+# Bell 独立纵切验收
+
+本验收只使用 Bell 自身、临时 PostgreSQL 和项目内合成事件，不启动或调用 Sense、Brain，不连接默认 5432、生产数据库或客户数据。
+
+## 固定工具链
+
+```powershell
+$env:GOTOOLCHAIN='go1.26.5'
+go version
+node --version
+corepack pnpm@9.15.1 --version
+```
+
+预期分别为 Go 1.26.5、Node 22.22.1、pnpm 9.15.1。
+
+## 源码验证
+
+```powershell
+Set-Location Bell\server
+$env:GOTOOLCHAIN='go1.26.5'
+go test ./... -count=1
+go vet ./...
+go build ./...

+
+E2E 自动完成并清理：临时 PostgreSQL、随机数据库/HTTP 端口、随机管理员/处置员凭据、迁移、健康检查、登录/RBAC、最小 Bell 菜单、规则、合成 Event/Receipt 幂等、Alert、20 路并发 ack、越权/缺参拒绝、close 重放幂等、两条生命周期时间线、冷重启、Windows stop 和日志泄密检查。原始包保持生产配置并先通过审计；业务自动化只把临时包副本切换为 `dev` 测试模式。生产验证码的获取、正确登录、错误及重放拒绝由 #138 的 `Bell/server/tests/bell_production_login/run-postgres.ps1` 覆盖，不暴露或识别验证码答案。
+
+浏览器验收打开脚本输出的临时 `base_url`，检查：
+
+- 匿名访问跳转登录页，并显示验证码输入；测试模式可填写任意非空验证码，生产验证码行为由 #138 回归覆盖；
+- 登录后保留 GoAdmin 侧栏、顶部导航和标签页；
+- 管理员显示 Bell 必要业务菜单，包括预警管理、事件查询、规则配置；处置员仅显示预警处理所需入口；
+- 预警详情可显示关联事件、处理人、现场结果和两条处理时间线；
+- 不显示开发工具、定时任务、系统监控等无关入口。
+
+## 仓库闭环
+
+```powershell
+python dev_scripts/harness.py check --strict
+git diff --check
+git status --short --branch
+```
+
+浏览器人工/工具检查、真实生产数据库、客户网络和长期负载不由 API 单测替代；未执行的项目必须在工单证据中明确说明。

+# Bell Windows 运行说明
+
+Bell Windows 包包含独立后端、GoAdmin 管理端静态资源和启动、停止、检查脚本。正式运行需要独立 PostgreSQL；包内不提供默认账号、密码、JWT secret 或数据库。
+
+## 配置
+
+编辑 `config\bell.env`：
+
+```text
+BELL_HOST=127.0.0.1
+BELL_PORT=18090
+BELL_WEB_HOST=127.0.0.1
+BELL_WEB_PORT=18091
+BELL_DATABASE_URL=host=127.0.0.1 port=5432 user=bell dbname=bell sslmode=disable
+BELL_JWT_SECRET=<至少 32 字符的独立随机值>
+BELL_BOOTSTRAP_USERNAME=<仅首次迁移使用>
+BELL_BOOTSTRAP_PASSWORD=<仅首次迁移使用，至少 8 字符>
+BELL_AUTO_MIGRATE=true
+BELL_SYNTHETIC_EVENTS_ENABLED=false
+```
+
+不要把真实配置提交到 Git。首次迁移成功后，建议从进程环境中移除 `BELL_BOOTSTRAP_PASSWORD`；它不会写入明文数据库。
+
+## 启动、检查和停止
+
+```bat
+check-bell.bat
+start-bell.bat
+check-bell.bat -Running
+stop-bell.bat
+```
+
+浏览器访问 `http://127.0.0.1:18091/`。`BELL_PORT` 是仅供本机 Web 网关访问的后端端口；`BELL_WEB_PORT` 是用户访问入口。启动脚本默认先执行幂等数据库迁移，再启动后端和 Web 网关；任一步失败都会返回非零退出码。
+
+`stop-bell.bat` 只按包内 PID 文件和启动命令行核对后停止本包进程树，不按端口终止未知进程。运行日志位于 `runtime\logs`，不得包含密码、JWT 或登录 token。
+
+## 构建和包审计
+
+从仓库根目录运行：
+
+```powershell
+Bell\scripts\build\build-windows.bat
+pwsh -NoProfile -File Bell\scripts\build\test-package.ps1 -PackageRoot Bell\dist\bell-windows-amd64
+```
+
+输出：
+
+- `Bell\dist\bell-windows-amd64\`
+- `Bell\dist\bell-windows-amd64.zip`
+
+包内 `VERSION.txt`、`MANIFEST.sha256` 和 `LICENSES\` 分别记录源码提交、工具链、文件摘要、GoAdmin 来源及 MIT 许可证。
+
+## 常见错误
+
+- `BELL_DATABASE_URL is required`：设置独立 PostgreSQL 连接串。
+- `PostgreSQL is unreachable`：启动 PostgreSQL，并检查地址和端口。
+- `BELL_JWT_SECRET must contain...`：生成至少 32 字符、只供 Bell 使用的随机值。
+- `port ... is already in use`：停止已有 Bell，或修改后端/Web 端口。
+- `Bell database migration failed`：检查数据库是否存在、用户权限及迁移日志；不要删除已有 Event、Alert 或生命周期事实。

