ENH: Ingest ITKParabolicMorphology into Modules/Filtering

[hjmjohnson]

Ingests ITKParabolicMorphology into Modules/Filtering/ParabolicMorphology/ via the v4 two-phase pipeline (#6204). Stacked on ingest-strategy-v4; rebases cleanly onto main once #6204 lands. Tracking: #6160.

What landed

Modules/Filtering/ParabolicMorphology/ with include/, test/, wrapping/, CMakeLists.txt, itk-module.cmake, README.md. Mode-A --no-ff --allow-unrelated-histories merge preserves 33 merges + 164 non-merge commits from upstream (git blame walks back to Richard Beare and other historical contributors).

Follow-up commits (per INGESTION_STRATEGY_v4.md):

Commit	Purpose
DOC: Add ParabolicMorphology README pointing at upstream	Module landing page + migration note
COMP: Remove ParabolicMorphology .remote.cmake (in-tree)	Drop remote-module configure-time fetch
ENH: Enable Module_ParabolicMorphology in configure-ci	Add to pyproject.toml CI matrix

Pre-submission review applied (4 additional commits):

Commit	Issue addressed
DOC: Add Beare 2008 IJ reference to README	Citation needed stable URL → IJ handle 1926/1370
COMP: Restore DESCRIPTION and add maintainer in itk-module.cmake	Module description carried over from .remote.cmake; replace stale upstream comment block
ENH: Add Python wrapping for binary filters	4 missing .wrap files (BinaryClose/Dilate/Erode/OpenPara) + Sharpening added to WRAPPER_SUBMODULE_ORDER
STYLE: Remove unused IJMacros.txt scaffolding	Insight Journal artifact, never referenced in test/CMakeLists.txt
STYLE: Rename Binary*Para to Binary*Parabolic	Public API naming consistency with sibling Parabolic*ImageFilter classes

Local verification

• pre-commit run --all-files — ✅ clean
• pixi run -e cxx configure-ci — ✅ Module_ParabolicMorphology:BOOL=ON
• cmake --build build -j10 — ✅ 350/350 targets after rename, 1084/1084 from full build
• ctest -R "Para|Parabolic" -j4 — ✅ 20/20 ParabolicMorphology tests pass (2 meta + 18 computational across erode / dilate / open / close / sharpen / DT / spacing / binary morphology)

Topology check: git rev-list --merges upstream/main..HEAD = 33 merges preserved (no linearization per feedback_ingest_merge_topology).

Phase B follow-up (deferred until this PR merges)

After merge, the standalone upstream archival is published via:

Utilities/Maintenance/RemoteModuleIngest/archive-remote-module.sh ParabolicMorphology

This runs the deletion commit on the upstream ITKParabolicMorphology repo, promotes MIGRATION_README.md → README.md (per feedback_ingest_archive_readme.md), and flips archived=true. Gated on this PR landing per the v4 strategy.

Greptile Summary

This PR ingests the ITKParabolicMorphology remote module into Modules/Filtering/ParabolicMorphology/ via the v4 two-phase pipeline, preserving the full upstream git history (33 merges + 164 commits). The ingest tooling (ingest-module-v4.sh, sanitize-history.py) also receives several improvements to handle new sanitization cases.

• Module landing: 30 C++ headers/implementation files, 11 Python wrapping descriptors, a test/ tree with 20 passing tests, and itk-module.cmake with correct dependencies; the ParabolicMorphology.remote.cmake remote fetch descriptor is removed and CI is updated via pyproject.toml.
• Tooling improvements: sanitize-history.py gains patch_drop_module_scaffolding to strip itk_module_examples(), cmake_policy(…), and doc-build option/if blocks; hash sidecar files are now allowed through universal text fixers to gain a trailing newline; ingest-module-v4.sh adds deny-passes for editor backup files and LICENSE/COPYING files.

Confidence Score: 4/5

The module code itself is well-tested (20/20 tests pass) and the CMake wiring is correct; the small issues are cosmetic carry-overs from upstream and a regex edge case in the ingestion tooling.

The ingested module code is functionally sound and all 20 tests pass. The two noteworthy items are: a lazy regex in _DOC_IF_BLOCK_RE that could leave malformed CMake if a doc-build block contains nested conditionals (affects future ingestions, not this one), and the unconditional stripping of LICENSE/COPYING files without any operator warning (relevant for future non-Apache-2.0 ingestions). The duplicate includes and wrong Doxygen brief are pure style carry-overs with no runtime impact.

Utilities/Maintenance/RemoteModuleIngest/sanitize-history.py (lazy-match regex) and ingest-module-v4.sh (silent LICENSE stripping) warrant a second look before the next wave of ingestions.

Important Files Changed

Filename	Overview
Modules/Filtering/ParabolicMorphology/itk-module.cmake	New in-tree module declaration with correct DEPENDS, TEST_DEPENDS, EXCLUDE_FROM_DEFAULT, and a static DESCRIPTION with DOI link; replaces the stale remote-module scaffolding.
Modules/Filtering/ParabolicMorphology/include/itkParabolicErodeDilateImageFilter.hxx	Core threaded erode/dilate implementation; uses legacy DynamicMultiThreadingOff + custom SplitRequestedRegion. Functionality is correct; contains commented-out debug code and an #if 1 guard around standard overrides (cosmetic carry-over from upstream).
Modules/Filtering/ParabolicMorphology/include/itkBinaryDilateParabolicImageFilter.h	Header for the binary dilation filter; Doxygen brief incorrectly says "erosion operation" instead of "dilation operation" — copy-paste error from the erode header carried in from upstream.
Modules/Filtering/ParabolicMorphology/include/itkBinaryDilateParabolicImageFilter.hxx	Implementation for binary dilation; has a duplicate #include "itkProgressAccumulator.h" (same in Erode/Close/Open hxx files) carried from upstream, harmless due to guards but should be cleaned up.
Utilities/Maintenance/RemoteModuleIngest/sanitize-history.py	Adds patch_drop_module_scaffolding (itk_module_examples, cmake_policy, doc-build blocks) and fixes is_skip_content to allow hash sidecars to receive trailing-newline fixup. The _DOC_IF_BLOCK_RE lazy match may incorrectly stop at a nested endif inside doc-build blocks, leaving malformed CMake.
Utilities/Maintenance/RemoteModuleIngest/ingest-module-v4.sh	Adds deny-passes for editor backup files (*~), and unconditionally strips LICENSE/COPYING files from ingested history without any warning — safe for Apache-2.0 modules but could silently drop attribution for future modules with different licenses.
Modules/Filtering/ParabolicMorphology/wrapping/CMakeLists.txt	Wrapping entry point listing all 11 filters in correct dependency order with itk_wrap_module/itk_end_wrap_module bookends; newly added binary filters are properly appended.
Modules/Remote/ParabolicMorphology.remote.cmake	Remote-module fetch descriptor correctly deleted now that the module is ingested in-tree.
pyproject.toml	Adds -DModule_ParabolicMorphology:BOOL=ON to the configure-ci CMake invocation so the module is built and tested in CI.
