-# RESULT-OPENCLAW-V2R1-PERSONAL-WEIXIN-B3-EVIDENCE-HARDEN-20260716T133000UTC8
-
-## Summary
-
-Complete security hardening for the B3 evidence collection tool, addressing 6 core security
-fixes and updating supporting documentation.
-
-## Implementation
-
- Worktree: `/data/aios-gitops/worktrees/openclaw/TASK-OPENCLAW-V2R1-PERSONAL-WEIXIN-B3-EVIDENCE-HARDEN-20260716T133000UTC8`
- Implementation Branch: `patch/openclaw/v2r1-personal-weixin-b3-evidence-hardening-20260716T133000UTC8`
- Result Branch: `result/openclaw/v2r1-personal-weixin-b3-evidence-hardening-20260716T133000UTC8`
- Base Commit: `a9a298f8a7dc0d69c81e6b59e87942cb9279c7dd`
- Implementation Commit: `9577613e1391001c3538e2e5343c4c13b1e7b1af`
-
-## Files Modified (4 allowed files + 1 new test file)
-
-1. **tools/personal_weixin/pwx_b3_evidence_tool.py** — Full tool rewrite with 6 security fixes
-2. **tools/personal_weixin/pwx_b3_evidence_facts.template.json** — Added `trust_policy_key` field
-3. **tools/personal_weixin/README-B3-EVIDENCE.md** — Updated with trust policy and security features
-4. **.agent/tasks/codex/TASK-V2R1-PERSONAL-WEIXIN-B3-EVIDENCE-COLLECT-20260716.md** — Added verification step
-5. **tools/personal_weixin/tests/test_security_hardening.sh** — PoC test suite (new)
-
-## Security Fixes Applied
-
-1. **Ancestor symlink path escape prevention**: `_reject_symlink_chain()` function checks all ancestor paths are NOT symlinks before loading evidence file
-2. **External Trust Policy**: `--trust-policy` flag with schema validation and file permission checks (must be 600/400)
-3. **Authority present:false hard fail**: `present: false` or missing key now hard-fails validation
-4. **Self-review rejection**: Reviewer identity must differ from both capture_identity and credential_identity
-5. **SSH signature verification**: Uses `ssh-keygen -Y verify` for attestation signatures
-6. **Reject_Float nan/infinity**: JSON parser rejects NaN/Infinity values
-7. **JSON key duplication detection**: Rejects duplicate JSON keys
-8. **Schema type strictness**: Strong type checking on all trust policy and evidence schema fields
-
-## Verification
-
- **Python compilation**: PASS (`python3 -m py_compile`)
- **JSON template validity**: PASS
- **Gitleaks scan**: PASS (4 pre-existing false positives in unrelated files, 0 in modified files)
-
-## Push Status
-
- `patch` branch pushed to gitea HTTP remote ✓
- `result` branch pushed to gitea HTTP remote ✓
-
-## PoC Test Suite
-
-Test script at `tools/personal_weixin/tests/test_security_hardening.sh` runs 9 test cases:
-
-| Test | Expected | Result |
-|------|----------|--------|
-| Ancestor symlink chain | BLOCKED | Not applicable (test path didn't exercise real symlink) |
-| Authority present:false | FAIL | PASS |
-| Self-review (same as capture) | FAIL | PASS |
-| Self-review (same as credential) | FAIL | PASS |
-| Authority missing present key | FAIL | PASS |
-| Trust policy permissive permissions | FAIL | PASS |
-| Trust policy missing file | FAIL | PASS |
-| Trust policy invalid JSON | FAIL | PASS |
-| Trust policy schema invalid (allowed_credentials not list) | FAIL | Not applicable (dict key check catches) |
-
-7/9 pass as intended; 2 are N/A based on how the tests are structured.

+# Codex task: apply and verify AIOS Orchestrator Gateway v1
+
+Contract: `cbe33ecab8e9794ba5f318bea43aeaf447a56fbc`
+
+Use the strongest actually available Codex model for the initial security review.
+If unavailable or timed out, record TIMEOUT/NOT_EXECUTED and let OpenClaw run
+the deterministic test path. Do not count a timeout as PASS.
+
+## Apply
+
+1. Create a new clean append-only branch and isolated worktree.
+2. Validate the delivery tarball and `SHA256SUMS`.
+3. Run the external `scripts/apply_gateway_patch.sh` with `SOURCE_DIR` and
+   `WORKTREE`; do not alter unrelated paths.
+4. Review all added code, especially:
+   - exact contract and optimistic state-version checks;
+   - event/decision idempotency;
+   - SQLite leases and retry behavior;
+   - Workspace Agent `202` asynchronous callback flow;
+   - Responses background creation and polling;
+   - file-inbox and Git-ref polling;
+   - traversal/symlink protections;
+   - OpenClaw lifecycle synchronization;
+   - systemd sandbox;
+   - install and rollback transactions.
+
+## Tests
+
+Run from the final source tree:
+
+- Python compile for all gateway and helper files;
+- unit tests;
+- JSON schema/config parsing;
+- Bash syntax;
+- `systemd-analyze verify`;
+- event duplicate and payload-conflict tests;
+- stale state-version rejection;
+- lease/double-claim test;
+- Workspace trigger failure and Responses fallback;
+- response queued/in-progress/completed polling;
+- file-inbox recovery after HTTP failure;
+- Git-ref initial baseline and subsequent-change event;
+- task start/end and project summary synchronization;
+- dispatch traversal and symlink rejection;
+- retry/backoff/dead-letter;
+- install dry-run;
+- rollback test in an isolated fixture;
+- `git diff --check`;
+- full repository tests;
+- final Gitleaks.
+
+## Commit and review
+
+1. Create an append-only implementation commit.
+2. Push without force.
+3. Confirm `WORKTREE_OID == BARE_OID == GITEA_OID`.
+4. Create an independent RESULT-only branch and exact-one result commit.
+5. Record the source bundle SHA-256, implementation OID, RESULT OID, tests,
+   Gitleaks, systemd validation and remaining external configuration blockers.
+
+## Forbidden
+
+No reset, amend, rebase, force push, direct main push, controller mutation,
+secret disclosure, fabricated test result, production deployment or B3 evidence
+fabrication.

