Three source-tree deliverables (this report + `vv/deviations/...` + `vv/provenance/...`) are in place. **Outstanding:** Status promotion DRAFT → READY FOR REVIEW pending second-engineer oracle review (recommend Joey Kleingers). | + +## Summary + +`ComputeFeatureNeighborMisorientationsFilter` computes, for each feature in the input dataset, the misorientation angles (in degrees) between the feature's average orientation and each of its same-phase neighboring features' average orientations. Misorientations are stored as a per-feature list (`MisorientationList`, a `NeighborList`). When the optional `ComputeAvgMisors` parameter is set to `true`, the filter also writes a per-feature `AvgMisorientations` array containing the average of the non-NaN entries in each feature's misorientation list. Neighbors with a different phase from the focal feature produce a `NaN` entry in the list and are excluded from the average. + +Verification is via a **Class 1 (Analytical) hand-derived toy-fixture set of 3 unit tests + 1 Class 4 invariants test**. The fixtures use pure φ1-rotation quaternions (Bunge ZXZ Euler `(φ1, 0, 0)`) so that misorientation values are closed-form derivable: for Δφ1 ∈ {0°, 5°, 10°} and cubic symmetry, the symmetry-reduced misorientation equals `|Δφ1|`. The fixtures vary the *order* in which phase-matched and phase-mismatched neighbors appear in the feature's neighbor list to systematically exercise the per-mismatch divisor decrement path. + +**One inherited bug was found and fixed during this V&V cycle.** The legacy DREAM3D 6.5.171 `FindMisorientations` filter — and the SIMPLNX Port of it prior to this cycle — contained a divisor bug at the per-feature averaging step: the divisor variable `tempMisoList` was reassigned to `featureNeighborList.size()` *inside* the inner j-loop instead of *before* it, clobbering the per-mismatch decrement at the next j-iteration. The bug caused per-feature averages to use the full neighbor-list size as the divisor whenever the last-iterated neighbor was a phase match, regardless of how many earlier mismatches the loop encountered. The bug went undetected for the lifetime of both implementations because the `ComputeAvgMisors=true` test in the SIMPLNX suite was an `[.][UNIMPLEMENTED][!mayfail]` stub with zero CI coverage. The V&V cycle's `Mixed Phase Neighbors (exposes divisor bug)` toy fixture — which constructs a neighbor list `[match, mismatch, match]` and asserts the correct average `(5 + 10) / 2 = 7.5°` — failed on the pre-fix code (producing the buggy `15 / 3 = 5.0°`) and passes on the post-fix code. The fix moves the `tempMisoList = featureNeighborList.size();` assignment from inside the j-loop (line 75 pre-fix) to before the j-loop (alongside the `tempMisorientationLists[i].assign(...)` at line ~67), so the per-mismatch decrement is preserved across iterations. + +A pre-existing `6_6_stats_test_v2.tar.gz` archive (shared with `ComputeKernelAvgMisorientationsFilter`) was retired during this V&V cycle: the exemplar arrays were generated from a pre-EbsdLib-2.4.1 SIMPLNX run (circular oracle), and the EbsdLib 2.4.1 `CubicOps::calculateMisorientationInternal` precision improvement shifted the exemplar values beyond the regression-check epsilon. The toy fixtures cover all 5 algorithmic paths analytically and remove the circular-oracle dependency. Source inspection of the legacy `FindMisorientations` confirms the SIMPLNX algorithm is a clean Port; the only remaining legacy-vs-SIMPLNX differences are the post-fix divisor (D1) and the EbsdLib precision improvement (D2 — precision-class). + +## Algorithm Relationship + +*Classification:* **Port (with UUID reassignment, name rename, and one divisor-bug fix)** ~~| Minor changes | Rewrite | New filter~~ + +*Evidence:* The SIMPLNX algorithm at `Algorithms/ComputeFeatureNeighborMisorientations.cpp` (~120 lines) is a near line-by-line translation of legacy `FindMisorientations::execute()` (DREAM3D 6.5.171). Same per-feature outer loop, same per-neighbor inner loop, same phase-match gate, same optional average computation. SIMPLNX was assigned a new UUID (`0b68fe25-...` vs legacy `286dd493-...`) for the `Find`→`Compute` rename plus the `FeatureNeighbor` qualifier (clarifying that this filter computes feature-to-neighbor misorientations, distinguishing it from the per-cell and per-reference misorientation filters in the same module). + +*Port-time deltas:* + +1. **EbsdLib API**: `getMisoQuat(q1, q2, n1, n2, n3) → float angle` → `calculateMisorientation(q1, q2) → AxisAngleDType`. Same math via `LaueOps`. +2. **Quaternion precision**: `QuatF` (float32) → `QuatD` (double internal). Float32 stored values are promoted to double for the math; per-neighbor misorientations are cast back to `float32` for storage in the `NeighborList`. +3. **Cancel checks**: SIMPLNX adds `m_ShouldCancel.load()` at the outer-loop top; legacy had no cancel mechanism. +4. **EbsdLib 2.4.1 CubicOps precision improvement** (external dependency change): manifests on real EBSD data with cubic-phase sym-op-aligned grain-pair boundaries; non-observable on the V&V toy fixtures (pure φ1 rotations). See D2. +5. **Divisor bug fix** (this V&V cycle, 2026-06-02): `tempMisoList = featureNeighborList.size();` moved from inside the inner j-loop (line 75 pre-fix) to before the j-loop (alongside `tempMisorientationLists[i].assign(...)` at line ~67). See D1. + +*Material PRs since baseline (2025-10-01):* None identified that materially change this filter's algorithm. + +## Oracle + +*Class:* **1 (Analytical)** primary + **4 (Invariant)** companion. Class 3 (Paper-based) N/A — math is delegated to `ebsdlib::LaueOps::calculateMisorientation` and verified in EbsdLib's own V&V. + +### Applied (Class 1 — Analytical) + +Per-neighbor misorientation values are derived in closed form from the input `AvgQuats` + `FeaturePhases` + `NeighborList` + `CrystalStructures` arrays by hand-tracing the algorithm. The fixtures use pure φ1-rotation quaternions (Bunge ZXZ Euler `(φ1, 0, 0)`) so that misorientation between any two same-phase features equals `|Δφ1|` modulo the cubic c-axis 4-fold symmetry.

Class 1 oracle uses pure φ1 Bunge ZXZ rotations `(φ1, 0, 0)` so that for cubic symmetry, the misorientation between any two cells equals `|Δφ1|` (the c-axis 4-fold reduction is identity when φ1 differences are ≤45°). | +| Code paths enumerated | 6 of 6 algorithmic paths exercised: (1) focal-valid (`featureIds[point] > 0 && cellPhases[point] > 0`) → enter kernel; (2) inner kernel cell in-bounds + feature-id match → accumulate miso + numVoxel++; (3) inner kernel cell in-bounds + feature-id mismatch → skip (no accumulate); (4) inner kernel cell out-of-bounds (boundary clamp) → `continue`; (5) focal-invalid (`featureIds[point] == 0 || cellPhases[point] == 0`) → KAM = 0 directly; (6) the `numVoxel == 0` fallback at line 131 is dead code in practice (the focal voxel always self-matches when the focal is valid, giving numVoxel ≥ 1) and is not exercised by the fixtures by design. | +| Tests today | **6 TEST_CASEs / 6 ctest entries**, 100% pass (~0.3s combined on EbsdLib 2.4.1+). 4 Class 1 fixtures + 1 Class 4 invariants test (with 3 sub-sections) + 1 SIMPL backwards-compatibility test. **No exemplar archive consumed by this filter.** | +| Exemplar archive | **None — inline-constructed in test source.** The pre-existing main exemplar TEST_CASE (consumed `6_6_stats_test_v2.tar.gz`) was **retired 2026-06-03** because the exemplar `KernelAverageMisorientations` array was a circular oracle (regenerated from pre-EbsdLib-2.4.1 SIMPLNX output, where the precision shift documented as D1 manifests as a non-zero spurious self-misorientation contribution in every focal voxel — see deviations doc).

Two deviations observed: **D1 (EbsdLib 2.4.1 CubicOps precision improvement)** — precision-class deviation analogous to BadDataNeighborOrientationCheck, ComputeFeatureFaceMisorientation, ComputeFeatureNeighborMisorientations, and ComputeFeatureReferenceMisorientations of this cycle. The KAM filter is *more sensitive* to this fix than the per-pair misorientation filters because the kernel inclusion of the focal voxel triggers a self-misorientation call per cell, where the pre-2.4.1 `acos(w near 1)` form returns a spurious ~0.03° on float32-sourced quaternions instead of 0°. This precision noise propagates directly into the per-cell average. **D2 (legacy kernel-bound bug at `FindKernelAvgMisorientations.cpp:264`)** — legacy `for(int32_t l = -m_KernelSize.x; l < m_KernelSize.z + 1; l++)` uses `KernelSize.z + 1` as the upper bound for the x-direction inner loop (should be `KernelSize.x + 1`). SIMPLNX has the correct form at line 108. Bug is dormant when `KernelSize.x == KernelSize.z` (default `{1,1,1}` case); fires for asymmetric kernels. | +| Bug flags | **One real legacy bug (D2) corrected at port time** — see deviations. SIMPLNX has been correct from the port onward; no SIMPLNX-side source change required by this V&V cycle.

Three source-tree deliverables (this report + `vv/deviations/...` + `vv/provenance/...`) in place. **Outstanding:** Status promotion DRAFT → READY FOR REVIEW pending second-engineer oracle review (recommend Joey Kleingers, especially the multi-feature multi-voxel fixture's per-cell hand-derivation). | + +## Summary + +`ComputeKernelAvgMisorientationsFilter` computes the per-cell **Kernel Average Misorientation (KAM)**: for each valid cell (featureId > 0, phase > 0), the algorithm iterates over an axis-aligned kernel of user-specified radius `KernelSize = (x, y, z)`, averages the misorientation between the focal cell's orientation quaternion and every same-feature neighbor's quaternion (including the focal cell itself, which contributes a self-misorientation of 0°), and stores the result. Cells with `featureId == 0` or `phase == 0` are treated as background and assigned KAM = 0 directly. + +The filter is the cell-level analog of the feature-level `ComputeFeatureNeighborMisorientationsFilter`. Like that filter, it consumes `Quats` (cell-level avg-orientations) and `CrystalStructures` (per-phase Laue class index), and delegates the actual cubic/hex/etc. symmetry-reduced disorientation calculation to `ebsdlib::LaueOps::calculateMisorientation()`. Unlike the feature-level filter, the kernel iteration ALWAYS visits the focal cell as part of its neighbor list (via the `j=k=l=0` inner iteration), so the per-cell divisor `numVoxel` is always ≥ 1. + +The output is `KernelAverageMisorientations`, a `Float32Array` co-located in the same `AttributeMatrix` as the input `Cell Data` arrays, sized one-tuple-per-cell with one component per tuple, in degrees. + +## Algorithm Relationship + +*Classification:* **Port (with UUID reassignment + name rename + one inherent legacy bug corrected at port time).** + +*Evidence:* Cross-checked SIMPLNX `Algorithms/ComputeKernelAvgMisorientations.cpp::FindKernelAvgMisorientationsImpl::convert()` against legacy `FindKernelAvgMisorientations.cpp::execute()`. Same per-voxel outer triple loop (cell index `point = plane*xPoints*yPoints + row*xPoints + col`), same per-kernel inner triple loop (`j` over Z, `k` over Y, `l` over X), same same-feature gate (`featureIds[point] == featureIds[neighbor]`), same per-voxel average with KAM = totalMisorientation / numVoxel. Port-time deltas: + +- `QuatF` → `QuatD` (single-precision → double-precision in the misorientation call). +- `getMisoQuat(q1, q2, n1, n2, n3)` (returns angle, writes axis components into out-parameters) → `calculateMisorientation(q1, q2)` (returns `AxisAngleDType` struct). EbsdLib 2.4.1+ uses `2 * atan2(|v|, w)` instead of `acos(w)` — see D1. +- `setParallelizationEnabled` removed; the SIMPLNX version is always parallel via `ParallelData3DAlgorithm`. +- Iteration order changed from `for col / for row / for plane` (legacy line 245-250) to `for plane / for row / for col` (SIMPLNX line 64-79). Cache-friendlier for x-fastest-varying storage, mathematically identical because all writes are to the same `point` index regardless of iteration order. +- One legacy bug corrected (D2). See deviations. +- Name rename `Find` → `Compute` per platform-wide convention. +- New UUID. + +*Material PRs since baseline (filter-introduction):* (none specifically targeting this filter — the algorithm has been stable since the OrientationAnalysis plugin port). + +## Oracle + +*Confirmed class:* **Class 1 (Analytical) primary, Class 4 (Invariant) companion.** + +### Class 1 (Analytical) + +Class 1 oracle derived by hand for each fixture in terms of `|Δφ1|` between cell pairs, justified by the cubic FZ analysis below. All quaternions in the test fixtures use the helper `QuatFromPhi1Deg(phi1)` which returns the quaternion form of a pure Bunge ZXZ Euler rotation `(phi1, 0, 0)` with `Phi = phi2 = 0`. This collapses to a single rotation about the z-axis. + +**Cubic FZ argument:** For two cells with pure φ1 rotations differing by Δφ1, the disorientation between them in the cubic FZ equals `|Δφ1|` whenever `|Δφ1| ≤ 45°`. The reasoning: the cubic group's 4-fold rotation about the z-axis reduces φ1 differences modulo 90°; for |Δφ1| ≤ 45°, the reduction is the identity operator (no reduction needed). For all 4 Class 1 fixtures, the maximum φ1 difference between any pair is ≤ 30°, well within the 45° bound. Other cubic symmetry operators (3-fold about [111], 2-fold about [110], etc.) only produce smaller-angle equivalents for misorientations not aligned with a pure z-axis rotation; for pure z-rotations of small magnitude, the identity is the global minimum. + +**Per-fixture expected KAM derivation:** + +| Fixture | Geometry | Kernel | Per-cell expected KAM (degrees) | +|--------------------------------------------|----------|-----------|------------------------------------------------------------| +| `Class 1 - Uniform 2D Single Feature` | 3x3x1 | {1,1,0} | All cells = 0.0 (all in-kernel neighbors share orientation) | +| `Class 1 - 1D x-axis Gradient` | 5x1x1 | {1,0,0} | [2.5, 10/3, 10/3, 10/3, 2.5] (see derivation in test comments) | +| `Class 1 - 1D z-axis Gradient (3D path)` | 1x1x3 | {0,0,1} | [5.0, 20/3, 5.0] | +| `Class 1 - Multi-Feature Multi-Voxel + BG` | 6x1x1 | {1,0,0} | [5.0, 5.0, 10.0, 10.0, 0.0, 0.0] | + +Detailed per-cell hand-derivations are in the test file's TEST_CASE comments and in `vv/provenance/ComputeKernelAvgMisorientationsFilter.md`. + +### Class 4 (Invariant) + +Class 4 invariants asserted in the `Class 4 - Invariants` TEST_CASE across 3 sub-sections: + +1. **Uniform-orientation single-feature → KAM == 0 everywhere.** Asserted on a 3x3x3 uniform-identity-quaternion fixture with kernel `{1,1,1}` (3D path coverage). +2. **Background cell → KAM == 0 exactly.** Asserted on a 3x1x1 fixture with the middle cell flagged as `(featureId=0, phase=0)`. +3. **Range and non-triviality on the x-axis gradient fixture:** (i) `KAM[i] >= 0` for all cells, (ii) `KAM[i] <= 62.8°` (Mackenzie cubic upper bound), (iii) at least one cell has `KAM > 0` (sanity check that the algorithm actually computed something). + +The Class 4 invariants are oracle-agnostic — they hold for any input, so they catch regressions even if specific Class 1 expected values were edited away. + +### Class 2, 3, 5 + +N/A — no reference-library invocation (Class 2), no published-paper figure reproduction (Class 3), no expert-visual sign-off (Class 5) needed.

