@lenso/process-protocol

Runtime-neutral TypeScript types, strict JSON decoding, proof framing, and conformance helpers for lenso-process-jsonrpc-http-v1. The package also exports transport-neutral Authoring V2 values and validators; Process and Bun adapters supply their own envelopes.

Execution Adapters and child SDKs use this package at their wire boundary. It does not spawn processes, open HTTP listeners, generate random secrets, perform HMAC, interpret Capability payloads, or own Plugin behavior.

Execution target capability profiles

execution-target-capability-profile-v1.schema.json and the exported ExecutionTargetCapabilityProfile helpers define a versioned, closed declaration for one exact Adapter or Driver runtime profile. The supported V1 feature names are request, stream, event, websocket, host-imports, native-process, wasm-component, remote, browser, and workers.

Profiles are explicit: a target_profile name grants no inferred behavior. Hosts compare the declared capabilities against the selected implementation's needs before dispatch. Unknown features, missing capability lists, invalid profiles, and undeclared requirements fail closed. The capability list is canonical-sorted and unique; an empty list intentionally declares no V1 features.

The profile contract describes target behavior only. It does not select a Plugin provider, change an immutable Resolved App Plan, or decide Host policy.

The published schemas/process-protocol-v1.schema.json describes every V1 request and successful-response envelope. Runtime validators additionally enforce constraints JSON Schema cannot express, including duplicate-key rejection, canonical array ordering, and expected identity/session equality.
