provides:
  - Rich session notification pipeline wired end-to-end (JSON file -> metadata -> HTML -> Telegram)

  - Git branch and timestamp extraction from JSONL transcripts

  - "Tail Brief sent as separate silent Telegram message (disableNotification: true) matching legacy TS pattern"
  - "Git branch extracted from raw JSONL (first 20 lines) since TranscriptEntry does not store gitBranch"

patterns-established:
  - "sendSilentMessage() for secondary content that should not trigger push notifications"
  - "extractGitBranch scans raw JSONL rather than parsed TranscriptEntry for metadata not in the entry model"

# Phase 11 Plan 02: Notification Wiring Summary

**Session notification pipeline wired end-to-end: rich HTML header via renderSessionNotification, silent Tail Brief as separate message, git branch and timestamps extracted from JSONL transcripts**

## Performance

- **Duration:** 2 min
- **Started:** 2026-03-26T23:43:18Z
- **Completed:** 2026-03-26T23:45:16Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments

- Expanded sendSessionNotification to accept sessionId, cwd, gitBranch, startTime, lastActivity and render via SessionNotificationData + renderSessionNotification()
- Added sendSilentMessage() method using disableNotification: true for Tail Brief delivery
- Added extractGitBranch(), extractFirstTimestamp(), extractLastTimestamp() helpers in main.swift
- Full pipeline: notification JSON -> metadata extraction -> rich HTML formatting -> Arc Summary message + silent Tail Brief message

## Task Commits

Each task was committed atomically:

1. **Task 1: Update TelegramBot.sendSessionNotification with rich formatting and silent Tail Brief** - `96df19a1` (feat)
2. **Task 2: Update main.swift notification handler to extract all JSON metadata fields** - `671813a2` (feat)

## Files Created/Modified

- `plugins/claude-tts-companion/Sources/claude-tts-companion/TelegramBot.swift` - Rich sendSessionNotification with SessionNotificationData, sendSilentMessage for Tail Brief
- `plugins/claude-tts-companion/Sources/claude-tts-companion/main.swift` - Notification handler passes all metadata; helpers for git branch and timestamp extraction

## Decisions Made

- Tail Brief sent as separate silent Telegram message (disableNotification: true) matching legacy TypeScript behavior
- Git branch extracted from raw JSONL file (first 20 lines) since TranscriptEntry does not store the gitBranch field

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## Known Stubs

None -- all functions are fully implemented with no placeholder data.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Full notification formatting pipeline is complete (Plan 01 formatting engine + Plan 02 wiring)
- Ready for next phase work on other subsystems
