# 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  `IN PROGRESS` → `SHIPPED` (deployed + verified) or `WONTFIX`/`SUPERSEDED` as appropriate.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**: n/a
- **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**: n/a
- **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**: `IDEA`
- **Area**: Settings page / odometer display (Pi `app_settings`, `/api/stats`, trip odometer)
- **Phase**: n/a
- **Requested**: owner — the 2013 Yaris's ECU is (as expected) NOT exposing OBD PID 0xA6
  odometer (see Phase 24.6), so the odometer reads nothing.
- **Idea**: allow the owner to enter the vehicle's current odometer reading once in the Settings
  page; the app then computes a rolling odometer by adding subsequent trip distances
  (from `trips` table cumulative distance) to that entered baseline, instead of relying on the
  unavailable OBD odometer PID.
- **Outstanding considerations**: what happens when the user's entered value comes from the car's
  instrument cluster vs the OBD one being absent — this would be the *only* odometer source in
  that case; needs a clear "this is a manual baseline" indicator in the UI so it's not mistaken
  for a live OBD reading; decide whether it should also sync to the remote device config
  (Phase 25.5) or stay local.
