+- `Low`: a small, localized, or behavior-preserving change. Mechanical changes

+- `Medium`: a bounded behavior change or small feature affecting no more than 20

+- `High`: more than 20 materially changed files with non-mechanical changes; a
+  large or cross-module feature; substantial domain or business-rule changes;
+  or changes affecting security, authorization, personal data, payments,
+  migrations, transactions, concurrency, data integrity, or public contracts.
 
-If the task has no GitHub link or issue link, pass only:
+Generated files, snapshots, and lockfiles do not raise risk by themselves. A

+For `High`, spawn one sub-agent without inherited conversation context. The
