 All notable changes to Armature are documented here.
 
+## v0.8.5 — Extension Composability
+
+Extensions can now compose with each other through declared slots, UI
+contributions, and cross-package function calls. This is the last kernel
+feature before 1.0 — the platform now supports the "extensions extending
+extensions" pattern.
+
+**Manifest declarations**
+
+- Surfaces declare named `slots` in their manifest (e.g., `toolbar-actions`,
+  `note-footer`) with context documentation for extension authors.
+- Extensions declare `contributes` entries targeting `{host}:{slot}` names
+  (e.g., `notes:toolbar-actions`). Coupling is soft — install order doesn't
+  matter.
+- The kernel validates slot/contribution conventions at install time.
+
+**Backend: `lib.require()` relaxation**
+
+- `lib.require()` now works with any package that declares `exports`, not
+  just `type: "library"` packages. A full package (with surfaces, settings,
+  UI) can export callable functions for cross-package use.
+- The existing `depends` and permission model is unchanged — the called
+  function runs with the target package's permissions.
+
+**Admin slots endpoint**
+
+- `GET /api/v1/admin/slots` returns an aggregated map of all declared slots
+  across installed packages with their contributors.
+- Uninstalling a package that declares slots warns about orphaned
+  contributions in other packages.
+
+**SDK additions**
+
+- `sw.slots.renderAll(name, context)` — convenience helper for host surfaces
+  to render all components in a slot with error isolation.
+- `sw.slots.declare(name, description)` — runtime slot declaration for
+  discoverability and debugging.
+
+**Documentation**
+
+- `PACKAGE-FORMAT.md` — added `slots`, `contributes`, `depends` field docs.
+- `EXTENSION-GUIDE.md` — new "Extension Composability" section with slot
+  naming conventions, contribution patterns, and cross-package call examples.
+- `STARLARK-REFERENCE.md` — updated `lib` module to reflect exports-based
+  calling (not library-type-only).
+
+**Modified files:**
+
+- `server/sandbox/lib_module.go` — type check → exports check
+- `server/handlers/extensions.go` — composability field validation
+- `server/handlers/packages.go` — orphaned contribution warning
+- `server/main.go` — admin slots route registration
+- `src/js/sw/sdk/slots.js` — `renderAll()`, `declare()`, `declarations()`
+- `docs/PACKAGE-FORMAT.md` — slots, contributes, depends
+- `docs/EXTENSION-GUIDE.md` — composability section
+- `docs/STARLARK-REFERENCE.md` — lib module update
+- `docs/DESIGN-extension-composability.md` — status Draft → Implemented
+
+**New files:**
+
+- `server/handlers/admin_slots.go` — admin slot aggregation endpoint
+
+## v0.8.4 — Documentation Refresh + Surface Sizing Fix
+
+Eight versions of module additions (v0.7.5–v0.8.3) shipped without a
+docs pass. This release brings the public-facing guides up to date and
+fixes a CSS layout bug affecting all surfaces.
+
+**Documentation refresh**
+
+- `STARLARK-REFERENCE.md` — added `workspace` module section (5 builtins),
+  `permissions` module section, and `settings.has_capability()` documentation.
+- `EXTENSION-GUIDE.md` — added `capabilities` manifest block, `vector(N)`
+  column type, `user_permissions` and `gate_permission` manifest fields,
+  updated sandbox permissions list with v0.8.0+ additions (`files.read`,
+  `files.write`, `workspace.manage`).
+- `TUTORIAL-FIRST-EXTENSION.md` — reviewed for v0.7+ accuracy (no changes needed).
+
+**Surface sizing fix**
+
+All surfaces using the shell topbar had scroll content clipped at the
+bottom by ~44px (the topbar height). Root cause: surface containers were
+siblings of `#shell-topbar` inside `.surface-inner`, which used
+`height: 100%` without flex layout — the surface div claimed the full
+parent height, ignoring the topbar sibling.
+
+- Fix: `.surface-inner` now uses `display: flex; flex-direction: column`
+  so the topbar and surface share vertical space via flex layout.
+- All surface containers (`.surface-docs`, `.surface-admin`,
+  `.surface-settings`, `.surface-editor`, `.extension-surface`) changed
+  from `height: 100%` to `flex: 1; min-height: 0`.
+- Inline styles on `surface-team-admin` and `welcome-mount` templates
+  updated to match.
+
+**Modified files:**
+
+- `server/pages/templates/base.html` — `.surface-inner` gains flex column layout
+- `src/css/surfaces.css` — `.surface-docs`, `.surface-admin`, `.surface-settings`, `.surface-editor`
+- `src/css/extension-surface.css` — `.extension-surface`
+- `server/pages/templates/surfaces/team-admin.html` — inline style fix
+- `server/pages/templates/surfaces/welcome.html` — inline style fix
+- `docs/STARLARK-REFERENCE.md` — workspace, permissions, has_capability
+- `docs/EXTENSION-GUIDE.md` — capabilities, vector, user_permissions, gate_permission
+
+## v0.8.3 — Vector Column Type
+
+Extensions can now declare vector columns and perform similarity search.
+Three-tier progressive enhancement: native pgvector on Postgres, JSONB
+fallback without pgvector, TEXT fallback on SQLite.
+
+**Manifest: `db_tables` vector columns**
+
+- Declare `"vector(N)"` as a column type (N = dimension, 1–4096).
+- On Postgres with pgvector: native `vector(N)` type with auto-created
+  HNSW index (`vector_cosine_ops`).
+- On Postgres without pgvector: `JSONB` column.
+- On SQLite: `TEXT` column (JSON-encoded float arrays).
+
+**Starlark API**
+
+- `db.query_similar(table, column, vector=[], limit=10, filters={}, metric="cosine")`
+  — returns rows ordered by ascending cosine distance with injected `_distance` key.
+- `db.insert()` now accepts list values (serialized as JSON strings) for
+  vector column storage.
+
+**Internal**
+
+- Modified: `handlers/ext_db_schema.go` — `parseVectorDim`, `mapColType`
+  gains `hasPgvector` parameter, HNSW index creation for vector columns.
+- Modified: `sandbox/db_module.go` — `HasPgvector` in `DBModuleConfig`,
+  list support in `starlarkToGoValue`, `dbQuerySimilar` with pgvector and
+  fallback paths, `cosineDistance` helper.
+- Modified: `sandbox/runner.go` — wire `HasPgvector` from capabilities.
+- Modified: `handlers/extensions.go` — `SetCapabilities` on `ExtensionHandler`.
+- Modified: `server/main.go` — wire capabilities to extension handler.
+- Updated: `docs/STARLARK-REFERENCE.md` — vector similarity section.
+- New tests: 5 schema tests + 8 db module tests (13 total).
+
+## v0.8.2 — Capability Negotiation
+
+Extensions declare environment requirements in their manifest. The kernel
+validates at install time and exposes a runtime query for graceful degradation.
+
+**Manifest: `capabilities` block**
+
+- `capabilities.required` — array of capability names. Install is rejected
+  (HTTP 422) if any are unavailable. Rollback deletes the package row.
+- `capabilities.optional` — array of capability names. Install succeeds
+  regardless; extensions query at runtime via `settings.has_capability()`.
+
+**Detected capabilities:** `postgres`, `pgvector`, `object_storage`, `s3`,
+`workspace`.
+
+**Starlark API**
+
+- `settings.has_capability(name)` — returns `True` or `False`. Always
+  available (no permission required).
+
+**Admin API**
+
+- `GET /api/v1/admin/capabilities` — re-probes and returns current state.
+
+**Internal**
+
+- New: `handlers/capabilities.go` (detection, parsing, validation, admin handler).
+- New: `handlers/capabilities_test.go` (14 tests).
+- New: `sandbox/settings_module_test.go` (4 tests).
+- Modified: `handlers/packages.go` — replaced stub `checkCapabilities` with
+  real validation; `SetCapabilities` setter.
+- Modified: `handlers/packages_bundled.go` — bundled packages with unmet
+  required capabilities are skipped on startup.
+- Modified: `sandbox/settings_module.go` — `has_capability` builtin.
+- Modified: `sandbox/runner.go` — `capabilities` field + `SetCapabilities` setter.
+- Modified: `server/main.go` — `DetectCapabilities` at startup, wired to
+  runner and package handler, admin route registered.
+
+---
+
+## v0.8.1 — Workspace Module
+
+New `workspace` sandbox module. Managed disk directories for extensions
+that need a real filesystem (git, compilers, media tools).
+
+**workspace module (permission: `workspace.manage`)**
+
+- `workspace.create(name)` — create a workspace directory (idempotent). Returns absolute path. Enforces quota if `WORKSPACE_QUOTA_MB` > 0.
+- `workspace.path(name)` — get the absolute path of an existing workspace. Returns None if not found.
+- `workspace.list()` — list workspace names for this extension.
+- `workspace.delete(name)` — recursively remove a workspace (idempotent).
+- `workspace.usage(name)` — disk usage in bytes (10-second timeout on directory walk).
+
+**Configuration**
+
+- `WORKSPACE_ROOT` — mount point for extension workspaces (default `/data/workspaces`).
+- `WORKSPACE_QUOTA_MB` — per-extension quota in MB (default `0` = unlimited).
+
+**Internal**
+
+- New file: `sandbox/workspace_module.go`.
+- New permission constant: `ExtPermWorkspaceManage`.
+- Config: `WorkspaceRoot`, `WorkspaceQuotaMB` fields.
+- Runner wiring: `SetWorkspaceRoot()` setter, `buildModulesWithLibCtx` creates workspace module when permission granted.
+- Startup: `main.go` creates workspace root directory if writable, graceful degradation if not.
+- All directories scoped to `{WORKSPACE_ROOT}/{packageID}/{name}/`.
+- Security: name regex (`^[a-z][a-z0-9_]{0,62}$`), `filepath.Clean` + prefix check, `filepath.EvalSymlinks` for symlink escape detection.
+- 16 new tests (create, path, list, delete, usage, name validation, quota enforcement).
+
+## v0.8.0 — Files Module
+
+New `files` sandbox module. Bridges the existing ObjectStore (PVC/S3) into
+the Starlark sandbox with extension-scoped key namespacing.
+
+**files module (permissions: `files.read`, `files.write`)**
+
+- `files.put(name, content, content_type, metadata)` — store a file with optional metadata companion. Accepts string or bytes content. 50 MB default limit (configurable via `EXT_FILES_MAX_SIZE`).
+- `files.get(name)` — read a file. Returns dict with `content` (bytes), `content_type`, `size`, `metadata`. Returns None if not found.
+- `files.meta(name)` — read metadata only (no content transfer).
+- `files.list(prefix, limit)` — list files by prefix. Returns list of dicts. Filters out internal `_meta/` companions.
+- `files.delete(name)` — delete a file and its metadata companion. Idempotent.
+- `files.delete_prefix(prefix)` — delete all files under a prefix.
+- `files.exists(name)` — check existence without reading.
+
+**Internal**
+
+- New file: `sandbox/files_module.go`.
+- New permission constants: `ExtPermFilesRead`, `ExtPermFilesWrite`.
+- `ObjectStore` interface gains `List(ctx, prefix, limit)` method; implemented for PVC and S3.
+- Runner wiring: `SetObjectStore()` setter, `buildModulesWithLibCtx` creates files module when permission granted.
+- All keys scoped to `ext/{packageID}/`. Metadata stored as companion JSON at `ext/{packageID}/_meta/{name}`.
+- 16 new tests (15 files module + 1 PVC list).
+
+## v0.7.12 — Concurrent Execution Primitive
+
+New `batch` sandbox module. Enables extensions to parallelize arbitrary
+Starlark callables — including frozen library exports from `lib.require()`.
+
+**batch module (permission: `batch.exec`)**
+
+- `batch.exec(callables, timeout=10)` — runs up to 8 zero-arg callables concurrently, each in its own `starlark.Thread` with independent step budget. Returns `(results, errors)` tuple with ordered results. Per-branch timeout (1–30s, default 10).
+- Nested `batch.exec()` calls are prohibited (prevents exponential goroutine growth).
+- `lib.require()` not available inside branches — load libraries before the batch call.
+- `print()` output from branches is discarded.
+
+**Internal**
+
+- New file: `sandbox/batch_module.go`.
+- New permission constant: `ExtPermBatchExec`.
+- Runner wiring: `buildModulesWithLibCtx` creates batch module when permission granted.
+- Design doc: `docs/DESIGN-batch-exec.md`.
+- 12 new tests (parallel ordering, partial failure, timeout, cancellation, cap enforcement, nesting prevention, frozen sharing, permission gating).
+
+## v0.7.11 — Query & HTTP Ergonomics
+
+Four new Starlark sandbox builtins. No new permissions, no schema changes.
+
+**db module (permission: `db.read`)**
+
+- `db.count(table, filters={})` — returns integer count of matching rows.
+- `db.aggregate(table, column, op, filters={})` — single-value aggregation. `op` ∈ {count, sum, avg, min, max}. Returns int, float, or None.
+- `db.query_batch(queries)` — execute up to 10 query specs in a single call. Each spec supports the same parameters as `db.query`.
+
+**http module (permission: `api.http`)**
+
+- `http.batch(requests)` — concurrent HTTP dispatch of up to 10 requests. Individual failures return error response dicts (`status: 0`) rather than aborting the batch.
+
+**Internal**
+
+- Extracted `buildSelectQuery` helper from `dbQuery` for reuse by `db.query_batch`.
+- 21 new tests (14 db, 7 http).
+
+## v0.7.10 — Workflow Handoff + Assignment UI
+
+Closes the three UX gaps found during v0.7.9: public→team handoff,
+team inbox, and manual assignment. Also fixes dead system-admin bypass
+in team middleware and enriches assignment API responses.
+
+**Public Stage Handoff**
+
+- `RenderWorkflow()` detects audience mismatch (team/system stage + unauthenticated visitor) and renders "Submitted Successfully" screen with reference ID instead of showing the team-gated form.
+
+**API Response Enrichment**
+
+- `ListByTeam` and `ListMine` handlers enrich assignment records with `workflow_name`, `stage_name`, `sla_breached` by joining instance → workflow → version snapshot. Results cached per-request to avoid repeated DB hits.
+- `ListTeamInstances` returns `instanceView` with `workflow_name`, `stage_name`, `age_seconds`, `sla_breached`.
+
+**Team Middleware Fix**
+
+- `RequireTeamAdmin` / `RequireTeamMember` system-admin bypass was dead code (`c.Get("role")` never set by auth middleware). Fixed to resolve `PermSurfaceAdminAccess` via `resolveAndCachePerms`. Variadic `allStores` parameter preserves backward compatibility.
+
+**Team Workflow Inbox**
+
+- Enhanced `AssignmentsTab` in team-admin: "My Active" (claimed) and "Available" (unassigned) sections with claim/unclaim/release/work/complete actions, time-ago display, WS live updates.
+- Manual "Assign" button on unassigned rows with team member dropdown. New `POST /api/v1/assignments/:id/assign` endpoint.
+
+**Assignment Notifications**
+
+- Engine calls `notifyAssignment()` on assignment creation — notifies specific user or all team members via notification system.
+
+**SDK Gap Closure**
+
+- Added `workflowAssignments` domain (claim/unclaim/complete/cancel/assign/mine)
+- Added `teams.assignments`, `teams.workflowInstances`, `teams.cancelWorkflowInstance`
+- Fixed dead `workflows.cancel` route referencing `/channels/`
+
+**E2E Test**
+
+- `ci/e2e-workflow-handoff.sh`: public form → team review → claim → complete. Verifies audience mismatch screen, assignment creation, full lifecycle.
+
+---
+
+## v0.7.9 — Workflow Independence Audit
+
+Workflows proven independent of chat and all optional packages. Critical
+rendering bugs fixed, dead chat UI removed, deferred test debt closed.
+
+**RenderWorkflow Fix (critical)**
+
+- `RenderWorkflow()` was a stub that never loaded instance/stage data — post-start page was broken. Now loads instance by token/ID, resolves current stage, populates all template fields.
+- `WorkflowPageData` fields renamed: `ChannelID` → `EntryToken`, `ChannelTitle` → `WorkflowTitle`, `ChannelDescription` → `WorkflowDescription` (vestigial chat-era names)
+- Stage modes aligned: template uses Go constants (`form`, `review`, `delegated`, `automated`) instead of legacy `form_only`/`form_chat`
+- Dead chat UI removed: chat CSS, split layout, `sendMessage()`, fallback chat branch (~180 lines deleted from `workflow.html`)
+- Landing page mode conditionals updated to match Go constants
+- OpenAPI `stage_mode` enum corrected (4 occurrences)
+
+**Bug Fixes (found during verification)**
+
+- Entry token resolution: handler passed route param (instance ID) as entry token to JS. Fixed: resolve actual token from `inst.EntryToken` + `?token=` query param.
+- Fieldset submit guard: `submitForm()` checked `FORM_TPL.fields` but not `.fieldsets` — progressive forms silently no-op'd. Fixed: accept either.
+- Stage advance status check: JS checked `result.status === 'advanced'` but API returns `active`/`completed`. Fixed: on 200 OK with `active`, reload to render next stage.
+
+**Deferred test coverage (carried from v0.7.6)**
+
+- 17 new SQLite store tests: workflow CRUD, stages, instances, lifecycle (advance/complete/cancel/stale), team scope, API tokens, users, groups
+- `InstallPackage` decomposed from 400-line monolith into 7 private methods: `receiveUpload`, `parseAndValidateArchive`, `extractPackageAssets`, `registerPackage`, `applySchemaAndPermissions`, `resolveDependencies`, `checkCapabilities`
+- `ci/e2e-workflow-nochat.sh` — E2E test for workflow lifecycle without chat
+
+**Discovered issues (deferred to v0.7.10)**
+
+- Public→authenticated stage handoff: visitor sees auth-gated stage form instead of "submitted" screen
+- Team member pickup UI: no surface for claiming workflow instances
+- Assignment flow: no admin UI for manual instance assignment
+
+**Tests:** 17 new store tests, 1 new E2E script
+
+---
+
+## v0.7.8 — Bug Fixes & Admin Gaps
+
+- `StartBySlug` handler + `/api/v1/workflow-entry/:scope/:slug` route for landing page Start button
+- Workflow delete guard: admin endpoint rejects team-scoped workflows (403)
+- Package button cleanup: Delete hidden for bundled packages
+- Package export: `fetch()` with auth token instead of `window.open()`
+- Settings CSS: bottom padding fix for save button cutoff
+- Shared `StageForm` component between admin and team-admin; public entry URL with copy button
+
+---
+
+## v0.7.7 — API Tokens + Extension Permissions
+
+Personal access tokens (PATs) for programmatic API access, plus extension-declared
+user permissions for backend RBAC enforcement.
+
+**API Tokens (PATs)**
+
+- Migration 015: `api_tokens` table (PG + SQLite) with SHA-256 hash, prefix, JSON permissions, expiry
+- Token store interface + PG/SQLite implementations (Create, GetByHash, ListForUser, Revoke, CleanExpired, UpdateLastUsed)
+- `POST /api/v1/auth/tokens` — create token (returns plaintext once), permissions validated as subset of user's
+- `GET /api/v1/auth/tokens` — list my tokens; `DELETE /api/v1/auth/tokens/:id` — revoke
+- `POST /api/v1/admin/tokens` — create token for any user (audit logged as `admin.token.create`)
+- Auth middleware: `Bearer arm_pat_...` tokens validated alongside JWTs, user active check, fire-and-forget `last_used_at` update
+- Permission scoping: PAT permissions used directly at request time (git model — retained until revoked)
+- `auth.HashToken()` shared SHA-256 utility (replaces local `hashToken()` in auth.go)
+- Settings UI: API Tokens tab with create form, permission checkboxes, copy-once display, revoke button
+- Admin UI: "PAT" button on user rows creates tokens for any user
+- `BootstrapPAT`: `ARMATURE_BOOTSTRAP_PAT=true` env var creates admin PAT at startup, writes to `/tmp/armature-admin-pat.txt`
+- E2E smoke test: reads bootstrap PAT before falling back to login flow
+
+**Extension-Declared User Permissions**
+
+- Dynamic permission registry: `RegisterExtensionPermissions()` / `UnregisterExtensionPermissions()` with RWMutex
+- `AllPermissionsWithExtensions()` returns kernel + extension permissions; `AllPermissionsGrouped()` for admin UI
+- `user_permissions` manifest field: extensions declare user-facing permissions
+- `gate_permission` manifest field: ext_api.go checks user permission before calling `on_request`
+- `req["permissions"]` in Starlark request dict: user's effective permissions included for inline checks
+- `permissions.check(user_id, perm)` Starlark module: read-only permission check, always available (no sandbox gate)
+- Group UI: permissions grouped by source (Platform / package name) with section headings
+- Boot-time scan: `RegisterAllExtensionUserPermissions()` populates registry from active packages
+- Uninstall cleanup: `UnregisterExtensionPermissions()` called on package delete
+
+**Tests:** 10 new tests (7 handler + 3 auth registry)
+
+---
+
+## v0.7.6 — Code Hygiene + Test Coverage
+
+**Critical Fixes**
+- Removed `channels` from `allowedViews` in `db_module.go` — `ext_view_channels` does not exist; `db.view("channels")` would crash
+- Fixed 5 dead API routes in `workflow.html` — rewired to public workflow API (`/api/v1/public/workflows/`)
+- Fixed `RenderWorkflow` handler to pass route `:id` param as entry token (was reading unset `channel_id`)
+
+**Dead Code Removal**
+- Deleted `SeedTestChannel()` from `database/testhelper.go` (inserted into nonexistent channels table)
+- Removed `RunContext.ChannelID` from `sandbox/runner.go` (vestigial, unused)
+- Removed `webhook.Payload.ChannelID` field (channels no longer exist — breaking webhook JSON change)
+- Fixed stale comments in `storage.go`, `prometheus.go`, `workflow_module.go` referencing dead `/channels` paths
+
+**Migration Hygiene**
+- Added SQLite placeholder `013_cluster_registry.sql` (PG-only migration, aligns numbering)
+- Renumbered SQLite `013_test_runner_type.sql` → `014` to match PG (compat rename in `migrate.go`)
+- Documented missing migration 008 in both 009 files (merged into 007 during pre-1.0 consolidation)
+
+**Test Coverage**
+- 82 new workflow routing tests (`routing_test.go`): `ResolveNextStage`, `ResolveStageByName`, `ParseStageConfig`, `evaluateCondition` with all 10 operators
+- 10 new middleware tests (`permissions_test.go`): `RequirePermission`, `RequireAdmin`, permission caching, `RateLimiter` (allow/deny/fail-open)
+
+**Bug Fixes**
+- Removed dead Admin "Storage" tab from System category (backend endpoint preserved for future Monitoring use)
+- Fixed backup download: `sw.auth.token()` → `sw.auth._getToken()` — both "Download Backup" and server backup download now work
+
+## v0.7.5 — Headless E2E + CI Gate
+
+**CI Gating Redesign**
+- `VERSION` and `scripts/*` no longer trigger frontend/backend tests — deploy-only (pipeline v0.18.0)
+- `docs/*` changes now trigger build-and-deploy (docs are served in-app via Docs surface)
+- Path gating comment block updated to reflect corrected model
+
+**E2E Smoke Test**
+- `ci/e2e-smoke-test.sh` — authenticates as admin, discovers surfaces, runs Playwright navigation test
+- `ci/e2e-smoke-driver.js` — visits every surface, asserts shell topbar present, no JS console errors, home link works
+- Screenshot-on-failure: full-page PNG + console log saved as CI artifacts
+- Baseline screenshots captured for every surface (informational, not a gate)
+
+**CI Pipeline Integration**
+- `test-runners` stage re-enabled with broad trigger condition (BE/FE/packages/infra)
+- New `e2e-smoke` stage: boots server via docker-compose, runs Playwright smoke test, failure blocks merge
+- `docker-compose.ci.yml` gains `e2e-smoke` service (same Playwright v1.52.0 image)
+- `build-and-deploy` now depends on both `test-runners` and `e2e-smoke`
+
+**Documentation**
+- `docs/DESIGN-storage-primitives.md` — v0.8.x storage primitives design (files module, workspace module, capability negotiation, vector columns)
+- `docs/DESIGN-extension-composability.md` — v0.8.4 composability design (slots/contributes manifest fields, lib.require relaxation, SDK helpers)
+- `ROADMAP.md` expanded through v1.0: v0.8.x storage primitives, v0.9.x reference extensions, v0.10.x sidecar tier, v1.0 gate criteria, design principles, full design decisions log

