-The guard never claims Tasks and never writes Task/Job/Git databases. It only:
-- ensures required worker/executor systemd units are enabled + active;
-- checks worker-owned liveness JSON written by the real poll/heartbeat loop;
-- restarts an active worker only when its liveness is stale;
-- honors an explicit maintenance inhibit file;
-- writes a bounded status JSON under /run for observability.

+# Autonomous Intent Worker v2
+
+## Goal
+
+A Custom GPT or other trusted producer creates a prose engineering task with:
+
+- `goal`
+- `instructions`
+- `success_criteria`
+- `required_capabilities`
+
+A long-running autonomous worker claims only tasks explicitly marked with:
+
+- `intent.task`
+- `engineering.execute`
+
+and only when the requested engineering runtime capability is actually
+available, e.g. `agent.runtime.hermes`.
+
+The runtime edits a disposable worktree. The worker independently inspects the
+diff, scans for secrets, reruns verification, and persists through staging
+Governed GitOps.
+
+## Security domains
+
+The Online Agent worker owns task/lease/governed-write credentials.
+
+The runtime broker is a separate service identity. It authorizes the worker
+over Unix `SO_PEERCRED`, opens the worktree using `O_PATH|O_NOFOLLOW`, and
+passes a pinned `/proc/self/fd/<fd>` path to the engineering backend. The
+backend never receives the Agent Task token or writer lease.
+
+The worker rejects:
+- a runtime-created Git commit (`HEAD != base_oid`);
+- direct authoritative ref mutation/push;
+- sensitive credential/key paths;
+- obvious secret material;
+- non-staging Governed Bridge endpoints.
+
+## Staging boundary
+
+`autonomous_worker.py` intentionally rejects any Governed Write API base other
+than:
+
+`http://127.0.0.1:19998`
+
+Production/main/tag/baseline/force-push writes remain outside this worker.
+
+## Migration protection
+
+The worker does not infer intent from prose. Historical tasks without
+`intent.task` are skipped before claim, so they do not lose an attempt.
+
+The bootstrap task
+`implement-autonomous-intent-worker-v2-20260815` currently lacks the intent
+marker and is therefore intentionally not claimable by this worker. That is a
+control-plane/bootstrap concern, not a reason to weaken the runtime rule.
+
+## Runtime requirement
+
+A chat/WeChat Hermes endpoint is not enough. A compliant engineering backend
+must:
+1. accept `aios.online-agent.runtime-request.v1`;
+2. inspect and mutate the supplied disposable worktree;
+3. leave Git HEAD unchanged;
+4. return `aios.online-agent.runtime-result.v1`.
+
+The exact installed Hermes/Codex interface is host-specific and must be
+discovered before configuring the broker. No CLI flags are invented here.
+
+## Activation gate
+
+Do not register or enable the autonomous consumer until:
+1. a real engineering backend is found;
+2. broker is configured with that backend;
+3. `runtime_selftest.py` reports PASS;
+4. backend has no Agent Task token or writer lease.
+
+After activation, complete D/E/F/G:
+- D: native intent task, no `metadata.execution`;
+- E: goal-only engineering task, runtime finds files/root cause;
+- F: unavailable runtime capability remains unclaimed;
+- G: restart during real runtime execution, no duplicate commit/branch.
+
+
+## OpenClaw backend candidate
+
+A current OpenClaw installation can be used as an autonomous engineering
+runtime without making OpenClaw itself an AIOS Task API client.
+
+The bundled wrapper uses the official headless coding entry point:
+
+```text
+openclaw agent exec
+  --message-file -
+  --cwd <pinned-disposable-worktree>
+  --model <verified-provider/model>
+  --auth-env-only
+  --timeout <seconds>
+  --json
+```
+
+Reference used for implementation:
+`https://docs.openclaw.ai/cli/agent`
+
+The wrapper maps the stable OpenClaw JSON envelope into
+`aios.online-agent.runtime-result.v1`. The AIOS worker remains responsible for
+claim/heartbeat, independent diff verification and Governed GitOps.
+
+OpenClaw is advertised as `agent.runtime.openclaw`, not as Hermes or Codex.

-# R4.2 P0-A TaskPlane Scope Isolation Design
-
-Status: approved candidate design. This document is not evidence of a protected-main merge or production deployment.
-
-## Boundary
-
-- Task: `r42-p0a-taskplane-scope-isolation-20260816`
-- Governed Job: `job-3fd743b51971c6007923699c1233f84c`
-- Repository: `aios/aios`
-- Base: `0eb6e1a864edfdaeef37b438991707a110e21558`
-- 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.

