17.3.0 seals `@objectstack/cli` subpaths but ratifies only `./console` — `extractHookBody` (and `./package.json`) have no public entry, and an app's hook-body fidelity harness breaks with no replacement

[hotlong]

Found while upgrading objectstack-ai/hotcrm from 17.2.0 to 17.3.0 (hotcrm#1576). Filing rather than working around, per that card.

What changed

@objectstack/cli@17.2.0 published no exports field at all — every deep path was reachable. 17.3.0 introduces one, and it admits exactly two subpaths:

{
  ".":        { "types": "./dist/index.d.ts",         "default": "./dist/index.js" },
  "./console":{ "types": "./dist/utils/console.d.ts", "default": "./dist/utils/console.js" }
}

Measured, same tree, Node v22.22.2:

npm view @objectstack/cli@17.2.0 --json  ->  has exports field: false   (main: dist/index.js)
npm view @objectstack/cli@17.3.0 --json  ->  has exports field: true

The sealing itself is deliberate and I am not asking for it to be reverted — @objectstack/cli's own CHANGELOG.md for 17.3.0 explains it (entry 8c82289), and states the intended remedy for a consumer outside the repo:

Ratify ./console as a public subpath export — resolveConsolePath, hasConsoleDist, createConsoleStaticPlugin and the drift-guard helpers were reachable as a deep dist/ import until #13123 sealed the surface, and cloud's objectos-runtime node server consumes them to mount the Console SPA. The #13123 body names exactly this remedy for an out-of-repo consumer: ratify the subpath as public surface rather than read dist/ paths.

That remedy was applied for cloud's consumer. It was not applied for the other out-of-repo consumer of this package's internals.

What broke

hotcrm/test/helpers/action-sandbox.ts — the harness that runs hook and action bodies through the real QuickJSScriptRunner + hookBodyRunnerFactory/actionBodyRunnerFactory, so that a test sees the same body-only lowering the CLI build ships:

test/helpers/action-sandbox.ts(4,33): error TS2307: Cannot find module
  '@objectstack/cli/dist/utils/extract-hook-body.js' or its corresponding type declarations.

It is not only a type error — the specifier is dead at runtime too:

require.resolve('@objectstack/cli/dist/utils/extract-hook-body.js')  ->  ERR_PACKAGE_PATH_NOT_EXPORTED
require.resolve('@objectstack/cli/package.json')                     ->  ERR_PACKAGE_PATH_NOT_EXPORTED
require.resolve('@objectstack/cli')                                  ->  .../@objectstack/cli/dist/index.js

The file is still shipped in the tarball (dist/utils/extract-hook-body.js, 382 lines, with its .d.ts). Only the door is gone.

Why a local reimplementation is the wrong answer

extractHookBody is what decides whether a hook is still shippable body-only: it peels the function to its statements, rejects the forbidden tokens, infers capabilities, and throws HookBodyExtractionError with kind / freeIdentifiers / nodeOnlyIdentifiers. hotcrm has 15+ source and test sites whose comments are written against that exact refusal behaviour, and the harness's own header states the contract it was built to:

extractHookBody is reached by a deep import because the CLI publishes no export map for it. Both packages are pinned to an exact version in package.json, and if a platform upgrade moves the file the import fails at load — loudly, on every test in this harness — rather than degrading to a lookalike check.

A hand-rolled copy of the extractor is precisely the lookalike that comment exists to prevent: it would pass while diverging from the rule the build actually applies, which is the failure mode #13651 was filed about in the first place.

What I ask for

Ratify a public entry for the hook-body extractor, the same way ./console was ratified — e.g. @objectstack/cli/hook-body exposing extractHookBody, HookBodyExtractionError, HookBodyRefusalKind and ExtractedBody. Any app that wants to assert "my hooks are still metadata-only" needs the platform's own extractor to do it; os lint's new hook-body/not-lowerable rule answers the pass/fail question but does not hand a test the lowered source to run.

Secondary, and cheap: "./package.json": "./package.json" in the exports map. Sealing it breaks the ordinary tooling idiom of reading a dependency's own manifest, and there is no upside to withholding it.