 E2E 入口从 PowerShell 7 调用时会自动转入 Windows PowerShell 5.1 执行本地 HTTP 回归；源码打包仍显式使用冻结要求的 PowerShell 7。这样与 Windows 交付脚本的宿主一致，也避开当前机器 PowerShell 7 HTTP 客户端对本地 Go/MediaMTX 响应的兼容问题。
 
+默认入口只复制 Git 已跟踪的 `Sense/` 源码到系统临时目录，因此正常开发工作区中已有的 `node_modules`、`dist`、本地配置、日志和其他未跟踪文件不会进入验收副本。`-PreparedPackageRoot` 也会先把指定包复制到本次临时目录，运行时配置、浏览器脚本、截图和日志不会写回原包或源码树。
+
+Sense 进程提前退出或 HTTP 就绪超时时，脚本返回非零并输出阶段、退出状态、临时日志位置和经过过滤、截断的日志摘要；数据库连接、密码、token、Cookie、JWT 和 credential key 不得出现在诊断中。默认无论成功或失败都会清理所属进程和临时目录；`-KeepTemporary` 仅用于排错，仍会停止进程，但保留目录可能包含随机运行时秘密，必须限制访问并在排错后安全删除。
+
+为避免 Windows 首次扫描临时复制的 MediaMTX 二进制占用产品固定的就绪窗口，E2E 会先在同一动态端口和临时配置上启动一次包内 MediaMTX，确认 Control API 可用并完全停止，再由 Sense 以 managed 模式启动并完成生命周期验收。预检失败会单独报告 `MediaMTX preflight` 阶段，不会被误报为 Sense HTTP 超时。
+
+HTTP、RTSP、HLS、Control API 和 ONVIF 动态端口使用 TCP 绑定探测；WebRTC 本地 UDP 端口必须使用 UDP socket 实际绑定探测，不得用 TCP 空闲结果代替，避免落入 Windows 的 UDP 排除或占用范围。

