Target Sum Builder
Build an exact number, date, or time target from a known entry and one deterministic completion.
Define the target
Digits stay fixed-width. Leading zeros remain part of the protected target.
The builder pads this entry to the target width, then calculates one exact completion.
Values stay in this browser. Nothing is sent to a server, placed in the URL, or included in analytics.

Two-path validation
The result is calculated with fixed-width decimal arithmetic and checked independently with BigInt before it is shown as exact.
