Move a deck's lots in bulk mode from its removal refusal page #302

Outcome. A collector whose deck can't be removed because its zones still hold copies opens those lots in bulk mode with one button, as they already can for a place.

• Depends on Deck zones in every location picker and in the collection filter #252 (the collection filter's "Deck (all zones)" value, deck:<id>).
• Spec 059 added "Move them in bulk mode" to a place's removal refusal page (Locations::SelectionsController). Spec 062 (decisions 5 and 7) left it off a deck's refusal page until the filter knew zones, and spec 065 (Deck zones in every location picker and in the collection filter #252) leaves it out on purpose to keep that change to pickers and the filter.
• The button opens the collection in bulk mode, filtered to the deck (all zones), with every lot of the deck selected, as spec 059 does for a place. The collector then uses Move to… or Remove.
• Works without scripting. Another account's deck is a 404, as on the refusal page.

A follow-up from spec 065's review (2026-11-10), filed by the maintainer's ruling. It is refined into a spec when its turn comes, and checked then against the north star's rules.
