 **Reduce edge cases and unexpected behavior.** Design for the common path. When edge cases arise, validate assumptions early and fail fast rather than adding complex branching logic.

+**Scripts fail on error.** Shell scripts use different strictness levels depending on context:
+- Sourced scripts (lib.sh, core.sh, setup.sh): `set -e` (no `-u` due to Node.js package compatibility issues with unset variables)
+- User-facing CLIs (android.sh, ios.sh, devices.sh): `set -eu`

 **Validation warns but doesn't block.** User-facing validation commands (like lock file checksum mismatches) should warn with actionable fix commands but never prevent the user from continuing. The validation philosophy is "inform, don't obstruct."

 ## Configuration
 
-Configuration for both Android and iOS plugins is now managed via environment variables defined in `plugin.json`. These env vars are converted to JSON at runtime for internal use.
