Enum CompiledCostExpr 

pub enum CompiledCostExpr {
    Unknown,
    Expr(CostNode),
}

A compiled cost-expression AST (FKC §4.4 / §2.3 strategy A).

Cloneable + comparable so it can ride on a resolved record and be asserted in tests. Held as data, never as a fn-pointer (this slice).

Variants

Unknown

Sentinel: no cost claim (absent block / class-only / judge_measured with no expressions). Maps to unknown_cost in the register slice.

Expr(CostNode)

A parsed expression tree.
