function ConvertTo-OpenApiDocumentModel { <# .SYNOPSIS Turns a raw document tree (any supported version) into the normalised document model. Never throws for document problems. .DESCRIPTION Detects the version (OA001 when unsupported: the model then has no operations), converts Swagger 2.0 to the OpenAPI 3 shape, then normalises servers, security schemes, the default security, every component schema (first, in document order, so they are cached) and every operation. Missing operationIds are generated (OA010); duplicates (compared case-insensitively, as the generated module keys operations in a hashtable) get a '_2', '_3'... suffix (OA011).
