vault — CLI for Ryan's R/J/F/I Obsidian vault.

Clobber-safe. Dry-run by default; pass --execute to act.
Operates on BOTH trees (/vault map + /data territory) and the topology manifest.

Subcommands:
  vault tree [SYS]              print topology (optionally one system)
  vault search <query>          find IDs/notes by code, title, or content
  vault show <ID>               show an ID's note + its /data home + blob count
  vault create <ID> "<title>"   create ID note (folder+folder-note) in /vault AND /data
  vault move <oldID> <newID>    renumber: rename note+folder, rewrite backlinks, move /data dir
  vault rename <ID> "<title>"   retitle in place, rewrite backlinks
  vault sync-data               reconcile /data skeleton to match manifest (create missing dirs)
  vault manifest                regenerate the topology manifest note
  vault report [--pretty]       deterministic Librarian report (delegates to vault-librarian.py)
  vault analyze [--sonnet|--opus] [-m MODEL] [--provider PROVIDER]
                                spawn a Hermes Librarian pass. DEFAULT: Haiku/Bedrock
                                (cheap+fast — the nightly/weekly tier). --sonnet / --opus
                                step up intelligence & cost for harder judgment calls.
                                -m/--provider override entirely (future/non-Bedrock models).
