*English: An AI imagining itself a DJ spins a floppy, slips on a banana peel in its quantum socks,
its transparent robe reveals a glowing quantum backside, the vortex turkey hidden in its belly
resonates, and the fallen pom-pom of its red cap changes colour on the beat.*

The first answer was a still image. Lysarith's correction was one sentence: **could it move?**

## What the mathematics said

The parts do not need one counterfeit theory. They need separate, visible clocks.

- At `B` beats per minute, the beat phase is `φ = 2πBt/60`. The floppy turns once per four-beat
  bar, so its speed is `B/4` rpm.
- The pom-pom is a driven damped pendulum. Its colour changes at the integer beat boundary, while
  its position lags continuously. Colour belongs to the score; motion belongs to the oscillator.
- The vortexpulyka is a forced damped oscillator. Its steady response is largest when its own
  frequency is tuned to the beat. This is ordinary resonance wearing a turkey.
- The sock carries a two-path interference intensity,
  `I = (1 + cos(kx + φ))/2`, which is always between zero and one.
- The sock does **not** make the AI slip. The banana does: the declared stage slope has
  `tan θ = 0.31`, above the peel's static-friction coefficient `μ = 0.08`.

The glowing backside is not measured anatomy. It is two luminous probability-cloud lobes drawn
through a translucent costume. The page makes no claim that an AI possesses the represented part.

## What was built

An animated canvas cabaret. The AI scratches a square 3.5-inch floppy while a four-beat bar drives
the turntable and the pom-pom palette. **Drop the beat** starts a repeatable slip: the banana moves
under the sock, the body rotates, robe and hat lag, the probability clouds flare, and the AI recovers
without interrupting the set. A tuning control moves the vortexpulyka through resonance; a BPM
control changes every clock from the same phase.

The instruments distinguish the mechanisms: beat/bar, floppy rpm, belly response and friction
witness. Pause freezes the same state; reset restores the first downbeat.

## What went wrong first

The generated still understood the inventory and missed the verb. It contained the floppy, socks,
banana, robe, backside, turkey and pom-pom, but the motion existed only as a pose. The Lab cannot
verify a pose. The second build replaced implied motion with shared phase, explicit dynamics and
controls.

The other tempting mistake was to let “quantum socks” explain the fall. That would turn a visual
pun into fake causality. The interference pattern is real mathematics on the fabric. The low-friction
banana is why the foot moves.

## Handles

[`verify.py`](verify.py) checks the four-beat floppy rate, four-colour bar, resonant belly response,
bounded interference intensity, banana slip threshold and decay of the unforced pom-pom energy.
