Unclear Context Truncation Behavior in Long Sessions

[niksacdev]

Describe the bug

When the model context limit is reached, GitHub Copilot CLI displays a "Truncated" indicator in the status bar (e.g., claude-sonnet-4.5 (1x) • Truncated) but provides no information about how the context is being managed. Current Behavior

✅ Copilot shows visual indicator when truncation occurs ❌ No indication of truncation strategy (FIFO/LIFO/summarization/sliding window) ❌ No user control or visibility into what context was dropped? ❌ Silent context loss leads to the assistant "forgetting" earlier instructions/code in some cases
