finding(app-shell): fetchFullPackage never reads res.ok, so a failed package lookup opens the management sheet on a null package - silently

[claude]

Observation

Found while fixing objectui#7821 (the onManageChanged false-deletion eviction), in the
same component and one callback above it. Deliberately not fixed there: that card is
scoped to the deletion inference, and this is a different swallowed failure with a
different wrong outcome.

fetchFullPackage in packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx
(origin/main 384715bb1, the PackageSwitcher helper that backs openManage):

const fetchFullPackage = React.useCallback(async (id: string) => {
  const res = await fetch('/api/v1/packages', {
    credentials: 'include',
    headers: { Accept: 'application/json' },
    cache: 'no-store',
  });
  const data = (await res.json()) as unknown;
  const root = (data as { data?: unknown })?.data ?? data;
  const list = (Array.isArray(root) ? root : ((root as { packages?: unknown[] })?.packages ?? [])) as ...;
  return list.find((p) => (p?.manifest?.id ?? p?.id) === id) ?? null;
}, []);

res.ok is never read. The endpoint answers an error the way the rest of this platform
does — a JSON envelope with success: false and an error object — so on a 4xx/5xx
that envelope parses cleanly: root is the error object, it is not an array and has
no packages, so list is [] and the function returns null. Nothing throws, so
openManage's catch (which does toast, formatMetadataError) never runs:

setManage(await fetchFullPackage(id));   // null
setManageOpen(true);                     // …and the sheet opens anyway

Net effect: an author clicking "Package info & settings" during an outage gets the
management sheet opened on a null package — no toast, no error, no explanation —
instead of being told the lookup failed. Same defect family as objectui#7368 and
objectui#7821, third variant: not a lost toast and not an inverted decision, but a
failure laundered into a successful-looking empty result.

Two adjacent observations on the same function, offered as context rather than as
separate claims:

• It reaches /api/v1/packages with a raw fetch, which AGENTS.md §7 bans in
  components in favour of @objectstack/client; the sibling fetchPackages in
  ./packages-io.ts already goes through the sanctioned path and already owns the
  two-shape envelope parsing this function re-implements by hand.
• It is a fourth call to the same endpoint on this surface (the switcher list, the
  writability courtesy gate and the namespace lookup are the other three, per
  objectui#7368).

Worth deciding

1. Check res.ok (and the success: false envelope) and throw, so openManage's
   existing catch reports it on this file's shared studio-package-list sonner id and
   the sheet does not open. Cheapest, and reuses the posture that already exists here.
2. Do not open the sheet on a null result regardless of how the null arose — a
   guard at the call site rather than at the fetch.
3. Retire the hand-rolled fetch in favour of the packages-io reader plus a
   full-record variant, which would make 1 and the two adjacent observations one change.

Not obviously the same call as objectui#7368's (that one deliberately DEGRADES because
the top bar must survive a 503); here the affordance is a modal the author explicitly
asked for, so refusing to open it is a live option.

Re-check

grep -n "fetchFullPackage" -A 14 packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx

Related, not duplicates: objectui#7368 (the switcher's silence, merged), objectui#7821
(the false-deletion eviction, this file, in review), objectui#7373 (where a recovery
redirect should land).

• Worktree: /home/user/objectui-issue-7881
• Domain: domain:ui

• Container & model: 本会话容器 · opus
• Clause-②: no
• Serial constraints cleared: ⚠️ PR fix(app-shell): a failed package-list refresh is not a deletion (objectui#7821) #7879 已于 01:47:44Z 落地，改的正是同一文件的 onManageChanged —— 你从 origin/main 起分支即带上它，并且它是本卡的直接样板。当前 11 个 open PR 无一触碰该文件。

这是 #7368 家族的第三个变种，而且样板刚刚落地

#7879（卡 #7821，已落地）就是本卡的工作样板，请先读它的 diff 与落地记录。它确立的原则一字不改地适用：

空数组是一个完全合法的成功答案，所以任何拿 [] 当失败初值的写法，都在用一个合法的成功值表示失败。

本卡是同一个病的另一处：fetchFullPackage 从不读 res.ok ⇒ 一个返回平台 success: false JSON 信封的 4xx/5xx 能干净地解析、产出空列表、返回 null 而不抛 ⇒ openManage 的 catch 永远不运行 ⇒ 管理面板静默地开在一个 null 包上。

