The whole corpus, tethered. Every ROOT0 repo carries a .dlw seal; those seals are linked into one append-only SHA-256 hash-chain — link[i] = sha256(index|slug|seal|prev), a genesis derived from an anchor string, a head that commits to everything. This page ships the control arm client-side: a from-scratch SHA-256 recomputes it all, zero network, so you verify the provenance yourself — and can tamper any seal to watch it break.
The math is real and runs in front of you: genesis is recomputed from the anchor string (not asserted), and the head is recomputed by hash-chaining all 1458 seals — with a pure-JS SHA-256 that matches Python's hashlib byte-for-byte. Change any seal and the chain diverges from that link onward and the head stops matching — tamper-evident. Append-only: a new sphere adds one link at the tip; every earlier link is unchanged.
This attests the seals as inlined here, in this order. It does not independently prove each seal still matches its repo's live content — that check is the repo's own <slug>.dlw/.attribute (the seal commits to it) and its .chain tether. And a seal is an attribution/provenance marker, not a claim about the artifact's quality. The chain proves integrity and order, not merit.
