# Phase 34 Plan 01: E2E Pipeline Verification Summary

**Static code-trace verification of full session-end-to-Telegram pipeline, native Python MToken karaoke onsets, and tts_kokoro.sh CLI script**

## Performance

- **Duration:** 2 min
- **Started:** 2026-03-29T08:00:11Z
- **Completed:** 2026-03-29T08:02:30Z
- **Tasks:** 1
- **Files modified:** 1

## Accomplishments

- Traced full E2E-01 chain through 7 source files: NotificationWatcher -> CompanionApp -> SummaryEngine -> TelegramBotNotifications -> TTSEngine -> SubtitleSyncDriver
- Confirmed E2E-02: native word onsets from Python /v1/audio/speech-with-timestamps flow directly into SubtitleSyncDriver without character-weighted approximation
- Verified E2E-03: tts_kokoro.sh exists as symlink at ~/.local/bin/, calls POST localhost:8780/tts/speak, accepts text via args/stdin/clipboard

## Task Commits

Each task was committed atomically:

1. **Task 1: Inspect codebase for E2E-01/02/03 evidence and produce VERIFICATION.md** - `ee20d549` (docs)

## Files Created/Modified

- `.planning/phases/34-e2e-pipeline-verification/34-VERIFICATION.md` - Pass/fail evidence for all three E2E requirements with file:line references

## Decisions Made

None - followed plan as specified. All three requirements verified as PASS.

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- All E2E requirements verified, gap from Phase 31 (outside GSD) is closed
- v4.9.0 milestone verification complete