-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.
-
-This repair does not modify FleetScheduler state semantics, capacity, WriterLease, checkpoint,

-# R4.2 P2-B Fleet Runtime Integration
-
-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
-canonical `source_capture` action and `compact_interface_map` adapter, but selects a bounded semantic
-profile from the task's source signals.
-
-The existing `fleet` profile remains backward compatible and returns
-`P2_INTERFACE_MAP_CAPTURED` with the `FLEET_*` contracts.
-
-The new `model_governance` profile is selected when model/provider/routing/budget/evaluation terms
-are present. It returns `MODEL_GOVERNANCE_INTERFACE_MAP_CAPTURED` and model-specific contracts for
-provider registry, selection policy, version pinning, budget accounting, fallback, scope isolation,
-credential boundary, trace/audit, evaluation gates and routing resilience.
-
-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.
-
-No new Bridge action, daemon, database, WriterLease, mutation path or credential surface is added.

-# 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
-
-## Purpose
-
-`aios_agent_task_execution_rebind.py` closes a projection/plan race without replacing the Task,
-Governed Job, target branch, generation, or idempotency lineage.
-
-The only supported transition is:
-
-```text
-official NEEDS_REWORK
-→ Task QUEUED with no active lease
-→ persisted source_capture envelope
-→ canonical Bridge resolves an already-registered deterministic plan
-→ CAS-bound metadata.execution + execution_projection replacement
-→ audit event
-→ normal worker claim
-```
-
-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.