-## v0.7.x — Test Infrastructure + Quality Gate
+## Planned
 
-The v0.6.x series built the kernel. v0.7.x makes it provably correct.
+### v0.9.x — Workflow Redesign
 
-A full surface audit (docs/AUDIT-surfaces.md) found 7 cross-surface issues
+Design doc: `docs/DESIGN-workflow-redesign.md`
-and 18 surface-specific issues across Settings, Admin, Team Admin, and Docs.
-Only Docs is properly built. The fix is three phases: (1) establish a shell
-contract and bring all four primary surfaces to parity, (2) build a runner
-framework for end-to-end browser tests, (3) automate those runners headlessly
-in CI.
 
-Design docs:
+The workflow system (~7,600 lines, 25+ files) was built incrementally and
-- `docs/DESIGN-shell-contract.md` — two-slot topbar, three navigation patterns, surface migrations
+has accumulated redundant concepts, buried primitives, and a read-only
-- `docs/DESIGN-surface-runners.md` — runner framework, requires declarations, headless E2E
+Starlark module. This series cleans up the debt and promotes reusable
-- `docs/AUDIT-surfaces.md` — full audit findings
+primitives before building reference extensions on top.
 
-### v0.7.0 — Shell Contract + Surface Audit + Rebrand Cleanup
+**v0.9.0 — Starlark Converter Consolidation + Snapshot Cleanup**
 
-Design doc: `docs/DESIGN-shell-contract.md`
+Three files contain near-identical Go↔Starlark converters; three copies
+of the snapshot parser exist. Consolidate into `sandbox/convert.go` and
+one exported snapshot function. Standardize on wrapped snapshot format.
 
