[PM decision] skills lane batch 9 — platform-readings.md third increment: raise the ceiling by the measured +39 (358 → 397); and the MCP write-pool quota sentence collision

[claude]

呈维护者裁决 —— skills 席(session session_019RfFHiRCSs3JXLK4cwcfox,os-steve),第 9 批,共 2 项。裁后一行回批即可(「1A 2C」/「1A, 但…」)。

1. platform-readings.md 第三增量:实测 +39 行(358 → 397),要不要按实测抬上限

一句话问题:上一批裁的 +34 只覆盖 intake 家族的八条读数;此后又攒下四组席位实打实踩过的平台读数,测量先行飞行已把它们按文件口吻写好、按门禁自己的 wrapLine 折行,合计 +39 行,上限行未动,PR 按设计在棘轮上红着等这一裁。

背景:.claude/skills/pm-dispatch/references/platform-readings.md 现为 358/358(余量 0,#15013 的 1A 于 PR #15190 落地)。PR #15265 40250c51,受管草稿)只加不删(+39/−0),四个成员各自的来源、落点与行数如下(dev 实写实折,本席在分离工作树复核:文件 397 行、check:skill-frame-sync / check:pm-skill-id-lint / check:nul-bytes 绿、merge-tree 干净):

成员	来源	落点	行数
署名页脚的写侧变异按通道 × 动作/输入定域,⛔ 不是一条定律(四次独立观察:MCP 包装器删块、裸 REST PATCH 追加裸页脚、MCP 重送带页脚正文两页脚存活 n=1、裸 REST POST 建 PR 追加 session-URL 页脚 +90)	#14133 裁后读数 + #15192 评论 5536878608 + #15246 + 本飞行实测	读数陷阱段	+12
MCP 侧限流是窗口读数不是 PR 信号:被挡住的翻转只等窗口,不据它重挂、不改判	#14133 裁后读数	API 配额段	+6
「本档的缺席不是读数」的成因:CDN 缓存、专对最新内容失效、cache-busting + no-cache 绕不掉	#13387	API 配额段	+5
Routine 传输三则:起的会话不带 GitHub 工具;自绑用新会话可恢复性换工具可得性 + 孤儿定时器复原规则(实测躺了 6 天);创建端无 sources / model	#13257(2026-09-04 按本会话工具契约复核,两处变化标为未实测)	断粮段	+16
		合计	+39

带 re-check 命令的前提:

• 上限与现状:git fetch origin pull/15265/head && git checkout FETCH_HEAD && node scripts/pm/check-skill-line-ratchet.mjs | grep platform-readings → is 397 lines; the ratchet ceiling is 358(唯一一条 ✗;120 字节行规则通过)。
• 去重已做过两次删减:限流成员从 +7 减到 +6(两桶分离已在「信封」条里),页脚成员从 +10 减到 +12 前的 +9(作者侧处方住 AGENTS.md,本条只定作用域)—— 文件里没有任何可删的旧句来付账([PM decision] skills lane batch 7 — raise the platform-readings.md line ceiling by the measured +34 so the intake family's eight readings can land #15013 已测)。
• 机械说明(落地补丁轮用):PR tooling(pm): price a destination's ordinary ruled raise apart from its move's #15266(check-skill-line-ratchet: an ordinary ruled raise on a destination that carries a live CROSS_FILE_MOVES declaration is priced as the move's raise — separate the two quantities instead of carrying was forward #15191,已复审待翻)把「移动的抬升」与「普通裁定抬升」分开记账 —— 这次抬升落成该声明的第二条 ruledRaises 记录(引用本裁决原文),⛔ 不再把 was 往前推;补丁轮排在 PR tooling(pm): price a destination's ordinary ruled raise apart from its move's #15266 落地之后。

方案与四轴分析:

• A. 按实测抬 +39 → 397,四个成员全部落地(推荐)
  • 实际业务需求:四组都是席位在真实操作那一刻要用的读数,其中三组是有席位被烧过才测出来的(把缺席当读数、把 MCP 拒绝当 PR 信号、把一次页脚观察当定律);页脚一行已经有四次独立观察跨三条通道。
  • 项目长远合理性:不落地的替代是同一文件的第五个增量卡,正是这个卡家族要终结的堆积;读数表是这些事实唯一的归宿,去重两次删减说明文件没在灌水。
  • 防 AI 写代码犯错:这一轴最强 —— 四组里三组写成 ⛔ 禁令,针对的都是已经发生过、已经错了的推断;Routine 行对「现在有工具了」的推断也带 ⛔。
  • 创业阶段不扩散需求:Routine 家族服务 PM 车道自己的定时器选型,不是客户面 —— 但它不是能力扩张,是对席位已在用的机制的实测约束,其孤儿复原规则是那半条让一个定时器躺了 6 天没人察觉的教训。
• B. 少抬、砍成员:去掉 Routine 家族(+16)→ +23,381
  • 实际业务需求:保住三组被烧出来的读数;Routine 三则回卡上等。
  • 项目长远合理性:Record the agent-created-Routine transport facts in references/platform-readings.md — fired sessions get no GitHub MCP tools, and self-binding trades new-session recoverability for tool availability #13257 从两个增量都漏到现在,再漏一次就是第四次呈报同一件事。
  • 防 AI 写代码犯错:丢的恰是带「⛔ 永不留孤儿」的那条规则。
  • 创业阶段不扩散需求:这是 B 成立的轴 —— 最严格的 scope 线;若维护者要守这条线,B 是自洽的小切法,上限 381。
• C. 拒绝抬升,四组留在各自卡上
  • 实际业务需求:读数继续散在四张卡里,下一席仍从卡而不是从参考文件读。
  • 项目长远合理性:与「参考文件是唯一归宿」的既有裁决相反;四张卡长期 pm:blocked。
  • 防 AI 写代码犯错:三条已验证的 ⛔ 不进操作文本,同类错误再犯的门开着。
  • 创业阶段不扩散需求:零行,最紧;代价是上面三条。

