What: Built-in signature requests for PDFs with signer roles/order, authentication (OTP/SSO or connector), reminders, tamper-evident signed PDFs and audit logs; option to sync signed copies to SharePoint.

Why: We need formal approvals for SOPs/CAPA/contracts; external tools break traceability and complicate audits.

Benefit: Keeps the full author → review → sign → publish lifecycle in ClickUp, improving compliance and reducing manual handoffs.
