Worker slots live in separate namespaces (mapped lanes use worker-pool:slot:N, ordinary components worker-pool:comfy|llm:slot:N), each its own Modal container. Matching only the trailing slot:N gave the reserve cooldown to both the static comfy:slot:0 worker and mapped lane slot:0 in hybrid prompts, so reserve_cooldown_count=1 kept two idle GPUs. The planner now stamps one modal_reserve_cooldown_pool per Modal environment (mapped lanes when the prompt has mapped work, else comfy, else llm), and the lookup grants the reserve cooldown only to leading slots of that pool; every other worker uses the global cooldown.
