Evaluate conditional multipart initiation against the logical current object across pools while retaining pool routing and holding the object lock through upload placement.

The merged all-pool check from #279 decided on the versions that a read
quorum of each set merged non-strictly. A drive that missed one metadata
update could therefore supply the revision used for the decision, and a
partially unreadable set could drop a committed version from the history.
Both let an expiry delete data the rule did not cover, including a version
under legal hold.
- objectVersions accepts a revision only when max(n/2+1, the version's
metadata read quorum) drives hold it, identifies revisions by the header
plus a sha256 over a canonical, length-prefixed encoding of the
normalized metadata, filters non-accepted revisions before the strict
merge, and fails closed on omitted versions, too many unreadable drives,
or cancellation.
- Lock fields are read with the evaluator's key precedence. Cross-pool
copies that disagree on hold or retention must be strictly ordered by
valid timestamps; copies with different ModTime are separate writes and
an older protected write refuses the object. The set safeguard re-checks
protection and pending purges on its fresh read for checked version
deletes.
- Duplicate copies with semantically different replication or purge state
refuse the object.
- Batch expiry announces and audits only completed or already-absent
removals.
Reviewed adversarially over seven rounds; the final round approved with no
remaining findings in scope. All-versions expiry through deletePrefix and
tiered delete-all dispatch are tracked separately.

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.

Reuse deleteObjectReconciled for tiered bulk entries and unversioned single deletes. Its reference-aware cleanup avoids scheduling remote contents for garbage collection while another copy still needs them, including restored copies. Keep the normal local-data bulk path unchanged.
Extend existing tier GC regressions to bulk and unversioned deletes and include them in the multi-pool race CI step.

Resolve each addressed version under the shared write lock, keep bulk I/O parallel within cleanup and authoritative-deletion stages, and preserve replication response identity on errors. Treat reliable absence as successful physical cleanup on retries without accepting it for marker or replication-state writes.
Cover execution-time faults, partial cleanup recovery, mixed authoritative pools, response identity, null marker ordering, metadata uncertainty, cancellation, and concurrent PUT. Run the delete consistency regressions under race in CI.

Move solitary and null delete markers instead of dropping them, including
idempotent UUID marker retries. Check that a reader's source version still
exists before moving it, and preserve the established read winner for
conflicting timestamp ties.
Retire only the versions that were successfully moved while holding the
pooled object lock. Recheck the source and retained copies before cleanup,
so concurrent deletes and uncertain destination reads cannot revive data.
Count remaining markers when verifying decommission completion.
Add two/three-pool walker, history, purge, concurrent-delete, read-fault,
and timestamp-tie regressions.

Require write-quorum absence for missing purge retries, aggregate removed and already-absent votes only for physical purges, and resolve receiver purges by version across pools. Preserve marker metadata through creation and healing while retaining DELETE response semantics.
Add real-disk quorum, pool, callback, metadata, heal and outbound replication regressions. Synchronize capacity fixture installation and restoration with concurrent IAM readers.

Persist, send and reconcile empty tag states together with their revision
across COPY, PUT and multipart replication. Advance local tag mutations
under the existing locks and preserve current tags during replication ACK.
Cover signed HTTP, persistent single/multiple pool state, KMS, SSE-C key
rotation, ordering, retry and duplicate requests. Record real Opus plan
consensus, implementation review and local verification evidence.

Delete every copy of an explicitly addressed UUID, null version or delete
marker under the pool lock. Preserve retention and replication callbacks,
report unreadable pools and cleanup failures, and keep movement, incoming
replication, expiration and free-version cleanup on their existing paths.
Retain the separately developed general DELETE repair and replace its
access-mover-only coverage with a real interrupted rebalance copy followed
by HTTP deletion. Cover unqualified directory-marker DELETE and document
the existing pool-order-dependent 503 behavior that this makes consistent.
