How exposed a subnet is to being removed from the network. A subnet is only ever removed when someone registers a new one while the network is at its cap, and the victim is the surviving subnet with the lowest price EMA.

Immune subnets cannot be removed at all and carry no rank. A subnet whose owner never called start_call has a price EMA frozen at 0, which puts it at the very front of the queue the moment its immunity ends. The bands are a presentation choice, not a chain concept: on-chain, only rank 1 means anything, and since registrations have historically arrived about weekly the rank reads roughly as weeks of headroom. The envelope `dereg_context` tells you whether the network is actually at capacity, and none of this matters while it is not.

A grace period after registration during which a subnet cannot be deregistered, whatever its price.

The comparison is strict, so the subnet becomes prunable exactly on its end block. The fields are only set while the subnet is actually immune. The window length is a chain parameter, served alongside as `immunity_period_blocks`.

The value the chain compares when it has to pick which subnet to remove: the same smoothed moving price shown elsewhere, not the spot price.

Using the EMA rather than spot is deliberate: it makes the choice unforgeable by a single trade. A subnet that never started emission sits at 0 and is therefore always the first candidate.
