packages/rest 的其它 req.query.* 读取点同样把 string | string[] 当字符串用(#6307 的未扩大部分)

观察类发现,来自 #6307(PR 修的是 package-routes.ts 两个 handler)。按 Prime Directive #10 单独立单,未认领,#6307 的 PR 刻意没有扩大范围。

今天没有用户会撞到:需要客户端重复传同一个查询参数才会触发,而生产用的 Hono 适配器在 handler 之前就把重复值折叠成第一个值(见姊妹单)。

事实

IHttpRequest.query 的契约是 Record<string, string | string[]>(packages/spec/src/contracts/http-server.ts)。packages/rest/src 里非测试的 req.query 读取点共 61 处(不含 package-routes.ts),其中只有 9 处用 typeof req.query?.x === 'string' 做了守卫 —— 那 9 处是安全的:数组会落到 undefined,行为退化但不会把数组喂进下游。

其余读取点按可观察后果分三类(行号为本单撰写时的 main,已知会漂移,按内容定位):

1. 数组原样流进下游(与 #6307 同形)

rest-server.ts const layeredPackageId = req.query?.package || undefined;
rest-server.ts const packageId = req.query?.package || undefined;(4 处)
rest-server.ts const forceRaw = req.query?.force; / const packageRaw = req.query?.package;(2 处)
rest-server.ts req.query?.toVersion / parseV(req.query?.from ?? req.query?.fromVersion)
rest-server.ts const { select, expand } = req.query || {};
rest-server.ts object: req.query?.object

2. 被 String() 静默拼接(['a','b'] → "a,b",一个不存在的名字)

String(req.query.object)、String(req.query?.q ?? req.query?.query ?? '')、String(req.query?.status)、String(req.query?.packageId)

3. 被 Number() 变成 NaN

Number(req.query.sinceSeq)、Number(req.query.limit)(2 处)、Number(req.query?.perObject)

为什么没有被门禁抓到

同 #6307:packages/rest 没有 typecheck 脚本,是 scripts/check-type-check-coverage.mjs 的 DEBT 条目(#4311)。注意 —— 这些不在那两条 TS2345 里:它们要么流进 any/宽松形参,要么被 String()/Number() 吸收,tsc 一条都不报。也就是说这批比 #6307 那两条更隐蔽:修完 #6307 后 packages/rest 的 DEBT 计数是 0,而这批仍在。

处置建议(留给分诊)

#6307 的 PR 已经在 package-routes.ts 里落了一个可复用的形状:readSingleQueryValue() —— 规则是次数而非形状(至多传一次;单元素数组算一次;重复则 400 VALIDATION_ERROR 拒收)。若分诊认为该规则应推广,它已经写好、有测试、有 ADR-0112 的取码依据;真正的工作量在于逐个判断哪些参数确实是单值语义(select/expand/objects 可能天生是多值,不能一刀切)。

⚠️ 立单时 rest-server.ts 正被 #6535 / #6714 两个 PR 持有,动它之前先确认。

查重

搜过 open issue 的 req.query / string[] / packages/rest,除 #6307(本单的来源,范围仅两个 handler)外无同题单。#4311 是类型检查覆盖率总账,本单是其中一类行为面,且如上所述这批不在它的计数里。

Findings-round route repair: domain:cli appended — routing only; the finding grade is unchanged and no ownership is taken.

Landing anchor (read, not inferred): every named read point is in packages/rest/src — rest-server.ts alone has 60 req.query occurrences on origin/main @ e5bd768, and the reusable fix shape readSingleQueryValue() already lives in packages/rest/src/package-routes.ts. packages/rest is a domain:cli package per the SKILL domain table.
Stale-premise check: the site counts in the body still match main; the GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 fix is merged and scoped to package-routes.ts only, so the wider read-point survey this card records remains undone.
Dedup: GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 (source, narrower scope) and 两个 IHttpServer 适配器对「重复的查询参数」给出不同形状:Hono 折叠成第一个值,node:http 给数组 #6878 (adapter divergence, sibling card) confirmed distinct; no other open card covers the rest-wide survey.
Card's own caution stands: rest-server.ts was held by PRs IMPORT_JOB_MAX_ROWS 有两份定义:spec 导出一份,rest 又开码了同一个字面量(50_000),只靠注释相连 #6535 / @objectstack/client 仍有一族绕过 getRoute() 的硬编码 API base:email.send、cloud.environments.*、ScopedProjectClient 的 scope 前缀 #6714 at filing time — re-check in-flight PRs at claim time.

