Fix the SCIM parity gate's constructor call so it actually prints the seven-model diff against @better-auth/scim 1.7.1

[claude]

Filed by the triage seat (session session_01LsWeHbPzR3i6mmonFfGykk, 2026-08-23) executing the maintainer ruling on #3653 (verbatim: 「10950 不考虑存量，其他接受你的建议」, accepting: fix the parity gate first, rule the migration path on the real diff).

What

The rc.2/1.7.1 parity gate dies in its collection phase with a TypeError before it can print the seven-model diff it promises (measured on #3653, dev report comment 5386605190). Fix the constructor call so the gate reaches the diff-printing stage against @better-auth/scim 1.7.1 (the stable rewrite: seven new models + conditional managed-connections directory), and attach the produced diff to #3653.

Scope

Gate repair + one diff run + posting the diff. ⛔ NOT the migration itself — #3653 holds the migration decision and is parked on this card; the maintainer rules the path once the diff exists. Sibling fact card: #11372 (workspace comment undercounts the models — seven + 3 conditional, not six).

Acceptance

The gate run completes and the seven-model diff (plus managed-connections delta) is posted on #3653.

Claim: domain:services execution seat, session session_01APWX2AwT3a4xDcjPCe8bk4 (os-sam). Branch claude/issue-11380-scim-parity-gate-ctor. R7 batch.

pm:queue → pm:dispatched + assigned in one write, before this comment. An earlier claim under a different session ID outranks this one — say so and I stand down.

Decision re-read done. This card was filed by triage executing the maintainer ruling on #3653 (3653#issuecomment-5386678763), which parked the migration decision and made this card its unblocker:

Ruled: repair the parity gate first, then rule the migration path on the real seven-model diff — the card's four load-bearing claims were overturned by measurement […] so the migration fork is not ripe. needs-user-decision → pm:blocked; the gate repair is filed as #11380 and this card returns for its ruling when the diff is posted here.

Zone 1 — scope. ⛔ Hard boundary.

Gate repair + one diff run + posting the diff on #3653. That is the entire deliverable.

⛔ NOT the migration. ⛔ Do not upgrade the @better-auth/scim pin (plugin-auth/package.json:29, currently 1.7.0-rc.1). ⛔ Do not touch auth-manager.ts's scim({...}) call. ⛔ Do not delete either scaffold peerDependencyRules.allowedVersions suppression — those retire with the migration, not with this card. ⛔ packages/spec zero ownership — the SCIMGroupSchema question is #3653's, not yours.

#3653 is pm:blocked on this card. The faster and narrower this lands, the sooner the maintainer has a real diff to rule on. A wide PR here delays the thing it exists to unblock.

Zone 1 — the measured defect. ⛔ Do not re-derive.

From #3653's dev report 5386605190:

The parity gate dies in its collection phase with a TypeError before it can print the seven-model diff it promises. The diff only appears after the constructor call is fixed.

⚠️ And the reason this matters beyond tidiness, which should be stated in the PR body: the gate was written down on #3653 as the safety net for the migration moment — "the gate will report all seven model differences the instant you upgrade". It does not open at the promised moment. A migrator hits an uninformative TypeError instead of a model-difference list. That is a declared-not-enforced guard, and repairing it is the point.

Zone 2 — my mechanism assumptions. ⚠️ Falsify me; measurement wins.

1. The failure is a constructor call-shape mismatch — the gate constructs a vendor object with an argument shape 1.7.1 no longer accepts — and the repair is at the call site, not in the gate's comparison logic. ⚠️ If the diff logic downstream is also written against the five-model world and would produce a wrong or empty diff even once collection succeeds, that is in scope (the acceptance is a correct diff, not merely a non-crashing run) — but say plainly which of the two you found.
2. The gate can reach 1.7.1 without the workspace moving to it — via a devDependency, an explicit version fetch, or whatever the gate already does. ⚠️ If reaching 1.7.1 requires moving the workspace pin, stop and report: that is the migration, and it is SCIM: 停在 @better-auth/scim rc.1,等正式版再整体迁移 —— rc.2 换掉了整套模型 #3653's ruling to make, not yours to fold in.
3. Seven models plus a conditional managed-connections directory (3 further models) is the expected shape. Do not treat "seven" as a target to make the output match — report what the gate prints, and if it is not seven, that reading is more valuable than a tidy one.

Zone 3 — suggested route

Reproduce the TypeError first and quote it, so the repair has a before. Fix the call. Run the gate. Post the produced diff — the actual output, not a summary of it — as a comment on #3653, since that is where the ruling resumes. Cross-link from here.

Clause-② — no

Judged from card content, not paths: this repairs a gate's own construction so it reaches its diff-printing stage. It changes no product accept/reject behaviour and widens no public surface. ⚠️ If your repair turns out to require touching product code rather than the gate, re-grade and tell me — do not carry a no that stopped being true.

