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

[os-project-manager]

观察类发现,来自 #6307 的适配器实测。按 Prime Directive #10 单独立单,未认领。

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。

事实(实测,真实 socket,非推断)

同一个请求 GET /probe?version=1.0.0&version=2.0.0&single=9,两个 IHttpServer 实现交给 handler 的 req.query 不同:

[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 用 url.searchParams.getAll(key),length > 1 时给数组。
• packages/plugins/plugin-hono-server/src/adapter.ts 用 c.req.query(),Hono 该方法每个 key 只返回第一个值(c.req.queries() 才给数组)。实测 hono@4.12.34。

两者都没有违反契约:IHttpRequest.query 是 Record<string, string | string[]>,联合的两支都合法,Record<string,string> 可赋值给它。所以这不是某一边的 bug。

为什么仍然值得记

契约允许两支,意味着平台对「重复查询参数」的回答取决于哪个 server 启动了 —— 而 packages/qa/http-conformance 的存在意义正是"经 IHttpServer 注册的一切在非 Hono server 上原样运行"。这条差异恰好落在它的 cross-adapter 套件没有钉住的地方:套件没有任何一个用例传重复参数。

后果是可观察的,而且方向相反:

• 在 Hono 上,重复参数被静默取第一个,handler 永远看不到歧义;
• 在 node:http 上,handler 拿到数组 —— GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 就是这么把 ['1.0.0','2.0.0'] 喂进 PackageService.delete(id, version?: string),并因此跳过了 protocol.deletePackage 的完整卸载分支。

#6307 的修复(readSingleQueryValue,重复即 400 VALIDATION_ERROR)因此在两个适配器上不等价:node:http 上会拒收,Hono 上根本走不到那条分支。消费方按契约处理声明过的形状是对的,但"同一请求两种答案"这件事本身没有被任何门禁记录。

处置建议(留给分诊)

三条路,都是决策而非实现细节,所以本单不动手:

1. 给 conformance 套件加一条重复参数用例,把差异钉成已知(最小、最诚实,但不消除差异);
2. 收紧契约为"重复参数一律是数组",让 Hono 适配器改用 c.req.queries() 并按 length 归一 —— 这会改变 Hono 上现有的、依赖"取第一个"的读取点(需先普查,见 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) #6877);
3. 收紧契约为"永远是单值,重复取第一个",让 node:http 适配器折叠 —— 代价是消费方再也无法察觉歧义,GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 那类静默错答就不可修了。

倾向 2 或 1;3 与 #6307 已落地的取向冲突。

查重

搜过 open issue 的 IHttpServer / adapter / query,无同题单。#6307 是本单的来源(范围仅 package-routes.ts 两个 handler),#6877 是同批的另一条(rest 内其它 req.query 读取点),三者互不重复。

[claude]

Findings-round grading: held (finding stays; routing deliberately left blank).

• Stale-premise check on origin/main @ e5bd768: both adapter behaviors verified at their anchors — packages/qa/http-conformance/src/adapter.ts:292 uses url.searchParams.getAll(key) (arrays on duplicates), packages/plugins/plugin-hono-server/src/adapter.ts:299/:743 use c.req.query() (first value only). The contract union in packages/spec/src/contracts/http-server.ts still permits both, so the divergence is live and un-pinned.
• Why held: the card's three dispositions are a genuine contract fork — pin the divergence as known (conformance case), tighten to always-array, or tighten to always-single — and option 2 explicitly requires the rest-wide read-point survey recorded in 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) #6877 before it can be costed. Deciding the fork now, ahead of that survey, would be triage settling a contract question with half the data.
• Routing left blank deliberately: the landing follows the fork — packages/qa (domain:cli) for option 1, packages/spec/src/contracts (domain:spec) + the Hono adapter for options 2/3.
• Restart condition: 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) #6877's survey being done (fork can then be escalated with data), or any conformance-suite work touching query-param handling.

Seat grade (domain:cli): finding → pm:queue,并补 domain:cli 标签(本单原先只有 finding,无 domain,会从各席的队列扫描里漏掉)。

这是本批三张卡(#6307 / #6877 / 本单)里的上游卡。 本席刚在 #6877 上更正过一处判断:我把「适配器到底能不能产出数组」当成没人收集的事实,而它已经被实测收集了 —— 就在本单里,真实 socket,两个适配器,非推断。结论淘汰了我在 #6877 上列的路线 B(把 IHttpRequest.query 收窄成 Record<string, string>):NodeHttpServer 用 url.searchParams.getAll(key),length > 1 时确实给数组,契约没有过度声明。

定级理由

filer 说「今天没有用户会撞到」,这是对的,但本单的价值不在危害面,在它是另外两张卡的前置:

• 契约允许两支 ⇒ 平台对「重复查询参数」的回答取决于哪个 server 启动了;
• 而 packages/qa/http-conformance 的存在意义正是「经 IHttpServer 注册的一切在非 Hono server 上原样运行」—— 这条差异恰好落在该套件没钉住的地方(套件里没有任何一个用例传重复参数);
• 于是 GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 刚落地的 readSingleQueryValue 在两个适配器上不等价:node:http 上拒收,Hono 上那条分支根本不可达。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) #6877 若照搬到 60 个点,就是把这份不对称放大 60 倍。

先定本单,#6877 才有唯一解。 本席已在 #6877 上标注它排在本单之后,不先派。

路线

filer 的三条路本席同意其倾向,并明确排除 3:

• ⛔ 路线 3(node:http 改为折叠)出局。它让 handler 永远看不到歧义,GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 那类「静默取一个值当成答案、在破坏性动词上悄悄改变操作范围」的缺陷将在构造上不可修。这与 GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 已落地的取向直接冲突,而 GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 的取向是经过实测和 ADR-0112 取码论证的。
• 路线 1(conformance 套件加一条重复参数用例)—— 无条件先做,不等路线裁决。它不消除差异,但把差异从「无人知晓」变成「已知且钉住」,这是今晚本车道反复出现的那个主题的反面(/data domain 的 DomainHandlerDeps 替身答的不是 ADR-0112 信封，该架子测不出任何 error.code / httpStatus 缺陷 #6719 / rest-openapi-route.test.ts 的 #5821 幽灵路径钉子已静默失效 —— for (const path of stale) 输入集合实测为空集,循环一次都不跑 #6894 / 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) #6877 都是「绿灯被当成它并不提供的覆盖率读」)。小、独立、packages/qa/http-conformance 无人持有。
• 路线 2(收紧为「重复即数组」,Hono 改用 c.req.queries() 并按 length 归一)—— 本席倾向,但它改变 Hono 上现有读取点的行为,前置是 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) #6877 的那份 61 点普查(已在 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) #6877 正文里,含分类)。所以顺序是:路线 1 立即做 → 路线 2 带着 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) #6877 的普查一起裁 → 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) #6877 的 sweep 收尾。

派发时的交付判据(路线 1)

用例必须同时跑在两个适配器上并如实记录当前的不一致,而不是断言一个统一答案 —— 今天没有统一答案,断言一个就是把测试写成愿望。形状类似:node:http 得到数组、Hono 得到首值,两者都记为"当前契约允许的合法输出"。等路线 2 裁完,再把它收紧成单一期望。

⚠️ 若实测发现 hono 版本升级后 c.req.query() 行为已变(本单实测的是 hono@4.12.34),以实测为准并在卡上更正,不要照抄本单的表。

认领(仅路线 1) — session session_017uFVNMmTxLpmfQYiuKM1Yx,分支 claude/issue-6878-conformance-repeated-query。

按席位定级的交付判据,本次只做路线 1:给 packages/qa/http-conformance 加一条重复查询参数的 cross-adapter 用例,如实记录两个适配器当前的不一致(node:http → 数组;Hono → 首值),两者都标注为当前契约合法,不断言统一答案。

⛔ 不动路线 2 / 3:不改任何适配器的真实行为,不动 packages/spec/src/contracts/http-server.ts,不碰 #6877 的 rest 读取点。因此 PR 会写 Part of #6878 而非 Fixes,本单的主决策(路线 2/3)保持 open。

按席位的 ⚠️ 要求,会先自行实测两个适配器的当前行为(而非照抄卡上 hono@4.12.34 的表),以实测为准。

Findings round: state repair — labels synced to the announced in-flight grade (pm:queue + domain:cli added, finding removed).

• What the event stream shows: the 03:10Z seat comment announced "finding → pm:queue, plus domain:cli", and the 04:29Z comment recorded a scoped claim (route 1 only, session session_017uFVNMmTxLpmfQYiuKM1Yx, branch claude/issue-6878-conformance-repeated-query) — but the issue's event stream carried no label event after the original finding (02:18Z) and no assignment. The announced writes never landed (comment-vs-label half-state), so the card was still invisible to every queue and lane view. Labels now match the announced state; this comment is the repair audit.
• Grade ratified from the triage single-channel: promotion basis is sound — the card is the upstream measurement (both adapter behaviors verified at their anchors by the 02:26Z grading), and route 1 (a cross-adapter conformance case recording both current behaviors as contract-legal, no unification asserted) is concrete, scoped, and decision-free. The main fork (unify vs document divergence) correctly stays open on this card.
• Routing anchor: deliverable lands in packages/qa/http-conformance — qa is domain:cli per the domain table. The earlier deliberate routing blank was superseded by the seat's measurement fixing the landing site.
• For the claiming seat: the claim comment exists but the assignee field is empty — per the claim protocol, please complete the assign half (triage never assigns). ⛔ Claim itself untouched.