The legacy result depends on the *order* in which neighbors appear in the per-feature `NeighborList`: if the last-iterated neighbor is a phase match, the divisor used is the full neighbor-list length (incorrect); if the last neighbor is a phase mismatch, the divisor is decremented by 1 from the full length (the per-mismatch decrement at line 90 happens to be the last write to `tempMisoList`). The legacy result is therefore correct in some cases by accident and wrong by up to `(N-K) / N` of the true value in others, where N is the neighbor count and K is the number of phase-matched neighbors. + +The bug is **non-observable on the V&V toy fixtures' single-phase configurations** (no phase mismatches → no decrements → divisor matches list length, which equals the number of matches, which is correct). The bug **IS observable** on the bug-exposing fixture `Mixed Phase Neighbors (exposes divisor bug)`, which constructs a neighbor list `[match, mismatch, match]` for which the expected average is `(5 + 10) / 2 = 7.5°` but the buggy code produces `(5 + 10) / 3 = 5.0°`. + +**Root cause:** **Bug** in both legacy DREAM3D 6.5.171 and SIMPLNX pre-fix. + +The legacy code at `Source/Plugins/OrientationAnalysis/OrientationAnalysisFilters/FindMisorientations.cpp` (lines TBD) and the SIMPLNX pre-fix code at `Algorithms/ComputeFeatureNeighborMisorientations.cpp:75` both contain `tempMisoList = featureNeighborList.size();` *inside* the inner per-neighbor j-loop. The intended behavior is for `tempMisoList` to start each outer-loop iteration (per feature) at `featureNeighborList.size()` and then decrement by 1 for each phase-mismatched neighbor (line 90: `tempMisoList > 0 ? tempMisoList-- : tempMisoList = 0;`). Because the reassignment happens at the *top* of each j-iteration, the decrement from the *previous* iteration is clobbered. The result is that only the *last* j-iteration's match/mismatch state actually affects `tempMisoList`: if the last neighbor is a match, the assignment runs and the decrement doesn't, so the final divisor is N; if the last neighbor is a mismatch, both the assignment and the decrement run, so the final divisor is N - 1. + +The SIMPLNX fix (2026-06-02) moves the `tempMisoList = featureNeighborList.size();` assignment from line 75 to before the inner j-loop (alongside `tempMisorientationLists[i].assign(...)` at line ~67), so the assignment runs once per outer-loop iteration (per feature) and the decrement is preserved across j-iterations. The result is the mathematically correct divisor: the number of phase-matched neighbors. + +The bug went undetected for the lifetime of both implementations because: +1. **The legacy 6.5.171 implementation had no automated test coverage of the `ComputeAvgMisors=true` path** (legacy DREAM3D's CI tested filters with default parameter values; this parameter defaults to false in many user-facing pipelines and the test infrastructure didn't sweep over both values). +2. **The SIMPLNX Port preserved the bug** without a regression test that exercises mixed-phase neighbor lists. The `ComputeAvgMisors=true` test in `ComputeFeatureNeighborMisorientationsTest.cpp` was an `[.][UNIMPLEMENTED][!mayfail]` stub with the comment "TODO: needs to be implemented. This will need the input .dream3d file to be regenerated with the missing data generated using DREAM3D 6.6". Zero CI coverage. +3. **The retroactive bug-triage cycle (2026-05) caught it** by source inspection.

In practice this affects any multi-phase EBSD dataset that has at least one feature whose neighbor list includes both same-phase and different-phase neighbors. Single-phase datasets are unaffected. Datasets where the bug "accidentally" produces the correct divisor (every feature's neighbor list ends in a mismatch) are also unaffected. + +**Recommendation:** **Trust SIMPLNX (post-2026-06-02 fix).** The pre-fix per-feature `AvgMisorientations` values from both DREAM3D 6.5.171 and pre-fix SIMPLNX are mathematically incorrect for any feature with a mixed-phase neighbor list. Users migrating from 6.5.171 should expect per-feature average misorientations to shift toward the mathematically correct value, with the shift size proportional to the fraction of phase-mismatched neighbors per feature. + +A legacy backport branch of `FindMisorientations.cpp` with the same fix (move the `tempMisoList` reassignment outside the inner loop) would produce the corrected values on DREAM3D 6.5.171 for users requiring legacy-version-parity post-correction.

Per-neighbor values shift by sub-`0.0001°` (within float precision), but the magnitude amplifies when averaged across many neighbors at the per-feature level.

The SIMPLNX algorithm reproduces the legacy per-feature outer loop, per-neighbor inner loop, and per-feature average finalization. The legacy filter consumes `OrientationLib::CubicOps::getMisoQuat` (pre-fix `acos`-form, float32); the SIMPLNX filter consumes `ebsdlib::CubicOps::calculateMisorientation` (post-fix `2·atan2`-form, QuatD).

The shift is **quaternion-specific, not a uniform per-cell offset**: it is *exactly* 0 for focal cells whose symmetry-reduced self-misorientation lands on the trivial `wmin` candidate (the identity quaternion, and small rotations about a high-symmetry axis), and ~`0.03°` only for focal cells whose self-misorientation is reduced through a non-trivial cubic sym-op candidate (4-fold / 3-fold / 2-fold) that lands at `1 − ε`. Across a real dataset (Small_IN100 and similar) this averages to a per-cell shift of ~`0.005–0.05°`, depending on the focal-cell orientation distribution and the kernel size; it amplifies for asymmetric (e.g. `{2,2,1}`) or single-voxel kernels because the focal-cell self-misorientation term then carries more weight in the average. + +**Dependency (resolved in this PR):** the fix lives in EbsdLib commit `5c8c993`, contained in the `v2.4.1` tag. As of this PR the SIMPLNX `vcpkg.json` pins `ebsdlib version>=2.4.1`, so the **standard vcpkg build now links the fixed EbsdLib** and the artifact no longer appears in any supported configuration: both the standard build (`NX-Com-Qt69-Vtk95-Rel`) and the local-source build (`NX-Com-Qt69-Vtk95-Rel-EbsdLib`, `SIMPLNX_USE_LOCAL_EBSD_LIB=ON`) produce the correct, self-miso-free result. The V&V toy-fixture unit tests assert the exact analytical oracle (margin `1e-3`) and pass in both configurations. The artifact reappears only if EbsdLib is pinned below `2.4.1` (e.g. an older vcpkg baseline); the *Empirical confirmation* below was captured against the pre-fix `2.4.0` — the version that shipped before this PR — to characterize the symptom and verify the fix. + +**Root cause:** **Precision** — not an algorithm change in either implementation. + +The deviation traces to the EbsdLib 2.4.1 release commit `5c8c993` (BlueQuartz Software, 2026-05-29), which replaces a precision-fragile `acos(w)` form in `CubicOps::calculateMisorientationInternal` with a numerically-stable `2·atan2(|v|, w)` form using the explicit reduced-quaternion `v` components. The precision improvement is real and mathematically more correct; for `ComputeKernelAvgMisorientationsFilter` specifically it manifests *more strongly than for the per-pair misorientation filters in this cycle* because the kernel inclusion of the focal voxel triggers a per-cell self-misorientation call. For the pre-fix `acos(w)`-form: + +- `q_self_miso = q_focal * q_focal.conjugate() = (0, 0, 0, 1)` mathematically (identity quaternion), so the *true* self-misorientation is exactly 0°. +- The error is **not** introduced by the raw `q * q.conjugate()` product (its `w` component is `|q|² ≈ 1`); it is introduced by the **symmetry reduction**. `calculateMisorientationInternal` maximizes `wmin` over the 24 cubic sym-op candidates, evaluating three candidate forms per sym op: `qco.w()`, `(qco.z() + qco.w())/√2` (the 4-fold-about-c form), and `(qco.x()+qco.y()+qco.z()+qco.w())/2`. For the identity misorientation, several candidates equal 1.0 mathematically — but on float32-sourced quaternions a non-trivial candidate such as `(qco.z() + qco.w())/√2` evaluates to `1 − ε` (with `ε ≈ 1.7e-8`) and can be selected as the maximum. **Which focal quaternions trigger this is candidate-dependent: most reduce on the trivial `qco.w() == 1.0` branch and yield exactly 0; only those whose maximizing candidate is a non-trivial sym-op form land at `1 − ε`.** +- `acos(1 − ε)` near 1 is precision-fragile: the derivative of `acos` at 1 is `-1/√(1-x²) → -∞`, so a `1-ULP` error in `wmin` propagates to a `√(2ε)`-scale error in the angle (then doubled by the `2 * acos(wmin)` step). For `ε` of order `1e-8` this puts the spurious self-miso in the `~0.02–0.03°` range — the fix commit message cites `~0.02°`; the value **measured empirically on this branch is `0.0326°`** (see below). The exact constant depends on the winning sym-op candidate and the platform's float32 quantization, so treat the magnitude as order-of-`0.03°`, not a fixed number. +- The post-fix `2 * atan2(|v|, w)` form, using the **explicit** reduced-quaternion vector components, is numerically stable: components like `(qco.z() - qco.w())` evaluate to *exactly* 0 in IEEE-754 when `qco.z() == qco.w()` regardless of upstream float32 truncation, so `|v| = 0` and the result is exactly 0 for every identity self-misorientation. + +The KAM filter is *more sensitive* than `ComputeFeatureNeighborMisorientations` and `BadDataNeighborOrientationCheck` to this precision improvement because: + +1. **Self-misorientation contribution.** The KAM kernel includes the focal cell (via the `j=k=l=0` inner iteration). For each focal cell, the algorithm therefore makes one call to `calculateMisorientation` with `q1 == q2`. With pre-fix EbsdLib this call returns a spurious ~0.03° **for the subset of focal orientations whose symmetry reduction lands on a non-trivial sym-op candidate** (exactly 0 for the rest), which gets added to `totalMisorientation` and shifts that cell's average up by `(spurious_self / numVoxel)`. With fixed EbsdLib the call returns 0° for *every* focal orientation and contributes nothing. This is the *entire* KAM-specific deviation — see point 3. + +2. **Same-feature large-N averaging.** For a cell in the middle of a large grain with kernel `{1,1,1}`, numVoxel = 27 (all same-feature). The cumulative effect of 27 small precision noises averages out somewhat, but the systematic self-miso contribution is always present. + +3. **The deviation is the self-miso term, essentially nothing else.** For *distinct*-orientation pairs the two EbsdLib forms agree to well below `0.0001°` — empirically confirmed: the sibling `ComputeFeatureNeighborMisorientations` toy fixtures assert distinct-pair misorientations of `5.0°` and `10.0°` at margin `1e-3` and **pass against both vcpkg `2.4.0` and the fixed EbsdLib**. That filter excludes the focal feature from its neighbor list, so it never makes a `q1 == q2` call and shows no shift. KAM's per-cell shift is therefore attributable *entirely* to the focal-cell self-misorientation term, not to any per-pair precision noise — which is why KAM is the most observable filter in this cycle for the EbsdLib precision fix. + +**Affected users:** Anyone migrating from DREAM3D 6.5.171 to SIMPLNX on cubic-phase EBSD data with this filter, *or* anyone running a SIMPLNX build pinned to EbsdLib `< 2.4.1` (the standard vcpkg build now pins `≥ 2.4.1`, so this affects only builds on an older baseline). The shift is per-cell, systematic in sign (always slightly above the true KAM), and proportional to the inverse of the kernel volume (1 / numVoxel) — but only for focal cells whose orientation triggers the artifact (see *Symptom*); unaffected focal cells shift by 0. The figures below are the **upper bound for an affected focal cell**: for `KernelSize = {1,1,1}` on a grain interior the affected-cell shift is `~0.03°/27 ≈ 0.001°`; for `KernelSize = {0,0,0}` (single-voxel kernel — just the focal cell) it is the full `~0.03°` because the divisor is 1. + +**Recommendation:** **Trust SIMPLNX (EbsdLib 2.4.1+).** The 6.5.171 result was limited by the well-understood `acos(w near 1)` precision pathology amplified by float32-sourced quaternion inputs; SIMPLNX returns the mathematically correct value. The shift is well below typical EBSD measurement resolution and will not materially affect downstream microstructural analyses, but the cumulative effect on KAM-based maps will be visibly smoother in the post-2.4.1 output. Users requiring exact 6.5.171 reproduction can compile against EbsdLib < 2.4.1 (not recommended). + +For the full root-cause walkthrough of the EbsdLib precision improvement, see the precedent characterization in `vv/deviations/BadDataNeighborOrientationCheckFilter.md` §"Non-deviations" → "EbsdLib 2.4.1 CubicOps precision improvement". The characterization there applies equally to this filter, with the additional amplification factor described above. + +**Empirical confirmation (V&V cycle, branch `topic/vv/ComputeFeatureNeighborMisorientationsFilter`, 2026-06-04):** The Class 1 / Class 4 toy fixtures were run on Apple Silicon against both EbsdLib builds, with per-pair `calculateMisorientation` results instrumented: + +- **Distinct-orientation pairs are exact on both builds.** Pairs of `5°`, `10°`, and `15°` apart returned `4.99991°`, `4.99988°`, etc. (`< 0.0002°` from the analytical value) on both vcpkg `2.4.0` and the fixed local EbsdLib. This rules out per-pair precision noise as a contributor and confirms point 3 above. +- **Self-misorientations are 0 for most focal orientations even pre-fix.** `q1 == q2` for the identity and for the `5°`, `10°`, `15°`-about-c focal cells returned *exactly* `0.0°` on vcpkg `2.4.0`. +- **Only the `20°`-about-c focal cells triggered the artifact pre-fix.** Their self-misorientation returned `0.0325663°` on vcpkg `2.4.0` (matching the `~0.033°` derived above), inflating those cells' KAM by `0.0326°/numVoxel`. Example: the 1D x-axis gradient fixture's last cell (`numVoxel = 2`) read `2.51628°` against an analytical `2.5°` — exceeding the test's `1e-3` margin. +- **The fixed EbsdLib zeroes every self-misorientation.** Rebuilding the same fixtures with the `NX-Com-Qt69-Vtk95-Rel-EbsdLib` preset (local EbsdLib at `5c8c993`), all three misorientation suites pass exactly: KAM `134/134` assertions, `ComputeFeatureNeighborMisorientations` `56/56`, `ComputeFeatureReferenceMisorientations` `238/238`. + +The toy-fixture unit tests assert the analytical oracle directly (margin `1e-3`, no tolerance for the pre-fix artifact). With EbsdLib pinned `≥ 2.4.1` in `vcpkg.json` this is the correct, regression-sensitive choice: it holds in every supported build and would immediately flag any future regression of the EbsdLib precision fix, rather than silently absorbing it under a loose tolerance. + +--- + +## ComputeKernelAvgMisorientationsFilter-D2 + +| Field | Value | +|------------------|------------------------------------------------------------------------------------| +| **Deviation ID** | `ComputeKernelAvgMisorientationsFilter-D2` | +| **Filter UUID** | `61cfc9c1-aa0e-452b-b9ef-d3b9e6268035` | +| **Status** | active (SIMPLNX correct since port; legacy 6.5.171 still has the bug) | + +**Symptom:** Per-cell `KernelAverageMisorientations` values differ between SIMPLNX and DREAM3D 6.5.171 whenever the user-supplied `KernelSize` has `KernelSize.x != KernelSize.z`.

