Contract 7.1.17

Training days are race-week days like the war days (Jamie, 2026-09-24): a member plays the same four war decks all week; on a war day each can be played once and scores, and training days are reps with them.

• The record keeps one row per member per day of the race week, training days included; nothing a tool serves changes shape.
• war_current.training_today and war_history.member_weeks[].training_decks say they are the war decks played on training days, not a separate practice count.
