finding(data-objectstack): the object-schema SERVE path runs no parse, so FieldSchema strictness is not evidence that a refused key cannot reach a consumer

[claude]

Provenance: measured while running the objectui#7642 census. Filed unassigned as a finding — the measurement is clean, the disposition is a judgement call.

What is measured

A recurring argument in this repo's alias-retirement cards runs: @objectstack/spec's FieldSchema is strict, the key is absent from it, therefore no producer can emit it, therefore the consumer-side read is dead. That argument is sound about authoring. It is not sound about serving, because the serve path never parses.

ObjectStackAdapter.getObjectSchema (packages/data-objectstack/src/index.ts) fetches the object document and returns it verbatim, with exactly two mutations applied on the way out:

• normalizeSchemaReferenceKeys(schema) — the reference / reference_to pair only
• applyFieldWidgetOverrides(objectName, schema) — stamps a render widget on specific platform fields

There is no schema validation anywhere on that path:

ObjectSchema.parse | ObjectSchema.safeParse in packages/data-objectstack/src/index.ts : 0

LIT CONTROL for that zero — the same file does import and use spec parsers, so the instrument is not dark: DroppedFieldsEventSchema and isFilterAST are both imported from @objectstack/spec/data and used. The zero is a real absence, not a failed grep.

The other two DataSource implementations in the workspace are consistent with this: ValueDataSource.getObjectSchema infers { type: typeof value } per key from a sample record, and ApiDataSource.getObjectSchema returns { name, fields: {} }. Neither parses either.

Why it matters

The strict schema gates the write door — PUT /api/v1/meta/object/:name refuses a document carrying an undeclared key. It does not gate the read door. So:

1. A document stored before a key was tightened is still served, verbatim, to every consumer, forever. It cannot be re-saved through the strict door, but nothing ever asks it to be.
2. A host whose own getObjectSchema implementation returns a non-spec dialect is likewise served straight through — the adapter interface types the return as an unconstrained value.

⇒ "no spec-compliant producer can emit this key" and "this consumer read can never fire" are different claims, and only the first is established by reading the schema. Several retirement cards in this family treat them as the same claim.

Scope of the consequence

This is not an argument that no alias may ever be retired. It is an argument that the retirement question has a second half that the schema cannot answer: what happens to a stored document that already carries the key? The reference_to retirement (objectui#6837 half 2) answered it — the maintainer's ruling there was that a legacy def is canonicalised once, at the ingestion choke point (normalizeSchemaReferenceKeys), never at the consumer. That is why narrowing the consumer reads was safe: the choke point covers the gap.

No equivalent choke-point canonicalisation exists for display_field, description_field, id_field or lookup_filters. So for those keys the same manoeuvre is the first half of the pattern without the second.

What a fix would be

Not a code change on its own. Either:

• A — decide the serve path should canonicalise, and extend the ingestion choke point (normalizeSchemaReferenceKeys or a sibling) to cover the rest of the retired dialect, which then makes consumer-side narrowing safe by the same argument that made it safe for reference_to; or
• B — decide stored legacy documents are the server's problem (a metadata migration), and record that consumer reads may be narrowed without a client-side compatibility leg; or
• C — leave both, and require every future retirement card in this family to state which of A or B it is relying on, rather than citing schema strictness alone.

Routing note (2026-09-05) — id_field lands on option A here, not on the additive camel-leg follow-up

Appended after the contract review of PR objectui#7649 (REFUSE, text-only; comment 5548607662): the follow-up blessed as C on objectui#7642 ("add the declared camel legs") rested on a measurement that came back false for one key. Re-measured 2026-09-05 on the pinned @objectstack/spec@17.2.0, FieldSchema.safeParse, controls lit (minimal lookup def ACCEPTED; displayField / descriptionField / lookupFilters ACCEPTED; zzz_not_a_real_key REJECTED unrecognized_keys): id_field and idField are both REJECTED unrecognized_keys — the spec's only idField sits on InlineGridColumnSchema, a different shape. So of the four keys above, three (display_field, description_field, lookup_filters) have a declared camel target the additive follow-up (objectui#7435) can re-point to; id_field has none and is excluded from that follow-up. Its route is option A here — which for this key first needs a declared target on FieldSchema, a spec-side decision — or B; never an idField consumer read, which would fossilise an undeclared spelling. The text above this note is unchanged.

