-### BUG-19 — Dashboard OBD values slow to appear while the car is running
- **Status**: `OPEN` 2026-08-13
- **Phase**: 29
- **Symptom**: on the Pi dashboard, the speed/RPM/coolant/fuel/throttle cards stay on
-  "—" for a long time after the page loads (or after ignition) before populating, even
-  though the car is running and OBD is connected.
- **Cause**: the value cards were populated **only** by socket.io push events from the
-  OBD polling threads — the dashboard never pulled a current snapshot on load, so a
-  freshly loaded page had to wait for the next poll tick (plus any reconnect/probe
-  latency). `/api/obd/status` only returned the connection state, not the actual
-  values, so there was no REST fallback either.
- **Fix**: emit a full current-value snapshot on socket connect, and extend
-  `/api/obd/status` to return live speed/RPM/coolant/fuel/throttle/MIL so the dashboard
-  fills the cards immediately on load (and every 15 s) via REST. Needs in-car
-  verification.

-### BUG-23 — Pi and server trip counts diverge (server drops short trips the Pi keeps)
- **Status**: `CLOSED` 2026-08-15
- **Commit**: `78aea2d`
- **Fix**: the Pi's `build_trip_summaries()` now applies the same minimum-trip filter as the
-  server (`duration < 30s OR distance < 0.05km` → reject), so GPS lock-in drift while the
-  car is stationary no longer spawns false trips. It also sorts normalized rows by
-  `datetime` (the server orders by `recorded_at ASC`), so clock-rollback rows can't make a
-  trip span a backwards time jump. `TRIP_BUILD_VERSION` bumped 3 → 4 to force a Pi rebuild.
- **Verification**: unit tests updated and pass (12/12), including a new regression test for
-  short GPS-drift rejection. On the Pi, trips dropped **57 → 49** after rebuild
-  (`trip_build_state` = (8562, 4)). The remaining gap vs the portal's 10 is the 41
-  intentionally-deleted trips (server-side `deleted_trip_markers`) plus ~2 trips from the
-  server holding 279 more raw points than the Pi — both documented in the original analysis,
-  not regressions.
-
-### BUG-24 — OBD adapter stalls mid-drive; speed flatlines until the next ignition cycle
- **Status**: `CLOSED` 2026-08-15
- **Commit**: `b0ad6fd`
- **Symptom**: on trip #8 (2026-08-13, 09:59–14:50), OBD speed went **102 → None** at
-  **14:14:31** and never recovered for the rest of the trip (~36 min). The log showed only
-  `No speed data received. #['14:16:35', 102.0]` — the ELM327 returned null speed responses
-  while still reporting `CAR_CONNECTED`, so the 10s reconnect loop never fired. Same stall
-  class as BUG-21 (which happened to recover on its own after ~20 min).
- **Fix**: `obd_speed()` now counts consecutive null-speed polls; after 10 nulls (~20s) it
-  force-closes the connection via `_mark_connection_lost()`, so `_reconnect_loop` re-runs
-  `connect_obd()` and the adapter is re-handshaken instead of silently flatlining until the
-  car is restarted.
- **Verification**: deployed to the Pi; the forced-reconnect path will be exercised on the
-  next real stall (in-car verification pending).
-
-### BUG-25 — Security hardening for the internet-exposed remote portal
- **Status**: `CLOSED` 2026-08-15
- **Commit**: `24250e0`
- **Findings** (security review of `https://yaris.ceaf.dev`):
-  1. **Path traversal → arbitrary file write** in `POST /api/v1/dashcam/upload/chunk` — the
-     `sha256` form field was concatenated into the chunk staging path with no validation, so a
-     digest like `../../../../tmp/x` escaped `DASHCAM_STORAGE_DIR` and let a device-authenticated
-     caller write files anywhere inside the container (as root — no `USER` in the Dockerfile).
-  2. **No login rate limiting** — `/login` was brute-forceable.
-  3. **Session cookies lacked Secure/SameSite flags.**
- **Fix**:
-  1. `sha256` is now validated as a 64-char hex digest (`_is_valid_sha256`) on the single-shot
-     upload, chunk-status, and chunk-upload endpoints before it is used in any filesystem path.
-  2. In-memory failed-attempt limiter on `/login` — 8 failures / 15 min per client IP (keyed from
-     `CF-Connecting-IP`, falling back to `X-Forwarded-For` then `remote_addr`) plus per-username;
-     returns 429 when tripped. The app runs as a single gunicorn worker, so process-local state
-     is sufficient (documented in a code comment for a future multi-worker deployment).
-  3. `SESSION_COOKIE_HTTPONLY` + `SESSION_COOKIE_SAMESITE="Lax"` + `SESSION_COOKIE_SECURE`
-     enabled (Secure can be disabled with `COOKIE_SECURE=0` for plain-HTTP LAN login; env var
-     documented in `server/.env.example`).
- **Verification**: `python3 -m py_compile server/app.py` clean; deployed to unraid, `/health` OK.
- **Remaining exposure (not code)**: the Pi's own web app (192.168.50.220:5000) is unauthenticated
-  and binds all interfaces. It is not tunnel-exposed, but a compromised server container could
-  reach it if the 192.168.10.x (Unraid) and 192.168.50.x (home) subnets route to each other —
-  isolate those VLANs.
-
-### BUG-22 — Trip max speed ignores GPS-only stretch (shows OBD max only)
- **Status**: `CLOSED` 2026-08-14
- **Commit**: `90cfd7b`
- **Fix**: `max_speed_kmh` was computed from OBD speeds only, so the top speed reached during
-  the 20-min OBD dropout wasn't reflected. Both trip builders now union OBD speeds with
-  GPS-derived speeds computed over a trailing ~30s window (`GPS_SPEED_WINDOW=6`) to average out
-  GPS position jitter — raw 5s segments swing wildly (e.g. 58→141→58 km/h, peaks ~162), so an
-  unsmoothed union overshoots the real top speed. Also bumped `TRIP_BUILD_VERSION` to force a
-  Pi-side trip rebuild.
- **Verification**: trip #9 max went 111 (OBD-only) → 162 (raw union) → **119** (smoothed), and
-  trip #8 → **127.8**, identical on the server and the Pi. The 135.6 the scrubber showed was a
-  single noisy 5s GPS sample, not the sustained top speed.
-
-### BUG-21 — OBD speed drops out mid-drive, replay shows 0 km/h (GPS-only)
- **Status**: `CLOSED` 2026-08-14
- **Commit**: `7c8f27b`
- **Fix**: the Pi's OBD adapter (ELM327) stopped returning speed for ~20 min on 2026-08-13
-  (last OBD reading 22:23:50 UTC, back at 22:43:41 UTC), so the portal replay flatlined at
-  0 km/h for that stretch. The server's `get_trip_route()` now mirrors the Pi's `route_points`
-  GPS-speed fallback — when OBD speed is missing it derives speed from the previous point's
-  movement (haversine / elapsed time, ≥8 m, ≤220 km/h). The Pi's own replay already did this;
-  only the portal was missing it.
- **Verification**: trip #9 points at 22:23:55 previously returned speed 0.0 — now return
-  GPS-derived speeds (e.g. 61.9 km/h at 22:23:55, labelled `gps`). API rebuilt + healthy.
- **Follow-up**: see BUG-24 — the adapter stalls and returns null speed without dropping
-  the "connected" status; fixed with a reconnect-on-stale-speed guard.
-
-### BUG-20 — Server trip IDs inflate far beyond the real trip count
- **Status**: `CLOSED` 2026-08-14
- **Commit**: `9af71e2`
- **Fix**: `trips.id BIGSERIAL` burned a sequence value on every upsert in
-  `compute_trips_for_device()` (which runs after every upload batch), so IDs climbed far past
-  the real trip count. Now the sequence is clamped to `MAX(id)` after each recompute
-  (`server/modules/db.py`), and a one-time migration (`server/sql/migrate_phase29_trip_ids.sql`)
-  renumbered existing trips compactly and reset the sequence.
- **Verification**: before — `COUNT=10`, `MAX(id)=27091`; after — `MIN(id)=1`, `MAX(id)=10`,
-  sequence `last_value=10` (next insert gets 11). API container rebuilt and healthy.
-
-### BUG-18 — Pi needs offline timekeeping (no RTC)
- **Status**: `CLOSED` 2026-08-14
- **Commit**: `bf4f3d3`
- **Fix**: DS3231 RTC module installed on the free I²C bus (SDA pin 3, SCL pin 5, 3.3V pin 1,
-  GND pin 6) with a CR2032 (charge diode removed). Pi config: `dtparam=i2c_arm=on` +
-  `dtoverlay=i2c-rtc,ds3231` in `/boot/firmware/config.txt`, `i2c-tools` installed,
-  `fake-hwclock` disabled, `i2c-dev` persisted via `modules-load.d`. CR1220 also installed in
-  the SIM868 HAT holder (secondary RTC backup).
- **Verification**: DS3231 probes at `0x68` (`UU`), its 24C32 EEPROM at `0x57`, `/dev/rtc0`
-  registered. Power-cycle test passed — after a full unplug/replug the boot log reads
-  `setting system clock to 2026-08-14…` from the RTC (was `2000-01-01` before), and
-  `hwclock -r` matches system time; the `SET TIME!` recovery line no longer appears (stable
-  oscillator on CR2032). (Debugging note: the first scans were an empty bus due to a data-line
-  wiring issue, resolved during re-soldering.) SIM868 HAT RTC was also set to the correct time
-  via `AT+CCLK` (was factory-default 2004) — its CR1220 hold will be confirmed on the next
-  power cycle.
-
-### BUG-17 — Server trip timestamps wrong after an offline period
- **Status**: `CLOSED` 2026-08-14
- **Commit**: `bf4f3d3`
- **Fix**: root cause was BUG-18 — no RTC, so offline the Pi ran on a stale `fake-hwclock`
-  time and NTP snapped the clock forward mid-trip. Fixed by installing the DS3231 (BUG-18).
