openapi3-ts 4.6.1 oas31.js isSchemaObject spreadSchema source
💡 Result:
<search_synthesis>
For openapi3-ts 4.6.1, the requested code is in the published bundle at https://unpkg.com/openapi3-ts@4.6.1/dist/oas31.js (the package listing confirms that oas31.js and its source map are shipped artifacts) [1]. The corresponding TypeScript source is src/model/openapi31.ts, and the repository’s current source shows the implementation of isSchemaObject as: ts export function isSchemaObject( schema: SchemaObject | ReferenceObject, ): schema is SchemaObject { return !Object.prototype.hasOwnProperty.call(schema, &`#39`;$ref&`#39`;); } In other words, it classifies a value as a schema object when the object itself does not have an own $ref property; a Reference Object is identified by an own $ref. The generated declaration for version 4.6.1 exports the same type guard [2], while the source implementation and its purpose are visible in the upstream model source [3]. I found no spreadSchema symbol in the openapi3-ts 4.6.1 oas31.js/oas31.mjs artifacts or in the corresponding OAS 3.1 model source. The bundle is primarily a re-export wrapper around the model/DSL modules; the relevant 3.1 runtime helper is isSchemaObject, not spreadSchema [4][1]. If spreadSchema appears in a stack trace or searched snippet, it likely belongs to another package/version, a bundler-generated helper, or application code rather than openapi3-ts 4.6.1 itself. The package’s documented import paths are import { oas31 } from 'openapi3-ts' or the direct subpath openapi3-ts/oas31 [5][6]. Also note that the 4.6.x changelog records the change allowing $ref in OpenAPI 3.1 Schema Objects, which explains why the runtime guard distinguishes objects by presence of $ref [7].

$ref の sibling キーワードを参照解決時に保持してください。
openapi3-ts@4.6.1 の openapi3-ts/oas31 の isSchemaObject は、own $ref を持つオブジェクトに対して false を返します。spreadSchema はその結果、$ref の参照先だけを再帰的に返し、元の enum や type などを破棄します。
validateRequestBody はこの spreadSchema を通過します。例えば、参照先が { type: "string" } で、元のスキーマが $ref と enum: ["ok"] を持つ場合、"bad" が enum 検証を受けずに受理されます。
$ref を含むスキーマでは、参照先を解決した後に $ref 以外の sibling キーワードを OAS 3.1 の適用ルールに従って合成してください。このケースのリクエスト検証テストも追加してください。

現状は $ref とそのほかのキーワードを一緒に使っているものはないのでいったんこのままとしたいです

@kamekyame 承知しました。現状は $ref とほかのキーワードを併用していないため、このPRでは変更を見送る方針で問題ありません。
将来の併用に備えて、対応を追跡するIssueを作成しますか？

OAS 3.1 の $ref と兄弟キーワードを allOf で適用してください。
spreadSchema は $ref の参照先だけを返すため、兄弟キーワードを破棄します。OAS 3.1 では、参照先と兄弟キーワードを両方適用する必要があります。
浅いマージも使用しないでください。例えば、参照先に required: ["id"] があり、兄弟 Schema Object に required: ["name"] がある場合、両方のフィールドを要求します。浅いマージでは一方の required が上書きされます。
validate は allOf の各要素を個別に検証するため、兄弟キーワードを $ref から分離して allOf に配置してください。
