Development record

The build chapter lists its checks by name and says a refusal names the check (.abcd/development/brief/04-surfaces/34-build.md:40-48,134). An issue id the repository's drain rule does not take is refused at a check named `eligible` (internal/core/implement/loop/check.go:41). The key bullet describes that rule at line 44 without the name, so a reader holding the refusal cannot find the check under the name it gives.
