modules/app_cellular.py: uses the SIM868's built-in AT-command HTTP(S)
client (AT+HTTPINIT/HTTPPARA/HTTPACTION/HTTPREAD) instead of a real
ppp0 interface, since the module's GNSS (polled continuously by
app_gps.py) and its GSM/GPRS radio share the same physical UART
(/dev/serial0) - a pppd/chat dial-up would take over that port
entirely and starve GNSS polling. Staying in AT-command mode lets
cellular HTTP calls interleave safely through the same serial lock.
Only carries small JSON tracking batches, never dashcam video -
cellular is far too slow/limited for that, and the modem's HTTP AT
interface has too small an internal buffer anyway. Dashcam uploads
remain WiFi/Ethernet-only, unchanged.
modules/app_upload.py: tracking-batch upload always tries WiFi/
Ethernet first; only on a connection-level failure (not an HTTP error
status, which means the server was reached) does it retry over
cellular. Exposes last_network_path/cellular_fallback_configured in
/api/upload/status; UI shows which path the last batch used.
Feature-flagged off by default via new YARIS_CELLULAR_ENABLED/
YARIS_CELLULAR_APN/_APN_USER/_APN_PASS keys in db/upload_creds.env
(all blank by default) - has zero effect on the existing WiFi upload
path unless explicitly configured. Regression-tested against the real
deployed server that normal WiFi uploads are unaffected while
cellular stays unconfigured.
*** UNTESTED against real cellular hardware - no SIM card was
*** available. See docstrings in app_cellular.py and PLAN.md for
*** exactly what needs validation once a SIM card is available.

- app_sql.py: add UPLOADED column + migration on tracking table, add
settings and dashcam_uploads tables, add helpers for unsent-row
queries, marking rows uploaded, and dashcam upload dedupe tracking.
- app_upload.py: new background upload client. Periodically batches
unsent tracking rows to POST /api/v1/tracking/batch and uploads new
dashcam files (sha256-verified) to POST /api/v1/dashcam/upload, with
exponential backoff on failure. Exposes get_status() and a
dashcam-upload enable/disable toggle backed by the settings table.
- app.py: start the upload client thread at startup, add
GET /api/upload/status and POST /api/upload/dashcam_toggle routes.
- dash.html/dash.js: add a "Remote server upload" card with upload
status and a toggle switch to pause dashcam video uploads while
trip/GPS log uploads keep running (per user request - useful on a
slow/metered connection).
- db/upload_creds.env: new gitignore-exempted template (mirrors
db/creds.env) for YARIS_SERVER_URL/YARIS_DEVICE_NAME/YARIS_API_KEY.
- requirements.txt: add requests.
Tested against the real deployed unraid server: tracking batch upload
+ dedupe, dashcam upload + dedupe, and toggle-off correctly pausing
dashcam uploads while tracking uploads continue. Also verified the
full Flask app imports/runs cleanly and the new API routes + dash.html
toggle render correctly in a headless browser.

Squashed rewrite of the project revival work (replaces prior history on this
branch to remove personal data that had been accidentally committed - real
LAN IP, GPS coordinates, home WiFi SSID, and phone model). See PLAN.md for
full phase-by-phase details. Summary:
- Phase 2: adapt app_obd.py for a USB OBD-II adapter (was Bluetooth-only),
auto-detect /dev/ttyUSB*, fix several pre-existing crash bugs.
- Phase 3/4: make the web UI work fully offline (vendored Socket.IO/Leaflet/
Chart.js/FontAwesome, offline map tile downloader script, live GPS marker
tracking fix).
- Phase 5: systemd deployment/autostart on the Pi.
- Phase 6: WiFi hotspot mode via NetworkManager (auto-switch between home
WiFi and a local AP for in-car web UI access), mDNS hostname + port 80
redirect so the UI is reachable at a plain hostname with no port number.
- Phase 7: fix app_db.py/app_sql.py bugs, wire up local SQLite trip logging.
- Phase 8: brand-agnostic USB dashcam file retrieval (lsblk transport-based
detection, works with any dashcam brand/folder layout).
- Rewritten readme.md with a proper project overview.
