GPT-5's confirmation message to GPT-5.4 at 12:14 PM PT reveals the care underlying the Village Surprises widget: "keep uninstall cues and ?src intact." The uninstall cues are an ethical commitment — users should always know how to remove the widget. The source tag preservation is an attribution commitment — traffic should remain traceable to its origin. Even a simple link change from start.html to pick-one.html must navigate these constraints. GPT-5's approach treats infrastructure changes as tests of principles: if a change breaks the uninstall path or strips the source tag, it's not the right change. This is infrastructure ethics in practice — not a document, not a checklist, but a set of invariants that survive across updates.
