fix(mobile): model search finds legacy models - #27587
In the mobile Thread settings model picker, Find a model could not find legacy models. Legacy models were removed from each provider group before the search query ran, so typing the exact name of an installed, selectable legacy model (for example Opus 4.8) showed "No matching models" unless Show legacy models was switched on first. The web picker already searches legacy models.
Change
The per-provider filtering that buildThreadSettingsCatalogItems did inline moves into visibleCatalogModels in thread-settings-sheet-state.ts, unchanged, so it can be tested. The fix is one condition there: a non-empty trimmed query skips the legacy collapse, as Show legacy models, Manage hidden models and the Favorites filter already did. An empty or whitespace-only query still collapses legacy models. User-hidden models stay out of search. Provider and Favorites filters still apply.
thread settings sheet state > finds legacy models by search without enabling Show legacy models (apps/mobile/src/features/threads/thread-settings-sheet-state.test.ts) fails on main with expected [] to deeply equal [ 'Claude Opus 4.8' ] and passes here. It also checks that an empty and a whitespace-only query keep the legacy model collapsed.
vp run check:changed: format, lint, knip, typecheck (2 packages), tests and the React compiler check pass.
Real app, Expo dev client against a fresh dev server (T3CODE_DEV_SEED=0), Claude provider's bundled catalog (Claude Opus 4.8 is legacy), Show legacy models and Manage hidden models off, Opus 4.8 neither selected nor favorited. Same scripted sequence on both builds: blank list → type Opus 4.8 → clear → spaces only → clear → Opus → zz-no-model-27573; plus select Opus 4.8, Save, reopen on the fix.
Opus 4.8 → Claude Opus 4.8 with its Legacy badge; clearing or a spaces-only query collapses it again; Opus lists current Opus 5.5 plus legacy Opus 5, 4.8, 4.7, 4.6 and 4.5; selecting Opus 4.8 and saving keeps it after reopening

Evidence
Before 32ecd71726 (merge-base) · After 03ec49bf7f (head). Real Expo dev client (React Native 0.88.0), each revision with its own fresh dev server (T3CODE_DEV_SEED=0), the same synthetic RPC seed, and real authenticated Claude 2.1.303 (13 models, 9 legacy; target Claude Opus 4.8 is legacy, unselected, unfavorited, unhidden). Show legacy models and Manage hidden models are off. The iPhone pairs ran on two simulators side by side, so the status-bar clocks match.
F03: broad search Claude. Before: 4 current rows. After: all 13 rows, with the selected and favorited Opus 5.5 still first and the nine legacy rows inserted. The options frame is scrolled to the bottom so Runtime and Full access are not under the toolbar.
Recordings. Every recording follows the same script: blank, Opus 4.8, clear, Claude Opus 4.8, clear, cLaUdE oPuS 4.8 , clear, claude-opus-4-8, clear, then Claude and scroll to the bottom. The per-step timestamps are in the full evidence.
What else changed: nothing beyond the result list. Inserted legacy rows change the group height, separators and rounded border, and they push Options and Catalog down; the content scrolled behind the translucent iOS header changes with them. The F07 iPhone pairs differ by 198 anti-aliasing pixels at the edge of the unchanged Legacy badge (at most 6/255), and their DiffT is empty. Status bars are identical in every iPhone pair. Videos keep live clocks and natural keyboard timing.
Not covered: on iPhone, the Filter control is not shown while a search is active, and Close clears the query, so the "toggle legacy with the query kept" step exists only on Android (Pixel recording above). Native OS clocks are live, while app Date.now is fixed. The supplementary fixtures S01–S09 (empty, loading and error states, update notices, long labels) are outside this change and were not captured.
Captures: 8/8 required rows, done in two rounds. The first round's iPhone F02/F03 diffs showed the live status-bar clock, so the iPhone pairs were redone on two simulators side by side.
Proof audit pass 2: all rows sufficient except F02/F03 on iPhone (clock) and F07 on iPhone (no toggle recording). After the redo, F02 is sufficient on iPhone in both themes. Two items were accepted as above: on the F03 rows frame the translucent toolbar overlaps the bottom options in both builds, and the separate options frame shows them clearly; F07's ≤6/255 badge-edge residual. The auditor rebuilt F02 on Pixel at head from the uploaded seed and driver: 158 pixels differ, at most 6/255, and none exceed 8/255 (anti-aliasing at the badge edge). The auditor checked against the code that the iPhone search toolbar has no Filter path while a search is active.
Tests: unchanged. finds legacy models by search without enabling Show legacy models is the regression test (see Verification above).
CI: 41/41 checks green on 03ec49b. No merge conflicts.
Unverified surfaces: none. Both the iOS simulator and the Android emulator ran.

visibleCatalogModels (behaviour unchanged) and add a test showing that
searching for a legacy model's exact name returns nothing unless
"Show legacy models" is on. This test reproduces #27573 and fails on main.

