◈ GOLD nodes rotate — tap to spin · complete the route and the trace fires automatically
EMITTER — signal source
JUNCTION gold=rotatable, turns GREEN when energized
welded (grey): fixed — powers CYAN, never green
DIODE — one-way (arrow = flow) LOCK — red INPUTS (need all) + green OUTPUT INTRUSION — signal MUST pass; energizing starts a trace timer OBJECTIVE — power every input
DECOY — looks routable, but breaks (SIGNAL LOST)
XOR LOCK — breaches with EXACTLY ONE powered input
GATE — one-way valve; opens when its SWITCHES are on SWITCH — energize to flip; turns GREEN and opens its gate
TUNNEL — portal pair; signal jumps between the linked ends
SEQUENCE — energize the numbered nodes in order
RESISTOR — passable, but adds a score penalty REPEATER — passable and grants a score bonus UPLINK — network objective; routes the signal to the next board DOWNLINK — where the signal re-enters on the next board
LIVE SIGNAL — particles flow to objective
dormant line (connected, unpowered)
