The manifest selects page ranges from source PDFs in output order, adds an outline and optional continuous Bates numbering, and splits the result into volumes. Each volume becomes a new vault object. Source bookmarks, form fields and page labels are not carried over. Outputs are not indexed automatically. Completion is reported through vault.assembly webhooks. ## OpenAPI ````yaml /openapi.json post /vault/{id}/assemblies openapi: 3.1.0 info: title: Case.dev API description: >- The AI-native platform for legal technology.
