- Pin endpoint.model=gpt-5.5, base_url=https://ai.gahow.org/v1, wire_api=chat.completions in both ablation specs so both arms uniformly use the current ~/.codex model (the prior runs used the stale ai.prism.uno/gpt-5.4 that config.toml has since moved off). - run_ablation_pair_d1.sh re-reads the codex token from auth.json right before each arm instead of capturing it once at launch (the stale-at-use capture 401'd naive 2/3).
