patch_gen::{stadium, graded_fractions}: the falsifier plate as a stadium O-grid
(semicircular ends r = half-thickness; 16 cells per end arc, straights graded
0.30 h -> h at 1.15, offset 6 h, 12 rows stretched 4x; 148x12 cells, every ray
a normal, worst non-orthogonality 4 deg). CurvilinearPisoSolver::surface_force
(+ PatchLoad): F = sum(-p_f S_f + mu (grad u + grad u^T)_f . S_f) on the wall
faces with the wall cell's LSQ gradients (wall Dirichlet in the velocity fit);
HELD on the phantom circle against the exact stress integral: 1.3e-2 / 6.3e-3 /
3.6e-3 at n = 32/64/128 (orders 1.05 / 0.81), 22x the staircase's accuracy.
OversetPisoSolver: the composite p' level pinned to zero mean over the active
cells every round (the coupled problem is pure Neumann; the temporal warm start
handed each step's level to the next — background pressure 1e7 growing 5e4 per
step on the falsifier; an unpinned level also inflated the relative Schwarz
stop); stall detection (no progress over three rounds = the inner solvers'
noise floor; 6560 of 150k steps burned the 20-round cap at n = 64, a 7.5 h
n = 128 march); schwarz_stalled in the result.
tests/overset_falsifier.rs (records; RTX_OVERSET_FALSIFIER_STRICT asserts the
registered gates, _LADDER runs dt/2 and dt/4, _TRACE the top-12 spike steps):
max spike 594 / 981 / 1720 N/m at dt / dt/2 / dt/4 (staircase 6490 / 12600 /
25600), rms spike 61-89 (810), far probe 502-1509 (7900), KE injection 0.16-0.21
J/m per event on the common cell set (2.6) — every large spike a ~104-cell
full-row reclassification; exponent -0.77 (-1.0). The registered 5% gate (8.75
N/m) is missed 68x: the overset's own reclassification impulse is the finding
(omni-cortex overset_metal_campaign.md §5.10); P3b = locate per cell, then the
fringe flux balance. tests/patch_stadium.rs, curvilinear_loads.rs,
overset_common::plate_patch.
