Power Bug Triage: Review Checklist

Review Checklist for Power Bug Triage.

Review checklist

Review Checklist for Power Bug Triage is anchored on illegal transition rate, corruption incidence, and deterministic replay quality under low-power scenarios. Convert observations into mechanism-backed and owner-bound actions.

  • Scope, mode, seed, and metadata are explicit.

  • Mechanism classification is evidence-backed.

  • Ownership and rollback boundary are documented.

  • Validation matrix includes deterministic replay checks.

  • Owners signed: LPV lead, power-intent owner, LPV Debug & Signoff owner.

Low-power verification deep dive

Signoff confidence comes from triage discipline, reproducible proof, and explicit residual-risk decisions.

Metrics and artifacts to collect

  • X-prop triage classification report

  • bug root-cause closure packet

  • regression stability and recurrence trend

  • signoff checklist completion matrix

Mini case study

A signoff block cleared after the team replaced broad waivers with boundary-specific evidence and replay criteria.

Debug branches

  • Classify X behavior before broad waiving.

  • Capture one definitive artifact packet per closure claim.

  • Define residual risk and rollback path at signoff.

Senior review question

Ask: what exact low-power transition boundary failed first, and which artifact proves the closure claim reproducibly?

Key takeaways

  • Tie each LPV claim to a concrete transition boundary and one proving artifact.

  • Prefer minimal reversible fixes with explicit owner and rollback criteria.

Common pitfalls

  • Treating power-aware failures as random before boundary classification.

  • Waiving X-prop failures before proving impact and root cause.

  • Declaring closure without deterministic replay across key modes.

Principal LPV review addendum

Power Bug Triage should be reviewed as a transition integrity system, not just isolated checks.

Use illegal transition count, corruption incidence, and reproducibility of low-power regressions across fixed seeds as alarm and LPV evidence packet: transition timeline, assertion outcomes, and before-after replay summary as proof.

LPV debug and signoff require disciplined triage: classify X behavior, isolate root cause, and close with reproducible evidence. Closure quality comes from reproducible evidence and explicit owners.
