Core family size per construct

A core is one syntactic realisation of a construct. The battery builds eight per construct and the bootstrap resamples them. The draft says the eight are "drawn from a family of at least 24"; this table is that family.

The family size is prod(len(levels[axis])) inside generate/core.py:spread() — the number of distinct cores the generator could build — read by intercepting spread, so the figure comes from the generator itself. Where a construct's cores split by subtype, spread is called once per pool; the minimum over pools is the construct's figure, since a draw comes from one pool.

Measured for 188 of the 188 built constructs. Minimum 42, median 210, maximum 1280. The claim holds: every measured family has at least 24 members.
