Horizontal y=56 and vertical x=38 through box 1, normal coordinates
[12.5..26.125] (root128 physical). Nearest-ACTIVE mapping with
deterministic tie rule (distance, finer level, smaller j, smaller i),
duplicate-cell rejection, stored centers and displacements. Replaces my
earlier offsets, which mapped two target pairs to the same U128 cell.
U512 spacing 128/512 and root step r -> U512 step 4r unchanged.
Tests: 24 unique cells per case, nested 3 L0 + 5 L1 + 4 L2 per transect,
U128 max displacement 0.625.

Test-only opt-in. New shear_twin.py: same two L0->L1 boxes as
shear_nested, no L2; leaves [7936,33792], hops [2048,4096], work
154664960. Four fresh cases U128/U256/constant R128 d2/projected R128 d2;
physics is the unchanged depth-2/2N shear_wave.assess. run_case:
--diagnostic twin_shear_n128 with shear_twin.py+shear_nested.py pins, no
snapshot. assess_shear_wave: nested contract made preset-generic (PRESETS)
with nested behaviour unchanged. Labels: twin vs nested = effect of adding
this nested refinement (not abstract depth). shear_wave.py, shear_nested.py
and oracle.py byte-identical.

Cross-platform replay of the frozen assessor returned INVALID_SET because
recomputed eps(128) differed from the Horsea receipt by one ULP. Compare
only that derived float within 4 ULPs (close_ulps); hashes, case identity,
other metadata and scientific thresholds stay exact. Tests accept the
observed one/two-ULP differences and reject 1e-12 relative, 2x, string,
NaN and missing values.

- run_case: --diagnostic scaled_shear_n256 (requires --flow shear_wave;
U256/U512/constant R256/projected R256, Re100, no early trace); N512
only via one of the two scaled diagnostics; scaled_n256 stays TG-only.
- assess_shear_wave: scaled=True contract reusing 92b8afe scaled
case/build/workload checks, shear diagnostic identity; signed rate bias,
refined excess over each control; hash-pinned de5b0cc N128 reference and
descriptive N128->N256 signed trend; CLI --diagnostic/--reference-files.
- tests: scaled contract, set mixing, trend/reference pin, runner options.
- shear_wave.py and oracle.py unchanged.

Bundle celeris-scaled-tg-92b8afe-base-eec4677.bundle (SHA256 9e593384...)
verified with git bundle verify; merged without rewriting history.
Conflicts resolved by retaining both additions: run_case keeps the
shear-wave flow helpers/receipt block and the scaled_n256 diagnostic block,
with scaled_n256 restricted to --flow taylor_green (mutually exclusive with
shear_wave); test_projected_pairs keeps the explicit 'taylor_green'
verify_source argument and 92b8afe's per-scheme selector expectation.

- shear_wave.fit_rate: finite late R=0 returns rate_fit_valid=false with
null fit quantities (no clipping, no invented rate); own screens and
budgets treat it as a failure (CONTROL_SCREEN_FAIL / refined FAIL),
other finite metrics retained, JSON-safe.
- test_projected_pairs: dry-run/execution mocks expect the explicit
'taylor_green' flow argument now passed to verify_source.
- run_case: SHEAR_WAVE_SHA256 repinned; extinction test added.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- shear_wave: validate_rows before screens (exact scheduled steps/t*, no
duplicates, all numeric/list fields finite, nonnegative error fields,
rho_min>0; signed amplitude/phase/interval errors keep their sign);
INVALID_RUN for invalid refined rows; own_screens_pass vs controlled_pass
so a CONTROL_SCREEN_FAIL set never reports a controlled pass; empty or
duplicate refined schemes rejected; pressure-budget redundancy stated.
- run_case: SHEAR_WAVE_SHA256 repinned to the updated module.
- tests: divergence/advection bounds use a(t) and the derived h^2 term;
invalid-row mutations; signed errors allowed; controlled_pass checks.

Modal magnitude R=hypot(a,b) with amplitude error and separate phase;
free-intercept ln R rate fit with per-interval rates, log-fit residual,
t* units and finite-positive check; spurious-pressure naming with raw rms;
INVALID_CONTROL vs CONTROL_SCREEN_FAIL (refined results kept), mixed-source
check, raw ratios to both controls; docs narrow the cubic-term scope,
startup and placement limitations. oracle.py still byte-identical.

