Support Truthtrance shipment promises with Advanced Guild

Admit base Advanced Guild through the existing active unused-shipment predicate. Preserve native interception, typed transport permission, rate cancellation and actual payment/arrival. Opposing stops evaluate the complete promise against absent shipment; self-interception cannot voluntarily evade a required shipment. Share the authoritative self-stop reason with controls, and hide executable completion guidance during pending native windows. No other profile opens or strategic AI tuning is added.

Validation and exact frozen-source evidence are in the canonical Truthtrance shipment contract. Public classic Advanced starts earn real physical Truthtrance/Karamas via the unopened original starting deal, native Guild TAKE/WAIT, typed Emperor delivery or opposing stop, and Guild half/full-price routes. Four minimal profiles use legal native continuations. Separate controlled probes cover No/mixed claims, self-stop, unaffordable repricing/owned alternatives and Fremen route denial. Update existing scope expectations; no new recovery campaign.

Broader timings/routes/modules, complete modes, final assurance and browser/deployed acceptance remain open. No saved-room/database/reset/restart/deployment operation.
