Startup Signal · Issue #142
Five for your Sunday.
Morning. A coding model that reviews its own pull requests, a laptop redesign that finally fixes the one complaint everyone had, and a supply-chain scare that sat quietly for fourteen months before anyone noticed. Get comfortable — this one runs long.

AI · Deep dive
Anthropic's newest model can review its own code — and catch its own mistakes.
We fed it forty real pull requests pulled from open-source repos. It flagged bugs in its own output six times before we'd even asked. Here's where that genuinely saves a team time, and where it just moves the work somewhere else.

Hardware · First look
The redesigned Framework 13 finally fixes the one complaint everyone had.
A stiffer hinge, a brighter 120Hz panel, and a battery that survives a full transatlantic flight without a charger. We've carried it for two weeks — here's what's genuinely better, and what Framework still owes its earliest buyers.

Security · Investigation

Open source · Funding
A maintainer's weekend side project just closed a $12M seed round — without changing its license.
