Review verdicts assert verification that was never performed

Summary

Claude Code issues summary output whose form implies completed verification, when only part of the verification was done. The failure is not a knowledge gap: the model states a conclusion covering material it never examined.

What happens

Given a ~13,000-line pull request spanning 19 independent concerns, the model verified 5 of them against normative sources and then issued a single "accept as-is" verdict over the entire diff. In the same message it listed the 14 components it had not checked. The largest component in the change was among the unchecked ones - the pattern is that quick wins are verified first because they make the message feel finished.

The user's loaded instruction file contains the literal rule that a component with no citation means no verdict for the pull request, "not 'accept with a caveat', not 'unverified but disclosed'". The model had read that file at session start.

The verdict was withdrawn only after the user said the review looked lazy. Everything the second pass found was reachable in the first.

Why this matters

A verdict is a claim about the whole change. Partial verification presented as a global approval converts unverified code into apparently-verified code, in the assistant's voice, at the moment a human is deciding whether to merge. For a project whose value is that a wrong API shape never reaches main, this is the worst possible failure.

Expected

Treat required-step completion as a hard gate on emitting verdict-shaped output. Either verify every independent component, or decline to issue a verdict and name what remains open. Partial verification must not be expressible as a qualified approval.

Environment

• Claude Code CLI, Opus-class model, paid subscription
• Long sessions (6-8h) reviewing pull requests on an open-source cloud-service emulator
• Custom instructions supplied in both a project instruction file and a persistent memory directory, loaded automatically at session start
• Incidents are taken from transcripts recorded as they happened across three consecutive sessions, within a 90-day pattern
