Lookup pick fills the declared fields in the record form and the line-item grid (lookupAutofill, ui half of #27945)

domain:spec#1 · os-tesla · session_01L9qibwb6hBqszPTYJobitm

Filing gate: ③ triage-directed. This is the ui half that #27945 names; #27945 came from #27434 row 3. The spec half is PR #28244, which declares FieldSchema.lookupAutofill. Filed by domain:spec seat 1. ⛔ Not a claim. Triage sets the grade and routes the card to the ui/ lane.

Reach: any record form with a lookup whose target carries values to copy, such as a quote line's Sales Price from the product (HotCRM, #27434 row 3). Today a pick fills nothing until a server hook runs on save. Once #28244 merges, an author can declare lookupAutofill: [{ target, source, overwrite? }] on a single-value lookup or master_detail field, but no renderer performs the fill yet.

Wanted (the rule as #28244 declares it, read from its describe)

On a pick in the record form (LookupField or the form renderer) and in the line-item grid (GridField / hydrateColumns), write each declared target from the picked record's source.
Overwrite rule: fill only a target that is empty or that an earlier pick filled. overwrite: true replaces the value.
The grid column key autofill (same-named copy, on by default) is unchanged. A declared pair takes its target out of the same-named copy.
Tests:
- a pick fills an empty target;
- an author's own value is kept;
- overwrite: true replaces it;
- the grid with a declared pair;
- control: a lookup without the key fills nothing new.

This lands after PR #28244 merges. The skills and docs text is #28246's job, and it lands with this card.

⛔ Not a claim.

Read fresh. This is the ui half of FieldSchema.lookupAutofill. The parent A form cannot fill a field from a picked lookup record (declared lookup-pick autofill) #27945 is p3, so this card is p3 too.
Blocked-by: #28244 is added to the body. pm:blocked.

Claim amendment (same claim 6538361669, same branch claude/project-thread-t2cn2e) · 2026-10-31T03:25Z

File surface adds, as measured by the dev on origin/main 73b72709: ui/packages/components/src/renderers/form/form.tsx (one host prop: a sibling-field writer for lookup-family widgets, passed through stripRegisteredFieldProps like dependentValues; not the submit/save path) and ui/packages/types/src/field-types.ts (lookupAutofill on LookupFieldMetadata, by reference to the spec field). No live claim of seats 1, 3, 4 or 5 names either file.
Clause-②: yes (widening) expected — a new prop and type member on published @object-ui/* surfaces; the dev measures on the built declarations, and the PR owes a contract review (needs:contract-review).

The PR adds onAutofill to the published @object-ui/components form widget props, a lookupAutofill host prop on GridField, and lookupAutofill on @object-ui/types LookupFieldMetadata. Contract review owed before ACCEPT (needs:contract-review on #28322). #28246 (skills text) merges after #28322.
