When a user logs in, `profileCache` emits a `profileChanged` event. Previously, `HashtagPreferencesService` only reset its state on this event, failing to fetch the new user's preferences. This commit updates the subscription handler to call `load(pubkey)` when a new profile is set, ensuring interests and disinterests are reliably synchronized.
- fix `TypeError: Assignment to constant variable` in `HashtagPreferencesService.load` by changing `const` to `let` for `wasLoadedForUser`.
- Prevent existing cached preferences from being wiped when remote decryption fails.
- Migrated Kind 0 profile metadata storage to unified `profileCache.js` with partitioning and persistence.
- Added `defaultDTag` for hashtag preferences in `cachePolicies.js` to ensure consistent key resolution.
- Updated `hashtagPreferencesService.js` to use `profileCache` and implemented legacy data migration.
- Added `handleEvent` to `NostrClient` to centrally ingest Kind 0 events into the cache.
- Updated `authService.js` and `cache.js` to delegate profile operations to the unified cache system.
- Added `PROFILE_METADATA` schema to `nostrEventSchemas.js`.
- Add `isSessionActor` helper to `js/nostr/sessionActor.js` to identify ephemeral keys.
- Update `js/nostr/viewEvents.js` to namespace view deduplication caches by `actorPubkey` to prevent data leakage between sessions.
- Block comment publishing for session actors in `js/nostr/commentEvents.js`.
- Block watch history list publishing for session actors in `js/nostr/client.js`.
- Block user block list publishing for session actors in `js/userBlocks.js`.
- Block hashtag preference publishing for session actors in `js/services/hashtagPreferencesService.js`.
- Add inline documentation clarifying variable sources.
- Updated `profileCache.js` to support clearing runtime memory on signer change.
- Updated `NostrClient` to trigger `clearSignerRuntime` on `setActiveSigner`.
- Updated list services (`subscriptions`, `userBlocks`, `hashtagPreferences`, `watchHistory`) to listen for `runtimeCleared` and reload data.
- Updated `NostrClient` sync metadata methods to default to the active profile pubkey.
- Added `partition-updated` event emission to `profileCache`.
Implements a `SyncMetadataStore` to persist last-seen timestamps for replaceable lists (Kind 10000, 30000, 30002, 30015).
Adds `fetchListIncrementally` helper to `NostrClient` which performs per-relay `since` queries.
Updates `SubscriptionsManager`, `UserBlockListManager`, `HashtagPreferencesService`, and `adminListStore` to utilize incremental fetching.
Prevents local cache wipes when incremental fetches return empty results (indicating "no updates").
This commit updates `HashtagPreferencesService.load` to handle transient empty responses from relays more robustly.
- It prevents `reset()` if `wasLoadedForUser` is true and the fetch returns empty, ensuring existing data isn't wiped during connectivity issues or relay switches.
- It adds a staleness check to ignore incoming events that are older than the currently loaded data, protecting against out-of-sync relays returning obsolete preferences.
This addresses the issue where hashtag interests would disappear ("turn gray") or revert to older states shortly after login when video grid filters were applied.
Prevents `HashtagPreferencesService` from aggressively resetting local state to empty when a load attempt fails due to transient issues (like empty relay lists or network errors) if valid data is already loaded for the current user. This fixes a race condition where tags would briefly load correctly and then turn gray/disappear during application initialization.
- Fix circular dependency in `js/adminListStore.js` by importing from `js/nostrClientRegistry.js`.
- Update `js/services/hashtagPreferencesService.js` to include legacy kind 30005 in filters.
- Fix JSDOM mocking in `tests/modal-accessibility.test.mjs` (navigator getter) and `UploadModal` selectors.
- Add `getRoot()` to `js/ui/components/UploadModal.js` for API consistency.
- Update `tests/magnet-utils.test.mjs` expectations to reflect removed default tracker.
- Mock `ensureActiveSignerForPubkey` in `tests/moderation/submit-report.test.mjs`.
- Fix mock loader path in `tests/moderation/trust-seeds.test.mjs` to target `trustBootstrap.js`.
- Fix duplicate pointer tags in `js/nostrEventSchemas.js`'s `buildCommentEvent`.
- Update `tests/nostr/comment-events.test.mjs` and `tests/comment-event-builder.test.mjs` to match current code behavior (legacy kinds, unique tags).
