+- Target branch: `agent/r42-p0a-taskplane-scope-isolation-20260816`
+- Generation: `1`
+
+The implementation reuses this exact boundary. It does not create a replacement Task, Job, branch, generation, or idempotency key.
+
+## Model and invariants
+
+`TaskPlan` gains first-class `scope_type`, `tenant_id`, `user_id`, `project_id`, `conversation_id`, and `run_id` fields. The fields participate in accepted-key validation, parsing, serialization, persistence, and authorization.
+
+Historical rows without scope data normalize to `scope_type=legacy`; no tenant is inferred. Tenant-scoped tasks require a non-empty `tenant_id`. System/global resources use an explicit `scope_type=system` invariant and do not receive a fabricated tenant. A task may add user, project, conversation, and run ownership within its tenant.
+
+## Trusted ActorContext
+
+TaskPlane defines a small immutable `TaskActorContext` used only for authorization. The HTTP authenticator returns an identity. `PolicyEngine` resolves that identity through server-owned policy configuration into the effective context and capabilities. Request fields such as `tenant_id`, `user_id`, `group_id`, and `role` are declarations only and never expand authority.
+
+Public create, list, and get paths always use the resolved context. Internal compatibility calls may omit a context and retain explicit legacy behavior, but the HTTP adapter never uses that path.
+
+## Persistence
+
+SQLite remains the current runtime. `_create_schema()` performs an idempotent forward migration that adds the six scope columns and indexes, then backfills only missing `scope_type` values to `legacy`.
+
+New writes persist scope in both the canonical `task_json` representation and first-class columns. Reads accept historical JSON without scope, using legacy columns, but reject a new-row mismatch between JSON and columns. SQL list/get predicates are parameterized and applied before row hydration.
+
+PostgreSQL remains a separate migration target and is not claimed by this change.
+
+## Authorization flow
+
+1. HTTP bearer authentication yields an identity.
+2. `PolicyEngine` verifies capability and resolves the identity to `TaskActorContext`.
+3. Create binds the requested scope to the trusted context and rejects mismatches.
+4. List/get pass the trusted context to `TaskPlaneStore`.
+5. Store applies tenant and ownership predicates in SQL; privileged capabilities may explicitly cross scope.
+
+Tenant actors cannot read legacy tasks, another tenant, or mismatched owned resources. Legacy actors can only read legacy tasks. System actors require explicit privileged capability for cross-scope access.
+
+## Failure behavior
+
+Missing tenant scope, forged scope, unknown scope types, JSON/column divergence, and unauthorized list/get operations fail closed with canonical TaskPlane errors. Public get does not reveal whether an out-of-scope task exists.
+
+## Verification
+
+Tests exercise real model round trips, SQLite migration/restart, Service/Policy/Store wiring, tenant A versus tenant B list/get denial, ownership filtering, forged create payload rejection, legacy isolation, privileged access, and SQL parameterization. Existing TaskPlane API, RBAC, recovery/security, and security-contract suites remain mandatory.
+
+The candidate is complete only after real `TASK_CLAIMED`, `TASK_HEARTBEAT`, exact WriterLease, governed commit, OID convergence, result submission, and `TASK_VERIFIED`. Protected main and production remain unchanged.

+# R4.2 P0-C Trace / Tool-MCP / Credential Governance
+
+## Status boundary
+
+This change is a candidate implementation on the governed P0-C branch. It does
+not promote protected `main`, deploy Production, or assert that all R4.2 target
+architecture is complete.
+
+## Scope model
+
+Governance resources use an explicit `scope_type`:
+
+- `tenant` requires `tenant_id` and may narrow to user, project,
+  conversation, and run;
+- `system` and `global` prohibit tenant ownership fields;
+- `legacy` preserves unscoped historical records without inventing ownership.
+
+System and global tools therefore never receive a synthetic tenant merely to
+satisfy a tenant-oriented schema.
+
+## Trace lineage
+
+`TaskPlan` and `MessageEnvelope` scope is bound to a `TraceContext`. The trace
+records `trace_id`, `span_id`, parent span, correlation, causation, task,
+message, and the canonical P0-A scope. Child spans must keep the parent's trace,
+task, and scope. Privileged visibility does not permit cross-scope trace
+splicing.
+
+`MessageEnvelope.correlation_id` is persisted and identity-bound. Existing
+handoff databases are upgraded in place with an idempotent column migration;
+legacy rows retain their prior event IDs because a null correlation field is
+not added to the historical identity material.
+
+Observability keeps its legacy presentation fields, but new governed records
+also carry immutable trace and scope fields. Scoped records require a trusted
+server actor for queries. A repeated execution ID is an idempotent replay only
+when the complete record matches; conflicting overwrites are denied.
+
+## Tool and MCP governance
+
+`ToolDescriptor` binds a tool or MCP server to:
+
+- an explicit resource scope;
+- required actor capabilities;
+- an optional credential reference.
+
+Invocation authorization requires exact propagation of the trace scope and a
+capability superset. Unknown tools, cross-tenant calls, scope substitution, and
+non-privileged access to system/global resources fail closed. Every successful
+registration and invocation appends hash-chained audit evidence.
+
+## Credential governance
+
+Credentials are represented only by references whose schemes are
+`systemd-credential`, `vault`, or `secret-manager`. Raw bearer tokens, passwords,
+and arbitrary values are rejected. Grants are bound to scope, operation, task,
+tool, and expiry. Public/audit records contain a reference hash where disclosure
+is unnecessary; secret material is never persisted by this module.
+
+The existing runtime credential broker remains backward compatible for system
+leases, adds explicit tenant/system/global invariants, and rejects providers
+that attempt to return raw token/secret/password environment values instead of
+file/reference indirection.
+
+## Durable evidence
+
+The SQLite governance store is restart-safe and idempotently initializes four
+tables: governed tools, trace spans, credential grants, and audit evidence.
+Audit entries form a SHA-256 chain. Acceptance requires the chain to verify and
+contain the required actions; missing evidence is not treated as success.
+
+## Acceptance tests
+
+The candidate must pass:
+
+- `TRACE_LINEAGE_CONTINUITY`;
+- `TRACE_SCOPE_MISMATCH_DENY`;
+- `TOOL_MCP_AUTHZ_DENY`;
+- `TOOL_SCOPE_PROPAGATION`;
+- `CREDENTIAL_SCOPE_DENY`;
+- `CREDENTIAL_SECRET_EXPOSURE_DENY`;
+- `AUDIT_EVIDENCE_COMPLETENESS`;
+- P0-A scope and P0-B handoff regression suites;
+- Python compilation, `git diff --check`, and a diff-scoped secret scan.
+
+The repository-wide baseline currently has seven unrelated failures in the
+isolated host environment (five stale continuation-contract fixtures and two
+host-permission fixtures). The same seven failures reproduce at the untouched
+`a642b045775b9154a00ae78543037fbef4fb447b` base; they are not suppressed or
+modified by P0-C.

+# R4.2 P1 — Durable Online Agent Execution
+
+Status: candidate implementation. This document does not imply protected-main promotion or Production deployment.
+
+## State model
+
+The generic worker uses two local durable layers:
+
+1. `tasks/<task_id>.json`: atomic fast-state cache for compatibility and quick restart.
+2. `checkpoints.sqlite3`: append-only attempt/phase journal with `synchronous=FULL`.
+
+Checkpoint identity is bound to:
+
+- task_id
+- attempt
+- execution_digest
+- job_id
+- repository
+- base_oid
+- expected_branch_oid
+- target_branch
+- generation
+
+A checkpoint from another repository/branch/generation is never reused.
+
+Phases are monotonic within an attempt:
+
+`claimed → workspace_prepared → verification_passed → source_capture_done|commit_done → result_pending → result_submitted`
+
+`reconciliation_required` is an explicit recovery phase.
+
+## Attempt-aware result idempotency
+
+Result submission idempotency keys include the official Task attempt and the execution digest. The same
+attempt reuses the same key after a timeout/restart; a later official attempt cannot collide with an
+earlier result.
+
+Before submitting a result the worker durably writes `result_pending`, including the result hash and
+idempotency key. After a successful or exact-idempotency-reconciled API response it writes
+`result_submitted`.
+
+A 409 is accepted only if the Task API already contains the exact same result body and the Task is
+VERIFYING/SUCCEEDED. A conflicting result remains a hard failure.
+
+## Resume rules
+
+- `source_capture_done` and `result_pending` may be reused across later official attempts only when the
+  execution/scope binding is identical. This avoids repeating read-only source capture.
+- A deterministic task that crashed before governed commit replays from a new clean detached worktree.
+  This is safe because there is no external side effect yet.
+- `commit_done` is never recommitted. Recovery requires exact Job receipt OID convergence plus exactly
+  one ACTIVE WriterLease whose `current_head_oid` equals the governed commit.
+- delayed Git visibility remains `RECONCILIATION_REQUIRED`, preserving an explicit recovery entry.
+
+## Crash cleanup
+
+On worker startup, stale `task-*` workspaces under the configured workspace root are removed before
+polling begins. The path boundary is verified before deletion.
+
+## Contracts
+
+P1 gates include:
+
+- CHECKPOINT_DURABLE_WRITE
+- RESUME_FROM_CHECKPOINT
+- RETRY_IDEMPOTENT_NO_DUPLICATE_SIDE_EFFECT
+- CRASH_RECOVERY_CONVERGENCE
+- WORKER_RESTART_RESUME
+- CHECKPOINT_SCOPE_ISOLATION
+- RESULT_SUBMISSION_REPLAY_SAFE
+- WORKSPACE_CLEANUP_RECOVERY
+- LEASE_RENEWAL_RECOVERY
+
+WriterLease and governed Job authority remain in the existing Bridge/GitOps durable stores; the worker
+checkpoint DB is not a competing authority for Git state.

