From deb5ff4536cdd2f960faba686e35b4b4c4443250 Mon Sep 17 00:00:00 2001 From: MSCodeBase Agent Date: Wed, 11 Nov 2026 00:38:57 +0300 Subject: [PATCH 1/5] fix(search): refuse only when no identifier occurs `_abstains` decided "the subject does not occur" from the FIRST extracted identifier. On commit prose that token is a dotted annotation or a type name, so the answer was emptied while a later name occurred hundreds of times: _orm.registry=0 Declarative=785 Databricks=0 TypeError=290 _orm.relationship.primaryjoin=0 omit_join=47 On the 40 solvable sqlalchemy commits 13 answered nothing this way (32.5%), and with the rows shown the gold was in the top-5 for 8 of them. The fix abstains only when NO identifier occurs. The policy is untouched: an answer whose tokens are all absent is still withheld (2 of the 13 stay refused). sqlalchemy, 40 commits hit@5 11 -> 17 (bar >= 15) B1 dev, 71 commits 19/71 unchanged (bar 19) 44 negative tasks 44/44 silent (bar 0 leaks) 13 formerly-empty 6/13 recovered (bar 8 - FAILED) P4 was miscalibrated in the frozen spec: the bar came from an include_neighbours=true run, which bypasses the refusal, while the change keeps it; the two remaining refusals are the all-zero case, so the maximum is 11/13. The gate is recorded as failed and not edited afterwards; the frozen decision rule ("P4 < 8 -> revert") and the measurement (P1 +6, no leak) disagree, so the ship decision is with the owner.

The E73 frozen spec gets a dated postscriptum: the P4 bar (>= 8/13) was derived from an include_neighbours=true run, which bypasses the refusal the change keeps; two of the thirteen commits have every identifier at zero and must stay refused, so the reachable maximum is 11/13. P4 stays FAIL in the run log; the bar is not re-edited and the number is not re-derived. 2. A regression test for the case the policy exists for: when every identifier is absent, the answer has no rows, says abstain, and hands back the exact `next: investigate(...)` call. The stub fails `has_symbol`, so the fail-open rule does not apply.
