Export, import, and split legacy history backups in Rust while preserving schema 15, all history columns, path keys, and atomic restore behavior. Keep provider refresh and pending history edits intact.
Move full and incremental ingestion, source snapshots, path keys, and download exclusion to native transactions. Preserve schema 17, FTS, WAL coordination, cancellation, and Android SAF timestamp backfill.
Move playlist parsing and serialization off the UI isolate, preserving field mapping, identifiers, durations, and export entries. Extend the shared parser contract tests with playlist fixtures.
Port LRC, enhanced LRC, and TTML parsing plus ID3v2.3 lyrics writing and picture encoding. Keep legacy contracts and deep XML fallback; guard asynchronous player updates against stale track results.
Move PCM beat analysis and spectrum cutoff estimation to cancellable Rust workers with the existing algorithms and isolated Dart fallbacks. Keep visual rendering and playback behavior unchanged.
Port the pinned Material quantizer and Dart RNG compatibility to Rust while keeping Material Score and final color schemes in Dart. Include exact palette fixtures, licenses, and Kotlin worker ABI coverage.
Introduce Android, iOS, and Dart worker dispatch with queued cancellation, binary inputs, and background JSON codecs. Move APK verification to streamed native SHA256 while retaining the isolated fallback.
Path and SAF scans wait at their next file checkpoint while paused and keep their position in memory. Cancel, backend shutdown and released request leases still end a paused scan.
Keep automatic Hi-Res replacement off by default. Require exact full-duration PCM equivalence across every channel before and after processing. Retain the original through publication and history persistence, restore it on failure or cancellation, and bound WAV format parsing.
Validated with 30 Rust tests, 46 Dart tests, clean analyzer/Clippy checks, Android ARM64 and iOS builds, and iOS simulator startup.
Introduce a per-file Hi-Res authenticity checker and optional auto re-download for flagged fake Hi-Res downloads. Adds Rust checker modules (fft, evidence, FLAC/WAV decoding, tests) and a mobile API (check_hires_authenticity). Wire platform bindings for Android/iOS and PlatformBridge. Add Dart HiResCheckService, UI HiResCheckCard, settings toggle (redownloadFakeHiRes) and integration in the download pipeline to quarantine and replace suspicious files with LOSSLESS when safe. Adds claxon FLAC dependency.
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.
