Andrey Filippov authoredRoot cause of the eigen-ON 3x slow pose convergence (probed synthetically): pedestal-included covariance inflates the peak eigen lambdas; sqrt(lambda) reaches imp.eig_max_sqrt (6) where setEigenTransform's k=max(0,1/sqrt(l)-1/6) ZEROES the tile's measurement components - blur-wide tiles (sigma ~2.5-3 px, the lean consolidated-average x center regime) contribute nothing and the solve limps on the few sharp tiles. Companion zero-build retune: raise imp.eig_max_sqrt 6 -> ~20 (dialog) when re-enabling eigen. Solver algebra verified consistent (jt, both Y-Fx variants, WJtJ share the transform).

Per outer cycle: RE-MEASURED pure RMS (prepareLMA, after re-correlation) > MODEL-PREDICTED pure RMS (runLma, after the solve). Jacobian/chain-rule error signature (Andrey's hypothesis): solved_n low but meas_{n+1} bounces back up - the model overpromised and re-correlation takes it back. Healthy damping: meas_{n+1} ~ solved_n, both creep down. Zero extra computation - both values already existed inside IntersceneLma. Co-Authored-By: -

New int knob (0 = quiet): >=2 passes the level into the inner runLma so its existing per-step line prints (good/done flags, full/pure RMS, lambda), with a CuasPoseRT header attributing each block to its scene + outer cycle; 3-4 = the solver's deeper dumps. Shared IntersceneLma untouched. Co-Authored-By: -

Root cause of the 6-13 outer cycles (Andrey's diagnosis, confirmed in code): the inner runLma restarts at ilp.ilma_lambda=0.1 EVERY outer measure<->solve cycle, and the 0.1%-improvement inner exit fires while steps are still lambda-limited -> outer loop under-relaxes (~0.8/cycle decay). New curt.pose_lambda (default 0.001, 0 = legacy ilma_lambda) starts the inner solve near-Gauss-Newton for the near-linear overdetermined 3-angle problem. Trace line now also logs inner runLma iterations per outer cycle + lambda0. 07/12 21:56 run (legacy convergence + uniform MB): dstored RMS az/tilt/roll 0.1416/0.0777/0.0983 vs per-tile-MB baseline 0.1355/0.0765/0.1005 = uniform MB VALIDATED (A1); 0 degenerates; outer cycles mean 7.4, max 13 @ lambda 0.1.

- uniformMotionBlur: representative = defined reference tile nearest the frame center passing getMotionBlur's own gates (mirrored locally; the synthetic averaged frame-center point failed SILENTLY on every scene in the 07/12 run). Degenerate fallback now prints the tried point + rates (self-explaining). - leanFitScene: per-scene 'CuasPoseRT cycles: ... dATR/cycle = ...' trace line (fixed AND legacy modes) - the convergence-trajectory data for the open 'why does azimuth need so many cycles' investigation (3 cycles: az RMS 0.5209; 6 cycles: 0.1805; legacy baseline: 0.1355 px).

Phase A items 1-2 of the pose GPU-migration plan (Andrey's design 07/12/2026): - curt.pose_mb_uniform (default ON): ONE motion-blur vector per scene shared by all tiles - constant-rpm CUAS flow is uniform up to the roll component (small) and wobble (2nd degree). Same Jacobian-times-rates as per-tile getMotionBlur, evaluated at the frame center and broadcast; rates = finite differences of predicted poses, unchanged. OFF = legacy per-tile path (A/B knob). - curt.pose_cycles (default 3): EXACTLY N measure<->solve cycles, no convergence early exit (static GPU launch shape); convergence delta kept as QC printout (flags scenes missing the legacy exit_change_atr). 0 = legacy convergence exit. Validation = pose_test run vs 07/12 JNA baseline (497/497, az/tilt/roll RMS 0.1355/0.0765/0.1005 px) - policy A/B by pose quality, not bit-exactness. Co-Authored-By:

Use the frozen v1 kernel chain in the program instead of the Java CPU code (roadmap step 4, JNA-only per Andrey's 07/12/2026 ruling): - GpuQuad.execConsolidateSensorsTD: base hook, returns false (JCuda backend keeps the CPU bridge - no JCuda launch code for new kernels). - GpuQuadJna override -> TpJna.tp_proc_exec_consolidate: on-device chain, TD never leaves the GPU (zero-copy; only flattened TpTask streams cross); validated bit-exact vs the real-scene avg_td_oob oracle case (tile_processor_gpu jna/test_proc_consolidate, max|diff|=0). - CuasTD.consolidateToSlot0: shared bridge - GPU-first, CPU fallback now OOB-mask-capable (oobSensorMasks + masked consolidateSensorsTD), so both backends produce the v1-filtered average. - CuasPoseRT.leanMeasure + CuasRender.renderSceneVirtual: task sets hoisted out of the MB/no-MB branches and passed to the bridge (replaces the getCltData -> consolidateSensorsTD -> setCltData(0) round-trip). - CuasRtParameters: new curt.oob_soft / curt.oob_hard (defaults = CuasTD.OOB_SOFT/HARD_DEFAULT 12/8, frozen spec; 0/0 = v0 unfiltered A/B knob), new dialog group under CUAS RT; corr-xml keys _curt_oob_*; consumed by the bridge at both call sites and by the avg_td_oob export (replaces hardcoded defaults in CuasRT.kernelTest).

CuasTD.oobSensorMasks() = the contract oracle of the future index_consolidate (pass 1) + OOB priority (pass 2) kernels: input TpTask[2][] (MB pair, [1] may be null = no-MB, matching setInterTasksMotionBlur), sets matched by txy lookup; per tile - present (task!=0) in EVERY provided set, else mask 0; per sensor - depth = min over sets of tile-center distance to nearest frame edge; depth<hard always skipped, any sensor >=soft -> only those, else hard survivors as last resort; NaN xy excluded; margins 0 = tier off (frozen spec soft~12/hard~8 @4e0db8b). consolidateSensorsTD(fclt,counts,masks,colors): mask-gated average, mask 0 = whole-tile NaN poison; null masks = bit-exact v0 (2-arg delegates). AvgTdExport.exportOob(): case carries RAW flattened task streams (exact GPU struct layout, both sets) + margins in manifest + expected masks/ avg/counts. KERNEL_TESTS += avg_td_oob; CuasRT.kernelTest case (set 1 = null until the RT-chain MB wiring).

Replaces the would-be per-kernel checkbox sprawl (Andrey 07/12 design): - CuasRtParameters: KERNEL_TESTS registry {none, avg_td} + kernel_test String param (addChoice, corr-xml _curt_kernel_test, unknown values sanitized to none); one dropdown entry per kernel in the 2c+ ladder. - CuasRT.diagnostics(): kernel_test != none -> EXCLUSIVE kernelTest() dispatch, nothing else runs that pass. - kernelTest() avg_td case = the AvgTdExport call site (settles the open pick): conditioned image_data of the GPU-bound scene -> uniform-grid convert -> CPU oracle + testdata case export (<model>/testdata/avg_td, incl. per-sensor TpTask XY for the OOB soft/hard-margin stage) -> validateConsolidation; imports+compares C++ results/ when present, else prints the exact tests_bin command to run. - CuasMotion.convertFromData: overload with tasks_out (old signature delegates) so the export gets the conversion TpTask grid. mvn -DskipTests clean package: OK.

Per-segment absolute registration of the per-tile terrain models (*_SZXY.tiff: S/Z/X/Y slices) against a 3DEP DEM using the ground_planes geodetic anchor (lat/lon/alt + qenu with the validated axis adapter perm(2,0,1) signs(1,-1,-1)). Reports vertical offset (= IMS altitude error trace; observed -43..+19 m across passes), optional dx/dy/scale search, robust 2x25% trim. Validated on the pond segment 1763233023_625897: placement rms 0.17 m at scale 1.0; scale fitting documented as valid only on temporally stable relief (the 2020-flooded pond trims itself out).

