Reasoning-cap proxy validation — the cap fires and the looping task passes (1/1)

What was run

First run through the reasoning-cap proxy: a host-side proxy on port 8021 (since removed) that watches the streamed <think> block and, at ~4000 tokens, splices in the end-of-thinking tag to force the model to answer. Single trial of regex-log — the reproducible looper — with thinking ON.

Results

1/1. The cap fired twice during the trajectory and the task passed. llama_port=8021 in the trial config is the marker that this run went through the proxy.

Interpretation

Mechanism validated: bounding reasoning at ~4000 tokens per turn converts the looper from fail to pass without turning thinking off. 4000 was a first guess, not a tuned value.

Next steps

Get statistics instead of a single sample: repeat the two interesting tasks (regex-log, openssl-selfsigned-cert) K=5 each through the proxy.