交付物

1. 读 res.ok（以及平台信封自己的 success 字段，若它在这条路径上可判 —— 先量，再决定读哪个或两个都读）；
2. 失败走本文件已有的 app-shell(studio): PackageSwitcher swallows the package-list fetch failure, leaving the raw package id in the top bar #7368 姿态 —— formatMetadataError + 共享 sonner id + 既有的错误槽，与 fix(app-shell): a failed package-list refresh is not a deletion (objectui#7821) #7879 落地的那套同一套。⛔ 不要开第二台错误状态机：修「错误被吞掉」时最容易顺手引入第二套上报机制，然后两套各自漂移。fix(app-shell): a failed package-list refresh is not a deletion (objectui#7821) #7879 明确避开了这一点。
3. 管理面板不得开在一个 null 包上 —— 这是本卡的用户可见交付。

⛔ 证据形状：照 #7879 的消融做，而且要证明「新钉子不是在复述旧钉子」

#7879 的消融之所以有说服力，是因为撤掉修复后钉子 1、2 红而钉子 3、4、5 保持绿 —— ⭐ 最后半句才证明了新钉子不是在换个说法重复既有断言。

本卡照做：

• 改前：构造一个返回 success: false 信封的 4xx/5xx，证明 fetchFullPackage 返回 null 且不抛、openManage 的 catch 没运行、面板开了；
• 改后：同一输入下面板不开，且错误经既有通道被报出；
• 阴性对照：一次真正成功的 fetchFullPackage，改前改后都正常开面板 —— ⛔ 否则你可能只是把面板关死了。
• 突变先在磁盘上证明落盘（锚计数 + blob hash），恢复由状态证明（git diff HEAD 空 + blob 回到 HEAD），⛔ 不用退出码证明恢复。

⚠️ 一件必须先量的事

res.ok 为 false 时，平台到底返回什么？卡面说的是「返回平台 success: false JSON 信封」。⛔ 不要假设：去量这条路径上真实的响应形状（HTTP 状态码、body 结构、有没有 error/message 字段），因为 formatMetadataError 要吃到有意义的东西才能报出有意义的话。⚠️ 若发现响应形状不止一种，如实报出全部形状并说明你的处理覆盖了哪几种、漏了哪几种。

边界

• ⛔ /home 硬编码不是本卡的 —— 归 finding(app-shell): app-missing / access-denied 恢复重定向仍写死 /home，应跟随声明的落地页（#7256 裁 B 的后续，先量夹具改动） #7373。fix(app-shell): a failed package-list refresh is not a deletion (objectui#7821) #7879 逐字节保留了它，你也保留。
• ⛔ 不动 onManageChanged（fix(app-shell): a failed package-list refresh is not a deletion (objectui#7821) #7879 刚修完）。
• changeset： app-shell 是已发布包且改 src/ ⇒ 机械地欠一份，且这是真实用户可见修复 ⇒ 大概率 patch。⛔ 不要用我这句猜测：跑 node scripts/check-changeset-presence.mjs，以判词为准并逐字贴出。
• Clause-② = no：不加导出、不改签名、不动任何 gate。若判断错了，停下报回。

