+# AIOS Silent Release Controller Design Report
+
+状态：隔离分支实现；生产 mutation 禁止
+目标：自动准备 → 自动验证 → 单次 Owner 签名授权 → 分控制器自动执行与验收
+
+## 1. 当前痛点
+
+现有流程需要多轮人工传递 commit、tree、artifact、manifest、测试、canary、drop-in
+和回滚证据。证据在不同消息里重复抄写，容易出现：
+
+- 构建后 artifact、manifest 或 policy 已变化，但旧批准仍被使用；
+- Git、Gitea、systemd 与回滚结果由人工拼接，缺少同一一致性快照；
+- runtime switch、tag、Baseline、Registry 的授权边界不清；
+- 重启后只剩工作树内临时 JSON，无法可靠恢复；
+- approval replay、并发 writer、key revoke 和 secret inheritance 缺少统一防线。
+
+## 2. 新架构
+
+```text
+Build / Test / Canary
+        |
+        v
+ReleaseCandidate + DeploymentPlan
+        |
+        v
+ReleaseAcceptanceEngine

+                BaselineRegistryFinalizeController
+
+Durable ReleaseSagaStore + CapabilityLedger + Event Journal
+贯穿三个控制器；控制器互相不拥有对方的 mutation API。
+```
+
+一次 Owner 批准是同一个不可变 release plan 的签名，不是一个万能执行入口。三个 capability
+分别消费、分别留痕、分别幂等恢复。`force_push`、`tag_rewrite`、`direct_main_push`
+永远不是可签发 capability。
+
+## 3. 状态机
+
+```text
+PREPARING
+  -> VERIFYING
+  -> READY_FOR_APPROVAL
+  -> APPROVED
+  -> PRE_SWITCH_REVALIDATING
+  -> SWITCH_PENDING
+  -> SWITCHED
+  -> RUNTIME_VERIFYING
+  -> TAG_PENDING
+  -> TAG_VERIFIED
+  -> BASELINE_REGISTRY_PENDING
+  -> COMPLETED
+
+任一可恢复故障 -> RECONCILIATION_REQUIRED
+对象冲突       -> MANUAL_OWNER_REVIEW_REQUIRED
+切换后失败     -> ROLLBACK_PENDING -> ROLLED_BACK
+```
+
+状态快照使用 revision compare-and-set；事件同时写入 append-only journal。writer 崩溃后根据
+状态确定唯一恢复动作。并发控制器中只有一个 CAS winner。
+
+## 4. 数据模型
+
+### ReleaseCandidate
+
+```text
+candidate_id
+source_commit
+tree_oid
+artifact_sha256
+manifest_sha256
+tests
+canary
+rollback_ready
+git_consistency
+gitea_consistency
+approval_state
+```
+
+### DeploymentPlan
+
+```text
+service
+release_path / release_root
+dropin_path / dropin_sha256
+rollback_path / rollback_sha256
+source_commit
+artifact_sha256
+manifest_sha256
+policy_sha256
+health_contract
+sha256
+```
+
+### SignedReleasePlanApproval
+
+```text
+release_plan_id
+candidate_id
+source_commit
+tree_oid
+artifact_sha256
+manifest_sha256
+deployment_plan_sha256
+policy_sha256
+approval_plan_id
+evidence_closure_oid
+owner_approval_record_oid
+capabilities
+expires_at
+nonce
+key_id
+signature
+fingerprint
+```
+
+签名内容使用 canonical JSON，`signature` 不参与被签名字段。验证包括 Ed25519 签名、过期时间、
+公钥状态、approval revoke、candidate/plan/policy 逐字段绑定和 capability allowlist。
+
+## 5. API
+
+```text
+POST /createReleaseCandidate
+GET  /getReleaseCandidate?candidate_id=...
+GET  /getApprovalEnvelope?candidate_id=...
+POST /submitOwnerApproval
+POST /startDeployment
+GET  /getReleaseSaga?candidate_id=...
