Function count_active_codes 

pub async fn count_active_codes(pool: &SqlitePool) -> Result<i64>

Count active, unexpired invite codes — the outstanding-but-unredeemed seats a bot has already promised. Added to count_beta_access this is the “seats committed” figure the bot mint path (POST /bot/claims) checks against the cap, so it doesn’t over-promise more claims than seats remain (the redeem-time cap in redeem_code is the hard backstop; this avoids telling a follower “you’re in” for a seat that will be full by the time they claim it).
