requires:
  - phase: 10.1-08
    provides: UAT diagnosis with root causes for 4 issues
provides:
  - Three UAT gap closures: disambiguation keyboard, confirmation cancel, /list command
  - Corrected data flow in Build Batch Keyboard (actionType field)
  - Dynamic input reference in Build Cancel Return Submenu
  - List command routing in Keyword Router

patterns-established:
  - "$input.item.json pattern: Use for nodes with multiple incoming paths instead of hardcoded node references"
  - "Action type distinction: Sub-workflow returns both 'action' (routing label) and 'actionType' (user's requested action)"

# Phase 10.1 Plan 09: UAT Gap Closure - Data Flow Fixes

**Fixed three data flow bugs: disambiguation keyboard action field, confirmation cancel predecessor reference, and missing /list command route**

## Performance

- **Duration:** 3 minutes
- **Started:** 2026-02-08T14:53:13Z
- **Completed:** 2026-02-08T14:56:53Z
- **Tasks:** 4
- **Files modified:** 1

## Accomplishments
- Fixed Build Batch Keyboard to read actionType field instead of action, enabling correct disambiguation keyboard text and callbacks
- Fixed Build Cancel Return Submenu to use dynamic $input reference, allowing confirmation dialog cancel to return to container status
- Added /list command to Keyword Router as alias for status command
- Deployed all fixes to production n8n instance

## Task Commits

Each task was committed atomically:

1. **Task 1: Fix Build Batch Keyboard to use actionType field** - `27326b8` (fix)
   - Changed `const action = $json.action` to `$json.actionType`
   - Fixes UAT issue: disambiguation keyboard showing "multiple all?" instead of actual action

2. **Task 2: Fix Build Cancel Return Submenu to use dynamic input** - `bbb9694` (fix)
   - Changed `$('Prepare Cancel Return').item.json` to `$input.item.json`
   - Fixes UAT issue: cancel from confirmation dialog not returning to container status view

3. **Task 3: Add /list command to Keyword Router** - `9e4bfb1` (feat)
   - Added "list" route with same outputKey as "status" route
   - Fixes UAT issue: /list command showing help text instead of container list

4. **Task 4: Deploy updated main workflow via n8n API** - `80555a7` (chore)
   - Deployed n8n-workflow.json to production instance (ID: HmiXBlJefBRPMS0m4iNYc)

## Files Created/Modified
- `n8n-workflow.json` - Main workflow with three bug fixes applied

## Decisions Made

**1. List command implementation: Alias approach**
- Added "list" as route in Keyword Router with same output as "status"
- Rationale: Status command already provides container list functionality; creating an alias is simpler than duplicating logic

**2. Dynamic predecessor reference pattern**
- Used `$input.item.json` instead of hardcoded node name
- Rationale: Build Cancel Return Submenu has two incoming paths; dynamic reference works for both

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

**API deployment field restrictions**
- **Issue:** Initial deployment attempts failed with 400 errors for read-only fields
- **Resolution:** Removed `active` and `tags` fields from deployment payload, keeping only `name`, `nodes`, `connections`, `settings`, `staticData`
- **Outcome:** Successful deployment with HTTP 200

## Next Phase Readiness

Three UAT gaps closed. Ready for UAT re-test to verify fixes:
1. Disambiguation keyboard should show "stop/start/restart" not "multiple"
2. Cancel from confirmation dialog should return to container status view
3. /list command should show paginated container list

No blockers for UAT re-test.
