Vendor the pinned Rustix package with an Android-only weak libc lookup so missing statx returns ENOSYS and uses the existing stat64 fallback. Add an isolated Android smoke test with a hidden symbol and a seccomp filter that kills raw statx probes.
Verified 177 workspace tests, host Clippy, and ARM64 Android sandbox smoke test. ARM32 cross-target Clippy passes with the existing needless_return warning in binary.rs exempted; physical Android 10 ARM32 validation remains required.
Add category browsing, a two-column Recently Added grid, and a dedicated download queue. Keep compact navigation icons and their animations aligned with the active tab.
Keep profile avatars circular and report lyric enrichment outcomes accurately, preserving existing lyrics and supporting instrumental markers.
Decode borrowed input directly when it contains no CR/LF, retaining normalization for wrapped input. Verify trailing-bit compatibility, malformed-input errors, Unicode rejection and large payload parity.
Move normalized maps and track arrays into response envelopes instead of serializing them into another Value tree. Cover JSON parity, Unicode, track numbering and cancellation.
Keep full source artist credits in download responses and embedded tags, falling back to provider credits only when the source is empty. Add regression coverage for new and existing files.
Replace the Go backend with the Rust workspace and route Android/iOS through
UniFFI bindings. Include the migrated extension runtime, network, providers,
media metadata, downloads and library operations, with version 5.0.0+147.
Remove Go sources, adapters, native build selection and CI dependencies.
Build Rust unconditionally and lock the iOS Rust pod using a relative path.
Retain legacy source and migration evidence in a local ignored archive.
Validation: Android Kotlin compile and 53 native tests; Swift Rust-branch
equivalence and syntax; CocoaPods install; workflow, shell, Ruby, plist and
diff checks. Reuse the preceding 100 Rust tests, fmt/Clippy and five-ABI
build checkpoint; no new APK or iOS application build for this cleanup.
Known follow-up: URL/URLSearchParams globals are missing from the Rust JS
runtime. A controlled extension replay confirms a URL-resolution regression;
this commit does not fix that runtime gap.
