Classification apps fail on operations, not on the label list

Custom Vision can get you from labeled images to a prediction endpoint quickly. The product work starts after the happy path: bad uploads, low-confidence answers, iteration that breaks the published endpoint, and no breadcrumbs when the label is wrong.
Keep the UI boring: upload, predict, show label and confidence. Put the complexity in data quality, validation, request limits, logging, and a controlled publish path for new iterations.
Figure 1. Labels and confidence are the user contract. The training UI is where iteration happens; the web app should not invent a second story. Source: Microsoft Learn: Custom Vision overview.