Dense graveyard model triangulated with our poses puts the ground plane at z median -77.5 XML-units vs 77.4 m AGL from ELEV_GND - the earlier 'SfM-scale' caveat was an analysis artifact (wrong sub-camera baseline assumption), retracted. Co-authored-by: -

Exports *-INTERFRAME.corr-xml scene poses as a COLMAP text sparse model (PINHOLE camera, empty points3D) so point_triangulator/OpenMVS can use our IMS/interscene poses with no SfM pose estimation - the FOPEN step-3 path for vegetation scenes where COLMAP's own mapper fails. Convention verified against the 2026-07-10 graveyard run (ref 1763232420_274928): R = diag(1,-1,-1) @ (Ry(az)Rx(tilt)Rz(roll))^T, t = -R C. Fixed-pose triangulation on the corrected NADIR-MERGED-RECTILINEAR renders gives 0.453 px mean reprojection (COLMAP free mapper: 0.351 px on the same images). Co-authored-by:

The RECTILINEAR nadir pass multiplied sampling coordinates by getRByRDist() (distorted->ideal), but sampling positions must be moved to where the ideal ray lands in the distorted image - the FORWARD distortion getRDistByR(), same direction as GeometryCorrection.getImageCoordinates(). The old code ADDED the common radial distortion to the output instead of removing it. Evidence (graveyard ref 1763232420_274928, flat constant-disparity terrain where translation flow must be uniform for a true pinhole image): - plain NADIR-MERGED edge/center flow ratio 0.965 (expected 0.954 from the calibration polynomial: ~4.8 px barrel at the edge), - old RECTILINEAR 0.952 - worse than uncorrected, - COLMAP self-calibrated f=1003/k1=-0.385 on the old rectilinear stack.

Analysis of the -NADIR-SCENE-PXPYD[-NULLCAM] dumps (graveyard ref 1763232420_274928) showed the transformFromVirtual() refinement output is accurate to <0.3 px in the interior, but produces garbage coordinates (5..100 px off) in a rim band at the edge of the valid region, where the interpolation works one-sided over NaN-filled disparity. Rendered, those tiles put wrong content in a border strip: COLMAP fit it as fake barrel distortion (f=1000, k1=-0.38) and image-based rotation measurements were contaminated (apparent ~0.6x roll). A correct scene-frame grid position is the tile center + small ERS displacement, so tiles straying more than 4 px are nulled and render as NaN instead of wrong content, slightly shrinking the usable FOV at the rim.

Second per-scene grid computed with scene_QuadClt=null - the exact camera model used inside Cuas.transformFromVirtual()'s refinement loop. Its non-uniformity isolates the refinement residual; its difference from -NADIR-SCENE-PXPYD isolates the scene-ERS-instance effect. Saved only on the first (non-undistorted) pass. Context: 2026-07-10 analysis of the first -NADIR-SCENE-PXPYD dump showed the sampling grid contains rotation ~0.31x scene roll (R2=0.77) plus correlated scale (~0.955) and shift_y (to -24 px) concentrated in the high-roll-rate half of the graveyard segment - explaining the ~0.6x in-plane content rotation and COLMAP's f=1000/k1=-0.38 self-calibration.

