Six routes in, depending on what you already believe.
Two hundred files is a lot to be handed at once. Pick a route. Every file is graded the same way whichever door you come in by, and the method explains what the grades mean.
IF YOU THINK NONE OF THIS IS REAL
Start here. Every file below is graded CONFIRMED, and confirmed does not mean plausible. It means a court, a congressional committee, a declassification or the organisation's own paperwork settled it. These are not the arguable ones.

Also start here. These are graded DEBUNKED, and several were debunked by the same kind of evidence that confirmed the files above. A grading system that never returns a negative is not a grading system.
OSA-026THE MOON LANDING HOAXDEBUNKED382 kg of moon rock, and a Soviet audience that never cried fake OSA-027FLAT EARTHDEBUNKEDSettled by Eratosthenes with two sticks; reopened by recommendation algorithm OSA-109PILTDOWN MANDEBUNKEDA human skull, an orangutan jaw, and forty years of citations OSA-033THE PROTOCOLS OF THE ELDERS OF ZIONDEBUNKEDThe most consequential proven forgery in history OSA-199SLENDER MANDEBUNKEDA fictional creature with a documented author, and a real attempted murder OSA-196THE MANTELL INCIDENTDEBUNKEDAn Air National Guard captain flew too high after something he could not identify OSA-078THE AMITYVILLE HORRORDEBUNKEDA real massacre, then a haunting invented over wineTHE ONES NOBODY HAS RESOLVED
Graded OPEN, CONTESTED or UNVERIFIED, which are three different kinds of unfinished: nothing settled it, the evidence points both ways, or the central claim has never been tested at all. Not for want of looking, which is what separates these from a mystery nobody has examined.

COOPEROPENThe only unsolved commercial skyjacking in U.S. history OSA-008DYATLOV PASSCONTESTEDNine hikers, a tent cut open from inside OSA-046THE SOMERTON MANOPENA body on an Adelaide beach, a scrap of Persian poetry, an uncracked code OSA-038THE ZODIAC KILLEROPENFive dead, two survivors, and ciphers mailed to the press OSA-007THE WOW!

The pattern the archive keeps finding. In each of these the official denial came first, held for years, and was retired by a document rather than an argument.
OSA-012THE GULF OF TONKIN INCIDENTCONFIRMEDThe attack that launched a war didn't happen OSA-052OPERATION AJAXCONFIRMEDThe CIA–MI6 coup that removed Iran's elected prime minister OSA-114CRYPTO AGCONFIRMEDHalf a century reading the secret traffic of allies and adversaries alike OSA-115OPERATION SHAMROCKCONFIRMEDThe telegraph companies gave the government copies of everything OSA-103THE GUATEMALA EXPERIMENTSCONFIRMEDAmerican researchers infected Guatemalans with syphilis on purpose OSA-123THE PLUTONIUM INJECTIONSCONFIRMEDHospital patients injected with plutonium to measure how the body handles it OSA-164THE TORTURE REPORTCONFIRMEDThe CIA's detention programme, documented by the committee overseeing itWHEN AN INDUSTRY KNEW AND SOLD ANYWAY
Not governments. Companies, with internal research that said one thing and public statements that said another, sometimes for forty years.
OSA-017THE TOBACCO INDUSTRY COVER-UPCONFIRMED"Doubt is our product", the archetypal proven corporate conspiracy OSA-106TETRAETHYL LEADCONFIRMEDSeventy years of leaded fuel, and the science bought to defend it OSA-127THE SUGAR RESEARCH PAPERSCONFIRMEDAn industry bought a Harvard review and shaped fifty years of dietary advice OSA-128C8 AND THE FOREVER CHEMICALSCONFIRMEDThe company knew for decades, and the science it hid was its own OSA-066PURDUE PHARMA & OXYCONTINCONFIRMEDAn addiction claim built on a five-sentence letter to the editor OSA-172THE ASBESTOS PAPERSCONFIRMEDThe industry's own correspondence, produced in discovery OSA-173MINAMATACONFIRMEDMercury poisoning of a Japanese fishing town, concealed for a decade after proofIF YOU HAVE TEN MINUTES AND WANT THE STRANGEST ONE
No argument, no pattern. These are simply the files that are hardest to put down.
