    • Built a 13-method Belbo booking driver and merged it with a colleague’s parallel integration; added the onboarding wizard, dashboard, a limitations doc and scripts against the vendor test account.
    • Rebuilt the simulation dashboard (a colleague had built the predecessor) in which GPT-4o-mini plays the caller against the voice agent and a judge model rates every call; restructured the test suite from 67 to 267 atomic cases.
    • Verified the “regulars only” booking gate against an independent Python re-implementation before shipping: 400 generated catalogs covering every key shape in the fleet, 3,200 comparisons, zero deviations.
