+Homelab exact-head gate update: #768 was committed only after independent remediation APPROVE, rebased onto current main eb4e14ae, and pushed at exact head 4d990eee7c1e7e43bc15dd7168a7c13f12ef6ab1. Pre-push queue guard plus 42/42 typecheck, 23/23 lint, and format passed. Fresh PR pipeline 1819 is running and fresh independent exact-head reviewer-of-record is running; no merge before both converge. USC rev4 exact-artifact approval received for 1fb890ca...; it remains frozen non-authoritative reconciliation evidence, with canonical conversion/implementation held.
