What problem does it solve? Developers working on the Zeus Lightning wallet often struggle with knowing when to restart Metro versus rebuilding the native app, connecting the app to a Lightning node in development, and navigating the Android reproducible release process. This Skill provides a verified runbook covering all of these operational tasks. ## Core Features & Use Cases - Dev Run Guidance: Start Metro, Android, and iOS builds with the correct yarn commands, and use a decision table to determine whether a change requires a Metro restart or a full native rebuild. - Node Connection Setup: Configure any of the 7 supported backend implementations (LDK Node, Embedded LND, LND REST, LNC, CLNRest, NWC, LNDHub), including the critical Android emulator 10.0.2.2 host rule and Polar-based local dev networks. - Release Operations: Execute the Docker-based reproducible Android build via ./build.sh, verify release APK hashes, understand per-ABI versionCodes, PGP-signed commits, and the "Version bump:" commit convention. - Use Case: You changed a native dependency and the app does not reflect your change — consult the restart-vs-rebuild decision table to learn that native changes require a full rebuild, not a Metro restart. ## Quick Start Ask how to run the Zeus app in development and connect it to a local Polar Lightning node from the Android emulator.
