Case
- Goal

- Packages

fastify 5.12.0
- Environment

Contract
- assert Fastify 5.12.0 encapsulates decorators and scoped error handlers within registered plugin contexts so they do not leak to root or sibling plugin instances
- assert lifecycle hooks registered inside an encapsulated plugin execute only for routes within that plugin scope while root hooks execute for all routes
- assert errors thrown inside an encapsulated plugin are handled by the scoped error handler while root errors fall back to Fastify default 500 error response
- assert app.inject executes all scoped requests in process without opening a listening socket
