The workshop

9 finished tools in 9 trades that have nothing to do with each other, and 466 checks holding them up. None of them was launched. They are here because what they show is not any one of the jobs they do.

What finished means here

Each one runs entirely in your browser, uploads nothing, keeps no account and holds no data. Each opens with a real job already in it, so what it does is visible before anything is typed. Each carries a test suite whose answers were worked by hand rather than read off the code, and each says in its own pages what it is not, because the limits are the part somebody needs before the features.

The number worth reading is not 9. It is that in one of these the test caught an error in the hand worked example rather than in the code. Anybody can claim to check their work. The part worth publishing is the check that found the author wrong.

All 9

cutplan

45 checks

An SVG into GRBL G-code for a laser, with the inside shapes cut before the outline that would drop the part.

loudmeter

36 checks

EBU R128 loudness on an audio file, and the single gain that hits the target without breaking the peak ceiling.

dotsheet

58 checks

Text into Unified English Braille, shipped with a back translator so the tables can be checked rather than trusted.

sheetwise

72 checks

A PDF imposed onto press sheets: saddle stitch, sewn signatures, n-up, cut and stack, step and repeat.

cutfill

45 checks

Earthwork cut and fill between existing ground and a proposed level, with the sections that let somebody check it by hand.

boardplan

37 checks

Parts onto boards in an order a panel saw can actually cut, rather than a nesting no operator could follow.

buildup

40 checks

A wall build up in, a U value out to ISO 6946, with the thermal bridging handled rather than ignored.

cuecheck

69 checks

A subtitle file against the reading speed and timing rules a broadcaster actually applies, cue by cue.

costcurve

64 checks

A marginal abatement cost curve that will not abate more of a stream than the stream actually emits.

Four of these stand behind a number somebody signs: a flooring take off, an earthwork quantity, a cutting list and a U value. None of them guarantees that number, and each says so on the result itself rather than only in the small print, because the person who signs it is the one who has to stand behind it.
