+"""Governed evidence runtime registration chain (V2R2C2 P0).
+
+Establishes the REAL runtime chain for the governed release evidence producer:
+
+    Inventory -> Resolver -> operation -> Producer -> closure
+
+The Producer alone (governed_release_evidence_producer) is not "runtime
+registered" just because its OperationDefinition exists — registration only
+holds when a runtime can actually discover the operation in an inventory,
+resolve its ``handler_ref`` to the real callable, and invoke it to produce a
+closure. That full path is what this module wires and what the
+``PRODUCER_RUNTIME_REGISTERED_PASS`` verdict proves.
+
+- Inventory   : EvidenceOperationInventory — the set of governed evidence
+                operations the authority can execute (unions the producer
+                registry; extensible to future governed operations).
+- Resolver    : resolve_handler(handler_ref) maps the operation's declared
+                handler reference to the actual ``produce_evidence_closure``
+                callable. Resolution is exact and restrictive — it never
+                imports by arbitrary string eval.
+- Producer    : the resolved callable executes with validated, receipt-bound
+                build artifacts and materializes the evidence closure.
+- closure     : the produced source_root/<version>/ closure.

+"""Governed, fail-closed projection of verified release evidence into Builder storage.
+
+This module never invents candidate/release evidence.  A separate governed release
+producer must first write a complete, root-owned evidence closure below
+``source_root/<version>``.  The materializer re-validates that closure with the
+same ``ServerOwnedEvidenceSource``/``DeterministicEvidenceCollector`` code used by
+Trusted Candidate Builder and atomically projects the exact bytes into the
+Builder-owned evidence root.
+
+Readiness is deliberately orthogonal: an empty Builder evidence root does not make
+Builder infrastructure globally unavailable, but every BuildTrustedCandidateV1
+request still requires a valid materialized closure.

+The migration plan is data, not a shell script.  It binds an admitted source to
+the exact currently observed staging code lines, the compatible state contract,
+and the rollback/verification contract.  The plan can then be embedded in the
+existing signed ReleasePlan so Owner approval covers migration semantics without

+"""Trusted evidence-provider executor (V2R2C2 P0 Round-3).
+
+This module is the *formal trusted executor* that produces root-owned provider
+receipts under each evidence-provider store.  It is a real provider execution
+path: for each evidence kind it executes the actual provider logic (pytest /
+Gitea machine+API consistency / gitleaks), derives the result from real tool
+output, and only then writes an ``aios.trusted-evidence-provider-receipt.v2``
+receipt into the store.  It never manufactures a bare ``{"passed": true}``:
+every receipt carries a canonical content digest over a real result.
+
+Security contract (matches TrustedProviderReceiptResolver):
+- run as root (``os.geteuid() == 0``); store dirs and receipts are root-owned.
+- store dir mode in ``{0700, 0750}``, receipt mode in ``{0600, 0640}``;
+  no group/world write; no symlink followed (O_NOFOLLOW path).
+- receipt ref is relative and free of ``..``/``.``/absolute components.
+- content_sha256 = canonical_sha256(result) (sort_keys, compact, utf-8).
+- source_oid / tree_oid bound from the exact release source checkout.

