test: require complete typecheck fixture coverage

docs/CURRENT_STATUS.md

@@ -56,6 +56,7 @@ Ready now:
 - 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, 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, field-to-field, compound arithmetic field expressions, and arithmetic/text expression result types, direct `CHECK TYPE` metadata acceptance for NUMBER/TEXT/YESNO fields, 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, numeric and text results from simple arithmetic/text expressions in object-field assignments, plus a plain beginner-facing unknown-field diagnostic when the assigned expression type is not inferable yet
 
 Still needed:
+- Keep the focused typecheck validator's fixture list complete as new positive and negative examples are added.
 - richer typed function signatures and return values
 - type checking through branches and loops
 - richer object field type checking beyond simple direct assignments

 3a. Keep package diagnostics actionable: invalid package manifest format fields now name the file and explain how to repair it, separately from an absent manifest. Keep package validation honest by checking that the project manifest has one non-empty project name, that the project and each listed package manifest declare the exact supported manifest version, package version, local source, and expected package name, and that lockfiles declare exactly one current release version.
 3b. Keep package security validation in Forgejo/Gitea CI so unsafe names, exact manifest-version/name/version/checksum mismatches, missing manifests, duplicate project manifest versions and packages, duplicate lock packages, duplicate package manifest names, versions, and checksums, and lockfile errors remain release blockers.
 4. Add small examples for each foundation feature before adding bigger syntax. The object-field foundation now includes positive and negative validation for field expressions such as `SET player.score player.name`, `SET player.score player.score + 1`, `SET player.name player.score + 1`, explicitly typed field assignments, simple and chained aliases such as `SET alias player`, `SET backup alias`, followed by `SET backup.score ...` or `CHECK TYPE backup.score IS ...`, chained aliases in object-method calls through both `DO` and compatibility `CALL ... WITH`, and arithmetic/text expression mismatches; typed containers also accept a map with nested type metadata when it is added to a `LIST OF MAP`; broader alias/control-flow checking remains planned.
+5. Keep the focused typecheck validator complete: every `typecheck_*.claro` fixture, including positive fixtures, must be exercised by release validation.
