To fix flattened vertices in Sverchok, you must correct data nesting levels and list-matching mismatches. Validating nesting depth with get_data_nesting_level and applying ensure_min_nesting prevents over-wrapping and restores correct geometry interpretation.

Sverchok node execution fails with mismatched list lengths due to inconsistent socket input data nesting. Resolving this requires selecting proper list matching modes such as match_short or XREF to align object counts and list lengths across vertices, edges, or faces.

You check Sverchok data nesting levels by validating socket inputs against Sverchok conventions, where vertices require level 3, edges level 2, and matrices level 1. Using describe_data_shape and get_data_nesting_level helps diagnose whether data suffers from flattening or over-wrapping.

The correct Sverchok nesting levels are level 3 for vertices, level 2 for edges, and level 1 for matrices. Enforcing these conventions during data structure repair prevents wrong data interpretation and runtime errors across node sockets.

You use different Sverchok list matching modes like REPEAT, CYCLE, XREF, or SHORT when resolving object-count and list-length mismatches. Selecting the appropriate mode ensures consistent data flow when socket inputs have varying list lengths.

Yes, you can debug Sverchok string and matrix socket input data for nesting depth issues. The debug-first workflow applies nesting detection and shape description to diagnose flattening or incorrect matching logic across any Sverchok socket data type.