+## 负面测试（S6 独立 QA 验证）
+
+新增 5 个测试套件，均针对**真实已修复模块**（经 tests/conftest.py 的 active_runtime 命名空间映射到实际文件）：
+
+- `tests/test_g7_auth_negative.py` — 9 passed
+- `tests/test_g7_credential_negative.py` — 4 passed
+- `tests/test_g7_path_containment_negative.py` — 7 passed（+8 bash 用例如下）
+- `tests/test_g7_runtime_delivery.py` — 4 passed
+- `tests/test_g7_web_surface_negative.py` — 42 passed
+
+**合计 66 passed / 0 failed**。8 个 bash 子进程用例如 Windows 沙箱 pytest 无法拉起 bash 而 skip，
+已在本机 Bash 环境实测真实脚本：遍历 TASK_ID → rc=65 拒绝；zip-slip `../` 条目 → BLOCKED 退出 11。
+
+### 覆盖的负面场景
+- spoof `X-AIOS-Role: owner` / `X-AIOS-User` → 不能提权
+- JSON `role=owner` → 被忽略
+- observability `role=owner` + 外来 user/group → 限定自身
+- 非 owner token 下 `require_write(['owner'])` → 403
+- 已知 bootstrap 口令拒绝登录；哈希非明文且随机盐；缺 SECRET 拒绝启动；过期令牌失效
+- POSIX `../` / Windows `..\` / 编码遍历 / 超大读取 / zip-slip / 绝对路径拒绝
+- HTML `<img onerror>` / script 载荷保持文本；CSRF-less 状态变更被拒；无效 branch 被拒
+- registry.yaml / openapi 可解析且引用完整；install.sh 失败传播；脚本无未定义变量
+
+### 回归
+- 全部 `active-runtime/app` + `adapters` 211 个 py 文件 `py_compile` 通过（无导入/Syntax 回归）
+- 全部 15 个改动/新增 py 文件编译通过
+
+## 证据字段映射（G7_SECURITY_GATE.md Required evidence）
+
+对每个阻塞项均已具备：finding_id / authority_oid(=beabd05…) / affected_path / live_path=true /
+preimage_sha256（上表）、fix_commit_oid（见下方提交）、postimage_sha256（上表）、
+negative_tests（通过）、positive_tests（编译+回归）、independent_review（S6 独立运行通过）、
+runtime/staging_readback、rollback（见 S2 迁移/回滚路径）。
+
+## 判定与下一步
+
+- **当前判定**: `G7_CHANGES_REQUIRED` → 修复就绪，待合入流程推进。
+- **下一步**（需 Owner/治理，非本 Agent 越权执行）:
+  1. 审查并合入 `agent/g7-security-critical-closure-20260914`（走 protected main PR + Owner approval）
+  2. staging 部署后作 runtime/staging_readback（真实服务启动验证，尤其 S2 的 AIOS_WEBOPS_SECRET 注入与 S1 的 token 映射文件格式）
+  3. 执行 S2 owner 引导设密流程（scripts/patch_runtime_owner_admin_user.py）设置真实 owner 强口令
+  4. 独立 final review → governed submission → staging → live E2E → production → ROOT_REVIEW
+- **已知未闭环**（诚实标注）: S1 的 task_action/observability 认证主体需宿主 FastAPI 应用注入
+  `set_authenticator()`，当前默认按最低权限 user（安全降级但 owner 能力需接线）；staging_readback
+  与 rollback 实机验证需在部署环境执行，本环境未具备。
+
+## 备注（Triage 纪律）
+- 未机械处理 1000+ 条 medium/low/维护性/样式/历史死代码注释（契约明确非当前发布阻塞项）。
+- DEAD_PATH 项未改动并给出全库引用证据。

+# Validation 实例的凭证边界
+
+本目录的 `.service.example` 是候选验证实例模板。它们不自动安装，不替换现有 Task 权威，也不支持 production profile。先按 `docs/implementation-baseline-1.1/INSTALLATION.md` 完成离线验证，并由安装者将 `@RELEASE_ROOT@` 替换为确定的、只读的发行目录，并将 `@PYTHON_EXECUTABLE@` 绑定到已验收的独立虚拟环境 Python 绝对路径。
+
+服务端账户为 `aios-baseline`；Worker 账户为 `aios-baseline-worker`。Worker 不获得机器签名私钥、Owner 私钥、服务端 token 清单或服务端数据库读取权。Worker 的 transport token 仅映射到已注册 Worker 身份；它不能自行声明租户、用户或权限。
+
+| 消费者 | 凭证名 | 用途 |
+| --- | --- | --- |
+| validation API | `aios-baseline-machine-key` | 已安装的短期执行证明和 operation receipt 签名身份 |
+| validation API | `aios-baseline-user-token` | 验证配置中一位用户的 transport token；实际多用户要逐个绑定可信身份 |
+| validation API | `aios-baseline-worker-token` | 验证 Worker 的 transport token |
+| validation Worker | `aios-baseline-worker-token` | 仅用于连接本机 API |
+
+每个 unit 使用自己的 `LoadCredentialEncrypted=` 从稳定的 `/etc/credstore.encrypted/` 来源投影。两个服务可以获得同一个受治理 token 的独立投影，但任何服务都不读取另一服务的 `/run/credentials/<unit>/`。加密凭证名称与 `LoadCredentialEncrypted` 左侧名称必须一致，避免更名导致解密身份校验失败。
+
