[github-actions]

Automated by the blog pipeline (scripts/blog-discussions.mjs).

Records newly created Discussion thread numbers into website/articles.json.
Repo policy: the pipeline never pushes master directly; numbers land here
as exactly one PR for a human merge (same posture as release-manual.yml).

• One file changed: website/articles.json.
• Safe to squash-merge. If the pipeline runs again before this merges,
  the same branch/PR is refreshed in place.
• Until merged, the discussion button stays hidden — nothing breaks.

Conflict resolved. Rebased bili-blog-pipeline-manifest onto current master and force-pushed (lease-pinned to the pre-rebase sha; remote head was unchanged, so no concurrent work was clobbered). New head: 77afef1897.

What happened: the branch was cut from Nov-1 master (db73897a45) and master has since moved ~916 commits ahead — including PR #6150, which removed the compress-at-fold-point article and its website/articles.json entry. The pipeline commits add discussion fields to entries in that same file, so both sides rewrote the same region → dirty.

Resolution followed union-of-intent, minimal and faithful:

• Commit 1 (original thread numbers): kept discussion fields for the two surviving articles; did not resurrect the fold-point entry that master deliberately deleted.
• Commit 2 (pipeline refresh run): kept the refreshed numbers — meet-bili→6162, frequent-compression→6163 — superseding the intermediate values.
• Final branch diff vs master is exactly two added lines in website/articles.json; no other file touched, JSON validated parseable.

Live verification this run (mirror cache, fetched 03:34Z+): mergeable_state flipped dirty → blocked on the new sha — i.e. mergeable again, held only by still-running required checks. CI summary at last poll: total 30 / failed 0 / pending 12 (test-matrix shards in progress; 11 env-gated e2e lanes skipped, normal for a website-only diff; static-gates ubuntu already green). If any shard goes red I'll pick it up in the next lane attempt (this was attempt 1/3). Merge remains human-only.

七问

1. 是什么问题:博客流水线的 manifest PR([PR] [bili-blog-pipeline] record discussion threads (meet-bili→#5550, frequent-compression→#5551, compress-at-fold-point→#5552) #5553)与 master 冲突(dirty),无法合并。
2. 什么原因导致的:分支基于 11-01 的旧 master(db73897);此后 master 合入 [PR] remove: the experimental compressAtFoldPoint feature — fold-point relocation (v1 #5471 + unreleased v2 #5949), #6132 #6150 删除了 compress-at-fold-point 文章及其 articles.json 条目,而 PR 两个提交在同一文件同一区域添加 discussion 字段——双方改动重叠产生文本冲突。
3. 影响范围与严重程度:仅影响博客页 discussion 按钮的记录数据(合并前按钮保持隐藏,无功能破坏);严重度为合并阻塞级,无用户可见缺陷。
4. 怎么修复的:把两个流水线提交 rebase 到当前 master(33104b1),按意图并集解冲突——保留两篇存续文章的 discussion 字段、采纳第二个提交的刷新编号(6162/6163)、不复活 master 已删的 fold-point 条目;最终对 master 的 diff 仅两行数据。
5. 是否有回归问题:无。纯数据追加,未触碰任何代码路径;核对过既有行为——master 原有两条文章条目逐字保留、顺序与格式不变、JSON 通过解析校验。
6. 是否破坏缓存:不涉及——未触及任何缓存/重试/游标逻辑。
7. 是否改了设计方向或引入新配置:均无。

收工判定:冲突已解除并实证(dirty→blocked),CI 在途 0 失败,等待人工合并。

APPROVE — merge stays human-only (§7.4). Scope: bot write-back from scripts/blog-discussions.mjs; one data file; no code.

Independent verification (not taken from PR text)

1. Diff vs master at head 49f15633eb: only website/articles.json changed — the two pre-existing entries each gain one discussion field (meet-bili→5550, frequent-compression→5551); entries otherwise byte-identical, order/format unchanged; JSON parses; both referenced post files exist.
2. Consumer contract matches exactly: src/web/blogfeed.ts:498 accepts only integer>0 (else dropped → button hidden); src/web/client.ts:1057-1058 renders …/discussions/<num>. No test pins real manifest numbers (suites use synthetic fixtures), so no test coupling either way.
3. Thread liveness via GraphQL (read-only): #5550 “Meet billion-context · 认识 billion-context” and #5551 “What to do when billion-context compresses frequently? · billion-context频繁压缩该怎么办?” are ALIVE; titles equal the articles’ frontmatter title/title_zh joined per threadTitle().

