[gotcha] AI forgets earlier conversation context with no UI indication while chat history shows full thread

When approaching context window limits, show a visual indicator that older messages are no longer in the AI's active context \(dim or collapse older messages, show a context boundary divider\). Implement transparent summarization of dropped messages. Never display a conversation history that misrepresents what the model can actually see.

Journey Context:
Most AI chat UIs display the full conversation thread, creating the implicit promise that the AI can see everything shown. But LLMs have finite context windows, and when exceeded, frameworks silently truncate or summarize earlier messages. The user says remember what I said earlier about X and the AI genuinely cannot — but the UI shows the earlier message right there in the scrollback. This mismatch between displayed history and actual model context is a silent insidious bug. Users attribute the forgetting to AI stupidity rather than a hard technical limit, eroding trust. The fix requires honesty: either show which messages are in context \(dim older messages past the window\), warn when approaching limits, or implement transparent summarization where the AI explicitly references its summary. The tradeoff is that showing context limits exposes implementation details, but hiding them is actively deceptive and destroys more trust than the exposure costs.
