Debug Playbook for UPF Object Model focuses on UPF lint violations, unresolved object references, and policy binding success. The goal is to link observed behavior to power-intent mechanism, ownership, and release risk.
Low-power debug is timeline-centric. Find the first transition deviation, then trace policy and ownership from intent to implementation.

state model + waveform timelineFreeze failing RTL, UPF, PMU sequence, and implementation tags.
Identify the first failing transition and affected crossing.
Classify issue: policy binding, sequencing, or physical realization.
Prove mechanism with one reduced reproducer.
Patch smallest owner-controlled fix.
Re-run focused checks then full LP regression matrix.
LOW-POWER REVIEW MEMO — Power Intent Fundamentals / UPF Object Model
1. Symptom
- Watched metric: UPF lint violations, unresolved object references, and policy binding success
- Failing transition: <state_from -> state_to>
- Failing crossing/domain: <source -> destination>
- Revision tags: <RTL, UPF, PMU sequence, implementation>
2. Mechanism hypothesis
- Primary mechanism: UPF objects (domains, supply nets, sets, strategies, controls) form a graph that tools resolve from RTL through implementation.
- Competing hypotheses: <intent mismatch, sequence bug, physical issue>
- Missing evidence: <coverage, waveform bookmark, signoff report>
3. Proposed action
- Minimal reversible change: <policy/sequence/implementation patch>
- Expected movement: <coverage, violation count, transition pass rate>
- Regression risk: wake-up timing, X-leak, IR droop, retention stability
4. Signoff
- Re-run artifact: UPF lint log, object resolution report, and policy summary
- Required owners: UPF owner, CAD owner, integration lead
- Final decision: fix, bounded waiver, or escalationPower intent must be explicit, reviewable, and tool-consistent from day one.

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.
