XLVIII.18 records 2026-11-11: the LFS trim (Captain Bob: "they can be
trimmed out"), version.h untracked and BLOCK_MAP.md without its timestamp
(#145), my put-back error and its fix, the acceptance rulings (never in the
background; all logs and CSVs are evidence), the acceptance of 9415d7ed,
and alpha.4's Gitea release marked final.
README: alpha.4's release is no longer a pre-release.
