Review Checklist for Coherency & Ordering Integration focuses on stale-data escapes, coherency retry rate, fence latency. The goal is to map symptoms to boundary contracts, owner actions, and regression-proof closure.
Baseline manifest and revision are explicit.
Boundary contracts for this topic are current and approved.
Ownership map covers all open issues.
Focused and full regression evidence both exist.
Residual risks are either closed or bounded via waiver policy.
Owners signed: system architect, cache owner, verification lead.

No top-level issue should remain ownerless beyond one review cycle.Fabric correctness and contention behavior must be proven together.

Ask: what baseline, owner, and artifact prove this topic is truly closed?
State baseline manifest and owner with every closure metric.
Run cross-domain regression after every top-level fix.
Comparing results across different manifests.
Unowned issues slipping through review cycles.
Waiving risks without expiry and validation plan.
Coherency correctness requires consistent shareability, home-node behavior, and ordering barriers across CPU, DMA, and accelerator masters.
