New ADRs: next number, same three-section format (Context, Decision, Consequences). An ADR is amended by a new ADR that supersedes it, not by rewriting history; superseded decisions stay visible as the path taken.
ADR-0001 opens a 3.6-4.0 arc designed around statifier's six upstream seams. The remaining decisions from that design - the Context struct, typed undefined, and the statement layer - get their ADRs as their releases are taken up, not in advance.
