TERM_PROGRAM env variable
$TERM_PROGRAMThe
TERM_PROGRAM environment variable identifies the specific terminal emulator running the session, independent of the more generic TERM value. Common values include iTerm.app, Apple_Terminal, WezTerm, vscode, ghostty, and Hyper.
A companion variable, TERM_PROGRAM_VERSION, reports the emulator's version string and lets applications gate features on minimum versions. The pair was popularized by Apple Terminal and iTerm2 and is now widely set by macOS-friendly terminals as well as several cross-platform emulators.How this is testedmanual
Manual verification required — no automated probe available.

The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
