buildR2Key fell back to a static "uploads" namespace (and "video" slug) when
no torrent info-hash was available, so two distinct URL-first uploads sharing a
filename produced the SAME R2/S3 key — the second silently overwrote the first
object while the first video note still pointed at that URL (data loss).
WebTorrent uploads were already safe because the info-hash namespaces the key.
Add computeStorageContentHash(file) in js/r2.js: when no info-hash is present it
derives a deterministic content-based namespace — full SHA-256 of the bytes for
files ≤512 MB (idempotent: re-uploading the same file reuses the key), and a
SHA-256 fingerprint over name/size/mtime + sampled head/tail bytes above that,
so we never buffer a multi-GB video in memory. Wired into BOTH upload paths
(r2Service + s3UploadService) via a new storageIdentifier kept separate from the
info-hash, so magnet generation is unchanged.
Test: tests/storage-key-collision.test.mjs (distinct same-named uploads get
distinct keys; same content is idempotent; large-file fingerprint path samples
edges without buffering and stays deterministic). Full unit suite green.

A raw window.nostr probe in the user's browser (getPublicKey → nip04.encrypt
→ nip04.decrypt, bypassing ALL of bitvid) HUNG forever, with the extension's
own console showing `ObjectMultiplex - orphaned data for "background-liveness"`
+ `malformed chunk` + listener-leak warnings. That is the NIP-07 extension's
content-script ↔ background-service-worker channel being dead (classic MV3
worker death) — an extension/environment failure, not a bitvid bug. No client
change can force an unresponsive signer to answer; the fix is to reload/unlock
the extension.
What bitvid CAN do is stop failing silently. Add js/utils/signerHealthNotice.js:
after a few consecutive list-decrypt timeouts while the signer reports itself
present, emit ONE rate-limited, actionable user notice ("your signer isn't
responding to decryption — unlock/reload the extension and refresh") instead of
the silent 15-minute retry loop. Reset on any decrypt success so a transient
blip doesn't warn. Wired into blocks, hashtags, and subscriptions.
Also documents the definitive root-cause + all resilience increments in
KNOWN_BUGS #0. Test: tests/signer-health-notice.test.mjs (threshold, rate-limit,
success-reset). Full unit suite green.

Real-env console: signerStatus "present" but every block/hashtag decrypt
timed out at the 15s service budget, forever, retrying every ~15s for
15+ minutes — lists never loaded.
Reproduced deterministically with the channel-sim harness (latency
override): with per-call latency BELOW the service budget all lists load;
the instant it crosses the budget every list fails (NO) and retries
forever. A nip-07 decrypt is a postMessage round-trip to the extension's
single-threaded, possibly-sleeping service worker — under cold-login load
real extensions take 15-25s to answer even though the crypto is instant.
The earlier 6s per-call timeout was killing those in-progress decrypts.
Raise the budget across blocks/hashtags/subscriptions so a slow-but-
responsive signer completes instead of timing out:
- service-level DECRYPT_TIMEOUT_MS 15s → 30s
- per-call nip-07 decrypt timeout 6s → 25s interactive / ~10-12s background
- backoff cap 30s → 60s so a persistently dead signer settles into an
occasional heartbeat instead of pinning the extension every ~15s
Harness: at 16s/call (previously NO across the board) blocks +
subscriptions + hashtags now all decrypt (0 timeouts); healthy mode
unchanged (signer-ready ~1.2s). Full unit suite green. KNOWN_BUGS #0.

Built a deterministic NIP-07 channel-simulation harness
(scripts/perf/nip07-channel-sim.mjs) that reproduces the real cold-login
failure locally with a fake extension whose message channel drops under
concurrent load (MODE=overload), recovers (MODE=slow), or stays dead. It
seeds a real encrypted block list and reports whether it decrypts.
The harness pinned the actual root cause that the relay/breaker/timeout
work hadn't fixed: when the channel briefly drops during the login burst,
the per-scheme decrypt probe (Promise.any) rejects with
"message channel closed" — and every list service SWALLOWED that and
treated it as "the user has no blocks / no subs / no hashtags", or routed
it to a give-up branch. Either way: no retry, so the list stayed empty
until a full page refresh, even though the channel recovered seconds later.
Fix: classify transient failures (channel-death messages, breaker fast-fail
code, our own decrypt-timeout) and route them to the existing keep-stale +
scheduleDecryptRetry path instead of swallowing/abandoning:
- userBlocks: re-throw a transient sub-error out of the Promise.any probe
(was silently returning [] = "no blocks"); route it (and channel/breaker
errors) through the retry branch.
- hashtagPreferencesService + subscriptions: broaden the retry condition
from the timeout code only to any transient error, recursing into the
nested Promise.any AggregateError causes.
Harness verdict (MODE=overload, 16 channel drops): block list
BLOCK LIST DECRYPTED NO -> YES after the fix; signer-ready ~1.9s.
Adds getAppState().lists observability to the test harness. Full unit
suite green. KNOWN_BUGS #0.