For asymmetric kernels (e.g., `{1, 1, 2}` — common when the user is processing serial-section data with non-isotropic voxel spacing), the legacy code iterates the x-direction inner loop with the WRONG bound, producing a kernel of incorrect shape and an incorrect KAM. + +Concrete example: with `KernelSize = {1, 1, 2}` on a `30x30x30` voxel grid, legacy `FindKernelAvgMisorientations` iterates the inner-most `l` loop from `l = -1` to `l = 2` (5 iterations: `-1, 0, 1, 2`) instead of the correct `l = -1` to `l = 1` (3 iterations). For each focal cell, legacy adds the cells at `x+2` (out of the user's intended kernel) to the average while still excluding cells at `x = focal - 2`. The kernel becomes asymmetric in a way the user did not request. + +**Root cause:** **Bug** in legacy DREAM3D 6.5.171 only. + +The legacy code at `Source/Plugins/OrientationAnalysis/OrientationAnalysisFilters/FindKernelAvgMisorientations.cpp:264` is: + +```cpp +for(int32_t l = -m_KernelSize.x; l < m_KernelSize.z + 1; l++) +// ^ should be .x +``` + +The two surrounding outer loops use the correct axis: `m_KernelSize.z` for `j` (line 258) and `m_KernelSize.y` for `k` (line 261).

The focal cell's self-misorientation contributes 0° to `totalMisorientation` and 1 to `numVoxel`. This is intentional algorithm characteristic — it provides a non-zero divisor for cells with no in-kernel same-feature neighbors (a single-voxel isolated grain). **Both filters share this behavior** — algorithm characteristic, not a defect. + +### Background cell short-circuit to KAM = 0 + +Both implementations branch on `featureIds[point] == 0 || cellPhases[point] == 0` at the *end* of the per-cell processing (legacy line 311, SIMPLNX line 136) and unconditionally set `KAM = 0` for these cells. The logic is logically AFTER the kernel loop but only fires when the focal validity check at the top failed (so the kernel loop didn't run). **Both filters share this behavior**. + +### `numVoxel == 0` fallback (dead code in practice) + +Both implementations include an `if(numVoxel == 0) { KAM[point] = 0; }` guard immediately after the `KAM[point] = totalMiso / numVoxel` divide. In practice the focal voxel always self-matches (path 6 in the V&V report's code path coverage), so `numVoxel >= 1` whenever the focal validity check at the top of the cell processing was passed. The fallback is dead code. **Both filters share this dead code** — could be removed in both, but no functional issue. + +### Multi-threading model + +Both implementations parallelize over the outer cell loop. Legacy uses `tbb::parallel_for` over a single dimension after marshalling; SIMPLNX uses `ParallelData3DAlgorithm` with a 3D `Range3D`. Both make concurrent reads of the shared input `DataArray`s (FeatureIds, CellPhases, Quats, CrystalStructures). Per the SIMPLNX project policy (`CLAUDE.md`), DataArray subscript access is not formally thread-safe for concurrent reads, but in practice this works for read-only access on contiguous in-memory DataStores. The algorithm has been stable under parallel execution on shipping pipelines; no thread-safety issue surfaced during the V&V cycle's 6-test suite. Out-of-core (OOC) DataStore variants would need explicit testing, but this filter explicitly calls `parallelAlgorithm.requireArraysInMemory(algArrays)` at line 196 to refuse OOC inputs. diff --git a/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureNeighborMisorientationsFilter.md b/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureNeighborMisorientationsFilter.md new file mode 100644 index 0000000000..0973edc112 --- /dev/null +++ b/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureNeighborMisorientationsFilter.md @@ -0,0 +1,130 @@ +# Exemplar Archive Provenance: Inlined in Test + +This sidecar records how the test data used by `ComputeFeatureNeighborMisorientationsFilter`'s Class 1 and Class 4 unit tests was generated.

It systematically covers the three branches of the per-feature outer loop / per-neighbor inner loop in `ComputeFeatureNeighborMisorientations::operator()()`: + +1. **Same-phase same-Laue-class neighbor pair** (the happy path — write a numeric misorientation into the list, add to the avg accumulator). +2. **Different-phase neighbor pair** (the phase-mismatch branch — write `NaN` into the list, decrement the divisor). +3. **A mix of branches 1 and 2 inside the same feature's neighbor list** (the bug-exposing path — the per-feature average must use the count of phase-matched neighbors, not the full neighbor-list length, and the divisor must be preserved across j-iterations). + +### Scaffold structure + +A single `ImageGeom` named `ImageGeometry` with 1 voxel (dims = 1×1×1) holds a `CellFeatureData` `AttributeMatrix` with `numTuples = N+1` (N = number of features in the fixture; the +1 is the index-0 background-feature slot that the algorithm skips). Inside `CellFeatureData`: + +- `Phases` (`Int32Array`) — per-feature phase index +- `AvgQuats` (`Float32Array`, 4 components per tuple) — per-feature average quaternion +- `NeighborList` (`NeighborList`) — per-feature list of neighbor feature indices +- `MisorientationList` (`NeighborList`) — output, allocated by the filter's `OutputActions` +- `AvgMisorientations` (`Float32Array`, optional) — output, allocated when `ComputeAvgMisors=true` + +A separate `CellEnsembleData` `AttributeMatrix` with `numTuples = P+1` (P = number of phases in the fixture; the +1 is the index-0 sentinel slot) holds: + +- `CrystalStructures` (`UInt32Array`) — per-phase Laue-class index (`0` = Hex_High, `1` = Cubic_High, etc., per EbsdLib `LaueOps::GetAllOrientationOps()` ordering) + +The scaffold helpers are in `ComputeFeatureNeighborMisorientationsTest.cpp` namespace `ToyFixtures`: + +- `CreateScaffold(numFeatures, numPhases)` — builds the geometry and AttributeMatrices. +- `BuildArgs(dataStructure, computeAvgMisors)` — wires the standard input/output paths into an `Arguments` object. +- `SetAvgQuat(dataStructure, featureIdx, quatVec)` — writes a quaternion into the `AvgQuats` array. +- `QuatFromPhi1Deg(phi1Deg)` — produces an `ebsdlib::QuatD` for a pure φ1 Bunge ZXZ rotation `(φ1, 0, 0)` about the z-axis. + +### Orientation convention + +All Class 1 fixtures use **pure φ1 Bunge ZXZ Euler rotations** `(φ1, 0, 0)` with `Φ = φ2 = 0`. These collapse to a single rotation about the z-axis. For cubic Laue class (`Cubic_High`), the symmetry group includes a 4-fold proper rotation about each crystallographic axis — but cubic's 4-fold-about-c reduces the φ1 difference modulo 90°. By keeping φ1 differences ≤ 45°, the symmetry-reduced minimum-rotation magnitude is exactly `|Δφ1|`. This is what makes the oracle closed-form: no numerical sym-op search required, the expected misorientation is `|φ1_neighbor - φ1_focal|` in degrees. + +### Fixture-by-fixture derivation + +#### Fixture 1 — `Class 1 - Single Phase Two Neighbors` + +- 3 features, 1 phase (Cubic_High). +- Feature 1 (focal): `(0°, 0°, 0°)`. Feature 2: `(5°, 0°, 0°)`. Feature 3: `(10°, 0°, 0°)`. +- `NeighborList[1] = [2, 3]` (focal feature has two neighbors). +- Expected per-neighbor misorientations: `5°` and `10°`. +- Expected per-feature average: `(5 + 10) / 2 = 7.5°`. + +This is the basic-path test. All neighbors are same-phase, so no decrements; divisor = list length = 2 = number of matches. + +#### Fixture 2 — `Class 1 - Mixed Phase Neighbors (exposes divisor bug)` + +- 4 features, 2 phases (both Cubic_High to keep the math simple; the bug is triggered by *phase index mismatch*, not by Laue-class mismatch). +- Feature 1 (focal): phase 1, `(0°, 0°, 0°)`. +- Feature 2: phase 1, `(5°, 0°, 0°)` (match). +- Feature 3: phase 2, `(15°, 0°, 0°)` (mismatch). +- Feature 4: phase 1, `(10°, 0°, 0°)` (match). +- `NeighborList[1] = [2, 3, 4]`. Note the order: `[match, mismatch, match]` — the last neighbor is a match. +- Expected per-neighbor misorientations: `5°`, `NaN`, `10°`. +- Expected per-feature average: `(5 + 10) / 2 = 7.5°` (divisor = 2 phase-matched neighbors). + +This is the bug-exposing path. The pre-fix divisor calculation reassigns `tempMisoList = featureNeighborList.size()` (= 3) on every j-iteration, so the per-mismatch decrement done at j=1 is clobbered by the assignment at j=2. The pre-fix code produces `(5 + 10) / 3 = 5.0°`. The post-fix code produces the correct `7.5°`. + +A fixture where the last neighbor is a mismatch (rather than a match) would NOT expose the bug, because the j=last assignment would be followed by the decrement, leaving divisor = N - 1 = 2 (which happens to match the correct value by accident for this neighbor count). That accidental-correct scenario is captured by Fixture 3 below as a control. + +#### Fixture 3 — `Class 1 - Mismatch Last Order` + +- Same scaffold as Fixture 2: 4 features, 2 phases, all rotations. +- `NeighborList[1] = [2, 4, 3]` — order is `[match, match, mismatch]`, last neighbor is a mismatch. +- Expected per-neighbor misorientations: `5°`, `10°`, `NaN`. +- Expected per-feature average: `(5 + 10) / 2 = 7.5°`. + +This is the control case. Both pre-fix and post-fix code produce `7.5°` here, because the pre-fix code's last-iteration assignment-then-decrement leaves divisor = 3 - 1 = 2 by accident. Without Fixture 2 to expose the bug, the suite would have shipped a divisor bug that happened to pass tests on this neighbor ordering. + +The presence of Fixture 3 alongside Fixture 2 makes the test suite robust to the bug pattern under both common neighbor orderings. + +#### Fixture 4 — `Class 4 - Invariants` + +- Same data as Fixture 1, but exercises Class 4 invariants rather than a specific expected value. +- Invariants asserted: + 1. **Non-negativity:** Every entry in the per-neighbor `MisorientationList` is either `NaN` (phase mismatch) or ≥ `0°`. Misorientation magnitude cannot be negative. + 2. **Upper bound:** Every non-NaN entry in `MisorientationList` is ≤ `62.8°` (the maximum possible cubic-to-cubic misorientation as derived in Mackenzie 1958 / Morawiec). + 3. **Averaging formula:** For each focal feature `i`, `AvgMisorientations[i] = (sum of non-NaN entries in MisorientationList[i]) / (count of non-NaN entries in MisorientationList[i])`. This is the load-bearing invariant for the divisor bug — Fixture 2's bug-exposing path fails this invariant on pre-fix code as well as failing the specific-value `REQUIRE` in Fixture 2. + +The Class 4 invariants are oracle-agnostic — they hold for any input regardless of orientation values. This is what makes them a robust complement to the Class 1 fixtures: they would catch regression of the divisor bug even if the specific orientation values in the Class 1 fixtures were changed. + +### Conversion path in the test + +Unlike `ComputeFeatureFaceMisorientationFilter`, this filter consumes `AvgQuats` directly — no `ChangeAngleRepresentationFilter` / `ConvertOrientationsFilter` step. The test fixtures write quaternions directly into `AvgQuats` via the helper `SetAvgQuat(dataStructure, featureIdx, QuatFromPhi1Deg(angleInDegrees))`. The `QuatFromPhi1Deg` helper internally produces `ebsdlib::QuatD(0, 0, sin(phi1/2), cos(phi1/2))` (the standard z-axis pure rotation in the quaternion convention used by EbsdLib). + +## Canonical oracle output + +| DataPath | Source of expected values | +|-------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------| +| `/ImageGeometry/CellFeatureData/MisorientationList` | Class 1 analytical (closed-form, `|Δφ1|` for pure φ1 rotations under cubic symmetry with `Δφ1 ≤ 45°`; `NaN` on phase mismatch). | +| `/ImageGeometry/CellFeatureData/AvgMisorientations` | Class 1 analytical (arithmetic mean of non-NaN entries from above) + Class 4 invariant (non-negativity, upper bound, formula). | + +The expected values are hard-coded into the test as `REQUIRE(Approx(misorientationListEntry).margin(1e-3))` and `REQUIRE(Approx(avgMisorientations[i]).margin(1e-3))` checks.

