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.
Enable Wasmtime's persistent compilation cache and expose an optional cache directory in RuntimeConfig.
Create and canonicalize the configured directory before Engine construction, and report cache filesystem and configuration failures through dedicated RuntimeError variants.
Introduce an injectable, deadline-aware KvBackend boundary and link only the exact wasmeld:kv/store@0.1.0 import requested by a Component.
Namespace entries by service ID so revisions share state while services remain isolated, reject registrations without a backend, and enforce 256-byte keys and 64 KiB values.
Cover capability discovery, cross-revision sharing, service isolation, missing backends, and resource limits with Component integration tests.
- 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