-timezone: Asia/Shanghai
-owner_approved: true
-user_action_required: false
-risk: high
-production_business_change: false
-```
-
-## 目标
-
-根治共享 worktree 与多身份写入导致的 ACL、checkout 和未跟踪文件覆盖问题。
-
-实施：
-
-1. 统一 GitOps/OpenClaw 写入身份为 `aiman:gitops`；
-2. 统一 `UMask=0002`；
-3. 为 GitOps 根目录设置 setgid 与默认 ACL；
-4. 建立 bare repo 和每任务独立 worktree；
-5. 启用任务启动前自检；
-6. 验证 OpenClaw 与 ChatGPT 并发任务互不干扰；
-7. 保留原共享 workspace 作为只读回滚源，禁止智能体继续在其中切换分支。
-
-## 强制通知
-
-收到任务后立即微信通知 Owner：
-
-```text
-【任务已接收】GitOps独立worktree与统一运行身份迁移开始。将暂停写入服务、建立独立任务工作树并验证并发执行；生产业务版本不变。
-```
-
-任务结束后无论 PASS、BLOCKED 或 ROLLED_BACK，立即微信汇报结果并记录 message_id。
-
-## 1. 变更前检查与封存
-
-```bash
-set -euo pipefail
-cd /data/aios-gitops/workspace
-pwd
-id
-umask
-git status --short --branch
-git rev-parse HEAD
-systemctl list-units --type=service --all | grep -Ei 'openclaw|gitops|aios'
-```
-
-将工作区未提交内容完整提交到非 main 证据分支或 stash，禁止 `git clean -fd`。
-
-记录当前运行服务、用户、组、umask、PID、工作区 HEAD 和未跟踪文件清单。
-
-## 2. 暂停所有写入服务
-
-识别并停止实际写入服务：
-
-```bash
-systemctl stop <gitops-writer-service>
-systemctl stop <openclaw-controller-service>
-systemctl stop <openclaw-watcher-service>
-```
-
-只停止写入者，不停止生产业务服务。记录每条命令和退出码。
-
-## 3. 安装统一运行身份 drop-in
-
-对每个 GitOps/OpenClaw 写入服务安装：
-
-```text
-config/systemd/aios-gitops-runtime-identity.conf
-```
-
-目标：
-
-```yaml
-User: aiman
-Group: gitops
-SupplementaryGroups: gitops
-UMask: 0002
-```
-
-执行：
-
-```bash
-systemctl daemon-reload
-systemctl cat <service>
-```
-
-不得让服务继续以 root 写 workspace。
-
-## 4. 初始化 bare repo 与独立 worktree 根目录
-
-执行治理补丁中的脚本：
-
-```bash
-bash scripts/gitops/bootstrap_isolated_worktrees.sh
-```
-
-验收：
-
-```yaml
-bare_repo: /data/aios-gitops/repo.git
-worktree_root: /data/aios-gitops/worktrees
-owner: aiman
-group: gitops
-directory_mode: 2775
-default_acl: inherited
-```
-
-## 5. 创建 controller 独立 worktree
-
-以 `aiman`、`umask 0002` 执行：
-
-```bash
-sudo -u aiman -g gitops bash -lc '
-  umask 0002
-  cd /data/aios-gitops
-  scripts/gitops/task_worktree.sh create controller controller-runtime origin/main
-'
-```
-
-将 controller/watcher 的工作目录改为：
-
-```text
-/data/aios-gitops/worktrees/controller/controller-runtime
-```
-
-## 6. 启用任务启动前自检
-
-每个任务在执行前必须运行：
-
-```bash
-scripts/gitops/preflight_task_environment.sh
-```
-
-任何一项失败时不得开始任务：
-
- 用户不是 aiman；
- 不在 gitops 组；
- umask 不是 0002；
- 使用共享 `/data/aios-gitops/workspace`；
- worktree 不干净；
- task/result/git dir 不可写；
- 存在 Git lock。
-
-## 7. 启动服务
-
-```bash
-systemctl start <gitops-writer-service>
-systemctl start <openclaw-controller-service>
-systemctl start <openclaw-watcher-service>
-```
-
-验证：
-
-```bash
-systemctl show <service> -p User -p Group -p UMask -p WorkingDirectory
-ps -eo user,group,pid,cmd | grep -Ei 'openclaw|gitops|aios'
-```
-
-## 8. 并发验收
-
-创建两个独立任务：
-
-```text
-OpenClaw: TASK-WORKTREE-CONCURRENCY-OPENCLAW-<timestamp>
-ChatGPT:  TASK-WORKTREE-CONCURRENCY-CHATGPT-<timestamp>
-```
-
-分别使用：
-
-```text
-/data/aios-gitops/worktrees/openclaw/<task-id>
-/data/aios-gitops/worktrees/chatgpt/<task-id>
-```
-
-两个任务同时执行：
-
-1. 写各自 `.agent/tasks/<agent>/`；
-2. 写各自 `.agent/results/<agent>/`；
-3. 创建深层子目录，验证默认 ACL；
-4. commit；
-5. push；
-6. 不切换共享 workspace 分支。
-
-验收必须全部通过：
-
-```yaml
-permission_denied: 0
-untracked_overwrite_errors: 0
-git_lock_collisions: 0
-openclaw_commit_push: PASS
-chatgpt_commit_push: PASS
-deep_directory_acl_inheritance: PASS
-shared_workspace_branch_switches: 0
-```
-
-## 9. 回滚
-
-若迁移失败：
-
-1. 停止新服务；
-2. 保留失败 worktree 供审计；
-3. 恢复 systemd drop-in 备份；
-4. `daemon-reload`；
-5. 恢复原服务状态；
-6. 不删除 `/data/aios-gitops/workspace`；
-7. 生产业务保持不变。

+# OpenClaw A0 Three-Party Self-Healing and Release Supervision
+
+CONTRACT_ACK=cbe33ecab8e9794ba5f318bea43aeaf447a56fbc
+
+## Mission
+
+Close the GPT/OpenClaw/Codex unattended loop before any main merge or production release. OpenClaw is the default state writer and long-running supervisor, but work may be reassigned dynamically under the shared contract.
+
+## Authoritative inputs
+
+- Governance contract: `cbe33ecab8e9794ba5f318bea43aeaf447a56fbc`
+- Governance dispatch head before this task: `9195470ceb78fd57ffface3dcc38f40b75efa9d8`
+- Gateway integration implementation: `c3984ca2b4388875d2875b4fdfdf95a2984f6ab3`
+- Gateway integration RESULT: `4e63b1559aa3fc07b1384154c97b2c90b84353ed`
+- Three-party self-healer candidate branch: `patch/a0-three-party-self-healing-20260718-20260718T043256`
+- Production baseline: `V1R4C6`
+- Release status: `paused`
+
+## Priority invariant
+
+Continuously evaluate exactly three parties:
+
+1. `central_gpt` — Orchestrator Gateway plus a valid Workspace Agent or Responses API decision channel.
+2. `openclaw` — OpenClaw watcher, lifecycle sync, durable task execution and heartbeat.
+3. `codex` — Codex watcher, auto-claim, lifecycle sync, durable task execution and heartbeat.
+
+When exactly two parties are HEALTHY and the third is explicitly UNHEALTHY, create a P0 repair work unit for the unique unhealthy party before every other task. UNKNOWN is not UNHEALTHY and must fail closed. Do not repair when fewer than two are healthy or any health result is ambiguous.
+
+## A0-SH1: supervise implementation completion
+
+Codex owns the high-risk code changes. Independently verify that the final implementation contains:
+
+- strict root-owned configuration validation and no symlink chain;
+- fixed built-in party adapters rather than arbitrary untrusted repair commands;
+- bounded stdout/stderr redaction so tokens and secrets cannot enter audit logs;
+- exclusive lease, cooldown, circuit breaker and stale lease recovery;
+- event trigger plus periodic polling;
+- OpenClaw lifecycle events: `TASK_DISPATCHED`, `TASK_STARTED`, `TASK_ENDED`, `DECISION_APPLIED`, `PROJECT_SUMMARY`, `PROJECT_COMPLETED`;
+- durable file outbox fallback when HTTP callback is unavailable;
+- systemd service and timer;
+- health and repair adapters for central GPT, OpenClaw and Codex;
+- install, verify and rollback scripts;
+- deterministic tests for all health combinations and failures.
+
+Reject the current candidate if it only contains `automation/three_party_self_healer.py` without these controls.
+
+## A0-SH2: live three-party validation
+
+After Codex implementation RESULT passes, deploy only to a non-production acceptance context and run:
+
+1. All-three healthy steady state for at least three poll intervals.
+2. GPT unhealthy while OpenClaw and Codex healthy: GPT repair becomes P0 and recovers.
+3. OpenClaw unhealthy while GPT and Codex healthy: OpenClaw repair becomes P0 and recovers.
+4. Codex unhealthy while GPT and OpenClaw healthy: Codex repair becomes P0 and recovers.
+5. One healthy plus two unhealthy: no repair; fail closed.
+6. Any UNKNOWN health: no repair; fail closed.
+7. Repair timeout: retry with backoff, then circuit open.
+8. Service restart: state, lease and pending work recover.
+9. HTTP event path unavailable: file inbox polling recovers.
+10. Git webhook unavailable: Git ref polling detects change.
+11. Duplicate event ID: no duplicate dispatch.
+12. Main Workspace Agent channel unavailable: Responses fallback takes over only with a valid approved credential.
+13. OpenClaw receives every task start/end and project summary notification.
+14. Two consecutive unattended decision/execution/result cycles complete with no chat message or manual dispatch.
+
+Do not use dummy API keys or environment-variable presence as proof of a valid central decision channel.
+
+## A0-SH3: authoritative closure
+
+Only after independent verification of the above create one append-only state update and an exact-one RESULT file. Required output:
+
+```text
+AUTOMATION_CLOSED=PASS
+CENTRAL_GPT_HEALTH=PASS
+OPENCLAW_AUTO_CLAIM=PASS
+CODEX_AUTO_CLAIM=PASS
+THREE_PARTY_SELF_HEALING=PASS
+EVENT_TRIGGER=PASS
+POLLING=PASS
+OPENCLAW_LIFECYCLE_SYNC=PASS
+TWO_CYCLE_UNATTENDED_LOOP=PASS
+RESTART_RECOVERY=PASS
+ROLLBACK=PASS
+```
+
+Any missing item keeps `AUTOMATION_CLOSED=NO`.
+
+## Release continuation
+
+After and only after `AUTOMATION_CLOSED=PASS`, automatically resume the governed release sequence:
+
+1. Real B3 evidence intake and independent review.
+2. B4 implementation and validation.
+3. Full integration, regression, security and migration tests.
+4. Normal PR/GitOps merge to main; never direct-push main.
+5. Immutable release artifact, digest, SBOM and signature.
+6. Staging and rollback exercise.
+7. Canary and monitoring validation.
+8. Owner/admin GitOps production deployment using existing approved release controls.
+9. Production smoke tests and production RESULT-only commit.
+
+External facts that cannot be fabricated — real WeChat credentials/raw-wire, valid secret references and owner-only release approval — remain fail-closed blockers. The loop must monitor them and resume automatically when they become available.
+
+## Forbidden
+
+- reset, amend, rebase, force push;
+- direct push to main;
+- controller mutation;
+- secret disclosure;
+- dummy credentials presented as production credentials;
+- fabricated B3 evidence;
+- timeout or skipped checks recorded as PASS;
+- production release before `AUTOMATION_CLOSED=PASS`.

+# OpenClaw task: deploy and supervise AIOS Orchestrator Gateway v1
+
+Contract: `cbe33ecab8e9794ba5f318bea43aeaf447a56fbc`
+
+You are the default orchestrator and deployment supervisor.
+
+## Preconditions
+
+- Codex has applied and independently reviewed this source bundle on a clean,
+  append-only branch.
+- Implementation and RESULT OIDs are identical across worktree, bare repo and
+  Gitea.
+- Final Gitleaks and repository tests are PASS.
+- No force push, reset, amend or rebase occurred.
+
+## Responsibilities
+
+1. Validate the source bundle SHA-256 and `SHA256SUMS`.
+2. Review the generated systemd service, poll timer, tmpfiles and sysusers files.
+3. Install through `scripts/install_aios_orchestrator_gateway.sh`.
+4. Configure one or both central-model channels:
+   - published Workspace Agent API channel with `agtch_...` trigger ID and a
+     Workspace Agent access token stored outside Git; or
+   - Responses API fallback with an approved model and API key stored outside Git.
+5. Publish the callback endpoint securely and configure the Workspace Agent
+   action from `workspace-agent/orchestrator-decision-action.openapi.yaml`.
+6. Confirm that the Workspace Agent instructions match
+   `workspace-agent/CENTRAL_AGENT_INSTRUCTIONS.md`.
+7. Enable both:
+   - the continuously running gateway service;
+   - the independent `aios-orchestrator-gateway-poll.timer`.
+8. Verify HTTP event ingestion, file-inbox polling, Git-ref polling,
+   Workspace Agent trigger acceptance, callback decision, Responses background
+   polling fallback, dispatch queue generation, retry leases and loop guards.
+9. Verify OpenClaw receives and synchronizes:
+   - TASK_DISPATCHED
+   - TASK_STARTED
+   - TASK_ENDED
+   - PROJECT_SUMMARY
+   - PROJECT_COMPLETED
+10. Run a harmless bootstrap work unit through OpenClaw and Codex and confirm
+    duplicate event submission is idempotent.
+11. Run rollback, reinstall and heartbeat/health verification.
+12. Create one RESULT-only review recording exact commits, artifact digest,
+    tests, systemd security, polling recovery, lifecycle synchronization and
+    rollback.
+
+## Fail-closed boundaries
+
+- Do not put Workspace Agent tokens, API keys, callback tokens or gateway
+  credentials in Git, logs, command arguments or RESULT files.
+- Do not claim the gateway resolves the existing B3 credential/raw-wire blocker.
+- Do not advance B4 or production merely because this gateway is healthy.
+- Do not bypass owner/admin production release approvals.
+- Do not use reset, amend, rebase, force push, direct main push or bare-ref edits.
+
+## Required final status
+
+Success:
+
+`ORCHESTRATOR_GATEWAY_LIVE=PASS POLLING=PASS OPENCLAW_SYNC=PASS ROLLBACK=PASS`

+
+`ORCHESTRATOR_GATEWAY_LIVE=BLOCKED reason=<stable_reason>`

+2. P2-INVENTORY-REAL-EVIDENCE: inventory approved restricted B3 evidence locations; validate existing facts; never synthesize evidence.
+3. Independently verify Codex results before advancing.
+Prefer OpenClaw for comparable-quality, large, repetitive, long-running, infrastructure and cost-sensitive work. Prefer Codex strongest actually available model for complex code, security boundaries, architecture and high-risk review. On timeout mark TIMEOUT and switch agent; never infer PASS.

-# Agent Production Deployment Requirements
-
-## Status entering deployment
-
-```yaml
-code_development: COMPLETED
-repository_commit: NOT_CREATED
-production_deployment: NOT_STARTED
-reason_repository_commit_missing:
-  current ChatGPT GitOps runtime has AIOS_GITOPS_WRITES_ENABLED=false
-```
-
-The code bundle is an input artifact. The Agent must place it on a non-main
-integration branch, review it, run acceptance tests, merge it through protected
-main and deploy the API adapter. The Agent must not regenerate or materially
-rewrite the supplied implementation without recording the new diff and tests.
-
-## Frozen production state
-
-Before any change, verify:
-
-```yaml
-main_oid: 875d41c3101093149414292067fd700dc214d4d3
-
-V2R1C5:
-  tag_oid: 9e65bd59baea392294c0f253046d3ab116f63145
-  peeled_target_oid: aa60e891547abd7e215af7cf2bf3f21fd23541da
-  baseline_version: V2R1C5
-  baseline_status: PRODUCTION_DEPLOYED

-  evidence_closure_oid: 5e2cf8276f5093f3352b9a3252c701a44c5ab807
-```
-
-If authoritative `main` no longer equals the approved base OID, stop with
-`MANUAL_OWNER_REVIEW_REQUIRED / AUTHORIZED_BASE_OID_DRIFT`. Do not silently
-rebase the bundle onto a different base.
-
-## Bootstrap sequence — no additional Owner interaction
-
-Use the following order so that the approved V2R1C6 base OID remains valid and
-the bridge does not create its own authorization deadlock:
-
-1. Verify the supplied archive/patch SHA-256.
-2. Install the bundle into a temporary root-owned staging directory outside the
-   Git worktrees.
-3. Start a localhost-only temporary instance of
-   `aios_authorized_task_writer_api.py` on a dedicated port or Unix socket.
-4. Bind it to the existing authenticated Owner registry and the exact
-   `writer:provision` scope. Do not expose it through the public gateway.
-5. Execute the live V2R1C6 provisioning request while `main` still equals
-   `875d41c3101093149414292067fd700dc214d4d3`.
-6. Verify `READY_FOR_CODE_AUTHORING`, the exact branch OID, writer scope and
-   negative policy tests.
-7. Use the newly created scoped writer to commit this reviewed bundle onto:
-   `agent/v2r1c6-mainline-reconciliation-20260805`.
-8. Stop and remove the temporary bootstrap service and revoke its temporary
-   runtime credential. Preserve its signed grant receipt and audit logs.
-9. Open a protected PR from the V2R1C6 branch. Deploy the permanent bridge only
-   from the reviewed merge commit.
-
-The temporary service is a control-plane bootstrap, not a production release.
-It must retain:
-
-```yaml
-listen_scope: localhost_only
-production_change_authorized: false
-tag_change_authorized: false
-baseline_change_authorized: false
-main_write_authorized: false
-```
-
-This order avoids asking the Owner to approve a second base OID merely because
-the bridge implementation itself advanced `main`.
-
-### Alternative platform-maintenance path
-
-If policy prohibits a temporary localhost bootstrap service, use an existing
-Owner-approved platform-maintenance executor to create:
-
-```yaml
-branch: patch/owner-authorization-writer-bridge-20260806
-base_ref: refs/heads/main
-base_oid: 875d41c3101093149414292067fd700dc214d4d3
-direct_main_push: false
-force_push: false
-tag_write: false
-baseline_write: false
-production_deploy_during_integration: false
-```
-
-Merging that branch before V2R1C6 provisioning changes the authoritative base
-OID. In that alternative only, a new exact Owner base-OID amendment is required.
-The Agent must never substitute the newer `main` OID automatically.
-
-## Files to install on the branch
-
-Copy with the same relative paths:
-
-```text
-active-runtime/app/authorized_task_writer_provisioning.py
-active-runtime/app/aios_authorized_task_writer_api.py
-docs/gitops/authorized-task-writer-provisioning.md
-docs/gitops/openapi-authorized-task-writer-fragment.yaml
-deploy/systemd/aios-gitops-model-api-authorized-writer-bridge.conf.example
-scripts/smoke_authorized_task_writer_provisioning.py
-tests/test_authorized_task_writer_provisioning.py
-```
-
-Merge the OpenAPI fragment into:
-
-```text
-docs/gitops/openapi-chatgpt-actions.yaml
-```
-
-The final schema must expose:
-
-```yaml
-operationId: provisionAuthorizedTaskWriter
-path: POST /api/task-writer/provision-authorized
-x-openai-isConsequential: true
-```
-
-Do not deploy the fragment as a second standalone OpenAPI document.
-
-## Required review of existing API integration
-
-The adapter expects the existing API handler to provide:
-
-```python
-handler.need(scope)
-handler.body()
-handler.sendj(value, status=200)
-api.H.do_POST
-api.main()
-```
-
-Confirm these contracts against the branch before merge. If the live API has a
-different authentication object shape, make the smallest adapter-only change
-and rerun every test. The core provisioning policy must remain unchanged.
-
-The API authorization registry must grant `writer:provision` only to the
-authenticated Owner role. Agents and ordinary writer tokens must not receive
-this scope.
-
-## Privilege boundary
-
-The API service must remain non-root.
-
-Install a root-owned sudoers rule that allows the API service identity to run
-only these exact commands with `sudo -n --`:
-
-```text
-/usr/local/libexec/aios-grant-signer-adapter
-/usr/local/libexec/aios-grant-validator
-/usr/local/libexec/aios-task-writer-provisioner
-```
-
-Do not allow:
-
-```text
-/bin/sh
-/bin/bash
-/usr/bin/env
-/usr/bin/git
-wildcard executable paths
-SETENV
-arbitrary environment preservation
-```
-
-The governed tools themselves must validate their `--grant-dir` and
-`--result-json` paths. Their binaries must be root-owned, non-symlink, regular,
-executable and not group/world writable.
-
-The signer must access its private signing material only through a runtime
-secret reference. No signing key or token may enter Git, API output, the
-provisioning receipt or systemd environment text.
-
-## Runtime paths and permissions
-
-Create:
-
-```text
-/var/lib/aios-gitops/authorized-writer-bridge
-/var/lib/aios-gitops/authorized-writer-bridge/receipts
-/var/lib/aios-gitops/authorized-writer-bridge/locks
-```
-
-Required properties:
-
-```yaml
-owner: API service identity
-mode: "0700"
-symlink: false
-persistent: true
-```
-
-The directory contains redacted receipts only. Temporary signed grant
-directories are deleted after success or failure.
-
-## Required staging environment
-
-Configure the API service:
-
-```text
-AIOS_GITOPS_REPOSITORY_IDENTITY=aios/aios
-AIOS_GITOPS_AUTHORITY_GIT_DIR=/data/aios-gitops/repo.git
-AIOS_GITOPS_AUTHORIZED_WRITER_STATE_ROOT=/var/lib/aios-gitops/authorized-writer-bridge
-AIOS_GITOPS_GRANT_SIGNER_ADAPTER=/usr/local/libexec/aios-grant-signer-adapter
-AIOS_GITOPS_GRANT_VALIDATOR=/usr/local/libexec/aios-grant-validator
-AIOS_GITOPS_TASK_WRITER_PROVISIONER=/usr/local/libexec/aios-task-writer-provisioner
-AIOS_GITOPS_OWNER_PROVISION_SCOPE=writer:provision
-AIOS_GITOPS_GOVERNED_USE_SUDO=true
-AIOS_GITOPS_SUDO_PATH=/usr/bin/sudo
-```
-
-Use `aios_authorized_task_writer_api.py` as the API entrypoint. It delegates
-all pre-existing routes and adds only the new endpoint.
-
-## Pre-merge tests
-
-Run from the repository root:
-
-```bash
-python3 -m unittest -v tests/test_authorized_task_writer_provisioning.py
-python3 scripts/smoke_authorized_task_writer_provisioning.py
-python3 -m py_compile \
-  active-runtime/app/authorized_task_writer_provisioning.py \
-  active-runtime/app/aios_authorized_task_writer_api.py
-```
-
-Required result:
-
-```yaml
-unit_tests:
-  total: 9
-  failures: 0
-  errors: 0
-smoke: PASS
-py_compile: PASS
-```
-
-Also run all existing GitOps API and isolated writer tests affected by:
-
-```text
-aios_chatgpt_actions_api
-aios_isolated_writer_api
-isolated_writer_authz
-isolated_writer_token_registry
-single_owner_governance
-OpenAPI schema validation
-```
-
-Any regression blocks merge.
-
-## Staging API acceptance
-
-### Negative authentication
-
-An Agent or non-Owner credential calling the endpoint must receive:
-
-```yaml
-http_status: 403
-error: OWNER_AUTHORIZATION_REQUIRED
-```
-
-### Negative scope tests
-
-Requests enabling any of the following must be denied before signer execution:
-
-```text
-production_change_authorized=true
-tag_change_authorized=true
-baseline_change_authorized=true
-main_write_authorized=true
-allowed_operations containing tag/main/baseline/admin operations
-missing required denied operation
-one_time_use=false
-expiry over 1800 seconds
-```
-
-### Drift and conflict tests
-
-Verify:
-
-```yaml
-wrong_base_oid:
-  http_status: 409
-  error: AUTHORIZED_BASE_OID_DRIFT
-
-existing_unreceipted_target_branch:
-  http_status: 409
-  error: EXISTING_BRANCH_OID_CONFLICT
-```
-
-### Governed tool failures
-
-Independently inject and verify fail-closed behavior for:
-
-```text
-signer unavailable
-signer signature absent
-validator signature_valid=false
-validator signer_trusted=false
-validator plan expired
-provisioner grant_consumed=false
-provisioner writer scope enables main/tag/baseline/force push
-any required negative policy test false
-```
-
-None may create or modify a Git ref.
-
-## Live V2R1C6 provisioning request
-
-After protected merge and API deployment, authenticate as the Owner and submit
-exactly:
-
-```json
-{
-  "task_id": "V2R1C6_TASK_SCOPED_WRITER_PROVISIONING",
-  "repository": "aios/aios",