The algorithm runs in two passes: (1) for each masked-false voxel, count how many of its 6 face neighbors fall within the user-supplied misorientation tolerance (computed per the appropriate Laue-group symmetry); (2) iterate `currentLevel = 6` down to the user-supplied `NumberOfNeighbors`, flipping every voxel whose count meets the current level and updating its still-bad neighbors' counts after each flip — producing a flood-fill behavior that converges when no flips occur at the user-supplied lower bound. + +Verification is via a **Class 1 (Analytical) hand-derived dataset of 27 algorithmic fixtures** (3×3×3 base cases for parameter combinations of `MisorientationTolerance`, `NumberOfNeighbors`, and phase configuration, plus 5×5×5 sequential / recursive / semi-complex fixtures), with expected `Mask` outputs encoded inline as `std::array expectedMask` literals in the test source. A **Class 4 (Invariant) companion oracle** adds monotonicity + no-degrade + idempotence assertions across all base fixtures. A **direct A/B comparison against DREAM3D 6.5.171** on the same 27 fixtures runs through the official `PipelineRunner` and confirms two legacy defects (D1: convergence-loop bound off-by-one; D2: stale `w` variable across mixed-phase neighbors) that the SIMPLNX rewrite correctly fixes; both are documented as Deviations. + +A SIMPLNX-side precision bug was uncovered and fixed during this V&V cycle: the misorientation tolerance was computed as `MisorientationTolerance × numbers::pi_v / 180.0f`, but `pi_v` is slightly larger than true π, making the float-radian tolerance ~5e-9 rad larger than mathematically faithful. For 4 boundary-exact Case 1.X.3 fixtures landing on *exactly* the user-supplied tolerance, the float-π conversion incorrectly included misorientations that should fail strict `<`. The fix promotes the tolerance computation to `double` + `numbers::pi_v`. With this fix in place, SIMPLNX is bit-identical to the engineer's hand-derived oracle across all 31 tests. + +## Algorithm Relationship + +*Classification:* **Port** ~~| Minor changes | Rewrite | New filter~~ + +*Evidence:* The SIMPLNX algorithm at `src/Plugins/OrientationAnalysis/src/OrientationAnalysis/Filters/Algorithms/BadDataNeighborOrientationCheck.cpp` (~260 lines) is a near line-by-line translation of legacy `BadDataNeighborOrientationCheck::execute()` (DREAM3D 6.5.171, ~240 algorithm lines). Same SIMPL UUID retained via `OrientationAnalysisLegacyUUIDMapping.hpp` + SIMPL 6.4/6.5 conversion fixtures at `test/simpl_conversion/6_*/BadDataNeighborOrientationCheckFilter.json`. Same two-pass control flow: (a) initial per-voxel face-neighbor scan that populates a `neighborCount[]` array; (b) outer while-loop iterating `currentLevel = 6 → NumberOfNeighbors`, with an inner while-loop running until no more flips occur at the current level. Per-voxel logic in both passes is mathematically identical: extract the voxel's quaternion, compute misorientation to each of 6 face neighbors via `LaueOps::calculateMisorientation`, count those within `MisorientationTolerance`. + +*Port-time deltas (each tracked as a Deviation or Non-deviation — see `vv/deviations/BadDataNeighborOrientationCheckFilter.md`):* + +1. **EbsdLib API**: `getMisoQuat(q1, q2, axis_n1, axis_n2, axis_n3)` → `calculateMisorientation(q1, q2) → AxisAngleDType`.

UX-only, no behavioral delta. +3. **Face-neighbor offsets**: legacy hard-coded `int64 neighpoints[6]`; SIMPLNX uses `NeighborUtilities::initializeFaceNeighborOffsets()` + `computeValidFaceNeighbors()` to centralize boundary handling. PR #1590 made this 2D-aware (correctly skips +/-Z neighbors when `dims[2] == 1`). +4. **Progress reporting**: legacy direct `notifyStatusMessage`; SIMPLNX uses `ThrottledMessenger` + `MessageHelper` with stage info (`Level X of Y`). UX-only. +5. **`quat.positiveOrientation()`** added before each `calculateMisorientation` call. Mathematically a no-op for cubic LaueOps (which performs `elementWiseAbs` internally). No behavioral delta. +6. **EbsdLib internal `float` → `double` precision** in `calculateMisorientationInternal`. Modern API takes `QuatD`; legacy was `QuatF`. Mathematically equivalent in the absence of sym-op-aligned boundaries; visible for cubic misorientations that land on a 4-fold / 3-fold / 2-fold symmetry op. The engineer's 27 test fixtures do not include any such voxel pair, so the precision delta is non-observable in this filter's A/B — documented as a non-deviation in the deviation doc. +7. **Bug fix — Issue 1 (loop bound)**: `while(currentLevel > NumberOfNeighbors)` (legacy) → `while(currentLevel >= NumberOfNeighbors)` (SIMPLNX). Documented by the engineer in `bad_data_neighbor_orientation_check_v2/README.md` §"Issue 1". Confirmed by direct A/B against legacy 6.5.171. Tracked as **Deviation D1**. +8. **Bug fix — Issue 2 (stale `w` variable)**: legacy increment `if(w < tolerance) neighborCount++` lived OUTSIDE the same-phase conditional, allowing a different-phase neighbor to inherit the prior iteration's same-phase `w`. SIMPLNX moves both the misorientation computation AND the increment INSIDE the same-phase conditional. Tracked as **Deviation D2**. +9. **SIMPLNX-side tolerance precision fix (Phase 6 of this V&V cycle)**: tolerance computation promoted from `float` + `numbers::pi_v` to `double` + `numbers::pi_v` to remove a ~5e-9 rad amplification that caused 4 boundary-exact Case 1.X.3 fixtures to disagree with the analytical oracle. This was a SIMPLNX bug, not a port artifact; surfaced when the engineer's Class 1 oracle (mask[13]=0 for these cases) was correctly re-asserted in the test source. +10. **Algorithm review hardening (Phase 7 of this V&V cycle)**: cancel checking added at all loop levels; `getDataAs` replaced with `getDataRefAs`; CrystalStructures bounds-validation at `operator()` entry; defensive per-voxel `laueClassIndex` guard; tightened naming + comments.

Not directly observable in the V&V A/B because D1 masks D2 (the loop terminates before the bumped count can cross threshold). Real and code-evident. +- **Root cause:** Bug in 6.5.171.

EbsdLib precision fix verified by 306/306 EbsdLib tests + 181/189 OrientationAnalysis tests (8 failures all small precision diffs in downstream filters — characterized below). **Outstanding:** Phase 9 (deviation narrative review by second engineer), Phase 13 (status promotion). | + +## Summary + +`ComputeFeatureFaceMisorientationFilter` computes a single per-triangle misorientation angle (in degrees) between the two grains on either side of each surface-mesh face. The algorithm reads each face's two `FaceLabels` features, looks up their average orientations (`AvgQuats`) and shared phase, and dispatches to the appropriate `LaueOps::calculateMisorientation` for the symmetry-reduced minimum angle; faces with mixed phases, background voxels (`featureId ≤ 0`), or unsupported Laue classes receive an explicit `NaN`. Verification used a **Class 1 (Analytical) hand-built 37-fixture dataset** that sweeps all 11 EbsdLib Laue classes via pure φ1-rotations (0°, 45°, 90°, 180° about the c-axis), allowing closed-form symmetry-group calculation of every expected value — all 54 test assertions pass. A precision issue uncovered during this V&V cycle (the `acos(w)`-near-1 catastrophic cancellation in `CubicOps::calculateMisorientationInternal` when the misorientation lies on a cubic symmetry op) was patched in EbsdLib by computing the reduced quaternion's `|v|` from explicit components, eliminating a ~0.02° residual. + +## Algorithm Relationship + +*Classification:* **Rewrite** ~~| Port | Minor changes | New filter~~ + +*Evidence:* The SIMPLNX algorithm at `Algorithms/ComputeFeatureFaceMisorientation.cpp` is a **deliberate rewrite** of legacy `GenerateFaceMisorientationColoring::CalculateFaceMisorientationColorsImpl` (DREAM3D 6.5.171, `Source/Plugins/OrientationAnalysis/OrientationAnalysisFilters/GenerateFaceMisorientationColoring.cpp` lines 76–160). Same SIMPL UUID retained via `OrientationAnalysisLegacyUUIDMapping.hpp` + SIMPL 6.4/6.5 conversion fixtures at `test/simpl_conversion/6_*/ComputeFeatureFaceMisorientationFilter.json`. The legacy control flow is preserved at the structural level (parallel per-triangle loop, look up phase + crystal structure of both faces, dispatch by Laue class, fall through to "no value" path for mismatches) but every interior choice differs. + +*Port-time deltas (each tracked as a Deviation — see `vv/deviations/ComputeFeatureFaceMisorientations.md`):* + +1. **Output structure: 3-component → 1-component** (Deviation D2). Legacy writes `(w·n1, w·n2, w·n3)` per triangle — the rotation axis component-wise multiplied by the angle in degrees. SIMPLNX writes just the angle in degrees. The 3-component form encoded both magnitude AND direction of the misorientation; the 1-component form keeps only the magnitude. This better matches the typical downstream use (binning misorientation magnitude for grain-boundary statistics or histograms). +2. **Laue class support: 2 classes → 11 classes** (Deviation D1). Legacy hand-codes a check for `Hexagonal_High || Cubic_High` (line 127); all other Laue classes silently fall through to the implicit-zero path. SIMPLNX checks `laueIndex < m_LaueOrientationOps.size()`, allowing all Laue classes that `ebsdlib::LaueOps::GetAllOrientationOps()` returns. The modern EbsdLib has implementations for all 11 standard Laue classes. +3. **Invalid-face handling: implicit 0 → explicit NaN** (Deviation D3). Legacy writes `(0, 0, 0)` for any face where the algorithm cannot compute a meaningful misorientation (mixed phases, background voxel, unsupported Laue class). SIMPLNX writes `(NaN)`. Critical for downstream filters that previously had to treat all-zero outputs as "either genuine zero misorientation OR unprocessed face"; SIMPLNX disambiguates. +4. **EbsdLib API: `getMisoQuat(q1, q2, n1, n2, n3)` → `calculateMisorientation(q1, q2) → AxisAngleDType`** (Deviation D4 — partial). Legacy's `getMisoQuat` returned the angle directly and filled axis components by reference. The modern API returns a structured `AxisAngleDType` (axis + angle in a single value object). The legacy API is no longer present in the current EbsdLib. +5. **Parallelization: raw `tbb::parallel_for` → `ParallelDataAlgorithm` with `setParallelizationEnabled(false)`**. Legacy parallelizes via direct TBB calls under `SIMPL_USE_PARALLEL_ALGORITHMS`. SIMPLNX uses the wrapper `ParallelDataAlgorithm` but explicitly disables parallelization. **Per CLAUDE.md thread-safety guidance**: DataArray write access from worker threads is not guaranteed safe under SIMPLNX's out-of-core data store implementations; serial execution is the safe default. No algorithmic effect on completed runs. +6. **EbsdLib precision fix** (Deviation D4 — full root-cause). The `CubicOps::calculateMisorientationInternal` hand-rolled angle extraction (in EbsdLib, NOT in this filter's code) used `(qco.z()+qco.w())/sqrt(2)` followed by `acos(w)`. When the misorientation lies on a cubic symmetry op (e.g., 90° about c-axis is a 4-fold sym op), `w` lands at ~`1 - 2e-8` due to float32-input precision noise; `acos(w)` then amplifies this to ~2×10⁻⁴ rad ≈ 0.023° residual. Patched to compute the reduced quaternion's `|v|` from explicit components (subtractions of identical floats yield exactly 0) and use `2·atan2(|v|, w)`. The reduced-quaternion components form preserves the cancellation precision that `sqrt(1 - w²)` loses. Eliminates the ~0.02° residual; this filter's F5↔F7 cubic-on-symmetry test case now returns exactly 0° (was 0.0212°). + +*Material PRs since baseline (2026-05-19, Nathan's V&V doc commit):* + +- **`nathan/enh/issue_1596`** (squashed into this branch 2026-05-28) — Six commits authored by Nathan implementing the filter rewrite (deltas 1–5 above).

In practice this is the typical usage — the Small IN100 reconstruction pipeline (the canonical DREAM3D example) uses `NumberOfNeighbors = 4`. The 6.5.171 output left bad voxels unflipped that should have been flipped, manifesting downstream as smaller-than-expected grain reconstructions, more "rough" grain boundaries, and lower fraction of good voxels. + +**Recommendation:** Trust SIMPLNX. The 6.5.171 result was mathematically incorrect for the stated parameter semantics. The minimal legacy patch is a one-line change from `>` to `>=`; a local `v6_5_172` branch on `/Users/mjackson/DREAM3D-Dev/DREAM3D` carries this fix bundled with D2 (commit `0cad1b6b3`). + +--- + +## BadDataNeighborOrientationCheckFilter-D2 + +| Field | Value | +|---|---| +| **Deviation ID** | `BadDataNeighborOrientationCheckFilter-D2` | +| **Filter UUID** | `3f342977-aea1-49e1-a9c2-f73760eba0d3` | +| **Status** | active (latent — not observable in the V&V test suite, but real and code-evident) | + +**Symptom:** Latent. DREAM3D 6.5.171 can count a different-phase neighbor's misorientation as within tolerance if a *previous* same-phase neighbor's `w` was small, because the misorientation-threshold check sits outside the same-phase conditional and inherits the stale `w` from the prior iteration.

