The Matrix runs from code, and the code runs from a seed. One number emanates an entire world, exactly and repeatably — the same seed always the same world. Change it by a single bit and a wholly different world falls out. The One determines the many, and determines them completely.
A real xorshift32 PRNG seeded by the shown integer generates the field of glyphs — the 'world'. Press same seed again and the world is byte-for-byte identical (its hash unchanged): deterministic emanation, verifiable. Press flip one bit and a single-bit change to the seed produces a world differing in most cells — the avalanche, measured live as the Hamming fraction. (For the A=10 glyph alphabet, two independent worlds disagree in ≈ 1 − 1/A ≈ 90% of cells, which the readout confirms — full sensitivity, not the ~50% you'd see over a binary alphabet.) Determinism and sensitivity, both real.
'Worlds from a seed', 'the Matrix runs from code' — the figure. The object is a pseudo-random generator: deterministic given its seed, statistically scrambled under small changes. No claim a universe is literally a PRNG stream; the point is that a tiny source can fix an entire structure.
