Wire the three production delivery points, each a single non-blocking try_send next to the existing in-memory heal paths, which stay as the fast path: - read.rs decode-error branch: DecodeFailure intent beside the existing read-repair submit, so an Urgent ECDecode request survives restarts even when the Low-priority read-repair request was dropped or lost. - add_partial: PartialWrite intent, giving partial-write recovery a durable Normal-priority object heal across restarts. - scanner_folder metadata-corruption classification: MetadataCorruption intent beside the existing High-priority scanner heal request. All three are on error paths only: zero cost on healthy IO. Part of backlog#1865 (option a). Co-Authored-By: heihutu <heihutu@gmail.com>
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.
