Keep the storage layer error precedence for missing buckets and uploads while retaining every real upload lock. Cover the alias with short deadlines and race-check the original complete-multipart suite in CI.

Preserve handler version context, resolve the requested version's pool, and
return on the initial read failure without writing metadata. Propagate owned
NoLock to single-part writes, multipart completion and failure cleanup in
the same patch. Preserve the original modification time on cleanup.
Route the restore status copy by version and allow internal multipart
rehydration only for a matching completed transition. Single-pool restores
own the metadata snapshot through download and cleanup. Keep public
completion in object-before-upload order, using the target set's object
lock for single-pool calls, so concurrent completion cannot invert locks.
Cover real signed POSTs, null/UUID and cross-pool identity, download failures,
multipart overwrite guards, Object Lock updates and concurrent completion.
This package depends on the restored-copy cleanup safety delivered in R2.