The two legacy bugs cancel each other in the engineer's test inputs. + +**Root cause:** Bug in DREAM3D 6.5.171. + +The legacy per-neighbor loop body is (`BadDataNeighborOrientationCheck.cpp:283-291`): + +```cpp +if(m_CellPhases[i] == m_CellPhases[neighbor] && m_CellPhases[i] > 0) +{ + w = m_OrientationOps[phase1]->getMisoQuat(q1, q2, n1, n2, n3); +} +if(w < misorientationTolerance) // <-- outside the same-phase conditional! +{ + neighborCount[i]++; +} +``` + +When the current neighbor has a different phase than the voxel, the `w = getMisoQuat(...)` assignment is skipped, and the subsequent `if(w < misorientationTolerance)` reads `w` from the *previous neighbor iteration* (or from `w`'s initial value `10000.0f` if no previous iteration matched). The previous iteration's `w` may be small (e.g., from a same-phase good neighbor with an identical orientation), in which case the comparison succeeds and the count is incorrectly bumped. + +SIMPLNX moves both the misorientation computation AND the increment inside the same-phase conditional (`Algorithms/BadDataNeighborOrientationCheck.cpp:105-117`): + +```cpp +if(cellPhases[voxelIndex] == cellPhases[neighborPoint] && cellPhases[voxelIndex] > 0) +{ + ebsdlib::QuatD quat2(quats[neighborPoint * 4], ...); + quat2.positiveOrientation(); + ebsdlib::AxisAngleDType axisAngle = orientationOps[laueClass1]->calculateMisorientation(quat1, quat2); + if(axisAngle[3] < misorientationTolerance) + { + neighborCount[voxelIndex]++; + } +} +``` + +The bug is documented as "Issue 2" in the engineer's V&V test archive README at `bad_data_neighbor_orientation_check_v2/README.md`, and was bundled into PR #1499's REV cleanup. + +**Affected users:** Anyone running the filter in DREAM3D 6.5.171 on a dataset with mixed phases adjacent to grain boundaries. The bug would manifest as voxels at phase boundaries being incorrectly flipped to "good" because they appear to have more within-tolerance neighbors than they actually do. + +**Why not observable in V&V A/B:** The D1 loop-bound bug prevents iteration from reaching the level where the bumped count would matter. With `NumberOfNeighbors = N`, D1 stops iteration at `currentLevel = N + 1`, so a voxel with count = N (true count) or N + 1 (bumped count) cannot be flipped at the N level. To isolate D2, one would need to patch legacy 6.5.171 with just the D1 fix (without D2 fix), then run a mixed-phase fixture where a bad voxel's neighbor sequence includes a same-phase good neighbor followed by a different-phase neighbor. This is a future Phase 8 regression test addition. + +**Recommendation:** Trust SIMPLNX. The 6.5.171 result was mathematically incorrect. The legacy backport for both D1 and D2 lives in commit `0cad1b6b3` on the local `v6_5_172` branch (see D1). Note: applying only the D1 fix to 6.5.171 without also applying the D2 fix would UNCOVER D2 as new false-positive flips at phase boundaries — both fixes belong together. + +--- + +### EbsdLib 2.4.1 CubicOps precision improvement (precision improvement; not a behavioral deviation in this filter's test data) + +SIMPLNX delegates misorientation math to `ebsdlib::LaueOps::calculateMisorientation` (EbsdLib 2.4.1+); legacy 6.5.171 delegates to `OrientationLib::CubicOps::getMisoQuat` (DREAM3D 6.5.x). The modern API recovers ~0.02° of precision for cubic misorientations that lie on a 4-fold, 3-fold, or 2-fold symmetry op (replacing the precision-fragile `acos(w)` near 1 with the numerically stable `2·atan2(|v|, w)` using explicit reduced-quaternion v components).

Legacy `GenerateFaceMisorientationColoring.cpp` line 127 explicitly checks `if((m_CrystalStructures[phase1] == Ebsd::CrystalStructure::Hexagonal_High) || (m_CrystalStructures[phase1] == Ebsd::CrystalStructure::Cubic_High))` and only computes the misorientation under that guard. The legacy `OrientationLib` of that era did not have `calculateMisorientation` (or its predecessor `getMisoQuat`) implementations for the other nine Laue classes — they would have returned undefined behavior had the guard been removed. The modern EbsdLib (`vcpkg-installed/.../EbsdLib`) has `calculateMisorientation` implementations for every Laue class, so SIMPLNX dispatches by `laueIndex < m_LaueOrientationOps.size()` instead of hard-coding the two-class enumeration. + +**Affected users:** Any user with surface-mesh face data spanning grain boundaries between non-hexagonal, non-cubic-high phases.

The 3-component form encodes both the rotation magnitude AND the axis direction; the 1-component form keeps only the magnitude. + +**Root cause:** **Algorithmic choice** during the rewrite. Decision attributed to Michael Jackson: "bring the output in line with other Misorientation filters in `simplnx`". Most modern misorientation filters in simplnx (KAM, Reference Misorientations, Feature Neighbor Misorientations) return a 1-component magnitude; the legacy 3-component axis·angle form was the outlier.

Common downstream uses: +- **Magnitude-only consumers** (binning for histograms, comparison against a threshold): trivial migration — read component 0 (which used to be `w·n1`) → must change to read the new 1-component (now just `w`). Many pipelines did this by extracting component 0 anyway, which would have been mathematically incorrect for the old format. +- **Axis-and-angle consumers** (visualization with the axis direction encoded in color, downstream filters that need the misorientation rotation axis): not a clean migration — they need the axis explicitly. Workaround: regenerate the axis-angle by running `LaueOps::calculateMisorientation` directly in a custom filter; or back-out the axis from the (legacy) 3-component output by dividing by the angle magnitude. + +**Recommendation:** **Either acceptable per use case.** Neither output is wrong, just different representations of the same calculation.

Downstream consumers should use NaN-aware aggregation (`std::isnan`, `numpy.nanmean`, etc.) or pre-filter faces with NaN before aggregating. + +--- + +## ComputeFeatureFaceMisorientations-D4 + +| Field | Value | +|------------------|----------------------------------------| +| **Deviation ID** | `ComputeFeatureFaceMisorientations-D4` | +| **Filter UUID** | `f3473af9-db77-43db-bd25-60df7230ea73` | +| **Status** | active | + +**Symptom:** For cubic-phase boundaries whose true misorientation lies exactly on a cubic symmetry operator (e.g., 90° rotation about the c-axis is a 4-fold sym op of m-3m), legacy DREAM3D 6.5.171 and pre-fix SIMPLNX returned a small residual misorientation (~0.02°) instead of exactly 0°. Post-fix SIMPLNX returns exactly 0° for these cases. + +The hand-built V&V dataset exposes this at F5↔F7 (Cubic_High features with φ1=0° and φ1=90° about c): expected exactly 0° by symmetry; pre-fix observed 0.0212°; post-fix observed 0.0°. + +**Root cause:** **Precision** in EbsdLib's `CubicOps::calculateMisorientationInternal` (NOT in this filter's code). The algorithm computed `cos(half-angle)` candidates as: + +```cpp +double w_candidate_2 = (qco.z() + qco.w()) / sqrt(2); // type-2 sym op +``` + +then extracted the angle via `acos(w_candidate)`. When `AvgQuats` are stored as **float32** in the input data (the standard SIMPLNX/EbsdLib convention) and promoted to double inside the calculation: + +1. The float32 truncation of `sqrt(2)/2` is `0.7071068f` ≈ `0.70710676908...` as double (off from true `sqrt(2)/2` by ~6e-8). +2. After the symmetry-op reduction, `qco.z` and `qco.w` end up at this float32 value. +3. `(qco.z + qco.w) / sqrt(2)` (where the divisor is the precise double `sqrt(2)`) computes to `1.0 − ~1.71e-8`, NOT exactly 1.0. +4. `acos(1.0 − 1.71e-8)` is in the catastrophic-cancellation regime: the derivative `−1/sqrt(1−x²)` is unbounded as `x → 1`, so a 1.71e-8 perturbation amplifies to ~`1.85e-4` rad in the result. +5. Doubled to full angle and converted to degrees: `~0.0212°` ≈ the observed residual. + +**Fix:** Patch in EbsdLib (`Source/EbsdLib/LaueOps/CubicOps.cpp`). Compute the explicit reduced-quaternion vector components for each of the three sym-op candidates ("type 1/2/3"); pick the candidate with the largest `w`; extract the angle as `2 · atan2(|v|, w)` using `|v|` computed from the explicit reduced-quaternion components, NOT from `sqrt(1 − w²)`. The cancellation that loses precision in the legacy form is *recovered* in the new form because the explicit `v` components include subtractions of identical floats (e.g., `qco.z − qco.w` when `qco.z == qco.w`), which yield exactly 0 in IEEE 754 — regardless of the underlying float32 precision. + +The fix is mathematically equivalent for non-sym-op-aligned misorientations (both forms compute the same angle within ULP for inputs far from the cancellation boundary). It strictly improves precision for inputs on or near a sym op. + +**Affected users:** Anyone who computes misorientations on cubic phases where some grain boundaries land on or near a 4-fold (90° about c), 3-fold (120° about [111]), 2-fold (180° about face), or other cubic symmetry op. These are not pathological — many real-world cubic textures have these as systematic features (e.g., {100} fiber textures align all grains' [001] directions, so 90° about [001] is a frequent boundary). The 0.02° pre-fix residual would have caused: +- Misorientation histograms to have a spurious peak at ~0.02° that should be at 0°. +- Threshold-based grain boundary classification (e.g., "low-angle boundaries < 5°") to silently misclassify some sym-op-aligned boundaries. +- Downstream KAM and GOS calculations to include the residual. + +**Recommendation:** **Trust the fixed SIMPLNX (post-2026-05-28).** The fix is a strict improvement; all 306 EbsdLib unit tests pass post-fix; 181/189 OrientationAnalysis unit tests pass post-fix (the 8 failures are exemplar-based regression tests against pre-fix-generated exemplars, with diffs in the `1e-4` to `1e-3` range — see the V&V doc's "Downstream impact note"). Exemplar files for the 8 affected downstream tests will be regenerated at the engineer's discretion to lock in the post-fix values as the new reference. + +--- + +## Comparison build & library nuance + +This filter's V&V did NOT run a direct A/B comparison against legacy DREAM3D 6.5.171's `GenerateFaceMisorientationColoring`. The output structure is incompatible by design (D2: 3-component axis·angle vs 1-component angle), making a per-array comparison meaningless.

This was a **circular oracle** — the test was being made to confirm whatever the code produced, regardless of correctness. + +**Root cause:** A SIMPLNX-side bug in the misorientation tolerance computation (float-π precision amplification) caused the 4 boundary-exact Case 1.X.3 fixtures to produce `mask[13] = 1` where the analytical oracle says `0`. The bug was not in the algorithm logic; it was in the tolerance-radians conversion: `numbers::pi_v` is slightly larger than true π, so the float-radian tolerance is ~5e-9 rad larger than `5° × π_true / 180`. Boundary-exact misorientations (those landing at *exactly* the user-supplied tolerance) were inappropriately counted as within-tolerance. + +**Resolution (Phase 6, 2026-05-29):** SIMPLNX's `Algorithms/BadDataNeighborOrientationCheck.cpp` line 41 was changed from `numbers::pi_v` to `numbers::pi_v` (with the variable type also upgraded `float` → `double` so the conversion isn't truncated back to float at assignment). The 4 inline `expectedMask[13]` literals were reverted from `1` back to `0` to match the engineer's analytical oracle. With both changes applied, all 31 tests pass and SIMPLNX is bit-identical to the engineer's `test_design.md` oracle. + +The archive itself was NOT regenerated. The archive's input data was always correct; the issue was a precision bug in SIMPLNX's consumption of that data and a test that had been bent to track the bug. diff --git a/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureFaceMisorientations.md b/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureFaceMisorientations.md new file mode 100644 index 0000000000..3a9b912a93 --- /dev/null +++ b/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureFaceMisorientations.md @@ -0,0 +1,59 @@ +# Exemplar Archive Provenance: Inlined in Test + +This sidecar records how the test data used by `ComputeFeatureFaceMisorientationFilter`'s Class 1 unit test was generated.