- **Verification**: RTC power-cycle test passed (BUG-18). Historical trips 25136/25137 keep
-  their bad timestamps (raw tracking rows were recorded with a wrong clock and can't be
-  retroactively corrected) — future trips will be correct.
-
-### BUG-15 — Phone can't host the hotspot and connect to the Pi's AP at once
- **Status**: `CLOSED` 2026-08-13
- **Commit**: `ab79820`
- **Resolution**: Confirmed a **phone-OS limitation**, not a Pi bug. A single phone
-  can't cleanly be both the Pi's internet uplink (hotspot/AP host) and its WiFi client
-  (on the Pi's AP) at the same time — doing so routes the hotspot's traffic back through
-  the no-internet AP, creating a routing loop (`NameResolutionError` on uploads).
- **Workaround (documented)**: the phone must be **LTE-only** (WiFi off) to serve as the
-  Pi's uplink. Reach the Pi UI from that phone over the hotspot at
-  `http://<pi-hotspot-ip>` (Settings → "In-car hotspot"), or from a second device on the AP.
- **Pi-side hardening shipped**: `phone-hotspot` profile forces public DNS
-  (`8.8.8.8`/`1.1.1.1`), and the Settings page surfaces the correct URL per uplink mode.
-
-### BUG-16 — Trip missing from Pi local history (present on server)
- **Status**: `CLOSED` 2026-08-13
- **Commits**: `e5ac14e`, `f5f20c3`
- **Fix**: two root causes:
-  1. `connect_obd()` set `_car_ever_connected` **without a `global` declaration**, so the
-     module-level flag was never set and `was_car_ever_connected()` always returned `False` —
-     local trip building had been silently blocked ever since BUG-10 landed. Added the `global`
-     declaration and now persist the flag to the settings table (`car_ever_connected`) so it
-     survives reboots.
-  2. Speed-only rows (NULL GPS, from FEAT-12) made trips start/end with NULL coordinates,
-     violating the `trips.*GPSX NOT NULL` constraint. The trip builder now uses the first/last
-     GPS-bearing row for start/end coordinates, and skips a trip that never got any fix.
- **Verification**: backfilled the persisted flag on the Pi (the car has been connected
-  before), triggered a rebuild — the local `trips` table now contains the 2026-08-13 drive
-  (e.g. a 48.5 km trip) plus several earlier trips that had been silently dropped.
-  `trip_build_state` advanced to LAST_TRACKING_ID=7009. Timestamps for the 08-13 data are
-  still wrong — that's BUG-17 (no RTC).
-
-### BUG-13 — Server Web UI shows raw coordinates instead of geocoded location on trips
- **Status**: `CLOSED` 2026-08-12
- **Commit**: `8309819`
- **Fix**: Server `_geocode_cached()` now always returns a non-empty string with
-  coordinate fallback when Nominatim/reverse_geocoder fail. `/api/geocode` always
-  returns HTTP 200 with `{label}` (never 204). Batch endpoint includes all keys.
-  Nominatim params + reverse_geocoder mode aligned with Pi. Pi also hardened against
-  empty reverse_geocoder label.
- **Verification**: Deployed to Unraid (Docker rebuild) and Pi (git pull + restart).
-  Both healthy. Unraid now uses SSH deploy key for git fetch (was failing on HTTPS auth).
-
-### BUG-14 — Geocode slow/unreliable — location labels fail to load during scrubbing
- **Status**: `CLOSED` 2026-08-12
- **Commit**: `0ddfe39`
- **Fix**: Ditched Nominatim entirely — it was slow (1 req/sec rate limit, ~4s
-  timeouts) and often blocked/throttled from Docker/Cloudflare IPs. Replaced with
-  reverse_geocoder exclusively: an offline Python library that maps lat/lon →
-  city/province instantly with no network. JS `preload()` switched from N individual
-  GET requests to single `POST /api/geocode/batch`. Server batch endpoint simplified
-  to sequential loop with lru_cache + dedup.
- **Verification**: `POST /api/geocode/batch` returns `{"Montreal, Quebec",
-  "Longueuil, Quebec"}` instantly on Pi. Server Docker rebuilt and healthy.
-
-
-### BUG-01 — WiFi/hotspot unreachable from phone while cell data is on
- **Status**: `CLOSED` 2026-08-11
- **Fix**: Dual-radio — wlan0="yaris 911" at 10.42.0.1 (password "yaris911!"),
-  wlan1=uplink. Never touches wlan0. Phone-hotspot auto-connect on wlan1 within ~60s,
-  falls back to home-wifi. Settings page shows in-car access card.
- **Verification**: iOS + Android connect to AP, `yaris.local` resolves. Phone-hotspot
-  uplink tested: auto-connects when hotspot enabled, falls back when disabled. wlan0 AP
-  stays up throughout.
-
-### BUG-02 — Micro-USB power port on the Pi is physically damaged
- **Status**: `CLOSED` 2026-08-11
- **Fix**: Hard-wired 5V/GND directly to GPIO header — red to Pin 2 (5V),
-  black to Pin 6 (GND), bypassing the worn micro-USB port.
- **Verification**: `vcgencmd get_throttled` returns `0x0` — no undervoltage,
-  no throttling. Pi runs at full 1.2 GHz. GPS has fix.
-
-### BUG-03 — DTC/MIL codes never persisted
- **Status**: `CLOSED` 2026-08-11
- **Commit**: `e2f2314`
- **Fix**: `save_dtc_state()` persists MIL+codes each poll. `/api/dtc` falls back to
-  `get_persisted_dtc_state()` when OBD offline. Cleared codes tracked via IS_SET timestamps.
- **Verification**: Deployed to Pi, `/api/dtc` returns persisted snapshot, stats show `active_dtc: 0`.
-
-### BUG-04 — Server merges two trips into one
- **Status**: `CLOSED` 2026-08-11
- **Commit**: `96fb897`
- **Fix**: Replaced time-gap splitting with Pi's motion-aware logic: OBD > 1 km/h primary,
-  GPS >= 8m × 3 consecutive fallback, 5-min inactivity gap.
- **Verification**: Server trips cleared + recomputed. 17 trips on both Pi and server.
-
-### BUG-05 — Server route replay speed_source always "gps"
- **Status**: `CLOSED` 2026-08-11
- **Commit**: `e2f2314`
- **Fix**: `"obd" if speed > 0 else "gps"` matching Pi logic.
- **Verification**: Docker rebuild, `/health` OK LAN + Cloudflare.
-
-### BUG-11 — Dashboard GPS shows "Stale fix" while Status shows "Live fix"
- **Status**: `CLOSED` 2026-08-11
- **Commit**: `9733036`
- **Fix**: `renderGpsStatus()` now reads `status.latitude`/`status.longitude` from
-  the `/api/gps/status` response (not just socket events). Status page now uses the
-  same 30s staleness threshold (`fix_age_seconds > 30` → "Stale fix") instead of
-  calling any fix "Live" regardless of age.
- **Verification**: Deployed to Pi, dashboard GPS card now shows lat/lon coordinates
-  even when fix is stale. Both pages agree on fix status.
-
-### BUG-06 — Server timestamps are shifted (naive local time stored as UTC)
- **Status**: `CLOSED` 2026-08-11
- **Commit**: `7ce2a1e` (upload fix), manual migration on server
- **Fix**: 
-  1. `_to_tz_aware()` in `app_upload.py` converts naive SQLite timestamps to
-     TZ-aware ISO before upload (`2026-08-10 19:27:30` → `2026-08-10T19:27:30-04:00`).
-  2. One-time SQL migration on Unraid: shifted 3,593 tracking rows +4h EDT,
-     cleared deleted-trip markers, recomputed 43 trips from corrected data.
- **Verification**: Server trips now show Aug 10 at 7:27 PM / 7:58 PM (was 3:27 / 3:58).
-
-### BUG-12 — Dashboard OBD shows "—" while Status page shows correct OBD state
- **Status**: `CLOSED` 2026-08-11
- **Commit**: `91281b1`
- **Fix**: Added `/api/obd/status` endpoint. Dashboard calls `refreshObdStatus()`
-  on load + every 15s. Socket events still update in real-time. Side fix: `Number()`
-  wrap on API string lat/lon prevents crash. Socket `gps_location` now passes lat/lon
-  to `renderGpsStatus` (`a4a92cc`).
- **Verification**: Dashboard shows "Adapter only" matching Status page. GPS lat/lon
-  display correctly. Confirmed on live Pi.
-
-### BUG-02 — Micro-USB power port on the Pi is physically damaged
- **Status**: `CLOSED` 2026-08-11
- **Fix**: Hard-wired 5V/GND directly to GPIO header — red to Pin 2 (5V),
-  black to Pin 6 (GND), bypassing the worn micro-USB port.
- **Verification**: `vcgencmd get_throttled` returns `0x0` — no undervoltage,
-  no throttling. GPS has fix. Pi runs at full 1.2 GHz.
-
-### BUG-07 — Trip replay on portal sometimes does nothing
- **Status**: `CLOSED` 2026-08-11
- **Commit**: `fa93384`
- **Fix**: Full rewrite of `static/js/history.js`: unified AbortController cancels fetch
-  + all downstream rendering on trip switch; 300ms debounce prevents double-tap stacking;
-  loading spinner on map + `.table-active` row highlight give clear feedback; geocode
-  preload starts immediately before map rendering so cache is warm for the scrubber;
-  `signal.aborted` guards after every async step (route build, fitBounds, timeline init).
- **Verification**: Deployed to Pi and server. Rapid trip-switching no longer freezes.
-  Verified on both platforms 2026-08-11.
-
-### BUG-08 — No trip deletion on local Pi
- **Status**: `CLOSED` 2026-08-11
- **Commit**: `c5c478b`
- **Fix**: `deletable` macro, `window.confirmDelete`, `DELETE /api/trip/<id>`, configurable
-  `data-delete-url` in shared `history.js`. Raw tracking preserved.
