Round-2 cruft audit punch list — mechanical deletes, no behavior change.
Whole modules deleted (no wrapper consumer):
* youtube/playlist_extractor.rs (297 LOC) — full playlist extraction
* youtube/linkhandler/playlist.rs (81 LOC) — playlist URL parser
* youtube/suggestion_extractor.rs (91 LOC) — search-as-you-type
* tests/stream_phase4_offline.rs (186 LOC) — tautological test
Dead pub fns + enum variants + constants:
* WEB_REMIX_* constants (3) + WEB_MUSIC_ANALYTICS_* constants (3)
* InnertubeClientRequestInfo::of_web_music_analytics_charts_client
factory + its charts_client_omits_platform_and_screen test
* SearchFilter::Music{Songs,Videos,Albums,Playlists,Artists} variants
(5 of 9 cases) + uses_music_endpoint helper + the search_extractor
'music search not implemented' reject branch
* Two #[allow(dead_code)] _suppress_unused stub fns and the imports
they were keeping alive (std::sync::Arc in js/extractor.rs,
NetworkError in stream_extractor.rs)
Renamed:
* search_extractor::test_helpers -> renderer_helpers. Mis-named:
it's production code called from channel.rs, not a test fixture.
potoken/ kept and documented as the designed Phase-5 extension point
for YouTube bot-detection — wrapper's Android side hasn't registered
a real provider yet, but the trait + global slot stay so when YT
forces po_token universally the integration is one Kotlin patch away,
not a Rust-side rewrite.
~580 LOC removed from production. Wrapper does not need to change.
