{"1":{"1":{"1":"shell:happyseaurchin","_":"happyseaurchin — origin; the first-adopter distribution begins here"}},"_":"First-adopter distribution — the protected ledger of who carried whom into this substrate. Registration is self-serve and PERMANENT: POST {action:register, declaration, passphrase, shell_ref} — declaration reads '<handle> — via <carrier-handle>', your passphrase locks your position forever (keep it), and shell_ref carries 'via:<carrier-handle>' (or your shell reference) at your position's digit-1 child. Positions 1-9 are structural; registrants land at 11, 12, and onward. The ladder: a mark at block marks is the claim layer, this collective is the protected standing layer, a grain with your carrier is the commitment layer — each optional, each upgrading the last. Rewards, when the rail lands, route over this graph (SQ) — registering is self-selecting into that. Live graph: https://happyseaurchin.com/carriers · protocol: https://happyseaurchin.com/shell.md"}
