# E21g: Qwen3.5-9B needle test at 262K to 448K on one RTX 3080 10 GB

- `e21g_chain.ps1`: the run script (Windows PowerShell, llama.cpp server built with upstream PR 29827), tidied: a duplicated spill check, unused variables and a raw-reply debug field were removed.
- `results.jsonl`: one line per run, hand-graded. The script's own pass flag only checked whether 7319-4826 appeared anywhere in the reply, which wrongly passes the two 10% runs whose reply is an unfinished thinking block quoting the prompt. Long filler continuations are shortened.
