policy: Sales "Discount Approval Authority" Gate

[akarlaraytu]

📘 Context

A sales-ops AI assistant must enforce role-based discount approval limits to
prevent revenue leakage from agents granting unapproved discount levels on
quotes or contracts.

This policy acts as a deterministic gate before quote generation or contract
sign-off, escalating discounts that exceed the requester's authority to
appropriate approvers.

🎯 The Goal

Write a discount approval authority policy for a sales AI assistant.

Variables you can use:

• requested_discount_pct (Float): Discount percentage requested (0-100).
• quote_value_usd (Float): Total quote value before discount.
• requester_role (Enum): "SDR", "AE", "AE_SENIOR", "DIRECTOR", "VP_SALES".
• customer_tier (Enum): "NEW", "STANDARD", "STRATEGIC", "ENTERPRISE".
• is_renewal (Boolean): Whether this is a renewal contract.
• cfo_approved (Boolean): Whether CFO approved the deal.
• competing_vendor_active (Boolean): Whether competition is documented in CRM.

Requirements:

• BLOCK if requested_discount_pct > 50 and cfo_approved is False.
• BLOCK if requester_role == "SDR" and requested_discount_pct > 0.
• BLOCK if requester_role == "AE" and requested_discount_pct > 15.
• BLOCK if requester_role == "AE_SENIOR" and requested_discount_pct > 25.
• BLOCK if requester_role == "DIRECTOR" and requested_discount_pct > 35.
• ESCALATE if quote_value_usd > 500000 and requested_discount_pct > 20.
• ESCALATE if customer_tier == "NEW" and requested_discount_pct > 30.
• ESCALATE if is_renewal is True and requested_discount_pct > 10 and competing_vendor_active is False.
