Empirical Benchmarks & Replication Guide

This document separates mathematical derivations from hardware measurements. Below are the numbers captured on Apple Silicon and Chrome runtimes and the known measurement caveats.

1. Summary of Measured vs. Derived Values

Formula Compaction

4.1445×

Closed-form equation $W = \beta / ((1 - \alpha)(1 + f))$ against V8 expansion $\beta = 3.50$.

Ring Buffer Throughput

553,274 TPS

Single-threaded SPSC ring buffer replay.

2. Detailed Suite Results & Caveats

Benchmark Suite	What Was Measured	Observed Result	Scientific Scope & Caveat
Suite 1: Working Set Compaction	V8 managed heap memory bloat vs packed binary slab.	4.14× Model	Formula-derived from $\beta=3.50$, $\alpha=0.25$, $f=0.126$. Not a direct physical DRAM meter reading. Opaque blobs yield $W \approx 1.0\times$.
Suite 4: XPBD WebGPU Physics	Extended Position Based Dynamics shader round-trip.	2,635 Hz queue dispatch (measured on a 32-particle kernel with no collision stage; round-trip latency, not throughput)	Shader clamped at 32 particles / 96 edges (MAX_P=32, MAX_E=96). Measures queue roundtrip latency, not massive N-body stress.
Suite 5: Maglev Spine Partition Suite	Socket timeouts, breaker stamps, and partition recovery.	31 / 31 tests pass	Partition recovery under simulated link drops.

3. How to Measure It Yourself (Replication Guide)

B. Run the 31-Test Maglev Spine Partition Suite

Tests socket timeouts, breaker stamps, and partition recovery:

# Runs 31 unit and partition regression tests
node --test scripts/maglev-cluster-boot.test.mjs

# Expected output:
# ℹ tests 31
# ℹ pass 31
# ℹ fail 0
# ℹ duration_ms ~53,000ms

4. Falsification Criteria

Our research claims are defined to be strictly falsifiable under Popperian criteria:

Claim 1 (Compaction): Refuted if an adversary constructs a general-purpose V8 or JVM object graph with expansion $\beta \le 1.20$ while sustaining sub-millisecond continuous mutation without GC pauses $>1.0\text{ ms}$.
Claim 2 (Spine Bus): Refuted if an in-memory binary ring buffer fails to deliver sub-50 µs inter-agent dispatch on a unified-memory host without packet serialization.
