A host can share its score sheet and others nearby can join it, found the
same way games are, or by typed address over a hotspot.
- A joining guest is not let in on its own say-so. The host is prompted with
the guest's name and answers Allow or Deny. A device already let in that
drops out (locked phone) is let straight back; the host can remove anyone.
- The host's sheet is authoritative. What travels is what was done (SheetOp:
add round, rename, move column, ...), not whole sheets, so changes made at
the same moment all land. A guest's own changes show at once and are laid
over the host's sheet until confirmed (SheetReplica).
- Sync asks the host for the sheet as it stands, and runs on its own when
the app returns to the front, as it does for a game table.
- Hello carries a purpose and hosts advertise one, so a game join screen does
not list score sheets and a game guest typing a sheet's address is told so.
- The Scorekeeper screen now expresses every edit as a SheetOp, so one grid
serves a local sheet, a hosted one and a joined one.
