Summary

  • Extracted the inline syllabus breakdown modal from Show.vue into a reusable component SyllabusBreakdownModal.vue.
  • Enabled interactive chapter completion toggling directly within the modal when viewing own profile (isOwnProfile), including optimistic updates.
  • Maintained read-only view for peer profiles.
  • Fixed spacing between curriculum name and group in the profile syllabus progress badge.
  • Updated progress button label to Bengali script (আমার প্রগ্রেস ট্র্যাক করুন).

Summary by CodeRabbit

  • New Features
    • Added a syllabus progress breakdown showing overall and subject-level completion, chapter counts, progress bars, and chapter completion details.
    • On your own profile, you can mark chapters complete or incomplete by clicking or using the keyboard. Progress updates immediately and reverts if the save fails.
    • The breakdown includes an explanation of how progress is calculated, plus options to share or visit the tracker.

📝 Walkthrough

Walkthrough

The profile page now uses a dedicated syllabus progress modal. The modal displays course, subject, and chapter progress, and supports chapter completion updates on the user’s own profile.

Changes

Syllabus progress modal

Layer / File(s) Summary
Progress data and chapter updates
resources/js/components/tracker/SyllabusBreakdownModal.vue
The component defines syllabus data and props. On the owner’s profile, chapter toggles update local progress and post to /tracker/nodes/{chapterId}/toggle. On request error, the component restores the prior chapter state and reloads syllabus progress.
Progress modal content
resources/js/components/tracker/SyllabusBreakdownModal.vue
The modal displays the progress calculation explanation, expandable subject and chapter details, completion controls, and footer actions.
Profile page integration
resources/js/pages/User/Show.vue, resources/js/components/tracker/SyllabusBreakdownModal.vue
The profile page passes the user, syllabus progress, and ownership state to the modal. It connects the modal’s share event to the share modal and formats an optional group name on the syllabus card.

Merge Risk: 🟡 Moderate · up to c6b61

The new syllabus modal lets profile owners mark chapters complete. Two cases can show progress that differs from what was saved: a failed network request, or clicking the same chapter twice quickly. Keyboard users also cannot expand subjects to reach the chapter controls. These issues should be fixed before merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c6b61

Authentication and per-user completion ownership remain intact. The main concern is incomplete recovery of shared progress displays after failed or interrupted updates, rather than expanded access to other users’ data.

Retained concerns

  • Low · reliability · inferred: The new modal mutates the parent’s shared progress projection, but error recovery restores only the chapter flag. Subject and overall aggregates depend on a subsequent reload for repair. If recovery fails or is interrupted, inconsistent progress can remain visible in the profile badge and share input. This introduces incomplete rollback across the component ownership boundary; the previous tracker derives its aggregates from the completion set that its error handler restores.
Security review details

Security Blast Radius

  • inferred — The examined write path is confined to the authenticated account’s completion records. Manipulating the chapter identifier or client ownership flag does not select another user’s records. The new caller additionally affects that account’s in-memory profile and share-progress projection.

Trust Boundaries and Controls

  • observed — The toggle route is inside the authentication and throttle middleware group, and the controller independently rejects requests without a user. The frontend own-profile comparison controls interaction availability, while server-side request-user binding controls whose completion data changes.
  • observed — The unchanged toggle handler does not explicitly restrict nodes to the user’s curriculum or trackable subjects. The existing tracker already calls this endpoint, and the profile projection filters displayed subjects and nodes. This is a pre-existing self-progress scope characteristic, not an established PR-introduced cross-user authorization issue.

Resilience and Maintainability Implications

  • inferred — The database uniqueness constraint prevents duplicate completion rows, but the controller’s read-then-create/delete operation is not an atomic or idempotent state-setting contract. Both the existing tracker and new modal issue unguarded toggles, so this concurrency characteristic predates the PR. The newly introduced recovery concern is the modal’s larger shared rollback state, not newly gained authority.

Hardening Proposals

  • proposed — Give optimistic completion edits a single state owner, derive aggregates from that state, and reconcile or restore the entire projection on terminal failure or interruption. Keeping sharing unavailable while reconciliation is unresolved would contain inconsistent state within the update workflow.

Block another toggle while this chapter’s request is pending.

If the owner activates a chapter twice before the first POST settles, this handler sends two requests to a server endpoint that toggles the record rather than setting a requested value. Inertia visits can be canceled, but cancellation does not establish that the server did not process the first toggle. The displayed state can therefore diverge from the saved state. Track pending chapter IDs and reconcile each chapter before accepting another activation. (inertiajs.com)

Reconcile progress after non-validation request failures.

If the POST fails because of a network interruption or HTTP exception, onError does not run. The optimistic chapter, subject, and overall progress can remain visible even though the update did not complete. Handle Inertia’s onNetworkError and onHttpException paths and restore or reload the affected progress. Inertia documents these callbacks separately from validation onError. (inertiajs.com)

Based on learnings, an optimistic update needs rollback when its backend call fails.

Make subject expansion keyboard-accessible.

If a user navigates by keyboard, this clickable div cannot receive focus or open a subject. The user cannot reach any chapter controls until the subject opens. Use a button for the subject header, and expose its expanded state.
