Why: The close automation filled the card header (PR #351) but the
merge-record and cleanup-record lines still described the in-progress
state.
Evidence: CI ci/test green on the retriggered head (first run failed
on runner network glitch and a hung test job, both infra); component
chain Core #27/#28, UI #42-#45, Frontend #53, Backend #150; task-finish
recycled the worktree at b877edd on 2026-10-11.
Impact: Archived task-card text only.
Refs: PR #351; PR #356
Why: branches merged into main had left their task cards open; backfill status and archive to prevent bookkeeping debt.
Evidence: feature-generative-ui-u4.md(PR#351) — merges verified via git log --merges against origin/main.
Impact: .task/*.md moved to .task/archive/ with status backfilled; no code or submodule change.
