.redis_tooling_client ⇒ Object

Pooled rather than built per call - see Exercism::RedisPool for why.

.s3_client ⇒ Object

Memoized so the SDK's connection pool is reused, with a raised http_idle_timeout (default 5s) so pooled connections survive quiet spells on low-QPS paths instead of paying a TLS handshake each time. The mutex guarantees exactly one client per process.
