Section 5.3 of 05-rating-boosts.md described profile-based boost
distribution (power/contact/patient hitter profiles) that was never
built. Updated to document the actual shipped algorithms: fixed column
deltas for batters and TB-budget priority drain for pitchers, both in
database/app/services/refractor_boost.py.
Corrected the truncation behavior — the implementation scales positive
deltas proportionally rather than discarding them, preserving the
108-sum exactly in all cases.
Updated REFRACTOR_PHASE2_VALIDATION_SPEC.md T4-1 to reflect shipped
function signatures and marked the case as complete.
