Per-namespace memory lifecycle policy (COG-1).

Controls type-specific TTLs, decay curves, and spaced repetition behaviour. All fields have sensible defaults; only override what you need.

Used by [DakeraClient::get_memory_policy] and [DakeraClient::set_memory_policy].

Fields

working_ttl_seconds: Option<u64>

Default TTL for working memories in seconds (default: 14 400 = 4 h).

episodic_ttl_seconds: Option<u64>

Default TTL for episodic memories in seconds (default: 2 592 000 = 30 d).

semantic_ttl_seconds: Option<u64>

Default TTL for semantic memories in seconds (default: 31 536 000 = 365 d).

procedural_ttl_seconds: Option<u64>

Default TTL for procedural memories in seconds (default: 63 072 000 = 730 d).

working_decay: Option<String>

Decay strategy for working memories (default: "exponential").

episodic_decay: Option<String>

Decay strategy for episodic memories (default: "power_law").

semantic_decay: Option<String>

Decay strategy for semantic memories (default: "logarithmic").

procedural_decay: Option<String>

Decay strategy for procedural memories (default: "flat" — no decay).

spaced_repetition_factor: Option<f64>

TTL extension multiplier per recall hit (default: 1.0; set to 0.0 to disable). Extension = access_count × sr_factor × sr_base_interval_seconds.

spaced_repetition_base_interval_seconds: Option<u64>

Base interval in seconds for spaced repetition TTL extension (default: 86 400 = 1 d).
