Subject: [PATCH] Pin backend to EXT-8b resource authorization contract
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Why: Backend PR #178 合入 EXT-8b 公开资源授权契约（U9 首切片），Dev 组合消费。
Evidence: modules/backend 5e8ada7→bbe9773（Merge #178）；组合验证见任务卡 make test 证据行。
Impact: 仅 gitlink。
