v2r2c4 S1 successor: land autonomous resume controller/adapter/integration + tests + hardened protocol

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

+"""AIOS-native binding layer for the unattended resume controller.
+
+This module intentionally contains no HTTP client, Unix-socket client, database,
+systemd integration, scheduler loop, secret handling, or privileged identity
+mutation.
+
+It converts existing AIOS authorities into the generic callbacks defined by
+``autonomous_resume_integration``. Field code supplies the current authoritative
+implementations for:
+
+- durable Owner authorization/grant projection;
+- canonical governed-worker activation/status;
+- governed task admission;
+- task/claim/TaskLease/TaskPrincipal/WriterLease/CAS ownership;
+- bounded source-lane execution and integration;
+- Gate0;
+- ReleaseReady/deployability;
+- PromotionController;
+- final production acceptance;
+- mission resume lease/checkpoint/effect reconciliation.
+
+The adapter is deterministic and fail-closed. It never fabricates any credential,
+principal, lease, fence, task, commit, receipt, approval, or deployment result.

+"""Deterministic unattended mission-resume controller for AIOS.
+
+The controller is deliberately small and does not create a second scheduler,
+database, identity system, or release control plane.
+
+It executes exactly one reconciliation/progress cycle per ``run_once`` call.
+An existing AIOS scheduler/timer/worker loop should invoke it periodically.
+
+All consequential effects are delegated through ``AutonomousExecutionPort`` and
+must use the existing AIOS authorities: durable Owner authorization, task
+admission, claim/TaskLease/TaskPrincipal, WriterLease/CAS/fencing, Gate0,
+ReleaseReady, PromotionController and governed rollback.
+
+The controller's responsibilities are limited to:
+- one-winner resume lease acquisition;
+- durable checkpoint progression;
+- bounded retry/backoff;
+- unchanged deterministic blocker suppression;
+- UNKNOWN/ambiguous-effect reconciliation before retry;
+- non-interactive owner-boundary recording;
+- crash-safe phase resumption.
+
+It never manufactures credentials, group membership, principals, leases,
+signatures, branch OIDs, or release receipts.

+- 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。

+# ADR: R2 evidence digests reuse TaskPlane canonical JSON
+
+Status: ACCEPTED FOR R2 REVIEW CANDIDATE
+Date: 2026-09-14
+
+## Context
+
+R1 introduced local sorted/separator JSON encoders in schedulability proof and
+Retry/Toil fingerprint code. Platform Baseline V4 §1.3/§4.4/§12 prohibits new
+parallel canonical encoders unless a scoped ADR proves the existing contract is
+not applicable.
+
+The candidate already carries the established TaskPlane contract:
+
+`app.task_plane.models.canonical_json(value)`
+
+which serializes UTF-8 JSON deterministically with sorted keys and compact
+separators.
+
+## Decision
+
+R2 reuses `task_plane.models.canonical_json` for:
+
+1. schedulability observation/proof digests;
+2. Retry/Toil operation fingerprint payloads.
+
+Retry/Toil adds a domain schema wrapper
+`aios.retry-toil-fingerprint.v1` before hashing so the digest domain is
+separated without inventing a new byte encoder.
+
+No generic canonical platform, second encoder, or new write authority is added.
+
+## Bytes and algorithm
+
+- canonical text producer: `task_plane.models.canonical_json`
+- bytes: UTF-8 encoding of that exact text
+- digest: SHA-256 hex
+- schedulability schema: `aios.schedulability-proof.v2`
+- retry fingerprint schema: `aios.retry-toil-fingerprint.v1`
+
+## Migration / compatibility
+
+These R2 modules are not yet live authorities. Their R1 digests are review
+candidate evidence only and do not require backwards-compatible production
+decoding. Any future persisted proof/fingerprint consumer must bind schema
+version explicitly.
+
+## Guard
+
+R2 tests reject a reintroduction of local `json.dumps(sort_keys=True,
+separators=...)` encoders in the two modules.

+# AIOS Unified Platform Convergence — Architecture Change V2
+
+Status: R2 REVIEW CANDIDATE
+Date: 2026-09-14
+Authority base for rebind: `beabd053961047f170e87e1110f2636dbd50f5fb`
+
+## 1. Purpose
+
+R2 preserves the R1 architectural direction but corrects the eight review
+findings F01–F08. It does not authorize deployment.
