通过 toolkit 的共享 IR，将 C# source parser 连接到 C# generator。
当前表现较好的部分
Parser 能力：shape-ir
Generator 能力：shape-ir
IR 流程：shape
当前限制
C# support is limited to single-file records, property-based classes, and symbolic enums.
Attributes, inheritance, interfaces, generic declarations, methods, and other full-language constructs remain unsupported.
Enum serializer metadata and non-name wire values are not preserved; collection and numeric representation behavior follows the C# adapter boundary.

Enum serializer metadata and non-name wire values are not preserved; collection and numeric representation behavior follows the C# adapter boundary.
Go support is limited to single-file serializable data-model declarations rather than the full Go language.
Imports, cross-file resolution, functions, methods, interfaces, generics, and embedded-field promotion remain unsupported.
Go aliases are rejected because the shared IR preserves named types but not alias identity.
Pointers are interpreted as nullable values and omitempty as optional field presence.
Fixed-size arrays are widened to variable-length arrays with semantic loss.
Constraint annotations are not emitted as Go runtime validation and are reported as semantic loss.

Enum serializer metadata and non-name wire values are not preserved; collection and numeric representation behavior follows the C# adapter boundary.
Java support is limited to single-file records, restricted structural classes, and unit-only enums rather than the full Java language.
Exactly one public root record, class, or unit-only enum is required; additional declarations are package-private definitions.
Structural classes contain only instance fields; interfaces, generic declarations, wildcards, annotations, data-carrying enums, JavaBeans, and non-string Map keys remain unsupported.
Reference types are conservatively interpreted as nullable because Java declarations do not establish non-nullability.

C# support is limited to single-file records, property-based classes, and symbolic enums.
Attributes, inheritance, interfaces, generic declarations, methods, and other full-language constructs remain unsupported.
Enum serializer metadata and non-name wire values are not preserved; collection and numeric representation behavior follows the C# adapter boundary.
JSON Schema support is limited to the current IR-aligned Draft 2020-12 subset.
Validation-heavy and document-system features such as external references remain unsupported.
Object-only allOf can be merged; references, non-object compositions, not, and conditional schemas remain outside the current JSON Schema parser subset.

Enum serializer metadata and non-name wire values are not preserved; collection and numeric representation behavior follows the C# adapter boundary.
Kotlin support is limited to data classes, unit-only enums, and schema-facing List, Map<String, T>, and Set containers.
User-defined generics, ordinary class parsing, mutable or concrete collection implementations, defaults, annotations, inheritance, and sealed hierarchies remain unsupported.
Set is represented as an array with a unique-items constraint and may be generated as List when that constraint is unavailable.

C# support is limited to single-file records, property-based classes, and symbolic enums.
Attributes, inheritance, interfaces, generic declarations, methods, and other full-language constructs remain unsupported.
Enum serializer metadata and non-name wire values are not preserved; collection and numeric representation behavior follows the C# adapter boundary.
OpenAPI support is currently limited to extracting schemas from components.schemas rather than processing the full API document.
OpenAPI generation emits only a canonical 3.1 schema document and does not recreate source metadata or API operations.
Paths, operations, request and response bodies, parameters, headers, security, callbacks, and webhooks are outside the current parser boundary.
Only local references to components.schemas are supported; external and URL-based references are unsupported.
Object-only allOf compositions can be merged into shared IR; conflicting or non-object compositions remain unsupported.

Python support is limited to modern dataclass type annotations and does not execute Python.
Defaults, field(...), inheritance, user-defined generics, quoted forward references, and serialization behavior remain unsupported.
String-keyed dict[str, T] fields and restricted map aliases are supported; typing.Dict and non-string keys remain unsupported.
Constraint IR is not rendered as runtime validation; unsupported constraints are reported as semantic loss.
