# Dependency graph
requires:
  - phase: 08-01
    provides: Container list keyboard and submenu infrastructure
provides:
  - Action button execution (start, restart, stop, update, logs)
  - Confirmation flow for dangerous actions (stop, update)
  - 30-second confirmation timeout
  - Cancel returns to container submenu
affects: [09-batch-operations]

# Tech tracking
tech-stack:
  added: []
  patterns: [confirmation-with-timestamp, action-routing-switch]

key-files:
  created: []
  modified: [n8n-workflow.json]

key-decisions:
  - "Timestamp in callback_data: Unix seconds embedded for 30-second timeout validation"
  - "Update shows progress: 'Updating...' message before long operation"
  - "All action results use editMessageText with updated keyboard based on new state"

patterns-established:
  - "Confirmation pattern: confirm:{action}:{name}:{timestamp} with 30s expiry check"
  - "Cancel pattern: cancel:{name} returns to container submenu"
  - "Immediate vs dangerous: start/restart/logs immediate; stop/update require confirmation"

# Phase 8 Plan 2: Action Execution and Confirmation Summary

**Action buttons wired to container operations with confirmation flow for dangerous actions**

## Performance

- **Duration:** 7 min
- **Started:** 2026-02-03T21:21:45Z
- **Completed:** 2026-02-03T21:28:48Z
- **Tasks:** 2
- **Files modified:** 1

## Accomplishments

- Routed action callbacks (action:start:name, action:stop:name, etc.) to container operations
- Start and Restart execute immediately with result feedback
- Logs retrieves 30 lines and displays in message
- Stop and Update show confirmation dialog with 30-second timeout
- Confirmed actions execute the operation and show result
- Cancel returns to container submenu with current state
- Expired confirmations show message and "Back to List" option

## Task Commits

Each task was committed atomically:

1. **Task 1: Route Action Callbacks to Container Operations** - `d158419` (feat)
2. **Task 2: Add Confirmation Flow for Dangerous Actions** - `ab7ce88` (feat)

## Files Created/Modified

- `n8n-workflow.json` - Added 37 new nodes for action execution and confirmation:

**Task 1 nodes (action routing):**
- Answer Action Callback (HTTP)
- Route Action Type (switch: start/restart/stop/update/logs)

- Get Container For Logs (HTTP)
- Build Logs Action Command (code)
- Execute Logs Action (exec)
- Format Logs Action Result (code)
- Send Logs Result (HTTP)
- Build Stop Confirmation (code)
- Send Stop Confirmation (HTTP)
- Build Update Confirmation (code)
- Send Update Confirmation (HTTP)

**Task 2 nodes (confirmation flow):**
- Answer Confirm Callback (HTTP)
- Check Confirm Expired (IF)
- Handle Confirm Expired (code)
- Send Expired Confirm (HTTP)
- Route Confirm Action (switch: stop/update)
- Prepare Confirmed Stop (code)
- Get Container For Stop (HTTP)
- Build Confirmed Stop Command (code)
- Execute Confirmed Stop (exec)
- Format Confirmed Stop Result (code)
- Send Confirmed Stop Result (HTTP)
- Prepare Confirmed Update (code)

- Check Pull Result (code)
- Inspect New Image (exec)
- Compare Update Images (code)
- Check If Needs Update (IF)
- Format No Update Needed (code)
- Send No Update Needed (HTTP)
- Stop For Update (exec)
- Verify Update Stop (code)
- Remove For Update (exec)
- Build Update Create Body (code)
- Build Update Create Command (code)
- Create For Update (exec)
- Parse Update Create Response (code)
- Start After Update (exec)
- Format Update Complete (code)
- Send Update Complete (HTTP)
- Answer Cancel Confirm Callback (HTTP)
- Prepare Cancel Return (code)
- Get Container For Cancel (HTTP)
- Build Cancel Return Submenu (code)
- Send Cancel Return Submenu (HTTP)

## Decisions Made

- **Timestamp format:** Unix seconds (not milliseconds) for compact callback_data
- **Timeout period:** 30 seconds as specified in context (not 2 minutes like legacy format)
- **Update progress:** Shows "Updating..." with hourglass while pulling image
- **Logs display:** 30 lines default, displayed in `<pre>` block with refresh button
- **Result feedback:** All actions update the message in-place with result and updated keyboard

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None - all nodes created and wired successfully.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- All action buttons now functional
- Confirmation flow complete for dangerous actions
- Ready for Phase 9: Batch Operations (select multiple containers)
- Update flow duplicates some logic from existing update command - could be refactored in future
