BITESIZE READING LIBRARY V4.8.1 — SMART STUDIO INSTALLER
====================================================
Experimental update built from the supplied Reading Library V4.8.0.

THE SIMPLER TEACHER WORKFLOW
1. Open START_READING_LIBRARY.html in Chrome or Edge.
2. Choose Add Resource and drag in the original registered Reading Studio ZIP.
3. The Studio appears in My Library. On first use, choose “Choose your Library folder once” and select the folder containing START_READING_LIBRARY.html.
4. The Library checks the folder and installs all Studio files automatically. Click Open Teacher Mode.
5. For FUTURE Studio ZIPs, simply drag the ZIP into Add Resource. When folder access remains granted, the Library automatically installs the files into System/studios/PRODUCT_ID as part of import. No second unzip, folder selection or setup page is needed.

UPDATING A STUDIO
- Re-import the newly registered ZIP with the same permanent Product ID. If folder access is still granted, the revised files are installed automatically.
- If permissions have changed, choose Finish Studio setup / Reinstall to select the Library folder again.
- The original registered ZIP remains stored in the browser's resource database, as before.

UPGRADING AN EXISTING READING LIBRARY
- Back up your existing Reading Library Files folder before installing the V4.8.1 patch.
- IMPORTANT: Keep the same folder path and same browser profile. Your existing resource ZIPs, classes and assessment records are stored in browser IndexedDB/localStorage, NOT inside the Reading Library software ZIP.
- For an in-place upgrade, extract the V4.8.1 UPGRADE ONLY archive over your existing Reading Library Files folder, maintaining the folder structure. Do not delete your current Reading Library folder.
- Alternatively, use the complete V4.8.1 package for a fresh installation.

WHAT DOES NOT CHANGE
- You still need a legitimately acquired, registered Studio ZIP. The software ZIP does not contain The Headless Horseman or other purchased Studios.
- Chrome/Edge and OS security may require the user to authorise the Library folder once (or again if permission expires). A website cannot silently write files without permission.
- Browsers without the required folder-write API still have the manual extract option in Advanced options.
- Only Catalogue Manager-verified Product ID relationships and standards are treated as verified. Installing a Studio never changes or verifies Core reading product links.
- Teacher-only materials remain on the teacher's machine. Do not distribute the entire teacher package to pupils.
- All importing/installing is local; the Studio directory handle is kept in the existing browser IndexedDB, not sent online.

TECHNICAL CHECKS
- Main app JS syntax: checked with Node.js.
- Headless Horseman 36 MB real ZIP: extracted 102 files in a simulated File System Access API directory; System/index.html confirmed present.
- Missing launch page and non-Library target folder: rejected in installer tests.
- Existing app file integrity and ZIP contents: checked.
- Actual file:// browser launch, native OS folder chooser and browser permission persistence were not verified in this environment, so test on a normal Windows/Mac Chrome or Edge installation before public distribution.
