Issues

• FAC patch in 3-D: a split fault's structural block is one LU per rank (one block wins in 2-D; 3-D cost unmeasured)

• Rotated Newton loop with a fault interface law: the velocity multigrid keeps the first iterate's operator

• custom_mg: an unsplit placed-ribbon coarse tail exhausts node memory before the first iteration

• Rotated path: FAC patch blocks run ILU(0), not the configured LU

• Units model: estimate_dt's crossing time and first accuracy estimate read dimensional mesh coordinates as model units (dt 3.4x too large, silently)

• custom_mg.build_transfers: a rank-local exception decides a collective retry

• custom_mg: last_builder_stats is module-global, and outside_hull counts nodes beyond a curved boundary's chords

• Rotated solve: the rotation-gauge projection is measured from the second assembly on an uncached solve

• Rotated solve: the cold-start datum lift sets the convergence reference to the lifted iterate's residual
