Validation happens before the result is exposed
Operations run sequentially against a clone. A failed test or invalid path stops the request and no partially changed document is returned. Prototype-modification paths are rejected.
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.
