Test-side only; no production, manifest or pin change. Group A identity
checks (test_source_pin and the jets.py pins) are unchanged and stay
failing as recorded.
B test_refined_dfg: receipt/plan fixtures load the frozen manifest JSON
that verify_source returns for a matching tree (frozen_manifest), and
the two manifest-selection assertions call verify_source with only its
working-tree hash comparison neutralised (selected_manifest), so the
malformed/collision/observation-mode/checkout receipt checks run again.
test_source_pin remains the single identity check.
C test_channel_root: int(owner)-1 (uint64-int became float on NumPy 1);
test_shifted_storage: FP32 NaN fill so the arrays stay FP32. Both reach
the intended immutable/representation/FP32/density checks.
D test_block_stepper fake gets _ddf_shifting; test_fine_surface_gpu sets
_boundary_hosts/_level_jets instead of the read-only fine_boundary view;
test_refinement_followup fake_backend sets _layouts/_ddf_shifting/
_level_cfgs instead of the read-only fine_layout view (as reviewed in
32da2d73).
E test_kernel_contracts_reject_before_upload: an inconsistent pair tau is
now first rejected by the hierarchy chain check; the test asserts that
rejection, then bypasses _check_chain to prove the per-level omega/tau
guard still rejects, and asserts no mem_alloc/memcpy_htod in either case.

At the half-integer center the -0.1/-0.5 circles were already rejected
as unresolved, so the case did not exercise the finite/positive-radius
guard; an integer center makes the squared radius mark one solid cell.

_static_circles now checks finite center/radius and radius > 0 before
build_flag_mask (a negative radius squared to a one-cell solid), matching
prepare_fine_boundary. objects is converted to a tuple before the
emptiness test so an empty iterable takes the body-free path.
CPU tests: negative/NaN radius and nonfinite center rejected before CUDA;
empty iterator skips circle preparation.

blocks.cu: BlockCurvedBoundary passes the receiver-local core cell and the
block-offset fi to the unchanged apply_bouzidi_link (Uw=Vw=0, obs=nullptr),
so k_s and the q<1/2 donor follow the window image the next pull reads.
BlockStep takes nullable block-cell flags; solid cores store NaN each step.
Adds core/flags.cuh, core/obs.cuh and boundary/curved_boundary.cuh.
block_stepper.py: objects=() accepts stationary passive circles only; host
preparation rejects before CUDA: non-circle/moving/actuated/sensor roles,
overlap, domain-edge contact, and any fluid core (all rows/columns, periodic
neighbors) whose pull from a solid lacks exactly one cut link. Uses
map_cut_links for unique receiver owner/local writer. Order per step:
halo copy -> BFL -> pull/collide, no copy in between. Fluid-only
initialize validation; solids NaN.
Tests: CPU rejections/tables; GPU 32x24, nu .1, 8 steps, circle
(15.5,11.5) R4.3 with halo-write and halo-donor presence asserted,
1x1/2x2/4x2 bit-identical, finite fluid/NaN solid, FP64 BFL+pull/SRT
<= 3e-6 on fluid; drift reported. Body-free gate unchanged.

close() now clears _module (initialized to None) inside the active
context together with the function references; lifecycle test asserts
it is retained on failed activation and cleared after close.

step() reads _dst/_src before the launch; without them the failed-launch
test raised AttributeError instead of the intended RuntimeError.
