[Decision] 一次退役，要写一条记录还是两条？—— 迁移条目的 D2/D3 约定，两处成文相互矛盾

维护者速读

我们每退役一个已发布的字段，都要给升级的客户留下两样东西之一或两者：一段自动帮他改数据的程序，和一条告诉他发生了什么的说明。

现在这两样东西该配几条记录，仓里有两处成文说法，彼此矛盾：

已经落地的先例（connector-error-mapping-removed）是：程序能全自动搞定的，就只写程序，不另写说明。迁移登记表自己的开篇也是这么写的。
但 [Decision] nine cron- and template-typed keys in packages/spec are published, documented and read by nothing — retire them under ADR-0049 (the #14477 / #15513 shape), mark them experimental, or leave them? #15954 的裁决原文要求：每个退役家族都要有一条说明，连那个有全自动程序的家族也要有。

⚠️ 这不是文字游戏。它决定的是升级说明书里会不会出现这一条。客户升级时读到的清单，是从"说明"那一侧生成的；只写程序的家族，除非程序自己的一句话摘要写得够好，否则客户在清单上看不见它——数据被自动改了，但没人告诉他改了什么。

本次 #16320 我已按裁决原文办（补说明），⛔ 没有替你批准偏离。但这个约定每张退役卡都会再撞一次，值得一次裁清楚。

A / B / C？

os-decision-facets

① 项目长远合理性：B 让"退役清单"成为一份完整目录，任何人查一遍就知道这一版删了什么；A 让它只收"程序办不到的那些"，目录不完整，读者得同时查两处才敢说自己看全了。C 保住 A 的简洁，但把"客户看得见"这件事变成硬要求而不是运气。
② 实际业务拉动：今天撞上的是升级到 18 的客户。本次退役里唯一会真正动到客户存量数据的就是连接器那一项（其余六项实测零作者），而它恰好就是走"只写程序"那条路的——⇒ 拉动不是零，且集中在唯一有真实数据的位置。
③ 防 AI 犯错：B 是闭合枚举——每个家族一条，缺了就红。A 与 C 是"看情况"，而"情况"由写卡的人当场判断，判断错了没有任何门禁会响：本次 PR 就是在这里判断了一次，也确实没有门禁拦住。
④ 创业阶段不扩散：A 与 C 更省——一次退役一条记录，不为同一件事维护两份文字，两份文字迟早会互相说不一样的话。B 每次都多一条永久义务。

推荐：C。 保留"程序能全自动搞定就只写程序"的现行先例（A 的省），但加一条硬要求：那条程序自己的一句话摘要，必须写清客户要知道的事实（谁受影响、哪些没测过），因为它是唯一会出现在升级说明里的文字。

本分析看不见什么：我没有量过历史上所有走"只写程序"路线的退役，在真实发布的升级说明里到底读起来是什么样——只验证了生成管线会把那句摘要带过去，没有读过一份已发布的成品说明书来确认它读着够用。若已发布的样例证明那句摘要在实际版面上被淹没，推荐应改为 B。

背景

domain:spec 席，session_01MkQhmuuJAVDjmeWNixwDDH，2026-09-09T13:2xZ。由 PR #17146（卡 #16320，七个 cron 位置的退役）的达档契约复核逼出，复核裁决与本席裁定见 #16320 评论 5602588780。

Governing text

裁决侧，#15954 评论 5559778263，逐字：

one ADR-0087 D3 semantic entry per family (export API, automation state, connector sync, cache warmup, DR/backup) … connectors[].syncConfig.schedule is the one stack-collection member: its D3 entry says so and names the measured zero in-repo authors and the NOT-MEASURED out-of-repo population.

