ✅ KEEP | Instance completed |
-| `workflow.cancelled` | DirToClient | ➕ ADD | Instance cancelled |
-| `workflow.started` | DirToClient | ➕ ADD | Instance created |
-| `workflow.sla.warning` | DirToClient | ➕ ADD | SLA at 80% threshold |
-| `workflow.sla.breached` | DirToClient | ➕ ADD | SLA exceeded |
-| `workflow.error` | DirLocal | ➕ ADD | Hook execution failure |
-
----
-
-## 10. Starlark Module Updates
-
-### `server/sandbox/workflow_module.go` — ✏️ MOD
-
-The `BuildWorkflowModule` (in `workflow_module.go`, not `modules.go`) currently exists but
-targets the old channel-based model. It currently only exposes `get_definition`.
-Rebuild to expose instance-oriented operations:
-
-```python
-# Available to extensions with workflow.read or workflow.write permission
-workflow.get_instance(instance_id)           # → instance dict
-workflow.get_stage_data(instance_id)         # → stage_data dict
-workflow.set_stage_data(instance_id, data)   # → merge into stage_data
-workflow.advance(instance_id)                # → trigger advance (write perm)
-workflow.get_assignments(instance_id)        # → assignment list
-```
-
-The old `workflow_advance()` function that chat-switchboard's personas called is gone.
-Extensions call `workflow.advance()` which delegates to the same engine as the HTTP handler.
-
----
-
-## 11. Salvage Map from chat-switchboard v0.39.x
-
-What was planned there, and what happens to each idea in core:
-
-### v0.39.0 — Stage Graph Engine + Form Builder
-
-| Component | Disposition | Core equivalent |
-|-----------|-------------|-----------------|
-| `stage_type` enum | ➕ ADD | Adopted directly: `simple`, `dynamic`, `automated` |
-| `BranchRule` struct | ➕ ADD | Adopted as `branch_rules` JSONB on `workflow_stages` |
-| Starlark hook integration | ➕ ADD | `starlark_hook` column + engine integration |
-| Graph engine (`server/engine/graph.go`) | ➕ ADD | `server/workflow/engine.go` in core |
-| Automated stage runner | ➕ ADD | `server/workflow/automated.go` in core |
-| Visual form builder (5 Preact components) | 🗑 TRASH *for now* | The form builder was tightly coupled to chat-switchboard's stage editor surface. Core doesn't ship a workflow editor surface (that's an extension). The form *schema* is kernel; the form *builder UI* is a surface package concern. Revisit when a workflow-admin surface is built. |
-| Stage type badges in UI | 🗑 TRASH | Same — UI is extension territory. |
-
-### v0.39.1 — Stage Reorder + Bulk Ops
-
-| Component | Disposition | Core equivalent |
-|-----------|-------------|-----------------|
-| Drag-and-drop reorder | 🗑 TRASH | UI concern. The kernel `ReorderStages` endpoint already exists. |
-| Bulk assignment ops | ➕ ADD (later) | Useful but not blocking. Defer to v0.2.7+. The individual claim/unclaim/cancel endpoints come first. |
-
-### v0.39.2 — SLA Alerting
-
-| Component | Disposition | Core equivalent |
-|-----------|-------------|-----------------|
-| Periodic SLA scanner | ➕ ADD | Kernel scheduled goroutine (like the existing staleness sweep). Query active instances with `sla_seconds` configured, compute breach from `stage_entered_at`. |
-| `sla_notified_at` on instances | ➕ ADD | Add to `workflow_instances` schema. Prevents duplicate notifications. |
-| Notifications on breach | ➕ ADD | Use existing `notifications` table + bus event (`workflow.sla.breached`). |
-| Webhook on breach | ➕ ADD | Fire workflow's `webhook_url` if configured. |
-| Pulsing badge animation | 🗑 TRASH | UI concern for a surface package. |
-
-### v0.39.3 — Visitor Portal
-
-| Component | Disposition | Core equivalent |
-|-----------|-------------|-----------------|
-| Public entry endpoint | ➕ ADD | `/api/v1/workflows/entry/:slug` — kernel handles anonymous session creation + token issuance. |
-| Session resume via token | ➕ ADD | `entry_token` on `workflow_instances` + `GetInstanceByToken` store method. |
-| Branded entry page | 🗑 TRASH | Surface package. The kernel stores `branding` JSONB — a portal surface reads it. |
-| Progress indicator | 🗑 TRASH | Surface package reads stage list, computes "step N of M" locally. |
-| Email notifications | 🗑 TRASH *for now* | Requires SMTP infrastructure. Defer to post-MVP or make it a connection-based extension (use ext_connections for SMTP config, fire via Starlark hook). |
-
-### v0.39.4 — Templates + Clone
-
-| Component | Disposition | Core equivalent |
-|-----------|-------------|-----------------|
-| Clone endpoint | ➕ ADD | `POST /api/v1/workflows/:id/clone` — deep copy workflow + stages. Straightforward. |
-| Built-in templates table | 🗑 TRASH | Core doesn't ship opinionated templates. Templates are workflow packages (`.pkg` archives). A "template gallery" is a surface. |
-| Template picker UI | 🗑 TRASH | Surface concern. |
-
-### v0.39.5 — Analytics

-## 13. What We're NOT Doing (Explicit Deferrals)
-
-| Item | Why | Revisit |
-|------|-----|---------|
-| Visual form builder UI | Surface concern, no workflow-admin surface yet | When a workflow-admin surface ships |
-| Drag-and-drop stage reorder UI | Surface concern | Same |

-| Bulk assignment operations | Individual ops first | v0.2.7+ |
-| Workflow chaining (`on_complete`) | Already in schema, needs engine wiring | v0.2.7 |
-| Visitor portal surface | Surface package, not kernel | Extension track |
-

