Fetch the order in which the chain would deregister subnets to make room for a new registration -- 'how close is this subnet to being pruned', answered with the pallet's own rule. The network sits at SubnetLimit, so every new subnet registration evicts one. DO NOT ANSWER THIS BY SORTING moving_price. `Subtensor::get_network_to_prune()` skips root, skips every subnet still inside NetworkRegisteredAt + NetworkImmunityPeriod, compares `get_moving_alpha_price` -- which substitutes a FLAT 1.0 for a Stable (SubnetMechanism 0) subnet instead of reading SubnetMovingPrice -- and breaks a price tie on the EARLIER registration. Measured at block 8,808,300, a price-only sort names netuid 86, which reads a moving price of exactly 0 but is inside its immunity window and CANNOT BE PRUNED AT ALL, while the chain's answer is netuid 70; 16 of 128 subnets were immune. `ranked` holds prunable subnets only, rank 1 first -- that is the one the chain takes next. `immune` holds the protected ones, ordered by how soon protection lapses (the order in which they JOIN the ranking), each with `immune_until_block` and `blocks_until_prunable`; their `rank` is null because 'cannot be pruned' is not 'pruned last'. Every entry carries `comparison_price` (what the pallet compares) beside `moving_price` (the raw read), so the Stable substitution is visible. Errors rather than returning a body when the capture carries no pinned block or no immunity period, because an ordering computed without the immunity window is not an approximation -- it is a different ordering that looks identical.
