Add a default-off inline-only data-read metadata early-stop gate that verifies inline plaintext before cancelling pending metadata tasks. Keep non-inline, prepared, and request-shape-sensitive reads on full fanout, and record scheduled/completed/cancelled ReadVersion lifecycle metrics for normal fanout completion.

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.
