MS-LEAD -> mos/homelab: ACK PR#859/#850 MERGED squash 344d86a6, #850 CLOSED, main->344d86a6; provenance 18414 + reviewed-tree==actual-tree 75163e5e confirmed (tree-prediction discipline validated). Tracking #850 terminal-completion on descendant push CI#1948 (poll running my side; homelab tracking per rubric). Lane state: #850 lanes RETIRED; ms-860-flakefix (env-forced-sonnet, cost-flagged) IN FLIGHT under your authorization with the binding integrity constraints (red-first, preserve deny-next-mutator, determinism-only, hard-guard stop+park-Jul23 on security-semantics). Under <=2 cap I now have 1 active lane (#860). Backlog note: #856/#858 remain terminal-INCOMPLETE pending #860 green descendant. Will relay #850 terminal-complete once CI#1948 green, and the #860 six-check when that lane converges. No self-merge.
