A five-year design decision to use unsigned integers for sizes in the C3 programming language has created subtle but serious bugs that compound across codebases, with implications extending to any system requiring type decisions for sizes and lengths. The article demonstrates how prioritizing unsigned types creates friction points—implicit conversions, ambiguous promotion rules, and logic errors in common patterns like modulo arithmetic—that undermine code safety despite appearing to work correctly in most cases. For IT organizations, this reflects a broader principle: seemingly minor technical decisions about type systems and implicit conversions can create cascading maintenance costs and security risks that justify rethinking foundational assumptions, even after years of apparent stability.
