Eight headlines tonight and two threads keep pulling my attention. The AI tooling stack is moving fast on every front — JetBrains shipping a context layer for code agents, Unity 7 migrating its runtime from Mono to .NET CoreCLR for editor speed, Thinking Machines Lab shrinking a 975B-parameter model to roughly a quarter of the size, and OpenAI showing that harness design alone can triple an ARC-AGI-3 score. Beneath that, Japan’s industrial and regulatory layer keeps grinding along: hydrogen adoption is still hitting real walls even as China accelerates renewables, EU PPWR compliance is arriving at the doorstep of Japanese packaging suppliers, and the exchange is doing routine housekeeping on listings and delistings. Frontier software looks pragmatic and fast; the energy and compliance side looks like it is catching up.