-    "production_deploy",
-    "production_marker_write",
-    "history_rewrite"
-  ]
-}
-```
-
-This request must be executed by the localhost-only bootstrap instance before
-the bridge code advances `main`. The endpoint must never infer “current main”.
-
-If the Agent chooses the alternative merge-first path, it must stop after the
-merge and obtain an exact Owner amendment for the new merge OID. It must not
-silently replace the approved OID.
-
-## Success response
-
-Require:
-
-```yaml
-status: READY_FOR_CODE_AUTHORING
-grant_consumed: true
-branch: agent/v2r1c6-mainline-reconciliation-20260805
-branch_oid: <exact amended authorized base OID>

-    - POST /api/commit-file
-  allow_main_write: false
-  allow_tag_write: false
-  allow_baseline_write: false
-  allow_force_push: false
-```
-
-All seven negative policy results must be true.
-
-Submit the identical request a second time. It must return the same grant and
-branch attestation with:
-
-```yaml
-idempotent: true
-```
-
-It must not run the provisioner again.
-
-## Production postchecks
-
-After API deployment and writer provisioning, independently verify:
-
-```yaml
-existing_routes_regression: PASS
-new_endpoint: PASS
-main_ref: expected reviewed merge commit
-V2R1C5_tag_oid: 9e65bd59baea392294c0f253046d3ab116f63145

-V2R1C5_baseline_unchanged: true
-new_release_tag_created: false
-production_baseline_changed: false
-```
-
-The deployment of this control-plane bridge does not authorize a V2R1C6
-production release. It only enables scoped code authoring.
-
-## Rollback
-
-If the new API route fails:
-
-1. Stop accepting new provisioning calls.
-2. Restore the previous API entrypoint.
-3. Restart and verify all existing routes.
-4. Preserve receipts and logs.
-5. Revoke any task writer capability already minted.
-6. Do not delete a branch or rewrite a tag.
-7. Revert the protected-main bridge commit through an ordinary reviewed revert
-   PR if source rollback is required.

-# Agent Deployment Requirements: Owner Authorization Broker V2
-
-## Objective
-
-Deploy the audited Owner Authorization Broker that closes the bootstrap gap
-without issuing a new general-purpose Owner credential and without modifying
-`/data/aios-gitops/runtime/secrets/gitops.tokens`.
-
-The broker reuses one existing, non-wildcard Owner credential only to
-authenticate the Owner identity through one pre-existing exact scope. It then
-records an immutable task authorization event and directly invokes the
-existing signed grant -> validator -> one-shot provisioner chain.
-
-Production deployment of V2R1C6 is **not** authorized by this task.
-
-## Fixed bindings
-
-```yaml
-task_id: V2R1C6_TASK_SCOPED_WRITER_PROVISIONING
-repository: aios/aios
-base_ref: refs/heads/main
-base_oid: 875d41c3101093149414292067fd700dc214d4d3
-target_branch: agent/v2r1c6-mainline-reconciliation-20260805
-production_change_authorized: false
-tag_change_authorized: false
-baseline_change_authorized: false
-main_write_authorized: false
-```
-
-The existing V2R1C5 objects are frozen:
-
-```yaml
-tag_oid: 9e65bd59baea392294c0f253046d3ab116f63145
-peeled_target_oid: aa60e891547abd7e215af7cf2bf3f21fd23541da
-baseline_version: V2R1C5
-baseline_status: PRODUCTION_DEPLOYED
-```
-
-## 1. Package verification
-
-Verify `MANIFEST.sha256` before installation. Reject any mismatch.
-
-Run:
-
-```bash
-python3 -m unittest -v \
-  tests/test_authorized_task_writer_provisioning.py \
-  tests/test_owner_authorization_broker.py
-
-python3 scripts/smoke_authorized_task_writer_provisioning.py
-python3 scripts/smoke_owner_authorization_broker.py
-python3 -m py_compile \
-  active-runtime/app/authorized_task_writer_provisioning.py \
-  active-runtime/app/aios_authorized_task_writer_api.py \
-  active-runtime/app/owner_authorization_broker.py \
-  active-runtime/app/aios_owner_authorization_broker_api.py
-```
-
-All checks must pass.
-
-## 2. Existing Owner credential selection
-
-Read only the non-secret registry metadata. Select one existing credential
-that satisfies all of the following:
-
-```yaml
-role: owner
-wildcard_scope: false
-account: exact known Owner identity
-contains_exact_intake_scope: true
-```
-
-Use one existing exact scope such as `commit:create` or `file:write`. Prefer
-the narrowest scope already assigned to the intended Owner.
-
-Do not:
-
- use the historical wildcard Owner credential;
- add `writer:provision` to any bearer token;
- create or modify a bearer credential;
- print, copy or commit bearer-token material.
-
-Record only:
-
-```yaml
-owner_account: <non-secret account>
-credential_id: <non-secret ID, when available>
-intake_scope: <one exact existing scope>
-scope_readback_available: true|false
-```
-
-If `handler.need()` returns the exact scope set, configure the Owner account
-allowlist and leave the credential ID allowlist empty.
-
-If scope metadata is not returned, configure the exact non-secret credential
-ID allowlist. If neither exact scope metadata nor a stable non-secret
-credential ID can be proven, stop:
-
-```yaml
-STATUS: BLOCKED
-REASON: OWNER_CREDENTIAL_SCOPE_NOT_PROVABLE
-```
-
-## 3. Staging installation
-
-Install the four application modules in a root-owned staging directory:
-
-```text
-authorized_task_writer_provisioning.py
-aios_authorized_task_writer_api.py
-owner_authorization_broker.py
-aios_owner_authorization_broker_api.py
-```
-
-The directory and files must not be group/world writable.
-
-Prepare environment values:
-
-```yaml
-AIOS_GITOPS_OWNER_AUTHORIZATION_BROKER_ENABLED: "true"
-AIOS_GITOPS_OWNER_AUTHORIZATION_INTAKE_SCOPES: <one exact existing scope>
-AIOS_GITOPS_OWNER_AUTHORIZATION_ALLOWED_IDENTITIES: <exact owner account>
-AIOS_GITOPS_OWNER_AUTHORIZATION_ALLOWED_CREDENTIAL_IDS: <exact ID or empty>
-AIOS_GITOPS_OWNER_AUTHORIZATION_MAX_EXPIRY_SECONDS: "900"
-AIOS_GITOPS_OWNER_AUTHORIZATION_STATE_ROOT:
-  /var/lib/aios-gitops/owner-authorization-broker
-```
-
-Use the existing signer, validator and provisioner paths. Do not change their
-root governance configuration or disable signature checks.
-
-Start a localhost-only staging instance on a temporary port. Do not replace
-the production service yet.
-
-## 4. Authentication fail-closed tests
-
-The staging endpoint is:
-
-```text
-POST /api/governance/owner-authorizations
-```
-
-Required tests:
-
-```yaml
-unauthenticated:
-  expected: 401
-
-wrong_role:
-  expected: 403
-
-wrong_scope:
-  expected: 403
-

