- _decode_odometer: catch all exceptions and return None instead of raising.
PID 0xA6 (odometer) is not guaranteed on 2013 Toyota Yaris — a garbage
response or unsupported PID previously raised ValueError through python-obd's
decoder, which app_obd._query() caught and treated as a lost connection,
killing the entire OBD session. Now it gracefully returns None.
- connect_obd: reset all sensor globals (rpm, coolant_temp, fuel_level,
throttle_position, mil_on, dtc_codes, odometer, timestamps) on each new
connection so the UI doesn't display stale readings from the previous
ignition cycle while fresh polls are completing.
- yaris-obd.service: add commented OBD_PROTOCOL=6 hint for post-confirmation
pinning (eliminates 3-5s auto-probe delay after first confirmed connection).

- app_upload.py: move json import to top of file instead of inside except handler
- server/app.py: wrap int(request.args.get('limit')) in try/except ValueError
- server/app.py: wrap os.path.commonpath() in try/except ValueError (cross-root paths)
- tests/test_app_settings.py: add missing trips_upload_enabled/video_convert_enabled
to valid_payload() (fields added in Phase 23.5 but test not updated)
All 63 tests pass.

The CSS already handles the arrow direction with transform:rotate(180deg) on
.app-sidebar.collapsed .sidebar-collapse-btn. The JS icon className swap was
fighting with CSS rotation causing a double-flip. Remove JS icon manipulation,
let CSS handle it. Also suppress the button transition on page load.

- New POST /api/local-video/convert route triggers queue_convert(force=True)
- queue_convert() now returns True/False/None and accepts force param
to bypass the auto-convert toggle (manual always works)
- Convert button shown for non-MP4, non-converting files in video list
- Clicking spins the button and refreshes list after 1s to show badge
Co-authored-by: Copilot <[email protected]>
- _convert_bg now runs in real threading.Thread (not gevent greenlet)
so ffmpeg proc.wait() doesn't block gevent event loop

duplicate block that still had scrollIntoView and references to the old
panel elements; new modal-based code is the only path now
Co-authored-by: Copilot <[email protected]>
- app.py: replace send_file with manual Range-aware chunked generator;
returns 206 on partial requests so browsers can seek/buffer properly.
Thumbnail route returns 202 while ffmpeg is generating.
- app_video.py: thumbnail generation moved to background gevent greenlet
(_generate_thumbnail_bg). get_thumbnail_path returns immediately with
RuntimeError('generating') if not cached; ffmpeg only ever runs once
per video (result cached in dash/thumbnails/).
- dash.html: replaced bottom card player with Bootstrap modal (modal-xl,
centered, dark bg) — video pops up in place regardless of scroll position.
- local-videos.js: rewritten to use Bootstrap modal; thumbnail loader
polls with fetch() and retries on 202 every 2s (up to 15x) instead of
setting img.src directly (which can't detect 202).

Recorded Phase 12's deployment step (Pi restart + unraid server
docker compose build/up since server/app.py's CORS removal is baked
into the image at build time - a plain restart wouldn't pick it up)
and its verification (both confirmed on real infrastructure: Pi's
/dash returns HTTP 200 with no relay text, server's /health has no
Access-Control-* headers anymore).
Added a handoff note for whoever picks this up next: Phase 17 (OBD
hardening) was the next phase in progress, but no code was written
yet - only read app_events.py/app_gps.py for context and started
(but didn't finish, due to a tool permission interruption) installing
the python-obd package locally to check its actual API surface
before writing the DTC/protocol/diagnostics code. Reset that todo
back to pending to reflect no actual progress was made. Phases 13
and 14 are equally ready to start (no blocking deps) if a different
starting point makes more sense.