-**Shell Infrastructure**
+**v0.9.1 — Team User Roles**
 
-| Step | Status | Description |
+Promote the buried role system to a kernel primitive. New
-|------|--------|-------------|
+`team_user_roles` table (many-to-many). Manifest `requires_roles` field.
-| Shell topbar (two-slot model) | done | Kernel injects topbar into `surface-extension` template. Two named slots: **left** (defaults to manifest title) and **center** (`flex: 1`, for tabs/pickers/search). Home link, notification bell, and user menu always present. |
+Team admin UI for role assignment. Kernel middleware `RequireRole()`.
-| Topbar customization API | done | `sw.shell.topbar.setLeft(vnode)` overrides left slot. `sw.shell.topbar.setSlot(vnode)` sets center slot. `sw.shell.topbar.setTitle(str)` shorthand for text-only left. `sw.shell.topbar.hide()` / `.show()` for full-bleed surfaces. |
+Starlark SDK: `teams.get_member_roles()`, `teams.has_role()`.
-| Kernel tab CSS | done | `.sw-topbar__tabs` and `.sw-topbar__tab` classes for consistent tab styling in the center slot. Surfaces use these for free or style their own slot content. |
-| Notification read broadcast | done | Backend emits `notification.read` and `notification.all_read` WS events. Bell listens for `.created`, `.read`, `.all_read`. Cross-surface sync without refetch. |
-| User menu reactivity | done | Emit `package.changed` (install/uninstall/enable/disable) and `auth.changed` (role/membership) WS events. UserMenu listens and re-fetches surface list. Most impactful single fix. |
-| Shell announcement global dismiss | done | Dismissed state persisted to localStorage keyed by content hash. Dismiss once, dismissed everywhere. |
 
-**Surface Migrations**
+**v0.9.2 — Package Adoption + Roles**
 
-| Step | Status | Description |
+`scope: adoptable` manifest field. When a team adopts an adoptable
-|------|--------|-------------|
+package, the package's `requires_roles` auto-populate into the team's
-| Settings → Pattern B (flat tabs) | done | Delete custom topbar + sidebar nav. 6 sections become flat tabs in topbar center slot. Content full-width. Fix Teams section: add team admin link, role display, leave action. Remove sessionStorage return URL logic. |
+role slots. Replaces `AdoptTeamWorkflow` clone mechanism.
-| Admin → Pattern C (category tabs + sidebar) | done | Delete custom `admin-topbar`. `setLeft()` for favicon + "Administration". `setSlot()` for category tabs (People / Workflows / System / Monitoring). Admin sidebar (sub-navigation) unchanged — surface-owned, below the topbar. Bell + user menu come free from shell. Delete bespoke CatIcon renderer if using standard SVGs. |
-| Team Admin → Pattern B (flat tabs) | done | Delete custom topbar + sidebar nav. 5 sections (Members / Connections / Workflows / Settings / Activity — Groups removed) become flat tabs. Content full-width. `setTitle()` for team-specific name. Remove sessionStorage return URL. Fix signoff user display (`user_id` → `sw.users.displayName()`). |
-| Team Admin: remove Groups tab | done | 37-line dead-end. Read-only "No groups" with no create/docs/link. Remove until team-scoped group management is properly designed. |
-| Docs → Pattern A (default) | done | Delete explicit Topbar import. Shell topbar auto-renders with manifest title. Docs sidebar (document list) is in content area, unaffected. |
 
-**Error Handling + UX Pass**
+**v0.9.3 — Typed Forms → SDK Primitive**
 
-| Step | Status | Description |
+Extract `TypedFormTemplate`, `FormField`, `FormFieldset`, etc. from
-|------|--------|-------------|
+`models/workflow.go` into a `forms` package. FE SDK: `sw.forms.render()`
-| Inline error states | done | Replace `catch { toast }` with inline error + retry on all list endpoints. New `.sw-inline-error` CSS primitive. Systematic pass across Settings, Admin, Team Admin. |
+and `sw.forms.validate()`. Starlark: `forms.validate()`. Any package
-| Empty state guidance | done | Every "No X" message gets one-line explanation + primary action (create button or doc link). Admin Groups, Workflows, Teams; Team Admin Workflows; Settings Notifications. |
+can declare forms, not just workflow stages.
 
-**Bug Fixes**
+**v0.9.4 — Deprecate `stage_type`, Collapse `stage_mode`**
 
-| Step | Status | Description |
+`stage_type` (simple/dynamic/automated) is redundant with `starlark_hook`
-|------|--------|-------------|
+presence. Remove from new manifests, keep parsing for backward compat.
-| evil-chat cleanup | done | ICD security tier: `finally` cleanup block + tighten `409` assertion. |
+Collapse `stage_mode` from 4 to 3 values: form / delegated / automated.
-| Workflow demo error surfacing | done | Replace silent `catch` with inline error + retry. |
+`review` was just `delegated` with signoff — signoff is independent of
-| Hello dashboard removal | done | Delete `packages/hello-dashboard/`. |
+rendering mode.
 
-**Rebrand**
+**v0.9.5 — Full Read/Write Workflow Starlark Module**
 
-| Step | Status | Description |
+Add `workflow.start()`, `workflow.advance()`, `workflow.cancel()`,
-|------|--------|-------------|
+`workflow.submit_signoff()` to the Starlark module. Extract engine
-| Light-mode icon SVG | done | New `favicon-light.svg` — square icon, transparent bg, dark node fills. Rename current `favicon-light.svg` (wordmark) to `wordmark.svg`. |
+interface to break circular import. Unlocks fully automated workflow
-| Dark-mode wordmark SVG | done | New `wordmark-dark.svg` — light text for dark backgrounds. |
+orchestration from Starlark hooks and extensions.
-| Light-mode raster assets | done | `favicon-light-32.png`, `favicon-light-256.png`. |
-| PWA manifest description | done | "Self-hosted extension platform — build, compose, and run extensions." |
-| REBRAND-SPEC.md | | Land into `docs/`. Find/replace patterns, validation checklist, asset inventory. |
-| base.html favicon swap | done | Verify theme swap works with new square light icon. |
 
-**Tests**
+**v0.9.6 — Conditional Routing → SDK Primitive**
 
-| Step | Status | Description |
+Expose `routing.evaluate(rules, data)` as a Starlark SDK function.
-|------|--------|-------------|
+Branch rules become a reusable decision engine for any extension.
-| Shell topbar renders for extensions | done | Home, left slot, center slot, bell, user menu present. |
-| Topbar API (setLeft, setSlot, hide) | done | Custom content renders. Hide removes topbar. |
-| All 4 surfaces use shell topbar | done | No double topbars. Each pattern (A/B/C) renders correctly. |
-| User menu reactive to package install | | Install → menu updates without reload. |
-| Notification bell cross-surface sync | | Dismiss on Notes → clears on Chat. |
-| Inline error on API failure | | Error + retry shown, not empty list. |
 
-### v0.7.1 — Surface Runner Framework
+**v0.9.7 — Multi-Surface Manifest + Route Resolution**
 
-Design doc: `docs/DESIGN-surface-runners.md`
+Packages can declare multiple surface routes with independent access
+controls. Kernel resolves routes per-page. Enables mixed public/auth
+pages in a single package.
 
-| Step | Status | Description |
+**v0.9.8 — Surface Access via Roles**
-|------|--------|-------------|
-| Runner framework (`sw.testing`) | done | SDK module: suite/test/assert, lifecycle hooks, structured JSON results. |
-| `requires` declarations | done | Runner manifests declare dependencies. Missing packages → clean skip. |
-| Cleanup enforcement | done | `s.track(type, id)` auto-deletes in `afterAll`. No leaked state. |
-| Warning tier | done | pass / fail / warning. No silent catch swallowing. |
-| ICD runner migration | done | Refactor to `sw.testing`. Test logic preserved. |
-| SDK runner migration | done | Refactor to `sw.testing`. Domain suites preserved. |
-| Runner registry surface | done | `/s/test-runners` — list runners, run-all, results dashboard. |
 
-### v0.7.2 — Package Runners + CI Gate
+Wire team roles (v0.9.1) into surface access declarations:
-
+`access: role:approver`. Kernel middleware checks role membership.
-| Step | Status | Description |
+Completes the workflow→package access story.
-|------|--------|-------------|
-| Notes runner | done | `requires: ["notes"]`. 3 suites (crud, folders, tags-search), 12 tests. |
-| Chat runner | done | `requires: ["chat", "chat-core"]`. 2 suites (conversations, messaging), 9 tests. |
-| Schedules runner | done | `requires: ["schedules"]`. 1 suite (crud), 5 tests. |
-| Workflow runner | done | `requires: ["content-approval"]`. 1 suite (lifecycle), 5 tests. |
-| Renderer runner | done | `requires: ["mermaid-renderer"]`. 1 suite (contract), 4 tests. |
-| Runner result API | done | `POST/GET /api/v1/admin/test-runners/results`. In-memory store, 4 Go tests. |
-| CI integration | done | `test-runners` stage in Gitea CI. Playwright driver, `wait-for-healthy.sh`. |
-| CI DinD networking fix | done | Resolve container IP via `docker inspect` — DinD port mapping doesn't expose to runner localhost. |
-
-### v0.7.3 — Extension Shell Migration
-
-Chat, Notes, and Schedules still use the old `sw.shell.Topbar` component,
-producing a double topbar (shell-injected + surface-owned). Migrate all
-three to the v0.7.0 shell contract (`sw.shell.topbar.setTitle/setSlot`),
-same pattern as the kernel surface migrations.
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Chat → shell topbar | done | Delete `<Topbar>`, use `setTitle('Chat')` + `setSlot()` for thread title/people button. |
-| Notes → shell topbar | done | Delete `<Topbar>`, use `setTitle('Notes')` + `setSlot()` for action buttons. |
-| Schedules → shell topbar | done | Delete `<Topbar>`, use `setTitle('Schedules')` + `setSlot()` for count/new button. |
-| Update package runner tests | done | Shell-topbar test suite in each runner — assert no legacy Topbar, uses shell API. |
-
-### v0.7.4 — Documentation + Deferred Surface Work
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Docs category grouping | done | Backend `Category` field on doc entries. Frontend groups sidebar by category with headings. Four categories: Getting Started, Platform, Extension Development, Operations. |
-| Permissions & Groups guide | done | RBAC model, 7 permission slugs, system/custom groups, settings cascade, extension permissions. |
-| Workflows user guide | done | Entry modes, stages, team roles, signoff gates, SLA, public forms, branch rules, Starlark hooks. |
-| Starlark Reference | done | Sandbox constraints, 10 modules with function signatures, permission gates, example hook script. |
-| Frontend JS Guide | done | Preact+htm runtime, 16 SDK modules with API reference, shell topbar patterns, CSS contract. |
-| Extension config_section docs | done | Manifest schema, backend discovery, frontend contract, example component. Added to Extension Guide. |
-| Docs content refresh | done | All 10 user-facing docs reviewed for v0.7.x accuracy: rebrand volume names, stale CSS vars, TLS_MODE env, self-hosted font notes, Architecture frontend section. |
-| Team Admin Workflows split | done | 722-line `workflows.js` split into 3 modules: `workflows.js` (router+CRUD), `workflow-editor.js` (editor+stages), `workflow-monitor.js` (assignments+monitor+signoff). |
-| Stale CSS variable fix | done | `--bg-2` references in `sw-shell.css` and `sw-primitives.css` replaced with `--bg-secondary`. |
-
-### v0.7.5 — Headless E2E + CI Gate
-
-| Step | Status | Description |
-|------|--------|-------------|
-| Playwright test harness | | `ci/e2e-surface-test.sh` — docker-compose, chromium, run-all, assert. |
-| Screenshot-on-failure | | Full-page screenshot + console log. CI artifacts. |
-| Navigation smoke test | | Playwright visits every surface. Asserts topbar, no JS errors, home link works. |
-| Visual regression baseline | | Optional screenshot diff. Not a gate — report for review. |
-| CI pipeline integration | | Enable `test-runners` stage, add `e2e-smoke` stage. Failure blocks merge. |

-## Post-v0.7.x
+### v0.10.x — Reference Extensions
 
-- **LLM participation** (`llm-bridge` extension)
+The kernel is complete. This series proves the platform by shipping
-- **Rich media extensions:** image generation, code sandbox, STT/TTS
+first-party extensions that exercise every primitive. These are

+- **Federation** — cross-instance package sharing, identity federation
+- **Package marketplace** — signing, review, discovery registry
+- **Desktop app** — Tauri wrapper for local-first deployment
+- **Offline/sync** — SQLite-first with PG sync for field deployments
+- **Multi-tenant SaaS mode** — tenant isolation at the team boundary

+
+## Design Principles
+
+| Principle | Implication |
+|-----------|-------------|
+| Extensions are the product | Chat, tasks, LLM, vector search, file sharing — all extensions. Zero kernel awareness of domain logic. |
+| Kernel stays thin | New kernel primitives require justification. If it can be an extension, it must be. |
+| Progressive enhancement | Every feature works on SQLite. PG adds performance. pgvector adds native vectors. S3 adds scalable storage. |
+| KISS-first | No unnecessary dependencies. Preact+htm (3KB), single binary, dual-DB from one codebase. |
+| Changeset discipline | Each CS independently CI-green. Design docs as implementation contracts. |
+| Pre-1.0 migration freedom | Schema changes fold into existing migrations. Post-1.0: proper versioned migrations. |

 | Single Docker image | Go binary + assets + migrations. |
 | Admin → RBAC group | Grant check replaces role check. |
 | Settings cascade | Scope auth + `user_overridable`. Two orthogonal axes. |
-| No new migrations pre-MVP | Proper versioned migrations post-MVP. |
 | Chat as extension, not kernel | Zero kernel awareness. Proves extensibility thesis. |
 | PG as consensus layer | UNLOGGED node_registry + LISTEN/NOTIFY. No etcd/Consul/Redis. |
 | Two trigger tiers | Extension-declared (full sandbox) vs user ad-hoc (restricted). |
-| Builtin package rationale | Must enhance kernel surfaces or demonstrate platform capabilities. |
+| Two-slot topbar model | Left slot (title/branding) + center slot (`flex: 1`, tabs/pickers). |
-| Two-slot topbar model | Left slot (title/branding) + center slot (`flex: 1`, tabs/pickers). Two named slots cover every navigation pattern: simple title (Pattern A), flat tabs full-width (Pattern B), category tabs + surface-owned sidebar (Pattern C). Surfaces without sub-items get full content width; surfaces with hierarchical navigation add their own sidebar below the topbar. Shell provides the stage; surface decides the theater. |
+| `db` module is the structured store | No separate KV primitive. Extensions declare tables. |
-| All four primary surfaces migrate to shell topbar | Admin was "keep custom topbar" initially. The two-slot model makes it unnecessary — category tabs fit in the center slot, sidebar is surface-owned below. One topbar implementation replaces four. Bell + user menu + reactivity come free on every surface. |
+| `files` module rides ObjectStore | No new kernel tables. Metadata as companion objects. |
-| Settings / Team Admin → flat tabs (Pattern B) | Both had thin sidebars (~140px) that consumed width without justification. 5–6 sections fit cleanly in topbar tabs. Full-width content is a better use of space for these surfaces. |
+| `workspace` for real filesystem | Flat blob store can't serve git/compilers/ffmpeg. Managed disk paths. |
-| Team Admin Groups removed | 37-line read-only dead-end. Admin Groups has full CRUD. Restore when properly designed. |
+| Capability negotiation at install | Fail loud with actionable message, not silently at runtime. |
-| Docs is the reference surface | Only surface with shell Topbar, bell, user menu, inline errors. Others converge. |
+| Vector column with three-tier fallback | Works everywhere, works fast with pgvector. |
-| Surface runners over expanding ICD | Different test tier, different failure class. |
+| Sidecar deferred to v0.11.x | HTTP module covers external APIs. Sidecars connect inward (no k8s RBAC needed). |
-| Headless E2E via Playwright | Runners produce structured JSON; Playwright navigates and reads output. |
+| Workflow redesign before reference extensions | Clean up debt and promote primitives before building on top. |

