Removing one of the 3 AI-virus-protected files now starts a 60-second
window (tracked session-wide via LockedFilesRemovalDeadline). If the
other locked files aren't also removed before it expires, the virus
restores whichever ones were deleted and broadcasts a red warning to
the whole session, forcing players to coordinate the removal instead
of picking them off one at a time.
Also extends the Mercure broadcast payload with an optional 3rd
"messageType" element so pushed messages can render red (virus) or
green (mainframe) instead of always defaulting to green.
Message font dropped from 20px to 14px and the 10px inline margin-bottom
(set from JS on every message) replaced with a 2px CSS margin so the
terminal reads like dense console output instead of spaced-out chat
bubbles. Colors are unchanged.
Connects the previously-disconnected /decode command to per-player
messages: player 1 unlocks sudo for everyone, player 2 unlocks a scan
command that reveals which files the AI virus has locked, player 3
learns those files should be removed.
Also adds a retaliation mechanic: successfully removing a file locks
the player's terminal. The AI virus locks it out in red immediately;
the mainframe reveals a 12-character recovery code in green after 30
seconds, which can be submitted via /unlock to restore access early,
otherwise the terminal auto-recovers after 45 seconds.
