Manifests and receipts unchanged. Each of the 8 group-A identity tests now
extracts its manifest's recorded commit and verifies hashes there instead of
against the current checkout. Tamper assertions and runner source refusals are
kept; missing recorded history is an explicit failure, not a skip or repin.
Names the exact SRT/MRT parity tests and their sub-case scope (SRT: one
of 18 sub-cases, unidentified; MRT: 12 sub-cases, default outlet settings,
with the runs that recorded the pass), cites blocks.py:134 for tile
divisibility, labels refinement.py:457 as the fine-boundary re-check, and
says 'measured at 36ffc8b1' for the Taylor-Green observation.

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.

Copy tests/integration/test_checkpoint_bodies_gpu.py byte-for-byte from 34b30c434f. Base c95a7baae4. No production or dependency changes. GPU execution is deferred to the assigned executor.
One page listing supported settings, each with the guard enforcing it
(file:line at c95a7ba) and the existing tests exercising it. Measured
observations are labelled by their exact tested case (SRT strict-parity
1/4320 values ~2 ULP with unresolved cause; V3 TG constant explosion
aggregate; curved-wall r1 pilot; V4 NOT_STEADY), not stated as general
bounds. Documentation only.

The pinned BUILD_SOURCES are the a135252 qualification build inputs.
generate_config hashes the whole kernel snapshot, so after K1/K2 the
working-tree kernels (legitimately) no longer reproduce them. The test
now archives src/CelerisLab/lbm/kernels at NUMERICAL_REVISION and points
compiler_v2._KERNEL_DIR there; config headers are still rendered by
today's compiler. BUILD_SOURCES and the equality assertion are unchanged;
each size is a subTest; a missing NUMERICAL_REVISION fails (no skip).

surface_link_velocity already runs jet_link_shapes; CurvedLinkSoA.
assign_surface and _prepare_blocked_boundary then ran it again with the
same jets and hits to fill the host jet cache. A private _surface_links
returns (velocity, aperture, shape, jet_id) from the one call; both
callers use it. surface_link_velocity keeps its two-value public
contract (now a thin wrapper). Same values, same validation order, same
cache contents; host geometry preparation only.

Drop legacy constructor prose (child=/mutual exclusion), retarget
README and fixed_three_level_multipatch examples to refinements /
level_blocks, and fix stepper error/doc strings that still named
fine_block/base_block or a fixed gap >= 4 (unions use dependency
closure). Wording only; no behavior change.
Removes the legacy entry points now that every caller is migrated:
FixedPatchStepper(cfg, *, context, refinements, coarse_boundary,
level_blocks, level_objects, level_jets, observe_*, explosion) and
initialize(*level_g). Deleted: positional bounds, fine_block, base_block,
fine_objects, jets, child, child_block, child_objects, child_jets,
child_rectangles_in_parent, initialize(coarse_g/fine_g/child_g),
_legacy_levels and _initial_levels. Docstring, README and docs describe
the level lists. Compatibility views (patch, fine_boundary, ...) and the
PeriodicPatchStepper alias are unchanged (separate follow-up).
Error -> rule table (legacy keyword check -> level-list rule now firing):
- several patches without fine_block/base_block -> _check_levels
'several patches require fine_block and base_block' (unchanged rule)
- base_block without fine_block -> 'a blocked level requires blocked
refined levels below it'
- nested child without all blocks -> 'three or more levels must all be
blocked' / 'a blocked level requires ...'
- fine_objects/jets with a nested child ('only on L2') -> 'bodies/Jets are
supported only on the finest level of a nested hierarchy'
- child_objects/child_jets without a nested child -> 'level_objects/
level_jets needs one entry per level'
- scalar child with several L1 patches ('scalar child requires one parent
patch') -> hierarchy 'a scalar child requires a scalar parent'
- child vs child_rectangles_in_parent mutually exclusive -> no level-list
equivalent (cannot be expressed); covered by the new explicit
RemovedLegacyAPI test: removed keywords and positional bounds raise
TypeError before any context use, initialize has only *level_g.
The InitialLevels test of the removed adapter is replaced by that test.

One local levels(bounds, blocks, objects, jets, **rest) builds the
two-level lists; run_steps and every rejection case use it. All five
before-CUDA rejections, the margin and one-jet checks keep their inputs.
Assertions unchanged.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Dense root + blocked fine level is level_blocks=[None, block]; bodies go
to level_objects[1]. Both before-CUDA rejections (non-dividing and
malformed fine block) keep their inputs. Assertions unchanged.

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.

KW becomes levels() (scalar L1 + scalar L2, per-level blocks, objects,
Jets). All rejection cases are kept per level. Two cases change branch:
L2 bodies/Jets with no nested child (legacy 'child_objects/child_jets
require a nested child') are now an entry for a level that does not
exist ('needs one entry per level'); several L1 patches + scalar child
now meets 'a scalar child requires a scalar parent'. Both still reject
before CUDA. Assertions unchanged.

test_refinement_mrt_gpu, test_shifted_jets_gpu and
test_refinement_blocked_base pass refinements/level_* lists. The three
blocked-base rejection cases keep their inputs per level; base-only
blocks now meet the level-list rule (blocked refined levels below) where
the legacy keyword check fired before. Assertions unchanged.

