Add a lifecycle-serialized unregister operation that stops a resident Actor before releasing its registered and compiled Component.
Return the existing not-registered and unavailable errors without leaving a partially removed live revision, and cover Actor and registration count cleanup.
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.
- 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
