09 · Data

Every curve, with its provenance attached

Every figure in this dossier carries one of six labels and a source key. There are 93 of them, and the split below is counted from the data modules at build time — so this page cannot claim a discipline the site is not actually keeping.

01

The six labels

39
Measured

Read off the bench with an instrument. The strongest thing we can say.

23
Implemented

Built and running, but not yet characterised. It works; we have not put a number on how well.

6
Calculated

Derived from measured inputs by a stated formula. As good as its inputs and its arithmetic.

9
Modelled

Produced by the model with no hardware in the loop. Defensible, and not evidence.

5
Reference

From a cited external source — published physics, or the design requirement itself.

11
Target

Planned. Does not exist yet, and is never written in the present tense.

02

What that adds up to

62 of 93 labelled figures are measured or implemented — things that exist on a bench. The rest are calculated, modelled, referenced or targeted, and are marked as such wherever they appear. That ratio is not flattering, and publishing it is the point: a number's label travels with it, so nobody has to guess which kind they are reading.

The build enforces this. scripts/verify.mjs fails on a figure with no status or no source, on a source key that does not resolve in the registry, and on the turbidity sweep disagreeing with the table published in the project README. None of it depends on anyone remembering.

03

Sources behind it

5 registered sources back every labelled figure. The full list, with what each one is responsible for, is on the sources page.
