# Internal package inventory Public facades and their contracts are defined in Go declarations and GoDoc. The [runtime consumer guide](../consumers/runtime-version.md) covers application usage, and the [CLI contract](../cli.md) covers command behavior. Implemented internal packages: - `internal/runtimeinfo` holds the injected version value and selects the executable's main-module version when no injected value is present. - `internal/versioncontract` names the linker symbol shared with the future release builder. - `internal/apicheck` checks compiled exports with `go/types` and checks import direction. Run it with `go run ./internal/apicheck` from the repository root. - `internal/process` runs cancellable child commands with per-child environment overlays. - `cmd/releasekit/internal/cli` parses implemented commands, loads strict JSON profiles, and adapts configured checks to the process runner. The executable controller uses the runtime facade and the command-owned CLI adapter. The adapter uses the process runner and imports neither public facade. Release orchestration, build, Git, and Gitea implementation packages are introduced as their responsibilities are implemented.