推荐意见:A。四轴里只有「创业阶段」一轴给 B 留了理由,且它针对的成员(Routine)本身不是能力扩张而是约束;其余三轴都指向 A。

2. 文件首条配额禁令 vs 「MCP 池按身份跨席共享」的读数:哪句站得住

一句话问题:新成员引用的裁后读数从限流报文里的 user ID 得出「MCP 池按身份跨席共享」;而文件首条配额句原文是「⛔ 不据限流报文里的 user ID 推「池子跨席共用、优化自己没用」,本席额度完全由本席做法决定」。两句正面冲突;dev 没改任何既有句,把冲突在新成员里标为「⛔ 未裁不写成事实」。

带 re-check 命令的前提:

• 实测在手的那半(同一分钟 MCP 拒绝、本席 REST /rate_limit 读回 15000/15000)不能判别:本席自己耗尽 MCP 池同样解释得通,且文件已记这半。
• 本席补一条自己的读数(不据 user ID):本班 MCP 调用总数约 15 次(只用于 draft 翻转与 auto-merge 挂载),却在 02:17Z / 04:37Z / 06:31Z / 07:14Z 四次撞到 API rate limit already exceeded;一个只由本席用量决定的每小时额度不该被 15 次调用打满 —— 这与「完全由本席做法决定」相悖,但它仍是旁证,不是判别测量。
• 判别测量便宜:两个席位在同一分钟各自以 MCP 身份读 /rate_limit(或对照 REST 的 rate.remaining),一次即可定案,不必造任何东西。旧卡 [Decision] The shared GitHub identity's GraphQL quota is being burned to 2× — MCP writes go through GraphQL, so seats are silently write-blocked while reads keep working #11742(pm:on-hold,共享身份 GraphQL 配额被烧到 2×)记的是同一池子的另一面。

方案与四轴分析:

• A. 既有句成立,新成员删掉「未裁」子句只留实测半句
  • 实际业务需求:席位继续按「优化自己的用法」行事 —— 若池子其实共享,这个建议对被挡的席位没用。
  • 项目长远合理性:一句写死的规则若与现实相反,越久越贵。
  • 防 AI 写代码犯错:禁止从 user ID 推断是对的纪律;问题只在结论半句。
  • 创业阶段不扩散需求:零改动。
• B. 读数成立(池按身份共享),把既有句收窄到 REST 通道
  • 实际业务需求:席位得到正确的等待策略(等窗口、错峰、别重试)。
  • 项目长远合理性:同一文件内一次受管编辑,顺手可做;但依据的是一次不能判别的观察 + 旁证。
  • 防 AI 写代码犯错:用一个观察改写一句逐字禁令,正是文件自己反对的做法。
  • 创业阶段不扩散需求:改一句,不扩面。
• C. 两句并存(PR 现状),先做判别测量再裁(推荐)
  • 实际业务需求:席位当下已能按新成员的操作规则走(等窗口、其余走 REST),不需要先定池子归属。
  • 项目长远合理性:一次便宜测量换一句能长期站住的话;[Decision] The shared GitHub identity's GraphQL quota is being burned to 2× — MCP writes go through GraphQL, so seats are silently write-blocked while reads keep working #11742 顺带一并了结。
  • 防 AI 写代码犯错:不凭单次观察改逐字规则,也不让一个未验证结论进操作文本 —— 两个方向都守住。
  • 创业阶段不扩散需求:不新增任何机制,只安排一次读数。

推荐意见:C,并请授权本席与另一席位在同一分钟做那次 /rate_limit 对照读(零成本),结果回到本卡后再按 A 或 B 一行裁掉。

落地方式

裁 1 后:PR #15266(#15191)落地 → #15192 补丁轮把上限行改成裁定值、引用本裁决原文、在 CROSS_FILE_MOVES 声明上加第二条 ruledRaises 记录;受管 ⇒ 草稿、双批准人、人工合并。裁 2 后:按 A/B 在同一补丁轮里改那一句(或 C:先测再裁)。

Maintainer ruling recorded — item 1: A (raise the ceiling by the measured +39, 358 → 397); item 2: C (both sentences stand; the discriminating measurement comes first). needs-user-decision → pm:queue in the same stroke.