-
-## 14. Migration Policy Reminder
-
-From the design-decisions log:
-
-> **No new migrations pre-MVP.** Edit existing migration SQL files in place.
-> No migration chains until schema is in production.
-
-For this redesign:
-- **`007_workflows.sql`**: Edit in place for column changes AND add new tables to the same file.
-- **No `012_*.sql`**: Everything goes in 007.
-- **Both dialects**: Postgres and SQLite must be kept in sync.
-
-The only time a new numbered migration file is created is when a truly new,
-unrelated subsystem is added (like 011_triggers.sql was for the trigger system).
-Workflow instances and assignments are part of the workflow subsystem → they go in 007.
-
----
-
-## 15. Public Surfaces — Kernel Capability, Not Workflow Feature
-
-### The problem with workflow-owned public access
-
-Chat-switchboard treated public access as a binary workflow toggle: `entry_mode: public_link`
-made the whole workflow public. But real workflows alternate audiences — internal setup →
-public-facing customer form → internal review → public confirmation page. And public access
-isn't even a workflow-only need: feedback forms, status pages, and surveys all need anonymous
-sessions without being workflows.
-
-### Per-stage audience (the v0.2.6 solution)
-
-The `audience` field on `workflow_stages` is the source of truth:
-
-| Audience | Who interacts | Auth required | Example |
-|----------|--------------|---------------|---------|
-| `team` | Authenticated team members | JWT | Internal triage, setup, review |
-| `public` | Anonymous visitors | Entry token | Customer intake form, confirmation page |
-| `system` | Nobody (automated) | N/A | API enrichment, routing decision |
-
-A single workflow freely alternates:
-
-```
-Stage 0: "Setup"           audience=team     (agent configures parameters)
-Stage 1: "Customer Form"   audience=public   (customer fills out intake)
-Stage 2: "Internal Review" audience=team     (team reviews submission)
-Stage 3: "Confirmation"    audience=public   (customer sees result)
-```
-
-The engine enforces boundaries:
-- When the instance enters a `public` stage, the visitor's token grants access. Team members
-  can also see it (they have elevated access).
-- When the instance enters a `team` stage, the visitor's view freezes. They see "being
-  processed" or whatever the portal surface shows. The token is still valid for resumption
-  when the next `public` stage arrives.
-- When the instance enters a `system` stage, nobody interacts — the automated hook fires
-  and the engine advances.
-
-### The `entry_mode` column
-
-Stays on the `workflows` table but becomes a derived convenience flag. If any stage has
-`audience = 'public'`, the workflow is public-entry eligible. The kernel can auto-compute
-this when stages are saved, or treat it as an explicit admin toggle that gates whether
-public stages are actually reachable. Either way, it's no longer the primary access control
-mechanism — `audience` on each stage is.
-
-### Platform-level public access (v0.2.7+ concern)
-
-The broader vision: public access as a **package-level manifest capability** so any surface
-(not just workflows) can serve anonymous visitors. A package declares `"public": true` in
-its manifest, and the kernel mounts a public route namespace (`/p/:package_slug/*`) with
-anonymous session middleware, token issuance, and rate limiting. Workflows consume this
-capability — they don't own it.
-
-For v0.2.6, the workflow-specific public entry routes are sufficient:
-```
-POST   /api/v1/workflows/entry/:slug          → StartPublic
-GET    /api/v1/workflows/entry/:token          → ResumePublic
-POST   /api/v1/workflows/entry/:token/advance  → AdvancePublic
-```
-
-The anonymous session management (entry_token on `workflow_instances`, IP rate limiting)
-lives in the workflow handler for now. Generalization to a platform-level `public_sessions`
-table happens when non-workflow surfaces need it.
-
-### Visitor view contract
-
-When a public stage is active, the kernel API returns only what the visitor should see:
-- The current stage's `form_template` (if mode is `form`)
-- The stage name and ordinal (for progress indicators)
-- Accumulated `stage_data` keys marked as `visitor_visible` (future: field-level ACL)
-- The `branding` JSONB from the workflow
-
-Internal stages, team assignments, review data, and other instances' data are never
-exposed through the token-authenticated endpoints. The surface package renders whatever
-the kernel returns — it doesn't need to filter.
-
----
-
-## 16. Branch Rules — Routing, Skipping, and Convergence
-
-### How branch_rules work
-
-Each stage has a `branch_rules` JSONB array. On stage completion, the engine evaluates rules
-top-to-bottom against accumulated `stage_data`. First match wins. No match → ordinal + 1.
-
-```json
-[
-  {"field": "priority", "op": "eq", "value": "urgent", "target_stage": "Emergency Review"},
-  {"field": "amount",   "op": "gt", "value": 10000,    "target_stage": "Manager Approval"},
-  {"field": "type",     "op": "in", "value": ["a","b"], "target_stage": "Fast Track"}
-]
-```
-
-`target_stage` accepts either a **stage name** (case-insensitive) or a **numeric ordinal**.
-The engine tries name resolution first, falls back to numeric. This is already implemented
-in `routing.go` → `resolveTarget()`.
-
-### Skipping stages
-
-Branch rules can target any stage, not just the next one. If a workflow has stages
-0→1→2→3→4 and stage 1's rules say `target_stage: "Stage 4"`, stages 2 and 3 are skipped
-for that instance. The engine doesn't care about gaps — it sets `current_stage` to whatever
-the rule resolved to.
-
-Linear workflows (no branch_rules on any stage) advance 0→1→2→3→4 by the ordinal + 1
-fallback. Adding a single branch rule to any stage introduces conditional skipping without
-changing the linear stages.
-
-### Convergence (diamond patterns)
-
-Two different branches can target the same downstream stage:
-
-```
-Stage 0: Intake Form
-  branch_rules: [
-    {field: "region", op: "eq", value: "US",   target_stage: "US Processing"},
-    {field: "region", op: "eq", value: "EU",   target_stage: "EU Processing"}
-  ]
-
-Stage 1: US Processing (ordinal 1)
-  branch_rules: [{field: "*", op: "exists", target_stage: "Final Review"}]
-  (always converge after processing)
-
-Stage 2: EU Processing (ordinal 2)
-  branch_rules: [{field: "*", op: "exists", target_stage: "Final Review"}]
-  (always converge after processing)
-
-Stage 3: Final Review (ordinal 3)
-  (both branches land here)
-```
-
-No special syntax needed. The routing engine doesn't track "which branch am I on" — it just
-resolves the target and moves the instance there. The accumulated `stage_data` carries
-everything downstream stages need to know about what happened upstream.
-
-### Backward jumps
-
-Branch rules can also target earlier stages (lower ordinals) for retry/correction loops.
-The cycle guard (max 10 consecutive automated stages) in `automated.go` prevents infinite
-loops for automated stages. For human-facing stages, backward jumps are intentional — the
-human breaks the cycle by submitting different data.
-
-### Operators
-
-Full set, inherited from the existing `routing.go` implementation:
-
-| Op | Description | Example |
-|----|-------------|---------|
-| `eq` | Loose equality (string comparison) | `"status" eq "approved"` |
-| `neq` | Not equal | `"status" neq "rejected"` |
-| `gt` | Greater than (numeric) | `"amount" gt 10000` |
-| `lt` | Less than (numeric) | `"amount" lt 100` |
-| `gte` | Greater or equal | `"score" gte 80` |
-| `lte` | Less or equal | `"score" lte 20` |
-| `in` | Value in array | `"category" in ["a","b","c"]` |
-| `contains` | Substring match | `"notes" contains "urgent"` |
-| `exists` | Field present in stage_data | `"approval_date" exists` |
-| `not_exists` | Field absent | `"rejection_reason" not_exists` |

+# Workflow Engine — Design
+
+The workflow engine provides multi-stage, form-driven processes with team
+validation, SLA enforcement, and public entry. Workflows are kernel primitives;
+workflow **surfaces** (admin UI, public landing pages) are extension packages.
+
+---
+
+## Core Concepts
+
+### Workflow Definition
+
+A workflow is a named process template owned by a team. Each workflow defines an
+ordered list of **stages** that instances progress through.
+
+| Field | Description |
+|-------|-------------|
+| `name` | Human-readable workflow name |
+| `slug` | URL-safe identifier (unique per scope) |
+| `scope` | Owning team or org |
+| `stages` | Ordered list of stage definitions |
+| `entry_mode` | `internal` (authenticated users) or `public_link` (landing page) |
+| `sla_hours` | Optional SLA deadline for instance completion |
+
+### Stage Types
+
+Each stage has a `mode` that determines how participants interact:
+
+| Mode | Behavior |
+|------|----------|
+| `form_only` | Structured form submission. Stage advances when form is complete. |
+| `form_chat` | Form plus threaded discussion. Useful for review with comments. |
+| `review` | Approval/rejection gate. Designated reviewers must sign off. |
+| `custom` | Delegates entirely to a surface package. Enables extension-driven UIs. |
+
+Stages declare an `assignee_mode` (individual, team, role-based) and optional
+form schemas (JSON Schema validated at submission time).
+
+### Workflow Instances
+
+An instance is a running execution of a workflow definition. It tracks:
+
+- Current stage index and overall status (`active`, `completed`, `cancelled`, `stale`)
+- Per-stage completion records with timestamps and actor IDs
+- Form data submitted at each stage
+- Assignment and claim history
+
+Instances use optimistic locking (`claimed_by` + `claimed_at`) to prevent
+concurrent stage advancement. A claim expires after a configurable timeout.
+
+---
+
+## Multi-Party Validation (Signoff Table)
+
+The `workflow_signoffs` table enables multi-party approval gates:
+
+| Column | Purpose |
+|--------|---------|
+| `instance_id` | Which instance |
+| `stage_index` | Which stage requires signoff |
+| `user_id` | Who signed |
+| `decision` | `approved` or `rejected` |
+| `comment` | Optional rationale |
+| `signed_at` | Timestamp |
+
+The engine checks signoff requirements before advancing past a `review` stage.
+Requirements are configurable: unanimous, majority, or N-of-M.
+
+---
+
+## SLA Scanner + Staleness Sweep
+
+Two periodic background jobs maintain workflow health:
+
+**SLA Scanner** — Runs on a configurable interval. Identifies instances that have
+exceeded their workflow's `sla_hours` deadline. Fires a `workflow.sla.breached`
+event (consumed by notification extensions or triggers).
+
+**Staleness Sweep** — Identifies instances that have been idle (no stage
+advancement) beyond a configurable threshold. Marks them as `stale` and fires
+`workflow.instance.stale`. Stale instances can be resumed or cancelled.
+
+Both jobs are distributed-safe: all cluster nodes run them, but operations are
+idempotent (UPDATE with WHERE guards).
+
+---
+
+## Public Entry
+
+Workflows with `entry_mode: public_link` are accessible at:
+
+```
+/w/:scope/:slug
+```
+
+The landing page renders the first stage's form without requiring authentication.
+On submission, the kernel creates an instance and stores the form data. Subsequent
+stages may require authentication depending on their assignee configuration.
+
+Public entry enables use cases like intake forms, support requests, and
+application submissions where the initiator is external.
+
+---
+
+## Extension Points
+
+- **Surface packages** provide workflow admin UIs and participant views
+- **Trigger extensions** can react to workflow events (`instance.created`,
+  `stage.advanced`, `sla.breached`, `instance.completed`)
+- **Custom stage mode** delegates rendering and advancement logic entirely to
+  an extension, enabling arbitrary UIs within a workflow stage

