[NIU-123370]

Goal And Delivered Outcome

• Outcome basis / optional anchor: the nightly Full Public Smokes repository-hygiene-smoke.py failure with release timeline is missing version entries: v2.2.0.
• Goal/source and gap: v2.2.0 is tagged and the public stable ref points at the same commit, but the maintained release timeline stopped at v2.1.1. Before: the smoke rejects the timeline because the tag is absent from the document. After: the timeline records the release and the smoke passes.
• Observable before → after, with the validation row that proves it: with a local v2.2.0 tag (the hosted checkout carries it), python3 examples/repository-hygiene-smoke.py fails on base and prints repository-hygiene-smoke ok on this head.
• Issue/task and intended base: no issue; self-contained documentation 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/repository-hygiene-smoke.py at 1b636dee16, validate_release_timeline() at lines 346-360; the timeline admission rule at docs/product/release-readiness.md:988.
• Criteria:

Criterion (spec clause)	Disposition	Symbol / path	Test or command
Every version tag after the first public release appears in the timeline	implemented	docs/product/release-readiness.md	python3 examples/repository-hygiene-smoke.py
The entry names the tag, the commit, the public release and the versioned note	implemented	same	same
The timeline keeps its maintainer admission rule	implemented	line 988	same

• Self-check before submission: verified the annotated tag dereferences to 2c3524857e8a3dd553335b79444333786f492c43, the public stable ref points at that commit, the GitHub release is published on 2026-11-01, and the versioned note exists at the tag. The entry states only those facts and defers artifact/native-host claims to the release note; it does not add a new qualification claim.

Scope And Continuation

• Completed scope and remaining work: complete within this scope; the release history and product behavior are unchanged.
• Slice boundary / successor: N/A — the timeline entry is the whole exit.

Validation

• Tested revision: 7917bac82456501b8d8a5359ddc79bd121f72c64
• Run state: finished
• Input classes: synthetic

Check kind	Result	Public-safe evidence / limitation
integration	passed	With a local v2.2.0 tag, python3 examples/repository-hygiene-smoke.py → repository-hygiene-smoke ok. The hosted nightly checkout carries the same tag.
regression_parity	passed	The same command on base 1b636dee16 raises release timeline is missing version entries: v2.2.0.
static	passed	git diff --check; the hygiene smoke also runs the public/private boundary scan over the changed document.
unit	not_run	Documentation-only; no unit test covers the timeline prose.

• Coverage and gaps: documentation-only. The nightly workflow is intentionally not a PR-required check, so this PR does not attach a hosted CI run. The local tag was created only to exercise the smoke and was deleted afterwards; no tag is pushed by this PR.

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 the local premerge check passes, or no paired RFC changed (no RFC changed here).
• 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

阅读发布历史、准备升级的维护者和用户。

之前 v2.2.0 已公开发布，但维护的时间线停在 v2.1.1，仓库检查因缺少该版本失败；补记后读者能从同一时间线找到准确提交和版本化升级说明。

同一 hygiene smoke 在不可变基线报缺少 v2.2.0，在该 head 通过；新增十行之外的文档字节完全相同，原发布准入规则保留。

这里只补历史记录，不发布新版本、不移动 stable、不升级安装，也不扩大已发布版本的资格声明。

改动思路 / Approach

最有力的反对理由是发布说明已经存在，再写一份会制造两处维护责任。但这里保留现有时间线，只用一条记录指向正式 Release 和版本化说明，没有复制平台安装、迁移或能力启用步骤。不修改检查器、不删除 tag、也不放宽维护规则，是更小且完整的修复。

Git tag、公开发布页和已发布资格记录拥有各自的事实；时间线负责发现和导航，不能替它们授予发布或安装资格。当前完整边界是一次历史记录补全。已核对正式 Release 的源提交、日期与 stable，及版本化说明中的 canonical authority、context delivery 默认和更新读回边界。相关产品旅程记忆在这里用于检查读者能否找到既有升级说明；它不能变成重做产品功能或继承旧评审结论的要求。

具体改动 / Changes

完整 head 7917bac82456501b8d8a5359ddc79bd121f72c64 仅 docs/product/release-readiness.md +10/-0，生产、测试、生成物及协议均未修改。接受依据为 docs/product/release-readiness.md，spec_revision 1b636dee161f5ec0039b2c0121ef7ff7060dcb72 的既有时间线准入条款，而不是本 PR 新写的说明。

关键内容讲解

• 新增时间线条目 记录 v2.2.0、完整提交 2c3524857e8a3dd553335b79444333786f492c43、正式 Release 日期及版本化说明。TL-tag-release 与 TL-stable：公开非 Draft Release 的发布时间为 2026-11-01，tag 解引用和当前 stable 都是同一提交。
• TL-note-update：从 tag 对应的不可变提交读取版本化说明，确认 canonical authority 迁移、支持宿主的 context delivery 默认及显式关闭、按原 owner 更新和独立读回等被引用内容；条目没有声称所有宿主已采用。
• TL-canary-boundary：正式发布的资格记录 的 product commit/tree 与 tag 一致，下载字节摘要也匹配 GitHub asset digest。它明确是 bounded risk-based qualification，保留全量测试、模型矩阵及 PostgreSQL 等未重新验收项。这里核验来源一致性，没有冒充重新执行其历史测试。
• TL-admission：原有“tag、release note、stable、update path 和 focused canary 一致后才加入”的准入段落 及其后全部内容逐字保留。既有 hygiene 检查器和文档检查器也没有变化。

对主干的风险 / Risks

未发现阻塞问题。最强反例是填一个版本名字便让 hygiene 通过，却写错日期、提交或升级边界；现有检查确实只查 tag 是否出现在时间线，不能证明这些内容。对此独立比较实际公开 tag/stable/Release、不可变版本说明与已发布资格记录，未依赖作者的自检数字。资格记录仍是历史来源证据，不能证明本机安装成功或持续工作收益。

PASS：当前 head 的完整 repository-hygiene-smoke、release-readiness-doc-smoke、diff hygiene，以及 quick premerge 的四个直接检查、三个 catalog canary 和一个公开边界检查。基线的 hygiene 失败被完整保留，唯一缺失版本是 v2.2.0。没有查询、轮询或等待 CI，也没有为此文档变化执行无关的大套测试。新条目以外全文件字节相等，使权限、安装和发布门没有被静默改写；恢复只需撤销该条目。

我的整体评价 / Verdict

goal_achieved 仅针对维护时间线的遗漏。long_horizon 为 preserved，运行、调度和后续工作规则没有变化；user_experience 为 improved，读者从现有历史入口就能找到真实发布与升级限制，无需新增配置、信息重填或确认轮次。检查对象为 docs/product/release-readiness.md 的既有末段时间线文字，没有页面组件、布局或产品交互改动；视觉检查不适用。未执行原生安装、完整测试或模型矩阵，也未重新认证历史发布资格。

十行记录复用现有 owner 和版本化说明，属于必要且可独立回退的维护增量；没有兼容层或语义词表变化，不需要新 helper 或人为后续任务。当前 scoped CQR 有效。批准针对准确 head 的文档修复，发布、安装和合并授权仍各自独立。

English verdict: APPROVE — 7917bac restores the missing v2.2.0 timeline entry. Public source identities agree, both focused smokes and quick premerge pass, and existing release limits remain unchanged.
