A single memory entry stored by an agent.

Fields

id: String

agent: String

content: String

category: String

tags: Vec<String>

created_at: DateTime<Utc>

last_accessed: DateTime<Utc>

access_count: u32

importance: u8

Importance score (1-10). Default: 5. Set by agent at store time.

memory_type: MemoryType

Classification of memory origin (episodic, semantic, reflection).

keywords: Vec<String>

LLM-generated keywords for improved retrieval.

summary: Option<String>

One-sentence summary providing context for the memory content.

strength: f64

Ebbinghaus strength score. Starts at 1.0, decays over time, reinforced on access. Entries with low strength may be pruned.

Memory::store preserves whatever value the caller supplies — no normalisation or clamping at insert time. Memory::recall reinforces the stored value by +0.2 per access (capped at 1.0) unless the caller opts out via MemoryQuery::reinforce = false. Decay is applied lazily at read time via effective_strength.

related_ids: Vec<String>

Bidirectional links to related memory entries.

source_ids: Vec<String>

IDs of source entries that were consolidated into this one.

embedding: Option<Vec<f32>>

Optional vector embedding for semantic search (hybrid retrieval).

confidentiality: Confidentiality

Access classification — controls which trust levels may read this entry.

author_user_id: Option<String>

User ID of the agent/user who authored this entry (multi-tenant authorship).

author_tenant_id: Option<String>

Tenant ID of the agent/user who authored this entry (multi-tenant authorship).
