 # Changelog
 
+## v1.18.26-dev object field unknown TEXT diagnostic validation
+
+- Added a focused negative `claro typecheck` fixture for direct object-field assignment to an undeclared field with a TEXT value: `NEW Player player` followed by `SET player.nickname "Ace"` when the class only declares `HAS score NUMBER`.
+- Wired the TEXT-valued unknown-field fixture into both the typecheck diagnostics validator and `claro validate`; no production typechecker change was needed because the existing narrow direct object-field diagnostic already reported the learner-friendly message.

 ## v1.18.26-dev object field unknown-field diagnostic
 
 - Added a focused negative `claro typecheck` fixture for direct object-field assignment to an undeclared field: `NEW Player player` followed by `SET player.level 3` when the class only declares `HAS score NUMBER`.

-Both sides of this narrow field foundation are covered by validation: `tests/typecheck_object_field_good.claro` checks that `SET player.score 10` is accepted for a `HAS score NUMBER` field, `tests/typecheck_object_field_text_good.claro` checks that `SET player.name "Ada"` is accepted for a `HAS name TEXT` field, `tests/typecheck_object_field_yesno_good.claro` checks that `SET player.ready YES` is accepted for a `HAS ready YESNO` field, `tests/typecheck_object_field_bad.claro` checks the NUMBER wrong-type diagnostic, `tests/typecheck_object_field_text_bad.claro` checks the TEXT wrong-type diagnostic, `tests/typecheck_object_field_yesno_bad.claro` checks the YESNO wrong-type diagnostic, and `tests/typecheck_object_field_unknown_bad.claro` checks the unknown-field diagnostic.

 This slice is intentionally small: it covers direct `NEW Class object` plus `SET object.field value` cases in one file. Broader object flows, aliases, method return checks, and richer object signatures remain future work.