Real-env console (2026-06-15) showed [signer-ready] taking ~48s and every
list decrypt timing out before AND after it. Root mechanism: a priority
inversion on the 2-slot NIP-07 request queue.
- List decrypts run at NIP07_PRIORITY.HIGH; the readiness gate's
permission/enable handshake ran at NORMAL. So a flood of HIGH-priority
decrypts jumped ahead of the gate and starved it — the channel never got
warmed, so the decrypts kept failing. Fix: add NIP07_PRIORITY.CRITICAL
(above HIGH) and run the permission/enable handshake at CRITICAL so it
always wins queue ordering.
- Login-time decrypt timeouts were 12-15s even though a healthy
nip04/nip44 decrypt is local crypto (~1s); the long window was only to
tolerate a first-grant prompt, which the gate already pre-grants. A 15s
timeout just monopolizes one of the two queue slots on a doomed call,
blocking the gate for 15s at a time. Cut blocks/hashtags/subscriptions
login decrypt timeouts to 6s so slots cycle ~2.5x faster (and the circuit
breaker trips in ~18s instead of ~45s). Service-level 15s wrappers stay
as a backstop (now strictly longer than the nip07 layer).
Part of KNOWN_BUGS #0 ("cut the burst, then add a safety net"). Full unit
suite green.

Real-env console shows the encrypted lists are FETCHED but DECRYPTION fails on
cold login: hashtags time out at 6s, blocks report signerStatus 'missing', DMs
throw 'helpers unavailable'. Root cause: a relay-connection storm to the user's
~20 dead NIP-65 relays (subsystems use uncapped relayManager read+write) starves
the nip-07 extension. Bumping the decrypt timeout to 15s (matching blocks) is a
partial mitigation for hashtags/subscriptions. The proper fix (bound reads to a
liveness-ranked healthy core incl. defaults + DM decrypt retry) is documented in
KNOWN_BUGS #0 — a first capReadRelays attempt was reverted because capping block
reads broke the security-critical user-blocks integration test.

performProfileFetch now issues ONE deduped, health-gated list() across all
relays via the L1 SubscriptionManager (the pool merges per-relay results),
replacing the manual per-relay fan-out. Newest-per-author selection unchanged;
legacy per-relay path retained as the manager-less fallback.
Spec correction: tests/app-batch-fetch-profiles.test.mjs asserted one query
PER relay (implementation detail); updated to assert one BATCHED query across
all relays. All behavioral assertions (cached hydration, newest profile
rendered, failing relay tolerated) unchanged; added a relays-targeting
assertion. Documented in TEST_INTEGRITY.md (SCN-profiles-batched).

The two feed-driving list subscriptions (kind-30000 follows, kind-30015/30005
hashtag prefs) now go through the L1 SubscriptionManager instead of the global
relaySubscriptionService singleton: centralized dedup + reconnect re-issue (the
lists self-heal after a relay drop). Handles are stored and closed on teardown;
relaySubscriptionService is retained as the manager-less fallback.
Verified: subscriptions-manager/-feed + hashtag-preferences suites pass (32);
flaky multi-relay harness still all-PASS; pool-access lint clean.

Replaces the per-video live report subscription (one pool.sub per visible
video × ~20 relays, re-fired on every reconnect — the ~1000 REQ/s storm) with
ONE batched SubscriptionManager subscription over the whole active id set,
updated in place as the set changes. Backfill fetches history only for
newly-added ids (one batched list()). Unchanged sets are a no-op (dedup guard).
MODERATION_REPORT_SUBS_ENABLED flipped back on. Trusted-mute subs were already
batched-by-author, so the relay cap + contact-loop fix already tamed them.
Legacy per-id path retained only for SubscriptionManager-less environments
(unit tests / mock clients). All 39 moderation tests pass; new cheat-resistant
batching test added; nip07-heat shows reports no longer storm (steady idle).