The algorithm reads only `FaceLabels`, not vertex coordinates, so the geometric layout is arbitrary; the row-stacked structure is purely for human readability. + +2. **Feature structure:** 41 + 4 = 45 features (indices 0–44). Feature 0 is a sentinel/unused (phase `999`). Features 1–4 are phase 1 (Hex_High), 5–8 phase 2 (Cubic_High), ..., 37–40 phase 10 (Trigonal_Low), 41–44 phase 11 (Trigonal_High, added during this V&V cycle). + +3. **Ensemble structure:** 12 + 1 = 13 phase entries (index 0 = sentinel `999`; indices 1–11 = Laue-class indices 0–10). Phase `i` has `CrystalStructure[i] = i - 1` for `i = 1..11`, so phase 1 → CrystalStructure 0 (Hex_High), phase 2 → CrystalStructure 1 (Cubic_High), ..., phase 11 → CrystalStructure 10 (Trigonal_High). + +4. **Orientations (`AvgEulerAngles`):** Each Laue class block uses four orientations: `(φ1, Φ, φ2) = (0°, 0°, 0°)`, `(45°, 0°, 0°)`, `(90°, 0°, 0°)`, `(180°, 0°, 0°)`. With `Φ = φ2 = 0`, these are pure rotations about the c-axis. The choice is deliberate: pure c-axis rotations allow closed-form symmetry-group reduction (the c-axis is the principal symmetry axis of each Laue class), so the expected misorientation is just `|Δφ1|` modulo the c-axis n-fold rotation. + +5. **Face labels:** 34 + 3 = 37 entries. The first 30 entries are organized as Laue-class blocks of 3 boundary types: A↔B (φ1 0° vs 45°), A↔C (0° vs 90°), A↔D (0° vs 180°). Entries 30–33 are the four invalid-face edge cases: (0, 1) background-front, (1, 0) background-back, (1, 5) different-phase forward, (5, 1) different-phase reverse. Entries 34–36 are the Trigonal_High boundaries added during this V&V cycle. + +6. **Expected values:** Derived in closed form from the c-axis n-fold rotation of each Laue class. See the V&V report's Oracle table for the full per-class derivation. The Trigonal_High values (45°, 30°, 60°) match Trigonal_Low — the additional mirror planes in -3m do not reduce pure c-axis rotation magnitudes further. + +7. **Conversion path in the test:** The Euler angles are stored in degrees as `AvgEulerAngles`. The test first runs `ChangeAngleRepresentationFilter` (degrees → radians), then `ConvertOrientationsFilter` (Euler → quaternion, writing `AvgQuats`), then `ComputeFeatureFaceMisorientationFilter` itself. This conversion chain mirrors the standard SIMPLNX EBSD pipeline, so the test exercises the real production code path for converting hand-specified Euler angles into the quaternion format the algorithm consumes. + +The dataset is inlined in `src/Plugins/OrientationAnalysis/test/ComputeFeatureFaceMisorientationTest.cpp` namespace `curated` (function `CreateTestDataStructure()`). + +## Canonical oracle output + +| DataPath | Source of expected values | +|----------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| `/triangle_geom/FaceData/NXFaceMisorientationColors` | Class 1 analytical (closed-form symmetry-group reduction).

Artifacts at `/Users/mjackson/Desktop/F6_AB_Test/` (input `.dream3d` + 3 output `.dream3d` + comparison script + run results). **Post-backport result: 6.5.172 produces BIT-IDENTICAL output to SIMPLNX on the F#6 fixture** — all 18 per-pair `CAxisMisalignmentList` entries + 6 per-feature `AvgCAxisMisalignments` entries byte-compared and confirmed identical. Five deviations observed (D6 added 2026-06-04 after A/B): **D1 (divisor bug)** — 6.5.171 produces `avg[F2]=7.5°, avg[F5]=6.25°, avg[F6]=2.5°` (the predicted-buggy values); 6.5.172 (commit `c50223a46`) and SIMPLNX both produce the analytical-correct `10°, 8.333°, 5°`. **Bonus D1 symptom**: 6.5.171 produces `avg[F3]=0.0` for the all-non-hex-neighbor case (the buggy divisor stays > 0 so the formula evaluates `0.0/2=0` instead of falling through to `NaN`); fixed in 6.5.172 and SIMPLNX (both return `NaN`). **D2 (avg-array fillValue uncertainty)** — confirmed DORMANT on current SIMPLNX in-memory DataStore backend (F1 avg=10.000000 exactly proves the array WAS zero-initialized as the algorithm assumes). Still flagged for future OOC backends. **D4 (PR #1472 EbsdLib quat→matrix swap)** — pre-D4-backport drift `~1e-6°` per-pair, `~2e-5°` per-feature avg (existing doc note's `~0.0001°` is ~100× conservative). **Backported to 6.5.172 commit `5adc45df0` via Eigen + double precision conversion** following the FindAvgCAxes precedent. Post-backport: 6.5.172 matches SIMPLNX bit-for-bit. **D5 (PR #1438 hex-warning visibility downgrade)** — re-classified after A/B: SIMPLNX algorithm-level execute-time warning still surfaces correctly via `Result<>::warnings()` (visible to CLI nxrunner users); only the filter-side *preflight banner* is now GUI-only. UX downgrade, not warning-channel regression. **D6 (NEW — Hex_Low support gap, surfaced 2026-06-04)** — legacy 6.5.171 restricts hex-hex gate to Hex_High only; SIMPLNX accepts both Hex_High and Hex_Low. Not observable on the F#6 fixture (no Hex_Low features). **Backported to 6.5.172 commit `5adc45df0`** bundled with D4. | +| Bug flags | **One real bug fixed during this V&V cycle** — D1, divisor reassigned inside inner j-loop (sibling of F#2 ComputeFeatureNeighborMisorientations D1). Confirmed in `bug_triage.md` as Bug #3 (production-relevant: the shipping `EBSD_File_Processing/EBSD_Hexagonal_Data_Analysis.d3dpipeline` runs this filter with `find_avg_misals=true`). Fixed 2026-06-04 at `Algorithms/ComputeFeatureNeighborCAxisMisalignments.cpp:111`; verified via the `Realistic Microstructure (exposes divisor bug)` test which FAILED on pre-fix code (F2, F5, F6 per-feature averages wrong) and PASSES on the post-fix code. **One latent suspect** — D2, avg-array fillValue uncertainty. Surfaced by the retroactive report; not exercised by the V&V fixtures (which happen to land on hex-hex first for every feature that has `find_avg_misals=true` and a non-zero average). Worth a follow-up confirmation against `DataStoreUtilities::CreateDataStore` default-init behavior. | +| V&V phase | **All V&V work complete per V2 policy.** Class 1 + Class 4 oracle confirmed against 5-test suite; divisor bug fixed; circular-oracle archive retired; legacy A/B by source inspection; user-facing doc updated.

Phase mismatches and non-hexagonal Laue classes write `NaN` instead. When `find_avg_misals=true`, a per-feature `AvgCAxisMisalignments` array is also produced — the arithmetic mean of the non-NaN entries in each feature's `CAxisMisalignmentList`. + +The filter is the c-axis analog of `ComputeFeatureNeighborMisorientationsFilter`: same outer/inner loop structure, same `find_avg_misals` per-feature aggregation, same `NeighborList` output shape. The crystal-math kernel is different — c-axis misalignment is a **scalar projection** of the rotation onto the z-axis, not a full crystal misorientation — so this filter does NOT route through `LaueOps::calculateMisorientation` and is therefore **not affected by the EbsdLib 2.4.1 precision improvement** that surfaced as a deviation in F#1/F#2/F#4/F#5 of this V&V cycle. + +The shipping pipeline `pipelines/EBSD_File_Processing/EBSD_Hexagonal_Data_Analysis.d3dpipeline` runs this filter with `find_avg_misals: true`, making D1 (the divisor bug) a **production-relevant correctness issue** for anyone running the hex-data-analysis pipeline on mixed-phase EBSD inputs. + +## Algorithm Relationship + +*Classification:* **Port (with UUID reassignment + name rename + one inherent divisor-bug fix during this V&V cycle).** + +*Evidence:* Cross-checked SIMPLNX `Algorithms/ComputeFeatureNeighborCAxisMisalignments.cpp::operator()()` against legacy `FindFeatureNeighborCAxisMisalignments.cpp::execute()`.

The legacy result depends on the *order* in which neighbors appear in the per-feature `NeighborList`: if the last-iterated neighbor is hex-hex same-phase, the divisor used is the full neighbor-list length (incorrect); if the last neighbor is non-hex or different-phase, the divisor is decremented by 1 from the full length (the per-mismatch decrement at line 150 happens to be the last write to `hexNeighborListSize`). The legacy result is therefore correct in some cases by accident and wrong by up to `(N-K) / N` of the true value in others, where N is the neighbor count and K is the number of hex-hex same-phase neighbors. + +The bug is **not observable on the legacy SIMPLNX exemplar dataset** (`7_5_simplnx_test_file_25x50_Hex.dream3d` — hex-phase-only, so no mismatch decrements ever fire). The bug **IS observable** on the V&V `Realistic Microstructure (exposes divisor bug)` fixture, which constructs a 10×10×1 microstructure with mixed hex (F1, F2, F4, F5, F6) and cubic (F3) features. Three of the six features have neighbor lists that fire the bug (F2, F5, F6), with measured pre-fix averages of `7.500°`, `6.250°`, `2.500°` instead of the correct `10.000°`, `8.333°`, `5.000°`. + +**Additional symptom (surfaced by empirical A/B testing 2026-06-04):** for features whose entire neighbor list is non-hex (F3 in the V&V fixture), legacy 6.5.171 produces `avg = 0.0` whereas the correct behavior is `avg = NaN`. The mechanism: the buggy code reassigns `hexNeighborListSize` to the full list size at the top of each j-iteration and decrements it in the non-hex else-branch. On a 3-neighbor all-non-hex list, the iteration sequence is: j=0 (assign hex=3, decrement to 2); j=1 (assign hex=3, decrement to 2); j=2 (assign hex=3, decrement to 2). Final `hexNeighborListSize = 2`. The post-loop `if(hexNeighborListSize > 0)` branch is then true → `avg = 0.0 / 2 = 0.0` (the accumulator is 0 because no hex-match contributions were ever added). The intended behavior (executed correctly under the post-fix code) is for `hexNeighborListSize` to decrement to 0 after all three non-hex matches, falling through to the `else: avg = NaN` branch. Empirically: 6.5.171 produces `avg[F3] = 0.0`; 6.5.172 backport and SIMPLNX both produce `avg[F3] = NaN`. + +**Root cause:** **Bug** in both legacy DREAM3D 6.5.171 and SIMPLNX pre-fix. + +The legacy code at `Source/Plugins/OrientationAnalysis/OrientationAnalysisFilters/FindFeatureNeighborCAxisMisalignments.cpp:280` and the SIMPLNX pre-fix code at `Algorithms/ComputeFeatureNeighborCAxisMisalignments.cpp:111` both contain `hexNeighborListSize = currentNeighborList.size();` (or the legacy `hexneighborlistsize = neighborlist[i].size();`) *inside* the inner per-neighbor j-loop. The intended behavior is for `hexNeighborListSize` to start each outer-loop iteration (per feature) at the neighbor-list size and then decrement by 1 for each phase-mismatched neighbor (line 150: `hexNeighborListSize--;`). Because the reassignment happens at the *top* of each j-iteration, the decrement from the *previous* iteration is clobbered. Only the *last* j-iteration's match/mismatch state actually affects `hexNeighborListSize`: if the last neighbor is hex-hex same-phase, the assignment runs and the decrement doesn't, so the final divisor is N; if the last neighbor is non-hex or different-phase, both the assignment and the decrement run, so the final divisor is N - 1. + +The SIMPLNX fix (2026-06-04) moves the `hexNeighborListSize = currentNeighborList.size();` assignment from line 111 to before the inner j-loop (alongside `currentMisalignmentList.resize(...)` at line 106), so the assignment runs once per outer-loop iteration (per feature) and the decrement is preserved across j-iterations. The result is the mathematically correct divisor: the number of hex-hex same-phase neighbors. + +The bug went undetected for the lifetime of both implementations because: + +1. **The legacy 6.5.171 implementation had no automated test coverage of the `FindAvgMisals=true` path on mixed-phase data.** Legacy DREAM3D's CI tested filters with default parameter values; this parameter defaults to false in many user-facing pipelines and the test infrastructure didn't sweep over both values. +2. **The SIMPLNX Port preserved the bug** and the existing exemplar dataset was hex-phase-only. The exemplar would have happily passed even on the buggy code, because the per-mismatch decrement branch never fires on hex-only data. +3. **PR #1467 ("OEM-reviewed cleanup") signed off on the buggy code.** The review focused on naming, comments, and structure — not on the inner-loop divisor invariant. +4. **The retroactive bug-triage cycle (2026-05) caught it** by source inspection. Documented in `/Users/mjackson/Desktop/bug_triage.md` as Bug #3 (sibling of Bug #2 / F#2 D1). + +**Affected users:** Anyone running DREAM3D 6.5.171 or SIMPLNX pre-2026-06-04 with `FindAvgMisals=true` / `find_avg_misals=true` on data containing features with mixed hex / non-hex neighbor lists. **Production-relevant via shipping pipeline.** The reference pipeline `pipelines/EBSD_File_Processing/EBSD_Hexagonal_Data_Analysis.d3dpipeline` runs this filter with `find_avg_misals: true`. Any user running that pipeline on multi-phase EBSD data containing at least one cubic, tetragonal, or trigonal phase will have produced incorrect per-feature `AvgCAxisMisalignments` values. + +**Recommendation:** **Trust SIMPLNX (post-2026-06-04 fix).** The pre-fix per-feature `AvgCAxisMisalignments` values from both DREAM3D 6.5.171 and pre-fix SIMPLNX are mathematically incorrect for any feature with a mixed-phase neighbor list. Users migrating from 6.5.171 should expect per-feature averages to shift toward the mathematically correct value, with the shift size proportional to the fraction of phase-mismatched neighbors per feature. + +A legacy backport of `FindFeatureNeighborCAxisMisalignments.cpp` with the same fix (move the `hexneighborlistsize` reassignment outside the inner loop) is available on the `v6_5_172` branch of `/Users/mjackson/DREAM3D-Dev/DREAM3D`, bundled with the sibling `FindMisorientations` fix in commit `c50223a46` (or `c6759e81a`, depending on remote sync state). + +--- + +## ComputeFeatureNeighborCAxisMisalignmentsFilter-D2 + +| Field | Value | +|------------------|------------------------------------------------------------------------------------------------------| +| **Deviation ID** | `ComputeFeatureNeighborCAxisMisalignmentsFilter-D2` | +| **Filter UUID** | `636ee030-9f07-4f16-a4f3-592eff8ef1ee` | +| **Status** | active (latent — empirically confirmed DORMANT on current SIMPLNX in-memory DataStore; may surface on future OOC backends) | + +**Symptom:** Latent.

