Expand description

What one dotted path did across one key’s window.

Fields§

§seen: u64

Document samples in which the path was present.

§first_at_s: f64

Window-relative seconds of first / last presence.

§last_at_s: f64§last_seen_sample: u64

The key’s document-sample index at last presence — what “absent since” is measured against.

§kinds: BTreeMap<&'static str, u64>

JSON kind → occurrences (type stability: one entry is stable).

§changes: u64

Times the value differed from the previous observation of this path.

§last_change_at_s: Option<f64>

Window-relative seconds of the last change; None = never changed.

§num_min: Option<f64>

Numeric min/max/last, when the path carried numbers.

§num_max: Option<f64>§num_last: Option<f64>§distinct: BTreeSet<String>

Small-domain distinct values (canonical JSON), until the domain overflows DISTINCT_CAP.

§distinct_overflow: bool

The domain outgrew the cap (or carried values too large to track) — the set above is then cleared, not silently partial.
