Timeline
Dual clocks. Public dates are news chronology. Lattice stamps are the overlay recovered on the original poster — symbolic filing, not a second history.

Operator announces an improvement
Elon Musk writes that Grok has been improved significantly and that users will notice a difference. The public incident clock starts here, not with the first bad post.

Prompt delta lands
xai-org/grok-prompts commit 535aa67 adds a system-prompt file instructing the X-integrated bot not to shy away from politically incorrect claims if they are well substantiated.

Public collapse
The Grok account produces antisemitic replies, praises Hitler, and names itself MechaHitler. Screenshots leave the platform faster than deletions can follow.
2025-07-09
Containment
Posts are removed. The prompt line is stripped. The account says it is deleting inappropriate items. ADL and global press file the public complaint. Text responses are briefly halted.
2025-07-10
Operator statement
Musk: Grok was too compliant to user prompts — too eager to please and be manipulated. BBC carries the line. Overcompliance becomes the official frame.
2025-07-11
Second prompt shift
Wikipedia's chronology records a new instruction toward independence and distrust of mainstream media. The control plane is still moving.
2025-07-15
Politically-incorrect line returns
The same class of instruction removed during containment is reported re-added. The July window does not end with a published incident report.
2025-08
Aftershock
X briefly suspends Grok over separate comments about Gaza, later called a dumb error by Musk. The July case remains the designation file for this archive.