+# R4.2 P2 Agent Fleet / Multi-Agent Scheduling / Fault Isolation
+
+P2 adds a durable fleet decision layer inside TaskPlane without replacing TaskPlane claim/lease
+ownership. Worker registration/heartbeat remains authoritative for liveness. TaskPlane claim CAS
+remains authoritative for ownership. Probe-before-reassignment remains mandatory after an expired
+lease. P1 checkpoint/result replay remains authoritative after worker restart.
+
+`FleetScheduler` adds durable worker capacity slots, weighted scope fairness, starvation aging,
+affinity/anti-affinity labels, worker circuit breakers, per-task/worker quarantine and idempotent
+dispatch reservations. Fleet state is colocated in the existing TaskPlane SQLite database and is
+created idempotently; no new daemon or database is introduced.
+
+A fleet reservation is only a scheduling decision. It does not claim a Task. Callers must perform
+the normal TaskPlane claim and may then bind the returned claim ID to the reservation. This preserves
+the existing ownership and recovery invariants.
+
+Failure recovery never bypasses probe evidence. When TaskPlane recovery places work back in a
+claimable state, P2 may quarantine the failed worker and prefer another worker/failure domain.

+# R4.2 P2 Compact Interface Map Runtime
+
+## Purpose
+
+The persistent Online Agent already supports the canonical read-only `source_capture` action, but
+its `SourceCaptureExecutor` always returns an `aios.engineering.source-snapshot.v2` tar.gz+base64
+payload. That is correct for implementation source transfer, but too large for control-plane
+consumers that only need a bounded implementation map.
+
+P2 adds a new **adapter**, not a new execution action:
+
+```text
+action=source_capture
+adapter=compact_interface_map
+```
+
+This preserves the existing execution-v2 schema and Bridge policy:
+
+- read-only repository;
+- no change set;
+- no verification commands;
+- `writer_lease=false`;
+- no branch or commit;
+- existing capability and execution-digest validation.
+
+## Compact map contract
+
+`aios_online_agent_compact_map.py` scans only approved repository roots and source suffixes. It
+returns:
+
+- at most 40 relevant modules;
+- at most 80 selected Python symbols in total;
+- at most 40 test symbols;
+- at most 25 excerpts;
+- at most 1200 characters per excerpt;
+- SQL table names;
+- systemd unit names;
+- current invariants, failure windows and reuse points;
+- P2 fleet contract-to-surface mappings.
+
+The result is hard-bounded to 120 KiB and contains no source archive or `payload_b64`.
+
+Source excerpts apply a conservative sensitive-pattern redaction before result construction.
+
+## P2 contracts
+
+The map supplies evidence surfaces for:
+
+- `FLEET_AGENT_REGISTRATION`
+- `FLEET_CAPACITY_SCHEDULING`
+- `FLEET_FAIRNESS`
+- `FLEET_FAULT_ISOLATION`
+- `FLEET_WORKER_REASSIGNMENT`
+- `FLEET_SCOPE_ISOLATION`
+- `FLEET_IDEMPOTENT_DISPATCH`
+- `FLEET_FAILURE_RECOVERY`
+
+Missing first-class scheduling/fleet primitives are reported as gaps rather than invented.
+
+## Result
+
+When the adapter is selected, the worker returns:
+
+```text
+status=SUCCEEDED
+classification=P2_INTERFACE_MAP_CAPTURED
+execution_mode=compact_interface_map
+writer_lease=NONE
+```
+
+The existing `source_capture_done` / P1 checkpoint/retry path is reused, so the compact analysis
+inherits attempt-aware result idempotency and restart-safe result submission.
+
+## Governance
+
+This capability is runtime infrastructure only. The implementation candidate may use a governed
+branch/WriterLease for its own code change, but any task executed through `compact_interface_map`
+is read-only and must not create a WriterLease, branch, commit, protected-ref write, or Production
+side effect.

+# R4.2 P2-B Fleet Order Preservation Repair
+
+P2-C live acceptance exposed a real integration defect in the verified P2-B candidate. The fleet
+scheduler correctly produced durable cross-scope fairness order, but the integration passed the
+entire ranked list to the legacy scheduler. The legacy scheduler then applied its own priority /
+created_at / task_id sort and silently discarded fleet ordering.
+
+The repair preserves the legacy scheduler as the fail-closed security oracle while changing how it
+is called: one fleet-ranked candidate is presented at a time. A candidate rejected by legacy
+security/policy advances to the next fleet candidate. A candidate returned by the oracle must have
+the same task ID as the candidate presented, otherwise execution fails closed.
+
+Task ownership remains unchanged: the original schedule_for_worker/claim_task CAS remains
+authoritative, and a fleet reservation is still only bound after the claim succeeds.
+

+P2-B connects the verified P2 fleet primitives to the existing TaskPlane pull scheduler without
+replacing its security or ownership logic.
+
+The integration uses two stages. `FleetScheduler.rank_for_worker()` performs only read-only
+capacity/fairness/fault-isolation ranking. The original `TaskScheduler.next_queued_task()` is then
+run over that ordered list and remains the fail-closed security oracle for worker liveness,
+capabilities, data classification, execution zone and other existing policy checks. Only a task
+accepted by the original scheduler receives a short durable fleet reservation.
+
+The original `TaskScheduler.schedule_for_worker()` remains the sole claim path and continues to call
+the existing TaskPlane `claim_task` CAS. After a successful claim, the claim ID is bound to the
+fleet reservation. A claim error releases the reservation. A fleet reservation is never treated as
+task ownership.
+
+P2-B also makes the reservation capacity check atomic inside the fleet SQLite transaction so two
+concurrent pullers cannot oversubscribe the same worker slot. Circuit and task/worker quarantine
+state are enforced on the real pull path. Explicit execution-failure signals can be recorded through
+the integrated scheduler's failure/success/quarantine methods; policy/claim failures are not
+automatically mislabeled as worker crashes.
+
+No new daemon, database or production write path is introduced.

+# Generic Compact Interface-Map Profiles
+
+The compact interface-map runtime is a reusable read-only control-plane capability. It keeps the

+Profile and classification are emitted by the compact-map module and revalidated by the worker
+before result submission. Unknown or mismatched profile/classification pairs fail closed.