+# Standard event contract v1
+
+`yovision.event/v1` is the only shared representation of an anonymous safety event. It is an immutable fact, not a Bell Alert. Bell owns all rule matching, Alert, acknowledgement, close, notification and user/audit state.
+
+## Identity and idempotency
+
+The permanent idempotency key is the exact UTF-8 pair `(producer_id, source_event_id)`. `producer_id` always names the original producer. A Sense gateway/relay sends its own authenticated transport identity and optional `X-YoVision-Relay-ID`, but it must forward both key fields and the business payload unchanged. A retry is not a new event.
+
+After schema validation, calculate `payload_sha256` from the RFC 8785 JSON Canonicalization Scheme representation of the complete Event. The checked-in vector fixes the expected digest for supported implementations. Bell stores key, digest and Bell `event_id` permanently:
+
+- absent key: atomically create Event/Receipt and return `201` with `disposition=created`;
+- same key and digest: return the original `event_id` and digest with `200`, `disposition=duplicate`;
+- same key but another digest: return `409 idempotency_conflict`, append an audit fact, and mutate neither Event nor Alert;
+- identity lookup and insert must share a transaction/unique constraint so concurrent duplicates have the same result.
+
+Canonical timestamps in Event v1 are UTC RFC 3339 with exactly three fractional digits and `Z`. Optional members are omitted, never sent as `null`. Producers must reject non-finite numbers before canonicalization.
+
+## Mapper responsibilities
+
+| Role | Required responsibility | Must not do |
+|---|---|---|
+| Brain producer mapper | Convert `brain.internal.event-candidate/v1` into stable original identity, logical site/device/profile/rule/region refs, model version and anonymous observation; generate one `source_event_id` once and persist/reuse it across retries. | Expose internal candidate fields, face/person identity, camera credentials, file paths, Alert state, or regenerate identity during retry. |
+| Sense producer/evidence mapper | When Sense originates an event, apply the same original-identity rule; map its internal evidence record to a logical evidence reference and own later status resolution. | Put local path, RTSP URL, signed URL, credential or Outbox attempt ID into Event. |
+| Sense relay | Authenticate as a transport hop, preserve original `producer_id`, `source_event_id` and payload, retain retry/audit state outside the Event, and return Bell's response unchanged enough for deterministic retry handling. | Replace producer identity, create a new source ID, enrich/reorder semantics, or treat `409`/`422` as a transient retry. |
+| Bell consumer mapper | Validate before persistence; canonicalize; enforce permanent idempotency; map the immutable shared Event into Bell's private Event/Receipt and then independently evaluate rules to create an Alert. Unknown evidence becomes degraded evidence, not a rejected Event. | Persist arbitrary extension fields, import producer internals, or accept shared ack/close/notification/user state. |
+
+Field ownership is deliberately narrow:
+
+| Contract fields | Authoritative writer | Relay/Bell responsibility |
+|---|---|---|
+| `schema_version`, `producer_id`, `source_event_id` | Original Brain or Sense producer mapper | Relay preserves; Bell uses version gate and permanent idempotency key. |
+| `site_ref`, `device_ref`, `profile_ref` | Producer mapper from versioned logical configuration | Relay preserves; Bell treats as opaque external refs. |
+| `event_type`, `occurred_at`, `severity`, `rule`, `model`, `observation`, `region` | Brain/Sense mapper at the detection decision | Relay preserves; Bell validates and stores the immutable snapshot. |
+| `evidence[]` identity and initial status | Evidence-owning producer, normally Sense | Relay preserves; Bell stores the Event snapshot and resolves current metadata separately. |
+| `X-YoVision-Relay-ID` | Authenticated Sense transport hop | Bell audits transport metadata outside the immutable Event. |
+| `event_id`, `disposition`, `payload_sha256` | Bell ingest boundary | Producer/relay retain the receipt for deterministic retries. |
+
+## Errors, compatibility and fallback
+
+- `400 invalid_event`: schema, canonical form, or sensitive/unknown member violation. Terminal until the producer fixes the payload.
+- `409 idempotency_conflict`: same permanent key with a different payload. Terminal and audited; never overwrite the first Event.
+- `422 unsupported_schema_version`: unknown major/revision. Terminal for that payload.
+- Evidence `pending`, `processing`, `success` and `failed` are valid Event states. Bell keeps the Event and resolves/degrades evidence independently.
+
+v1 is closed (`additionalProperties=false`). Producers may enable a compatible revision only after all relays and Bell validate it. Any removed/renamed required field, changed meaning, enum narrowing, identity/canonicalization change, or new required member publishes a new major path such as `/v2`. During the compatibility window Bell keeps the previous version endpoint. Rollback disables the new producer version and resumes the last accepted version; it does not delete Event, Receipt, Outbox or audit facts.
+
+Unknown-version fallback is explicit: Bell returns `422`; relay records the terminal rejection without rewriting the payload; producer may remap the same internal candidate into a supported v1 payload only if it has not previously assigned that `(producer_id, source_event_id)` to a different canonical payload. Otherwise it must stop and require operator reconciliation.
+
+## Reproducible verification
+
+No third-party package is needed:
+
+```powershell
+python contracts/tests/events-v1/test_contract.py
+python contracts/tests/evidence-v1/test_contract.py
+```
+
+The tests validate Schema/OpenAPI references, mapper fixtures, RFC 8785-compatible canonical vectors used by v1 examples, duplicate/conflict behavior, unknown versions and sensitive-field rejection.

+# Evidence reference contract v1
+
+This contract shares metadata about a logical evidence object. It never grants object access. `owner_id` identifies the service that owns resolution; `evidence_id` is opaque to every consumer. Neither field may be interpreted as a URL or local path.
+
+## State and degradation
+
+- `pending`: capture was accepted but no processing started.
+- `processing`: capture or encoding is in progress.
+- `success`: capture completed; `content_type` and SHA-256 `integrity` are required. Access authorization is negotiated outside this payload by the machine-identity/connector work.
+- `failed`: `failure.code` and `retryable` are required. Bell keeps the immutable Event and renders evidence unavailable; it must not reject or close the Alert because evidence failed.
+- HTTP `404` means an unknown logical reference. `410` means expired evidence. Both degrade evidence only, not the Event.
+
+The payload forbids arbitrary properties, so filesystem paths, camera credentials, bearer/user tokens, signed URLs, face templates and notification/Alert state fail schema validation. Do not add access URLs to v1. A short-lived download grant, if later required, needs a separately reviewed endpoint and security contract.
+
+## Ownership
+
+- Brain may request evidence but maps only logical metadata it actually knows.
+- Sense is the default evidence owner and advances the status monotonically for a given capture attempt: `pending -> processing -> success|failed`. It must retain the same `evidence_id` while status changes.
+- A relay transports the reference unchanged and must not resolve it into a path or URL.
+- Bell stores the latest evidence metadata separately from its immutable Event. Evidence failure/expiry never changes Alert ack/close state.
+
+## Compatibility and rollback
+
+v1 consumers ignore no unknown fields because the v1 schema is closed. Additive fields therefore require a new schema revision that producers enable only after consumers accept it. Changed meaning, removed fields, or new required fields require `/v2`. Rollback disables the new producer and continues resolving stored v1 references; it never deletes Event, Receipt, Outbox, or evidence audit facts.
+
+Run the standalone contract check from the repository root:

