From 16f7916eb4c1d79be45a3225812f39fe8cb462af Mon Sep 17 00:00:00 2001 From: Aaron Wong <6979793+zzwong@users.noreply.github.com> Date: Mon, 7 Sep 2026 21:26:30 -0400 Subject: [PATCH] fix: preserve valid reviewer coverage during output repair Treat repeated coverage claims as one claim and report out-of-assignment positions safely so correction attempts remain actionable.
