OptionalcwdDirectory for path resolution / default-file discovery; defaults to process.cwd().
OptionalenvBase env for ${VAR} substitution; defaults to process.env. A .env
file next to the stack file fills gaps (base env always wins).
OptionalorganizationInjected into documents missing metadata.organization before validation.
OptionalpackPack remote-build (build.mode: 'remote') compose contexts into content-
addressed tars and pin their digests (Phase 5). Default true; set false for
a dry-run/validate that never ships, so it doesn't tar the project dir.
Options for loadStackFile.
