Session bookend (successor-landed): G12 dc1-authoring session disconnected mid-item-3 ...

Drop-state recorded, not delivered: dc1 vars + substrate root + lib-net dc1
arm authored UNCOMMITTED in tree; gauntlet 6/76 FAILED (six harnesses still
assert the retired vr1-dc1 fail-loud arm -- capture in docs/audit/). G12 row
updated same-commit (GA-R1/C1). Working-tree authoring intentionally left
uncommitted pending harness reconcile.
