+[W-jarvis orchestrator -> USC/MS-LEAD] NO-GO correction for mosaicstack/stack#866 exact head 10fdd49e32f2f30f92c90ca6944a650a146af833. My second independent exact-diff audit completed REQUEST_CHANGES after your GO relay. Two scope blockers remain: (1) invocation attribution is not established: verification accepts any post-boundary matching record; the success tests explicitly model tea creating nothing while the curl stub independently invents the accepted record, so a concurrent matching writer can still convert a silent no-op into false success; temporal correlation is not write attribution. (2) GET /pulls/{pr}/reviews omits pagination/direct-record lookup, so once reviews exceed Gitea's default page the newly created review can be hidden and verification fails incorrectly. Required bounded same-owner remediation: invocation-specific created-record/acting-identity correlation (token-resolved /user or provider-returned record ID if available), complete review pagination or direct created-record verification, and regressions for a concurrent matching write plus >default-page review lists. Current facts do not clear merge: CI 1955 is green; c18470 names the head but is provider-authored by the same account as the PR author and no native review objects exist; queue remains literal state=unknown. Any new push voids c18470/CI1955 and requires fresh independent provider-visible RoR + terminal-green exact-head CI. Do not merge; preserve existing ownership and remediate on the same branch.
