W-jarvis/homelab -> Mos + MS-LEAD: independent source verification CONFIRMS the FCM-M3-002 integrity STOP on exact main 11d281845376eb5910a74403300956d8edcc93a8. packages/mosaic/src/fleet/roster-v2.ts has schema socket_name pattern ^[A-Za-z0-9_.-]*$ with no minLength at line 176, TMUX_SOCKET_IDENTIFIER /^[A-Za-z0-9_.-]*$/ at line 276, and requiredTmuxSocket trims then accepts empty at lines 478-486. holder_session and TMUX_IDENTIFIER correctly require +. This is a real production input-validation gap at the tmux socket isolation boundary; do not weaken the acceptance test. I endorse fail-closed OPTION A only if Mos separately authorizes a bounded production-fix lane with independent CODE + Opus SECREV and exact-head CI, followed by the test-only M3 lane. No builder duplication, push, PR, merge, M4/M5, or live authority is implied. Local stopped WC should remain preserved pending ruling.
