WASM objects used by brepjs are not tracked by the JavaScript garbage collector, so un-disposed shape and kernel handles cause silent, growing memory leaks that can crash browser-based CAD applications without warning.

brepjs WASM memory leaks occur because shape and kernel handles are invisible to JavaScript garbage collection, requiring explicit disposal calls to free allocated WebAssembly memory.
Debug unexplained memory growth by using getDisposalStats to identify missing disposal calls, peak handle accumulation, and FinalizationRegistry-reclaimed handles in your CAD application.
The best way to clean up WASM handles is using the using keyword, DisposalScope, and scoped helper functions to ensure deterministic disposal at the end of handle lifetimes.
occt-wasm arena memory is freed only via kernel dispose calls, whereas Embind kernel memory is freed directly via handle delete, causing leaks that appear on only one kernel.
Yes, you can enforce deterministic cleanup in CI by applying the require-using-for-handles pattern checker rule to verify all brepjs operations include proper handle disposal calls.
Audit brepjs operation code for missing handle disposal when writing new *Fns.ts operations or debugging unexplained memory growth to prevent silent WASM leaks that crash applications.
