WASM MinCut module not available, using JS fallback

Error message

WASM MinCut module not available, using JS fallback

What it means

Fallback path in MinCutBridge.initialize(): the WASM min-cut module could not be loaded, so the bridge runs its pure-JS implementation instead. All downstream methods (findOptimalCuts, minSTCut, etc.) work but with reduced performance.

Solutions

1. Build/ship the WASM MinCut module and verify its load path so the native implementation is used.
2. Check WebAssembly support and required feature flags in the runtime.
3. If the JS fallback is intended, no action needed; it is slower but functionally equivalent.

When it happens

Trigger: The MinCut WASM module cannot be loaded or instantiated (missing artifact, unsupported runtime); bridge falls back to the JS MinCut implementation.

Common situations: See trigger scenarios.
