aether-testkit

Reusable conformance checks and deterministic test doubles for Aether extension authors.

The suites verify live-state round trips and ordered batch reads, FIFO and acknowledgement behavior for durable outboxes, bounded/provenance-preserving HistoryQuery projections, and exact descriptor/request/result correlation for request-driven DataProcessor implementations. Processor conformance also checks finite ordered forecast output and requires unavailable responses to contain no derived output.

MemoryCloudLinkTransport::pair is the transport-neutral fake binding for session/replay tests. It emits transport-published evidence for durable sends but never invents a cloud application ACK, so tests must create the receipt explicitly.

ScriptedDataProcessor is a queue-driven DataProcessor test double. It reports a configurable health result, consumes queued ProcessingResult or PortError values in FIFO order, and retains the complete DataProcessingRequest values it received. Application, adapter, and example tests can therefore prove both the exact frame sent to a processor and the result/error path without a model runtime or network service.

Extension tests call the conformance helpers against concrete adapters so capability semantics remain consistent across local and external boundaries.
