LIVING PROTOTYPE · PROTOTYPE 1: PINELLAS PLANT
THE ROSETTA WEB™ — Interactive Evidence Network
Explore documented, partial, and unresolved relationships among facilities, materials, monitoring systems, organizations, military participation, and archival records. Pinellas Plant is the first public demonstration of the living network.
A networked history
The nuclear weapons complex was a system.
Rosetta Web studies movement and connection: contracts, people, materials, technologies, records, and occupational evidence crossing organizational and geographic boundaries.

Featured research tool
Explore the nuclear weapons complex geographically.
The Facility Atlas provides a geographic entry point into Rosetta Web, bringing facilities and sites into one navigable research environment while preserving the distinction between location and documented relationship.
Facility Atlas
Place is the starting point—not the conclusion.
Use the atlas to locate facilities and begin a documentary trail through organizations, operations, materials, shipments, workers, and records.
Research rule: geographic proximity does not establish an historical relationship. Connections require supporting evidence.

The connection is only as strong as the record behind it.
Rosetta Web does not fill documentary gaps by inference. It decodes the record, connects evidence across collections, triangulates independent sources, tests contradictions, classifies the strength of each relationship, and preserves the gap when the surviving record cannot support a conclusion.
Decode → Connect → Triangulate → Test → Classify → Preserve the Gap
Explore THE ROSETTA METHOD™ →Documented
Direct evidence establishes the relationship.
Documented — Aggregate/Purchase
Evidence supports a broader procurement or material relationship.
Indirectly Documented
Multiple records support the relationship.
Research Lead
Evidence warrants further investigation.
Unresolved
Evidence is conflicting or incomplete.
Missing-Record Target
A record should exist but has not yet been recovered.

April 1942: Mallinckrodt and the University of Chicago
Rosetta's inaugural featured document is a two-page secret Memorandum of Understanding dated April 23, 1942, recording an exploratory project, purification planning, and the developing relationship between Mallinckrodt Chemical Works and the University of Chicago.

Open Missing Evidence →Our evidence promise
Rosetta does not ask readers to trust its conclusions.
We provide the evidence necessary for readers to test them. Substantive findings must be traceable to identifiable evidence; contradictory evidence and uncertainty remain visible; and findings change when stronger evidence warrants it.
Research integrity: the private Rosetta Web Master Evidence system remains offline. Only reviewed, classified, and public-safe material is promoted to the public site.
