# API Contract

The frontend calls Tauri commands with `@tauri-apps/api/core.invoke`.

## Shared payloads

```ts
type FileStatusKind = "modified" | "added" | "deleted" | "renamed" | "untracked" | "conflicted" | "unknown";

interface GitStatus {
  repo_path: string;
  current_branch: string | null;
  upstream: string | null;
  ahead: number;
  behind: number;
  files: GitFileStatus[];
  clean: boolean;
}

interface GitFileStatus {
  path: string;
  old_path: string | null;
  staged: FileStatusKind | null;
  unstaged: FileStatusKind | null;
}

interface GitBranch {
  name: string;
  current: boolean;
  remote: boolean;
}

interface GitCommit {
  hash: string;
  short_hash: string;
  summary: string;
  author_name: string;
  author_email: string;
  date: string;
  refs: string[];
  files: GitCommitFile[];
}

interface GitCommitFile {
  path: string;
  old_path: string | null;
  status: FileStatusKind;
}

interface GitRepositoryFile {
  path: string;
  tracked: boolean;
  status: FileStatusKind | null;
}
```
