Schedule grid & coach shifts

The schedule grid at /coach/schedule is a spreadsheet view spanning many events at once. Use it to:

Every coach gets a personal My shifts view at /coach/my-schedule showing only events they’ve been assigned to.

The grid layout

Left column — athletes (filtered by group), then below the divider, coaches.
Top row — events in chronological order, each labeled with day, time, type, and group(s). Tap the event header to jump to its edit page.
Cells in the athlete section — show the RSVP status:
- Y (green) — Yes
- ? (yellow) — Maybe
- N (red) — No
- — (gray) — No response
Athlete cells are read-only by design. To change an RSVP, open the event from the column header.
Cells in the coach section — show assignment status. Tap to toggle (admin only).

Bottom of athlete section — number of Yes RSVPs per event over the total athletes shown. Aldo’s planning rule: Maybe counts as no, only Y rolls into the headcount.
Bottom of coach section — count of assigned coaches per event.

Date range — defaults to the last 7 days through the next 28 days.
Calendars — pick one or more to combine. Common pattern: tick Ability + FIS together so you see those rosters side-by-side.
Groups — narrow further. If you skip this, you get every group in the selected calendars.
Filter selections are stored in the URL — bookmarkable, shareable.

When you assign:

The coach gets a phone push (if they have push enabled and haven’t opted out at /coach/settings → Phone notifications → Assignment changes).
The event shows up on their /coach/my-schedule view.
A chip on their /coach/today shows “Your shifts today & tomorrow”.

When you un-assign, they get a “shift removed” push (same opt-out applies).

/coach/my-schedule — full list of your assigned events for the next 4 weeks.
Chip on /coach/today — when you have a shift today or tomorrow, an orange chip appears at the top with a count and a link to the full list.
Phone push — fires the moment an admin adds or removes you (if enabled). Opens straight to /coach/my-schedule.

Set the From to a Sunday and To to four weekends out. That gives you a month-at-a-glance view.
Use the Ability + FIS calendar combo if you assign across both — athletes in both will only show once (their home group is the determinant).
Tap an event header to drop into edit mode without losing your grid scroll position.

No availability templates — coaches can’t declare “I’m always available Tue/Thu evenings” yet; admins assign event by event.
No coach attendance — the grid shows who’s assigned to cover an event but doesn’t track whether they actually showed up. (If we ever need that, we’d add a separate roster like for athletes.)
No notes on assignments — assignments are a binary “covering / not covering”. If you need to leave context (“Sarah covering for Bob”), use the event’s coach note or Telegram for now.