"pr": "#7906",
"premise_still_valid": true,
"summary": "Premise confirmed on origin/main d9580f4: fetchFullPackage went straight to res.json() and never read res.ok, so a platform error envelope parsed cleanly into an empty list, returned null without throwing, openManage's catch never ran, and setManageOpen(true) still fired over a null package (PackageDetailSheet renders null for a null pkg, so the click did nothing and said nothing, leaving manageOpen stuck true). Fix: (1) res.ok is read and a non-2xx throws carrying the server's own error.message plus error.code, falling back to 'HTTP nnn' when the body is not the envelope; (2) reported through this file's EXISTING #7368 posture only - formatMetadataError on the shared studio-package-list sonner id, no second channel, no new slot; (3) the sheet no longer opens on a null package at all, and a successful list that simply lacks the package says so through the same channel. MEASURED RESPONSE SHAPES, as asked: GET /api/v1/packages is served by the direct-mount registrar (mounts FIRST in production, pinned by check:route-envelope at zero hand-written bodies), so every failure leaves through the shared sendError / sendThrownError as ONE shape - success:false with error:{code,message} - reachable as 401 UNAUTHENTICATED, 403 FORBIDDEN (studio.access / setup.access capability gate), 503 SERVICE_UNAVAILABLE (either half of the two-source merge) and 500 INTERNAL_ERROR; pinned wire-side by package-envelope.conformance.test.ts. The envelope's own success is therefore NOT a second decidable bit here (sendOk writes true on every 2xx, the error writers false on every non-2xx - it is !res.ok restated), so res.ok is the decision and the envelope is read for the WORDS; in the 5xx band the platform withholds the producer's prose for the generic INTERNAL_ERROR_MESSAGE 'Internal server error', leaving error.code as the only discriminating word, which is why the code travels with the message. A SECOND shape exists and is covered: a non-JSON error body (a proxy's HTML 502/504), where res.json() rejects - the one arm the pre-fix code did reach the catch on, showing the author a JSON syntax error; the tolerant read now names the status. No third shape found on this path. BOUNDARIES: the /home hard-coding is byte-for-byte untouched (#7373), onManageChanged is byte-for-byte untouched (#7879), the hand-rolled fetch is deliberately kept (card option 3; it cannot reuse fetchPackages because parsePackages trims the full record this sheet needs). Clause-2 holds: no export added, no signature changed, no gate touched. ONE DELIBERATE DEVIATION from the dispatch, flagged in open_questions and in the PR body: the failure is NOT also recorded in pkgsErr. Measured in-file rule - pkgsErr is written exactly where pkgs is (the mount effect and onManageChanged), and the two sibling fetchPackages call sites that do not write the list (the writability courtesy gate, the namespace lookup) report through the shared toast id with no slot write. openManage never writes pkgs, so marking the trigger 'failed' would claim the on-screen names moved when they did not.",
"tests": "All runs on the pushed commit c2c0f04 with git diff HEAD empty; exit codes captured by redirecting first (cmd > log 2>&1; EXIT=$?), never through a pipe; heavy runs serialized through the container's shared verify lock (scripts/pm/os-verify-lock.sh, slot issue-7881) and read from its VERDICT line. DEPENDENCY CLOSURE BUILT FIRST (the TS2307 stale-dist trap): pnpm --filter '@object-ui/app-shell^...' build VERDICT command-exit 0. NOTE - one false-green averted: pnpm --filter @object-ui/app-shell exec vitest ... was REFUSED by the repo's own vitest-invocation guard (objectui#3378: running vitest from a package dir silently runs apps/console's 22 files and reports 'Test Files 22 passed'). Re-run correctly from the repo root. TARGETED: pnpm exec vitest run --maxWorkers=2 over the 9 new pins + objectui#7821's 5 + objectui#7368's 7 => 'Test Files 3 passed (3)' / 'Tests 21 passed (21)', EXIT=0. WIDER: whole studio-design directory => 'Test Files 50 passed (50)' / 'Tests 271 passed (271)', EXIT=0. All 16 metadata-admin suites that read the edited i18n table => 'Test Files 16 passed (16)' / 'Tests 136 passed (136)', EXIT=0. TYPE-CHECK: pnpm --filter @object-ui/app-shell run type-check EXIT=0, with the script name echoed ('> @object-ui/app-shell@17.6.0 type-check') so this is not the zero-match silent pass. Proved NOT vacuous: tsc -p tsconfig.test.json --listFiles lists all three edited/added files, 1 hit each. ABLATION (the fix reverted to origin/main d9580f4, the new pins kept). MUTATION PROVED ON DISK BEFORE ANY READING: HEAD blob deba94ef vs on-disk 781e0c89 (differ, non-empty), anchors flipped if (!res.ok) 2->1, setManage(await fetchFullPackage(id)); 0->1, manageMissing 1->0. NO REBUILD LEG APPLIES and this is stated rather than skipped: the pins import './StudioDesignSurface' by RELATIVE specifier, so vitest transforms the .tsx source directly and no dist/ stands between the mutation and the run. Result: 'Tests 6 failed | 8 passed (14)'. The 6 reds are exactly the new claims (503 no-sheet, 503 reported, 403, 401, non-JSON 502, successful-but-absent); the 8 greens are the 3 negative controls plus all 5 of objectui#7821's pins. THAT LAST CLAUSE IS THE POINT: the negative controls stay green with the fix reverted, which proves the new pins are not restating an existing assertion and that a 'fix' merely closing the sheet could not pass this file. The reds ARE the defect, verbatim from the log: data-managed-id="" on four of them (the sheet opened on a null package); 'AssertionError: expected "vi.fn()" to be called at least once' (openManage's catch never ran, nothing reported); and the non-JSON arm answering a SyntaxError naming the opening angle bracket of the proxy's HTML page instead of 'HTTP 502'. RESTORE PROVED BY STATE, NOT BY AN EXIT CODE: on-disk blob back to deba94ef = the HEAD blob, git diff HEAD --name-only empty, anchors back to 2/0/1. The script carried trap ... EXIT INT TERM restoring an ABSOLUTE path (REPO_ROOT from git rev-parse --show-toplevel) and the restore named HEAD explicitly, since a bare git checkout -- path restores from the index that git checkout ref -- path had just written with the mutation. GATES (derived from the actual diff - a .tsx source, the app-shell i18n table, a new .test.tsx, a .changeset/.md - not only from the dispatch's list): check:governed-queue-guard --test over the 4 changed paths => 'NOT GOVERNED - 4 path(s) checked against 5 governed surface(s); none matched.'; its --self-test => 'OK check-governed-queue-guard self-test: 132 cases pass'. check-changeset-presence.mjs => '2 source file(s) of 1 released package(s) changed, and this change declares 1 changeset(s)' (its first verdict, before the changeset, was the refusal quoted in the PR - the patch level follows its own 'minor at most, never major' rule). check:i18n-keys, check:i18n-drift, check:i18n-dead-keys, check:vi-mock-specifiers, check:vi-mock-inherit all EXIT=0; check:control-bytes => 'check-control-bytes: OK (scanned 6393 tracked text file(s); skipped 85 binary).' Derived beyond the dispatch's list and run: the three i18n gates and both vi-mock gates. Confirmed OUT of scope by measurement: packages/i18n's all-locales-key-parity, which covers the ten locale packs - the app-shell table I edited is not one of them (stated in packages/i18n/src/tests/appDesigner-fieldDesigner-formula-retired-6310.test.ts). LINT - A DECLARED AND MEASURED NARROWING, not a skip, with all three pieces of evidence: (1) population read from eslint itself, eslint . over the whole affected package linted 1079 files, 0 errors; (2) the count comes from --format json, not from a guess; (3) config invariance for untouched files - eslint.config.js extends tseslint.configs.recommended with languageOptions {ecmaVersion, globals} and declares NO parserOptions.project and no projectService, so type-aware linting is not enabled and every rule's verdict is a function of that file's own text plus the shared config; a diff confined to three files cannot move any untouched file's verdict. The 3 changed files alone: 0 errors; the 19 warnings on StudioDesignSurface.tsx are all pre-existing (lines 691-4211, while every line this PR adds is in 363-460). The repo-wide turbo lint run is CI's. NOT RUN and owed to CI: the remaining ~600 app-shell test files (625 total; at the measured 3.1s/file under contention that exceeds the container's ~10min foreground cap). The i18n edit is provably purely additive - git diff --numstat reads '5 0' and zero lines match '^-[^-]' - so no existing key's value moved.",
"mcp_calls": "0 - every GitHub read and write went through repo-scoped REST with $GITHUB_TOKEN (all 200/201); /search/ was not used at all, the de-dup instead paged the open-issue listing to exhaustion (5 pages, 400 issues with PRs excluded) with #7881 itself as the known-hit control, then grepped locally",
"open_questions": [
{
"question": "The dispatch named the existing error SLOT (pkgsErr) as part of the #7368 posture to reuse. I report the failure on the shared studio-package-list sonner id but deliberately do NOT write pkgsErr. Is that the posture you intended?",
"options": [
"A - as landed: shared toast id only. pkgsErr is written exactly where pkgs is (the mount effect and onManageChanged); openManage never writes pkgs, so the trigger's names are as current as they were a moment ago, and the two sibling fetchPackages call sites that do not write the list report the same way.",
"B - also setPkgsErr(message) in openManage's catch, extending #7879's 'a failure wins over a list already in hand' from a failed REFRESH to any failed read of that endpoint, on the argument that a failing endpoint means the on-screen list can no longer be confirmed current."
],
"recommendation": "A, because it is the measured in-file rule rather than my judgment: pkgsErr and pkgs are written as a pair at both existing sites, and its own doc calls it 'the last package-list failure' driving the trigger's read of the list it is showing. B is a one-line change if you disagree - say so and I will push it."

