UPF Formal Checks: Reports & Metrics

Reports & Metrics for UPF Formal Checks.

Reports and metrics

Reports & Metrics for UPF Formal Checks focuses on formal LP property pass rate, unreachable isolation condition count, and retention proof completeness. The goal is to link observed behavior to power-intent mechanism, ownership, and release risk.

Reports must translate formal LP property pass rate, unreachable isolation condition count, and retention proof completeness into release decisions. Totals are insufficient; you need transition context, ownership status, and closure trend.

Track formal LP property pass rate, unreachable isolation condition count, and retention proof completeness per transition, domain, and subsystem.
Report policy binding status with each metric movement.
Track open waivers with age and owner to avoid silent risk drift.
Store metric snapshots next to reproducible revision tags.

Low-power deep dive

Transition-centric verification closes LP risk better than active-mode-centric regressions.

Mini case study

Coverage looked high, but one untested OFF->RUN transition hid a restore race.

Debug branches

Rank by transition criticality
Correlate PMU logs with failures
Escalate unproven properties

Senior review question

Ask: what transition evidence proves this topic is closed, and which owner signs it?

Key takeaways

State transition context must accompany every low-power metric claim.
Intent changes require simulation, formal, and implementation re-validation.

Common pitfalls

Comparing results from mismatched UPF revisions.
Assuming static checks replace transition validation.
Shipping with aged waivers and unclear ownership.

Execution drill pack 1

Use this pack to rehearse low-power closure on low-power/low-power-verification/upf-formal-checks/reports: transition framing, policy ownership, implementation evidence, and release confidence.

Transition checklist

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.

Review prompts

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?