Save the actual scene-frame pXpYD fed to renderGPUFromDSI (after transformToScenePxPyD and optional undistort) as a pX/pY/D hyperstack at tile resolution, one frame per scene, suffix -NADIR-SCENE-PXPYD[-RECTILINEAR]. For offline verification of the nadir render geometry: the grid should be near-uniform (tile centers + ERS displacement); any residual rotation proportional to scene roll would explain the halved in-plane rotation observed in the 2026-07-10 graveyard COLMAP test.

getNadirDisparityMaps() returns pXpYD in the SEGMENT REFERENCE frame (Cuas.transformFromVirtual() output), but renderNadirSequence() passed it to renderGPUFromDSI() with ZERO3 pose and the scene as its own reference, so each scene image was sampled at reference-frame coordinates. Each nadir frame thus carried an extra ref->scene terrain warp: effective camera poses vs the segment reference were ~doubled (ground translation 2x, small rotations ~2x), and the identity transform also canceled ERS compensation. On flat terrain the extra plane homography mimics a valid pose change, so COLMAP converged self-consistently but disagreed with the exported poses (Sim(3)/free monocular scale absorbs the 2x translation; rotations do not scale, explaining the large angular residuals, worst on high-rotation-rate sequences). Now transformToScenePxPyD() maps the reference-frame pXpYD into each scene's own frame (pose + ERS, same machinery as the verified frozen-terrain path) before rendering with ZERO3/self, where the identity pass is an exact pass-through. Output becomes a global-shutter virtual view at each scene's nominal pose. Also converts disparity to the scene frame for 16-sensor parallax compensation, and drops the defensive clone (the transform returns new arrays). Docs updated to state the frame conventions.

Andrey's correction: the eroded average left a wide NaN frame (and all its descendants - EVAL diffs). The average virtual image must be defined wherever ANY scene provides (a single bad first/last row/col at most): combine ALL available contributors, let the count taper naturally near the edges, and reject junk providers per pixel as OUTLIERS vs the MEDIAN with an IQR-based robust sigma (immune to heavy contamination, unlike mean/sigma). Fewer than 4 providers - plain mean; zero - NaN. Geometric erosion (erodeDefined/erodedMasks/AVG_EDGE_ERODE) removed. Next (Andrey): per-TILE outlier rejection in the 16-sensor TD consolidation, anticipating the GPU migration (candidate indicator: CC(0,0) flux, possibly + quadrant energy). Co-Authored-By: -

New evaluation product with the RT render (replaces the manual run-UM-in-ImageJ workflow): merged component only, z = robust all-scenes average + each scene, t ordered for ImageJ auto-range: 1) pixel LoG (the pre-DNN kernel, LINEAR) of the image, 2) LoG of (scene - average), 3) plain (scene - average); t2/t3 are 0 for the average frame. The average is the new robust one (edge-eroded + outlier-rejected), extracted into shared helpers (erodedMasks/robustAverage) used by both saveRenderHyper and the EVAL builder. Co-Authored-By: -

The temporal averages accumulated per-scene edge junk into stable margin artifacts (ROWCOL-04: worst columns x=12,20,28 = 8-px tile pitch - partially covered virtual tiles at the warped-coverage edge; the wobble sweeps which tiles are partial). For the two AVERAGE slices only (individual scenes stay liberal/untouched): each scene's contribution is box-eroded 24 px (3 tile pitches, AVG_EDGE_ERODE - clears the partial-tile ring) and outlier-rejected (3 sigma vs the first-pass mean when >= 4 providers, per Andrey's >1-non-NaN-provider rule); zero eroded providers -> honest NaN.

ROWCOL-04 localization: RT rows regression (18.0 vs 10.6 pre-rework) is CONTENT BIAS, zero in the sky and +10..22 counts in terrain rows - with dense high-contrast content nearly every |UM residual| exceeds max_abs, all pixels get the outlier weight and the weighted mean degenerates to the row's content mean (the small weights cancel), stamping bias bands. lineAverage now zeroes a line's correction when its inlier fraction is below rowcol_min_inlier (default 0.33 - content-dominated lines cannot yield a line-noise measurement) or when |estimate| > max_abs (line noise cannot physically exceed the gate scale). Both guards are no-ops with the gate off (max_abs INF - every pixel is an inlier). Co-Authored-By: -