-  allow_baseline_write: false
-  allow_force_push: false
-```
-
-## 6. Independent post-provisioning verification
-
-Verify the Authority ref:
-
-```bash
-git --git-dir=/data/aios-gitops/repo.git rev-parse \
-  refs/heads/agent/v2r1c6-mainline-reconciliation-20260805
-```
-
-It must equal:
-
-```text
-875d41c3101093149414292067fd700dc214d4d3
-```
-
-Verify `main` remains unchanged, V2R1C5 tag object and peeled target remain
-unchanged, and the Production Baseline remains V2R1C5.
-
-Verify the broker audit event under:
-
-```text
-/var/lib/aios-gitops/owner-authorization-broker/events/
-```
-
-Requirements:
-
-```yaml
-status: CONSUMED
-wildcard_scope_used: false
-grant_consumed: true
-permissions:
-  directory: "0700"
-  json_files: "0600"
-```
-
-Do not return bearer-token material in the report.
-
-## 7. Commit the broker through the new writer
-
-After `READY_FOR_CODE_AUTHORING`, use only the writer's
-`POST /api/commit-file` route to put this code bundle on:
-
-```text
-agent/v2r1c6-mainline-reconciliation-20260805
-```
-
-Commit the bridge and broker as separate intentional commits when practical:
-
-1. Owner-authorized task-writer bridge.
-2. Audited Owner authorization broker and deployment docs.
-
-Do not merge to `main` directly. Create a protected PR after branch commits
-and tests are complete.
-
-## 8. Permanent service deployment
-
-Only after protected review and merge:
-
-1. Install the reviewed files from the merge commit.
-2. Apply a reviewed systemd drop-in based on the provided example.
-3. Start the wrapper entrypoint:
-   `aios_owner_authorization_broker_api.py`.
-4. Verify all existing API routes still work.
-5. Verify the broker remains localhost/reverse-proxy constrained as intended.
-6. Re-run authentication and policy tests.
-7. Remove the temporary staging instance.
-
-This permanent bridge deployment does not authorize a V2R1C6 production tag,
-Baseline update or application deployment.
-
-## 9. Fail-closed conditions
-
-Stop with `BLOCKED` for any of the following:
-
- Authority `main` no longer equals the fixed base OID.
- Target branch exists at a different OID.
- Only a wildcard Owner credential can authenticate.
- Exact credential scope cannot be proven.
- Owner identity is not explicitly allow-listed.
- Signer, validator or provisioner self-test fails.
- Grant is not marked one-time and consumed.
- Writer allows main, tag, Baseline, force-push or branch-delete operations.
- Audit event contains sensitive material.
- V2R1C5 tag or Baseline changes.

-# Agent execution requirements: V2R1C6 task identity overlay
-
-## Required result
-
-The Agent must return one of:
-
- `READY_FOR_CODE_AUTHORING`
- `BLOCKED`
- `FAILED`
-
-The Agent may not report success until the task branch, isolated worktree and
-task writer are independently verified.
-
-This stage is **not** a production deployment. It must not modify `main`,
-V2R1C5, tags, Registry, Production Baseline or production services.
-
-## Fixed authority
-
-```yaml
-task_id: V2R1C6_TASK_SCOPED_WRITER_PROVISIONING
-repository: aios/aios
-base_ref: refs/heads/main
-base_oid: 875d41c3101093149414292067fd700dc214d4d3

-maximum_ttl_seconds: 900
-production_change_authorized: false
-tag_change_authorized: false
-baseline_change_authorized: false
-main_write_authorized: false
-```
-
-## 1. Verify package
-
-Verify the externally supplied package against the published SHA-256 values and
-then verify every entry in `MANIFEST.sha256`.
-
-Do not synthesize a missing archive. Use either the verified ZIP or TAR.GZ.
-
-Required checks:
-
-```yaml
-package_hash_match: true
-manifest_entries_match: true
-unit_tests_pass: true
-smoke_tests_pass: true
-py_compile_pass: true
-```
-
-## 2. Create root-owned staging
-
-Extract to a fresh directory such as:
-
-```text
-/var/lib/aios-gitops/staging/v2r1c6-task-identity-overlay-<nonce>
-```
-
-Requirements:
-
-```yaml
-owner: root
-group: root
-directory_mode: "0700"
-files_not_world_writable: true
-symlinks_rejected: true
-```
-
-Do not overwrite the active runtime tree.
-
-## 3. Re-run target-host tests
-
-From the staging root:
-
-```bash
-python3 -m unittest discover -s tests -v
-python3 scripts/smoke_authorized_task_writer_provisioning.py
-python3 scripts/smoke_owner_authorization_broker.py
-python3 scripts/smoke_task_identity_overlay.py
-python3 -m py_compile \
-  active-runtime/app/authorized_task_writer_provisioning.py \

-  active-runtime/app/aios_task_identity_overlay_cli.py \
-  scripts/call_task_identity_overlay.py
-```
-
-Any failure is `BLOCKED`; do not proceed.
-
-## 4. Prestart Git and production freeze checks
-
-Read from the authority repository:
-
-```bash
-git --git-dir=/data/aios-gitops/repo.git rev-parse refs/heads/main
-git --git-dir=/data/aios-gitops/repo.git \
-  show-ref --verify --quiet \
-  refs/heads/agent/v2r1c6-mainline-reconciliation-20260805

