Author, build, or audit a native SKSE plugin DLL against CommonLibSSE-NG (alandtse ng) — "plugin" here means a compiled DLL, not an .esp or .psc — and load this before any SKSE C++ is written. Use for an SKSE plugin or .dll, declaring and registering a native Papyrus function, BSTEventSinks, game hooks (trampoline, Address Library), SE + AE + VR targeting, or reading someone else's SKSE DLL source. Multi-runtime and lifecycle rules compile clean yet fail at load.
