+# Check: required-status-check rulesets reference current names

+# After centralizing workflows into reusables (#87, #88), GitHub composes
+# check names as `<caller-job-id> / <reusable-job-id-or-name>`. Repos
+# that updated their workflow files but didn't update their rulesets
+# are silently broken — the merge gate references a name that no
+# longer exists, so it can never be satisfied.
+#
+# Inspects both the new ruleset system and classic branch protection.
+# Flags two distinct problems:
+#   1. Stale pre-centralization name (e.g. `claude`, `AgentShield`)
+#      → emit "stale-required-check-<old-name>"
+#   2. `claude-code / claude` listed as required
+#      → emit "required-claude-code-check-broken" because that check
+#        is structurally incompatible with workflow-modifying PRs
+#        (claude-code-action's app-token validation refuses to mint
