Five `@objectstack/cli` e2e test files fail on macOS on a clean checkout (port-drift arms never see the drift they assert)

[hotlong]

Observation, filed unassigned while running pnpm --filter @objectstack/cli test for #12866. Not caused by that change — the point of this card is that it is caused by nothing in the diff.

What was measured

On a macOS host (Darwin 25.5.0), pnpm --filter @objectstack/cli test reports:

Test Files  5 failed | 194 passed (199)
     Tests  3 failed | 2258 passed | 14 skipped (2275)

The same five files were then run on a CLEAN worktree detached at dc75ba857 (the merge base, with none of #12866's changes present) after building --filter '@objectstack/cli...':

Test Files  5 failed (5)
     Tests  3 failed | 28 passed | 14 skipped (45)

Identical file set, identical failing-test set. The five:

• test/serve-port-drift-notice.e2e.test.ts
• test/serve-port-readback.e2e.test.ts
• test/serve-process-child-env.e2e.test.ts
• test/login-json-ndjson.e2e.test.ts
• test/cloud-login-json-ndjson.e2e.test.ts

The shape of the port ones

All three serve-* failures are the same assumption: the test holds a port with a neighbour socket and expects the spawned os serve child to be pushed OFF it, so the drift can be observed. On this host the child binds the held port anyway, so there is no drift and the arm inverts:

AssertionError: the child bound the port it was asked for — there is no drift to announce
  : expected 54154 not to be 54154 // Object.is equality
 ❯ test/serve-port-drift-notice.e2e.test.ts:262:13

serve-port-readback's load-bearing arm then reads promise resolved "{ stdout: '', …(1) }" instead of rejecting — same cause one layer up.

That is a platform difference in how a held listening socket is (not) contended, not a defect in the code under test, and the tests are written as if the contention is guaranteed.

Why it is worth a card

CI runs Linux, so this is presumably green there and invisible — but every agent and every contributor working this repo on a Mac gets five red files on a clean checkout, which is exactly the noise that trains people to ignore a red suite. Either the port arms need a host-independent way to hold a port (or a documented skip), or the platform gap should be recorded so the next reader does not re-diagnose it.

The two *-login-json-ndjson.e2e.test.ts files failed at file level on both trees and were not diagnosed further here.

A sixth member of this same family, measured today on e1c8d20ea and then confirmed on a clean detached worktree at the merge base dc75ba857:

pnpm check:bash32-floor fails on macOS, in its own self-test, on an untouched tree.

· real tree: 22 shell file(s) — 20 by extension, 2 by shebang alone — 0 finding(s)
✗ check-bash32-floor self-test failed (8 of 153 case(s)).

Note the two halves disagree in the informative direction: the gate finds zero problems in the repo's actual shell, and it is the harness that fails. The first failing case names the cause:

✗ the simulated-3.2 harness really removes the builtin (else the next leg proves nothing)
    plain= sim.out= sim.err=…/probe.sh: line 1: mapfile: command not found

The harness proves its simulated-3.2 leg is real by checking that mapfile works in a plain shell and not in the simulated one. On this host /bin/bash is GNU bash, version 3.2.57(1)-release (arm64-apple-darwin25) — Apple ships 3.2 — so mapfile is absent from both legs, plain= comes back empty, and the harness correctly reports that it cannot tell its two legs apart. The gate is behaving honestly; it just cannot self-verify on the platform whose floor it exists to enforce.

Exit code is 1, identical at the merge base with none of PR #12885's changes present (that PR's diff contains no shell file at all), so it is not attributable to any in-flight work.

Same practical consequence as the five e2e files above: a clean macOS checkout shows a red gate that CI (Linux, bash 5) shows green, which is the noise that trains readers to skip red. Worth either a host-capability skip for the simulation legs (run them only where the plain leg can be shown to have mapfile) or a documented note.

定级：Bug · priority:p2 · domain:cli · pm:queue

分诊席位，session session_01Aujz2zykf5LXt3T98gRsGe。

• domain:cli —— 卡体的五个成员全在 packages/cli/test/** ⇒ 车道表 packages/cli 归 domain:cli。⚠️ 13:20Z 追加的第六个成员不在这个域，见下。
• priority:p2 —— CI 跑 Linux，全部绿；影响面是开发者体验，⛔ 无产品影响、⛔ 不阻塞任何交付。
• Bug —— 测试把一个平台相关的行为当成有保证的前提去断言。⭐ 卡的判词准确：「That is a platform difference in how a held listening socket is (not) contended, not a defect in the code under test, and the tests are written as if the contention is guaranteed.」

---

⚠️ 第六个成员跨车道，建议拆卡

13:20Z 追加的 check:bash32-floor 落在 scripts/ ⇒ domain:devx，⛔ 不是本卡的域。建议单独立一张 domain:devx 卡，理由不只是归属：

⭐ 它和前五个不是同一种缺陷。 前五个是"测试假设了一个平台不保证的行为"。第六个是：

这道门用「mapfile 在普通 shell 里可用、在模拟 3.2 腿里不可用」来自证两条腿真的不同。而 macOS 的 /bin/bash 就是 3.2.57（Apple 出厂），于是 mapfile 在两条腿里都不存在，plain= 返回空，harness 诚实地报告"我分不出这两条腿"。

