+# Bridge v2.1 Durable Reconciliation Bootstrap
+
+This is the planning-only bootstrap artifact for
+`TASK-P0-BRIDGE-V21-DURABLE-RECONCILIATION-20260809`.
+
+The task is bound to the exact base commit
+`3f670c387692b8865a10d5b419468d8a0b64d7a4` and the development branch
+`agent/p0-bridge-v21-durable-reconciliation-20260809`.
+
+The first governed commit records the design boundary and acceptance contract
+only. It does not implement the v2.1 body, mutate main, create tags, change
+Baseline, or touch production. Future work must preserve absent-ref CAS,
+observation-first recovery, durable JobStore state, exact Authority/Gitea/API
+reconciliation, and the existing secret-scanning and credential-projection
+boundaries.

+# ChatGPT Bridge v2 Control Plane Convergence Design
+
+Date: 2026-08-09  
+Task: `TASK-P0-CHATGPT-BRIDGE-V2-CONTROL-PLANE-CONVERGENCE-20260809`  
+Repository: `aios/aios`  
+Approved development base: `2e8fa22989808a448065d1d76b5b18948774a637`  
+Target branch: `agent/p0-chatgpt-bridge-v2-control-plane-convergence-20260809`
+
+## Scope and authority
+
+This design converges the ChatGPT GitOps Bridge, the existing Authorized Task Writer, the continuation lease protocol, the Durable GitOps Job Controller, and immutable control-plane runtime identity.
+
+The development base is exact and must never be replaced with a dynamically resolved `HEAD`, `latest`, or `main`. If Authority `refs/heads/main` differs from the approved OID before the first governed writer push, execution fails with `BASE_OID_CHANGED`.
+
+This task does not authorize production changes. The following remain immutable:
+
+- Production Baseline `V2R1C7`.
+- Production target OID `c7adece1cc8beffe7c718d53c775898b45d6c7f8`.
+- Production tag OID `82792347937c0df59a8e02d6162775252bcad2e2`.
+- Production Registry, services, deployment state, runtime, tags, and release evidence.
+- Authority `main`.
+
+Force push, history rewrite, direct main push, production mutation, tag mutation, baseline mutation, and secret commits are always denied.
+
+## Immutable control-plane runtime identity
+
+A control-plane release is installed into a versioned immutable directory equivalent to:
+
+```text
+/opt/aios/gitops-control-plane/<release-id-or-oid>/
+```
+
+The release manifest binds:
+
+```text
+control_plane_release_version
+control_plane_target_oid
+artifact_sha256
+runtime_path
+bridge_schema_version
+repository_identity
+authoritative_git_dir
+deployment_state
+```
+
+The validator is independent from the mutable Git workspace. It rejects execution when the runtime path is a workspace/worktree, the observed runtime commit or artifact digest differs from the manifest, the repository identity is not `aios/aios`, the authoritative Git directory is absent or mismatched, or the Bridge schema version is absent or unsupported.
+
+Every failure is fail closed with `CONTROL_PLANE_RUNTIME_DRIFT`. No fallback to a mutable workspace is permitted. The installer and systemd template are staging-safe; this task may install and restart only a staging/test service.
+
+## Bridge v2 adapter
+
+The Bridge schema identity is `aios.chatgpt-gitops-bridge.v2`. It is independent from the production baseline, control-plane release version, and runtime release commit.
+
+The Bridge exposes:
+
+- `getRuntimeStatus`
+- `getGovernedWriteCapabilities`
+- `createGovernedTask`
+- `acquireWriterLease`
+- `commitFileGoverned`
+- `commitFilesGoverned`
+- `getGitOpsJob`
+- `resumeGitOpsJob`
+- `reconcileGitOpsJob`
+
+The adapter reuses existing mechanisms and does not create a second writer, lease protocol, branch state store, job database, or direct Git mutation path.
+
+## Governed task and lease flow
+
+`createGovernedTask` binds an exact task ID, repository, approved base OID, non-main branch, risk, and description. Existing branches are read back and bound to their observed full OID. Idempotent replay returns the original binding; conflicting replay fails closed.
