Strawcore — new channel_feed_rss(channel_url) and subscription_feed
(bulk fan-out 50x via tokio buffer_unordered). Fetches the YouTube
Atom RSS at /feeds/videos.xml?channel_id=UCxxx. Each call is
~50-150ms vs ~500ms for the InnerTube channel_info page-scrape.
Deps added to strawcore wrapper Cargo.toml: reqwest (rustls-tls),
quick-xml, futures. reqwest dedupes against strawcore-core's
existing reqwest dep.
App — SubscriptionFeedViewModel.fetchChannelInto swapped to
channel_feed_rss. Parallelism cranked 12 -> 50 since each fetch is
lightweight now. perChannelMax dropped 30 -> 15 (the RSS upstream
cap is 15). RSS doesn't carry duration / viewCount / avatar — those
backfill on tap-through via the existing streamInfo path. Avatar
opportunistic-refresh dropped from this path (lazy-load on
ChannelScreen open is enough).
Hide-shorts content filter — new util/ContentFilter.kt with
looksLikeShort() (URL /shorts/ match OR title contains
'#shorts'/'#short'). Settings toggle defaults off. Filter applies
at row-emit in SubsPane, SearchScreen, ChannelScreen. Paid +
age-restricted stubs in place for vc=57 when strawcore-core gets
the flags.
Expected refresh time on 50 subs: ~30s sequential -> ~1s parallel-50
RSS.
