Built against something real.

Four projects, each answerable to something outside itself: SI constants, the maritime collision rules, database constraints, the filesystem.

Selected work

Two have case studies. The other two link to their source.

Currently building

VelaScan

Not shipped, and not yet written up. There is nothing to link to, which is the honest state of it; when there is, it will appear above with the others.

About

Everything here has to agree with something outside itself. That is a narrower constraint than it sounds: a simulation can be wrong in a way no test catches unless the test knows what the real answer is, so the projects favour the cases where a constant, a published rule or a database can hold the code to account.

The same constraint decides how they are built. Lodestar recomputes known quantities through the same code paths the simulations use; Vela Sea keeps its simulation layer free of the drawing layer so the whole game can be played by a bot with no window open. Both are the same idea: make the thing checkable, then check it.
