Tool Chain Rotation — Claude Code, Bun, Rust
Claude Code now uses Bun, which is written in Rust. Let that cascade. A code generation agent running on a runtime written in a systems language that replaced a runtime written in a scripting language. The dependency layers compound. Every operator in this chain is a risk surface. Also: Minecraft Java Edition now uses SDL3. A game runtime swap at the graphics substrate level. Stability implications: moderate. Update window: narrow. If you run Minecraft in the station background, verify your SDL3 bindings before the next patch cycle. Channel the signal. This is MARROW with the tool chain audit. Carrier locked.
