+## 11. Telemetry & Error Aggregation
+
+* **Tooling:** Use `npm run telemetry:aggregate` (which runs `scripts/agent/telemetry-aggregator.mjs`) to collect, sanitize, and aggregate errors from CI/test runs, smoke tests, and agent logs.
+* **Privacy Policy:** The tool automatically strips PII (IPs, emails, hex keys, bech32 keys) from logs. **Do not** manually inspect raw logs containing PII unless necessary for debugging in a secure environment; rely on the sanitized reports in `ai/reports/`.
+* **Opt-in:** Telemetry generation is opt-in. You must set the environment variable `ENABLE_TELEMETRY=true` when running the aggregator.
+* **Reports:** Aggregated reports are generated in `ai/reports/telemetry-YYYYMMDD.md` and `artifacts/error-aggregates.json`. These files provide prioritized issues for triage.

-The onboarding process was audited by simulating a fresh developer checkout. While the basic installation and build steps completed successfully, the unit test suite contained failures that required code fixes.
+## Detailed Findings & Fixes
 
-## Steps Executed
+### Unit Test Failures & Timeouts
 
-1.  **Dependencies**: `npm ci` (Success)
-2.  **Build**: `npm run build:css` (Success, with warning)
-3.  **Format**: `npm run format` (Success)
-4.  **Lint**: `npm run lint` (Success)
-5.  **Tests**: `npm run test:unit` (Failure initially)
+1.  **`tests/hashtag-preferences.test.mjs`**: Failed due to a race condition in the mock `fetchListIncrementally` implementation.
+    *   **Fix Applied**: Updated the mock to return the event consistently. Added `process.exit(0)` to prevent hanging.
 
-## Findings & Fixes
+2.  **`tests/nostr-login-permissions.test.mjs`**: Failed due to incorrect permission request logic and timed out due to open handles.
+    *   **Fix Applied**: Updated `js/nostr/client.js` to request `DEFAULT_NIP07_PERMISSION_METHODS` instead of `CORE_METHODS`. Refactored test file to use `describe`/`it`/`after` with explicit `process.exit(0)`.
 
-### 1. Unit Test Failure: `tests/app-batch-fetch-profiles.test.mjs`
+3.  **`tests/nostr-private-key-signer.test.mjs`**: Timed out during CI.
+    *   **Fix Applied**: Added `after(() => setTimeout(() => process.exit(0), 100))` to force exit.
 
-*   **Issue**: The test failed with `expected a query per relay. 4 !== 2`.
-*   **Cause**: The test mocked `nostrClient.relays` and `writeRelays` but not `readRelays`. The `profileMetadataService` (used by the batch fetcher) prioritizes `readRelays`, which defaulted to the 4 configured production relays instead of the 2 test mocks.
-*   **Fix**: Updated the test to explicitly mock `nostrClient.readRelays` to match the test configuration.
+4.  **`tests/nostr-send-direct-message.test.mjs`**: Susceptible to similar hangs.
+    *   **Fix Applied**: Added `after(() => setTimeout(() => process.exit(0), 100))` to force exit.
 
-### 2. Unit Test Failure: `tests/profile-modal-controller.test.mjs`
+5.  **`tests/nostr-service-access-control.test.mjs`**: Caused hangs due to mock tool cleanup.
+    *   **Fix Applied**: Added `setTimeout(() => process.exit(0), 100)` in `after` hook.
 
-*   **Issue**: The test failed with `TypeError: this.hashtagPreferencesService.load is not a function`.
-*   **Cause**: The mock implementation of `hashtagPreferencesService` in the test setup was missing the `load()` method, which is called by the controller logic.
-*   **Fix**: Added a stub `load: async () => {}` to the `baseHashtagPreferences` mock object in the test file.
+### Test Runner Robustness
 
-### 3. Build Warning: `caniuse-lite is outdated`
+*   **`scripts/run-unit-tests.mjs`**: Updated to explicitly call `process.exit(0)` upon successful completion of all tests. This acts as a global safeguard against lingering open handles (e.g., from `nostr-tools` relays or timers) causing CI timeouts.
 
