While developing a chat application storage service, the author employed property-based testing to systematically explore the input space, unexpectedly uncovering a JavaScript prototype handling security vulnerability. This flaw, overlooked by traditional unit testing and manual review, was exposed within just 75 random test iterations. The article details the specification-driven development (SDD) process, how a "round-trip" property was defined to verify the correctness of storing and retrieving API keys, and the vulnerability remediation process. This real-world case highlights the critical value of property testing in AI development: it captures edge cases that human intuition and conventional testing struggle to reach, effectively preventing security risks in production environments. For developers relying on AI (such as LLM-generated code), this provides a practical guide to automated testing, emphasizing that security testing must go beyond "happy paths" to cover extreme scenarios like malicious inputs.

The UK has recently introduced a legislative amendment seeking to prohibit children under 16 from using mainstream online services, including instant messaging, family photo sharing, Wikipedia, and more. The amendment requires all 'regulated user-to-user services' to implement 'highly effective age verification,' with an extremely broad scope that even covers self-hosted services. The article points out that this would require ordinary users to provide identification to numerous websites, raising serious privacy concerns. Additionally, this regulation would impose a disproportionate burden on small service providers, potentially leading to malicious compliance. The author believes the amendment is overly broad and severely mismatched with the 'social media problems' it aims to solve. The proposal reflects the potential far-reaching impacts of the UK's Online Safety Act 2023 in practical implementation and warrants attention from the tech industry.
