 | `review.attribution`        | boolean | Append the attribution footer naming the model and CLI version (e.g. `_— qwen3-coder via Qwen Code /review (v0.21.2)_`) to review bodies and inline comments posted by `/review`. Disable to post reviews without visible AI attribution: the footer is omitted and posted comments and body lists lose their `**[Critical]**`/`**[Suggestion]**` markers. The posts stay identifiable in the raw source: each carries an invisible severity marker (`<!-- qwen-review critical -->`) and the review body carries a ledger marker (`<!-- qwen-review-ledger ... -->`) — anything reading comment bodies (GitHub API automation, the workflows this setting couples to) still recognizes a `/review` artifact, and presubmit duplicate detection recognizes the reviewing account's earlier posts by the severity marker, though unattributed posts from other accounts escape it. Another consequence: qwen-autofix's Critical-only mode (engaged after round 5, or earlier when a counting window's diff-growth budget trips) no longer recognizes the posted findings as Critical and defers them. Disabling also withholds the model from the machine-ledger marker embedded in the review body, so in a fresh environment (CI, another clone — anywhere without a review cache) the incremental anchor recovered from the last posted review fails the same-model check and the re-review falls back to full-range. | `true`      |

 | `review.reverseAuditRounds` | number  | Lower the reverse-audit loop's round cap for every high-effort review. The cap otherwise follows the diff topology (10 small / 5 chunked; a huge diff is 3 with a review deadline and 5 without). This can only **lower** whichever tier applies: a value below 3, above the tier, or not a whole number above zero is ignored. Cutting the cap does not make reviews converge sooner — the loop ends on two consecutive dry rounds — it makes them stop before converging more often, and every such stop caps the verdict at Comment.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 | `0` (unset) |
