- PLAN.md: mark Phase 8 (dashcam retrieval) verified on real hardware, add
Phase 10 documenting the OOM/multipart and Cloudflare body-size fixes plus
the chunked/resumable upload redesign, both verified end-to-end against
real dashcam footage. Update architecture decision #3 (Mongo -> Postgres
supersession), add unraid/Pi deploy notes and memory-budget gotcha.
- readme.md: refresh feature list (remote upload, chunked dashcam uploads,
toggle) and project status (all 10 phases done, only cellular fallback
untested).
- server/README.md: document the new chunked upload endpoints and the
Cloudflare body-size-limit rationale behind them.
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.

Reflects the completed deployment: server running on unraid, exposed
at https://yaris.ceaf.dev via Cloudflare Tunnel, Pi-side upload client
live and backlog-drain tuned.

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.
