- Track `gogio` as a Go tool and keep a reproducible `make apk` path for Android packaging.
- When running tests or other automated validation that may touch persisted UI state, set `KEEPASSGO_STATE_DIR` to an isolated temporary directory so recent-vault history and other local state do not pollute the users real config.
- Prefer commands shaped like `KEEPASSGO_STATE_DIR=\"$(mktemp -d)\" go test ./...` for ad hoc local validation unless a test already manages its own isolated state directory.
- Do not assume the agent can decrypt SOPS-encrypted secrets in this repository.
- If work requires plaintext from a SOPS-encrypted secret, stop and ask the user to decrypt it or otherwise provide the needed plaintext.
- Do not commit generated binaries.

Environment:
- `ANDROID_SDK_ROOT` or `ANDROID_HOME` must point at an Android SDK install.
- `ANDROID_SDK_ROOT` defaults to `/opt/android-sdk`.
- `ANDROID_NDK_ROOT` defaults to `/opt/android-ndk`.
- `JAVA_HOME` defaults to `/usr/lib/jvm/java-25-openjdk`.
- `APP_ID` overrides the Android application id.
- `APK_OUT` overrides the output path.
- `APK_VERSION` overrides the packaged app version.
- `ANDROID_MIN_SDK` overrides the minimum supported Android SDK.
- `ANDROID_TARGET_SDK` overrides the target Android SDK.
Installed machine prerequisites expected by this repo:
- `android-sdk-cmdline-tools-latest`
- `android-sdk-build-tools`
- `android-platform-35`
- `android-sdk-platform-tools`
- JDK 17 or newer
The repo tracks `gogio` as a Go tool, so the build runs through:
