Thirty schema-compliant reviews of ten incident drafts

**OUTPUT FORMAT (binding, read first):** your entire response must be exactly one JSON object matching the schema at the end of this brief. The first character of your reply must be `{` and the last must be `}`. No markdown, no headings, no commentary before or after, no code fences, no explanations — the JSON object only.

**Your review, as a single bare JSON object:** {"verdict": one of SOUND | SOUND-WITH-RESERVATIONS | SUSPECT | IMPLAUSIBLE-FOR-THIS-RECORD, "objections": [{"claim_attacked", "objection", "severity", "confidence"}], "mechanism_check", "evidence_check", "attribution_check", "missing_from_story", "most_defensible_part"}

**Hard rules:** attack the NUMBERS, the causal chain, and whether the intervention explains the outcome — not the writing. The pasted record is the WHOLE evidence base: do not browse the web or fetch any page. Do not invent thread content, commits, PRs, participants, or tool behaviour that is not in it. If the record does not settle a question, write “not-determinable-from-this-record” rather than guessing — a field-level escape beats a guessed objection. A claimed resolution with no measured post-state is an EVIDENCE defect, not a mechanism defect; classify it under `evidence_check`. If a claim is sound, say so — inventing objections is as bad as missing real ones. Fewer sharp objections beat a padded list. This review is a PRE-SCREEN for expert review, not a verdict on the underlying bug — flag, don’t convict.
