## v0.100.0 — Unified transactional IVM execution

**Status: Released (2026-09-09).** Derived from [v0.100.0.md](v0.100.0.md).

### Execution contract

| ID | Title | Status |
|----|-------|--------|
| IVM-100-1 | Scope graph boundary and FULL policy in one refresh context | ✅ Complete |
| IVM-100-2 | Reuse downstream delta capture for manual FULL refreshes | ✅ Complete |
| IVM-100-3 | Enforce FULL policy at every manual strategy decision | ✅ Complete |
| IVM-100-4 | Add experimental Graph V1 opt-in and capability reporting | ✅ Complete |
| IVM-100-5 | Add graph parity, rollback, and context-cleanup coverage | ✅ Complete |

### Recommended implementation order

1. Add the scoped refresh context and policy checks.
2. Make manual FULL refreshes publish downstream deltas.
3. Enable Graph V1 only through explicit opt-in.
4. Add focused unit and integration coverage.
5. Update release metadata and qualification evidence.