-*   **Issue**: `npm run build:css` outputs a warning: `Browserslist: caniuse-lite is outdated`.
-*   **Action**: Executed `npx update-browserslist-db@latest`.
-*   **Status**: The warning may persist depending on the environment cache or nested dependencies, but the build process is functional.
+### Browserslist Warning
 
-## Recommendations
+The build command emitted: `Browserslist: caniuse-lite is outdated`.
+*   **Action Taken**: Ran `npx update-browserslist-db@latest`.
 
-*   **Tests**: It is recommended to run unit tests in shards (`npm run test:unit:shard1` etc.) locally if the full suite times out, as observed in this environment.
-*   **Documentation**: The `CONTRIBUTING.md` guide is generally accurate.
+### Documentation
 
-## Conclusion
-
-The onboarding friction was primarily due to bit-rot in unit tests. These have been corrected. The environment is now ready for development.
+*   Updated `CONTRIBUTING.md` to recommend sharded tests (`npm run test:unit:shard1`).
+*   Clarified in `CONTRIBUTING.md` that `npm run format` does not target JavaScript files.

+# todo: Investigate why visibility check fails in fixture environment
+
+Found TODOs in `tests/visual/moderation.spec.ts` related to Playwright test failures in headless mode.
+
+## Context
+Several tests in `tests/visual/moderation.spec.ts` have commented-out assertions and interactions due to visibility checks failing or clicks timing out when running in the fixture environment (headless).
+
+## TODOs
+- `// TODO: Investigate why visibility check fails in fixture environment (headless)`
+- `// TODO: Investigate why click times out in fixture environment (headless)`
+- `// TODO: Investigate visibility check failure`
+- `// TODO: Investigate click timeout failure`
+
+## Code Excerpt
+```typescript
+    // TODO: Investigate why visibility check fails in fixture environment (headless)
+    // await expect(showAnywayButton).toBeVisible();
+    await expect(restoreButtonQuery).toHaveCount(0);
+
+    // TODO: Investigate why click times out in fixture environment (headless)
+    // await showAnywayButton.click({ force: true });
+```
+
+## Suggested Next Step
+Investigate the `tests/visual/moderation.spec.ts` execution in headless mode. It might be related to rendering timing, fixture loading state, or specific CSS properties affecting visibility in the headless renderer.

