checkSSECCopySourceKey duplicated the source-key authentication that both
CopyObject read paths already perform; the DeleteObjects signature-error
branch became unreachable once signatures are verified once per request; the
discrete PostgreSQL and MySQL notification environment constants have had no
reader since DSNs became mandatory.

The pre-authentication CORS lookup stays resident-only, so client-supplied
path segments still cause no metadata I/O and no cache growth. The
fail-closed states for startup, load failures, and the internal namespace
are gone: CORS is a browser response policy rather than an authorization
boundary, and failing closed only denied browser clients CORS headers while
bucket metadata was still loading. A bucket whose stored CORS document does
not parse still gets no CORS headers. This removes the loadFailed bookkeeping
and the unused GetCorsConfig, HasAllowedOrigin, and generic Update path for
CORS; tests use the CORS-specific writer.

Site adoption and ForceCreate preserved a suspended or prefix-excluded
versioning configuration while bootstrapping Object Lock, persisting a state
that PutBucketVersioning itself rejects: objects under an excluded prefix in
a WORM bucket were not versioned and escaped retention. enablePeerBucketVersioning
now takes the lock intent and replaces such configurations with plain Enabled
versioning, and metadata loading ignores prefix exclusions on a locked bucket
as it ignored suspension before. The adoption tests assert the normalized
state and keep the timestamp-preservation checks on valid documents.

A request that does not earn replication trust continues with a clone whose
internal replication headers are removed. r.Clone copies the Trailer map, but
the streaming body reader created from the original request fills the
original map, so a trailing checksum was never seen by the hash reader and
PutObject and UploadPart with STREAMING-UNSIGNED-PAYLOAD-TRAILER failed with
XAmzContentChecksumMismatch whenever an untrusted X-Minio-Source-* header was
present. Share the trailer map with the clone, as the Snowball path already
does for its per-entry requests, and cover both handlers with a test.
The marker evaluation that was copied into six handlers now lives in
evaluateReplicationTrust so the rule (a declared replica without the
replication permission is rejected; trust needs the exact marker plus the
permission) is defined once.

GetObjectAttributes lets a replication peer read SSE-C attributes without
presenting the customer key. That carve-out was keyed on the
X-Minio-Source-Replication-Request header alone, which any client can set,
so a caller holding only s3:GetObject could read an SSE-C object's ETag,
plaintext size, part list, and checksums without the key -- the response was
byte-identical to one made with the correct key.
Gate the carve-out on s3:ReplicateObject for the target object, mirroring
CopyObjectHandler's existing replication check.
The pre-existing test asserted the carve-out with root credentials, which
hold every action and therefore cannot tell a gated check apart from an
ungated one. Add least-privilege cases that do: a reader without
s3:ReplicateObject is now refused, a caller that holds it keeps the
carve-out, and the ordinary key-bearing path is unchanged.