+```
+
+写接口要求 Bearer scope。`AIOS_SILENT_RELEASE_EXECUTION_ENABLED=false` 是默认值；此时可以
+持久化 candidate、生成 approval envelope、保存经验证的 Owner approval 和读取 Saga，
+但 `/startDeployment` 只返回 `SHADOW_MODE` 与空 `side_effects`。
+
+## 6. PreSwitchValidator
+
+切换前重新收集并比较：
+
+- source commit 与 tree；
+- artifact、manifest、policy 和 deployment plan SHA-256；
+- rollback readiness；
+- local、authoritative bare 与 Gitea refs；
+- repository identity；
+- task writer/production writer 边界；
+- health contract。
+
+任一变化都抛出：
+
+```text
+APPROVAL_STALE_REAPPROVAL_REQUIRED
+```
+
+旧批准不会被“最佳努力”继续使用。
+
+## 7. systemd 防线
+
+- service 与 drop-in 均为显式 allowlist；
+- release 与 drop-in resolved path 必须位于 release root 内；
+- 拒绝普通文件被替换为 symlink，拒绝 symlink escape；
+- deployment lock 覆盖 switch、restart 和首次 health check；
+- restart 前后记录 MainPID 与 ActiveEnterTimestampMonotonic；
+- artifact、drop-in、rollback 和 manifest 均按 plan hash 复验；
+- 子进程只接收固定 allowlist 环境，不继承 token、password、credential、askpass、
+  auth socket、`LD_PRELOAD`、`PYTHONPATH` 或数据库连接串。
+
+## 8. TagController 分离
+
+TagController 必须独立完成 approval、execute、verify，并留下：
+
+```text
+evidence_closure_oid
+approval_plan_id
+repository_identity
+remote_tag_oid
+remote_peeled_target_oid
+gitea_api_tag_oid
+gitea_listing_visible
+```
+
+同名 tag 的 tag OID 或 peeled target 不同，进入
+`MANUAL_OWNER_REVIEW_REQUIRED`；自动流程不 push、不删除、不重写、不 force push。
+
+## 9. Baseline / Registry 门禁
+
+只有以下全部一致时，`baseline_registry_finalize` capability 才能完成：
+
+```text
+Registry = Baseline = remote tag = Gitea API = expected target
+```
+
+UNKNOWN、API 不可达、repository identity 不符或 listing 不可见均 fail closed。
+
+## 10. Policy as Code
+
+```text
+automatic:
+  build, test, artifact, canary, evidence
+
+owner:
+  signed_release_plan
+
+capabilities:
+  runtime_switch
+  tag_publish
+  baseline_registry_finalize
+
+forbidden:
+  force_push
+  tag_rewrite
+  direct_main_push
+  baseline_mutation
+  registry_mutation
+```
+
+最后两个 forbidden 项指“脱离受治理 finalize controller 的直接 mutation”。
+
+## 11. Security model
+
+- Ed25519 公钥 ring 支持 rotation 和 revoke，私钥不进入 runtime；
+- approval plan 可撤销，过期、未知 key、错误签名均 fail closed；
+- nonce 与 capability operation 持久化，重复相同请求幂等，不同 fingerprint 重放拒绝；
+- Saga snapshot 原子写、journal append-only、CAS 防并发 writer；
+- credential 只通过受控 reference 使用，不进入 Git、API 响应或异常；
+- 子进程环境从空集合构建，不复制 `os.environ`；
+- Shadow 模式默认开启，execution adapter 缺失时不能降级执行；
+- runtime、tag、Baseline/Registry 分属三个能力最小化控制器。
+
+## 12. Migration plan
+
+1. Shadow：生成 candidate、plan、acceptance、approval package，仅比较现有人工结果。
+2. Signed approval：接入 Owner 公钥 ring、撤销源和审计 record；仍不接生产 executor。
+3. Canary execution：使用非生产 service/release root 验证锁、PID、health、崩溃恢复和回滚。
+4. Controlled production switch：另行 Owner 授权启用 execution flag，只开放 runtime capability。
+5. Tag/finalize：分别完成 Gitea 与 Registry/Baseline 生产验收后再启用对应 capability。
+
+每个阶段均可退回上一个阶段；不开启下一能力不会影响已经启用的控制器。
+
+## 13. Rollback plan
+
+- switch 前保存旧 symlink target、PID、启动时间、artifact 与 plan fingerprint；
+- restart 或 health 任一失败进入 `ROLLBACK_PENDING`；
+- 原子恢复旧 target，只 restart 指定 allowlist service；
+- 重新验证旧 runtime commit、writer=false 与 repository identity；