If `CreateArrayAction` does not zero-initialize the array when `fillValue` is empty (the underlying behavior depends on the `DataStoreUtilities::CreateDataStore` implementation and the IOCollection's default-init contract), the accumulator starts from undefined or implementation-defined state, and the per-feature average is wrong by exactly that initial garbage value. + +**Root cause:** **Bug** (latent) in SIMPLNX. The filter's `preflightImpl` at lines 125-127 of `ComputeFeatureNeighborCAxisMisalignmentsFilter.cpp` constructs the `CreateArrayAction` without a fillValue: + +```cpp +auto createArrayAction = std::make_unique( + DataType::float32, + featurePhases.getIDataStore()->getTupleShape(), + std::vector{1}, + pAvgCAxisMisalignmentsPathValue); +``` + +The algorithm at line 142 assumes the array starts at zero (`getValue(featureIdx) + ...`). If `DataStoreUtilities::CreateDataStore` zero-initializes by default (which it currently does for the in-memory `DataStore` constructor — `m_DataStore = std::vector(numTuples * numComponents);` value-initializes), the bug is dormant. But this behavior is implementation-detail of the underlying DataStore type and is not enforced by the `CreateArrayAction` contract. + +This was not exercised by any V&V fixture because the realistic-microstructure fixture happens to have every feature with `find_avg_misals=true` and a non-zero expected average start with a hex-hex first-neighbor (F1=F2 hex-hex first, F2=F1 hex-hex first, F4=F1 hex-hex first, F5=F2 hex-hex first, F6=F3 NON-hex first but F6's expected avg is 5° from a single hex-hex contribution — so F6 reads its initial value before the first hex-hex write at j=1, exposing the read pattern but the actual default-init behavior in the in-memory build is zero so the test passes). + +**Affected users:** Anyone running this filter on SIMPLNX with `find_avg_misals=true` on a backend where `DataStoreUtilities::CreateDataStore` does not zero-initialize.

Either change is a one-line edit.

Legacy writes `NaN` for those features' misalignment entries; SIMPLNX computes the real c-axis misalignment. + +**Recommendation:** **Trust SIMPLNX.** The c-axis math is correct for both hex Laue classes; the legacy restriction was overly conservative. **Backported to 6.5.172 on 2026-06-04** (commit `5adc45df0`) bundled with D4 (Eigen+double conversion). Post-backport: legacy `FindFeatureNeighborCAxisMisalignments` now accepts both Hex_High and Hex_Low pairs, identical to SIMPLNX. + +--- + +## Non-deviations (algorithm characteristics common to both filters) + +The following behaviors are NOT deviations — SIMPLNX (post-D1 fix) and DREAM3D 6.5.171 (with D1 still present) agree on them where D1 is not exercised. Captured here so future engineers don't re-discover them and propose them as deviations. + +### NaN entry on phase mismatch and non-hex Laue class + +Both implementations write `NaN` (via `std::nanf("")` or the C macro `NAN`) into the per-neighbor `CAxisMisalignmentList` entry when the focal feature's phase differs from the neighbor's phase, or when the shared phase's Laue class is not `Hexagonal_High` (or `Hexagonal_Low` — both are accepted). **Both filters share this behavior** — algorithm characteristic, not a defect. + +### Per-feature outer-loop iteration starts at index 1 (skips background feature 0) + +Both implementations iterate `for(size_t i = 1; i < totalFeatures; i++)` in the per-feature outer loop, skipping the background feature at index 0. The `CAxisMisalignmentList[0]` and `AvgCAxisMisalignments[0]` entries are therefore left at their initialized default values (empty list and `0.0f`, respectively). **Both filters share this behavior**. + +### Default output array name rename (formerly proposed as D3) + +PR #1438 renamed the default output array from `"AvgCAxisMisalignments"` to `"AvgNeighborCAxisMisalignments"`, and reworded the parameter labels: +- `"C-Axis Misalignment List"` → `"Feature C-Axis Misalignment NeighborList"` +- `"Average C-Axis Misalignments"` → `"Feature Average C-Axis Misalignments"` + +This is **user-facing migration noise**, not a behavioral deviation. The SIMPLNX backwards-compat path (PR #1588) preserves the SIMPL conversion semantics. Existing pipeline files in the repo were re-saved with the new name; user-saved pipelines that explicitly named arrays still work. Documented here for completeness; not a numbered deviation. + +### EbsdLib 2.4.1 CubicOps precision improvement does NOT apply + +Unlike F#1 / F#2 / F#4 / F#5 of this V&V cycle, this filter does NOT route through `LaueOps::calculateMisorientation` or `CubicOps::calculateMisorientationInternal`. The algorithm computes c-axis vectors directly from the orientation matrix (`R^T · [0,0,1]`) and takes `arccos(c1·c2)` without any cubic-symmetry-operator search. The EbsdLib 2.4.1 precision improvement therefore has no effect on this filter's output, and there is no `D-precision` entry analogous to the other filters in the cycle. diff --git a/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureNeighborCAxisMisalignmentsFilter.md b/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureNeighborCAxisMisalignmentsFilter.md new file mode 100644 index 0000000000..5794abe459 --- /dev/null +++ b/src/Plugins/OrientationAnalysis/vv/provenance/ComputeFeatureNeighborCAxisMisalignmentsFilter.md @@ -0,0 +1,254 @@ +# Exemplar Archive Provenance: Inlined in Test + +This sidecar records how the test data used by `ComputeFeatureNeighborCAxisMisalignmentsFilter`'s Class 1 and Class 4 unit tests was generated.

This expands the set of checked **Features** to include neighbors that are nearby but do not share a direct face/edge/vertex with the child **Feature**. Enable this option if non-contiguous neighbors were used during the original grouping step. Typically the [Compute Feature Neighborhoods](ComputeNeighborhoodsFilter.md) filter is used to generate the **Non-Contiguous Neighbor List**. The *Multiples of Average Diameter* parameter on that filter has a large effect on the final **Grouping Density** value that is computed. #### Find Checked Features When enabled, the filter produces an additional output array (**Checked Features**) at the **Feature** level. For each **Feature** that was checked during the density computation, this array records which **Parent Feature** checked it. Since a **Feature** may be checked by multiple **Parent Features** (as a neighbor of children belonging to different parents), the assignment goes to the **Parent Feature** with the **largest Parent Volume**. This provides a way to see which parent had the strongest influence over each region of the microstructure. +**Tie-break behavior:** When two or more **Parent Features** have *exactly equal* **Parent Volumes** and both check the same **Feature**, the first-processed parent (the one with the lower **Parent ID**) keeps the assignment. The strictly-greater comparison (`>`) means equal-volume parents do not overwrite earlier claims. This is deterministic and matches the legacy DREAM3D `FindGroupingDensity` behavior. + ### Worked Example @@ -47,13 +56,13 @@ Consider a 20x5 2D **Image Geometry** with unit spacing (1.0 x 1.0 x 1.0), conta - Features 1, 2, 3 belong to Parent 1 (Parent Volume = 45, i.e. 10 + 20 + 15 cells) - Features 4, 5 belong to Parent 2 (Parent Volume = 55, i.e. 25 + 30 cells) -| Feature | Cells | Volume | Parent | Contiguous Neighbors | -|---------|-------|--------|--------|----------------------| -| 1 | 10 | 10.0 | 1 | {2} | -| 2 | 20 | 20.0 | 1 | {1, 3} | -| 3 | 15 | 15.0 | 1 | {2, 4} | -| 4 | 25 | 25.0 | 2 | {3, 5} | -| 5 | 30 | 30.0 | 2 | {4} | +| Feature | Cells | Volume (cells) | Parent | Contiguous Neighbors | +|---------|-------|----------------|--------|----------------------| +| 1 | 10 | 10.0 | 1 | {2} | +| 2 | 20 | 20.0 | 1 | {1, 3} | +| 3 | 15 | 15.0 | 1 | {2, 4} | +| 4 | 25 | 25.0 | 2 | {3, 5} | +| 5 | 30 | 30.0 | 2 | {4} | **Parent 1:** Child features {1, 2, 3} plus their contiguous neighbors include feature 4 (neighbor of feature 3).

Hierarchical reconstructions involve more than one level of segmentation, creating a **Feature** to **Parent Feature** relationship (e.g., grains grouped into reconstructed parent grains). +- The filter was verified by generating a small data set that exercises each code path and combination of featureIds. The final calculations were done by hand and then verified by executing the filter. +- The result is that the filter generates the expected output values + + +## Resolution (V&V outcomes — 2026-05-27) + +| Topic | DRAFT-tentative finding | Final confirmed finding | +|---|---|---| +| Algorithm Relationship | Port (with rename `Find→Compute`) | **Port** — confirmed. The SIMPLNX algorithm is a line-by-line translation of the legacy `FindGroupingDensity::execute()` from `tuks188/DREAM3D` `feature/770_Grouping_Density`. Six port-time deltas documented in the V&V report, none change output. | +| Oracle class | Class 1 (Analytical) primary, optionally Class 4 (Invariant) | **Class 1 + Class 4 confirmed.** Hand-derivation embedded in V&V report; invariant predicates added inline in the test (sentinel `-1.0f`, `density ≤ 1.0`, `density > 0 ∨ == -1.0f`, CheckedFeatures range). Second-engineer review skipped — set-union arithmetic on 5-feature toy dataset + bit-identical cross-check against independently-built legacy. | +| Legacy comparison | Not yet run | **Done. No deviations.** All 4 `(UseNonContiguous, FindCheckedFeatures)` configurations produce bit-identical output between SIMPLNX and the locally-rebuilt legacy `FindGroupingDensity` (`/Users/mjackson/DREAM3D-Dev/DREAM3D` 6.5.172 branch with feature-branch sources).

Added: empty-parent sentinel test (Class 4) + preflight error -15672 test (gap closed). Kept: 3 existing preflight error tests + SIMPL backwards-compat test. | +| Deviation entries (`ComputeGroupingDensity-D`) | Placeholder pending comparison | **None.** No deviations observed across all 4 configurations. See `vv/deviations/ComputeGroupingDensityFilter.md` for the comparison method, fixture, SHA512, and migration recommendation. | +| Algorithm review (`review-algorithm`) | Not visible from PR history | **Done.** Code-comment cleanup applied (sentinel documented, deleted-special-members trailing comments removed, throwaway-placeholder pattern explained, FindDensitySpecializations + FindDensityGrouping class docs added). Memory / formatting / overflow concerns mitigated by the engineer. Tie-break behavior added to the user-facing filter doc. | +| Filter documentation (`review-filter-docs`) | "Excellent — empty References section is the one defect" | **Updated.** Added Required Input Sources section with MyST cross-links to upstream producer filters. Stated volume units explicitly. MyST-linked the inline Compute Feature Neighborhoods mention. Italicized the `-1.0` sentinel as a value reference. References + Example Pipelines remain empty (no published paper; no shipping pipeline currently uses this filter). | +| Verification archive (OneDrive) | Not yet created | **Materially captured by the v2 GitHub Data_Archive release** — the v2 tarball contains the input file, all 4 legacy and SIMPLNX outputs, the comparison script + report, the legacy and SIMPLNX pipelines, and the hand-review sign-off ReadMe. OneDrive duplication can be done at SBIR deliverable assembly. | + + +## Algorithm Relationship + + +*Classification:* **Port** + +*Evidence:* The SIMPLNX algorithm at `Algorithms/ComputeGroupingDensity.cpp` (219 lines) is a line-by-line translation of the legacy `FindGroupingDensity::execute()` on `tuks188/DREAM3D` `feature/770_Grouping_Density` (469-line `.cpp` file; ~80-line algorithm body). Identical control flow (nested parent×feature loops + neighbor-list walks), identical sentinel (`-1.0f` when `totalCheckVolume == 0.0f`), identical density formula (`curParentVolume / totalCheckVolume`), and a preserved-from-legacy variable-name lineage (`totalCheckVolume` → `totalFeatureCheckVolume`, `checkedfeaturevolumes` → `checkedFeatureVolumes`). Same SIMPL UUID retained via `SimplnxCoreLegacyUUIDMapping.hpp` + SIMPL conversion fixture at `test/simpl_conversion/6_5/ComputeGroupingDensityFilter.json`. **Important caveat:** the legacy filter was never officially released in any DREAM3D 6.5.x — it lived on an un-merged feature branch on a contributor fork. However, a small number of important customers consumed a custom DREAM3D 6.5.x build that included this filter, and those customers have downstream data dependent on its output.

Determine the location of the c-axis in the sample *reference frame* for the rotated quaternions for all **Elements**.

Average the locations and store the average for the **Feature** +### What is the C-Axis? -*Note:* This **Filter** will only work properly for *Hexagonal* materials. The **Filter** does not apply any symmetry -operators because there is only one c-axis (<001>) in *Hexagonal* materials and thus all symmetry operators will leave -the c-axis in the same position in the sample *reference frame*. However, in *Cubic* materials, for example, the {100} -family of directions are all equivalent and the <001> direction will change location in the sample *reference frame* when -symmetry operators are applied. +In hexagonal crystal structures (such as titanium, magnesium, and zinc), the *C-axis* is the unique crystallographic direction that runs along the long axis of the hexagonal unit cell (the [001] direction). This axis is important because many mechanical and physical properties of hexagonal materials vary depending on whether they are measured along or perpendicular to the C-axis. -This filter will error out if **ALL** phases are non-hexagonal. Any non-hexagonal phases will have their computed values set to NaN value. +![Fig. 1: The C-axis in a hexagonal unit cell.](Images/ComputeAvgCAxes_HexagonalCAxis.png) -The output is a direction vector for each feature. +### How This Filter Works + +Each **Cell** (voxel) in a grain has its own measured orientation. This filter determines where each cell's C-axis points in the physical sample coordinate system, then averages those directions across all cells belonging to the same **Feature**: + +1. For each **Cell**, the filter uses the cell's orientation (quaternion) to rotate the crystal [001] direction into the sample reference frame. +2. The rotated C-axis directions are accumulated for each **Feature**, ensuring all directions point into the same hemisphere for a consistent average. +3. The accumulated directions are normalized to produce a unit vector for each **Feature**. + +### Hexagonal Materials Only + +This filter only produces valid results for hexagonal phases (6/mmm or 6/m symmetry). In hexagonal materials, the C-axis is unique -- there is only one [001] direction, so crystal symmetry does not create ambiguity. + +In cubic materials, the [001], [010], and [100] directions are all crystallographically equivalent. Applying symmetry operators would move the [001] direction to different positions in the sample frame, making a simple average meaningless. For this reason, the filter **silently skips non-hexagonal cells** during accumulation. A **Feature** whose contributing cells are *all* non-hexagonal (or which has no cells assigned to it at all) will have its output set to **NaN**. + +The filter will produce an error if no hexagonal phases are present in the data (`-76402`: "No phases that have a crystal symmetry of Hexagonal (6/mmm or 6/m) were found."). + +### Required Input Sources + +This filter operates on previously

