The resume check reads the local user_data row and nothing else, but mirror_user_data -- the only path by which server UserData lands in that table -- mirrored is_favorite alone, and returned early whenever that field was absent, which is exactly the shape of an ordinary watched episode. playback_position_ticks was therefore write-only from this device's perspective: watch 40 minutes in a browser, open JellyTau, and it resumed from whatever this device last saw, or offered no resume at all. Same user-visible symptom as the Android bug fixed earlier on this branch, from an unrelated cause -- which is why resume read as broadly flaky rather than as one defect. The mirror now carries the position alongside the favourite flag under the same pending_sync = 0 conflict rule, so a local position still waiting to be pushed is never pulled backwards by a server that has not yet heard where we got to. COALESCE(excluded.x, user_data.x) keeps the stored value for a field the server omitted rather than nulling it, and a row with neither field is still skipped rather than fabricated as zeroes. Mirroring alone was not sufficient. get_item -- the call the player route makes -- returned the cached copy on a hit and never consulted the server, so for an already-cached item the mirror never ran. It now refreshes in the background on a cache hit via race_with_refresh, the reusable form of what get_items already did inline. That asymmetry is why browsing a season picked up other devices' state while opening the episode directly did not. The refreshed value lands for the next read; the cache-first race still answers immediately. The DR/total counts in extract-traces.test.ts are updated for DR-154 and DR-155 -- that edit is the test's intended signal that the CI gate's denominator is live rather than frozen. Verified red->green in the jellytau-builder image: both new tests failed before the fix. Full Rust suite passes (634), cargo fmt clean, clippy adds no new warnings; frontend suite (933) and svelte-check clean. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

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
