Priority-preserving busy-week compression — not a flat percentage cut. Total working sets are ~78% of the 4-day plan (~67 vs ~86). Per-muscle floors are selective: protect priority stimulus, trim lower-priority isolation categories.
Near full 4-day floors: Chest 8 · Side 6 · Front 2 · Tri 10 · Quads 8 · Calves 8 · Core 4 · Thickness 4. Reduced: Bi 7 · Hams 7 · Traps 2 · Rear 2 · Add 2. Width 6 (slightly higher from frequency). Live lists after v48 seed.
Rules: compounds default 2 · no shoulder press (front raise on FB1) · standing calves only · dual tri across the week · Bayesian earlier on FB2 · optional loaded stretch after last OH tri or Bayesian · defined stall before any 3rd compound set.
