Case 06: Numerical polynomial-time Artin membership

Self-authored synthetic review scenario, not a published software claim or customer assertion. The source material is public and pinned to fd4aeeb2ee4fc729c18d98444fed42fd0529eeeb.

Proposed claim

A numerical coefficient backend is independently verified to implement polynomial-time membership in every finite-rank Artin parabolic.

Review the declared model and statuses against the source. Cases 09/10 deliberately supply synthetic statuses to test documentary completeness. Those statuses are not authenticated evidence or proven hypotheses. Other cases explicitly leave operational obligations unknown.

Pointers identify exact files, not a new complete-file reading, theorem proof or selected-run certificate. Determine the statement, hypotheses, formal coverage and missing model/implementation bridges from the source itself.

Record preparation seconds, material gaps with exact evidence locations, unsure items, false alarms after adjudication and correction seconds in the blank result template. Do not open the report/key during the source-only arm. No expert has completed either arm.