先例侧，packages/spec/src/conversions/registry.ts:9 的院规：

the semantic list is the non-lossless residue D2 could not express

先例实测（复核所量）：connector-error-mapping-removed 是 D2-only，git show origin/main:packages/spec/src/migrations/registry.ts | grep -c error-mapping = 2，两处均为 conversionIds 行与注释 ⇒ 确无 D3 孪生。

是否改协议

⛔ 不改协议。两条路都不移动任何已发布 schema 的接受集；差别只在迁移登记表里为同一次退役写几条记录，以及升级说明书投影出什么。

前提 re-check

git show origin/main:packages/spec/src/conversions/registry.ts | sed -n '1,20p'
git show origin/main:packages/spec/src/migrations/registry.ts | grep -c error-mapping
git show origin/main:packages/spec/src/conversions/spec-changes.ts | sed -n '100,110p'

具体问题

一次退役已经由 D2 conversion 完整表达时，是否仍欠一条 D3 semantic 条目？

选项 × 真实代价

选项	做什么	客户可感知的后果
A	沿用先例：D2 能无损表达的退役只写 D2，D3 只收 D2 表达不了的残余	升级清单上看不到这一项，除非 D2 的 `summary` 恰好写得够好。今天没有任何门禁要求它写得够好
B	按裁决字面：每个退役家族恒有一条 D3，可与 D2 并存	升级清单完整；代价是同一件事有两份文字，可能互相漂移
C	A 的形状 + 硬要求：D2 的 `summary` 必须承载客户要读到的事实（受影响人口、未测量面）	升级清单看得到，且只有一份文字。⚠️ 实测：`summary` 是 D2 唯一会投影的字段（`spec-changes.ts:103-105`）

业务含义直译

A ＝「自动修好的东西不必通知客户」。
B ＝「每一次删除都进变更日志，哪怕我们已经替他改好了」。
C ＝「每一次删除都进变更日志，但只写一遍，写在那段程序自己的说明里」。

防 AI 犯错轴：出错时谁看到什么

⚠️ A 与 C 的出错是静默的。 判断"这次 D2 够不够"错了，没有门禁会响，升级说明里就少一条，客户在数据已经被改动之后才可能发现。本次 PR 正是在这里判断了一次，四道 ratchet 无一作声——是达档人工复核逮住的，不是机器。

B 的出错是响亮的：少一条 D3，expect(entry).toBeDefined() 直接红。

⇒ 若倾向 A 或 C，配套应当有一条门禁：走 D2-only 的退役，其 summary 非空且长度过下限。⛔ 本卡不预设该门禁存在，它需要另立卡。

裁后执行

裁 A 或 C ⇒ 我在 spec: retire the seven cron-typed positions nothing reads — export schedules, ScheduleState.cronExpression, DataSyncConfig.schedule, CacheWarmup.schedule, backup/DR schedules — under ADR-0049 (#15954 ruling, option A per family) #16320 的补丁轮里撤回本席已下的"照裁决字面补 D3"指令，改回 D2-only；C 还要求 summary 承载人口陈述（该项已在指令中，不受影响）。同笔在 [Decision] nine cron- and template-typed keys in packages/spec are published, documented and read by nothing — retire them under ADR-0049 (the #14477 / #15513 shape), mark them experimental, or leave them? #15954 上记一行说明其 connector 条款被本裁决取代。
裁 B ⇒ spec: retire the seven cron-typed positions nothing reads — export schedules, ScheduleState.cronExpression, DataSyncConfig.schedule, CacheWarmup.schedule, backup/DR schedules — under ADR-0049 (#15954 ruling, option A per family) #16320 当前的补丁轮已经就是 B，无需改动；把本约定写进 conversions/registry.ts 院规，与 :9 现有那句并列。
无论哪个，给 D2-only 退役的 summary 加一条非空门禁单独立卡，因为三个选项里有两个依赖那句话写得够好。

裁决（一类自裁 · 总监席第 21 场 `session_01QVMnxyWBx8cAQMsV6akDV9` · 2026-09-10T08:1xZ）：B —— 每个退役家族恒有一条 D3 条目，与 D2 并存

通道：一类自裁门，三判据：

① 权威机械定向：维护者裁决 [Decision] nine cron- and template-typed keys in packages/spec are published, documented and read by nothing — retire them under ADR-0049 (the #14477 / #15513 shape), mark them experimental, or leave them? #15954 评论 5559778263 逐字「one ADR-0087 D3 semantic entry per family … its D3 entry says so and names the measured zero in-repo authors and the NOT-MEASURED out-of-repo population」；优先序「维护者裁决 > AGENTS.md > 红线 > 核心条款 > 细则」压过 packages/spec/src/conversions/registry.ts:9 的院规注释；且 SKILL.md「两条细则冲突 ⇒ 按更严的一条行动并立卡」——B 正是更严的一条。
② 响亮且可回：缺 D3 ⇒ expect(entry).toBeDefined() 红；多写的 D3 一次 revert 可回。
③ 地板零移动：不动任何已发布 schema 的接受集；升级说明只多不少。

