GC content distribution
Model contract. The engine encodes, adds Reed-Solomon parity, applies 10 independent reads, builds consensus, and performs combined error-and-erasure recovery. Sequencing profiles pair with Twist synthesis so their error models are not applied twice. The raw Fountain profile stays available for short text and reports every biological constraint flag instead of hiding rejected output.

Follow real strands through codec output, modeled molecular noise, consensus, and Reed-Solomon recovery.