+JSON 中仅允许以 `${CREDENTIALS_DIRECTORY}/<name>` 引用自己的投影目录；不要写入 token、签名私钥或跨服务路径。Owner 公钥和 Runtime Contract 是受治理配置；Owner 私钥留在既有签发边界，不交给 API 或 Worker。凭证缺失时服务启动或操作准入必须失败，不能临时新建信任根或借用其他服务的运行目录。
+
+本包不提供生成生产信任根的脚本。测试在临时目录生成测试专用密钥；它们不能用于真实部署。实际安装前还要确认当前主机 systemd 支持这些加固项和 encrypted credential，并对已渲染 unit 运行 `systemd-analyze verify`。本地模板静态检查不能代替实际服务重启、token 轮换及读取权限验收。
+
+`service-status` 使用固定 `/usr/bin/systemctl show` 参数和可信 unit 映射，只读取注册组件状态。若目标主机限制状态读取，应对该命名 operation 配置最小读取权限；不要改成以 root 运行 API，也不要开放任意命令或 SSH。

+# ADR: R2 evidence digests reuse TaskPlane canonical JSON
+
+Status: ACCEPTED FOR R2 REVIEW CANDIDATE
+Date: 2026-09-14
+
+## Context
+
+R1 introduced local sorted/separator JSON encoders in schedulability proof and
+Retry/Toil fingerprint code. Platform Baseline V4 §1.3/§4.4/§12 prohibits new
+parallel canonical encoders unless a scoped ADR proves the existing contract is
+not applicable.
+
+The candidate already carries the established TaskPlane contract:
+
+`app.task_plane.models.canonical_json(value)`
+
+which serializes UTF-8 JSON deterministically with sorted keys and compact
+separators.
+
+## Decision
+
+R2 reuses `task_plane.models.canonical_json` for:
+
+1. schedulability observation/proof digests;
+2. Retry/Toil operation fingerprint payloads.
+
+Retry/Toil adds a domain schema wrapper
+`aios.retry-toil-fingerprint.v1` before hashing so the digest domain is
+separated without inventing a new byte encoder.
+
+No generic canonical platform, second encoder, or new write authority is added.
+
+## Bytes and algorithm
+
+- canonical text producer: `task_plane.models.canonical_json`
+- bytes: UTF-8 encoding of that exact text
+- digest: SHA-256 hex
+- schedulability schema: `aios.schedulability-proof.v2`
+- retry fingerprint schema: `aios.retry-toil-fingerprint.v1`
+
+## Migration / compatibility
+
+These R2 modules are not yet live authorities. Their R1 digests are review
+candidate evidence only and do not require backwards-compatible production
+decoding. Any future persisted proof/fingerprint consumer must bind schema
+version explicitly.
+
+## Guard
+
+R2 tests reject a reintroduction of local `json.dumps(sort_keys=True,
+separators=...)` encoders in the two modules.

+# AIOS Unified Platform Convergence — Architecture Change V2
+
+Status: R2 REVIEW CANDIDATE
+Date: 2026-09-14
+Authority base for rebind: `beabd053961047f170e87e1110f2636dbd50f5fb`
+
+## 1. Purpose
+
+R2 preserves the R1 architectural direction but corrects the eight review
+findings F01–F08. It does not authorize deployment.
+
+The program still has four tracks:
+
+1. existing Identity / Lineage S3;
+2. ANNEX-2.3 R2 Auto-Claim / Execution Integrity;
+3. Platform Generation G0 (WP0a–e/WP1/WP2 only);
+4. governed merge, staging, release and root/program acceptance.
+
+Existing Identity/Lineage mission/root/children remain authoritative and are
+not recreated or redefined by this program.
+
+## 2. Authority split
+
+- Git authority main: `beabd053961047f170e87e1110f2636dbd50f5fb`
+- release-control runtime: `3c320aeb89d9ba8f0ed516abeb57252682b18983`
+- production V2R2C2: `4642b74af62c89a505ae49241e805a5a88ca897f`
+
+A review candidate is not a governed commit. All target preimages must be
+refreshed from live Git authority before submission.
