ContiguousMap and InsertionOrderMap report a null key in Contains/Remove(KeyValuePair) and the IDictionary constructors with ParamName "key", where OrderedMap reports "item" / "dictionary"

A comparer that throws during ContiguousSet/InsertionOrderSet IntersectWith, ExceptWith or SymmetricExceptWith leaves a duplicated element and loses another

ExceptWith(set.Where(...)) removes one element, then throws "Collection was modified" and leaves ContiguousSet/OrderedSet/InsertionOrderSet half-changed

foreach over ContiguousCollection/ContiguousSet/ContiguousMap/RingBuffer is 3–4x slower than List/Dictionary and allocates every loop, because GetEnumerator is a boxed iterator method

OrderedSet/OrderedMap have no Min/Max or positional access, so set.Last() walks all n elements (~2.4 ms on a 1M set) where SortedSet.Max is O(log n)

SpscRingBuffer and DelayLine have no benchmarks, though the benchmarking plan requires one per container and marks coverage as complete
