Detect the resident actor export, route Host events through the bounded Actor mailbox, enforce fuel, deadlines, payload limits, and translate WIT effects into typed runtime values.
Add a revision-scoped ResidentSession with deny-by-default TCP, UDP, and Unix endpoint policies, non-reused resource IDs, stream lifecycle and backpressure state, atomic effect validation, timers, subscriptions, extension sources, and shutdown handling.
Cover passive rejection, real Component ABI round trips, resource ownership, endpoint policy, and driver operation validation with integration tests.
- add an exact-version Capability Registry and structured descriptors
- move Clock bindings, host state, and Linker installation into its own module
- derive required capabilities from Component imports and link only requested interfaces
- cover exact-version resolution and minimal per-component capability sets
- define versioned service and clock WIT contracts
- enforce import allowlists, fuel, epoch, memory, I/O, and mailbox limits
- keep one Store and Component Instance resident per serial Actor
- add echo, counter, fault, spin, and capability probe components
- cover lifecycle, concurrency, sandbox, and fault recovery behavior
