+## CI and workflows
+
+GitHub Actions on **`main`** / **`master`** run **[`.github/workflows/ci.yml`](.github/workflows/ci.yml)** (Linux containers, macOS, Windows, Android, optional log checks). The **Android** job uses **JDK 21** in CI, and the vendored **JoyStick** library uses the same **Gradle 8.13** wrapper as the root app so Gradle can instrument current dependency bytecode (for example BouncyCastle multi-release JARs). **[`build.yml`](.github/workflows/build.yml)** (ETLBuild) runs on tagged releases, a weekly schedule, and manual dispatch. **[`snapcraft.yml`](.github/workflows/snapcraft.yml)** builds the upstream **[etlegacy-snap](https://github.com/etlegacy/etlegacy-snap)** tree after ETLBuild completes; it expects **`SNAPCRAFT_STORE_CREDENTIALS`** where publishing is desired.
+
+Forks without **`LEGACY_CI_WEBHOOK`** still get a full CI signal; the optional Discord notify step is skipped when that secret is unset. The **`check-compiler-warnings`** job scans native build logs for new compiler warnings in game code; **Android** and **Windows** (`win` / `win64`) logs are treated as informational only (see `misc/collect-and-check-gh-build-logs.py`).
