typecheck: reject extra class field tokens

docs/CURRENT_STATUS.md

@@ -57,7 +57,7 @@ Ready now:
 - a narrow function/method argument check: `CHECK TYPE parameter IS TYPE` inside a function or simple object method lets `claro typecheck` accept correct checked calls, catch mismatched `DO`, `CALL ... WITH`, `DO object.method ...`, and compatibility `CALL object.method WITH ...` arguments, including checked methods that appear after another method in the same class, report missing checked function and method arguments, report missing unchecked arguments for simple functions and simple object methods in both modern `DO` and compatibility `CALL ... WITH` forms, treat empty compatibility calls such as `CALL greet WITH` and `CALL player.rename WITH` as missing-argument mistakes, catch extra arguments to simple functions and checked methods even when the checked method appears after another method in the same class, catch modern `DO` and compatibility `CALL ... WITH` calls to undeclared simple functions, explain when `DO object.method ...` or compatibility `CALL object.method ...` happens before the object is created with `NEW` even if the method name is also wrong, and catch modern plus compatibility calls to undeclared object methods with a class-specific `TEACH` hint
 - function and method declarations now reject repeated parameter names with a direct repair hint before calls are checked, including modern and compatibility `TAKES` / `LEARNED` functions and methods; object methods with the same name are also rejected within a class with a rename hint in both modern and compatibility method syntax
 - class declarations now reject repeated field names within the same class with a direct repair hint before field types are used, so two `HAS score ...` lines cannot silently choose conflicting metadata; different classes may independently use the same field name
-- class field declarations now reject missing types such as `HAS score` and unknown types such as `HAS score BANANA` with the field name, class name, supported type examples, and a repair hint before object-field checks use the metadata
+- class field declarations now reject missing types such as `HAS score`, unknown types such as `HAS score BANANA`, and extra tokens such as `HAS score NUMBER TEXT` with the field name, class name, supported type examples, and a repair hint before object-field checks use that metadata
 - class declarations now reject repeated class names with a direct repair hint, so two `CLASS Player` blocks cannot silently compete for the same name
 - object creation now rejects repeated object names with a direct repair hint, so two `NEW Player player` statements cannot silently replace one another during type checking; when a script declares at least one class, a misspelled `NEW` class name gets a direct declaration hint without changing the older permissive no-class form
 - a narrow object-field assignment/check-type check for simple `NEW Class object` plus direct `SET object.field value` and `CHECK TYPE object.field IS TYPE` cases when the class declares `HAS field TYPE`; validation now covers correct NUMBER, TEXT, and YESNO direct assignments, explicitly typed field assignments, explicitly typed method-body assignments to undeclared fields with a `HAS field TYPE` repair hint in modern and compatibility method syntax, dedicated positive NUMBER/TEXT/YESNO `CHECK TYPE` metadata fixtures, simple and chained object aliases for both field assignments and `CHECK TYPE` metadata (including a chained TEXT-field check), aliased object-method calls including chained aliases in modern `DO` and compatibility `CALL ... WITH` forms (with a dedicated positive modern `DO` chained-alias fixture), field-to-field, compound arithmetic field expressions, and arithmetic/text expression result types, negative NUMBER/TEXT/YESNO field `CHECK TYPE` metadata mismatches, NUMBER/TEXT/YESNO-expectation unknown-field `CHECK TYPE` diagnostics, missing-object field assignment and `CHECK TYPE` diagnostics, NUMBER/TEXT/YESNO wrong-type diagnostics, field collection when a `HAS` field appears after a simple method, NUMBER/TEXT/YESNO-valued unknown-field diagnostics for direct assignments to undeclared fields including explicitly typed assignments, numeric and text results from simple arithmetic/text expressions in object-field assignments, plus method-body field assignment and `CHECK TYPE` diagnostics for NUMBER, TEXT, and YESNO fields in modern and compatibility syntax, including compatibility YESNO `CHECK TYPE` metadata coverage, direct method assignments to undeclared fields now produce a beginner-facing missing-field diagnostic when the assigned expression has a known type, and a plain beginner-facing unknown-field diagnostic when the assigned expression is not inferable yet in both modern and compatibility method syntax; method-body `CHECK TYPE` now reports an undeclared bare field with the expected type as a repair hint in both modern and compatibility method syntax, including compatibility `TAKES` / ...; explicitly typed assignments to declared method fields now validate the class-declared field type instead of trusting only the inline type annotation, so a wrong value such as `SET score TEXT "oops"` reports the method and field in the diagnostic
