added patterns
audio element 'play'/'pause' event listeners send WS messages alongside UI updates — same pattern as wireKeyboard()
created modified
lightsync/frontend/app.js
Audio element event listeners are the correct hook for mouse play/pause — they fire for all triggers (button click, keyboard, programmatic), so WS messages are sent exactly once regardless of source
Idempotent WS messages: both wireAudio() and wireKeyboard() send play/pause — harmless because server handlers set a boolean flag

Phase 05 Plan 04: Mouse Play/Pause WebSocket Fix Summary

Audio element event listeners now forward play/pause state to server via WebSocket, enabling UDP cue scheduling for mouse-initiated playback

Performance

  • Duration: ~1 min
  • Started: 2026-04-07T10:36:50Z
  • Completed: 2026-04-07T10:37:27Z
  • Tasks: 1
  • Files modified: 1

Accomplishments

  • Added client.send({ type: 'play', position: audio.currentTime }) to the audio 'play' event listener in wireAudio()
  • Added client.send({ type: 'pause', position: audio.currentTime }) to the audio 'pause' event listener in wireAudio()
  • Server is_playing flag now becomes True when playback is started via the transport bar mouse button
  • UDP cue scheduler (LOOKAHEAD=60ms) now fires animation commands for mouse-initiated shows, not just keyboard Space shortcut

Files Created/Modified

  • lightsync/frontend/app.js — Added client.send() calls to 'play' and 'pause' event listeners in wireAudio() (lines 135-136)

Decisions Made

Audio element event listeners ('play'/'pause') are the correct hook rather than modifying the button click handler. These events fire for ALL triggers — button click, keyboard shortcuts, or programmatic audio.play()/audio.pause() calls — ensuring the WS message fires exactly once per state change. Both wireAudio() and wireKeyboard() sending the same WS messages is harmless: the server handlers are idempotent (they set is_playing to a boolean value).

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

  • Gap closure complete: mouse play/pause now correctly triggers server-side cue scheduling
  • All 11 truths from Phase 05 verification should now be satisfied (previously 9/11)
  • Phase 05 live-show-execution is fully complete

Phase: 05-live-show-execution Completed: 2026-04-07