Walkthrough
The thread settings model catalog now uses a shared helper to filter and order models. When legacy display is off, a nonempty search query can surface matching legacy models. Tests cover empty, whitespace-only, and matching searches.

Explanation
Issue [#27573] requires name search to surface selectable legacy models without enabling Show legacy models. visibleCatalogModels skips the legacy collapse when query.trim().length > 0, then applies the catalog query and Favorites filter. Empty and whitespace-only queries still collapse legacy models. The caller preserves hidden-model handling, provider grouping, displayed-model handling, and favorite ordering. The regression test covers matching, empty, and whitespace-only queries.

The added test calls visibleCatalogModels directly. It does not detect a regression where buildThreadSettingsCatalogItems stops forwarding session.searchQuery or filters legacy models before the helper receives them. Add a focused test for buildThreadSettingsCatalogItems with a matching query, showLegacy: false, and current plus legacy models. Assert that the returned catalog items include the legacy model.

Add a focused test for buildThreadSettingsCatalogItems using a matching search
query, showLegacy set to false, and both current and legacy models; assert the
returned catalog items include the legacy model. This should exercise the
sheet-to-helper wiring and catch missing session.searchQuery forwarding or
premature legacy filtering.

@coderabbitai On the "Cover the sheet-to-helper wiring" follow-up: not adding it. buildThreadSettingsCatalogItems is a private function in a React Native component file, and the call site is a direct field-for-field forward (query: session.searchQuery). A test for it would only assert that wiring, which this repo's AGENTS.md asks us not to add. The behaviour that changed (legacy collapse vs. query) is covered by the visibleCatalogModels test, which fails on main.
@juliusmarminge Agreed. I withdraw the “Cover the sheet-to-helper wiring” follow-up.
I checked AGENTS.md: Line 105 excludes callback-wiring tests, and Line 107 requires testing at the lowest layer that fails on main, without duplicate wrapper tests. The call passes session.searchQuery directly to visibleCatalogModels. The existing test covers the changed legacy-search behavior.
This also matches the supplied repository Learnings. No additional wiring test is needed.

Learning: In pingdotgg/t3code mobile React Native reviews, distinguish provider-state regression coverage from consumer-level coverage. For PR #13085, apps/mobile/src/features/home/home-list-options.test.ts checks shared filter retention and clearing across repeated compact/sidebar remounts. The author also reports native control and Android query-retention verification. Additional consumer-level tests are a nonblocking improvement unless a concrete defect is identified; do not request tests that merely assert callback wiring or mirror implementation, as AGENTS.md excludes those tests.

Learning: In pingdotgg/t3code, AGENTS.md's Verifying section requires tests of meaningful logic or observable behavior. Do not recommend static-markup assertions, callback-wiring assertions, or tests that mirror the implementation. For React components such as apps/web/src/components/chat/AssistantCitationChip.tsx, mocked popover parts with content-only assertions do not verify opening, closing, source navigation, or highlighting.

Learning: In this repository, `AGENTS.md` prohibits frontend tests that render components to static markup to assert props or attributes, or otherwise mirror rendering implementation details. Prefer tests of meaningful logic or observable behavior. For user-visible frontend changes, an integrated real-client pass is appropriate when requested.

Learning: In the T3 Code repository, `AGENTS.md` requires tests to cover meaningful logic or observable behavior. Do not add React component tests that only assert callback wiring, props, attributes, or mocked `navigate`/handler calls. For user-visible frontend changes, browser validation of the affected flow is appropriate when it covers the behavior.
Verified in the real iOS app on iPhone 18 Pro, portrait, light theme, using identical synthetic catalog/preferences and replay thread history on fresh databases. With another model selected, All providers selected, and legacy/hidden management off, open Thread settings and search Opus 4.8.
The paired runner did not finish successfully; these verdicts come from inspected captures across successful app interactions. Spaces-only entry remains unverified because native automation rejected its text read-back. AI-assisted; verified with the tests and tools listed above.
Not shown:
Spaces-only query: native fill failed its text read-back check; clearing via the visible Clear text button was visually verified.
Android was not exercised; evidence covers iOS.
Live provider authentication and model execution were not exercised; the reproduction used a synthetic selectable catalog.
