The track layout library came in as a subproject of its own -- its own CMakeLists, its own install and export rules, its own include tree -- which only made the build harder to follow now that everything else is a module. It is part of the editor, so it lives where the editor lives. - editor/plan_*.cppm / plan_*.cpp: the fifteen interface units and twelve implementation units, flat in editor/ beside editorTerrain and orthophoto, with the plan_ prefix keeping them clear of what was already there (editor/turnouts is the preset catalogue, so the geometry is plan_turnout_geometry). - modules are named eu07.editor.plan_*, like every other module in the tree. - namespaces move under the editor's own: editor::plan, editor::plan::geometry, ::io, ::render. The library's old name is gone from the sources and the docs. - every moved file carries the MPL header the rest of the tree carries; it had none. version.hpp went with the subproject: macros only, and unused. - the umbrella header is dropped -- nothing imported it. - the unit tests survive the fold: editor/tests, behind EU07_EDITOR_PLAN_TESTS (off by default), compiles the interfaces a second time into a small library of its own, because a test can only import modules from a target it links and linking the game would drag the whole simulator in. The code under test needs nothing but a compiler. 7/7 pass. - a switch may now be written with two dashes as well: --editor beside -editor. Builds with clang 22 (-DWITH_BETTER_RENDERER=OFF); -editor and --editor both come up in the editor on empty ground.
