+# Phase 03 Plan 01: Basic Container Actions Summary
+
+**Single-match container actions (start/stop/restart) execute immediately via Docker API POST calls with graceful timeout**
+
+## Performance
+
+- **Duration:** 12 min
+- **Started:** 2026-01-30T10:00:00Z
+- **Completed:** 2026-01-30T10:12:00Z
+- **Tasks:** 3
+- **Files modified:** 1
+
+## Accomplishments
+- Action command routing for start/stop/restart patterns
+- Fuzzy container matching with case-insensitive substring search
+- Docker API POST calls for container lifecycle actions
+- HTTP status code handling (204 success, 304 already-in-state, error codes)
+- Error handling for Docker connection failures and action errors
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add action command routing to workflow** - `4848e7d` (feat)
+2. **Task 2: Implement container matching and action execution** - `f466a29` (feat)
+3. **Task 3: Handle action errors gracefully** - `2bd90c8` (feat)
+
+## Files Created/Modified
+- `n8n-workflow.json` - Extended with action branch: Parse Action, Docker List for Action, Match Container, Check Match Count, Build Action Command, Execute Action, Parse Action Result, Send Action Result, error handlers
+
+## Decisions Made
+- Treat HTTP 304 (container already in desired state) as success - user doesn't need to know it was already stopped/started
+- Use 10-second timeout (?t=10) for stop/restart to allow graceful shutdown
+- Route by matchCount with explicit error check (matchCount < 0) for Docker connection failures
+- Multiple match placeholder returns message indicating confirmation will come in next update
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Single-match actions fully functional
+- Ready for Plan 03-02: Confirmation flow for multiple matches
+- Inline keyboard buttons will use HTTP Request node (not native Telegram node) per RESEARCH.md