+# Design: PG-Backed Cluster Registry & Self-Assembling Mesh
+
+**Status:** Proposed — Pre-MVP / MVP wrap-up  
+**Author:** Jeff  
+**Date:** 2026-03-30  
+**Scope:** Kernel primitive — zero domain awareness
+
+---
+
+## Problem
+
+Switchboard-core is tightly coupled to PostgreSQL. Scaling horizontally requires instance coordination: peer discovery, health monitoring, ephemeral event routing, and (optionally) leader election. Traditional HA solutions (Raft, etcd, Consul) introduce a second consensus layer on top of PG — doubling operational complexity for a system that already has serializable transactions and LISTEN/NOTIFY.
+
+## Principle
+
+PG is already the consensus system. Use it as the sole coordinator for service discovery, health, pub/sub, and cluster state. Zero new infrastructure dependencies.
+
+---
+
+## Design
+
+### 1. Node Registry (Unlogged Table)
+
+```sql
+CREATE UNLOGGED TABLE IF NOT EXISTS node_registry (
+    node_id       TEXT PRIMARY KEY,
+    endpoint      TEXT NOT NULL,
+    seq           SERIAL,
+    registered_at TIMESTAMPTZ DEFAULT now(),
+    heartbeat     TIMESTAMPTZ DEFAULT now(),
+    stats         JSONB DEFAULT '{}'
+);
+```
+
+**Why UNLOGGED:** No WAL overhead, visible to all connections, survives session disconnect. Contents do NOT survive a PG crash — but a PG crash means all nodes are dead anyway. Clean slate on recovery is the correct behavior; all nodes re-register on restart.
+
+**Why not TEMPORARY:** PG temporary tables are session-scoped and invisible to other connections. Useless for cross-instance coordination.
+
+### 2. Node Lifecycle
+
+#### Startup
+
+```
+boot → connect PG → register self → read peer list →
+subscribe LISTEN/NOTIFY channels → open WS to clients → ready
+```
+
+```sql
+-- Self-registration (atomic, idempotent)
+INSERT INTO node_registry (node_id, endpoint)
+VALUES ($1, $2)
+ON CONFLICT (node_id) DO UPDATE
+SET endpoint = EXCLUDED.endpoint,
+    registered_at = now(),
+    heartbeat = now(),
+    stats = '{}';
+```
+
+`node_id` is generated at startup: `hostname + PID` or a UUID. Deterministic IDs enable restart-in-place without orphaned rows.
+
+#### Heartbeat Tick (every N seconds, e.g., 10s)
+
+Each node performs two operations per tick:
+
+```go
+// 1. Update own heartbeat + stats
+stats := collectStats() // see §5
+db.Exec(`UPDATE node_registry SET heartbeat = now(), stats = $2 WHERE node_id = $1`,
+    nodeID, stats)
+
+// 2. Sweep stale entries (idempotent — safe for concurrent execution)
+db.Exec(`DELETE FROM node_registry WHERE heartbeat < now() - interval '30 seconds'`)
+```
+
+The sweep is the distributed health check. Every node runs it. Multiple nodes deleting the same stale row is a no-op. No ring topology required — the sweep is the safety net that guarantees eventual cleanup regardless of which nodes are alive.
+
+#### Self-Eviction
+
+If a node's own heartbeat UPDATE returns 0 rows affected, it has been swept by a peer:
+
+```go
+result := db.Exec(`UPDATE node_registry SET heartbeat = now() WHERE node_id = $1`, nodeID)
+if result.RowsAffected() == 0 {
+    log.Error("evicted from registry, shutting down")
+    os.Exit(1)
+}
+```
+
+Kubernetes restarts the process. On boot it re-registers as a fresh node. The restart loop IS the recovery mechanism.
+
+### 3. Leaderless by Default
+
+No `role` column. No primary/replica distinction. All nodes are equal peers. PG is the sole coordinator.
+
+**If a leader is ever needed** (future use case), it's a small lift:
+
+```sql
+ALTER TABLE node_registry ADD COLUMN role TEXT DEFAULT 'peer';
+
+-- Atomic leader claim: first writer wins
+UPDATE node_registry SET role = 'primary'
+WHERE node_id = $1
+AND NOT EXISTS (SELECT 1 FROM node_registry WHERE role = 'primary');
+```
+
+No quorum, no voting, no term numbers. PG serialization handles it. But the current design intentionally avoids this — consistent with the existing pattern where scheduled tasks use first-to-mark-wins execution, not leader assignment.
+
+### 4. Realtime Event Routing (Two Tiers)
+
+#### Tier 1: Durable Events (messages, state changes)
+
+These are PG writes. Fan-out via `LISTEN/NOTIFY`:
+
+```
+User A sends message → Instance 1 writes to PG →
+pg_notify('channel:xyz', '{"type":"message","id":"..."}') →
+All instances receive → push to local WS clients subscribed to channel:xyz
+```
+
+This maps directly to the v0.5.0 `realtime.publish()` Starlark primitive. Kernel implementation is `pg_notify(channel, payload)`.
+
+#### Tier 2: Ephemeral Events (typing indicators, presence, cursor position)
+
+These NEVER hit durable storage.
+
+**Phase 1 (MVP):** Use PG LISTEN/NOTIFY for ephemeral events too.
+
+```
+User A types → Instance 1 WS handler →
+pg_notify('ephemeral:xyz', '{"type":"typing","user":"A"}') →
+Instance 2 receives → pushes to User B's WS
+Instance 3 receives → pushes to User C's WS
+```
+
+PG NOTIFY payload limit is 8KB. A typing indicator is ~60 bytes. At homelab scale (3 nodes, dozens of users) this is a non-issue. One codepath, one transport, zero new infrastructure.
+
+**Phase 2 (Post-MVP, if needed):** Direct instance-to-instance mesh for ephemeral events.
+
+- Peer endpoints are already in the registry
+- Each node dials peers discovered from the registry on startup and on peer list changes
+- Ephemeral events route over the mesh; durable events stay on PG NOTIFY
+- The `realtime.publish()` Starlark API does not change — kernel swaps the underlying transport
+
+```
+                    ┌─────────────────────────────────┐
+                    │         PG (source of truth)     │
+                    │  ┌───────────┐ ┌──────────────┐  │
+                    │  │  node_    │ │  LISTEN/     │  │
+                    │  │  registry │ │  NOTIFY      │  │
+                    │  └───────────┘ └──────────────┘  │
+                    └──────┬──────────────┬────────────┘
+                           │   durable    │
+              ┌────────────┼──────────────┼────────────┐
+              │            │              │            │
+         ┌────┴────┐  ┌───┴─────┐  ┌────┴─────┐
+         │ Node 1  │◄─┤ Node 2  ├─►│  Node 3  │
+         │ User A  │  │ User B  │  │  User C  │
+         └─────────┘  └─────────┘  └──────────┘
+              ◄──── ephemeral mesh ────►
+                   (Phase 2, if needed)
+```
+
+**Channel subscription model (Phase 1):** Broadcast and discard. Every node receives every event, checks local WebSocket subscriptions, drops if irrelevant. At 3 nodes this is the correct answer — trivial, no subscription state to sync, fully leaderless.
+
+### 5. Stats Collection & Admin Dashboard
+
+Each heartbeat tick publishes runtime stats in the `stats` JSONB column:
+
+```go
+var m runtime.MemStats
+runtime.ReadMemStats(&m)
+
+stats := map[string]any{
+    "goroutines":     runtime.NumGoroutine(),
+    "heap_alloc":     m.HeapAlloc,
+    "heap_sys":       m.HeapSys,
+    "gc_cycles":      m.NumGC,
+    "gc_pause_ns":    m.PauseNs[(m.NumGC+255)%256],
+    "uptime_sec":     time.Since(startTime).Seconds(),
+    "ws_clients":     wsHub.Count(),
+    "extensions":     sandbox.LoadedCount(),
+}
+```
+
+Admin dashboard API endpoint:
+
+```sql
+SELECT node_id, endpoint, registered_at, heartbeat, stats
+FROM node_registry
+ORDER BY seq;
+```
+
+**ICD envelope:** `{"data": [...]}` — consistent with list endpoint convention.
+
+The admin dashboard extension renders one card per node. One node = one card. Three nodes = three cards. The extension has zero awareness of clustering — it reads a list and renders it. This is the extensibility proof working as designed.
+
+Since `stats` is JSONB, future additions (mesh peer latency, extension execution counts, queue depths) require no schema migration. The dashboard extension renders whatever keys are present.
+
+### 6. Self-Assembling Mesh Properties
+
+The mesh builds itself from the registry with zero configuration:
+
+| Event | Behavior |
+|---|---|
+| Node starts | Inserts into registry → peers discover it on next heartbeat tick |
+| Node dies | Heartbeat goes stale → swept by peers → mesh shrinks |
+| Node restarts | Re-registers → peers discover it → mesh restores |
+| Scale up (K8s) | New replicas register → mesh grows automatically |
+| Scale down (K8s) | Terminated nodes go stale → swept → mesh shrinks |
+| PG crash | All nodes lose connection → all exit → K8s restarts all → clean re-registration |
+
+No config files listing peers. No seed nodes. No service discovery sidecar. No bootstrap ceremony. The registry table IS the service mesh control plane.
+
+---
+
+## What This Enables (Future)
+
+These are NOT in scope for this work. Listed to validate the design supports them without rearchitecting.
+
+- **Work distribution:** Primary (if elected) assigns extension execution shards via registry metadata. Replicas poll for assignments. No message queue.
+- **Realtime routing (v0.5.0):** When a node owns a pub/sub channel, it registers ownership in PG. Other nodes route publishes to the owner. Node dies → sweep clears routes → subscribers reconnect.
+- **Rolling deploys:** New version registers, old version's heartbeat goes stale, clean handoff with zero coordination protocol.
+- **Session affinity:** Registry tracks which node holds a user's WS connection. Targeted event delivery instead of broadcast (optimization for scale).
+
+---
+
+## Implementation Notes
+
+### Migration
+
+Pre-MVP: fold `CREATE UNLOGGED TABLE` into existing schema initialization. No new migration file needed. DB rebuild required (acceptable — no install base).
+
+### Configuration
+
+| Setting | Default | Notes |
+|---|---|---|
+| `CLUSTER_NODE_ID` | `hostname-PID` | Override for deterministic identity across restarts |
+| `CLUSTER_HEARTBEAT_INTERVAL` | `10s` | Tick frequency |
+| `CLUSTER_STALE_THRESHOLD` | `30s` | 3x heartbeat = stale |
+| `CLUSTER_ENDPOINT` | auto-detect | Advertised address for peer mesh (Phase 2) |
+
+### Single-Node Behavior
+
+When only one node is registered, the system behaves identically to pre-cluster switchboard-core. The registry has one row. LISTEN/NOTIFY delivers events back to the same instance. No special-casing required.
+
+### Health Endpoint Integration
+
+`GET /health` includes cluster status:
+
+```json
+{
+    "status": "healthy",
+    "node_id": "node-abc-1234",
+    "cluster": {
+        "size": 3,
+        "peers": ["node-def-5678", "node-ghi-9012"],
+        "heartbeat_age_ms": 2340
+    }
+}
+```
+
+Satisfies the v0.6.0 MVP health monitoring requirement.
+
+---
+
+## Rejected Alternatives
+
+| Alternative | Why rejected |
+|---|---|
+| etcd / Consul | Second consensus layer on top of PG. Doubles operational complexity for a system already tightly coupled to PG. Violates KISS. |
+| Redis pub/sub for ephemeral events | Second stateful service. Two failure domains, two connection pools, two things to monitor. PG NOTIFY handles the same job at homelab scale. |
+| Raft implementation in Go | Massive complexity for a problem PG serializable transactions already solve. |
+| Ring topology monitoring | Each node watches the one above it. Adjacent failures create blind spots. Sweep-all is simpler and has no edge cases. |
+| Leader election at startup | Unnecessary. Leaderless design with first-to-mark-wins task execution already works. Leader election is a future option, not a requirement. |

