AIBotProfile carries the cosmetic metadata the AI rank-battle start
endpoint composes into oppo_info. BotRoster.Pick is deterministic per
MatchContext so mid-flight retries get the same opponent. ai_id values
4001..4008 are placeholders per the existing ai-start.md TODO — we have
no live capture of the prod catalog.
Future improvement: migrate Roster to a bot-roster.json seed under
SVSim.Bootstrap/Data/seeds/ for editability without rebuilds.