ROWCOL-03 QC FAIL (rms 52.9 unchanged by erosion) proved the junk edge columns are FULLY covered with DEFINED-BUT-WRONG back-projection values (left-edge convert_direct artifact class) - erosion cannot see them: - exclude a 16px frame-edge band from the content-excluded estimator by geometry (ROWCOL_BP_EDGE_MARGIN); those lines take the legacy fallback; - physical cap in the per-line merge: a content-excluded line value over max_abs cannot be line noise - use legacy (also blunts any future ROWCOL-01-class estimator failure). RT conditioning: profile HPF now applies ONLY when rowcol_um_sigma==0. Stacking it on the UM measurement double-high-passed the row-offset estimate ((1-G10)(1-G8)): removed fraction at period ~20 rows dropped 96% -> 91%, residual mid-band line noise x2 - measured merged RT-RENDER rows metric 10.60 (ROWCOL-02, pre-rework) -> 18.73 (ROWCOL-03). Single sigma-10 high-pass removes strictly more noise at every period than the old sigma-8-only path and protects the LoG band at least as well. Co-Authored-By:

Where a small foreground object (the 3-tile roadside sign, disp ~22) stands in front of a distant background both disparities are legitimate, but for CUAS the background matters: a drone flying exactly behind the sign must stay detectable. conditionDisparityCuas now detects connected clusters of local near-outliers (disparity above the local 7x7 median by curt.disp_fg_over, default 2 px) up to curt.disp_fg_tiles (default 8, 0 = off) tiles and re-fills them with zero-curvature background disparity (TileProcessor.fillNaNs Laplacian relaxation). All three RT call sites (render, pose, appropriation) share the one conditioned source as before. Co-Authored-By: -

1. calculateRowColBackProject: ERODE the coverage mask (blurred mask >= ROWCOL_BP_ERODE=0.95 ~ 16px inside at sigma 10) before the masked UM and averaging - the back-projection is unreliable near its own boundary and boundary garbage dominated the partially-covered EDGE columns in v013-ROWCOL-02 (per-x maxima ~1000 for x<14, interior clean at 13-39 counts). Excluded edge lines drop below MIN_COVER and take the legacy per-line fallback. 2. RT conditioning row/col (problem 2, borrowed from the oracle path, /jp4/ input unchanged): - REORDER: row/col now AFTER photometric+FPN. Measuring on raw captured the FPN's static line structure (rms ~6/12 counts) which the later FPN subtraction removed AGAIN - negative FPN line structure was injected into the output. - UM before averaging (new curt.rowcol_um_sigma, default 10, 0=off): profiles measured on an unsharp-masked copy, subtracted from the original - content no longer biases the averages and the max_abs gate acts on residual counts. - rowcol_max_abs default 50 (calibrated counts; configs saved before this change carry 0 = no gate - set 50 to enable). 3. CuasQC (Andrey's regression-protection design): per-product health statistics with sequence-independent pass bands, appended per run to <center>-QC.json; FAIL prints loudly, never aborts. Increment 1: ROWCOL vectors (rms<=25, scene-max p95<=500 - both of today's defects would have failed) + FPN (rms, row/col line-structure energy), hooked after calculation AND reuse in CorrectionFPN.

The first calculateRowColBackProject mixed two baselines in one image: content-excluded residual (~0, regression baseline) inside the back-projection coverage, full raw-level image-FPN outside it. Whole lines fell outside the max_abs gate and the outlier-weighted average degenerated to the content mean: vectors reached ~2300 counts (legacy ~340) and stamped junk bands at the coverage-window margins into all per-sensor images (v013-ROWCOL-01 MERGED-DBG slices 141/408 etc). Now the two baselines never mix: masked UM (blur(value*mask)/blur(mask)) high-passes the residual within coverage only; NaN-aware line averages use covered pixels only (getLineAvgNaN); lines with under 10% coverage (ROWCOL_BP_MIN_COVER) fall back to the pure legacy UM+gating estimate per line (mergeLineProfiles). Console reports the line-fallback share. Co-Authored-By: -

The registry entry is cleared by submitCurrent() (and again by showDialog()) BEFORE applyCltDialog() runs the getNext*() reads, so getValueOrDefault() - which looked the session up via the registry - always saw null and fell back to every field's default: any value set via POST /mcp/dialog/values was silently lost and OK re-applied the loaded config. The dialog now keeps its OWN session reference for the reads and the await; the registry cleanup clears only its own session (covers the timeout path without clobbering a newer dialog).

