Object fields: repeater / composite cannot declare typed sub-fields, so they are untyped JSON in forms and flows #25681
Description
Ruled: 6386744473 · batch #12 item 4 · letter b · 2026-10-24T16:30:45Z (object-level repeater / composite stay untyped JSON; docs + FieldType description + lint; a typed list is a child object; no sub-field member)
Category: ② maintainer decision / feature gap.
Need
repeater (and composite) are listed in FieldType as "embedded sub-object array with declared sub-fields", but an object field has no member to declare those sub-fields: FieldSchema refuses fields / subFields, and objectui's structured cell says so explicitly ("the spec's FieldSchema has no sub-field member for either type"). So a repeater on an object is an untyped JSON array: the form maps it to field:grid with no columns, sub-values get humanized keys instead of labels, there are no per-column types, options, required flags or translations, and nothing can validate or address one row.
Who benefits / scenario: business apps that want a short typed list on a record without a separate object. hotsrm (objectstack-ai/hotsrm#38, PR objectstack-ai/hotsrm#46) designed a supplier audit with checklist (item, score, note) and findings (finding, severity, requirement, linked SCAR) repeaters, and plans an 8D steps repeater (date, owner, attachment per D1–D8) for the supplier portal in v0.6. Without declared sub-fields none of these is usable in the form, and a flow cannot write back to one row (e.g. link the SCAR raised from a finding).
What hotsrm does regardless
Findings are a child object (srm_supplier_audit_finding, master_detail) and per-item checklist scores stay in an attached scoresheet; that stays even if repeaters gain sub-fields, because findings need their own record identity for SCAR links and counts. The 8D steps repeater is the remaining consumer that would use the feature.
Decision asked
Either (a) add a declared sub-field member (label, type, options, required, i18n keys) to (not chosen, ruling 6386744473); or (b) state in the repeater / composite object fields, rendered by the form gridFieldType description and docs that object-level repeaters are untyped JSON and that a typed list should be a child object, and refuse or lint a repeater that expects columns. ← ruled b.
Who acts: maintainer ruling, then the spec seat (packages/spec data/field, docs, one lint rule); objectui form grid: no work.
Dedupe: repo:objectstack-ai/objectstack repeater in:title,body → 0 hits (open + closed); repo:objectstack-ai/objectstack subFields composite → 0 hits.

Ruling: batch #12 item 4 · letter b · maintainer 「25681 b」 2026-10-24T16:30:45Z
b = 不给对象字段的
repeater/composite加子字段声明；明确写下「对象级repeater/composite是无类型 JSON，要带列的列表请建子对象（master_detail）」，并对期望列的 repeater 做 lint/拒收。协议不新增面。裁决含义（给执行席）：
packages/spec/src/data/field.zod.ts的FieldType描述改口：composite/repeater是无类型 JSON 容器，CMS 血统（≈ Strapi component / ACF repeater）；不承诺子字段。content/docs字段类型页同句，并指向子对象 + 内联表格的做法（Salesforce / Dynamics / ServiceNow / Odoo 的主流形态）。repeater/composite且声明了fields/subFields/columns之类的键 ⇒ 报错；表单视图view.zod.ts的fields子行与 Studio 元数据表单（field.form.ts）不在此列，照旧。steps，届时按子对象建模。hotsrm 现有的子对象做法（srm_supplier_audit_finding）即是推荐形态。工作量：S（spec 描述 + 文档一句 + 一条 lint 规则）。

(1) FieldType comments (field.zod.ts:95-104) now say object-level composite / repeater are untyped JSON containers of CMS lineage with no declared sub-fields, and a typed list is a child object (master_detail, inlineEdit: 'grid'). (2) MEASURED: FieldSchema is strict and already refused fields / subFields / columns (and schema, items, properties, itemFields, of, children) at parse, but the message named only the key. Three FIELD_KEY_GUIDANCE rows (authoring-key-lint.ts) now make that refusal name the child-object route; the columns row also names lookupColumns / relatedListColumns / inlineColumns. (3) New lint rule field/embedded-sub-fields (error) in lintDataModel; its docblock and os explain state it reaches only the unparsed doors (os lint on a raw config, defineStack strict:false, which measured ACCEPTS and keeps the key, and the metadata-generation rubric) - the security-owd-alias posture.
