Comparator v3.1 Closure Report

Regression Status

PASS.

comparison/calibration/comparator-v3.1-regression-report.md records 33 total tests, 33 passed tests, 0 failed tests, and 0 blocking failures.

Run Consistency Status

PASS.

All generated v3.1 outputs were verified against one immutable run state: 179fa743-b92a-4f75-b4a2-492fa9eb7898.

The dq=5 shorthand is resolved as:

• 1 explicit tolerant_parse event for ECR-000003-EXP001-P001D GPT
• 4 dataset-level warning rows documenting tolerant parsing for GPT P001A through P001D

These are audit-visible data-quality events, not missing or malformed primary records. Dataset completeness remains 12/12.

Approval Scope

Comparator v3.1 is approved only for ECR-000003.

Approved experiments:

• ECR-000003 EXP-001
• ECR-000003 EXP-002
• ECR-000003 EXP-003

Comparator approval is not hypothesis validation.

Freeze Scope

Comparator v3.1 is frozen for ECR-000003 after limited approval.

• EXP-002 and EXP-003 must use the frozen instrument unless a documented blocking defect triggers a versioned emergency change.
• Future ECRs require adapter review.

Remaining Limitations

• Constraint reporting remains calibration-sensitive.
• Domain-leakage findings remain contextual and should not be treated as recognition proof.
• Future ECRs require adapter review.
• Comparator approval is not hypothesis validation.

EXP-001 EDR Readiness

EDR-ECR-000003-EXP001.md is ready for human completion with verified observations prefilled and interpretation/decision sections left open.
