The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

spin-induced tidal dissipation enters the gravitational-wave phase at 2.5 post-Newtonian order and carries a logarithmic frequency dependence, so it is not degenerate with the coalescence phase

C2weakest assumption

the most general, low-frequency, linear tidal response compatible with rotational symmetry is sufficient and accurate for the dissipative effects considered

C3one line summary

Spin-induced tidal dissipation in compact binaries enters the gravitational-wave phase at 2.5 post-Newtonian order with a logarithmic frequency dependence.
