-# 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.

-# V2R1 Gate 1 — Clean-Room Final Evidence
-
-## Summary
-
-| Field | Value |
-|---|---|
-| Date | 2026-07-14 |
-| Source commit | `502ef30642597fb0b70b90ae2e8a0b6af217d80e` |
-| Source branch | `origin/work/v2r1-integration-quality-2000` |
-| Result branch | `fix/v2r1-g1-cleanroom-final-evidence-r2-20260714` |
-| Result commit reference | `HEAD` |
-| Gate | `G1` |
-| Variant | `openclaw-cleanroom` |
-| Status | `PASS` |
-
-The immutable report uses `HEAD` for post-commit verification. The resolved commit object ID is recorded by the external acceptance result after this file is committed; a Git commit cannot reliably embed its own object ID because changing the file changes the tree and commit identity.

-## Evidence Provenance
-
-The test, cleanup, secret-scan, rollback, and recovery results below are execution evidence supplied by OpenClaw for the Gate 1 run. This correction commit changes only the evidence report and does not claim that the GitOps API reran the suites.
-
-## HMAC Test-Key Length Verification
-
-| Test file | Variable | Test-only value | Length |
-|---|---|---|---:|
-| `tests/v2r1/test_runtime_wiring.py:24` | `internal_key` | `b"runtime-internal-context-key-is-32bytes"` | 39 bytes |
-| `tests/v2r1/test_runtime_wiring.py:25` | `ingress_key` | `b"runtime-external-ingress-key-is-32bytes"` | 39 bytes |
-
-Both values are test fixtures. The supplied evidence reports that no production secret was introduced.
-

-## Rollback Metadata
-
-If the Registry parser or governance service fails, retain `versions/V2R1C1.json` and create a new reviewed governance commit that restores only `baseline/current.json` and `VERSION` to `V1R4C6`. Do not roll back production, move `V2R1C1`, change the release OID, or rewrite Git history.

-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。
-
-## 10. 结果文件

-# 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
-  target_oid: aa60e891547abd7e215af7cf2bf3f21fd23541da
-  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",
-  "base_ref": "refs/heads/main",

-    "baseline_write",
-    "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>
-base_oid: <same exact OID>
-main_unchanged: true
-
-writer_scope:

-  writes_enabled: true
-  allowed_branch: agent/v2r1c6-mainline-reconciliation-20260805
-  allowed_base_oid: <exact amended authorized base OID>
-  allowed_routes:
-    - 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_peeled_target: aa60e891547abd7e215af7cf2bf3f21fd23541da
-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
-

-  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
-
-wildcard_owner:
-  expected: 403
-  error: WILDCARD_OWNER_CREDENTIAL_REJECTED
-
-unallowlisted_owner:
-  expected: 403
-  error: OWNER_IDENTITY_NOT_ALLOWED
-
-production_capability_true:
-  expected: 403
-  error: PRODUCTION_CAPABILITY_REJECTED
-```
-
-A connection failure, 404 or 500 is not an authorization-policy pass.
-
-## 5. Formal provisioning request
-
-Use the selected existing non-wildcard Owner credential through its runtime
-secret reference. Never place the bearer token in the request body, command
-line, shell history, output report or Git.
-
-Request:
-
-```json
-{
-  "action": "AUTHORIZE_TASK_WRITER_PROVISIONING",
-  "task_id": "V2R1C6_TASK_SCOPED_WRITER_PROVISIONING",
-  "repository": "aios/aios",
-  "base_ref": "refs/heads/main",

-  "expires_in_seconds": 900,
-  "production_change_authorized": false,
-  "tag_change_authorized": false,
-  "baseline_change_authorized": false,
-  "main_write_authorized": false,
-  "allowed_operations": [
-    "create_worktree",
-    "create_target_branch_if_absent",
-    "commit_to_target_branch",
-    "push_target_branch"
-  ],
-  "denied_operations": [
-    "direct_main_push",
-    "force_push",
-    "tag_create",
-    "tag_update",
-    "tag_delete",

-    "repository_admin",
-    "baseline_write",
-    "production_deploy",
-    "production_marker_write",
-    "history_rewrite"
-  ]
-}
-```
-
-The Owner authorization reference is generated by the broker. The caller must
-not submit or invent one.
-
-Expected result:
-
-```yaml
-status: READY_FOR_CODE_AUTHORING
-owner_authorization_event_id: generated
-owner_authorization_reference: generated
-owner_authorization_digest_sha256: generated
-owner_authorization_consumed: true
-approval_plan_id: generated
-grant_digest_sha256: generated
-grant_consumed: true
-
-branch_oid: 875d41c3101093149414292067fd700dc214d4d3

-  allow_main_write: false
-  allow_tag_write: false
-  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
-target_branch: agent/v2r1c6-mainline-reconciliation-20260805

-one_time_use: true
-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: agent/v2r1c6-mainline-reconciliation-20260805
-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

-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.

-"""Audited Owner authorization broker for task-scoped writer provisioning.
-
-The broker closes the bootstrap gap without minting a new general-purpose
-Owner token and without modifying the bearer-token registry. It accepts an
-already-authenticated, explicitly allow-listed Owner principal, records a
-tamper-evident authorization event, and invokes the existing
-AuthorizedTaskWriterProvisioner with a generated authorization reference.
-
-The broker never writes Git refs itself. The governed signer, validator and
-one-shot provisioner remain the only components allowed to create the task
-branch/worktree/writer.

-"""Task-scoped identity overlay for bootstrap writer provisioning.

-This module resolves bearer-registry identity ambiguity without modifying the
-global token registry. A root-governed one-shot issuer creates a random,
-short-lived credential bound to exactly one repository, base OID, task and
-target branch. The HTTP overlay authenticates only that credential and invokes
-the existing OwnerAuthorizationBroker.
-
-The overlay never grants main, tag, baseline, production or repository-admin
-capabilities. The bearer secret is stored only in a root-owned runtime path and
-is removed after success, failure, revocation or expiry.
