refactor(codegraph): make the code graph a fully native engine (no external tool)#94
Merged
Conversation
…rnal tool) Replace the external-MCP wrapper with a zero-dependency TypeScript code-graph engine: scan a project, extract symbols + imports per language (regex, 12 languages), resolve intra-project import edges, count cross-file references, and answer architecture / search / schema queries in-process. Verified on enigma's own src (173 files, 2421 symbols, 606 import edges). - Expose it through enigma's own MCP server (enigma_codegraph_index/projects/ search/architecture), gated by codeGraph; fold codeGraph into mcpEnabled(). - Revert the second-managed-server generalization in mcp-deploy.ts (unused now). - Dashboard: real sliding switch (data-kind=bool, not a text button), an "Index a project" action, native rendering; the toggle now hits enigma's own backend so the previous "Could not reach the server" is gone. - CLI: enigma codegraph <status|on|off|index|projects|arch|search>. - Rewrite tests for the native engine; update docs + CLAUDE.md. No external binary, npx, or third-party package - and no upstream project name.

Follow-up to #91. That PR shipped codebase memory as a wrapper around an external MCP; this replaces it with a fully native, zero-dependency engine, as requested - no external binary, no npx, no third-party package, and no upstream project name anywhere.