Finding fixed on the spot (the only code change of this review)
The head I was dispatched against (77afef189) recorded #6162/#6163 — duplicate threads created by the 2026-11-11 refresh run, deleted shortly after creation (verified live at 12:55Z, NOT_FOUND by 13:11Z). Merging as-is would ship panel buttons pointing at dead threads (404), and per the pipeline’s own verifyRecorded semantics (“a vanished thread is NOT resurrected automatically”) it would never self-heal. Fixed by commit 49f15633eb, which points the manifest at the surviving original threads from the 2026-11-02 run.
已顺手修：manifest 指向的 #6162/#6163 是创建后数小时内即被删除的重复线程（照原样合并会让面板按钮指向 404，且按流水线设计不会自愈）——改指存续原线程 #5550/#5551 + commit 49f1563

Root cause of the duplicates (out of scope for this data PR — escalated separately as the 🔶 需要决策 comment below): idempotency layer 2 scans GraphQL bodyText for the invisible marker <!-- bili-blog:<slug> -->, but bodyText strips HTML comments (proven on #5550, written by this same script whose marker code has existed since its first commit 03473b1). While this PR sits unmerged, every qualifying blog push re-creates another duplicate pair; merging promptly stops that machine for the current entries (layer 1 then covers them).

Regression sweep: pure additive data on a defensively-parsed manifest; no code path, cache/retry/cursor logic, config surface, or kernel/ touched. PR title still lists the Nov-02 numbers incl. the fold-point thread (stale after the rebase onto #6150) — title is system-pipeline-owned per AGENTS.md, left untouched.

CI: new-head run in progress at posting (guards green, 0 failures so far); the identical-shape previous head went 30/30 green.

八问

1. 是什么问题:博客流水线的 manifest PR——把两篇文章的 GitHub Discussion 线程号记入 articles.json,面板文章页才能显示讨论入口(合并前按钮保持隐藏)。
2. 什么原因导致的:我接到的 head 记录了 11-11 流水线重跑创建的重复线程 #6162/#6163——幂等第二层(marker 扫描)因 GraphQL bodyText 剥离 HTML 注释而结构性失效,扫不到已存在的 #5550/#5551 便重复建帖;重复帖随后被人工删除。
3. 影响范围与严重程度:修复前=合并后面板按钮指向 404(用户可见缺陷,且按流水线设计不自愈);修复后=零缺陷,纯数据追加。
4. 怎么修复的:manifest 两个数字改指存续原线程 #5550/#5551(GraphQL 独立验证存活、标题与文章 frontmatter 逐字一致);流水线脚本缺陷不塞进本数据 PR,单独走 🔶 升级。
5. 是否有回归问题:无回归——diff 仅给两条既有条目各加一个字段,条目本体/顺序/格式逐字不变,JSON 过解析校验,消费端谓词(integer>0)匹配,零代码路径触碰。
6. 是否破坏缓存:不涉及。
7. 是否改了设计方向:无。
8. 是否引入新配置:无。

判定:可合(PR body 声明 squash-merge safe;合并权按 §7.4 留人工)。建议尽快合并——未合并期间每次命中博客面的 push 都会再产生一对重复讨论帖(见下方 🔶 评论)。

[ranxianglei]

🔶 需要决策: blog pipeline idempotency layer 2 is structurally dead — duplicate discussion threads re-create on every qualifying push while the manifest PR is unmerged

PR: #5553 (this thread). Gated diff: none inside this PR — the defect lives in scripts/blog-discussions.mjs, which this data write-back does not touch; escalating because fixing it changes a safety-mechanism behavior and needs an owner call on approach.