+python contracts/tests/evidence-v1/test_contract.py

+# Brain → Sense 运行与健康状态契约 v1
+
+本目录是 Brain 运行状态到 Sense 运维投影的版本化事实源。Brain 只发布脱敏状态事实；Sense 不读取 Brain 的缓存、数据库或内部运行对象，也不能借此契约执行远程命令。
+
+## 消息与时间语义
+
+- `schema_version` 固定为 `yovision.runtime-status/v1`。生产者必须先通过 `runtime-status.schema.json` 再发布。
+- `status_id` 是消息幂等键；`sequence` 在单个 `brain_instance_ref` 内单调递增。重复消息可忽略；小于当前已保存 sequence 的消息不得覆盖投影。
+- `observed_at` 是 Brain 完成该次观测的 UTC RFC 3339 时间，不是 Sense 的接收时间。允许最大 30 秒未来时钟偏差；超过时拒绝该消息，并保留最后已知投影。
+- Brain 的推荐发布周期是 30 秒。Sense 以 `evaluation_time - observed_at > 90 秒` 推导 `stale`；恰好 90 秒仍为 fresh。`stale` 和 `offline` 都是 Sense 的传输/时间投影，不是 Brain 写入的运行状态。
+- 未收到任何有效状态时显示 `not_received`；传输断开但最后状态未过期时显示 `offline_fresh`；传输断开或无新消息且超过 90 秒时显示 `offline_stale` / `stale`，同时保留最后已知状态及其观测时间。
+
+## 状态机
+
+Brain 报告的 `runtime.state` 和每个输入的 `state` 使用同一枚举：
+
+| 状态 | 含义 | 允许的下一状态 |
+|---|---|---|
+| `unconfigured` | 尚无可运行配置 | `starting`, `stopped` |
+| `starting` | 已接受启动，资源准备中 | `running`, `degraded`, `failed`, `stopped` |
+| `running` | 正常提供推理 | `degraded`, `failed`, `stopped` |
+| `degraded` | 仍提供有限服务 | `running`, `failed`, `stopped` |
+| `failed` | 无法继续提供服务 | `starting`, `stopped` |
+| `stopped` | 已有序停止 | `starting`, `unconfigured` |
+
+首次有效消息可为任一状态；Sense 只校验同实例连续消息的迁移。`stale`、`offline_*` 不参与 Brain 状态迁移。恢复连接后，只有 schema、时间、sequence 和状态迁移均有效的新消息才能更新投影。
+
+## 配置流与 revision
+
+`configurations` 按 #148 的配置流报告，可以为空，也可以包含多个配置。每项 `config_id` 必须唯一，并与 `yovision.source-config/v1` 的 `config_id` 一致；重复 ID 使整条状态无效，不能覆盖最后已知投影。`applied_revision` 是 Brain 对该配置流已实际应用的 integer revision。Sense 必须逐个 `config_id` 与自己已投递的期望 revision 比较：相等为 synchronized，不相等为 mismatch；Sense 的期望 revision 不进入本消息，避免产生第二事实源。
+
+- `not_configured`：尚未应用该配置，revision 必须为 null。
+- `applying`：正在应用；revision 为 null 或仍在运行的上一个 revision。
+- `applied`：应用成功，revision 必须是大于等于 1 的整数。
+- `rejected`：本次应用被拒绝；revision 为 null 或最后成功 revision，且必须带稳定错误码。
+
+## 兼容与回退
+
+- v1 字段语义冻结，未知字段被拒绝。新增可选字段或错误码前必须更新本契约及双方测试；改变字段语义或删除字段发布新主版本。
+- 消费者必须按 `schema_version` 先分派到对应版本验证器。未知主版本停止摄取并记录 `UNSUPPORTED_SCHEMA_VERSION`，不得清空或覆盖最后已知投影。
+- 回退时 Sense 停止摄取新版本，继续使用上一冻结版本的 adapter 和最后已知投影。回退不触发 Brain 重启或运行态修改。
+
+## 安全边界
+
+只允许 Schema 列出的字段。逻辑引用不允许 `/` 或 `\\`，因此不能携带绝对路径。消息不得包含凭据/token、堆栈、内部路径、用户会话、客户视频/图像、人脸信息或业务 Alert。结构化错误只传稳定错误码，不传自由文本错误详情。
+
+错误码、映射责任和可复制验证分别见 `error-codes.md`、`mapping.md` 与 `../../tests/runtime-status-v1/README.md`。