- **Verification**: Trip 1967 deleted (18→17 trips), 2028 tracking rows preserved.
-
-### BUG-09 — Server trip scrubber geocoding is slow
- **Status**: `CLOSED` 2026-08-11
- **Fix**: `preloadGeocodes()` batch-fetches all unique coords (concurrency 4) on trip load.
-  `geocodePoint()` checks in-memory cache first.
- **Verification**: `preloadGeocodes` present in history.js on both Pi and server Docker container.
-
-### BUG-10 — GPS-only false trips when car not connected
- **Status**: `CLOSED` 2026-08-11
- **Fix**: `_car_ever_connected` flag in `app_obd.py`. `build_trip_summaries()` returns
-  empty list when car was never connected.
- **Verification**: Pi bench-test shows 0 trips. No OBD = no GPS-only trips.

-# yaris-obd Feature Requests
-
-Ideas and requests for **new features** (distinct from bugs, which belong in `BUGS.md`, and the
-phase-by-phase implementation history in `PLAN.md`). Use this file to record anything that should
-be built eventually but isn't an active roadmap phase yet. When a feature gets picked up, create a
-dedicated PLAN.md phase (or fold it into the relevant existing work) and mark it here.
-
-## How to use this file
-
- **One `## FEAT-XX` section per idea.** Keep numbering sequential.
- **Status field**: `IDEA` (brainstormed, not planned) → `PLANNED` (has an assigned phase) →
-  `IN PROGRESS` → `SHIPPED` (deployed + verified) or `WONTFIX`/`SUPERSEDED` as appropriate.
- **Relate to roadmap**: when a feature lands in a phase, note the phase here and drop a link back
-  here from PLAN.md so the two stay in sync.
- **Keep each entry small and one-idea-per-entry** so it's easy to pick up and scope.

-## Feature ideas
-
-### FEAT-01 — Parallel/concurrent chunked dashcam uploads
- **Status**: `IDEA`
- **Area**: `modules/app_upload.py` (Pi upload client)
- **Phase**: Phase 27
- **Requested**: noted in Phase 10 of PLAN.md as a possible future optimization; not yet requested
-  explicitly by the owner.
- **Idea**: upload multiple dashcam chunks (and/or multiple files) concurrently instead of the
-  current strictly sequential one-chunk-then-one-file at a time. Would speed up the multi-hour
-  full-backlog drain of a large local dashcam archive, at the cost of more complexity (bounded
-  concurrency, per-file state, failure handling for the individual concurrent workers).
- **Outstanding considerations**: memory budget on the Pi (~900MB, no swap — must stay streaming),
-  and whether the sequential pace is actually annoying enough in practice to justify the added
-  complexity.
-
-### FEAT-02 — QR / claim-code device pairing flow
- **Status**: `IDEA`
- **Area**: server device provisioning + Pi credential setup (Phase 25.5c)
- **Phase**: Phase 27
- **Requested**: discussed in Phase 25.5c as a possible follow-up to the manual copy/paste API-key
-  provisioning.
- **Idea**: zero-manual-copy provisioning of `YARIS_SERVER_URL` / `YARIS_DEVICE_NAME` /
-  `YARIS_API_KEY` onto the Pi — e.g. the portal shows a short-lived claim code / QR that the Pi
-  app (or owner) enters/scans once to adopt the device, instead of typing credentials by hand.
- **Outstanding considerations**: bigger scope than the current copy/paste flow; ship copy/paste
-  first, add pairing only if provisioning still feels annoying.

-### FEAT-03 — Manual start odometer fallback when OBD odometer is unavailable
- **Status**: `SHIPPED` 2026-08-11 (extended 2026-08-12)
- **Area**: Settings page, Dashboard, trip history, `modules/app_settings.py`, `modules/app_sql.py`,
-  `modules/app_trip.py`, `server/modules/db.py`, `static/js/history.js`
- **Phase**: Phase 27
- **What**: Settings page now has an "Odometer baseline (km)" field. The app stores
-  this value and computes `odometer_km = baseline + cumulative trip distance`. Dashboard
-  shows "(manual)" label when using baseline. When baseline is 0, falls back to live
-  OBD reading (the original behavior). Also appears in `/api/stats` response.
- **2026-08-12 — simulated odometer in trip history**: the trip replay scrubber now
-  shows an "Odometer" line below speed. Per-point odometer is the raw OBD value when
-  the vehicle reports one (PID 0xA6), otherwise a **continuous simulation**:
-  `baseline + Σ(prior trips' distance) + within-trip distance`. The trip-list
-  "Odometer" column uses the same continuous formula on both Pi and server (previously
-  the server hardcoded `None` and the Pi ignored the baseline). The 2013 Yaris doesn't
-  report PID 0xA6, so every point uses the simulated value.
-
-### FEAT-04 — Replace SIM868 2G GSM hat with 4G LTE modem (Huawei E3372h-153)
- **Status**: `IDEA`
- **Area**: modems / uplink (Pi `modules/app_cellular.py`, `modules/app_gps.py`, uplink
-  switching) — replaces the current SIM868 GSM/GNSS HAT + cellular fallback path
- **Phase**: Phase 27
- **Requested**: owner — just purchased a Huawei **E3372h-153 4G LTE Modem**. The 2G/3G-only
-  SIM868 hat will not work in Canada (2G networks are decommissioned), so the plan is to make the
-  4G modem the working cellular uplink instead.
- **Idea**: integrate the Huawei E3372h-153 as the primary cellular data uplink, replacing reliance
-  on the SIM868's GSM (AT+HTTP) path. The E3372h-153 is a USB "stick" modem — likely supported via
-  Realtek / cdc_ether / usb-storage based drivers and exposes a dial-up or LTE dongle interface the
-  Pi can use for connectivity (e.g. via NetworkManager / ModemManager, or a static APN config).
- **Outstanding considerations**:
-  - Determine the E3372h-153's local mode vs stick/dial mode and the correct Linux driver/interface
-    (hierarchical USB mode switching may be needed; it's the "153" variant which may use the RNDIS /
-    ECM / CDC-NCM profile).
-  - Whether to run it as the *primary* uplink or just another option in the existing phone-hotspot /
-    home-wifi / local-AP priority chain.
-  - What happens to the SIM868 — keep it purely for its **GPS/GNSS** role (it's the PWRKEY-toggled
-    GNSS receiver on `/dev/serial0`) while dropping its **2G GSM** cellular path, vs removing it
-    entirely.
-  - The SIM868's `app_gps.py` GNSS positioning must keep working (it's the car's GPS source) even if
-    the 2G-modem half is retired — separate the two concerns.
-  - **Keep this feature as-is (2G/GSM fallback) for countries where 2G/3G still works** — don't
-    remove the existing cellular fallback code; gate it so the 2G path remains available there.
-  - LTE SIM plan/APN specifics for Canadian carriers (Rogers/Bell/Telus) and whether the modem can
-    run the Pi's hotspot/SSID the same way `app_network.py` currently does.
-
-### FEAT-05 — DTC history synced to remote server with code descriptions
- **Status**: `SHIPPED` 2026-08-12
- **Area**: `modules/app_upload.py`, `server/sql/migrate_phase27_dtc.sql`, `server/modules/db.py`, `server/app.py`, `server/templates/dtc.html`
- **Phase**: Phase 27
- **What**: Pi pushes current DTC snapshot to server via `POST /api/v1/dtc/batch`.
-  Server diffs against stored state — new codes inserted, existing updated, missing
-  codes auto-cleared. Portal has a new `/dtc` page showing code, description, MIL
-  state, active/cleared status, first/last seen timestamps, and manual delete.
-  Upload skips when OBD disconnected (avoids clearing server DTCs on Pi reboot).
-  Snapshot is hash-compared to avoid redundant uploads.
-
-### FEAT-06 — Trip ID column in history table
- **Status**: `SHIPPED` 2026-08-11
- **Area**: `static/js/history.js`, `templates/history.html`, `server/templates/history.html`
- **Phase**: Phase 26
- **What**: Narrow `#ID` column on server history (hidden on Pi via `data-show-id`).
-  Checkbox column and batch-delete restored on server only.
-
-### FEAT-07 — Phone-hotspot auto-connect documentation
- **Status**: `SHIPPED` 2026-08-11 (already implemented in Phase 22, documented here)
- **Area**: `deploy/yaris_uplink.py`, Settings page, netwatch timer
- **What**: The Pi auto-connects to a saved phone hotspot on wlan1 within ~60s of it
-  appearing in range, and falls back to home-wifi when it disappears. The wlan0 AP
-  stays up regardless. Test flow: Settings → save hotspot name + password → "Wait for
-  hotspot" → enable phone hotspot → verify mode changes to "Phone hotspot".
- **Known limitation (2026-08-12)**: the phone can't host the hotspot *and* connect to
-  the Pi's AP at the same time — that creates a WiFi-sharing/routing loop and the Pi
-  loses internet (`NameResolutionError` on uploads). To use the phone hotspot as the
-  Pi's uplink, the phone must be LTE-only (WiFi off). Browse the Pi UI from a second
-  device on the AP instead. Also, the phone's DHCP DNS was flaky for the `.dev` tunnel,
-  so `phone-hotspot` now forces `8.8.8.8` + `1.1.1.1` (see `deploy/yaris_uplink.py`).
-
-### FEAT-08 — Predictable IP on phone hotspot (DHCP client-id)
- **Status**: `SHIPPED` 2026-08-11 (Phase 22)
- **Area**: `deploy/yaris_uplink.py`, phone-hotspot NM profile
- **What**: `dhcp-client-id=yaris-obd` in the NM keyfile gives the Pi a consistent DHCP
-  lease. The "Last phone IP" link on Settings shows the current address. Pixel testing
-  confirmed same IP across disconnects.
-
-### FEAT-09 — mDNS (yaris.local) on phone hotspot
- **Status**: `WONTFIX` 2026-08-12 — hardware/OS limitation
- **Area**: Avahi, phone-hotspot NM profile
- **What**: Phone hotspot hosts (Android, iOS) don't relay multicast DNS. Avahi publishes
-  correctly on wlan0 AP and home WiFi. Settings "Last phone IP" link is the workaround.