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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
test_refinement_gpu (incl. PeriodicPatchStepper alias calls),
test_channel_root_gpu, test_fine_surface_gpu, test_shifted_remap_gpu,
test_runtime_child_remap_gpu and test_refinement_three_level_multipatch_gpu
pass refinements/level_* lists; scalar and set children map to the second
refinement entry exactly as _legacy_levels did. Assertions unchanged.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
test_shifted_jets, test_shifted_storage, test_raw_exchange and
test_channel_root pass refinements/level_* lists; examples
fixed_patch_jet and fixed_periodic_patch pass refinements=[BOUNDS]
instead of the positional bounds. Assertions kept; the shifted-storage
case base_block-without-fine_block now expects the level-list rule
'blocked refined levels below' (same constraint).

KW (legacy base/fine/child blocks + child_rectangles_in_parent) becomes
levels(): refinements=[PARENTS, CHILDREN], level_blocks, level_objects,
level_jets. Every negative case is kept and expressed per level (child
rectangles, per-level blocks); the L1-body case now expects the level-list
rule's message 'only on the finest level' instead of the legacy keyword
message 'only on L2' (same constraint).

The module-level import of CelerisLab.lbm.block_stepper loaded
pycuda.driver into the shared test process, unlike the other CPU host
tests (which load mocked copies via AST). find_spec gives the source path
without the import. Test content and assertions unchanged.

run_refined_dfg, run_dfg_re20, time_window_dfg, time_refined_dfg,
run_jet_circle_cv and examples/fixed_patch_circle pass refinements /
level_blocks / level_objects / level_jets instead of bounds, base_block,
fine_block, fine_objects and jets. One-to-one with _legacy_levels: same
rectangle (FixedPatch2D frame), same blocks, bodies and Jets.

The only in-library caller of the legacy constructor keywords now passes
refinements=[L1 bounds, L2 set], level_blocks=[base, fine, child],
level_objects=[(), (), child_objects], level_jets=[(), (), jets] -- the
exact lists _legacy_levels produced for it. Legacy keywords stay until
every caller is migrated (final P1 commit).

Review follow-up (non-blocking items): a launch failure on the second of
three steps fails closed without the batch wait, keeps step_count at its
entry value and blocks download; the docstring now states, as for
FixedPatchStepper, that async faults surface at the single wait.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Same change as the reviewed FixedPatchStepper end-sync (cherry-picked
ad1d82c+512dcc9 above): the n steps are enqueued in order and the host
waits once; step(0) launches nothing; step_count advances after the wait
and keeps its entry value on failure. Launches, buffer roles and bits are
those of n step(1) calls. Mocked-driver host test covers the single
wait, launch/role equality with n step(1), step(0) and failure.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Enqueue all n base intervals in order on the one stream and synchronize
once before returning (step(0): no launch, no wait). step_count, the raw
exchange ledger and an open window are published only after that wait;
any failure leaves step_count at its entry value and invalidates both
ledgers. Async device errors are no longer attributed to an interval;
the docstring says to use step(1) loops to localize one. Launch order and
buffers are unchanged. Adds a mocked-driver host test of the contract.

BlockStep (slot-reservoir wall rows) and BlockChannelStep computed the
global cell of a block-window cell with the same four lines.
block_global_xy (core/layout.cuh, 2D, __forceinline__) now holds them;
both kernels call it with their own domain width. Same integer
operations: no numerical, ABI or scheduling change. The slot-reservoir
kernel layout is unchanged (no split).

BlockStep, BlockChannelStep and refinement.cu patch_collide each carried
the same compute_rho_u -> omega clamp -> collide_mrt_no_force sequence.
collide_mrt_unforced (collision_mrt.cuh, __forceinline__) now holds it
once; the three sites call it. Same operations in the same order: no
numerical, ABI or SRT change. The host source contract now requires one
helper definition and exactly one call per file, and forbids the old
inline sequence.

Supersedes 71221837. Samples every t* 0.5 (interval-mean forces), trailing
t* 50..60 window (21 samples); range <= 10 % and |slope*window| <= 2 % of
each official band width. Verdict on the window mean with the distance to
the nearest band edge. Our engineering rule, frozen before any run.

(cherry picked from commit 869d60d78e)
Samples every 0.5 s at synchronized root steps; trailing 5 s window (11
samples); range and |slope*window| each at most 1 % of the official band
width. States the fluid-on-cylinder force sign, reports cd_positive,
defaults to the refined case and uses the review's label.

Reuses the pinned Re100 runner and helpers unchanged; sets only the
lattice viscosity for Re 20. Reports Cd, Cl and p_diff (dp * 0.04 for
U = 0.2 m/s), a steady rule frozen before any run (window ranges at most
a tenth of each official interval width) and no interval verdict when
not steady. Declares the pressure-NEQ outlet and Zou-He inlet deviations.
