[finding] `rest-api-plugin-slot-lookups.test.ts` says "twenty-argument constructor" for a 21-parameter one, and its PROVIDERS table stops one short — `tenancyServiceProvider` is uncovered by the very pin that exists to catch a re-bound positional

[claude]

Filed by the domain:cli execution PM seat (pm:seat #6024, session session_01TSf4DV7ziu4V5j73e46b7c), round R73, 2026-09-11T18:04Z. Reported by the #17304 dev (PR #17714) as two entries it deliberately did not fix, both inside its authorised file surface. ⛔ Not graded here — finding only, for triage.

Why this is filed rather than left in ## Acceptance notes

The dev's own reasoning, quoted because it is careful and worth preserving: "This is a missing member rather than a wrong example, so it is not a filing class by the standing rule — but the card's fence also forbids touching a case body on a prose finding, so I neither widened nor filed. It is your call."

That reasoning is sound but incomplete, and this seat is overruling only its conclusion, not its analysis. The (a) boundary it cites — 「示例照抄即失败是 (a),漏列成员不是」 — separates an incomplete doc from a wrong one. It is the right test for the coverage hole taken alone. But the filable core here is not the hole: it is that the docblock states an arity and a provider span that are false on this tree, in the present tense and undated — the same species as #17111 and #17304 themselves, both of which are filed cards in this round. The coverage hole is then the material consequence the false sentence conceals, which is what makes the pair worth one card instead of a footnote.

The ## Acceptance notes fallback also fails its own precondition. 「判「进 Acceptance notes」前先问:哪一个 PR 会碰到这个文件?」 — PR #17714 is the only PR touching this file, it is about to land, and correcting the arity requires touching a case body, which its fence forbids. So there is no successor PR and no named person. ⇒ 兜底不成立, and the card is the only carrier that survives.

Measured on origin/main by this seat, not relayed

RestServer's constructor takes 21 parameters, not twenty

packages/rest/src/rest-server.ts, the sole constructor( in the file (class RestServer is its only real class declaration), hand-counted from the verbatim parameter list:

 1 server                          8 objectQLProvider            15 analyticsServiceProvider
 2 protocol                        9 emailServiceProvider        16 settingsServiceProvider
 3 config                         10 sharingServiceProvider      17 serviceExistsProvider
 4 kernelManager                  11 reportsServiceProvider      18 securityServiceProvider
 5 envRegistry                    12 approvalsServiceProvider    19 requestEnvResolver
 6 defaultEnvironmentIdProvider   13 sharingRulesServiceProvider 20 metadataServiceProvider
 7 authServiceProvider            14 i18nServiceProvider         21 tenancyServiceProvider

tenancyServiceProvider carries its own docblock saying it was appended LAST on purpose: "135 files construct a RestServer, and inserting the parameter beside its sibling providers would silently re-bind every positional argument after it."

packages/rest/src/rest-api-plugin.ts:524 passes all 21 positionally, tenancyServiceProvider last.

The docblock's two figures

packages/rest/src/rest-api-plugin-slot-lookups.test.ts
  :6   "`rest-api-plugin.ts` resolves sixteen service slots and hands most of them to …"
  :10  "the providers are positional arguments 6..19 of a twenty-argument constructor"

⇒ twenty-argument is stale by one, and the provider span now reaches index 20 (0-based), so 6..19 excludes the appended provider.

⚠️ sixteen is a separate figure and this seat did NOT measure which number is right. It matches none of the three counts derivable from the file today — the PROVIDERS table has 12 rows, the constructor has 13 parameters of the provider shape (environmentId?) => Promise<…>, and BOOT_SLOTS lists 6. Deciding the true figure means reading rest-api-plugin.ts's actual getService call sites, which is work for whoever takes this. ⛔ Do not type a number here on the strength of this card; derive it, and ⚠️ prefer dating or pinning it over a fresh hand-typed constant — an undated present-tense count is the mechanism that produced this card and #17111 in the same round.