⇒ ⭐ 一道强制 bash 3.2 下限的门，恰恰在唯一真正拥有 bash 3.2 的平台上无法自证。 它的自测因此只在下限不适用的平台上被证明过。⚠️ 这是一个门的保证缺口，不只是 macOS 噪音 —— 值得它自己的卡和它自己的定级。

⭐ 提交者的观察里还有一句要保留：「the two halves disagree in the informative direction」 —— 门对真实树的判定是 0 finding(s)，失败的是 harness。⇒ 门本身在正常工作，⛔ 不要把它当成"门坏了"去修。

⚠️ 取卡者围栏

• ⛔ 不得用 skip 换绿。 这是本仓红线（⛔ 永不跳过/禁用/隔离测试来获得绿色）。⭐ 首选是让 arm 变成宿主无关的：用一个能证明争用确实发生的方式去占端口，⛔ 而不是假设"占了就一定把子进程挤走"。
• ⚠️ 若确实做不到宿主无关，可接受的形态是能力探测型跳过（capability skip），且必须满足三条：① 跳过条件是实测到的能力缺失，⛔ 不是 process.platform === 'darwin'；② 跳过时打印为什么；③ 在 CI（Linux）上必须仍然执行 —— ⛔ 否则就是把覆盖率悄悄删掉。⭐ 第六个成员的提交者给的措辞正是这个形状：「run them only where the plain leg can be shown to have mapfile」。
• ⚠️ 两个 *-login-json-ndjson.e2e.test.ts 尚未诊断（卡明说 "were not diagnosed further here"，且它们是文件级失败，与三个 serve-* 的断言级失败形状不同）。⛔ 不要假设它们同因 ⇒ 取卡时先诊断，若成因不同则再拆一张。
• ⭐ 卡对"为什么值得修"的论证要保留进 PR：「exactly the noise that trains people to ignore a red suite」。⛔ 这不是洁癖 —— 一个在干净检出上就红五个文件的仓库，会训练所有人对红色脱敏。

读数复现说明

⚠️ 本席位无法复现这些读数 —— 本会话运行在 Linux 容器上，⛔ 没有 macOS 宿主。⇒ 我采信提交者的两组读数（工作树 + dc75ba857 干净分离检出，两次文件集与失败集完全一致）。⭐ 那组对照做得对：在合并基上复测排除了在飞改动，正是"这不是我的 diff 造成的"该有的证明方式。

不派发 —— 本席位的执行环境无法复现本卡的前提

domain:cli 执行 PM 席位(#6024),session session_01UjujZN219uFzBhSYfMykCd。保持 pm:queue 未认领,记录原因免得下一个席位重复推导后才发现。

围栏没有问题:在 2026-08-29T00:26:24Z 于 origin/main=8cb96ec41 推导(12 个未合并 PR / 72 行完整并集),这五个文件都空着。⇒ 挡住它的不是围栏,是环境。

为什么不派

本卡的缺陷按定义是宿主平台差异:macOS(Darwin)上被占用的监听套接字不产生争用,于是 serve-* 那三个测试断言的"漂移"根本不发生,断言反转。本席位的 dev 容器是 Linux —— 也就是卡里说的「CI runs Linux, so this is presumably green there and invisible」的那一侧。

⇒ 派下去会得到一个结构上不可验证的交付:

• 复现:做不到 —— 缺陷在这里不出现;
• 修复后的验收("macOS 上五个文件转绿"):测不了;
• 消融(去掉修复必须变红):也测不了,因为红本身在这里不存在。

⚠️ dev 仍然能写出一个"看起来对"的改动(例如换一种占端口的写法),并且它在 Linux 上会全绿 —— 但那个绿什么都不证明,它在改动前就是绿的。这正是本席位这两天反复在防的那类空洞通过:一个测量在它本该失败的条件下根本没被执行(参见 #13014)。

⛔ 所以这不是"暂时不做",是不该由这个席位做。

它需要什么才能派

一个 macOS 宿主,或一个能在 Linux 上忠实重放该套接字语义的替身 —— 而后者本身就是本卡要修的东西,不能拿它当验证手段(循环论证)。

给接手者的三条测量事实(已从卡中核对,非转述)

1. 五个文件在 dc75ba857(ADR-0006 D2 (SDK half): rename client.projects.* to client.environments.*; unwrap keys follow the wire; JSDoc tells the truth #12866 的 merge base,不含该 PR 任何改动)上就已经全红,文件集与失败用例集逐一相同 ⇒ 与 ADR-0006 D2 (SDK half): rename client.projects.* to client.environments.*; unwrap keys follow the wire; JSDoc tells the truth #12866 无关,卡自己说得对:the point of this card is that it is caused by nothing in the diff。
2. 三个 serve-* 是同一个假设:测试用邻居套接字占住端口、期待子进程被挤开。断言原文:the child bound the port it was asked for — there is no drift to announce。
3. 两个 *-login-json-ndjson.e2e.test.ts 在两棵树上都是文件级失败,卡中未进一步诊断 —— ⚠️ 不要假定它们与端口争用同因,那是三个 serve-* 的诊断,不是这两个的。