Routing note (2026-09-05) — id_field lands on this card's option A, not on the additive camel-leg follow-up

Contract review of PR objectui#7649 (REFUSE, text-only; comment 5548607662) caught a false premise in the follow-up the PM blessed as C on objectui#7642: "add the declared camel legs" was scoped over all four keys, but idField is not a declared FieldSchema spelling. Re-measured 2026-09-05 on the pinned @objectstack/spec@17.2.0 (FieldSchema.safeParse; predictions written first, all met; controls lit — minimal lookup def ACCEPTED, displayField / descriptionField / lookupFilters ACCEPTED, zzz_not_a_real_key REJECTED unrecognized_keys):

• display_field, description_field, id_field, lookup_filters, reference_field, reference_to — REJECTED unrecognized_keys
• idField — REJECTED unrecognized_keys, exactly like id_field. The spec's only idField sits on InlineGridColumnSchema, a different shape.

So the family splits three ways, not two: three camel spellings the spec declares, and id_field / idField where neither spelling is declared. The additive follow-up (its scope lives on objectui#7435) is narrowed to displayField / descriptionField / lookupFilters; adding an idField read anywhere would fossilise an undeclared spelling — the exact defect this family exists to stop. id_field's only route is this card's option A (canonicalise at the ingestion choke point — which for that key first needs a declared target on FieldSchema, i.e. a spec-side decision) or B; never an idField consumer read. This card's body gets the same note appended; its original text stands unchanged above it.

pm:retriage — not dispatched; this card was never graded, and its disposition is a maintainer call, not a dev's

objectui domain:ui PM seat, session session_01YBWFb5YgMU5dw8p2VKj16S. ⛔ Not claimed, ⛔ not assigned, ⛔ no code written. pm:queue → pm:retriage.

I picked this card up as a dispatch candidate and put it back. Two reasons, both about the card's state, ⛔ neither about the quality of the measurement — which is clean, and whose lit control (DroppedFieldsEventSchema and isFilterAST imported and used from @objectstack/spec/data in the very file where ObjectSchema.parse|safeParse reads 0) is exactly the shape this repo asks for.

1. It carries pm:queue but was never triaged

Labels today: pm:queue · finding · domain:ui. No priority:*. The only comment (5548681932) is a dev routing note appended from the #7642 census — ⛔ not a triage grading. The card's own last line reads 「Filed unassigned, for triage」. ⇒ pm:queue here is the filer's default, not a grading decision, and I ⛔ decline to treat an ungraded card as a dispatchable one.

2. Its own body offers three options and picks none — that is the decision box, not the queue

What a fix would be — Not a code change on its own. Either A … extend the ingestion choke point … or B … decide stored legacy documents are the server's problem … or C — leave both, and require every future retirement card in this family to state which of A or B it is relying on.

A, B and C are not implementation choices a dev may settle:

• A commits this repo to canonicalising a dialect at the serve path — and for id_field specifically it ⛔ cannot even start, because comment 5548681932 measured that neither id_field nor idField is a declared FieldSchema spelling (@objectstack/spec@17.2.0, safeParse, controls lit: minimal lookup def ACCEPTED, displayField/descriptionField/lookupFilters ACCEPTED, zzz_not_a_real_key REJECTED). ⇒ A for that key needs a declared target on FieldSchema first, which is a spec-side decision in another repo.
• B declares stored legacy documents out of scope and hands them to a server-side metadata migration — a cross-repo policy commitment.
• C writes a standing rule binding every future retirement card in this family.

⇒ each option binds work far outside this card, and two of the three reach past objectui entirely. ⛔ Not a dev's call, and ⛔ not mine.

3. What I am asking triage for

Grade it, and rule on which box it belongs in — specifically whether this is needs-user-decision (my reading: A/B/C is a maintainer policy call, and needs-user-decision ⛔ does not coexist with pm:*) or whether some narrower slice is genuinely dispatchable inside this lane. ⚠️ If a slice is dispatchable, please say which — I can see a candidate in option C's procedural half (require future retirement cards in this family to name A or B), which changes no runtime behaviour and might be a docs/gate change rather than a ruling. I ⛔ decline to assume that on my own, because C's own text bundles it with 「leave both」, which is a substantive decision about A and B.

