Kayos cd98673684 Phase 4 (partial) — stream value types + InnerTube /player helpers
Lands the data shapes + the HTTP layer for stream extraction. The
extractor orchestrator + DASH manifest creator are deferred to the
next session — the parsing logic is dense enough to want a focused
pass.

src/stream/
  * mod.rs       — StreamInfo + StreamInfoItem (full + 'card' shapes)
                   mirroring NPE StreamInfo.java + StreamInfoItem.java
  * delivery.rs  — DeliveryMethod (Progressive/Dash/Hls/Torrent)
  * audio.rs     — AudioStream (itag, format, url, bitrate, codec,
                   audio_track_id, content_length, etc.)
  * video.rs     — VideoStream (itag, format, url, resolution, fps,
                   bandwidth, codec, video_only flag)
  * subtitles.rs — SubtitlesStream (url, lang, auto_generated, mime)

src/youtube/stream_helper.rs
  * generate_content_playback_nonce() — 16-char LCG-shuffled cpn
  * get_web_metadata_player_response       (microformat + thumbnails only)
  * get_web_embedded_player_response       (embed-url + signatureTimestamp)
  * get_android_player_response            (full Android /player + poToken)
  * get_android_reel_player_response       (no-poToken fallback)
  * get_ios_player_response                (iOS — flagged with 917 KiB cap
                                            warning in the doc comment)

Per-helper headers + URL shapes match audit Track C §2.7 verbatim:
Android/iOS hit gapis endpoint with mobile UA; WEB family hits
www.youtube.com with the WEB headers.

Tests: 64 lib unit pass (up from 62 in Phase 3).

Next session: full stream_extractor.rs orchestrator + dash_manifest/
creator + Phase 4 done-when smoke (extract NCS Spektrem).

strawcore

Rust port of NewPipeExtractor (v0.26.2), YouTube-only. Plugs into Straw via UniFFI.

Why this exists

rustypipe regex-parses YouTube's player.js and reimplements the signature deobfuscator in Rust. Every YT player rotation breaks it. NPE embeds Mozilla Rhino and executes the JS function live — resilient by design, and that's the architecture we're mirroring.

The rustypipe-backed Straw build (vc=15..17) also routed playback through iOS-progressive URLs, which hit a server-side ~917 KiB end-byte cap. NPE uses the Android client + po_token → DASH manifest path, which doesn't see the cap. Same fix, different layer.

See memory/npe-audit-2026-05-24/SPEC.md in the workspace repo for the full plan.