Integrate reviewed test changes from 7c1517de819741907fb945ea0ab7864734fa3856 and 340ba4e1dc6386581839c0b28c8fe8a1f4aeb70b unchanged. Document bounded 2D implementation, evidence and open gates; production source and historical manifests are unchanged.
A (per-base read-and-sum per 80-step interval), W (window + step(80) +
one read) and W1 (window + 80 x step(1)) over equal simulated duration
from the same fresh state and warm-up, 3 interleaved repeats. Bitwise
populations and per-interval total impulses (documented engineering
tolerance) are compared outside timing; health checks untimed. Records
candidate source identity (revision, dirty flag, file hashes) and does not
use or modify frozen refined-DFG manifests/results.

Separate GPU class for a shifted MRT, all-blocked, stationary-body case
without Jets: window totals vs summed per-base reads (substep-scaled
tolerance), bitwise populations vs a raw-only stepper, a single step(N)
stepper with bitwise-equal window rows and populations, step(0)
non-change, and reset after a window. SRT/Jet test stays separately
scoped. Test-only.

Scale the window-vs-summed-reads tolerance by the actual absolute fine
substep contributions (last_raw after every fine hop), labelled a
conservative engineering tolerance rather than a proof. Compare
populations by finite FP32 bits plus NaN masks and reject infinities.
Test-only.

FixedPatchStepper(observe_window_exchange=True), which requires
observe_raw_exchange, allocates a second per-link FP64 ledger per body
level. While a window is open, the unchanged BlockAccumulateExchange
kernel also accumulates into it after each fine hop. Small API:
start_exchange_window() zeroes and opens at the current completed step;
read_exchange_window(body_id, level=) is non-destructive and reports
impulse with rates over the integer window duration. initialize/
_initialize_raw and step failure invalidate; remap builds a new instance
with no open window; Jet amplitude updates may stay in-window. Default
disabled: no allocation and no extra launch; last_substep/last_base_step
unchanged. summarize_exchange gains window='window' with duration.
Host contract tests (mocked driver) and a GPU gate against summed
per-base reads with a reordering-bound FP64 tolerance.

Simulation.get_ddf() is flat (9*ny*nx); view it as (Q, cells) before
applying the fluid mask, with a flat-DDF regression. Label A/E as
runner-like force-read workloads (values discarded, no aggregation or
validation; no macro/probe/CSV cost; not benchmark throughput) and split
status lines into CONSTRUCTED and WARM_READY. Test/doc only.

Untimed physical-leaf/fluid health after warm-up and after each timed
window using the existing runner limits (finite macros, rho in [0.5,1.5],
max Mach <= 0.2); refined masks as in run_refined_dfg. Parity comparator
rejects unequal level counts and any infinity; matching NaN stays allowed
only as a storage mask. Regression tests for both. No numerical gate or
production change.

Explicit stream synchronization before/after each timed loop (refined
FixedPatchStepper stream, uniform Simulation stream, in their contexts);
required --max-wall-seconds outer timeout checked between variants and in
per-step loops; untimed finite leaf/fluid health checks; force notes for
B/C/E' (no host reads; final base interval only; whole-window average with
different summation order). Parity stays A/B/C vs A and E/E' vs E only.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Wall-time A/B/C/E/E' variants over equal simulated duration, reusing
run_refined_dfg setup functions. Fresh state and identical warm-up per
repeat, 3 interleaved repeats, construction/JIT, warm-up and bitwise
population/NaN-mask parity checks outside timed regions. B, C and E' are
labelled timing-only (no valid force history). No numerical or
production change.

Remove MRT from the FixedPatch2D rejection matrix (TRT and other
rejections retained); convert host MRT tests to stdlib unittest; add GPU
gates for unshifted dense-vs-blocked MRT two-level roots (exact bits) and
a shifted all-blocked three-level MRT smoke checking per-level omega.
No numerical source change.

Additive compile-time COLLISION_MODEL == 2 branches in BlockStep,
BlockChannelStep and patch_collide repeat the uniform collide_dispatch
MRT sequence (zero forcing, omega clamp, collide_mrt_no_force). SRT
statements, including the shifted retained-delta/direct-momentum path,
are unchanged under the alternate branch. Guards accept SRT or MRT only;
TRT, LES, non-FP32, non-double-buffer and shifted dense/mixed refinement
stay rejected. Transfers, subcycling, BFL, raw ledgers, channel closures,
shifted-Jet SRT guard and PeriodicBlockStepper are untouched. Existing
MRT operator, shifted representation and fixed kinetic rates are reused.

Schedule test drives _pairs[i].explode/coalesce and patches _advance(index,
buffer) for the stale L1->L2 feed mutant; remap rejection test patches
_boundary_hosts entries and hierarchy.pairs instead of the read-only views;
the GPU launch-failure test patches _pairs[0].explode. Assertions unchanged.