+
+The program still has four tracks:
+
+1. existing Identity / Lineage S3;
+2. ANNEX-2.3 R2 Auto-Claim / Execution Integrity;
+3. Platform Generation G0 (WP0a–e/WP1/WP2 only);
+4. governed merge, staging, release and root/program acceptance.
+
+Existing Identity/Lineage mission/root/children remain authoritative and are
+not recreated or redefined by this program.
+
+## 2. Authority split
+
+- Git authority main: `beabd053961047f170e87e1110f2636dbd50f5fb`
+- release-control runtime: `3c320aeb89d9ba8f0ed516abeb57252682b18983`
+- production V2R2C2: `4642b74af62c89a505ae49241e805a5a88ca897f`
+
+A review candidate is not a governed commit. All target preimages must be
+refreshed from live Git authority before submission.
+
+## 3. R2 safety corrections
+
+### 3.1 Caller evidence is fail-closed
+
+`caller_scan v2` separates:
+
+- static source caller evidence;
+- active runtime caller evidence;
+- test-only evidence;
+- opaque/dynamic uncertainty;
+- complete negative evidence.
+
+Static source imports alone do not prove runtime LIVE.
+
+`PROVEN_ORPHAN` requires all of:
+- zero production static caller;
+- zero active systemd/API/scheduler/runtime-loaded caller;
+- relevant runtime host set non-empty and completely scanned;
+- loaded bytes negative proof;
+- systemd/API/scheduler scan coverage;
+- complete observation window;
+- no probe failures/opaque dynamic references;
+- rollback reference;
+- independent acceptance `GO`.
+
+Incomplete negative evidence returns `LIKELY_ORPHAN`; probe failure, opaque
+dynamic import, or unresolved production source caller returns `UNKNOWN`.
+UNKNOWN can never drive Sunset.
+
+### 3.2 Schedulability proof is diagnostic, final claim is authoritative
+
+R2 checks task lifecycle state and treats explicit `max_concurrency=0` as zero.
+Invalid capacity values are structured blockers.
+
+The proof remains non-bearer. Claim has three stages:
+
+1. preflight observation;
+2. claim-time read-only recheck;
+3. existing TaskPlane authority performs `claim_atomically` at the
+   linearization point.
+
+The atomic adapter contract must revalidate task revision/generation/status,
+worker generation/identity/health/capacity, authorization ref/revision,
+scope, dependencies, freeze and conflicting lease inside the same
+authoritative transaction/fenced operation that creates the claim.
+
+The returned receipt must include claim id, lease id, fencing generation and
+receipt revision.
+
+R2 reference tests verify the adapter contract only. They do **not** prove a
+production adapter is atomic; real staging A18–A23 remain mandatory.
+
+### 3.3 Retry Governor is whitelist-only
+
+- UNKNOWN/indeterminate → RECONCILE;
+- governance/dependency boundary → BLOCK;
+- proven success → SUPPRESS/REUSE;
+- unrecognized state → BLOCK;
+- only explicitly executable states may return EXECUTE.
+
+A prior success for the same operation conflicting with a later NOT_APPLIED
+observation must reconcile rather than re-execute.
+
+### 3.4 Canonical bytes are reused
+
+Schedulability and Retry/Toil reuse
+`app.task_plane.models.canonical_json`; no second JSON canonical encoder is
+introduced. See `ADR_CANONICAL_EVIDENCE_DIGEST_V1.md`.
+
+### 3.5 Platform G0 discovery is not G0 acceptance
+
+WP0a–d and WP1 now expose completeness/missing evidence. Lexical/static
+discovery cannot by itself satisfy Generation-G0 Exit.
+
+See `G0_EVIDENCE_COVERAGE_V2.md`.
+
+## 4. Non-circular review/deploy gates
+
+R1's production gate was circular because existing root C06 and Program
+production evidence could be required before production itself.
+
+R2 replaces it with:
+
+```text
+REVIEW_READY
+  ↓
+STAGING_ACTIVATION_READY
+  ↓
+STAGING_ACCEPTED
+  ↓
+PRODUCTION_ELIGIBLE
+  ↓
+PRODUCTION_ACCEPTED
+  ↓
+PROGRAM_COMPLETE
+```
+
+### REVIEW_READY
+
+Requires:
+- live authority rebind + exact preimages;
+- ChangeEnvelope complete;
+- complete affected repository regression;
+- independent review GO.
+
+### STAGING_ACTIVATION_READY
+
+Requires:
+- governed commit + authority readback;
+- bounded staging activation scope;
+- rollback/recovery plan ready;
+- pre-activation lab/contract evidence.