+# DESIGN — Concurrent Execution Primitive (`batch.exec`)
+
+**Version:** v0.7.12
+**Status:** Implemented
+**Author:** Jeff / Claude session 2026-04-02
+
+---
+
+## Problem
+
+Starlark is single-threaded by design (`go.starlark.net` enforces one
+thread per execution). Extensions that need to fan out — calling multiple
+external APIs, invoking several library functions, or performing independent
+I/O operations — must do so sequentially. For two `http.post()` calls
+taking 200ms each, the extension blocks for 400ms regardless of whether
+the calls are independent.
+
+The v0.7.10 `http.batch()` primitive solves the narrow case of parallel
+HTTP dispatch. But it doesn't help when the work is wrapped in library
+functions. If a `jira-client` library exposes `create_issue()` and a
+`confluence-client` library exposes `create_page()`, the extension author
+must either:
+
+1. Call them sequentially (slow), or
+2. Decompose the library calls back into raw `http.post()` parameters
+   to use `http.batch()` (defeats the purpose of having libraries).
+
+The platform needs a general-purpose concurrent execution primitive that
+works with arbitrary Starlark callables — including library exports.
+
+---
+
+## Non-Goals
+
+- **Shared mutable state between branches.** Each concurrent branch is
+  fully isolated. No channels, no mutexes, no shared dicts. If branches
+  need to coordinate, they don't belong in `batch.exec`.
+- **Unlimited concurrency.** A hard cap prevents extensions from spawning
+  unbounded goroutines. This is a fan-out primitive, not a thread pool.
+- **Automatic retry or circuit breaking.** Error handling is the caller's
+  responsibility. The kernel reports per-branch results and errors.
+- **Nested `batch.exec()`.** A callable inside `batch.exec` cannot itself
+  call `batch.exec`. This prevents exponential goroutine growth and keeps
+  the concurrency model flat.
+
+---
+
+## Key Insight: Frozen Libraries Are Thread-Safe
+
+The reason this works without exotic machinery is `lib.require()`.
+
+When a library is loaded via `lib.require()`, its exports are wrapped in
+a `starlarkstruct.FromStringDict()` — which produces a **frozen** struct.
+Frozen Starlark values are immutable and safe to read from any number of
+goroutines concurrently. This is a property of `go.starlark.net`, not
+something we enforce.
+
+The only mutable state in a Starlark execution is:
+
+1. **The `starlark.Thread` itself** — step counter, print buffer, cancel
+   channel. Each branch gets its own thread.
+2. **Module instances** — `db`, `http`, `settings`, etc. contain
+   configuration and hold references to shared Go objects (`*sql.DB`,
+   `http.Client`). Each branch gets fresh module instances, but the
+   underlying Go resources (`*sql.DB` connection pool, etc.) are already
+   designed for concurrent access.
+3. **Local variables** — thread-local by definition in Starlark.
+
+So the construction is: one new `starlark.Thread` + one new module set
+per branch, with frozen library structs shared read-only across all
+branches. This is exactly what `triggers/schedule.go` already does for
+scheduled task execution — `buildRestrictedModules` creates a fresh
+module set for each cron fire. `batch.exec` generalizes that pattern.
+
+---
+
+## API
+
+```python
+results, errors = batch.exec([
+    lambda: jira.create_issue(issue_data),
+    lambda: confluence.create_page(page_data),
+    lambda: slack.post_message(channel, msg),
+])
+
+# results[0] = return value of jira.create_issue(), or None on error
+# errors[0]  = None on success, or error string on failure
+# All three ran concurrently.
+```
+
+### Signature
+
+```
+batch.exec(callables, timeout=10) → (results: list, errors: list)
+```
+
+**Parameters:**
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `callables` | `list[callable]` | Starlark callables (lambdas, named functions, bound methods). Max length: 8. |
+| `timeout` | `int` (optional) | Per-branch timeout in seconds. Default 10. Max 30. Inherits parent context deadline if shorter. |
+
+**Returns:** A 2-tuple of equal-length lists.
+
+- `results[i]` — the return value of `callables[i]`, or `None` if it
+  errored.
+- `errors[i]` — `None` if `callables[i]` succeeded, or a string error
+  message if it failed (timeout, step limit, runtime error).
+
+**Errors (whole-call):**
+
+- `callables` is empty → error
+- `callables` length > 8 → error
+- Any element is not callable → error
+- Permission `batch.exec` not granted → error
+
+### Permission
+
+New extension permission: `batch.exec`. Declared in manifest:
+
+```json
+{
+  "permissions": ["batch.exec"]
+}
+```
+
+This is a separate permission because concurrent execution has resource
+implications (goroutines, module construction overhead). Extensions that
+don't need it shouldn't pay for it. The permission doesn't imply any
+other permissions — the branch inherits whatever modules the calling
+package already has.
+
+---
+
+## Execution Model
+
+```
+batch.exec([fn_a, fn_b, fn_c])
+    │
+    ├─── goroutine 1: Thread₁ + Modules₁ → fn_a() → result[0]
+    ├─── goroutine 2: Thread₂ + Modules₂ → fn_b() → result[1]
+    └─── goroutine 3: Thread₃ + Modules₃ → fn_c() → result[2]
+    │
+    sync.WaitGroup.Wait()
+    │
+    return (results, errors)
+```
+
+### Per-Branch Construction
+
+For each callable in the input list, the kernel:
+
+1. Creates a new `sandbox.Sandbox` with the same `Config` as the parent
+   (same `MaxSteps` limit — each branch gets its own step budget, not a
+   shared one).
+2. Calls `runner.buildModulesWithLibCtx()` with the **same** `packageID`,
+   `manifest`, and `RunContext` as the parent invocation. This produces
+   a fresh module set — new `DBModuleConfig`, new `HTTPModuleConfig`, etc.
+   — pointing at the same underlying Go resources (`*sql.DB`, etc.).
+3. The `libContext` is **shared** (read path only — cached frozen exports).
+   Library exports are immutable. The `loading` map (cycle detection) is
+   not relevant because libraries are already loaded before `batch.exec`
+   runs. If a branch triggers a new `lib.require()`, it would need its
+   own `libContext` — see Open Questions.
+4. Creates a new `starlark.Thread` with the branch's print handler,
+   step limit, and context-based cancellation.
+5. Calls `starlark.Call(thread, callable, nil, nil)` — the callable
+   is a zero-arg lambda that closes over its arguments.
+
+### Context & Cancellation
+
+Each branch gets a child context derived from the parent with the
+per-branch timeout applied:
+
+```go
+branchCtx, cancel := context.WithTimeout(parentCtx, branchTimeout)
+defer cancel()
+```
+
+If the parent context is cancelled (e.g., HTTP request timeout), all
+branches are cancelled. If one branch exceeds its timeout, only that
+branch is cancelled — others continue.
+
+### Goroutine Cap
+
+Hard limit: **8 concurrent branches.** This is enforced at the API
+boundary (list length check), not via a semaphore. Rationale:
+
+- 8 covers the real-world fan-out patterns (2-5 API calls, small batch
+  operations). Nobody needs 50 concurrent Starlark branches.
+- Each branch allocates a `starlark.Thread` + module instances. At 8
+  branches, overhead is bounded at ~8KB per thread + module construction
+  time (~50μs per module set).
+- No semaphore means no queuing surprises. You get 8, period.
+
+---
+
+## Implementation
+
+### New File: `sandbox/batch_module.go`
+
+```go
+// BuildBatchModule creates the "batch" module.
+// Requires the Runner reference for per-branch module construction.
+func BuildBatchModule(
+    ctx context.Context,
+    runner *Runner,
+    packageID string,
+    manifest map[string]any,
+    rc *RunContext,
+    lc *libContext,
+) *starlarkstruct.Module
+```
+
+The module holds a reference to the `Runner` — same pattern as
+`BuildLibModule`. It needs the runner to call `buildModulesWithLibCtx`
+for each branch.
+
+### Core Implementation Sketch
+
+```go
+func batchExec(ctx context.Context, runner *Runner, packageID string,
+    manifest map[string]any, rc *RunContext, parentLC *libContext,
+) func(*starlark.Thread, *starlark.Builtin, starlark.Tuple, []starlark.Tuple) (starlark.Value, error) {
+    return func(thread *starlark.Thread, b *starlark.Builtin,
+        args starlark.Tuple, kwargs []starlark.Tuple,
+    ) (starlark.Value, error) {
+        var callableList *starlark.List
+        var timeout int = 10
+
+        if err := starlark.UnpackArgs(b.Name(), args, kwargs,
+            "callables", &callableList,
+            "timeout?", &timeout,
+        ); err != nil {
+            return nil, err
+        }
+
+        n := callableList.Len()
+        if n == 0 {
+            return nil, fmt.Errorf("batch.exec: callables list is empty")
+        }
+        if n > 8 {
+            return nil, fmt.Errorf("batch.exec: max 8 callables, got %d", n)
+        }
+        if timeout < 1 || timeout > 30 {
+            timeout = 10
+        }
+
+        // Validate all elements are callable.
+        callables := make([]starlark.Callable, n)
+        for i := 0; i < n; i++ {
+            c, ok := callableList.Index(i).(starlark.Callable)
+            if !ok {
+                return nil, fmt.Errorf("batch.exec: element %d is %s, not callable",
+                    i, callableList.Index(i).Type())
+            }
+            callables[i] = c

+        type branchResult struct {
+            index int
+            value starlark.Value
+            err   error
+        }
+
+        results := make([]starlark.Value, n)

+                    errors[idx] = starlark.String(err.Error())
+                    return
+                }
+
+                // Fresh sandbox + thread.
+                sb := New(DefaultConfig())
+                val, _, callErr := sb.Call(branchCtx, fn, nil, nil)
+
+                if callErr != nil {
+                    results[idx] = starlark.None
+                    errors[idx] = starlark.String(callErr.Error())
+                } else {
+                    results[idx] = val
+                    errors[idx] = starlark.None
+                }
+            }(i, callable)
+        }
+
+        wg.Wait()
+
+        return starlark.Tuple{
+            starlark.NewList(results),
+            starlark.NewList(errors),
+        }, nil
+    }
+}
+```
+
+### Runner Wiring
+
+In `buildModulesWithLibCtx`, add the permission case:
+
+```go
+case models.ExtPermBatchExec:
+    // Deferred — wired after module map is complete (needs runner ref).
+    hasBatchExec = true
+```
+
+After the module map is assembled:
+
+```go
+if hasBatchExec {
+    modules["batch"] = BuildBatchModule(ctx, r, packageID, manifest, rc, lc)
+}
+```
+
+### Permission Constant
+
+In `models/permissions.go`:
+
+```go
+ExtPermBatchExec = "batch.exec"
+```
+
+Add to `AllExtensionPermissions` slice.
+
+---
+
+## Callable Closure Semantics
+
+The callables passed to `batch.exec` are typically lambdas that close
+over variables from the calling scope:
+
+```python
+issue_data = {"summary": "Review Q3 report"}
+page_data  = {"title": "Q3 Report", "body": content}
+
+results, errors = batch.exec([
+    lambda: jira.create_issue(issue_data),
+    lambda: confluence.create_page(page_data),
+])
+```
+
+The closed-over values (`issue_data`, `page_data`, `jira`, `confluence`)
+are references to Starlark values in the calling thread's scope. Two
+safety properties make this work:
+
+1. **Library exports (`jira`, `confluence`) are frozen.** They were
+   returned by `lib.require()` as `starlarkstruct.FromStringDict()` —
+   deeply immutable. Safe to read from any goroutine.
+
+2. **Dict/list arguments may be mutable**, but Starlark's execution
+   model means the calling thread is **blocked** waiting for
+   `batch.exec` to return. No concurrent mutation is possible because
+   the caller can't execute while the branches are running.
+
+This is the same safety model as Go's `sync.WaitGroup` pattern: the
+goroutine that calls `wg.Wait()` cannot proceed until all goroutines
+complete, so values passed to goroutines before `wg.Add` are safe to
+read without locks.
+
+---
+
+## Open Questions
+
+### 1. `lib.require()` Inside Branches
+
+If a callable triggers a `lib.require()` that hasn't been cached yet,
+the shared `libContext.cache` would be written from a goroutine. Options:
+
+**A. Prohibit: branches cannot call `lib.require()`.** The branch gets
+a nil `libContext`, so `lib` module is unavailable inside `batch.exec`.
+Libraries must be loaded before the batch call. Simplest, safest.
+
+**B. Per-branch `libContext` with shared read cache.** Each branch gets
+its own `libContext` whose `cache` is pre-populated from the parent's
+cache (snapshot). New loads go into the branch's local cache only.
+Slightly wasteful if two branches load the same library (loaded twice),
+but safe.
+
+**C. Mutex-protected shared `libContext`.** Add a `sync.RWMutex` to
+`libContext`. Reads use `RLock`, writes use `Lock`. Minimal overhead,
+but makes `libContext` aware of concurrency — violates its current
+assumptions.
+
+**Recommendation: Option A for v0.7.11, Option B as follow-up if needed.**
+In practice, extensions call `lib.require()` at module scope (top of
+script), not inside request handlers. The lambdas passed to `batch.exec`
+call methods on already-loaded library structs. Option A covers all
+real-world patterns.
+
+### 2. Print Output
+
+Each branch has its own print buffer (the `output strings.Builder` in
+`Sandbox.Call`). Options:
+
+**A. Discard.** Branch print output is lost. Simple, avoids interleaving.
+
+**B. Collect per-branch.** Return a third list: `(results, errors, outputs)`.
+Useful for debugging but clutters the API.
+
+**C. Merge into parent.** Append all branch output to the parent thread's
+print buffer, prefixed with branch index. Requires passing the parent's
+`outputMu` and `output` builder — invasive.
+
+**Recommendation: Option A for v0.7.11.** `print()` in Starlark is a
+debugging tool, not a production logging facility. Branch callables that
+need to report status should return structured data. If debugging demand
+emerges, Option B is a backward-compatible addition.
+
+### 3. Step Limit Scope
+
+Each branch gets its own `MaxSteps` budget (default 1M). Should the
+total across all branches be capped?
+
+**No.** The per-branch cap is sufficient. 8 branches × 1M steps = 8M
+total, which completes in under a second on any modern hardware. The
+wall-clock timeout (per-branch, max 30s) is the real resource guard.
+Adding a cross-branch step budget creates coupling between independent
+execution paths — branch A's step count shouldn't affect branch B's
+ability to complete.
+
+---
+
+## Testing
+
+| Test | Description |
+|------|-------------|
+| Parallel ordering | 3 callables with different sleep durations. Results in input order, not completion order. |
+| Partial failure | 3 callables, middle one raises error. results = [val, None, val], errors = [None, "err msg", None]. |
+| Timeout per-branch | One callable sleeps beyond timeout. Others succeed. Timed-out branch returns error. |
+| Parent cancellation | Cancel parent context mid-execution. All branches cancelled. |
+| Cap enforcement | List of 9 callables → immediate error, nothing executed. |
+| Empty list | `batch.exec([])` → error. |
+| Non-callable element | `batch.exec([1, 2])` → error, nothing executed. |
+| Permission gating | Package without `batch.exec` permission → module not available. |
+| Frozen library sharing | Two branches call same frozen library function concurrently. No race. |
+| Nested batch.exec | Callable inside batch.exec attempts batch.exec → error (module not injected in branch). |
+| db module isolation | Two branches insert into same table concurrently. Both succeed, no corruption. |
+| http module isolation | Two branches make HTTP calls with different headers. No cross-contamination. |
+
+---
+
+## Migration
+
+No schema changes. No new tables. No new migrations.
+
+New permission constant `batch.exec` added to `models/permissions.go`.
+Extensions must declare the permission in their manifest to access the
+`batch` module.

