ClaudeandClaude Opus 5.5 653fd997a6 body: stage motion-record uploads in an owned page-locked buffer
memcpy_htod_async needs page-locked host memory. MovingTables allocates one
pinned FP64 buffer at construction (manager.py action pattern) and rewrites
it only when the records change; every upload is followed by a stream sync
in Simulation._run_moving before the next one, so no copy is in flight when
it is reused. The advance test fixture now binds the real LBMStepper.step.

ClaudeandClaude Opus 5.5 6f9e40caa3 simulation: a failed moving step also blocks direct stepper calls
Tests cover failures at the first upload, the step-group sync, the no_donor
check, the hold-record upload and its asynchronous sync: before the commit
point the target stays pending, after it applied matches the moved device;
in every case run and direct stepper reuse are refused.

ClaudeandClaude Opus 5.5 d50b8ba1be lbm: translating circles move with refill (S3a)
MovingCircleCells reclassifies swept-band cells from immutable old/new FP64
predicates: covered cells add their raw momentum and mass to diagnostics and
become solid; uncovered cells are refilled in all nine slots from donors
fluid in both geometries (mean density, NEQ from the best-aligned donor,
wall velocity at the cell), counting eq_only and no_donor. MovingCircleLinks
adds the translation velocity to the wall velocity. Simulation.run(1)
uploads the motion record, runs M1 then M2, synchronizes, rejects a nonzero
no_donor count and only then commits the target and uploads the hold
record; any failure marks the Simulation failed. Targets block direct
stepper calls and multi-step runs. get_flags reads device flags back when
translating circles exist. Contract section 10b.

ClaudeandClaude Opus 5.5 b920a303a4 simulation: keep the owner context active through moving diagnostics readback
moving_diagnostics is context_bound, so stream synchronization and the
DTOH copy run inside one owner activation. Tests: owner stays active
through sync and download; launch order moving -> static curved -> OneStep
with a real static link count and the buffer swap between steps.

ClaudeandClaude Opus 5.5 0f8a428f07 lbm: fixed-centre moving-circle cut links (S2a)
MovingCircleLinks computes the cut links of each translating circle from an
FP64 {cx, cy, r} table over its swept band (same q/hit/clamp/fallback order
as build_cut_links, explicit _rn operations) and applies the unchanged
apply_bouzidi_link with spin wall velocity. obs keeps its contract; a
separate per-body diagnostics buffer records CME, the Wen term u_w*dm,
link_dm and the link count. Moving tables are built at initialize and
attached to the stepper, which then launches the kernel before the static
curved kernel; until then direct and run steps stay blocked. Displacement
is disabled: set_body offset/vx/vy on a translating circle raises before
mutation. Contract section 10a documents S2a and the S3 pending rule.

No reachable path leaves a stale latch (Grok review): initialize and

ClaudeandClaude Opus 5.5 e682d16c3a simulation: derive the stepper latch from moving bodies on add/remove
One helper sets stepper.blocked from _moving_bodies() after add_body,
pre-init remove_body, initialize and stepper recreation, so the latch never
disagrees with motion ownership. Tests: latch follows add/remove; the
after-close assertion checks the actual refusal.

ClaudeandClaude Opus 5.5 b448bc3f71 lbm: guard direct stepper entry while translating circles exist
LBMStepper.step raises before any launch or buffer swap when the owner has
set 'blocked'; Simulation sets it when a translating circle is declared, at
initialize and after stepper recreation. Tests: direct-stepper guard (zero
launches, no swap, unchanged step count), spin/multi-step/checkpoint run
variants, run(0) keeps the pending target, static runs proceed, mixed
moving/static packing parity with the moving id absent, failure refusal of
checkpoint calls, no retry and no re-entry after close.

Adds host tests for set_body routing on real objects, initialize band and
mode rejections before mutation, exclusion from static link packing, and
the Simulation failure lifecycle. Contract status line updated for S1.

ClaudeandClaude Opus 5.5 305ab2409b body: host-only translating-circle state (S1, no kernels)
MovingCircle keeps the applied offset and an optional pending target apart,
validates targets against the applied offset (box, Euclidean 0.5-cell step,
speed, no sliding hold) and commits only after upload, step and sync succeed;
any failure after the upload attempt is fail-closed. Simulation.add_body
(translation=...) declares one; moving circles are excluded from the packed
static links, unsupported modes and swept-band placement are rejected at
initialize, and every positive-step run raises before any device write until
the moving kernels exist. Host tests include a refill-donor enumeration.

