@x12i/lscp-core

Live Shared Context Protocol — application-layer schemas and helpers for shared human–agent workspaces (above MCP).

License: Apache-2.0
Version: 0.4.0

Context Graph compilation is Nexum (x12i-nexum/1). Nexum never writes product data; the LSCP host applies the plan. See @x12i/lscp-nexum and the shareable overview in the Thalux docs.

npm install @x12i/lscp-core

import {
  assertCanPropose,
  buildLscpToolDescriptors,
  CONFORMANCE_CHECKLIST,
  CONTEXT_GRAPH_CHECKLIST,
  neighborhoodQuerySchema,
  NEXUM_PROTOCOL,
} from "@x12i/lscp-core";

buildLscpToolDescriptors(); // Context Graph + connector tools included by default

What this package provides

• Zod schemas for ActorRef, grants, ActionRecords, Knowledge/Work objects
• Governance helpers (assertCanPropose, grant matching)
• Context Graph / Nexum types: NeighborhoodResult, NexumItem, drafts, apply plans, contributions
• MCP tool descriptors for LSCP, neighborhood/query, and push/pull/sync
• Conformance checklists (CONFORMANCE_CHECKLIST; CONTEXT_GRAPH_CHECKLIST is an alias of the Nexum Full items)

What it does not provide

• Persistence, Express routes, or Mongoose models (host-owned)
• Human authentication (reference host: Authix)
• Nexum compilation itself (see @x12i/nexum + @x12i/lscp-nexum)

Context Graph

Nexum is mandatory for LSCP-Full. There is no Graphifier path and no disable flag.

| Component | Role | | --- | --- | | @x12i/nexum | Pure compiler: records → draft + apply plan | | @x12i/lscp-nexum | Host bridge, ACL mapping, configured-AI semantics (fail open) | | LSCP host | Persist and apply; neighborhood reads the committed projection |

If the configured AI provider is unavailable, deterministic Nexum output still applies.