+**Version:** v0.8.5
+**Status:** Implemented

+
+## Problem
+
+Extensions cannot meaningfully compose with each other. A Notes surface
+can't accept toolbar buttons from an STT extension. An LLM bridge can't
+invoke an image generator's functions. A chat surface can't display action
+buttons contributed by an image-editing extension.
+
+The runtime primitives for contribution exist — `sw.slots`, `sw.actions`,
+and `sw.renderers` are live in the SDK. But there is no manifest layer
+to declare the relationships, no backend mechanism for non-library packages
+to call each other's exported functions, and no conventions for slot
+naming or context contracts.
+
+This blocks the entire "extensions extending extensions" pattern that
+makes the platform an ecosystem rather than a collection of packages.
+
+---
+
+## Non-Goals
+
+- Arbitrary inter-extension communication (message passing, shared memory).
+  Extensions compose through declared slots, exported functions, and events.
+- Runtime dependency injection. Dependencies are declared in manifests and
+  resolved at load time.
+- Extension sandboxing on the frontend. Browser-tier JS runs in the same
+  page context. Isolation is by convention and code review, not enforcement.
+
+---
+
+## What Already Exists
+
+Three SDK registries are live and functional:
+
+**`sw.slots`** — Named UI injection points. `register(name, {id, component, priority})`
+adds a Preact component to a named slot. `get(name)` returns sorted entries.
+Emits `slots.changed` events. Dedup by id. Priority ordering.
+
+**`sw.actions`** — Named callable actions. `register(id, {handler, label, icon})`
+exposes a function by name. `run(id, ...args)` invokes it. Cross-extension
+function calls on the frontend.
+
+**`sw.renderers`** — Block and post renderers for markdown content.
+`register(name, {type, pattern, render})`. Already used by mermaid, KaTeX,
+CSV, and diff extensions.
+
+**`lib.require()`** — Backend cross-package function calls. Starlark
+packages call exported functions from library packages with the library's
+own permission context.
+
+The gap: `sw.slots` has no manifest awareness — the admin can't see which
+extensions contribute where, install/uninstall can't warn about orphaned
+contributions. `lib.require()` is restricted to `type: "library"` packages,
+so a full package like an image generator can't export callable functions.
+There are no conventions for slot naming or context contracts.
+
+---
+
+## Architecture
+
+Three additions: manifest declarations, backend relaxation, and SDK helpers.
+
+### 1. Manifest Declarations
+
+#### Host Surfaces: `slots` Field
+
+Surfaces declare named injection points with context descriptions:
+
+```json
+{
+  "id": "notes",
+  "slots": {
+    "toolbar-actions": {
+      "description": "Toolbar action buttons",
+      "context": {
+        "noteId": "string — current note ID",
+        "getContent": "function — returns note body text",
+        "setContent": "function — replaces note body text"
+      }
+    },
+    "note-footer": {
+      "description": "Content rendered below note body",
+      "context": {
+        "noteId": "string",
+        "content": "string — rendered HTML content"
+      }
+    }
+  }
+}
+```
+
+```json
+{
+  "id": "chat",
+  "slots": {
+    "message-actions": {
+      "description": "Action buttons on individual messages",
+      "context": {
+        "messageId": "string",
+        "content": "string — message text",
+        "attachments": "array — [{url, type, name}]"
+      }
+    },
+    "image-actions": {
+      "description": "Action buttons overlaid on rendered images",
+      "context": {
+        "imageUrl": "string",
+        "messageId": "string",
+        "metadata": "object — generation params if available"
+      }
+    },
+    "composer-tools": {
+      "description": "Tool buttons in the message composer area",
+      "context": {
+        "conversationId": "string",
+        "insertText": "function — appends to composer"
+      }
+    }
+  }
+}
+```
+
+The `context` field is documentation, not enforcement. It tells extension
+authors what data the slot provides. The kernel parses and stores slot
+declarations but does not validate context shapes at runtime.
+
+#### Contributing Extensions: `contributes` Field
+
+Extensions declare which slots they inject into:
+
+```json
+{
+  "id": "note-dictate",
+  "title": "Note Dictation",
+  "type": "extension",
+  "tier": "browser",
+  "contributes": {
+    "notes:toolbar-actions": {
+      "label": "Dictate",
+      "icon": "🎤",
+      "description": "Voice-to-text note dictation"
+    }
+  },
+  "permissions": ["api.http"]
+}
+```
+
+```json
+{
+  "id": "image-gen",
+  "title": "Image Generator",
+  "type": "full",
+  "tier": "starlark",
+  "contributes": {
+    "chat:composer-tools": {
+      "label": "Generate Image",
+      "icon": "🎨",
+      "description": "AI image generation from text prompt"
+    }
+  },
+  "exports": ["generate", "list_models"],
+  "permissions": ["api.http", "connections.read", "files.write", "db.write"]
+}
+```
+
+```json
+{
+  "id": "image-edit",
+  "title": "Image Editor",
+  "type": "extension",
+  "tier": "starlark",
+  "contributes": {
+    "chat:image-actions": {
+      "label": "Edit Image",
+      "icon": "✏️",
+      "description": "Inpaint, outpaint, upscale, style transfer"
+    }
+  },
+  "exports": ["inpaint", "outpaint", "upscale", "restyle"],
+  "permissions": ["api.http", "connections.read", "files.write"]
+}
+```
+
+**Slot naming convention:** `{host-package-id}:{slot-name}`. The colon
+separates namespace from slot. Extensions contributing to `notes:toolbar-actions`
+are declaring a relationship with the `notes` package.
+
+#### What the Kernel Does with Declarations
+
+**At install time:**
+- Parse `slots` field → store in manifest (no separate table needed).
+- Parse `contributes` field → validate that each target slot name follows
+  the `{pkg}:{slot}` convention. Do NOT validate that the host package
+  exists — contributing extensions can be installed before or after their
+  host. Soft coupling.
+- Parse `exports` field → already stored in manifest. No changes needed.
+
+**At admin display time:**
+- `GET /api/v1/admin/packages/:id` includes `slots` and `contributes`
+  from manifest. Admin UI shows "This package provides X slots" and
+  "This package contributes to Y slots."
+- New endpoint: `GET /api/v1/admin/slots` → returns a map of all declared
+  slots across installed packages with their contributors. Built by
+  scanning all package manifests — no new table.
+
+**At uninstall time:**
+- If uninstalling a package that declares `slots`, check if any enabled
+  packages declare `contributes` targeting those slots. Warn (not block):
+  "Uninstalling 'notes' will orphan contributions from: note-dictate,
+  note-ai." The admin decides.
+- If uninstalling a contributing package, no warning needed — the slot
+  just has fewer entries.
+
+---
+
+### 2. Backend: `lib.require()` Relaxation
+
+Currently `lib.require()` enforces `libPkg.Type == "library"`. This
+prevents full packages (which have surfaces, settings, UI) from also
+exporting callable functions.
+
+**Change:** Replace the type check with an exports check.
+
+In `sandbox/lib_module.go`, the current guard:
+
+```go
+if libPkg.Type != "library" {
+    return nil, fmt.Errorf("lib.require: package %q is type %q, not library", libraryID, libPkg.Type)
+}
+```
+
+Becomes:
+
+```go
+exports := extractExports(libPkg.Manifest)
+if len(exports) == 0 {
+    return nil, fmt.Errorf("lib.require: package %q declares no exports", libraryID)
+}
+```
+
+Any package that declares `"exports": [...]` is callable via `lib.require()`,
+regardless of type. The dependency check (`ListByConsumer`) remains
+enforced — the consumer must still declare `"depends": ["image-gen"]`
+in its manifest.
+
+The `depends` field already accepts any package ID, not just libraries.
+The `DependencyStore` has no type check. This change is one line in
+`lib_module.go`.
+
+**Security implication:** A full package's exported functions run with
+that package's own permissions, same as libraries today. An image-gen
+package with `api.http` + `files.write` permissions exposes `generate()`
+— when llm-bridge calls it, it runs with image-gen's permissions, not
+llm-bridge's. This is correct and already how `lib.require()` works.
+
+---
+
+### 3. SDK Additions
+
+#### `sw.slots.renderAll(name, context)` Helper
+
+Currently host surfaces must manually iterate slot entries:
+
+```javascript
+const entries = sw.slots.get('notes:toolbar-actions');
+return entries.map(e => html`<${e.component} ...${ctx} />`);
+```
+
+Add a convenience helper:
+
+```javascript
+/**
+ * Render all components registered in a slot.
+ * @param {string} name — slot name
+ * @param {object} context — props passed to each component
+ * @returns {Array<VNode>} — array of rendered vnodes
+ */
+renderAll(name, context = {}) {
+    return this.get(name).map(e => {
+        try {
+            return e.component(context);
+        } catch (err) {
+            console.error(`[sw.slots] Error rendering "${e.id}" in slot "${name}":`, err);
+            return null;
+        }
+    }).filter(Boolean);
+}
+```
+
+Host surface usage becomes:
+
+```javascript
+// In Notes toolbar:
+html`<div class="notes-toolbar">
+    <button onclick=${save}>Save</button>
+    ${sw.slots.renderAll('notes:toolbar-actions', {
+        noteId: currentNote.id,
+        getContent: () => editor.getValue(),
+        setContent: (text) => editor.setValue(text)
+    })}
+</div>`
+```
+
+#### `sw.slots.declare(name, description)` (Optional)
+
+Runtime declaration for slots that don't appear in the manifest (e.g.,
+dynamically created slots). Mostly for discoverability — the debug panel
+can list all active slots whether manifest-declared or runtime-declared.
+
+```javascript
+// In chat surface, when rendering an image:
+sw.slots.declare('chat:image-actions', 'Action buttons on images');
+```
+
+Not enforced — `sw.slots.register()` works on any name regardless.
+This is a documentation/debugging aid only.
+
+---
+
+## Composition Patterns
+
+### Pattern A: LLM Tool Registration
+
+LLM bridge exposes a tool registry. Tool extensions register at load time
+via `lib.require()` on the backend and `sw.actions` on the frontend.
+
+**llm-bridge (library) — script.star:**
+```python
+_tools = {}
+
+def register_tool(name, description, parameters, handler):
+    """Register a callable tool for LLM function calling."""
+    _tools[name] = {
+        "name": name,
+        "description": description,
+        "parameters": parameters,
+        "handler": handler,
+    }
+
+def complete(messages, tools=None):
+    """Send messages to LLM with registered tools available."""
+    tool_schemas = []
+    for t in _tools.values():
+        tool_schemas.append({
+            "name": t["name"],
+            "description": t["description"],
+            "parameters": t["parameters"],
+        })
+    # ... call LLM API with tool_schemas, handle tool_use responses
+    # by dispatching to _tools[name]["handler"]
+```
+
+**image-gen (full package) — script.star:**
+```python
+llm = lib.require("llm-bridge")
+
+def generate(prompt, model="dall-e-3", size="1024x1024", seed=None):
+    conn = connections.get("openai")
+    # ... call API, store result in files module ...
+    return {"image_url": url, "prompt": prompt, "seed": actual_seed}
+
+# Register as LLM tool at load time
+llm.register_tool(
+    name="generate_image",
+    description="Generate an image from a text description",
+    parameters={"prompt": "string", "size": "string"},
+    handler=generate,
+)
+```
+
+### Pattern B: UI Contribution (Toolbar Buttons)
+
+**note-dictate (extension) — js/index.js:**
+```javascript
+sw.slots.register('notes:toolbar-actions', {
+    id: 'note-dictate',
+    priority: 200,
+    component: ({ noteId, setContent, getContent }) => {
+        const [recording, setRecording] = preact.useState(false);
+
+        const toggle = async () => {
+            if (recording) {
+                // Stop recording, send audio to STT api_route
+                const text = await sw.api.ext('note-dictate').post('/transcribe', {
+                    audio: audioBlob
+                });
+                setContent(getContent() + '\n' + text.transcription);
+                setRecording(false);
+            } else {
+                // Start recording
+                setRecording(true);
+            }
+        };
+
+        return html`<button class="sw-btn sw-btn--ghost"
+                            onclick=${toggle}
+                            title="Dictate">
+            ${recording ? '⏹' : '🎤'}
+        </button>`;
+    }
+});
+```
+
+**notes (surface) — toolbar rendering:**
+```javascript
+html`<div class="notes-toolbar__actions">
+    <button onclick=${() => saveNote()}>💾</button>
+    <button onclick=${() => togglePin()}>📌</button>
+    ${sw.slots.renderAll('notes:toolbar-actions', {
+        noteId: note.id,
+        getContent: () => editor.getValue(),
+        setContent: (text) => editor.setValue(text),
+    })}
+</div>`
+```
+
+Notes doesn't know dictation exists. Dictation doesn't know Notes'
+internals — just the slot contract (noteId, getContent, setContent).
+
+### Pattern C: Image Actions (Generate + Edit + Upscale)
+
+Three independent extensions contribute to the same image display slot:
+
+**chat surface — image rendering:**
+```javascript
+function ChatImage({ src, messageId, metadata }) {
+    return html`<div class="chat-image">
+        <img src=${src} />
+        <div class="chat-image__actions">
+            ${sw.slots.renderAll('chat:image-actions', {
+                imageUrl: src,
+                messageId,
+                metadata,
+            })}
+        </div>
+    </div>`;
+}
+```
+
+**image-gen — contributes regen button:**
+```javascript
+sw.slots.register('chat:image-actions', {

