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.

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.

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.
