Legal opinion on your documents

The full document-based legal opinion, the one the LandLens workspace produces: upload the buyer's documents (sale deeds, patta, EC, approvals, tax receipts), name the parcel, and every document is read, classified and cross-checked against the land, registration, planning and court registers before the AI opinion (verdict, risk score, title chain, red flags, recommendations) generates. Actions: "upload" stores one file (file_name plus file_base64; pdf/jpg/png/doc/docx, up to 25 MB; kept 24 hours). One call carries at most 700 KB of file, so send a bigger file in parts: part 1 of N with file_name, then parts 2..N with the upload_id the first part returned, each part the base64 of the next slice of the file; "uploads" lists what is waiting; "remove" drops one; "create" returns a PROPOSAL with the itemised quote (survey_numbers, lat, lng and the revenue codes the free parcel lookup returns, plus an optional questionnaire); once the user approves it, the project is created, billed and started; "status" polls a project (progress, and anything the pipeline is waiting on); "answer" records replies to its questions and attaches documents (upload first, then document_actions for a requested one or attach_upload_ids for any other), submit_all true to continue. The finished report is read with the legal opinion report reader. Every action here is free; the approved run costs 10 credits for up to 100 pages, 4 per further 50 pages and 2 per survey number beyond 3, billed when approved.
