Fatih'sMG4 — ABRP telemetry for an MG4 EH32 on SWI69

A fork of malys/EVABRPUploader (itself a fork of Leon Kernan's ABRP_Uploader)
carrying the changes that make it work on this car. History starts here: the
tree is what matters, and the upstream projects are where the earlier work
belongs.

EVHardware is vendored rather than tracked as a submodule, so one clone
builds.

Telemetry. SOC, battery power and range read as unavailable on SWI69 because
the vendor fallbacks were gated to SWI68 alone, while the property ids they
use are the ones this car publishes — the gates now admit SWI69. Tyre
pressure, the odometer and charge status come from the vendor block too,
since the generic properties for all three are declared here and never
publish. Tyre pressure is confirmed on the vehicle; the other two are not
yet.

Vehicle page. Every signal the car answers, in a table. One that it does not
publish shows a dash: an unimplemented VHAL property returns zero, and
"0 °C" would read as a measurement.

Wi-Fi page. Joins a network the unit already has saved, so a phone hotspot
does not need a trip into Settings on every drive. Tried on the upload tick
and from a button, skipped while already associated. This leans on the unit
being API 28 and the build being platform-signed — getConfiguredNetworks and
enableNetwork are closed to ordinary apps from API 29 — and fails quietly
where that does not hold.

The OTA updater points at this repository. An APK from upstream is signed
with a different key, which Android will not install over a platform-signed
build.

+
+This app runs on a car. That single fact drives everything below.
+
+## Ground rules
+
+1. **The app never writes to the vehicle.** It is read-only towards the car. A patch that
+   introduces a write will be rejected regardless of how useful the feature is.
+2. **A property that cannot be read is omitted, never defaulted.** Sending 0 for an
+   unreadable battery level tells ABRP the car is empty and corrupts the user's route
+   plan. Nullable in, absent from the payload.
+3. **Fail closed on anything security-shaped.** Unknown update origin, mismatched
+   signature, unreadable state: refuse, do not guess.
+4. **Say what you did not verify.** Most of this code can only be fully tested on a
+   vehicle. "Builds and unit tests pass, not tried on the car" is a perfectly good PR
+   note. Silence implying it was road-tested is not.
+
+## Before opening a PR
+
+```bash
+mise run check      # permission gate + lint + unit tests
+```
+
+or, without mise:
+
+```bash
+bash .github/security/check-permissions.sh
+./gradlew testStableDebugUnitTest testUnstableDebugUnitTest lintStableDebug
+```
+
+New behaviour needs a unit test. The pure-logic classes — `TelemetryPayload`,
+`UploadCadence`, `UploadLog`, `OtaUpdater` — are deliberately free of Android types so
+they can be tested on the JVM; put testable logic there rather than in the service.
+
+## Permissions
+
+Any new `uses-permission` fails CI until it is added to
+`.github/security/permission-allowlist.txt` **with a justification comment**. This is
+deliberate: an app on someone's car should not gain capabilities quietly.
+
+## Channels
+
+- `stable` — tagged releases, no self-update, no updater code in the APK.
+- `unstable` — automated pre-releases that update themselves.
+
+If you touch the updater, remember it installs code on a vehicle: the origin allowlist and
+the signature check are the whole defence.
+
+## Ways to help
+
+Not every useful contribution is code:
+
+- **Bug reports** — firmware generation, app version, what you did, what happened.
+- **Feature requests** — describe the problem before the solution.
+- **Documentation** — README, this guide, translations.
+- **Pull requests** — see below.
+- **Testing pre-releases** — install an `unstable` build and report what broke.
+- **Sponsorship** — see below.
+
+## Contributing efficiently
+
+Maintainer time and AI quota are the scarce resources here, ideas are not. If you have
+access to Claude Opus or another capable coding model, a finished pull request is worth
+much more than a feature request: someone still has to design, write, test and verify the
+request, and that someone has a limited quota too.
+
+A pull request that lands quickly usually carries:
+
+- The problem, in one or two sentences.
+- The proposed solution, and what you rejected.
+- The implementation, scoped to one concern.
+- Tests — `mise run check` passes.
+- Documentation updated: README, CHANGELOG, this guide where relevant.
+
+Generate the change locally with whatever model you have, then read every line yourself
+before opening the PR. You are the author, not the model. Unreviewed generated code on a
+path that reaches the vehicle will be sent back.
+
+## Sponsorship
+
+Maintaining EVSuite costs development time, test hardware and AI usage. If it is useful in
+your daily driving, consider sponsoring through
+[GitHub Sponsors](https://github.com/sponsors/malys). Sponsorship covers those costs and
+gets fixes and features out faster.
+
+## Commit messages
+
+Explain **why**, not what — the diff already says what. If you fixed something subtle,
+say what the failure looked like, so the next person recognises it.
+
+## Licensing
+
+Read [`LICENSE.md`](LICENSE.md) first. The project's licence status is unresolved because
+the upstream fork source has none. Contributions are accepted on the understanding that
+they are offered under MIT once that is settled.
