sample floor
An entity earns a descriptive card only after clearing a minimum-sample floor, so rates are not read off tiny samples. The floor for this pack is 30 real MLB franchises; AL/NL All-Star-Game placeholder codes excluded from the 32 raw team codes in the pull. team = PITCHING team, derived as home_team when inning_topbot=='Top' else away_team (defense is whichever side is not currently batting). no per-pitch swing/miss field in this pull (no `description` column; `type` merges called+swinging+foul into one S bucket, `des` only fires on PA-ending pitches) -- outcome mix (ball/strike/in-play) substitutes. Entities below the floor are deliberately left off -- we do not print rates we cannot stand behind.
