+# 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.
+- 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
+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.

+Durable state is intentionally small so restart recovery and duplicate

+"""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.

+"""One-interaction bootstrap for the AIOS autonomous release campaign.
+
+A single real local `aiman` login confirmation does two things atomically at the
+policy layer:
+
+1. Writes a root-owned, digest-sidecar protected campaign authorization receipt
+   in PENDING_CONTROL_PLANE_MERGE state. It grants no immediate production side
+   effect; the campaign becomes ACTIVE only after the campaign control-plane PR
+   is merged and machine activation verifies lineage and implementation.
+2. Invokes the existing OwnerAuthorizationBroker to issue only the narrow
+   engineering writer needed to implement that control-plane PR.
+
+No reusable Owner token is minted.

+This module resolves bearer-registry identity ambiguity without modifying the

+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.
