Confirm (validate) nested-message behavior is already covered; no code change required

[Copilot]

This issue asked whether (validate) = true still generates nested message validation calls, specifically for enclosed message fields. Current implementation already performs nested validate(...) invocation, and test coverage already exercises this path across singular, repeated, map, and Any-wrapped messages.

• What was verified

  • (validate) generation for message fields invokes nested validation rather than relying on callers to manually validate nested targets.
  • No regression was found in current generator/runtime behavior.

• Existing coverage that addresses the issue

  • tests/validating/.../ValidateITest.kt — singular/repeated/map + Any nested validation cases.
  • tests/consumer/.../ValidateRuleITest.kt — consumer-level (validate) rule behavior for enclosed messages.
  • tests/runtime/.../EnclosedMessageValidationSpec.kt — runtime enclosed-message validation semantics.

• Code path confirmed

  • java/.../option/ValidateGenerator.kt already emits nested validation calls:

if (unpacked instanceof ValidatableMessage validatable) {
    validatable.validate(fieldPath, typeName)
        .map(ValidationError::getConstraintViolationList)
        .ifPresent(violations::addAll);
}

No source or test modifications were necessary in this PR.
