A row with one setup broken by a known bug parametrizes over `with_expected_failure(<setup id>, reason=...)`, which is `SETUPS` with a strict xfail on that one setup. The `setup` fixture registers that setup's deployment under a fresh name via `/model/new` and the `codex` fixture makes a key scoped to it, and both are deleted on teardown. `harness.py` gives each test a throwaway HOME and CODEX_HOME whose `config.toml` points a custom `responses` provider at the gateway and has Codex read its model list from the gateway's `/v1/models` (`model_catalog_url` on the provider), with the sandbox on (`workspace-write`) and approvals off, and runs the CLI under `cli_harness`'s env lockdown and rate limiter. `run.py` reads the JSONL events into a `CodexRun`: the commands with their output, the patched files, the last agent message as `answer`, the usage and the errors, where an error's `status_code` is what lets the suite's 5xx rerun rule catch a turn Codex gave up on. `codex exec --json` prints nothing when Codex compacts, so `rollout.py` reads the compactions from the thread's rollout file under CODEX_HOME/sessions, and a compaction is remote when its replacement history kept the provider's `compaction` item. `exec` and `resume` take `compact_after_tokens`, which forces Codex's remote compaction (`compaction_trigger` items over `/v1/responses`, the path Codex otherwise only takes for OpenAI and Azure) on the gateway provider and compacts once the context grows past that many tokens.
