Six operations. Explicit success or refusal.

Recipe Calculus evaluates admitted recipes and bundles. Results are non-publishable evaluation artifacts tied to exact input identity and effective selection.

Operation	Purpose
`resolve_selection`	Return the deterministic active recipe and component-instance view.
`resolve_formula`	Resolve one active ratio or percentage formula to ordered quantities.
`scale`	Apply one exact factor, or derive it from one root formula target.
`convert_quantity`	Perform exact supported UCUM same-dimension or temperature conversion.
`reading_order`	Topologically order selected active steps with authored tie order.
`schedule`	Calculate earliest starts from explicit dependencies and durations.

Numeric discipline

Internal work uses exact rational arithmetic. Public decimals are independently quantized half-to-even with at most four fractional digits. Schemami never redistributes rounding residuals to make displayed line items add up cosmetically.

Scheduling is not a calendar

schedule is an earliest-start projection. “Na véspera” remains authored section language; date, timezone, reminders, and operational placement belong to an application.
