Struct ObservationSummary 

pub struct ObservationSummary {
    pub window_s: f64,
    pub scopes: Vec<String>,
    pub samples: u64,
    pub keys_seen: usize,
    pub dropped: u64,
    pub synthetic_marked: u64,
    pub field_paths_dropped: u64,
    pub facts_evicted: u64,
}

What doctor --for observed (#161) — the scope statement that keeps its findings honest (O5: ** never crosses an @-chunk, so this section names exactly which selectors were watched), and the drop count that taints them (O6).

Fields

window_s: f64

scopes: Vec<String>

The selectors actually watched — coverage is a statement, not a vibe.

samples: u64

keys_seen: usize

dropped: u64

Samples the bounded observer missed; non-zero weakens every listen-phase finding and the report says so.

synthetic_marked: u64

Samples carrying the synthetic-traffic marker (RFC 09 §5.3, #162) — generated traffic judged as real would be a self-inflicted finding.

field_paths_dropped: u64

Field-intelligence paths (#223) the bounded per-path table refused to track — the O6 cost of that bound, absent when zero so pre-#223 consumers see an unchanged document.

facts_evicted: u64

Key projections the bounded facts cache (#107) retired during the window — non-zero means keys_seen, the budget sweep and the field context cover the retained keys only, and the report says what the bound cost (RFC 09 §5.1 O6). Absent when zero, so earlier JSON consumers see an unchanged document.