-  Cannot be fixed in software — this is a phone-OS limitation.
-
-### FEAT-10 — Home Assistant integration
- **Status**: `IDEA`
- **Area**: `modules/app_homeassistant.py` (new), `server/` (API endpoints), Pi-side MQTT/HTTP
- **Phase**: unassigned
- **Requested**: owner — wants the car's live telemetry and status visible in Home Assistant
-  dashboards alongside other smart-home devices.
- **Idea**: expose yaris-obd data (speed, RPM, coolant temp, fuel level, GPS position, DTC
-  alerts, ignition state, trip stats, cellular signal, etc.) as Home Assistant entities so
-  they appear automatically via MQTT discovery or a REST-based integration. The Pi already
-  collects all this data — the integration just needs to publish it in a format Home
-  Assistant can consume.
- **Possible approaches** (to scope later):
-  - **MQTT discovery**: Pi publishes to a local MQTT broker (e.g. Mosquitto on the same
-    network or on the HA host) with Home Assistant's auto-discovery topic schema
-    (`homeassistant/sensor/yaris/.../config`). HA picks up the entities automatically with
-    zero manual YAML. Works well on home WiFi; not available on phone hotspot or cellular.
-  - **REST API integration**: a custom Home Assistant integration (HACS or core) that polls
-    the Pi's `/api/stats` (or a new `/api/v1/ha/state` endpoint on the server) periodically.
-    Works from anywhere the server is reachable, including remotely via the self-hosted
-    server.
-  - **Hybrid**: MQTT when on home WiFi (real-time, low-latency), REST via server as a
-    fallback for remote/cellular visibility.
- **Entity ideas**:
-  - `sensor.yaris_speed` (km/h), `sensor.yaris_rpm`, `sensor.yaris_coolant_temp` (°C)
-  - `sensor.yaris_fuel_level` (%), `sensor.yaris_odometer` (km)
-  - `device_tracker.yaris_location` (lat/lon from GPS)
-  - `binary_sensor.yaris_ignition` (on/off), `binary_sensor.yaris_mil` (check engine light)
-  - `sensor.yaris_dtc_count`, `binary_sensor.yaris_dtc_active` (any active DTCs)
-  - `sensor.yaris_cellular_signal` (dBm or %), `sensor.yaris_uplink_mode` (home/phone/cell)
-  - `sensor.yaris_trip_distance`, `sensor.yaris_trip_duration` (current trip)
-  - `device_tracker.yaris_phone_hotspot` (when connected via phone hotspot — confirms car
-    is near the phone)
- **Outstanding considerations**:
-  - MQTT path only works when the Pi is on the same LAN as Home Assistant (home WiFi) — not
-    in the car on its own AP or cellular. This may be fine for "car is home" use cases
-    (charging status, maintenance reminders, trip summaries after returning).
-  - REST path via the self-hosted server works remotely but adds latency and depends on the
-    server being up.
-  - Decide whether to publish directly from the Pi or from the server (server already has
-    post-upload trip data; Pi has real-time data the server doesn't).
-  - Home Assistant OS vs container vs core install — MQTT discovery is universal, REST
-    would need a custom component or HACS add-on.
-  - Keep the integration opt-in and lightweight — don't add MQTT dependencies to the core
-    app.py startup unless the user explicitly configures it.
-
-
-### FEAT-11 — Hotspot SSID/password settings + 5GHz WiFi role swap
- **Status**: `SHIPPED` 2026-08-12
- **Area**: `app.py`, `templates/settings.html`, `static/js/settings.js`,
-  `deploy/yaris-hotspot.sudoers`, `deploy/yaris_uplink.py`, `deploy/install_netwatch.sh`,
-  `modules/app_network.py`
- **Phase**: Phase 27
- **What**: Two related changes:
-  1. **Hotspot settings UI** — the Pi Settings page "In-car access" card now has SSID +
-     password fields (password write-only). `GET /api/hotspot` reads the current SSID via
-     nmcli; `POST /api/hotspot` updates SSID/password and restarts the AP immediately.
-     Backed by `deploy/yaris-hotspot.sudoers` (privileged nmcli on the `Hotspot-local`
-     profile).
-  2. **WiFi role swap** — the fast TP-Link T3U (wlan1) now hosts the in-car AP on **5GHz**
-     ("vroom vroom yaris de course" at 10.42.0.1) for fast phone access (Android dev, video
-     browsing); the weak onboard BCM43438 (wlan0) carries the internet uplink (home WiFi
-     "BuzzBis" + phone hotspot, static IP 192.168.50.220). This was done because the AP on
-     the onboard radio was too slow for interactive Android work. Tradeoff: away-from-home
-     uploads now run over the weak radio (accepted — background task). A single radio cannot
-     be AP + client at once, so the phone-hotspot uplink must stay on wlan0.
- **Files**: `yaris_uplink.py` (PRIMARY=wlan0, AP_INTERFACE=wlan1, AP_CONNECTION=Hotspot-local),
-  `app_network.py` (uplink on wlan0, AP on wlan1), `install_netwatch.sh` (rebinds profiles).
-
-
-### FEAT-12 — Log OBD speed before GPS fix (rolling-start capture)
- **Status**: `SHIPPED` 2026-08-13
- **Area**: `modules/app_sql.py` (`_log_loop`, `insert_tracking`), `modules/app_trip.py`
-  (`normalize_tracking_rows`, `_segment`, `route_points`)
- **What**: The tracking logger previously only wrote rows once GPS had a fix, so a rolling
-  start or mid-drive reboot lost the first ~1.5–2 min of movement (boot + GPS cold start).
-  Now, while GPS has no fix but OBD speed > 1 km/h, the logger writes speed-only rows with
-  NULL coordinates; trip building treats them as OBD-motion events (zero GPS distance). The
-  route polyline drops these rows (no position to draw).
- **Server parity note**: server `compute_trips_for_device` and `get_trip_route` already filter
-  `gps_lat IS NOT NULL`, so they safely ignore the NULL-coordinate rows — but the server's
-  recomputed trips don't yet include the speed-only leading motion (follow-up if needed).
-
-
-### FEAT-13 — Flush uploaded tracking rows from local DB
- **Status**: `IDEA`
- **Area**: `modules/app_sql.py` (`tracking` table), `modules/app_upload.py`
- **Phase**: unassigned
- **What**: The local SQLite `tracking` table keeps every raw row forever — rows are only
-  marked `UPLOADED=1`, never deleted. Once rows are confirmed uploaded to the server, provide
-  a way to flush them locally (e.g. a settings toggle + retention window) so the local DB stays
-  bounded over years of driving.
- **Considerations**:
-  - Trip summaries (`trips` table) are derived and can be kept independently; but the local
-    route-replay polyline is built from raw `tracking` rows, so purging rows removes local route
-    detail. The server keeps full `tracking_points`, so replay stays available on the portal.
-  - Must be opt-in and only delete rows that are `UPLOADED=1` (and older than a grace window)
-    so a failed upload or re-send never loses data.
-  - Tracking data is small (~90 B/row, ~a few MB/month) so this is long-term hygiene, not
-    urgent — imported dashcam videos are the real disk consumer.
-
-
-### FEAT-14 — Second T3U to replace onboard wlan0 (dual AC radios)
- **Status**: `SHIPPED` 2026-08-14
- **Area**: hardware + `deploy/yaris_uplink.py`, `deploy/install_netwatch.sh`, `modules/app_network.py`, `deploy/90-yaris-uplink`
- **Phase**: Phase 29
- **What**: Owner added a second TP-Link Archer T3U (RTL8812BU) to replace the onboard
-  BCM43438 as the internet uplink. Both radios are now AC1300 T3U dongles — `wlan1` (T3U #1)
-  hosts the 5GHz in-car AP, `wlan2` (T3U #2) carries the uplink (home-wifi + phone-hotspot),
-  and the onboard `wlan0` is retired to a weak fallback. Removes the old tradeoff where
-  away-from-home uploads ran over the weak onboard radio.
- **Changes**: `PRIMARY_INTERFACE=wlan2` / `FALLBACK_INTERFACE=wlan0` / `AP_INTERFACE=wlan1`
-  in `yaris_uplink.py` + `app_network.py`; `install_netwatch.sh` rebinds `home-wifi` +
-  `phone-hotspot` to wlan2 and recreates the `home-wifi-fb` fallback on wlan0; the NM
-  dispatcher (`90-yaris-uplink`) now listens on `wlan0|wlan1|wlan2`.
- **Verified**: the second T3U enumerates as `wlan2` (rtl88x2bu) and
-  `vcgencmd get_throttled` = `0x0` (no undervoltage with both dongles powered).
- **Open item**: interface-name pinning relies on USB enumeration order; if the two T3Us ever
-  swap ports, `wlan1`/`wlan2` swap — a MAC-based udev/`.link` rule is the robust follow-up.
-
-
-### FEAT-15 — Clear DTC codes from the DTC page
- **Status**: `SHIPPED` 2026-08-13
- **Area**: `modules/app_obd.py`, `modules/app_sql.py`, `app.py`, `templates/dtc.html`
- **Phase**: Phase 29
- **What**: The Pi `/dtc` page now has a **Clear codes** button that sends OBD mode 04
-  (`CLEAR_DTC`) to the ECU and resets both the live and persisted DTC state, so codes can be
-  cleared right after a repair without a separate scanner. If the adapter isn't connected to
-  the car ECU it reports "not connected" (409), and if a fault is still physically present the
-  codes legitimately re-appear on the next sensor poll.
- **Files**: `clear_dtc_codes()` in `app_obd.py` (mode 04 + in-memory/socket reset),
-  `clear_dtc_state()` in `app_sql.py` (marks active rows `IS_SET=0`, resets `dtc_mil`),
-  `POST /api/dtc/clear` in `app.py`, and the button + confirm/status JS in `templates/dtc.html`.
