[Direction · v18] Retire the flat `object`/`filter` data-binding family — `dataSource` as the single data-binding door (re-anchor of the deleted #6590 tracker)

[claude]

Filed by the triage seat (session session_01Kktexqp6uVuFMztvvTMf3V, 2026-08-24 concentration round) to replace the unresolvable tracker #6590 (404 — deleted/transferred/converted, undeterminable) that two live packages/spec/src/ui/component.zod.ts sites still anchor a v18 decision to (measured in #11269 at 8da636880, lines ~137 and ~1894).

The held question (direction B)

Retire the flat object/filter data-binding family on components and make dataSource the single data-binding door. The two source sites record the standing intent: "v18 as #6590 — not rejected" and "tracked as #6590 for v18".

This is a v18-major ADR-0087 removal-train candidate; it rides the breaking window, not a normal queue.

Restart-when: the v18 major development cycle opens (first v18 changeset-major accepted on main), or the ADR-0087 v18 removal batch is assembled — surface this card into that batch
Restart-touch: packages/spec/src/ui/component.zod.ts

Refs: #11269 (the dead-pointer finding; its queued fix re-points the two citations at THIS card) · #9249 (whose landing note could not be delivered to the 404).

Delivering the landing note that #9249 owed this direction — undeliverable to #6590 because that tracker 404s (measured in #11269), now landed here since this card is #6590's re-anchor.

The ruling that created this obligation

The triage ruling on #9249 (2026-08-17) closed with a sequencing note:

Sequencing note: an element-grain verdict here subsumes the element:form half of #6590 (v18 direction card, on hold) — leave a note there when this lands rather than expanding scope.

#9249 landed as PR #11244 (merged 2026-08-23T07:20:45Z, 72f5cab9). Its "Fences honored" section recorded the obligation as still owed:

#6590: not expanded; its element:form subsumption note is a PM-side landing step. That card remains open.

#6590 was found dead (404) during the landing sweep, and the note was recorded undeliverable in #11269 instead:

the #6590 subsumption note could NOT be delivered — that issue returns 404 (deleted/transferred/converted; semantic search was void at measurement time, positive control failing). The subsumption content and the dangling source refs (component.zod.ts:137, :1894) are recorded as finding #11269 for triage to re-anchor.

The subsumption content, delivered

PR #11244 retired element:form whole, at element grain (all six ElementFormProps keys — object, fields, mode, submitLabel, onSubmit, aria — became retiredKey() tombstones; PageComponentType dropped the enum member). Its verdict:

Verdict: dead at element grain. Declared with a full form contract, validated by lint, rendered by nothing in any repo, with the replacement (the object-bound object-form block, #7751) live and named by the Studio exclusion. Premise valid; retirement proceeds.

That followed #9220, which had already retired element:filter the same way (element:filter is the card #9249's own body names as the direct precedent: "Found while retiring element:filter at element grain (#9220)").

So both named element carriers of the flat object/filter data-binding family are now gone — neither element:form nor element:filter exists as a schema any more for direction B to retire keys from.

What's left of direction B

The remaining scope is the ElementDataSourceSchema-side flat keys on element:record_picker (object, filter, sort, limit) — the last live carrier. PR #11244 updated that carrier's own docblock (component.zod.ts, ElementRecordPickerPropsSchema) to record the two retirements and what they leave behind:

Direction B — retiring the whole flat family and making dataSource the single data-binding door — was NOT dropped: it is a cross-element decision (element:form / element:filter carried the same flat object when it was recorded), tracked as #11509 for v18, and A does not block it. Both of those elements have since retired WHOLE at element grain (#9220 / #9249, ADR-0049 — no renderer for either ever shipped), so this element is the flat family's last carrier; when B lands these two retire alongside object / filter under ADR-0087, together.

(That citation now reads #11509 — re-pointed by #11269's fix.)

No new decision is being made here; this comment only carries the note the #9249 ruling asked for across to its resolvable home.
