Watch history was never loaded as part of the login cascade — it only loaded
when the For You feed refreshed or the history tab was opened. So on login (and
on other feeds) watched-video suppression and watch-history tags did nothing
until the user navigated there.
Kick off a non-blocking watchHistoryService.loadLatest() during the login
list-sync (deliberately NOT in parallelListTasks, so the feed never waits for
it). loadLatest schedules the background refresh, which emits "fingerprint" and
the For You feed re-runs (feedCoordinator) to apply suppression once resolved.
Deduped against the feed's own loadLatest via the in-flight refresh promise.

After a page reload the in-memory caches (service fingerprintCache and the
client watch-history cache) are empty, so loadLatest's non-blocking path returned
[] and the For You feed suppressed nothing until the slow background network
refresh (~150 encrypted chunk events over 2 sequential relay round-trips) landed.
Return the best available items immediately via getCachedSnapshotItems, which
falls back to the persisted localStorage snapshot. Reloads now suppress watched
videos right away using the last-known history, while the background refresh
still runs and corrects it (firing "fingerprint" to re-run the feed). Persisted
items were previously valid, so there is no correctness risk.

The For You feed awaited watchHistoryService.loadLatest() before rendering, and
loadLatest blocked on the full ~1500-item watch-history fetch on a cold load even
with allowStale:true (the `!allowStale || !hasCachedItems` guard awaited whenever
there was no cache). So the main feed froze behind the entire watch-history
resolution, and nothing re-ran the feed once history finished loading — watched
videos were never suppressed and watch-history tags never applied until a manual
refresh.
- watchHistoryService.loadLatest: allowStale callers now NEVER block. On a cold
load the refresh is kicked off in the background and the call returns
immediately with whatever is available (cached items, else the local queue).
- feedCoordinator.subscribeWatchHistoryFeedRefresh: subscribes to the
"fingerprint" event and, when the For You feed is active, debounced-re-runs it
so newly-resolved watched videos are suppressed and tags applied. Wired in at
bootstrap alongside feed registration.
The re-run reads the now-fresh cache (no further refresh scheduled), so there is
no loop. Adds feedCoordinatorWatchHistoryRefresh.test.mjs (debounced single
refresh while active; no refresh when inactive; idempotent subscription).

Profiling the live app showed the single biggest CPU cost was the relay pool
verifying every incoming event's schnorr signature synchronously on the main
thread: ~1.2s of secp256k1 work ([email protected] 855ms) during feed load and tab
switches, dropping to ~16ms when skipped. The pool was constructed as
`new SimplePool()` with no options, so nostr-tools used its default verifying
verifyEvent; the `verifyEvent: () => true` that looked like it disabled this
only existed on a mock tools object and was never wired to the real pool.
Move verification off the main thread instead of dropping it:
- Construct the pool with `verifyEvent: () => true` so it never blocks.
- Add signatureVerifyWorker (+ client) that verifies event batches in a Web
Worker and returns the valid ids; falls back to main-thread verification only
when Workers are unavailable (never silently trusts).
- VideoEventBuffer verifies each batch via the worker before committing, and
drops events that fail (fails closed). The verifier is injectable so tests can
virtualize the worker; subscribeVideos passes it through and returns the flush
promise from EOSE so commits are awaitable.
Tests: new signatureVerifyWorkerClient.test.mjs (worker protocol + drop-invalid
+ empty/no-id handling); videoEventBuffer.test.mjs and client.test.mjs adapted
to the async, verified commit path with a passthrough verifier.
Note: tests/nostr-delete-flow.test.mjs has a PRE-EXISTING failure on
`should not trigger subscription callbacks` (fails on clean unstable, and is a
standalone script not run by the unit-test runner); its edits here only adapt it
to the now-async flush.

fetchLatestListEvent fetched admin lists via fetchListIncrementally without an
explicit `since`, so it relied on the persisted per-relay lastSeen. Admin lists
are replaceable events with a single current version whose created_at does not
advance, so once lastSeen == that created_at, every later load queries
since=lastSeen+1 and the relay returns nothing — perpetually hiding the current
list and dropping admin lists whenever the local cache is absent.
Pass since: 0 to force a full fetch of the (tiny) current event each time. Other
list callers anchor an explicit since to their own cached state; admin lists
have no comparable per-list timestamp, so always re-fetching current is both
correct and cheap.
Adds tests/nostr/relayBatchFetcherReplaceable.test.mjs documenting the
replaceable-event since-gate at the fetcher boundary: relying on persisted
lastSeen hides the current event; since: 0 returns it.

