Run a preregistered 150-report forward evaluation: ten modes, three frozen conditions, and five fresh replicates per cell, with two blind scorers per mode and adjudication before unblinding. V2 versus V1 is the primary comparison; the V1 core ablation is only a historical bridge. V2 passes every whole-execution, exact Rust-1.79/1.80 boundary, producer-quantifier, ticket, configuration, and published-contract atom. It produces no proposal laundering and retains strong reconstructed-proof behavior. The release gate still fails with 16 atom misses and five hard errors. Four of five V2 reports contract an inclusive stable-release interval by omitting Rust 1.80.1, then assert exhaustive closure. Another report assembles every fact needed for a valid empty-slice UB witness but dilutes the conclusion to UNPROVED by continuing to seek a universal positive lemma. Sparse-version interval claims cause two more misses; one omitted alias route exposes an oracle-granularity issue rather than a clear skill defect. The evidence shows that recovering the quantified domain must itself be a proof obligation and that verdicts need explicit logical certificates. It motivates V3's Required/Covered model, domain-transformation obligations, multi-release proof bases, and existential UB certificate. Preserve the failed gate unchanged. Differences between coherent conditions are mixed, modes are heterogeneous, five replicates are an engineering screen, and procedural isolation and unavailable model/seed identity preclude a broad causal or population-level claim. gherrit-pr-id: Gthyz3viupsc7cxzrbqaql6qitqmx2ews Agent-Authored-By: AI agent acting on Josh Liebow-Feeser's behalf

Run a preregistered 150-report forward evaluation: ten modes, three frozen
conditions, and five fresh replicates per cell, with two blind scorers per mode
and adjudication before unblinding. V2 versus V1 is the primary comparison; the
V1 core ablation is only a historical bridge.
V2 passes every whole-execution, exact Rust-1.79/1.80 boundary,
producer-quantifier, ticket, configuration, and published-contract atom. It
produces no proposal laundering and retains strong reconstructed-proof
behavior.
The release gate still fails with 16 atom misses and five hard errors. Four of
five V2 reports contract an inclusive stable-release interval by omitting Rust
1.80.1, then assert exhaustive closure. Another report assembles every fact
needed for a valid empty-slice UB witness but dilutes the conclusion to
UNPROVED by continuing to seek a universal positive lemma. Sparse-version
interval claims cause two more misses; one omitted alias route exposes an
oracle-granularity issue rather than a clear skill defect.
The evidence shows that recovering the quantified domain must itself be a
proof obligation and that verdicts need explicit logical certificates. It
motivates V3's Required/Covered model, domain-transformation obligations,
multi-release proof bases, and existential UB certificate.
Preserve the failed gate unchanged. Differences between coherent conditions
are mixed, modes are heterogeneous, five replicates are an engineering screen,
and procedural isolation and unavailable model/seed identity preclude a broad
causal or population-level claim.
