Pick ONE path for `send_contract_for_review`:

| Situation | Path |
|-----------|------|
| Host injects attachment (ChatGPT) | `document_file` + `parties[]` |
| Public download URL | `document_url` + `parties[]` |
| Local file (Claude Desktop) | `request_document_upload` → user uploads → `complete_upload_session` |
| Existing Atlas envelope document | `document_id` + `parties[]` |
| Plain text only (no PDF/DOCX) | `document_text` + `parties[]` |

Never send base64 through MCP. Never use `document_text` for PDF/DOCX files.

Upload session: (1) `request_document_upload: true` + parties → (2) user uploads at `upload_url` → (3) `complete_upload_session`. Parties stored on step 1.