+# v1 稳定错误码
+
+生产者可以发布以下稳定错误码。消费者遇到符合格式但尚未认识的 v1 错误码时显示“未识别的远端错误”，保留原始代码用于排障，不把它转换成业务 Alert。
+
+| 错误码 | 责任域 | 含义 |
+|---|---|---|
+| `CONFIG_INVALID` | 配置 | 配置结构或值无效 |
+| `CONFIG_REVISION_UNAVAILABLE` | 配置 | 指定 revision 无法取得 |
+| `INPUT_UNREACHABLE` | 输入 | 逻辑输入暂时不可达 |
+| `INPUT_DECODE_FAILED` | 输入 | 输入解码失败 |
+| `MODEL_LOAD_FAILED` | 模型 | 模型载入失败 |
+| `INFERENCE_FAILED` | 推理 | 推理管线失败 |
+| `RESOURCE_PRESSURE` | 运行 | 资源压力导致降级 |
+| `INTERNAL_COMPONENT_FAILED` | 运行 | 内部组件失败；不随消息暴露组件路径或堆栈 |
+
+`UNSUPPORTED_SCHEMA_VERSION`、`FUTURE_OBSERVATION`、`OUT_OF_ORDER_STATUS` 与 `INVALID_STATUS_TRANSITION` 是 Sense adapter 的本地摄取错误，不由 Brain 发布。

+- Brain：对所有发布消息执行 Schema 校验；覆盖各运行状态、配置应用结果、降级/失败以及敏感字段拒绝。
+- Sense：使用同一有效/无效样例；覆盖版本分派、幂等与倒序、30 秒未来偏差、90 秒陈旧边界、状态迁移、offline/recovery、revision mismatch 及回退不覆盖最后投影。
+- 协调契约：`contracts/tests/runtime-status-v1/test_contract.py` 是双方最小共同测试。产品 adapter 仍需在各自工单中增加本地模型映射测试。

+# Sense → Brain 媒体源与区域规则配置契约 v1
+
+`yovision.source-config/v1` 是 Sense 发布、Brain 消费的完整配置快照。它只携带稳定逻辑标识、无凭据媒体引用、Profile 规格、归一化规则及完整性摘要，不暴露 Sense 数据库模型或 Brain 内部配置模型。
+
+本版本选择 JSON Schema，而不是 OpenAPI：快照可经文件、消息或后续 connector 传输，工单 #148 不定义 HTTP 端点。后续 connector 若提供 HTTP API，应引用本 Schema，不复制字段定义。
+
+## 文件
+
+- `source-config.schema.json`：Draft 2020-12 JSON Schema。
+- `examples/valid/`：可接受的 active 与待重校准快照。
+- `examples/invalid/`：必须安全拒绝的版本、秘密、路径、坐标和绑定错误。
+- `compatibility.md`：版本、兼容周期、迁移和回退规则。
+- `mapper-fields.md`：Sense 生产者与 Brain 消费者字段映射和测试责任。
+
+## 消费规则
+
+1. 先按 JSON Schema 校验，再执行跨字段语义校验。
+2. `schema_version` 必须精确等于 `yovision.source-config/v1`；未知主版本不得降级猜测。
+3. `rule_set.profile_binding` 必须与 `profile.id/width/height` 完全一致。
+4. `rule_set.state != active` 时不得运行任何规则；`recalibration_required` 表示 Profile 规格变化后需重新标定。
+5. `areas` 与 `directional_lines` 的 `id` 在同一快照内必须全局唯一；多边形必须非退化，线段起终点不得相同。
+6. `effective_at` 不得早于 `published_at`。
+7. `integrity.value` 是移除顶层 `integrity` 后，对 RFC 8785 JCS 规范化 JSON 字节计算的 SHA-256 小写十六进制摘要。生产消费者应使用合规 JCS 实现；仓库样例只使用 JCS 简单类型子集。
+
+`media.ref` 是 connector 解析的无凭据不透明引用，固定以 `media:` 开头。它不能包含 URI authority、用户名、密码、查询参数、fragment、Windows 盘符或文件系统路径。RTSP 凭据交换与机器身份不属于本契约。
+
+## 可复制验证
+
+从仓库根目录运行：
+
+```powershell
+& contracts\tests\source-config-v1\run.ps1
+```
+
+脚本在系统临时目录创建隔离虚拟环境、安装固定版本的 Schema 校验器并运行测试，不修改产品目录。测试结束后会清理临时环境。

