testkit

@graphorin/channels/testkit - conformance suite + in-memory building blocks for adapter authors and application tests.

Interfaces

Interface	Description
ConformanceHarness	Hooks the suite uses to drive the adapter under test. `sendInbound` must make the adapter produce ONE inbound message (for a real vendor adapter: through the vendor fake; the loopback adapter's `inject` satisfies it directly).
ConformanceTestApi	The subset of the vitest/jest API the conformance suite needs - injected so this module has no test-framework dependency.
LoopbackAdapter	The in-memory loopback adapter: a full `ChannelAdapter` whose transport is the test itself. Tests `inject()` inbound messages and read `deliveries` for what the gateway sent back.
LoopbackAdapterOptions	Options for createLoopbackAdapter.
LoopbackInboundInput	Convenience shape for LoopbackAdapter.inject.

Function	Description
createInMemoryPairingStore	In-memory `PairingStore` for tests and single-process prototypes. Mirrors the sqlite implementation's semantics (one pending request per peer, per-channel code uniqueness by construction).
createLoopbackAdapter	Build a loopback adapter for tests and prototypes.
describeChannelAdapterConformance	Register the conformance suite against a harness.
