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.
Handle feature and featured separators across display, Android finalization and Rust tag writing. Split conjunction credits only when separate artist IDs confirm them, and offer a picker for multi-artist navigation.
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.
The direct-path walk re-validated every path component and stat'ed each file twice more. Children of an already validated directory now take one lstat of their own name, which still rejects symlinks and special files. Tag reads may use up to six workers on slow storage; artwork decoding stays serialized.
Tests cover walk order, size and modification time, and symlink rejection; they pass on the previous walk as well.
Native tag writers accept artist_tag_mode=primary and keep only the first credited artist in ARTIST and ALBUMARTIST for every format: FLAC download embedding, FLAC/Opus edits, and the ID3, MP4, APE and RIFF writers. The Android finalizer's FFmpeg fallback applies the same rule.
Rust and Kotlin share one separator set (comma, semicolon, ampersand, a spaced x, feat/ft/featuring/with) and test the same fixtures. The Go-parity split_vorbis pattern is unchanged. Refs #618.
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.
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.
Preserve romanization and translation metadata through Rust exports and cache, match rounded line times, and retain word endings. Highlight romanization with the main lyric clock in Material and Mornye.
Clear selection overlay ownership safely when collection screens are disposed. Add parser, rendering, cache and overlay lifecycle regression coverage.
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.
