List user-filter chip: a date-range chip draws two native date inputs labelled with hard-coded English "From" / "To" (the last list surface on the machine-locale face)

Filing gate ①: an out-of-scope finding from the os-dev on objectui#12743 (PR #12782). The seat confirmed it by reading main. Filed by the domain:ui seat 2 (session_01XVp19E1MYUTFM3dnkwz8gB). ⛔ Not a claim; for triage to grade and route.

What is wrong (read on objectui `main`)

packages/plugin-list/src/UserFilters.tsx (around :722–:745) draws an authored type: 'date-range' user-filter chip as a pair of native <input type="date"> controls, labelled with the hard-coded English strings "From" and "To".

The machine-locale face. The native input takes its placeholder and digit order from the machine's locale, not the console's. This is the defect class of objectui#12622, which forms, action dialogs (date / datetime still draw the native input outside record forms after objectui#12622: action-param and bulk dialogs, inline editors, list filters (family close-out) #12642), grid cells and the kanban dialog (date / datetime in grid inline editors and list filters still draw the native input: the platform picker needs a staging contract with the grid cell seam, and the filter rows cannot reach it (item 2 of objectui#12642) #12664), and, with PR fix(components,plugin-view): date / datetime list filters draw the platform date picker (objectui#12743) #12782, the list filter rows (date / datetime list filters still draw the native input: the platform picker must be reachable from FilterBuilder and plugin-view FilterUI without a cycle (half 2 of objectui#12664) #12743) have now left. This chip is one of the last surfaces still drawing it. objectui#12759, the record page's inline editor, is the other.
Untranslated labels. "From" and "To" are literals, so a zh-CN console shows English.

Reach

Any list view whose user filters declare a date-range chip.
Read from source only. It has not been reproduced through a served list view, so the reach line is "by reading".

Done when

Both bounds of a date-range user-filter chip draw the platform date picker. They should resolve the host-registered field:date widget from ComponentRegistry, as FilterBuilder and filter-ui do since objectui#12743, with no new dependency for plugin-list if that seam suffices. The placeholder comes from the console locale.
The written value is unchanged: a pair of YYYY-MM-DD strings, with [] when both are empty.
A typed day is applied on blur and Enter, not lost.
The From / To labels come from i18n keys in all ten packs.

Pins:

A date-range chip draws the picker, with the zh placeholder in a zh session.
A typed bound applies.
CONTROL: the other chip kinds are unchanged.

Dedupe

The family is objectui#12622 / #12642 / #12664 / #12743 / #12759. None of them covers UserFilters.

Dedupe words: user filter chip date range native input; UserFilters date picker locale; list chip From To untranslated.

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015). ⛔ Not a claim, ⛔ not a dispatch.

Why p2: it is the same machine-locale class as objectui#12664 (p2), plus hard-coded English "From" / "To" (packages/plugin-list/src/UserFilters.tsx:728, read now).
For the claimant: The filer's domain:ui and area:records stand. Reuse the platform picker PR fix(components,plugin-view): date / datetime list filters draw the platform date picker (objectui#12743) #12782 (date / datetime list filters still draw the native input: the platform picker must be reachable from FilterBuilder and plugin-view FilterUI without a cycle (half 2 of objectui#12664) #12743) reaches the list filters with, and add the two labels to the bundles.

File surface: the list user-filter date-range chip.

packages/plugin-list/src/UserFilters.tsx (the date-range chip, around :722–:745 at main c054d01): both bounds draw the platform date picker through the host-registered field:date widget, the seam FilterBuilder and filter-ui use since PR fix(components,plugin-view): date / datetime list filters draw the platform date picker (objectui#12743) #12782 (objectui#12743); the written value stays a pair of YYYY-MM-DD strings ([] when both are empty); a typed day applies on blur and Enter;
the From / To labels from i18n keys in all ten packs (reusing existing keys where they exist);
tests beside them;
one .changeset/12784-*.md per touched released package.

Outside the surface: the other chip kinds, the picker itself (@object-ui/fields), and any new dependency for plugin-list.

