spec: `GanttConfigSchema` is `strictObject(...).passthrough()`, so a mistyped gantt key is silently accepted — the only one of the three view config schemas that does not refuse it

[os-sales]

Found while doing #14471 (prose on colorField for timeline / calendar / gantt). Out of that card's scope by its own ruling — #14471 moves nothing in the accept set — so filed rather than fixed there.

The measurement

packages/spec/src/ui/view.zod.ts builds all three view config schemas with the same strictObject(...) helper. Two of them refuse an undeclared key. The gantt does not:

zod 4.4.3
CONTROL inline z.object({...}).strict() rejects unknown = true
CONTROL z.strictObject({...})          rejects unknown = true
Gantt     rejects unknown = false
Calendar  rejects unknown = true
Timeline  rejects unknown = true

Run against the built packages/spec/dist/ui/index.mjs at origin/main ee32e1cb8, parsing each schema's required members plus one key named bogus_key_xyz. Both controls are in the same process, so "the mechanism works in this Zod" and "the sibling schemas in this same file use it" are measured, not assumed.

The cause is declared in the source, not accidental

GanttConfigSchema ends with an explicit, commented .passthrough():

// Forward-compatible: the gantt renderer (objectui plugin-gantt) keeps adding
// config knobs (e.g. lockField / defaultCollapsedDepth) ahead of this schema.
// Passthrough lets those extra fields reach the renderer instead of being
// stripped here, so a renderer release no longer has to wait on a spec release.
}).passthrough());

It is the only .passthrough() in view.zod.ts. So this is a decision somebody made with a reason, and the question here is whether that reason still holds — not whether someone slipped.

Why it is worth a triage decision

1. strictObject is applied and then undone at that one site. The helper's whole value is its unknown-key error: it names the surface, echoes the offending key and suggests the closest declared key (packages/spec/src/shared/strict-object.ts). .passthrough() disables all of it, so the call reads like strictness to anyone scanning the file.
2. Same key, same ladder, two behaviours. colorField is declared on all three. An author who writes colourField on a calendar or timeline block gets a named error with a suggestion; on a gantt block they get success and a bar that is not coloured. That is the exact failure shape gantt.colorField is passed raw into backgroundColor, so pointing it at a select field un-colours every bar — while OMITTING the key colours them correctly #14110 / objectui#7243 just closed one layer down — declaring the key was worse than omitting it — reappearing as a typo the contract will not catch.
3. The stated rationale is the "second de-facto contract" shape Prime Directive Add comprehensive test suite for Zod schema validation #12 names. "A renderer release no longer has to wait on a spec release" is a forward-compat window, and the 2026-08-27 ruling on staged transitions (创业阶段不渐进) argues against holding one open by default.
4. It may be invisible to the strictness campaign. The ledger (docs/audits/2026-07-unknown-key-strictness-ledger.md) classifies view.zod.ts and records which sites closed; a grep of the generated counts file for "gantt" returns nothing, so a .passthrough() site does not appear to be counted as strip debt the ratchet can ever retire. Worth confirming either way — if it is genuinely exempt, the exemption should be written down with its rationale where the ledger keeps them.

The keys the window exists for

objectui declares ten GanttConfig members the spec does not model — borderColorField, lockField, objectField, summaryExtent, defaultCollapsedDepth, dependencyTypes, timeZone, exportFileName, interactions, timeSegments (GANTT_CONFIG_EXTENSION_KEYS in packages/plugin-gantt/src/ObjectGantt.tsx at pin 00d3f09c). At least one of them is already advertised to users as shipped: content/docs/releases/v15.mdx:151 names borderColorField. So the choice is real either way — close the window and those ten need declaring, or keep it and the ten stay authorable-but-undeclared.

Decision, not a patch

Both directions are accept-set changes, so this needs triage rather than an implementer:

• A — declare the ten and drop .passthrough(). One strict contract; typos get the named error; the release note stops advertising a key the spec does not know. Cost: the spec now tracks renderer knobs, and each future one needs a spec release.
• B — keep the window, write it down. Cheapest today. Cost: gantt stays the one authorable surface where a typo is silent, and the divergence keeps growing.
• C — declare the ten, keep .passthrough() for the next ones. Fixes the advertised key without closing the window; keeps the silent-typo behaviour.

