Buildpack Specification

The Buildpack API (currently 0.12) defines the contract between an individual buildpack and the lifecycle. It specifies the on-disk layout of a buildpack (buildpack.toml, bin/detect, bin/build), the build plan provides/requires graph, layer types (launch/build/cache), launch.toml and build.toml outputs, target declarations (os/arch/distros), SBOM emission, and the CNB_* environment variable contract.