-# AIOS Worker Availability Runtime
-
-## Priority
-
-This runtime exists to make the already verified Online Agent execution path continuously usable
-without repeated human intervention.
-
-The system already proved that generic, Hermes and OpenClaw workers can claim and complete real
-Online Tasks. The remaining availability defect was operational: evidence-freeze workflows left the
-worker services stopped, while registry `ACTIVE` records remained stale.
-
-The availability contract therefore separates:
-
-```text
-AUTO_CLAIM_MECHANISM=VERIFIED
-CURRENT_WORKER_AVAILABILITY=<fresh runtime state>
-```
-
-A historical successful claim is not current liveness.
-
-## Source of truth for idle liveness
-
-An idle worker may have no Task lease heartbeat. Therefore Task heartbeat alone cannot prove that
-the worker is continuously polling.
-
-`aios_online_agent_worker.py` now writes:
-
-```text
-<AIOS_WORKER_STATE_ROOT>/worker-liveness.json
-```
-
-on:
-
-- process start: `STARTING`;
-- every successful poll: `POLL_OK`;
-- poll failure: `POLL_FAILED`;
-- every successful Task lease heartbeat while executing: `BUSY`.
-
-The file contains:
-
-- agent ID/type/version;
-- process PID;
-- monotonically increasing local sequence;
-- `last_seen_epoch`;
-- poll/heartbeat intervals;
-- current Task/stage while busy.
-
-The liveness file is worker-owned observability state only. It does not write or mutate Task, Job,
-Git, WriterLease or registry databases.
-
-## Self-healing guard
-
-`aios-worker-availability-guard.timer` invokes a root-owned oneshot guard every 30 seconds.
-
-The guard manages:
-
-```text
-aios-online-agent-worker-20260815.service
-aios-hermes-online-agent-worker.service
-aios-openclaw-online-agent-worker.service
-```
-
-and the required external runtime dependency:
-
-```text
-aios-external-agent-executor.service
-```
-
-For each worker:
-
-1. missing systemd unit → fail closed;
-2. disabled → `systemctl enable`;
-3. inactive → `systemctl start`;
-4. active but liveness older than 90 seconds → restart;
-5. repeated stale restart within 60 seconds → do not restart again; report degraded.
-
-Long-running Tasks are safe because the Task lease-heartbeat thread refreshes `BUSY` liveness.
-
-The guard never claims a Task and never touches Task/Job/Git databases.
-
-## Maintenance inhibit
-
-Planned maintenance creates:
-
-```text
-/run/aios-worker-availability/maintenance.lock
-```
-
-While this file exists the guard performs no start/restart actions and reports:
-
-```text
-MAINTENANCE_INHIBITED
-```
-
-Maintenance tooling must remove the file when done. This prevents the self-healer from fighting
-intentional service changes.
-
-## Status
-
-The guard writes:
-
-```text
-/run/aios-worker-availability/status.json
-```
-
-with current worker/dependency states, liveness ages and recovery actions.
-
-A worker is currently available only when:
-
-```text
-systemd load_state=loaded
-systemd active_state=active
-unit enabled/static
-worker-liveness.json present
-last_seen_age <= 90s
-```
-
-Registry `ACTIVE` without fresh poll/busy liveness is not sufficient.
-
-## Boot/restart behavior
-
-The timer is:
-
-```text
-OnBootSec=15s
-OnUnitActiveSec=30s
-Persistent=true
-```
-
-Therefore reboot, manual stop left behind by another workflow, process crash, and hung poll loop are
-all repaired without requiring a human to notice and intervene.
-
-Normal worker units retain their own `Restart=always`; the availability guard handles the cases that
-`Restart=always` cannot, especially a deliberate `systemctl stop` left after an evidence workflow.
-
-## Acceptance
-
-The live acceptance requires all of the following:
-
-```text
-guard timer active/enabled
-external executor active/enabled
-generic worker active/enabled + fresh liveness
-Hermes worker active/enabled + fresh liveness
-OpenClaw worker active/enabled + fresh liveness
-```
-
-Then a new read-only Online Task is projected through canonical Bridge `18892`.
-
-Success requires:
-
-```text
-TASK_CREATED
-→ generic worker auto claim
-→ TASK_HEARTBEAT
-→ RESULT_SUBMITTED
-→ official TASK_VERIFIED(SUCCEEDED)
-```
-
-After the Task, the services must remain active and liveness must continue advancing. The acceptance
-also stops a worker intentionally once and proves the guard starts it again with a new fresh
-liveness sequence.
-
-Only after these gates may current status be upgraded from:
-
-```text
-OVERALL=PARTIAL
-```
-
-to:
-
-```text
-PERSISTENT_WORKER_LIVENESS=VERIFIED
-NEW_TASK_AUTO_CONSUMPTION=VERIFIED
-WORKER_AVAILABILITY_RUNTIME=VERIFIED_CANDIDATE
-```
-
-Protected main and Production remain out of scope.
-
-
-## Forced source-capture projection compatibility
-
-The deployed canonical Bridge currently projects a default `source_capture` envelope even when a
-governed binding request asks for binding-only behavior. This must not be allowed to make always-on
-workers consume engineering Tasks before their deterministic plan is registered.
-
-The worker therefore distinguishes a real read-only source capture from an engineering placeholder:
-
-```text
-source_capture
-+ capability_scope contains governed.write.branch or governed.write.file
-= PENDING_DETERMINISTIC_PLAN
-```
-
-For such a placeholder the worker:
-
-1. re-resolves through the canonical plan registry **without replaying the stale source-capture
-   envelope**;
-2. if no deterministic plan exists, emits `TASK_SKIPPED_PENDING_DETERMINISTIC_PLAN` and does not
-   claim;
-3. if the registered canonical envelope is deterministic and the governed binding still matches,
-   uses that deterministic envelope and claims normally.
-
-A real read-only source-capture Task with only `git.read`/`git.test` still replays its exact persisted
-payload and remains claimable.
-
-This makes persistent workers safe with the currently deployed Bridge while preserving the same
-Task/Job binding. No Task DB rewrite, cancellation, replacement Task, fake NEEDS_REWORK, or
-pre-claim metadata mutation is required.
-
-A later Bridge cleanup may implement true binding-only projection, but Worker Availability does not
-depend on that cleanup.

