Ticket #55 PR #12 Review: pass_audit transition approved Implementation approved for workflow fixes: - pass_audit: review → pending_approval (ticket.rb:81) - fail_audit: in_progress → todo with has_reviewer_comment? guard (ticket.rb:89-90) The comment validation uses AASM guard pattern correctly: def has_reviewer_comment? comments.code_reviews.any? end Tests cover both success (with comment) and failure (without comment) cases. Key pattern: Use guard: with method returning boolean for AASM transition validation.
