R8 has broken release APKs here before by stripping the JNI-loaded player and security classes, and the only way to reproduce that was to build with the real signing key and clobber the install you actually use. `./scripts/build-and-deploy.sh release --device --debug` now builds a fully minified release APK — exactly what ships — into the .debug applicationId slot, signed with the local debug keystore: release com.dtourolle.jellytau 0.5.5 release --debug com.dtourolle.jellytau.debug 0.5.5-debug-release debug com.dtourolle.jellytau.debug 0.5.5-debug It shares the applicationId *and* the signature with the plain debug build, so the two replace each other cleanly rather than colliding, and the versionName suffix says which is currently installed. No real key is needed, so the side-by-side path deliberately skips write-keystore-properties.sh. The flag reaches Gradle as JT_SIDE_BY_SIDE=1. CI never sets it, and the release manifest merges byte-identical without it — verified both ways through processUniversalReleaseMainManifest. deploy-android.sh and build-and-deploy.sh learned the flag too, since the APK path is unchanged but the package to launch is not.

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
