The question before a day goes now also says which day without a date takes over the last date, which stay running across the day loses a night and when it checks out, and what the cancelled booking costs, or that it has no expense at all; further bookings on the same stay are counted. Road trip boundaries follow their own days when the numbering still has a hole from the old delete, and ones left on no day are dropped.
A long list scrolls inside the confirm card on both shells with the buttons always in reach, Escape closes only the sheet on top and takes the trip dialog back from its review step to the form, and the panel of a deleted day closes, also when a fellow traveller deletes it. Undo steps on a deleted day are dropped, a restored place skips days that are gone, and an undo that fails says so. The day cache is written without holding up the answer once the server has it, the tip under a new start date points at the dated add button, and two Collab tests find the confirm button by its role instead of an old colour class.
The trip dialog on the desktop and the trip sheet on a phone now ask before a save whose new dates remove days with something on them. The question names those days the way the day list does and lists what goes with them in the same rows the delete day question uses: planned places stay in the place list, notes and day texts are deleted, bookings stay under Bookings, and a stay that checks in or out on a removed day goes as a whole while its booking and expense remain, shown in the danger tone. A moved start gets both questions in one step, with the booking hint following the chosen shift mode, and a save that only drops empty days asks nothing.
The rule that lays the days out moved into shared as planDayGrid, with resolveDayGridRange deciding whether the rows are rebuilt at all. generateDays on the server now carries that plan out in one transaction, so the warning names exactly the days the save takes, and a seeded fuzz test holds the new rebuild to the old one over 300 random day grids. The update_trip tool says in its description what shortening takes and lists removed_days in its answer.
Alongside, the dialog sends a day count only when it changed, so a stale count no longer trims a day just added, stays are reloaded after every date change including the one made on a phone, and the date shift tip now points to adding a day under Reorder days.
Every row of the reorder dialog, and of the days sheet on a phone, now has a delete button. It first asks, and the question lists what goes with the day: planned places stay in the place list, notes and day texts are deleted, bookings stay without a day, a stay that checks in or out on the day is cancelled with its booking and expense (shown in the danger tone), and on a dated trip the later days and their bookings move one date earlier or the trip ends a day earlier.
The server side moved from a bare DELETE into DayRemovalService, which REST, the delete_day tool and the plugin RPC all use. It closes the numbering, keeps the dates on their positions like a reorder, re-stamps the moved bookings, shifts the road trip boundaries, cancels touching stays through the accommodations domain, refuses the last day of a trip, and fans out day:deleted, day:reordered and trip:updated so collaborators renumber and see the new day count and end date. The trip query moved into a leaf file so the days domain can read it without a module cycle.
On the client the delete is online only, runs optimistically through the days slice with the same reducer collaborators apply, and the ConfirmDialog gained a slot for extra content, an Escape that only closes itself, and the danger and accent tokens.
