Persistent memory + optional signed audit for AI coding agents.
world-model-mcp ships a local SQLite knowledge graph your agent queries every turn: hallucinations become verifiable, corrections stick across sessions, and regressions get caught before they land. Flip on the audit chain and every event is signed with FIPS 205 hybrid Ed25519 + SLH-DSA, verifiable offline forever. MIT-licensed, runs entirely local, works with 10+ AI coding agents including Claude Code, Cursor, Codex, Continue, Cline, Windsurf, GitHub Copilot Chat, pi, OpenClaw, and Hermes Agent.
Latest: v0.15.8. Docs-only refresh. No code changes. Adds a "Which one is right for me?" guide in the README to help a first-time reader decide whether the local
world-model-mcpserver is enough or whether they also want the hosted etch.systems companion for signed audit evidence. Every code path shipped in v0.15.7 continues to work identically. Full version history inCHANGELOG.md.

Head-to-head positioning against eight named peers on the audit / signing / anchoring dimensions the agent-memory space is converging on. Every world-model-mcp cell carries a provenance flag: own = measured / observed in the shipped product; cited = pulled from the competitor's own public landing, repo, or press.
Source of truth for this table lives in the hosted service repo: world-model-mcp-hosted/src/etch/competitor_matrix.py. Update in both places if you change either.