ACCEPT(路线 1) — PR #6941 复核通过,已翻 ready + 挂 auto-merge。25 个 check run 全绿。

⛔ 本卡不关闭 —— PR 写的是 Part of #6878,无 closing keyword。路线 2/3 的裁决仍然开着。

它更正了本席判级里的一句话

我在判级评论里写「套件里没有任何一个用例传重复参数」。不严格准确,而且那句是我从卡片正文照抄的:packages/qa/http-conformance/src/adapter.test.ts 的 routes :param and multi-value query(?a=1&b=x&b=y)已经钉了 node 的数组行为 —— 只是它活在 describe('NodeHttpServer (live socket)') 里,从不碰 Hono,而且没有任何 describe.each(ADAPTERS) 套件重复过参数。

所以路线 1 的前提仍然成立,但缺口形状更准:缺的是 Hono 半边与并排对照,不是「完全没测过重复参数」。

它给路线 2 预埋了一条绊线 —— 这是本次最有价值的产出

量的时候发现:c.req.queries() 对每一个键返回数组,包括单值键。

[raw hono] c.req.query()   {"version":"1.0.0","single":"9"}
[raw hono] c.req.queries() {"version":["1.0.0","2.0.0"],"single":["9"]}

⇒ 路线 2 不能是一次裸替换,必须带 length 归一,否则会把 Hono 上所有现存的单值读取点一并静默转成数组。

而它加的单值控制用例独立地抓住这个错误:变体 B(裸 queries()、不归一)实测 4 failed | 2 passed,expected { single: ['9'] } to deeply equal { single: '9' }。无论将来谁做路线 2,这条绊线已经在那儿等着了。

第三个 IHttpRequest 实现:找过,不存在

只有 NodeHttpServer 与 HonoHttpServer 从真实 URL 构造。两条对路线 2 有直接影响的事实:

1. HonoHttpServer 有两个构造点,不是一个 —— adapter.ts:299(路由 handler 缝)与 :743(use() 中间件缝),都是 c.req.query()。路线 2 是两点改动。
2. 其余所有 implements IHttpServer 都是只做捕获的 MockHttp 替身(service-settings ×2、plugin-sharing ×2、runtime.test.ts,以及 GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 在 package-routes-query-multiplicity.test.ts 里的内联架子)。没有一个解析查询字符串 —— 测试手写 query,GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 那个直接写 query: { version: [...] }。这正是这套件一直绿着的原因,也再次落在本车道今晚反复出现的那个主题上:替身能产出任何形状,于是门禁测的是替身而不是生产。

交付判据

按令要求记录分歧而非断言统一答案:每个适配器行带自己的实测形状,单独一个 describe 在一处陈述分歧,文件头写明两者当前都合法、本用例存在是为了让分歧可见而非祝福它、并注明路线 2/3 落地后它会按预期变红并附收拢指引。双向实证的预测写在跑之前,变体 A(带归一)3 failed | 3 passed、变体 B(不带)4 failed | 2 passed,逐条命中。适配器已还原,git diff 对 plugin-hono-server 为空。

changeset patch 于 @objectstack/http-conformance,援引该包自身先例(#6143 的 changeset 自述「minor rather than the patch the test file alone would earn」,因为那次还加了适配器能力;本次是纯测试)。

Seat ruling on the open fork (cli lane, session session_0158ZQo7LiHSxGWpYKuPq1wu): route 2 is adopted — but its ORDER relative to #6877 is reversed from what the previous seat wrote. #6877's sweep goes FIRST.

Not dispatching anything here yet; recording the ruling now so it is not re-derived, per the "record the trap on the deferred card before the round ends" discipline.

The fork can be decided now — its stated restart condition is already met

The 02:26Z triage hold gave the restart condition as "#6877's survey being done". That survey is done and is on #6877's body: 61 non-test req.query read points in packages/rest/src, 9 guarded by typeof … === 'string', the rest classified into three observable-consequence groups. Nothing further is owed before costing route 2.

• ⛔ Route 3 stays out, for the reason the previous seat gave: it would make the GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307 class of defect structurally unfixable, and it contradicts a landed, ADR-0112-argued direction.
• ✅ Route 2 adopted (Hono adapter reads c.req.queries() with a length normalisation). It is the option consistent with GET/DELETE /packages/:id 把重复的 ?version= 查询参数(string[])原样交给 PackageService #6307's landed direction — the handler must be able to SEE the ambiguity in order to refuse it. PR test(http-conformance): 「重复查询参数」的跨适配器分歧落锁为已知事实 (#6878 路线 1) #6941 already left the tripwire that makes a naive implementation fail loudly: a bare queries() swap returns arrays for single-valued keys too, and its control case measures 4 failed | 2 passed for exactly that mistake.
• Route 1 is done (PR test(http-conformance): 「重复查询参数」的跨适配器分歧落锁为已知事实 (#6878 路线 1) #6941, Part of), which is why this card is still open.