+
+## 3. R2 safety corrections
+
+### 3.1 Caller evidence is fail-closed
+
+`caller_scan v2` separates:
+
+- static source caller evidence;
+- active runtime caller evidence;
+- test-only evidence;
+- opaque/dynamic uncertainty;
+- complete negative evidence.
+
+Static source imports alone do not prove runtime LIVE.
+
+`PROVEN_ORPHAN` requires all of:
+- zero production static caller;
+- zero active systemd/API/scheduler/runtime-loaded caller;
+- relevant runtime host set non-empty and completely scanned;
+- loaded bytes negative proof;
+- systemd/API/scheduler scan coverage;
+- complete observation window;
+- no probe failures/opaque dynamic references;
+- rollback reference;
+- independent acceptance `GO`.
+
+Incomplete negative evidence returns `LIKELY_ORPHAN`; probe failure, opaque
+dynamic import, or unresolved production source caller returns `UNKNOWN`.
+UNKNOWN can never drive Sunset.
+
+### 3.2 Schedulability proof is diagnostic, final claim is authoritative
+
+R2 checks task lifecycle state and treats explicit `max_concurrency=0` as zero.
+Invalid capacity values are structured blockers.
+
+The proof remains non-bearer. Claim has three stages:
+
+1. preflight observation;
+2. claim-time read-only recheck;
+3. existing TaskPlane authority performs `claim_atomically` at the
+   linearization point.
+
+The atomic adapter contract must revalidate task revision/generation/status,
+worker generation/identity/health/capacity, authorization ref/revision,
+scope, dependencies, freeze and conflicting lease inside the same
+authoritative transaction/fenced operation that creates the claim.
+
+The returned receipt must include claim id, lease id, fencing generation and
+receipt revision.
+
+R2 reference tests verify the adapter contract only. They do **not** prove a
+production adapter is atomic; real staging A18–A23 remain mandatory.
+
+### 3.3 Retry Governor is whitelist-only
+
+- UNKNOWN/indeterminate → RECONCILE;
+- governance/dependency boundary → BLOCK;
+- proven success → SUPPRESS/REUSE;
+- unrecognized state → BLOCK;
+- only explicitly executable states may return EXECUTE.
+
+A prior success for the same operation conflicting with a later NOT_APPLIED
+observation must reconcile rather than re-execute.
+
+### 3.4 Canonical bytes are reused
+
+Schedulability and Retry/Toil reuse
+`app.task_plane.models.canonical_json`; no second JSON canonical encoder is
+introduced. See `ADR_CANONICAL_EVIDENCE_DIGEST_V1.md`.
+
+### 3.5 Platform G0 discovery is not G0 acceptance
+
+WP0a–d and WP1 now expose completeness/missing evidence. Lexical/static
+discovery cannot by itself satisfy Generation-G0 Exit.
+
+See `G0_EVIDENCE_COVERAGE_V2.md`.
+
+## 4. Non-circular review/deploy gates
+
+R1's production gate was circular because existing root C06 and Program
+production evidence could be required before production itself.
+
+R2 replaces it with:
+
+```text
+REVIEW_READY
+  ↓
+STAGING_ACTIVATION_READY
+  ↓
+STAGING_ACCEPTED
+  ↓
+PRODUCTION_ELIGIBLE
+  ↓
+PRODUCTION_ACCEPTED
+  ↓
+PROGRAM_COMPLETE
+```
+
+### REVIEW_READY
+
+Requires:
+- live authority rebind + exact preimages;
+- ChangeEnvelope complete;
+- complete affected repository regression;
+- independent review GO.
+
+### STAGING_ACTIVATION_READY
+
+Requires:
+- governed commit + authority readback;
+- bounded staging activation scope;
+- rollback/recovery plan ready;
+- pre-activation lab/contract evidence.
+
+It does **not** require evidence that only real staging activation can produce.
+
+### STAGING_ACCEPTED
+
+Requires actual staging:
+- TaskPlane adapter/claim/lease/fencing;
+- root action executor;
+- ANNEX A01–A23;
+- restart/response-loss/sibling concurrency/recovery evidence.
+
+### PRODUCTION_ELIGIBLE
+
+Requires:
+- STAGING_ACCEPTED;
+- existing release authorization valid;
+- production rollback ready;
+- freeze/NO-GO clear.