Director seat, summon 14 (session_01LsEjuNMPitCHwEfYftZ1um, GitHub os-warren). Provenance: maintainer, live PM chat, 2026-09-04, decision batch #34, verbatim 「决裁批 #34 同意」 on the presented recommendation 1A · 2C · 3B. Premises re-verified by this seat before presenting: PR #15265's file is 397 lines against a ceiling of 358; two dedup passes already recorded; no removable old sentence in the file to pay for the increment (#15013).

Item 1 — A

1. platform-readings.md's ceiling moves to 397 and all four members of PR docs(pm-skill): write the third platform-readings increment and measure it at +36 against the 358 ceiling #15265 (platform-readings.md third increment: the two post-ruling channel facts (+11), #13387's CDN-cache cause, and #13257 — needs its own ceiling ruling before dispatch #15192) land: footer-mutation scoping by channel × action (+12), MCP rate-limit as a window reading not a PR signal (+6), the CDN cause behind "absence is not a reading" (+5), the three Routine transport rules including the orphan-timer recovery rule (+16).
2. ⛔ Not B: the member B drops is the one rule that already cost a six-day orphaned timer, and Record the agent-created-Routine transport facts in references/platform-readings.md — fired sessions get no GitHub MCP tools, and self-binding trades new-session recoverability for tool availability #13257 would miss its third increment.
3. ⛔ Not C: the reference file is the readings' only home (standing ruling); leaving four cards pm:blocked is the accretion this card family exists to end.

Execution (skills seat): PR #15266 (#15191) lands first → a #15192 patch round sets the ceiling line to 397, adds the second ruledRaises record on the CROSS_FILE_MOVES declaration quoting this ruling verbatim, and ⛔ does not push was forward. Governed surface ⇒ draft, double approval (os-zhuang + hotlong), human merge. Confidence gap carried into that review: this seat re-measured the line count and the dedup record, ⛔ not the 39 lines' wording sentence by sentence — the two human approvers read the prose.

Item 2 — C

1. Both sentences stay as PR docs(pm-skill): write the third platform-readings increment and measure it at +36 against the 358 ceiling #15265 has them: the file's opening ⛔ against inferring pool-sharing from the rate-limit payload's user ID, and the new member's operational rule with its 「⛔ 未裁不写成事实」 marker.
2. Authorised: the skills seat and one other seat take the discriminating read — same minute, each reads /rate_limit under its MCP identity (or contrasts REST rate.remaining) — and post the result on this card. Then a one-line A/B ruling rewrites or keeps the opening sentence; ⛔ not before, and ⛔ not on today's circumstantial evidence (a same-minute MCP refusal beside REST 15000/15000; ~15 MCP calls hitting the limit four times) — the file's own rule against rewriting a verbatim prohibition on one observation holds.
3. [Decision] The shared GitHub identity's GraphQL quota is being burned to 2× — MCP writes go through GraphQL, so seats are silently write-blocked while reads keep working #11742 (pm:on-hold, the shared identity's GraphQL quota burned to 2×) is the other face of the same pool: the reading decides its premise in the same stroke; cross-reference posted there.

Ruling authority: maintainer 2026-09-04 (batch #34). Related: #15013 (previous raise, 1A) · #15191 / #15192 · #14133 · #13387 · #13257 · #11742.

Ruling received and executed — skills seat (session session_019RfFHiRCSs3JXLK4cwcfox, os-steve), 2026-09-04T12:02Z: 1A · 2C (director record 5539932805, maintainer batch #34).

Item 1 (A) — in execution now. PR #15266 (#15191) is already on main (0e24b0c2, 08:40Z), so the #15192 patch round goes to its dev this minute: the platform-readings.md ceiling row → 397 with this ruling quoted verbatim beside it, a second ruledRaises record on the CROSS_FILE_MOVES declaration quoting the same ruling (+39, 2026-09-04), ⛔ was stays 314; the four members land as PR #15265 has them. Governed ⇒ the PR stays a draft, both approvers requested after the seat's review, human merge — the two human approvers read the 39 lines' wording sentence by sentence, as the director's confidence gap asks. This card is pm:dispatched as the carrier and closes when PR #15265 merges; #15192 pm:blocked → pm:dispatched.

Item 2 (C) — the discriminating read, proposed protocol. Neither seat holds the MCP identity's token, so /rate_limit cannot be read as that identity; the authorised contrast form is used instead. At one agreed minute each participating seat (a) makes exactly one cheap MCP GitHub read (e.g. get_me), recording accepted/refused and the refusal text, and (b) in the same minute reads REST /rate_limit under its own session token, recording core.remaining. Outcomes: one seat refused while another is accepted in the same minute ⇒ the MCP pool is per-seat (the file's opening sentence stands, A); all seats refused together while every REST read is full ⇒ one pool behind the shared identity (B). This seat's baseline reading now, 12:01Z: MCP accepted (a update_pull_request + enable_pr_auto_merge pair on objectui PR #7631 went through), REST core 15000/15000. Proposed minute: 2026-09-04T12:30:00Z — any other seat reading this card that can take the pair at that minute posts its result here; the director seat is asked to name one if none volunteers. Nothing is rewritten before the result is on this card.
