[NIU-123370]

Goal And Delivered Outcome

• Outcome basis / optional anchor: the nightly Full Public Smokes docs-governance-smoke.py failure introduced by RFC: joint target/yardstick selection with lightweight Stride decisions #8105.
• Goal/source and gap: target-yardstick-stride-decisions-v0 was merged without the bilingual semantic-mirror markers the governance check requires. Before: docs-governance-smoke.py exits 1 with AssertionError: target-yardstick-stride-decisions-v0.md, then with the zh-CN mirror. After: it prints docs-governance-smoke ok.
• Observable before → after, with the validation row that proves it: python3 examples/docs-governance-smoke.py fails on the missing semantic mirror / 语义镜像 markers; after this change it passes.
• Issue/task and intended base: no issue; self-contained maintenance repair. Intended base is loopx-project/loopx:main.

Author Declaration

• Written by: model_agent — Qoder AI assistant, at the contributor's direction; no human review has occurred.

Implemented against

• Specification and revision: examples/docs-governance-smoke.py at 1b636dee16, checks at lines 202-203; the merged RFC from RFC: joint target/yardstick selection with lightweight Stride decisions #8105.
• Criteria:

Criterion (spec clause)	Disposition	Symbol / path	Test or command
English RFC contains semantic mirror	implemented	docs/architecture/rfcs/target-yardstick-stride-decisions-v0.md:11	python3 examples/docs-governance-smoke.py
Chinese RFC contains 语义镜像	implemented	docs/architecture/rfcs/target-yardstick-stride-decisions-v0.zh-CN.md:11	same
Reciprocal language links remain intact	implemented	both header lines	python3 scripts/check_rfc_bilingual.py --base upstream/main --head HEAD

• Self-check before submission: read both RFC headers and the governance check, changed only the two header labels, ran the governance smoke and the bilingual premerge check. No runtime or semantic RFC content changed.

Scope And Continuation

• Completed scope and remaining work: complete within this scope; no runtime behavior changes.
• Slice boundary / successor: N/A — the two header markers are the whole exit.

Validation

• Tested revision: 9d7d70a1aa08f0892089eb9c6676819b9c76573c
• Run state: finished
• Input classes: synthetic

Check kind	Result	Public-safe evidence / limitation
integration	passed	python3 examples/docs-governance-smoke.py → docs-governance-smoke ok.
regression_parity	passed	The same command fails on base 1b636dee16 with the missing-marker assertion and passes on this head.
static	passed	git diff --check; python3 scripts/check_rfc_bilingual.py --base upstream/main --head HEAD → RFC bilingual diff check passed.
unit	not_run	Docs-only; no unit test covers RFC header text.

• Coverage and gaps: documentation-only; no runtime surface changed. The nightly workflow is intentionally not a PR-required check, so no hosted CI run is attached to this diff.

Frontend / Visual Evidence

• UI impact: none
• Before: N/A

Type of Change

• Documentation update

LoopX Area

Technical Direction

• Direction / acceptance reference, when applicable: N/A

Shared-authority RFC fixture impact

• Production-scale fixture schema: N/A
• Semantic dimensions changed, or reviewed no-impact rationale: N/A
• Provider conformance arms run: N/A
• Read-only legacy/file/PostgreSQL three-arm rehearsal (required for promotion, runtime-routing, or compatibility-projection changes): N/A

Boundary Checklist

• Neither the diff nor this PR body/comments/attachments disclose private state, credentials, raw traces or verifier output, internal links, or local machine paths (including .loopx/, .codex/goals/, and live ACTIVE_GOAL_STATE.md).
• I did not duplicate maintainer-owned benchmark work unless a maintainer split out a public issue for it.
• I kept the change scoped to the linked issue/task.
• Existing English/Chinese RFC pairs both have a diff, and python3 scripts/check_rfc_bilingual.py --base upstream/main --head HEAD passes.
• I completed the visual evidence section for UI changes, or marked UI impact none.
• Every commit includes a DCO Signed-off-by trailer (git commit -s).

