 - `__dot_init` — the bootstrap logic, inlined in the same file rather than

+`__dot_help`'s glob over `~/.config/dot/commands/*.fish` is duplicated in
+`~/.config/fish/completions/dot.fish`'s `__dot_custom_subcommands` rather than

-dot status

-Any git subcommand works — `dot` forwards whatever you type straight to git.

-## Adding new subcommands
-
-Beyond `init`, `dot` looks for `~/.config/dot/commands/<name>.fish`. Each file
-should define a `_dot_<name>` function; `dot <name> args...` sources the file
-and calls it. These files are deliberately *not* under
-`~/.config/fish/functions/`, so they never become independently invokable
-commands or clutter tab-completion outside of `dot` itself.
-
-`~/.config/fish/completions/dot.fish` discovers them automatically by
-scanning that directory, so a new command file gets tab-completion for free.
