Issue #44: code-register memory adapter with standing-context resource; fix dispatcher method-level Auth.Capability override (was always using verb-derived capability, ignoring per-method Auth field). Issue #45: per-backend bounded in-memory queue (VLLM_MAX_QUEUE_DEPTH=20) + concurrency semaphore (VLLM_MAX_NUM_SEQS=4); warmup requests (X-Poimen-Warmup: true) sleep WARMUP_DELAY_MS before queue entry; /metrics endpoint wired. Issue #46: rendezvous-hash backend selection on X-Poimen-Cache-Key; round-robin fallback; MarkFailed excludes unhealthy backends 30s; ModifyResponse captures vllm-num-cached-tokens + emits structured log + increments counter. Closes #44 Closes #45 Closes #46
