Android / KMP baseline

House defaults — apply them without reminders or re-derivation; where the project's actual conventions differ, follow the project:

• DI: Hilt + KSP (or android-skills:koin when the project uses Koin). Async: Coroutines/Flow — no LiveData in new code. JSON: kotlinx.serialization. Images: Coil.
• Network/local: Android uses Retrofit/OkHttp + Room; KMP shared uses Ktor + Room or SQLDelight. Retrofit is Android-only — never in a shared module.
• Modules: feature-vertical packages and modules; :core:model has zero Android deps; :feature:* modules never depend on each other.
• Errors: mapped to a domain type at the repository boundary — platform exceptions never leak past it; UI state explicitly models loading / success / error (see android-skills:android-data-layer).

Skill routing

Load the specific skill for the task, always with the fully-qualified android-skills: prefix — never the short name (compose, koin, …).
