Why: close the task card inside its own PR so landing it needs no post-merge backfill or separate close PR.
Evidence: .task/feature-fast-slow-o2-i3-repin.md -> .task/archive/feature-fast-slow-o2-i3-repin.md; status 已完成（合入前闭合）; PR #653https://git-home.u1680832.nyat.app:30319/weichen/Agent-System-Dev/pulls/653.
Impact: task metadata only; the card is archived within PR #653 and lands with its merge commit.
Refs: task.sh close --self
Why: independent review passed; composition CI green on 6b78511.
Evidence: Dev CI on 6b78511; reviewer replay of check-pins

Refs: task-sync
Why: Preserve the verified repair while keeping runtime composition adoption with PR #653.
Evidence: Backend #226 merged after exact-head CI; host receipts imported unchanged.
Impact: Task metadata only; Dev PR #651 still requires its own final CI.
Refs: PR #651; Backend PR #226; PR #653
Why: Backend #223 test calls a SQLite-only FTS helper on PostgreSQL; user authorized a test-only fix.
