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.

FixedPatchStepper and the PeriodicPatchStepper alias are called with
refinements=[bounds] instead of the positional legacy bounds (same
_legacy_levels result). Assertions, including the before-CUDA and
four-cell/omega/layout rejections, unchanged.

- GPU test: after hop 2 some INNER_GHOST populations are NaN (pulled from
OUTER poisoned on hop 1; 236 slots in pinned CPUREF); assert ACTIVE
finite and OUTER NaN, keep the full dense-vs-blocked raw value/NaN-mask
comparison.
- A 1x1 non-periodic fine layout has zero halo pairs: skip the halo table
uploads (CUDA rejects mem_alloc(0)); _fine_halo already skips launch.
CPU guard test with driver doubles.
- Drop the class-level fine_layout default; the followup fake backend now
sets fine_layout = None explicitly.
