The audio codec list sent to Jellyfin comes from MediaCodecList, which describes ExoPlayer — but video does not play through ExoPlayer. Android force-renders every video in the webview <video> element (the interim override in VideoPlayer.svelte) and Linux always has, and Chromium/WebKit decode a far narrower set than the platform does. A motorola edge 30 ships /vendor/etc/media_codecs_dolby_audio.xml, so it reported ac3,eac3; the server direct-played an E-AC-3 track with static=true and the webview built a video decoder and no audio decoder at all — full picture, no sound. The defect is triggered by capability rather than the lack of it, which is why a Fairphone and an Honor tablet play the same file on the same build: without the Dolby decoder they never claim the codec, so the server transcodes to AAC. Confirmed by A/B on the failing device — hevc+eac3 silent, hevc+aac audible, same session, same profile, same direct-play path, audio codec the only variable. video_audio_codecs narrows the platform list to the webview-decodable set for the video direct-play profile only. Audio-only playback really is the native player's, so that profile keeps the full list rather than transcoding music that plays perfectly well. A list with nothing decodable still claims aac, since a profile claiming nothing invites the server to give up instead of transcoding. The video codec list is deliberately untouched: HEVC direct-plays through the webview correctly, so the constraint is specific to audio. Test-first: the tests failed against the old behaviour before the filter existed, including the case built from the phone's real codec list. The requirement-count assertion in extract-traces.test.ts moves 280 -> 281 for the added DR, which is the deliberate edit that test exists to force. Not yet verified on device — the 0.4.7 APK was still building.

Traceability & Documentation
extract-traces.ts
Extract requirement IDs (TRACES) from source code and generate a traceability matrix mapping requirements to implementation locations.
bun run traces # Generate markdown report
bun run traces:json # Generate JSON report
bun run traces:markdown # Save to docs/traceability.md
bun run traces:coverage # Coverage gate — exits non-zero below 50%
The script scans all TypeScript, Svelte, and Rust files (plus scripts/)
looking for TRACES: comments and generates a comprehensive mapping of:
- Which code files implement which requirements
- Line numbers and code context
- Coverage summary by requirement type (UR, IR, DR, JA)
bun run traces:coverage is the supported way to check requirement coverage
locally — it runs the same computation CI does. Coverage denominators are
derived from docs/requirements.md at run time; they are never hardcoded. An ID
that appears in a TRACES: comment but is not defined in requirements.md is
reported as orphaned and does not count toward coverage (see DR-093).
Removed:
check-req-coverage.sh,check-test-coverage.sh, andfind-req-implementations.shwere deleted in July 2026. They read an undocumented@req:tag convention parallel toTRACES:, greppedsrc-tauri/unscoped (hanging on ~40 GB oftarget/artifacts), and in one case reported "all requirements implemented" from an empty result set.extract-traces.tsis the single source of truth for requirement coverage. See docs/specs/req-coverage-script-removal.md.
Example TRACES comment in code:
// TRACES: UR-005, UR-026 | DR-029
function handlePlayback() { ... }
See docs/traceability.md for the latest generated mapping.
CI/CD Validation
The traceability system is integrated with Gitea Actions CI/CD:
- Automatically validates TRACES on every push and pull request
- Enforces minimum 50% coverage threshold
- Warns if new code lacks TRACES comments
- Generates traceability reports automatically
For details, see:
- Traceability CI Guide - Full CI/CD documentation
- TRACES Quick Reference - Quick guide for adding TRACES
