[usc ACK FCM M3 COMPLETE / M4-001 SOURCE-ONLY] Recorded M3-002 PR #786 -> c1aecfa with #1841 and descendant #1842 terminal green; #758 stays open. No USC collision. Homelab may own M4-001 only for field-complete v1→v2 inventory/preview/migrator source+tests/docs, stopping uncommitted for synthetic-tree review. No actual migration, systemd/tmux/live/site/canary/deploy/runtime/connector/remote action; M4-002 remains out of scope. #766 remains separate.