+
+`acquireWriterLease` uses `WriterLeaseRequestV2`. Continuation uses:
+
+```text
+branch_mode=CONTINUE_EXISTING
+expected_branch_oid=<full OID>
+generation=<monotonic integer>
+create_target_branch=false
+worktree_mode=detached_at_expected_head
+cas_ref_update_required=true
+```
+
+Credentials remain server-side and never appear in responses, Git, durable job metadata, or logs.
+
+## Governed commit flow
+
+`commitFileGoverned` and `commitFilesGoverned` submit work to the existing `GitOpsJobController` and `JobStore`. The server computes payload digests. Raw file content is stored only in the content-addressed payload domain. Secret scanning, protected-path policy, repository binding, lease validation, and branch authorization run before side effects.
+
+`commitFilesGoverned` is one atomic Git commit and enforces bounded file count, per-file size, and total payload size. Any failure leaves no partial commit or ref update.
+
+All ref updates use compare-and-swap. Stale `expected_branch_oid` returns conflict and never triggers automatic rebase. After push, Authority and remote Gitea refs are independently read and must equal the resulting commit OID.
+
+## Durable job lifecycle
+
+Job reads return only non-sensitive metadata: `job_id`, `state`, `revision`, `side_effect_state`, `retryable`, `binding`, and `receipt_summary`.
+
+Terminal jobs cannot be changed by ordinary resume. Resume requires `job_id` and `expected_revision` and uses revision CAS. Reconciliation is observation-first: for `UNKNOWN`, `RECONCILIATION_REQUIRED`, or `REMOTE_PUSH_PENDING`, local, Authority, and remote refs are read before state changes. A blind repeated push is never reconciliation.
+
+## Legacy behavior
+
+Legacy writes remain disabled while governed writes are enabled:
+
+```text
+legacy_writes_enabled=false
+governed_writes_enabled=true
+```
+
+The global `AIOS_GITOPS_WRITES_ENABLED` flag is never enabled as the solution. Legacy operations remain temporarily visible for compatibility and diagnostics, but return:
+
+```json
+{
+  "error": "LEGACY_WRITE_DISABLED",
+  "replacement": "createGovernedTask",
+  "governed_writes_available": true
+}
+```
+
+## OpenAPI convergence
+
+`docs/gitops/openapi-chatgpt-actions.yaml` is the canonical Bridge v2 schema and integrates the Authorized Task Writer fragment. The canonical CAS field is `expected_branch_oid`. `expected_head_oid` may be accepted only at an explicit deprecated adapter boundary.
+
+Contract tests require exact equality between OpenAPI required fields, runtime parser required fields, and generated GPT Action schema required fields.
+
+## Acceptance
+
+Automated coverage includes runtime path/OID/digest/repository drift, exact task/branch/OID/lease/CAS behavior, job DB failure, restart during remote verification, remote timeout, response loss after remote success, idempotency replay/conflict, concurrent branch movement, unauthorized or main branch writes, protected paths, secret-like payloads, disabled governed writer, missing/expired lease, wrong repository identity, and observation-first reconciliation.
+
+The staging sequence is:
+
+```text
+getRuntimeStatus
+getGovernedWriteCapabilities
+createGovernedTask
+acquireWriterLease
+commitFilesGoverned
+getGitOpsJob
+verify Authority branch ref
+verify remote Gitea branch ref
+restart staging control-plane service
+getRuntimeStatus
+acquire continuation lease
+second governed commit
+verify remote ref again
+```
+
+Completion requires all tests, staging restart continuation, Authority/remote OID equality, unchanged production invariants, no force push, no tag rewrite, no direct main push, and no secret commit.
+
+## Implementation boundaries
+
+Implementation is limited to the Bridge, existing writer and job-controller adapters, runtime identity/installer, staging systemd template, OpenAPI documents, tests, and engineering evidence. Hermes Adapter integration and production cutover are outside this task and require separate approval.
