agent: baseline 1.1 evidence materialization + builder readiness split

Separate Builder readiness (infrastructure-only) from build (recipe-evidence
gated). Add Evidence Materializer (validator/projector, never invents release
evidence). Unify Source Admission policy digest to exact policy file SHA-256
through one helper/constructor. Add HMAC-audited isolated-peer policy rebind.

Base: 2852c2a403 (exact)
Files: 10 (6 modified + 4 added), +1513/-40
Patch SHA-256: 85be2b4e369a7d39eba0f7b7f1c2641a9eabdf0276d4d48d371cfc348465ed51

-"""aios_owner_based_executor — Owner 基于授权的可执行 CLI 入口。
-
-把 "owner 基于授权 → Agent 自主完成受治理写链" 从测试/装配层提升为**可直接执行的命令**。
-集成 V2R2C3 现场组合根 `field_governed_writer.py`，装配到生产入口
-`GovernedWriterAutomation.acquire_verified()`。
-
-子命令：
-  register <authorization_ref>  登记一条 Owner 授权到 authority（可 --policy-json 指定，
-                                 默认用内置参考授权物 azn-owner-gw-v1）。
-  acquire <authorization_ref>   装配 FieldGovernedWriterFactory，运行 acquire_verified()，
-                                 输出 GovernedWriterSession JSON。
-
-行为契约：
-- 生产入口唯一授权来源是 authority 已登记的 authorization_ref；未登记即 fail-closed。
-- authority 未装配（--no-authority 或构造时 owner_authority=None）→ AuthorizationDenied。
-- EXPIRED 任务无预签 recovery → OwnerActionRequired（OWNER_BOUNDARY，非自动恢复）。
-- status==error 输出到 stderr，退出码非 0；成功输出会话 JSON，退出码 0。
-- legacy_global_writes_enabled 默认 false = 安全不变式，不是 blocker。
-
-用法示例：

-is derived from real build artifacts and real verification executions supplied as

-- input         : governed build artifacts + deployment conventions (no hand-write)
-- output        : source_root/<version>/ full evidence_layout closure + receipt.json

-"""AIOS-native binding layer for the unattended resume controller.
-
-This module intentionally contains no HTTP client, Unix-socket client, database,
-systemd integration, scheduler loop, secret handling, or privileged identity
-mutation.
-
-It converts existing AIOS authorities into the generic callbacks defined by
-``autonomous_resume_integration``. Field code supplies the current authoritative
-implementations for:
-
-- durable Owner authorization/grant projection;
-- canonical governed-worker activation/status;
-- governed task admission;
-- task/claim/TaskLease/TaskPrincipal/WriterLease/CAS ownership;
-- bounded source-lane execution and integration;
-- Gate0;
-- ReleaseReady/deployability;
-- PromotionController;
-- final production acceptance;
-- mission resume lease/checkpoint/effect reconciliation.
-
-The adapter is deterministic and fail-closed. It never fabricates any credential,
-principal, lease, fence, task, commit, receipt, approval, or deployment result.

-"""Deterministic unattended mission-resume controller for AIOS.
-
-The controller is deliberately small and does not create a second scheduler,
-database, identity system, or release control plane.
-
-It executes exactly one reconciliation/progress cycle per ``run_once`` call.
-An existing AIOS scheduler/timer/worker loop should invoke it periodically.
-
-All consequential effects are delegated through ``AutonomousExecutionPort`` and
-must use the existing AIOS authorities: durable Owner authorization, task
-admission, claim/TaskLease/TaskPrincipal, WriterLease/CAS/fencing, Gate0,
-ReleaseReady, PromotionController and governed rollback.
-
-The controller's responsibilities are limited to:
-- one-winner resume lease acquisition;
-- durable checkpoint progression;
-- bounded retry/backoff;
-- unchanged deterministic blocker suppression;
-- UNKNOWN/ambiguous-effect reconciliation before retry;
-- non-interactive owner-boundary recording;
-- crash-safe phase resumption.
-
-It never manufactures credentials, group membership, principals, leases,
-signatures, branch OIDs, or release receipts.

-1. 生产入口唯一授权来源是 Owner 登记的 `authorization_ref`；Agent 本地自造的
-   `OwnerAuthorizationPolicy` 不构成 proof（fail-closed）。
-2. 长期业务授权（Policy）与短时执行凭证（epoch/lease/principal）分离。
-3. `legacy_global_writes_enabled=false` 是安全不变式，不是 governed-writer blocker。

-"""Fail-closed host adapter for the C6 governed source-patch pilot.
-
-The adapter owns no worker registration, authority database, effect ledger, or
-Git mutation implementation.  Those are host-owned.  It only joins an exact C6
-operation binding and v3 TaskPlane claim to an existing durable external
-transaction owner.
-
-The transaction owner is a security boundary.  Its ``execute_prepared`` method
-must durably record the send phase before an external call, call
-``before_external_call`` while holding its own lease/fence, acquire and persist
-the real WriterLease, enforce expected-OID CAS at the write linearization point,
-and leave an ambiguous call in EFFECT_UNKNOWN.  A callback by itself is not an
-atomic revocation or CAS fence.
-
-``RootActionConsumer`` exposes an exact-key facade only after the host installs
-a trusted operation-to-review binding provider.  C6 callers cannot synthesize
-review_id, mission_id, root_task_id, root_revision, plan digest, or execution
-key.  The facade reuses the consumer's existing review, fence, and effect rows.
