 ### Overview
 
 Hybrid quota management enables automatic detection of exhausted accounts and failover to next available account.
-When CCS detects exhaustion and a healthy fallback exists, it temporarily pauses the exhausted account out of CLIProxy rotation and automatically resumes that pause after the configured cooldown expires. This durable self-pause uses the same account registry and token movement path as dashboard/manual pause, so the dashboard shows the account as paused and CLIProxy cannot rediscover its token from the live `auth/` folder.
+Before local CLIProxy startup, CCS reconciles the whole active account pool for the provider, not only the default account. When CCS detects any quota-exhausted account and a healthy fallback exists, it temporarily pauses the exhausted account out of CLIProxy rotation and automatically resumes that pause after the configured cooldown expires. This durable self-pause uses the same account registry and token movement path as dashboard/manual pause, so the dashboard shows the account as paused and CLIProxy cannot rediscover its token from the live `auth/` folder.
