Online RootFS growth
On growth-enabled images, Sandbox0 automatically expands the writable RootFS as free space runs low, within a configured sparse logical ceiling up to 64 TiB. Agent processes keep running. Growth is enabled in the qualified Cloud region; confirm activation for other regions. Existing images and snapshots retain their captured storage geometry. The ceiling is logical capacity, not preallocated host disk.
The reviewed Claw2Agent pages do not publish automatic whole-RootFS expansion, disk ceilings or an installed-system retention contract. Those capabilities remain unverified rather than absent. Sandbox0 exposes a durable writable RootFS with online growth on enabled templates; the surrounding OpenClaw service still needs implementation.
