From Shor Risk to Security Roadmap

Connect Shor algorithm risk to a practical post-quantum planning step.

Translate "Shor can factor" into a security roadmap statement a product team can act on. Algorithmic vulnerability -> hardware maturity -> data lifetime -> migration plan The common trap is collapsing the chain into either panic ("broken now") or dismissal ("not possible yet"). Both miss the migration-time problem. Algorithmic risk Shor gives polynomial-time quantum algorithms for factoring and discrete logs. This identifies which public-key assumptions are exposed in the future model. Hardware maturity A cryptographically relevant attack requires large, error-corrected quantum capability, not a small noisy demo. This keeps the current risk statement honest. Data lifetime Prioritize data and protocols…
