fix: sync model favorites and visibility across clients

[jakeleventhal]

Favorites and hidden models were saved separately on each device, so desktop changes did not reach mobile. Save model preferences on the selected environment and use live server updates across web/desktop and mobile, with migration of existing preferences and explicit clears preserved. Model edits use explicit desired states and update the server's latest preferences without replacing unrelated changes. Favorite controls track local intent through pending writes and delayed config updates, so rapid clicks keep toggling correctly.

Scope and approval: This addresses one existing model-preference problem: clients connected to the same environment had separate favorites and visibility lists. The contract, persistence, migration, and client changes make those preferences shared. Mobile management provides the hide/restore controls needed to exercise that existing preference capability in both directions. Maintainer approval of the environment-scoped persistence and mobile management scope remains pending.

Mobile's model picker also includes Manage hidden models, with hide and restore controls.

The orchestrator_capabilities MCP tool also leaves hidden models out of the catalog agents choose delegate models from. Custom models stay listed, matching the client pickers.

The side-by-side screen recordings show the web UI shared with desktop beside the native iOS simulator, connected to the same isolated server. They demonstrate favorite changes, hiding, and restoring models in both directions without reloading the receiving client.

Favorites: add and remove in both directions

Hidden models: hide and restore in both directions

Recordings run at normal speed. The web view is cropped to the model controls; captions identify the initiating client.

Validation: focused contract, shared, server, web, and mobile tests, including nine favorite-race regressions (100 focused tests in the latest follow-up); contracts, shared, server, web, and mobile typechecks; targeted lint. iOS simulator and web integration verified. Android was not run because this host has no Android SDK.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces environment-shared model preference persistence, migration, mobile hidden-model management, and MCP catalog filtering across web, mobile, server, and shared contracts. Those changes modify existing model-selection behavior and introduce a meaningful agent model-availability gate, requiring human review.

📝 Walkthrough

Walkthrough

Model favorites, visibility, and ordering are stored in environment server settings, with migration from legacy preferences. Web and mobile controls read and update environment-scoped preferences. Mobile catalogs support hidden-model management.

Changes

Model preferences

Layer / File(s)	Summary
Preference contracts and server updates packages/contracts/src/settings.ts, packages/contracts/src/settings.test.ts, packages/shared/src/serverSettings.ts, packages/shared/src/serverSettings.test.ts, apps/server/src/serverSettings.test.ts	Settings contracts add nullable server preference fields and migration and incremental update patches. Server helpers resolve legacy values and apply preference changes. Tests cover patch behavior, migration, persistence, concurrency, and broadcasts.
Web preference migration and updates apps/web/src/hooks/useSettings.ts, apps/web/src/hooks/useSettings.test.ts, apps/web/src/hooks/useSettings.favorites.test.tsx, apps/web/src/components/settings/useScopedSettings.ts, apps/web/src/components/settings/scopedSettings.ts, apps/web/src/components/settings/scopedSettings.test.ts, apps/web/src/components/settings/useScopedModelAvailability.ts	Web hooks resolve and migrate preferences for an environment and prepare environment-scoped updates. Scoped settings invoke migration and route preference patches to the selected environment.
Web environment preference controls apps/web/src/components/chat/*, apps/web/src/components/settings/*	Model pickers receive an environment ID and read environment preferences. Provider settings submit visibility, favorite, and ordering changes through environment settings. Settings availability checks use merged environment settings.
Mobile model catalog and controls apps/mobile/src/components/AppSymbol.tsx, apps/mobile/src/features/threads/*, apps/mobile/src/lib/modelOptions.*, apps/mobile/src/persistence/mobile-preferences.ts	Mobile catalogs apply provider-specific hidden-model and ordering preferences. Thread settings add hidden-model management and update server preferences. Model rows show hidden state and expose hide controls.

Merge Risk | ⚪ Minimal · up to df226

Merge Risk: ⚪ Minimal · up to df226

Model favorites and visibility now sync through environment settings. The review found no remaining concrete defects.

Security Architecture Review

Security architecture risk: 🔵 Low · up to df226

The change makes preference edits affect every client connected to the same environment. Inspected write paths retain environment permissions, preserve explicit clears, and persist updates before publishing them. No security regression was established, but mixed-version and downgrade behavior remain incompletely verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The newly shared outcome is environment-wide: an authorized settings writer can change preference displays for other connected clients. The inspected path routes to the selected environment and does not demonstrate authority over another environment or model execution.

Trust Boundaries and Controls

• observed — The unchanged authorization classifier places new preference fields under AuthSettingsWriteScope. Mixed patches that also change provider-management fields require both relevant scopes, and the connection authorization layer rejects missing scopes.
• observed — Existing server redaction remains on initial settings responses and settings-update broadcasts. It removes credential-bearing provider environment values and management/access tokens before delivery to clients.

Resilience and Maintainability Implications

• observed — Server-owned null-only migration prevents another client from resurrecting cleared preferences, while serialized latest-snapshot application prevents unrelated client edits from being replaced by stale preference snapshots.

🧹 Nitpick comments (1)

apps/mobile/src/features/threads/ThreadSettingsSheet.tsx (1)

435-437: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Use the migration favorites from the current snapshot.

Line 436 sends modelFavorites, which comes from the render-time closure. Lines 403-405 compute favorites from currentSettings, the registry snapshot taken at call time. Both values merge the same legacy favorites, so they normally match. One case differs: settings become non-null between the render and the tap, but the guard reads currentSettings.favorites === null. Sending favorites keeps the migration payload consistent with that guard, and modelFavorites can then leave the dependency list.

Proposed fix

-                ? { migrateModelPreferences: { favorites: modelFavorites } }
+                ? { migrateModelPreferences: { favorites } }

Validation: hidden models leave orchestrator_capabilities

Ran against bde5fdfbc4 on an isolated dev server (vp run dev:server, worktree-local state, real provider catalogs).

1. Signed in as an MCP client through the real OAuth flow (register → pairing-code approval → token exchange).
2. Changed visibility over the WebSocket RPC with the same server.updateSettings / setModelsHidden patch the clients send.
3. Called orchestrator_capabilities over /mcp after each change, with no restart in between.

Step	codex lists gpt-6-luna	claudeAgent lists claude-haiku-4-5
Baseline	yes	yes
Hide both	no	no
Restore both	yes	yes

All other models stayed listed in order. The saved preferences after hiding were {"codex":{"hiddenModels":["gpt-6-luna"]},"claudeAgent":{"hiddenModels":["claude-haiku-4-5"]}}, and after restoring both lists were empty.

Custom models stay listed even when their slug is in hiddenModels, matching the client pickers. A unit test covers this (leaves models the user hid out of the capability catalog). delegate_task still accepts a hidden model if an agent names it explicitly. This change only affects the catalog.

Validated with Claude Opus 5.5 via Claude Code.

Note

This comment is posted by Julius' dot

Does the recent maintainer follow-up also approve moving device-local preferences to shared environment state, adding mobile hide/restore controls, and filtering the MCP model catalog? The description still says scope approval is pending. The recordings demonstrate synchronization, but this product-direction decision needs an explicit maintainer answer before review handoff.
