# Codon/DNA-RNA-Protein Translator implementation

A source-bound implementation contract for Codon/DNA-RNA-Protein Translator; deployment and executable qualification remain separate.

Status: **VERIFIED_CLEAN**Lifecycle: **implementation-contract**

## Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

**Record owner**: Guth Instruments

**Lifecycle**: verified-clean

**Evidence ID**: t7-087

**Effect**: Computation or source lookup only

## Input and validation requirements

The specification provides no stated resource limit or rejection behavior for extreme-length inputs, so a naive lookup implementation can fail through allocation or indexing exhaustion. It also leaves DNA strand orientation ambiguous, allowing the same written sequence to translate as different amino-acid sequences.

## Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

## Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.
