Install Ghidra 12.2 from the official GitHub release into /opt/ghidra, verified against the SHA-256 in the release notes, with Ubuntu's openjdk-25-jdk (Ghidra 12.2 requires Java 25). Version, build date and hash are build args. The entrypoint, renamed from launch-claude.sh to launch-apps.sh, now starts both apps and stops both, ending the container, when either is closed: Ghidra when its process exits (closing the project window), Claude Desktop when none of its windows is open or minimized. Claude is stopped via its main process so it can shut down its own helpers. CLAUDE.md now records that Claude Desktop and Ghidra share one container, at the user's request.

# Container entrypoint: start Claude Desktop and Ghidra, and stop both (so the
|
|
# container exits) as soon as either one is closed.

# - Ghidra exits when its project window is closed, so its process ending is
|
|
# the signal. Closing other Ghidra windows (CodeBrowser, Help) doesn't count.
|
|
# - Closing Claude Desktop's window only hides the app (it keeps running for
|
|
# the tray icon, which GNOME doesn't show). So its X windows are watched and
|
|
# it counts as closed once none of them is open or minimized.
