Problem

The triage agent creates a throwaway branch for debug instrumentation (console.log, verbose logging). If the agent crashes or times out, the branch is left behind polluting the repo.

Fix

Add a trap in the triage entrypoint path (or the formula runner) that deletes the throwaway branch on any exit:

DEBUG_BRANCH="triage-debug-${ISSUE_NUMBER}"
trap 'git -C "$PROJECT_REPO_ROOT" checkout "$PRIMARY_BRANCH" 2>/dev/null; git -C "$PROJECT_REPO_ROOT" branch -D "$DEBUG_BRANCH" 2>/dev/null' EXIT

Same pattern as the stack lock trap already in entrypoint-reproduce.sh.

Files

docker/reproduce/entrypoint-reproduce.sh — add branch cleanup to the exit trap
Or: formulas/triage.toml — instruct Claude to register the cleanup in its first step
