2026-07-14 (research): ADOPTED pre-registration of acceptance criteria — hash + timestamp at spec time, BEFORE any code. The novelty claim is that abcd writes the specification before the code exists, which is exactly the defect that killed SWE-bench Verified (35.5% of audited tasks demanded implementation details never stated in the problem) and SWE-bench Pro (retracted 2026-07-08). Without a commitment artefact the claim is unprovable and CANNOT be retrofitted — every intent shipped without it is lost evidence. The primitive exists (receipt_id already hashes the AC section, excluding Audit Notes).