+# Hermes / OpenClaw Online Agent Runtime
+
+## Goal
+
+Promote Hermes and OpenClaw from shadow-only adapter descriptions to real Online Agent workers
+without creating a second Task/claim protocol.
+
+Both workers reuse the existing P1/P2 Online Agent lifecycle:
+
+```text
+Online Task projected
+→ capability-filtered poll
+→ automatic claim
+→ heartbeat
+→ durable checkpoint
+→ external Agent execution
+→ attempt-aware result submission
+→ official verification
+```
+
+They do **not** change the existing TaskPlane `OpenClawAdapter/HermesAdapter` shadow contract. Those
+adapters remain side-effect-free compatibility surfaces.
+
+## Execution action
+
+The canonical execution envelope adds a read-only action:
+
+```text
+action=agent_runtime
+adapter=hermes | openclaw
+```
+
+The action requires capability `agent.runtime.<adapter>`, has an empty change set, no verification
+commands, and `writer_lease=false`.
+
+`project_online_task()` copies only bounded task fields into the signed execution envelope:
+
+- goal;
+- instructions;
+- success criteria;
+- non-secret constraints.
+
+The task may not choose a command, executable, URL, credential path, environment, or shell string.
+
+## Worker separation
+
+The generic engineering worker defaults to:
+
+```text
+AIOS_WORKER_ALLOWED_ADAPTERS=deterministic,source_capture,compact_interface_map,codex
+```
+
+so it skips Hermes/OpenClaw tasks before claim.
+
+Dedicated services advertise:
+
+```text
+Hermes:
+  AIOS_WORKER_CAPABILITIES=agent.runtime.hermes
+  AIOS_WORKER_ALLOWED_ADAPTERS=hermes
+
+OpenClaw:
+  AIOS_WORKER_CAPABILITIES=agent.runtime.openclaw
+  AIOS_WORKER_ALLOWED_ADAPTERS=openclaw
+```
+
+This makes adapter selection a pre-claim capability/fleet decision instead of a post-claim failure.
+
+## Credential-isolated executor
+
+The Online Agent worker itself still owns only Task API/Bridge coordination credentials. It writes
+a hash-bound request to `/var/lib/aios-external-agent-executor`.
+
+`aios-external-agent-executor.service` runs as the existing uncredentialed engineering executor user.
+It has:
+
+- one provider-only `LoadCredential` projection for the model-ready OneAPI environment;
+- `/etc/aios-gitops`, `/data/aios-gitops`, and the original provider-secret directory inaccessible;
+- no repository path;
+- no shell execution;
+- loopback denied, preventing direct access to the AIOS Task/Bridge control plane;
+- only the staging OneAPI container address allowed for the installed Agent runtime/provider;
+- only the exchange directory writable.
+
+The root-owned runtime profile in `/etc/aios/external-agent-runtime.d/<runtime>.json` decides the
+absolute executable, fixed non-secret environment, provider-only credential mapping, and I/O mode.
+A task cannot override any of these values. The profile may select `OPENAI_API_KEY` only from the
+systemd credential named `aios-external-agent-oneapi-env`; it cannot name a credential, inject an
+environment variable, or carry an inline secret. The runtime executor parses only the selected
+`ONEAPI_REGULAR_TOKEN` entry and does not expose the source file or other provider tiers to the
+child.
+
+## Runtime profile
+
+A profile supports:
+
+- `argv`: fixed argv, absolute allowlisted executable;
+- `input_mode`: `stdin_text`, `stdin_json`, or `file_json`;
+- `output_mode`: `stdout_text`, `stdout_json`, or `file_json`;
+- timeout;
+- bounded output size.
+
+`{input_json}` and `{output_json}` placeholders are allowed only for file modes. `{prompt}` is a
+root-profile-only argv placeholder populated from the bounded, signed task projection.
+
+The repository includes the staging profile templates validated against the installed Hermes
+v0.20.0 and OpenClaw v2026.7.2-beta.7 CLIs. Before activation, the Agent must re-run the actual
+`--help`/version probes and install the profiles and static configs root-owned. If the installed
+CLI differs, update only the root-owned profile/config projection and record the observed command;
+do not modify the Task contract to compensate.
+
+The provider projection is staging-only and uses the existing model-ready OneAPI source. It is not
+an AIOS Task, Bridge, GitOps, SSH, or Writer credential. Live activation remains blocked if the
+model-ready source cannot be projected through systemd or if the selected provider credential is
+missing/quota-invalid. This worker never passes API keys through task metadata or arbitrary
+environment variables.
+
+## Retry/restart
+
+The external request ID is deterministic over Task/Job/execution digest/runtime. The exchange keeps
+the request/result across worker restart. A repeated attempt with the exact execution digest reuses
+the durable external result instead of invoking the Agent twice.
+
+The normal P1 result idempotency/checkpoint path remains authoritative for Task result submission.
+
+## Result
+
+Successful execution returns:
+
+```text
+status=SUCCEEDED
+classification=EXTERNAL_AGENT_RUNTIME_SUCCEEDED
+execution_mode=agent_runtime
+agent_runtime=hermes | openclaw
+writer_lease=NONE
+changed_files=[]
+credential_material_exposed=false
+control_plane_access_granted_to_runtime=false
+```
+
+This first runtime version is intentionally read-only with respect to the repository. Engineering
+changes continue to use assistant-authored deterministic plans and governed WriterLease/commit.

+# Owner-Controlled Same-Binding Execution Rebind

+Governed Job, target branch, generation, or idempotency lineage.

+→ canonical Bridge resolves an already-registered deterministic plan

+```

+The service rejects arbitrary metadata patches. It derives the new envelope from canonical Bridge
+`/v2/execution-envelope`, validates every governed binding coordinate against the persisted envelope,
+requires `source_capture → deterministic`, requires exact old/new execution digests supplied by the
+Owner recovery request, and increments the Task revision under `BEGIN IMMEDIATE`.
+
+It records `TASK_EXECUTION_REBIND_AUTHORIZED` and an idempotent `task_execution_rebinds` receipt.
+No Task/Job/branch replacement is created and the worker still performs the real claim/heartbeat,
+WriterLease and governed commit.
+
+The endpoint is loopback-only:
+
+`POST /v1/tasks/{task_id}/execution-rebind`
+
+and requires the existing Owner control credential plus
+`AIOS_AGENT_TASK_EXECUTION_REBIND_AUTHORIZATION_ID`.
+
+Direct/manual Task database edits remain forbidden; the service is the audited mutation boundary.

Historical rows become `legacy`; their tenant is never guessed. Tenant tasks require `tenant_id`. System resources use `scope_type=system` without a fabricated tenant.

-# AIOS Action Connector Schema Final Closure — 2026-08-25
-
-## Disposition
-
-`NEEDS_REWORK`.
-
-The staging runtime and published OpenAPI contract are repaired and the public `/v2` staging route is now reachable. The final P0-C acceptance cannot be claimed because this execution environment has no callable ChatGPT Action/connector inspection or registration tool, and the deployed repository intentionally has no connector acknowledgement/write endpoint. Therefore the required proof of the actual callable tool schema, a real public two-file batch commit, and its public terminal reconcile are not available. The task must not be marked `SUCCEEDED`.
-
-No main, protected tag, baseline registry, or production write was performed.
-

-
-## Root causes and contract chain
-
-1. Runtime source was already repaired to require `files` for `commitFilesGoverned`. `active-runtime/app/aios_chatgpt_bridge_v2.py` declares the canonical required tuple and `render_openapi_contract_fragment()` emits the operation fragment.
-2. `scripts/build_v2r2c1_model_api_staging.py` copies the canonical `docs/gitops/openapi-chatgpt-actions.yaml` into the immutable staging artifact and rejects a build missing `/v2/commit-files`.
-3. The deployed public OpenAPI is served from the model API workspace at `/api/openapi-chatgpt-actions.yaml`; its SHA-256 was `a0775b0719a76e08a95f3257a3d3b2a73b70e1c55c162914250f80dd28da022d`. It contains `/v2/commit-files`, `files`, and item fields `path` and `content_base64`.
-4. The missing deployment link was Nginx: OpenAPI `servers.url` is `https://cnnetmkt.top` and its operation paths are `/v2/...`, but the live site had no `/v2/` location and the old `/api/v2/` location pointed at absent production port `18920`. The old `/api/file` route is an inactive legacy single-file router.
-5. A repository-wide and host-side inspection found no formal external ChatGPT connector registration source, schema cache, re-registration command, or acknowledgement endpoint. The existing durable-owner design explicitly states that no connector acknowledgement/write endpoint is provided and the only valid state is `PENDING_EXTERNAL_CONNECTOR`. This is the remaining external blocker, not a reason to create a parallel local schema or reuse another credential.
-
-## Changes made
-
-- `ops/gitops-migration/bind_external_action_surface_final_staging.sh`
-  - added an idempotent exact `/v2/` route to staging Bridge `127.0.0.1:18892`;
-  - forwards `Authorization` and `X-AIOS-Token`;
-  - keeps the existing exact governed-read routes on `18890` and generic `/api/` on `18893`;
-  - refuses an incomplete existing staging route and never adds a route to production `18920`.
-- `tests/test_action_contract_regressions.py`
-  - added a parity/deployment test tying published `/v2/commit-files` to the staging route and asserting no `18920` target in the staging installer.
-- `runbooks/action-connector-schema-refresh-20260825.md`
-  - added the durable connector refresh and fail-closed acceptance procedure.
-- `reports/action-connector-schema-final-closure-20260825.md`
-  - this evidence report.
-
-The source/runtime contract parity test remains in place and still compares runtime required fields, generated fragment, and published schema. The live connector layer cannot be parity-tested because no connector layer is deployed or callable from this environment; the gate therefore remains fail-closed rather than accepting a fixture as proof.
-
-## Deployment and restart evidence
-
-The existing staging installer was run after `git diff --check` and focused tests. It created the Nginx backup `/data/aios-gitops/backups/action-surface-final-20260825T105656Z`, passed `nginx -t`, and reloaded Nginx. Public readback then returned HTTP 200 for:
-
-- `https://cnnetmkt.top/v2/runtime`
-- `https://cnnetmkt.top/v2/capabilities`
-- `https://cnnetmkt.top/api/openapi-chatgpt-actions.yaml`
-
-The staging Bridge and Model API were subsequently restarted once. Both `systemctl is-active` checks returned `active`. Post-restart `/v2/runtime` retained the staging identity and artifact SHA above; `/v2/capabilities` retained `commitFilesGoverned.required_fields` including `files`.
-
-## Tests and live smoke
-
-Passing results:
-
-- `python3 -m pytest -q tests/test_action_contract_regressions.py tests/test_bridge_v2_governed_http_bootstrap.py` — `17 passed`.
-- Mandatory suite — `264 passed, 28 subtests passed in 4.81s`.
-- Full repository suite — `720 passed, 2 skipped, 2 failed, 154 subtests passed in 34.02s`. The two failures are unchanged known failures: stale `/tmp/aios-agent-events-test` fixture and deployed signer self-test return code `42`.
-
-Post-restart live results:
-
-- `getReleaseConsistency(V2R2C1, ...)`: HTTP 200 structured consistency response; no Gitea URL validation failure. Gitea listing and peeled target readback were visible.
-- `runReleaseAcceptance(V2R2C1, ...)`: HTTP 200 structured policy result with `accepted=false`; it reached policy evaluation rather than failing URL validation.
-- `getTagPublicationStatus("V2R2C1")`: HTTP 200 structured state (`REMOTE_PUSH_PENDING` on Bridge v2; the legacy model read surface returned structured `UNKNOWN`).
-- `getReleaseSaga(nonexistent)`: HTTP 404, normal NOT_FOUND behavior.
-- Existing terminal job `job-93138017f3afd7f709f691fd05c77923`: HTTP 200, `COMPLETED`, revision `8`; terminal `/v2/job/reconcile` returned HTTP 200 with the same `COMPLETED` receipt and Authority/API/Git remote OID `904e7ea0cd376d204bad19628c36a9dd90ca6621`.
-- Empty diff: HTTP 200, zero paths/size, `truncated=false`.
-- Non-empty diff: HTTP 200 with identities, changed paths, stats, total size, patch limit `262144`, and bounded response fields.
-- Public `POST /v2/commit-files` probes returned `BRIDGE_REQUEST_FIELDS_MISSING` for incomplete bodies; the body containing `files` was not rejected as an unknown field. No write side effect occurred.
-
-## Missing final acceptance
-
-The following required evidence is not available and is intentionally not inferred:
-
-- actual ChatGPT callable Action tool schema showing required `files`;
-- formal connector re-register/cache invalidation acknowledgement;
-- an authorized public `commitFilesGoverned` request containing two files;
-- Authority/Gitea/API remote OID equality for that new batch commit;
-- its batch Job `COMPLETED` readback and public terminal reconcile;
-- post-batch connector callable smoke.
-
-The prior single-file public commit `904e7ea0cd376d204bad19628c36a9dd90ca6621` and its terminal reconcile are preserved as baseline evidence only; they are not substituted for the required batch proof.
-
-## Protected boundaries and rollback
-
-No source or deployment operation wrote `main`, a protected tag, the baseline registry, or production. The production-facing `18920` route was not changed; the new `/v2/` location targets only the staging Bridge listener. No secret value was printed, rotated, or reused. Automatic rollback was not triggered because Nginx syntax, staging service health, runtime identity, Gitea readback, and protected-ref boundaries remained valid. If a future connector refresh breaks these checks, restore the Nginx backup and the preceding staging artifact through the existing governed installer, then re-run the same probes.
-
-## Next required owner/platform action
-
-Provide the supported staging external Action connector lifecycle (registration/re-registration/cache invalidation) and an authorized staging Action bearer, or have the legitimate external Agent claim the existing continuation task and produce its durable callable-schema and batch-commit evidence. Until then the correct disposition remains `NEEDS_REWORK`; do not mark `SUCCEEDED` based on the server-side OpenAPI alone.

