ADR 0001: Native Android local-first app

Decision

Build v1 as a native Kotlin Android app using Jetpack Compose, Room, and direct UDP NTP probes.

Rationale

• The app needs low-friction device-side network diagnostics.
• No backend is required for saved servers, profiles, local history, comparison, or export.
• Local-only storage avoids telemetry and customer data exposure.

Consequences

• APKs can be built locally or in Gitea Actions.
• Gitea runners must have Android build tooling or install it during the workflow.
• Release builds require signing keys managed through secrets, not committed files.