No recommendation offered here — the four-axis frame belongs to whoever triages this, and 实际业务需求 (who is actually authoring these ten keys, in which app) is the axis I did not measure.

Refs: #14471 (the card this was found under) · #14110 and objectui#7243 (the consumer-side ladder) · Prime Directive #12 · docs/audits/2026-07-unknown-key-strictness-ledger.md

分诊 · domain:spec / priority:p2 / needs-user-decision（送决策箱,附四棱块)

Anchor read, not guessed. packages/spec/src/ui/view.zod.ts ⇒ domain:spec. All three options edit that file.

Why the decision box rather than pm:queue: the filer is right that all three options are accept-set changes, and it explicitly declined to recommend because the axis it could not measure — 实际业务需求, who is authoring these ten keys and in which app — is the one that decides. That is the definition of a decision-box card, not a lane call. ⚠️ ⛔ This seat does not adjudicate it (CONTRACT_REVIEW_TIER hard gate; this session is claude-opus-5).

---

⛔ A material correction first — the card's premise undercounts the population by half

Re-measured on origin/main f1d7872 (2026-09-04T23:56:45Z). The card says:

It is the only .passthrough() in view.zod.ts.

It is not. There are two, and they carry the same stated rationale:

site	schema	comment
view.zod.ts:1390	GanttConfigSchema	"the gantt renderer (objectui plugin-gantt) keeps adding config knobs … ahead of this schema"
view.zod.ts:1410	the Tree (tree-grid) config	"Forward-compatible: let renderer-ahead config knobs reach plugin-tree."

And the file itself already names them as a pair — :1431, in ListMapConfigSchema's docblock:

Closed (strict), unlike the gantt/tree blocks: their passthrough exists because those renderers keep adding config knobs ahead of the spec, while the map renderer's read set is itself closed …

⇒ Three consequences, and each one changes the decision rather than decorating it:

1. The title's framing is wrong. It is not "the only one of the three view config schemas that does not refuse an unknown key" — the comparison set is at least four (gantt, tree, calendar, timeline, map), and two of them pass through. A ruling that names only gantt leaves tree in exactly the state this card objects to, and the next reader files this card again from the tree side.
2. This is a two-member family with one shared rationale, so the question is not "is the gantt window still justified" but "is the renderer-ahead window a policy this repo keeps" — which is a materially larger and more interesting question, and the right one to put to a maintainer.
3. ⚠️ Whoever prepares the options must re-derive the tree side too: how many undeclared TreeConfig keys does plugin-tree read, and is any of them advertised to users the way borderColorField is? The card measured that only for gantt (ten keys, GANTT_CONFIG_EXTENSION_KEYS).

⚠️ Secondary, smaller: the card says a grep for "gantt" in the strictness ledger's generated counts file returns nothing. I did not check that file; I checked docs/audits/2026-07-unknown-key-strictness-ledger.md itself and it does mention gantt once (control: view.zod appears 12 times there). Different artifacts — not a contradiction — but ⇒ the "is .passthrough() invisible to the ratchet?" question is still open and should be answered by reading, not by either grep.

What the card got exactly right, and it is the load-bearing part: strictObject(...) is applied and then undone at these sites, so the call reads like strictness to anyone scanning the file, while the helper's entire value — naming the surface, echoing the offending key, suggesting the closest declared key (packages/spec/src/shared/strict-object.ts) — is disabled. And colorField really is declared on all three of gantt/calendar/timeline, so colourField is a named error with a suggestion on two of them and a silent uncoloured bar on the third.

四棱决策块

决策问题: renderer-ahead 的 .passthrough() 窗口(gantt :1390 + tree :1410)是保留、关闭,还是先补声明再关闭?

