Summary

Clarify the two graph cloning modes in HugeGraph REST API (POST /graphspaces/{space}/graphs/{graph}):

1. Mode 1: Configuration clone: Clones source graph configurations only (via ?clone_graph_name=...). Clarifies that in PD mode, schema.init_template is inherited and applied if configured on the source graph.
2. Mode 2: Schema clone (Server API 0.73+): Synchronously copies PropertyKeys, VertexLabels, and IndexLabels within the same graphspace (via POST /graphspaces/{space}/graphs/{name}/schema-clone?source=...). Automatically clears schema.init_template to copy the actual schema.

Key notes documented:

• Source graphs with EdgeLabels are currently rejected before target creation because some backend stores cannot reliably recover edge label hierarchy metadata.
• Schema cloning is non-atomic; if cloning fails after graph creation, the partial target graph must be inspected and deleted before retry.
• Removed legacy external fork links and streamlined documentation layout following OINK guidelines.

Blocking: no. Summary: The schema-clone section matches the merged GraphsAPI.cloneSchema and GraphManager.cloneGraphSchema behaviour, but it links a closed fork PR and the config-clone note misses the PD-mode schema template case.

Thanks for the review @bitflicker64! Updated:

1. Removed the closed fork PR link.
2. Added note on PD-mode schema.init_template inheritance for configuration cloning, and noted that schema cloning automatically clears the template to replicate the actual source schema.
3. Aligned path parameter naming (graph) and wrapped prose within 160 characters across English and Chinese docs.

Blocking: no. Score: 9/10. Summary: The schema-clone and configuration-clone sections match GraphsAPI.create, GraphsAPI.cloneSchema and GraphManager.cloneGraphSchema on master, including the PD-mode schema.init_template note, and the EN and CN pages agree; both earlier review points are addressed.