+
+It does **not** require evidence that only real staging activation can produce.
+
+### STAGING_ACCEPTED
+
+Requires actual staging:
+- TaskPlane adapter/claim/lease/fencing;
+- root action executor;
+- ANNEX A01–A23;
+- restart/response-loss/sibling concurrency/recovery evidence.
+
+### PRODUCTION_ELIGIBLE
+
+Requires:
+- STAGING_ACCEPTED;
+- existing release authorization valid;
+- production rollback ready;
+- freeze/NO-GO clear.
+
+### PRODUCTION_ACCEPTED
+
+Requires actual deployment:
+- production deployment/runtime readback;
+- authenticated business E2E;
+- external projection readback.
+
+### PROGRAM_COMPLETE
+
+Only after production acceptance:
+- existing Identity/Lineage original C01–C06 all accepted;
+- Program final acceptance all satisfied;
+- final root review proves no remaining acceptance gaps.
+
+The existing root acceptance contract is unchanged. Its full completion is
+consumed only by the final program-complete gate.
+
+## 5. State authority rules
+
+No new business authority is added.
+
+- caller_scan: read-only evidence producer;
+- WP0 inventories: read-only discovery;
+- Environment Profile: read-only host profile;
+- Retry Governor: decision/audit only;
+- SchedulabilityProof: short-lived diagnostic evidence;
+- SystemTruth: read-only derived view;
+- TaskPlane / existing claim transaction: authoritative task/claim/lease state;
+- existing mission/continuation path: root-action executor;
+- existing release Saga: release authority.
+
+No new Task DB, scheduler, mission store, release controller or authorization
+authority is introduced in R2.
+
+## 6. Migration
+
+- Existing mission/root/children: preserve IDs and acceptance.
+- Legacy durable task/job: attach metadata only; do not replace identity.
+- Schedulability proof: persist only through existing evidence/journal if
+  persistence is required.
+- No direct SQLite mutation outside existing TaskPlane repository.
+- G0 outputs remain shadow/read-only.
+
+## 7. Deployment status
+
+R2 code may proceed to live-authority rebase and repository-native review after
+its focused regressions pass.
+
+Deployment remains NO-GO until:
+- live preimages are refreshed;
+- full repository regressions pass;
+- atomic TaskPlane adapter is implemented and verified;
+- ANNEX A18–A23 pass;
+- real root-action executor consumes PENDING intents exactly once;
+- independent staging review is GO.
+
+## 8. Rollback
+
+Review candidate: discard candidate.
+
+Governed but undeployed commit: use existing successor/revert path; no shared
+branch reset/force push.
+
+Staging: disable feature/policy binding and preserve evidence.
+
+Production: existing release Saga rollback only.
+
+## 9. Deferred platform work
+
+WP3–WP10 remain dependency-gated backlog from Platform Baseline V4. R2 does not
+claim their acceptance and does not pre-build them.

+# G0 Evidence Coverage V2

+| WP2 | conservative decision layer | retry/suppress/reconcile/block decision | audit baseline on real operations; no scheduler authority |
+
+`g0_exit_eligible=false` in WP0a–d output is intentional. The G0 gate is a
+separate acceptance aggregation step and must reference the missing evidence
+listed above.
+
+WP3–WP10 remain dependency-gated backlog exactly as Platform Baseline V4
+defines; R2 does not silently redefine the long-term platform goal to U01–U09.

+
+## Program goal
+
+Preserve existing governance and tenant isolation while converging
+Identity/Lineage, ANNEX-2.3 execution integrity, Platform Generation G0 and the
+existing release/recovery path into one reviewable and recoverable program.
+
+## Existing dependency
+
+Identity/Lineage Mission:
+- `mission-f3af205b-7dd6-455f-a561-88f0294cc815`
+- root `task-133ad96e-e0d7-4202-934f-80c75053b11f`
+
+Its C01–C06 acceptance is immutable.
