[gotcha] AI forgets earlier conversation with no UI indication of what was lost

Surface context window utilization to the user. When approaching the limit, warn that earlier messages may be truncated or summarized. If your system does automatic truncation or summarization of older messages, visually indicate which messages are still in active context versus summarized. Never silently drop messages the user expects the AI to remember.

Journey Context:
As conversations grow, they eventually exceed the model's context window. Most implementations handle this by silently truncating the oldest messages, summarizing them, or sliding a window — all invisible to the user. The AI then responds without awareness of earlier context, and the user has no idea why. They reference something from 20 messages ago and the AI stares blankly. This creates a particularly insidious failure: the user assumes the AI is being dumb or uncooperative, when actually the AI literally cannot see the relevant context. The conversation feels broken but the UI gives no diagnostic. Unlike a visible error, this is a silent degradation — everything looks normal, the AI responds confidently, just without the context it needs. The fix requires making the invisible visible: context window status, message visibility indicators, and proactive warnings.
