 All notable changes to Switchboard Core are documented here.

+## v0.6.1 — Backup/Restore + Documentation
+
+Operational tooling for data safety and extension authoring.
+
+### Added
+
+- **Backup/Restore**: Full-instance backup as `.swb` ZIP archive containing
+  core tables (JSONL), ext_data tables, and package assets. Stream to client
+  or save server-side. Restore wipes and rebuilds from archive. Dialect-neutral
+  (works across SQLite and Postgres).
+- **Admin backup section**: New "Backup" tab under `/admin` with create,
+  download, delete, and restore operations. Destructive restore requires
+  confirmation dialog.
+- **Documentation surface**: Builtin surface at `/docs` with sidebar navigation
+  and client-side markdown rendering. Ships with 5 documents: Getting Started,
+  Extension Guide, API Reference, Deployment, Package Format.
+- **Docs API**: `GET /api/v1/docs` lists available documents, `GET /api/v1/docs/:name`
+  returns raw markdown content. Authenticated (all users).
+- **Tests**: 6 backup handler tests + E2E script (`ci/e2e-backup-test.sh`).
+

+### v0.6.1 — Backup/Restore + Documentation

 | Step | Status | Description |
 |------|--------|-------------|
-| Backup tooling | | ext_data export/import, admin surface for backup management. |
-| Documentation site | | Extension authoring guide, API reference, deployment guide. |
+| 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`. |
+
+### v0.6.2 — Docs Polish + Dynamic OpenAPI
+
+| Step | Status | Description |
+|------|--------|-------------|
+| 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. |

+
+## 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`.
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PORT` | `8080` | Backend API port |
+| `DB_DRIVER` | auto | `postgres` or `sqlite` |
+| `DATABASE_URL` | | PostgreSQL DSN or SQLite path |
+| `JWT_SECRET` | `dev-secret-change-me` | Token signing key -- **must change** |
+| `ENCRYPTION_KEY` | | AES-256 key for credential vault |
+| `AUTH_MODE` | `builtin` | `builtin`, `mtls`, `oidc` |
+| `STORAGE_BACKEND` | auto | `pvc` or `s3` |
+| `STORAGE_PATH` | `/data/storage` | PVC mount point |
+| `BASE_PATH` | | URL prefix (e.g., `/switchboard`) |
+| `LOG_FORMAT` | `text` | `text` or `json` |
+| `LOG_LEVEL` | `info` | `debug`, `info`, `warn`, `error` |
+| `CORS_ALLOWED_ORIGINS` | | Comma-separated allowed origins |
+| `BUNDLED_PACKAGES` | (empty) | `""` defaults, `"*"` all, or comma-separated |
+| `SKIP_BUNDLED_PACKAGES` | `false` | Disable bundled package install |
+| `BUNDLED_PACKAGES_DIR` | `/app/bundled-packages` | Custom bundle directory |
+| `SWITCHBOARD_ADMIN_USERNAME` | | Bootstrap admin username |
+| `SWITCHBOARD_ADMIN_PASSWORD` | | Bootstrap admin password |
+| `SEED_USERS` | | Dev seed users (ignored in production) |
+
+### S3 Storage Variables
+
+| Variable | Description |
+|----------|-------------|
+| `S3_BUCKET` | Bucket name |
+| `S3_ENDPOINT` | Endpoint URL (for MinIO, Ceph, etc.) |
+| `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 |

+| `library` | Shared code imported by other packages via `lib.require()` |
+| `workflow` | Bundled workflow definition |
+
+## Tiers
+
+| Tier | Runs | Capabilities |
+|------|------|-------------|
+| `browser` | Client-side JS only | DOM access, SDK hooks, no server-side logic |
+| `starlark` | Sandboxed server-side | DB, HTTP, notifications, secrets, API routes, realtime |
+| `sidecar` | Separate container | Full runtime (future) |
+
+## manifest.json
+
+Every package has a `manifest.json` at its root. Example for a surface:
+
+```json
+{
+  "id": "my-surface",
+  "title": "My Surface",
+  "type": "full",
+  "tier": "starlark",
+  "version": "1.0.0",
+  "description": "A custom surface with server-side logic.",
+  "icon": "🔧",
+  "author": "you",
+  "route": "/s/my-surface",
+  "auth": "authenticated",
+  "permissions": ["db.write"],
+  "api_routes": [
+    {"method": "GET",  "path": "/items"},
+    {"method": "POST", "path": "/items"}
+  ],
+  "db_tables": {

+      "type": "string",
+      "label": "Items Per Page",
+      "description": "Number of items shown per page",
+      "default": "25"
+    }
+  }
+}
+```
+
+### Field Reference
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `id` | yes | Unique kebab-case identifier |
+| `title` | yes | Display name |
+| `type` | yes | `surface`, `extension`, `full`, `library`, `workflow` |

+
+## 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
+  star/               # additional Starlark modules
+  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 |
+|----------|---------|-------------|
+| `PORT` | `8080` | Backend API port |
+| `DB_DRIVER` | auto | `postgres` or `sqlite` |
+| `DATABASE_URL` | | PostgreSQL DSN or SQLite file path |
+| `JWT_SECRET` | `dev-secret-change-me` | **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 |
+| `SWITCHBOARD_ADMIN_USERNAME` | | Bootstrap admin username |
+| `SWITCHBOARD_ADMIN_PASSWORD` | | Bootstrap admin password |
+| `BUNDLED_PACKAGES` | (empty) | `""` = curated defaults, `"*"` = all, or comma-separated IDs |
+| `SKIP_BUNDLED_PACKAGES` | `false` | Disable auto-install entirely |
+| `LOG_LEVEL` | `info` | `debug`, `info`, `warn`, `error` |
+| `LOG_FORMAT` | `text` | `text` or `json` |
+
+## From Source
+
+```bash
+git clone <repo-url> && cd switchboard-core
+cp server/.env.example server/.env   # edit DB credentials
+cd server && go run .
+# Backend on http://localhost:8080

+# Package Format
+
+Switchboard packages are distributed as `.pkg` files -- ZIP archives with a standard internal structure.
+
+## ZIP Structure

+└── migrations/          # schema migration files
+```
+

+}
+```
+
+### 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.