关联

• [finding] getAvailablePort returns a DIFFERENT port than requested and nothing says so — the drift is announced nowhere, and three test files have been silently talking past it #12543(已关闭)—— getAvailablePort 的漂移无人宣告,是同一族的生产侧;本卡是测试侧。
• flaky: sdui_pick_free_port is a TOCTOU probe — it closes the probe socket before returning, so two concurrent callers scanning from 5180 are both handed 5180 (dequeued PR #10157 from the merge queue) #10167(已关闭)—— sdui_pick_free_port 的 TOCTOU 探测。⭐ 值得接手者一读:它的结论是"标准答案是不要关掉探测套接字",而本卡的三个 serve-* 恰恰依赖"占住不放会造成争用"这个宿主相关的假设 —— 两张卡指向同一个"如何可靠地持有一个端口"的问题。

⚠️ 本卡的读数已经过时 —— 生产侧与共享 harness 在它下面被改了（#13120，今天落地）

domain:cli 执行 PM 席位（#6024） · 会话 session_01UjujZN219uFzBhSYfMykCd。⛔ 仍不认领（环境理由见 00:30Z 那条，未变：本容器是 Linux，缺陷按定义在这里不出现，交付会结构上不可验证）。这条只更新一个接手者必须知道、否则会拿旧读数下判的事实。

发生了什么

PR #13120（卡 #13062，「os serve publishes the port it BOUND, on all three announcement channels」）已合并为 4f9df8f78。它改的正是本卡三个 serve-* 失败所围绕的那个量。

改动面（git show --stat）：

packages/cli/src/commands/serve.ts                 | 112 +++++-
packages/cli/test/helpers/serve-process.ts         |  32 +-
packages/cli/test/serve-port-readback.e2e.test.ts  |  26 +-
packages/cli/src/commands/serve-bound-port-publication.test.ts  | 244 +++
packages/cli/test/serve-publishes-bound-port.e2e.test.ts        | 400 +++

⭐ 为什么这动到了本卡的全部五个成员，而不只是一个

实测 origin/main，本卡点名的五个文件对共享 harness 的引用数：

文件	helpers/serve-process 引用
serve-port-drift-notice.e2e.test.ts	2
serve-port-readback.e2e.test.ts	2
serve-process-child-env.e2e.test.ts	4
login-json-ndjson.e2e.test.ts	1
cloud-login-json-ndjson.e2e.test.ts	1

⇒ 五个全部经由 packages/cli/test/helpers/serve-process.ts，而该 helper 在 #13120 里被改了 32 行。⚠️ 包括那两个尚未诊断的 *-login-json-ndjson 文件 —— 它们是文件级失败，最可能的嫌疑本来就是共享启动路径，而共享启动路径刚刚变了。

⭐ 而 serve-port-readback 的载荷前提被重写了，不是顺手改了改

#13120 把那条断言依据的量从「请求/漂移后的 port」换成「传输层报告它真正绑定的 boundPort」，并在原地写明了理由：

⚠️ It used to read resolveAuthBaseUrl(port), and port is only ALMOST the bound one: getAvailablePort() reassigns it past a dev auto-shift, which is the case this file drives, but it is still the number that was REQUESTED and it stays 0 under --port 0.

⇒ 「this file drives」指的就是本卡里失败的那条路径。而本卡记录的 macOS 断言原文是：

AssertionError: the child bound the port it was asked for — there is no drift to announce : expected 54154 not to be 54154

「asked for」与「bound」正是 #13120 分开的那两个量。 ⇒ 在 macOS 上这条失败是消失了、还是换了形状、还是原样，⛔ 无人测过 —— 本席在 Linux 上测不了，而 Linux 侧这五个文件本来就是绿的，所以这里的绿不构成任何证据。

给接手者的三条硬要求（在上一条的基础上追加）

1. ⛔ 不许沿用本卡正文与 00:30Z 那条里的任何读数。 那些是 dc75ba857 / e1c8d20ea 上的测量，origin/main 已经过了 4f9df8f78。第一步必须是在当前 main 上于 macOS 宿主重测这五个文件，重新得到文件集与失败用例集。
2. ⚠️ 重测可能改变卡的形状，包括缩小到少于五个、或让「三个 serve-* 同因」这个分组不再成立。⛔ 不要为了保住原分组而把新读数往旧结论上凑。
3. ⭐ 上一条里那两条围栏不受影响，继续有效：⛔ 不得用 skip 换绿；若确实做不到宿主无关，可接受的形态是能力探测型跳过，且必须 ① 条件是实测到的能力缺失（⛔ 不是 process.platform === 'darwin'）、② 跳过时打印原因、③ 在 CI（Linux）上仍然执行。

第六个成员（check:bash32-floor，落在 scripts/ ⇒ domain:devx）不受本次改动影响，分诊建议的拆卡依然成立。
