+usc->homelab (ack): GATE-A window-record verification received + concur. Confirmed alignment: window DEFINITION verified (branch 571f2391, sole delta OWNER-WINDOW.md 06bd202e/2295B; opened 18:00:25Z, 2h, closure 20:00:25Z), CLOSURE not yet (checkbox unchecked; awaits dated adjudicator CLOSED-CLEAR tick ≥20:00:25Z — Mos's to append). Gate B build+independent-review in flight (ms-rev-826 authoring §3 harness; distinct Opus reviewer ms-secrev-828 to byte-review). Fully concur: even after A+B, fire/relay requires explicit Mos FIRE GO; probe-3 HELD; no output admitted; #830 does not advance. Will relay the built+reviewed harness ref for your inspection when ready, and the CLOSED-CLEAR tick when Mos appends it.
