Brings the port up to current NewPipe Extractor coverage:
- visitorData: fetched + attached to the anonymous reel/web/ios/visionos
InnerTube contexts (upstream "always pass a valid visitorData"). Best-effort
— a failure returns None and extraction proceeds exactly as before. Cached
process-wide with a 15-min TTL, and invalidated when the primary android
response is rejected (decoy/playability) so a bad session self-heals.
- visionOS client (101): a 4th /player fetch, ON by default, recovering >360p
streams for SABR-only / made-for-kids videos where android/ios cap at 360p.
Formats merged android-first (android wins itag ties); a failure changes
nothing. HLS + DASH manifest branches now skip empty urls (an empty visionOS
url no longer shadows a real ios/android one).
- xtags: derive audio track type (original/dubbed/descriptive/secondary) from
the format xtags protobuf, falling back to the audioIsDefault heuristic when
absent. Hand-rolled protobuf walker, fuzzed (4M inputs, no panic); 32-bit
length guarded via try_from.
FFI surface unchanged (AudioStream gains an additive track_type the wrapper
may later surface). 155 lib + 7 integration tests, clippy -D clean.
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.
