Signature Moves

• Reference lock through computation pressure.
• Long-game attrition through computation pressure.
• Coalition pivot through computation pressure.

Timeline

• Modern: Alan Turing enters the record through computation leverage.
• Peak pressure: Codebreaker Architect status stabilizes across europe memory systems.
• Long aftershock: debates about computation and cryptography remain active in later eras.

Major Actions

• 1. Alan Turing: Changed the operating assumptions of communication, industry, or computation.
• 2. Alan Turing: Made an abstract system usable enough to alter later infrastructure.
• 3. Alan Turing: Left a framework that later builders expanded, standardized, or contested.

Controversies

• 1. Alan Turing: Credit disputes often widen once collaborators, financiers, and institutions are considered.
• 2. Alan Turing: The inventor myth can hide supply chains, labor, and the politics of adoption.
• 3. Alan Turing: Transformative systems may produce benefits and downstream harms on very different timelines.

Card Notes

• Primary pressure vector: scholarship and endurance.
• Representation policy remains portrait allowed.
• This card record is seeded as a concise prototype entry and expects future source expansion.