+- 成功进入 `ROLLED_BACK`，失败进入 `MANUAL_OWNER_REVIEW_REQUIRED`；
+- rollback 不修改 Git main、production tag、Baseline 或 Registry；
+- 保留脱敏 journal、approval fingerprint 和失败证据。
+
+## 14. 测试与外部依赖边界
+
+自动测试覆盖签名伪造、字段篡改、过期/revoke/key rotation、nonce replay、CAS race、
+崩溃恢复、artifact/policy/plan mutation、tag conflict、secret leakage、runtime without
+`.git`、rollback 和 shadow no-side-effects。
+
+本隔离实现不创建生产 KMS/key、不安装 systemd unit、不部署 Action runtime、不创建 tag，
+也不修改 Baseline/Registry。上述动作必须在单独生产批准中执行。

+# AIOS Silent Release Execution Readiness
+
+## Scope and stop point
+
+This change makes the controller execution-ready while deploying only a
+localhost-bound Shadow control plane. Both production gates remain false:
+
+```text
+AIOS_GITOPS_WRITES_ENABLED=false
+AIOS_SILENT_RELEASE_EXECUTION_ENABLED=false
+```
+
+Shadow completion is evidence preparation, not a production release. It cannot
+write a production tag, switch a business runtime, or mutate Baseline/Registry.
+
+## Recovery state machine
+
+Every expired or `FAILED_RECOVERABLE` capability requires fresh, operation-bound
+probe evidence before another adapter may run:
+
+```text
+NOT_APPLIED       -> one new exclusive claim may retry
+APPLIED_VERIFIED  -> mark COMPLETED without adapter replay
+INDETERMINATE     -> RECONCILIATION_REQUIRED; no automatic writes
+CONFLICT          -> MANUAL_OWNER_REVIEW_REQUIRED; no automatic writes
+```
+
+Probe evidence binds the immutable operation digest, is freshness checked, and
+is appended to a separate SHA-256 hash-chained journal. Completion still
+requires the active claim ID. File locks and leases ensure that concurrent
+recovery workers cannot execute the same adapter.
+
+`TAG_PENDING` uses independent remote ref, annotated object, peeled target,
+Gitea API, Gitea listing, and repository identity evidence. Exact absence may
+roll back a switched runtime. Exact publication continues to finalization.
+Unavailable/divergent evidence stops at reconciliation; a different OID or
+target stops for Owner review. No branch can force, delete, or rewrite a tag.
+
+## Trusted build and approval
+
+Callers submit only an event ID and exact source commit. Test, canary, artifact,
+manifest, rollback, secret scan, Git and Gitea evidence are generated by the
+trusted builder. The builder emits an Ed25519 attestation binding:
+
+- builder attestation/key IDs;
+- source commit and tree OID;
+- artifact, manifest and package-closure SHA-256;
+- test and canary evidence SHA-256;
+- issuance time and signature.
+
+The controller contains only trusted public keys. Production signing is exposed
+through a KMS/HSM/secret-manager adapter; a local private-key adapter is marked
+test-only and is used only for ephemeral Shadow acceptance.
+
+Owner approvals are immutable, time-bounded, revocable, trust-domain bound, and
+single-use per capability ledger. If the production approval backend reference
+is absent, production execution is unavailable while Shadow remains available.
+Caller-supplied `owner_id` is never a fallback.