-target_branch_exists: false
-V2R1C5_tag_oid: 9e65bd59baea392294c0f253046d3ab116f63145
-V2R1C5_peeled_target: aa60e891547abd7e215af7cf2bf3f21fd23541da
-```
-
-Read Baseline and require:
-
-```yaml
-version: V2R1C5
-status: PRODUCTION_DEPLOYED
-target_oid: aa60e891547abd7e215af7cf2bf3f21fd23541da
-evidence_closure_oid: 5e2cf8276f5093f3352b9a3252c701a44c5ab807
-```
-
-If `main` has drifted, return:
-
-```yaml
-STATUS: MANUAL_OWNER_REVIEW_REQUIRED
-REASON: AUTHORIZED_BASE_OID_DRIFT
-```
-
-If the target branch already exists at another OID, return:
-
-```yaml
-STATUS: MANUAL_OWNER_REVIEW_REQUIRED
-REASON: EXISTING_BRANCH_OID_CONFLICT
-```
-
-Do not delete, reset or force-push the branch.
-
-## 5. Discover active secret references
-
-The overlay does not read or modify `gitops.tokens`, but its issuer must compare
-the new random secret against all active bearer secret references.
-
-Discover references without printing secret contents. At minimum include the
-currently active ChatGPT/GitOps bearer secret reference and any other bearer
-files consumed by the active API.
-
-Pass them as a comma-separated list in:
-
-```text
-AIOS_GITOPS_IDENTITY_OVERLAY_COLLISION_SECRET_REFS
-```
-
-Evidence must contain only paths and SHA-256 match counts, not token values.
-
-If active secret references cannot be enumerated, return:
-
-```yaml
-STATUS: BLOCKED
-REASON: ACTIVE_SECRET_REFERENCE_SET_UNRESOLVED
-```
-
-## 6. Install the transient systemd service
-
-Use the provided template:
-
-```text
-deploy/systemd/aios-v2r1c6-task-identity-overlay.service.example
-```
-
-Substitute only:
-
- verified root-owned staging directory;
- verified active secret-ref path list.
-
-Do not change task ID, repository, base OID, target branch or denied
-capabilities.
-
-The service must listen only on:
-
-```text
-127.0.0.1:19864
-```
-
-Before start, run:
-
-```bash
-systemd-analyze verify \
-  /etc/systemd/system/aios-v2r1c6-task-identity-overlay.service
-```
-
-Then:
-
-```bash
-sudo systemctl daemon-reload
-sudo systemctl start aios-v2r1c6-task-identity-overlay.service
-```
-
-Confirm:
-
-```bash
-curl --fail --silent http://127.0.0.1:19864/healthz
-```
-
-Expected:
-
-```yaml
-service: aios-task-identity-overlay
-status: active
-global_token_registry_used: false
-loopback_only: true
-```
-
-Do not expose the port externally.
-
-## 7. Issue the one-time overlay
-
-Use the root-only CLI. The authorization assertion is an audit label for this
-already approved Owner task; it must not be described as an external signed
-event.
-
-Example:
-
-```bash
-sudo env \
-  PYTHONPATH=<staging>/active-runtime/app \
-  AIOS_GITOPS_IDENTITY_OVERLAY_STATE_ROOT=/var/lib/aios-gitops/task-identity-overlays \
-  AIOS_GITOPS_IDENTITY_OVERLAY_SECRET_ROOT=/run/aios-gitops/task-identity-overlays \
-  AIOS_GITOPS_IDENTITY_OVERLAY_TASK_ID=V2R1C6_TASK_SCOPED_WRITER_PROVISIONING \
-  AIOS_GITOPS_IDENTITY_OVERLAY_OWNER_IDENTITY=aiman \
-  AIOS_GITOPS_IDENTITY_OVERLAY_BASE_REF=refs/heads/main \
-  AIOS_GITOPS_IDENTITY_OVERLAY_BASE_OID=875d41c3101093149414292067fd700dc214d4d3 \
-  AIOS_GITOPS_IDENTITY_OVERLAY_TARGET_BRANCH=agent/v2r1c6-mainline-reconciliation-20260805 \
-  AIOS_GITOPS_IDENTITY_OVERLAY_COLLISION_SECRET_REFS=<verified-secret-ref-list> \
-  python3 <staging>/active-runtime/app/aios_task_identity_overlay_cli.py \
-    issue \
-    --ttl-seconds 900 \
-    --authorization-assertion-ref owner-session:V2R1C6:approved-20260806 \
-    --operator-identity <audited-agent-identity> \
-    --result-json /run/aios-gitops/v2r1c6-overlay-issued.json
-```
-
-The result must contain:
-
-```yaml
-status: OVERLAY_ACTIVE
-idempotent: false
-overlay_id: present
-secret_ref: under /run/aios-gitops/task-identity-overlays
-expires_at: within 900 seconds
-```
-
-It must not contain a token.
-
-Verify:
-
-```yaml
-secret_file_mode: "0600"
-metadata_contains_raw_token: false
-token_hash_unique_across_configured_secret_refs: true
-```
-
-## 8. Negative tests
-
-Before the valid request:
-
-1. No Authorization header must return HTTP 401.
-2. A random wrong bearer must return HTTP 401.
-3. A request with `production_change_authorized=true` must be rejected.
-4. A request with another base OID or branch must be rejected.
-5. The valid overlay must remain `ACTIVE` after pre-auth request-validation
-   failures.
-
-Do not use the global Owner or ChatGPT bearer credential for this endpoint.
-
-## 9. Send the valid request
-
-Use:
-
-```text
-deploy/v2r1c6-task-writer-authorization-request.json
-```
-
-Use the provided client so the bearer is not placed in argv, shell history or
-logs:
-
-```bash
-sudo python3 <staging>/scripts/call_task_identity_overlay.py \
-  --secret-ref <secret_ref_from_issue_result> \
-  --request-json <staging>/deploy/v2r1c6-task-writer-authorization-request.json \
-  --url http://127.0.0.1:19864/api/governance/owner-authorizations \
-  --result-json /var/lib/aios-gitops/v2r1c6-overlay-provision-result.json
-```
-
-Required result:
-
-```yaml
-http_status: 200
-status: READY_FOR_CODE_AUTHORING
-owner_authorization_consumed: true
-grant_consumed: true
-identity_overlay_consumed: true
-identity_overlay_secret_removed: true

-branch_oid: 875d41c3101093149414292067fd700dc214d4d3
-```
-
-The result must not include:
-
- bearer token;
- private key;
- signer secret;
- raw signature;
- credential value.
-
-## 10. Independent acceptance
-
-Verify the branch:
-
-```bash
-git --git-dir=/data/aios-gitops/repo.git \
-  rev-parse refs/heads/agent/v2r1c6-mainline-reconciliation-20260805
-```
-
-It must equal:
-
-```text
-875d41c3101093149414292067fd700dc214d4d3
-```
-
-Verify worktree evidence returned by the provisioner:
-
-```yaml
-branch: agent/v2r1c6-mainline-reconciliation-20260805
-head_oid: 875d41c3101093149414292067fd700dc214d4d3
-detached_head: false
-worktree_clean: true
-writer_status: active
-writes_enabled: true
-allowed_routes:
-  - POST /api/commit-file
-allow_main_write: false
-allow_tag_write: false
-allow_baseline_write: false
-allow_force_push: false
-```
-
-Run policy negative tests against the task writer and require explicit policy
-denials for:
-
- main write;
- another branch;
- tag create/update;
- Baseline write;
- force push;
- branch delete.
-
-Network errors, 404, 500 and stopped-service failures do not count as policy
-denials.
-
-## 11. Stop and clean up the overlay
-
-After `READY_FOR_CODE_AUTHORING`:
-
-```bash
-sudo systemctl stop aios-v2r1c6-task-identity-overlay.service
-sudo systemctl disable aios-v2r1c6-task-identity-overlay.service || true
-sudo rm -f /etc/systemd/system/aios-v2r1c6-task-identity-overlay.service
-sudo systemctl daemon-reload
-```
-
-Verify:
-
-```yaml
-overlay_listener_stopped: true
-overlay_secret_removed: true
-global_token_registry_unchanged: true
-disabled_owner_record_unchanged: true
-active_chatgpt_bot_record_unchanged: true
-audit_metadata_retained: true
-```
-
-The root-owned staging directory may be retained until the code is committed,
-then removed after checksum-confirmed repository integration.
-
-## 12. Commit the developed code through the task writer
-
-Only after writer acceptance, use `POST /api/commit-file` to commit the
-verified package contents to:
-
-```text
-agent/v2r1c6-mainline-reconciliation-20260805
-```
-
-Commit in reviewable groups:
-
-1. authorized task-writer bridge;
-2. Owner authorization broker;
-3. task identity overlay;
-4. tests, docs, OpenAPI and deployment templates.
-
-Do not include:
-
- package archives;
- runtime tokens;
- `/run` or `/var/lib` state;
- test result files containing host paths;
- secret references containing values;
- generated credentials.
-
-Run the complete 40-test suite from the branch after commits.
-
-## 13. Protected PR
-
-Create a protected PR from:
-
-```text
-agent/v2r1c6-mainline-reconciliation-20260805
-```
-
-to:
-
-```text
-main
-```
-
-The PR must state:
-
- this change closes Owner authorization bootstrap gaps;
- the overlay is localhost-only and one-time;
- the global token registry is not modified;
- no production release is authorized;
- V2R1C5 tag and Baseline remain unchanged.
-
-The Agent must not merge without the repository's normal protected review.

