Why: Close automation filled the header (PR #408) but merge/cleanup
lines still described the in-progress state.
Evidence: CI green on PR head (one 405 race auto-resynced);
task-finish recycled at e80baf1 on 2026-10-12.
Impact: Archived card text only.
Refs: PR #408; PR #409
Why: branches merged into main had left their task cards open; backfill status and archive to prevent bookkeeping debt.
Evidence: feature-generative-ui-u6.md(PR#408) — merges verified via git log --merges against origin/main.
Impact: .task/*.md moved to .task/archive/ with status backfilled; no code or submodule change.