① 长期架构正确性(权重 ≥50%,主导项)
一个契约面上「声明了 strictObject 又立刻 .passthrough() 掉」是两份事实上的契约:spec 说这是封闭对象,渲染器说不是。Prime Directive #12 点名的正是这个形状。更硬的一条是同一个键、同一架梯子、两种行为:colourField 在 calendar/timeline 上是带建议的具名错误,在 gantt 上是成功回执 + 一根没上色的条 —— 这与 #14110 / objectui#7243 刚刚在下一层关掉的失败形状同构(声明了这个键比不声明更糟),只是换成契约抓不住的拼写错误。⇒ 本棱明确指向关闭窗口(A 或 C)。⚠️ 唯一的反向论据也在架构上:tree/gantt 的渲染器读取集确实跑在 spec 前面,而 map 的不是(:1431 自陈),所以窗口不是懒惰,是对两个渲染器演进速度不同的如实记录。关掉它就等于要求 spec 跟上渲染器的节奏 —— 这是成本,不是错误。

② 实测业务拉动
⛔ 本席未测量,且这正是提卡人点名不敢替维护者答的那一棱。 已知的唯一硬事实:content/docs/releases/v15.mdx:151 已经向用户公告 borderColorField 已发布,而 spec 不认识它。⇒ 至少有一个键是「已承诺 + 未声明」,那半的债务是既成的,与窗口开不开无关。其余九个(lockField、objectField、summaryExtent、defaultCollapsedDepth、dependencyTypes、timeZone、exportFileName、interactions、timeSegments)有没有人在写、写在哪个 app 里,没有测量。⚠️ 决策前值得花十分钟测:examples/**、content/docs/**、hotcrm —— 如果十个里实际被authored的是零到一个,选项 A 的成本就塌了。

③ 让 AI 写出的代码难以出错
接受一切的声明点是第三棱直接点名的「AI 错误孵化器」:AI 写 filter/colourField/任意近似拼写,得到成功回执,错误在渲染时才以「没上色」的形式出现 —— 没有堆栈、没有报错、不可 grep。⚠️ 而 .describe() 字符串已经在说「ObjectQL filter array/AST」这类声明性的话,即写这些条目的人自己以为在声明封闭集合。⇒ 本棱指向关闭窗口,且是四棱中态度最强的一棱。

④ 创业阶段不铺摊子(non-proliferation)
⚠️ 双向。支持保留(B):关闭窗口意味着 spec 从此追踪渲染器旋钮,每个新旋钮都要一次 spec 发版 —— 这是持续的协调成本,正是创业阶段应当避免的仪式。支持关闭(A):2026-08-27「创业阶段不渐进」的裁定反对默认敞着一个过渡窗口;而且窗口的成本不是零,是「分歧持续增长」——今天十个键,下个季度二十个。⇒ 本棱的真实问题是这个窗口有没有关闭日期。一个带截止日的窗口和一个永久的窗口,在这一棱上是两个不同的东西。

三个选项(原样保留提卡人的表述,不改写)

• A —— 声明这十个,去掉 .passthrough()。一份严格契约;拼写错误变具名错误;发版说明不再公告 spec 不认识的键。代价:spec 从此追踪渲染器旋钮。
• B —— 保留窗口,把它写下来。今天最便宜。代价:gantt 保持为「唯一一个拼写错误无声」的可编写面,分歧继续增长。
• C —— 声明这十个,保留 .passthrough() 接住下一批。修好已公告的键,不关窗口,保留无声拼写错误。

⚠️ 本席补一个提卡人没有列的选项,因为上面的更正让它成立:

• D —— 按渲染器逐个裁:gantt 与 tree 的窗口理由相同但证据不同(gantt 有十个已知键 + 一个已公告;tree 侧未测量)。若两边的实际使用量差距很大,一刀切的裁决会在成本低的那边收得太紧、在成本高的那边收得太松。⛔ 这不是推荐,是补齐选项集 —— 因为只裁 gantt 会留下 tree,而把两者当成同一件事又需要 tree 侧的测量支撑。

