OOI — The Chords Experiment (oxexp-chords, CHX-A1..A8)

OOI oxexp-chords — The Chords Experiment (the third sibling): 56 rows — THE CHORD, the resolved readout of a DECLARED SPAN of notes read as ONE object (span + member notes in address order + census multiset + schedule signature), existing only after every member note resolves; the seven vectors (I + C1..C6) and the witnessed attempt ledger. All three received records consumed ONLY through their published surfaces. Every read sealed BEFORE it runs; verdicts landed as-is; no claim about physical complex systems, natural emergence, or collective phenomena, ever; no claim about artificial learning systems, ever; no claim about human knowledge, groups, or society, ever; no claim about physical quantum mechanics or any physical measurement problem, ever; no claim about consciousness or phenomenal experience, ever; no claim about physical cosmology or astronomy, ever; NO claim on any Millennium Prize problem, ever.
