TK Offline Readiness
Offline troubleshooting trees and worksheets are available when the app shell is cached. OEM PDFs require separate caching; iOS may evict caches under storage pressure. A working online session does not guarantee offline readiness.
How to test
- While connected, open the Field Diagnostic Suite and select Cache all bundled manuals. Wait until all five report cached.
- Run the check above.
- Turn on Airplane Mode, then reopen this app from the Home Screen.
- Open an alarm tree, an OEM PDF, and your saved repair notes.
- Keep the deployment ZIP and a local-data backup in the iPhone Files app.
The PDF text-indexing engine is currently hosted externally. Importing/search-indexing new PDFs may not work offline until that library is bundled locally. Cloudflare Access authentication may also require an online session or reauthentication after expiry.
