Mirror NPE's dependency-free spine in Rust:
* exceptions — NetworkError + ParsingError + ContentUnavailable
+ ExtractionError tree, with reqwest/serde_json conversions
* localization — Localization + ContentCountry, default (en, GB)
* downloader/ — Downloader trait, Request builder, Response,
reqwest blocking default impl
* page — continuation-token carrier
* image — Image + ImageSet + ResolutionLevel
(HEIGHT_UNKNOWN/WIDTH_UNKNOWN = -1)
* metainfo — title/content/url/url_text grab-bag
* service — StreamingService trait + LinkType + ServiceInfo
* newpipe — process-global Downloader / Localization /
ContentCountry singleton
Foundational invariants nailed down (per SPEC §3):
* HTTP non-2xx returns Ok(Response); only 429 throws NetworkError::Recaptcha
* Response header keys lowercase-normalized
* Request.add_header PARITY with NPE bug (silent overwrite);
append_header is our clean addition
* default Localization is en-GB
* No cookie jar in the default downloader
Tests: 7 unit + 7 live smoke against httpbin.org (gated on
'online-tests' feature). All green.

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.
