The Harmonics

1. Harmonic h comes at (1 − 3/h) of the life, counted from the big bang (the Data Harmonics law, Part 2.7): Harmonic 4 at a quarter of the life after it, Harmonic 6 at half, and so on, crowding toward the end.
2. Harmonics that fall within one Tempo of each other arrive together, the Tempo being the universe's finest tick.
3. Each harmonic collapses the densest places it finds into new wells, and the lattice rings stronger. Harmonic 4 completes the fourfold scaffold, spacetime.
4. A universe has 3 · 2^L harmonics in its life (the Layer Count Law); past Harmonic 4 they pass quietly, without a banner.

The method, in plain steps:

each step of the life:
    t ← the universe's Tempos since its Data Nova
    while the next harmonic's Tempo ≤ t → advance to it
    if a harmonic was reached → its nova
harmonicTempo(h) = ⌈2^L / 3⌉ + ⌈2^L · (1 − 3/h)⌉     for h > 3

The code:

// public/game-v8.4/app.js:4321 harmonicTempo()
function harmonicTempo(h) {
    if (!uni) return Infinity;
    if (h <= 3) return Math.ceil(uni.rupturePulses * (1 - 2 / Math.max(2, h)));   /* the data's count, beyond time */
    return physicalTempo() + Math.ceil(uni.rupturePulses * (1 - 3 / h));
}

// public/game-v8.4/app.js:4518 updateCore(), the check
const t = universePulses(); let h = novaCount + 1;
if (harmonicTempo(h) <= t && t !== lastHarmonicTempo) {
    while (h < uni.layers && harmonicTempo(h + 1) <= t) h++;
    novaCount = h - 1; lastHarmonicTempo = t; triggerInfoNova();
}
