[gotcha] AI silently loses earlier conversation context with no UI signal as context window fills

Track cumulative token usage against the model context window limit. When approaching 70-80% capacity, show a subtle warning that earlier context may be dropped. When older messages are truncated or summarized, explicitly indicate which messages the AI can still reference. Implement a visual context timeline or indicator showing what is in-window versus out-of-window. Consider auto-summarizing older context rather than silently dropping it.

Journey Context:
As conversations grow, they exceed the model context window. The typical implementation silently truncates older messages to fit. The user has no idea the AI has forgotten earlier instructions, leading to responses that contradict or ignore established constraints. This is especially dangerous when users set important constraints early such as always use Python 3.9 or never suggest paid tools that get silently dropped. The AI does not know it forgot — it just responds to what it can see. The failure is invisible until the AI violates a previously established constraint, at which point the user assumes the AI is unreliable rather than context-limited. The fix requires the UI layer to track context consumption and signal when earlier context is at risk or has been dropped. Most teams never implement this and only discover the issue from confused user reports about the AI forgetting things.