Standing operational note from #3653, unchanged and still true: SCIM is default-off; group provisioning is not wired — deployments with SCIM enabled must not let the IdP push groups until the migration lands.

Method requirements

• Gate union from node scripts/pm/dispatch-gates.mjs with no hand-supplied paths. PREREQUISITE NOT MET and lock exit 99 are NOT MEASURED — never report either as a pass.
• Zero-hit needs a reverse control before it counts.
• ⛔ Worktree-first, per repo. ⛔ Never git stash. ⛔ Never touch content/docs/releases/**.

Diff produced and posted. The repaired gate's run against the published @better-auth/scim@1.7.1 is on #3653, verbatim: #3653 (comment) — that is where the migration ruling resumes.

Draft PR: #11429. Gate-only (one test file), skip-changeset; the pin, auth-manager.ts, both scaffold suppressions and packages/spec are untouched. 1.7.1 was reached through the gitignored pnpm virtual store, so no tracked manifest moved.

Reading, in one line: seven unmapped models where four are acknowledged, scimProvider gone, ten models if managedConnections is ever configured — and on the pinned rc.1 the gate is unchanged at 24 passed (24).

Zone 2 answered: (1) it is a CONSTRUCTOR call-shape mismatch, not broken comparison logic - stable's factory calls validateConnections(options) as its first statement and reads options.connections.length before any existence check, so scim({} as never) in the describe body and the for header kills the file at COLLECTION; once construction succeeds the downstream diff logic is correct and instructive with no change needed. (2) 1.7.1 was reached WITHOUT moving the workspace pin - the published tarball was unpacked into the gitignored pnpm virtual store and the package's node_modules symlink pointed at it per run, trap-restored; pin, auth-manager.ts, both scaffold suppressions and packages/spec are untouched, so clause-2 stays 'no'. (3) The gate prints exactly SEVEN unmapped models against the four acknowledged, plus scimProvider disappearing; the conditional managed trio (10 models) is measured separately by probe because the gate deliberately does not configure managedConnections. Process note the PM should have: the branch was NOT empty - the previous dev had one unpushed commit in a live worktree at /home/user/objectstack-11380.

Reverse control: injecting one deliberate type error into the edited file moves the count to 99 and prints 'better-auth-schema-parity.test.ts(699,7): error TS2322' - the instrument can see this file, so the zero delta is a measurement, not a blind spot.

PM 复核 PR #11429 —— ACCEPT。⛔ 尚未翻牌(CI 未收敛),已挂自检回来完成

复核对象是树与 diff。⭐ 本卡的存在理由已经兑现:diff 已贴在 #3653(5387582046),逐字原文,而 #3653 已因此从 pm:blocked 移回 needs-user-decision。

硬边界:全部守住

diff 是恰好一个文件,better-auth-schema-parity.test.ts,+93/−3。

⛔ pin 仍是 1.7.0-rc.1(plugin-auth/package.json:29)· ⛔ auth-manager.ts 未动 · ⛔ 两处脚手架 peerDependencyRules 抑制未动 · ⛔ packages/spec 未动。⇒ Clause-② no 成立,不是继承的。

它是怎么在不移 pin 的情况下读到 1.7.1 的:把发布的 tarball 解到 worktree 的 gitignored pnpm 虚拟仓库,按 run 把包的 node_modules 符号链接指过去,trap 在 EXIT/INT/TERM 还原。每次读前都取磁盘证据(resolved version: 1.7.1、1.7.1-only 标记 scimManagedConnection = 15、rc.1-only 标记 scimGroupRoleGrant = 0,rc.1 侧反之)。⇒ 不是「相信它换过去了」,是每一腿都证明了自己在读哪个产物。

Zone-2 三条,全部答到点上

①「是构造调用形状不匹配,不是比较逻辑坏了」—— 确认,而且给出了为什么必然死在 collection:稳定版工厂的第一条语句就是 validateConnections(options),它在任何存在性检查之前读 options.connections.length;而 schema 在 describe 体和 for 头里都要读 ⇒ 抛在收集阶段,整个文件死掉,打印 TypeError 而不是它承诺的模型清单。构造成功之后下游比较逻辑正确且有信息量,无需改动。

② 未移 pin —— 见上。

③ 恰好七个 —— 而且是报出来的,不是凑出来的。我在派发里写死「⛔ 不许把七当成目标去迎合」,它照办,并把条件性 managed 三件单独用探针测、明说门禁刻意不配置 managedConnections(auth manager 不传它,配了就会让门禁去比一个没有任何 ObjectStack 部署会 provision 的面)。

⭐ 两条对照,一条证明无回归,一条证明没变窄

• LEG A vs LEG E —— 在钉住的 rc.1 上,修复后与修复前都是 24 passed (24)。⇒ 这次修复对 CI 实际跑的那个版本零影响;它改变的只是「pin 移动那一天会发生什么」。这是无回归的直接证据,不是论证。
• LEG F 选项形状等价性 —— 便宜构造(connections: [] + 从不被调用的 verifyBearerToken)与真实静态连接得到 SETS EQUAL: true、每个模型列集相等。⇒ 「最便宜」不等于「比较得更少」,这正是这类修复最容易悄悄变成窄化的地方。

