+阶段结果（2026-08-29）：全范围终审补齐三项契约：`SourceSnapshot` identity 绑定返回字段、行上限和截断状态；显式空 `dc_member` 分区持久化为 `membership_unknown`，生成 unavailable 聚合并强制 publication 为 partial，只重试成员来源且绝不替换 last-good；HTTP 与前端把排名百分位统一收紧为 `(0, 100]`。新增迁移 head `0006_membership_unknown`，离线升级 SQL 已核对。最终后端 Ruff、Pyright 和全量测试为 139 passed、3 skipped，跳过项均需要 `ZHIXING_TEST_DATABASE_URL`；前端 format、lint、typecheck、全量 64 项 Vitest 与 build 通过，build 仅有既有单包大于 500 kB 的非阻塞提示；`./dev.sh check`、`./dev.sh test` 和开发/生产、默认/jobs 四种 Compose `config --quiet` 均通过。Compose 验证显式清空 `ZHIXING_TUSHARE_TOKEN` 并使用无敏感信息的占位数据库 URL。真实 PostgreSQL 集成、真实 Tushare capability、生产网络和部署权限仍未在本机环境验证，不将其误报为通过。全范围只读复核最终为 no blocking findings。经 `trellis-update-spec` 评估，unknown-membership 与快照 identity 属于可提升的候选知识，但用户未批准写 `.trellis/spec/`，本任务仅在设计、测试和本执行记录中保存。