ClaudeandClaude Opus 5.5 442979b4db FixedPatchStepper: exchange metadata on the boundary record; _boundaries name
- _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.

The blocked collision had three arms (MRT wrapper, channel SRT, level SRT)

rho/u once and has two compile-time families:
- uniform-equivalent (MRT any level, SRT channel root): collide_dispatch
  arithmetic with zero force, no LES: one clamped omega, collide_mrt_no_force
  or collide_srt with its zero Guo term (unchanged);
- level SRT (BLOCK_ROOT_BC 0/1): unclamped, collide_srt_no_force, shifted
  momentum feq exception kept visible.
No runtime d_params.fx/fy is read. Uniform kernels unchanged (only the
unused inline wrapper is removed from collision_mrt.cuh). Source-text test
updated to the new single call sites.

  link_exchange cut-link oracle, accepted loss);
- test_refinement_gpu: test_bounded_equivalence_and_ownership (dense
  CELERIS_REFINEMENT_AUDIT ownership counters, accepted loss); its physics
  stays in test_bounded_equivalence_blocked; eight_steps loses the audit
  branch and the misleading 'ownership/counts PASS' label;
- test_fine_surface_gpu: test_fine_surface_four_hops (dense per-hop flux
  ledger, CurvedLinkSoA reflection oracle, audit counts: accepted losses;
  raw exchange covers the boundary part only, not full flux closure) and the
  dense SoA fault tests (missing surface buffer, close frees SoA); blocked

New TileContractCPU: level_blocks omitted/None/wrong length/None entry/
wrong arity/non-integer/bool/non-positive/non-tuple/not dividing all raise
before CUDA; whole-level tiles reach CUDA. Rejection tests and fixtures pass

in FixedPatchStepper the dense branches of _build_level/_build_pair/_hop,
_apply_fine_boundary, the fine-level CurvedLinkSoA wiring (_fine_curved,
_fine_flags, _curved, _link_tables, its set_jet_amplitude/initialize/close
paths) and the now-vacuous 'requires all-blocked' guards (shifted,
projected, channel, raw exchange, several L1 rectangles, depth >= 3).

level_blocks is required: one tile (by, bx) of positive integers per level,
else ValueError before any device work naming the whole-level tile
((ny, nx) at the root, the fine window shape for one rectangle) as always
valid. No automatic tile choice. Removed route: None in level_blocks
(dense or mixed dense/blocked storage); parity of D/D, D/B and B/B is
recorded at 1573942 and 2469af7.

Kept: the uniform-grid solver (uniform.cu, Simulation, CurvedLinkSoA,
CurvedBoundaryKernel), FixedPatch2D, pinned historical runners.

ClaudeandClaude Opus 5.5 ce393fa468 test(D1): refinement followup checks run on all-blocked storage
Every FixedPatchStepper in test_refinement_followup passes explicit tiles
(whole-level tiles on the GPU cases, (1, 1) in the pre-CUDA margin
contract). Assertions kept; dense-specific probes rewritten:
- fault fakes use a blocked BlockLayout2D instead of _layouts [None, None];
- slot/reservoir: the fine module sees its tile window incl. halo
  (fx+2, fy+2) with slot fields zeroed; the root's walls are
  block_root_bc 1 (fine 0) instead of dense Y_WALL_BC/TOP_WALL_BC macros;
- raw owner storage is read through each level's layout (to_dense);
- the off-centre allocation bound counts blocked buffers.

ClaudeandClaude Opus 5.5 2469af70d0 test: dense/blocked parity rows for MRT bodies and two fine bodies
Extends DenseBlockedRouteParity (test-only, on 1573942) with the residual
dense-supported combinations named before any dense-route deletion:
- test_mrt_bodies: MRT on a periodic root with a passive circle, an
  actuated circle (+/-) and a velocity Jet with an amplitude switch
  (MRT slot/reservoir is rejected on every route: on_site_velocity is
  SRT-only);
- test_two_bodies: two circles on a wider patch (4, 4, 28, 20), periodic
  and slot/reservoir, Jet on one + passive other, and two actuated (+/-);
  routes D/D, D/B [None, (8, 8)], B/B [(12, 8), (8, 8)].
Same gate: exact FP32 bits and NaN masks at 0, 1, 2, 8 and after
re-initialize; D/B vs B/B raw-exchange ledgers equal for every body.
Docstring table updated; no tolerance, no src change.