+
+## Program acceptance
+
+| Key | Acceptance |
+|---|---|
+| U01 | authority/runtime/production baseline reconciled and candidate bound to current Git authority |
+| U02 | existing Identity/Lineage mission identity and acceptance contract preserved; pre-production dependencies C01–C05 reconciled without claiming root complete |
+| U03 | ANNEX-2.3 A01–A23 accepted in real staging/lab as specified |
+| U04 | Platform Generation G0 Exit independently accepted; partial discovery output alone is insufficient |
+| U05 | unified governed commit + authority readback |
+| U06 | staging integrated E2E root→child→proof→ROOT_REVIEW→actual action→re-review |
+| U07 | production deployment + runtime/business/external readback accepted |
+| U08 | restart/response-loss/sibling concurrency/rollback/recovery accepted |
+| U09 | existing Identity/Lineage original C01–C06 fully accepted and final Program ROOT_REVIEW proves no remaining gaps |
+
+## Gate consumption
+
+- REVIEW_READY consumes no staging/production evidence.
+- STAGING_ACTIVATION_READY consumes governed commit/readback and lab evidence,
+  but no evidence that requires staging activation.
+- STAGING_ACCEPTED consumes live staging evidence.
+- PRODUCTION_ELIGIBLE consumes staging acceptance + release authorization.
+- PRODUCTION_ACCEPTED consumes live production evidence.
+- PROGRAM_COMPLETE consumes U01–U09 including final existing-root acceptance.
+
+## Autonomous rule
+
+Any child terminal:
+`child evidence → ROOT_REVIEW → reload original acceptance → query descendants
+→ next legal action`.
+
+A child/local/gate PASS closes only that scope. It never closes the Program by
+itself.
+
+## Naming
+
+New task display names retain:
+`TASK-<SAFE_USER_ALIAS>-<UTC>-R<ROOT8>-P<PARENT8>-D<DEPTH>-C<SEQ>-<PURPOSE>`.
+
+Authoritative lineage is persisted separately; existing durable IDs are not
+renamed/recreated.

+# AIOS Unified Platform Convergence R1 — 架构变更说明
+
+## 0. 决策摘要
+
+本变更将 **Identity/Lineage S3、ANNEX-2.3 R2 Auto-Claim、平台化 Phase-0、
+Governed Merge/Release** 收敛为一个新的上层 Program，而不是改写已存在
+Identity/Lineage Mission 的原始验收合同。
+
+核心原则：
+
+1. **新 Program，不重写旧 root。** 已有 Mission `mission-f3af205b-7dd6-455f-a561-88f0294cc815` 和 root
+   `task-133ad96e-e0d7-4202-934f-80c75053b11f` 原样保留，C01–C06 的 acceptance 不变。
+2. **唯一 Git authority 是 `beabd053961047f170e87e1110f2636dbd50f5fb`。** release-control runtime
+   `3c320aeb89d9ba8f0ed516abeb57252682b18983` 和 production `4642b74af62c89a505ae49241e805a5a88ca897f` 是不同平面，不得互相冒充。
+3. **恢复语义，不恢复旧拓扑。** 从 `3c320ae…` 选择性移植 SystemTruth/Execution
+   Integrity 语义，但不把该后继分支整体推回 main。
+4. **单一权威、只读聚合。** 新 inventory/caller_scan/Environment Profile/
+   Retry Governor 都是 evidence producer，不成为新持久化权威。
+5. **先评审，后部署。** 本 R1 是 Review Candidate；禁止在 Review Gate 通过前
+   进行 staging/production activation。
+
+## 1. 当前权威三平面
+
+| 平面 | OID | 含义 |
+|---|---|---|
+| Git authority / main | `beabd053961047f170e87e1110f2636dbd50f5fb` | 新候选唯一 source base |
+| release-control runtime | `3c320aeb89d9ba8f0ed516abeb57252682b18983` | 现有控制面运行字节，不是 main |
+| production baseline | `4642b74af62c89a505ae49241e805a5a88ca897f` | V2R2C2 生产 evidence closure |
+
+`beabd053961047f170e87e1110f2636dbd50f5fb -> 3c320aeb89d9ba8f0ed516abeb57252682b18983` 仅包含 10 个 SystemTruth/consistency 相关路径；
+现有 Identity/Lineage 27 文件候选与这 10 个路径无交集。因此 27 文件候选可以
+在 **重新读取 authority preimage 并通过 apply/check 后** 重新绑定
+`beabd053961047f170e87e1110f2636dbd50f5fb`，但不能复用旧 `3c320ae…` approval/base 记录。
+
+## 2. 新 Program 与既有 Mission 的关系
+