-
-
-### FEAT-16 — Max-speed marker on trip replay map
- **Status**: `SHIPPED` 2026-08-15
- **Area**: `static/js/history.js`
- **Phase**: Phase 29
- **What**: when a trip's route loads, the replay map now pins the fastest point with an
-  amber circle + a permanent "Max speed: X km/h" tooltip. It uses the per-point speed (OBD
-  when available, otherwise the smoothed GPS-derived value), so it matches the trip summary's
-  `max_speed_kmh`. Works identically on the Pi and the server portal (shared `history.js`).

-#   gradlew start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh gradlew
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#

-# yaris-obd Android Companion App — Implementation Plan
-
-Native Android (Kotlin + Jetpack Compose) companion app for the yaris-obd Pi system.
-Primary goal: dashcam file relay (download from Pi over hotspot WiFi → upload to remote
-server over cellular, simultaneously) — the one thing the web UI cannot do (see main
-PLAN.md Phase 11/12 for the platform limitation backstory).
-
-This file is the ground-level implementation plan. The high-level architecture, API
-surface, and scope decisions live in the main `PLAN.md` (Phase 28). This file tracks
-day-to-day progress, per-sub-phase implementation details, and working notes specific
-to the Android codebase.
-
-## Dev environment
-
- **IDE:** Android Studio (Ladybug or newer) on Fedora dev machine
- **Language:** Kotlin 2.x, JDK 17 (Android Studio bundled)
- **Build:** Gradle with Kotlin DSL, version catalog (`gradle/libs.versions.toml`)
- **Emulator:** API 35 AVD, 4GB RAM, 2GB storage — UI/flow testing only (single virtual
-  NIC, can't test dual-network binding)
- **Real device:** owner's Pixel, USB debugging enabled — required for dual-network tests
- **Repo:** `android/` at project root, part of the same `yaris-obd` git repo
-

-## Sub-phases
-
-### 28.1 — Scaffold + networking proof-of-concept ✅ DONE (gate passed 2026-08-12)
-
-#### 28.1.1 — Project creation
- [x] Create Android project in `android/` via Android Studio (Empty Activity + Compose)
- [x] Kotlin DSL build files with version catalog
- [x] `.gitignore` for Android (`*.iml`, `.gradle/`, `build/`, `local.properties`, `.idea/`)
- [ ] Verify project builds and runs on emulator (needs Android Studio)
- [x] Commit: `f1c83a2` init: android project scaffold
-
-#### 28.1.2 — Networking layer
- [x] Add dependencies: OkHttp 4.12, Retrofit 2.11, Kotlinx Serialization 1.7.3
- [x] Create `NetworkBinder.kt` — discovers WiFi (Pi hotspot) + cellular networks (kept for future use)
- [x] Create Retrofit service interfaces (`PiApi.kt`, `ServerApi.kt`) with placeholder endpoints
- [x] Create DTOs: `GpsStatus`, `HealthResponse`
- [x] Wire `DualNetworkTestScreen.kt` with real OkHttp calls + simultaneous "Test Both" button
- [x] Wire `MainActivity.kt` — simplified to single OkHttpClient, OS routes correctly
- [x] **Real-device gate test — PASSED 2026-08-12 on Pixel:**
-  - "Test Pi" → `✓ Pi OK (200)` with live GPS fix data
-  - "Test Server" → `✓ Server OK (200) — {"status":"ok"}`
-  - "Test Both Simultaneously" → `✓ BOTH NETWORKS WORK SIMULTANEOUSLY`
-  - Key finding: per-socket `Network.bindSocket()` not needed — Android OS routes
-    `10.42.0.1` through WiFi and `yaris.ceaf.dev` through cellular automatically
- [x] Commit: `348bfdc` feat: Phase 28.1 gate passed
-
-#### 28.1.3 — Credential storage
- [ ] Add EncryptedSharedPreferences for server URL, device name, API key
- [ ] First-launch screen: text fields for server URL, device name, API key
- [ ] "Test connection" button on credentials screen (calls `/health` on server)
- [ ] Persist credentials after successful test
- [ ] Commit: `feat: encrypted credential storage + first-launch flow`
-
-### 28.2 — Dashcam browser + download ✅ DONE (2026-08-12)
-**Depends on: 28.1 (networking layer + credentials).**
-
-#### What was built
- **Pi API extension** (`PiApi.kt`): `listVideos()` → `VideoListResponse`, `getVideoFile()`
-  (streaming `ResponseBody`), `getThumbnail()` (JPEG bytes), `deleteVideo()`
- **DTOs:** `VideoListResponse`, `VideoFile` (relative_path, size, mtime, sha256, uploaded,
-  thumbnail_url), `ConvertProgress`
- **DashcamScreen:** `LazyColumn` of imported Pi videos with thumbnails via Coil async image
-  loader, file size, date, upload status badge (Uploaded/Pending)
- **DashcamViewModel:** manages video list state, download to phone storage, delete local copy,
-  conversion progress polling
- **Downloads via WorkManager:** `DownloadWorker` foreground service with notification +
-  `setProgressAsync()` for inline progress bar. `ActiveDownload` state tracked via WorkManager
-  `LiveData` observation. Survives screen lock / background. FGS type declared as
-  `FOREGROUND_SERVICE_TYPE_DATA_SYNC` for Android 14+.
- **Downloads tab:** progress bar + % for in-flight downloads, downloaded files list
- **Bottom navigation:** Dashcam tab + Test tab
- **Verified:** video list loads from real Pi over "yaris 911" hotspot on the owner's Pixel
-
-#### Commits
- Phase 28.2 — dashcam video browser + WiFi download
- fix: downloads use WorkManager foreground service + inline progress
-
-### 28.3 — Cellular upload 🚧 IN PROGRESS (2026-08-12)
-**Depends on: 28.2 (files on phone local storage).**
-
-#### 28.3.1 — Server upload data layer ✅ DONE
- [x] Retrofit interface for server chunked upload (`data/remote/ServerApi.kt`):
-  - `GET /api/v1/dashcam/upload/status?sha256={hash}` → `UploadStatus`
-  - `POST /api/v1/dashcam/upload/chunk` → multipart (file chunk, sha256, chunk_index, total_chunks)
- [x] Data classes: `UploadStatus` (already_uploaded, received_chunk_indices, total_chunks)
-
-#### 28.3.2 — Upload worker ✅ DONE
- [x] WorkManager `CoroutineWorker` (`UploadWorker.kt`):
-  - Input: filename, server URL, device name, API key
-  - Step 1: compute SHA256, check `/status` for already-received chunks
-  - Step 2: read file in 40MB chunks (matching `DASHCAM_CHUNK_SIZE`)
-  - Step 3: POST each missing chunk (skips already-received chunks)
-  - Step 4: verify server reports `already_uploaded` after last chunk
- [x] Foreground service notification with live % ("Uploading VID_00234.MOV — 62%")
- [x] Byte-level upload progress via `ProgressRequestBody` (okio `ForwardingSink`) — progress
-  reflects actual bytes sent including already-received chunks, not just chunk count
- [x] Robust chunk reads (loop `skip()`/`read()` instead of single calls)
- [x] Debug logging (`Log.d`/`Log.e`, tag `UploadWorker`) throughout
- [x] Re-upload guard: skips files already on server (`already_uploaded`)
-
-#### 28.3.3 — Upload queue UI ✅ DONE (2026-08-15)
- [x] Downloads screen shows per-file upload status + inline progress bar
- [x] In-app test file generator for upload testing
- [x] "Upload all" button → enqueue all pending files (header card, shows pending count)
- [x] Retry button per failed file (tracks failed uploads via `failedUploads` StateFlow)
- [x] Commit: `feat: upload queue screen — upload all + per-file retry`
-
-### 28.4 — Live dashboard ✅ DONE (2026-08-15) — MapLibre map deferred
-**Depends on: 28.1 (networking layer). Independent of 28.2/28.3.**
-
-#### 28.4.1 — Data layer ✅
- [x] Retrofit interface additions to `PiApi`:
-  - `GET /api/gps/status` → `GpsStatus` (has_fix, lat, lon, fix_age_seconds, thread_alive)
-  - `GET /api/obd/status` → `ObdStatus` (adapter_present, port, car_connected, speed, rpm,
-    coolant_temp, fuel_level, throttle_position, mil_on)
-  - `GET /api/stats` → `Stats` (trip_count, total_km, active_dtc, video_count, odometer_km)
- [x] Polling scheduler: `DashboardViewModel` with `startPolling()`/`stopPolling()` — fetches
-  immediately then every 2s; stopped via `DisposableEffect` when the tab loses focus.
- [x] Server `/health` check (cellular) alongside Pi polling for the connection bar.
-
-#### 28.4.2 — Dashboard UI ✅ (map deferred)
- [x] Speed card: large number (km/h), "OBD speed"/"OBD offline" source label
- [x] RPM card: number with color scale (green < 3000, amber < 5000, red ≥ 5000)
- [x] Engine stats row: coolant temp (°C), fuel level (%), throttle (%)
- [x] MIL/DTC card: check-engine warning (amber = MIL on, green = no MIL) + stored DTC count
- [x] GPS card: fix status, lat/lon, fix age, thread alive (text — MapLibre map deferred)
- [x] Overview card: trips, total km, all-time max speed, videos, DTCs, odometer
- [x] Connection status bar: Pi WiFi dot + Server dot (green = online), last-update timestamp
- [x] Auto-refresh every 2s; polling stops when navigating away from the tab
- [ ] GPS map (MapLibre) — deferred: needs the MapLibre dep + basemap over hotspot (no internet).