ClaudeandClaude Opus 5.5 fd8f1da9f5 examples: fixed-patch circle and jet run on all-blocked storage (M1)
Both public examples move off the dense refinement route, inside the scope
proven by the dense/blocked parity gate (1573942: two-level unshifted SRT,
periodic or slot/reservoir root, one circle/actuation or body-free):
- fixed_patch_jet: LEVEL_BLOCKS = [(12, 8), (8, 8)] (48x48 root, 56x40
  fine window), recorded in its report config;
- fixed_patch_circle: --base-block (default 12 8) and --fine-block
  (default 16 20); the dense 'omit --fine-block' option is gone.
Host test test_example_tiles: each example's tiles (read from the example
source without importing it) build every layout and table up to the first
CUDA call, for the circle in both coarse boundary modes.

ClaudeandClaude Opus 5.5 8db7cee9d5 test: dense/blocked route parity gate and route capability matrix
Test-only, on c6d5dc1. DenseBlockedRouteParity runs the same configuration,
initial state, body/Jet schedule and tilings on D/D [None, None], D/B
[None, FINE_BLOCK] and B/B [(12, 8), FINE_BLOCK], periodic and
slot/reservoir, for body-free, passive circle, actuated circle (+/-) and a
velocity Jet with an amplitude switch: every public and owner array must
match in FP32 bits and NaN masks at steps 0, 1, 2, 8 and after
re-initialize, and the D/B and B/B raw-exchange ledgers (last base step and
last substep) must be equal. No tolerance.

test_route_capability_matrix checks before CUDA what the dense route
rejects (raw exchange on a dense body level, shifted, projected, channel,
several L1 rectangles, depth >= 3 dense). The module docstring holds the
supported/unsupported table and the parked cases (MRT covered elsewhere,
shifted and depth >= 3 have no dense route, several bodies later).

ClaudeandClaude Opus 5.5 19db7d362f refinement: free-memory preflight for every level before any device work
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.

ClaudeandClaude Opus 5.5 8e1feffcad lbm: delete PeriodicBlockStepper; a single blocked level is FixedPatchStepper(refinements=[]) (S2)
The second owner of one blocked level goes. Its capability is the
zero-refinement FixedPatchStepper added in f764d68/985db14 (periodic SRT
level, stationary passive circles, shifted storage, NaN spare, single wait),
which matched it array for array on GPU at 1318fc2 (3 splits x +-circle x
shifted/unshifted) and passes the host lifecycle and fault contracts.

API change for callers:
  PeriodicBlockStepper(cfg, BlockLayout2D.build(ny, nx, by, bx), context=c, objects=o)
  -> FixedPatchStepper(cfg, context=c, refinements=[], level_blocks=[(by, bx)],
                       level_objects=[tuple(o)])
  download() returns a 1-tuple; static-circle tables are
  _level_boundaries[0].tables (was .boundary); no free-memory preflight.

- lbm/block_stepper.py deleted; MAX_GRID_DIM lives in refinement_stepper.
- tests/validation/multigrid/test_block_stepper.py: same frozen GPU gates
  (split identity, FP64 oracle, circle across seams) and pre-CUDA rejection
  cases on the single level; the old-vs-new bitwise test is retired with the
  old class (its result is the 1318fc2 record).
- tests/unit/test_block_step_sync.py folded into test_single_level.py
  (step(n) vs n x step(1) roles and one wait, step(0), mid-batch launch
  failure), which also gains bad-state rejection before upload, download
  failure and activation-failure retry on close.
- test_shifted_storage and test_raw_exchange_gpu use the single level; the
  raw-exchange reference feeds the AMR Jet column and raw ledger through the
  root level boundary instead of patching a private kernel field.
- Pinned historical runners (taylor_green/run_case.py, run_jet_circle_cv.py)
  are unchanged: they only run on trees that still ship PeriodicBlockStepper.
  No alias.

