1) Customers > Homework Detail — Media Upload & Processing Flow
- Fixed video upload flow so uploads go directly to Cloudflare R2 only.
- Removed synchronous processing and infinite “processing” spinner.
- After upload:
- UI shows a stable placeholder “Upload thành công”.
- Status is persisted in DB (uploaded / scheduled / processing / ready / failed).
- Video processing is now dispatched as a delayed queue job (1 minute) instead of 1 hour.
- Customers no longer need to wait on the page for processing to finish.
2) Customers > Homework Detail — Skill Progress Logic
- Removed the manual “Đánh dấu hoàn thành” button.
- Skill completion is now fully derived:
- A skill is marked as done automatically when all links inside the skill are completed.
- Link-level checkboxes remain the single source of truth.
- Backend recalculates skill status on each link toggle.
- Status stays consistent across Customer / Teacher / Admin views.
3) Customers > Homework Detail — Admin Comments Visibility
- Admin comments added at student + homework + skill level.
- Customers now see the Admin’s comment directly inside the related skill section.
- Comment is displayed only when it exists (no empty placeholders).
- Data is loaded in the main homework detail payload (no per-skill requests).
4) Admin > Academic > Homework Detail — Proof & Review Improvements
- Skill status cells now show a proof indicator icon even if the parent did not mark the skill as done.
- Clicking the icon always opens the proof modal.
- Added Admin comment input inside the proof modal:
- Comment is scoped to student + homework + skill.
- Persisted in DB (single comment per skill).
- Re-opening the modal shows the saved comment.
5) Admin Proof Video Playback — Processing Fallback
- When Admin views a proof video:
- If optimized video exists → play optimized.
- If video is still processing → fallback to original video for immediate playback.
- Removed blocking “processing” state for Admin review.
- Video aspect ratio issues were fixed so previews no longer stretch.
6) Admin > Insights > Media — UX Refinements
- Clarified Media scope to include all photos and videos:
- student photos
- homework completion proof
- homework-related media
- Removed date range filter.
- “Related Entity” column is now clickable:
- Navigates directly to Admin > Academic > Homework > Detail when applicable.
- Fixed stretched video preview by enforcing correct aspect ratio in modal.
7) Android Upload Bug Fix (Customers)
- Fixed file picker issue on Android devices (e.g. Samsung S25) where only images were selectable.
- Updated file input configuration so the picker shows both images and videos.
- Backend validation aligned to accept both media types.
- No regressions on iOS or desktop.
8) Media Cleanup Tooling
- Designed a new Artisan command to clean up storage:
- Safely removes original images/videos after processing succeeds.
- Keeps optimized variants only.
- Supports dry-run, chunking, and safety guards.
- Intended to reduce Cloudflare R2 storage usage.
