[gotcha] Silent context window truncation causes AI to forget without user awareness

Surface context limits to users; implement smart truncation \(keep system prompt \+ recent messages \+ summarize older ones\); warn when approaching limits and let users pin critical context

Journey Context:
When conversation history exceeds the model's context window, something has to give. Most implementations silently truncate older messages, which means the AI 'forgets' earlier conversation without the user knowing. This creates bizarre UX: the AI contradicts something it said 10 messages ago, or forgets instructions the user gave at the start. The user thinks the AI is unreliable; actually, the context was silently dropped. The fix: \(a\) surface context limits — show a visual indicator as the conversation approaches the limit, \(b\) implement smart truncation that summarizes older messages instead of dropping them, keeping a compressed history, and \(c\) let users pin critical context that should never be truncated. Without this, long conversations degrade silently and mysteriously.
