A uw.function.expression whose value is zero is folded out of expressions by sympy at construction, so a runtime constant that starts at zero never updates

uw.maths.Integral, BdIntegral and CellWiseIntegral read every expression constant as zero: the kernels are compiled with PETSc constants that are never set

Cell size: one definition, one name — three are in play, the docstrings describe a fourth, and get_*_radius() is partition-dependent

Swarm.advection fails on a rank that holds no particles: estimate_dt reshapes an empty (0, 1, dim) velocity array with -1

Reloading a checkpointed mesh built with refinement>=1 gives a corrupt DM: the integral of 1 is 0.07 on a unit square and the kinetic energy is negative

mesh.cell_size() is partition-dependent: the per-cell radius comes from a kd-tree over the rank's centroids, so cells at partition boundaries get a different size on each rank count

SLCN on the annulus: the inner-wall temperature gradient is 6% steeper than the heat flow the interior carries (a first-cell artefact at the curved wall)

preconditioner="fmg" is inert on the semi-Lagrangian solvers: their solve() pre-runs setup and skips the base _build resolution

SLCN trace-back gives a partition-dependent answer (1.6% at np=8 on a 128x128 level set)

The co-located multigrid tail fails at np=3 on the 3-D width network: a Galerkin coarse operator with a missing diagonal, and a 10% slip error

Placement gathers far more than the surgery needs, onto one rank for the whole network, and never sends it back