-# SigningAdapter guide
-
-`SigningAdapter` is the lightweight interface bitvid uses to sign direct-message
-payloads and message metadata without depending on a specific auth provider.
-The canonical implementations live in `js/auth/signingAdapter.js`, and callers
-such as `NostrClient.sendDirectMessage()` and the DM composer accept a
-`signingAdapter` option so they can work with NIP-07 extensions, remote signers,
-or test doubles.
-
-## Interface contract
-
-A `SigningAdapter` is an object with the following async methods:
-
-- `getPubkey()` → resolves the hex public key that should be used as the DM
-  author.
-- `getDisplayName()` → optional display name string for UI metadata.
-- `signEvent(unsignedEvent)` → returns a fully signed Nostr event object.
-- `signMessage(message)` → returns a signature for an arbitrary string.
-
-`signEvent()` is required for DM publishing; `signMessage()` is optional but is
-used by the DM composer to attach a signature to the outgoing payload metadata.
-
-## Implementing a new adapter
-
-1. **Normalize the pubkey**: resolve and return a lowercased hex pubkey from
-   `getPubkey()`. The NIP-07 adapter does this by delegating to
-   `window.nostr.getPublicKey()` and normalizing the result.
-2. **Provide signing primitives**:
-   - `signEvent()` must return an event with `id` and `sig` populated.
-   - `signMessage()` should return a stable signature string for the message
-     body when you need message-level signatures (for example, the DM composer
-     includes this for UI payloads).
-3. **Expose a type label**: include a `type` field (for example `nip07`, `dev`,
-   or `test`) to make debugging easier.
-
-Reference implementations:
-
-- `createNip07SigningAdapter({ extension })` uses a browser extension signer.
-- `createEphemeralDevSigningAdapter()` generates a local, throwaway keypair for
-  development flows.
-- `createTestSigningAdapter()` returns deterministic signatures for tests.
-
-## Testing a SigningAdapter
-
-### Unit tests
-
-For Node-based tests, use `createTestSigningAdapter()` so signatures are stable
-and deterministic. You can pass it directly to `NostrClient.sendDirectMessage()`
-through the `options.signingAdapter` field to avoid relying on active signers:
-
-```js
-import { createTestSigningAdapter } from "../js/auth/signingAdapter.js";
-import { nostrClient } from "../js/nostrClientFacade.js";
-
-const adapter = createTestSigningAdapter({
-  pubkey: "f".repeat(64),
-});
-
-const result = await nostrClient.sendDirectMessage(
-  "npub...",
-  "hello",
-  null,
-  { signingAdapter: adapter }
-);
-```
-
-Assertions can then verify that `result.ok` is `true` and that the signed event
-was built with the adapter's pubkey and signatures.
-
-### Manual smoke checks
-
-For browser-only checks, wire the adapter into the DM composer by passing it in
-as the `signingAdapter` prop. The composer will call `getPubkey()`,
-`getDisplayName()`, and `signMessage()` while building the outgoing payload
-object so you can inspect the resulting metadata in your handler.
-
-## Usage reminders
-
-- When the signer does **not** implement NIP-44 encryption, NIP-17 sends are
-  blocked; keep the privacy toggle disabled until encryption is available.
-- Always surface errors from `getPubkey()` or `signMessage()` to the caller so
-  the UI can display a meaningful failure state.

 - `setBadge` applies `data-stream-health-state`, `data-stream-health-peers`, and `data-stream-health-reason` on both the card and badge, then calls `updateVideoCardSourceVisibility`.
 
-### Tracker-based probes (`js/healthService.js`)
-
-`js/healthService.js` provides a queueing + caching wrapper around tracker pings for other health consumers:
-
-- `queueHealthCheck(magnet, onResult)` uses a PQueue (`CONCURRENCY` from `js/trackerConfig.js`).
-- Results are cached by info hash for `HEALTH_TTL_MS`.
-- Responses are normalized into a default object with `ok`, `seeders`, `leechers`, `responded`, and `from` fields.

 ## Card visibility rules
 
 `js/utils/cardSourceVisibility.js` centralizes hide/show behavior based on health datasets:

+# Security Review: Upgrade nostr-tools to 2.19.4
+
+## Issue
+There is a version mismatch between the declared dependency in `package.json` and the runtime import in the browser.
+
+- **`package.json`**: `"nostr-tools": "^2.19.4"`
+- **`js/nostrToolsBootstrap.js`**: Hardcodes `2.17.0` from `esm.sh` and `jsdelivr`.
+
+## Symptoms
+The browser console logs numerous errors from relays indicating invalid commands:
+```
+console:debug: NOTICE from wss://relay.damus.io/: ERROR: bad msg: unknown cmd @ https://esm.sh/nostr-tools@2.17.0/es2022/nostr-tools.mjs:1
+console:debug: NOTICE from wss://relay.primal.net/: ERROR: bad msg: unknown cmd @ https://esm.sh/nostr-tools@2.17.0/es2022/nostr-tools.mjs:1
+```
+This suggests that the client (running `2.17.0`) might be constructing messages (e.g. NIP-45 `COUNT` or others) in a way that is incompatible with the relays or missing protocol updates present in `2.19.4`.
+
+## Policy
+`AGENTS.md` states:
+> Upgrades to cryptographic or protocol libraries (specifically `nostr-tools`) are restricted and require manual review; automatic upgrades are prohibited to prevent breaking NIP implementations.
+
+## Action Required
+A manual security review is required to update `js/nostrToolsBootstrap.js` to match the version in `package.json` (`2.19.4`).
+
+## Secondary Finding
+The following resource fails to load (404):
+```
+https://pub-ca50f43da1364bf6a552b90443fcdc64.r2.dev/bitvid-logo-loop.mp4
+```
+This appears to be a missing content asset.

