computed column "{colId}" read undeclared dependency "{field}". Add it to `value.deps` or the value will go stale.

What happened

The dependency proxy caught a computed column reading a field it did not declare. The value is computed correctly *this* time; the problem is invalidation - when that field changes, the grid does not know this column depends on it, so the cell keeps its old value and the grid shows a number that is quietly out of date.

The fix

Add the named field to value.deps.

The smallest fix

value: { deps: ['gross', 'tax', 'rate'], get: (p) => … }