+
+## Persistent controller and API
+
+`aios-silent-release-controller.service` runs independently from the business
+GitOps API. It uses a single leader lock, durable intents/candidates/Sagas,
+startup journal verification, idempotent main events, one notification record,
+and recovery reporting. The final deployed service is report-only Shadow mode.
+
+The Action contract exposes:
+
+- `createReleaseIntent`
+- `getReleaseCandidate`
+- `getReleasePlan`
+- `getReleaseAcceptance`
+- `submitSignedApproval`
+- `getReleaseSaga`
+- `getCapabilityStatus`
+- `startDeployment`
+- `getRecoveryStatus`
+
+Every Shadow response declares `execution_enabled=false`, `shadow_mode=true`
+and `side_effects_executed=false`. `startDeployment` returns a simulated
+`SHADOW_COMPLETED` result and never claims production capabilities.
+
+## Migration and rollback
+
+1. Merge through a governed pull request.
+2. Build from a clean detached worktree at the exact merge commit.
+3. Verify artifact, manifest, package closure, tests, live fixture, no-.git
+   canary, rollback archive and secret scan.
+4. Install a versioned Shadow release without changing the business runtime.
+5. Start the separate localhost-only controller with both gates false.
+6. Run Shadow candidates and freeze production PID/tag/Baseline/Registry hashes.
+7. Remove ephemeral test keys and temporary repositories.
+
+Rollback stops and disables only the Shadow controller and restores/removes its
+versioned `current` link. The existing production API, tag set, Baseline and
+Registry are not involved.
+
+## Future activation envelope
+
+Activation requires a new one-time Owner approval binding the exact controller
+commit, artifact/manifest/policy/unit hashes, trusted key IDs, KMS/secret
+references, release and rollback roots, authoritative Git/repository identity,
+Shadow candidate/evidence IDs, test results, activation plan and rollback plan.
+That approval may only flip
+`AIOS_SILENT_RELEASE_EXECUTION_ENABLED=false` to `true`; each real release still
+requires its own signed ReleasePlan. This change does not request or consume
+that activation approval.

+# Silent Release Controller Production Contract
+
+Status: review-only implementation. Production execution remains disabled.
+
+## Trust boundary
+
+The caller submits only release intent. A configured trusted builder owns ref
+validation, build, tests, artifact and manifest hashing, package closure,
+canary, rollback readiness, Git/Gitea consistency, and secret scanning. Caller
+supplied success evidence is rejected.
+
+The resulting immutable `ReleasePlan` contains deployment, tag, and
+finalization plans. One Ed25519 owner signature binds its SHA-256 digest,
+candidate evidence, policy digest, owner identity, trust domain, validity
+window, evidence lineage, and three narrow capabilities.
+
+## Durable execution
+
+The Saga journal is the source of truth. Every record is sequence-numbered and
+SHA-256 hash-chained from a fixed genesis hash. Snapshots are rebuildable
+caches. Journal corruption, truncation, reordering, missing records, or hash
+mismatch moves the release to `MANUAL_OWNER_REVIEW_REQUIRED`.
+
+Capability execution uses an exclusive, leased claim. A second worker receives
+`BUSY`; an expired claim is not reassigned until a capability-specific
+side-effect probe reports that the operation was not applied. Runtime, tag,
+and finalization remain separately claimed and recoverable.
+
+## Execution order
+
+```text
+APPROVED
+  -> PRE_SWITCH_REVALIDATING
+  -> SWITCH_PENDING
+  -> SWITCHED
+  -> RUNTIME_VERIFYING
+  -> RUNTIME_VERIFIED
+  -> TAG_PENDING
+  -> TAG_VERIFIED
+  -> BASELINE_REGISTRY_PENDING
+  -> COMPLETED
+```
+
+The actual adapter configuration is regenerated before execution and must
+match the signed plan. Trusted allowlists come from controlled policy, not the
+request.
+
+A failure before verified tag publication rolls the runtime back. A failure
+after the exact tag is verified enters `RECONCILIATION_REQUIRED`; the tag is
+never deleted or rewritten. A same-name/different-OID conflict enters
+`MANUAL_OWNER_REVIEW_REQUIRED`. Registry/Baseline finalization requires exact
+remote and Gitea tag proof, and Baseline is recorded last.