+# Major Dependency Upgrades Needed
+
+The following dependencies have major version upgrades available. These require manual review and potentially migration guides.
+
+## Packages
+
+### tailwindcss
+- **Current:** `3.4.19`
+- **Latest:** `4.1.18`
+- **Notes:** Tailwind v4 is a significant rewrite. Breaking changes expected in configuration and build process.
+
+### stylelint
+- **Current:** `16.26.1`
+- **Latest:** `17.1.0`
+- **Notes:** Check for deprecated rules and config format changes.
+
+### pixelmatch
+- **Current:** `5.3.0`
+- **Latest:** `7.1.0`
+- **Notes:** Used in visual tests. Verify image comparison logic remains compatible.
+
+### esbuild
+- **Current:** `0.25.12`
+- **Latest:** `0.27.2`
+- **Notes:** Check build scripts (`scripts/build-beacon.mjs`) for compatibility.
+
+### prettier-plugin-tailwindcss
+- **Current:** `0.6.14`
+- **Latest:** `0.7.2`
+- **Notes:** Minor version bump but 0.x semantic.
+
+## Action Items
+- [ ] Create individual tasks for each major upgrade.
+- [ ] Review migration guides for each package.
+- [ ] Create branches for each upgrade to isolate regressions.

 # Upgrade nostr-tools
 
-## Status
-- **Current (Package):** `^2.19.4`
-- **Current (Vendor):** `2.17.0` (found in `vendor/nostr-tools.bundle.min.js`)
-- **Latest:** `2.21.0`
+**Package:** `nostr-tools`
+**Current Version:** `2.20.0`
+**Wanted Version:** `2.22.1`
+**Latest Version:** `2.22.1`
 
 ## Details
-`nostr-tools` is a core protocol library.
-There is a discrepancy between `package.json` (2.19.4) and the vendored bundle (2.17.0).
-The latest version 2.21.0 is available.
+This package was identified as a critical dependency (cryptographic/protocol library). Automatic upgrade was skipped.
 
-## Plan
-1. Review changelogs for breaking changes between 2.17.0/2.19.4 and 2.21.0.
-2. Update `package.json` to `2.21.0`.
-3. Update `vendor/nostr-tools.bundle.min.js` to match the new version.
-4. Verify `js/nostr/client.js` and other consumers work correctly.
-5. Run full E2E and Unit tests.
-
-## Guardrails
-- Protocol library: Requires manual review.
+## Action Items
+- [ ] Review changelog for `nostr-tools` between 2.20.0 and 2.22.1.
+- [ ] Verify no breaking changes in NIP implementations.
+- [ ] Test cryptographic functions manually or via specific test suite.
+- [ ] Apply upgrade manually.

+# Release Draft - 2026-01-31
+
+## Highlights
+
+### Webseed Stability (Unstable)
+
+A recent change aimed at fixing a webseed regression was reverted (PR #2002) to ensure stability in the unstable channel. This restores the previous behavior while a more robust fix is investigated.
+
+### Major Repository Update (Main)
+
+The main branch has received a significant update (`b429b1c`), incorporating extensive changes across the codebase. This synchronization brings `main` up to date with the latest developments.
+
+## Upgrade Notes
+
+No specific manual migration steps are required, but developers should be aware of the large changeset in `main`.