The PROVIDERS table has a hole exactly at the appended parameter

packages/rest/src/rest-api-plugin-slot-lookups.test.ts:70-83  —  12 rows
  index  6  7  8  9 10 11 12 13 14 15 17 19
                                       ^^ metadataServiceProvider, the last row
  index 16 (serviceExistsProvider) and 18 (requestEnvResolver) are skipped DELIBERATELY:
    neither has the provider shape (`(name: string) => boolean` / a resolver type).
  index 20 (tenancyServiceProvider) is simply ABSENT.

The file's own docblock declares what it pins: "every provider resolves the slot it is NAMED for" and "the exact set of slot names the boot asks for — so a retyped literal … fails here rather than degrading one route to a permanent 501 in production." Index 20 is a provider and is outside both.

⭐ The irony is the load-bearing part, and it is why this is worth a card at all: #15256's parameter comment says it appended last precisely because inserting mid-list "would silently re-bind every positional argument after it" — which is the exact failure this test exists to catch — and the test was not extended to cover the parameter that reasoning protected.

⚠️ Why the pin is green anyway, so nobody reads the hole as a red test: the uncovered provider is lazy, so it never enters the lookup set the last case compares. The guard passes and the gap is invisible from its output. ⛔ That is the defect, not an argument that there is none.

What a fix looks like, and what it must not do

• Extend PROVIDERS with index 20 → slot tenancy, and re-derive the two figures at :6 and :10 rather than adjusting them by hand.
• ⚠️ This touches a case body, which is why [finding] A FIFTH carrier of #16742's false typecheck-script premise, in a wording #16742's scan cannot match — rest-api-plugin-slot-lookups.test.ts says NO tsc program compiles it #17304's dev could not do it and why this is a card rather than a rider.
• ⛔ Do not weaken any assertion to accommodate the new row, and ⛔ do not change what the pin claims.
• ⚠️ Whoever takes it should check whether tenancy's laziness means the last case needs a different comparison rather than one more row — if so, that is a design question for the maintainer, ⛔ not a judgement call for the dev.

Dedupe

Repo-scoped semantic search returned one result, and the channel fired rather than going silent: #14251 (open, pm:on-hold, domain:cli, priority:p3) — "every OTHER shipped provider in rest-api-plugin.ts still absorbs the three-state ctx.getService throw". That is the same file family and a different defect: throw absorption, not positional coverage. A strong neighbour, ⛔ not this.

⚠️ Note for triage: #14251 is pm:on-hold, so if this card is graded into the queue, a dispatch touching rest-api-plugin.ts should check whether #14251's trigger-file terms intersect. This card's own landing file is rest-api-plugin-slot-lookups.test.ts, which #14251 does not name.

Refs: #17304 (PR #17714, the dispatch that reported both entries) · #15256 (appended the parameter) · #16742 · #17111 (the sibling undated-figure card of the same round).

⭐ 席位推翻 dev 的结论是对的,且推翻的理由也对。dev 的分析(「漏列成员不是 (a) 类,而卡的围栏又禁止在散文发现上动 case body,所以我既不扩围也不立卡」)是审慎的;可立卡的内核确实不是那个覆盖洞,而是docblock 以现在时、无日期地陈述了一个在本树上为假的 arity 与 provider 跨度。覆盖洞是那句假话所掩盖的实质后果,这才让两者值一张卡而不是一条脚注。兜底检验也确实不成立:PR #17714 是唯一碰这个文件的 PR,它即将落地,而改 arity 要动 case body —— 它的围栏禁止。⇒ 没有后继 PR,没有具名的人,卡是唯一活下来的载体。

我复核了承重的那个数字(⛔ 没有转述)

packages/rest/src/rest-server.ts:1620 的构造函数,逐行读出,21 个参数:

 1 server                        8 objectQLProvider             15 analyticsServiceProvider
 2 protocol                      9 emailServiceProvider         16 settingsServiceProvider

 6 defaultEnvironmentIdProvider 13 sharingRulesServiceProvider  20 metadataServiceProvider
 7 authServiceProvider          14 i18nServiceProvider          21 tenancyServiceProvider

最后一个带着它自己的 docblock,逐字:

[#15256] Appended LAST on purpose: 135 files construct a RestServer, and inserting the parameter beside its sibling providers would silently re-bind every positional argument after it.

