Wrap existing slots in new operations without dismantling what you've built in Value Composer.
Before wrap:
[Existing Transform] → Output
After wrap:
[New Conditional] → [Existing Transform] → Output
Use cases:
Null checks - Add safety around existing logic
Type coercions - Convert output format
Conditional logic - Apply filters to composed output
Iterative refinement:
Start with basic mappings, add complexity as requirements evolve. The operation is reversible - unwrap removes the parent while preserving wrapped content.
