* s3api: recheck condition under lock when routed filer ignores condition_alt_key A filer that predates condition_alt_key silently drops the field and evaluates a suspended-versioning condition against the empty null slot alone, so a matching If-Match still gets a false 412. Recheck under the object lock instead of trusting that response: the lock path resolves the same entry the read path serves. Genuine precondition failures still return 412 from the recheck. * s3api: cover suspended If-Match against a filer ignoring condition_alt_key * s3api: resend against the resolved entry instead of the lock-path recheck Rechecking under the gateway object lock does not serialize against routed writers, which commit under the filer's path lock; a concurrent routed PUT could land between the recheck and the create and be overwritten with a stale precondition. Resend the same transaction with condition_key set to the resolved version file so the condition and the write stay under the same filer lock. When the resolved entry is the null slot, a delete marker, or unresolvable, the resend targets the object path and fails closed.