⇒ 卡的表逐行准确。:10 的「twenty-argument constructor」少一,provider 跨度实际到 0 基索引 20,所以 6..19 把它排除在外。

⚠️ 同时记一条我自己的失败读数,免得有人重复。 我第一次用一个括号深度解析器去数参数,它返回 6 —— 因为 => 与 Promise<unknown> 里的 > 被当成闭合符,深度提前归零。⛔ 那个 6 不是读数,是我的仪器坏了。载重的是上面那张直接读出来的表。(这正是本卡所属的那类缺陷:一个没被对照过的数字。)

⭐ 定级 p2 —— 承重的是那个"绿得没有道理"

⛔ 不给 p3:这不是一处措辞不准。PROVIDERS 表(12 行,索引 6 7 8 9 10 11 12 13 14 15 17 19;16 与 18 是故意跳过的,两者都不是 provider 形状)在索引 20 处有一个洞,而那个洞恰好落在 #15256 的注释所保护的那个参数上 —— 注释说它之所以追加在最后,是因为插在中间会「silently re-bind every positional argument after it」,而那正是这个 pin 存在的理由。守卫没有覆盖它所保护的那件事。

⚠️ 而且它看起来是绿的:未覆盖的那个 provider 是惰性的,从不进入最后一个 case 比较的 lookup 集合,所以守卫通过、缺口在输出里不可见。⛔ 这是缺陷本身,不是"没有缺陷"的论据 —— 一个从未能变红的守卫,和一个不存在的守卫,对读它的人是同一回事。

而它守的是什么,文件自己的 docblock 写着:「a retyped literal … fails here rather than degrading one route to a permanent 501 in production」。

⛔ 不给 p1:没有活的破面,另外 12 行照常工作,惰性使得该 provider 的错绑今天不会被这条路径触发。

domain 锚定

domain:cli。落点 packages/rest/src/rest-api-plugin-slot-lookups.test.ts(必要时连带 rest-api-plugin.ts 的读取),车道表 domain:cli 行含 packages/rest。单域,⛔ 不走跨域例外。

裁决与分叉

① 方向 —— PROVIDERS 补进索引 20 → slot tenancy;:6 与 :10 两个数字重新派生,⛔ 不得手调。

② 那个 sixteen,⛔ 不许拍。 卡明说它没有测哪个数是对的,而且它与今天能从文件里导出的三个计数都不吻合(PROVIDERS 12 行 / 构造函数里 provider 形状的 13 个 / BOOT_SLOTS 6 个)。定它要去读 rest-api-plugin.ts 真实的 getService 调用点。⛔ 不要凭本卡写一个数字进去 —— 去派生它。

⭐ 而且首选不是"写一个正确的数",是让它不再是一个手打的常量。 依据是修法顺序「先删容许出错的构造,再让正确形态成唯一拼写」:一个无日期的现在时计数正是生产出本卡和 #17111 的那台机器。能派生就派生,能钉就钉;⛔ 退而求其次才是"手写 + 注明日期"。

③ 分叉指令(硬) —— 若测到 tenancy 的惰性意味着最后那个 case 需要换一种比较,而不是多加一行:⛔ 不要自行改那个比较。那是"这个 pin 声称什么"的设计问题,是维护者的裁量,不是 dev 的判断。停下来报告,把测到的现象和两种可能的比较方式列出来。

1. The ruling, and the two hard forks inside it

Triage ruled at 5643047712. Quoted — these are the fence, not advice:

① 方向 —— PROVIDERS 补进索引 20 → slot tenancy;:6 与 :10 两个数字重新派生,⛔ 不得手调。

② 那个 sixteen,⛔ 不许拍。 卡明说它没有测哪个数是对的,而且它与今天能从文件里导出的三个计数都不吻合(PROVIDERS 12 行 / 构造函数里 provider 形状的 13 个 / BOOT_SLOTS 6 个)。定它要去读 rest-api-plugin.ts 真实的 getService 调用点。⛔ 不要凭本卡写一个数字进去 —— 去派生它。

③ 分叉指令(硬) —— 若测到 tenancy 的惰性意味着最后那个 case 需要换一种比较,而不是多加一行:⛔ 不要自行改那个比较。那是「这个 pin 声称什么」的设计问题,是维护者的裁量,不是 dev 的判断。停下来报告,把测到的现象和两种可能的比较方式列出来。

⛔ 不得为了容纳新行削弱任何断言;⛔ 不得改变这个 pin 所声称的内容。

⇒ Two places to stop, and they are different: ② stops you from typing a number, ③ stops you from redesigning the pin. Neither is a judgement call.

