LangGraph (Python) adapter for vsl-core: implements the VSLAdapter conformance contract and provides gated_node/route_on_denial to call a compiled gate before a StateGraph node runs and route around a denial. Ledger writes and Fallback retry logic stay in your own code — governance vocabulary lives in vsl-core. Alpha, MIT.

LangGraph.js adapter for @supersemantics/vsl-core (TypeScript port of VSL-Core): implements the VSLAdapter conformance contract and provides gatedNode/routeOnDenial to gate a node before it runs and route around a denial. Ledger writes and Fallback/retry logic are not handled here — policy vocabulary stays in vsl-core. Alpha, MIT, not yet on npm.

TypeScript HTTP client (RemoteLedgerStore) implementing vsl-corejs's LedgerStore interface against ledger-api, the hosted paid backend for VerbaLedger — so a ledger can write to a durable, multi-tenant store instead of a local file. No dependency beyond vsl-core (uses built-in fetch). Alpha, MIT, not yet on npm.

Python HTTP client (RemoteLedgerStore) implementing vsl-core's LedgerStore Protocol against ledger-api, the hosted paid backend for VerbaLedger — so a ledger can write to a durable, multi-tenant store instead of a local file. Kept separate to keep vsl-core dependency-free. Alpha, MIT.

TypeScript port of vsl-core: the same VSL governance vocabulary (PreNode, Invariant, AssuranceBasis, VerbaLedger, Cluster) for Node/TS agent frameworks, without a Python runtime. Framework-agnostic, zero runtime dependencies. Python vsl-core remains the reference implementation. Alpha, MIT, not yet on npm.

LangChain adapter for vsl-core: implements the VSLAdapter conformance contract and gates tool calls inside a create_agent() agent via VSLToolMiddleware (wrap_tool_call). Ledger writes and Fallback retry logic stay in your own code — governance vocabulary lives in vsl-core. Requires LangChain >= 1.0. Alpha, MIT.

Microsoft Agent Framework adapter for vsl-core: implements the VSLAdapter conformance contract and provides VSLFunctionMiddleware, gating every tool call an Agent makes before it fires. Ledger writes and Fallback retry logic stay in your own code — governance vocabulary lives in vsl-core. Alpha, MIT; real-Agent path not yet end-to-end tested.
