pub fn external_verify_commands(project_root: &Path, phase: u32) -> Vec<String>Expand description
Return external verification commands declared by this phase’s plans.
Only the first YAML frontmatter block is inspected. This intentionally
small parser recognizes the scalar shape established by Phase 16:
external_verify: "command" (single-quoted and unquoted scalars are also
accepted). Runtime captures and agent output are never read here.
