• File cli/repo_submanifests_test.go — part of check-in [5377023003] at 2026-10-18 17:04:24 on branch feat/submanifest-reader — feat: select over the main-branch tip, and add submanifests status

  Repo.EnableSubmanifests(k) now analyzes the current trunk, the check-in the next commit most plausibly descends from, instead of the newest check-in; with no trunk check-in only an explicit k succeeds. A test puts a newer one-file check-in on another branch to show which one is read. Repo.DisableSubmanifests returns only an error and documents that existing trees stay.

  `libfossil repo submanifests status` prints the three settings and whether the repository holds a tree; `retune` requires --k, and `disable` prints zit's note when trees exist. The SDK pages are rebuilt with make docs-gen-sdk. (user: [email protected], size: 3982) [annotate] [blame] [check-ins using]
