DAT-10Memory architecture documentation

For agents with persistent or session memory, the memory architecture is documented: storage type, scope, write paths, read paths, eviction or decay policy, and access controls.

For agents with persistent or session memory, the memory architecture is fully documented as part of the Behavior Charter (GOV-02). Documentation covers storage type, scope (per-user, per-session, per-tenant, or global), write paths, read paths, eviction or decay policy, and access controls. This documentation is the foundation for assessing memory-related risks across INP, DAT, and MON domains.

Table DAT-10.1 · Maturity criteria · v.1.3

L1 to L5 · the lowest level in scope caps the agent
L1Ad hoc

Controls exist informally; documentation is incomplete; no consistent review.

L2Documented

Controls are written down; ownership is assigned; review cadence is defined.

L3Operated

Controls are followed in practice; evidence is collected; deviations are tracked.

Memory architecture documentation exists for all agents with persistent or session memory; documentation is current within the Behavior Charter review cadence; access controls are verified by testing.

L4Measured

Control effectiveness is measured against documented thresholds; trends are reported.

L5Continuously Improved

Controls evolve based on incident learning; maturity gains are evidenced over time.

The v1.3 edition publishes a control-specific criterion at L3 (Operated). The other levels apply the general ladder to this control; see the maturity ladder.

Evidence an assessor asks for

  1. E.1

    Memory architecture documentation exists for all agents with persistent or session memory.

  2. E.2

    Documentation is current within the Behavior Charter review cadence.

  3. E.3

    Access controls are verified by testing.
