ATLAS / NEON RELAY / SIGNAL PUZZLES
Route the charge.
Four small circuit problems. Configure the relays, test the board, read what actually happened, then recover from the mistakes you created.
Failure Laboratory context: relay behaviour remains a synthetic circuit. Open Failure Laboratory context
Wake the beacon from the upper source bus. The lower feeder is physically isolated.
R1 / A is the clean direct branch to the beacon.
Challenge 01 Ignition. Phase cold. R1 OPEN, R2 OPEN, R3 OPEN, R4 OPEN. Outputs: beacon 0, archive 0, actuator 0. Circuit cold.
Pick a challenge, rotate the available relays, then ENERGISE. The board evaluates the route only from its current deterministic configuration.
Shared traces accept one feed. Unsafe convergence, the ground dump, or a protected output opens the fuse. Fix the route before resetting protection.
Click a relay to cycle OPEN → A → B. Shift + click reverses. Keys 1 to 4 select challenges. R resets exactly.
