-- Task: `r42-p0a-taskplane-scope-isolation-20260816`
-- Governed Job: `job-3fd743b51971c6007923699c1233f84c`
-- Repository: `aios/aios`

-- 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,

-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.

-# 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.

+# Server-local governed immutable Host seed executor
+
+Date: 2026-08-22
+
+## Goal
+
+Provide a server-local, fail-closed way to publish an already validated
+immutable control-plane candidate without depending on Windows, an external
+Agent worker, SSH, or an arbitrary root command channel.
+
+The executor is deliberately narrower than deployment:
+
+- it reads only the authoritative local Git object database;
+- it consumes one fixed request ref and path;
+- it accepts only `HOST_SEED_IMMUTABLE_CANDIDATE`;
+- it requires a high-risk governed-task binding whose description binds the
+  exact candidate intent *and* authorization expiry;
+- it materializes `base_oid + candidate.patch`, verifies every release-member
+  SHA against the candidate manifest, and verifies the candidate Machine Goal;
+- it atomically publishes one immutable directory under `/opt/aios/releases`;
+- it never starts or restarts services, starts the Projector, creates the fixed
+  continuation Task/Job, switches Production, or writes `main`, tags, or the
+  baseline.
+
+## Canonical server path
+
+```text
+explicit Owner HOST_SEED authorization
+  -> high-risk governed authorization task binding
+  -> governed request commit on refs/heads/agent/host-seed-authorization-requests
+  -> root timer polls local authoritative Git
+  -> validate exact intent, expiry, binding SHA, candidate evidence
+  -> read payload commit from local Git
+  -> shared disposable clone at exact base
+  -> apply declared patch
+  -> verify exact changed set + all release-member bytes
+  -> atomic immutable publish
+  -> durable sanitized receipt
+```
+
+The Host seed request is not the fixed continuation Task. The fixed
+continuation Task remains a separate later gate.
+
+## Trust and authorization binding
+
+The request contains an immutable `intent` with:
+
+- candidate / release id;
+- base OID and payload commit;
+- fixed patch, manifest, Machine Goal and bootstrap paths;
+- validation artifact SHA;
+- Manifest, Machine Goal, release-tree and bootstrap SHAs;
+- exact target Host identity.
+
+`intent_sha256` is the canonical SHA of that object. Authorization adds
+`task_id` and `expires_at`; those are hashed into `authorization_sha256`.
+The server-side governed-task binding must contain:
+
+```text
+risk=high
+description=HOST_SEED_AUTHORIZATION:<authorization_sha256>
+target_branch=agent/host-seed-authorization-...
+```
+
+The request also binds the exact byte SHA of that server-side binding. This
+prevents extending the authorization window or changing the candidate without
+creating a new governed authorization binding.
+
+The executor additionally requires the binding file to be a non-symlink
+regular file, not group/world writable, and owned by the configured Bridge
+service account in production.
+
+## Delivery model
+
+The live delivery payload is server-native Git data, not the external ZIP.
+The payload commit carries:
+
+```text
+control-plane/candidates/<candidate>/candidate.patch
+control-plane/candidates/<candidate>/implementation_manifest_*.json
+control-plane/candidates/<candidate>/machine_goal_*.json
+control-plane/candidates/<candidate>/aios_control_plane_immutable_seed_*.py
+```
+
+The external ZIP SHA remains bound as validation evidence through Machine
+Goal, but the executor records `artifact_delivery_used=false`: it does not
+claim that ZIP bytes were copied to the Host.
+
+The release tree itself is reconstructed and verified from authoritative Git
+objects plus the declared patch.
+
+## Idempotency and recovery
+
+Before publishing, the executor writes a durable `PENDING` operation record
+keyed by the exact intent SHA. The final receipt is `EXECUTED`.
+
+If the immutable release directory already exists, every member must match the
+manifest before the operation is accepted as idempotent. Any drift fails
+closed.
+
+A missing request ref is a normal `NO_REQUEST` poll and has no side effects.
+
+## Systemd confinement
+
+The service:
+
+- runs as root only because immutable release publication requires it;
+- has no network access;
+- reads authoritative Git and Bridge task bindings read-only;
+- can write only its private state root and `/opt/aios/releases`;
+- has no service-control, Projector, Task, Git-ref, Production, tag or baseline
+  operation in its code path.
+
+The timer polls every 30 seconds. Installing/enabling this executor is itself a
+separate governed control-plane deployment. Installing it does **not** grant a
+Host seed authorization and does not seed any candidate while the fixed
+request ref is absent.
