  "description": "Staging area for CANDIDATE version sets awaiting canary certification. `scripts/promote-set.mjs` applies one candidate to a fresh full-featured scaffold (catalog + gradle.properties + wrapper + composeApp/build.gradle.kts compileSdk/targetSdk), builds it for real (Android assembleDebug + the device-free lane gates + the iOS framework link), and ONLY on all-green promotes it into registry.json as a new proven-green set (the new default `upgrade` target). Red leaves registry.json untouched. Same shape as a registry set: `versions` mirrors the [versions] table, `androidSdk` pins compileSdk/targetSdk, plus `status: candidate` and `baseline`.",