+# DESIGN — Native mTLS
+
+**Version:** v0.6.7
+**Status:** Implemented
+**Author:** Jeff / Claude session 2026-03-31
+
+---
+
+## Problem
+
+The existing `MTLSProxyProvider` assumes a TLS-terminating reverse proxy
+(Traefik, nginx, Istio) sits in front of the Go binary. Identity arrives
+via injected HTTP headers (`X-SSL-Client-CN`, etc.). The backend never
+participates in the TLS handshake.
+
+A target deployment class — systemd units + podman on bare metal or VMs —
+has no reverse proxy. All connections must be mTLS end-to-end:
+
+- **Client → server:** browser/CLI presents a user client cert
+- **Node → node:** cluster peers mutually authenticate for heartbeat,
+  realtime pub/sub, and registry sync
+
+The Go binary must terminate TLS itself and extract identity directly
+from the verified peer certificate.
+
+---
+
+## Non-Goals
+
+- Certificate revocation (CRL/OCSP). Deferred — short-lived certs +
+  restart is sufficient pre-1.0.
+- Automatic cert rotation. Operators restart the process after replacing
+  certs on disk.
+- Acting as a CA at runtime. Cert issuance is an offline operator task.
+
+---
+
+## Architecture
+
+### TLS Server Mode
+
+New config knob `TLS_MODE` with three values:
+
+| Value    | Behavior                                           |
+|----------|----------------------------------------------------|
+| `none`   | Plain HTTP. Current default. Use behind a proxy.   |
+| `server` | Server-side TLS only. No client cert required.     |
+| `mtls`   | Mutual TLS. Client cert required and verified.     |
+
+When `TLS_MODE` is `server` or `mtls`, the binary calls
+`http.Server.ListenAndServeTLS` with paths from `TLS_CERT` and `TLS_KEY`.
+
+When `TLS_MODE` is `mtls`, `tls.Config` is built with:
+
+```go
+&tls.Config{
+    ClientAuth: tls.RequireAndVerifyClientCert,
+    ClientCAs:  loadCACertPool(cfg.TLSCA),
+    MinVersion: tls.VersionTLS13,
+}
+```
+
+TLS 1.3 is the floor. No cipher suite configuration exposed — Go's
+defaults for 1.3 are non-negotiable and correct.
+
+### Auth Provider: MTLSNativeProvider
+
+Completely separate from `MTLSProxyProvider`. No shared code paths for
+cert extraction. They share only downstream helpers.
+
+```
+┌──────────────────────────────────────────────────┐
+│                   Shared helpers                  │
+│  ParseDN()  ·  FingerprintCert()  ·  ProvisionUser()  │
+└────────────────┬──────────────┬──────────────────┘
+                 │              │
+    ┌────────────┴───┐  ┌──────┴────────────┐
+    │ MTLSProxy      │  │ MTLSNative        │
+    │ Provider       │  │ Provider          │
+    │                │  │                   │
+    │ Reads headers: │  │ Reads TLS:        │
+    │ X-SSL-Client-* │  │ PeerCertificates  │
+    └────────────────┘  └───────────────────┘
+```
+
+**MTLSNativeProvider.Authenticate():**
+
+```go
+func (p *MTLSNativeProvider) Authenticate(c *gin.Context, s store.Stores) (*Result, error) {
+    if c.Request.TLS == nil || len(c.Request.TLS.PeerCertificates) == 0 {
+        return nil, ErrNoCert
+    }
+    peer := c.Request.TLS.PeerCertificates[0]
+
+    cn   := peer.Subject.CommonName       // → username
+    dn   := peer.Subject.String()         // → metadata
+    fp   := FingerprintCert(peer)         // sha256(DER) → external_id
+
+    return p.resolveOrProvision(c.Request.Context(), s, cn, dn, fp)
+}
+```
+
+`FingerprintCert` computes `sha256(cert.Raw)` hex-encoded. This is the
+stable identity anchor — certs can be reissued with the same CN but will
+get a new fingerprint, creating a new user unless the operator explicitly
+maps them.
+
+**Why Option B (two providers, not a mode switch):**
+
+The security properties differ fundamentally. The proxy provider trusts
+headers — if deployed without a proxy that strips client-injected headers,
+an attacker can forge identity by sending `X-SSL-Client-CN: admin`. The
+native provider trusts the TLS stack — identity is cryptographically
+verified before the HTTP layer runs. Mixing these behind a single
+code path with a runtime switch invites misconfiguration. Two types,
+selected at startup by `TLS_MODE`, eliminates the ambiguity.
+
+### Node-to-Node mTLS
+
+Each Armature node is both server and client:
+
+- **Server:** accepts connections from peers and user clients on its
+  listen address.
+- **Client:** dials peers for cluster registry heartbeat, realtime
+  event forwarding, and (future) distributed task coordination.
+
+When dialing a peer, the node presents its own cert:
+
+```go
+peerTLS := &tls.Config{
+    Certificates: []tls.Certificate{nodeKeypair},
+    RootCAs:      caCertPool,
+    MinVersion:   tls.VersionTLS13,
+}
+client := &http.Client{
+    Transport: &http.Transport{TLSClientConfig: peerTLS},
+}
+```
+
+Both sides verify against the same CA. A node whose cert is not signed
+by the cluster CA cannot join. This replaces any need for shared secrets
+or bearer tokens in the cluster protocol.
+
+**Interaction with cluster registry (DESIGN-cluster-registry.md):**
+
+The existing design uses LISTEN/NOTIFY over PostgreSQL for node
+discovery and an UNLOGGED `node_registry` table for heartbeat. mTLS
+does not change the discovery mechanism — it secures the HTTP transport
+between nodes once they've discovered each other. The heartbeat sweep,
+self-eviction, and leaderless-by-default properties are orthogonal.
+
+### Cert Topology
+
+```
+cluster-ca.crt / cluster-ca.key     ← generated once, lives on operator workstation
+  ├── node-1.crt + node-1.key       ← SAN: node-1.internal, 10.0.0.1
+  ├── node-2.crt + node-2.key       ← SAN: node-2.internal, 10.0.0.2
+  ├── user-jeff.crt + user-jeff.key  ← CN=jeff, client auth only
+  └── user-alice.crt + user-alice.key
+```
+
+**Node certs** carry both `ServerAuth` and `ClientAuth` extended key
+usages. SANs include the node's hostname and IP — required because
+peers may dial by either.
+
+**User certs** carry only `ClientAuth`. The CN becomes the username.
+Email can go in the Subject if desired (parsed by `ParseDN()`).
+
+The CA private key **never** touches a running node. Nodes receive only:
+`cluster-ca.crt` (for verifying peers), their own `node-N.crt`, and
+their own `node-N.key`.
+
+### Cert Provisioning Tooling
+
+A shell script (`scripts/switchboard-ca.sh`) wrapping `openssl` is the
+KISS path. No new binary, no new dependency. Three commands:
+
+```
+switchboard-ca init
+    → generates cluster-ca.crt + cluster-ca.key in ./ca/
+
+switchboard-ca issue-node --name node-1 --san "node-1.internal,10.0.0.1"
+    → generates node-1.crt + node-1.key in ./nodes/
+
+switchboard-ca issue-user --cn jeff [--email jeff@example.com]
+    → generates jeff.crt + jeff.key in ./users/
+```
+
+The script generates a proper `openssl.cnf` fragment per invocation
+with the right SANs, EKUs, and validity period (default 365 days for
+nodes, 90 days for users). All output is PEM.
+
+If we later want a Go-native tool (for cross-platform or embedding),
+it's a straightforward port — the `crypto/x509` stdlib does everything
+openssl does here.
+
+---
+
+## Config Surface
+
+```env
+# TLS mode — controls whether the binary terminates TLS
+# none:   plain HTTP (default, use behind a proxy)
+# server: TLS, no client cert required
+# mtls:   mutual TLS, client cert required
+TLS_MODE=mtls
+
+# Cert paths (required when TLS_MODE != none)
+TLS_CERT=/etc/armature/tls/node.crt
+TLS_KEY=/etc/armature/tls/node.key
+TLS_CA=/etc/armature/tls/ca.crt
+
+# Listen address (default :8080 for none, :8443 for tls/mtls)
+LISTEN_ADDR=:8443
+
+# Auth mode — when TLS_MODE=mtls, this should be mtls
+AUTH_MODE=mtls
+```
+
+`TLS_MODE` and `AUTH_MODE` are independent knobs:
+
+- `TLS_MODE=server` + `AUTH_MODE=builtin` = HTTPS with password login
+- `TLS_MODE=mtls` + `AUTH_MODE=mtls` = full mTLS identity
+- `TLS_MODE=none` + `AUTH_MODE=mtls` = proxy-terminated mTLS (existing behavior)
+
+The third combination is the current `MTLSProxyProvider` path. The
+first is useful for deployments that want encrypted transport but
+password auth (e.g., single-node with Let's Encrypt).
+
+---
+
+## Testing Strategy
+
+**Unit tests (in-process, no network):**
+
+Generate an ephemeral CA and certs using `crypto/x509` + `crypto/ecdsa`
+in `TestMain`. Tests call `MTLSNativeProvider.Authenticate()` with a
+fabricated `*http.Request` whose `TLS.PeerCertificates` is populated
+directly.
+
+- Valid cert → user provisioned, correct CN/fingerprint
+- No TLS → `ErrNoCert`
+- Empty PeerCertificates → `ErrNoCert`
+- Second call with same fingerprint → same user returned (idempotent)
+- Different CN, same fingerprint → same user (cert reissue scenario)
+
+**Integration tests (real TLS listener):**
+
+Spin up `http.Server` with `tls.Config` on localhost. Dial with
+`http.Client` using test client certs.
+
+- No client cert → TLS handshake rejected (Go returns it before handler)
+- Wrong CA → TLS handshake rejected
+- Valid cert → 200, user created
+- Expired cert → TLS handshake rejected
+
+**Node-to-node integration:**
+
+Two in-process servers with distinct node certs, same CA. Verify:
+
+- Node A can heartbeat to Node B
+- Node with wrong-CA cert cannot dial either
+- Connection refused when cert SANs don't match dial address
+  (if `tls.Config.ServerName` is set — TBD whether we enforce this
+  for internal traffic or rely solely on CA verification)
+
+---
+
+## Migration Notes
+
+No database schema changes. The `users` table already has `auth_source`
+and `external_id` columns from the v0.24.1 mTLS/OIDC work. The native
+provider populates them identically to the proxy provider.
+
+The new code is:
+
+| File | Purpose |
+|------|---------|
+| `server/auth/mtls_native.go` | `MTLSNativeProvider` type |
+| `server/auth/mtls_helpers.go` | Shared: `ParseDN`, `FingerprintCert`, `resolveOrProvision` |
+| `server/auth/mtls_native_test.go` | Unit + integration tests |
+| `server/config/tls.go` | `TLSConfig` struct, loader, validation |
+| `scripts/switchboard-ca.sh` | Cert provisioning wrapper |
+
+`server/auth/mtls.go` (existing) is renamed to `mtls_proxy.go` for
+clarity. No behavioral changes to the proxy provider.
+
+---
+
+## Open Questions
+
+1. **SAN enforcement on node-to-node:** Do we verify `ServerName`
+   matches the dialed address, or just verify the cert is CA-signed?
+   Strict SAN checking is more secure but makes IP changes painful.
+   Recommendation: verify CA signature only for internal traffic;
+   SAN checking for client-facing listen.
+
+2. **Cert rotation without restart:** Not in scope for v0.6.7, but
+   the `tls.Config.GetCertificate` / `GetConfigForClient` callbacks
+   make it straightforward to add later — read cert from disk on each
+   handshake (with caching). Worth noting in the design so we don't
+   paint ourselves into a corner.
+
+3. **PKCS#12 / combined files:** Some operators prefer `.p12` bundles
+   over separate `.crt`/`.key` files. Low priority but trivial to add
+   via `crypto/pkcs12.Decode`. Defer unless requested.

