What

tools/import_audit.py decides whether an import is served by a title module with library in modules, an exact file-name match. The relinker identifies modules by the name without its .prx, .sprx, .suprx or .debug_prx suffix, and on Windows ignoring case (GuestModuleBuilder.cpp ModuleStem, ImportModule.hpp ModuleSuffixes). A title whose eboot imports from EOSSDK-PS5-Shipping.debug_prx while the dump holds prx/eossdk-ps5-shipping.prx therefore gets every import reported as absent ("the loader fails") and exit code 1, although the converted title starts. ModuleNames now compares title module names by that stem, case-folded when the built libraries are Windows PE files; audit and the missing-library check use it unchanged. Two tests: a module file shipping.prx serves an import from shipping.debug_prx (CLI, JSON report class module), and ModuleNames folds case only when asked.

Overlap with #6171: measured on the same inputs, #6171 (SCE module identity) already turns the Coral-Island case from absent 236 into 0 (exit 0). This change covers the relinker's file-name rule (suffix ignored, case folded on Windows) for modules without a matching SCE identity; the CLI test (module shipping.prx, import from shipping.debug_prx) still fails with #6171 alone. I have no title evidence for that second case. Both change main() in import_audit.py (lines 731-733) and are independent; if the maintainers prefer one, #6171 first and this one rebased or closed.

Tested

Windows 10, WinLibs GCC 15.2.0 toolchain, Python 3.12: python -I tools/tests/test_import_audit.py passes (117 tests, 3 skipped); both new tests fail without the change (AttributeError: ... no attribute 'ModuleNames' and exit code 1 for the CLI case). Real data: the audit of one converted Unreal title (236 imports from EOSSDK-PS5-Shipping.debug_prx, module file eossdk-ps5-shipping.prx, Windows libs) reported absent 236 and exit 1 before, absent 0 and exit 0 after; the same title ran 560 s without a load error. A second title (Palworld, 289 such imports) had the same report. No title run for this change. tools/check_conventions.py --base upstream/main --head HEAD reports only the empty template sections.