P1 foundation of the data-flow refactor (docs/architecture-refactor.md):
- js/nostr/subscriptionManager.js: the single chokepoint for relay reads.
Builds on relaySubscriptionService (dedup by key) and adds: health-gated
default relays, deduped one-shot list() with timeout, and a reconnect
registry that re-issues active subs centrally (instead of every subsystem
re-subscribing on reconnect — the storm amplifier). Callers pass batched
filters (one REQ for many ids), never per-item.
- Export RelaySubscriptionService class for test isolation.
- scripts/check-direct-pool-access.mjs + lint:pool-access: fail on NEW direct
pool.sub/list usage; 12 grandfathered files listed as migration targets
(allowlist may only shrink).
Nothing rewired yet — additive. Pilot (video feed) and per-subsystem
migration follow. Cheat-resistant tests included.

Real-environment console logs revealed nip-07 login pegging the CPU and
starving encrypted-list decryption via relay REQ storms (~1000 REQ/s):
- moderationService.rebuildTrustedContacts emitted "contacts"
unconditionally, forming an emit->fetch->emit loop (~1600 kind-3 REQ/s).
Now emits only on actual change. Regression test added.
- Per-video live report (kind 1984) and view-count (kind 30079)
subscriptions fan out O(videos x relays) and re-fire on every flaky-relay
reconnect. Circuit-broken behind flags until batched (see refactor plan).
- onVideosShouldRefresh now coalesces forced reloads (2s leading-edge
throttle) so list-change signals can't drive a reload loop.
- nip-07 queue reserves one foreground slot; DM decryption demoted to LOW
so background DM backfill can't starve feed-driving lists. Test added.

loadVideos awaited ensureAccessControlReady -> waitForReady -> _performRefresh
-> loadAdminState, which awaits a remote admin-list fetch. On a cold load that
waits for relays to connect (~5s) plus the fetch, stalling the feed ~10s before
any video renders. The cached admin state IS hydrated synchronously at
construction, but with markLoaded:false, so waitForReady blocked on a full
remote refresh even when a usable cache existed ("refresh fixes it").
ensureAccessControlReady now blocks only on a first-ever cold load WITH whitelist
mode (where showing non-whitelisted content before the whitelist arrives would be
wrong). In every other case — admin state hydrated from the localStorage cache,
already loaded, or blacklist-only mode — it kicks the refresh off in the
background (ensureReady) and renders immediately; the reactive
onWhitelist/onBlacklistChange handlers re-filter the grid once fresh lists land.
Adds accessControl.isHydrated() and a branching test
(nostr-service-access-control-ready.test.mjs).

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.

The NIP-07 adapter uses type "nip07" but all permission pre-granting
checks only matched type "extension", causing NIP-07 browser extension
users to fail decryption for block/mute lists, subscriptions, DMs, and
watch history. Hashtag preferences appeared to work because their read
path had a separate fix, masking the systemic issue.
Changes:
- shouldRequestExtensionPermissions() now matches both "extension" and
"nip07" signer types (central fix affecting DM signals, comments,
publish helpers, and watch history fetch)
- buildDmDecryptContext() pre-grants extension permissions for NIP-07
- userBlocks.js: remove capabilities-gated decryptor check that failed
with lazy NIP-07 module injection (same fix already in subscriptions.js);
always resolve signer regardless of allowPermissionPrompt; increase
fast-path relay timeout from 6s to 10s
- watchHistoryService: recognize NIP-07 type and always resolve signer
- All publish paths (blocks, subscriptions, hashtags, relays, uploads,
sharing, moderation) now pre-grant permissions for NIP-07 signers

- Remove redundant double signer readiness gate evaluation that added 5-10s
to the login path (authSessionCoordinator)
- Reduce decryption timeouts (10s→6s per scheme, 3s→1.5s retry delay,
8s→5s NIP-07 no-prompt, 45s→25s overall ensureLoaded) for faster scheme
fallback during list sync
- Fix storage tab unlock: remove overly strict capabilities check that
blocked lazy-injecting NIP-07 extensions, and add auto-unlock attempt
when profile modal opens with an active signer
- Fix subscription/hashtag decryption: always resolve signer for background
refreshes (was previously gated behind allowPermissionPrompt), and always
check window.nostr as fallback decryptor regardless of prompt mode
- Fix capabilities check in subscription decryption: use method existence
instead of dynamic capabilities getter that returns false during lazy
extension injection
- Wrap Promise.any decryptor calls in Promise.resolve().then() to catch
synchronous throws from NIP-07 adapter methods when extension modules
haven't loaded yet
- Make watch-history feed registration race-safe with pre-check and
try/catch for concurrent registration attempts
- Improve NIP-07 extension detection with DOMContentLoaded listener for
faster detection of extensions that inject during page load
