   Update, in text this time since the original report is a PDF.

   The symptom changed for this app:

   • 2026-09-25: every screenshot URL answered File not found (14 bytes).
   • 2026-10-02: the same URLs answer HTTP 200 with an empty body (0 bytes). Our last release (1.1.3) was published on 2026-09-30.

   Source, still fine:
   https://raw.githubusercontent.com/a-missaoui/EmpreinteLive/v1.1.2/screenshots/files-present.png → 200, image/png, 183553 bytes

   Through the mirror:

   This now matches #26, and the extended_occweb report there. A sample that may help: of the 25 apps in apps.json with a release after #31 was merged, I checked 45 screenshot URLs: 23 are served and 22 return an empty body, across raw.githubusercontent.com, github.com, gitlab.com and cdn.jsdelivr.net. So the key now exists but holds an empty file.

   I can't tell whether #31 is deployed yet. Feel free to close this as a duplicate of #26 if you prefer to track it there.
