Scarcity

Two numbers define a card's scarcity: the gates it burned, and the cap its drawing was given. Neither is editable.

Rarity is not assigned. It is the number of gates that actually burned.

When a drawing reaches its cap, the registry refuses the next claim. The drawing stays public, and a copy can still be taped out, but no further numbers will exist.

How numbers are issued

Numbers are assigned in claim order. In the normal flow the page claims immediately after tapeout, so earlier buyers receive lower numbers. Three consequences follow:

What an edition number means

6 / 100 means this was the sixth ADD4 to complete the claim step. It does not mean the sixth card ever taped out — only the sixth to be stamped. The registry keeps that record permanently, and the number travels with the circuit across any number of sales.

Three numbers, three meanings

NumberScopeExample
Circuit idGlobal on the processor#7 — the seventh card taped out here
EditionWithin its drawing6 / 100 — the sixth ADD4
TFD token idGlobal on the wrapper#7 — the seventh card wrapped

They drift apart because the wrapper is one contract serving every drawing. That is the usual NFT convention: the token id is global, the edition is a trait.
