The three restrictions
Blind can interact with the bomb but cannot use color or readable screen information normally. Mute is the only player who can read the manual but cannot speak. Deaf can see the device and gestures but cannot hear the team. Each restriction determines how information must travel.
Build a handoff chain
Deaf should convert visible state into agreed gestures or text. Mute interprets the manual and communicates through the supported nonverbal channel. Blind repeats the resulting instruction before acting. If the chain breaks, stop and identify the missing fact instead of filling the silence with guesses.
