Examples

• Create a layer:

  # Start an isolated writable view over the selected base root.
  ti fs create-layer --file-system-id <file-system-id> --base-root-path /workspace --layer-name agent-task
  

• Create a restore-safe tagged layer:

  # Request durable layer behavior and attach task metadata.
  ti fs create-layer --file-system-id <file-system-id> --base-root-path /workspace --durability-mode restore-safe --tag task=review