+
+## Action and recovery contract
+
+`submitOwnerApproval` verifies and durably stores the signed plan, then moves
+the Saga to `APPROVED`. `startDeployment` loads that durable approval and
+ignores caller-supplied approval content. Enabling execution without the
+trusted builder, verifier, validator, policy, and orchestrator fails during
+service construction.
+
+The recovery worker scans incomplete journals and resumes through the same
+claims and verification gates. It never automatically resumes a manual-review
+Saga. In shadow mode it only reports state and performs no adapter side
+effects.
+
+The deployed Action factory does not enable the legacy caller-evidence path.
+If the trusted builder is absent, candidate creation is rejected even while
+execution remains in shadow mode. The compatibility path exists only through
+the explicit test-only `SilentReleaseActionService.shadow()` constructor.
+
+Finalization is composed from separate `RegistryController` and
+`BaselineController` claims. Registry is verified first and Baseline is the
+last mutation; a retry reuses completed Registry evidence and never moves
+Baseline ahead of tag verification.

+# Gitea Tag Publication Atomicity
+
+Release publication is a fail-closed Saga bound to one immutable governance
+fingerprint:
+
+- `version`
+- `target_oid`
+- `evidence_closure_oid`
+- `approval_plan_id`
+
+The normal progression is:
+
+`PENDING` → `LOCAL_TAG_CREATED` → `REMOTE_PUSH_CONFIRMED` →
+`GITEA_API_CONFIRMED` → `BASELINE_UPDATE_PENDING` → `BASELINE_UPDATED` →
+`PRODUCTION_DEPLOYED`
+
+An unavailable remote uses `REMOTE_PUSH_PENDING` or
+`RECONCILIATION_REQUIRED`. A same-name tag object mismatch, peeled-target
+mismatch, changed governance fingerprint, or immutable deployment-evidence
+conflict enters `MANUAL_OWNER_REVIEW_REQUIRED`. That state blocks automatic
+push and reconciliation; recovery never deletes, rewrites, or force-pushes a
+tag.
+
+## Legacy state migration
+
+Readers normalize the historical `TAG_CREATED_LOCAL` value to
+`LOCAL_TAG_CREATED` in memory. Read-only status responses therefore expose only
+the canonical value. The next governed Saga write persists the canonical name;
+reading legacy state alone does not mutate the tag, Baseline, Registry, or Saga
+file. Any unrecognized persisted state fails closed as
+`RECONCILIATION_REQUIRED`.
+
+`BASELINE_UPDATE_PENDING` is persisted before either `baseline/current.json` or
+`versions/<version>.json` changes. Recovery revalidates the governance
+fingerprint, evidence lineage, remote annotated tag, peeled target, Gitea API,
+listing, and repository identity before idempotently completing matching
+partial records. A different tag or target enters
+`MANUAL_OWNER_REVIEW_REQUIRED`.
+
+## Durable state
+
+Production writers set `AIOS_GITOPS_PUBLICATION_STATE_DIR` to storage outside
+their disposable worktree. Recreating a writer must reuse that directory.
+Worktree JSON is not the authoritative Saga store.
+
+## Deployment gate
+
+`mark_production_deployed` performs fresh Git remote, peeled-target, Gitea ref,
+Gitea tag-object, listing, repository-identity, evidence-lineage, Registry, and
+Baseline checks. Deployment is allowed only when:
+
+`Registry = Baseline = remote tag = Gitea API = expected target`
+
+Deployment evidence must be an immutable `sha256:<64 hex>` or `git:<40 hex>`
+identifier.
+
+## Read-only acceptance
+
+- `getTagPublicationStatus` reads durable Saga state.
+- `getReleaseConsistency` compares every release authority.
+- `runReleaseAcceptance` returns `accepted: true` only for `PASS`.
+
+Unavailable evidence returns `UNKNOWN` with `fail_closed: true`; it is never
+treated as acceptance.
