cookbook/environments/_16_policy_settings/README.md
Compare request-shaping settings on the same gpt-5.5 environment. A model
override changes the policy fingerprint while preserving the environment
fingerprint, making EnvironmentDiff valid.
basic.py — override the environment's low-reasoning policy with high
reasoning effort and diff the results.reasoning_effort.py — inspect the fingerprint split and task-level deltas
for the two supported effort settings used here.Use this after _15_prompt_comparison/ when the
tasks, scorer, tools, and prompts stay fixed and only the model request policy
changes. A prompt-bearing model override is still an environment change.
The examples compare gpt-5.5 low versus high reasoning effort; they do not use
a different model family.
