fix: keep follower debug wrapper visible

 When a repeated runtime pitfall or visibility defect is found during branch-follower work, update this reference or the skill entry first, then continue with the narrow debug step. Do not proceed to `run-once`, controller loop observation, automatic follower validation, or source-commit-driven integration until the relevant `state-read`, `status-read`, `decide`, and `state-write` debug steps pass for the affected follower.
 
+`debug-step` wrappers must be failure-visible and non-crashing. If the target-side Job fails, returns an older schema, or omits optional summary fields, the operator-facing CLI must render `-`/null plus the target error and Job identity; it must not throw a local TypeError before showing the target evidence.

 ## Source Authority
 
 - Follower decisions must not read host source worktrees, target dev directories, `.worktree/*`, local git state, or direct GitHub branch refs.