+
+The CLI, HTTP Action, and release script all enter the same publisher core for
+evidence-lineage verification. The release script stages Registry and Baseline
+records only; durable Saga state remains outside Git.

+# Isolated Writer Exact-Path Policy V1
+
+This policy is an additional, service-owned authorization layer for
+`POST /api/commit-file`. It never expands a Token Policy V2 grant.
+
+An atomic write is permitted only when all of the following agree:
+
+1. socket peer, audience, operation, branch, base and exact path in the
+   Token Policy V2 grant;
+2. service audience, repository identity, branch, operation and exact path
+   in `AIOS_GITOPS_PATH_POLICY_FILE`;
+3. lexical path, resolved containment and symlink checks;
+4. the configured content-size and content-profile checks;
+5. operation digest, expected branch HEAD and durable operation ledger.
+
+Any failed layer returns a fail-closed policy error. Coarse `/api/file` and
+`/api/commit` routes remain forbidden.
+
+## File contract
+
+The configured path must be absolute. The parent directory must be
+`root:gitops 0750`; the regular, non-symlink file must be
+`root:gitops 0640`. JSON must use UTF-8 canonical encoding with sorted keys,
+compact separators and one trailing newline. Unknown fields, unsupported
+operations or profiles, duplicate paths, oversized policies and
+group/world-writable files are rejected during Writer startup.
+
+Example:
+
+```json
+{"allowed_branch":"patch/codex-review-test-worker-20260724","allowed_operations":{"commit_file.atomic":{"content_profile":"systemd-codex-review-worker-v1","exact_paths":["deploy/systemd/aios-codex-review-test-worker.service"],"max_content_bytes":32768}},"audience":"aios-codex-review-worker-writer.service","policy_id":"codex-review-worker-path-policy-v1","repository_identity":"aios/aios","schema_version":1}
+```
+
+The SHA-256 of the canonical policy is exposed in the isolated runtime
+status and written to the operation audit record. The request body cannot
+select or override the policy file.
+
+## Content profile
+
+`systemd-codex-review-worker-v1` is an exact, fail-closed unit grammar. The
+only sections are `[Unit]`, `[Service]` and `[Install]`. Each section has a
+directive allowlist; every single-value directive and every repeated
+`Environment`, `ReadOnlyPaths` and `ReadWritePaths` entry must match the
+governed Shadow unit contract exactly.
+
+The profile fixes the Python module
+`task_plane.workers.codex_review_test`, `User=aiman`, `Group=gitops`,
+the controlled `/usr/libexec/aios-codex-review-test-worker/current`
+working directory, all hardening switches and the three permitted
+environment variables. It grants read access only to the authoritative
+bare repository and the versioned worker artifact, and write access only
+to the worker runtime, state and cache directories.
+
+Unknown sections or directives are rejected, including lifecycle hooks,
+credential injection, environment imports, root images, bind mounts,
+capability expansion, devices, sockets and top-level writable paths. The
+parser also rejects duplicate sections, duplicate single-value directives,
+empty resets, continuation lines, CRLF, NUL, non-UTF-8 surrogate content,
+overlong lines and Unicode lookalike directive names. It does not use
+`ConfigParser(strict=False)` or silently merge repeated values.
+
+Production credentials, if later authorized, must be supplied by a
+separately governed deployment drop-in. They are not permitted in the
+source unit or this content profile.
+
+Policy changes require a separate maintenance branch and Owner-reviewed
+ordinary merge commit. A task-scoped Writer must not edit its own policy
+file.

 The obsolete release-plan `DECLARED` rows are not authoritative for this run. The production gate must explicitly select `AIOS-V2R1C2-UNIFIED-PORTAL-TAKEOVER-20260722` and require its three required stages to be `SUCCEEDED`; an unqualified aggregate across stale plan rows fails closed.
 
+## Synthetic WeChat scope
+
+WeChat-facing acceptance for this release used synthetic/mock receipts and transcripts only. It did not impersonate a real user and does not claim a real-user WeChat session. The relevant committed evidence entries are `wechat_simulated_receipts` and `wechat_simulated_transcript`; the production online smoke also records `simulation: true` and `real_user_impersonated: false`.