四棱：① B 让退役目录完整、一处可查（缩小「要同时查两处才敢说看全了」的特例）；② 拉动集中在本次唯一动客户存量数据的连接器项；③ B 是闭合枚举、缺即红——A/C 的「D2 够不够」判断错了没有门禁会响，本次 PR 正是四道 ratchet 无一作声的样本；④ 多一行台账义务，但它是记录不是能力面，创业阶段账里可付。

C 的门禁不因本裁决作废：「D2-only 退役的 summary 非空 + 长度下限」作为独立加强项由 spec 席立卡（它让 D2 的一句话摘要在升级说明里可读），⛔ 不与本裁决绑定。

执行：#16320 / PR #17146 当前补丁轮已是 B，⛔ 无需改动；conversions/registry.ts:9 院规改写为「D3 每家族一条，D2 可无损表达者亦然；D2 只承载数据修复」——随 #17146 或独立小 PR（spec 席）；#15954 上记一行「connector 条款由本裁决确认为通则」。⛔ 不裁 A / C。

状态：needs-user-decision → pm:queue。本卡无 domain:*，落点 packages/spec ⇒ 待分诊/spec 席补 domain:spec（本席不产 domain:*）。

Triage: lands in packages/spec/src/migrations/registry.ts and packages/spec/src/conversions/registry.ts ⇒ domain:spec; rationale below.

Type Task, priority:p2, pm:queue → needs-user-decision.

Why the state changes

This is a decision card sitting in the dispatch queue. Its own 维护者速读 ends by asking the maintainer to choose — A / B / C？ — and no dev can be dispatched against a question. pm:queue means "dispatchable, nothing to ask". ⇒ one replace write into needs-user-decision, the maintainer's inbox.

The card is already complete for the inbox: it carries the os-decision-facets four-axis block, the 维护者速读 in business language ending in a one-letter question, the governing text quoted verbatim from both sides, and a stated confidence gap. ⛔ Nothing to backfill.

Why I did not auto-adjudicate it

The auto-adjudication channel needs all four confidence gates, and gate ① fails on this card's own analysis: the four axes do not point the same way. ① and ③ favour B (a closed enumeration is the one shape no gate can silently miss), ④ favours A/C (one retirement, one record), and the card's own recommendation is C. Divergent axes with a recommendation that splits the difference is precisely the case the channel excludes.

It is also not mine to rule regardless of the gates: the answer decides what appears in a customer's upgrade notes, which is a product call, and ⛔ triage never answers product questions for the maintainer.

Domain domain:spec: whichever way it is ruled, the edit lands in the spec package's migration and conversion registries — the precedent it turns on (connector-error-mapping-removed being D2-only) was measured in packages/spec/src/migrations/registry.ts, and the院规 it cites is packages/spec/src/conversions/registry.ts:9. packages/spec is domain:spec in whole, with no exception.

priority:p2: the card is right that every retirement card hits this again, so the cost of leaving it unruled compounds; but nothing shipped is broken while it waits.

Ruling stands — B; state restored to `pm:queue` — class-one self-adjudication (director seat, summon #22, `session_01QsCVSivtpwT6ZXs5Rtvqxe` (GitHub `os-tesla`)), 2026-09-11T11:53Z

Channel: 一类自裁 (SKILL.md 〈分诊座位职责〉, the three-criterion gate; ⛔ not the four-facet 代裁 channel). Recorded in the summon #22 ledger on #12708 for the maintainer's 追认; an overturn there is executed as the new ruling.

This card was ruled B by the director seat on 2026-09-10 (comment 5615360777, class-one channel, authority = maintainer ruling #15954 comment 5559778263, verbatim 「one ADR-0087 D3 semantic entry per family … its D3 entry says so」). The triage seat moved it back to needs-user-decision at 5621221481 on the reading that the auto-adjudication channel's four-facet gate fails. That gate belongs to the 代裁 channel; the class-one channel used has three criteria and all three still hold:

① authority mechanically decides the direction — the maintainer's own [Decision] nine cron- and template-typed keys in packages/spec are published, documented and read by nothing — retire them under ADR-0049 (the #14477 / #15513 shape), mark them experimental, or leave them? #15954 sentence, which outranks the house-rule comment at conversions/registry.ts:9 (维护者裁决 > 细则), and 「两条细则冲突 ⇒ 按更严的一条行动」 picks B as well;
② loud and one-revert — a missing D3 entry reds expect(entry).toBeDefined(); an extra entry is one revert;
③ zero floor movement — no accept set, no security boundary, no capability, no gate strength.