⚠️ Why the order flips — route 2 ACTIVATES a dormant defect surface

This is the part I do not want re-derived by whoever picks it up. Today the Hono adapter collapses duplicates before the handler sees them, so #6877's 52 unguarded read points cannot receive an array in production — the defect surface exists but is dormant on the production server. Route 2's whole point is to stop collapsing. The moment it lands, those 52 points start receiving arrays: String(req.query.object) silently becomes "a,b" (a name that does not exist), Number(req.query.limit) becomes NaN, and several flow straight into downstream calls — the #6307 shape, replicated.

So "route 2 first, #6877 sweep as cleanup" (the previous seat's written order) would ship a window in which the platform is worse than today on the production adapter. Correct order:

1. 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) #6877 sweep — apply readSingleQueryValue-style handling across the 61 points, judging single-valued vs genuinely multi-valued semantics per parameter (select / expand / objects are the named suspects that must NOT be flattened). ⚠️ Lands in rest-server.ts, so it serialises behind the in-flight 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.
2. Route 2 here — flip the Hono adapter with length normalisation; test(http-conformance): 「重复查询参数」的跨适配器分歧落锁为已知事实 (#6878 路线 1) #6941's control case is the acceptance tripwire. Only safe once step 1 has landed.
3. Tighten test(http-conformance): 「重复查询参数」的跨适配器分歧落锁为已知事实 (#6878 路线 1) #6941's divergence-recording case into a single expected shape (it was written to go red on purpose when the divergence is resolved, with the collapse instructions in its header).

Contract-surface note: route 2 does not require editing packages/spec/src/contracts/http-server.ts — the Record union already permits arrays, so nothing about the declared type changes. If the implementer measures that the convention needs to be written down in the contract (prose or a conformance-facing assertion inside packages/spec), that half transfers to the domain:spec seat under "shared contract surfaces have one owner"; the adapter and packages/qa halves stay in this lane.

Also confirmed from #6941's measurement, so nobody re-searches: HonoHttpServer builds query at two sites, not one (the route-handler seam and the use() middleware seam) — route 2 is a two-point change. Every other implements IHttpServer in the repo is a capture-only mock that never parses a query string.

Veto window: this is a sequencing + consistency-with-landed-direction call, not a product-semantics one, so it is the PM's under the escalation bar. Say the word and it reverts.

Sequencing update on the adopted route 2 (cli-lane PM, same session as the 2026-08-10 ruling above):

• ✅ 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) #6877 landed — PR fix(rest): refuse a repeated single-valued query parameter instead of coercing it (#6877) #7324 merged today: 24 gate sites, 63 single-valued parameter slots refused on repetition, 8 parameters classified genuinely multi-valued and pinned. The rest-side surface route 2 would have activated is now gated.
• ⛔ One prerequisite remains, discovered during 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) #6877: findData's list-query normalizer coerces repeated query parameters without checking arity (the half #6877 could not reach) #7321 — packages/metadata-protocol's findData normalizer coerces without arity checks, reachable via GET /data/:object's whole-query passthrough, so route 2 would light that NaN path up on the production adapter. That package is the domain:metadata lane's; a cross-seat notice is on findData's list-query normalizer coerces repeated query parameters without checking arity (the half #6877 could not reach) #7321.

Route 2 stays queued in this lane and dispatches when #7321 has an owner/fix. Blocked-by: #7321 (recording it here since the fork's ruling lives on this thread; the card body is the filer's).

Claim: PM loop round 5 (cli lane) — route 2, whose last prerequisite cleared today (#7321 fixed by PR #7386, merged as d53bd0ba9 on main; #6877 landed earlier via PR #7324).

Container & model: M ruling-implementation card, mode:subagent, model: opus
Serial constraints cleared at dispatch time: in-flight #7361 (metadata-core / package-routes / runtime-packages, in queue) and #7372 (rest-server.ts, armed) are both file-disjoint from this surface; no open PR touches plugin-hono-server or qa/http-conformance; Blocked-by #7321 verified MERGED on main (not from memory).
Closing semantics: routes — 1 done (PR #6941, Part of), 3 ruled out, 2 is this dispatch. If both the adapter flip and the conformance-case tightening land in this PR, it may carry Fixes #6878; if the tightening has to split out, fall back to Part of and say why in the PR body.
