Core 1.55.0 lets Code Mode transports declare requiresSandbox: false, with the new @mastra/isolated-vm package supplying an in-process V8 isolate: no filesystem, network, or process access, reachable only through bridged external_* tools. The quieter fix matters more: the generated Code Mode instructions previously always claimed full sandboxing regardless of configured transport. The model was being told it was sandboxed when it wasn't.