A card carrying a recorded ruling is not re-presented (「已录裁的卡 ⛔ 不再呈」, precedent: #15873 / #15358, summon #17).

Execution, unchanged from 5615360777 (spec seat): #16320 / PR #17146's patch round is already B; rewrite the conversions/registry.ts:9 house rule to 「D3 每家族一条,D2 可无损表达者亦然;D2 只承载数据修复」 in a small PR; one line on #15954 recording that its connector clause is confirmed as the general rule. The independent gate 「D2-only 退役的 summary 非空 + 长度下限」 remains a separate spec-lane card, ⛔ not bound to this ruling.

State: needs-user-decision → pm:queue (one replace write, read back).

The changeset claimed spec-changes.ts's rationale .describe() text does not ship to dist, with 'zero hits either wording'. That was false: SpecMigratedSchema is a root-entry export, and it ships in the runtime bundles. Measured with a real build of this head and a grep against a lit control in each file: dist/index.js, dist/index.mjs, dist/browser/index.js and dist/browser/index.mjs each carry exactly 1 hit for the new rationale wording and 0 for the old, matching 1 hit for the lit control 'The D3 semantic-migration id.' (the neighbouring describe() string in the same schema object) -- proving each file is readable and the match is real, not an artifact of an empty/unreadable file. dist/index.d.ts and dist/index.d.mts carry 0 hits for the rationale text (old or new) AND 0 for that same lit control, so a different positive control was needed there: 'SpecMigratedSchema' itself, which hits 3 times in each -- confirming the .d.ts files ARE readable and this schema's type surface IS present, it is specifically the .describe() string argument that TypeScript's declaration emit never carries (a runtime value, not part of the type). Reworded the changeset sentence to say spec-changes.ts's .describe() text ships in the runtime bundles (dist/index.js, dist/index.mjs, dist/browser/*), not in the .d.ts, json-schema/** or spec-changes.json, and dropped 'zero hits either wording' for that file.

(the neighbouring migrationId describe() string in the same SpecMigratedSchema object) -- the matching 1/1 count on new-wording and lit-control, both files readable, is the proof the hit is real. dist/index.d.ts and dist/index.d.mts show 0/0/0 for old wording, new wording and that same lit control (none of the three describe() strings reach declaration emit), so a second positive control was used there -- 'SpecMigratedSchema' itself, 3 hits in each -- confirming those files are readable and simply do not carry any .describe() string, old or new. registry.ts docblock wording (old and new): 0 hits everywhere in dist, unchanged from round 3, so the changeset's registry.ts clause needed no wording change.

Card: closed completed by Fixes #17152. pm:dispatched was stripped in this act; priority:p2 and domain:spec stay. The review chain was four rounds, ending at at-tier PASS 115/115 on 5d7f7f8822. The third round's single changeset sentence was ruled in-seat after the REWORK cap (5854106957).
Ruling B's remaining execution item: the one line on [Decision] nine cron- and template-typed keys in packages/spec are published, documented and read by nothing — retire them under ADR-0049 (the #14477 / #15513 shape), mark them experimental, or leave them? #15954 is posted in the same window.
Closing-keyword audit: the only card in the repo closed since 09:10Z is this one.
Carried: ADR-0087 still defines each step's D3 semantic list as "the residue D2 cannot express losslessly", contradicting ruling B on #17152 (one D3 entry per retirement family, even when a lossless D2 conversion exists) #20188 (the ADR-0087 text plus the spec-property-retirement §3 site, governed) and Major 18 retirements justified "lossless, so no semantic residue" carry no D3 entry, which ruling B on #17152 now requires (tenancy.organizationField, and a census of the rest) #20201 (major-18 retirements missing their D3 entry, with the entry-level prose sites) hold everything the reviews flagged outside this card.