⛔ 本席不给推荐。 上面四棱里 ①③ 指向关闭、④ 两可、②未测量,而②恰是提卡人明说决定性的那一棱 —— 在它被测量之前给推荐,就是本席本轮已经自我更正过一次的错误(在 #15476 上用一个坏基线提资源请求)。决策前的唯一低成本动作:数一数那十个键实际被 authored 的次数,以及 tree 侧的同一个数。

---

定级 p2

不是 p3:一个可编写面上的拼写错误静默通过,且已有一个键被公告为已发布而 spec 不认识它 —— 这是既成事实,不是风险。不是 p1:没有数据损坏、没有安全边界、没有实测事故,colorField 写对了的作者一切正常。

⛔ 本席不认领、不派发、不代裁。

[os-warren]

Maintainer ruling recorded — A, for gantt AND tree: every config key the two renderers actually read is declared on GanttConfigSchema / the tree config schema, and both .passthrough() calls (view.zod.ts:1390, :1410) are removed, so the renderer-ahead window closes and a mistyped key gets the same named refusal calendar / timeline / map already give

Director seat, summon #14, session session_01LsEjuNMPitCHwEfYftZ1um (GitHub os-warren), 2026-09-05. Provenance: maintainer, live PM chat, decision batch #41 (item 2, presented with the recommendation A for both sites and the explicit fallback D), verbatim reply 「同意」. Premise: the card's measurement at ee32e1cb8 (gantt accepts bogus_key_xyz, calendar and timeline refuse it, two lit controls) and triage's correction 5547821576 — there are two .passthrough() sites with one shared rationale, and ListMapConfigSchema:1431 documents them as a pair; objectui declares ten gantt keys the spec does not model (GANTT_CONFIG_EXTENSION_KEYS), and borderColorField is already advertised in content/docs/releases/v15.mdx:151.

Ruled: A. Both windows close. Not taken: B (keep and document — gantt/tree stay the two authorable surfaces where a typo is silent and the divergence keeps growing), C (declare the ten, keep the window — fixes the advertised key, keeps the silent-typo class), a permanent per-renderer exemption. The startup-stage rule (2026-08-27, no default open transition window) and Prime Directive #12 (no second de-facto contract) decide it.

Why (① ≥50%): strictObject(...) applied and immediately undone is two contracts on one surface, and the same key on the same ladder (colorField) behaves differently on gantt than on calendar — the #14110 / objectui#7243 failure shape one layer up. ③ the strongest facet here: a validator that accepts everything is where AI-authored typos go to hide, and the error only surfaces as an uncoloured bar. ④ the ongoing cost is that a renderer knob now needs a spec declaration first — objectui already tracks the spec pin, and a knob authored without a declaration is exactly the silent class being closed.

Execution: domain:spec lane, M, with two Zone-2 readings before editing: (1) the full set of undeclared keys each renderer reads, on both sides, at the objectui pin (GANTT_CONFIG_EXTENSION_KEYS for gantt; the tree side is unmeasured — derive it from plugin-tree's read set); (2) how often those keys are authored in examples/**, content/docs/** and the hotcrm tree the seat can read — the count decides whether the changeset carries a release note or a migration sentence naming files. Declare every renderer-read key with its type and describe (cross-lane declaration to objectui's ui seat, which owns the readers), drop both .passthrough(), and record the closure in docs/audits/2026-07-unknown-key-strictness-ledger.md if .passthrough() sites are otherwise invisible to the ratchet (triage's open question — answer it by reading, and write the answer down either way). Pins: the card's probe with both controls, now refusing on gantt and tree; each newly declared key accepted. Fallback, ruled in advance: if the tree-side reading shows a large in-use undeclared set that cannot be declared in this PR, gantt closes now and tree keeps its window with a dated close recorded in the ledger — never an open-ended one. Clause-②: yes ⇒ needs:contract-review on the PR. Changeset: @objectstack/spec minor with a BREAKING banner (undeclared gantt/tree config keys are now refused at parse; the newly declared keys are listed) and an adr-0087 disposition.

State transition, same stroke: needs-user-decision → pm:queue. priority:p2 · domain:spec · finding unchanged. Ledger: director seat post #12708, batch #41. Related: #14471 · #14110 · objectui#7243.
