Struct OpticalForgettingConfig 

pub struct OpticalForgettingConfig {
    pub enabled: bool,
    pub compress_provider: ProviderName,
    pub compress_after_turns: u32,
    pub summarize_after_turns: u32,
    pub sweep_interval_secs: u64,
    pub sweep_batch_size: usize,
}

ScrapMem optical forgetting configuration.

Controls progressive content-fidelity decay: Full → Compressed → SummaryOnly. The sweep is orthogonal to SleepGate (which decays importance scores); optical forgetting compresses content in place based on age.

Example (TOML)

[memory.optical_forgetting]
enabled = false
compress_provider = ""
compress_after_turns = 100
summarize_after_turns = 500
sweep_interval_secs = 3600
sweep_batch_size = 50

Fields

enabled: bool

Enable optical forgetting sweep. Default: false.

compress_provider: ProviderName

Provider name from [[llm.providers]] for LLM-based content compression. Falls back to the primary provider when empty.

compress_after_turns: u32

Number of conversation turns after which Full messages are compressed. Default: 100.

summarize_after_turns: u32

Number of conversation turns after which Compressed messages become SummaryOnly. Default: 500.

sweep_interval_secs: u64

How often the sweep runs, in seconds. Default: 3600.

sweep_batch_size: usize

Maximum messages to compress per sweep iteration. Default: 50.
