Why: CF-A lands in backend (ctxasm backfill + facade cards) and documents.
Evidence: backend commit recorded in module log; combination make test in
task card.
Impact: gitlink-only.

CF-A(提案 D46/D47)落地:artifact 统一。backend PR #29(ctxasm 回填对称 + 门面卡)与 documents PR #29(usage 指南)已合入;本 PR 钉定组合并回填任务卡。前端零改动(docBridge 已解析 doc-ref,门面卡开箱即用)。
验证:模块与组合 make test 均退出码 0(task-sync 0be23f9a→b8a06cd)。最后一期 CF3(跨会话收件箱)另立卡。
