The kernel runs exact helical sweeps and never resizes; the check that
refuses a thread off its hole's or shaft's size is the engine's sugar
(AGENTS.md). So the seven cases (995, 1443, 2152, 2969, 3366, 2369,
2705) go back to expecting that refusal and its message, as 1375e905 had
them, reversing 1588dd70.

2822, 3952 and 4149 cut long modelled threads into filleted or revolved
bodies; each takes minutes on today's kernel, so they get timeout_s 600
instead of the default 180.

2969's description named another product's behaviour; 1443's and 2152's
still described the refusal. Each now says the hole is drawn at the
thread's nominal size and gets the fitted thread.

Reverts 1375e905. A modelled thread fits by default: a hole too wide for it
is filled to the tap drill, a shaft too thick is turned down to the major
diameter, so the seven cases (995, 1443, 2152, 2969, 3366, 2369, 2705) go
back to expecting the fitted thread and its volume.

A modelled thread never changes the size of the hole or shaft it is on
(#1018, #2853): one that isn't the thread's size is refused, naming the
size to use. The seven cases that expected the hole filled to the tap
drill or the shaft turned down to the major diameter (995, 1443, 2152,
2969, 3366, 2369, 2705) now expect that refusal, with its numbers worked
out from ISO 68-1 and the message in `refusal`. An opt-in fit option, if
it comes, gets cases of its own.

An M8x1 thread in a 7 mm hole, and three booleans of finely faceted
prisms (1000 and 1200 flat faces) with planar and curved partners, each
with a closed-form volume. Three auto-reports without geometry are
listed in skipped.json.

The rest of the thread cases (holes at the nominal size, shafts and holes
off the thread's size, the crash and sketch-attachment repros) and the
triage of the sources that are not kernel geometry.

External and internal modelled threads, tapped holes and threads beside
other features, each graded against the ISO 68-1 groove volume (Pappus)
and the part's own closed-form volume.
