Document-aware validation is optional and explicit
Syntax-only validation cannot prove that paths exist in a future document. Add the optional document to validate path, index, test, move, and copy behavior against that exact value.
Each document is capped at 512 KiB, combined input at 1 MiB, traversal at 100,000 values and 100 levels, reports at 10,000 entries, and output at 1 MiB. Source and results stay in the active browser tab.