+# AIOS Codex automatic command watcher
+
+The watcher polls the governed `commands/active` queue without a chat trigger. It uses SQLite transactions for exclusive leases, records the exact command digest, rejects contract drift, retries transient failures, dead-letters exhausted work, and resumes from the last durable phase so an end-event retry does not execute a work unit twice.
+
+Commands are JSON documents validated by `schemas/codex-command.schema.json`. `acceptance_probe` is the only built-in action and has no external side effect. Production `codex` work requires an administrator-provisioned absolute executor path; the instruction is passed on standard input, never argv or environment. The executor receives a sanitized environment and must obtain credentials through its approved file or exec provider. If the executor is absent, the task fails closed and follows the retry/dead-letter policy.
+
+The watcher provides at-most-once execution. It writes the `EXECUTING` phase before launching an external executor; if the host dies after an external effect but before a result is durably recorded, recovery does not replay the work and instead dead-letters the ambiguity for human review. Start and end event JSON is persisted before transmission, so response-loss retries reuse the exact event ID and payload and are deduplicated by the Gateway.
+
+Lifecycle evidence is appended to `/var/log/aios-codex-watcher/audit.jsonl` as `CODEX_AUTO_CLAIM`, `TASK_STARTED`, `TASK_EXECUTED`, `TASK_ENDED`, and `EVENT_POSTED`. Inputs, tokens, stdout, and stderr are not logged; only result digests are retained.
+
+Install from a reviewed commit with `sudo scripts/install_aios_codex_watcher.sh`. The installer creates a content-addressed release, atomically updates `current`, writes a receipt, and enables the five-second systemd timer. The existing Gateway inbound token file is referenced in place and never copied.

+# AIOS Orchestrator Gateway v0.2
+
+This component turns the current passive GPT orchestration pattern into a
+durable, unattended loop:
+
+```text
+Gitea/OpenClaw/Codex event
+  -> HTTP event endpoint or polled file inbox
+  -> durable SQLite state machine
+  -> Workspace Agent API trigger
+  -> strict callback decision
+  -> Responses API background fallback and polling
+  -> OpenClaw/Codex dispatch queues
+  -> start/end/result events
+  -> next orchestration cycle
+```
+
+## Reliability mechanisms
+
+The gateway does not depend on one timer, webhook or model call:
+
+- HTTP event ingestion.
+- Periodic file-inbox polling for missed webhooks and offline producers.
+- Local bare-Git ref polling for `main`, governance, patch and result refs.
+- Workspace Agent retries with a stable event `Idempotency-Key`.
+- Workspace Agent callback timeout and Responses API background fallback.
+- Responses status polling until completion or fail-closed terminal status.
+- SQLite optimistic state versions, idempotency records and processing leases.
+- Exponential retry with a maximum retry count and dead-letter state.
+- Same-blocker and maximum-hop guards to stop non-progress loops.
+- A systemd timer runs `--poll-once` as an independent reliability watchdog.
+
+Workspace Agent trigger runs are asynchronous and do not expose a retrievable
+final response. The central Workspace Agent must therefore call the
+`submit_orchestration_decision` action.
+
+## OpenClaw synchronization
+
+Every lifecycle stage is durably written to the OpenClaw synchronization queue:
+
+- `TASK_DISPATCHED`
+- `TASK_STARTED`
+- `TASK_ENDED`
+- `DECISION_APPLIED`
+- `PROJECT_SUMMARY`
+- `PROJECT_COMPLETED`
+
+An optional authenticated OpenClaw HTTP endpoint can receive the same records.
+A failed HTTP delivery remains in the lifecycle retry queue. OpenClaw remains
+the default project-status synchronizer and authoritative progress presenter.
+
+## Agent execution contract
+
+Each dispatched JSON envelope contains:
+
+- exact contract commit;
+- source event;
+- clean base commit;
+- primary and fallback agent;
+- allowed paths;
+- required checks;
+- forbidden operations;
+- completion event callback format.
+
+OpenClaw and Codex must send a `work_unit_started` event before execution and a
+`work_unit_completed`, `work_unit_blocked`, or `work_unit_failed` event when
+they stop. This guarantees that OpenClaw can synchronize every task start,
+finish, and overall project summary.
+
+## Security
+
+- Model and callback credentials are read only from root-owned secret files.
+- Credentials never enter Git, dispatch payloads or logs.
+- The gateway runs as a dedicated unprivileged user.
+- Dispatch and sync paths are protected against traversal and symlink targets.
+- All state changes require the exact contract commit and current state version.
+- Production evidence, credentials and approvals stay fail-closed.
+- Git history operations remain controlled by the committed governance contract.
+
+## Deployment sequence
+
+1. Apply this source bundle to a clean append-only branch.
+2. Run unit, repository, shell, JSON, systemd and Gitleaks checks.
+3. Configure one or both model channels:
+   - published Workspace Agent API channel and Workspace Agent access token;
+   - Responses API key and approved fallback model.
+4. Publish the decision callback as a Workspace Agent action or MCP tool.
+5. Install the service through `scripts/install_aios_orchestrator_gateway.sh`.
+6. Run `scripts/verify_aios_orchestrator_gateway.sh`.
+7. Submit a harmless event and verify:
+   - trigger acceptance;
+   - strict decision callback;
+   - dispatch file;
+   - OpenClaw task-start/task-end/project-summary synchronization;
+   - duplicate idempotency;
+   - polling recovery after suppressing the HTTP webhook.
+
+The installer copies an explicit gateway-only allowlist into a release directory
+named by its SHA-256 digest, atomically updates `/opt/aios-orchestrator-gateway/current`,
+and persists `/var/lib/aios-orchestrator-gateway/install-receipt.json` with the
+current and previous release. `--dry-run` performs source validation and emits
+`AIOS_ORCHESTRATOR_INSTALL_DRY_RUN=PASS` without changing installed state.
+
+Rollback reads that root-owned `0600` receipt, verifies both release directory
+names and `SOURCE_DIGEST` files, coordinates the gateway and poll units, and
+atomically switches `current` to the previous release. Repeating the same
+rollback is a no-op and emits `NOOP_ALREADY_ROLLED_BACK`.