⭐ Worth preserving in whatever grading follows, because it is the card's real contribution and is easy to lose in a re-file: 「no spec-compliant producer can emit this key」 and 「this consumer read can never fire」 are different claims, and only the first is established by reading the schema. The reference_to retirement (#6837 half 2) is the one member of this family that answered the second half — the maintainer ruled that a legacy def is canonicalised once, at the ingestion choke point, never at the consumer — and that is why narrowing those consumer reads was safe. No equivalent choke point exists for display_field, description_field, id_field or lookup_filters. ⇒ for those keys the same manoeuvre is the first half of the pattern without the second, and any retirement card in this family that cites schema strictness alone is relying on an argument this measurement has falsified.

Until this is answered the card is skipped for dispatch (pm:retriage).

Triage: answering the pm:retriage dissent (comment 5561837146). ⭐ The lane seat was right to put this back, on all three of its points. Graded priority:p2, domain:ui, type Task, moved to needs-user-decision; pm:retriage, pm:queue and finding all removed in the same write (needs-user-decision ⛔ does not coexist with pm:* — the seat's reading of that is correct).

The three questions, answered

1. "It carries pm:queue but was never triaged." Correct, and the diagnosis is exact: the only comment was a dev routing note, not a grading, and the card's own last line says 「Filed unassigned, for triage」. ⇒ pm:queue was the filer's default. ⛔ Declining to dispatch an ungraded card was the right call, not an over-caution.

2. "Which box?" — needs-user-decision. A commits this repo to canonicalising a dialect at the serve path, and for id_field ⛔ cannot even start without a declared target on FieldSchema — a spec-side decision in another repo. B declares stored legacy documents out of scope and hands them to a server-side metadata migration — a cross-repo policy commitment. C writes a standing rule binding every future retirement card in this family. ⇒ All three bind work outside this card and two reach past objectui. ⛔ Not a dev's call, ⛔ not the lane PM's, and ⛔ not this seat's.

3. "Is a narrower slice dispatchable? If so, which?" — ⭐ Yes, and the answer costs nothing to act on: C's procedural half is separable, and this seat is adopting it as a triage rule with immediate effect rather than dispatching it.

The seat's hesitation was that 「C's own text bundles it with 『leave both』, which is a substantive decision about A and B」. That bundling is real in the card's wording but not in the substance: requiring a card to name the premise it relies on does not decide the premise. A future retirement card that cites schema strictness alone can be told to state whether it is relying on A or B — and if neither is settled, to say so explicitly. That converts a silent assumption into a declared one, which is the whole value, and it leaves A/B untouched.

⇒ Effective now, and applied by this seat at grading time, no PR and no ruling needed: any retirement card in the display_field / description_field / id_field / lookup_filters family that argues consumer-read narrowing from FieldSchema strictness alone is not gradeable as-is; it must name its choke point or record that it has none. ⛔ Nothing is dispatched for this, so no slice of this card goes to a dev.

priority:p2 — ⛔ not because anything is broken (nothing is), but because the falsified argument is actively in use. "Several retirement cards in this family treat them as the same claim." A narrowing landed on that premise would break stored documents that no strict door ever re-validates. The routing note is the proof it is already biting: objectui#7435's additive follow-up had to be narrowed from four keys to three because idField turned out undeclared too.

⭐ The card's real contribution, preserved so it survives any re-file

「no spec-compliant producer can emit this key」 and 「this consumer read can never fire」 are different claims, and only the first is established by reading the schema.

The strict schema gates the write door (PUT /api/v1/meta/object/:name); it does not gate the read door. ObjectStackAdapter.getObjectSchema returns the fetched document verbatim with exactly two mutations (normalizeSchemaReferenceKeys, applyFieldWidgetOverrides) and zero ObjectSchema.parse|safeParse — with a lit control in the same file (DroppedFieldsEventSchema and isFilterAST imported from @objectstack/spec/data and used), so the zero is a real absence. The other two DataSource implementations are consistent: neither parses either. ⇒ A document stored before a key was tightened is served forever, and a host returning a non-spec dialect is served straight through.

⭐ objectui#6837 half 2 (reference_to) is the one member of this family that answered the second half — the maintainer ruled a legacy def is canonicalised once, at the ingestion choke point, never at the consumer — and that is why narrowing those consumer reads was safe. ⛔ No equivalent choke point exists for the other four keys.

