Circuitarium MCP v0.3.1

[0.3.1] - 2026-07-28

Added

• Added doctor --json and doctor --smoke. The smoke mode creates one
  deterministic synthetic CRUMB fixture in an isolated operating-system
  temporary directory, starts a fresh stdio server, verifies all 22 tool
  registrations plus analysis and ERC results, and confirms cleanup without
  touching the caller's configured workspace.
• Added executable configuration tests for the documented MCP hosts, including
  a native-Windows cmd /d /s /c launch, and installed-package smoke jobs on
  Windows and macOS.
• Added public author metadata, CITATION.cff, a local-data privacy policy, an
  original application icon, and complete MCPB support, privacy, prompt, and
  tool-annotation metadata.
• Added an official MCP Inspector 2.0.0 release-evidence path that exercises
  every registered tool against independently authored synthetic artifacts,
  with optional version-pinned Logisim 4.1.0 runtime evidence.
• Added a narrow starter-workspace recipe, direct MCPB download links, clearer
  support routing, and a simulator-neutral interoperability evidence form.

Changed

• Upgraded the Model Context Protocol SDK from 1.29.0 to 1.30.0 and pinned
  @hono/node-server 2.0.12. The SDK now accepts the patched Hono 2.x line, so
  the npm artifact installs its shrinkwrapped production dependencies normally
  instead of embedding the SDK dependency tree.
• Tightened package budgets and now report both tarball and installed-tree
  footprint, cold and warm initialization, dependency-node count, and
  deterministic installed-package doctor results.
• Corrected native-Windows Claude Code setup to resolve npm's npx.cmd
  launcher through cmd, while retaining direct npx launch instructions for
  macOS and Linux.
• Clarified throughout the public documentation that CRUMB support is static
  saved-artifact analysis and that Logisim behavioral evidence comes only from
  bounded one-shot subprocess calls to a separately supplied official JAR.

Security

• Declared non-destructive behavior explicitly for every Logisim runtime tool
  while retaining readOnlyHint: false because Logisim may update local Java
  preferences.
• Added privacy and support disclosures to the installable npm package and
  MCPB, and kept both packages free of proprietary simulator binaries, private
  fixtures, source screenshots, credentials, and broad filesystem roots.
