STEP 1: BREAK NOTICE — THE GREAT RELEASE
The structure bends. Plates slide. A sharp tone races through hidden ducts. Tiny dark units burst from seams. They sense tilt by reading strain-maps using the rule:
strain = delta_length / original_length
If strain greater than 0.07, release = 1.
To a tiny mind: “When the room stretches too much, the little dots wake up.”

STEP 2: NET FORMATION — THE QUICK GRIP
All units lock to each other using pulse-mag bonds. Each unit fires field strength F = k * q1 * q2 / r^2.
They self-align into hex-layers. Think: “Dots hold hands fast to make a strong sheet.”
The sheet shoots under the falling roof and catches it.

STEP 3: SOFT HOLD — THE GENTLE STOP
The roof pushes downward. The hex-sheet spreads the push evenly. Load spreads by:
pressure = force / area
The sheet keeps growing area so pressure stays tiny.
Simple mind picture: “More dots join so no one feels a hard poke.”

STEP 4: SHIFT-SKIN — THE AUTO-THICKENER
Aftershock hits. Pressure spikes. Units sense push using:
stress = modulus * strain
If stress rises, nearby units triple-stack.
stack_count = base_count * (1 + stress_ratio)
Meaning: “Where it hurts more, the dots make the sheet thicker.”

STEP 5: COUNTER-TILT — THE BALANCE MAKER
The whole structure leans sideways. The net tilts too, but flips its lower edge downward. It uses tiny thrusters giving upward lift L such that:
L = mass * gravity * tilt_ratio
This keeps everyone level.
Simple: “Dots push up so the floor stays flat like calm water.”

STEP 6: GAP FILL — THE HOLE BLOCKER
Cracks open. Units dive in, forming plugs shaped by:
volume_target = length * width * depth
They match the hole shape and harden.
Idea: “Dots fill empty space so no one falls.”

STEP 7: PATH BUILD — THE SAFE LINE
The net slowly unwraps itself, turning into a glowing trail. Units with glow-cores stay at the top, others clear rubble. Debris lift uses:
lift_force = thrust_output − weight_piece
If lift_force higher than 0, debris moves.
Simple: “Dots clear stones and show where to walk.”

STEP 8: EXIT RAMP — THE BRIDGE MAKER
A steep pile appears. Units stack into a slope shaped by:
slope_angle = arctan(height / length)
They pick angle less than 15 degrees so steps feel easy.
Simple: “Dots make a smooth hill so feet can go down safe.”

STEP 9: COMPLETE RETREAT — THE VANISH FINISH
When all are out, the units snap apart and stream back into vents. System resets.
Simple: “Dots go home after helping.”
