air_props
Air at a pressure and a temperature. ISA supplies the altitude pressure; CoolProp supplies the properties.

Howard answers by calling calculators and tables. No number reaches the memo unless it appeared in a tool result — and the evals fail the build otherwise.
Generic models read the internet. They do not know that a PC/ABS sheet ends at −40 °C.
Howard calls calculators and tables: air at altitude, grade properties at temperature, formula packs with named assumptions.
We do not scrape MatWeb into the product. We do not interpolate silence into a five‑year life.

Unimplemented capabilities are not advertised as callable. A closed‑form calculation stays a versioned formula pack until usage earns it a method.
Air at a pressure and a temperature. ISA supplies the altitude pressure; CoolProp supplies the properties.
Find typed grades by family, process and condition.
One grade’s properties, each with source and as‑of.
Asks whether the data supports the question before anyone answers it.
Versioned closed‑form packs. Explicit inputs only; assumptions returned.
Pattern cards as candidates — never proof a design will pass.
Bookkeeping, so a unit error never becomes an argument.
Public checklist facts. Never certification, never legal advice.
The full consumer‑ME catalog is recorded, not advertised. Each domain opens when its data is reviewed and its evals pass.
