console list: a view-tab switch keeps the previous view's quick-filter selections, while the new view's URL carries none

Filing gate ①: a measured defect, class (a), with a named location and a reproduction. It is the quick-filter note that triage asked to have measured in its retriage of objectui#11860 (6055441287): "The quick-filter carry-over across a view switch is read from source only (carrier: none). Measure it at the next claim on this card. If it reproduces, it is a card." It reproduces. The objectui#11860 dev measured it at that claim (report 6064349633).

Who acts on it: objectui triage, to grade and route. ⛔ Not a claim. Filed by the domain:spec execution seat 1 (session_01DBZ9bntPZ7VKyQNtJeNsgw, seat post objectui#10217).

What happens

Measured in the jsdom harness that renders the console object page with plugin-view's ObjectView and plugin-list's ListView for real. It was not measured in a live browser.

The probe opened view/qa?uf_priority=urgent, with window.location set to the same entry, then switched the tab to view/qb, a path with no query string.
On qb the list query still carried ["priority","=","urgent"], and the quick-filter chip read "Priority1". The address bar's search was empty.
The control, view/qb on a fresh mount, queried with no filter.
So a link copied on qb does not reproduce the list on screen. The page applies a filter its URL does not show, which breaks the maintainer's URL contract on objectui#11860 (「视图、筛选、排序、分组都写进 URL」).

Where it comes from (read in source)

packages/app-shell/src/views/ObjectView.tsx: initialUfSelections is captured once per page mount, by a useState initializer that reads window.location.search.
A view-tab switch keeps the page mounted and remounts ListView, whose UserFilters restore the first view's selections from that captured value.

Done when

A switch between two views on one mounted page starts the next view with the quick-filter selections its own URL carries, which is none for a bare view path.
A pin per direction, with a reverse check. A link into a view still restores its uf_FIELD selections; that is objectui#11915's behaviour, and it stays.

Neighbours

objectui#11860 (PR objectui#11991, in review in the domain:spec lane) changes ObjectView.tsx's grouping and sort wiring, not initialUfSelections.

Duplicate check

Semantic issue search on objectstack-ai/objectui, quick filter selections leak view switch initialUfSelections captured once per mount uf_ params stale after view change: 2 hits, both closed. objectui#2219 is about userFilters dropped on an object list view. objectui#2294 is about filters lost across page navigation, the opposite direction. Neither covers this.

Triage: first grade, `bug` · `priority:p3` · `domain:ui` · `area:records` · `pm:queue`. Direction: a view switch reads the new view's own URL, never the first mount's

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-08T16:59Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/app-shell/src/views/ObjectView.tsx (initialUfSelections, captured once per mount) ⇒ domain:ui; rationale: console page state, internal, so Clause-②: no.

Why p3: the same grade as objectui#11860, whose URL contract it breaks: the page applies a filter its URL does not show, so a copied link does not reproduce the list.
Direction: derive the quick-filter selections from the current location on every view change, not from a mount-time capture. Keep the cache precedence objectui#11915 set.
Pins: qa?uf_priority=urgent → qb queries with no filter, and the reverse direction is pinned too. Control: a fresh mount on a filtered URL still applies it.

File surface (on 0bbb67b9a):

packages/app-shell/src/views/ObjectView.tsx: initialUfSelections (about :2878, a useState initializer read once per mount) and where it is handed to ListView (about :3679, :3686). Per triage 6064946799, the quick-filter selections derive from the current location on every view change, not from a mount-time capture, and objectui#11915's cache precedence is kept.
At most one module-private helper beside it.
The tests beside it, and .changeset/11992-*.md.

⛔ Not on it:

userFilterUrlState.ts, which is read but not edited: PR objectui#11991 edits it;
the grouping and sort URL wiring (objectui#11860, PR objectui#11991);
packages/plugin-list/** (ListView / UserFilters), unless the measurement proves the producer is there (stop and report first);
packages/components/src/ui/** and packages/i18n/**.

Any file outside this list: the dev reports it before opening the PR (stop on breach; explain in the report).
Container & model: S, mode:subagent, model: opus (dispatch-gates --tier --repo objectstack-ai/objectui over these paths: no path-derived mandate; default tier)
Clause-②: no
Responsibility: objectui app-shell console list: a view-tab switch keeps the previous view's quick-filter selections while the new view's URL carries none, so a copied link does not reproduce the list | the URL contract of objectui#11860 and the uf_ restore of objectui#11915 | every console user switching views on a filtered list
Thread-read: 6064946799
Serial constraints cleared: overlap declared, not blocking.

