Struct BudgetCell 

pub struct BudgetCell {
    pub declared: Option<i64>,
    pub observed: usize,
    pub origins: usize,
    pub worst_origin: Option<String>,
    pub worst_observed: usize,
    pub exempt: Option<String>,
    pub over: bool,
    pub examples: Vec<String>,
}

One {var} row’s declared-vs-observed key population (#221).

Judged per origin: RFC 04 §1’s table bounds cardinality per producer, so one origin over the bound is conclusive and several origins’ healthy populations are never summed into a fake violation. over is the only verdict this cell carries — observed under declared is not one (a bounded window proves a lower bound, never the population, RFC 09 §5.1 O6), and a {path...} family is exempt and says so rather than passing (the RFC 08 §6.1 v1.20 shape).

Fields

declared: Option<i64>

The declared bound, when the subject declares one.

observed: usize

Distinct concrete keys observed across all origins over the window.

origins: usize

Origins that expanded this family.

worst_origin: Option<String>

The origin with the most expansions — the one the bound judges.

worst_observed: usize

That origin’s distinct-key count (0 = family unobserved).

exempt: Option<String>

Some("rest-variable"): a {path...} family, unbounded by construction — exempt, and saying so.

over: bool

The worst origin exceeds the declared bound — the finding.

examples: Vec<String>

Example expansions from the worst origin (capped).
