Release notes – v0.8.0

Release date: 2026-03-19

Summary

Long-lived TCP graph worker (daemon), gateway routing for CLI and MCP, worker CLI commands, CI, README/docs refresh, and LSP update guidance in INSTALL.

Features

  • Worker: sysmledgraph worker start [--detach] | stop | status; TCP NDJSON daemon (src/worker/daemon.ts) with serialized dispatch, worker.port + worker.lock, shutdown RPC and signals.
  • Gateway: src/worker/gateway.ts — long-lived TCP → optional stdio worker → in-process; MCP and graph artifacts use it when worker.port or SYSMLEGRAPH_WORKER_URL is set.
  • Socket client: ensureLongLivedClient / requestLongLived with optional reconnect when not SYSMLEGRAPH_WORKER_STRICT=1.

CLI & scripts

  • graph export / graph map; npm export-graph / generate-map delegate to CLI (gateway-aware).
  • scripts/index-and-query.mjs uses gateway + merged graph.kuzu and SYSMEDGRAPH_STORAGE_ROOT.
  • Worker exit codes: worker start 2 if already running; stale worker.port + live PID handling; worker status reports stale port file.

Tests & CI

  • npm run test:daemon — Vitest e2e (vitest.e2e.config.ts), worker + concurrent RPC smoke; fileParallelism: false for global storage root.
  • .github/workflows/ci.yml — Windows, Node 20: npm ci, build, test, test:daemon.

Docs

  • README: Versioning, env vars, full command tables, MCP tools/resources, CI link.
  • docs/INSTALL.md: Updating sysml-v2-lsp; editor highlighting vs language server.
  • docs/MCP_INTERACTION_GUIDE.md, docs/PLAN.md, docs/DESIGN_LONG_LIVED_WORKER.md, PLAN_IMPLEMENT_LONG_LIVED_WORKER.md — worker alignment.

Security / repo hygiene

  • .npmrc removed from version control (belongs in .gitignore only). If it was ever pushed with a token, rotate that npm token at npmjs.com.

Upgrade

npm install sysmledgraph@0.8.0
cd node_modules/sysmledgraph && npm run setup-lsp
npm run build   # from source clone

Optional: sysmledgraph worker start --detach with shared SYSMEDGRAPH_STORAGE_ROOT for CLI + MCP without Kuzu lock conflicts.

Later releases: release-notes-v0.8.1.md, release-notes-v0.8.2.md.