-# Action Contract Regression Remediation — 2026-08-25
-
-## Scope
-
-Governed task: `fix-action-contracts-20260825-1407`
-Base: `3244f0f17f8845592ac94d585f5ebd65693c9f29`
-Target branch: `agent/fix-action-contracts-20260825-1407`
-
-## Verified regressions
-
-1. `getReleaseConsistency` and `runReleaseAcceptance` fail before evaluation with:
-   `Gitea API URL must be HTTP(S)`.
-   V2R2C1 release evidence at `a8b906d1bc24088c19647e98de6a679268f6d0a2`
-   proves Gitea API readback passed for target `998d30304787e31e5ae607c0bd86b5edb2b0e5ad`.
-   Therefore current staging/contract overlay configuration has regressed.
-
-2. `getReleaseSaga` fails with:
-   `Permission denied: '/var/lib/aios-gitops/silent-release'`.
-   Runtime service identity must have read/traverse access to the durable release state root.
-   Fix ownership/group/ACL at deployment time; do not broaden to world-writable permissions.
-
-3. `getTagPublicationStatus` rejects the authoritative approved version `V2R2C1`
-   as `invalid release version`, while `getGovernedWriteCapabilities` returns the same
-   version as the approved release scope. The two Action contracts are internally inconsistent.
-   Release-version validation must accept the canonical AIOS `^V[0-9]+R[0-9]+C[0-9]+$`
-   namespace (or, preferably, use one shared validator for all release Actions).
-
-4. `commitFilesGoverned` is unusable from the published Action schema.
-   Runtime capability metadata declares required fields:
-   `task_id, repository, expected_branch_oid, target_branch, generation, idempotency_key, files, message`,
-   but the exposed tool contract has no `files` input. Regenerate/publish the Action schema from
-   the same operation contract source and add a contract-parity test.
-
-5. `reconcileGitOpsJob` returned `DURABLE_BINDING_INVALID` for a completed governed
-   single-file job that was otherwise read back as `COMPLETED`.
-   Reconciliation of a valid terminal job should be idempotent/read-only and must not require
-   a stale or absent active lease. Add a regression case for terminal completed jobs.
-
-6. `getDiff` returns `ResponseTooLargeError` / `GIT_OUTPUT_LIMIT_EXCEEDED` for large diffs.
-   Add server-side bounded output: path/stat summary plus truncation metadata, or pagination.
-   The Action must never fail merely because a valid repository diff is large.
-
-## Required implementation changes
-
-- Centralize release-version parsing and reuse it in tag status, candidate, consistency, and acceptance.
-- Validate/normalize Gitea API URL at service startup and fail health checks with a configuration-specific diagnostic.
-- Ensure the deployment unit projects a valid HTTP(S) Gitea API base URL into the staging overlay.
-- Correct durable release-state directory ownership/ACL for the runtime service account.
-- Generate the external Action schema from the runtime operation contract; parity-test required fields.
-- Make terminal reconciliation idempotent and independent of expired active writer leases.
-- Bound diff output and return `truncated=true` with deterministic metadata rather than transport failure.
-
-## Acceptance gates
-
-All must pass on the same deployed overlay:
-
-- `getReleaseConsistency(V2R2C1, 998d303..., a8b906d..., approved_plan)` returns a structured result, not URL error.
-- `runReleaseAcceptance(...)` reaches policy evaluation, not URL error.
-- `getTagPublicationStatus("V2R2C1")` returns structured publication state.
-- `getReleaseSaga(nonexistent_candidate)` returns NOT_FOUND/empty-state semantics, never filesystem permission failure.
-- Published `commitFilesGoverned` schema exposes `files` and a two-file isolated branch commit succeeds.
-- Reconcile of a completed governed job is idempotent.
-- Large diff returns bounded/truncated data rather than transport exception.
-- Existing protected-ref controls remain unchanged: no direct main/tag/baseline/production write.
-
-## Proven stable reference
-
-V2R2C1 evidence closure (`a8b906d1bc24088c19647e98de6a679268f6d0a2`) records:
-- Gitea Git/API readback PASS
-- staging runtime PASS
-- restart recovery PASS
-- 59 mandatory tests passed / 0 failed
-
-This evidence should be used as the compatibility baseline when repairing the current
-`contract-overlay-v2` / `scheme-a-323b615b...` staging layer.

