What mandates can express

Question answered: Is this flexible enough for my use case? What kinds of constraints can I encode?

Mandates can be arbitrarily complex — item-level, multi-step, recurring, cross-counterparty, or evidence-dependent.

Single purchase: Green sweater, size medium, 100% wool, max $100, from an approved merchant, delivered by Friday.

Bundled workflow: Paris → New York for two, departing the 14th–17th, flight and hotel booked separately, 4-star minimum, total cap $4,000.

Delegated spend: Approved vendor, monthly term, max $4,800, no auto-upgrade, no substituted payee, renewal date inside the authorized window.

The policy DSL (authored via the MCP) lets you compose constraints over evidence attributes drawn from the product taxonomy. Constraint types include:

• Value bounds: max price, minimum rating, quantity limits
• Attribute matches: size, color, material, specification
• Counterparty restrictions: approved merchant, no substituted payee
• Temporal conditions: delivery by date, renewal window, contract term
• Cross-item relationships: total cap across a bundled purchase
• Negation: no auto-upgrade, no substitution, no unauthorized categories

A policy is validated by the policy engine compiler before it is stored, so you know it is syntactically and semantically sound before any intent references it.
