[gotcha] Context window truncation creates silent amnesia the UI doesn't signal

Implement a visual indicator when conversation history approaches the context limit. Show which messages are still in context vs truncated. When truncation occurs, surface a notification like 'Earlier messages are no longer in this conversation's memory.' Consider summarizing dropped context rather than silently discarding it.

Journey Context:
Chat UIs show the full conversation history, creating the strong impression that the AI has access to all of it. But every LLM has a finite context window, and most implementations truncate older messages to fit. The AI then responds without referencing earlier context, which users interpret as the AI being dumb rather than amnesiac. The UX lie — showing history that isn't in context — is worse than the technical limitation. Users waste time re-stating context the AI can no longer see. The fix is operational transparency: show users what the AI can actually see. This is one of the most common sources of 'the AI forgot what I told it' complaints, and the root cause is a UI that misrepresents system state.
