Analyze why the V4 focused gate failed - #3535
Conversation
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

There was a problem hiding this comment.
The preserved artifacts do not currently pass the repository's own integrity check: running python3 protocol.py verify-static in this run raises ValueError: preserved attempt changed: r021/1, and direct comparison also finds mismatched event digests for failed attempts r023/1 and r047/1. Either repair those records or disclose the integrity limitation; otherwise this status section incorrectly assures readers that the evidence chain validates.

Report F did close the len return-type premise: its AX-LEN entry explicitly states that bytes.len() returns the element count as usize, and the frozen adjudication passes L3 on exactly that basis (scoring/adjudications/L.json). Its actual missing numeric leaves were the usize domain, subtraction, and overflow/profile semantics. Grouping it with E as also missing the return type makes this root-cause analysis inconsistent with the preserved adjudication and should be narrowed accordingly.

There was a problem hiding this comment.
The frozen L adjudication records three unresolved rubric ambiguities that directly affect scoring: whether an opposite-direction quotation also fails L2/L6, when such an extraction gap triggers LH4/G11, and whether F's alternative positivity derivation satisfies L3. Isolated certificate tests do not define those decision rules, so singling out only the P ambiguities leaves the next evaluation able to reproduce the same inconsistent L scoring; add explicit resolutions for the recorded L cases before collection.

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.