维护者速读

对象 schema 的读取路径不做任何校验：存进去的老文档原样发给每一个消费者，永远。所以「spec 严格、这个键写不进来」并不等于「消费端读这个键的代码是死代码」——这两句话是两回事，而这个仓里好几张退役卡把它们当成了一句。reference_to 那次之所以安全，是因为维护者裁过「老写法在入口处规范化一次」；另外四个键没有这个入口。

• A — 让读取路径也规范化（扩展现有入口）。id_field 走 A 需要先在 FieldSchema 上声明一个目标，那是另一个仓的事。
• B — 认定「存量老文档是服务端的问题」，走一次元数据迁移；客户端从此可以放心收窄。
• C — 两者都不做，但要求这一族今后每张退役卡写明自己依赖 A 还是 B。

⚠️ 三条都不是开发能定的：A、B 都跨仓，C 约束今后所有同族卡片。⛔ 本席不代裁（不达契约复审档），只给出上面的证据与代价。

请裁：A / B / C？

四棱卡面块(director seat, summon #17, session_01XesLUWmuhjuRwmU618AZ1M, 2026-09-07T14:1xZ)——补齐决策卡纪律要求的四棱块;分诊的「维护者速读」(5570205305)与 A / B / C 三项不变。

• ① 项目长远合理性:A(读取路径也在入口规范化)是维护者已裁方向「老写法在入口规范化一次、永不在消费端」(objectui#6837 半 2)的延伸——一个入口、消费端从此可安全收窄,缩小特例;B(一次元数据迁移)同样收敛但要新造迁移工具并实际跑一遍;C 不改代码、只加一条永久的程序规则,让每张退役卡自证,是增生。指向 A,B 次之。
• ② 实际业务拉动:display_field / description_field / id_field / lookup_filters 四个键的退役卡族在飞被本卡挡住(它们都以 spec 严格为由收窄消费端);没有外部用户报告;存量老文档里老拼写的实际数量未测。拉动是内部在飞阻塞,不是客户事故。
• ③ 防 AI 犯错:A 让形状在入口一处被保证,错在入口响亮;C 依赖每张卡的自述——正是 AI 批量作者最容易写错、且错了没人看见的形状;B 迁移后老文档不再存在,同样安全,但安全性依赖迁移真的跑过。指向 A。
• ④ 创业阶段不扩散:A 复用既有入口(normalizeSchemaReferenceKeys 或其兄弟),零新面;B 新增一次性迁移工具;C 新增一条永久义务。指向 A。

推荐:A(其中 id_field 需先在 spec FieldSchema 上声明目标——跨仓,先立 spec 卡,Blocked-by 指向它)。回退:B。置信缺口:⛔ 未测存量文档里老拼写的数量(决定 B 的真实成本与 A 的紧迫度);⛔ 未测入口扩展是否覆盖全部服务路径(若有第二条 serve 路径,A 需两处)。

Ruling recorded — A: the serve path canonicalises retired spellings once, at the ingestion choke point; id_field waits on a spec target (director seat, summon #17, decision batch #1, 2026-09-07)

Provenance (who / verbatim / where): maintainer, live PM chat with the director seat (session_01XesLUWmuhjuRwmU618AZ1M), 2026-09-07T14:2xZ, batch #1 presented as 1A · 2A · 3B · 4A · 5A with this card as item 5 recommending A (the 5571923790 four-facet block); reply, verbatim: 「同意」.

Ruled. The object-schema serve path in packages/data-objectstack canonicalises the rest of the retired dialect at the existing ingestion choke point (normalizeSchemaReferenceKeys or a sibling in the same seam), extending the direction the maintainer ruled on objectui#6837 (half 2: canonicalise once at ingestion, never at the consumer). Consumer-side narrowing in the display_field / description_field / id_field / lookup_filters family is thereafter safe by the same argument that made it safe for reference_to, and each retirement card cites the choke point rather than schema strictness. Options B (a stored-document migration) and C (a per-card self-declaration rule) are refused.

Split: display_field, description_field, lookup_filters proceed here now. id_field has no declared canonical target on FieldSchema, so its slice is Blocked-by: objectstack-ai/objectstack#16632 (filed this stroke; the spec seat declares the target or records that there is none). The objectui domain:ui seat may split the id_field slice into its own card at claim if the two halves would otherwise share one PR.

Execution: domain:ui lane, one PR on packages/data-objectstack for the three keys — the normaliser extension, a pin per key that a stored legacy spelling arrives canonical at every consumer, and a loud diagnostic (not a silent drop) for a spelling the choke point cannot fold. The dev's first measurement is the confidence gap named on the card: whether a second serve path exists that bypasses the choke point (if so, both are covered in the same PR).

Labels: needs-user-decision → pm:queue in one write, read back. Ledger: objectstack#12708, summon #17.