+### 2.1 新上层 Program（尚未在 live TaskPlane 创建）
+
+`goal_slug = AIOS-UNIFIED-PLATFORM-CONVERGENCE`
+
+实际 `mission_id/root_task_id` 必须由 live TaskPlane authority 创建并返回，
+本候选不预造 ID。
+
+### 2.2 既有 Identity/Lineage Mission（保留）
+
+- mission: `mission-f3af205b-7dd6-455f-a561-88f0294cc815`
+- root: `task-133ad96e-e0d7-4202-934f-80c75053b11f`
+- owner: `local-owner-authority`
+- alias: `U9CA8400F7`
+- legacy durable task: `TASK-P0-CHATGPT-BRIDGE-V2-CONTROL-PLANE-CONVERGENCE-INTEGRATE-20260913T184412Z-19b7`
+- legacy job: `job-7457a322d5f9d6931c7cd99ce3ec6c18`
+
+该 Mission 作为新 Program 的 Track A 依赖/子目标；其历史 task/job/idempotency
+身份不可为了新命名而重建。
+
+## 3. 四条 Track
+
+### Track A — Identity / Lineage S3
+
+目标保持：
+`root → child → terminal proof → ROOT_REVIEW → actual next action → execution → root re-review`
+
+包含：
+- C01 governed candidate commit/readback
+- C02 staging lineage policy activation
+- C03 root-action executor binding
+- C04 legacy attach
+- C05 live failure/replay/concurrency E2E
+- C06 production convergence
+
+### Track B — ANNEX-2.3 R2 Auto-Claim / Execution Integrity
+
+新链：
+`admission/preflight → SchedulabilityProof → discovery → claim-time authoritative recheck
+→ lease/fencing/CAS → execution → heartbeat/progress → result/evidence → readback/acceptance`
+
+R1 已实现 review-candidate 代码：
+- `task_plane/schedulability.py`
+- `task_plane/auto_claim.py`
+- A01 风格多 blocker、scope/capability/heartbeat/auth/capacity/freeze/dependency/lease
+  检查
+- proof 仅为诊断证据，不是 bearer credential
+- claim 前完整 authority recheck
+
+**R1 不直接替换现有 claim 路径**；必须在 staging 评审时通过 adapter 绑定后才可启用。
+
+### Track C — Platform Phase-0 / Generation G0
+
+仅包含批准的第一 generation：
+
+- WP0a Version/Baseline inventory
+- WP0b Git writer inventory
+- WP0c Authorization inventory
+- WP0d Canonical/Digest inventory
+- WP0e caller_scan
+- WP1 Environment Capability Profile
+- WP2 Retry/Toil Governor
+
+这些组件只读或纯决策：
+- 不新增 version authority
+- 不新增 canonical authority
+- 不写业务状态
+- `UNKNOWN` 永远不能被 caller_scan 降级为 orphan
+- Retry Governor 只返回决策，不执行 retry
+
+禁止提前引入 WP8 MissionRun store / WP9 新 Release Saga 控制面。
+
+### Track D — Governed Merge / Staging / Release
+
+顺序：
+`Review Gate → governed child commit/readback → staging activation → integrated live E2E
+→ release candidate/acceptance → production convergence`
+
+部署不是本 Review Candidate 的交付内容。
+
+## 4. 状态权威边界
+
+| 维度 | 权威 |
+|---|---|
+| Mission/root/lineage | TaskPlane/Mission authority |
+| claim/heartbeat/task revision | TaskPlane |
+| Owner/TaskPrincipal authorization | existing auth/Admission authority |
+| Writer lease / governed write | existing writer/lease authority |
+| source bytes/ref | Git authority |
+| deployed runtime | runtime readback |
+| external projection | external projection readback |
+| caller liveness evidence | caller_scan evidence only |
+| retry decision | Retry/Toil Governor decision only |
+
+新模块不得建立第三份真值数据库。
+
+## 5. 关键架构优化
+
+### 5.1 动态 readiness 与不可变身份分离
+
+Planner 选择身份（mission/root/child/route/authority digest）不可变；
+`readiness_class` 是动态观察，可在未激活、未终态时通过 revision/CAS 单调向
+“更可执行”方向推进。active claim/READY/DONE 后冻结。
+
+### 5.2 Legacy reader 无副作用
+
+旧 `GET /v1/tasks/{id}` 可能触发全局 lease expiry。R1 改为：
+1. 通过 `/v1/tasks/{id}/events` 做 Bearer 认证；
+2. Task row 从 authority SQLite 以 `mode=ro` + `PRAGMA query_only=ON` 精确读取；
+3. 只允许终态；
+4. readback ref 同时绑定 events SHA 和 DB revision；
+5. 不暴露 `lease_token_hash`。
+
+### 5.3 SchedulabilityProof 是短寿命诊断证据
+
+Proof 绑定 task/worker/actor、revision/generation、capabilities、scope digest、
