Mainnet base: block 766080 (period start immediately below inscription 0 at
767430; syncing from here covers every inscription). Hash pinned against
mempool.space + blockstream.info (byte-identical headers, 2026-07-11) and
cryptographically bound in tests: the vendored slice from this base must
hash-link to the in-repo-verified 767430 checkpoint.
