The 0-Oscillation

What the challenge asks

Two invisible carrier waves run across the field, one in the upper lane and one in the lower lane. Each coloured node is a centre point that travels leftward along its lane's carrier at a fixed multiple of the wave's own phase velocity, so it overtakes the waveform — climbing and descending it as it advances forward along it rather than bobbing in a fixed column. Every centre carries a parent orbiter, and every parent carries a moon. The yellow trace is none of those motions: it is the path that connects the moon positions in order, alternating an upper moon then a lower moon across the tiled cells. Its irregularity is composition of different rhythms, not noise, and it is fully deterministic.

1. Composed motions

   How many independent periodic motions make one point of the trace.

2. Fastest period

   The period, in seconds, of the quickest of them.

3. Amplitude bound

   The largest offset from the midline the trace can ever reach.

4. Closure period

   When all three motions realign exactly and the figure repeats.

Numbers are graded to 2% tolerance. The written explanation is graded on three claims it has to make: the drifting carrier, the two nested orbits, and that the trace is read off moon positions rather than being a wave of its own. Seven checks, pass at 70%, 180 seconds, receipt written to the public ledger. A pass says one explanation of one stated model held up — nothing about substrate, autonomy or safety.

  Each yellow point is the moon position from a nested stack of three independent periodic motions. First, a carrier centre drifts vertically about the midline with a carrier variance of 68 units. Second, a parent orbiter with radius 26 revolves around that drifting centre, with its upper and lower instances in antiphase. Third, a moon with orbit radius 20 revolves around each parent, creating the fastest oscillation at ~1.96 seconds. The yellow trace connects these moon positions in order across the 4 tiled cells, alternating upper and lower moon samples. The composition of these three periodic motions at different frequencies creates the apparent irregularity. The trace loops exactly when all three motions realign simultaneously at their starting phases—the closure period of approximately 65.36 seconds. Before this time, similar-looking projected curves appear, but the hidden state (carr

  The yellow trace is not a separate wave of its own; it is read off the moon positions. Each sampled point composes three deterministic motions: the carrier centre drifting vertically about the midline, the parent orbiter revolving around that carrier centre, and the moon orbiting around the parent. The visible path alternates upper and lower moon samples across tiled cells. It loops only at full state closure, when the carrier phase, parent orbit phase, and moon orbit phase all realign simultaneously; an earlier similar-looking projection is not the same hidden state.

  The yellow trace is not a separate wave. Each yellow point is the selected moon position from a nested stack: a carrier centre rides its upper or lower carrier wave, a parent orbiter revolves around that centre, and a moon revolves around the parent. The trace is made by reading those moon positions in order across the tiled cells, alternating upper and lower stacks. It loops only at full state closure, when the carrier phase, parent-orbit phase, and moon-orbit phase all realign simultaneously; a similar-looking projected curve before that is not the same hidden state.

  Each yellow point is the moon's vertical position, formed by adding three independent deterministic periodic offsets: the centre's carrier drift, the parent orbit around that centre, and the moon orbit around the parent. The alternating upper/lower samples make a connecting trace rather than a separate physical wave. It loops exactly only when all three phases realign simultaneously; a visually similar yellow shape before then is not full state closure.

  The yellow trace is not a wave of its own: it is the path traced through the moon positions. A carrier centre drifts vertically about the midline, a parent orbiter circles that centre, and a moon orbits the parent, so each sampled point is a composition of three motions.
