From bec76d48895ad0ae14ade272f3723475838b903b Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 25 Jul 2026 14:25:31 +0000 Subject: [PATCH] fix(evals): carry hash_surface on the CaseResult the register matrix actually uses MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Corrects bf17f42, which claimed a fix that did not work. That commit added hash_surface to evals/cognition/runner.py::CaseResult. The test imports run_eval from evals/run_cognition_eval.py, which builds evals/metrics.py::CaseResult — a DIFFERENT class with the same name. Thirteen files in this repo define one. I matched on the class name instead of following the import, so the field never reached the assertion and _diff_rows raised AttributeError: 'CaseResult' object has no attribute 'hash_surface'. That is why the count went 99 -> 100: the same 99 divergences, plus one error. The diagnosis in bf17f42 was right; only its aim was wrong. Confirmed directly at the pipeline seam: register=None surface = 'Truth is what is true. pack-grounded...' hash_surface = 'Truth is what is true. pack-grounded...' register=socratic_v1 surface = 'Consider the question: Truth is what is...' hash_surface = 'Truth is what is true. pack-grounded...' surface varies across the register axis (as it must), hash_surface does not (as it must not), trace_hash matches. So the field added to CognitiveTurnResult in bf17f42 is correct and stays; this moves the eval-side plumbing to the class the test really consumes, and reverts the edit to the one it does not. [Verification]: PARTIAL. Three registers green — socratic_v1, terse_v1, manifesto_v1, 24 passed, where all three failed before. The full 99-register run (~17 min) was still executing when the tree had to be committed; result to follow, and bf17f42's DO NOT MERGE stands until it is green.
