+ - Are Web Components + Shadow DOM sufficient for security isolation? + - How do we handle shared state (e.g., global loading indicators, modals)? + - Can we use technologies like import maps with module federation for safer code loading? + +#### Phase 4: Trusted UI Plugins (Speculative) + +**Goal**: Separate the trust model for UI from backend Caplet logic. + +- **Two-tier system**: + + - **Caplets**: Headless services (untrusted, fully sandboxed) + - **UI Plugins**: Separate entities that call Caplet services (potentially more trusted) + +- **UI Plugin Trust Model**: + + - UI plugins go through different review/curation + - May have different permission model + - Could run in less-sandboxed contexts if they meet trust requirements + - Users explicitly install UI plugins separately from backend Caplets + +- **Benefits**: + + - Flexibility: Same backend Caplet can have multiple UIs + - Security: Can have stricter requirements for UI plugins + - Separation: Backend and frontend evolve independently + +- **Challenges**: + - More complex installation/discovery + - Coordination between Caplet and UI plugin developers + - User confusion about two types of plugins + +#### Open Research Questions + +1. **Secure UI composition**: Is it possible to achieve truly composable UI while maintaining strong security isolation? +2. **Web platform primitives**: Can we leverage Web Components, Shadow DOM, import maps, etc. effectively? +3. **User experience**: How do we maintain UX cohesion with third-party UI contributions? +4. **Performance**: What's the overhead of iframe/web component isolation?

Kernel Integration Layer + +- Kernel worker initialization and lifecycle management +- RPC client/server plumbing between extension contexts +- Stream-based IPC infrastructure +- Storage initialization and migration + +3. Caplet Management UI + +- Install/uninstall Caplets interface +- View all installed Caplets with versions +- Update management (review diffs, approve updates, pin versions) +- Search/browse Caplets from configured registries +- Direct installation by CID (for uncensored access) + +4. Capability Management System + +- Capability grant approval UI (shown on install and at runtime) +- Revocation controls for active capabilities +- Attenuation interface (time limits, rate limits, scoping) +- Capability audit log/visualization +- Inter-Caplet capability delegation review + +5. Security & Trust UI + +- Risk labels and warnings +- Attestation display (audits, security reviews, community ratings) +- Requested capabilities review on install +- Code diff viewer for updates +- Emergency quarantine controls (opt-in to DAO flags) +- Reproducible build verification status + +6.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements userspace E() infrastructure using @endo/captp to enable the background script to use E() naturally with kernel objects. Key changes: - Add CapTP setup on kernel side (kernel-browser-runtime): - kernel-facade.ts: Creates kernel facade exo with makeDefaultExo - kernel-captp.ts: Sets up CapTP endpoint with kernel facade as bootstrap - message-router.ts: Routes messages between kernel RPC and CapTP - Add CapTP setup on background side (omnium-gatherum): - background-captp.ts: Sets up CapTP endpoint to connect to kernel - types.ts: TypeScript types for the kernel facade - Update message streams to use JsonRpcMessage for bidirectional support - CapTP messages wrapped in JSON-RPC notifications: { method: 'captp', params: [msg] } - Make E globally available in background via defineGlobals() - Expose omnium.getKernel() for obtaining kernel remote presence Usage: const kernel = await omnium.getKernel();

