The pattern is now measured over three rounds: 5 fatal, then 3 (2 from the
previous round's corrections), then 4 (3 from them). The corrections are
not getting safer.
FATAL 1: round 2's short-cell assertion went into regulation.rs only.
attack-value.rs — which produced every number in CB-EV-0030's DARVO table
— still just warned, and the gate registered to close the finding claimed
the property for both.
FATAL 2, the sharpest of the three rounds: counting games proves they
STARTED. Stopping the engine after one round gives 200 games, all-zero
columns and exit 0 — byte for byte the signature CB-EV-0030 says the
instrumentation distinguishes from a real result. Both harnesses now
require every counted game to have reached an outcome over five rounds.
FATAL 3: round 2's `.csv` filter was applied to all three loops, so
catalog.yaml and rules_delta.yaml — whose missing digests were round 1's
finding — were recorded and then never compared, and never checked against
upstream at all. Only the parser loop filters now.
FATAL 4: five of six tiebreak comparators had no coverage. GR-E04's
tiebreak never executes in any scenario. All four are now covered and
mutation-verified; the Blame key needed compensating claims to be
reachable at all, since Blame also lowers the coalition score.
SERIOUS: "peak held" computed the same number as "peak assigned" for every
possible input — the real gap was that START_STRESS was an unchecked
constant, now read off the dealt state; cadence="none" was a pure
loophole, removed; sibling discovery swapped a hand-written list for
hand-written globs and missed metadata.json and VARIANT.md, both named in
the package's own changed_files — now walked, and it found them
immediately; and "~72,000 games" was unsourced, make panels runs 17,600.
Also separated two kinds of number that were presented alike: seats×games
is invariant, 363 and 29 vary 7.1%-11.5% across samples.
Round 4 owed. The conclusion is not that the work is nearly right — it is
that author-made corrections to measurement work should be assumed
defective until a fresh reader has attacked them.

Three FATAL, five SERIOUS. The substance of round 1's corrections held —
Reactive is genuinely one arm different, the five replacement controls are
non-inert, the inert metric is right, the numbers reproduce. What failed
were the CLAIMS about them, and two defects the corrections introduced.
FATAL 1: the fix for round 1's #11 did not fix it. The assertion was
`games + setup_fails == 200`, and a refused setup increments setup_fails
while skipping games — so the sum is invariant under exactly the failure
it claimed to catch. Injecting setup failures gave exit 0 over 196-game
columns. Now asserts games == GAMES, verified to exit 101.
FATAL 2: the correction to the selective-column FATAL was itself
selective. "81-1000 per cell, baseline AND H1" and "31-1000" twelve lines
apart, both taken from the baseline row; under H1 rank-75 arms are
59/0/0/0. Every cell is now printed rather than summarised, and the
corrected verdict is the opposite of the one it replaced: under rank-75,
H1 REDUCES DARVO arms to zero at 3p and above.
FATAL 3: "DARVO arms 2 per seat per game" is 1 per seat per game, exactly,
at every band.
SERIOUS: the tiebreak oracle asserted only that the winner set CHANGED, so
reversing the tiebreak left it green; the #13 defect's impact was claimed
and never measured (72,000 games: zero divergences — real in principle,
witnessed only by a constructed board); a 29-of-363 citation pointed at a
file that did not contain it (round 1's reviewer did report it, and it was
never transcribed — the record was wrong, not the number); the harnesses
were run by NO GATE, so every published figure came from a manual run of
an ungated binary, including the assertion added for #1; and edition-check's
sibling handling — added by the last correction — was self-certifying,
crashed instead of failing, and counted Markdown lines as coverage. Now
discovered on disk, and it found a real gap on its first run: Rules_Text.csv
vendored with no digest.
Also: "peak Stress held" was dead code kept quiet by `let _ = held;` — the
numbers were right by coincidence.
make panels is now a registered gate. Round 3 is owed.

H1-B on the DARVO extra Attack: the delta says the extra Attack shares
the Attack resolution "so it can self-soothe too if Stress >= 4".
CB-WP-0038 asserted it because the code shares resolve_attack; nothing
tested it, and CB-EV-0031's withdrawn mechanism story ran through that
exact path. Now tested and mutation-verified.
Round-5 pressure did not reach the score, and this was a real defect
rather than a reporting one. end_round_events scored from `self` while
H1-A's pressure went into `work`, and score() reads Stress for the GR-E03
and GR-E04 tiebreaks — so the final round's pressure was invisible to the
two modes CB-EV-0030 reports on. Fixed. The test uses the case that bites:
uniform pressure preserves an ordering, so it takes the clamp at 5 to
collapse a gap and change who wins.
Inert arms reported separately: a DARVO arm at the End of Round 5 can
never advance a stage, and criterion 1 is about DARVO mattering. 29 of 363
at 2p, none above — matching the reviewer's independent figure, so
criterion 1 stands as met.
That fix produced one more wrong-subject error, caught before reporting:
the first inert-arm metric tested `g.rounds >= 5`, a property of the GAME
rather than the EVENT, so it marked every arm in every completed game
inert and briefly read as "criterion 1 fails after all". An arm is inert
when no RoundEnded follows it.
regulation.rs no longer skips setup failures silently: they are counted,
and a short cell fails an assertion rather than printing a number a reader
has to notice — which is the credit CB-EV-0030 §3 took and half earned.
All thirteen challenges closed. Re-review is owed before any of this
travels: the corrections were made by the author of the errors.

Thirteen challenges, five FATAL, all five conceded. Nothing had reached
ground-game, which is the only reason this is a correction and not a
retraction.
The worst: `Reactive` was not "greedy with one preference changed". It
differed in five, including SpendFreedom — ranked 95 unconditionally
against greedy's `95 if gated else 0` — so the seat burned its Freedom
token in round one of every game. A second change to the exact mechanism
under study, and every number in CB-EV-0031 was measuring it. The pass
claimed ADR-0018's one-varying-parameter discipline in its own workplan
while violating it. GreedyPolicy::rank is now public and the policy
delegates, overriding one match arm, so the control is structurally true.
Withdrawn entirely: "H1-B suppresses DARVO in the attacker". Disabling
H1-B under the corrected policy changes the arm count by exactly zero.
The pass hedged the wrong variable — it disclaimed "the number 2" and
defended "the direction", and the direction is what failed. The
supporting inference was invalid anyway: final Stress cannot show who
armed, because DarvoEnded resets the stage and REVERSE gives its owner -2.
Corrected: criterion 1 was failed on the greedy column while the pass's
own printed table showed 31-1000 arms in the other columns — the
selective-column move, in the file that names it. "Peak Stress was 1" was
a maximum over StressSet payloads, not held state (true: 2); the baseline
game count was 1,600 not 3,200; and "a reckless policy plays identically
to a careful one" is refuted by this repo's own rank-95 policy.
Inert controls replaced, each verified red against the reviewer's own
mutation: the baseline hash test compared two identically-constructed
states (serde(skip) on variant left 57/57 green); the `unchanged:` test
checked 3 of 7 entries and passed with SOLVE made illegal; H1-A's ordering
and H1-B's OU-cancel path had no test at all.
edition-check now covers catalog.yaml and rules_delta.yaml, whose digests
CB-WP-0038 claimed and never recorded — the review found it and reported
it unverified rather than absent, which was the right call.
Still open: H1-B on the DARVO extra-Attack path is untested, regulation.rs
still skips setup failures silently, and round-5 arms are counted though
they can never act.