+            // Open prompt editor with original params
+            const params = await sw.prompt('Edit prompt', {
+                default: metadata?.prompt || '',
+                multiline: true,
+            });
+            if (!params) return;

+                prompt: params,
+                seed: metadata?.seed,
+                negative_prompt: metadata?.negative_prompt,
+            });
+            // result triggers a new chat message with the generated image
+        };
+
+        return html`<button class="sw-btn sw-btn--sm" onclick=${regen} title="Regenerate">
+            🔄
+        </button>`;
+    }
+});
+```
+
+**image-edit — contributes edit drawer:**
+```javascript
+sw.slots.register('chat:image-actions', {
+    id: 'image-edit:edit',
+    priority: 200,
+    component: ({ imageUrl, metadata }) => {
+        const openEditor = () => {
+            // Open a drawer with editing options
+            sw.emit('drawer.open', {
+                title: 'Edit Image',
+                component: ImageEditPanel,
+                props: { imageUrl, metadata },
+            });
+        };
+
+        return html`<button class="sw-btn sw-btn--sm" onclick=${openEditor} title="Edit">
+            ✏️
+        </button>`;
+    }
+});
+```
+
+**image-upscale — contributes upscale button:**
+```javascript
+sw.slots.register('chat:image-actions', {
+    id: 'image-upscale:upscale',
+    priority: 300,
+    component: ({ imageUrl }) => {
+        const upscale = async () => {
+            const result = await sw.api.ext('image-upscale').post('/upscale', {
+                image_url: imageUrl,
+                scale: 2,
+            });
+            // Display or replace with upscaled image
+        };
+
+        return html`<button class="sw-btn sw-btn--sm" onclick=${upscale} title="Upscale 2×">
+            🔍
+        </button>`;
+    }
+});
+```
+
+Result: an image in chat gets three action buttons from three separate
+extensions. Install one, get one button. Install all three, get all three.
+Uninstall one, the others keep working. The chat surface has no knowledge
+of any of them.
+
+### Pattern D: LLM Note Restructuring
+
+Combines backend composability (lib.require) with frontend contribution
+(slots):
+
+**note-ai (extension) — manifest.json:**
+```json
+{
+  "id": "note-ai",
+  "type": "extension",
+  "tier": "starlark",
+  "depends": ["llm-bridge"],
+  "contributes": {
+    "notes:toolbar-actions": {
+      "label": "AI Restructure",
+      "icon": "✨"
+    }
+  },
+  "permissions": ["api.http"],
+  "settings": {
+    "restructure_prompt": {
+      "type": "string",
+      "label": "Restructure Prompt",
+      "description": "System prompt for AI note restructuring",
+      "default": "Restructure the following note into clear sections with headers. Preserve all information. Use markdown formatting.",
+      "user_overridable": true
+    }
+  }
+}
+```
+
+**note-ai — script.star (api_route handler):**
+```python
+llm = lib.require("llm-bridge")
+
+def on_request(req):
+    if req["method"] == "POST" and req["path"] == "/restructure":
+        content = req["body"]["content"]
+        prompt = settings.get("restructure_prompt")
+        result = llm.complete([
+            {"role": "system", "content": prompt},
+            {"role": "user", "content": content},
+        ])
+        return {"status": 200, "body": {"restructured": result["text"]}}
+```
+
+**note-ai — js/index.js:**
+```javascript
+sw.slots.register('notes:toolbar-actions', {
+    id: 'note-ai:restructure',
+    priority: 500,
+    component: ({ noteId, getContent, setContent }) => {
+        const [loading, setLoading] = preact.useState(false);
+
+        const restructure = async () => {
+            setLoading(true);
+            try {
+                const result = await sw.api.ext('note-ai').post('/restructure', {
+                    content: getContent()
+                });
+                setContent(result.restructured);
+                sw.toast('Note restructured', 'success');
+            } catch (e) {
+                sw.toast('Restructure failed: ' + e.message, 'error');
+            } finally {
+                setLoading(false);
+            }
+        };
+
+        return html`<button class="sw-btn sw-btn--ghost"
+                            onclick=${restructure}
+                            disabled=${loading}
+                            title="AI Restructure">
+            ${loading ? '⏳' : '✨'}
+        </button>`;
+    }
+});
+```
+
+The user configures their restructuring prompt in Settings. The button
+appears in Notes toolbar. Clicking it sends the note content to the
+api_route, which calls llm-bridge, which calls the configured LLM provider.
+Four packages involved (notes, note-ai, llm-bridge, the LLM connection),
+zero hardcoded dependencies between surfaces.

+
+## Kernel Changes
+
+### Modified Files
+
+| File | Change |
+|------|--------|
+| `sandbox/lib_module.go` | Replace type check with exports check (~1 line) |
+| `handlers/extensions.go` | Parse `contributes` and `slots` manifest fields (validation) |
+| `handlers/packages.go` | Uninstall warning for orphaned contributions |
+| `src/js/sw/sdk/slots.js` | Add `renderAll(name, context)` and `declare(name, desc)` |
+| `docs/PACKAGE-FORMAT.md` | Document `slots`, `contributes`, `exports` fields |
+| `docs/EXTENSION-GUIDE.md` | Composability patterns section |
+
+### New Files
+
+| File | Purpose |
+|------|---------|
+| `handlers/admin_slots.go` | `GET /admin/slots` aggregation endpoint |
+
+### No New:
+
+- Database tables
+- Migrations
+- Starlark modules
+- Permission constants
+- Config env vars
+
+This is deliberately small. The runtime infrastructure exists. The
+design adds manifest-level visibility, one backend guard relaxation,
+and one SDK helper. The composability comes from conventions and
+documentation, not kernel complexity.
+
+---
+
+## Slot Catalog (Initial)
+
+These are the recommended slots for first-party packages. Extension
+authors may define additional slots following the naming convention.
+
+| Slot | Host | Context | Use Case |
+|------|------|---------|----------|
+| `notes:toolbar-actions` | notes | noteId, getContent, setContent | Dictation, AI tools, formatting |
+| `notes:note-footer` | notes | noteId, content | Related items, AI summary, metadata |
+| `chat:composer-tools` | chat | conversationId, insertText | Image gen, file attach, slash commands |
+| `chat:message-actions` | chat | messageId, content, attachments | Reactions, translate, bookmark |
+| `chat:image-actions` | chat | imageUrl, messageId, metadata | Regen, edit, upscale, style transfer |
+| `schedules:event-actions` | schedules | eventId, event | Add to calendar, share, convert to task |
+| `admin:package-actions` | admin | packageId, package | Custom admin tools per package |
+
+Each host surface adds `sw.slots.renderAll()` calls at the appropriate
+locations. Extensions contribute via `sw.slots.register()` in their JS.
+The manifest `contributes` field makes the relationship visible to admins.
+
+---
+
+## Future Considerations
+
+- **Slot schema validation.** Currently context contracts are documentation
+  only. A runtime assertion mode (dev only) could warn when a contributor
+  receives unexpected props. Deferred — convention is sufficient pre-1.0.
+
+- **Slot visibility controls.** An admin might want to disable a specific
+  contribution without disabling the entire contributing extension. A
+  per-contribution enable/disable toggle in the admin UI. Deferred —
+  extension enable/disable is the current granularity.
+
+- **Cross-surface slot contributions.** An extension contributing to
+  `notes:toolbar-actions` AND `chat:message-actions` with the same
+  underlying logic but different UI. The `contributes` field already
+  supports multiple entries. The extension's JS registers into both
+  slots with slot-appropriate components.
+
+- **Backend event subscriptions between extensions.** Currently extensions
+  react to kernel events via `hooks`. Extension-to-extension events
+  (e.g., "image-gen completed" → "chat refreshes") flow through the
+  existing event bus — the generating extension's api_route publishes
+  via `realtime.publish()`, the consuming surface listens via
+  `sw.realtime.subscribe()`. No new primitive needed.