charset=UTF-8 Content-Transfer-Encoding: 8bit Completes the migration from JSON-RPC to CapTP for background ↔ kernel communication and harmonizes the extension and omnium-gatherum packages. Remove the Kernel internal RPC infrastructure entirely: - Remove commandStream parameter from Kernel constructor and make() method - Remove #commandStream and #rpcService private fields - Remove #handleCommandMessage method and stream draining logic - Delete packages/ocap-kernel/src/rpc/kernel/ directory (contained only ping handler) - Update all Kernel.make() call sites across packages The Kernel no longer accepts or processes JSON-RPC commands directly. All external communication now flows through CapTP via the KernelFacade. Move background CapTP infrastructure from omnium-gatherum to kernel-browser-runtime: - Move background-captp.ts to packages/kernel-browser-runtime/src/ - Export from kernel-browser-runtime index: makeBackgroundCapTP, isCapTPNotification, getCapTPMessage, makeCapTPNotification, and related types - Delete packages/omnium-gatherum/src/captp/ directory - Delete packages/kernel-browser-runtime/src/kernel-worker/captp/message-router.ts (no longer needed since all communication uses CapTP) Both omnium-gatherum and extension now import CapTP utilities from kernel-browser-runtime. Update extension to use CapTP/E() instead of RpcClient: - Replace RpcClient with makeBackgroundCapTP in background.ts - Add getKernel() method to globalThis.kernel for E() usage - Update ping() to use E(kernel).ping() instead of rpcClient.call() - Remove @metamask/kernel-rpc-methods and @MetaMask/ocap-kernel dependencies Harmonize extension trusted prelude setup with omnium: - Delete extension separate dev-console.js and background-trusted-prelude.js - Add global.d.ts with TypeScript declarations for E and kernel globals - Both packages now use the same pattern: defineGlobals() call at module top Remove unused dependencies flagged by depcheck: - kernel-browser-runtime: Remove @endo/promise-kit - extension: Remove @MetaMask/ocap-kernel, @metamask/utils - kernel-test: Remove @metamask/streams, @metamask/utils - nodejs: Remove @metamask/utils - omnium-gatherum: Remove @endo/captp, @endo/marshal, @metamask/kernel-rpc-methods, @MetaMask/ocap-kernel, @metamask/utils Co-Authored-By: Claude Opus 4.5 --- packages/extension/package.json | 4 +- .../extension/scripts/build-constants.mjs | 2 +- packages/extension/src/background.ts | 120 ++++++---- .../src/env/background-trusted-prelude.js | 3 -

charset=UTF-8 Content-Transfer-Encoding: 8bit Consolidate CapletControllerState from multiple top-level keys (installed, manifests, subclusters, installedAt) into a single `caplets: Record` structure. Changes: - Add ControllerStorage abstraction using Immer for state management - Controllers work with typed state object instead of storage keys - Only modified top-level keys are persisted (via Immer patches) - Remove state corruption checks (no longer possible with atomic storage) - Fix makeFacet type - use string | symbol instead of keyof MethodGuard - Update PLAN.md to reflect new storage architecture 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- packages/omnium-gatherum/PLAN.md | 16 +- packages/omnium-gatherum/package.json | 1 + packages/omnium-gatherum/src/background.ts | 19 +- .../caplet/caplet-controller.test.ts | 543 +++++++++--------- .../controllers/caplet/caplet-controller.ts | 156 +---- .../src/controllers/caplet/index.ts | 1 + .../omnium-gatherum/src/controllers/facet.ts | 17 +- .../omnium-gatherum/src/controllers/index.ts | 9 +- .../storage/controller-storage.test.ts | 336 +++++++++++ .../controllers/storage/controller-storage.ts | 224 ++++++++ .../src/controllers/storage/index.ts | 5 + yarn.lock | 8 + 12 files changed, 932 insertions(+), 403 deletions(-) create mode 100644 packages/omnium-gatherum/src/controllers/storage/controller-storage.test.ts create mode 100644 packages/omnium-gatherum/src/controllers/storage/controller-storage.ts diff --git a/packages/omnium-gatherum/PLAN.md b/packages/omnium-gatherum/PLAN.md index caf22976e..fa746affc 100644 --- a/packages/omnium-gatherum/PLAN.md +++ b/packages/omnium-gatherum/PLAN.md @@ -106,7 +106,11 @@ capabilities. - `NamespacedStorage`: Scoped storage interface with automatic key prefixing - `controllers/storage/chrome-storage.ts`: `makeChromeStorageAdapter()` for Chrome Storage API - `controllers/storage/namespaced-storage.ts`: `makeNamespacedStorage()` factory - - Storage keys automatically prefixed: `${namespace}.${key}` (e.g., `caplet.com.example.test.manifest`) + - `controllers/storage/controller-storage.ts`: `makeControllerStorage()` for controller state management + - Controllers work with a typed `state` object instead of managing storage keys directly + - Uses Immer for immutable updates with change tracking + - Only persists modified top-level keys (via Immer patches) + - Storage keys automatically prefixed: `${namespace}.${key}` (e.g., `caplet.caplets`) - [x] **Caplet Manifest Schema** @@ -126,11 +130,11 @@ capabilities. - `list()`: Get all installed caplets - `get(capletId)`: Get specific caplet - `getByService(serviceName)`: Find caplet providing a service - - Storage keys (within `caplet` namespace): - - `installed`: Array of installed caplet IDs - - `${capletId}.manifest`: CapletManifest JSON - - `${capletId}.subclusterId`: Associated subcluster ID - - `${capletId}.installedAt`: Installation timestamp + - State structure (`CapletControllerState`): + - `caplets`: `Record` - all caplet data in a single record + - Uses `ControllerStorage` for state management + - Synchronous reads via `storage.state.caplets[id]` + - Async updates via `storage.update(draft => { ... })` - [x] **Dev Console Integration** diff --git a/packages/omnium-gatherum/package.json b/packages/omnium-gatherum/package.json index fdd737610..ee8f0e8b7 100644 --- a/packages/omnium-gatherum/package.json +++ b/packages/omnium-gatherum/package.json @@ -54,6 +54,7 @@ "@metamask/streams": "workspace:^", "@metamask/superstruct": "^3.2.1", "@metamask/utils": "^11.9.0", + "immer": "^10.1.1", "react": "^17.0.2", "react-dom": "^17.0.2", "semver": "^7.7.1", diff --git a/packages/omnium-gatherum/src/background.ts b/packages/omnium-gatherum/src/background.ts index 658214bb9..f1d60fbcb 100644 --- a/packages/omnium-gatherum/src/background.ts +++ b/packages/omnium-gatherum/src/background.ts @@ -17,10 +17,14 @@ import { ChromeRuntimeDuplexStream } from '@metamask/streams/browser';