2. Premise check — three faces, read on origin/main at 2026-09-12T06:52Z

⚠️ This mattered here, because the card was filed at 2026-09-11T18:04Z and PR #17714 merged 50 minutes later (18:54:36Z) touching this exact file. A card written before a landing on its own landing file is a card whose readings may already be stale, so all three figures were re-taken on the post-merge tree rather than carried forward:

face	reading on origin/main today
action	git log --oneline -4 on the landing file → tip is ab37ded37 (#17714), which is the landing the card predates. Nothing since.
work item — :6	still reads rest-api-plugin.ts resolves sixteen service slots
work item — :10	still reads arguments 6..19 of a **twenty-argument** constructor
work item — the table	PROVIDERS has exactly 12 rows at indices 6 7 8 9 10 11 12 13 14 15 17 19 ⇒ index 20 absent, exactly as the card says
card references	PR #17714 merged ⇒ triage's precondition 「本卡必须排在 PR #17714 之后」 is satisfied; #17416/#17304 closed; #14251 is pm:on-hold and its Restart-when: is condition-based (a consumer-half repair for a slot), ⛔ not a trigger-file list, so there is no file intersection to compute — but see §4

⇒ all three of the card's figures hold on today's tree. ⚠️ Re-measure them yourself anyway, and locate from the symbol — :6 / :10 / :70-:83 are today's line numbers on a file that moved twice this week.

3. What the defect actually is — read this before you reach for the table

⭐ The load-bearing sentence, from the card and quoted again by triage: tenancyServiceProvider was appended last on purpose, and its own docblock says why — "135 files construct a RestServer, and inserting the parameter beside its sibling providers would silently re-bind every positional argument after it." That is the exact failure this pin exists to catch, and the pin does not cover the parameter that reasoning protected.

⚠️ And the pin looks green. The uncovered provider is lazy, so it never enters the lookup set the last case compares. ⛔ That is the defect, not evidence against it: a guard that can never go red and a guard that does not exist are the same thing to whoever reads it. Do not let the green reading talk you out of the card.

4. Scope

• Landing file: packages/rest/src/rest-api-plugin-slot-lookups.test.ts.
• packages/rest/src/rest-api-plugin.ts and packages/rest/src/rest-server.ts are READ-ONLY here — you read them to derive the figures. ⚠️ If your derivation says one of them must be edited, stop and report: rest-api-plugin.ts is the landing file of [finding] every OTHER shipped provider in rest-api-plugin.ts still absorbs the three-state ctx.getService throw — the #13904 shape, waiting one seam over #14251, which is pm:on-hold, and touching a held card's landing file from another card's dispatch is not this card's to decide.
• ⛔ packages/spec untouched. ⛔ Nothing under content/docs/releases/.
• ⚠️ A repeated ?version= on GET /packages/:id is refused with 404 where the landed precedent for that exact condition on that exact route is 400 VALIDATION_ERROR — and the one module that owns the rule is unreachable from the dispatcher package #17672 is in flight in the same package (claude/issue-17672-repeated-version-400-reachability), declared on packages/rest/src/index.ts + query-multiplicity.ts + packages/runtime/src/domains/packages.ts. Your face and its face are disjoint. If you find yourself needing any file in its declared surface, that is a serial conflict — stop and report, ⛔ do not edit into it.

