• File internal/tag/tag_leaf_test.go — part of check-in [245a0ed306] at 2026-10-20 02:08:49 on branch feat/submanifest-reader — conformance: re-pin the three drafts to their -00 names

  zit check-in 68a3f76cb7 renames the artifact-format, repo-state and sync-protocol drafts from -01 to -00 in their headers, cross-references and reference entries, and retitles each Changes appendix "Changes in This Revision". No normative text changed and no section number moved.

  The pinned copies take zit's file names, the requirement tables pin the new hashes, and the comments, tests and docs that cited the -01 drafts cite the -00 ones. The refresh script copies every draft under its own name. The sparse-cone copy is re-pinned to d497c2432f, whose text is unchanged. Coverage counts are identical before and after.
