The filter was verified analytically using a Class 1 hand-derived oracle on three small synthetic fixtures covering consistent, inconsistent, and multi-component cases (AF-1, AF-2, AF-3), plus Class 4 invariants on output shape and type. All six oracle assertions pass. The filter is a direct port of the SIMPL `CreateFeatureArrayFromElementArray` with no output-affecting changes; empirical A/B comparison (2026-07-23) confirmed bit-identical output against SIMPL 6.5.171 with no deviations. + +## Algorithm Relationship + +*Classification:* **Port** + +*Evidence:* The SIMPLNX algorithm at `Algorithms/CreateFeatureArrayFromElementArray.cpp` (95 lines) is a line-for-line translation of the SIMPL `CreateFeatureArrayFromElementArray` filter. Identical control flow: iterate over cell tuples, look up `featureIds[cellIdx]`, record first-seen tuple offset in `featureMap`, compare current value against first-seen per component, emit one warning on first mismatch, write current value to `createdDataStore[featureId * C + comp]` (last-writer-wins). The SIMPL UUID (`94438019-21bb-5b61-a7c3-66974b9a34dc`) differs from the SIMPLNX UUID (`50e1be47-b027-4f40-8f70-1283682ee3e7`) because the filter was re-UUID-ed during the SIMPL→SIMPLNX port; the legacy alias is maintained through `FromSIMPLJson()` and `test/simpl_conversion/6_5/CreateFeatureArrayFromElementArrayFilter.json`. + +*Port-time deltas that do not change output data:* + +1. `QVector` + linear search → `std::map` for `featureMap` — performance/API change; set-membership semantics and iteration order over cells unchanged. +2. SIMPL `EXECUTE_FUNCTION_TEMPLATE` macro → `ExecuteDataFunction(CopyCellDataFunctor{}, ...)` dispatch — API modernization; identical runtime dispatch on element data type. +3. Warning API: SIMPL used `notifyStatusMessage` guarded by `bool warningThrown = false;`; SIMPLNX uses `Result<>` warnings guarded by `result.warnings().empty()`. Both guards produce the same behavior: exactly **one** warning per execution when any feature's cell values are inconsistent. Confirmed by empirical A/B comparison (2026-07-23) — no behavioral delta. +4. Algorithm class extracted from `executeImpl` into `Algorithms/CreateFeatureArrayFromElementArray.{hpp,cpp}` — code organization change only (PRs #1301 and #1544). +5.
