[Alex R (alexr17)]

Loop Runtime defaults to one steady-state pod and brings up one ready replacement before draining the old pod during rolling updates.
Explicit replica overrides remain supported, including values retained during upgrades; one replica provides less redundancy during unexpected pod or node failure.

Input	Behavior
Enabled on Google Autopilot or Standard; default or missing replica override	One pod; rolling update allows one surge pod and zero unavailable pods.
Null or empty replica count	One pod.
Explicit zero	Scaled to zero.
Explicit positive replica count, including a retained count of two	Count preserved; rollout uses the same surge settings.
Disabled, including a missing loopRuntime map in reused values	Runtime resources omitted; enabling and disabling retain the existing gates.
Reused values that predate Loop Runtime, then partially enable it	Existing guidance to use --reset-then-reuse-values remains.
AWS or Azure	Disabled by default; enabling Loop Runtime retains the existing Google-only validation.
Release tags with or without v, full or short SHAs, numeric SHAs, prerelease and custom tags	Image tags pass through unchanged.