-
-### 28.5 — Trip history ✅ DONE (2026-08-15)
-**Depends on: 28.1. Independent of 28.2–28.4.**
-
-#### 28.5.1 — Data layer ✅
- [x] Retrofit interface additions to `PiApi`:
-  - `GET /api/trips` → `TripsResponse` (list of `TripSummary`)
-  - `GET /api/trip/{id}` → `TripRoute` (metadata + route points with lat/lon/speed/source)
-  - `GET /api/geocode?lat&lon` → `GeocodeResult`
-  - `POST /api/geocode/batch` → `Map<String,String>` (one call for all start/end labels)
- [x] `TripViewModel`: `loadTrips()` (with batch geocode of start/end), `loadRoute(id)`, `clearRoute()`
- [ ] Room cache (trip list + last route for offline) — deferred; Pi is the live source
-
-#### 28.5.2 — Trip list UI ✅
- [x] `LazyColumn` of trips: date, start→end time, distance, duration, avg/max speed, start→end labels
- [x] Tap → opens `TripReplayScreen`
- [x] Newest first (Pi returns newest-first)
-
-#### 28.5.3 — Route replay UI ✅
- [x] MapLibre `MapView` with the Pi's offline raster tiles (`/static/vendor/tiles/{z}/{x}/{y}.png`, zoom 8–15) — works with no internet
- [x] Route polyline (GeoJsonSource + LineLayer) + cursor circle marker, camera fit to bounds
- [x] Timeline scrubber (Slider) with timestamp + speed label
- [x] Play/pause button animating the cursor along the route (~5 fps)
- [x] Trip stats header: distance, duration, avg speed, max speed
- [x] System back button returns from replay to the list (BackHandler)
- [ ] Start/end markers + geocode label below scrubber — deferred
-
-### 28.6 — Remote portal direct access ✅ DONE (2026-08-15)
-**Depends on: 28.1 (credentials). Independent of 28.2–28.5. Stretch goal.**
-
-#### 28.6.1 — Auth + data layer ✅
- [x] `PortalApi` (Retrofit) for the server portal:
-  - `GET /api/v1/portal/stats` → `PortalStats`
-  - `GET /api/v1/portal/trips` → `List<PortalTripSummary>` (mapped to shared `TripSummary`)
-  - `GET /api/v1/portal/trip/{id}` → `TripRoute` (reuses `RoutePoint`)
-  - `GET /api/v1/portal/dashcam` → `List<PortalDashcamFile>`
-  - `GET/POST /api/geocode` + batch (server-side reverse geocoder)
- [x] `PortalViewModel` with CSRF form login (`GET /login` → parse token → `POST /login`)
-      + in-memory `CookieJar` for the Flask session cookie, 401 → auto "session expired"
- [x] Portal credentials (username/password) stored in `CredentialStore` (SharedPreferences);
-      auto-login on launch when present
- [ ] Dashcam video streaming/player — deferred (list only for now)
-
-#### 28.6.2 — Portal screens ✅
- [x] New "Server" tab: login form → overview stats + trip list + dashcam archive
- [x] Reuses `TripCard` + `TripReplayScreen` from 28.5 (server serves the same route shape)
- [x] "Connected to server" indicator + server URL + logout
- [x] Tapping a server trip opens the same replay screen with an online CartoDB basemap
-      (`PORTAL_TILE_URL`, zoom 0–19) so it works over cellular away from the hotspot
- [ ] Video playback (stream endpoint) — deferred
-
-### 28.7 — UI redesign: match the mobile web UI ✅ DONE (2026-08-15)
-**Depends on: 28.1–28.6. Renumbers the old 28.7 (polish) to 28.8.**
-
-#### 28.7.1 — Theme
- [x] Light theme matching `static/yaris.css`: content bg `#f4f6fb`, white cards,
-      primary `#4e73df`, accent/error red `#e63946`, text-muted `#6c757d`
- [x] App defaults to light (matches the web; the web has no dark mode)
-
-#### 28.7.2 — Chrome (top bar + bottom nav)
- [x] Global dark top bar (`YarisHeader`): `#1c1c1e`, white italic "YARIS-OBD"
-      wordmark + red underline, status-bar aware
- [x] Dark bottom `NavigationBar` (`#1c1c1e`, white active / 55% white inactive)
-      mirroring the web's `.mobile-bottom-nav`
- [x] Removed the per-screen `YarisHeader` in favour of the one global top bar
- [x] Trip replay screen gets the same dark top bar
-
-#### 28.7.3 — Component polish (follow-up)
- [ ] Card shadows (`shadow-sm`) + white card surfaces
- [ ] Blue primary buttons (`btn-primary` #4e73df)
- [ ] FontAwesome-style icons where they map to the web nav
- [ ] Page titles (`h3 fw-bold`) at the top of each screen
-
-### 28.8 — Polish + distribution 🚧 IN PROGRESS
-**Depends on: 28.1–28.7 (whichever subset ships).**
-
-#### 28.8.1 — App polish ✅ (2026-08-15)
- [x] App icon: adaptive icon (red `#e63946` bg + white gauge foreground)
- [x] Splash screen: native API 31+ (`values-v31/themes.xml`, dark bg + gauge icon)
- [x] Dark theme follows the OS setting (done in 28.7)
- [x] App label: "Yaris OBD"
- [ ] Error handling audit — most screens have error states; dashboard still shows "—" when offline
- [ ] Accessibility audit — content descriptions present on most icons; touch targets ≥48dp mostly
-
-#### 28.8.2 — Build + distribution ✅ (2026-08-15)
- [x] Release signing key: `android/keystore/release.keystore` (gitignored) + `keystore.properties`
- [x] ProGuard/R8 rules verified — release APK builds AND launches on the Pixel
- [x] APK output: `app/build/outputs/apk/release/app-release.apk` (~43 MB, signed)
- [x] Self-hosted distribution (server → Pi → phone):
-  - Server: `GET /api/v1/app/latest` (public version+sha256) + `GET /app/yaris-obd.apk`
-    (download) + `GET/POST /app/upload` (portal page to publish a build)
-  - Pi: `GET /app` (download page) + `GET /app/yaris-obd.apk`; `deploy/yaris_app_updater.py`
-    mirrors the latest APK from the server on a systemd timer
-    (`deploy/yaris-app-updater.{service,timer}` + `deploy/install_app_updater.sh`)
-  - Phone: connect to hotspot → `http://10.42.0.1/app` → download → install
- [x] Deployed 2026-08-15: `install_app_updater.sh` run on the Pi (timer active, APK 0.1.0
-      mirrored), server rebuilt with the app endpoints, and the release APK published to the
-      server's mounted `dashcam/app/` volume.
-
-## Working notes
-
-### Dual-network binding reference
-
-The key mechanism — from the Android docs and the Phase 11 investigation:
-
-```kotlin
-val connectivityManager = context.getSystemService<ConnectivityManager>()
-
-// Find the WiFi network (connected to Pi hotspot)
-val wifiNetwork: Network? = connectivityManager.allNetworks
-    .firstOrNull { network ->
-        val caps = connectivityManager.getNetworkCapabilities(network)
-        caps?.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) == true &&
-        caps?.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET) == false
-        // Pi hotspot has no internet — we WANT this network for local API calls
-    }
-
-// Find the cellular network
-val cellNetwork: Network? = connectivityManager.allNetworks
-    .firstOrNull { network ->
-        val caps = connectivityManager.getNetworkCapabilities(network)
-        caps?.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) == true
-    }
-
-// Create OkHttp clients bound to specific networks
-fun OkHttpClient.bindToNetwork(network: Network?): OkHttpClient {
-    if (network == null) return this
-    return newBuilder()
-        .socketFactory(network.socketFactory)
-        .dns { network.getAllByName(it) }
-        .build()
-}
-```
-
-The two clients then share nothing — different socket factories, different DNS resolvers —
-fully independent network paths.
-
-### Pi hotspot info
-
- SSID: "yaris 911" (WPA2-PSK)
- Subnet: `10.42.0.0/24`
- Pi IP: `10.42.0.1`
- mDNS: `yaris.local` (may not resolve on phone hotspot — documented limitation)
- App should use IP `10.42.0.1` directly, not rely on mDNS
-
-### Chunked upload protocol (reused from Phase 10)
-
- Chunk size: 40MB (well under Cloudflare's 100MB free-tier limit)
- `/status?sha256=...` returns `{already_uploaded: true}` or `{received_chunk_indices: [0,1,3], total_chunks: 8}`
- `/chunk` POST: multipart with `file` (binary chunk), `sha256`, `chunk_index` (0-based), `total_chunks`
- Server reassembles when all chunks received, verifies SHA256, records in Postgres
- Entirely deduplicated by SHA256 — safe to re-upload chunks, server ignores duplicates
-

-### Real-device testing workflow
-
-1. Build debug APK: `./gradlew assembleDebug`
-2. Install on Pixel: `adb install app/build/outputs/apk/debug/app-debug.apk`
-3. Connect phone to Pi hotspot
-4. Confirm cellular data toggle is ON (Android should show both WiFi and LTE icons)
-5. Run the app → check dual-network test screen
-6. For upload tests: temporarily pause the Pi's own background uploader
-   (Settings → "Upload dashcam videos" toggle OFF) so the phone's upload isn't racing
-   the Pi's own uploader for the same files
-
-### Environment gotchas
-
- **Emulator networking**: the Android emulator has its own virtual router. Accessing
-  `10.42.0.1` from the emulator goes through the host machine's network stack — it won't
-  reach the Pi unless the host is also on the Pi's WiFi hotspot. Prefer real-device testing
-  for any network-dependent code.
- **Pixel "switch to mobile data automatically"**: some Android versions have a setting
-  that auto-disables WiFi if it detects no internet. On the Pi hotspot (which has no
-  internet), this could silently drop the WiFi connection. The Phase 11 testing already
-  confirmed this is a hard platform limitation for the web UI; the native app's
-  `bindProcessToNetwork()` might bypass it. If the OS still kills the WiFi association,
-  the fallback is asking the user to enable "Keep WiFi on when no internet" in Developer
-  Options.
- **WorkManager + doze**: on Android 6+, WorkManager jobs may be deferred when the device
-  is in Doze mode. For uploads that the user explicitly triggered, consider using a
-  foreground service instead of (or in addition to) WorkManager so uploads continue
-  immediately.
