# Phase 4: Cross-framework Linking (Plan 03) Summary
**JSON and Markdown exports now display entity relationships with resolved names and overview section**
## Performance
- **Duration:** 18 min
- **Started:** 2026-01-15T10:30:00Z
- **Completed:** 2026-01-15T10:48:00Z
- **Tasks:** 4
- **Files modified:** 2
## Accomplishments
- JSON export includes `linkedEntityDetails` array with resolved entity names
- Markdown export shows "Linked Entities" section for each entity with links
- Markdown export includes "Relationships Overview" section summarizing all links
- 4 new tests validate linked entity export functionality
## Task Commits
Each task was committed atomically:
1. **Task 1: Update JSON export to include resolved links** - `4b40d03` (feat)
2. **Task 2: Update Markdown export to show linked entities per entity** - `1c09de3` (feat)
3. **Task 3: Add relationships overview section to markdown** - `6079cf5` (feat)
4. **Task 4: Add export tests for linked entities** - `fe5edcc` (test)
## Files Created/Modified
- `src/storage/index.ts` - Added LinkedEntityDetails interface, resolved name lookup in JSON export, formatLinkedEntitiesAsMarkdown(), formatRelationshipsOverview(), collectAllRelationships() functions
- `src/tools/project.test.ts` - Added 4 tests for linked entity export functionality
## Decisions Made
- Used type intersection (`EntityType & {...}`) instead of interface extension because EntityType is a union type
- Resolved entity names during export for better human readability
- Created entityMap for O(1) name lookups to avoid N+1 queries during export
- Placed Relationships Overview section at end of markdown for easy scanning
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - Blocking] Fixed TypeScript error with interface extension**
- **Found during:** Task 1 (JSON export)
- **Issue:** TypeScript error TS2312 - interfaces cannot extend union types
- **Fix:** Changed `interface EntityWithLinkDetails extends EntityType` to `type EntityWithLinkDetails = EntityType & { linkedEntityDetails?: LinkedEntityDetails[] }`
- **Files modified:** src/storage/index.ts
- **Verification:** Build passes, tests pass
- **Committed in:** 4b40d03 (Task 1 commit)
---
**Total deviations:** 1 auto-fixed (1 blocking)
**Impact on plan:** TypeScript type system constraint required syntax change. No scope creep.
## Issues Encountered
None - plan executed as expected after type fix.
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- Phase 4 complete - all linking functionality implemented
- v1.1 UX Improvements milestone complete
- Ready for next milestone planning
