The last study still carrying pre-fix numbers. It was the most contaminated of
them — 2 of 8 replicates at alpha=0.3 and 1 of 8 at alpha=0.4 were running
majority coalitions — so it needed re-running before its levels could be quoted.
Every conclusion reproduces:
- alpha=0.3, delta=8: D-hat/D 0.757/0.769/0.775/0.766 across U=1..4 (was
0.729/0.755/0.738/0.758). Still flat in U — raising the cap does not buy the
estimate back, which is the section's point.
- No attacked cell reaches the 0.98 bar at any cap or either window.
- The honest baseline still reproduces §3.4 exactly: U=1 clears at delta=8;
delta=16 needs U=2 at W=10, or W=20 at U=1.
- The structural decomposition holds: countable share falls 97% -> 77% -> 54%
with alpha while referenced-of-countable stays high (70-92%), so the loss is
the first-fork restriction and not a drained queue.
§8.3 item 20 closes: every adversary study with the default selection has now
been re-measured, no conclusion was overturned, and the one materially resized
number was the parent anchor's cost under suppression (0.021 -> 0.006). What
replaces it is a residual worth stating rather than an open task — a Pareto draw
can leave adversary_frac unreachable outright, which now warns and leaves that
replicate with a weaker adversary than its label. That biases an attacked arm
toward the honest baseline, so it is conservative, but a sweep quoting levels
should report how many of its replicates warned.