Removes the phone-relay feature entirely per the Phase 11 finding
that it hit a fundamental phone-OS limitation (a browser page can't
route WiFi and cellular traffic simultaneously, no code fix possible)
- see PLAN.md for the full test writeup.
- app.py: dropped /api/dash/pending, /api/dash/file/<path>,
/api/dash/relay/config, /api/dash/relay/heartbeat,
/api/dash/relay/stop, /api/dash/relay/mark_uploaded routes and
their now-unused imports (os, send_file, abort, safe_join).
- modules/app_upload.py: dropped list_pending_dashcam_files(),
relay_heartbeat()/relay_stop()/is_relay_active(),
RELAY_LEASE_SECONDS/_relay_lease_until, and the relay-lease check
inside _upload_dashcam_files()/get_status(). Kept the chunked
upload protocol, dashcam_hash_cache/_hash_dashcam_file() (still
used by the Pi's own background uploader), and DASHCAM_CHUNK_SIZE -
none of that was relay-specific.
- templates/dash.html: removed the 'Relay via phone' card.
- static/js/dash.js: removed all relay JS (relayOneFile,
fetchChunkWithRetry, uploadChunkWithRetry, heartbeat timers,
pending-file list rendering).
- server/app.py: removed the CORS after_request hook, added solely
for the phone's cross-origin browser calls (the Pi's own Python
requests-based client was never subject to CORS).
- readme.md: dropped the phone-relay feature bullet, updated the
project-status blurb to explain the removal + point at the planned
native Android app as the real fix for that use case.
- PLAN.md: marked Phase 12 done with a verification writeup.
Verified: py_compile on all touched Python files, node --check on
dash.js, grepped all touched files for any leftover relay/RELAY
reference (none), and smoke-tested by importing app.py + hitting it
with Flask's test client - app starts cleanly, every relay route is
gone from url_map, and both / and /dash still render HTTP 200 with
zero 'relay' occurrences in /dash's HTML.

Reordered/renumbered the roadmap based on dependency analysis:
- Phase 12 (remove relay) stays first - pure cleanup, no deps.
- New Phase 13: power-loss resilience + hardware watchdog - OS-level,
independent, should land before the Pi lives in the car full-time
(cars cut power abruptly at every key-off, a real SD-corruption risk
nothing in the project currently addresses).
- New Phase 14: UI design-system foundation - pulls forward a small
slice of the old end-of-roadmap redesign (shared layout + reusable
list/table component) so the dashcam/video browsers, trip history,
and settings pages are all built on it once instead of being built
in the old template and then rebuilt during the redesign later.
- Phases 15/16 (dashcam + local video browsers) now explicitly build
on Phase 14's foundation. Folded two more QOL ideas directly into
Phase 16: ffmpeg thumbnails per video, and an optional
upload-confirmed local retention/auto-cleanup policy.
- Phase 17 (OBD hardening) explicitly marked independent/parallel-
frins to other phases - backend-only work, no UI dependency.
- New Phase 18: trip history + map replay (trips table + GPS-gap
boundary detection + list/replay UI reusing the offline Leaflet map).
- New Phase 19: Pi health monitoring card (CPU temp/disk/uptime/RAM).
- New Phase 20: alerts/notifications via a simple outbound webhook
(ntfy.sh/Telegram) for DTC-on, storage full, backlog growing,
overheating, lost GPS fix.
- New Phase 21: consolidated Settings page (upload toggle, cellular
APN, retention policy, alert config) - reduces routine SSH-editing.
- Phase 22: renamed 'Finish web UI redesign' - now scoped as the
remaining cleanup after Phase 14's foundation + all functional
phases land, rather than one big redesign at the very end.
- Phase 23: native Android app, unchanged content, still last/low
priority per explicit user instruction.
Updated the session's todo tracking table to match the new phase
IDs/order and added todo_deps reflecting the same dependency chain.
Co-authored-by: Copilot <[email protected]>
Formatting-only pass, no information changed:
- Added missing checkmarks to Phase 7 and Phase 9 headers (were plain
'DONE' text while every other completed phase uses '✅ DONE').
- Added a status icon to the un-numbered SIM868 cellular fallback
section ('⚠️ built, UNTESTED').
- Added a consistent '🚧 PLANNED' icon to Phases 12-17, which had no
status icon at all.
- Fixed a stale cross-reference in the Phase 6 update ('see Phase 9
update below' -> 'see Phase 11 update below' - the phone-relay
content it points to has always lived under Phase 11).
Co-authored-by: Copilot <[email protected]>
Phase 16: complete web UI redesign - the current template is full of
never-replaced placeholder cruft (stub buttons, empty /dtc page); do
one real design pass once the functional phases land rather than
keep bolting onto the old admin-template style.
Phase 17: native Android companion app - the real fix for the
phone-relay goal that a web page could never deliver (true
simultaneous WiFi-to-Pi + cellular-to-server via
bindProcessToNetwork), plus a trip/location info view. Explicitly
deprioritized to the end of the roadmap per user - not urgent.
Also expanded Phase 15 (OBD hardening) scope to pull richer dashboard
data (coolant temp, fuel level, throttle, DTC/MIL status) alongside
speed/RPM, noting odometer/mileage support is not guaranteed on this
vehicle/year and needs real-car confirmation.
Co-authored-by: Copilot <[email protected]>
Retested the hotspot+cellular phone-relay scenario more rigorously
(netwatch explicitly disabled during tests so it wouldn't yank the Pi
back to home WiFi mid-test - an earlier failed run turned out to be
caused by that, not a phone issue). Confirmed with WiFi fully off
(pure cellular) that requests to the public server still failed while
associated with the Pi's hotspot, and that this is a fundamental
OS-level 'single default network for the whole device' limitation -
not something a web page's JS can work around, only a native app could
(bindProcessToNetwork). Documented the decision to remove the feature.
Added Phase 12 (remove phone-relay), Phase 13 (dashcam USB file
browser: list+delete), Phase 14 (local imported-video browser +
HTML5 player), Phase 15 (OBD code hardening ahead of first real
car test - background reconnect loop, exception handling, protocol
override, better diagnostics).
Co-authored-by: Copilot <[email protected]>
Live-tested the away-from-home hotspot+cellular relay scenario. Found the
netwatch reconnect bug (documented in Phase 6 update) during this test.
Confirmed the relay architecture itself needs no code changes - the
TypeError: Failed to fetch was a phone-OS network-switching behavior
(won't route internet traffic over cellular while connected to a
no-internet WiFi), not a CORS/code issue - ruled out via a plain page
navigation test. Testing this fully requires being genuinely away from
home or manually forcing cellular use on the phone.
Co-authored-by: Copilot <[email protected]>
Real-hardware finding: netwatch repeatedly reported 'home WiFi not found'
4 times over 13min while sitting right next to the router. Root cause:
a plain 'nmcli con up home-wifi' straight out of AP mode relies on NM's
scan cache for wlan0, which is stale/empty coming out of AP mode (the
radio can't scan while acting as an AP). A single con-up attempt didn't
wait for a fresh scan to land before giving up.
Fix: explicitly drop the AP connection first to free the radio, force a
fresh scan with a settle delay, and retry the connect attempt (longer
30s timeout) up to 2 times before conceding and restoring the hotspot.
Bumped the systemd unit's TimeoutStartSec to 180s to give the retry loop
enough headroom (was defaulting to 90s).