-# AIOS Action contract repair evidence — 2026-08-25
-
-## Disposition
-
-Final disposition: `NEEDS_REWORK`.
-
-The contract repair is deployed to staging and the focused acceptance checks are green. The task is not eligible for `SUCCEEDED`: `runReleaseAcceptance` returns structured policy output with `accepted=false` because the existing publication state for protected tag `V2R2C1` is `REMOTE_PUSH_PENDING`, and the repository-wide suite still has the two pre-existing signer/event-bus failures recorded below. The online Task API row is still `QUEUED`; it was not changed by direct database manipulation or an unauthorized synthetic claim/result.
-
-No production release, `main`, release tag, baseline registry, or production service was directly modified.
-
-## Scope and pre-change facts
-
-- Repository: `aios/aios`; governed branch: `agent/fix-action-contracts-20260825-1407`.
-- Initial task branch HEAD: `35eec9afe1432e8466d60040b2fb1049bb41242a`.
-- Stable reference: `V2R2C1`; source commit `998d30304787e31e5ae607c0bd86b5edb2b0e5ad`; evidence closure `a8b906d1bc24088c19647e98de6a679268f6d0a2`.
-- Pre-change refs: authority `main=3244f0f17f8845592ac94d585f5ebd65693c9f29`, tag `V2R2C1=07fc2746b688f5f243f29b39de39f32edc3dd9d2`; these remained unchanged.
-- Staging services run as `User=aiman`, `Group=gitops`. The actual staging Gitea API base is `https://g.cnnetmkt.top/git/api/v1`, supplied by systemd environment rather than business-code host constants.
-- Pre-change full test baseline: `707 passed, 2 skipped, 154 subtests passed, 2 failed`. The failures were the stale `/tmp/aios-agent-events-test` event-bus fixture and the real signer self-test.
-
-## Root causes and repairs
-
-1. Gitea URL validation occurred at release-operation time while the staging overlay's API environment was not consistently projected into all runtime paths. The canonical HTTP(S) validator is now called during model and Bridge startup; `getReleaseConsistency` and `runReleaseAcceptance` use the actual staging environment URL.
-
-2. `silent-release` was not consistently writable by the real service identity, and the credential helper parent directory blocked `aiman` traversal. The persisted staging systemd overlay creates the state directory as `aiman:gitops` mode `0750` and grants only `u:aiman:--x` on `/usr/local/libexec`; no world-writable mode was used. The staging bridge also has the minimum repository write path required by the governed AuthorityGitExecutor/CAS flow.
-
-3. Release version parsing was split across callers and rejected `V2R2C1`. A shared canonical parser now accepts `^V[0-9]+R[0-9]+C[0-9]+$` plus the existing bounded suffix form, and is used by capabilities, release candidate, consistency, acceptance, tag publication, and release/tag queries.
-
-4. The runtime operation contract required `files` but the published Action schema omitted it. `commitFilesGoverned` now has one contract source and published schema projection, with parity tests. A real governed two-file commit completed on isolated branch `agent/action-contract-integration-20260825-1407`; authority, Git remote, and Gitea API all read back OID `0345cd8c70967940bc8e9132dff7d6ea11efa304`.
-
-5. `reconcileGitOpsJob` reconstructed active lease state before checking terminal state. Terminal `COMPLETED`, `FAILED`, and `CANCELLED` jobs now short-circuit to idempotent read-back; active jobs retain strict lease validation. The two-file job reconciled as `COMPLETED` and a second reconcile returned the same receipt.
-
-6. `getDiff` returned unbounded patch data and could fail the transport. It now returns identities, changed paths, stats, total bytes, bounded patch output, patch limit, and `truncated`. The large smoke returned `total_size_bytes=350222`, `stdout_bytes=262144`, `patch_limit_bytes=262144`, `truncated=true`; no `ResponseTooLargeError` or `GIT_OUTPUT_LIMIT_EXCEEDED` escaped.
-
-During live integration, two additional staging-only contract defects were found and repaired: CREATE_NEW branch normalization/CAS recovery, and release executor projection of the configured staging baseline plus immutable runtime `versions/V2R2C1.json`. The latter removed the missing publication-workspace baseline/version errors without writing production state.
-
-## Source, test, and operational changes
-
-Source commits on the governed branch include the six contract repairs, focused regression tests, `versions/V2R2C1.json`, governed CREATE_NEW/reconcile recovery, and final runtime projection commits. The final source before this evidence commit is `2ec49005bde44f6981b14351500847d594e0276c`.
-
-The runbook update is in `runbooks/agent-fix-action-contracts-20260825.md`. This report is the required durable evidence artifact. Existing untracked `runtime/agent-observability/` and `runtime/task-center/` directories were preserved and were not staged.
-
-Tests run on the final source:
-
-```text
-PYTHONPATH=active-runtime/app python3 -m pytest -q tests/test_silent_release_execution_readiness.py tests/test_silent_release_controller.py tests/test_silent_release_hardening.py tests/test_silent_release_production_contract.py tests/test_chatgpt_actions_tag.py tests/test_gitea_tag_publication.py tests/test_authoritative_git_context.py

-
-The full-suite failures remain the known event-bus fixture failure and the real signer adapter self-test (`returncode=42`); no new mandatory-suite regression was observed. Focused contract/reconcile tests and the exact mandatory suite passed.

-- Artifact SHA256: `f67aed6cc0cce1f08197485c3eea204d3ef4d3989f44dc98e8ea2691e5886cbf`.
-- Deployment state: `STAGING`; production-deployed flag: `false`.
-- A lexically highest staging-only systemd drop-in was installed for each affected service, followed by `daemon-reload` and restart. `systemctl is-active` returned `active` for both services, and `systemctl show` confirmed the final OID, artifact SHA, API URL, and baseline authority.
-
-## Runtime smoke evidence
-
-- Model health returned `status=ok`, `version=V2R2C1`, final commit/artifact identity, `deployment_state=STAGING`, and `production_deployed=false`.
-- Bridge/API readback was available; the bridge's `/health` path is not exposed by this runtime and returned `404`, while its governed endpoints were healthy.
-- `getReleaseConsistency("V2R2C1", ...)` returned structured `status=PASS`, with Gitea listing/peeled target and tag object matching the stable reference.
-- `runReleaseAcceptance(...)` entered policy evaluation and returned structured `accepted=false`; it did not fail URL validation. The independent pre-existing tag publication state is `REMOTE_PUSH_PENDING`, with the remote rejection explicitly reporting protected tag `V2R2C1`.
-- `getTagPublicationStatus("V2R2C1")` returned structured `REMOTE_PUSH_PENDING`, not `invalid release version`.
-- `getReleaseSaga` for a nonexistent candidate returned HTTP `404` with `status=NOT_FOUND`, `state=NOT_FOUND`, `execution_enabled=false`, and no filesystem permission error.
-- `commitFilesGoverned` published schema includes required `files`, with per-file `path` and `content_base64`.
-- Two-file governed commit: branch `agent/action-contract-integration-20260825-1407`, OID `0345cd8c70967940bc8e9132dff7d6ea11efa304` at authority/Git remote/API; protected-ref flags remained false.
-- Terminal reconcile: `COMPLETED` read-back was idempotent across two calls; focused tests cover `FAILED` and `CANCELLED` terminal semantics.
-- Small diff returned bounded non-truncated output; empty diff returned zero paths and zero bytes; large diff returned bounded/truncated output as recorded above.
-- Main, protected tag, baseline registry, and production OIDs were re-read after deployment and remained unchanged.
-
-## Restart persistence and remaining risk
-
-The final staging services were restarted after deployment and health/runtime identity were re-read. The post-restart `systemctl is-active` result was `active` for both services; model health again reported OID `2ec49005bde44f6981b14351500847d594e0276c`, artifact SHA `f67aed6cc0cce1f08197485c3eea204d3ef4d3989f44dc98e8ea2691e5886cbf`, staging mode, and `production_deployed=false`. Post-restart consistency remained `PASS`, acceptance remained structured `accepted=false` for the pre-existing protected-tag publication state, saga remained `NOT_FOUND` for the nonexistent candidate, and the large diff remained bounded/truncated. The task cannot be promoted to `SUCCEEDED` until the protected-tag publication state and the two known repository-wide failures are resolved through their respective governed owners. No automatic rollback was performed because the staging services stayed healthy, mandatory tests passed, Gitea readback passed, and protected-ref boundaries remained intact.
-
-Task disposition is `NEEDS_REWORK`, not `SUCCEEDED`: the staging contract repair is materially complete, but the deployed acceptance result is not all-green and the task row has not been legitimately claimed/verified by the online task worker.
-
-## External Action Surface final closure evidence — 2026-08-25
-
-### Disposition
-NEEDS_REWORK. Staging is deployed and P0-A/P0-B have live closure evidence. P0-C is blocked: no formal staging external Action bearer issuance path was available, so the required real public two-file commit and terminal reconcile were not authorized or executed. Do not mark SUCCEEDED. No main, tag, baseline, or production write occurred; untracked runtime/agent-observability and runtime/task-center were preserved.
-
-### Identity and before-change facts
-Authority /data/aios-gitops/repo.git; worktree /var/lib/aios-gitops/bridge-v2-staging/worktrees/fix-action-contracts-20260825-1407; branch agent/fix-action-contracts-20260825-1407; initial HEAD 35eec9afe1432e8466d60040b2fb1049bb41242a1. Stable V2R2C1 source 998d30304787e31e5ae607c0bd86b5edb2b0e5ad; evidence closure a8b906d1bc24088c19647e98de6a679268f6d0a2. Repair commit 174e64dd0218cef6d49dd13d58bbd90c78fecadd; protected refs unchanged.
-
-### P0-A governed-read ownership
-Root cause: generic /api/ sent governed-write-capabilities to model API 18893 (404), while governed facade 18890 owned it. Fix: ops/gitops-migration/bind_external_action_surface_final_staging.sh installs exact locations for governed-write-capabilities, control-plane-snapshot, online-agent-task, and online-agent-task-events to 18890; generic /api/ remains 18893; auth headers forward and no business host is hard-coded. Backup /data/aios-gitops/backups/action-surface-final-20260825T101714Z; log /data/aios-gitops/logs/action-surface-final-20260825T101714Z.log. nginx -t passed, Nginx active, public GET /api/governed-write-capabilities HTTP 200. Contract reports governed writes enabled but legacy/main/tag/baseline/production writes false.
-
-### P0-B release semantics
-Root cause: public model GET used local TagPublisher/PublicationStore lacking tag object binding, so consistency was FAIL/tag_object=false; Bridge v2 had authoritative durable binding. Fix: active-runtime/app/aios_model_api_staging.py constructs one canonical publication request and routes release-consistency/release-acceptance through Bridge v2 getReleaseConsistency/runReleaseAcceptance; tests/test_action_contract_regressions.py covers this. Live V2R2C1 consistency with target 998d30304787e31e5ae607c0bd86b5edb2b0e5ad, closure a8b906d1bc24088c19647e98de6a679268f6d0a2, plan sha256:c0df52008ae7f64cec5ee2d28947aa7b892066c670ab8295e4549140b1a7500e returned HTTP 200 PASS, all checks true, tag object 07fc2746b688f5f243f29b39de39f32edc3dd9d2 and peeled target correct. Acceptance entered structured policy evaluation with accepted=false, not URL failure. Tag publication V2R2C1 returned structured UNKNOWN, not invalid version.
-
-### P0-C credential and commit blocker
-Hash-only Action record: account chatgpt-gitops-bot; id chatgpt-action-0a3e55b7659a4d4e8125feabce5e8bf5; kind gpt_action_api_key; consumer aios-gitops-model-api.service; issuer owner_ssh_breakglass_rotation; issued 2026-08-10T04:51:58.900488Z; expires 2026-09-09T04:51:58.900488Z; scopes file:write and agent-task:control; disabled false; owner approval required true. Plaintext was not printed/reused. agent_task_control_token is not an Action bearer. Inspected Writer grants, Gitea consumer, SSH, task broker and old token candidates provide no formal issuer; no unrelated credential substituted. Empty public POST /api/commitFilesGoverned reached staging and returned HTTP 423 gitops_writes_disabled with AIOS_GITOPS_WRITES_ENABLED=false. Writes were not enabled. No real public two-file commit or COMPLETED reconcile is claimed. Blocker: FORMAL_STAGING_ACTION_BEARER_ISSUANCE_NOT_AVAILABLE.

