-# ChatGPT Action schema trust-domain reconciliation
-
-The main source has **31** operations while immutable public runtime `2e5996463de564793df881df5c5f684359733627` serves a different **30**. Both are retained as non-import parity fixtures. Their exact compatible union is **46** operations.
-
-Import only these bounded specs:
-
-- `openapi-chatgpt-actions-governed-release.yaml` — 26 Governed GitOps and Release operations.
-- `openapi-chatgpt-actions-online-gitops-task.yaml` — 14 Online GitOps Task operations.
-- `openapi-chatgpt-actions-online-agent-task.yaml` — 6 actual public Online Agent Task operations.
-
-The machine-readable capability manifest records split schema, server route, declared OpenAPI security, required runtime scope, exposure, and `source_origin` / `public_origin` for every union operation. The dedicated Online Agent Task document includes `createOnlineAgentTask`, `registerOnlineAgent`, `getOnlineAgentTask`, `getOnlineAgentTaskEvents`, `verifyOnlineAgentTask`, and `cancelOnlineAgentTask`; each requires runtime scope `agent-task:control`. Its declared OpenAPI security is copied from the public snapshot without rewrite, while the manifest records the runtime scope separately.
-
-Run `python3 scripts/validate_chatgpt_action_schema_split.py` and `python3 -m unittest discover -s tests -p 'test_chatgpt_action_schema_split.py' -v`. The validator reports `formal_validator=NOT_INSTALLED` rather than a false formal pass if `openapi-spec-validator` is absent.

+# 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.

+# 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.
+
+This repair does not modify FleetScheduler state semantics, capacity, WriterLease, checkpoint,
+protected refs or Production behavior.

+# 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

+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

+provider registry, selection policy, version pinning, budget accounting, fallback, scope isolation,
+credential boundary, trace/audit, evaluation gates and routing resilience.

+# 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.

+# R4.2 P0-A TaskPlane Scope Isolation
+
+Status: candidate implementation. This is not proof of protected-main promotion or production deployment.
+
+Task scope is now represented by `scope_type`, `tenant_id`, `user_id`, `project_id`, `conversation_id`, and `run_id` in the model and SQLite persistence. Historical rows become `legacy`; their tenant is never guessed. Tenant tasks require `tenant_id`. System resources use `scope_type=system` without a fabricated tenant.
+
+The HTTP adapter uses the authenticated identity. `PolicyEngine` resolves that identity through server-owned `identity_actor_contexts`; request payload fields do not grant scope. Public create binds the trusted scope, and public list/get apply parameterized scope predicates in `TaskPlaneStore`.
+
+SQLite is the current runtime database. PostgreSQL remains a separate migration and runtime-acceptance gate.

+# R4.2 P0-B — Durable Message / Handoff Fabric
+
+Status: candidate implementation; not evidence of protected-main merge or Production deployment.
+
+`MessageEnvelope` is the single durable handoff identity and carries source/target/type, tenant/user/
+project/conversation/task/run scope, causation, sequence, capability scope, confidentiality scope,
+idempotency key, expiry and delivery state.
+
+Identity includes **target + scope + sequence + idempotency key + payload hash**, fixing the existing
+AgentEventBus target collision. Server ActorContext is authoritative; caller scope may narrow but may
+not widen/forge trusted tenant/user/project/conversation/run fields.
+
+`DurableHandoffStore` provides SQLite durability in the current runtime. Each logical stream has
+unique `(stream_key, idempotency_key)` and `(stream_key, sequence)`. Exact retry returns `REPLAY`;
+changed payload under the same key is rejected; sequence gaps are rejected; expired messages are not
+delivered.
+
+Confidentiality scopes:
+
+- public: no tenant requirement
+- tenant: same tenant
+- project: same tenant + project
+- private: same tenant + project + user
+- run: same tenant + project + user + run
+
+Required `capability_scope` must be present on the authenticated delivery actor unless the actor is
+explicitly administrative.
+
+Compatibility adapters convert AgentEventBus events, TaskPlane CloudEvents and legacy Agent OS
+MessageBus messages into the durable envelope. Existing message_outbox remains intact as a migration
+source; P0-B does not delete or silently rewrite it.
+
+Required gates:
+`MESSAGE_SCOPE_MISMATCH_DENY`, `MESSAGE_TARGET_COLLISION_DENY`, `MESSAGE_IDEMPOTENCY_REPLAY`,
+`MESSAGE_SEQUENCE_GAP_DETECT`, `MESSAGE_CONFIDENTIALITY_SCOPE_ENFORCE`,
+`HANDOFF_CROSS_TENANT_DENY`, plus existing P0-A TaskPlane scope/security regressions.
+
+SQLite remains current runtime persistence. PostgreSQL remains a separate migration gate.
