# yaris-obd Bug Tracker

Standalone bug/issue tracker. One `## BUG-XX` per issue. Numbering sequential.
**Status**: `OPEN` → `IN PROGRESS` → `CLOSED` (with commit ref + verification).
When CLOSED, move the entire entry to Resolved — don't duplicate.

## Resolved

### 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.
