// One-off (idempotent): seed the chipnet TLD-certificate beacon with the

// provider (so re-runs skip anything present), then mints a TREG for each
// missing TLD. Verifies at the end by rebuilding the snapshot from beacon
// history — the same code path the /tld-list.json endpoint uses.

// Extended 2026-08-29: asm, neo, gt, sc, sia, com; then dex, cex, nt; then dea.
// The operator holds the countersignature key that would otherwise gate
// ICANN-adjacent TLDs (.com, .sc, .gt, .neo) on mainnet; on chipnet no covenant
// enforces the gate, so these are seeded directly under operator authority.
// `.com` is HELD by the operator (excluded from the public registrar UI) so
// nobody else can claim names under it — the TLD cert stays on-chain, but no
// second-level registrations are offered. Future TUPD may set policy:"frozen"
// once the TLD covenant lands and enforces it.