Caplet manifest declares `requestedServices: ['serviceName']` +2. Omnium resolves each requested service by looking up providers in storage +3. Omnium retrieves the provider Caplet's root kref +4. Omnium passes the kref to the consumer via `parameters` object +5.

Install consumer-caplet (requests "echo" service) +// Omnium automatically resolves and passes echo service kref +await omnium.caplet.install(consumerManifest); +``` + +## Phase 2+ Service Discovery (Future) + +In Phase 2+, service discovery will be **dynamic** via a registry vat: + +- All Caplets receive a registry vat reference in `parameters.registry` +- Services can be requested at runtime: `await E(registry).getService('name')` +- Services can be revoked +- More flexible but requires registry vat infrastructure + +## Code Patterns + +### Using Logger + +```javascript +const logger = vatPowers.logger.subLogger({ tags: ['my-caplet', 'feature'] }); + +logger.log('Informational message', { data: 'value' }); +logger.error('Error occurred', error); +logger.warn('Warning message'); +logger.debug('Debug info'); +``` + +### Using Baggage (Persistent State) + +```javascript +import { makeScalarMapStore } from '@agoric/store'; + +export function buildRootObject(vatPowers, parameters, baggage) { + // Initialize persistent store + if (!baggage.has('state')) { + baggage.init('state', makeScalarMapStore('caplet-state')); + } + + const state = baggage.get('state'); + + return makeDefaultExo('root', { + setValue(key, value) { + state.init(key, value); + }, + getValue(key) { + return state.get(key); + }, + }); +} +``` + +### Using E() for Async Calls + +```javascript +import { E } from '@endo/eventual-send';

This creates presences from kernel krefs that forward method calls to kernel.queueMessage() via the existing CapTP connection. Key changes: - Add background-kref.ts with makeBackgroundKref() factory - Add node-endoify.js to kernel-shims for Node.js environments - Update kernel-facade to convert kref strings to standins - Fix launch-subcluster RPC result to use null for JSON compatibility - Integrate resolveKref/krefOf into omnium background The new approach uses @endo/marshal with smallcaps format (matching the kernel) rather than trying to hook into CapTP internal marshalling, which uses incompatible capdata format.

