Clean code is not prettiness - it is the structure that lets a competent human understand the problem. In the AI era, it is the steering wheel.https://mavai.org/news/2026-06-24-feotest-medical-showcase/Wed, 24 Jun 2026 00:00:00 +0000https://mavai.org/news/2026-06-24-feotest-medical-showcase/A diagnostic device’s output is stochastic: the same specimen can yield different outcomes — from the biological sample, the reagent chemistry, the electronics, or a firmware change. Conventional pass/fail testing misses this. An open-source, Rust-native framework, feotest makes device performance testable and monitorable: establish a statistically defined baseline, then continuously verify functional and temporal conformance with confidence intervals and auditable verdicts. A runnable medical-device example shows the whole loop, against the 2026 QMSR and EUDAMED evidence environment.https://mavai.org/signals/2026-06-15-the-limits-of-testing/Mon, 15 Jun 2026 00:00:00 +0000https://mavai.org/signals/2026-06-15-the-limits-of-testing/Testing can never feasibly deliver failure rate statistics that an international standard like ISO 262262 demands. This article explains why, why it is still necessary, and why collecting data must not end in the lab.https://mavai.org/news/2026-06-08-introducing-feotest/Mon, 08 Jun 2026 00:00:00 +0000https://mavai.org/news/2026-06-08-introducing-feotest/Probabilistic testing, native to Rust. A non-deterministic service is treated as a stochastic service: establish a statistical baseline, then verify the service still meets it — with confidence intervals, latency distributions, and auditable verdicts.https://mavai.org/news/2026-06-01-javai-is-now-mavai/Mon, 01 Jun 2026 00:00:00 +0000https://mavai.org/news/2026-06-01-javai-is-now-mavai/The frameworks, the websites, the GitHub org and the Maven coordinates have all moved from javai to mavai. Nothing breaks: old URLs 301-redirect, GitHub repo transfers forward automatically, and the final javai Maven artifacts carry relocation POMs. Here is what changed and what, if anything, you need to do.https://mavai.org/news/2026-05-12-punit-0.7.0-alpha6/Tue, 12 May 2026 00:00:00 +0000https://mavai.org/news/2026-05-12-punit-0.7.0-alpha6/The thing a punit author implements gets a more honest name. UseCase carried too many readings — UML, regulatory, generic product talk — and told an author nothing about what the artefact does in the probabilistic-testing context. ServiceContract names it for what it is.https://mavai.org/news/2026-05-07-punit-0.7.0-alpha/Thu, 07 May 2026 00:00:00 +0000https://mavai.org/news/2026-05-07-punit-0.7.0-alpha/First cut of a new authoring surface for punit. Test configuration moves from parameterised annotations into typed builder calls inside the test method body. Statistical early termination and the wider feasibility-gate audit are deferred from this alpha.https://mavai.org/signals/2026-05-06-shewhart-toyota-and-the-probabilistic-turn/Wed, 06 May 2026 00:00:00 +0000https://mavai.org/signals/2026-05-06-shewhart-toyota-and-the-probabilistic-turn/LLMs break software’s binary view of correctness. The discipline that replaces it already exists - it was built at Bell Labs, refined in Nagoya, and has been waiting for software to need it.https://mavai.org/signals/2026-04-19-deming-challenger-and-the-ai-watershed/Sun, 19 Apr 2026 00:00:00 +0000https://mavai.org/signals/2026-04-19-deming-challenger-and-the-ai-watershed/A watershed-moment essay on why AI amplifies, rather than creates, software quality - and why the responsibility rests with those who own the system.https://mavai.org/news/2026-03-20-welcome/Fri, 20 Mar 2026 00:00:00 +0000https://mavai.org/news/2026-03-20-welcome/AI systems are increasingly subject to regulatory scrutiny, yet the testing tools available to most teams were designed for a deterministic world. Mavai is here to change that.
