Review Checklist for UPF RTL Handoff focuses on handoff completeness, unresolved signal bindings, and policy mismatch defects. The goal is to link observed behavior to power-intent mechanism, ownership, and release risk.
Failing transition and states are explicitly documented.
Policy binding is proven in reports and waveform context.
Crossing inventory matches isolation/retention/shifter strategy.
UPF revision tags are aligned across flow stages.
Waiver status includes owner, expiry, and rollback criteria.
Owners signed: RTL lead, UPF owner, integration lead.

---------------- -----------------
intent policy RTL lead
implementation UPF owner
verification integration lead
Escapes happen when ownership is implicit.Cross-tool intent drift is a leading source of late low-power escapes.

Ask: what transition evidence proves this topic is closed, and which owner signs it?
State transition context must accompany every low-power metric claim.
Intent changes require simulation, formal, and implementation re-validation.
Comparing results from mismatched UPF revisions.
Assuming static checks replace transition validation.

Use this pack to rehearse low-power closure on low-power/upf-implementation-flow/upf-rtl-handoff/checklist: transition framing, policy ownership, implementation evidence, and release confidence.
State transition explicitly named with legal source/target states.
Crossing and domain ownership are mapped and agreed.
Policy controls are traced to always-on source logic.
Waveform bookmarks align controls with state timestamps.
Which policy object is first to deviate from intent?
Which owner can apply the smallest reversible fix?
What regression matrix proves no collateral damage?
Which waiver conditions would still block release?
