Expand description

Commit-certificate proof object for the parallel WAL data plane.

A commit becomes externally publishable only after the certificate is durably written. The certificate covers a contiguous commit-sequence range, the lanes that contributed to that range, and the pager-visible metadata that must be published once the ordered residue completes.
