Draft 2026-W44

Proton's chief technology officer has published an engineering memo saying developers should direct AI models and rebuild the whole development process around them. It is a statement of intent: no numbers, no timeline, no named tools. Watch it as a checklist of questions, not as proof.

Claude Code 2.1.314 (30 October) adds a setting that makes its file-editing tools refuse any path outside the working folders, whatever permission mode is on. It does not limit shell commands. Adopt it if you run with relaxed permissions, and add a sandbox for the rest.

Claude Code's changelog says fast mode for the Opus 4.8 model is deprecated as of 30 October and will be removed on 30 November. After that, requests fail instead of falling back to the normal model. Flag it: check shared settings and automation, and move to Opus 5.5.
