# yoi-plugin-runtime
|
||||
|
||||
Runtime-owned, standalone execution of exact v2 Tool Components. [`Executor`] compiles only artifacts reverified through `manifest::plugin`, then creates a fresh Store and instance for each invocation. It does not resolve catalogs, config, Worker plans, delivery caches or repository paths, and does not register Tools with a Worker.
|
||||
|
||||
[`host`] is an explicit asynchronous injection boundary, not an implementation of Server authority or HTTPS. Every invocation (including pure computation) requires live admission and result-publication authorization. Providers must bind their authenticated installation/plan/subject and narrowed grants to [`host::InvocationContext`], authorize every protected operation, and make pending work cancellation-safe. There is no default provider or product allow-all fallback. Dropping a provider future must release temporary resources; an already dispatched external effect is not rolled back. Durable effect receipts, secret resolution, URL/DNS/TLS policy and real network transport belong to the Host provider, not this sandbox.
|
||||
|
||||
Component instantiation is not a Tool export: all Host imports, including logging, are rejected until the export context is installed. Service start/stop semantics are outside this crate. Only exact WIT imports are linked, without WASI, filesystem, environment, process, clock or network ambient authority. Call-local connection resources hold opaque provider objects; guest resource representations never identify a Server resource or issue a grant.
|
||||
|
||||
A single deadline covers admission, instantiation, guest execution, asynchronous Host waits, post-return and publication. Fuel bounds computation and cooperatively yields; epoch interruption cooperatively yields as well. Store memory/table/instance limits, call-local resource and operation counts, serialized payload and diagnostic budgets complement those bounds. Text/JSON overflows fail rather than returning truncated success; excess diagnostic entries are dropped and counted. Guest diagnostics are untrusted, must not contain secrets, and are separate from model output. Host adapters must not log raw request/response or credentials.
|
||||
|
||||
The Tool sandbox accepts only imported Host resources. Wasmtime's Store limiter does not meter guest-defined Component resource tables, so compile rejects private resource definitions and canonical `resource.new` throughout concrete nested Components before any Store exists. This is an additional execution-policy restriction after shared package/ABI verification, not a second package validator. It preserves the WIT connection imports, whose creation is metered by the adapter, without claiming a quota for unmetered internal resource allocators. Unsupported execution policy is distinct from corrupt artifact identity.
|
||||
|
||||
Compile results may be shared, but invocation memory, resource tables and imported state are never shared. The caller owns finite aggregate admission/concurrency quotas; per-invocation limits alone do not bound an unbounded number of callers. A validated digest is content identity, never admission authority. This standalone core is not connected to normal Worker launch/restore; product integration must supply the live Server provider.
