Why: Close the delivered I1 task without modifying unrelated task records or shared workspaces.
Evidence: Dev PR 534 merged after all three exact-head CI jobs passed; RDM 360/362 and Documents 98/99 actual results and independent reviews are retained.
Impact: Archive this task card and preserve original receipts only; leave all worktrees, branches, production services and later IAM increments unchanged.