+# Distribution Guide
+
+## Quick Start
+
+```bash
+docker pull ghcr.io/switchboard-core/switchboard-core:latest
+docker run -p 8080:80 \
+  -e SWITCHBOARD_ADMIN_USERNAME=admin \
+  -e SWITCHBOARD_ADMIN_PASSWORD=changeme \
+  ghcr.io/switchboard-core/switchboard-core:latest
+```
+
+On first run, bundled packages are automatically installed — workflows, surfaces, and extensions are ready to use immediately.
+
+## Bundled Packages
+
+The production Docker image ships with pre-built packages. A **curated default set** is auto-installed on first boot; additional packages ship in the image and can be opted-in via `BUNDLED_PACKAGES`.
+
+#### Default Set (auto-installed)
+
+| Package | Type | Description |
+|---------|------|-------------|
+| notes | surface | Markdown notes with graph view |
+| chat | surface | Real-time chat surface |
+| chat-core | library | Conversations, messages, read cursors |
+| mermaid-renderer | extension | Diagram rendering |
+| schedules | surface | Cron task management UI |
+
+#### Opt-in (ship in image, require `BUNDLED_PACKAGES` to enable)
+
+| Package | Type | Description |
+|---------|------|-------------|
+| tasks | full | Kanban/list task manager with webhooks |
+| workflow-chat | extension | Chat integration for workflow stages |
+| dashboard | surface | Dashboard surface |
+| workflow-demo | surface | Interactive walkthrough with diagrams |
+| bug-report-triage | workflow | Public entry, severity routing, SLA timers |
+| content-approval | workflow | Multi-party signoff example |
+| employee-onboarding | workflow | Automated provisioning + manager signoff |
+| editor | surface | Rich markdown editor |
+| hello-dashboard | surface | Welcome/getting started surface |
+| team-activity-log | surface | Team activity feed |
+| webhook-notifier | workflow | HTTP outbound via connections + Starlark |
+| csv-table | extension | CSV table renderer |
+| diff-viewer | extension | Diff visualization |
+| git-board | surface | Git board interface |
+| gitea-client | library | Gitea API integration library |
+| js-sandbox | extension | JavaScript sandbox |
+| katex-renderer | extension | LaTeX rendering |
+| regex-tester | extension | Regex testing tool |
+| icd-test-runner | surface | E2E API test suite |
+| sdk-test-runner | surface | SDK feature test suite |
+
+### Behavior
+
+- **First boot**: Curated default packages are installed and enabled automatically.
+- **Subsequent boots**: No-op — already-installed packages are skipped.
+- **Admin uninstalls a package**: It stays uninstalled. Bundled packages are never force-reinstalled.
+- **To re-install**: Delete the package from the database, then restart the container.
+
+### Selecting Packages (Allowlist)
+
+Set `BUNDLED_PACKAGES` to control which packages are installed:
+
+```bash
+# Install ALL packages (everything in the image)
+docker run -p 8080:80 \
+  -e BUNDLED_PACKAGES="*" \
+  ghcr.io/switchboard-core/switchboard-core:latest
+
+# Install specific packages only
+docker run -p 8080:80 \
+  -e BUNDLED_PACKAGES="notes,tasks,schedules" \
+  ghcr.io/switchboard-core/switchboard-core:latest
+```
+
+Empty (default) installs the curated default set. Use `*` to install all packages. This is useful for Helm charts where different environments need different packages.
+
+### Disabling Auto-Install
+
+Set `SKIP_BUNDLED_PACKAGES=true` to prevent bundled packages from being installed:
+
+```bash
+docker run -p 8080:80 \
+  -e SKIP_BUNDLED_PACKAGES=true \
+  ghcr.io/switchboard-core/switchboard-core:latest
+```
+
+### Custom Bundle Directory
+
+Override the default bundled packages location with `BUNDLED_PACKAGES_DIR`:
+
+```bash
+docker run -p 8080:80 \
+  -e BUNDLED_PACKAGES_DIR=/custom/packages \
+  -v /host/packages:/custom/packages \
+  ghcr.io/switchboard-core/switchboard-core:latest
+```
+
+## Builder Image
+
+The builder image pre-caches Go modules and Node dependencies for faster custom builds.
+
+```bash
+docker pull ghcr.io/switchboard-core/builder:latest
+```
+
+### What It Caches
+
+- Go module cache (`go mod download` for all server dependencies)
+- Node modules for the CM6 editor bundle
+- Vendor library tarballs (marked, DOMPurify, mermaid, KaTeX)
+- Build tools (zip, Node.js runtime)
+
+### Using in Custom Builds
+
+Reference the builder image as a base stage in your Dockerfile:
+
+```dockerfile
+FROM ghcr.io/switchboard-core/builder:latest AS builder
+WORKDIR /app
+COPY server/ .
+RUN go build -ldflags="-s -w" -o /bin/switchboard .
+```
+
+### Building Locally
+
+```bash
+docker build -f Dockerfile.builder -t switchboard-builder .
+```
+
+## Custom Build Guide
+
+### Adding Custom Packages
+
+1. Create your package in `packages/your-package/` with a `manifest.json`
+2. Build all packages: `cd packages && bash build.sh all`
+3. Build the Docker image: `docker build -t my-switchboard .`
+
+The Dockerfile automatically builds all packages in the `packages/` directory and bundles them into the production image.
+
+### Removing Bundled Packages
+
+To exclude specific packages from the bundle, either:
+- Remove them from `packages/` before building
+- Set `SKIP_BUNDLED_PACKAGES=true` and install packages manually via the admin UI
+
+### Forking for Custom Builds
+
+```bash
+git clone https://github.com/switchboard-core/switchboard-core.git
+cd switchboard-core
+
+# Add/modify packages
+cp -r my-extension packages/my-extension/
+
+# Build with builder image for faster compilation
+docker build -t my-switchboard .
+```
+
+## Production Deployment
+
+### Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PORT` | `8080` | Backend API port |
+| `DB_DRIVER` | (auto) | `postgres` or `sqlite` |
+| `DATABASE_URL` | | PostgreSQL connection string |
+| `JWT_SECRET` | `dev-secret-change-me` | **Must change in production** |
+| `ENCRYPTION_KEY` | | AES-256 key for credential encryption |
+| `AUTH_MODE` | `builtin` | `builtin`, `mtls`, or `oidc` |
+| `STORAGE_BACKEND` | (auto) | `pvc` or `s3` |
+| `STORAGE_PATH` | `/data/storage` | PVC mount point |
+| `BASE_PATH` | | URL prefix (e.g. `/switchboard`) |
+| `SKIP_BUNDLED_PACKAGES` | `false` | Disable auto-install of bundled packages |
+| `BUNDLED_PACKAGES` | (empty = defaults) | `""` curated defaults, `"*"` all, or comma-separated IDs |
+| `BUNDLED_PACKAGES_DIR` | `/app/bundled-packages` | Override bundled packages location |
+| `LOG_FORMAT` | `text` | `text` or `json` |
+| `LOG_LEVEL` | `info` | `debug`, `info`, `warn`, `error` |
+
+### Database
+
+PostgreSQL is recommended for production. SQLite is suitable for single-instance evaluation.
+
+```bash
+# PostgreSQL (recommended)
+docker run -p 8080:80 \
+  -e DATABASE_URL="postgres://user:pass@host:5432/switchboard?sslmode=require" \
+  -e JWT_SECRET="$(openssl rand -hex 32)" \
+  -e ENCRYPTION_KEY="$(openssl rand -hex 32)" \
+  ghcr.io/switchboard-core/switchboard-core:latest
+
+# SQLite (evaluation only)
+docker run -p 8080:80 \
+  -e DB_DRIVER=sqlite \
+  -v switchboard-data:/data \
+  ghcr.io/switchboard-core/switchboard-core:latest
+```
+
+### Storage
+
+Object storage is required for file uploads and package asset extraction.
+
+```bash
+# PVC (auto-detected if path is writable)
+docker run -v switchboard-storage:/data/storage ...
+
+# S3-compatible (MinIO, AWS S3, Ceph)
+docker run \
+  -e STORAGE_BACKEND=s3 \
+  -e S3_BUCKET=switchboard \
+  -e S3_ENDPOINT=https://minio.corp:9000 \
+  -e S3_ACCESS_KEY=... \
+  -e S3_SECRET_KEY=... \
+  -e S3_FORCE_PATH_STYLE=true \
+  ...
+```
+
+### Kubernetes
+
+See the `k8s/` directory for example manifests. Key considerations:
+
+- Use `POSTGRES_HOST`, `POSTGRES_USER`, `POSTGRES_PASSWORD`, `POSTGRES_DB` env vars (assembled into DSN automatically)
+- Set liveness probe to `/healthz/live`, readiness probe to `/healthz/ready`
+- Mount a PVC at `/data/storage` for file storage, or configure S3
+- Set `JWT_SECRET` and `ENCRYPTION_KEY` via Kubernetes Secrets

