MARKLESS_STATE_DESTRUCTURE_DEFAULT_UNSUPPORTED
Graph destructuring defaults are not supported yet: a Markless compiler error.
Error from the compiler, while it builds your .tsrx files.
What happened
Markless prints the message, the reason, and a suggestion:
MARKLESS_STATE_DESTRUCTURE_DEFAULT_UNSUPPORTED: Cannot create graph alias "<localName>" from "<target>" with a default value.
A destructuring default must run only when the property value is undefined. The current graph alias artifact can represent a graph path, but not a fallback expression without changing JavaScript semantics.
Use an explicit computed() for fallback logic, or read the graph path directly without a destructuring default.

How to fix it
