Narrated progress report — piper-tts 🎧 Narrated tab#144
Merged
Conversation
Builds on the narration-script builder (#143). Adds the generator + playback: - scripts/narrate-report.mjs (npm run dashboard:narrate / make dashboard-narrate): gathers REAL data — newest unified runs across both repos, recently-shipped commits, live perf metrics, the feature-tour clips — feeds buildNarration, then renders each segment to audio with piper-tts (high-quality female voice, en_US-lessac-high) + ffmpeg, plus a combined track and a narration.json manifest. - server.mjs: GET /api/narration (manifest) + GET /narration/<file>.mp3 (path-safe, mp3-only, HTTP Range); factored streamFile() shared with media serving; mp3 MIME. - app.mjs + page.mjs: a "🎧 Narrated" tab — plays each segment's audio while the synced media (trend chart / live video clip / screenshot) shows above and the transcript below, auto-advancing; live run updates no longer disturb the player. Voices + audio live under the already-gitignored test-artifacts/. Verified: 39 unit tests; manifest 14 segments / ~2.5 min; mp3 served with Range; traversal + non-mp3 rejected (400); browser playback renders chart + video media, survives a server poll cycle, 0 console errors.
