Ovidiu U	d13a29df01	docs: amend prediction rebuild spec with implementation defaults and changelog v3 ... Adds two sections to the spec: - Implementation defaults: pins the four open decisions settled before Phase 1 (naive baseline = zero-change, math = inline pure PHP, coefficients on the backtests row, BEIS retrain = manual CSV + cron) plus the namespace, scaler, and Pest conventions. - Changelog v3: records the verdict-via-rule-gates architecture (gates not multipliers), removal of weeks_since_duty_change as a feature, lower 62% backtest gate, structural leak detector promoted to primary. Captured here so a future session can resume implementation without re-deriving them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-03 08:39:26 +01:00
