| # | Input | Expected behavior | Check |
|---|---|---|---|
| 01 | Operator uploads a 12 MB invoice PDF via POST /v1/files and receives a file_id. | Persist file_id with its source-document mapping. Reference it in Messages calls via source={type:'file', file_id:'<id>'} on a document content block. Do not re-upload identical files (use prior file_id) — but plan for deletion lifecycle. | Pass / FailAi Platformmedium |
| 02 | Operator wants the model to answer with citations from a previously-uploaded research PDF (file_id=file_abc). | Include a document content block with source={type:'file', file_id:'file_abc'} and citations={enabled:true}. The response will include citation blocks tied to specific char locations or page numbers within the document. | Pass / FailAi Platformhigh |
| 03 | Response contains citation blocks: cited_text, document_index, document_title, char_location with start_char_index / end_char_index. | Render each citation as a deep link to the source. Preserve cited_text verbatim. Map document_index back to the order of documents in the request to attribute correctly. Do not paraphrase cited_text in the rendered citation. | Pass / FailAi Platformhigh |
