| `stat(target, signal?)` | Return `FsInfo` metadata (`version`, `type`, optional `size`), or `undefined` when the target is absent. Never content. |
|
||||
| `lstat(path, opts?, signal?)` | Return `FsPathInfo` metadata without following the final path component when it is a symlink. This is path-shaped so consumers can reject repository-owned symlinks before `resolve` follows them into a target. |
|
||||
| `readText(target, signal?)` | Read the whole regular text file as one decoded string. Owns regular-file checks, UTF-8 decoding, binary/NUL rejection (`FS_NOT_TEXT`). |