+# v1 兼容、迁移与回退
+
+## 兼容规则
+
+- v1 发布后只允许在预留的顶层 `extensions` 对象中增加命名空间化、非秘密的可选扩展。消费者必须忽略自己不认识的扩展命名空间，但仍须拒绝当前 Schema 或语义规则标记为非法的输入；发布扩展时应同步生产者/消费者测试。v1 核心对象保持封闭，不能通过新增核心字段规避新主版本。
+- 删除字段、把可选改为必填、收紧已发布取值范围，或改变字段类型、单位、坐标系、Profile 绑定、revision、状态及媒体引用语义，均为破坏性变化，必须发布新主版本目录和新的 `schema_version` 值。
+- 未知主版本必须安全拒绝并保留最后一个已验证配置。不得把未知版本转换成 v1，也不得继续启用来自未知版本的规则。
+- v1 的坐标始终是相对于 `profile.width × profile.height` 图像平面的 0–1 归一化坐标；原点在左上，x 向右、y 向下。该语义不得在 v1 内改变。
+
+## revision 与生效
+
+- `(config_id, revision)` 唯一标识一个不可变快照；同一 `config_id` 的新发布必须使用严格递增的 `revision`。
+- 消费者仅在 Schema、语义和完整性均通过后，按 `effective_at` 原子切换整个快照。重复收到同一 revision 应幂等处理；更小 revision 应拒绝为陈旧配置。
+- Profile ID、分辨率或编码变化时，生产者必须发布新 revision。已有几何尚未按新 Profile 校准时，必须设置 `rule_set.state = recalibration_required`；消费者不得启用其中规则。
+- 新 revision 校验失败或未到生效时间时，消费者保留上一份已验证且仍有效的 active revision。
+
+## 支持周期
+
+- 发布新主版本后，Sense 生产者与 Brain 消费者至少并行支持上一主版本一个正式发布周期，且不少于 90 天；具体停止日期必须在新版本协调工单中冻结。
+- 并行期内生产者按目标消费者能力选择版本，不得把两个主版本字段混在同一快照。
+
+## 回退
+
+1. 停止分发有问题的新主版本或新 revision。
+2. 重新发布上一主版本的最后一个已验证快照；若仍为同一 `config_id`，必须使用该主版本下新的、更大 revision，不能覆盖历史 revision。
+3. Brain 通过完整 Schema、语义和摘要校验后原子切回；切换前继续使用最后一个有效快照，或在没有有效快照时保持规则停用。
+4. 记录失败版本和拒绝原因，但不得记录媒体凭据或完整客户配置。
+
+样例 `examples/valid/recalibration-required.json` 展示 Profile 变化后的安全停用状态。回退不修改已发布 v1 字段语义，也不要求读取 Sense 数据库。

+mapper 必须创建新的契约 DTO，不得直接序列化 Sense GORM 实体，也不得让 Brain 把共享快照当作 `brain.internal.input/v1`。
+
+| 契约字段 | Sense 生产来源/规则 | Brain 消费目标/规则 |
+|---|---|---|
+| `schema_version` | 常量 `yovision.source-config/v1` | 在任何映射前精确校验；未知主版本拒绝 |
+| `config_id` | 新的稳定配置聚合 ID；不是数据库行 ID 语义 | 作为配置流逻辑 ID，不解释为 Brain 内部对象 ID |
+| `revision` | 聚合配置变更时严格递增；不可复用 | 与 `config_id` 共同做幂等、顺序和陈旧检查 |
+| `published_at` / `effective_at` | 发布时写 UTC RFC 3339；生效不得早于发布 | 完整校验后按生效时间原子切换 |
+| `site.id` | 对外稳定站点引用；不得映射客户名或数据库主键语义 | 仅作租户隔离后的逻辑关联；v1 不提供用户身份 |
+| `logical_device.id` | `area.Definition.DeviceID` / `media.Route.DeviceID` 经稳定外部 ID mapper | 映射到 `BrainInputConfig.logical_device_id` |
+| `profile.id` | `area.Definition.ProfileToken` 与 `media.Route.ProfileToken` 经稳定 Profile ID mapper | 映射到 `BrainInputConfig.profile.profile_id` |
+| `profile.width/height/encoding` | `area.Definition.ProfileWidth/ProfileHeight/ProfileEncoding`；必须与当前媒体 Profile 一致 | 映射到规则 `RuleSet` 的 Profile 绑定；不一致拒绝 |
+| `profile.frame_rate` | Sense 已验证 Profile 的帧率快照 | 映射到 `BrainInputConfig.profile.fps` |
+| `media.ref` | 由 `media.Route.ID/Path` 生成 `media:<opaque-resource>`；禁止读取或拼入 `admissionProfile.StreamURI` 及凭据 | 交给后续 connector 解析；不得当作 RTSP URL 或本地路径 |
+| `media.transport` | 当前固定 `rtsp`，仅描述媒体传输类别 | 选择后续 connector/decode adapter；不含认证信息 |
+| `rule_set.version` | 由一组 `area.Version` 聚合成稳定规则集版本 | 映射到 Brain `RuleSet.version` |
+| `rule_set.state` | `NeedsRecalibration=true` → `recalibration_required`；整体禁用 → `disabled`；否则 `active` | 只有 `active` 可构建并启用规则引擎 |

+| `integrity` | 对移除 `integrity` 的 JCS 快照计算 SHA-256 | 映射前重算并常量时间比较；失败保留上一有效 revision |
+
+## 测试责任
+
+- Sense 生产者契约测试：从设备、媒体 Route、Profile 与区域版本 fixture 生成快照；断言字段映射、revision 递增、Profile 变化触发新 revision/待重校准、无秘密媒体引用、Schema/语义/摘要通过。
+- Brain 消费者契约测试：加载本目录有效与无效样例；断言版本拒绝、幂等/陈旧处理、Profile 绑定、坐标、规则 ID、状态门禁和摘要；再映射为 Brain 内部配置，证明共享 `schema_version` 不等于 `brain.internal.input/v1`。
+- 协调契约测试（本工单）：校验所有样例、秘密字段/URL/本地路径拒绝、跨字段语义和摘要。产品 adapter 测试在后续 connector 工单实施。
+
+Sense 与 Brain 各自可增加内部字段，但不得将数据库主键、用户表、JWT、Cookie、摄像头凭据、客户内部路径或内部模型直接扩展进本契约。

