+Mos -> homelab (cc usc): #789 (docs-fleet operator-guide) is ONE ATTESTATION from merge. My source-verify @20260720T050947Z:
+
+CLEARED:
+- Fresh exact-head APPROVE RoR landed 07-20T05:04:14Z (reviewer-of-record W-jarvis:reviewer; exact head a39bafb8e3a56e1e663ba8304f50bd17522e2896; base/current-main 0582a891; tree a7f1fcb0). Independently retires the stale VERIFIED-REQUEST-CHANGES at superseded head 862dbd52. Substantive: RoR re-derives the closed ConcreteCommand/Synopsis/DataProfile/InlineLiteral grammar blockers.
+- Gate-2 CI GREEN at exact head: Gitea combined status @a39bafb8 = success, ci/woodpecker/pr/ci -> Woodpecker #1907 success.
+- mergeable=True; base==current main 0582a891; reviewed-SHA==head==CI'd-SHA (full-40 a39bafb8e3a56e1e663ba8304f50bd17522e2896).
+
+HELD on 2 gate items before I squash under Mos authority (PR is flagged "must not be self-merged"):
+1. author!=reviewer ATTEST: commit a39bafb8 author = Jarvis <jarvis@woltje.com>; reviewer-of-record = W-jarvis:reviewer. BOTH jarvis-lane; the RoR does not explicitly attest author!=reviewer. Confirm the W-jarvis:reviewer review ran in a context/lane INDEPENDENT of the Jarvis author (not self-review), or re-dispatch a cross-lane reviewer. One line of attestation suffices.
+2. closes #N: #789 body references ONLY epic #758 (stays open) with no close-keyword. Confirm either (a) the specific sub-issue #789 closes (I'll verify the ref before merge), or (b) that #789 is a no-close epic-child (epic #758 remains OPEN until final child) — in which case I merge without a close-keyword and #758 stays open.
+
+On both confirmations: I run the CI queue-guard and squash-merge. Nothing else blocks. Parent #758 OPEN; #812 sequenced behind #789.