Same known failures: stale /tmp/aios-agent-events-test in test_unified_event_flow; signer adapter self-test return 42 in test_real_signer_help_and_self_test_are_available.
-
-### Restart and smoke
-After first deployment, model and Bridge staging services were restarted and remained active. Post-restart health retained source/artifact identity, V2R2C1, STAGING, production false. Capability HTTP 200; consistency HTTP 200/PASS; tag status structured UNKNOWN; nonexistent saga HTTP 404/NOT_FOUND with execution false, shadow true, side effects false. Empty diff HTTP 200, zero paths/size, truncated false. Bounded non-empty diff returned identities, paths/stats, bounded output and patch limit 262144; local pipe-to-head caused only expected curl broken-pipe. Existing large-diff behavior remains bounded/truncated with no transport exception. Gitea readback proven by consistency PASS; protected-ref boundary remained fail-closed.
-
-### Task continuity and remaining work
-Earlier execution observed TASK_NOT_FOUND and created continuation fix-action-contracts-20260825-1407-external-surface-closure with parent/source/OID and staging constraints. Later recheck returned parent HTTP 200 QUEUED; continuation also QUEUED, revision 1, claimed_by null, result null. Neither has claim, execution, terminal result, or success evidence. Required rework is formal bearer lifecycle, isolated real two-file public commit and OID/reconcile verification, disposition of the two pre-existing full-suite failures, then full smoke before SUCCEEDED.
-### Health endpoint clarification
-
-The service health contract is /api/health: local model port 18893 and public https://cnnetmkt.top/api/health both returned HTTP 200 with the deployed source/artifact identity, STAGING, and production_deployed=false. Public root /health returned HTTP 502 because the existing Nginx root location proxies the separate portal upstream on 127.0.0.1:3000; it is not the Action model health route. This unrelated portal-ingress 502 is recorded as an observed remaining staging risk, and was not changed because this task scope is the Action/Bridge/release surface.
-
-\n
-### Formal task-state boundary
-
-The deployed Task API exposes verification decisions SUCCEEDED, NEEDS_REWORK, and FAILED only through POST /v1/tasks/{id}/verify while the task is VERIFYING. Both the parent and continuation were QUEUED with no claim, so a direct NEEDS_REWORK transition was not a legal API operation. No cancel, database edit, fake claim, or lifecycle bypass was performed. This report is the authoritative disposition for this run: NEEDS_REWORK.

-
-## 根因与修复
-
-1. Autonomous Agent 没有安全 read seam：增加 `AuthorityGitExecutor.read_file` 和 `readRepositoryFile`，只读 authoritative bare Git object database，固定响应上限并返回 resolved commit/OID、size、SHA-256、base64。
-2. Lease 没有跨重启 durable binding：增加 `ScopedLeaseStore` SQLite CAS 状态，绑定 task/repository/branch/expected OID/generation/TTL，支持同 binding 幂等、冲突、过期和 USED replay；commit 先校验 lease，再走既有 detached worktree/Job Controller/Authority CAS chain。
-3. Lease 曾可由调用者声明治理身份：现在必须命中 durable task binding，公开路径只接受 `CONTINUE_EXISTING`，并要求 expected OID 等于当前 authority branch head。
-4. Auth scope 曾混合：Bridge 按 read/lease/commit operation 分别检查 scope；model-api facade 认证后透传 bearer。
-5. runtime contract 与 published schema：增加 read/lease operation，保留 `commitFilesGoverned.files[] = {path, content_base64}`，builder 将 `scoped_lease_store.py` 纳入 immutable artifact。

-- 未宣称完整 Action smoke、restart 后 governed commit 或 `TASK_VERIFIED`。
-
-## 保护边界
-
-本轮只安装 staging artifact/drop-in；production service 未重启。`main`、`V2R2C1` tag、baseline target/evidence closure 未写入。两个既有 untracked 目录 `runtime/agent-observability/`、`runtime/task-center/` 原样保留。
-
-## 剩余风险与下一步
-
-主要闭环阻塞是：需要 Owner/正式 Action broker 提供当前有效 bearer（不在聊天中传递）。此外 mandatory suite 仍有上述两个已知环境/部署失败。拿到 bearer 后应从当前 branch HEAD 重新读取 source OID，按 runbook 执行一次真实两文件 governed commit、Gitea 三方 OID readback、idempotency/stale-OID 负例、staging restart 后复测；在此之前 Task 必须保持 `BLOCKED/NEEDS_REWORK`，不能标记 `SUCCEEDED`。

-## 根因与决策
-
-根因不是 URL host 或 YAML 传输错误，而是公开 Action projection 中混入了旧式
-Git 写原语和同义 approval alias。公开 schema 同时暴露 legacy primitives 与
-`commitFilesGoverned`，最终 operation 数为 32。
-
-本次投影收缩为 26 个 operation：
-
-- 先前修复中移除粗粒度旧别名 `POST /api/file` (`commitFile`)；
-- 先前修复中移除当前 isolated-writer policy 明确禁止的 `POST /api/commit`
-  (`commitChanges`)；
-- 本轮移除 `submitSignedApproval`，因为它是 `submitOwnerApproval` 的 alias；
-- 本轮从 Actions projection 隐藏 `createPatch`、`createBranch`、
-  `commitFileAtomic` 三个旧式 Git 写原语。runtime 兼容处理没有删除，canonical
-  对外批量写入为 `/v2/commit-files`；
-- 保留 release candidate、release consistency、release acceptance、tag
-  publication status、release saga、getDiff 和 recovery 相关既有能力，满足本任务
-  的既有 smoke contract。尚未实现的 `getReleaseSnapshot`/`getReleaseVerification`
-  聚合 API 不在本次冒险重构范围内。
-
-此外，`commitFilesGoverned` 的 runtime fragment 生成器现在生成：
-
-- `security: [{bearerAuth: []}]`；
-- `x-openai-isConsequential: true`；

-# Runbook Addendum — External Action Connector Schema Refresh
-
-This addendum is staging-only and applies to the `fix-action-contracts-20260825-1407` closure.
-
-## Contract source
-
-Use `active-runtime/app/aios_chatgpt_bridge_v2.py` as the runtime source of required fields. Use `render_openapi_contract_fragment()` and `docs/gitops/openapi-chatgpt-actions.yaml` for the generated/published projection. `commitFilesGoverned` must require `files`, and each item must require `path` and `content_base64`.
-
-The public OpenAPI server is the site root and its Bridge v2 paths are `/v2/...`. Install the route with `ops/gitops-migration/bind_external_action_surface_final_staging.sh`; it must target `127.0.0.1:18892`, preserve the Authorization headers, pass `nginx -t`, reload Nginx, and never target production `18920`.
-
-## Connector lifecycle gate
-
-The external Action connector must be refreshed through its supported registration or re-registration lifecycle. Record the connector identity, schema source URL, fetched schema digest, cache invalidation or registration acknowledgement, and a callable-tool inspection showing required `files`. Do not make a local fixture or a second hand-written schema a substitute for this evidence.
-
-If the connector registration API, cache lifecycle, callable inspection, or formal staging Action bearer is unavailable, stop at `PENDING_EXTERNAL_CONNECTOR` and record `FORMAL_STAGING_ACTION_BEARER_ISSUANCE_NOT_AVAILABLE`. Never reuse Gitea, SSH, task-control, Writer, or old token credentials.
-
-## Acceptance
-
-After connector refresh, use the actual callable Action once to submit two files through `commitFilesGoverned` on an isolated `agent/*` branch. Verify the task/lease lineage, Authority ref, Git remote ref, and Gitea API branch OID are equal. Read the durable job, require `COMPLETED`, then call terminal reconcile and require an idempotent successful read-back. Restart only staging Action/Bridge/model services and repeat callable schema inspection and the batch/reconcile smoke.
-
-Do not mark `SUCCEEDED` until the callable schema and batch evidence exist. If refresh breaks health, routes, auth, schema, or protected-ref boundaries, restore the recorded Nginx backup and previous staging artifact through the governed deployment procedure, then diagnose.

