A field mutation targeting a declared field. Resolved values must satisfy
that field's shape, choices, validation, and assignment constraints.
field.setIfMissing supports nullable fields only. If a value exists, it
leaves the value unchanged and records no opApplied history event.
field.inc and field.dec require an initialized number field; their
delta defaults to 1. Both the delta and resulting value must be finite,
and the result must satisfy the field's validation bounds.
field.append adds one valid list member. field.updateWhere accepts only
array fields and merges an object into matching rows. The merge cannot
write _key or _type, and each resulting row must satisfy its declared
shape. field.removeWhere supports list fields. See Op for row
selection and history behavior.
