backlog#1823 step 1, the diagnosis half. Temporarily removing set_disk/mod.rs's #![allow(unused_variables)] surfaced nine bindings. The issue asks that values computed and then dropped on write/quorum paths be diagnosed before being underscored, and that turned out to matter: only four were plain leftovers. Two errors were bound and then left out of the log they were bound for. complete_multipart_upload's checksum failures read `if let Err(err) = ...` and then log part_id, bucket and object with no `err` anywhere in the message, so a checksum failure in production told you which part failed but not why. Both messages now carry the error. One is a lock guard. heal's write_lock_guard holds a namespace write lock for the rest of the scope; renaming it to a bare `_` would drop it immediately and release the lock. It is now `_write_lock_guard`, with a comment saying why it must not be `_`. One was kept alive by a corpse. `errors` in read_multiple_files is read by nothing except two commented-out debug! lines directly below it; the binding and the commented lines go together. One is a cfg split. heal's disk_index is read only inside the #[cfg(test)] fault-injection branch, so underscoring it would break the test build; a `#[cfg(not(test))] let _ = disk_index;` covers the non-test lane instead. The remaining four are genuine leftovers: an unused enumerate index in list_object_parts, a discarded error in a heal reader loop, an inner binding shadowing its own iterator variable, and delete_object's write_quorum. That last one is worth a separate look: delete_object asks get_object_info_and_quorum for a write quorum and never uses it, because delete_object_version below recomputes its own as disks.len() / 2 + 1. The two are not the same number — one comes from the object's erasure configuration, the other is a plain majority of the disk array. Pre-existing behaviour, untouched here. The blankets stay for now. Removing #![allow(unused_imports)] exposes 76 unused imports in set_disk/mod.rs, and they cannot be removed per-lane: cargo fix, working from the lib lane, produced 54 compile errors in the test lane. That needs its own pass with both lanes checked per import. Verification: cargo check -p rustfs-ecstore --tests and --features test-util --tests both warning-free; clippy --lib --tests -D warnings clean; cargo nextest run -p rustfs-ecstore 4101 passed; make pre-commit exit 0. Ref rustfs/backlog#1823 (step 1).
