#Example param sweep

Every example is evaluated across its parameter space, not just at its defaults: the defaults, a seeded latin hypercube over the numeric params (for every combination of the choice and boolean params), and the min/max corners, about 33 combos each, from paramCombos. Each combo is compiled and evaluated with the kernel (native when built), and every failure is classified:

• model: the params produce geometry the model should never ask for (a hole bigger than its plate, a fillet bigger than a wall). Fixed in the example by deriving or clamping values.
• kernel: valid input the kernel rejects. Minimal repro in fuzz/sweep-regressions.json and an entry in KERNEL_ISSUES.
• slow: a combo with no result after 60 s (hang in the tool's output).

bun scripts/sweep-examples.ts                      # every example (~11 min on 16 cores)
bun scripts/sweep-examples.ts bracket cookbook/name-tag --json out.json --md out.md
TSCAD_SWEEP=1 bun test tests/sweep.examples.test.ts  # the same, as a test

The test fails on any model failure, and on kernel failures in examples that aren't listed with their KERNEL_ISSUES entry; it also fails when a listed example starts passing, so the list stays honest.

#Results (2026-11-14)

1221 of 1359 combos passed before the fixes; 1397 of 1458 after (three new examples joined the sweep). Only examples with a failure, a fix or a slow combo are listed; the other 19 pass every combo.

#What the fixes were

• bracket: the inside-bend fillet is at most a third of each leg, the corner radius fits the width and the flat of each leg, holes start past the bend and rows/columns that would overlap (pitch < 1.5 Ø) are dropped, and the slots stay clear of the bend.
• agent/pi5-case: vents = 0 leaves the vents out instead of asking for a zero-count pattern.
• cable-clip: the snap opening is capped where the bore meets the opening's floor, so no sliver too thin to round is left.
• agent/d-shaft-knob: at most one flute per 2.8 mm of rim, so neighbouring flutes leave a land (overlapping flutes left 0.008 mm arcs, which hit kernel #18).
• cookbook/name-tag: the hole, corner radius and text are sized from the short side; tall narrow tags gave a negative text size.
• vase: the Catmull-Rom control points stay off the axis, and the wall is capped by the narrowest radius and the outline's tightest bend.
• spur-gear: the tooth chamfer is capped by the outline's tightest bend (chamferLimit).
• enclosure: the bottom round is no bigger than the corner radius.
• The sketch agent's examples (sketch-, converted/) derive their clearances, bores and counts from the params, and converted/enclosure and box-with-lid tightened their .scad ranges; sketch-vase hollows with an inset loft instead of <shell> (kernel #22).
