## 1st line of defense: filesystem (Mountain Duck)
## Filesystem Mapping

### macOS NFS POSIX

| folder | file | NFS (POSIX) | affected local operations | implementation (`NfsFileSystemDelegate.getattr`) |
| folder | file | NFS (POSIX) | affected local operations | implementation |
|--------|------|-------------|--------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------|
| | x | `r` | read | `r` <-- `Read.preflight` <-- `readpermission` |
| | x | `x` | exec | `x` <-- TRUE |
| x | | `rx` | ls | `rx` <-- `Read.preflight` <-- `readpermission` |
| | x | `w` | write, rm, mv source file, mv target file (if exists) | `w` <-- (`Write.preflight` OR `Delete.preflight` <-- (`writepermission` OR `deletepermission`) |
| x | | `w` | rmdir, mkdir, mv source folder, mv target folder (if exists) | `w` <-- (`Write.preflight` OR `Delete.preflight` OR `Directory.preflight`) <-- (`writepermission` OR `deletepermission` OR `createdirectoriespermission`) |

N.B. we use `Read` feature for `readpermission` on directories, as well.
N.B. `x` on files is only set for POSIX backends, i.e. never for CTERA.

### macOS File Provider Capabilities

| folder | file | File Provider capabilities (`DefaultFileProviderItemConverter.toFileProviderItem`) | affected local operations |

| x | x | `NSFileProviderFileSystemUserReadable` <-- TRUE | read, ls |

| | x | `NSFileProviderFileSystemUserExecutable` <-- `permission.isExecutable` <-- FALSE for CTERA | exec |

(§) with random file/directory name
(§) with empty file/directory name

N.B. File Provider sets the `x` flag on all folders independent of `NSFileProviderFileSystemUserExecutable`.

### Windows ACLs

| folder | file | access right | affected local operations | implementation (`WindowsAcl.Translate`) |
|--------|------|---------------------|---------------------------------------------------------------------|---------------------------------------------------------|
| | x | `Read` | read, exec | `Read.preflight` <-- `readpermission` |
| x | | `ReadAndExecute` | ls | `ListService.preflight` <-- `readpermission` |
| x | x | `Write` | write, touch, mkdir, mv source file, mv target file (if exists) | `Write.preflight` <-- `writepermission` |
| x | x | `Delete` | rm, rmdir, mv source file/folder, mv target file/folder (if exists) | `Delete.preflight` <-- `deletepermission` |
| x | | `CreateDirectories` | mkdir, mv target folder (if target folder does not exist) | `Directory.preflight` <-- `createdirectoriespermission` |

N.B. `Write` on folders implies `CreateFiles` (=`WriteData` on files) and `CreateDirectories` (=`AppendData` on files).
N.B. `x` on files is only set for POSIX backends, i.e. never for CTERA.
