From 0127fa99be11909906f41952467f404ed391c6dc Mon Sep 17 00:00:00 2001 From: Molecule AI CP-BE Date: Fri, 24 Apr 2026 18:24:05 +0000 Subject: [PATCH] fix(middleware): add missing return after AbortWithStatusJSON in CanvasOrBearer final else P0 (Audit #35): CanvasOrBearer final else branch calls c.AbortWithStatusJSON(401) without return, allowing the downstream handler to overwrite the 401 response. Regression tests added verifying handler is NOT called after abort in both no-cred and wrong-origin paths. Confirmed on origin/main @ a59f1a6c and origin/staging.
