Every document in the library carries a living assessment: whether it is currently owned, versioned and verified against reality. 46 of 48 are living. The two that are not, and why:
StaleMemory ConstitutionCONST-MEM
Not currently a living document: last touched 2026-06-19, predates the unified memory architecture and the P0 memory-backend workstream. It describes a memory model that no longer matches the running system. It should be re-baselined against the canonical memory service before it can govern again. This is a debt item, not a dead document: the constitution's intent (memory is written, owned and forgotten with discipline) is still law, but its implementation details are stale.
SupersededHandshake PDR v2PDR-H-v2
Replaced on 2026-08-15 by HANDSHAKE_PDR.md. Retained in the registry for provenance so the lineage is visible; it is not a governing document anymore.
Assessment is per-document in registry.json, refreshed on every build. A document is living when it is owned, versioned, sha256-pinned and updated when the world changes. The registry itself is a living document: it states its own status, its own sha256, and the evidence that it reflects the canonical sources.
