Inputs for render_app_yaml. All fields are pre-resolved by the caller.

Fields

name: String

Sanitized DO app name (output of sanitize_do_app_name).

repo: String

owner/repo for github.repo, or fallback placeholder.

web_bin: String

The bin matching the package name — kept for symmetry, not currently emitted (the web service is hardcoded in the template).

workers: Vec<String>

Non-web, non-test-like bins to emit as workers.

env_lines: Option<Vec<EnvLine>>

Structured .env.example lines (keys + blank separators). None when .env.example is missing — the renderer emits an empty envs block and the caller logs a warning (D-06 graceful missing-file path).

preserved_name: Option<String>

Identity override: DO App Platform app name from an existing file. When Some, takes precedence over name (derived from package name).

preserved_region: Option<String>

Identity override: DO region slug from an existing file. When Some, takes precedence over the default (fra1).

preserved_github_repo: Option<String>

Identity override: github.repo from an existing file. When Some, takes precedence over the git-remote-derived repo.

preserved_github_branch: Option<String>

Identity override: github.branch from an existing file. When Some, takes precedence over the default (main).
