Caught during the cargo-ndk cross-compile — strawcore-core was
emitting its own libstrawcore_core.so (~306 KB per ABI) into Straw's
jniLibs. That .so is never loaded by Android; the wrapper crate's
libstrawcore.so is the only entry point.
rlib only is what consumer crates need.
Straw's wrapper crate already owns the name 'strawcore' (and that name
is baked into the Android .so file + Kotlin's System.loadLibrary call).
Renaming this extractor crate to 'strawcore-core' resolves the cargo
package-name collision so both can live in the same workspace dep tree.
Repo name on Gitea stays Sulkta-Coop/strawcore.
Port NewPipeExtractor's JS pipeline: player.js fetch + cache, sig and
nsig function extraction, deobfuscation, sticky-error caching.
src/youtube/js/
* runtime.rs — rquickjs wrapper (mirrors utils/JavaScript.java)
compile_or_throw + run(snippet, name, parameter)
* lexer.rs — match_to_closing_brace via the `ress` JS scanner
(NPE's lexer is derived from the same crate
upstream)
* extractor.rs — iframe_api → embed page fallback for player.js
URL, regex-driven hash extraction, clean-and-fetch
* signature.rs — 6 sig fn name regexes (front-most-recent),
deobf-function-body via lexer w/ regex fallback,
helper-object + global-string-array extraction,
signatureTimestamp, snippet assembler
* nsig.rs — 8 nsig fn name regexes (incl. array-indirection),
body via lexer w/ regex fallback, fixupFunction
early-return strip
* player_manager.rs — orchestrator + sticky-error cache mirroring

PORT DEVIATIONS from NPE (each flagged in code):
* dropped the 6th sig fn name regex (used Java backref \2; Rust's
`regex` crate is backtracking-free, so we substitute a loose form
that NPE itself half-broke per audit Track B §2.1)
* dropped the Java atomic group `(?>...)` from helper-object regex —
Rust's NFA is already linear-time
* nsig fixup substitutes `(?:"undefined"|'undefined')` for the
\1 backref; harmless loosening
* sig and nsig assembled snippets prepend `var` — QuickJS rejects
bare-assignment to undeclared identifiers; NPE relied on Rhino's
non-strict mode
Tests:
* 43 lib unit tests (up from 7 in Phase 1)
* 7 Phase 2 offline integration tests against a hand-crafted
minified synthetic player.js — exercises the full sig pipeline
(build_deobfuscator → runtime::run) and nsig fixup_function
* 7 Phase 1 live smoke tests still green
57/57 total green.