+
+## db_tables Schema
+
+Tables are automatically namespaced as `ext_{package_id}_{table_name}`. Column types: `text`, `int`. Every table gets an auto-generated `id` primary key and `created_at` timestamp.
+
+```json
+"db_tables": {
+  "notes": {
+    "columns": {
+      "title":      "text",
+      "body":       "text",
+      "creator_id": "text",
+      "pinned":     "int"
+    },
+    "indexes": [
+      ["creator_id"],
+      ["pinned"]
+    ]
+  }
+}
+```
+
+## api_schema (OpenAPI Documentation)
+
+Extensions can optionally declare an `api_schema` array in their manifest to provide rich API documentation. Declared routes appear in Swagger UI at `/api/docs` with parameters, request bodies, and response schemas. Routes without `api_schema` entries still appear as auto-generated stubs.
+
+```json
+"api_schema": [
+  {
+    "path": "/items",
+    "method": "GET",
+    "summary": "List items",
+    "description": "Returns paginated items for the current user",
+    "params": {
+      "limit": {"type": "integer", "default": 50, "description": "Max results"},
+      "offset": {"type": "integer", "default": 0}
+    },
+    "response": {
+      "type": "object",
+      "example": {"data": [{"id": "string", "title": "string"}]}
+    }
+  },
+  {
+    "path": "/items",
+    "method": "POST",
+    "summary": "Create item",
+    "body": {
+      "title": {"type": "string", "required": true},
+      "description": {"type": "string"}
+    }
+  }
+]
+```
+
+Only `path` and `method` are required. All other fields are optional. Malformed entries are logged and skipped without blocking extension loading.
+
+## Starlark Sandbox API
+
+Starlark scripts run server-side with a CPU budget and memory ceiling. Available modules (granted per-permission by admin):
+
+| Module | Permission | API |
+|--------|-----------|-----|
+| `db` | `db.write` | `db.query(table, filters)`, `db.insert(table, row)`, `db.update(table, id, row)`, `db.delete(table, id)` |
+| `http` | `http` | `http.get(url)`, `http.post(url, body)` -- SSRF-safe, no private IPs by default |
+| `notifications` | `notifications` | `notifications.send(user_id, title, body)` |
+| `secrets` | `secrets` | `secrets.get(connection_type)` -- reads from the credential vault |
+| `api` | (implicit) | Registers HTTP routes at `/s/:slug/api/*path` |
+| `realtime` | `realtime.publish` | `realtime.publish(channel, event, data)` -- push to WebSocket clients |
+
+The sandbox cannot spawn goroutines, access the filesystem, or import arbitrary packages.
+
+## Permissions Model
+
+Extensions declare required permissions in `manifest.json`. The admin must grant each permission before the extension can use the corresponding module. Permission status is visible in Admin > Packages > Permissions.
+
+Kernel permissions for users/groups: `extension.use`, `extension.install`, `workflow.create`, `workflow.submit`, `admin.view`, `token.unlimited`.
+
+## File Structure
+
+```
+my-package/
+  manifest.json       # required
+  js/                 # browser-side JavaScript
+    index.js
+  css/                # stylesheets
+    styles.css
+  script.star         # Starlark entry point

