# Is w_u = 300 adequate at the SPEC's operating point, and how much margin is there?
#
# The spec section claims the window "never binds" (median reference lag 34 slots,
# max 197). The report puts a hard recovery floor at ~7/f = 210 slots, set by block SPACING rather than by
# delay, and advises widening to 450-600 near rho ~ 1. "Has margin at rho < 1" is defensible;
# "never binds" is not, and the difference is what this measures.
#
# absorption-window.yaml sweeps the same axis but starts at delta_max = 8; nothing has been run at
# the deployment's delta_max = 4. Since the floor is set by block spacing the knee should sit
# in the same place, which is itself worth confirming rather than assuming — the report's
# delay-invariance claim is exactly what makes a single recommended W defensible.
#
# U = 1 isolates the window: with more uncle slots the queue drains faster and the window stops
# being the binding constraint, which would mask the knee.
# Latency is in SLOTS (1 slot = 1 s).
