Verified first that event caching needs nothing: allEvents (incl. ingested NIP-71)
already persists to IndexedDB and every grid renders cache-first + merge-new. The
real gap was MEDIA: thumbnails/avatars/banners re-downloaded across visits.
Part 1 — Cache-Control on uploads (js/storage/s3-multipart.js):
computeCacheControl already stamped most media immutable but missed webp/avif/ico
and .torrent files (which fell to the 1h default). Added them — safe because
buildR2Key namespaces keys by infohash (content-addressed, a key's bytes never
change). Playlists (m3u8/mpd) stay short-lived (live manifests mutate in place).
Exported for tests.
Part 2 — service-worker image cache (sw.min.js):
Cross-origin images (the hosts bitvid does NOT control headers for) are now served
stale-while-revalidate from a versioned Cache-API cache (bitvid-images-v1):
- instant on revisit; background refresh self-heals changed images (and where
part 1's immutable headers apply, that refresh is served by the HTTP cache — free)
- opaque (no-cors) responses cached — exactly the external-thumbnail case
- LRU-capped (300); quota failures drop the cache and fail open; every handler
error falls back to plain fetch so a caching bug can never break images
- the activate handler's wipe-all now PRESERVES the current image cache (old
versions + other caches still wiped); same-origin assets untouched (they ride
the host HTTP cache + dist cache-purge pipeline)
- app._initServiceWorker registers the SW at boot when none exists, same
path/scope/options as webtorrent.js's setupServiceWorker so playback's later
register() resolves to the same registration (playback path untouched)
- SW_VERSION bumped
Tests: storage-cache-control (3, exported policy) + sw-image-cache (6 — evaluates
the REAL sw.min.js in a VM sandbox and drives its handlers: cold/warm/offline/
opaque flows, same-origin + non-image non-interception, activate preserves the
image cache). Lint + build green.

Adds the bucket-enumeration primitive the My Videos tab needs to find orphan and
missing files:
- s3 layer: ListObjectsV2Command wired into the SDK wrapper + a paginated
listObjects({ s3, bucket, prefix, maxKeys }) helper (follows continuation
tokens, bounded by maxKeys).
- r2Service.listVideoStorageObjects({ npub|pubkey }) — unlock-gated, lists under
the user's own u/<npub>/ prefix; returns { ok, reason, keys }. Body lives in
r2ServiceHelpers (with a shared buildProviderClient) so r2Service stays under
its file-size budget; ensureS3SdkLoaded is injectable via ctx for testing.
Tests + mutation-verified: never lists while locked (storage-locked, no call),
no-connection / missing-bucket gating, and unlocked listing is scoped to the
user's own u/<npub>/ prefix (empty-prefix mutation fails). Removing the lock gate
or widening the prefix each fail a scenario.
Build + full lint green (r2Service back under limit).

A 0-byte file produced a multipart upload with zero parts, which S3/R2 reject
with a cryptic CompleteMultipartUpload error. Guard file.size === 0 up front
with a clear message, before any S3 request is issued. Cloudflare-upload #4.
Test: tests/multipart-empty-file-guard.test.mjs.
