static/js/format.js (17). One function. Retires the formatTime hook: 12 -> 11. WHY A MODULE FOR ONE FUNCTION. formatTime was a host hook — loops.js and section-practice.js both reached back through the seam for it. It is ALSO, by pure accident of who calls it, inside the dependency closure of the library carve that comes next. Leaving it there would have made loops.js and section-practice.js import the LIBRARY in order to format a timestamp — nonsense, and a cycle waiting to happen. Same rule as the transport carve: a hook is a cycle you agreed to live with; an import is a dependency you actually have. formatTime has a real owner. It just isn't app.js, and it certainly isn't the library. Give it a home and both consumers import it directly. A leaf on purpose. Anything else that turns out to be a shared pure formatter belongs here too; nothing does yet (I checked — formatBadge, _safeImageUrl and _fetchJsonOrThrow have no callers outside the library), so nothing else is here. node 1040/1040, host contract 2/2, ESLint 0.
