Get a short-lived link to the ORIGINAL DOCUMENT filed against something in the books — the receipt behind a posted expense, or the receipt/sales note/supplier bill/bank-in slip/name card riding a PENDING draft. Use it to CHECK a document is on file, or to re-read one you filed earlier. Find what to ask for first: search_expenses reports `hasAttachment` and an `attachments` list (with an `attachmentId`) on every posted expense it returns, and each create_*_draft / revise_draft result reports whether an original rides that draft. Give `owner` plus the `id` of the thing that owns it — for a posted expense that is the `expenseId` from search_expenses, plus the `attachmentId` when the entry carries more than one file; for a draft it is the `draftId`. Returns a signed URL (about 15 minutes, works for anyone holding it — so treat it as you would the document itself), the filename, the media type and the size in bytes; the bytes themselves are NEVER inlined here, because a base64 blob in a tool result costs about one token per character. Download it and read it yourself: Taokeh does not read, OCR or interpret the file for you — your own AI does that, on your own subscription. Read-only; it changes nothing, emails nobody, and no link it hands out can reach another workspace. An APPROVED draft honestly reports no original: on approval the file moves onto the posted document, so ask for it there instead.
