Trace V4's scored misses to missing semantic premises while preserving the official failed result. The reports commonly identify the right risk and even the right witness, but close the proof with an uncited reading of syntax. In Boolean-configuration reports, a missing premise for implicit return or the end of main fans out into nine uncovered atoms; one official scoring path also accepted an equivalent omission and is recorded as an evaluator false pass. In length reports, agents use field types, usize subtraction, overflow behavior, or the fact that a true branch skips its else branch without authority that entails those exact propositions. In redesign reports, agents produce a sound witness and useful API but omit the premise that an ordinary safe function call imposes no unsafe caller obligation. The recurring defect is a proof kernel with an unstated root, not lack of a longer construct checklist. It motivates V5's distinction between artifact facts and semantic propositions, proposition-level provenance and consumer tracking, implication-direction checks, valid-use certificates, root-blocker fan-out, and mandatory disclosure of proofs reconstructed during review. Also harden later evaluations: score direct decisions separately from dependency fan-out, include metamorphic holdouts that vary syntax while preserving semantics, canonicalize retry and output handling, materialize gates mechanically, and define a finite terminal confirmation sequence rather than an open-ended search for ever more fixtures. gherrit-pr-id: Gquwn2yzvxejg4lkqiqoaaowxzxbmj62x Agent-Authored-By: AI agent acting on Josh Liebow-Feeser's behalf

Trace V4's scored misses to missing semantic premises while preserving the
official failed result. The reports commonly identify the right risk and even
the right witness, but close the proof with an uncited reading of syntax.
In Boolean-configuration reports, a missing premise for implicit return or the
end of main fans out into nine uncovered atoms; one official scoring path also
accepted an equivalent omission and is recorded as an evaluator false pass. In
length reports, agents use field types, usize subtraction, overflow behavior,
or the fact that a true branch skips its else branch without authority that
entails those exact propositions. In redesign reports, agents produce a sound
witness and useful API but omit the premise that an ordinary safe function call
imposes no unsafe caller obligation.
The recurring defect is a proof kernel with an unstated root, not lack of a
longer construct checklist. It motivates V5's distinction between artifact
facts and semantic propositions, proposition-level provenance and consumer
tracking, implication-direction checks, valid-use certificates, root-blocker
fan-out, and mandatory disclosure of proofs reconstructed during review.
Also harden later evaluations: score direct decisions separately from
dependency fan-out, include metamorphic holdouts that vary syntax while
preserving semantics, canonicalize retry and output handling, materialize gates
mechanically, and define a finite terminal confirmation sequence rather than an
open-ended search for ever more fixtures.
