CPF vs UPF is a core part of Power Intent Fundamentals. CPF and UPF express similar low-power intent with different constructs; migration quality depends on preserving domain policy semantics, not syntax. Senior engineers connect observed behavior to explicit state policy, domain boundaries, and sequence ownership before proposing fixes.
CPF and UPF express similar low-power intent with different constructs; migration quality depends on preserving domain policy semantics, not syntax.
Primary metric: intent migration completeness, semantic mismatch count, and review waivers
Primary artifact: migration checklist, side-by-side intent diff, and signoff waiver log
Owners: low-power lead, CAD owner, methodology owner
Legal state transitions must be explicit and testable
Every crossing requires policy + evidence
At product level, CPF vs UPF defects become intermittent, expensive silicon escapes. Power intent is an executable architecture contract.
MIGRATION CHECK
CPF construct -> UPF construct -> semantic parity?
domain defs -> create_power_domain
isolation -> set_isolation
retention -> set_retention
Syntax conversion is easy; behavior parity is the real work.Name the failing mode transition and power states.
Open intent migration completeness, semantic mismatch count, and review waivers and identify which crossing or policy failed.
Align waveform timeline with PMU control sequence.
Check UPF object binding and policy ownership.
Collect migration checklist, side-by-side intent diff, and signoff waiver log with database/view tags.
Classify: intent mismatch, sequencing bug, or implementation defect.
Apply minimal fix and rerun LP regression matrix.
If active mode passes, low-power behavior is safe.
Isolation alone can hide all OFF-domain issues.
Any UPF syntax conversion preserves semantics.
Static reports are enough without transition coverage.

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.
