readCellField

Since v3.3.0

Read the raw stored value for field from row, honoring nested dotted paths — the non-accessor counterpart to resolveCellValue.

Resolution rules (back-compat critical, see grid-core.md DECIDED #438):

1. Plain field (no .) → direct row[field] (identical to legacy path), except prototype-polluting keys (__proto__/constructor/prototype) which return undefined — symmetric with writeCellField.
2. Dotted field whose literal key is an own property of row → that flat value wins (preserves synthetic-key rows that really store 'a.b').
3. Otherwise → nested traversal via getByPath.
