greenlight

The server operates locally via file I/O and standard I/O, primarily writing to and reading from `~/.greenlight/status.json` and `~/.greenlight/display.pid`. It uses `process.kill(pid, 0)` to check for process existence, which is a safe operation. User-provided messages are stored in a local JSON file and then displayed in the terminal. While the application does not execute these messages, there's a theoretical, low-risk possibility of a compromised AI injecting malicious ANSI escape sequences into the message that a vulnerable terminal emulator might misinterpret. However, the risk is contained to the local terminal session, and the application itself does not execute arbitrary code. No hardcoded secrets or direct network risks were identified within the server's code.
