/meshcomod/apps on the card and /apps internally now take top-level .lua and
.json files, so an app can be side-loaded without pulling the card (Discord).
Everything else there stays read-only: the folder itself, subfolders (<id>.d
data), app save files (.sav, .wgt), hidden names and 8.3 aliases. A change
from the page invalidates the cached app listing, so the drawer and the Store
pick the new app up the next time they open. Host tests cover the policy.

A built-in USB Files app (T-Deck and Heltec V4 for now) lets the page at
files.wadamesh.com browse, upload, download, rename and delete files on the
SD card, internal storage and the map tiles over Web Serial. File level, not
USB mass storage: the device keeps its filesystems mounted, the radio keeps
running, and the firmware enforces what may change. Live data (identity,
contacts, settings, history; /meshcomod on the card) is download-only.
- UsbFilesProtocol.h: framed messages (E7 5A, CRC32), a resyncing parser,
path checks and the access policy; host tests in test/.
- UsbFilesSession: one request at a time (both Arduino USB serial drivers
drop bytes when their RX queue is full), RX queue sized per session, SD
data through a DMA-capable bounce buffer, FatFs listings with sizes, a
beacon so the page never talks first, SD Scan's malware verdict per file.
- The companion link and MyMesh's console step off USB while it runs.
- Website: labelled side buttons, a USB Files button and card; the
files.wadamesh.com page, vhost and deploy script.
