Cymule TypeScript SDK

This package authors cymule.ir/2 Plan Candidates and calls a trusted Cymule Engine. It does not implement canonical sealing or runtime semantics.

FlowBuilder.definition() adds a reusable definition to the same immutable Plan and invoke() calls it with explicit input and result binding. Logical latest-compatible registry resolution is performed by the Rust M4 linker before sealing, never by the SDK.

npm install cymule

import { CliEngine, FlowBuilder, ResourceBuilder } from "cymule";

Resource Candidates use the same Engine boundary:

const resource = new CliEngine("./target/debug/cymule").sealResource(
  ResourceBuilder.text("input for another Run"),
);

Use ResourceBuilder.external for content-addressed/version-pinned objects, directories, collections, snapshots, and live references. Concrete access stays behind resolver plugins; Resource Candidates never contain credentials.

WaitActivationBuilder creates provider-neutral signal or timer delivery records. CliEngine.verifyWaitActivation validates the closed wire contract; the durable runtime remains responsible for matching pending waits and admitting the activation through CAS.

VirtualWorkControl is a transport-neutral interface for querying identified M3 attempt occurrences and submitting owner/work/lease/time-fenced resolution commands. VirtualWorkControlBuilder creates success, retry, failure, and cancellation commands without choosing a scheduler or worker transport. The same interface accepts adapter-produced region split/merge plans with opaque cursor preconditions and coverage evidence; SDK code never partitions cursor strings itself. It also carries completed-region compaction and exact-occurrence rehydration commands. VirtualArchive is only an immutable byte seam; the Rust controller computes and verifies manifest and certificate identity before M1 admission.

VirtualSchedulingControl carries capacity-slot claims, lease renewals, explicit expired-claim recovery, and future Run-weight updates. Builders require work and lease fences plus logical Clock values; they never run a worker loop or infer expiry from JavaScript time.

The package is published from GitHub Actions with npm trusted publishing and provenance. The Rust Engine remains the semantic authority.