Review follow-ups for S1 (f764d68):
- a single level starts its spare buffer NaN, as PeriodicBlockStepper does,
  so stale halos cannot hide (multilevel initialization unchanged);
- projected explosion is rejected for a single level;
- new tests/unit/test_single_level.py: NaN spare after initialize, per-step
  launch order halo -> BFL (circles only) -> BlockStep with a null kind and
  one wait per step(n), circle solids excluded from the state mask;
- the GPU bitwise comparison also covers shifted storage.

ClaudeandClaude Opus 5.5 f764d68c81 refinement: FixedPatchStepper(refinements=[]) owns a single blocked level (S1)
A zero-refinement FixedPatchStepper is the PeriodicBlockStepper capability:
one doubly periodic blocked SRT level (no LES, Jets or exchange
observation) whose level_objects[0] are stationary passive circles. The
circle tables come from the same checks, now blocks.static_circle_tables
(moved from block_stepper, pycuda-free); BFL, halo and BlockStep launches
are the shared helpers, with an all-ACTIVE (null) kind. Base-level bodies
stay rejected for depth >= 2. PeriodicBlockStepper and its callers are
unchanged (deleted only after S1's GPU result).

Tests: host contract rejections before CUDA for the single level; GPU
bitwise comparison against PeriodicBlockStepper for every split, with and
without the circle (the S2 gate).

Fixes the regressions from the entry/compiler renames (2b3c2a7, d318911)
that Astra reproduced at d318911:
- run_refined_dfg.verify_source: a manifest file missing from the checkout
  is a 'Source mismatch' (was FileNotFoundError); the current-checkout
  (Jet scenario) capture hashes the manifest's harness files plus the
  checkout's own 'git ls-files src', not historical src paths.
- time_window_dfg: candidate file list names kernels/blocked.cu.
- test_projected_pairs: the a135252-only harness's runtime_source is the
  historical receipt value (historical_runtime_source) in the receipt
  fixture and the two mocked run_case.main tests; runtime_source itself
  stays tested against the a135252 package (historical_package).
Harness files, pins, manifests and thresholds are unchanged.

The package already exposed it as CelerisLab.cuda.compiler; the module now

Historical-revision tooling is not edited: the Taylor-Green harness

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

tip, and the kernel-root test first checks the accepted case.

omega/tau check) and each spelled out the raw BlockHaloCopy and
BlockCurvedBoundary argument lists. These now live once in lbm/blocks.py
(level_config, launch_halo_copy, launch_curved_boundary), so a kernel ABI
change has one host site. Both owners keep their own lifecycle; no new

requires build_dir= and load_module requires the PTX path.

Build contract tests use explicit paths; they still check per-build
header/output isolation, interleaved generation, path escapes, refusal of a
removed snapshot, and that a failed compile keeps the previous PTX and
leaves no partial output. No kernel, numerical or launch change.

  loop.
No change to operation order, types, launches or arithmetic.

ClaudeandClaude Opus 5.5 a3df5855a2 kernels (K3): cell kinds in core/, capability guard first, self-contained block collision
- core/cell_kind.cuh holds KIND_ACTIVE/INNER/OUTER (was a constexpr in
  blocks.cu that step/block_channel.cu and the channel_root.cpp shim
  relied on or redefined); blocks.cu, block_channel.cu and the shim now
  include it.
- blocks.cu checks the lattice/model #error guard before the
  BLOCK_ROOT_BC guard and mode includes, so an unsupported build reports
  the real reason first.
- operators/block_collision.cuh includes what it uses (params, macro,
  SRT/MRT collision) instead of relying on blocks.cu's include order.
Preprocessor-only: same kernels, same statements, same arithmetic.

ClaudeandClaude Opus 5.5 1c47cb8570 docs: supported settings review fixes (exact parity test IDs, divisibility guard)
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.

ClaudeandClaude Opus 5.5 ee7074a53d tests: restore the negative checks masked by stale fixtures (WP-B groups B-E)
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.

ClaudeandClaude Opus 5.5 c95a7baae4 test_projected_pairs: regenerate pinned build sources from NUMERICAL_REVISION kernels
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.

ClaudeandClaude Opus 5.5 ec9b3d721c P1 (12/12): one FixedPatchStepper construction and initialize API
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.

ClaudeandClaude Opus 5.5 84b76f49cc P1 (11/n): multipatch GPU/CPU tests use the level-list constructor
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.

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.