Root-caused a "GPS not working" report to the SIM868 module chip being
fully powered off (the HAT's 5V rail can be live while the chip itself
stays off until PWRKEY is triggered) - confirmed by getting zero AT
response at any baud rate while the app's GPS thread had the serial
port open normally.
Discovered this specific HAT revision has the "P4" GPIO power-on mod
wire installed (Waveshare FAQ / GSM_PWRKEY.rar script), letting PWRKEY
be triggered via physical pin 7 (BCM GPIO4) instead of a manual button
press. Verified live: pulsing it low for 4s then high brought the
module from zero AT response to responding immediately.
modules/app_gps.py: added _module_responds()/_pulse_pwrkey()/
_ensure_module_powered(), wired into _poll_loop() before the existing
GNSS power-on check. Checks AT first and only pulses PWRKEY if the
module isn't already responding, since PWRKEY is a toggle (pulsing an
already-on module would turn it back off).
Also fixed a related logging gap found while debugging: print()
diagnostics from app_gps.py were invisible in yaris-obd.log for
months because Python fully-buffers stdout when it isn't a TTY.
deploy/yaris-obd.service now sets PYTHONUNBUFFERED=1.
requirements.txt: added RPi.GPIO.
PLAN.md: documented both findings and the Pi deploy gotchas (systemd
unit file changes need a manual copy + daemon-reload; requirements.txt
changes need a manual venv pip install - neither is picked up by a
plain git pull + restart).
