CPF vs UPF: Review Checklist

Review Checklist for CPF vs UPF.

Review checklist

Review Checklist for CPF vs UPF focuses on intent migration completeness, semantic mismatch count, and review waivers. 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: low-power lead, CAD owner, methodology owner.

OWNERSHIP MAP — CPF vs UPF

artifact              owner
----------------      -----------------
intent policy       low-power lead
implementation      CAD owner
verification        methodology owner

Escapes happen when ownership is implicit.

Low-power deep dive

Power intent must be explicit, reviewable, and tool-consistent from day one.

Reports and artifacts

PST report
domain map
UPF lint
policy binding summary

Mini case study

One missing PST entry blocked legal retention mode and caused false debug loops.

Debug branches

Check legal state table first
Audit policy binding IDs
Freeze UPF revision tags

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.

Principal LP review addendum

CPF and UPF express similar low-power intent with different constructs; migration quality depends on preserving domain policy semantics, not syntax.

Metric: intent migration completeness, semantic mismatch count, and review waivers
