  Reaching for --force usually means something did not get pruned. It is one of these:

    Not idle yet          A commit or a source edit inside idle_days (15 by default).
                          This is the one --ignore-idle is for.
    Lockfile unusable     The package manager could not confirm it. Run the command
                          dev-prune printed, then try again. No flag skips this check.
    Opted out             `ignore.devprune.json` in the root, or `\"ignore\": true`
                          in `.devprune.json`.
    Under the size floor  Smaller than min_size_mb. `--min-size 0` includes it.
    Not registered        `devp link .` first; `devp status` shows what is tracked.
    Nested or symlinked   A submodule is pruned as itself, never as part of its
                          parent, and a linked directory is refused. By design.
    Too deep              Beyond scan_depth (6 levels). `devp config set scan_depth N`.

  `devp run --dry-run` names the actual reason, per repository.

  tree, including this list. It has read it. It wrote it.
