Unreleased​

Changed​

  • The README meets the stranger it now has. Install from crates.io as the front door, the synthetic eval as the try-it-with-no-data path, wiring blocks for mecha (unprefixed, marked untrusted — the interlock reasoning stated), Claude Code, and any MCP client, and the privacy story gathered into one section: encrypted at rest, stream-first ingestion, the sensitivity ladder, true delete, local by construction.
  • The self-improvement plan is a design document. ./self-improvement now states the three doctrine decisions (autonomy by exception, graph-first with session-splitting, the mechanical error contract), the five gossip roles, the mechanism catalog with build waves, and every settled design point with its rationale — in an impersonal voice.

0.1.0 - 2026-08-16​

The first public release: a clean-room extraction of a private research repository. History starts here on purpose — the development record was a journal of the data the project exists to hold, and no filter makes a journal safe.

Added​

  • Three crates: mecha-graph-core (ingest, enrich, resolve and link, retrieve — knows nothing about any agent), mecha-graph (the CLI), and mecha-graph-mcp (a stdio MCP server any client can sit on), published to crates.io.
  • Eleven MCP tools: kg_search, kg_entity, kg_timeline, kg_related, kg_upsert, the verification family (kg_verify, kg_pending, kg_verdict), and a small task family. The tools carry their own kg_ namespace, so harnesses that support unprefixed registration can drop the server prefix.
  • A synthetic eval world: eval/synthetic/run.sh builds a throwaway graph from a fictional corpus (a twelve-message mailbox, a small calendar) and grades 24 retrieval queries — no personal data, no live store, works on a fresh clone.
  • Encrypted-at-rest store at ~/.mecha-graph/graph.db (SQLCipher; the raw key beside it, mode 0600), MECHA_GRAPH_* environment overrides, stream-first ingestion, capture_delete retention for file sources, a four-level sensitivity ladder with private-by-default retrieval exclusion, and true delete (redact purges an episode and everything derived from it).