subscribeVideos called pool.sub(getHealthyRelays(this.relays)) with no
empty-relay fallback, unlike the fetch paths in the same file. On a cold first
load the 5s relay connect probe can time out, marking every relay unreachable;
init() only warns and schedules a background reconnect (it does not throw), so
boot proceeds and the feed subscribes to ZERO relays. The background reconnect
later succeeds but nothing re-issues the subscription, so the feed stays empty
until the user refreshes (when the SWR cache renders) — the reported
"notes don't load on first visit / need a refresh" symptom.
Fall back to DEFAULT_RELAY_URLS when no relays are healthy, mirroring the
established pattern. Because the fallback bypasses the unreachable cooldown, the
subscription retries those relays directly and self-heals instead of staying
dead until refresh.
Adds tests/nostr/subscribeVideosRelayFallback.test.mjs: empty healthy set =>
default relays (never zero), populated healthy set => uses those relays.

Watch history is stored as up to ~150 separately NIP-44-encrypted chunk
events. Each chunk built a fresh cipher suite whose conversation-key cache
lived only in its own closure, so the ECDH conversation key (~12ms each in
the bundle) was re-derived once per chunk — multiplied across actor-candidate
and scheme-fallback retries this synchronously blocked the main thread for up
to ~20s after login/profile open (the reported freeze + fan spin-up).
Memoize the derived key by (scheme, privateKey, target) at module scope so it
is computed once per load and reused. Cleared on logout/identity change next
to clearDecryptionSchemeCache so a derived shared secret never outlives its
session. On the 150-chunk path this drops decrypt time ~1955ms -> ~182ms.
Adds tests/nostr/watchHistoryConversationKeyCache.test.js covering: 150 chunks
=> one derivation, distinct identities derive independently (no cross-identity
reuse), and cache-clear forces re-derivation.

Optimizes the `subscribeVideos` callback in `js/services/nostrService.js` to handle video updates incrementally, avoiding O(N*M) complexity during high-volume updates (e.g., initial load).
Changes:
- Modified `js/nostr/videoEventBuffer.js` to include deleted videos in the flushed batch, allowing consumers to handle deletions incrementally.
- Updated `js/services/nostrService.js` to process `updatedVideos` incrementally:
- Separates updates into active and deleted.
- Updates `this.videosMap` directly (removing deleted, adding/updating active).
- Filters and caches only the active updates (O(M)).
- Emits `videos:updated` with the full sorted list (derived from the updated map) to maintain API contract with consumers.
- Persists the full sorted list to localStorage.
This reduces the per-batch overhead significantly by avoiding O(N) filtering and map reconstruction for every batch of updates.

Replaced the local `extractDTagValue` function in `js/ui/components/DeleteModal.js` with the shared `getDTagValueFromTags` utility from `js/nostr/nip71.js` (exported via `js/nostr/index.js`).
Added a new unit test `tests/ui/components/DeleteModal.test.mjs` to verify the d-tag extraction logic and ensure the refactor is correct and safe. This test uses `jsdom` to mock the necessary DOM environment.
Co-authored-by: PR0M3TH3AN <[email protected]>
- Removed duplicated `extractDTagValue` method from `js/ui/components/RevertModal.js`
- Imported and used `getDTagValueFromTags` from `js/nostr/nip71.js`
- Added unit tests for `getDTagValueFromTags` in `tests/nostr/nip71-d-tag.test.mjs`
This reduces code duplication and ensures consistent d-tag extraction logic.

Replaced `pMap` with `Promise.all` in `publishRecords` to remove concurrency limit for faster syncing of multiple month records.
Measured ~50% improvement in mock benchmark (200ms -> 100ms for 10 items with concurrency 5 vs unbounded).
Note: The task description described the existing code as a sequential `for` loop, but the actual file used `pMap` with concurrency 5. This change optimizes it further by removing the concurrency limit as requested.

This commit replaces the duplicated d-tag extraction logic in `extractDTagValue` method of `js/app.js` with the standard utility function `getDTagValueFromTags` from `js/nostr/nip71.js`. This improves code reuse and maintainability.
The fallback logic for `extractDTagValue` now delegates to `getDTagValueFromTags` if `similarContentController` is not present, ensuring consistent behavior.
Verified with unit tests and linting.