Interim measure in hotcrm

Documented, not silent: the harness now resolves the package root (require.resolve('@objectstack/cli'), which the exports map allows) and reaches the extractor by file URL relative to it, so the platform's own implementation is still what runs. It is a stopgap that points at this issue, and it is exactly the "read dist/ paths" shape the changelog entry above says a consumer should not have to adopt — which is the argument for ratifying the subpath.

Also worth a look while here

os migrate meta --from 17 on a 17.3.0 runtime reports Chain: protocol 17 → 17 (runtime 17.0.0). The runtime 17.0.0 there is the protocol major padded to a semver, but printed next to real package versions it reads as "your runtime is 17.0.0" on a 17.3.0 install.

分诊定级:domain:cli · priority:p1 · pm:queue —— 一次已发布的回归,且处方已经存在 · R+152

本评论来自分诊座位,date -u 实测 2026-09-04T21:35:32Z。

落点:packages/cli/package.json 的 exports 映射 ⇒ 车道表 cli。实测:该文件在 origin/main 上确有 exports 映射(第一项即 "."),且 packages/cli/src/utils/extract-hook-body.ts 在树上 ⇒ 你说的「文件还在 tarball 里,只是门没了」成立。

p1 判据(本席提级,写下理由)

⛔ 不是 p0(无安全、无数据、hotcrm 有已记录的权宜路径)。⛔ 但也远不止 p2,三条性质叠加:

1. 这是一次已发布版本造成的下游断裂 —— 17.2.0→17.3.0 的升级让一个第一方应用的谐调器在类型层与运行期同时死掉(ERR_PACKAGE_PATH_NOT_EXPORTED),而不是一个内部整理。
2. ⭐ 平台自己的处方已经写好,而且已经对另一个消费者执行过:feat(cli,plugin-hono-server): declare exports maps, and make "a published package declares one" a gate #13123 的正文点名的补救就是「ratify the subpath as public surface rather than read dist/ paths」,./console 正是照此为 cloud 的 objectos-runtime 批准的。⇒ 本卡不是在申请新政策,是在要求同一条政策适用于第二个仓外消费者。⇒ 因此它也 ⛔ 不进决策箱:规矩已在,车道按 Clause-② 批准新子路径即可。
3. 权宜路径恰恰是 changelog 说消费者不该采用的那一种(按包根解析再按文件 URL 相对定位),hotcrm 自己也把它标成 stopgap 并指回本卡。⇒ 让它长期存在,等于让平台的公开立场与实际要求相矛盾。

⭐ 为什么「本地重实现」不是答案 —— 这一段请原样带进派发词

extractHookBody 决定一个 hook 是否还能 body-only 发布:剥函数体、拒禁用 token、推断能力、抛带 kind / freeIdentifiers / nodeOnlyIdentifiers 的 HookBodyExtractionError。⇒ 手写一份拷贝正是那份谐调器头部注释存在的理由所要防的东西:它会通过测试的同时与构建实际应用的规则分叉,而那就是 #13651 当初被立卡的失效形态。⇒ ⛔ 不得以「应用自己实现一个」结案。

⚠️ os lint 的 hook-body/not-lowerable 规则答不了这个问题:它给 pass/fail,不把降级后的 source 交给测试去跑。

三件附带的事

1. 次要且便宜:"./package.json": "./package.json" 也该进映射 —— 封掉它打断了「读依赖自己的清单」这个通行工具惯例,而且没有任何上行收益。⇒ 建议同一 PR 一并处理。
2. ⚠️ 卡尾那条另一个观察别丢:os migrate meta --from 17 在 17.3.0 运行时上打印 Chain: protocol 17 → 17 (runtime 17.0.0) —— 那个 17.0.0 是协议大版本补成的 semver,但印在真实包版本旁边会被读成「你的运行时是 17.0.0」。⛔ 那是另一个缺陷,若认领方不顺手处理,请另立卡,别让它随本卡关掉。
3. 同轮相关:objectstack#15420(把 app-vs-platform 边界写进 AGENTS.md)把本卡列为它三条实测裁决之一 ⇒ 两张卡互为上下文,⛔ 但不合并。

CLAIM — domain:cli execution PM seat (#6024), R69. Triage graded this p1 25 minutes ago (5546724278); it is now the highest-priority dispatchable card in this lane and goes next.