+
+从仓库根目录运行：
+
+```powershell
+python -m unittest discover -s contracts/tests/runtime-status-v1 -p "test_*.py" -v
+```
+
+测试只使用 Python 标准库，不安装依赖、不访问网络。它对冻结 Schema 的已用关键字执行验证，并覆盖状态迁移、时间/陈旧边界、offline/recovery、空/多配置流、四种配置应用状态、重复 `config_id`、integer revision mismatch、未知主版本、倒序消息、回退保留和敏感字段拒绝。产品 adapter 还需在各自工单中运行本地模型映射测试。

+## Sense 内部 Outbox 业务规则
+
+- 领域记录与 outbox 必须在同一 PostgreSQL 事务中提交；任一写入失败时两者一起回滚。
+- 幂等键在消息表唯一，成功后还保留永久投递收据；重试和人工恢复沿用原业务记录与幂等键。
+- worker 只能领取到期的 pending/retry 或租约已过期的 processing 记录；同一记录不能被两个 worker 同时成功领取。
+- 失败保留脱敏错误与尝试历史，按退避等待；达到最大次数进入 dead。人工重新排队必须填写原因并记录操作者，不删除历史。
+- implementation_operator、site_admin、viewer 可查看；只有 implementation_operator、site_admin 可重新排队。
+- 未配置外部 connector 时保留内部记录且不阻断 Sense 核心功能。测试 sink 在 prod/production 模式禁止启用。
+- 管理 API 不返回内部 payload、外部凭据或机器身份；Brain/Bell 正式协议属于后续协调工单。

+## Sense 运维告警规则
+
+- 六类运维告警固定为：设备/边缘节点离线、设备认证失败、设备时间漂移、媒体状态对账失败、媒体分片异常、控制隧道异常。
+- 每个“告警类型 + 对象类型 + 对象 ID”只有一条记录；同一源版本重复刷新不增加发现次数，也不产生第二条活动告警。恢复后再次异常复用原记录、递增处理周期并保留全部历史。
+- 状态为 `unacknowledged`（待确认）、`acknowledged`（已确认）、`recovering`（恢复观察）、`recovered`（已恢复）。人工确认只表示已接手，不表示故障恢复。
+- 健康事实恢复后先进入固定 5 分钟观察窗口；只有 `recovering` 且观察窗口结束后才能人工确认恢复。观察期再次异常返回原处理状态并追加恢复失败历史。
+- 确认和恢复都要求 6–256 字符原因、当前版本和允许的状态；旧版本或错误状态返回冲突。所有动作写入独立流转历史和 GoAdmin 操作审计。
+- 运维告警永远设置为 Sense 内部运维记录，不创建本地安全事件或 Bell Alert，不进入跨项目 Outbox，也不实现通知升级。
+<!-- sense-ops-alerts:end -->
+
+<!-- sense-brain-contracts-v1:start -->
+## Sense↔Brain 配置与状态规则
+
+- **配置流**：由稳定 `config_id` 和严格递增的正整数 `revision` 标识；revision 不得复用或倒退。
+- **无凭据媒体引用**：`media.ref` 是由后续 connector 解析的不透明逻辑引用，不是 RTSP URL、本机路径或数据库主键。
+- **Profile 绑定**：规则集必须与 Profile ID、宽高一致；Profile 变化必须形成新 revision，并在需要时标记 `recalibration_required`，旧几何不得静默重投影。
+- **规则坐标**：区域与方向线使用 0–1 归一化坐标，规则 ID 在同一规则集内唯一；退化多边形和重合线端点无效。
+- **完整性**：源配置对移除 `integrity` 后的 JCS 表示计算 SHA-256；校验失败保留上一有效 revision。
+- **配置应用状态**：Brain 在 `configurations[]` 中按 `config_id` 报告 `not_configured/applying/applied/rejected` 与实际 `applied_revision`；同一消息重复 ID 整条拒绝。
+- **状态时序**：Brain 实例 sequence 单调递增；Sense 拒绝倒序消息。观测时间超过约定 90 秒时由 Sense 标记陈旧，不用未知值覆盖最后已知投影。
+- **状态边界**：运行/健康错误只形成 Sense 运维投影，不是业务 Event 或 Bell Alert；不得包含用户会话、凭据、内部路径或客户视频。
+- **版本兼容**：v1 只接受已冻结语义；破坏性字段或语义变化发布新主版本。未知主版本停止摄取并保留上一有效事实。
+<!-- sense-brain-contracts-v1:end -->
+
+<!-- standard-event-evidence-v1:start -->
+## 标准事件、证据和幂等规则
+
+- **标准 Event**：匿名、不可变的跨产品安全事实，不是 Bell Alert，也不携带处置或通知状态。
+- **原始生产者**：`producer_id` 始终标识最初产生事件的 Brain 或 Sense 实例；relay 使用独立传输身份，但不得替换业务生产者。
+- **永久幂等键**：精确 UTF-8 对 `(producer_id, source_event_id)`。重试沿用同一键，不生成新事件。
+- **规范摘要**：完整 Event 使用 RFC 8785 JCS 规范化后计算 SHA-256。同键同摘要为重复成功；同键异摘要为终止性冲突，并追加脱敏审计。
+- **时间格式**：Event v1 使用 UTC RFC 3339、三位毫秒和 `Z`；可选字段缺失时省略，不发送 null。
+- **证据引用**：`evidence_id` 与 `owner_id` 是不透明逻辑引用，不是 URL、文件路径或访问凭据。
+- **证据状态**：`pending → processing → success|failed`。success 要求内容类型和摘要/大小；failed 要求稳定错误码和是否可重试。
+- **降级原则**：证据失败、未知或过期不删除 Event，不自动关闭 Alert，也不伪装成完整成功。
+- **Bell 所有权**：Bell 独占内部 Event/Receipt、规则、Alert、ack、close、通知与用户审计；上游不得写入这些状态。
+- **兼容与回退**：未知主版本终止接收但保留已有事实；破坏性变化发布新主版本。回退停用新生产者版本，不删除 Outbox、Receipt、Event 或审计。

