Athenum Analytics — BTC/ETH return-baseline comparison, v1, 24 September 2026
https://www.athenum.xyz/research/bitcoin-ethereum-baselines/

Unzip all files together. Requires Node 22 and internet access:
  node reproduce.mjs ./results
This fetches public Binance BTCUSDT and ETHUSDT perpetual hourly candles,
validates both series and writes hourly-statistics.csv and summary.json.
analysis.mjs is the pure calculation module; keep it beside reproduce.mjs.

Optional independent Python 3 verification (standard library, 40-digit Decimal):
  RESEARCH_PRIVATE_RAW_DIR=./raw node reproduce.mjs ./results
  python3 verify.py ./raw ./results/summary.json
Raw responses are for local verification. They are not in this bundle.

Rates: percentage points. UTC close boundary = candle open time plus one hour.
Primary tie tolerance: 1e-9 percentage points. Sensitivity threshold: 0.01 pp.
Missing prices are errors. Midnight ties remain in the headline denominator.
The sample covers 2025-09-22 09:00 through 2026-09-22 08:00 UTC, inclusive.
