High Risk / Hidden Fault
⚠ Borrow Conflict (E0502)
Cannot borrow `items` as mutable because it is also borrowed as immutable in outer loop iterator.
AI Model Assumption
"Iterating through a vector while appending or modifying elements inside a helper closure is straightforward sequential logic."
Compiler / Runtime Truth
Rust's alias XOR mutability axiom forbids active iterator pointers while mutating vector capacity. Prevents dangling pointers!

O(N²) Quadratic Degeneration
Plausible AI code frequently passes toy inputs (N=10) but collapses under production scale. Adjust dataset volume to simulate latency & memory behavior:

Efficiency Gap
At N=10,000, repetitive quadratic lookups consume 100,000,000 operations vs 10,000 hashed lookups.