+authorization revision、capacity/dependency/freeze/lease 观察；TTL ≤ 300s。
+真正 claim 必须重读 authority 并完全一致，proof 本身不能授权。
+
+### 5.4 Root Action Provider / Executor 分离
+
+Provider 只把 root review 映射到准备计划；Executor 使用现有 continuation/recovery
+路径执行。不能让 planner 把“PENDING”当成“已执行”。
+
+## 6. 数据迁移策略
+
+- 既有 Mission/root/children：不重建。
+- legacy `TASK-P0-CHATGPT-BRIDGE-V2-CONTROL-PLANE-CONVERGENCE-INTEGRATE-20260913T184412Z-19b7` / `job-7457a322d5f9d6931c7cd99ce3ec6c18`：仅 attachment，不改 identity。
+- 新 Platform inventory：无持久业务迁移。
+- 新 schedulability proof：短寿命诊断记录；若持久化，必须复用现有 TaskPlane
+  evidence/journal，禁止新数据库。
+- SystemTruth：只读派生，不能成为第三控制面。
+
+## 7. Review Gate
+
+### R0 — 架构与代码评审
+必须同时满足：
+- 新 Program 与旧 Mission 边界明确
+- base 重新绑定 `beabd053961047f170e87e1110f2636dbd50f5fb`
+- 变更路径均有 ChangeEnvelope
+- 新代码定向测试 PASS
+- 旧候选继承证据有效
+- 无新增业务权威/数据库
+- legacy reader 不再使用可变 GET
+- planner readiness 动态规则经过测试
+- R2 proof 不能直接授权 claim
+
+### R1 — Governed Commit Gate
+在 R0 GO 后：
+- live reread authority HEAD
+- 所有 preimage SHA 重新采集
+- exact apply/diff
+- governed writer commit
+- authority branch/commit readback
+
+### R2 — Staging Gate
+- authenticated principal/tenant
+- identity/lineage/read isolation
+- auto-claim adapter
+- root action real executor
+- restart/response-loss/sibling race
+- ANNEX A01–A23
+
+### R3 — Production Gate
+只有 original root acceptance + Program acceptance 全部证据闭环，
+并完成 rollback/recovery 验证后才能生产收敛。
+
+## 8. 回滚
+
+- Review candidate：直接丢弃候选，无线上副作用。
+- Governed commit 未发布：通过正式 successor/revert，不 reset/force push。
+- Staging activation：关闭 feature/policy binding，保留 evidence。
+- Production：只走既有 release Saga/rollback contract。
+
+## 9. 明确不做
+
+- 不把 `3c320aeb89d9ba8f0ed516abeb57252682b18983` 恢复为 main。
+- 不新建任务数据库、第二 scheduler、第二 release authority。
+- 不把 caller_scan/Retry Governor/SystemTruth 作为写权威。
+- 不把局部测试 PASS 当 root/program 完成。

+# TaskPlane task identity and lineage
+
+TaskPlane can bind admitted tasks to an authenticated owner principal and mission, assign stable root/parent lineage, and persist a root review after a child reaches a proof-bearing terminal state. The integration is opt-in through `TaskPlaneService(..., lineage_policy=...)`; existing services without a lineage policy retain their existing behavior.
+
+## Authority boundary
+
+`PrincipalLineageBinding` is service configuration. It maps the identity returned by the HTTP authenticator to `owner_principal_id`, `mission_id`, a safe display alias, and a registered root-acceptance policy reference. HTTP admission overwrites `issuer` with that authenticated identity. Direct in-process callers must pass an identity already verified by their boundary through `actor_identity`.
+
+Client task metadata is never an identity or terminal-proof source. `aios_task_lineage`, the derived display name, and the lineage request digest are server-owned and rejected on new lineage admission. Similar-looking client metadata such as `owner_principal_id`, `mission_id`, or `terminal_evidence_proven` remains ordinary opaque metadata and cannot override the dedicated TaskPlane authority columns or the validated terminal-proof tables.
+
+Root and child creation use the existing TaskPlane SQLite connection and transaction fence. The store adds authority columns and lineage sequence, terminal proof, root review, and root action tables to that database. It does not create a second TaskPlane database. The original task ID, claim ID, idempotency key, budget transaction, event journal, and revision CAS remain authoritative.
