WHICH THREADED FEATURE OF THE PART A `thread_size` DESIGNATION BELONGS TO - the male stud, the female socket, the suction port or the pressure port. A QUALIFIER AND NOT A FLAT PROPERTY, because a part with two threads publishes two designations and a loose role token could not say which belonged to which. THE PART PUBLISHES BOTH AND THE TRADE PRINTS THEM AS TWO FIELDS: Lemforder's tie rod end 33927 01 carries `External Thread: M12x1,5` AND `Internal Thread: M16x1,5`; febi's 11988 carries an internal `M14 x 2`; Bosch's every motorsport pump sheet carries `Mech. connector intake side M18x1.5` AND `Mech. connector pressure side M12x1.5`; Delphi's HFP923 carries `Inlet Fitting Thread Size: M12 - 1.5` AND `Outlet Fitting Thread Size: M12 - 1.5`. A BARE `M12x1.5` ON SUCH A PART IS NOT A WEAK STATEMENT BUT A WRONG ONE HALF THE TIME, which is `mix_ratio_basis`'s argument [b157] on a second shape. THE VALUES ARE ANATOMICAL PLACES, NOT TWO CROSSED FACETS [A5]: each names a feature of the part - the E-9 amendment's own atom, a registered typed place - and its gender follows from the feature rather than being asked again. The gap that remains is recorded rather than hidden: a two-ended coupling rod publishes TWO EXTERNAL threads (Meyle 30-16 060 0000/HD prints `Thread Size 1` and `Thread Size 2`; febi 33492 prints `M12 x 1,5` and `M10 x 1,5` as two unindexed rows) and this qualifier cannot yet tell end one from end two, and Delphi publishes a separate `Inlet Gender: Female` field this does not hold. Concern measurement.

Which thread is answered with one word chosen from the thread roles list — the same word shared across every product that uses it.

It is a qualifier of thread size — it has meaning only inside a thread size statement, never on its own. It belongs with thread size to measurement — its measurable, physical facts.

It is answered inside every thread size statement, not as a standalone question on a kind.

answered with: ◇token — a token — a word chosen from a fixed vocabulary, shared and filterable across products.
value domain: Thread roles — the vocabulary its answers are drawn from.
qualifier of: thread size — required_one per statement — it has meaning only inside that host's statement.

Answered inside every thread size statement — not a standalone slot on any kind.