CLAUDE: Row/Col correction (RT step 2): curt rowcol_* dialog params + content-excluded noise calculation 2a: CuasConditioning rowcol_* Config now dialog-driven (curt.rowcol_en/ rowcol_hpf/rowcol_hpf_sigma/rowcol_max_abs/rowcol_outlier, "CUAS RT" tab) via CuasConditioning.configFromCurt(); RT Row/Col is optional/bypassable (turn rowcol_en OFF when the FLIR internal correction is verified OK). Defaults reproduce the previous hardcoded Config bit-exactly (rowcol_max_abs 0 = the old INFINITY no-gate). 2b: new CorrectionFPN.calculateRowColBackProject() (gated by NEW imp.cuas_backprop_rowcol, default ON): subtract the back-projected (pose-transformed, photometric-matched) virtual center from each scene BEFORE the UM + line averaging, so bright content no longer biases the row/col averages (the dark horizontal/vertical line artifact). Falls back to (image - FPN) where the back-projection is undefined; serial scene loop (GPU back-projection per scene) - borrowed/non-RT path only. Co-Authored-By: -

CLAUDE: test 7 - windowed-LoG TD product (correlation machinery): broadband exact, crease bands UNCHANGED Andrey's separate-LoG proposal prototyped on the CPU oracle: LoG as a windowed 16x16 DATA tile (taps pre-divided by the sine window AND cosAtten so the effective filter is the exact flux-normalized LoG), full 16-mult quad product per tile (GPU correlateAccumulateTiles table == convolve_tile(conj(data),k) - verified term-by-term), dttt_iie back (mode-TRANSPOSED = GPU dttii_2d), corr_unfold_tile, windowed OLA with sum(w^2) normalization. RESULT: impulse fidelity 2.0e-3 (no aberration-kernel cross-term - a separate pass), but the ramp crease bands are IDENTICAL to the per-bin fold (+/-0.546): the DTT symmetric-extension reflection is only attenuated by the window, not removed - the crease is BASIS-INHERENT to any single-tile TD product. The per-bin fold is the degenerate (symmetric-kernel) case of this same product. Band-free LoG requires pixel-domain convolution on the assembled image. Calibrated conventions along the way (documented in code): correlation product table, dttii mode transpose, corr_unfold patch mapping (+1 offset, no flip), global gain 4.000, window and cos tap precompensation.

Same ramp, same chain: identity 0.000; aberration-like kernel 0.624 counts (band/output 0.18% - present in every render, invisible under content); pure LoG 0.547 (176% of its near-zero output); folded 0.682. The aberration kernels DO band identically in absolute counts - the LoG only unmasks them by removing the content. Corollary: the CURRENT pixel-LoG conditioning also reveals the render's own crease bands (the oracle product bands too, with a different pattern). Co-Authored-By: -

CLAUDE: test 6 - sky-band root cause reproduced: symmetric-extension crease response to LINEAR content Constant -> exactly 0; ramp 5/row -> 8-row-periodic band pattern (0,-0.008,-0.297,-0.547,+0.547,+0.297,+0.008,0) = the LOG-01 run's measured sky bands scaled by the gradient (2.5/row -> -0.14,-0.30,+0.35,+0.16). Pure double CPU chain -> not float32, not GPU, not a kernel coefficient: pixel LoG of a ramp is 0 (odd symmetry) but the per-tile symmetric convolution sees the mirrored extension's slope crease at tile boundaries. Inherent to any per-bin TD multiply (present under aberration kernels too, masked by content - Andrey's LPF-era artifact class, confirmed in substance). Co-Authored-By: -