+# Autonomous Engineering Runtime Contract v1
+
+The Online Agent Worker and the Hermes/Codex engineering runtime are separate
+security domains.
+
+The worker owns:
+- Agent Task polling, atomic claim, task lease and heartbeat;
+- intent resolution and restart state;
+- authoritative repository/base selection;
+- independent diff inspection and secret checks;
+- verification command allowlisting and re-execution;
+- Governed GitOps task/lease/commit;
+- final result submission.
+
+The runtime broker and Hermes/Codex backend do **not** receive:
+- Agent Task API token;
+- task lease token;
+- governed writer lease or Bridge credential;
+- authority repository write access.
+
+## stdin request
+
+The backend configured behind the broker receives one JSON object:
+
+`schema = aios.online-agent.runtime-request.v1`
+
+It contains task goal/instructions/success criteria and a pinned disposable
+worktree path. The backend may inspect and modify that worktree. It must not
+commit or push.
+
+## stdout response
+
+The backend returns one JSON object:
+
+```json
+{
+  "schema": "aios.online-agent.runtime-result.v1",
+  "status": "COMPLETED",
+  "summary": "root cause and implementation summary",
+  "verification": [
+    {
+      "label": "focused test",
+      "argv": ["/usr/bin/python3", "-m", "pytest", "-q", "tests/test_x.py"],
+      "cwd": ".",
+      "timeout_seconds": 600
+    }
+  ],
+  "evidence": {
+    "root_cause": "..."
+  }
+}
+```
+
+`status` may also be `BLOCKED` or `FAILED`.
+
+The worker ignores any backend claim about changed files and independently reads
+Git state. It also reruns verification requests through its local command
+allowlist.
+
+## Real runtime requirement
+
+A chat/router/WeChat Hermes service is not an engineering backend. A compliant
+backend must be able to read and mutate the disposable worktree and emit the
+runtime result schema above.
+
+The exact Hermes/Codex CLI/API must be discovered from the installed runtime.
+Do not invent flags. `/etc/aios/agent-runtime-hermes.conf` contains only
+non-secret backend command configuration. Any model/runtime credential must be
+delivered to the broker/backend through its own systemd credential projection,
+never through the Online Agent worker token.
+
+
+## OpenClaw headless engineering backend
+
+For hosts that have a current OpenClaw CLI, use the bundled
+`openclaw_engineering_backend.py`.
+
+The wrapper invokes the documented headless coding entry point:
+
+`openclaw agent exec --message-file - --cwd <pinned-worktree> --model <model> --auth-env-only --timeout <seconds> --json`
+
+It deliberately does **not** use the Gateway/WeChat/chat route. `agent exec`
+runs an embedded, one-shot agent turn and scopes its workspace/tool working
+directory to `--cwd`.
+
+Provider credentials, if required, are projected into the broker service under
+separate systemd credentials and mapped to provider environment variables only
+for the OpenClaw child. The Online Agent Task token and writer lease remain
+absent.
+
+Before enabling the autonomous worker, run a disposable broker self-test that
+proves OpenClaw changes the requested worktree while Git HEAD remains at the
+base OID.

+# Generic Governed Online Agent Worker
+
+This worker is a pull-based, restartable consumer for `aios.agent-task.v1`.
+The service configuration contains only stable runtime identity, capability
+names, API endpoints, heartbeat timing, and the credential projection. It does
+not contain a task id, repository base OID, target branch, or plan-file path.
+
+## Dynamic task contract
+
+Engineering tasks carry `metadata.execution` with schema
+`aios.online-agent.execution.v2`. The payload supplies the repository, exact
+base OID, target branch, detached-worktree policy, adapter name, explicit file
+change set, verification commands, and governed commit idempotency keys.
+Task prose is descriptive only and is never passed to a shell.
+
+The worker accepts only structured operations:
+
+- `deterministic`: allow-listed file changes and test commands;
+- `codex`: fail-closed until a task supplies an explicit Codex file/command
+  policy;
+- `hermes`: fail-closed because the current Hermes runtime is a user-chat
+  service, not an engineering executor.
+
+All command execution uses `shell=False`, fixed program allowlists, relative
+paths beneath an ephemeral detached worktree, and output redaction. Direct
+`git branch`, `update-ref`, `push`, `commit`, `reset`, `clean`, main,
+production, tag, and baseline mutations are rejected by the worker.
+
+## Governed write path
+
+The worker calls the Bridge in this order:
+
+1. `POST /v2/governed-task`;
+2. `POST /v2/writer-lease`;
+3. `POST /v2/commit-files`;
+4. read-only authority-ref visibility verification.
+
+CREATE_NEW is represented by the task payload and is normalized by the Bridge
+lease authority. The worker never creates an authoritative ref itself.
+
+## Lifecycle and recovery
+
+The runtime registers with `register_or_recover`, receives its agent token
+once, and stores only the encrypted systemd credential. The consumer loops over
+poll, atomically claims one task, sends the first heartbeat, emits
+`TASK_STARTED`, and continues heartbeats while executing.
+
+State is atomically stored per task without agent or lease token material. If
+the process stops after a governed commit but before result submission, the
+next lease attempt reuses the stable governed idempotency key and submits the
+stored commit evidence without issuing a second commit.
+
+The control plane must independently verify submitted results; worker-local
+success is not production or mainline authorization.

+The worker is deliberately task-agnostic.  A task's signed/durable payload is
+the only source of repository, branch, change, verification, and governance
+parameters.  There is no task id, base OID, branch name, or plan file in the
+runtime configuration.
+
+The worker performs local work only in an ephemeral detached worktree.  All
+authoritative ref updates go through the governed Bridge API; direct branch,
+update-ref, push, main, production, tag, and baseline mutations are rejected.