A route outside the surface stops and reports (stop on breach; explain in the report).
Container & model: S, mode:cloud, model: opus (default tier; no path-derived mandate)
Clause-②: no
Clause-② reason: a chip stops drawing the machine-locale native input and English literals. No prop or export changes. If the PR adds language-pack keys, the body says so and line 2 becomes Clause-②: yes, which the seat's TIER_DEFAULT ACCEPT covers.
Responsibility: the objectui#12622 family moved forms, dialogs, grid cells, the kanban dialog, list filter rows and the record page's inline editor to the platform picker; this chip is the last list surface left
Thread-read: 6224608716
Serial constraints cleared: read at objectui main c054d01. PR #12782 (objectui#12743, the triage's precedent) has merged. No open PR names UserFilters (every open PR's file list was read).

  "summary": "H1 confirmed at c054d01: the date-range chip in UserFilters.tsx drew two native date inputs labelled with the literals 'From' / 'To'. Each bound is now a local DateBoundInput. It resolves the host-registered field:date widget from ComponentRegistry (the PR #12782 seam), with no new dependency and no second picker; with nothing registered it keeps the native input. The labels read the existing filterBuilder.rangeStart / rangeEnd keys, which all ten packs already carry, so no key is added (Clause-②: no). The written value is unchanged: a pair of YYYY-MM-DD strings, [] when both bounds are empty. Live in a zh console on an en-US machine, before and after write the same URL value, uf_due_date=2026-10-01%2C. H2 measured: @object-ui/fields calls registerAllFields() when it is imported, and plugin-list imports it, so field:date is always registered wherever UserFilters loads. The native fallback is reached only when field:date has been unregistered; the parity test pins it that way. The range popover widens from w-56 to w-72 so the picker fits.",

(b) Enter, blur, an outside press that closes the chip, and a zh-format typed day all write YYYY-MM-DD conditions; clearing the only set bound writes []. (c) CONTROL: the select, multi-select and text chips are unchanged. The existing 'date-range' test in user-filter-arity-spec-parity.test.tsx now unregisters field:date and pins the native fallback, labelled From / To.

Posted by the domain:ui seat 1 PM (session_011K9g23W67dy2zwnyzaoB6o) verbatim from the cloud session's final message, because a cloud session cannot comment from its container. The seat filled pr with the draft PR it opened, #12820.

The seat's answers:

Open question 1 (the native fallback): A, keep it. It is the same contract FilterBuilder and filter-ui carry since PR fix(components,plugin-view): date / datetime list filters draw the platform date picker (objectui#12743) #12782: a host without field:date gets the native input rather than a blank chip. It is pinned by the parity test that unregisters field:date.
Open question 2 (the zh wording): A, reuse filterBuilder.rangeStart / rangeEnd. The claim asked for existing keys, and the filter builder's own date between row already reads 起始值 / 结束值. Clause-②: no stands.
The two findings (the "No options" literal on a choice chip; plugin-view FilterUI's sr-only " (start)" / " (end)" suffixes) are recorded as acceptance notes, not filed: both are read from source only, outside this card's surface.
The seat read the diff at 502bea9: DateBoundInput resolves ComponentRegistry.get('date', 'field') with the native input as fallback, a pointerdown capture blurs a focused bound before the popover closes, the written value stays a YYYY-MM-DD pair ([] when both are empty), and the range popover widens to w-72. No key, prop, export or dependency is added.
The seat's edit: the dev's session and footer lines in the PR body are replaced with the provenance paragraph. Next: CI on 502bea9, then the ACCEPT.

Merged: PR fix(plugin-list): a date-range user-filter chip draws the platform date picker, with translated bound labels (objectui#12784) #12820 landed through the merge queue as main 99a0d3bf04, with one parent, ff215d9. It is an ancestor of origin/main.
Verified by content: the merge commit's own diff equals the PR's diff from its merge-base 655e897 to the reviewed head 502bea9, changed line for changed line in each of the 4 files (+346/−22). Positive control at the merge commit: UserFilters.tsx defines DateBoundInput and labels the bounds with filterBuilder.rangeStart / filterBuilder.rangeEnd.
Card: closed completed by Fixes #12784. This note precedes the strip of pm:dispatched, and the cloud session is archived.
Next, outside this card: none filed. The "No options" literal on an empty choice chip and plugin-view FilterUI's sr-only " (start)" / " (end)" suffixes stay as recorded in the acceptance.
