Checks 1–7

Ebru is a 500-year-old Ottoman marbling craft — and, unusually for an art form, exact mathematics. So this computes it rather than imitating it: send any word, address or hash and get an original marbled sheet back as PNG or SVG. Ask again next year and it returns byte for byte identical, at any size. Seven traditional patterns, eight palettes ground from the pigments used at the bath.

A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.

outside the census

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
