From 934b778c9d8e2b4bcf6eac9540981cec5421873c Mon Sep 17 00:00:00 2001 From: Vic Gupta Date: Fri, 30 Oct 2026 14:59:58 -0400 Subject: [PATCH] Verify-on-stop: inferential review tier after computational checks (#250) Adds verify_on_stop.review / --verify-review: once every computational check passes at stop, the model is asked once, without tools, to review the run's file changes. Findings are report only (verify.review event, stderr, trajectory verify_review).