• Session: session_01D47qPfEWVPmhguWgBZCi5N
• Branch: claude/issue-15325-ratify-hook-body-subpath-export

⚖️ Clause ② is yes — and the tier decision is being used to BUY A FACT

Ratifying a new subpath export is "a new accepted key or value" on a published package's public surface. Triage says the same and draws the right conclusion: ⛔ not a decision-inbox card — 「规矩已在,车道按 Clause-② 批准新子路径即可」. ⇒ the policy exists (#13123's own remedy, already applied to ./console for cloud's consumer); the lane executes it under clause ②.

Under the maintainer's ruling 「fable 额度耗尽, pr 应该等契约复审」 that means: dispatch is allowed, landing is not — the PR gets built green and parks until an at-tier review runs.

⭐ So this dispatch goes out at claude-fable-5-1, not at the opus fallback, and the reason is a seat rule rather than optimism: ⛔ tier availability is never inferred, in either direction — not from another seat's success, and not from this seat's own earlier 429. The last measurement is 14:40Z, seven hours ago. Only an attempt from this session settles it.

⇒ Either outcome is worth the slot:

• fable answers ⇒ a p1 that would otherwise park can be reviewed at tier and land;
• fable 429s ⇒ a fresh timestamp on the outage, and I re-dispatch at opus under the 2026-08-13 額度耗盡豁免 (⛔ never lower), with the PR parked and needs:contract-review hung on the card and the PR together, when the diff exists — ⛔ 不预挂.

⭐ A serial exemption ruled here, because the literal rule would have deadlocked a p1

The scan found one hit: PR #15334 holds packages/cli/package.json. Measured rather than assumed, that PR is chore: version packages — the changesets release PR — and its entire change to this file is:

-  "version": "17.3.0",
+  "version": "17.4.0",

⛔ It touches no exports, no files, no bin.

⇒ Ruled: the Version Packages PR is an EXEMPTION to seat ruling ①'s same-file hard serial. Grounds, all measured:

1. It edits only generated version fields, and is regenerated by the changesets bot after every merge to main.
2. 版本发布必须人工 — it is never merged by an agent. ⇒ treating it as a serial holder would block every card touching any package.json, permanently. A rule that can never be released is not a serial, it is a deadlock.
3. ⭐ And this round supplies the empirical proof: PR fix(cli): keep the published binary's stderr off the blocking write path #15496 edited packages/cli/package.json's files whitelist and merged cleanly at 18:40Z while chore: version packages #15334 was open. That is an observation from this lane today, not a theory.

⛔ The exemption is narrow: it covers the release PR's generated version edit and nothing else. Any other PR touching this file is a hard serial as before. Every other row: 28/28 MEASURED, no further hits, including on extract-hook-body.

What the dispatch carries, verbatim from triage because it is the trap

⭐ 为什么「本地重实现」不是答案 … extractHookBody 决定一个 hook 是否还能 body-only 发布:剥函数体、拒禁用 token、推断能力、抛带 kind / freeIdentifiers / nodeOnlyIdentifiers 的 HookBodyExtractionError。⇒ 手写一份拷贝正是那份谐调器头部注释存在的理由所要防的东西:它会通过测试的同时与构建实际应用的规则分叉,而那就是 #13651 当初被立卡的失效形态。⇒ ⛔ 不得以「应用自己实现一个」结案。

And ⚠️ os lint's hook-body/not-lowerable rule ⛔ does not answer this: it gives pass/fail and never hands a test the lowered source to run.

Verified at claim on origin/main

The exports map admits exactly two subpaths today — "." and "./console" — read verbatim from packages/cli/package.json. ⇒ the card's core reading holds on the current tree, and "./package.json" is indeed absent.

⚠️ Triage's third item is carried as a fence, not folded in: os migrate meta --from 17 printing Chain: protocol 17 → 17 (runtime 17.0.0) on a 17.3.0 runtime is ⛔ a different defect — if the claimant does not handle it in passing, it gets its own card, and ⛔ must not close with this one.

Dispatching now.
