Returns the existing default namespace if one exists, or creates a new one using the universal template. This is the primary onboarding entry point — Studio calls this on first upload to ensure a namespace exists without requiring the user to choose a template. The default namespace supports all file types (video, image, audio, PDF, text) with pre-configured extractors and a universal retriever. If the request carries an `X-Namespace` header that resolves to an existing writable org namespace (e.g. one just created via the wizard), the scaffold is provisioned into THAT namespace instead of creating a "default" one. ## OpenAPI ````yaml post /v1/templates/scaffolds/default openapi: 3.1.0 info: title: Mixpeek API description: >- This is the Mixpeek API, providing access to various endpoints for data processing and retrieval. termsOfService: https://mixpeek.com/terms contact: name: Mixpeek Support url: https://mixpeek.com/contact email: info@mixpeek.com version: '0.82' servers: - url: https://api.mixpeek.com description: Production security: - BearerAuth: [] paths: /v1/templates/scaffolds/default: post: tags: - Scaffold Templates summary: Get Or Create Default Namespace description: >- Get or create the default universal namespace.
