+//! Request body size limits for admin API endpoints
+//!
+//! These limits prevent DoS attacks through unbounded memory allocation
+//! while allowing legitimate use cases.
+
+/// Maximum size for standard admin API request bodies (1 MB)
+/// Used for: user creation/update, policies, tier config, KMS config, events, groups, service accounts
+/// Rationale: Admin API payloads are typically JSON/XML configs under 100KB.
+/// AWS IAM policy limit is 6KB-10KB. 1MB provides generous headroom.
+pub const MAX_ADMIN_REQUEST_BODY_SIZE: usize = 1024 * 1024; // 1 MB
+
+/// Maximum size for IAM import/export operations (10 MB)
+/// Used for: IAM entity imports/exports containing multiple users, policies, groups
+/// Rationale: ZIP archives with hundreds of IAM entities. 10MB allows ~10,000 small configs.
+pub const MAX_IAM_IMPORT_SIZE: usize = 10 * 1024 * 1024; // 10 MB
+
+/// Maximum size for bucket metadata import operations (100 MB)
+/// Used for: Bucket metadata import containing configurations for many buckets
+/// Rationale: Large deployments may have thousands of buckets with various configs.
+/// 100MB allows importing metadata for ~10,000 buckets with reasonable configs.
+pub const MAX_BUCKET_METADATA_IMPORT_SIZE: usize = 100 * 1024 * 1024; // 100 MB
+
+/// Maximum size for healing operation requests (1 MB)
+/// Used for: Healing parameters and configuration
+/// Rationale: Healing requests contain bucket/object paths and options. Should be small.
+pub const MAX_HEAL_REQUEST_SIZE: usize = 1024 * 1024; // 1 MB
+
+/// Maximum size for S3 client response bodies (10 MB)
+/// Used for: Reading responses from remote S3-compatible services (ACL, attributes, lists)
+/// Rationale: Responses from external services should be bounded.
+/// Large responses (>10MB) indicate misconfiguration or potential attack.
+/// Typical responses: ACL XML < 10KB, List responses < 1MB
+///
+/// Rationale: Responses from external S3-compatible services should be bounded.
+/// - ACL XML responses: typically < 10KB
+/// - Object attributes: typically < 100KB
+/// - List responses: typically < 1MB (1000 objects with metadata)
+/// - Location/error responses: typically < 10KB
+///
+/// 10MB provides generous headroom for legitimate responses while preventing
+/// memory exhaustion from malicious or misconfigured remote services.
