# Does the SPEC's uncle-selection rule move the window floor? (§3.4, §8.3 item 11)
#
# Every window result in the report fills uncle slots OLDEST-FIRST, and the ~7/f floor is derived
# from exactly that: an orphan queue drained one per block interval. The spec selects with an
# unbiased per-candidate coin instead (uncle_random_p = 0.5). §3.4 argues a coin drains a queued
# orphan no faster than oldest-first, so the floor under it can only be the same or higher, and
# reads the margined W = 10/f as covering the difference. That argument has never been measured.
#
# This sweeps the window absorption parameter under BOTH selection rules at the two delays that
# bracket the design regime (rho ~ 0.6 and rho ~ 1), and asks one question: does the recovery knee
# move, and does W_abs = 10 still clear?
#
# UNPAIRED by construction: uncle_strategy is part of the RNG identity, so the two arms draw
# independent stake, graph and lottery streams — and unlike the countable-vs-old comparison there
# is no way to share them, because the coin arm consumes draws the oldest-first arm does not.
# Note the §9 negative-control idiom is NOT available here: SweepConfig.expand() collapses U=0
# across uncle_strategy (with no uncle slots the two arms would be the identical run), so there is
# no U=0 gap to read a noise floor off. Resolution comes from the replicate SEM within each cell
# instead, which is why this runs 10 replicates against absorption-window.yaml's 5. U=0 is still
# carried as the recovery baseline the knee is measured against.
# Latency is in SLOTS (1 slot = 1 s).
