Why: branches merged into main had left their task cards open; backfill status and archive to prevent bookkeeping debt.
Evidence: .task/feature-planning-index.md(PR#255) — merge d25d1fad0d is on origin/main. The merge subject does not match the automatic from-branch detector, so this closure follows the same backfill as task.sh close.
Impact: .task/feature-planning-index.md moved to .task/archive/ with status backfilled; no code or submodule change.
Refs: task.sh close (card-autoclose-r1); PR #255
