With native video on, coming back from background audio left a black screen: a play overlay pinned at 0:00, a seek bar at zero, and a play button that did nothing. Nothing crashed — the process stayed up and the frontend kept logging — the transition was simply dropped. The two render paths resume by different means, and exitBackgroundAudioHandoff only ever performed one of them. The webview <video> reloads off its stream URL: an $effect watches it, reinitialises HLS or sets element.src, and canplay drives the seek and play. ExoPlayer owns no element and nothing watches the URL on its behalf — native playback is only ever started by an explicit player_play_item plus adapter load, which the component issues once, from onMount. So reassigning the URL restarted precisely nothing, and since player_exit_background_audio had already stopped the handoff's audio player, the backend came back holding no item at all. That is why the play button was inert: there was nothing loaded to play. The return now re-issues that pair on the native path, in the same order as the initial load, carrying the position the audio reached. Subtitle configurations are reused from the ones resolved at mount — ExoPlayer sideloads them as MediaItem.SubtitleConfigurations and cannot accept one after prepare(). Which path to take is decided by planHandoffReturn, a pure helper in backgroundAudioHandoff.ts, so the branch is unit-testable without mounting the player. It also folds in shouldResumeOnForeground, so a pause taken on the lockscreen during the handoff still wins over the snapshot captured on the way out. Verified on device (HONOR ROD2-W09, Android 16): handoff to audio-only at 69:54, return restored native video playing at 70:18. Previously the same sequence left the player idle and black. The requirements count pin in extract-traces.test.ts moves with the new DR-196.

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
