+# Phase 03 Plan 03: Batch Confirmation Flow Summary
+
+**Inline batch confirmation with sequential execution for multiple container matches using callback_data array encoding and aggregated result reporting**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-01-30T13:45:19Z
+- **Completed:** 2026-01-30T13:48:07Z
+- **Tasks:** 3
+- **Files modified:** 1
+
+## Accomplishments
+- Replaced placeholder "Format Multiple Matches" with full batch confirmation flow
+- Build Batch Keyboard creates inline_keyboard with "Yes, stop N containers" and "Cancel" buttons
+- Batch callback_data encodes action code + array of container short IDs + timestamp
+- Parse Callback Data detects batch (c is array) vs single suggestion (c is string)
+- Route Callback now has 4 outputs: cancel, expired, batch, single (fallback)
+- Build Batch Commands prepares curl commands for each container
+- Prepare Batch Execution chains commands with RESULT_N: markers for parsing
+- Execute Batch Action runs all container actions in single shell command
+- Parse Batch Result extracts status codes and counts successes/failures
+- Format Batch Result builds human-friendly message with counts
+- Answer Batch Query removes button loading state
+- Delete Batch Confirm Message removes confirmation for clean chat
+- Send Batch Result displays final aggregated result
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Build batch confirmation message with inline keyboard** - `ab8d528` (feat)
+2. **Task 2: Handle batch confirmation callback** - `25a7994` (feat)
+3. **Task 3: Clean up UI after batch action** - `6737ef0` (feat)
+
+## Files Created/Modified
+- `n8n-workflow.json` - Extended from 41 to 49 nodes with batch confirmation flow:
+  - Build Batch Keyboard, Send Batch Confirmation (Task 1)
+  - Build Batch Commands, Prepare Batch Execution, Execute Batch Action, Parse Batch Result, Format Batch Result (Task 2)
+  - Answer Batch Query, Delete Batch Confirm Message, Send Batch Result (Task 3)
+
+## Decisions Made
+- Limit callback_data to 4 containers max (64-byte Telegram limit)
+- Use single shell command with && chained curls instead of n8n loops (simpler, no external modules needed)
+- RESULT_N:statusCode format for parsing multiple results from single execution
+- Reuse same UI cleanup pattern as single suggestion flow (answer -> delete -> send)
+
+## 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 container action flows complete: single match, no match (suggestion), multiple match (batch)
+- Callback handling supports both single and batch operations
+- Ready for Phase 04: Logs & Intelligence
+- Container update flow (pull + recreate) remains deferred
