Hopf–Rinow adoption, layer 0: a self-contained, Mathlib-only leaf. Mathlib's Picard–Lindelöf gives only local existence; for a linear ODE V'(t) = A(t)V(t) with continuous bounded coefficient the solution exists on any compact interval. Builds against the sorry-free main; 0 sorries. Co-authored-by: Axel Delaval <axel.delaval@gmail.com> Co-authored-by: Spring-1211 <liuchunlei@pku.edu.cn>

Hopf–Rinow adoption — layer 0 of the dependency cone (from
feat/hopf-rinow).What: adds
OpenGALib/Riemannian/Geodesic/LinearODE.lean— global existence on any compact interval for a linear ODEV'(t) = A(t) V(t)with continuous bounded coefficient. Mathlib's Picard–Lindelöf only gives local existence; this supplies the global statement.Why safe: true leaf — imports only Mathlib, zero coupling; builds against the (now sorry-free)
main.Verification:
lake build OpenGALib.Riemannian.Geodesic.LinearODE✅; 0 sorries.Adopted from
feat/hopf-rinow; original authors credited via Co-authored-by.
