Semi is a lightweight, deterrent-focused testing environment designed for environments where system-level kiosk mode is inaccessible or restricted. It isolates a single testing tab into a dedicated, fullscreen popup window while programmatically terminating all other active browser distractions.
While it operates within the standard user-space (avoiding the instability of Incognito mode on managed devices), it provides a robust defense against common integrity breaches by disabling the context menu, blocking clipboard actions (Copy/Paste/Cut), and intercepting navigation shortcuts. It serves as a high-friction deterrent that creates a focused, single-purpose testing shell.
What it does:
Isolates: Closes all other tabs and windows to ensure the student is only on the assigned test.
Focuses: Launches the test in a fullscreen 'Popup' mode, removing the address bar and bookmarks.
Defends: Hard-blocks Right-Click and Ctrl+C/V to prevent the external sharing of test content.
