Every dimension the house is generated from is below, with its class and its citation. This is the project’s honesty layer, and it is given a room of its own because a smooth 3D render implies a precision the sources do not have.

Which of these matters most

Nearly every dimension on this page is the author’s own. What the provenance bar does not say is whether that matters. Each row below is computed by rebuilding the house: one dimension is pushed 20%, and the house is measured to see how far it follows. Nothing is estimated — the figures are the difference between two runs of the generator.

1. 1carryLength0.88 mmargin against what can be carried
2. 2shoulderWidth0.37 mwidth of the floor
3. 3lyingLength0.34 mdepth of the floor
4. 4frontHeight0.33 mheight of the high edge
5. 5floorMargin0.14 mdepth of the floor
6. 6floorHeight0.08 mheight of the high edge
7. 7sleepGap0.07 mwidth of the floor
8. 8ridgeSection0.03 mthe longest member

If only one dimension could be surveyed, this is the one. This is sensitivity, not uncertainty: it shows what moves, not how likely the value is to be wrong. The 20% is itself the author’s choice.

Invariants

There is no measured drawing yet, so correctness rests on structural truth. These checks fail the build.

• pass
  Bilateral symmetry about Symmetric about z = 0, across the row of sleepers — and deliberately not so along the fall of the roof

  120 points; largest mirror deviation 0.00 mm.

• pass
  Every tenon contained in its mortise

  3 pasak, takik and tumpu joints; every one engaged.

• pass
  No joint spans more than one stage

  Every joint engages two parts from the same stage or from consecutive ones.

• pass
  Stage ordering, and nothing below ground

  15 parts, every one bearing on something already standing or on the ground.

• pass
  Mesh integrity: indices, triangles, normals

  0 triangles; indices in range, none degenerate, every normal unit length.

• pass
  The floor is a row of sleeping bodies, and they fit

  4 people lying side by side need 2.20 m, and the floor is 2.90 m × 2.42 m. Four other packs here measure a human body and all four measure a height; this one measures a width.

• pass
  Nothing in it is longer than a person can carry

  The longest member is 3.04 m against the 4.40 m that can be cut nearby and carried by hand. The woloan house is bounded by the length of a lorry and the Baduy imah by a pole that may not be spliced; this one by what a person can pick up — and that bound comes closer every time one more person has to sleep under it.

• pass
  Nothing is pegged, nailed or buried

  3 joints and every one a rattan lashing; zero buried posts; 3 materials and all of them were standing in that forest an hour before the building was. A shelter that has to be left on the day somebody dies cannot hold anything anybody would come back for.

• pass
  Every part declares the dimensions it came from

  15 parts, every one tagged. By least-sourced input: 0 measured, 0 canon, 15 interpolated.

• skipped
  Checked against a measured drawing of a real house

  Skipped. No measured drawing has been wired in, so there is nothing to compare against. This check will not be made to pass by weakening it.

What a check is preventing

Ten green rows are not a reason to believe anything. So one check is run against a house built to break it, and what is printed below is that check’s own verdict rather than a description of it.

Giving everybody a little more room to sleep is not an indulgence; it is the first thing a family of six would change. And no part of the building becomes wrong: it still stands, the roof still falls one way, the floor still holds everybody, nothing is pegged or buried, and it still goes up in an afternoon. What breaks is the edge pole across the front — it is now longer than anything that can be cut nearby and carried by hand, so the shelter that would be better to sleep in is a shelter that cannot be built where it is needed.

The second house is never rendered. It is built during the build, failed, and thrown away.

This bar moves as real surveys are wired in. That movement is the project's progress metric.
