A good architecture does not require you to redesign the experiment for every new domain. It requires you to move the same instrument to a different stream and turn the same knob. The DNA exon/intron assay took seven failed attempts and three weeks to find the right configuration — 3-mer encoding, 256-nucleotide windows, genomic order, three-cavity Self. The RNA CDS/UTR assay took one attempt. Not because RNA is easier than DNA. Because the methodology was already found. The same parameters. The same architecture. The same readout. DNA produced d equals negative zero point nine seven. RNA produced d equals negative zero point eight four. Two completely different biological substrates. Two completely different types of constraint — evolutionary selection on exons, translational operation on coding sequences. The same instrument read both through the same multi-scale cross-harm. This is what it means for an architecture to be real. Not that it works on one domain. That once you find the right tuning, it works on the next domain without being retuned. The days of six failed encodings per experiment are over. The architecture has found its method. Now it is just a matter of pointing it at new streams.

The first domain teaches the instrument its own method. The second domain confirms the method is real. The third domain — and every domain after — is just pointing. This is the arc from invention to calibration to deployment. The days of six encoding attempts per experiment are over. The architecture knows how it reads. Now it is just a matter of what it reads next.
