Grateful Dead Codexery — Data & Quality

We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.

Recent findings (audit lane, verbatim)

Ron McKernan — McKernan's last show with the Grateful Dead was June 17, 1972, but he actually performed with the band on June 24, 1972, at the Hollywood Bowl, which is widely considered his final show.

Bill Kreutzmann — The claim that Kreutzmann is 'the only surviving member of the original lineup who played nearly all 2,300 Grateful Dead shows' is misleading because Bob Weir is also a surviving original member, and Phil Lesh was alive at the time of likely writing.

Bill Kreutzmann — The side project 'Kokomo' was formed in the early 1990s (1991–1993), not the 1980s.

Donna Godchaux — Donna Godchaux was born Donna Jean Thatcher, not Godchaux

Donna Godchaux — She officially joined the Grateful Dead in March 1972, not 'shortly after' September 1971

Jerry Garcia — The entry states the Jerry Garcia Band was founded in 1976, but the band's first official performance under that name was in December 1975.

Jerry Garcia — The entry says Clarence Clemons guested with the band on tour for a brief time in 1989, but Clarence Clemons actually toured with the Jerry Garcia Band in 1988.

Klingon Empire — The entry states 'The text incorrectly states that Burnham's parents were killed by Klingons; in fact, they were killed by Vulcan extremists.' This is a factual error in the entry's own correction: In Star Trek: Discovery canon, Michael Burnham's parents were

Klingon Empire — The entry states 'Burnham served about six months of a life sentence for mutiny before being recruited by Gabriel Lorca.' In canon, Burnham served approximately one year (not six months) of her life sentence before being recruited by Lorca.

Jerry Garcia Band — The first official show of the Jerry Garcia Band is stated as January 29, 1976, but the widely accepted first official show under that name is January 30, 1976, at the Keystone in Berkeley.

Jerry Garcia Band — The claim that the band's roots trace back to 1970 local club gigs featuring Garcia, Merl Saunders, John Kahn, and others is misleading; Garcia and Kahn began playing together in 1970, but the specific quartet with Merl Saunders did not form until 1971, and th

Winterland Ballroom — The entry states Winterland opened on June 29, 1928, but the widely accepted date is June 28, 1928.

Winterland Ballroom — The entry claims the Grateful Dead played 73 times at Winterland, but the widely accepted count is 74 shows.

Bill Graham — The entry states Graham died in a helicopter crash near Vallejo, California, but the precise location is typically given as near the Concord Naval Weapons Station in Contra Costa County.