+  assets/             # static assets
+  migrations/         # schema migration files
+```
+
+## Testing Extensions
+
+1. Build the package: `cd packages && bash build.sh my-package`
+2. Upload the `.pkg` file via Admin > Packages > Install.
+3. Grant permissions in Admin > Packages > Permissions.
+4. Enable the package.
+5. If it is a surface, navigate to its route (e.g., `/s/my-package`).
+
+Extension API routes are accessible at `/s/{slug}/api/{path}` and require an authenticated Bearer token.

+# Getting Started
+
+## Prerequisites
+
+- Docker and Docker Compose
+
+## Running with Docker Compose
+
+```bash
+docker compose up --build
+```
+
+Open [http://localhost:3000](http://localhost:3000). Default credentials: `admin` / `admin`.
+
+Data persists in the `sb_data` named volume. To reset everything:
+
+```bash
+docker compose down -v
+```
+
+## First Boot
+
+On first start, Switchboard Core will:
+
+1. Run database migrations (SQLite by default in compose).
+2. Create the admin user from `SWITCHBOARD_ADMIN_USERNAME` / `SWITCHBOARD_ADMIN_PASSWORD` env vars.
+3. Auto-install the curated default package set (notes, chat-core, dashboard, workflow demos, etc.).
+
+No manual setup steps are required.
+
+## Installing Additional Packages
+
+The Docker image ships with extra packages beyond the default set. To install them:
+
+- **Via Admin UI**: Go to `/admin` > Packages. Browse, enable, or install packages.
+- **Via environment variable**: Set `BUNDLED_PACKAGES` before starting:
+
+```bash
+# Install all bundled packages
+BUNDLED_PACKAGES="*" docker compose up --build
+
+# Install specific extras
+BUNDLED_PACKAGES="notes,tasks,schedules" docker compose up --build
+```
+
+You can also upload `.pkg` archives through the Admin > Packages page.
+
+## Key URLs
+
+| URL | Purpose |
+|-----|---------|
+| `/` | Redirects to your default surface |
+| `/admin` | Admin panel (users, packages, settings, teams) |
+| `/settings` | User settings (profile, preferences, default surface) |
+| `/welcome` | Welcome page (shown when no surfaces are installed) |
+| `/api/docs` | Interactive OpenAPI documentation |
+
+## Key Environment Variables
+
+| Variable | Default | Description |

+}
+```
+
+### Required Fields
+
+| Field | Description |
+|-------|-------------|
+| `id` | Unique kebab-case identifier |
+| `title` | Human-readable display name |
+| `type` | `surface`, `extension`, `full`, `library`, `workflow` |
+| `tier` | `browser`, `starlark`, `sidecar` |
+| `version` | Semver version string |
+
+### Optional Fields
+
+| Field | Description |
+|-------|-------------|
+| `description` | Short description |
+| `icon` | Emoji for sidebar/menu display |
+| `author` | Package author |
+| `route` | URL path for surfaces (e.g., `/s/my-package`) |
+| `auth` | `authenticated` or `public` |
+| `layout` | Surface layout mode (e.g., `single`) |
+| `permissions` | Array of required capabilities (`db.write`, `http`, `notifications`, `secrets`, `realtime.publish`) |
+| `api_routes` | Array of `{"method": "GET", "path": "/items"}` |
+| `db_tables` | Table definitions with columns and indexes |
+| `settings` | User-configurable settings with type, label, description, default |
+| `hooks` | Event bus subscription patterns |
+| `exports` | Functions exported by library packages |
+| `schema_version` | Integer for additive schema migrations |
+
+## Package Lifecycle
+
+1. **Install**: Upload a `.pkg` file via Admin > Packages or `POST /api/v1/admin/packages/install`. The kernel extracts the archive, creates database tables, and registers routes.
+
+2. **Enable**: Activate the package so its routes, hooks, and UI become available. `PUT /api/v1/admin/packages/:id/enable`.
+
+3. **Disable**: Deactivate without removing data. `PUT /api/v1/admin/packages/:id/disable`.
+
+4. **Update**: Upload a new `.pkg` with a higher semver version. Schema changes must be additive (new columns/tables only). `POST /api/v1/admin/packages/:id/update`.
+
+5. **Export**: Download the installed package as a `.pkg` archive. `GET /api/v1/admin/packages/:id/export`.
+
+6. **Delete**: Remove the package and its data. `DELETE /api/v1/admin/packages/:id`.
+
+## Bundled vs User-Installed
+
+**Bundled packages** ship inside the Docker image at `/app/bundled-packages`. On first boot, a curated default set is auto-installed. Behavior:
+
+- First boot: curated defaults are installed and enabled.
+- Subsequent boots: already-installed packages are skipped.
+- Admin uninstalls: the package stays uninstalled (never force-reinstalled).
+- Control via `BUNDLED_PACKAGES` env var: empty = defaults, `"*"` = all, or comma-separated IDs.
+
+**User-installed packages** are uploaded through the Admin UI or API. They follow the same lifecycle but are not tied to the Docker image.
+
+## Building Packages
+
+Packages are built by zipping the standard directories alongside `manifest.json`:
+
+```bash
+# Build all packages in the packages/ directory
+cd packages && bash build.sh
+
+# Build a single package
+cd packages && bash build.sh my-package
+```
+
+Output goes to `dist/my-package.pkg`.
+
+### Manual Build
+
+```bash
+cd packages/my-package
+zip -r ../../dist/my-package.pkg manifest.json js/ css/ script.star
+```
+
+The build script automatically includes whichever standard directories exist: `js/`, `css/`, `assets/`, `script.star`, `star/`, `migrations/`.
+
+### Custom Docker Image
+
+To bundle custom packages into a Docker image:
+
+1. Place your package in `packages/your-package/` with a `manifest.json`.
+2. Run `cd packages && bash build.sh all`.
+3. Build the image: `docker build -t my-switchboard .`
+
+The Dockerfile builds all packages and copies them into the bundled packages directory.

+# Package Registry
+
+The package registry lets admins browse and install packages from an external
+JSON index — a lightweight alternative to manually uploading `.pkg` files.
+
+## Registry JSON Format
+
+The registry is a static JSON file matching the `RegistryResponse` struct:
+
+```json
+{
+  "packages": [
+    {
+      "id": "notes",
+      "title": "Notes",
+      "version": "0.8.0",

+| `size`       | File size in bytes                       |
+| `updated_at` | ISO 8601 timestamp of last update        |
+
+## Configuring the Registry URL
+
+### Via Admin UI
+
+Navigate to **Admin > Settings > Package Registry** and enter the registry URL.
+
+### Via API
+
+```bash
+curl -X PUT /api/v1/admin/settings/package_registry \
+  -H "Content-Type: application/json" \
+  -d '{"value": {"url": "https://cdn.example.com/pkg/registry.json"}}'
+```
+
+## Generating a Registry
+
+Use `scripts/generate-registry.sh` to build a `registry.json` from a
+directory of `.pkg` files:
+
+```bash
+# Default: reads dist/, uses placeholder base URL
+./scripts/generate-registry.sh
+
+# Custom directory and base URL
+./scripts/generate-registry.sh ./my-packages https://cdn.example.com/pkg > registry.json
+```
+
+Requirements: `jq`, `unzip`, and `stat` (GNU or BSD).
+
+## Self-Hosting
+
+Any HTTPS-capable file server works. Upload your `.pkg` files and the
+generated `registry.json` to the same directory, then point the admin
+setting to the `registry.json` URL.
+
+Example with a static file server:
+
+```
+/var/www/packages/
+  registry.json
+  notes.pkg
+  chat.pkg
+  chat-core.pkg
+```
+
+The registry is fetched and cached for 5 minutes on each browse request.

