RustFS Scanner

RustFS Scanner is the background maintenance scan loop. It handles usage accounting, lifecycle expiry and transition admission, bucket replication repair admission, scanner-driven heal/bitrot checks, and namespace alerts.

For operator-facing runtime controls, status fields, and tuning workflows, see Scanner Runtime Controls. For repeatable scanner-pressure validation, see Scanner Benchmark Runbook.

Chinese documentation is available in README.zh-CN.md.