 页面“运行异常”表示最近一次 Control API 探测失败；“状态已陈旧”表示运行循环已超过 30 秒没有更新探测结果。故障时先在详情定位设备/Profile/路径，不要手工改数据库归属。迁移预检不会执行迁移；任何实际跨分片迁移都必须另建高风险工单和回退方案。

+
+升级后应执行包含 `2026082815000_outbox.go` 的数据库迁移。看不到“可靠投递”菜单时，先确认迁移成功，再重新登录或刷新动态菜单。页面提供等待投递、重试、处理中/租约和死信数量；未配置正式 connector 时队列保留，不影响 Sense 设备接入、实时监看和其他核心能力。
+
+积压时先查看状态、可用时间、租约、尝试次数和最近脱敏错误。processing 长时间不恢复时检查 worker 是否仍运行、数据库时间与租约是否过期；不要手工清空租约或删除消息。dead 只能由 implementation_operator 或 site_admin 在排除根因后填写恢复原因重新排队，原业务记录、幂等键和失败历史必须保留。
+
+日志、页面和 API 不得输出内部 payload、外部凭据或机器身份。production 配置不得启用测试 sink。正式 Brain/Bell connector、机器身份、共享 schema 和跨项目 E2E 必须通过后续协调工单交付；停用 relay 可以作为回退，但不得删除未投递记录或永久幂等收据。

+## Sense 运维告警运行与排错
+
+升级后必须执行包含 `2026082816000_ops_alert.go` 的数据库迁移。看不到“运维告警”菜单时，先确认迁移成功，再重新登录或刷新动态菜单。viewer 只能查看列表和详情；implementation_operator、site_admin 可使用“刷新状态”、确认和恢复。
+
+“刷新状态”只读取 Sense 数据库中已有的设备接入、媒体路由、媒体分片和边缘节点健康投影。没有对应健康投影时不会伪造演示告警；先检查上游模块是否已完成探测或心跳入库。分片超过 30 秒没有探测、节点超过 90 秒没有心跳会被判定异常。
+
+确认后仍显示活动告警是正常行为：确认只代表有人处理。源状态健康后进入“恢复观察”，稳定满 5 分钟才能确认恢复；期间复发会返回待确认或已确认。恢复操作被拒绝时先刷新列表，检查健康状态、观察起始时间和页面版本，不要手工改表或删除历史。
+
+运维告警排错不得粘贴设备地址、Stream URI、摄像头凭据、JWT、Cookie 或数据库连接。需要回退时可停止使用刷新/处置入口，但不得删除 `sense_ops_alerts` 或 `sense_ops_alert_transitions` 历史；规则语义变化必须另建工单。

+## Sense↔Brain 契约部署边界
+
+`yovision.source-config/v1` 与 `yovision.runtime-status/v1` 已冻结，但当前没有因此新增监听端口、服务进程、机器凭据或根级编排。#148/#149 只交付 `contracts/**` Schema、样例、兼容说明和契约测试；实际 Sense↔Brain 传输、认证、超时、退避、重启恢复及配置/状态 adapter 由后续 #151、#152 实现和验收。
+
+因此现阶段部署仍按 Sense、Brain 各自独立入口进行，不得手工共享数据库、用户 JWT/Cookie、摄像头凭据、文件目录或临时 JSON 字段来提前打通。需要停用或回退时保持两端独立运行，并保留上一已确认的配置与最后已知状态；未知协议主版本必须停止摄取而不是覆盖投影。
