# Journal - dingkang (Part 1) > AI development session journal > Started: 2026-08-26 --- ## Session 1: Complete direct edit document and revision foundation **Date**: 2026-08-27 **Task**: Complete direct edit document and revision foundation **Branch**: `feat/direct-edit-documents` ### Summary Completed the v2 direct-edit document, immutable revision storage, and area-config snapshot foundation. ### Main Changes - Added validated native-road-edits/v2 documents, revisions, content-addressed OSM, and snapshot-only compilation. ### Git Commits | Hash | Message | |------|---------| | `93f09e3` | (see git log) | | `3500237` | (see git log) | | `c0c8a16` | (see git log) | | `ba8eaba` | (see git log) | ### Testing - [OK] npm run format:check; npm run test; npm run test:client; npm run test:client:unit; npm run build ### Status [OK] **Completed** ### Next Steps - Start the direct-edit solver and API child task. ## Session 2: Direct-edit handle manifest **Date**: 2026-08-27 **Task**: Continue `direct-edit-solver-api`, step 2 **Git Commit**: `ab63d23` ### Summary Added junction reserve calculation, six-kind handle manifest generation, and shared native feature ID builders. The solver remains pure and empty documents remain an identity transform for compiled geometry. ### Testing - [OK] npm test; npm run format:check; npm run test:client; npm run test:client:unit; npm run build ### Next Steps - Implement the six constraint kinds and invariant diagnostics (step 3). ## Session 3: Direct-edit constraint solving **Date**: 2026-08-27 **Task**: Continue `direct-edit-solver-api`, step 3 **Git Commit**: `0eb404d` ### Summary Activated all six constraint kinds, added transactional validation and blocking diagnostics, and wired road profiles and junction plans into geometry compilation. ### Testing - [OK] npm test; npm run format:check; npm run test:client; npm run test:client:unit; npm run build ### Next Steps - Implement exact/recheck/pending/conflicted/stale replay matching (step 4).
