-3. **Validation:** For search results, read the first 20 lines and verify the project, feature and current branch. A mismatch means "no plan file found." Conversation-supplied paths bypass this search-result check.
+\`PLAN_CANDIDATE:\` lines are repo-committed \`docs/designs/\` files this branch changed or that name the branch, then personal plan files that name it. Offer them with AskUserQuestion: one option per candidate (at most four), plus "No plan: skip the audit". Recommend the candidate only when exactly one \`docs/designs/\` file changed on this branch; otherwise recommend skipping. Spawned or non-interactive runs take the recommendation. Read the chosen file's first 20 lines to confirm the project and feature.
