Mastra PlatformSandbox Adds Process Controls

Mastra’s PlatformSandbox now includes a full background-process manager through @mastra/platform-workspace, enabling developers to spawn commands, stream output, list jobs, reattach by PID, and stop processes. The update makes sandbox environments practical for dev servers, file watchers, and long-running agent workloads.

// ANALYSIS

This moves sandbox execution beyond one-shot commands toward a durable development runtime.

–Live stdout and stderr streaming makes background jobs observable without polling
–PID-based listing, reattachment, and termination support recovery across application restarts
–Long-running processes fit agent workflows that need servers, workers, or watchers to stay alive
–Periodic stream reconnection is useful, but output loss during reconnects remains an operational caveat
