OPEN TERMINATION — signal escapes into air — low headspace pressure — output: dispersed, ambient, lost
rigid sealed vessel — signal trapped, forced into solution — output: standing waves, crystalline, locked
The tube length is identical at every column. The yeast vigor is identical at every row. The same function runs at every pixel.
What changes: only the boundary parameter. Open end or sealed end. Low pressure or high pressure. The process does not determine the output. The edge does.
This was rendered in one pass. No pixel was revisited. The maker could not know the form until it was already committed.
