- _exchange_spacing/_exchange_centers (two more per-level lists, only read
for levels that have a boundary) become _BlockedBoundary.spacing/centers.
- _level_blocks dropped: remap_finest reads each layout's own .block.
- _device_boundaries -> _boundaries: the record holds host geometry, tables,
Jets and device handles, so 'device' was misleading (the old host-only
_boundaries list no longer exists). Tests migrated mechanically.
Remaining per-level lists (_layouts, _level_cfgs, _leaf, _state, _boundaries)
are the immutable construction plan, built before the memory preflight and
kept after close; _levels holds device handles only and is cleared on close.

Conflicts (6 files): tests took the caller-migration side, then the
358bed1 renames (_level_boundaries -> _device_boundaries); run_refined_dfg.py
kept ae53fad (same jet_interval level= repair plus blocked_coarse_tables on the
current-checkout path). Follow-up renames in 5 auto-merged tests;
blocked_fine_tables imported from refinement_tables. Frozen drivers untouched
(run_jet_circle_cv.py, check_projected_pairs.py remap_child, historical DFG path).

- Coarse/fine name the two members of any pair (Hierarchy docstring); only the
misleading blocked_base_tables -> blocked_coarse_tables. prepare_fine_boundary
and blocked_fine_tables keep their pair-relative names.
- Depth-1 static circles use the integer-NODE frame (unchanged behavior); the
root EDGE frame applies to refined levels only. Contract text corrected.
- _kernel_configs documents why it stays distinct from Hierarchy.configs.
- Drop the stale re-export comment; two tests import table builders from
refinement_tables. Mechanical caller renames for this delta only.
No numerical code or config derivation changed.

- test_exchange_window and test_raw_exchange_gpu fine(): dense root becomes
a (12, 8) blocked root (fine(None) stays only for the dense reference test
that D2 retires);
- jets: G1/G3 compare blocked layouts against the FINE_BLOCKS[0] reference
(blocked root); the dense run is a separate leg D2 removes; G2 legacy
actuation vs Jet on the blocked reference; CPU fixtures use a blocked root;
- test_refinement_blocked_fine.raw reads every level through its layout;
- test_fine_surface_gpu: new test_fine_surface_blocked_matches_uniform_four_hops
(fine ROI after each of four hops vs the uniform 48^2 solver with the same
tolerances, blowing/suction mass sign from raw exchange, zero actuation ==
passive bit for bit); the cross-interface donor rejection passes tiles.
The dense hook/ledger/audit probes in test_fine_surface_four_hops and the
dense SoA fault tests stay until D2 retires them by name.

Restores the PeriodicBlockStepper safeguard dropped in 8e1feff, for all
FixedPatchStepper levels: both G buffers, halo pairs and boundary columns
of every level are compared with cuda.mem_get_info() before the stream,
any module or any buffer exists, raising MemoryError('level buffers exceed
free device memory'). Transfer tables are not counted (lower bound).
Tests: the single-level MemoryError case is back beside the param-layout
check (no stream, no allocation); host test_single_level covers depth 1
and depth 2 (no stream, build or allocation) and the wait failure after a
good step (count stays 1). Driver-mocking fixtures report ample free memory.

The package already exposed it as CelerisLab.cuda.compiler; the module now
has that name and every tip caller, doc and current-tree test imports it
directly (no alias).
Historical-revision tooling is not edited: the Taylor-Green harness
(run_case.py, hash-pinned check_projected_pairs.py, assess receipts) only
runs against a135252, whose package has cuda/compiler_v2.py, and the J
campaign runners and dated docs describe past trees. Its two current-tree
tests now import that package from git (historical_package) instead of the
tip, and the kernel-root test first checks the accepted case.

test_exchange_window, test_raw_exchange_gpu (one fine(block) helper for
the repeated circle+jet construction), test_refinement_jets,
test_multiple_pinned_remap_gpu and test_pinned_body_remap_gpu pass
refinements/level_* lists. Dense fine levels stay level_blocks=[None,
None|block] as before. Assertions unchanged.

Caller obj_id 99 spanning 2x2 fine blocks: driven rows carry the single
remapped owner 0 across several block ids, accepted; source id unchanged.
Caller ids (99, 7) under one tube are rejected at amplitude 0 and .002
on the 32x24 fixture; source ids unchanged.

surface_link_velocity (the shared host check used by CurvedLinkSoA,
ObjectManager sync, prepare_fine_boundary and FixedPatchStepper) now
rejects a jet whose selected cut links carry more than one body id, at
any amplitude, before uploads. Identity is the scene-wide body id of the
physical cut-link list, so one body spanning storage blocks stays valid.
No body selector; empty-selection semantics unchanged.
Tests: two bodies under one jet rejected (amplitude 2e-3 and 0) on the
Simulation/manager path and on the fine path; separate jets on separate
bodies accepted on both; one fine body crossing 2x2 block seams accepted.

FixedPatchStepper.set_jet_amplitude validates index/amplitude and builds
the new rows before touching the device; invalid input leaves the
instance usable. A copy/sync error marks it failed (as initialize/step/
download do) and re-raises; host state (_jets, blocked velocity table)
commits only after a successful upload. CurvedLinkSoA.set_jet_amplitude
likewise uploads a new array first and commits jets/surface_velocity
afterwards. Focused mocked-driver tests for dense and blocked copy
failure, invalid input and IndexError.

FixedPatchStepper(..., jets=()) passes jets (coarse cell-edge frame, as
fine_objects) to prepare_fine_boundary, which runs the shared assignment
checks before CUDA. Dense fine path: assign_surface with jets and the
boundary's true hits. Blocked path: surface_link_velocity with jets/hits;
unit-amplitude shapes cached. set_jet_amplitude (new/ready only) validates
first, then rewrites the dense SoA column or the blocked jet rows and
re-uploads only the velocity buffer after a stream sync. Scheduling,
kernels and launch ABI unchanged.
tests/validation/multigrid/test_refinement_jets.py: mocked-driver CPU
checks and frozen GPU gates G1-G3 (layout identity, jet vs legacy <=1e-6,
amplitude switch).
