Summary

  • backport perf(langsmith): cache large JuiceFS writes #918 to v16-stable
  • enable JuiceFS cache-large-write for the SSD-selected 300 GiB sandbox-host mount-pod cache
  • keep newly uploaded Firecracker rootfs blocks available for immediate same-node rereads
  • preserve the v16 chart structure and existing mountPodPatch override surface

Test Plan

  • helm unittest charts/langsmith (21 suites, 290 tests)
  • helm lint charts/langsmith -f charts/langsmith/tests/values/sandboxes-enabled.yaml
  • render the JuiceFS CSI ConfigMap and verify cache-large-write is scoped to the SSD-selected patch
  • regenerate charts/langsmith/README.md with helm-docs
  • git diff --check