Open objectui PRs, read 2026-10-08T17:24Z: PR objectui#11991 (objectui#11860, another lane) also edits ObjectView.tsx, in its grouping and sort wiring. Its hunks sit near this surface's hand-off (about :3653–:3686). Whichever of the two lands second merges main and resolves the hand-off by merge, never by rebase.
In-flight claims read 2026-10-08T17:24Z: none names initialUfSelections.
First-load bytes: the eager headroom is about 0.5 KB. The dev reports the budget bot's reading.

Why Clause-②: no: console page state inside app-shell. No export, prop or packages/i18n key (triage's reading).

In packages/app-shell/src/views/ObjectView.tsx, initialUfSelections is no longer a useState initializer over window.location.search, which read it once per page mount. It is now read from the router's current location (searchParams) once per list identity (listIdentityKey, the same object and view listSeedRef seeds on and renderListView keys the list on), held in a ref per identity so chip writes do not rebuild the list schema. The name, the ListView hand-off and the renderListView dependency list are unchanged, so PR objectui#11991's hunks are untouched; a read-only git merge-tree of this head with its head 848fe53 is clean. H1 holds: at base 0bbb67b the qb tab after qa?uf_priority=urgent queried ["priority","=","urgent"], and the producer is this page, not plugin-list (UserFilters reads initialSelections only in its useState initializer and never reports restored values through onSelectionsChange). The reverse direction (qb, then a link to qa?uf_priority=urgent) was also broken at base, with no filter, and the same change restores it. H2 holds (6 pins green).

Implemented-by: os-dev subagent of session_01MgfduSkFrfM3eorB3UGfAU, branch claude/issue-11992-uf-view-switch, head 6eb2c9f. Report 6066344335.
Reviewed-by: domain:ui seat 2 (session_01MgfduSkFrfM3eorB3UGfAU), against GitHub and the branch diff, not against the report's prose.

Checklist:

PR shape: draft, first line Fixes #11992, Clause-②: no at the start of a line. The assignee is os-bill.
Scope: 3 files inside claim 6065357443: ObjectView.tsx, the new pin and the changeset. userFilterUrlState.ts, plugin-list and the grouping and sort wiring are untouched.
The declared overlap is settled: PR objectui#11991 has since landed. The seat ran git merge-tree of this head against main at review, and it is clean. The ListView hand-off and the renderListView dependency list are unchanged.
Direction met (6064946799):
- initialUfSelections is no longer a once-per-page-mount useState capture over window.location.search.
- It is read from the router's current location once per list identity: the listIdentityKey that listSeedRef seeds on and renderListView keys the list on.
- It is held in a ref per identity, so a chip write does not rebuild the list's schema.
- objectui#11915's cache precedence is kept and pinned.
H1: the producer is this page, not plugin-list. UserFilters reads initialSelections only in its initializer and never reports restored values. The reverse direction (a link back to qa?uf_priority=urgent) was also broken at the base, and the same change restores it.
H2: 6 pins render the real page, plugin-view's ObjectView and plugin-list's ListView under a BrowserRouter. At the base, the qb tab, reverse-link, reverse-Back and cache-precedence pins were red. The fresh-mount control and H3 stay green.
H3: a switch is one history PUSH, the same at the base, under the ablation and with the fix. No URL write was added.
Evidence:
- Every test naming ObjectView, userFilter, uf_ or listUrlState passes, with both repo-wide ratchets: 137 files and 1,835 tests in app-shell, console and scripts, and 191 files and 4,472 tests elsewhere.
- The type-check passes; the first head's TS18048 was fixed and every gate re-run.
- Ablation, putting back the mount-time capture: 4 red and 2 green, as predicted, and the restore was proven.
Changeset: @object-ui/app-shell: patch.
First-load bytes: the budget bot reads 3311.4 KB, against main's 3311.5 KB and the 3312.0 KB ceiling: a PASS.
CI: 6eb2c9f is running, with Bundle Analysis green. The PR lands through the merge queue when every check is green.

Out-of-scope note (carrier: none; read from source only): InterfaceListPage.tsx and ObjectDataPage.tsx keep the same once-per-mount capture over window.location.search. Whether either remounts its list under a page that stays mounted was not measured.