Options: - - - `getStatus()` returns caplet export krefs - - Registry vat pattern from PLAN.md Phase 2 - - Explicit `getCapletExports(subclusterId)` method - -2. **Bidirectional exports**: Should background be able to export objects to vats? - - Phase 1: No (background is consumer only) - - Future: Yes (requires reverse slot mapping) - -## Risks - -- **Performance**: Each E() call goes through kernel message queue -- **Memory leaks**: If FinalizationRegistry doesn't fire, krefs accumulate -- **Complexity**: Full object graph means any result can contain arbitrarily nested presences diff --git a/.depcheckrc.yml b/.depcheckrc.yml index ef2dad39f..c131a1352 100644 --- a/.depcheckrc.yml +++ b/.depcheckrc.yml @@ -50,6 +50,9 @@ ignores: # Used by @ocap/nodejs to build the sqlite3 bindings - 'node-gyp' + # Used by @metamask/kernel-shims/node-endoify for tests + - '@libp2p/webrtc' + # These are peer dependencies of various modules we actually do # depend on, which have been elevated to full dependencies (even # though we don't actually depend on them) in order to work around a diff --git a/package.json b/package.json index a283cb9c0..e0ab7b300 100644 --- a/package.json +++ b/package.json @@ -121,7 +121,8 @@ "vite>sass>@parcel/watcher": false, "vitest>@vitest/browser>webdriverio>@wdio/utils>edgedriver": false, "vitest>@vitest/browser>webdriverio>@wdio/utils>geckodriver": false, - "vitest>@vitest/mocker>msw": false + "vitest>@vitest/mocker>msw": false, + "@ocap/cli>@metamask/kernel-shims>@libp2p/webrtc>@ipshipyard/node-datachannel": false } }, "resolutions": { diff --git a/packages/extension/test/build/build-tests.ts b/packages/extension/test/build/build-tests.ts index fcd0aedd8..f293c5fe8 100644 --- a/packages/extension/test/build/build-tests.ts +++ b/packages/extension/test/build/build-tests.ts @@ -2,21 +2,13 @@ import { runTests } from '@ocap/repo-tools/build-utils/test'; import type { UntransformedFiles } from '@ocap/repo-tools/build-utils/test'; import path from 'node:path'; -import { - outDir, - sourceDir, - trustedPreludes, -} from '../../scripts/build-constants.mjs'; +import { outDir, trustedPreludes } from '../../scripts/build-constants.mjs'; const untransformedFiles = [ { sourcePath: path.resolve('../kernel-shims/dist/endoify.js'), buildPath: path.resolve(outDir, 'endoify.js'), }, - { - sourcePath: path.resolve(sourceDir, 'env/dev-console.js'), - buildPath: path.resolve(outDir, 'dev-console.js'), - }, ...Object.values(trustedPreludes).map((prelude) => { if ('path' in prelude) { return { diff --git a/packages/kernel-browser-runtime/package.json b/packages/kernel-browser-runtime/package.json index 7fb217db8..b05c3da53 100644 --- a/packages/kernel-browser-runtime/package.json +++ b/packages/kernel-browser-runtime/package.json @@ -84,6 +84,7 @@ "devDependencies": { "@arethetypeswrong/cli": "^0.17.4", "@endo/eventual-send": "^1.3.4", + "@libp2p/webrtc": "5.2.24", "@metamask/auto-changelog": "^5.3.0", "@metamask/eslint-config": "^15.0.0", "@metamask/eslint-config-nodejs": "^15.0.0", diff --git a/packages/kernel-browser-runtime/src/background-kref.ts b/packages/kernel-browser-runtime/src/background-kref.ts new file mode 100644 index 000000000..6d36e4c69 --- /dev/null +++ b/packages/kernel-browser-runtime/src/background-kref.ts @@ -0,0 +1,256 @@ +/** + * Background kref system for creating E()-usable presences from kernel krefs. + * + * This module provides "slot translation" - converting kernel krefs (ko*, kp*) + * into presences that can receive eventual sends via E().