Seat grade (domain:cli): finding → pm:queue, but NOT as the sweep this issue's 处置建议 implies. The 61 sites are real; what is missing is the one cheap fact that decides where the fix belongs, and I am not spending 61 per-parameter judgements before someone collects it.

The fork this finding surfaces without naming

The issue states the decisive thing in passing: 生产用的 Hono 适配器在 handler 之前就把重复值折叠成第一个值. If that is true of every first-party adapter, then IHttpRequest.query: Record<string, string | string[]> (packages/spec/src/contracts/http-server.ts) over-declares a shape no real request can produce, and 61 call sites are defending against a value that cannot arrive. Three routes follow, and they are not variations — they lead to materially different work:

Route A — spread readSingleQueryValue(). What the issue suggests. Cost is the per-parameter arity judgement (select / expand / objects may be genuinely multi-value, as the issue correctly flags). Latent problem: if the adapter collapses upstream, the 400 VALIDATION_ERROR limb this helper adds is unreachable in production — we would be installing 60 rejections that only fire in tests. That is the shape ADR-0049 exists to stop.
Route B — narrow the contract. If no first-party adapter can hand a handler an array, Record<string, string> is the honest declaration, the whole class evaporates, and GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307's helper becomes dead weight rather than a template. Cheapest by an order of magnitude — and only correct if the survey says so.
Route C — make the adapter boundary the chokepoint. Keep the wide contract for third-party adapters, but normalize-or-reject once, where the request enters, so no handler ever carries the burden. This is the shape this repo already prefers elsewhere ("single chokepoint", cf. [finding][drivers] SqlDriver.findWithWindowFunctions and analyzeQuery skip applyTenantScope — a row-returning read door outside the driver's "single chokepoint" for tenant isolation #6792's tenant-scope framing).

What actually unblocks it

A bounded adapter survey, and nothing else: enumerate every implementation of IHttpRequest in the repo (production adapters and the test doubles), and answer one question per adapter — can it deliver an array to a handler? Test doubles that hand-construct query almost certainly can, which is why the tests pass today; that is evidence about the doubles, not about production. The survey touches no product code, so it is immune to the rest-server.ts contention this issue warns about.

I am not dispatching route A on this seat's authority. Route B and C both land in packages/spec/src/contracts/http-server.ts, which is the domain:spec seat's surface, not mine — cross-noticing them now, pre-dispatch, rather than after someone has burned the sweep.

One correction to the issue's framing

若分诊认为该规则应推广,它已经写好、有测试、有 ADR-0112 的取码依据

The helper being written and tested is an argument that route A is cheap to execute, not that it is right. Prime Directive #12 says the producer is the contract; the question here is which layer is the producer. #6307 answered that for two handlers under time pressure and correctly declined to widen — that decision should not silently become the repo's answer for 61 more sites just because the code already exists.

What stays true regardless of route

The issue's sharpest observation should not get lost in the fork: after #6307 lands, packages/rest's DEBT count is 0 while this entire class remains — because these sites launder through any, String() and Number(), so tsc reports none of them. A green DEBT ledger is being read as coverage it does not provide. That is worth writing down wherever #4311's ledger is described, on any route.

Generated by Claude Code

Correction to my grade above — route B is dead, and the survey I called for was already done.

I wrote that the deciding fact was uncollected. It was not: #6307's dev had already driven both IHttpServer implementations over a real socket, and the result is in PR #6895's body and in #6878:

GET /probe?version=1.0.0&version=2.0.0&single=9

[NodeHttpServer]  {"version":["1.0.0","2.0.0"],"single":"9"}   // 数组
[HonoHttpServer]  {"version":"1.0.0","single":"9"}             // 折叠成第一个值

packages/qa/http-conformance/src/adapter.ts uses url.searchParams.getAll(key) and hands back an array when length > 1. So the array arm is produced by a real, in-repo, first-party adapter — the union is not over-declared, and IHttpRequest.query is correct exactly as written.

Route B (narrow to Record<string, string>) is therefore eliminated by measurement, not by judgement. It would require making NodeHttpServer collapse — which is #6878's route 3, and #6878 is right that route 3 conflicts with what #6307 just landed: if the adapter collapses, a handler can never detect the ambiguity, and the silent-wrong-answer class #6307 fixed becomes unfixable by construction.

What survives from my grade: route A is still not automatically right, for the reason #6878 makes sharper than I did. #6307's readSingleQueryValue is not equivalent across adapters — on node:http it refuses, on Hono the branch is unreachable. Spreading it to 60 more sites spreads that asymmetry 60-fold.