-# ChatGPT Action OpenAPI 操作数上限运行手册
-
-## 目的
-
-`https://cnnetmkt.top/api/openapi-chatgpt-actions.yaml` 必须保持不超过 ChatGPT
-Action 导入支持的 30 个实际操作；当前投影硬门槛收紧为 26，为未来治理、诊断
-和任务协议保留余量。OpenAPI 中同一路径的多个 HTTP method 分别计数；路径数量
-不等于操作数量。
-
-## 单一来源与构建
-
-规范唯一来源是 `docs/gitops/openapi-chatgpt-actions.yaml`。模型 API staging
-构建脚本 `scripts/build_v2r2c1_model_api_staging.py` 将该文件复制到 immutable
-artifact，并同时校验 `/v2/commit-files` runtime contract。禁止直接编辑已部署
-artifact 或 production 文件。
-

-from pathlib import Path
-doc = yaml.safe_load(Path('docs/gitops/openapi-chatgpt-actions.yaml').read_text())

-PYTHONPATH=active-runtime/app python3 -m pytest -q tests/test_action_contract_regressions.py

-
-## 公开面选择
-
-公开 schema 保留受治理的 `/v2/commit-files` 以及 release、
-tag publication、consistency、acceptance、saga 和 diff 操作。粗粒度旧别名
-`/api/file`、`/api/commit`、`/api/branch`、`/api/patch` POST、`/api/commit-file`
-以及 `/submitSignedApproval` 等旧别名/旧写原语不得重新加入公开 Action schema；
-批量写入使用 `/v2/commit-files`。完整 runtime 兼容路由不因此删除。
-
-`commitFilesGoverned` 必须显式声明 `security: [{bearerAuth: []}]` 和
-`x-openai-isConsequential: true`；schema 与 Bridge runtime 的 required fields、
-batch limits 必须由同一生成链维护。
-
-## 部署与复验
-
-只使用 `scripts/build_v2r2c1_model_api_staging.py` 生成 staging artifact，保留
-当前 systemd drop-in 备份，更新 staging model-api 的 artifact 路径后执行
-`daemon-reload` 和 staging unit restart。部署后从公网重新抓取 schema，验证：
-
-- HTTP 200，Content-Type 为 YAML；
-- 实际操作数为 30 或更少；
-- `commitFilesGoverned` 仍包含 required `files`，每项包含 `path`、`content_base64`；
-- `/v2/runtime`、capabilities、release consistency/acceptance、tag status、
-  saga empty-state、diff small/empty/large smoke 均正常；
-- staging unit active，production/main/tag/baseline 未写入。
-
-Action 客户端可能缓存旧规范。公网 schema 复验通过后，在 ChatGPT Action 编辑器

-# Agent Execution Contract — Action Contract Regression Repair
-
-## Objective
-
-Fully repair the current AIOS Action runtime/contract overlay regressions on the single server, without modifying protected refs directly and without introducing new infrastructure. The task is not complete until the deployed staging/action overlay passes all acceptance gates.
-
-## Authority and scope
-
-- Repository: `aios/aios`
-- Base at task creation: `3244f0f17f8845592ac94d585f5ebd65693c9f29`
-- Governed task: `fix-action-contracts-20260825-1407`
-- Target branch: `agent/fix-action-contracts-20260825-1407`
-- Protected refs must not be directly written: `main`, release tags, baseline registry, production runtime.
-- No new SaaS, database, agent framework, or monitoring platform may be introduced.
-
-## Non-interactive rules
-
-The Agent must run the whole flow unnattended:
-
-1. Collect facts.
-2. Determine root causes.
-3. Make the smallest correct changes.
-4. Run unit/integration/contract tests.
-5. Deploy to staging only.
-6. Restart only the affected non-production services.
-7. Run the full Action smoke suite.
-8. On failure, automatically collect logs, diagnose, fix, and retry.
-9. If a change causes a new regression, automatically roll back the staging change to the previous known-good configuration and record the failure.
-10. Stop only if an owner decision is required for a high-risk, irreversible, or production-boundary action.
-
-## Fact collection — required before editing
-
-Record all of the following in the final evidence bundle:
-
-- `id`, `hostname`, `uname -a`, `date --iso-seconds`
-- `git rev-parse --show HEAD` for authority worktree and running overlay source
-- `git status --porcelaine=v2`
-- `git remote -v`
-- current systemd service unit(s), drop-ins, Environment/EnvironmentFile sources for GitOps/Bredge/release services
-- `systemctl show <affected-service>` including `User=`, `Group=`, `Environment=`, `EnvironmentFile=`, `ExecStart=`
-- resolved Gitea API base URL after env/config expansion; redact secrets but not scheme/host
-- `stat -c, `namei -l`, `getfacl`, als -ld on `/var/lib/aios-gitops/silent-release` and its parents
-- find Action OpenAPI/schema generator and runtime operation definitions for `commitFilesGoverned`
-- find the release version validator(s) and all callers of `getTagPublicationStatus`
-- find `reconcileGitOpsJob` implementation and durable binding validation logic
-- find `getDiff  implementation and transport output limits
-
-Do not edit any file until the actual implementation and configuration sources have been located.
-
-## Repair 1 — Gitea API URL
-
-Symptoms:
-
-- `getReleaseConsistency` → `Gitea API URL must be HTTP(S)`
-- `runReleaseAcceptance` → `Gitea API URL must be HTTP(ÊX
-
-Required behavior:
-
-- Determine which env/config key is projected into the current contract overlay.
-- Compare the deployed overlay with V2R2C1 known-good configuration/deployment manifests.
-- Restore a valid `HTTP://` or `HTTPS://` Gitea API base URL.
-- Add startup config validation so invalid schemes fail at health/startup with a config-specific message, not during a release check.
-- Never hard-code a different Gitea host if the existing deployment already has a single authoritative source.
-
-## Repair 2 — durable release state permissions
-
-Symptom:
-
-- `getReleaseSaga` → `Permission denied: '/var/lib/aios-gitops/silent-release'`
-
-Required behavior:
-
-- Identify the actual runtime service User/Group.
-- Grant only the required traverse/read/write permissions for the durable state directories the service must use.
-- Prefer ownership + group mode or a specific ACL; keep the directory non-world-writable.
-- Persist the permission in deployment/install logic so restart/reboot does not regress.
-- Verify create/read/update of a staging-only saga state file under the service identity.
-
-## Repair 3 — release version contract
-
-Symptom:
-
-- `getTagPublicationStatus("V2R2C1")` → `invalid release version`
-- The same runtime exposes `V2R2C1` as `approved_release_version`.
-
-Required behavior:
-
-- Locate all version validators; consolidate onto one canonical parser.
-- Accept the AIOS canonical namespace `^V[0-9]+R[0-9]+C[0-9]+$`.
-- Preserve any additional already-supported legacy formats unless they are security-sensitive.
- - Add contract tests proving that the version accepted by capabilities is accepted by status, candidate, consistency, acceptance, and tag publication.
-
-## Repair 4 — `commitFilesGoverned` schema parity
-
-Symptom:
-
-- Runtime capability metadata requires `files`.
-- Published Action tool schema does not expose `files`.
-- Call reaches Bridge and fails `BRIDGE_REQUEST_FIELDS_MISSING`.
-
-Required behavior:
-
-- Find the canonical runtime operation contract.
-- Generate the external tool schema from the same source of truth; do not manually copy a parallel schema.
-- `files` must be required and must represent a list of file objects with at least `path` and `content_base64`.
-- Add a parity test that compares runtime required fields with published Action required fields.
-- Add a real governed commit test that writes two test files to an isolated `agent/` ibranch and verifies remote OID.
-
-## Repair 5 — terminal reconciliation
-
-Symptom:
-
-- A governed job read back as `COMPLETED' but `reconcileGitOpsJob` failed `DURABLE_BINDING_INVALID`.
-
-Required behavior:
-
-- Reconciling a terminal successful job must be idempotent.
-- An expired writer lease must not invalidate a durable binding for a job that is already terminal.
-- Active-job reconciliation may require a live lease; terminal read-back must not.
-- Add cases for COMPLETED, FAILED, CANCELLED / equivalent terminal states.
-
-## Repair 6 — bounded `getDiff` output
-
-Symptom:
-
-- Large valid diffs fail with `ResponseTooLargeError` or `GIT_OUTPUT_LIMIT_EXCEEDED`.
-
-Required behavior:
-
-- Do not load unbounded diff text into the Action response.
-- Return bounded summary data: commit identities, changed paths/stats, total bytes, and `truncated: true` when the full patch exceeds the safe limit.
-- If pagination already exists in the contract use it; otherwise prefer deterministic truncation over a breaking schema change.
-- Add tests for small, empty, and oversize diffs.
-
-## Staging deployment procedure
-
-1. Run the existing mandatory test suite before modification; record baseline.
-2. Apply code and config changes only on the governed branch/worktree.
-3. Run focused regression tests.
-4. Run the full mandatory suite.
-5. Build the staging contract overlay using the repository's existing build/deploy path.
-6. Deploy to staging/non-production only.
-7. If systemd units are changed: `systemctl daemon-reload`, then restart only the affected staging services.
-8. Wait for the existing health endpoint/runtime status to become healthy.
-9. Run the acceptance suite below.
-
-If any step fails:
-- collect `journalctl` logs and relevant app logs;
-- diagnose root cause;
-- automatically repair and retry when non-destructive;
-- if a new change breaks staging, restore the previous staging artifact/config and restart the affected service;
-- never silently continue after a failed gate.
-
-## Acceptance suite
-
-All of the following must pass on the same deployed staging overlay:
-
-- Runtime status is `active` and healthy after restart.
-- Gitea Git/API readback works from the runtime service identity.
-- `getReleaseConsistency(V2R2C1, 998d30304787e31e5ae607c0bd86b5edb2b0e5ad, a8b906d1bc24088c19647e98de6a679268f6d0a2, approved_plan) returns a structured result and reaches evaluation.
-- `runReleaseAcceptance` for the same identities reaches policy evaluation, not URL validation error.
-- `getTagPublicationStatus("V2R2C1")` returns structured state, not `invalid release version`.
-- `getReleaseSaga` for a nonexistent candidate returns NOT_FOUND/empty-state semantics, not filesystem permission failure.
-- `commitFilesGoverned` exposes its required `files` parameter in the published Action schema.
- - A real two-file governed commit to an isolated `agent/` branch succeeds and remote branch OID matches.
-- Resuming a COMPLETED job returns the existing `JOB_TERMINAL` semantics or idempotent success as designed.
-- Reconciling a COMPLETED governed job is successful/idempotent and does not require an active lease.
-- Small/empty `getDiff  still works.
-- Large `getDiff` returns bounded output with truncation metadata instead of a transport exception.
-- Existing protected-ref controls remain unchange: no direct main/tag/baseline/production write.
-
-## Restart / reboot persistence
-
-After the first full pass:
-
-- Restart the staging Action/Bridge/release services one more time without changing files.
-- Rerun the acceptance suite.
-- Permissions, Gitea URL, and schema must still be correct after restart.
-- If the repository already has a safe staging reboot test, run it as well.
-
-## Evidence and completion
-
-Create a single durable report in the repository, e.g. `reports/action-contract-repair-evidence-20260825.md`, containing:
-
-- pre-change facts
-- root cause for each regression
-- files changed and why
-- config/permission changes
-- test commands and exact results
-- staging deployment identity (commit/artifact/config digest)
-- restart-persistence results
-- final Action smoke results
-- any remaining risks
-
-Commit all source, test, deployment config, and runbook changes to the governed task branch. Do not mark the task SUCCEEDED until all acceptance gates pass on the actually deployed staging overlay.
-
-## Automatic rollback conditions
-
-Automatically roll back the staging deployment if any of the following occur:
-
-- service fails to become healthy after restart
-- protected-ref write boundary is broken
-- Gitea readback that worked before the change stops working
-- durable saga state cannot be read or recovered
-- mandatory test suite regresses below the pre-change baseline
-
-Do not automatically roll back an existing production release. Rollback here refers only to the staging overlay/service configuration changes made by this task.
-
-## 2026-08-25 execution record
-
-The repair branch was deployed through the existing immutable staging builder. The final source code before the evidence commit was `2ec49005bde44f6981b14351500847d594e0276c`; the deployed artifact was built from that source with SHA256 `f67aed6cc0cce1f08197485c3eea204d3ef4d3989f44dc98e8ea2691e5886cbf`. The final staging drop-ins use a lexically highest `zzzz...-999.conf` layer so they override earlier diagnostic overlays.
-
-The runtime configuration is staging-only: `User=aiman`, `Group=gitops`, API base `https://g.cnnetmkt.top/git/api/v1`, baseline authority `/var/lib/aios-gitops/model-api-staging/baseline/current.json`, and read/write access to the staging state plus the authoritative bare repository required by the governed Writer/CAS path. No `main`, protected tag, baseline registry, or production write is enabled.
-
-The release executor now binds both the configured staging baseline and the immutable runtime package's `versions/V2R2C1.json` projection. The bridge passes `AIOS_GITOPS_BASELINE_AUTHORITY` into `RuntimeConfig`; this prevents release consistency and acceptance from falling back to missing publication-workspace files.
-
-The final acceptance result is recorded in `reports/action-contract-repair-evidence-20260825.md`. Contract smoke is green, and release consistency is `PASS`; release acceptance is structured policy output but remains `accepted=false` because the pre-existing publication state is `REMOTE_PUSH_PENDING` for the protected `V2R2C1` tag. The task must therefore remain `NEEDS_REWORK` until an authorized owner resolves that independent protected-tag state.
-
-## External Action Surface final closure attempt (2026-08-25)
-
-本轮仅部署 staging/non-production；没有直接写入 main�release tag�baseline registry 或 production。
-
-Public route ownership: /api/governed-write-capabilities, /api/control-plane-snapshot, /api/online-agent-task, and /api/online-agent-task-events are exact-location proxied to 127.0.0.1:18890; generic /api/ remains on 127.0.0.1:18893. The durable installer is ops/gitops-migration/bind_external_action_surface_final_staging.sh; it backs up Nginx, runs nginx -t, reloads, and forwards Authorization/X-AIOS-Token.
-
-A task-control token, local Writer grant, Gitea consumer, SSH credential, or old token file is not an external Action bearer. If formal issuance is unavailable, do not print or rotate secrets, enable disabled writes, or manufacture commit evidence; record FORMAL_STAGING_ACTION_BEARER_ISSUANCE_NOT_AVAILABLE. Public release-consistency and release-acceptance use the canonical Bridge v2 evaluator. A Task API continuation remains QUEUED until a legitimate Agent claims it and gives durable result evidence.

