// Phase 200-D: Minimal capture test (Pattern 2)
// This test verifies that captured variables work in JoinIR Pattern 2
// without using substring or other unsupported methods.
//
// Key points:
// - base/offset are captured (function-scoped constants)
// - No substring/indexOf in body-local init (Phase 193 limitation)
// - Simple accumulation using captured value
// - Break condition: i == 100 (never true, just to trigger Pattern 2)

static box Main {
    main() {
        local base = 10       // Captured var (used in multiplication)
        local offset = 5      // Captured var (used in addition)

        local i = 0
        local v = 0
        local n = 3           // Loop 3 times

        // Pattern 2: loop with break (break never fires)
        loop(i < n) {
            // Simple break condition that never fires

            // For i=1: v = 10 + 10 = 20
