A resumed transcode played nothing at all: every segment came back 400, hls.js exhausted its retries and gave up, while the same episode from the beginning was fine. Jellyfin builds each segment URI by echoing the master playlist's query string into it, and its segment handler opens by rejecting any request carrying StartTimeTicks > 0 (ArgumentException → 400). So one resume position on the playlist is copied onto every hls1/main/N.ts and 400s all of them — the `> 0` being exactly why starting from the beginning survived. HLS does not need the parameter: a playlist spans the whole item and asking for segment N *is* the seek. It is removed from the URL builder entirely rather than conditionalised — the builder cannot know whether its response will be segmented — and the position becomes a seek issued once the player has loaded. The progressive /Audio/universal builder behind the background-audio handoff has no segments and keeps its StartTimeTicks, which is why audio-only handoffs resumed correctly and video ones did not. Completing that across the boundary, since the URL no longer starts where the caller asked: - reloadSource(url, position) now means "reload and resume AT this absolute position": it seeks the element once the source is playable and clears the transcode offset to zero. It previously set the offset to the position and seeked nothing, which was correct only while the URL itself began there — left in place it would have shown 20:00 on the scrubber while the opening titles played, with no seek ever happening. - The transcoded resume path in the player page collapses into the same "seek after load" branch direct streams already used. - VideoPlayer's background-audio return does the same: no base, seek to the absolute position. - The stale test asserting StartTimeTicks is present is rewritten to keep its other half (an HLS master playlist, never a progressive stream.mp4, carrying the chosen source and audio track).

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
