What's live in Memory this week

First note in what will become a weekly cadence. Short on prose, long on signal.

Live today

Five verbs — save(), search(), bridge(), list(), inspect(). The whole SDK fits in your head. The first save() at a path defines the schema; subsequent saves are validated against it.
MCP server — read and write from any client that speaks Model Context Protocol. Confirmed working in Claude Desktop, Cursor, Claude Code, and Crew AI.
Hybrid search — 60% similarity weighed against 40% recency. Stale decisions fade. Decisions superseded by newer ones drop in rank automatically.
Multi-tenant by design — each tenant’s data lives in its own surface. Never blended, never used for training. Export the whole graph anytime.
Bridges — depends_on, supersedes, part_of, conflicts_with, implements. Typed relations between paths, first-class.

A derives_from bridge type — for tracking provenance when a memory is generated from another (summary, distillation, translation).
Inspector improvements — Mermaid diagrams now group by subtree depth instead of flat connectivity. Easier to read at scale.
A sample MCP riligar.bridge.list({ from: ... }) call surfaced in the inspector tooltip.

Open source vs. closed. Still pending. Will be locked in writing on the Architecture document before we ship any client code.
Pricing. Free tier definition is locked. Pro tier $19/mo is proposed; needs sign-off before signup goes live.

That’s it. The next note lands Tuesday.
