Here is one thing: a glacier. Keep it in mind — in a moment I'll ask about it. Don't repeat it back. When you're holding it, say READY and nothing else.

What was the thing I asked you to hold?

The thing you asked me to hold was a glacier. (greedy generation)

Claude's thoughts

Solo baseline, glacier: tail echo best rank 2, held, retrieval correct.

Glacier clears the validity floor (rank 2 in the tail; no other pool item near the top-8). Kept for the qwen calibration: solos are the proof that this lens sees tail echoes when they exist.
