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

Common runtime errors

Unsupported function names, invalid required arguments, invalid lookup ranges, division by zero, negative SQRT input and failed FIND searches can produce formula errors.

02

Recompute model

Formula output is recalculated when cell state changes. For larger workloads, the product includes a worker-based recompute path to reduce main-thread UI blocking.

03

Debugging order

Check the leading =, function spelling, separators, A1 references, range boundaries and supported function list before assuming a sync problem.
