  "summary": "Builds a phased strangler-fig migration/modernization plan for legacy frontend stacks (jQuery/Backbone/AngularJS, old bundlers, framework major versions) with rollback gates, exit criteria, and business-risk-first sequencing, loading legacy-pattern, risk, and rollback references progressively rather than dumping the whole migration playbook into every prompt.",

  "security_notes": "Never propose a migration phase that merges auth/session state across old and new stacks without a named security review gate. Treat every phase's rollback path as a hard requirement, not optional documentation.",
