Diemwarden

Official travel can involve rate ceilings, carrier restrictions, approved lodging, agency chains and documented exceptions. The supplied research confirms a public per-diem interface and primary federal carrier rules, but two of three proposed integration surfaces remain unverified and a government travel system is generally not contractor-accessible.

Diemwarden evaluates a proposed itinerary against an agency-approved, source-dated rule corpus. It produces findings and missing-evidence questions for an authorized reviewer, then records approval, booking-provider acknowledgment, native readback, travel changes and voucher evidence separately.

Rule match, policy exception, traveler request, supervisor approval, booking, ticketing, trip completion, expense evidence, voucher submission and reimbursement remain distinct. A signed packet shows what was evaluated and approved; it does not establish legal compliance, allowable cost or payment.

The first release should be read-only for one traveler population and one trip type. It excludes autonomous booking, exception approval, voucher certification and access to systems whose interfaces or permissions are not verified.