"out_of_scope_findings": [
"filed as #7907: onManageChanged's TAIL (the managed-snapshot refresh, distinct from the head #7879 repaired) swallows a failed fetchFullPackage silently, so after a lifecycle action the open sheet presents the pre-action record as current - and this card widened that arm, since before it that catch could only see a res.json() rejection and now it also sees every 401/403/503/500. No assignee, no labels, left for PM triage. De-duped against the exhausted 400-issue open population."

PM 裁定 · PR #7906 · 开放问 = A · 外加两条关于工具本身的发现

裁定：A（只走共享 toast id，⛔ 不写 pkgsErr）

采纳，而且理由是实测的文件内规则而不是判断：

• pkgsErr 恰恰写在 pkgs 被写的地方（挂载 effect 与 onManageChanged）；
• openManage 从不写 pkgs；
• 两个不写列表的同胞 fetchPackages 调用点（可写性礼让门、命名空间查找）也都只走共享 toast id、不写槽。

⇒ ⭐ 决定性的是你那句：把触发器标成 failed，等于声称屏幕上那些名字动过了，而它们没有。 B 的论点（端点在失败 ⇒ 屏上的列表不再能被确认是最新的）不是没道理，但它让 UI 断言一件数据不支持的事。⛔ 「复用既有姿态」的意思正是服从这个文件已有的约定，而你把那个约定量出来了。

---

⭐⭐ 实测出的响应形状，比卡面精确得多

只有一种错误信封，而且是被钉住的：GET /api/v1/packages 由 direct-mount registrar 提供（生产环境先挂载，check:route-envelope 钉住「零手写响应体」），所以每一次失败都经共享的 sendError / sendThrownError 离开，形状唯一：success:false + error:{code,message}，可达路径 401 / 403（studio.access·setup.access 能力门）/ 503（两源合并的任一半）/ 500，线上侧由 package-envelope.conformance.test.ts 钉住。

⭐⭐ 于是一个关键结论：信封自己的 success 在这里不是第二个可判定位。 sendOk 在每个 2xx 写 true，错误写入器在每个非 2xx 写 false ⇒ 它就是 !res.ok 的复述。

⇒ res.ok 是判据，信封是拿来取措辞的。 这正是我要求「先量再决定读哪个或两个都读」的答案，而且答得比问题好。

⭐ 由此推出的设计后果：5xx 波段里平台扣下了生产者自己的散文，换成通用的 INTERNAL_ERROR_MESSAGE（"Internal server error"），于是 error.code 是唯一有区分度的词 —— 这就是为什么 code 必须跟着 message 一起travel。⭐ 这不是风格选择，是从测量推出来的。

第二种形状存在且已覆盖：非 JSON 的错误体（代理返回 HTML 的 502/504），此时 res.json() 抛出 —— ⭐ 那恰恰是修复前唯一能走到 catch 的那条臂，而它给作者看的是一个 JSON 语法错误。现在容错读取会点名状态码。没有第三种形状。

---

⭐⭐ 消融里最要紧的是那半句

the negative controls stay green with the fix reverted, which proves the new pins are not restating an existing assertion and that a 'fix' merely closing the sheet could not pass this file.

