PrestaShop core file integrity checks
PrestaShop publishes no hashes of its files. We compute them from the official package of the installed version and compare them with the store, including the admin folder under the name you gave it.
Every store has a different admin folder.
For security, PrestaShop asks you to rename the admin folder. A comparison with the official package, where it is still called admin, cannot find the files or reports them all missing.
The official distribution also contains a second archive with the actual store.
Official package, your store's folder.
Package
We download the distribution of the version from the official catalog and extract the inner archive when there is one.
Admin folder
The agent finds the admin folder and the platform maps the paths.
Comparison
Classes, controllers,
src,vendorand the admin folder must contain official files only.

What about native module files?
Modules updated during a core upgrade are compared with the archive of their version, from the marketplace or the official distribution.
What if I edited a core file?
You see it flagged next to the original. If the change is intended you approve it, and the alert comes back only if the file changes again.
