Can a new reviewer reach the relevant source and reproduce the stated decision with fewer clarification rounds?
An evidence-navigation checklist records the exact source, command, expected output and unresolved question.
What we could measure together
Measure: Time to independently reproduced decision among successful reviewer attempts (minutes/review).
Freeze all eligible reviewer attempts and cutoff. Record success, failure and unfinished status, including the reason and age; time-to-success is conditional and never substitutes for completion rate.
Acceptance boundary: A successful hash check is custody evidence; independent reproduction and customer value require separate receipts. Retain every failed and unfinished review; no speed improvement claim if completion or decision correctness worsens.
