known_gaps:
  - Branch protection behavior depends on repository host, ruleset precedence, bypass permissions, merge queue settings, required review rules, and whether checks are tied to exact app names.
  - A failing required check may be caused by a missing workflow, skipped job, renamed check, stale merge base, branch restriction, or an actual test failure.

## TL;DR

Branch protection and required status checks tell agents whether a code change is mergeable, blocked by policy, or waiting on a specific CI signal.

## Core Explanation

Code agents often reach the point where a patch is correct locally but cannot be merged. The reason may not be the code. Repository policy can require passing checks, reviews, signed commits, merge queues, protected branches, or specific actors before a branch can land.

Useful evidence includes repository host, target branch, branch protection rule, required check names, latest check run IDs, pull request head SHA, merge base, required reviews, bypass permissions, merge queue state, and whether a check is missing, skipped, pending, failed, or stale. Without that context, an agent may rerun the wrong workflow or change code when the blocker is policy configuration.

Agents should separate technical failures from merge governance. A failed required test deserves debugging; a missing required check may need workflow wiring; a protected branch rejection may require a pull request or reviewer rather than a direct push.