Andrey's discriminator for the fold-vs-kernel-interaction question: with rend_test + new 'RT render LoG isolation (identity krnl)' ON, saves -CUAS-RT-RENDER-ID (identity kernels: q0=1, q1..3=0, CltExtra=0 - aberration correction AND fractional offsets skipped), -ID-LOG-ORACLE (pixel LoG of -ID), and -LOG-ONLY (pure-LoG kernels, CuasLogFold.uniformKernels(log_td)). If -LOG-ONLY vs -ID-LOG-ORACLE residual persists, the fold/L0 is wrong; if it collapses to the wrap floor, the aberration-kernel interaction is responsible. Refactor: pixel-LoG application extracted to applyPixelLog(); log_test and log_ident share the kernel fetch/restore (finally). Evidence so far (offline, this evening's run): per-sensor high-bin tilt varies s07 +1.3% .. s01 +2.4% with identical scene content => kernel-dependent; per-quadrant deviation maps identical (no single-coefficient signature); kx=0 column regionally incoherent (row-structure channel, separate issue).

t (channels): merged FIRST then s00..s15; z (frames): 'average' (all scenes) + 'average-f:l' (middle-half, renderSceneSequence default range) then scenes - same dimensions as -CUAS-INDIVIDUAL-CUAS-DBG (17 x 499 x H x W) so ImageJ can subtract the stacks directly. NaN-tolerant per-pixel averages. Applies to all three products (RT-RENDER, -LOG-ORACLE, -LOG-FOLDED). Per Andrey 07/06/2026. Co-Authored-By: -

Render loop extracted verbatim into renderPass(), hyperstack save into saveRenderHyper() so both passes share the exact chain.

CLAUDE: CuasLogFold - LoG-into-kernel fold + synthetic impulse/grating self-test (roadmap RT-seed step 1) Findings (all validated to stated precision by the self-test, exit 0): - Per-bin TD quad-multiply == pixel convolution with cos(pi*dx/16)*cos(pi*dy/16) ATTENUATED taps (matches norm_sym_weights in calculateCLTKernel; shift-tap error exactly 1-cos(pi/16) before compensation). getLogTd() therefore pre-compensates LoG taps by 1/cosAtten so the EFFECTIVE filter is the true pixel LoG (machine-exact at non-bin gratings). - Residual floors: symmetric-extension wrap ~0.5-2.5% (inherent to the lapped structure); folded-vs-pixel-LoG A/B cross-term ~7% on a pessimistic spread kernel (test 5 - predicts the full-run A/B floor). - clt_symmetrize_kernel quadrant-3 (AA) sign pattern looks like a latent copy-paste of the AS expression: pure-AA kernel test - math sign 2.6e-3, code sign 1.9e-1. Production kernel files likely carry the wrong AA sign. Co-Authored-By: -

POSE-13 forensics (from files, run 02:18-02:24): the iteration executed but dG came out defined on only 5% of the frame (right-edge strip + terrain patches), so fpn2 = fpn1 over 95% - the ghost survived. Chain: rebuild accumulation was healthy (494/494 scenes, ~75% per scene, ~85% union) but a single-sequence new-average center keeps NaN holes in the weak sky (no parent cumulative, no fillNewGaps), and convert_direct of a NaN-holed center image NaN-poisons nearly all back-projected tiles (task inversion + overlap spread). Fix: composite before the second back-propagation - keep rebuilt values where defined, fall back to the original center in the holes. There dG measures the pass-1 residual (~0), so it degrades to "no correction where not rebuilt" instead of NaN. Adds a coverage printout and a cuas_debug save of the composited center (-FPN-CENTER2-ITERn) so the next run is file-verifiable. Co-Authored-By:
