libtmux::is_pane_id

is_pane_id ( value : std::string_view ) → bool function [source] ¶ function [source] ¶ is_pane_id: Whether a value is written as an id, which is what decides that it needs no separator validation below — not whether tmux would resolve it.

x is an id by this test and no pane by tmux's, and both are right: it carries no separator, so composing it can only produce the caller's own mistake back.
