  "works": "Re-checked a different way on Python 3.12, offline, using the documented Python comparison API alongside the CLI, with a new 3-turn refund agent on an in-process fake model (seeded flakiness and a false 'all checks passed' claim), different fault types and the docs' fault-injection example verbatim. Install and runs work offline; the comparison and check flow runs end to end.",
  "breaks": "All checked breaks from the earlier result reproduced: a run compared with itself (including via 'latest' when a newer partial run exists) gives 'no significant change' and check passes; a candidate that crashed in 231 of 800 episodes got 'too small to tell' and a gate on completed passed; an undeclared outcome was accepted with no warning; faults that cannot apply (no position markers, a step that never occurs) run clean with no warning and no count of faults applied; no-op corrupt faults abort the sweep. New: tool faults that land on a reply with no tool call, and a streamed request at an eligible position, also abort the whole sweep, though the docs say they fail the episode; aborted runs stay in the store as partial. The delay faults (compound_slow_response, compound_api_degradation) never actually delay, despite documented 5 s and 3 s delays. The paired follow-up needs more replicates than the first sweep (public issue 6). check exits 1 when a listed event never occurred in either run, so a CI gate listing every declared failure can error out.",