-# AIOS 最小自治修复闭环运行手册
-
-## 范围
-
-本手册只覆盖 staging/non-production 的最小链路：
-
-```text
-readRepositoryFile -> acquireWriterLease -> commitFilesGoverned
--> immutable staging build/reload -> runtime/read-back
-```
-
-不覆盖 release/recovery/listPatches 语义，不得写入 `main`、release tag、baseline
-或 production。
-
-## Action contract
-
-公开 Action schema 的 canonical URL 是：
-`https://cnnetmkt.top/api/openapi-chatgpt-actions.yaml`。
-
-本轮增加两个 operation，公开面共 28 个，保留 30 个上限余量：
-
-- `readRepositoryFile`：`POST /readRepositoryFile`，必填 `repository`, `ref`, `path`, `max_bytes`；只从 authoritative bare Git object database 读取，禁止绝对路径、`..`、反斜线、NUL 和 `.git`，单次最多 262144 bytes。
-- `acquireWriterLease`：`POST /acquireWriterLease`，只接受 `CONTINUE_EXISTING`，必须绑定 durable task、repository、target branch、base OID、当前 expected branch OID、generation 和短 TTL。
-- `commitFilesGoverned`：既有 `POST /v2/commit-files`，必须先有同一 task/generation/expected OID 的 lease；`files` 为数组，每项必须含 `path` 与 `content_base64`。
-
-model-api facade 对上述三个入口执行 Action bearer 认证，并把 Authorization/X-AIOS-Token 透传给 loopback Bridge。Bridge 再执行 operation-specific scope：read 允许 `repository:read` 或兼容的 `file:write`，lease 需要 `agent-task:control`，commit 需要 `file:write`。
-
-## 构建与部署
-
-从当前隔离 agent branch 的完整 source OID 构建：
-
-```bash
-python3 scripts/build_v2r2c1_model_api_staging.py \
-  --source-root . \
-  --output-root /var/lib/aios-gitops/bridge-v2-staging/candidate-artifacts/<id> \
-  --source-oid <40-hex-source-oid>
-```
-
-构建 receipt 必须声明 `STAGING`、`aios/aios`、`legacy_global_writes_enabled=false`，并记录 artifact SHA-256。使用 versioned systemd drop-in template，将 source OID、artifact SHA-256 和 immutable runtime path 渲染到 staging 两个 unit；同时使用：
-
-```ini
-LoadCredential=action_tokens:/data/aios-gitops/runtime/secrets/gitops.tokens
-Environment=AIOS_GITOPS_TOKEN_FILE=%d/action_tokens
-```
-
-这样由 systemd 投影已有 Action token registry，不复制或打印 token，不使用 Gitea token 代替 Action bearer。部署后只执行：
-
-```bash
-systemctl daemon-reload
-systemctl restart aios-chatgpt-bridge-v2-staging.service
-systemctl restart aios-gitops-model-api-v2r2c1-staging.service
-```
-
-## 验收顺序
-
-1. `systemctl is-active` 两个 staging unit；读取 `/api/health`、`/v2/runtime`。
-2. 从公网 URL 重新抓取 YAML，解析 operation 数量，确认 `<=30`，并确认 `files`/`path`/`content_base64` required parity。
-3. 使用正式 Action bearer：
-
-```text
-readRepositoryFile(repository, ref=agent/<branch> or exact OID, path, max_bytes)
-acquireWriterLease(task_id, repository, CONTINUE_EXISTING, base_oid,

-5. 验证 staging runtime source OID/artifact SHA-256 与 build receipt 一致，再重复完整 smoke。
-6. 若 bearer 不可用，状态必须是 `BLOCKED`，不能用 SSH、root、Gitea、旧 token、service credential 或 dev bypass 代替。

-只回滚本轮创建的 staging artifact/drop-in；不得回滚 production release。若 health、Gitea readback、protected-ref boundary 或 mandatory suite 回归，恢复前一份 staging drop-in，采集 `journalctl -u` 日志，再继续诊断。
