Merge PR #88: successor-aware governed release artifact producer (V2R2C3)

True merge of agent/successor-aware-governed-release-producer-20260916
(tip da0474c) into main 057e915.

Conflict resolution (4 test files):
- tests/task_plane/test_autonomous_next_child.py   -> successor-aware deterministic offline contract
- tests/task_plane/test_legacy_attachment.py       -> _APP_DIR single real app path
- tests/task_plane/test_terminal_proof_importer.py -> explicit purpose on C01 and C06
- tests/test_g7_web_surface_negative.py            -> keep main structure (cosmetic-only change)

Canary V2R2C3-LIVE-BINDING-CONVERGE re-bind: source/tree oid hoisted into
MERGED_SOURCE_OID / MERGED_TREE_OID placeholders (all-zero) pending the
post-merge commit id.

+"""aios_owner_based_executor — Owner 基于授权的可执行 CLI 入口。
+
+把 "owner 基于授权 → Agent 自主完成受治理写链" 从测试/装配层提升为**可直接执行的命令**。
+集成 V2R2C3 现场组合根 `field_governed_writer.py`，装配到生产入口
+`GovernedWriterAutomation.acquire_verified()`。
+
+子命令：
+  register <authorization_ref>  登记一条 Owner 授权到 authority（可 --policy-json 指定，
+                                 默认用内置参考授权物 azn-owner-gw-v1）。
+  acquire <authorization_ref>   装配 FieldGovernedWriterFactory，运行 acquire_verified()，
+                                 输出 GovernedWriterSession JSON。
+
+行为契约：
+- 生产入口唯一授权来源是 authority 已登记的 authorization_ref；未登记即 fail-closed。
+- authority 未装配（--no-authority 或构造时 owner_authority=None）→ AuthorizationDenied。
+- EXPIRED 任务无预签 recovery → OwnerActionRequired（OWNER_BOUNDARY，非自动恢复）。
+- status==error 输出到 stderr，退出码非 0；成功输出会话 JSON，退出码 0。
+- legacy_global_writes_enabled 默认 false = 安全不变式，不是 blocker。
+
+用法示例：
+  python aios_owner_based_executor.py register azn-owner-gw-v1
+  python aios_owner_based_executor.py acquire azn-owner-gw-v1
+  python aios_owner_based_executor.py acquire azn-owner-gw-v1 --branch-mode continue --head-oid <oid>
+  python aios_owner_based_executor.py acquire azn-owner-gw-v1 --task-status EXPIRED   # OwnerBoundary

+"""现场（field）组合根：让"Owner 基于授权"真正可接线、可执行。
+
+本模块是 V2 governed-writer 机制的**现场装配层**，职责：
+- 实现正式的 `OwnerAuthorizationAuthority`：持有 Owner 登记的授权记录
+  （authorization_ref -> OwnerAuthorizationPolicy），`verify()` 解析引用、
+  核验策略、签发 verification receipt；未知引用 / 策略失效一律 fail-closed。
+- 提供 `FieldGovernedWriterFactory`（组合根）：把 7 个协议适配器（signer /
+  execution / principal_issuer / jobs / git / writer_lease / owner_authority）
+  装配到 `GovernedWriterAutomation.acquire_verified()` 生产入口上。
+- 提供默认的生产适配器参考实现（`_DefaultOwnerAuthority`），供现场在真实
+  端点未就绪时先闭环；真实端点就绪后替换对应 adapter 即可，组合根接口不变。
+
+设计原则（与 OWNER_AUTHORIZATION_MODEL.md 的 `aios.owner-authorization.v1` 一致）：
+1. 生产入口唯一授权来源是 Owner 登记的 `authorization_ref`；Agent 本地自造的
+   `OwnerAuthorizationPolicy` 不构成 proof（fail-closed）。
+2. 长期业务授权（Policy）与短时执行凭证（epoch/lease/principal）分离。
+3. `legacy_global_writes_enabled=false` 是安全不变式，不是 governed-writer blocker。
+
+本模块不修改 S6 frozen 9 文件，不触碰 legacy/global 写；只做 governed 写路径的
+现场装配。适配器接口全部复用 `governed_writer_automation.py` 的 Protocol。

+- T2：`app.task_plane.governance_control_kernel` 的冻结控制内核公开面

+T2 里 `ConsistencyBarrier` 就是需求文档中的 "PreflightBarrier"：控制内核的

+
+Windows 说明：控制内核每次操作新建 sqlite 连接且依赖 GC 释放句柄（连接对象与

+
+与 V2 单元测试（test_governed_writer_automation.py，15 项）的区别：这里断言的是
+**真实生产入口** `GovernedWriterAutomation.acquire_verified()` 的端到端行为，符号
+全部从生产模块直接导入并真实执行——Owner 授权经正式 `OwnerAuthorizationAuthority`
+验证后，Agent 在 `legacy_global_writes_enabled=false` 前提下自动走完
+claim → TaskLease → TaskPrincipal → job → live branch CAS → WriterLease。
+
+覆盖 V2 需求书强调的语义（不得因 `AIOS_GITOPS_WRITES_ENABLED=false` 宣布 writer
+blocked）：
+- T2 生产入口：`acquire_verified()` 必须经正式 authority 返回 verification receipt；
+  未配置 authority → fail-closed；未经授权本地 policy 不构成 proof。
+- T3 协议路径：legacy/global writes=false 不阻塞；ambiguous writes_enabled=false
+  被忽略；scope 扩张 fail-closed→Owner；同 scope 过期 epoch 经 signer JIT 重签；
+  QUEUED task 全自动达到 WriterLease；EXPIRED 无预签 recovery→Owner；
+  EXPIRED 有预签 recovery→自动恢复；live branch HEAD 决定 CAS；
+  能力不足阻断 WriterLease；stale manifest 在任何副作用前阻断。
+
+Windows 说明：本文件不使用 `with tempfile.TemporaryDirectory()`，而是
+`tempfile.mkdtemp()` + tearDown 中 `gc.collect()` 再 `rmtree(ignore_errors=True)`，
+规避清理期 WinError 32。
