A memory bridge,
not a database.
Composable, durable memory bridging cognition and production systems.
What Mnemo is
A memory bridge, not a database
Mnemo is the production-side face of the cognitive stack. It composes Stamen substrate dynamics with Heddle structured binding behind a durable interface, so systems that talk to it get a queryable, auditable, multi-tenant memory rather than a research demo. Compliance posture and audit streams are first-class endpoints, not retrofits.
Composition
One surface, two libraries.
Callers see one durable interface. Underneath, Mnemo keeps substrate dynamics and structured binding cleanly separated.
Mnemo
One durable interface. Queryable, auditable, multi-tenant.
Heddle
Structured binding, role-swap, multi-hop walk.
Bridge surfaces
How Mnemo is exposed
Mnemo is the place where cognitive memory becomes infrastructure other systems can depend on.
Composable memory
A single interface composes substrate dynamics from Stamen with structured binding from Heddle. Callers see one durable surface, not two libraries.
memory.bind / memory.walk
Compliance posture
A live posture endpoint reports what controls are active, what tenants are scoped, and what evidence has been captured. Compliance reviewers query this directly.
GET /compliance/posture
Audit stream
Every memory operation is observable as an audit event. A streaming endpoint exposes the trail in real time, ready to fan into governance systems.
SSE /audit/stream
One operation, end-to-end
From bind to audit, in one trace.
Every memory operation is observable. The audit event is part of the same trace, not a separate log to reconcile.

Multi-hop precision through the bridge
Retrieval through the durable interface matches the underlying memory library.
Where Mnemo lives
Production memory, where it matters
Long-lived agent memory
Agents that run for days or weeks keep their bindings, plans, and decisions in Mnemo. The memory survives process restarts and tenant boundaries.
Compliance-aware memory
Compliance teams query posture and audit streams directly. Memory becomes evidence.
Backing store for the cognitive stack
RL-X1 and RL-C1 read and write through Mnemo when running outside the research loop.