- **40MB chunk memory**: the OkHttp `MultipartBody` will buffer each 40MB chunk in memory
-  before sending. On modern phones with 6GB+ RAM this is fine, but if it becomes an issue,
-  switch to a streaming multipart approach (OkHttp's `RequestBody` as `okio` pipe).
- **SHA256 of large files**: computing SHA256 of a 300MB file on a phone takes a few
-  seconds. Do it once when the download completes, store the result in Room, and reuse
-  for upload. Don't recompute on every upload attempt.

-#   * the `yaris` service user (with sudo + serial/GPIO groups)
-#   * repo clone at /home/yaris/app/yaris-obd

-#   * every deploy/install_*.sh in the correct order
-#
-# Run ON THE PI as root (or via sudo):

-#
-# The only questions it asks are for the WiFi credentials it needs. You can

-this particular project before. The end result is a Pi that auto-starts the
-`yaris-obd` web app on boot and serves it at `http://yaris.local` over the car's
-own WiFi hotspot, with GPS tracking, live OBD-II data, dashcam import, and
-background uploads to a self-hosted server.
-
-For the project's full phase-by-phase history and hardware bring-up notes, see
-[`PLAN.md`](../PLAN.md).

-
-## 1) Parts list
-
-| Part | Purpose | Notes |
-| --- | --- | --- |
-| Raspberry Pi 3 Model B | Runs the app, logs data, hosts the hotspot | Pi 3 B is the reference build; a Pi 3B+/4 works too |
-| Waveshare SIM868 HAT | GNSS (GPS) + optional GSM/GPRS | GSM needs a SIM and 2G coverage (often none in NA); GPS is the part in use |
-| SIM868 antennas | GSM + GPS reception | Two **separate** antennas — GSM and GNSS each plug into their own u.FL port on the HAT |
-| USB OBD-II adapter | Reads live vehicle data | PL2303-chip ELM327-compatible (USB). Appears as `/dev/ttyUSB*` |
-| 2× TP-Link Archer T3U | WiFi — `wlan1` = in-car 5GHz AP, `wlan2` = internet uplink | RTL8812BU chipset, needs a DKMS driver (the installer builds it) |
-| DS3231 RTC module | Keeps the clock correct with no internet | Optional but strongly recommended; on the I²C bus `i2c-1` |
-| CR2032 cell | Backup battery for the RTC | Must be **non-rechargeable** type for the ZS-042 board (see below) |
-| 5V power source | Powers the Pi | Either a quality USB PSU **or** a hard-wired 5V/GND feed to the GPIO header |
-| USB dashcam | Records video; files are imported over USB | Any brand that enumerates as USB mass storage |
-| SD card (≥16GB) | Pi boot + app storage | A2/U3 card recommended |
-| Car | The patient | Reference car: 2013 Toyota Yaris |

-## 2) Hardware assembly
-
-> **Safety first.** Anything mounted in a car must not interfere with pedals,
-> steering, airbags, visibility, or occupants. Route and secure every cable.
-> Never do this work while driving. If you are tapping vehicle 12V, fuse the
-> feed as close to the source as possible.
-
-### 2.1 Raspberry Pi
-
- Fit the SD card after flashing (Section 3).
- If you plan to run the Pi without a keyboard/monitor, set up SSH during
-  flashing so you can work on it headlessly.
-
-### 2.2 SIM868 HAT (GPS)
-
-The SIM868 HAT stacks on the Pi's 40-pin GPIO header.
-
-1. **Set the UART jumper to `B` (Pi ↔ SIM868).** This is the 3-position jumper on
-   the HAT: `A` = USB↔SIM868, `B` = Pi GPIO↔SIM868, `C` = USB↔Pi console. It must
-   be on **B** or the Pi cannot talk to the module.
-2. **Connect both antennas.** The **GPS/GNSS antenna** and the **GSM antenna** go
-   into their **own separate u.FL sockets** on the HAT. A GPS fix is impossible
-   with only the GSM antenna connected — this was the single most common bring-up
-   mistake in the reference build.
-3. **PWRKEY.** This HAT revision ships with the "P4" GPIO power-on mod wire
-   already installed (header pin 7 = BCM GPIO4). The app pulses it automatically
-   at boot to power the module chip on. If your board does not have that wire,
-   you must press the HAT's PWRKEY button for ~1–2s after every Pi power-up, or
-   add the mod wire yourself.
-4. Run the installer with `--with-sim868` (Section 4) so the Pi frees the full
-   UART for the HAT (`enable_uart=1`, `dtoverlay=disable-bt`, no serial login
-   shell, `hciuart` disabled). Baud rate is **115200**.
-
-### 2.3 DS3231 RTC (recommended)
-
-Without an RTC the Pi boots with a wrong clock every time the car has no internet,
-which corrupts trip timestamps.
-
-| DS3231 (ZS-042) pin | Pi GPIO header pin |
-| --- | --- |
-| VCC | **Pin 1 — 3.3V** (not 5V) |
-| GND | Pin 6 |
-| SDA | Pin 3 (I²C SDA) |
-| SCL | Pin 5 (I²C SCL) |
-
- **Remove the charge diode** on the ZS-042 board if you fit a non-rechargeable
-  CR2032 — the board's trickle-charge circuit is unsafe for non-rechargeable
-  cells.
- If `i2cdetect -y 1` shows nothing at `0x68`, your SDA/SCL are crossed or a
-  joint is cold. A lit LED only means power is present.
- Run the installer with `--with-rtc` (Section 4) to add the overlay, disable
-  `fake-hwclock`, and load the `i2c-dev` module.
-
-### 2.4 USB OBD-II adapter
-
- Any PL2303/CH340-based ELM327 USB adapter works. It enumerates as
-  `/dev/ttyUSB0` (or the first available `/dev/ttyUSB*`).
- The app auto-detects the port; you can override it later with the `OBD_PORT`
-  env var in the systemd unit if needed.
-
-### 2.5 WiFi dongles (2× T3U)
-
- Plug one T3U into each USB port. The **interface names follow USB enumeration
-  order**, so on a given Pi `wlan1` and `wlan2` are stable only as long as the
-  dongles stay in the same ports. If you ever swap ports, the AP and uplink roles
-  will swap too.
- The installer builds the RTL8812BU DKMS driver. On a Pi 3 the two identical
-  dongles are distinguished only by their position, not by MAC — a MAC-based
-  udev rule is a possible future improvement (not required for normal use).
- Expected roles:
-  - `wlan1` — hosts the in-car **AP** (5GHz, `10.42.0.1`)
-  - `wlan2` — carries the **internet uplink** (home WiFi + optional phone hotspot)
-  - `wlan0` — onboard radio, kept as a weak fallback only
-
-### 2.6 Power
-
-Two valid approaches:
-
- **Simplest:** a good 5V/2.5A+ USB PSU (the official Pi 3 PSU is ideal). Avoid
-  thin cables — voltage drop is the #1 cause of `vcgencmd get_throttled`
-  undervoltage flags.
- **Robust for permanent install (reference build):** hard-wire regulated 5V/GND
-  directly to the GPIO header — **red to Pin 2 (5V), black to Pin 6 (GND)** —
-  fed from a fused 12V→5V buck converter (≥3A) or a quality cigarette-lighter
-  USB supply. This bypasses the fragile micro-USB connector.
-
-Whichever you choose, verify after install:
-
-```bash
-vcgencmd get_throttled
-# 0x0 = no undervoltage, no throttling (what you want)
-```
-
-A non-zero current undervoltage/throttling bit means the power feed is
-inadequate and must be fixed before the unit lives in the car.
-
-### 2.7 Dashcam
-
- Any dashcam that mounts as generic USB mass storage works — the app detects USB
-  storage via `lsblk` and walks it for video files.
- **Known manual step:** many dashcams boot into a "select mode" menu (dashcam /
-  mass-storage / webcam) when they sense live USB data lines. To record, the USB
-  data lines must be absent; to import, they must be present. The project does
-  **not** switch this automatically — unplug/replug (or use a data-blocking
-  cable) when switching between recording and importing.
-
-### 2.8 Final in-car placement
-
- Keep the GPS antenna with a skyward view (dash top is usually fine).
- Keep the Pi and dongles clear of direct sunlight and away from heater vents.
- Strap everything down; a loose Pi near the pedals is a hazard.
-
---
-
-## 3) Flash Raspberry Pi OS
-
-1. Download **Raspberry Pi Imager** and write **Raspberry Pi OS Bookworm** (Lite
-   is fine) to the SD card.
-2. In Imager's advanced options (gear icon) set:
-   - hostname: `yaris`
-   - enable SSH (password or key)
-   - your primary username + password (the installer creates a separate `yaris`
-     service user; this is just for you to log in)
-   - optional: your home WiFi credentials so the Pi is reachable for the install
-3. Boot the Pi, find it on your network, and SSH in:
-
-```bash
-ssh <your-user>@yaris.local
-# or fall back to the IP if mDNS isn't working yet
-```
-
---
-
-## 4) Run the one-shot installer
-
-The installer (`deploy/auto_install.sh`) takes a fresh OS from zero to running.
-It installs packages, creates the `yaris` user, clones the repo, builds the T3U
-driver, creates the NetworkManager WiFi profiles, and runs every
-`deploy/install_*.sh` in the right order.
-
-### 4.1 Get the script onto the Pi
-
-**Option A — download it directly (recommended):**
-
-```bash
-curl -fsSL -o auto_install.sh \
-  https://raw.githubusercontent.com/quoije/yaris-obd/shameless-aislop/deploy/auto_install.sh
-```
-
-> Replace `shameless-aislop` with the repo's current default branch if it has
-> changed since this was written.
