Reproducibility Guarantee
The same inputs, run through the same decisions, should always produce the same results. Reproducibility Guarantee is the system that makes this structurally inevitable: a Data Contract locks every assumption before the analysis runs, and Reproducible Output ensures every result carries a complete record of how it was produced.
What is Reproducibility Guarantee?
Reproducibility failures in science typically come in two forms: the researcher cannot reproduce their own results months later, or an independent group cannot reproduce them at all. Both failures share a common root cause — assumptions that were implicit rather than declared, and outputs that carried no record of how they were generated.
Licklider's Reproducibility Guarantee addresses both failure modes directly. The Data Contract forces explicit declaration of the analytical foundation before any test runs. The Reproducible Output layer captures every decision into human-readable Methods text, figure legends, and a machine-readable version snapshot — automatically, at the moment of export.
Reproducibility Guarantee has two complementary components: The Data Contract eliminates ambiguity at the start of analysis — declaring what each observation represents, how variables are structured, and what kind of outcome you are measuring. Reproducible Output eliminates ambiguity at the end — generating the Methods text, figure legends, and version records that allow any result to be re-traced.
Data Contract
Every analytical assumption that goes undeclared is a reproducibility risk. The Data Contract turns implicit assumptions into explicit, locked declarations that govern all downstream analysis. Three declarations are required: what the unit of observation is, how variables and identifiers are mapped, and what the outcome type is.
Reproducible Output
A figure without a complete Methods section is not a reproducible result — it is a claim without a procedure. Licklider's Reproducible Output layer auto-generates all the text required to make every result reproducible: the Methods paragraph, the figure legend, and the version snapshot.