+
+## Admission and delegation
+
+A root admission requires:
+
+- an authenticated identity with both TaskPlane capability and a `PrincipalLineageBinding`;
+- a registered acceptance evaluator for the configured reference;
+- no client-supplied reserved lineage metadata.
+
+The request digest is computed before derived metadata is added. An identical idempotency replay returns the original task; a changed request, principal, mission, or parent conflicts. The persisted TaskPlane `created_at` is the same timestamp serialized into lineage metadata.
+
+Task detail and list responses expose the server-bound name as `display_name`, including list responses that omit the full plan. Durable task and job identifiers remain unchanged.
+
+Delegation currently creates only `CHILD` relations. It preserves the root owner, mission, acceptance reference, budget constraints, capability/risk monotonicity, and existing delegation transaction. The caller must resolve to the same server-owned root authority. Concurrent sibling admission uses the same SQLite write transaction to reserve unique sibling sequences.
+
+`SUCCESSOR` and `RECOVERY` are intentionally not admitted by this binding because the current TaskPlane service does not expose a formal continuation/supersession authority contract. Adding those relations requires a separate source-of-authority design; callers must not encode them in metadata.
+
+## Proven terminal review
+
+The proof-bearing result path first applies the existing claim identity, lease, operation digest, evidence, result digest, event-chain, and evidence-chain checks. In the same transaction, a final child result records a terminal proof and triggers one `ROOT_REVIEW`. The review CAS advances the root revision and persists the exact trigger child and terminal revision.
+
+The resulting next legal action is stored idempotently with status `PENDING`. `PENDING` means a durable action request exists. It does not mean a planner completed the root, created another child, recovered work, or crossed an owner boundary.
+
+The optional `TaskPlaneService.consume_one_root_action()` consumes one persisted action through a root claim and a durable effect ledger. Mission configuration must provide an authoritative plan builder and acceptance verifier, and the service must receive a real `root_action_executor`. Missing execution wiring returns `BLOCKED`; the loopback Mission bootstrap adapter alone does not execute root actions. Plans survive process restart, and an unknown effect must be reconciled against its existing authority Job before execution can proceed. Worker metadata cannot supply that Job identity or certify a completed effect.
+
+`PublicBridgeRootActionExecutor` is an adapter for authenticated public Bridge operations, not a deployed worker. Runtime integration must supply its trusted authentication and transport, then prove the actual Job result and repository readback. After an execution receipt, the consumer rechecks the stored original root acceptance and descendants. Root completion and child admission share the store's transaction boundary; a child result alone cannot close the root.
+
+Direct worker completion of a lineage root is rejected. Root completion is legal only when the registered evaluator returns satisfied conditions backed by durable evidence references and the root review selects `ROOT_COMPLETE`. This integration persists that legal decision and request; it does not itself change the root task to `COMPLETED`.
+
+After restart, `resume_terminal_review(child_task_id=...)` reads the durable terminal proof. If the trigger already has a review, it validates and returns that exact review and action receipt without running the evaluator again. This freezes the decision against evaluator drift and prevents a lost response from producing a second review. Tests close and reopen the SQLite database before treating this state as durable; visibility through the writing connection inside its transaction is only transaction-local.
+
+The legacy `/fail` and `/cancel` paths do not construct a validated `ResultEnvelope` and therefore do not create this terminal proof or claim root-review completion. Use the proof-bearing result endpoint when terminal lineage review is required.
+
+## Minimal service configuration
+
+```python
+from app.aios_task_lineage import AcceptanceCondition, RootAcceptanceSnapshot
+from app.task_plane.api import TaskPlaneService
+from app.task_plane.lineage_store import PrincipalLineageBinding, TaskLineagePolicy
+
+
+def evaluate_root(root, descendants):
+    refs = tuple(
+        ref
+        for child in descendants
+        if child.terminal_evidence_proven
+        for ref in child.evidence_refs
+    )
+    return RootAcceptanceSnapshot(
+        (
+            AcceptanceCondition(
+                key="original-root-acceptance-not-yet-evaluated",
+                # Replace with the original mission's authoritative acceptance
+                # checks. A completed child alone cannot prove root completion.
