Concepts

Three memory tiers

• short_term: fresh session facts, highest recency weight.
• episodic: consolidated session-level events and decisions.
• semantic: stable long-lived knowledge.

Lifecycle promotion

EidolonDB can promote memory over time:

• short_term -> episodic when access/importance signals increase.
• episodic -> semantic via distillation.
• old low-signal memories can decay or be archived.

This keeps recall useful without manual pruning.

Hybrid retrieval

Queries combine:

• semantic similarity (vector score)
• recency
• importance

The result is better context quality than plain vector search alone.
