# Dependency graph
requires:
  - phase: 10-workflow-modularization
    provides: Initial sub-workflow extraction (Update, Actions, Logs)
provides:
  - Renamed sub-workflow files (n8n-update.json, n8n-actions.json, n8n-logs.json)
  - Domain boundary analysis for main workflow extraction
  - User-approved extraction plan for Waves 2-3
affects: [10.1-02, 10.1-03, 10.1-04, 10.1-05]

# Phase 10.1 Plan 01: Foundation and Domain Analysis Summary

**Renamed sub-workflows to n8n-{domain}.json pattern and established user-approved domain extraction boundaries targeting 115-125 nodes**

## Performance

- **Duration:** ~15 min
- **Started:** 2026-02-04
- **Completed:** 2026-02-05T02:08:59Z
- **Tasks:** 3
- **Files modified:** 4 (3 renamed, 1 created)

## Accomplishments

- Renamed 3 sub-workflow files to shorter, consistent pattern (n8n-update.json, n8n-actions.json, n8n-logs.json)
- Analyzed all 192 nodes in main workflow for domain extraction potential
- Identified 4 extractable domains: Batch UI (48 nodes), Container List (17 nodes), Confirmation (30 nodes), Matching (15 nodes)
- Established realistic target of 115-125 nodes (down from 192), accounting for 58 locked Telegram response nodes
- Received user approval on extraction boundaries

## Task Commits

Each task was committed atomically:

1. **Task 1: Rename sub-workflows** - `ff532aa` (refactor)
2. **Task 2: Analyze domain boundaries** - `fba90a6` (docs)
3. **Task 3: User approval checkpoint** - resolved via approval

**Plan metadata:** (this commit)

## Files Created/Modified

- `n8n-update.json` - Renamed from n8n-container-update.json
- `n8n-actions.json` - Renamed from n8n-container-actions.json
- `n8n-logs.json` - Renamed from n8n-container-logs.json
- `.planning/phases/10.1-aggressive-workflow-modularization/10.1-01-domain-analysis.md` - Complete domain analysis with extraction recommendations

## Decisions Made

1. **Realistic node target adjustment:** Changed target from 50-80 nodes to 115-125 nodes after discovering 58 Telegram response nodes are locked to main workflow per CONTEXT.md
2. **Wave prioritization:** Batch UI and Container List for Wave 2 (highest value), Confirmation and Matching for Wave 3
3. **Domains NOT extracted:** Telegram responses (locked decision), Update All (too small, merge with Batch), Action Routing (infrastructure)

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None - analysis completed as expected, user approved boundaries without modifications.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

Ready to proceed with Wave 2 execution:
- **Plan 10.1-02:** Extract Batch UI/Orchestration sub-workflow (target: 30-35 node reduction)
- **Plan 10.1-03:** Extract Container List/Menu sub-workflow (target: 12-15 node reduction)

No blockers. Domain boundaries are clearly defined with entry/exit points documented.
