Enum MissingTimestampPolicy 

pub enum MissingTimestampPolicy {
    KeepBaseWeight,
    Drop,
}

What to do with an observation that has no observed_at_unix_seconds when BuildConfig::time_decay_half_life_days is set. Inert when time decay is disabled.

Variants

KeepBaseWeight

Score it at its un-decayed weight, as if it were current.

Drop

Exclude it entirely – treat “unknown age” as “untrustworthy” rather than “trustworthy”.
