Overview

Kimi-K3 sets VLLM_PREFIX_CACHE_RETENTION_INTERVAL and VLLM_RPC_TIMEOUT, which no longer exist in vllm/envs.py, so vLLM silently ignores both.

Claims

• Drops both envs from every env block, guide export line and runbook env list.
• No behaviour change: --prefix-cache-retention-interval already defaults to 0, the value set here, and nothing reads VLLM_RPC_TIMEOUT.

Validation

grep -c 'VLLM_RPC_TIMEOUT\|VLLM_PREFIX_CACHE_RETENTION_INTERVAL' vllm/envs.py  (main) → 0
grep 'prefix_cache_retention_interval:' vllm/config/cache.py                  (main) → default=0
node scripts/validate-source.mjs --source vllm --dir recipes  (vllm-project/recipes) → valid
Kimi-K3 generated JSON: RPC_TIMEOUT 3 → 0, RETENTION_INTERVAL 5 → 0; VLLM_USE_DIRECT_DCP_A2A 9 → 9 (control)

Details

Not served; the check is config-level only.
