- `README.md`, `docs/REPOSTRUCTURE.md`, `internal/cli/snapshot.go`: a
backup needs only write permission on S3; an rclone remote that can
move objects also needs read and delete, and an upload there stops
when its look-up is refused.
- `docs/DATAMODEL.md`, `docs/REPOSTRUCTURE.md`: a restore reads no
file, chunk or blob rows from the local index, but it does open it.
- `README.md`: confirmation prompts go to stdout.
- `internal/cli/remote.go`: `remote nuke` leaves the backup destination
store empty, not a bucket prefix.
- `README.md`: a TODO section, as `REPO_POLICIES.md` requires.
