Inspectable code / Software simulation

DNA/RNA-inspired simulation, corrected.

A standalone Python example for reversible string encoding, sequence lookup, and virtual-node state. It has no RF, medical, genetic-engineering, or body-sensor capabilities.

What this code does

It encodes each byte as four A/C/G/T characters, decodes those strings, and checks stored payloads against a hash and length. It normalizes sequence text, looks up codons from a fixed reading frame, and stops at the first stop codon. Virtual nodes are immutable snapshots backed by in-memory state; activation, silencing, and sensitivity changes affect only that software state.

What changed from the supplied prototype

• Invalid data is rejected. Unknown bases no longer silently become zero bits; incomplete byte encodings and incomplete codons fail explicitly. Sequence and payload lengths are bounded.
• Sequence handling is consistent. Lowercase is normalized before processing and hashing. Translation stops instead of continuing after a stop codon. Anticodon input has an explicit 3′-to-5′ orientation and is complemented to a codon; this simplified lookup does not model wobble pairing.
• False frequency claims are removed. The duplicate codon-offset entry and conflicting MHz/GHz arithmetic are replaced by a unitless symbol score. Different sequences can share that score. A full SHA3-256 hash is an integrity label, not a biological identity or proof of authenticity.
• State changes are inspectable. Unknown nodes, duplicate IDs, unsupported operations, and invalid sensitivity values raise errors. A returned status reflects an actual in-memory change rather than a hard-coded programming-success claim.
• No special dependencies. The corrected version uses typed standard-library Python, ASCII console output, and a short JSON demonstration instead of an unverified biological-success report.

Open it in your editor

Save the download as dna_node_simulation.py and open it in VS Code. From the folder containing the file, run:

python dna_node_simulation.py

No package installation, account, API key, or internet connection is needed to run the downloaded demonstration. It uses synthetic example strings. Do not replace them with personal genetic or biosignal data for public sharing.

The code uses Python 3.10+ syntax and was tested on Windows with Python 3.12.10. Other runtimes and platforms have not been verified. State is not saved between runs; storing again replaces that virtual node's previous payload. Silencing is a flag until explicitly cleared, not a timed biological effect.

Scope and compatibility

This is a corrected, software-only adaptation, not a drop-in replacement for the original API. Misleading biological operations were replaced with SequenceMapper, DNADataStorage, and VirtualNodeInterface. It does not design CRISPR guides, produce proteins, alter gene expression, stimulate tissue, or connect to a chain, AI service, sensor, or implant. The original supplied attachment remains unchanged and is not published here.
