Experiments

Define every pre-registered experiment here (E1..E8 from VALIDATION_PROTOCOL.md).

Initial (bootstrap) experiments — all are NOT TESTED pending data+harness runs:

• E1 ARIMA > naive
• E2 SAX > naive
• E3 SAX adds info beyond ARIMA
• E4 ARIMA adds info beyond SAX
• E5 agreement improves conditional performance
• E6 disagreement identifies poor/unstable regimes
• E7 survives transaction costs
• E8 stable across walk-forward periods

Do not add model complexity until E1..E8 are answered.
