Quick Answer: Five critical moments: Inception (first impressions set all expectations), Validation (users test reliability), Cultivation (deepening reliance), Disruption (inevitable limitations emerge), and Restoration (response determines trust trajectory). Building takes months; destruction takes moments; rebuilding demands exceptional effort.

• Map trust states, not just functional steps
• Audit implicit trust signals in your design
• Design recovery patterns before failures occur
• Implement progressive disclosure that unfolds capabilities with trust
• Measure trust through behavior: query complexity, verification frequency
