+# Phase 10 Plan 4: Agent History Schema v1.2 Summary
+
+**Extended agent-history.json schema to v1.2 with parallel execution tracking, dependency fields, and resume documentation**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-01-12T19:21:58Z
+- **Completed:** 2026-01-12T19:24:30Z
+- **Tasks:** 3
+- **Files modified:** 1
+
+## Accomplishments
+
+- Updated schema version from 1.0 to 1.2
+- Added 7 new fields for parallel execution tracking
+- Added queued and failed status values
+- Created parallel execution examples (plan-level, dependency)
+- Documented parallel resume workflow and conflict detection
+
+## Task Commits
+
+1. **Task 1: Update schema version and add new fields** - `eaed882` (feat)
+2. **Task 2: Add parallel execution examples** - `cc7e078` (feat)
+3. **Task 3: Document resume support for parallel groups** - `3743d1c` (feat)
+
+**Plan metadata:** (pending)
+
+## Files Created/Modified
+
+- `get-shit-done/templates/agent-history.md` - Extended with v1.2 schema, parallel fields, examples, resume docs
+
+## Decisions Made
+
+- Version bumped to 1.2 to indicate parallel execution capability
+- Parallel group format standardized as `phase-{phase}-batch-{timestamp}`
+- Resume documentation includes conflict detection for parallel scenarios
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## Phase 10 Complete
+
+All 4 plans executed:
+- 10-01: Renamed execute-phase → execute-plan workflow
+- 10-02: Created parallel execution workflow (execute-phase.md)
+- 10-03: Created /gsd:execute-phase command + parallelization config
+- 10-04: Extended agent-history schema to v1.2
+
+Parallel phase execution now available via `/gsd:execute-phase`.
+
+## Next Phase Readiness
+
+- Phase 10 complete
+- Milestone complete - all 10 phases finished
+- Ready for `/gsd:complete-milestone`
