pub const DEFAULT_BUFFER_HORIZON_EPOCHS: u32 = 4;Expand description
The horizon, in future epochs, a node covers when it recommends a buffer without being told
otherwise — 4.
Published on the contract so a client can recognise the ordinary case, NOT so it can assume one:
the horizon a node actually used always travels in
CollateralBufferResult::Known, and a reader
that substituted this constant for a payload it failed to read would state a claim the node
never made.
Four epochs bounds the compounded escalation ceiling at roughly x1.60. Fewer leaves a node one
bad epoch from dangerously_low; many more prices in a x4.62 worst case the controller reaches
only by escalating every single epoch, and locking $DIG against it has a real opportunity cost.
