Suggest four times from the host's own free space

[JamesmarkeyUK]

With a calendar connected, the create screen can now fill the poll in itself. Beside the week view, "Suggest 4 times" reads the host's free/busy and proposes four candidate slots — weekdays only, between 10:00 and 16:00 in the poll's timezone, and at most one morning and one afternoon on any given day, so four options can't all be one Tuesday. They're ordinary slots once added: drag to move, click to remove, click the button again for four more.

How it picks

suggestFreeSlots in src/lib/autoSlots.ts is a pure function fed the same per-day busy segments the week grid shades from, so a suggestion lands exactly where the shading says the host is free.

• Spread beats density — one option per day first, alternating which half of the day it tries so the set isn't four identical 10am slots; it doubles up on a day only once the weekdays run out.
• Afternoons prefer 13:00 onwards, dropping into the 12:00–13:00 hour only when nothing later fits.
• Starts snap to the same 30-minute grid a drawn slot uses; the first day is cut off an hour ahead of now; slots the poll already has count as busy, so a second click adds four more options rather than four duplicates. Slot length copies whatever the host is already proposing (an hour by default).

Wiring

CreatePoll.suggestTimes fetches the whole 21-day scan range itself rather than trusting whichever weeks the grid happens to have loaded, and aborts if any connected provider's read fails — half a diary would propose times the host isn't actually free for. The grid then jumps to the week the first suggestion landed in (new focus prop on CalendarWeekView), since slots off-screen look like nothing happened.

hostCalendar's private zonedParts moves into time.ts as zonedDayAndMinute, so "now" and the busy segments are read in one frame; calendarWeekday joins it for the Mon–Fri test.

Testing

• npm test — 77 passed, 13 of them new: the 10–4 window, the weekend skip, the one-morning-one-afternoon rule, the lunch-hour fallback, existing-slot avoidance, partial results when the diary is full, and a timezone-frame test that fails if the busy data is read in UTC instead of the poll's zone.
• npm run typecheck and npm run build both clean.
• Not exercised against a live provider — that needs Supabase credentials and a connected Google/Microsoft account.