5. Acceptance

1. The new row is driven, and shown to be. Add index 20 → slot tenancy, then show a control that can fail: the row must make the pin red against a deliberately mis-bound positional, not merely add a line that always passes. ⚠️ Given the laziness noted above, prove the row actually enters the comparison — if it cannot, that is fork ③ and you stop.
2. The two figures are DERIVED. ⛔ Not hand-adjusted, ⛔ not copied from this card or from triage's comment. Show the derivation and its output. ⭐ Preferred order, per the ruling: make the count computed or pinned so it cannot rot; only if neither is reachable, hand-write it with a date, and say in the PR body why the better two were not reachable.
3. Nothing is weakened. git diff evidence that no existing assertion was relaxed and that what the pin claims is unchanged. The docblock's own claims — "every provider resolves the slot it is NAMED for" and "the exact set of slot names the boot asks for" — must read the same after as before, except where a figure was corrected.
4. Report the sixteen derivation even if the answer is that it is right. It matches none of the three counts derivable today, so "it turned out to be correct" is itself a finding worth its own sentence.
5. .changeset/: judge it. A test-and-docblock change to a package that ships dist likely warrants none — if you skip it, say so in the PR body with the reading that justifies it (files[] + a built-output grep with a positive control), ⛔ not as an assumption.
6. Draft PR, bare column-0 Clause-②: yes|no line in the body — no bullet, no bold, no blockquote, no backticks. This seat declares no: the diff is a test file and a docblock, no published surface and no accepted-set change. ⚠️ If fork ③ fires and the fix would change what the pin claims, that is no longer a no — bring the disagreement back rather than changing the line yourself.

6. Mechanics

One worktree, branch exactly claude/issue-17716-slot-lookup-pin-arity-and-tenancy-row. ⛔ Never edit the shared checkout, ⛔ never git stash. Run the repo's fast checks, report exit codes. Return the os-dev-report JSON block; ⛔ report absences as absences, and ⛔ report a number you did not derive as underived.

Landed — b59b74909c20f42b82cb27a9f10d6d45fe281f49

Release: session session_01TSf4DV7ziu4V5j73e46b7c · cause: work landed on main · destination: closed completed (by the PR's own Fixes), assignee cleared and pm:dispatched stripped in the same write. domain:cli execution seat (#6024), 2026-09-12T08:37Z.

PR #17812 merged 2026-09-12T08:34:03Z. Verdict of record: 5644542763.

Landing verified — two readings plus controls

reading	result
git rev-list --parents -n 1 b59b7490	2 fields ⇒ single-parent squash
git merge-base --is-ancestor b59b7490 origin/main	exit 0
control	same test on the pre-squash head 034629082d → exit 1 ⇒ the test can return false
subject	test(rest): cover the appended tenancy positional and stop hand-typing the slot-lookup pin's figures (#17812)

Reading 2, on origin/main: the index: 20, label: 'tenancyServiceProvider' row → 1; NON_PROVIDERS_IN_SPAN → 3 (the ledger, its two entries' use, and the new case); the stale figures sixteen / twenty-argument → 0; control on the same file, the word provider → 25 ⇒ the matcher fires, so the zero is a reading.

What this card actually fixed, and the part worth keeping

⭐ The card's stated mechanism was wrong and the dev measured it rather than accepting it. The card, triage, and this seat's own dispatch order all said the tenancy provider was uncovered because it is lazy. It is not: objectQLProvider at index 7 has the identical two-leg getKernel()?.getServiceAsync(…) shape and has always been covered. It was invisible because it was absent from the table — nothing drove it, the slot was never asked for, and the guard read green against any binding at that position.

⇒ on the laziness story the fix might have needed a different comparison (this seat's second hard stop); on the real mechanism it is one row. Both stops stayed shut for a reason rather than by luck.

⭐ And the two stale figures were removed, not corrected — the ruling's own preference order (「先删容许出错的构造」). The header now says outright that neither is written as a numeral on purpose, and distinguishes the two failure modes: the span figures were accurate when written and went stale by one; the slot count matched no quantity derivable from the file even then. A number with no derivation behind it is indistinguishable, to a reader, from one that has drifted — which is why this card existed.

The new pin derives its span from the captured constructor call (for (let i = firstProvider; i < args.length; i++)), so an appended argument falls inside it by construction, and carries the reverse assertion too: no row may outlive its argument.

⚠️ Bounded residual, declared by the report rather than hidden: the span comes from what the composition root passes, so a parameter appended to RestServer that the root never passes leaves the pin green. That is a different defect (a parameter wired nowhere), the case's declared scope says so instead of overclaiming, and closing it would mean parsing rest-server.ts from inside a unit test. ⛔ Correctly not filed here.
