Inverse of Assert. Emits true when at least one wire is falsy at the selected moments. Sibling of Any (at least one wire truthy) and Assert (every wire truthy).

​
Inputs

  • Data / default in — the wires to test.
  • Date — optional. When wired, evaluation happens at that exact date and the As-of moments setting is ignored.

​
Configuration

  • As-of moments — pick any non-empty subset of Today, Oldest, Latest, Latest defined. Each wire is evaluated at every selected moment; the wire passes if the value is falsy at any of them.
  • Use loop date — shown only inside a loop, on by default: each wire is narrowed to the iteration’s date and the As-of moments are ignored. Turn it off to use the As-of moments even inside the loop.
  • Collapse IDs — off by default. On, every ID a wire carries is pooled into one lane before the wires are compared.

​
Outputs

  • Result — one boolean per dated-property id seen across the inputs. For the typical single-id case, this is one DP.

​
Truthiness

nil, false and an empty string count as false; every other value, 0 included, counts as true.
