## Notebook evidence
- [[Scanned_20260730-1719#PDF page 17 — Windows packages, connected devices, and alternate operating systems|PDF page 17: Windows packages, connected devices, and alternate operating systems]] — The page begins in Windows package archaeology and then escapes into alternate operating systems. The common question is how a device’s application model can be replaced or extended across Windows, Chromium, Android, and mobile Linux.
- [[Scanned_20260730-1719#PDF page 25 — antiX, runlevels, terminals, and an alternate-OS shortlist|PDF page 25: antiX, runlevels, terminals, and an alternate-OS shortlist]] — The author is testing how low-resource or alternate systems reach a usable graphical environment and how files enter that environment. The shortlist ranges from desktop Linux to Chromium OS and mobile OS, reinforcing that the target is a transferable computing experience rather than one distribution.

## Evidentiary status and open leads
Resolve the APPX publisher suffix and whether “IHDR” is a filename, PNG chunk type, or acronym copied from inspection output.
### Disambiguation: FydeOS and “Fyade”
Do not normalize “Fyade” in [[Scanned_20260730-1650#PDF page 4 — Librem 5, Inseego hotspot, SIM provenance, and “Fyade” concern|Scanned_20260730-1650, PDF page 4]] to FydeOS. The corrected reading is “Fyade installed” in a passage about T-Mobile SIMs and the girls’ phones. The vault owner recalls another note suggesting “maybe Fing,” but that wording has not yet been located in the integrated Markdown corpus. No package identifier, vendor, screenshot, or other evidence currently connects “Fyade” to FydeOS. See [[Fyade Software|Fyade Software]] for the unresolved reference.
