Create policy and CORS state, force-create the existing bucket, and require the original Created time and both metadata fields to survive.

Use one per-bucket metadata.lock for ordinary updates, CORS transitions, and legacy bulk replication. Persist and update the local cache while locked, then release before peer metadata reload fan-out.\n\nRefs: #102

Pause one whole-record writer at the metadata PutObject boundary and let a different config writer commit from the same stale snapshot. Assert that policy+CORS and tagging+SSE both survive on disk and in the resident cache.

Authenticate DeleteObjects before validating entry count, remove the obsolete per-version auth helper, and pin the marker-only request to the ordinary authorization path.\n\nRefs: #58

Document that replication targets retain the DeleteObject plus ReplicateDelete contract and extend the existing two-site test with a target user that lacks DeleteObjectVersion. Use mc for explicit version deletion so the gate no longer depends on AWS CLI.

Select DeleteObject or DeleteObjectVersion from each request's effective version ID for single and multi-delete. Authenticate multi-delete once, bind version conditions to each XML entry, and keep the established DeleteObject plus ReplicateDelete target contract with explicit version denies honored only on trusted replication.\n\nRefs: #58

Prove that DeleteObjectVersion-only principals cannot delete named UUID or null versions while DeleteObject-only principals can, contrary to the S3 action mapping in issue #58.

Snapshot per-entry requests after applying bucket encryption defaults but before streaming trailers are consumed. Keep authorization failures fatal while retaining Snowball ignore-errors behavior for object-lock failures.

Place synthetic permission-check objects under each enabled rule's effective prefix, so least-privilege target policies are validated against the namespace they will actually replicate.

Evaluate PutObject and ReplicateObject permissions with immutable per-entry request snapshots during concurrent Snowball extraction. Preserve the first API error without sharing mutable handler state, and cover prefix-scoped trust under the race detector.

Evaluate ReplicateObject or ReplicateDelete before returning the no-op validation response, so underprivileged target credentials fail during replication setup instead of at runtime.

Count only valid live CORS states in per-site summaries. Treat baselines and tombstones as absent, and diagnose malformed payloads or missing source timestamps.\n\nRefs: #77
Signed-off-by: Feng Ruohang <rh@vonng.com>
Keep pre-authentication CORS lookups resident-only so attacker-controlled path segments cannot trigger metadata I/O or grow the metadata cache. Preserve fail-closed behavior for startup, load failures, invalid metadata, and the internal namespace.
Centralize replication request trust after authentication, distinguish general replication from replica-only privileges, and gate SSE-C ciphertext handling, source metadata, object-lock bypasses, event suppression, delete semantics, and replica status on the appropriate permission. Add least-privilege, multipart, PostPolicy, CORS amplification, and compatibility regressions.

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.
