_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.

Rows 2 and ny-3 are ordinary bulk cells that explosion only reads as
donors; only rows 0/1 and ny-2/ny-1 are dropped or reconstructed after
coalescence. Matches the existing y0>=4, y1<=ny-4 slot_reservoir contract.
Adds margin-4 acceptance and margin-3 rejection for a central circle.
One _index helper guards block_cell (block, y, x), slot (block_cell, q)
and map_cut_links (fluid_idx, dir) before addressing; previously e.g.
block_cell(-1, 0, 0) returned -49 and fractional values were truncated.
Adds focused rejection tests and Astra's one-block seam reproducer
(build(4,8,4,8), receiver (2,0), dir 2 -> west-halo slot 90).

Source (write) and reverse-donor addresses are now the receiver's local
core address +/- (ey*local_nx + ex), i.e. the window image the next local
pull reads. block_cell preferred the in-window core image on a one-block
periodic axis, so BFL wrote a copy the pull never reads. Physical
neighbors are still formed only to reject non-periodic exteriors.
block_cell semantics unchanged; docstring notes the image ambiguity.
Adds an end-to-end synthetic seam test (x=0/x=nx-1/corner wraps) on
one-block-x, one-block-y and 1x1 periodic layouts.

Each physical link belongs once to the block owning its fluid receiver
core; the reflected source population is written into that block's own
core/halo copy (no halo copy between BFL and pull). Rejects repeated
links and repeated local writers; one row per link so force counts once.
Documents stale remote solid-core slots vs unique core ownership, and
that the 4-cell refinement halo is separate. Static geometry only.
Tests: address equivalence incl. cross-block q<.5 donors, and static
BFL+pull bit-equal to the dense operator on fluid cells.

- Replace split zero_force_segment / zero_sensor_segment with unified
zero_obs_async() — a single memset covers all three obs segments
(force, torque, sensor), resetting the step accumulator.
- Add _obs_accum_steps counter so read_*(normalize=True) returns the
physically meaningful per-step average for all telemetry fields.
- Sensor now always applies area-normalisation internally; the normalize
parameter only controls the additional time-normalisation step.
- run() gains zero_obs=True parameter (default) to control reset-on-step.
- 7 new integration tests covering accumulation, zeroing, and normalise.
- Fix bug in test_sensor_accuracy.py (undefined loop variable i).
- Bump version to 0.4.0 for the API change.

- Add runtime body topology sync (add_body/remove_body + sync_bodies)
with recompile, DDF patch (feq + BFS inward fill), and commit.
- Unify action/obs flow: set_body/set_force are now host-only;
run() auto-uploads action and downloads obs via CUDA stream.
- Add read_body(id) -> BodyTelemetry and read_bodies() for DRL loops.
- Add FRC_REGION flag (0x0800) for force_region cells.
- Extract equilibrium helpers (lbm/equilibrium.py) and DDF patch module
(body/ddf_patch.py).
- Merge recompile / _runtime_recompile into single _recompile().
- Add n_objects to checkpoint; validate on load.
- Add test suite: 40 unit + 19 integration tests (59 total).
- Add conftest.py and docs/tests_overview.md for test documentation.
- Update README.md and CONFIG.md for new API.
