The previous fix rebuilt the quality chain when converting persisted
models back to videos, but many consumers discarded it again by
rendering bestThumbnail (usually a maxresdefault.jpg that 404s for
older videos) as a single URL with no fallback.
Extract the retry logic from VideoThumbnailView into FallbackLazyImage
and use it at every in-app site that can iterate: player thumbnails
(mini bar, expanded sheet loaders, autoplay previews, tvOS audio-mode
artwork - previously a silent black screen), video info card and tvOS
header, and the tvOS playlist cover.
Sites that fetch or send exactly one URL are rewritten to the
always-available hqdefault variant via Thumbnail.reliableURL (exposed
as Video.reliableThumbnailURL): Now Playing artwork, Top Shelf
snapshots, remote control state, the frozen transition thumbnail,
blurred info background, navigation covers, and playlist covers
derived from a video's first thumbnail in Invidious/Yattee Server
responses.
Also invert RecentPlaylist's upgrade helper, which rewrote covers *to*
maxresdefault, walk the quality chain when caching download thumbnails
for offline artwork instead of giving up after one 404, and expand the
remaining single-thumbnail Piped conversions into full chains.
CloudKit record names carry a source scope suffix so the same channel
or video ID can exist under different sources, but the apply path
matched local entities by bare ID: incoming records could merge into an
entity from a different scope, and a remote deletion of one scope
deleted every local entity with that ID and cascaded scoped deletions
for all other scopes back to CloudKit.
- Match local entities on the full mapper-derived record name when
merging incoming records, materializing records for upload, and
applying remote deletions.
- Remote deletions now remove only the matching entity and no longer
queue CloudKit deletions (no echo, no cross-scope cascade).
- Insert dedupe for CloudKit-applied records is scope-aware, so a
same-ID record from a different source inserts instead of being
silently dropped. Remotely added bookmarks also update the
fast-lookup cache immediately.
- When conflict resolution during a fetch keeps newer local data, the
merge result is queued for upload; previously the server (and other
devices) kept the stale version unless the entity was edited again.
Strict timestamp comparisons prevent re-upload ping-pong between
devices.
Rewrites /vi/ID/{default|mq|hq|sd}default.jpg to maxresdefault.jpg when
saving/updating a recent playlist, so the card shows a sharper image
than the low-res search-result thumbnail.
