What it does

01 · Persistent memory

A durable KV store with audit logging

Facts, preferences, and conventions stored in a durable backend with a 200-row rolling audit log. Every write answers who, when, and why.

survives restarts

02 · Three-layer scoping

Global, project, and user scope

Global memories cross every project. Project memories are per-repo and auto-detected. User memories follow your profile across repos. No bleed, no loss.

auto-detected

03 · BM25 retrieval

CJK-aware, dependency-free Okapi BM25

Latin word tokens plus CJK unigrams and bigrams. Pinned entries surface ahead of equal-relevance matches. Evaluated in CI against a fixed golden set — success@5 = 100%, MRR = 0.902.

measured, not vibes

04 · Human-confirmed writes

Models suggest; humans promote

A background distillation pass extracts durable facts from explicit remember-intent, corrections, and verified failure streaks — but models only write suggested entries. Human confirmation makes them effective.

Development activity

How often does this project move? Judge from the repo itself. This panel reads the project's real history the moment you open the page — the latest commits on main, plus per-day commit counts and line churn across the whole project.
