-Reads from a file continuously, similar to 'tail -F', with handling for common log file scenarios.
+Reads from a file continuously with automatic handling of log rotation and truncation.
 
-## Core Features
+### Core Features
 
-- **Log Rotation**: Detects when a file is rotated (renamed/recreated) via inode changes and seamlessly switches to the new file
-- **Truncation**: Detects when a file is truncated and resets to read from the beginning
-- **Position Recovery**: Optionally persists read position to disk for crash recovery

-This component can persist position state to disk via the state_dir option. This differs from Bento's default "no disk persisted state" philosophy but enables resuming from the last position after restarts. If crash recovery is not needed, you may omit state_dir or use a tmpfs mount.

+This component uses fsnotify for file change detection, which has the following constraints:
 
-- **NFS/Network Filesystems**: fsnotify does not work reliably on NFS or other network filesystems
-- **Supported Platforms**: Linux (inotify), macOS (FSEvents), Windows (ReadDirectoryChangesW), BSD variants (kqueue)
-- **Container Environments**: Ensure the file path is mounted from the host, not a container-internal path
+- **NFS/network filesystems**: fsnotify does not work reliably on network-mounted filesystems

+  properly mounted and accessible
 
-## Delivery Semantics
+### Delivery Semantics
 
-- Normal operation: effectively exactly-once (position persisted on message acknowledgment)
-- After crash/restart: at-least-once (may replay messages since last checkpoint)
-- During rotation: position resets to beginning of new file