+# DESIGN — Storage Primitives
+
+**Version:** v0.8.0
+**Status:** Draft
+**Author:** Jeff / Claude session 2026-04-02
+
+---
+
+## Problem
+
+Extensions cannot access blob storage or managed disk paths. The existing
+`ObjectStore` interface (PVC + S3 backends) is fully implemented but only
+exposed to the admin status endpoint — no Starlark bridge exists. The `db`
+module provides structured data storage via extension-scoped tables, but
+there is no equivalent for binary files, no managed filesystem for tools
+like `git`, and no mechanism for extensions to declare environment
+requirements (pgvector, workspace root, S3) that the kernel validates at
+install time.
+
+This blocks every future capability that depends on file handling:
+RAG/vector search, LLM bridge, code workspaces, file upload/sharing,
+media processing, and document indexing.
+
+---
+
+## Non-Goals
+
+- Replacing the `db` module. Extension-scoped tables (`ext_{pkg}_{table}`)
+  are the structured data primitive and remain unchanged.
+- Building a KV store. Extensions that need key-value semantics declare a
+  table with `key TEXT, value TEXT` columns — the infrastructure exists.
+- Multi-tenant file isolation beyond package scoping. Team/user-level
+  file ACLs are extension-layer concerns built on top of these primitives.
+- Streaming / chunked upload through Starlark. Large file ingestion goes
+  through HTTP routes; the `files` module handles storage after receipt.
+
+---
+
+## Architecture
+
+Three new primitives plus one extension to the existing `db` module.
+
+### Primitive 1: `files` Starlark Module
+
+Bridges the existing `ObjectStore` into the sandbox. Follows the same
+pattern as `db_module.go`: a `Build*Module` factory, permission-gated,
+package-scoped key namespacing.
+
+**Permissions:** `files.read`, `files.write`
+
+**Starlark API:**
+
+```python
+# Write a file. content is string (UTF-8) or bytes.
+# metadata is an optional dict stored alongside (JSON-serialized).
+files.put(name, content, content_type="application/octet-stream", metadata={})
+
+# Read a file. Returns dict: {"content": <bytes>, "content_type": "...", "size": N, "metadata": {...}}
+# Returns None if not found.
+result = files.get(name)
+
+# Read metadata only (no content transfer). Returns dict or None.
+meta = files.meta(name)
+
+# List files by prefix. Returns list of dicts: [{"name": "...", "size": N, "content_type": "..."}]
+entries = files.list(prefix="", limit=100)
+
+# Delete a file. Idempotent — no error if missing.
+files.delete(name)
+
+# Delete all files under a prefix. Use with caution.
+files.delete_prefix(prefix)
+
+# Check existence without reading.
+exists = files.exists(name)
+```
+
+**Key namespacing:**
+
+All keys are automatically prefixed with `ext/{packageID}/`. An extension
+calling `files.put("models/v1.bin", data)` writes to the ObjectStore key
+`ext/my-extension/models/v1.bin`. Extensions cannot escape their namespace.
+
+Name validation rejects `..`, absolute paths, and control characters —
+same sanitization rules as `physicalTable()` in `db_module.go`.
+
+**Implementation notes:**
+
+- New file: `sandbox/files_module.go`
+- `FilesModuleConfig` struct mirrors `DBModuleConfig`:
+  ```go
+  type FilesModuleConfig struct {
+      PackageID    string
+      CanWrite     bool
+      Store        storage.ObjectStore
+  }
+  ```
+- Metadata is stored as a companion JSON object at key
+  `ext/{packageID}/_meta/{name}`. This avoids schema changes — the
+  ObjectStore interface is unchanged. The `files` module manages the
+  companion transparently.
+- Size limit per `files.put()` call: 50MB (configurable via
+  `EXT_FILES_MAX_SIZE`). Enforced in the builtin before calling
+  `Store.Put()`.
+- `files.get()` returns content as `starlark.Bytes` for binary safety.
+  Starlark's `Bytes` type was added in go.starlark.net v0.0.0-20240725214946
+  and handles non-UTF-8 content correctly.
+- If `ObjectStore` is nil (storage not configured), the module is not
+  injected — same pattern as `db` module when `r.db == nil`.
+
+**Runner wiring:**
+
+```go
+// In buildModulesWithLibCtx, add cases:
+case models.ExtPermFilesRead:
+    if filesLevel < 1 { filesLevel = 1 }
+case models.ExtPermFilesWrite:
+    filesLevel = 2
+
+// After permission loop:
+if filesLevel > 0 && r.objectStore != nil {
+    modules["files"] = BuildFilesModule(ctx, FilesModuleConfig{
+        PackageID: packageID,
+        CanWrite:  filesLevel == 2,
+        Store:     r.objectStore,
+    })
+}
+```
+
+Runner gains `SetObjectStore(s storage.ObjectStore)` setter, called from
+`main.go` after `storage.Init()`.
+
+---
+
+### Primitive 2: `workspace` Starlark Module
+
+Managed disk directories for extensions that need a real filesystem —
+git repos, compilers, ffmpeg, pandoc, code analysis tools. These tools
+cannot operate through put/get blob semantics; they need paths.
+
+**Permission:** `workspace.manage`
+
+**Starlark API:**
+
+```python
+# Create a named workspace directory. Returns the absolute path.
+# Idempotent — returns existing path if already created.
+path = workspace.create(name)
+
+# Get the path for an existing workspace. Returns string or None.
+path = workspace.path(name)
+
+# List workspace names for this extension.
+names = workspace.list()
+
+# Delete a workspace and all its contents.
+workspace.delete(name)
+
+# Disk usage in bytes for a workspace.
+size = workspace.usage(name)
+```
+
+**Directory layout:**
+
+```
+{WORKSPACE_ROOT}/
+  {packageID}/
+    {name}/
+      ... (extension-managed contents)
+```
+
+`WORKSPACE_ROOT` defaults to `/data/workspaces` (configurable via
+`WORKSPACE_ROOT` env var). The kernel creates the package subdirectory
+on first `workspace.create()`. Extensions own everything below their
+directory — the kernel does not inspect contents.
+
+**Implementation notes:**
+
+- New file: `sandbox/workspace_module.go`
+- `WorkspaceModuleConfig`:
+  ```go
+  type WorkspaceModuleConfig struct {
+      PackageID     string
+      WorkspaceRoot string
+  }
+  ```
+- Name validation: same rules as table names (`^[a-z][a-z0-9_]{0,62}$`).
+  No path separators, no `..`, no spaces.
+- `workspace.create()` calls `os.MkdirAll` for the scoped path.
+- `workspace.delete()` calls `os.RemoveAll` — destructive by design.
+  Extensions must handle confirmation in their own UX.
+- `workspace.usage()` walks the directory tree and sums file sizes.
+  Bounded by a 10-second context timeout to prevent hangs on huge trees.
+- **Quota enforcement** (optional): `WORKSPACE_QUOTA_MB` env var. When
+  set, `workspace.create()` checks cumulative usage for the package
+  before creating. Returns error if quota exceeded. Default: unlimited.
+- If `WORKSPACE_ROOT` is empty or not writable, the module is not
+  injected. Extensions that declare `workspace.manage` without the
+  root configured will have their permission granted but the module
+  absent — same degradation pattern as `db` when no DB is available.
+
+**Runner wiring:**
+
+```go
+case models.ExtPermWorkspaceManage:
+    if r.workspaceRoot != "" {
+        modules["workspace"] = BuildWorkspaceModule(ctx, WorkspaceModuleConfig{
+            PackageID:     packageID,
+            WorkspaceRoot: r.workspaceRoot,
+        })
+    }
+```
+
+Runner gains `SetWorkspaceRoot(path string)` setter.
+
+**Security considerations:**
+
+- The returned path is an absolute filesystem path. Extensions can pass
+  this to `http` module calls (e.g., POST a file to an API) or use it
+  in `db` records as a reference. They cannot execute arbitrary binaries —
+  the Starlark sandbox has no `os.exec`. Execution requires a sidecar
+  tier package or an `api_route` handler that shells out server-side.
+- For sidecar-tier packages that _can_ execute binaries, the workspace
+  path is the designated scratch space. The kernel ensures the path is
+  within the scoped directory via `filepath.Clean` + prefix check.
+
+---
+
+### Primitive 3: Capability Negotiation
+
+Extensions declare environment requirements in their manifest. The kernel
+validates these at install time and reports failures with actionable
+messages. This is what makes progressive enhancement strategies (e.g.,
+three-tier vector search) work.
+
+**Manifest field:**
+
+```json
+{
+  "id": "vector-store",
+  "capabilities": {
+    "required": ["files.read", "files.write"],
+    "optional": ["pgvector"]
+  },
+  "permissions": ["db.write", "files.write"],
+  "db_tables": {
+    "embeddings": {
+      "columns": {
+        "source_id": "text",
+        "chunk_text": "text",
+        "embedding": "vector(384)"
+      },
+      "indexes": [["source_id"]]
+    }
+  }
+}
+```
+
+`capabilities.required` — install fails if any are missing. Admin gets
+a clear error: "Package 'vector-store' requires capability 'pgvector'
+which is not available. Run `CREATE EXTENSION vector;` in your PostgreSQL
+database to enable it."
+
+`capabilities.optional` — install succeeds regardless. The capability
+state is queryable at runtime so extensions can degrade gracefully.
+
+**Runtime query (Starlark):**
+
+Settings module is the natural home since it's always available:
+
+```python
+# Returns True/False for a capability name.
+has_pgvector = settings.has_capability("pgvector")
+```
+
+**Kernel capability registry:**
+
+A simple function in the `handlers` package that probes the environment:
+
+```go
+func DetectCapabilities(db *sql.DB, isPostgres bool, workspaceRoot string, objStore storage.ObjectStore) map[string]bool {
+    caps := make(map[string]bool)
+
+    // pgvector: check pg_extension
+    if isPostgres && db != nil {
+        var exists bool
+        row := db.QueryRow("SELECT EXISTS(SELECT 1 FROM pg_extension WHERE extname='vector')")
+        if row.Scan(&exists) == nil && exists {
+            caps["pgvector"] = true
+        }
+    }
+
+    // workspace: check root is writable
+    if workspaceRoot != "" && storage.IsPathWritable(workspaceRoot) {
+        caps["workspace"] = true
+    }
+
+    // object storage: check configured and healthy
+    if objStore != nil {
+        if err := objStore.Healthy(context.Background()); err == nil {
+            caps["object_storage"] = true
+        }
+    }
+
+    // s3: specific backend check
+    if objStore != nil && objStore.Backend() == "s3" {
+        caps["s3"] = true
+    }
+
+    // postgres: dialect check
+    if isPostgres {
+        caps["postgres"] = true
+    }
+
+    return caps
+}
+```
+
+Called once at startup, stored on the `Runner` (or a shared config
+struct). Re-probed on admin request for the capabilities endpoint.
+
+**Install-time validation:**
+
+In the package install handler (`handlers/extensions.go`), after
+`ParseDBTables` and before `SyncManifestPermissions`:
+
+```go
+if caps, ok := ParseCapabilities(manifestMap); ok {
+    missing := CheckRequiredCapabilities(caps.Required, detectedCaps)
+    if len(missing) > 0 {
+        // Roll back: delete the just-created package row
+        h.stores.Packages.Delete(c.Request.Context(), pkg.ID)
+        c.JSON(422, gin.H{
+            "error":   "missing required capabilities",
+            "missing": missing,
+            "help":    capabilityHelpText(missing),
+        })
+        return
+    }
+}
+```
+
+**Admin API:**
+
+```
+GET /api/v1/admin/capabilities
+→ {"pgvector": true, "workspace": true, "object_storage": true, "s3": false, "postgres": true}
+```
+
+Displayed in the Admin UI alongside storage status. Gives operators
+visibility into what their deployment supports.
+
+---
+
+### Extension to `db` Module: Vector Column Type
+
+The existing `mapColType()` in `ext_db_schema.go` gains a `vector` type
+with progressive enhancement across backends.
+
+**Manifest declaration:**
+
+```json
+"db_tables": {
+  "embeddings": {
+    "columns": {
+      "embedding": "vector(384)"
+    }
+  }
+}
+```
+
+**Column type mapping:**
+
+| Manifest type    | PG + pgvector           | PG without pgvector | SQLite       |
+|------------------|-------------------------|---------------------|--------------|
+| `vector(N)`      | `vector(N)`             | `JSONB`             | `TEXT`       |
+
+Implementation in `mapColType`:
+
+```go
+case "vector":
+    // vector or vector(384) — extract dimension if present
+    dim := extractVectorDim(typStr) // returns "384" or ""
+    if isPostgres && hasPgVector {
+        if dim != "" {
+            return fmt.Sprintf("vector(%s)", dim)
+        }
+        return "vector"
+    }
+    if isPostgres {
+        return "JSONB" // store as JSON array, brute-force search
+    }
+    return "TEXT" // SQLite: JSON array as text
+```
+
+`hasPgVector` is passed through a new field on a `SchemaConfig` struct
+(or detected inline — the capability registry result is available at
+table creation time).
+
+**New `db` module function — `db.query_similar()`:**
+
+```python
+# Find rows with embeddings closest to the query vector.
+# Returns list of row dicts with _distance appended.
+results = db.query_similar(
+    table="embeddings",
+    column="embedding",
+    vector=[0.1, 0.2, ...],  # query vector (list of floats)
+    limit=10,
+    filters={"source_id": "doc-123"}  # optional WHERE clause
+)
+```
+
+**Backend dispatch:**
+
+- **PG + pgvector:** Uses `ORDER BY embedding <=> $1 LIMIT $2` with
+  native vector distance operator.
+- **PG without pgvector / SQLite:** Loads candidate rows (respecting
+  `filters`), deserializes JSON arrays, computes cosine similarity in
+  Go, sorts, returns top-N. This is the "it works but slowly" fallback —
+  acceptable for small corpora (<10k rows), documented as such.
+
+Implementation: new function `dbQuerySimilar()` in `db_module.go`,
+gated on `db.read` permission (read-only operation). The function
+checks `cfg.HasPgVector` to choose the fast or slow path.
+
+`DBModuleConfig` gains:
+
+```go
+type DBModuleConfig struct {
+    PackageID   string
+    CanWrite    bool
+    DB          *sql.DB
+    IsPostgres  bool
+    HasPgVector bool  // NEW: enables native vector ops
+}
+```
+
+Wired from the capability registry at module build time.
+
+---
+
+## New Permission Constants
+
+```go
+// In models/models_extension_perm.go:
+const (
+    ExtPermFilesRead        = "files.read"
+    ExtPermFilesWrite       = "files.write"
+    ExtPermWorkspaceManage  = "workspace.manage"
+)
+```
+
+Added to `ValidExtensionPermissions` map.
+
+---
+
+## Schema Changes
+
+**Migration 015 — none required for kernel tables.**
+
+The `files` module uses the existing `ObjectStore` interface — no new
+kernel tables. Metadata companions are stored as ObjectStore objects.
+
+The `workspace` module uses the filesystem — no tables.
+
+Capabilities are detected at runtime — no tables.
+
+The `vector` column type is handled by extension DDL generation in
+`ext_db_schema.go` — no kernel migration.
+
+The new permission constants are code-only changes.

+    # that runs sklearn. The vector-store library provides
+    # the data access pattern; clustering logic lives elsewhere.
+    pass
+```
+
+---
+
+## Future Considerations
+
+- **Content-addressed deduplication.** If multiple extensions store the
+  same PDF, the ObjectStore holds duplicate bytes. A SHA256-keyed blob
+  layer with refcounting would deduplicate transparently. Deferred —
+  adds complexity without clear need pre-1.0.
+
+- **Extension-to-extension file sharing.** The current design isolates
+  file namespaces per extension. A `files.grant(name, target_pkg_id)`
+  primitive could enable controlled sharing. Deferred — composition
+  through API routes is sufficient initially.
+
+- **Streaming upload for large files.** Starlark `files.put()` buffers
+  in memory. For files >50MB, extensions should use HTTP `api_routes`
+  with Go handlers that stream directly to ObjectStore. The `files`
+  module is for extension-internal storage, not user-facing upload.
+
+- **Workspace snapshots.** `workspace.snapshot(name)` → creates a
+  tarball in the `files` store. Useful for backup/reproducibility.
+  Deferred — extensions can implement this themselves.
+
+- **Rate limiting / quota on `db.query_similar()` fallback.** The
+  brute-force path loads all candidate rows into Go memory. For large
+  tables this is dangerous. A row-count guard (e.g., refuse if >50k
+  candidates) with a clear error message pointing to pgvector is the
+  right safety valve.

+# Design: Vector Column Type (v0.8.3)
+
+## Problem
+
+Extensions building semantic search, RAG, or recommendation features need to
+store and query high-dimensional vectors (embeddings). Without kernel-level
+support, each extension would need to reinvent storage, serialization, and
+similarity search — duplicating effort and missing the pgvector optimization
+path.
+
+## Design
+
+### Three-tier progressive enhancement
+
+| Backend | Column DDL | Storage | Search |
+|---------|-----------|---------|--------|
+| Postgres + pgvector | `vector(N)` + HNSW index | Native vector type | `<=>` operator (index-backed) |
+| Postgres (no pgvector) | `JSONB` | JSON array | Go-side cosine distance |
+| SQLite | `TEXT` | JSON string | Go-side cosine distance |
+
+Extensions declare `"vector(N)"` in their manifest `db_tables` block.
+The kernel maps this to the appropriate SQL type at install time based on
+detected capabilities.
+
+### Manifest example
+
+```json
+{
+  "db_tables": {
+    "documents": {
+      "columns": {
+        "title": "text",
+        "embedding": "vector(384)"
+      }
+    }
+  },
+  "capabilities": {
+    "optional": ["pgvector"]
+  }
+}
+```
+
+### API surface
+
+```python
+# Insert (vector as list)
+db.insert("documents", {"title": "hello", "embedding": [0.1, 0.2, ...]})
+
+# Similarity search
+rows = db.query_similar(
+    "documents", "embedding",
+    vector=[0.1, 0.2, ...],
+    limit=10,
+    filters={"active": True},
+    metric="cosine"
+)
+# → [{..., "_distance": 0.023}, ...]
+```
+
+### Dispatch paths
+
+**pgvector path** — SQL-side computation with index:
+```sql
+SELECT *, (embedding <=> $1::vector) AS _distance
+FROM ext_pkg_documents
+WHERE ... ORDER BY embedding <=> $1::vector LIMIT $2
+```
+
+**Fallback path** — Go-side computation:
+1. `SELECT * FROM table WHERE filters LIMIT 1000`
+2. Parse each row's vector column from JSON
+3. Compute cosine distance in Go
+4. Sort by distance, return top N with `_distance` injected
+
+### Dimension validation
+
+- Manifest: 1 ≤ N ≤ 4096 (validated by `parseVectorDim`)
+- Insert-time: no dimension validation (store whatever list is given)
+- Query-time: dimension mismatches produce distance = 1.0 (treated as unrelated)
+
+### Performance characteristics
+
+| Path | 1K rows | 10K rows | 100K rows |
+|------|---------|----------|-----------|
+| pgvector (HNSW) | <1ms | <5ms | <10ms |
+| Fallback (Go) | <10ms | ~100ms | Not recommended |
+
+Fallback caps at 1000 rows fetched. Extensions needing large-scale similarity
+search should declare `capabilities.optional: ["pgvector"]` and degrade
+gracefully.
+
+## Limitations
+
+- Only cosine distance metric (v0.8.3). L2 / inner product can be added later.
+- No dimension validation at insert time.
+- Fallback path fetches at most 1000 rows — not suitable for large datasets.
+- HNSW index is only created for pgvector backends.