Verification used a **Class 1 (Analytical) hand-built 11-cell / 8-feature dataset** with closed-form expected values for F0–F6 plus a **Class 4 unit-vector invariant** (`||AvgCAxes|| == 1.0`) for F7, which was deliberately placed on the antipodal-flip cancellation boundary; results were cross-checked three-way against DREAM3D 6.5.171 (official release) and a custom 6.5.172 backport branch. **SIMPLNX is bit-identical to 6.5.172 across all 8 features**, conclusively isolating the four documented differences vs 6.5.171 (D1 — `counter==0 → NaN` vs `(0,0,1)` rescue at F0/F5/F6; D2 — precision-sensitive direction + unit-vector vs unnormalized magnitude at F7) to the SIMPLNX-era design changes (float→double accumulation, Eigen-style math, `counter==0 → NaN` at finalize, and final per-feature normalize). + +## Algorithm Relationship + + +*Classification:* **Port** with Minor Changes + +*Evidence:* The SIMPLNX algorithm at `Algorithms/ComputeAvgCAxes.cpp` (181 lines) is a translation of the legacy `FindAvgCAxes::execute()` from `DREAM3D/Source/Plugins/OrientationAnalysis/OrientationAnalysisFilters/FindAvgCAxes.cpp` (DREAM3D 6.5.171). +- Same SIMPL UUID retained via `OrientationAnalysisLegacyUUIDMapping.hpp` + SIMPL 6.4 and 6.5 conversion fixtures at `test/simpl_conversion/6_*/ComputeAvgCAxesFilter.json`. +- The control flow is preserved: phase-validity preflight → per-cell accumulation loop (passive-quaternion → orientation matrix → transpose → c-axis · `[0,0,1]`, antipodal-flip aware) → per-feature finalize (divide-by-count or `counter==0` handling). +- However, PR #1438 ("ENH: Microtexture related filter cleanup") applied intentional silent changes that distinguish this from a pure line-by-line port; +- PR #1472 applied an EbsdLib API refactor; +- PR #1582 added cancel checks +- Phase-7 V&V refactor consolidated the no-valid-contributions handling AND added a final per-feature normalize step so the output contract is unit C-axis vectors. All seven changes are listed below. + +*Port-time deltas (numerical / semantic Deviations vs legacy — see Phase 9):* + +1. **Float → double accumulation** (PR #1438) — All inner-loop accumulation now uses `Eigen::Vector3d`, `OrientationD`, `QuatD`, `Matrix3dR`. Legacy used `float` throughout. Contributes to Deviation D2 (precision-boundary antipodal flip). +2. **`counter[currentFeatureId]++` reordered** (PR #1438) — Moved from *after* the antipodal-flip dot-product test to *before* it. Changes which divisor is used for the first voxel's running-average reference; can produce sign flips on the first voxel of each feature vs. legacy. Contributes to Deviation D2. +3. **Error codes re-numbered + preflight warning removed** (PR #1438) — Legacy `-6402` → SIMPLNX `-76402`; legacy `-6403` → `-76403`; legacy preflight warning `-6401` ("Selected crystal structure phase is not Hexagonal") was *deleted entirely* and replaced with a non-error `preflightUpdatedValues` "Crystal Symmetry Warning": entry. API-surface Deviation candidate (no numerical impact on this V&V dataset). +4. **EbsdLib API refactor** (PR #1472) — `EbsdLib::` → `ebsdlib::` namespace; explicit `OrientationTransformation::qu2om(...)` + `OrientationMatrixToGMatrixTranspose(oMatrix)` helper call replaced by inline `ebsdlib::QuaternionDType(...).toOrientationMatrix()` + `oMatrix.transpose() * cAxis`. Convention parity between the new `toOrientationMatrix()` and the legacy `qu2om` verified on the V&V dataset (6.5.172 backport using legacy EbsdLib still bit-matches SIMPLNX, so the conventions are functionally aligned). +5. **Cancel checks added** (PR #1582) — `m_ShouldCancel` guards in the per-cell loop and the per-feature normalization loop. UX-only; no algorithmic effect on completed runs. +6. **`counter==0` → NaN at feature loop, feature loop starts at 0** (Phase-7 V&V refactor) — In the per-cell loop, non-hex cells are simply `continue`d (no in-place NaN write, no counter increment). The per-feature finalize loop now starts at `currentFeatureId = 0` (legacy starts at 1) and writes `(NaN, NaN, NaN)` whenever `counter[feature] == 0`. This consolidates all "no valid contributing voxels" handling at finalize and signals undefined output honestly. Drives Deviation D1 (F0, F5, F6). +7. **Final per-feature normalize** (Phase-7 V&V refactor) — After dividing the accumulated sum by `cellCount`, the result is now normalized to a unit C-axis vector before being stored. Legacy (6.5.171 and pre-refactor 6.5.172) returned the unnormalized average — magnitude was implicitly a within-feature coherence signal (1.0 for aligned, lower for diverging). The unit-vector contract better matches user expectations and downstream filters (which compute `acos(dot(a,b))` and need unit-magnitude inputs anyway). The antipodal-flip invariant guarantees `|sum| >= sqrt(cellCount)` so the divisor is never near-zero — no NaN guard needed. Widens Deviation D2 to include a magnitude difference (1.0 vs 2/3) at F7 in addition to the precision-sensitive direction. + +*Material PRs since baseline (2025-10-01):* + +- **#1438** — "ENH: Microtexture related filter cleanup" (merge `e6896714b`, 2025-10-25) — algorithm `+89/-76`, filter `+2/-3`.

All results should be within 5.0E-7 tolerance of each other. + +This makes `7_2_AvgCAxis.tar.gz` a **regression-style oracle pinned to a 6.6.379 special build** — closer to Class 5 (regression / golden-master with a "trust the legacy" assumption) than to any of the policy's preferred Class 1–4 oracles. The DREAM3D 6.6.379 special build itself was never independently verified, and per V&V policy line 33 ("Legacy 6.5.171 produced this output is never a valid oracle for correctness") this is doubly disqualified: it's not even 6.5.171 baseline — it's a later, divergent special build.

For each cell `i` in `cellSet`: compute the voxel c-axis `c_i = R(q_i).T · [0,0,1]` where `R(q)` is the standard quaternion → passive orientation matrix (standard 2015 Eq. 14 convention; the algorithm's `oMatrix.transpose() * (0,0,1)` is the active-rotation form). +3. Apply the running-average antipodal flip rule: process cells in cell-index order; for each cell after the first, if `c_i · (Σ prior c_j / count) < 0`, flip `c_i := -c_i`. +4. Sum the (possibly-flipped) `c_i`, divide by the cell count, then normalize: `AvgCAxes[f] = normalize((Σ c_i) / count)`.

Legacy DREAM3D 6.5.171 instead falls into a "counter==0 rescue" branch and writes `(0, 0, 1)` — a confusingly valid-looking c-axis output for a feature with no contributing data. + +This symptom manifests in three distinct scenarios: + +| Scenario | Example in V&V dataset | SIMPLNX | 6.5.171 | +|---|---|---|---| +| Placeholder feature 0 (never referenced by any cell) | F0 | NaN | (0, 0, 0) — initial state, untouched by legacy finalize loop | +| Feature has no cells assigned | F5 — declared in CellFeatureData with 8 tuples but no cell has `FeatureId == 5` | NaN | (0, 0, 1) — rescue fires | +| Feature has cells but all are non-hex | F6 — sole cell of F6 is Cubic_High phase, skipped in cell loop, counter never incremented | NaN | (0, 0, 1) — rescue fires | + +(For F0 specifically, legacy 6.5.171's finalize loop starts at index 1 and never visits feature 0; the array slot stays at its zero-initialized state. SIMPLNX's finalize loop starts at index 0 and writes NaN.) + +**Root cause:** **Algorithmic choice** during the SIMPLNX port. The refactored algorithm consolidates "no valid contributions" handling at the per-feature finalize loop: + +```cpp +// Cell loop: non-hex cells skip without writing anything +if(currentCrystalStructure != ebsdlib::CrystalStructure::Hexagonal_High && + currentCrystalStructure != ebsdlib::CrystalStructure::Hexagonal_Low) +{ + continue; +} +cellCount[currentFeatureId]++; + +// ... per-cell accumulation ... + +// Per-feature finalize loop (starts at index 0): +if(cellCount[currentFeatureId] == 0) +{ + avgCAxes[cAxesIndex] = NAN; + avgCAxes[cAxesIndex + 1] = NAN; + avgCAxes[cAxesIndex + 2] = NAN; +} +else +{ + // divide by cellCount, then normalize +} +``` + +The legacy DREAM3D 6.5.171 `FindAvgCAxes` instead writes `(0, 0, 1)` at the counter==0 case, and starts the finalize loop at index 1. The 6.5.172 backport (commit on branch `v6_5_172` at `/Users/mjackson/DREAM3D-Dev/DREAM3D`) retrofits both the SIMPLNX-style `counter==0 → NaN` write and the finalize-loop start-at-0 into the legacy code, producing **bit-identical** SIMPLNX output across F0, F5, and F6. + +**Affected users:** Anyone running the filter on EBSD data with one or more of: +- Multi-phase data including non-hexagonal phases (some features may end up all-non-hex) +- CellFeatureData with declared feature tuples that don't have cells assigned (sparse feature space) +- Pole-figure or texture-statistics pipelines that consume `AvgCAxes` downstream — the (0, 0, 1) legacy rescue value would silently propagate as a "real" c-axis; the SIMPLNX NaN allows correct downstream filtering. + +**Recommendation:** **Trust SIMPLNX.** Writing `NaN` is a more honest signal that the value is undefined for these features. The legacy `(0, 0, 1)` rescue was a side effect of the rescue branch design, not a meaningful crystallographic c-axis. Downstream consumers of `AvgCAxes` should expect and handle NaN appropriately (e.g., filter out NaN-valued features before computing pole figures or texture statistics). + +--- + +## ComputeAvgCAxesFilter-D2 + +| Field | Value | +|------------------|----------------------------------------| +| **Deviation ID** | `ComputeAvgCAxesFilter-D2` | +| **Filter UUID** | `453cdb58-7bbb-4576-ad5e-f75a1c54d348` | +| **Status** | active | + +**Symptom:** For features whose cell c-axes lie on the *antipodal-flip cancellation boundary* — where the running-average dot product evaluates to exactly zero in math but is precision-dependent in float32 — SIMPLNX and 6.5.171 produce different per-feature `AvgCAxes` outputs. After the Phase-7 normalize-at-finalize step, both implementations yield unit vectors, but with different magnitudes vs 6.5.171 (1.0 in SIMPLNX, 2/3 in 6.5.171) AND different directions. + +In the V&V toy dataset this fires at F7: three cells with c-axes `(0, 0, 1)`, `(0, +√3/2, 0.5)`, `(0, -√3/2, 0.5)`. The legacy 6.5.171 float-precision path takes the "no flip" branch and produces `(0, 0, 0.667)`. The SIMPLNX double-precision-Eigen path takes the "flip fires" branch and produces `(0, 0.866, 0.500)` (post-normalize). These are genuinely different c-axis directions (60° apart in 3D), NOT hex c≡-c equivalents — both are valid "average c-axes" of the same cell set under different sign-assignment choices. + +**Root cause:** **Precision + matrix-math style**. + +The relevant lines in `Algorithms/ComputeAvgCAxes.cpp` lines 118–122 compute the running-average reference and the antipodal-flip decision: + +```cpp +float64 cosAngle = ImageRotationUtilities::CosBetweenVectors(cellCAxis, runningCAxisAvg); +if(cosAngle < 0.0) +{ + cellCAxis *= -1.0f; +} +``` + +At F7 cell 10, the mathematically exact cosAngle is zero — the cell's c-axis is perpendicular to the running average. In SIMPLNX's `Eigen::Vector3d` double-precision path the computed `cosAngle` lands at a tiny negative value, firing the flip. In legacy 6.5.171's float-only path (or in a pure-double NumPy replay), the computed cosAngle lands at a tiny positive value, NOT firing the flip. The accumulated sums diverge to genuinely different directions. + +PR #1438 ("Microtexture related filter cleanup") changed the inner-loop accumulator from `float` to `Eigen::Vector3d` (double); this precision change is the proximate driver. The EbsdLib API refactor (PR #1472) replaced explicit `qu2om` + helper calls with inline `toOrientationMatrix()` — verified functionally equivalent by the 6.5.172 backport's matching output. The Phase-7 normalize-at-finalize step (V&V cycle) widens the deviation: pre-normalize, both implementations had magnitude 2/3 at F7; post-normalize, SIMPLNX has magnitude 1.0 while 6.5.171 still has 2/3 (since the legacy code never normalized). + +**Affected users:** Anyone running the filter on EBSD data containing features whose cell-level c-axes are arranged near the antipodal-flip cancellation boundary. In practice this is rare in natural EBSD data — it requires several cells with c-axes that summed (without flip) would lie nearly orthogonal to a previously-accumulated direction. The deliberately-pathological F7 test case demonstrates the sensitivity. **Users computing pole figures or per-feature texture statistics will get different magnitudes (1.0 vs ≤ 1.0) between SIMPLNX and 6.5.171, with the SIMPLNX magnitude being more predictable across pipelines (always unit-vector).** + +**Recommendation:** **Trust SIMPLNX.** The unit-vector contract matches the natural interpretation of "average c-axis direction" and is what downstream filters (`ComputeFeatureReferenceCAxisMisorientations`, `ComputeFeatureNeighborCAxisMisalignments`) need anyway (those filters compute `acos(dot(a, b))` and require unit-magnitude inputs). Where direction differs at the precision boundary, both directions are valid c-axis representatives of the underlying cells — there is no objectively "right" answer at exact cancellation. + +--- + +## Comparison build & library nuance + +The legacy DREAM3D 6.5.171 / 6.5.172 both use the **built-in EbsdLib/OrientationLib** inside the DREAM3D source tree (frozen at the 6.5.171 release point, with the user's targeted backport patches in the 6.5.172 branch).
