Return the normative weather constraints for construction work types. Call this first when you need to know the temperature, wind, humidity or precipitation limits that apply to a work type, or to enumerate all work types in a category. Provide either a single work_code or a category, never both. Returns an empty list with matched_count=0 when the category contains no work types; this is a successful result, not an error.

Evaluate whether one construction work type may proceed during one specific day of weather. Returns a verdict of allowed, conditional or prohibited together with the exact constraints that were breached and by how much. Use this to check a single work-day; use plan_work_schedule when you need to place several works across a forecast. The verdict is computed by deterministic rules, not estimated — treat it as authoritative.

Estimate how long a concrete or coating work type needs to cure under a given sequence of daily temperatures, using the Nurse-Saul maturity method. Use this when a work type has a curing stage and cold weather may extend it beyond the nominal duration. Returns the ready date, or capped=true when the supplied temperature sequence is too short to reach the required maturity. Fails with no_curing_stage for work types that have no curing stage at all.

Produce a feasible day-by-day schedule for several construction works across a weather forecast, honouring declared dependencies between works. Each work is placed in the earliest window where no day is prohibited. Returns both the scheduled works and the works that could not be placed, each with an explicit reason. Use this instead of repeated validate_work_window calls when planning more than one work.
