fix: open log tabs instantly with safe prefetching - #755
Log tabs keep showing the previous feed until the request finishes. Use Inertia instant visits to open the selected tab immediately with the existing feed skeletons, and restore hover prefetching.
Keep log GET requests read-only and save the last displayed feed separately, so prefetching and cached visits do not overwrite the preference.
click a log tab
- wait for the response, then switch tabs+ switch tabs and show feed skeletons immediately+ display the response and remember the loaded feed
Evidence
Recorded locally with the same demo data, click timings, and a 700 ms feed-response delay. The first click has no prefetched response; later clicks follow a hover.

New Features
Your preferred log is saved to your account and restored as you navigate.
Log tabs provide loading feedback and can begin loading before you select them.
Failed log loads offer a retry option.
Bug Fixes
Following a log works even when commit data is unavailable on the current page.
Returning to a log page restores its content when data is missing from browser history.

fix: open log tabs instantly with safe prefetching
Oct 20, 2026
This message is generated by gpt-6.1-sol on behalf of xHeaven. It may contain errors—verify important details.
Two reproduced navigation bugs need fixing:
Hover a log tab, click before its prefetch completes, then let it succeed. The app blanks with Cannot read properties of undefined (reading 'toString'). show.tsx:110–113 copies auth.log into the instant page without preserving its once-prop registry; the prefetched response then cannot restore the omitted value. This affects guests and signed-in users.
Fail that pending prefetch instead. page-tabs.tsx:69–75 clears pending state but never invokes the failed-log handler, leaving skeletons indefinitely without “Try again”.
Please cover both sequences with regression tests. Also delay skeleton visibility by about 300 ms, as required by the UI guidelines.
The pull request moves log preference updates to a dedicated authenticated endpoint. It adds client-side preference tracking, and it updates log navigation to use pending state, prefetch control, and deferred feed loading.
Changes: Remembered-log update and shared log state
Layer / File(s)
Summary
Endpoint and shared log state app/Http/Requests/UpdateUserLogRequest.php, routes/web.php, app/Http/Controllers/UserLogController.php, app/Http/Controllers/LogController.php, app/Http/Middleware/HandleInertiaRequests.php, tests/Feature/Controllers/*LogControllerTest.php, tests/Feature/LiveUpdatesTest.php
The app adds an authenticated PUT settings/log endpoint. Log-page requests no longer update the stored log. Shared Inertia state now serves a cached auth.log value, and the feature tests cover the update flow, validation, unchanged values, and page refresh behavior.
The app layout starts the remember-log hook. The hook tracks the active log, saves changes through the new endpoint, and reconciles local and remote log values. The helper serializes queued saves and handles conflicts and failures.
Log tabs now pass per-tab visit options, pending state, and error handling. The log page renders deferred commit data with loading and retry states. Follow requests skip the through header when commits are missing. The updated guidance text matches the new log-navigation behavior.

Log tabs switch immediately and show skeletons while the feed loads. The remembered log is now saved through a separate authenticated endpoint. The previously reported once-prop error was traced to source and no longer applies at head, so no merge-blocking issue remains.
Security architecture risk: Low · up to 02231
The new write is limited to the signed-in user's feed preference, with validated values and existing private-update controls. No cross-user access expansion was identified. The main remaining uncertainty is synchronization across cached navigation, concurrent pages, and live updates rather than increased privileges.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
observed — The new mutation's direct authority is one authenticated user's remembered feed, selected from Following, Latest, and Trending. It accepts no target-user identifier and does not introduce a broader administrative operation.
Trust Boundaries and Controls
observed — The endpoint is inside the authenticated web-route group. Application configuration retains the standard web middleware stack, with no settings/log-specific CSRF exemption observed; CSRF enforcement is inherited rather than implemented in the controller.
observed — The existing broadcast authorization request permits only private-users.{authenticated user ID}. Its authorization response is marked private and no-store, preserving the recipient boundary used by preference notifications.
Resilience and Maintainability Implications
observed — Client preference state is reset when user identity changes. Save and reconciliation callbacks check the captured identity before issuing further requests. These guards do not cancel a request already sent before the transition.