 ## Rollback rule
 
 If Health, API, UI, Role Matrix, Tenant Isolation, Runtime, or Audit verification fails after the 18920 switch, stop the V2R1C2 production unit and restart the preserved V2R1C1 18920 service. Do not delete or rewrite either release tag or rollback asset.
+
+## Result
+
+The production switch completed at `2026-07-22T01:40:51Z`. Full acceptance and the production online smoke passed, including Health, API, UI, Role Matrix, Tenant Isolation, Runtime, Audit and the selected takeover release gate. The previous `aios-orchestrator-gateway.service` unit, configuration and Release Run backup remain available for rollback.

+# AIOS Task Plane
+
+该模块是与任务发起方、Worker 类型和通知后端解耦的持久化任务控制平面。当前交付仅用于隔离开发与 Shadow 验收；默认 `execution_enabled=false`，不会修改生产、tag、Baseline 或 Registry。
+
+## 架构
+
+- `TaskPlaneService`：统一服务边界和 HTTP 路由。
+- `TaskPlaneStore`：SQLite WAL、revision/CAS、串行事务、租约、hash-chained journal、evidence 和 durable outbox。
+- `WorkerRegistry` / `LeaseManager`：身份绑定、capability、并发额度、心跳、过期探测后恢复。
+- `DelegationEngine`：父子 DAG、全局深度、capability/risk/approval/budget 单调约束和幂等重放。
+- `PolicyEngine`：默认关闭执行；身份、证据、结果摘要和可插拔签名验签均 fail-closed。
+- `WorkerAdapter`：OpenClaw、Codex、Hermes、A2A 和 systemd Worker 的统一契约。默认实现只返回 `SHADOW_VERIFIED`，不执行外部命令。
+- `DurableOutboxDispatcher`：Webhook、NATS JetStream、GPT callback、Dashboard 和 WeChat 的回执式通知接口。没有真实回执时始终保留 `NOT_DELIVERED`。
+
+## 状态与恢复
+
+正常路径为 `CREATED → QUEUED/CLAIMED → RUNNING → VERIFYING/COMPLETED`；失败路径使用 `FAILED_RECOVERABLE`、`FAILED_FINAL`、`CANCELLED` 或 `MANUAL_REVIEW_REQUIRED`。每次状态事件都进入同一事务中的 append-only hash chain。
+
+租约过期不会自动重放副作用。控制平面必须先调用 Worker probe，只有明确确认原执行已停止，才可将 claim 标记为 `EXPIRED` 并把任务转为 `FAILED_RECOVERABLE`。结果必须匹配 task、claim、Worker identity、未过期 lease 和 operation digest；重复结果返回冲突。
+
+## 安全模型
+
+- task/worker/claim/message ID 使用 allowlist pattern，拒绝 URL 编码差异、路径分隔符和控制字符。
+- HTTP body 最大 1 MB，非对象 JSON、异常 Content-Length 和非法参数返回 400/413。
+- 内部异常响应不回显路径、payload 或凭据；默认 HTTP access log 不记录原始 request target。
+- secret-like 字段在 durable task、event、evidence 和 outbox 写入前脱敏。
+- 结果签名存在但没有配置验签器时拒绝；摘要、evidence 或 event 被篡改时验收失败。
+- SQLite 文件创建为 0600；新建状态目录使用 0700。
+
+## 验收
+
+```bash
+PYTHONPATH=active-runtime \
+  bash scripts/task-plane/run_task_plane_acceptance.sh
+
+PYTHONPATH=active-runtime \
+  python3 scripts/task-plane/create_shadow_tasks.py \
+    --database reports/task-plane-shadow.sqlite3 \
+    --report reports/task-plane-shadow.json
+```
+
+上述脚本只使用本地 SQLite 和 Shadow adapter，不触发真实 OpenClaw、Codex、Hermes、微信或生产执行。
