Worked on the payloadcms/payload repository to deliver SDK and REST API parity for soft delete functionality, specifically enabling queries to include trashed documents. Implemented a trash option in SDK queries by propagating a trash parameter through request URLs and extending SDK utilities to support an optional trash flag in operation arguments. Serialized this flag in buildSearchParams.ts to align with existing patterns such as draft. Developed integration tests using TypeScript to verify that the trash parameter is correctly included in requests for various query methods. Focused on API integration, SDK development, and testing to ensure accurate handling of trashed documents.
