Skip server file listing for guest accounts

[Frooodle]

Description of Changes

• useFileManager no longer requests /api/v1/storage/files or /api/v1/storage/share-links/accessed for guest (anonymous) accounts.
• Adds useFileManager.test.ts, covering the guest path and the signed-in path.

Why: guests have no server storage. FileStorageService.requireAuthenticatedUser answers them with 401, because a guest's principal is the raw JWT rather than a User. Nearly every tool mounts FileStatusIndicator, which calls this hook, so every tool opened by a guest sent these requests. Each 401 made the SaaS apiClient refresh the Supabase token and retry. The user saw nothing, but it was wasted traffic and a token rotation on every tool open. Other storage code (fileSyncService, FileSidebar, FolderContext) already gates on isAnonymous in the same way.

📝 Walkthrough

Walkthrough

useFileManager now checks authentication before fetching server storage files. Anonymous users do not trigger server-file requests. Tests cover anonymous and non-anonymous request behavior.

Changes

File Loading

Layer / File(s)	Summary
Authentication-gated file loading frontend/editor/src/core/hooks/useFileManager.ts, frontend/editor/src/core/hooks/useFileManager.test.ts	useFileManager reads isAnonymous and only fetches server storage files when storage is enabled and the user is not anonymous. Tests verify no API requests for anonymous users and requests for both storage files and accessed share links for non-anonymous users.

Priority: ➖ Normal

Change: Bug fix

Suggested reviewers: jbrunton96

Merge Risk: 🔵 Low · up to f3f35

The change may still send server-file requests for guests using the core authentication implementation. Confirm the authentication binding in supported guest builds before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to f3f35

Guest accounts should stop making unnecessary storage-list requests, while signed-in accounts retain them. A possible timing issue remains: if a signed-in load finishes after the account becomes a guest, earlier file names could reappear in the file picker. This was not shown to bypass server access controls.

Retained concerns

• Medium · security · inferred: A pending signed-in file load can complete after a guest load and restore prior-account file metadata to a still-mounted file picker. Skipping the guest requests changes the completion ordering without invalidating the older result.

Security review details

Security Blast Radius

• inferred — The changed request policy affects consumers of the shared hook, including the tool file-status indicator and saved-file picker; it reduces guest listing calls rather than adding a server entrypoint.

Security Findings and Attack Paths

• inferred — If the picker remains mounted through an account-to-guest transition, a late account response can replace the newer guest result with prior-account file metadata. The available evidence does not establish a server-side authorization bypass.

Trust Boundaries and Controls

• observed — The guest check controls whether this client hook issues listing requests. Tests confirm no API call for a mocked guest and both existing listing calls for a mocked non-guest; they do not exercise the production identity transition.

Resilience and Maintainability Implications

• observed — The inspected consumers accept completed loads without a request-generation or current-identity check, despite starting another load when the hook callback changes.

Hardening Proposals

• proposed — Bind recent-file results to the initiating identity or request generation, and discard results that complete after that identity changes.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Connect the guest check to authentication state.

The supplied useAuth implementation in frontend/editor/src/core/auth/UseSession.tsx:43-54 always returns isAnonymous: false. When storage is enabled, shouldFetchServerFiles therefore remains true for guests. Both requests still run, so this change does not prevent the reported 401 responses. Make useAuth return the actual guest state. The test mock does not verify that integration.