+
+### PRODUCTION_ACCEPTED
+
+Requires actual deployment:
+- production deployment/runtime readback;
+- authenticated business E2E;
+- external projection readback.
+
+### PROGRAM_COMPLETE
+
+Only after production acceptance:
+- existing Identity/Lineage original C01–C06 all accepted;
+- Program final acceptance all satisfied;
+- final root review proves no remaining acceptance gaps.
+
+The existing root acceptance contract is unchanged. Its full completion is
+consumed only by the final program-complete gate.
+
+## 5. State authority rules
+
+No new business authority is added.
+
+- caller_scan: read-only evidence producer;
+- WP0 inventories: read-only discovery;
+- Environment Profile: read-only host profile;
+- Retry Governor: decision/audit only;
+- SchedulabilityProof: short-lived diagnostic evidence;
+- SystemTruth: read-only derived view;
+- TaskPlane / existing claim transaction: authoritative task/claim/lease state;
+- existing mission/continuation path: root-action executor;
+- existing release Saga: release authority.
+
+No new Task DB, scheduler, mission store, release controller or authorization
+authority is introduced in R2.
+
+## 6. Migration
+
+- Existing mission/root/children: preserve IDs and acceptance.
+- Legacy durable task/job: attach metadata only; do not replace identity.
+- Schedulability proof: persist only through existing evidence/journal if
+  persistence is required.
+- No direct SQLite mutation outside existing TaskPlane repository.
+- G0 outputs remain shadow/read-only.
+
+## 7. Deployment status
+
+R2 code may proceed to live-authority rebase and repository-native review after
+its focused regressions pass.
+
+Deployment remains NO-GO until:
+- live preimages are refreshed;
+- full repository regressions pass;
+- atomic TaskPlane adapter is implemented and verified;
+- ANNEX A18–A23 pass;
+- real root-action executor consumes PENDING intents exactly once;
+- independent staging review is GO.
+
+## 8. Rollback
+
+Review candidate: discard candidate.
+
+Governed but undeployed commit: use existing successor/revert path; no shared
+branch reset/force push.
+
+Staging: disable feature/policy binding and preserve evidence.
+
+Production: existing release Saga rollback only.
+
+## 9. Deferred platform work
+
+WP3–WP10 remain dependency-gated backlog from Platform Baseline V4. R2 does not
+claim their acceptance and does not pre-build them.

+# G0 Evidence Coverage V2
+
+R2 corrects the R1 wording: WP0a–d and WP1 outputs are **discovery evidence**,
+not complete Generation-G0 acceptance by themselves.
+
+| WP | R2 output | What it proves | Still required for G0 Exit |
+|---|---|---|---|
+| WP0a | PARTIAL_DISCOVERY | authority/runtime/production OID relation | VERSION/current/baseline/README/versions/release metadata reader-writer-caller/live mapping |
+| WP0b | PARTIAL_DISCOVERY | lexical Git-writer candidates | writer→auth→repo→ref→CAS→receipt→caller graph and live classification |
+| WP0c | PARTIAL_DISCOVERY | authorization references by term/subdomain hint | owner/broker, TaskPrincipal, ClaimLease/TaskLease, WriterLease, release/recovery, signer chain + revocation/live caller |
+| WP0d | PARTIAL_DISCOVERY | function-level canonical/digest candidates | producer/consumer, input schema, bytes rule, algorithm and duplicate semantic groups |
+| WP0e | caller_scan v2 | fail-closed source/runtime caller evidence | five historical known-case acceptance + complete runtime evidence for any PROVEN_ORPHAN |
+| WP1 | capability discovery / requirements evaluated | actual local capability probes | declared host requirements for each key execution host, missing requirements resolved |
+| WP2 | conservative decision layer | retry/suppress/reconcile/block decision | audit baseline on real operations; no scheduler authority |
+
+`g0_exit_eligible=false` in WP0a–d output is intentional. The G0 gate is a
+separate acceptance aggregation step and must reference the missing evidence
+listed above.
+
+WP3–WP10 remain dependency-gated backlog exactly as Platform Baseline V4
+defines; R2 does not silently redefine the long-term platform goal to U01–U09.