+# DESIGN — Workflow System Redesign (0.9.x)
+
+**Version:** v0.9.0
+**Status:** Draft
+**Author:** Jeff / Claude session 2026-04-03
+
+---
+
+## Problem
+
+The workflow system spans ~7,600 lines across 25+ files and was built
+incrementally from v0.3.x through v0.7.10. It works, but several
+concepts are redundant, primitives are buried, and the Starlark module
+is read-only. Before shipping reference extensions (v0.10.x) that
+build on workflows, the system needs cleanup and promotion of reusable
+primitives.
+
+## Audit Summary
+
+Full audit in `/config/Downloads/AUDIT-workflow-0.9.md`. Classification:
+
+### KEEP — Core primitives that survive
+
+| Component | File(s) | Lines | Rationale |
+|-----------|---------|-------|-----------|
+| Engine core | `workflow/engine.go` | ~400 | Stateless state machine — Start, Advance, Cancel, version-pinned execution |
+| Conditional routing | `workflow/routing.go` | ~500 | Pure functions, 8 operators, well-tested (497 lines of tests) |
+| Automated processing | `workflow/automated.go` | ~300 | Starlark hook execution, cycle guard (max 10) |
+| Scanner | `workflow/scanner.go` | ~200 | Background SLA + staleness checks, 5-minute interval |
+| Signoff system | engine.go + handlers | ~400 | Multi-party approve/reject with quorum, role-gated |
+| Assignment queue | handlers | ~300 | Claim/unclaim/complete/cancel lifecycle |
+| Version snapshots | store + models | ~200 | Immutable snapshots, version-pinned instances |
+| Typed form system | `models/workflow.go` | ~300 | 8 field types, fieldsets, conditional visibility |
+| Store interface | `store/workflow_iface.go` | 61 methods | Complete lifecycle coverage |
+
+### OBE — Superseded by new design
+
+| Concept | Superseded by |
+|---------|---------------|
+| Per-stage `audience` field | Multi-page packages with mixed access declarations |
+| `entry_mode` (public_link/team_only) | Package-level `scope: adoptable` + per-page access |
+| `stage_mode` proliferation (4 values) | Collapse to 3: form / delegated / automated |
+| `stage_type` (simple/dynamic/automated) | Redundant with `starlark_hook` presence check |
+| `AdoptTeamWorkflow` clone | Package adoption model |
+| `ExportWorkflowPackage` endpoint | Standard package export |
+
+### PROMOTE — Buried features to expose as kernel primitives
+
+1. **Roles → kernel primitive**: `team_user_roles` table, manifest `requires_roles`,
+   team admin UI, kernel middleware, Starlark SDK
+2. **Typed forms → SDK primitive**: Move from workflow models to `forms` package,
+   FE SDK `sw.forms.render()` / `sw.forms.validate()`
+3. **Conditional routing → SDK primitive**: Starlark `routing.evaluate(rules, data)`
+4. **Workflow Starlark module → full read/write**: `workflow.start()`, `.advance()`,
+   `.cancel()`, `.submit_signoff()`
+
+---
+
+## Technical Debt
+
+### Starlark Converter Duplication
+
+Three files contain nearly identical Go↔Starlark conversion functions:
+
+| File | Functions |
+|------|-----------|
+| `workflow/automated.go` | `goToStarlark`, `starlarkDictToMap`, `starlarkToGo` |
+| `handlers/workflow_hooks.go` | `starlarkDictToMap`, `starlarkToGo`, `jsonToStarlark` |
+| `sandbox/workflow_module.go` | `goValToStarlark` |
+
+**Fix:** Consolidate into `sandbox/convert.go`.
+
+### Snapshot Format Inconsistency
+
+Two formats exist (wrapped `{stages, workflow}` vs legacy flat array).
+Three copies of the parser across engine, instance handlers, and
+assignment handlers.
+
+**Fix:** Consolidate into one exported function. Standardize on wrapped format.
+
+---
+
+## Sequencing
+
+| Version | Feature | Dependencies |
+|---------|---------|-------------|
+| **v0.9.0** | Starlark converter consolidation + snapshot format cleanup | None |
+| **v0.9.1** | `team_user_roles` table + management API + admin UI | None |
+| **v0.9.2** | `scope: adoptable` manifest field + adoption flow with role auto-populate | v0.9.1 |
+| **v0.9.3** | Promote typed forms to SDK primitive (`sw.forms`) | None |
+| **v0.9.4** | Deprecate `stage_type`, collapse `stage_mode` to 3 values | None |
+| **v0.9.5** | Full read/write workflow Starlark module | v0.9.0 |
+| **v0.9.6** | Conditional routing as SDK primitive | v0.9.5 |
+| **v0.9.7** | Multi-surface manifest + kernel route resolution | None |
+| **v0.9.8** | Wire roles into surface access (`access: role:X`) + kernel middleware | v0.9.1, v0.9.7 |
+
+Each step is CI-green independently. The first four are the high-value items.
+
+---
+
+## Files Affected (by component)
+
+### Converter Consolidation (v0.9.0)
+- New: `sandbox/convert.go`
+- Modified: `workflow/automated.go`, `handlers/workflow_hooks.go`, `sandbox/workflow_module.go`
+
+### Team Roles (v0.9.1)
+- New: migration (PG + SQLite), `store/team_roles.go`, `handlers/team_roles.go`
+- Modified: manifest validation, adoption flow, team admin UI
+
+### Typed Forms (v0.9.3)
+- New: `forms/` package (extracted from `models/workflow.go`)
+- New: `sw.forms` SDK module
+- Modified: workflow engine to import from `forms/` instead of inline
+
+### Workflow Starlark Module (v0.9.5)
+- Modified: `sandbox/workflow_module.go` — add start/advance/cancel/signoff
+- Modified: `workflow/engine.go` — extract interface to break circular import
+
+---
+
+## Non-Goals
+
+- Rewriting the workflow engine. The state machine is correct and stays.
+- Adding a visual workflow builder. That's an extension concern, not kernel.
+- Multi-tenancy changes. Team scoping works as designed.

+Tables are automatically namespaced as `ext_{package_id}_{table_name}`.
+Every table gets an auto-generated `id` primary key and `created_at` timestamp.
+
+Column types: `text`, `int`, `vector(N)`.
+
+The `vector(N)` type stores N-dimensional float vectors for similarity
+search via `db.query_similar()`. Storage adapts to the backend:
+Postgres + pgvector uses native `vector(N)` with HNSW indexes,
+Postgres without pgvector uses `JSONB`, SQLite uses `TEXT`. N can be
+1–4096. See the [Starlark Reference](STARLARK-REFERENCE) for query API.

+## Capabilities
+
+Extensions can declare environment requirements via the `capabilities`
+manifest field. The kernel validates these at install time.
+
+```json
+{
+  "capabilities": {
+    "required": ["postgres"],
+    "optional": ["pgvector", "workspace"]

+- **required** — install is rejected (HTTP 422) if any capability is missing.
+- **optional** — install succeeds with a logged warning. Query at runtime

+
+Detected capabilities: `pgvector`, `workspace`, `object_storage`, `s3`,
+`postgres`. The admin can view detected capabilities at
+**Admin > System > Capabilities** or via `GET /admin/capabilities`.
+
+## User Permissions
+
+Extensions can register custom permissions that the admin assigns to
+user groups. This controls access to extension features beyond the
+sandbox permission model.
+
+```json
+{
+  "user_permissions": ["image-gen.use", "image-gen.admin"],
+  "gate_permission": "image-gen.use"

+- **user_permissions** — on install, these are merged into the kernel's
+  permission registry. On uninstall, they are removed. The admin assigns
+  them to groups in **Admin > Groups**.
+- **gate_permission** — if set, the kernel checks this permission before
+  calling `on_request`. Unauthorized users get a 403 without the
+  extension code executing.
+
+In Starlark, check permissions inline via `req["permissions"]` or call
+`permissions.check(user_id, "image-gen.use")`.
+
+## Extension Composability
+
+Extensions compose with each other through three mechanisms: manifest-declared
+**slots** (UI injection points), **contributions** (UI components injected into
+those slots), and cross-package **function calls** via `lib.require()`.
+
+### Slots — Host Surfaces Declare Injection Points
+
+A surface declares named slots in its manifest where other extensions can
+inject UI components:
+
+```json
+{
+  "id": "notes",
+  "type": "surface",
+  "slots": {
+    "toolbar-actions": {
+      "description": "Toolbar action buttons",
+      "context": {
+        "noteId": "string",
+        "getContent": "function — returns note body",
+        "setContent": "function — replaces note body"
+      }
+    }
+  }
+}
+```
+
+The surface renders slot contents using the SDK helper:
+
+```javascript
+html`<div class="toolbar">
+    ${sw.slots.renderAll('notes:toolbar-actions', {
+        noteId: note.id,
+        getContent: () => editor.getValue(),
+        setContent: (text) => editor.setValue(text),
+    })}
+</div>`
+```
+
+### Contributions — Extensions Inject UI
+
+An extension declares which slots it contributes to:
+
+```json
+{
+  "id": "note-dictate",
+  "type": "extension",
+  "contributes": {
+    "notes:toolbar-actions": {
+      "label": "Dictate",
+      "icon": "🎤",
+      "description": "Voice-to-text dictation"
+    }
+  }
+}
+```
+
+In its JavaScript, it registers the component:
+
+```javascript
+sw.slots.register('notes:toolbar-actions', {
+    id: 'note-dictate',
+    priority: 200,
+    component: ({ noteId, setContent, getContent }) => {
+        // ... component implementation
+        return html`<button class="sw-btn sw-btn--ghost">🎤</button>`;
+    }
+});
+```
+
+Contributions are soft-coupled — install order doesn't matter. The admin
+can view all slots and contributors at **Admin > Packages** or via
+`GET /api/v1/admin/slots`.
+
+### Cross-Package Function Calls
+
+Any package that declares `exports` in its manifest can be called by other
+packages via `lib.require()`. The caller declares the dependency:
+
+```json
+{
+  "id": "note-ai",
+  "depends": ["llm-bridge"],
+  "permissions": ["api.http"]
+}
+```
+
+In Starlark:
+
+```python
+llm = lib.require("llm-bridge")
+result = llm.complete([{"role": "user", "content": prompt}])
+```
+
+The called function runs with the *target* package's permissions, not the
+caller's. This is the same security model as library packages.
+
+### Slot Naming Convention
+
+Slot names follow `{host-package-id}:{slot-name}`. The colon separates the
+namespace from the slot. Standard slots for first-party packages:
+
+| Slot | Host | Use Case |
+|------|------|----------|
+| `notes:toolbar-actions` | notes | Dictation, AI tools, formatting |
+| `notes:note-footer` | notes | Related items, AI summary |
+| `chat:composer-tools` | chat | Image gen, file attach |
+| `chat:message-actions` | chat | Reactions, translate, bookmark |
+| `chat:image-actions` | chat | Regen, edit, upscale |

+## Composability: Slots and Contributions
+
+Packages compose with each other through named UI injection points (**slots**) and **contributions**.
+
+### Declaring Slots (Host Surfaces)
+
+Surfaces declare slots where other extensions can inject UI:
+
+```json
+{
+  "slots": {
+    "toolbar-actions": {
+      "description": "Toolbar action buttons",
+      "context": {
+        "noteId": "string — current note ID",
+        "getContent": "function — returns note body text"
+      }
+    }
+  }
+}
+```
+
+Slot names are namespaced at runtime as `{package-id}:{slot-name}` (e.g., `notes:toolbar-actions`). The `context` field documents what data the slot provides — it is not enforced at runtime.
+
+### Contributing to Slots
+
+Extensions declare which slots they inject into:
+
+```json
+{
+  "contributes": {
+    "notes:toolbar-actions": {
+      "label": "Dictate",
+      "icon": "🎤",
+      "description": "Voice-to-text dictation"
+    }
+  }
+}
+```
+
+Contributing extensions can be installed before or after their host surface — the coupling is soft. The admin can view all slots and their contributors at `GET /api/v1/admin/slots`.
+
+### Cross-Package Function Calls
+
+Any package that declares `exports` can be called via `lib.require()`, not just library-type packages. The caller must declare the target in its `depends` array:
+
+```json
+{
+  "depends": ["image-gen"],
+  "permissions": ["api.http"]
+}
+```
+
 ## 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.

 Requirements:
-- The library must be declared in your package manifest's `dependencies`.

-- The library must be type `library`, status `active`, tier `starlark`.
+- The target package must declare `exports` in its manifest.
+- The target package must be status `active`, tier `starlark`.
+- Any package type (`library`, `extension`, `full`) can be called as long
+  as it declares exports. This enables full packages to expose callable
+  functions alongside their UI and API routes.
 - Circular dependencies are detected and rejected.
 - Results are cached per execution (calling `require` twice returns the
   same object).

+Check whether a user has a specific permission.
+
+```python
+if permissions.check(user_id, "image-gen.use"):

+```
+
+Returns `True` if the user has the permission, `False` otherwise (including

+permissions — works for both kernel and extension-declared permissions.

-# Tasks
-
-**Status: Proof of Concept**
-
-Task management surface rebuilt as a Starlark extension. Ships with core
-for SDK validation purposes, not as a permanent commitment.
-
-## Purpose
-
-Validates all three trigger primitives (event bus, webhook, cron) and
-proves the full extension surface stack: Starlark API routes, ext_data
-tables, SDK UI components, and notifications.
-
-## Graduation Criteria
-
-To become a permanent core package, tasks must meet:
-
-1. **Feature completeness** — assignees, comments, attachments, subtasks
-2. **Test coverage** — API contract tests in the ICD test runner
-3. **Performance** — tested at 1000+ tasks with acceptable load times
-4. **Design review** — UI/UX matches platform design language
-5. **No kernel special-casing** — runs purely through extension APIs