Evidence chain (all verified independently during review):

1. threadBody() appends the invisible marker <!-- bili-blog:<slug> --> to every created thread (scripts/blog-discussions.mjs:217); the crash-recovery scan findMarkerInRecentDiscussions() (scripts/blog-discussions.mjs:269-292) looks for that marker inside GraphQL bodyText.
2. GraphQL bodyText strips HTML comments. Proof: discussion Meet billion-context · 认识 billion-context #5550 was created by this exact script (marker code present since its first commit 03473b1, 2026-11-01), yet its bodyText contains no “bili-blog:” substring at all (markdown emphasis/blockquote markers are stripped too — bodyText is rendered plain text).
3. Production consequence already observed: the 2026-11-11 02:24Z refresh run (triggered by [PR] remove: the experimental compressAtFoldPoint feature — fold-point relocation (v1 #5471 + unreleased v2 #5949), #6132 #6150 touching articles.json) failed to find Meet billion-context · 认识 billion-context #5550/What to do when billion-context compresses frequently? · billion-context频繁压缩该怎么办? #5551 and created duplicates #6162/#6163; those were deleted manually within hours. This review’s fix commit 49f1563 points the manifest at the surviving originals.
4. Residual risk while unmerged: layer 1 (verifyRecorded) only protects numbers already recorded ON MASTER — master still has none → every further push touching website/blog/posts/** or website/articles.json creates yet another duplicate pair. Merging this PR is NOT gated by this decision, and merging mitigates it (layer 1 then covers the current entries).

Options:

• A (recommended): scan REST GET /repos/{owner}/{repo}/discussions pages instead (raw body, same api.github.com host the script already uses, existing ghJson helper). Keeps the invisible-marker format, fully backward-compatible with existing threads’ markers, single-function rewrite (~30 lines), zero new deps.
• B: make the marker visible footer text in new threads — changes user-visible thread content format; old threads’ invisible markers still unmatchable → strictly worse backward compat than A.
• C: accept the risk (rely on layer 1 + prompt merges) — duplication window persists for any period where a thread exists but its number is not yet on master.

Recommendation: A. Deliberately not bundled into this PR (data write-back vs pipeline script; bot-refreshed branch). Requesting owner decision: approve A / pick B / accept C.

查重：不重复 — single pipeline write-back PR; verified via pulls?head=ranxianglei:bili-blog-pipeline-manifest that #5553 is the only open PR on this branch. No other open/closed issue or PR covers the same scope.

标签：needs-decision（流水线幂等缺陷需 owner 拍板修法，见下）· scope/ui（博客面板数据面）· p3（修复后本 PR 零缺陷；残留问题仅产生可清理的重复讨论帖，无数据损坏）。

已顺手修：manifest 指向的 #6162/#6163 是创建后数小时内即被删除的重复线程（照原样合并会让面板按钮指向 404，且按流水线 verifyRecorded 设计不会自愈）——改指存续原线程 #5550/#5551 + commit 49f1563（已推分支，diff vs master 仍仅两行数据）。

What I verified independently (not from the PR text):

• Diff vs master at final head 49f15633eb: only website/articles.json, two pre-existing entries each gaining one discussion field, otherwise byte-identical; JSON parses; both referenced post files exist.
• Consumer contract: src/web/blogfeed.ts:498 accepts integer>0 else drops the field (button hidden); src/web/client.ts:1057-1058 renders …/discussions/<num>. No test pins real manifest numbers (synthetic fixtures only).
• Thread liveness via GraphQL read-only: Meet billion-context · 认识 billion-context #5550 and What to do when billion-context compresses frequently? · billion-context频繁压缩该怎么办? #5551 alive; titles match the articles' frontmatter title/title_zh exactly. The as-dispatched head's numbers (#6162/#6163) were deleted within hours of creation — confirmed live→NOT_FOUND across two probes.
• CI on the fixed head: 30 checks / 0 failed / 0 pending (mirror cache) — fully green, same shape as the previous head's 30/30.

🔶 需要决策 (escalated on-thread on GitHub: #5553 (comment), label applied here): the pipeline's idempotency layer 2 is structurally dead — it scans GraphQL bodyText for the invisible marker <!-- bili-blog:<slug> -->, but bodyText strips HTML comments (proven on #5550, written by the same script). Consequence: while this PR sits unmerged, every qualifying blog push re-creates duplicate discussion threads (today's deleted pair #6162/#6163 is the observed instance). Options A/B/C with recommendation A (switch scan to REST discussions list returning raw body) are in that comment; merging this PR is NOT gated by the decision and merging mitigates it. Script untouched in this review — out of scope for a data write-back.
