Carry restore context through POST status reads, metadata copy routing, null-version Object Lock checks and multipart completion. A failed read must preserve the target and must not enqueue its remote object for garbage collection. Cover initial/status POST failures and metadata loss during single and multipart rehydration on real disks.

Merge lock and tag revisions for duplicate versions before all-pool
lifecycle evaluation using the existing metadata reconciliation rules.
Distinguish ordinary lifecycle refusal from object absence and clear
rejected batch replication state so a late policy withdrawal cannot
schedule a purge. Preserve restored-copy cleanup and real absence.
Cover single and batch protections, legitimate metadata removals, and
actual replication queue and HTTP target behavior.

Reject replacement markers and legacy objects before restored-copy cleanup
can mutate their type or data. Prevent restore lookups and failure cleanup
from purging dangling versions, preserve Transition on metadata rereads,
and return without writing when the initial restore read fails.
Add real-disk regressions for stale null tasks, minority metadata, initial
and cleanup read failures, and stored marker/legacy types. Keep ordinary
dangling cleanup and marker purge as positive controls.

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.

Recheck only local ordinary-delete candidates that need an all-pool lifecycle decision. Match UUID/null identity to the version actually read and queue its global metadata and event; retain a successful read on recheck failure, absence, or refusal.
Keep GET reader cleanup, authorization, proxy reads, single-pool reads, restored-copy cleanup, and expiry response headers on their existing paths. Cover signed GET/HEAD, queue contents, metadata faults, missing matches, no-scan boundaries, and reader-lock release.

Availability-optimized writes can leave a readable null version across separate EC groups when a disk is unavailable. Recount ordinary null versions for all non-strict reads and cover version listing and complete pool removal with end-to-end tests.

Replace process-wide hash-slot mutexes with reference-counted locks keyed
by drive and path. Retain entries before waiting, acquire unique paths in
order, and reclaim entries only after all holders and waiters finish.
Add real storage API regressions for unrelated colliding objects and drives,
plus coverage for cancellation, multi-path order and waiter lifetimes.
