Provenance

The data and the steps to check that every token comes from the measured pool and was assigned by the rule committed before the mint.

Measurement

3 jobs on IBM Heron r2 processors, run before the mint opened.

Backend	Circuit	Shots	IBM job ID
ibm_marrakesh	uniform	1,408	dag1nk1hvn6c73cq0h3g
ibm_fez	uniform	512	dag1nj8mhr3c73e4hskg
ibm_marrakesh	bell	156	dag1npfi3e6s738lqf6g

The pool hash is the SHA-256 over the ordered raw registers: uniform circuits first, ibm_marrakesh then ibm_fez, then the Bell circuit; each job's shots in the order the hardware returned them.

Trait code

SHA-256 of the files that turn measured bits into traits, recorded before any hardware job was submitted. The same values are in PROVENANCE.md in the source archive.

Hardware statistics

Bias of the uniform jobs. Min-entropy is summed over the 156 qubits; the worst qubit is the one furthest from p(1) = 0.5.

Backend	Shots	mean p(1)	min-entropy	Worst qubit
ibm_marrakesh	1,408	0.5057	145.9 / 156	q82 at 0.0582
ibm_fez	512	0.5012	147.1 / 156	q72 at 0.6230

How to verify

Code and pool. Download the source archive and check its SHA-256. Unpack it and run python verify.py; it needs only the Python standard library. It checks the trait code against the hashes in PROVENANCE.md, recomputes the pool hash from the three measurement files, and re-renders all 2,048 registers, comparing each SVG with svg-sha256.json.
Commitment. The pool hash and the salt hash are the pool_sha256 and salt_sha256 attributes of the collection account, written when the collection was created, before the mint opened.
One token. Its metadata carries pool_position and svg_sha256. Run python verify.py --position N with that position; the computed hash must equal svg_sha256.
Assignment. The SHA-256 of the published salt must equal salt_sha256. With chain/binding.mjs from the source archive and Node.js, derivePermutation(salt, 2048)[N] is the pool position of the token whose mint index is N (Heron Collapse #0007 has N = 7), and must equal its pool_position. The salt file also lists all 2,048 positions.

Not verifiable. That the measurement came from IBM hardware. IBM jobs are visible only to the account that ran them; the hashes prove the pool was not altered after it was committed and that every artwork follows from it, not where the randomness came from.