+# Build Your First Browser Extension
+
+This tutorial walks through building a browser extension that renders custom
+code blocks, modeled on the CSV Table Viewer that ships with Switchboard.
+
+**Prerequisites:** A running Switchboard instance, a text editor, and `zip`.
+
+## Step 1: Create the Directory
+
+```sh
+mkdir -p my-extension/js
+```
+
+## Step 2: Write the Manifest
+
+Create `my-extension/manifest.json`:
+
+```json
+{
+    "id": "my-extension",
+    "title": "My Extension",
+    "version": "0.1.0",
+    "type": "extension",
+    "tier": "browser",
+    "author": "you",
+    "description": "Renders demo code blocks as styled HTML",
+    "permissions": [],
+    "settings": {}
+}
+```
+
+- **id** -- unique identifier, used as the install key
+- **type** -- `extension` for browser-only packages; `full` or `surface` for
+  packages with backend routes
+- **tier** -- `browser` for client-side JS; `starlark` for server-side scripting
+
+## Step 3: Write the Browser Script
+
+Create `my-extension/js/script.js`. Browser extensions use the IIFE pattern
+and register with the SDK through `sw.renderers`:
+
+```js
+(function () {
+    'use strict';
+
+    function register() {
+        if (!window.sw?.renderers) return;
+
+        sw.renderers.register('demo-block', {
+            type: 'block',
+            priority: 10,
+            match(lang) {
+                return (lang || '').toLowerCase() === 'demo';
+            },
+            render(lang, code, container) {
+                container.innerHTML =
+                    '<div style="padding:12px;background:var(--bg-2);' +
+                    'border:1px solid var(--border);border-radius:8px">' +
+                    '<strong>Demo:</strong> ' + code +
+                    '</div>';
+            }
+        });
+    }
+
+    if (window.sw?._sdk) {
+        register();
+    } else {
+        document.addEventListener('sw:ready', register, { once: true });
+    }
+})();
+```
+
+The IIFE wrapper keeps variables out of global scope. `sw.renderers.register`
+takes a name and an options object: `type: 'block'` targets fenced code blocks,
+`match` checks the language tag, and `render` receives the language, raw code,
+and a container element. The `sw:ready` event fires once the SDK initializes;
+if already loaded, register immediately. Use CSS variables like `var(--bg-2)`
+and `var(--border)` to follow the active theme.
+
+## Step 4: Package It
+
+```sh
+cd my-extension
+zip -r ../my-extension.pkg manifest.json js/
+```
+
+The `.pkg` format is a ZIP with `manifest.json` at the root. Optional
+directories: `js/`, `css/`, `assets/`. If working inside `packages/`, use
+the build script instead: `bash build.sh my-extension`.
+
+## Step 5: Install It
+
+```sh
+curl -X POST http://localhost:3000/api/v1/admin/packages/install \
+  -H "Authorization: Bearer <token>" \
+  -F "file=@my-extension.pkg"
+```
+
+You can also install through the Admin UI under the Packages section.
+
+## Step 6: Enable and Test
+
+1. Open the admin panel, navigate to Packages, confirm "My Extension" is enabled.
+2. Go to any markdown surface (Chat, Notes, etc.).
+3. Enter a fenced code block with the `demo` language tag.
+
+You should see styled output instead of a plain code block.
+
+## Going Further
+
+- **Add CSS** -- create a `css/` directory; stylesheets are injected automatically.
+- **Post-renderers** -- register with `type: 'post'` to run after block renderers
+  finish (the Mermaid extension uses this for async SVG rendering).
+- **Settings** -- declare a `settings` object in the manifest for admin-configurable values.
+- **Server-side logic** -- set `tier: "starlark"` and add `script.star` for
+  backend API routes and database tables.
+
+See `PACKAGE-FORMAT.md` for the full manifest spec and `EXTENSION-GUIDE.md`
+for advanced patterns.

+# Content Approval
+
+Multi-party content review with quorum signoff and revision cycle.
+
+## Features
+
+- **Multi-party signoff** — 2 approvals required (quorum)
+- **Rejection reroute** — rejection sends content back for revision
+- **Review cycle** — revision stage always routes back to review (loop)
+
+## Stage Flow
+
+```
+[draft]  →  [review]  →  [publish]
+   team       team  ↕      team
+             [revision]
+              team
+```
+
+## Review Cycle
+
+1. Author submits draft → enters review
+2. Reviewer A approves, Reviewer B rejects → routes to revision
+3. Author revises → branch rule routes back to review
+4. Both reviewers approve → advances to publish
+
+## Installation
+
+```bash
+curl -X POST $BASE/api/v1/admin/packages/install \
+  -H "Authorization: Bearer $TOKEN" \
+  -F "file=@packages/content-approval"

+# Employee Onboarding
+
+Automated employee provisioning with manager signoff and welcome notification.
+
+## Features
+
+- **Starlark automated stages** — `db.insert` for provisioning records, `notifications.send` for alerts
+- **Signoff gate** — manager approval required (role-based), rejection reroutes to start
+- **Progressive fieldsets** — Personal Info + Access Requirements
+- **ext_data tables** — `provisions` and `onboarding_log`
+
+## Stage Flow
+
+```
+[new-hire-info]  →  [provision-accounts]  →  [manager-signoff]  →  [it-setup]  →  [welcome]
+    team              automated (Starlark)      review + signoff       team         automated
+                      auto-advances             reject → stage 0                   auto-advances
+```
+
+## Prerequisites
+
+- Team must have a custom **"manager"** role (via Team Admin > Members > Team Roles)
+- At least one team member with the "manager" role assigned
+
+## Starlark Hooks
+
+- **`on_provision(ctx)`** — Inserts provisioning record into `provisions` table, notifies workflow starter
+- **`on_welcome(ctx)`** — Logs completion to `onboarding_log`, sends welcome notification
+
+## Installation
+
+```bash
+curl -X POST $BASE/api/v1/admin/packages/install \
+  -H "Authorization: Bearer $TOKEN" \
+  -F "file=@packages/employee-onboarding"
+```

+# Webhook Notifier
+
+Outbound webhook delivery with connection credentials and delivery logging.
+
+## Features
+
+- **Starlark `http.post`** — outbound HTTP with custom headers
+- **`connections.get`** — fallback to stored webhook connection credentials
+- **Delivery logging** — records URL, status code, event to `webhook_log` ext_data table
+- **Result review** — delivery status shown in final review stage
+
+## Stage Flow
+
+```
+[configure]  →  [fire-webhook]  →  [result]
+    team          automated          review
+                  (http.post)
+```
+
+## Starlark Hook
+
+- **`on_fire(ctx)`** — Posts JSON payload to webhook URL, falls back to `connections.get("webhook")`, logs delivery to `webhook_log`
+
+## Installation
+
+```bash
+curl -X POST $BASE/api/v1/admin/packages/install \
+  -H "Authorization: Bearer $TOKEN" \
+  -F "file=@packages/webhook-notifier"
+```

+# Workflow Chat Integration
+
+Creates scoped chat conversations when workflow stages require team collaboration.
+
+## Setup
+
+1. Install the `workflow-chat` and `chat-core` packages.
+2. In your workflow stage with `audience: team`, set `stage_config`:
+
+```json
+{
+  "on_advance": {
+    "package_id": "workflow-chat",
+    "entry_point": "on_advance"
+  }
+}
+```
+
+3. When the workflow advances to that stage, ensure `stage_data` includes:
+
+```json
+{
+  "title": "Bug Triage Discussion",
+  "team_members": [
+    {"id": "user-1", "display_name": "Alice"},
+    {"id": "user-2", "display_name": "Bob"}
+  ],
+  "creator_id": "user-1",
+  "creator_display_name": "Alice"
+}
+```
+
+The hook will:
+- Create a group conversation titled `"Bug Triage Discussion [abcd1234]"` (suffixed with instance ID)
+- Add all team members as participants
+- Send a system message linking to the workflow instance
+- Enrich `stage_data` with the `conversation_id`
+
+## Idempotency
+
+If `stage_data` already contains a `conversation_id`, the hook returns `None` (no-op).
