# Phase 34: E2E Pipeline Verification - Context

**Gathered:** 2026-03-29
**Status:** Ready for planning
**Mode:** Auto-generated (verification-only gap closure phase)

<domain>
## Phase Boundary

Verify that the full session-end-to-Telegram pipeline (completed in Phase 31 outside GSD) satisfies E2E-01, E2E-02, E2E-03. Produce VERIFICATION.md with evidence. No new code — inspect codebase and verify existing implementation against requirements.

## Implementation Decisions

### Claude's Discretion

All implementation choices are at Claude's discretion — this is a verification-only phase. Inspect the existing codebase for evidence that:

- E2E-01: Full chain works: session ends → notification → summary → TTS via Python → karaoke subtitles → Telegram message
- E2E-02: TTS audio plays with native word-level karaoke (Python MToken onsets) during E2E flow
- E2E-03: tts_kokoro.sh CLI works end-to-end (regression check)

</decisions>

## Existing Code Insights

### Key Files to Inspect

- `plugins/claude-tts-companion/Sources/CompanionCore/NotificationWatcher.swift` — Session-end detection
- `plugins/claude-tts-companion/Sources/CompanionCore/TTSPipelineCoordinator.swift` — Pipeline orchestration
- `plugins/claude-tts-companion/Sources/CompanionCore/SubtitleSyncDriver.swift` — Karaoke sync with word onsets
- `plugins/claude-tts-companion/Sources/CompanionCore/TTSEngine.swift` — Python server delegation
- `plugins/claude-tts-companion/Sources/CompanionCore/TelegramBot.swift` — Notification delivery
- `~/.local/bin/tts_kokoro.sh` — CLI regression check

<specifics>
## Specific Ideas

No specific requirements — verification-only phase. Refer to REQUIREMENTS.md for E2E-01/02/03 acceptance criteria.

</specifics>

<deferred>
## Deferred Ideas

None — verification-only phase.
