The Modal Configuration node gains three advanced widgets:
- global_cooldown (default 60s): idle scaledown for every Modal worker.
- reserve_cooldown_count (default 0): how many worker slots use the reserve
cooldown; must not exceed instance_count.
- reserve_cooldown (default 300s): idle scaledown for the reserved slots.
The policy travels on remote payloads and is applied per call with
Cls.with_options(scaledown_window=...), keyed by the worker-pool slot parsed
from the affinity key. Slots below reserve_cooldown_count stay warm longer;
other slots and unslotted keys use the global cooldown. Local-gap pools still
keep at least the local keepalive window. The fields do not shape the runtime
fingerprint, but derived payloads (warmups, prewarm targets, mapped phases)
inherit them so they land in the same container pool.