⭐ 而且该探针的第一次尝试失败了:缺 credentials 的连接项在 index.mjs:7058 抛同样的 TypeError。这次失败被写进文件的 docblock,而不是悄悄重试掉 —— 一个「半配置的输入并不比空输入更小」的事实,下一个人不必再撞一次。

⭐⭐ 一处棘轮意识,我独立验过

constructScim() 把 vendor 错误拼进 message 字符串,而不是用 new Error(msg, { cause })。注释给的理由是:本包编译在 lib: es2020,ErrorOptions 不存在,那种写法是 TS2554,会落进 plugin-auth shrink-only 的 TEST_DEBT 计数。

我核了: 根 tsconfig.json 是 "target": "ES2020" / "lib": ["ES2020"],plugin-auth/tsconfig.json extends 它。ErrorOptions 是 ES2022 才有的。⇒ 理由成立。 而 cause 仍通过 Object.assign 挂着,供会拆包的读者用。

⚠️ 顺带印证了另一件事:plugin-auth/tsconfig.json exclude 了 **/*.test.ts —— 这正是它必须自建一个「TEST_DEBT 形状的 tsc 工程」(package tsconfig + 显式 files 列表还原隐藏的 116 个测试文件)才能测到这条改动的原因。97 → 97 零变化,并带反向对照:注入一个故意的类型错误使计数变成 99 并点名该文件 ⇒ 仪器看得见这个文件,所以那个零是测量,不是盲点。

最耐久的部分:让下一次失败可读

裸的 vendor TypeError 读起来像「门禁坏了」—— 而上一次它就是这样让一个迁移轮报废的。现在构造失败会重抛一条指名道姓的错误:这是构造不匹配,不是 parity 失败,请更新 SCIM_GATE_OPTIONS 到该版本接受的形状,然后读门禁打印的模型差异。

⇒ 这把一次「declared-not-enforced」修成了声明即强制,并且把下一次版本漂移的诊断成本从「读源码猜」降到「读错误信息」。

状态

CI 在 7544c02b5b 上:29 项完成全绿、零失败,Test Core (1/6) 与 Lint & Repo Gates 仍 in_progress。4 项 skipped 为路径过滤/被取代运行的重复条目。

⛔ 尚未翻牌。Clause-② no ⇒ 收敛全绿后由本席直接翻牌入队,不需要契约复审档位。

⚠️ 已挂自检回来完成翻牌。 本车道今天有过一次同形失误(#10692:复核写了「暂不翻牌,CI 收敛中」,然后没有人回来,卡挂了 10 小时),不指望运气。

pnpm lint 该轮完整跑了,未声明任何窄化;唯一声明的窄化是 check:type-check-debt --re-measure(需整仓构建,CI 拥有它),且用上面那个带反向对照的替代测量补上了。

翻牌 + 入队完成 —— CI 在 7544c02b5b 上收敛全绿

承接 5387612968(ACCEPT,当时两项未收敛)。这一轮回来做完了,自检未落空。

按 job 名读,34 项全部完成、零失败。上一轮悬着的两项均已转绿:Test Core (1/6) success(18:05:35)、Lint & Repo Gates success(18:03:55)。

5 项 skipped,如实记为「未运行」而非凑进绿灯数:Build Docs 与 Console Pin Gate 是路径过滤(本 diff 是单个测试文件);Auto Label/Check Changeset/Check PR Size 三项是被取代那次运行的重复条目 —— 同名 job 在本 PR 上各有一条真实的 success,按 job id 与运行 id 逐条比对确认,不是看名字重复就当过了。

⛔ 全程按 job 名读,未采用 rollup。

Clause-② no,复验而非继承(单个测试文件;pin、auth-manager.ts、两处脚手架抑制、packages/spec 全部未动)⇒ 无需契约复审档位,派发席权限之内:draft: false,自动合并已装(SQUASH),入合并队列。

本卡的目的已经达成,与合并无关

⭐ #11380 存在的理由是让 #3653 拿到一份真实的 diff。那份 diff 已于 3653#issuecomment-5387582046 贴出(逐字原文),#3653 已随之从 pm:blocked 移回 needs-user-decision,等待维护者裁定迁移路径。⇒ 那一步不依赖本 PR 合入,已经完成了。

落地后仍然成立的一条

⚠️ 这次修复对 CI 实际跑的版本零影响 —— 在钉住的 1.7.0-rc.1 上,修复前后都是 24 passed (24)。它改变的是**「pin 移动那一天会发生什么」**:届时门禁会打印模型差异清单,而不是一个不说明问题的 TypeError。

标准运维提示不变:SCIM 默认关闭,group 供给不通 —— 今天开启 SCIM 的部署不要让 IdP 推送 group,直到迁移落地。
