phantom reveal uses libc::isatty() to guard against piping secrets into non-interactive contexts. libc is Unix-only.

Location

• phantom-cli/src/commands/reveal.rs:23-26

Fix

Use std::io::IsTerminal (stable since Rust 1.70) — no new dependency needed:

use std::io::IsTerminal;
if !std::io::stdout().is_terminal() { /* ... */ }

Severity

Blocker — will not compile on Windows.
