 # 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.
 ## Machine-Readable Result
 ```yaml
 gate: G1
 variant: openclaw-cleanroom
 date: 2026-07-14
 status: PASS
 source_commit: 502ef30642597fb0b70b90ae2e8a0b6af217d80e
 source_branch: origin/work/v2r1-integration-quality-2000

 cleanup_scan: PASS
 secret_scan: PASS
 rollback_status: PASS
 recovery_verified: true
 workspace_clean_at_test_completion: true
 merge_performed: false
 tag_created: false
 baseline_promoted: false
 deployment_performed: false
 ```
 ## 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.

 The machine-readable record is `.agent/results/releases/V2R1C1-BASELINE-CLOSURE.json`. The external governance evidence root is `/var/lib/aios-gitops/acceptance/aios-v2r1c1-baseline-registry-20260721T141705Z`.
 ## 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.
 ## Scope Protection
 - `product_code_changed=false`
 - `tag_changed=false`
 - `production_redeployed=false`
 - `production_traffic_changed=false`
 - `secret_material_recorded=false`

 # 执行 GitOps 独立 Worktree 与统一运行身份迁移
 ```yaml
 task_id: TASK-GITOPS-ISOLATED-WORKTREE-MIGRATION-20260714T233742UTC8
 created_at: 2026-07-14T23:37:42+08:00
 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>

 # 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",
  "base_oid": "875d41c3101093149414292067fd700dc214d4d3",
  "target_branch": "agent/v2r1c6-mainline-reconciliation-20260805",
  "owner_authorization_reference": "chat-owner-authorization:v2r1c6:20260806",
  "one_time_use": true,
  "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",
    "branch_delete",
    "repository_admin",
    "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:
  workspace_role: task-scoped-isolated-writer
  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
 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
 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",
  "base_oid": "875d41c3101093149414292067fd700dc214d4d3",
  "target_branch": "agent/v2r1c6-mainline-reconciliation-20260805",
  "one_time_use": true,
  "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",
    "branch_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
 writer_scope:
  workspace_role: task-scoped-isolated-writer
  writes_enabled: true
  allowed_branch: agent/v2r1c6-mainline-reconciliation-20260805
  allowed_base_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.

 - Grant is not marked one-time and consumed.
 - Writer allows main, tag, Baseline, force-push or branch-delete operations.
 - Audit event contains sensitive material.

 # 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
 owner_identity: aiman
 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/owner_authorization_broker.py \
  active-runtime/app/task_identity_overlay.py \
  active-runtime/app/aios_authorized_task_writer_api.py \
  active-runtime/app/aios_owner_authorization_broker_api.py \
  active-runtime/app/aios_task_identity_overlay_api.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
 git --git-dir=/data/aios-gitops/repo.git rev-parse refs/tags/V2R1C5
 git --git-dir=/data/aios-gitops/repo.git rev-parse 'refs/tags/V2R1C5^{}'
 ```
 Expected:
 ```yaml
 main_oid: 875d41c3101093149414292067fd700dc214d4d3
 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
 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.

 ## Fail-closed conditions
 Return `BLOCKED` and stop on any of:
 - authoritative main OID drift;
 - target branch conflict;
 - inability to enumerate active secret references;
 - secret hash collision;
 - overlay not bound to the exact task/base/branch;
 - non-loopback listener;
 - raw secret in result or logs;
 - Owner Authorization Broker event not created;
 - signer/validator/provisioner failure;
 - grant not consumed;
 - branch OID mismatch;
 - writer exposes main/tag/Baseline/force-push permissions;
 - V2R1C5 tag or Baseline changes.
 Never fall back to the shared `gitops-write-bot.token`, a wildcard credential,
 manual `gitops.tokens` edits or a direct Git ref write.

 """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

 """One-shot local Owner authentication ingress for AIOS.
 This module deliberately does not mint a reusable Owner token.
 Authentication is based on a real local login session:
 - a root-run one-shot server owns a Unix socket;
 - the client must run as the configured Owner OS account;
 - the server validates SO_PEERCRED, Linux audit loginuid and the controlling TTY;
 - the Owner must interactively confirm the exact task/branch/base request;
 - the server constructs a narrow OwnerPrincipal and invokes the existing
  OwnerAuthorizationBroker;
 - one successful authorization consumes the service lifetime.
 The resulting principal is fixed to one non-wildcard intake scope
 (`commit:create` for the current deployment) and cannot carry production,
 tag, baseline, main or history-rewrite capability.
 This is a trust-root ingress, not a Git writer and not a production executor.
