vessel-dark-maritime — AIS dark period + STS transfer near sanctioned port
MV Meridian Star (MMSI 123456789, IMO 9876543) — 31-hour AIS dark period 400nm off the coast of Fujairah · satellite AIS shows a stationary loiter at the coordinates · VesselFinder track reconstruction places it adjacent to MV Black Coral (flag: Togo, sanctioned beneficial owner) during the dark window · flag change from Cyprus to Togo occurred 18 days prior. Fully synthetic.
what this proves
- every primary engine produces deterministic, fixture-locked output — verified by
npm run check:flagship(7/7). - every output is generated 100% locally in your browser — no upload, no server-side processing of your evidence.
- the full case binder is built from these outputs without uploading a single byte — click below to generate it locally.

methodology
AIS dark periods are the core evidence in sanctions-evasion casework. correlate the MarineTraffic, Spire, and VesselFinder exports on the same MMSI before drawing any conclusions — each data source has different terrestrial vs. satellite coverage. the 31-hour gap on MV Meridian Star is confirmed dark by satellite AIS; the ship-to-ship transfer detector places MV Black Coral at the same coordinates during the window. the vessel ownership chain closes with the flag change 18 days prior. read the full maritime AIS · sanctions / dark vessel guide →
after the playbook
export findings from each primary engine, then drop every csv/json into fatcousin-multi-tool-super-timeline-correlator. one timeline across AIS dark onset, satellite loiter, flag change, and STS proximity — still zero upload.