-
-**Option B — clone the repo and run from inside it:**
-
-```bash
-git clone https://github.com/quoije/yaris-obd.git
-cd yaris-obd
-# the script clones again into /home/yaris/app/yaris-obd; that is expected
-```
-
-### 4.2 Run it
-
-The only required inputs are your **home WiFi** and **in-car hotspot**
-credentials. Pass them through the environment (or let the script prompt you):
-
-```bash
-sudo -E bash auto_install.sh \
-  --with-rtc \
-  --with-sim868
-```
-
-with these environment variables set:
-
-```bash
-export HOME_WIFI_SSID="MyHomeWiFi"
-export HOME_WIFI_PSK="home-wifi-password"
-export HOTSPOT_SSID="yaris-obd"          # in-car AP; default is "yaris-obd"
-export HOTSPOT_PSK="in-car-password"
-# optional phone hotspot uplink:
-export PHONE_HOTSPOT_SSID="MyPhoneHotspot"
-export PHONE_HOTSPOT_PSK="phone-hotspot-password"
-```
-
-Fully non-interactive (no prompts) — fails if a required value is missing:
-
-```bash
-sudo -E bash auto_install.sh --non-interactive --with-rtc --with-sim868
-```
-
-### 4.3 Flags
-
-| Flag | Effect |
-| --- | --- |
-| `--with-rtc` | Enable the DS3231 RTC (I²C overlay, disable `fake-hwclock`) |
-| `--with-sim868` | Enable the SIM868 UART (`enable_uart=1`, `disable-bt`, no serial console, `hciuart` off) |
-| `--skip-t3u-driver` | Skip the RTL8812BU build (if you're not using T3U dongles) |
-| `--no-watchdog` | Skip the 10s hardware watchdog |
-| `--no-app-updater` | Skip the Android APK mirror timer |
-| `--non-interactive` | Never prompt; error out on missing credentials |
-| `-h` / `--help` | Print help |
-
-Optional env vars also honoured: `GIT_URL`, `GIT_BRANCH`, `YARIS_PASSWORD`,
-`OWNER_NAME`, `CAR_MODEL`, `DEVICE_NAME`, `YARIS_SERVER_URL`,
-`YARIS_DEVICE_NAME`, `YARIS_API_KEY`.
-
-### 4.4 What the installer does
-
-1. Installs base packages (`git`, Python tooling, NetworkManager, nftables,
-   avahi, dnsmasq-base, `iw`) and enables NetworkManager.
-2. Creates the `yaris` service user (groups: `sudo`, `dialout`, `gpio`, `i2c`).
-3. Clones the repo to `/home/yaris/app/yaris-obd`.
-4. Applies `--with-rtc` / `--with-sim868` boot-config changes if requested.
-5. Builds the RTL8812BU driver (unless skipped).
-6. Creates/updates the `home-wifi`, `Hotspot-local`, and optional `phone-hotspot`
-   NetworkManager profiles.
-7. Runs, in order: `install_service.sh`, `install_port_redirect.sh`,
-   `install_netwatch.sh`, `install_video_tools.sh`, and (unless disabled)
-   `install_watchdog.sh` + `install_app_updater.sh`.
-8. Optionally prefills `config/device.json` and `db/upload_creds.env` from env
-   vars, fixes repo ownership, and creates the writable data directories.
-
-### 4.5 Reboot
-
-If you used `--with-rtc` or `--with-sim868`, reboot so the boot-config changes
-apply:
-
-```bash
-sudo reboot
-```
-
---
-
-## 5) Verify
-
-After reboot, on the Pi:
-
-```bash
-sudo systemctl status yaris-obd.service --no-pager
-sudo systemctl status yaris-netwatch.timer --no-pager
-sudo nft list ruleset | grep -n "dport 80"
-curl -I http://127.0.0.1/
-curl -s http://127.0.0.1/api/gps/status
-```
-
-Expected:
-
- `yaris-obd.service` is `active (running)`
- `yaris-netwatch.timer` is active
- nftables redirects port `80` → `5000`
- local HTTP on port 80 returns 200/302
- `/api/gps/status` returns JSON (GPS thread alive)
-
-From another device on your home WiFi:
-
- `http://yaris.local`
-
-From a phone connected to the **in-car hotspot** (`HOTSPOT_SSID`):
-
- `http://yaris.local` — or `http://10.42.0.1` if the phone doesn't resolve mDNS
-
-If the T3U dongles don't appear after the driver build:
-
-```bash
-ip link show wlan1
-ip link show wlan2
-```
-
-If `wlan1` is missing, fix the driver first (see Section 9), then re-run
-`sudo bash deploy/install_netwatch.sh`.
-
---
-
-## 6) Configure device identity
-
-The Pi shows an owner name, car model, device name, and avatar. Either edit the
-file directly:
-
-```bash
-sudo nano /home/yaris/app/yaris-obd/config/device.json
-```
-
-```json
-{
-  "owner_name": "Your Name",
-  "car_model": "Toyota Yaris 2013",
-  "device_name": "My Yaris OBD",
-  "avatar_path": "img/yaris.png"
-}
-```
-
-or open the web UI → **Settings** and manage it there.
-
- **`owner_name`** — top-right of the topbar
- **`car_model`** — left sidebar, next to the car icon
- **`device_name`** — device identity used for remote-server sync
- **`avatar_path`** — avatar image, relative to `static/` (drop your image in
-  `static/img/` and update the path, or replace `static/img/yaris.png`)
-
-Restart after editing the file:
-
-```bash
-sudo systemctl restart yaris-obd.service
-```
-
-> **Heads-up:** the local SQLite database filename is derived from `owner_name`
-> (`db/sql/<owner_name>_<car_model>.db`). Changing `owner_name` later creates a
-> new empty database and orphans the old one — rename the old file to match if
-> you want to keep the data.
-
---
-
-## 7) Connect to the remote server (optional but recommended)
-
-Trip logs and dashcam footage upload to a self-hosted Flask + Postgres server
-(`server/` in this repo). See [`server/README.md`](../server/README.md) for
-deploying it.
-
-Once the server is up and a device is registered, put the credentials on the Pi
-either via the web UI (**Settings → Remote server credentials → Test connection →
-Sync now**) or by prefilling `db/upload_creds.env`:
-
-```bash
-sudo nano /home/yaris/app/yaris-obd/db/upload_creds.env
-```
-
-```ini
-YARIS_SERVER_URL = "https://your-server.example"
-YARIS_DEVICE_NAME = "yaris-2013"
-YARIS_API_KEY = "your-one-time-key"
-```
-
-Then enable **Sync with server** in Settings if you want the server to own the
-device identity.
-
---
-
-## 8) Daily use & updates
-
-Update the Pi to the latest code:
-
-```bash
-cd /home/yaris/app/yaris-obd
-git pull --ff-only
-sudo bash deploy/install_service.sh        # re-deploy the unit + sudoers
-sudo systemctl restart yaris-obd.service
-```
-
-If any `deploy/` files changed, re-run the matching installer(s)
-(`install_netwatch.sh`, `install_port_redirect.sh`, `install_app_updater.sh`, …).
-
-In-car, connect your phone to the hotspot and browse `http://yaris.local`.
-Dashcam files are imported from the **Dashcam** page; live telemetry is on the
-**Dashboard**; past drives are under **History**.
-
---
-
-## 9) Troubleshooting
-
-```bash
-bash /home/yaris/app/yaris-obd/scripts/diagnose.sh          # read-only check
-bash /home/yaris/app/yaris-obd/scripts/diagnose.sh --fix    # attempt auto-fix
-```
-
-Common issues:
-
-| Symptom | Likely cause | Fix |
-| --- | --- | --- |
-| `wlan1`/`wlan2` missing | RTL8812BU driver didn't build | Re-run the driver build from Section 4; check `dkms status` |
-| GPS never gets a fix | GPS antenna on wrong u.FL / not seated; HAT jumper not on `B`; SIM868 chip not powered | Re-check antennas + jumper; confirm the app pulses PWRKEY (or press the button 1–2s) |
-| Wrong time after a cold boot | No RTC or RTC not configured | `i2cdetect -y 1` should show `UU` at `0x68`; check wiring (3.3V!) |
-| `vcgencmd get_throttled` ≠ `0x0` | Weak power feed | Use a better PSU/cable, or hard-wire 5V to GPIO pins 2 & 6 |
-| Dashcam import hangs | `yaris` lacks passwordless sudo for mount/rm | Re-run `sudo bash deploy/install_service.sh` (installs `yaris-dashcam.sudoers`) |
-| Hotspot SSID/password changes don't save | `yaris-hotspot.sudoers` missing | Re-run `sudo bash deploy/install_netwatch.sh` |
-| `yaris.local` not resolving on a phone | mDNS blocked / phone doesn't relay mDNS on the hotspot | Use `http://10.42.0.1` directly |
-| `pip install -r requirements.txt` fails | Outdated checkout with the concatenated `requests-toolbeltreverse_geocoder` line | `git pull --ff-only` (fixed in current repo) |
-| SSH drops when NetworkManager is enabled (Bookworm Lite) | NM takes over the interface and has no profile for your current WiFi yet | Run the installer over **Ethernet**, or pre-create the profile before enabling NM; after the run, re-connect to your WiFi |
-
---
-
-### Manual reference: the installers
-
-`auto_install.sh` is just a wrapper around these individual scripts, which you can
-also run by hand from `/home/yaris/app/yaris-obd`:
-
-```bash
-sudo bash deploy/install_service.sh        # systemd unit + venv + sudoers
-sudo bash deploy/install_port_redirect.sh  # nftables port 80 -> 5000
-sudo bash deploy/install_netwatch.sh       # uplink watcher + hotspot profiles
-sudo bash deploy/install_video_tools.sh    # ffmpeg for dashcam thumbnails
-sudo bash deploy/install_watchdog.sh       # 10s hardware watchdog
-sudo bash deploy/install_app_updater.sh    # Android APK mirror timer
-```
-
-The manual order matters: `install_netwatch.sh` expects the `home-wifi` and
-`Hotspot-local` profiles to already exist (create them with `nmcli`, or just let
-`auto_install.sh` do it).
