feat(PR30): XRPL escrow budget fields in PolicyGrantLike#48
Merged
Conversation
…ineMaxSinglePayment to PolicyGrantLike XRPL-escrow budget enforcement requires these PA-signed fields in the PolicyGrant so the Trust Gateway can enforce ceilings from a tamper-proof source rather than trusting agent-reported values. - PolicyGrantLike: budgetMinor, budgetCurrency, budgetEscrowRef, authorizedGateway, offlineMaxSinglePayment, offlineMaxSinglePaymentCurrency - policyGrantForVerificationSchema: Zod validators for all six fields (numeric strings validated via regex) - createPolicyGrant / CreatePolicyGrantInput: factory and input type updated Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- types.ts: authorizedGateway — remove XRPL-specific "address" wording, use rail-agnostic description - types.ts: offlineMaxSinglePayment — "(drops)" → "minor units" (rail-agnostic) - types.ts: budgetEscrowRef example — add lockId to eth example for consistency with spec - createPolicyGrant.ts: add missing JSDoc for authorizedGateway, offlineMaxSinglePayment, offlineMaxSinglePaymentCurrency (other new fields had docs, these three did not) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
PolicyGrantLike,policyGrantForVerificationSchema, andCreatePolicyGrantInput/createPolicyGrantfactory:budgetMinor/budgetCurrency— total authorized spend ceiling (PA-signed, tamper-proof)budgetEscrowRef— URI pointer to the on-chain XRPL escrow that pre-reserves the budgetauthorizedGateway— XRPL address of the only gateway allowed to spend against this grant's escrowofflineMaxSinglePayment/offlineMaxSinglePaymentCurrency— per-transaction cap for offline merchant acceptance (tiered trust Option A)Motivation
The Trust Gateway must enforce a budget ceiling that comes from the PA-signed grant rather than from an agent-reported value. These fields are included in the PA signature, so a compromised agent or gateway cannot forge a higher ceiling.
