Computation — Riemann hypothesis

• q1/ replays the published heat-flow arithmetic and a historical Lehmer-pair calculation, then checks the retained logs from a resource-light audit of an off-arXiv upper-bound candidate.
• q2/ completes the independent certification of Gomila's candidate: $\Lambda\leq893927/5000000=0.1787854<1/5$. It retains two complete finite verifications, fresh analytic computations, and a review of the theorem transfer. Start with q2/CLAIM.md and q2/NOTE.md.
