The single results form compares a whole number exactly (a count). The construction and inspect
cases gave positions and volumes as whole numbers, which the form they were written for compared
within tolerance; they are decimals now. The NPT groove fix makes ladder 06/023 pass: its golden
entry is the passing run (51 faces, 8226.4042 mm3).

The shared core (crates/smlib, the grader, doc eval.rs, engine features.rs and the kernel's core)
is in PATHS-ALL; the new areas' copies of it are dropped, so an area reruns on its own files and the
core reruns them all. sheet-metal also watches the sheet commands, the sheet document and the DXF
writer. 116 commands a case now uses leave EXEMPT; 25 geometry commands are still to cover.

Two branches added a results field in different forms ({step, json} and {command, pointer,
value}). The grader keeps one: a 1-based step, an optional JSON pointer into its answer, and the
value matched as files are, with an optional relative or absolute tolerance. The construction and
inspect cases are rewritten to it.

167/168: every new case passes against its hand answer but 06/023 (1/2-14 NPT external), whose
groove stops 0.015 mm past the crest at its section's middle, under the crest cone on the section's
deeper side, so a sliver of each tooth's flank stays (0.94 mm3, 1.1e-4). The 139 cases before keep
their statuses and counts; their volumes and areas re-measure within 2e-6 on this SMLib.

Base flange; an edge flange at 90 deg; four made together, the corners closed on the mitre plane
with the rule's gap, at 90, 72 (leaning out, the ends run on along a slant) and 108 deg (leaning
in, cut back); round, rectangular and tear reliefs; a hem; a fold, unfolded and refolded; the
tray's flat pattern (outline size and area, bend lines); a bracket with a hole and a flange on a
flange. K = 0.5, so every volume is T x the flat area. The 108 deg tray is a sheet-metal rig case too.

From the script's last sheet.flat_pattern result: the outline's size, its area less the
cut-outs', and the bend lines, each matched to its own one of the result's either way round.

G 1/2 external and Rp 1/2 internal (ISO 228-1 / ISO 7-1, 55 deg) by Pappus turn by turn; R 1/2
and 1/2-14 NPT external and Rc 1/2 internal tapers (1 in 16 from the standard's diameter at the
free end, crests cut by the major or minor cone) by the screw sweep's Jacobian, integrated exactly
(ladder_lib.sweep_removed); an S20x4 run down to a shoulder with its steep flank toward the end and
toward the start, which moves where the groove stops; tip: start, and a Tr20x4 chamfered at its own
30 deg and 2.5 mm; refusals for a Tr chamfer without a depth and for the square form.

1/4-20 UNC (#7, 0.201 in) and Rc 1/2 (17.6) through the stock, 1/4-28 UNF (5.45) blind with a
flat floor, 1/4-18 NPT (10.85) through: a cosmetic thread in a straight hole, so each volume is
the stock less that cylinder. The drills are the catalogue's (Guhring, Yamawa YEU23); each method
gives the standard's minor diameter beside it.

A Default row, a 60 mm row, a row without the hole, a height column and rules
that suppress the hole or drive the height, each checked after activation;
preview leaves the design; refusals for a row that cannot build, unknown rows,
columns and features, and a rule a row breaks.

Suppress a hole and the block is whole again; a round moved before the notch
runs the whole edge and is cut by it; deleting a sketch takes its cut and
deleting the block leaves the round and cut failing; roll to the middle gives
the part at that step; edits, compute all and folders, each with a refusal.
The new history area has its KNOWN_FAILING (every case passes) and PATHS.

A case's construction field names construction points, axes and planes with the point, line or
plane each must be, and results reads values out of the commands' own replies by JSON pointer.