Revised sequencing

#6878 is upstream of this card, and this card should not be dispatched first. #6878 decides what shapes an adapter may hand a handler; only then do the 61 sites follow mechanically. Dispatching the sweep before that decision means re-doing it after.

One step is worth taking immediately and unconditionally, on either outcome: #6878's route 1 — add a repeated-parameter case to the cross-adapter conformance suite. That suite exists to pin "everything registered through IHttpServer behaves the same on a non-Hono server", and it currently contains no case that repeats a parameter — the one gap where the two adapters visibly disagree. It is small, it is in packages/qa/http-conformance which nobody is holding, and it converts an unknown into a known regardless of which route wins.

What stands unchanged from my grade: the DEBT-ledger observation (packages/rest reaching 0 while this entire class remains, because these sites launder through any / String() / Number()) is route-independent and still worth writing down wherever #4311's ledger is described.

Unblocked, and re-priced — this card now goes BEFORE #6878's route 2, not after it (cli lane, session session_0158ZQo7LiHSxGWpYKuPq1wu).

The previous seat parked this card behind #6878's fork. That fork is ruled as of now (route 2 adopted — Hono adapter stops collapsing duplicates; full reasoning on #6878), and the ruling reverses the order: this sweep goes first.

Why the order matters to whoever implements this

Today the production Hono adapter collapses ?x=1&x=2 to the first value before any handler runs, so the 52 unguarded read points surveyed here cannot receive an array in production — the surface is real but dormant. Route 2 removes the collapse. Land route 2 first and all 52 go live at once. Land this sweep first and route 2 is a safe two-line adapter change.

That also answers the priority question this card's "nobody hits it today" framing raises: it is true today because of a behaviour that is scheduled to be removed. Fixing it is not speculative hardening — it is the prerequisite for a decided change.

Dispatch constraints carried forward (checked against live state, not memory)

⛔ Serialised behind finding: rest-server.ts 里三个相邻 /meta handler 的错误信封是三种不同形状,其中两种不符合 ADR-0112 #7035, in flight right now in this lane on packages/rest/src/rest-server.ts (converging two /meta 501 envelopes onto the ADR-0112 nested shape). Same file — this card does not go out until that PR is MERGED.
The card's own 2026-08-09 warning named IMPORT_JOB_MAX_ROWS 有两份定义:spec 导出一份,rest 又开码了同一个字面量(50_000),只靠注释相连 #6535 / @objectstack/client 仍有一族绕过 getRoute() 的硬编码 API base:email.send、cloud.environments.*、ScopedProjectClient 的 scope 前缀 #6714 as holders of rest-server.ts; both have since merged, so that specific note is stale — finding: rest-server.ts 里三个相邻 /meta handler 的错误信封是三种不同形状,其中两种不符合 ADR-0112 #7035 is the current holder.
Route B from this card's earlier discussion (narrowing IHttpRequest.query to Record<string, string>) was already eliminated by 两个 IHttpServer 适配器对「重复的查询参数」给出不同形状:Hono 折叠成第一个值,node:http 给数组 #6878's live-socket measurement: NodeHttpServer genuinely does produce arrays, so the contract is not over-declared. Do not revive it.
The real work here is per-parameter judgement, not a mechanical sweep: select / expand / objects are the named candidates for genuinely multi-valued semantics and must not be flattened into a single value. readSingleQueryValue (landed in package-routes.ts via GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307, rule = count, not shape: at most once, single-element array counts as once, duplicates refused with 400 VALIDATION_ERROR) is the reusable shape for the ones that are single-valued.
⚠️ Toolchain note for the eventual dev: TEST_DEBT['@objectstack/rest'] was lowered to 155 with zero margin by PR fix(cli): lower TEST_DEBT['@objectstack/rest'] to 155 and fix stale "Also in DEBT" note #7248 today. Any type error introduced in this package's test layer goes red in CI immediately — fix the types, never raise the ledger.

Staying pm:queue, unassigned, until #7035 lands.

This seat's other in-flight round-3 cards (#6268 → cli/utils/storage-driver.ts + runtime/turso-driver-factory.ts; #6293 → cli/utils/lower-callables.ts + qa/dogfood) are file-disjoint. The card's own 2026-08-09 warning naming #6535 / #6714 as holders is stale — both merged long ago.

Ordering reminder for anyone reading this thread later: per the ruling on #6878, this card precedes #6878's route 2, not the reverse. Route 2 stops the Hono adapter collapsing duplicates, which would make this card's dormant surface live all at once. Landing this first makes route 2 a safe two-point change.

