Documentation rule: this VauSheet section describes the current implemented product behavior. It avoids claiming full Microsoft Excel parity or live-cursor collaboration where the current build does not provide it.
01

Realtime version signal

The client subscribes to UPDATE events for the current workbook metadata row. When a newer version number appears, VauSheet refreshes the latest workbook when safe to do so.

02

When local edits exist

If the current workbook differs from the synchronized base, VauSheet attempts to save/rebase rather than blindly replacing local changes with the remote document.

03

What this is not

Version 1.0.1 is not per-keystroke live coauthoring. There are no shared live cursors, presence indicators, CRDT/OT operation streams or guaranteed instant character-by-character fanout.
