A PAST INPUT. A CHANGED MATERIAL. A DIFFERENT ANSWER.

Read the wake.

An experience grows crystal. Withdraw the input. Send a pulse.
The material remembers through what it does to the signal.

INVERTED RECEIVER SPACE

ReceiverTime window

The moon resamples the outer wave. Its receivers measure the signal that arrived.

CLOSEST TRAINED FAMILY

Listening…

Readout uses four pulses, four receivers and six time windows. Scores are not probabilities.

Teaching fixture: arc. Hidden from the reader.

WHICH CHANGE WOULD TOUCH THIS ANSWER?

Follow the sensitivity.

The Jacobian colors places where a small material change would raise or lower the selected receiver reading.

THE RECEIPT · 32 HELD-OUT EPISODES

A mechanism you can challenge.

Four known shape families, new noise and geometric variants. All writing input removed for 6,000 steps before reading.

The wave reader matches the direct baseline here. This is a small geometric-memory experiment; semantic recall and a benefit from inversion remain unproven. Inspect the full receipt ↗
