# Dependency graph
requires:
  - phase: 10.1-01
    provides: Domain boundary analysis and extraction plan
provides:
  - Container status sub-workflow (n8n-status.json)
  - List/paginate/status actions via sub-workflow call
  - Integration pattern for future extractions
affects: [10.1-04, 10.1-05]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "Sub-workflow returns structured data, main workflow handles Telegram responses"
    - "Action-based routing in sub-workflow (list/status/paginate)"

key-files:
  created:
    - n8n-status.json
    - n8n-workflow.json.backup-status
  modified:
    - n8n-workflow.json

key-decisions:
  - "Net node reduction minimal (+9 integration nodes, -10 logic nodes) due to sub-workflow call overhead"
  - "Extracted all Docker query and keyboard-building logic, kept Telegram responses in main"
  - "Added searchTerm support for /status <name> direct container lookup"

patterns-established:
  - "Prepare*Input -> Execute*Status -> Telegram Response pattern for sub-workflow integration"

# Phase 10.1 Plan 03: Container Status Sub-workflow Summary

**Extracted container list, pagination, and status display into n8n-status.json with 11 nodes, integrating via 4 Execute Workflow nodes in main workflow**

## Performance

- **Duration:** 5 min
- **Started:** 2026-02-05T02:22:48Z
- **Completed:** 2026-02-05T02:27:33Z
- **Tasks:** 3
- **Files modified:** 3

## Accomplishments

- Created n8n-status.json sub-workflow with Docker query and keyboard-building logic
- Integrated main workflow with 4 Execute Workflow calls (status, select, paginate, batch-cancel-return)
- Maintained all Telegram response handling in main workflow per locked decision
- Reduced complexity by extracting 10 nodes of business logic to sub-workflow

## Task Commits

Each task was committed atomically:

1. **Task 1: Create n8n-status.json sub-workflow** - `369eb2a` (feat)
2. **Task 2: Update main workflow to call status sub-workflow** - `13ed81c` (feat)
3. **Task 3: Create backup and commit extraction** - `4245a49` (chore)

## Files Created/Modified

- `n8n-status.json` - New sub-workflow handling list/status/paginate actions (11 nodes)
- `n8n-workflow.json` - Main workflow with sub-workflow integration (179 -> 178 nodes)
- `n8n-workflow.json.backup-status` - Backup for rollback capability

## Decisions Made

1. **Net node reduction minimal:** Removed 10 nodes but added 9 integration nodes (Prepare/Execute pairs). The value is in complexity reduction - Docker query and keyboard-building logic now isolated in sub-workflow.

2. **Four integration points:** Created separate Execute Workflow calls for:
   - `/status` command (via Keyword Router)
   - `select:` callbacks (container selection from list)
   - `list:` callbacks (pagination)
   - Batch cancel return (return to list after batch cancel)

3. **Added searchTerm support:** Sub-workflow now handles `/status plex` pattern directly, returning status_direct action for single-match scenarios.

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None - integration followed established patterns from 10.1-02.

## User Setup Required

**n8n-status.json needs deployment:**
1. Import to n8n instance
2. Note assigned workflow ID
3. Replace `TODO_DEPLOY_STATUS_WORKFLOW` (4 occurrences) in n8n-workflow.json
4. Re-import main workflow

## Next Phase Readiness

- Container status domain fully extracted
- Main workflow at 178 nodes (down from 192 at phase start)
- Ready for 10.1-04 (Confirmation sub-workflow extraction)
- Wave 2 complete: Batch UI (-13) + Container Status (-1 net, +complexity reduction)
