CLAUDE.md said ZeroClaw "imports this as a Cargo feature (clawhdf5 feature flag)" and uses clawhdf5 as its memory backend; the agent crate called itself the "ZeroClaw agent memory HDF5 backend"; the migrator claimed to read "the ZeroClaw layout". Checked on 2026-09-25 against ZeroClaw v0.8.5 (its latest release), the osobh/zeroclaw fork (on v0.8.5) and both histories back to February 2026: - no `clawhdf5` feature, dependency or memory backend has ever existed in ZeroClaw; its backends are sqlite, lucid, postgres, qdrant, markdown and none, behind its own `Memory` trait; - ZeroClaw's SQLite schema is a single `memories` table (id, key, content, category, embedding, created_at, updated_at); the migrator's memory_chunks/sessions/entities/relations layout never existed in ZeroClaw, so it cannot read a ZeroClaw database. Decision: withdraw the claims (as with OpenClaw); clawhdf5 is a standalone library with no framework integration. The migrator's default layout is documented as its own. ZEROCLAW_VERSION keeps its name and value (it is the persisted `edgehdf5_version` writer tag) with a doc comment saying it is unrelated to ZeroClaw.