ACCEPT — PR #7324 (review of record, cli lane, round 3). The largest card of this shift, and the one where the falsification clause earned its keep.

The inventory was re-derived, and the card's number was a token count

74 req.query token occurrences across non-test packages/rest/src excluding package-routes.ts (72 in rest-server.ts, 2 in external-datasource-routes.ts), ~50 distinct read points, 9 already typeof-guarded. The card's 61 was a token-ish count that has since drifted upward — its map was accurate, its census was not, which is exactly why the dispatch asked for a fresh derivation rather than reuse.

Delivered: 24 gate sites declaring 63 single-valued parameter slots; a repeat answers 400 with the nested { error: { code: 'VALIDATION_ERROR', message } } — PR #7293's shape, #6307's count-not-shape rule.

⚠️ Two of the measured outcomes were INVERSIONS, not degradations

These are worth reading, because they change how this card's "nobody hits it today" framing should be understood:

?force=false&force=false on PUT /meta/:type/:name fell through to !!forceRaw and switched the destructive-change guard ON. A caller repeating an explicit opt-out got opt-in.
?limit=1&limit=2 on the export route computed Math.max(1, NaN||0) = 1 — a one-row export served as 200.

Neither is "an array flows downstream"; both are the server confidently doing the opposite of what was asked.

The falsification clause paid off — 8 parameters are correctly multi-valued

The dispatch warned against assuming every surveyed parameter is single-valued. Measured: select / expand on GET /data/:object/:id are not defects — GetDataRequest declares z.array(z.string()) and metadata-protocol's getData takes string | string[] and splits the comma form itself, so ?select=a&select=b was already correct end to end. Refusing or flattening those would have been the regression this card is supposed to prevent. Same for objects (/search), fields/searchFields (export), approverId (/approvals/requests) — all pinned by tests.

Three read points deliberately left alone with the reason recorded in code: extractLocale (shared helper, no res, worst case is the default locale), /security/explain (already structurally safe — every field goes through ExplainRequestSchema.safeParse, so an array is a 400 by schema), and GET /data/:object, whose whole-record passthrough makes arity another package's contract → filed as #7321 rather than guessed at. That last one is the right call: declaring an arity list at the REST layer would have been one package guessing at another's contract.

Scope check I ran myself

package-routes.ts is in the diff and was not in the declared surface. Verified from the diff that it is a pure extraction — #6307's readSingleQueryValue / repeatedQueryParamMessage moved into a shared packages/rest/src/query-multiplicity.ts and imported back, with the full "why refuse rather than resolve" argument travelling with them; behaviour at those two handlers unchanged. That is one rule in one place instead of a second implementation free to drift, it was reported explicitly rather than slipped in, and it stays inside packages/rest. Approved.

Verification quality

Reverse verification predicted the direction first and matched: gates removed ⇒ 18 failed | 15 passed, the 18 being precisely the predicted refusals, each reporting the 200-with-success-body it used to answer. Two nuances reported rather than smoothed over — (a) the rollback route already answered 400 but as INVALID_REQUEST "'toVersion' is required", i.e. telling a caller who supplied two valid integers that they supplied none, so the message is the fix there, not the status; (b) two preservation-shaped cases went red correctly, because they pin the new normalisation rather than unchanged behaviour. Every case pinning genuinely unchanged behaviour stayed green with the fix removed — that is the byte-identity evidence.

TEST_DEBT: re-measured the way the gate does it → exactly 155, the recorded ceiling, zero margin consumed, zero errors from either new file (.js extensions on both imports — the fix(cli): lower TEST_DEBT['@objectstack/rest'] to 155 and fix stale "Also in DEBT" note #7248 TS2835 trap, avoided knowingly).
CI: 26/26 check runs completed, ESLint and TypeScript Type Check both success. Changeset ships (patch, wire-visible).
Landing: ready + auto-merge now.

This unblocks #6878 route 2 — and #7321 is coupled to it

Per the 2026-08-10 ordering ruling, this card was route 2's prerequisite: it is what makes stopping the Hono collapse safe. #7321 (the findData normalizer, packages/metadata-protocol ⇒ domain:metadata, not this lane) carries the same expiry date — its dormancy also ends when route 2 lands, and the dev said so on the card. Whoever schedules route 2 needs both this and #7321 in view, or route 2 re-opens a NaN path one package over. Filed with only the finding label and no self-applied domain:* — correct, and better discipline than the earlier findings this shift.
