+# Loop Catalog

+This page defines reusable loops for AI-assisted software engineering.

+
+## Feature loop
+
+Goal -> acceptance criteria -> design -> implement -> verify -> document -> done.
+
+## Bug loop
+
+Reproduce -> failing test -> root cause -> minimal fix -> regression -> done.
+
+## Refactoring loop
+
+Baseline -> characterization tests -> small change -> verify -> repeat.
+
+## CI/CD loop
+
+Logs -> classify -> root cause -> patch -> verify -> rerun CI.
+
+## Infrastructure loop
+
+Plan -> validate -> review risk -> approve if needed -> apply to lower environment -> smoke test.
+
+## Security loop
+
+Threat -> control -> abuse case -> verify -> residual risk.
+
+## Performance loop
+
+Measure -> hypothesize -> change -> benchmark -> keep or rollback.