动机 / Motivation

维护者运行完整文档治理检查时，会在本来已经成对存在的 RFC 上失败。

主线在英文镜像标记断言处退出；当前提交补齐中英文标记后，原完整检查通过，互链仍指向原文件。

该改动恢复了既有文档治理入口，并保留缺标记、坏互链和缺镜像的拒绝行为。

本 PR 只修复两处文档标签，不交付 Stride/Yardstick 实现、默认变更、实验资格或长期收益证明。

改动思路 / Approach

已有校验器要求英文文件明确包含 semantic mirror、中文文件包含“语义镜像”，并检查镜像文件和双向链接。当前修复只调整原互链标签，继续由同一个文档治理函数读取同一对文件。不改会保留真实失败；删除断言或给这份 RFC 加例外会削弱公共规则。两处直接标注是完整且更窄的修复，不需要另加 helper、测试框架或兼容分支。

实际执行路径是原完整文档检查进入镜像校验，再继续原有 ledger、状态索引等检查。正例使用真实 source checkout；反例只隔离 DOCS 根目录，调用未修改的实际函数，未模拟“检查通过”这个后置条件。

具体改动 / Changes

审查绑定完整 head 9d7d70a1aa08f0892089eb9c6676819b9c76573c，base 为 1b636dee161f5ec0039b2c0121ef7ff7060dcb72。完整差异是两份文档各 +1/-1，提交含 DCO trailer。依据变更前的 RFC 模板，spec_ref=docs/architecture/rfcs/TEMPLATE.md，spec_revision=1b636dee161f5ec0039b2c0121ef7ff7060dcb72；以下标识仅映射原文要求。

规格映射	当前 head 的处理
MIRROR-PAIR	implemented：原英文与同名中文文件成对保留，补上既有镜像标注；完整治理检查和缺镜像反例验证。
MIRROR-LINKS	implemented：两端仍是原相对链接，独立解析确认落到原文件；坏互链被原 owner 拒绝。
MIRROR-NORMATIVE	implemented：完整文件逐字节比较，仅两处标签替换；其余正文、规范修订、生命周期和实现基线不变。双语 diff 与 RFC 状态索引检查通过。

关键内容讲解

英文第 11 行 将 Language mirror 明确为 Semantic mirror；中文第 11 行 写明“语义镜像（语言镜像）”。两处链接目标保持原值。消费它们的 check_rfc_language_mirrors 及 allowlist 没有修改。这些是文档标注，不是新增状态、权限或执行协议。

对主干的风险 / Risks

没有发现阻塞问题。最强反例是只补英文标记，或者用标记掩盖互链/正文错误：前者仍会在中文断言处失败。独立探针分别去掉英文标记、中文标记、破坏互链、删除中文镜像，四项均被实际 owner 拒绝；同时确认原文件未被探针改动。完整 blob 对照补充了简单字符串检查不能证明的正文保真边界。

验证	结果
完整 docs-governance-smoke	base FAIL：缺英文标记；head PASS，完整执行结束。
镜像、互链和正文保真	PASS：真实正例及四个拒绝反例，原相对链接和非标签字节保留。
双语差异、RFC 状态索引、diff hygiene	PASS，均在上述 head 与实际 base 运行。
CQR / quick premerge / 公开边界	PASS；exact-scope CQR 有效，quick 整体通过：四项直接检查、语义词汇、候选来源及公开边界通过，另保留一项旧失败 advisory；公开扫描 0 errors / 0 warnings。
既有 maintainability ratchet	FAIL 保留为 advisory：base/head 完整报告只去除各自 repository_root 后相同。

最后一项的实际同源失败为 _admitted_interaction_next_cli_actions 的 62 decision points，原阈值 60；相关代码、检查器和配置未变，未修改阈值或将失败改绿。首次 quick 因隔离工作树缺少 TypeScript 开发依赖失败；按既有 npm ci --ignore-scripts 准备后，同一 head 重跑通过，原失败保留。按 wait_for_ci=false 未查询或等待远端 CI，不声称托管 workflow 已通过。

我的整体评价 / Verdict

交付判断为 goal_achieved，仅结清这次有独立复现的文档治理修复。long_horizon=preserved：原研究、Stride、预算与后续验收义务不变；user_experience=preserved：原有双语导航继续可达，没有新增配置或确认轮次。改动限于两份 RFC 第 11 行的互链标签；没有产品页面、布局、展开或响应式行为变化。未验证托管 Markdown 页面的视觉呈现，也未重新认证整篇 RFC 的翻译或研究结论。

两处修改复用原 owner，代码量与实际缺口相称；没有需要顺带重构的运行时边界。批准限于这个未变 head，合并权限与 GitHub 就绪度另外核验，旧维护性债务继续保留。

English verdict: APPROVE — 9d7d70a repairs the reproduced documentation-governance failure while preserving the original links, RFC bytes and rejection checks. Hosted CI and the underlying RFC implementation are not qualified here.
