    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.

    files exchanged on disk (group.toml, plan.toml, order.toml, run.toml, metadata.toml, report.toml,

    The Distribution API (currently 0.3) defines how buildpacks, extensions, and builders are packaged
    as OCI artifacts and published to OCI registries. Covers labels (io.buildpacks.buildpack.api, io.buildpacks.buildpack.layers),
    multi-buildpack OCI artifacts, and image extension distribution.

    Image extensions emit Dockerfile snippets applied by the `extender` lifecycle binary to the build
    and/or run image. Share the buildpack surface (extension.toml, bin/detect, bin/generate) but produce
    Dockerfile output instead of layers — enabling base-image customization (apt packages, native libs)
    inside a buildpacks workflow.

description: >-
  Cloud Native Buildpacks (CNB) is a CNCF Graduated project (graduated 2026-07-17) that transforms application source code into OCI images
  that can run on any cloud. The v3 specification — Buildpack API 0.12, Platform API 0.15, and Distribution API 0.3 —
  defines a modular, vendor-neutral contract between buildpacks, builders, lifecycles, and platforms. CNB consolidates a
  decade of production experience from Heroku and Pivotal/Cloud Foundry and provides the reference lifecycle
  (buildpacksio/lifecycle), the `pack` CLI, language bindings (libcnb in Go/Rust/.NET), the Kubernetes-native `kpack`
  platform, the public community registry at registry.buildpacks.io, and an open RFC-driven governance model.
