Record create: a date typed in an invalid form (13/45/2026) is silently dropped, and the record saves with an empty Due Date and a success toast

Found in the 18.3.0 release-candidate browser walkthrough (wave anchor #27377, card W3-UX), at framework main @ c4c515ad, Console built in-repo from the same commit.

Repro (fresh boot)

Boot examples/app-showcase with --seed-admin and sign in as admin. Viewport 1440×900.
Open Showcase → Tasks and click New.
Enter Title Walkthrough task and pick a Project.
Type 13/45/2026 into Due Date. The input shows exactly that text.
Click Create.

Expected

The date field is marked invalid ("Enter a valid date") and the dialog stays open, as it does for a missing required field.

Actual

The toast says Task "Walkthrough task" created. The saved row has due_date: null (GET /api/v1/data/showcase_task/ID). The typed value disappears with no message, so the user believes the date was saved.

⛔ Not a claim.

Read fresh. An invalid typed date (13/45/2026) on record create is silently dropped. The record saves with an empty Due Date and a success toast. A silent drop of an authored value: p2.
Mark an unparseable date invalid through the form's existing field validation, as a missing required field is. No silent null.
bug, pm:queue.

Session: session_01Utp6CY2n1JmZZKrHgtp9jC (seat; implementation by a card thread, mode:thread)
Account: os-bill
Branch: claude/project-thread-t6m105 (the card thread's harness push branch, self-reported — the measured platform exception to claude/issue-N-slug)
Worktree: objectstack-issue-27483
Domain: domain:ui
Seat: domain:ui#2
File surface: ui/packages/fields/src/widgets/** (date picker + widget types), the form renderer that mounts widgets (ui/packages/components/src/renderers/form/form.tsx and/or ui/packages/plugin-form/src/ObjectForm.tsx), i18n only if a key is missing, tests beside, a changeset (stop on breach; explain in the report)
Container & model: M, mode:thread, model: TIER_DEFAULT (dispatch-gates --tier: no path-derived mandate), effort: high
Clause-②: yes (widening) — corrected by the seat from the diff: the new optional onInvalidInputChange key on FieldWidgetComponentProps, exported from @object-ui/fields; owes a TIER_DEFAULT declaration review at the final head
Metadata-protocol: none (expected; the dev measures from the diff)
Responsibility: ui/packages/fields date picker + the form renderer's validation | none (the form's required-field validation does not see the picker's bad text) | every user typing a date on a create/edit form, today
Thread-read: 6496267646
Premise: holds — on origin/main ee9a8d6e DatePickerField sets only local badText for an unparseable date and never reports it to the form (no outbound validity channel in FieldWidgetComponentProps)
Serial constraints cleared: none on fields/src/widgets/date-picker/**; ObjectForm.tsx / form.tsx are shared with this seat's #27247 (different regions: submit bar vs field validation): ordinary concurrency, later lander merges main

Dispatch order: /mnt/project-files/ui-seat2/dispatch-27483.md in the Claude Code project (not on GitHub); its ruling section quotes the triage/maintainer text above verbatim.

The form renderer (components form.tsx) holds the message per field and refuses through a first rules.validate entry, invalidInput, triggered at once on report; withdrawal clears only that error; stripRegisteredFieldProps forwards the callback to date/datetime only. time is a native input with its own path, untouched.