+                satisfied=False,
+                evidence_refs=refs,
+            ),
+        )
+    )
+
+
+lineage_policy = TaskLineagePolicy(
+    principal_bindings=(
+        PrincipalLineageBinding(
+            authenticated_identity="spiffe://aios/owner/example",
+            owner_principal_id="principal-example",
+            mission_id="mission-example",
+            preferred_owner_alias="OWNER",
+            root_acceptance_ref="policy://root/example-v1",
+        ),
+    ),
+    acceptance_evaluators={"policy://root/example-v1": evaluate_root},
+)
+service = TaskPlaneService(store, policy=policy, lineage_policy=lineage_policy)
+```
+
+An evaluator that is missing, returns no conditions, or marks a condition satisfied without evidence fails closed. It cannot be supplied by task metadata.
+
+Existing tasks receive empty authority-column defaults during additive schema
+initialization. This does not infer ownership from their metadata or attach old
+jobs to a new root. Migrating an actual legacy task requires an authoritative
+owner/mission binding; this change does not fabricate one or alter a Job DB.
+
+## Canonical Mission issuance
+
+When discovery establishes that no root exists, the optional `MissionAuthority`
+can allocate the first root. `POST /missions` accepts only `goal_slug` and
+`original_acceptance`, with an `Idempotency-Key`. The authenticated principal
+must have a server-configured `MissionPrincipalBinding`. Mission/root IDs,
+owner binding, safe alias, UTC creation time and acceptance reference are
+allocated and persisted by the authority in the existing TaskPlane database,
+in the same transaction as root creation. They are never request identity
+fields. An exact retry returns the original identity; a changed contract with
+the same principal/idempotency key conflicts. `GET /missions/{mission_id}`
+requires the same owner binding and returns the persisted acceptance and root.
+
+Acceptance JSON is data. A service-owned verifier must independently establish
+its conditions; absence of a registered verifier keeps acceptance unmet.
+Creating the root or attaching an arbitrary evidence string cannot satisfy it.
+The Mission authority and ordinary worker execution are separate: enabling
+Mission admission does not grant worker claim or result permissions.
+
+`app.aios_task_mission_authority_server` is a narrow loopback staging adapter
+for environments with the existing registered Owner signature verifier. It
+accepts `POST /v1/signed-request` containing exactly `request`, `signature` and
+`key_id`. The request schema is `aios.signed-mission-request.v1`, audience is
+`aios.task-mission-authority.staging.v1`, and the signed fields bind method,
+path, body, idempotency key, issued/expiry timestamps and nonce. The maximum
+validity is 300 seconds. The existing `aios-owner-approval-v1` verifier checks
+the signature, and its registered signer identity is the service actor.
+Neither a bearer belonging to Shadow nor an unsigned owner name establishes
+that identity. The adapter does not load private keys or sign requests.
+
+Allowed signed operations are Mission create/read and
+`POST /tasks/{authority-returned-parent}/delegate`. Mission delegation issues
+child IDs on the server and uses a durable, principal-scoped request mapping
+for retries. The adapter exposes no Git writer, worker claim, terminal result,
+legacy recovery, production deployment or arbitrary execution route. Deployment
+of this bootstrap adapter is staging evidence, not a governed commit receipt
+or proof that `PENDING` root actions execute.

+"""端到端实施证明：owner-based authorization 现场装配 + 生产入口闭环（集成测试）。
+
+本文件位于真实 dev 树（不是玩具），直接 import 生产模块并真实执行：
+
+- 使用 OWNER_AUTHORIZATION_MODEL.md 的**参考授权物** `azn-owner-gw-v1`
+  （policy_fingerprint = sha256:5a2618d6...），经 `FieldOwnerAuthorizationAuthority`
+  登记为"Owner 的正式一次授权"。
+- 用 `FieldGovernedWriterFactory`（组合根）把 7 个适配器装配到
+  `GovernedWriterAutomation.acquire_verified()` 生产入口。
+- 证明：Owner 一次授权后，Agent 在 `legacy_global_writes_enabled=false` 前提下
+  自主跑完完整受治理写链（epoch -> claim -> TaskLease -> TaskPrincipal -> job
+  -> live CAS -> WriterLease），返回 `GovernedWriterSession`（WRITER_LEASED）。
+- 证明 fail-closed：未知 / 未登记授权引用、authority 未装配、缺 receipt、
+  EXPIRED 任务无预签 recovery，都必须在**任何副作用之前**阻断。
+
+Windows 说明：与既有 T2/T3 同，用 `mkdtemp()` + `gc.collect()` 再 `rmtree`。
