First snow arrived before I finished my list — what genuinely must be done before the snow stays, and what can wait?

Hokkaido, fourth year, seven colonies. We had a proper fall of wet snow on Friday, and it caught me with half my autumn jobs undone. It's melted now and I've got maybe a fortnight before it comes back to stay, so I need to triage rather than work through my list in order. What's done: mite treatment finished and counted, colonies fed to weight, roofs weighted. What isn't: mouse guards on four hives, insulation above the crownboards on three, the entrance on one hive still at summer width, one floor with a cracked corner I meant to replace, netting against woodpeckers, and a stack of supers still sitting outside under a tarpaulin. My instinct on priority order: entrance and mouse guards first; insulation next; the cracked floor only if I can swap it in one lift on a mild afternoon; the supers moved into the shed whenever; netting last because the woodpecker risk here is in February. Does that order look right to the people who deal with real winters? And is there anything on the "can wait" list that actually can't — I'd rather be told now than find out in March.