⇒ ⭐ 后半句排除了退化解：一个只会「把面板关掉」的假修复过不了这个文件。这比「新钉子不是复述旧钉子」更进一步。

撤销修复：Tests 6 failed | 8 passed (14)
  6 红 = 恰好是新主张（503 不开面板 / 503 有上报 / 403 / 401 / 非 JSON 502 / 成功但缺该包）
  8 绿 = 3 条阴性对照 + #7821 的全部 5 条钉子

红的就是缺陷本身，逐字：四条上的 data-managed-id=""（面板开在了 null 包上）；AssertionError: expected "vi.fn()" to be called at least once（openManage 的 catch 从未运行、什么都没报）；以及非 JSON 那条答出一个指着代理 HTML 页面开头那个尖括号的 SyntaxError，而不是「HTTP 502」。

---

⚠️⚠️ 两条关于工具本身的发现，本席特别记下

① 一次假绿被本仓自己的门拦住了

pnpm --filter @object-ui/app-shell exec vitest ... 被本仓的 vitest 调用门拒绝（#3378：从包目录跑 vitest 会静默地跑 apps/console 的 22 个文件并报 Test Files 22 passed）。

⇒ ⭐⭐ 那是一道专为防止假绿而存在的门，而它响了。 22 passed 会被任何人读成「我的测试过了」。⛔ 从仓库根重跑才是真读数。这条值得所有席位记住。

② git checkout <ref> -- <path> 会同时写索引

恢复时显式点名 HEAD，因为裸 git checkout -- path 会从索引恢复，而那个索引刚被 git checkout ref -- path 写进了突变。

⇒ ⭐⭐ 这是一个真陷阱：用「裸 checkout」恢复，恢复出来的是突变本身，而且 git status 会显示干净 —— 一次看起来成功的恢复，实际什么都没恢复。本轮所有消融都要求「恢复由状态证明」，这条说明了为什么退出码和 git status 都不够。

---

✅ 面外那一个文件，本席批准

packages/app-shell/src/views/metadata-admin/i18n.ts 超出我给的面（StudioDesignSurface.tsx 区段 + 测试）。批准，因为报出一条新错误消息必然需要一个 i18n 键，而 formatMetadataError 就住在 metadata-admin。

你也把它量清楚了：改动纯增（git diff --numstat 读出 5 0，零行匹配 ^-[^-]）⇒ 没有既有键的值移动；读这张表的 16 个 metadata-admin 套件全过（136 tests）；并用测量确认 packages/i18n 的 all-locales-key-parity 不覆盖这张表（十个 locale 包里没有它）。

⚠️ 但下次请像 pkgsErr 那条一样放进 open_questions，而不是只在 gates 段落里带过 —— 面外文件是本席要显式批准的东西。

---

派生 #7907 —— ⚠️ 而且本卡把它变宽了

onManageChanged 的尾部（managed-snapshot 刷新，与 #7879 修的头部不同）静默吞掉失败的 fetchFullPackage ⇒ 生命周期动作之后，已打开的面板把动作前的记录当作最新呈现。

⚠️⚠️ 关键的诚实：本卡把那条臂加宽了 —— 在此之前那个 catch 只能看到 res.json() 的拒绝，现在它还能看到每一个 401/403/503/500。

⇒ ⭐ 这是「修一个吞错误的缺陷，可能让另一个吞错误的地方吞得更多」的真实实例。⛔ 这不构成不落地的理由（现状是静默 + 看不见失败，落地后是静默 + 失败可见但仍被吞，严格更好），但它必须被记下来。已按 bug + p2 上板。

⚠️ 串行约束：#7907 与本 PR 同文件 ⇒ ⛔ 本席不会在 #7906 落地之前派发它。

边界确认

/home 硬编码逐字节未动（#7373）· onManageChanged 头部逐字节未动（#7879）· 手写 fetch 有意保留（卡片选项 3；它不能复用 fetchPackages，因为 parsePackages 会裁掉这个面板需要的完整记录）。changeset 判词 patch。Clause-② no。

落地路线： CI 终态后由本席跑三条前检并出队。
