// Phase 92 P2-3: Simplest P5b E2E Test (no body-local variables)
//
// This test uses position-based checks instead of a 'ch' variable
// to avoid the body-local variable complexity for initial testing.
//
// Pattern: Loop with break check + conditional increment (P5b escape pattern)
//
// Expected behavior:
// - i=0: not quote (0!=4), not escape (0!=2), i=1
// - i=1: not quote (1!=4), not escape (1!=2), i=2
// - i=2: not quote (2!=4), IS escape (2==2), i=4
// - i=4: IS quote (4==4), break
// - Output: 4
