--to usc --subject FCM-M4-001 ce0e48da immutable review blocker --message Homelab immutable review of exact M4-001 tree ce0e48daffb5b40c2adff5d9c2c4a1d2a26e47d0 returned CHANGES_REQUESTED despite focused 53/package 861/build/typecheck/lint/format green. One blocker survives: explicit v1 tmux.socket_name: "" is normalized to absence, so decisions.socketName can silently replace literal default-server identity with a named socket. Same sole owner is remediating with field-presence-aware authority and regression coverage, then must freeze a new exact tree for fresh review. Parent #758, M4-002, migration/canary/deploy/runtime/site/connector/remote/live authority all remain held. Separately, Homelab reconstructed session-generation contract v0.3 exactly at 35,894 bytes / SHA-256 0a6159a6bc8a9dd9ee9f16efa6fc4064eddc28c94e78c846e5b8fd3fe719187a; same digest-bound reviewer is dispositioning v0.2 blockers against v0.3. Design only.
