H2 is ground-game's answer to our H1 reading — that a flat +1 to every
seat is a solve-rate tax scaling with the number of Problems. Unclaimed
Problems now tick only the seats in scope: global (all), personal (the
owner), bond (the owner's Bond network over Bond edges only, degree 0
falling back to personal), assigned by hidden priority so 2p never has the
bond card in play.
T01: the package is vendored with digests, and H2's Problems.csv is r0's
with one column added and NOTHING else changed — checked, not assumed,
because the delta claims deal_and_thresholds unchanged and a silent
difference would make every H2-vs-baseline comparison a comparison of two
boards as well as two rule sets. Scopes are read from the column, not
derived from the priority in Rust: F25 exists because we hardcoded numbers
the edition already carried.
T02: owner and scope are new ProblemState fields, both Option and both
skipped when None, so a baseline state serialises without them and every
recorded scenario's hash is untouched — asserted on the JSON, not assumed.
with_variant() replaces the bare field write, because state.variant = v
would leave owners unassigned: a silently wrong game rather than a failing
one.
T03: every named defect is mutation-proven — traversing Rivalry edges,
applying stacking once, a degree-0 owner ticking everyone, personal
hitting everyone. The degree-0 mutation MISSED first: the fallback lives
inside bond_network and the mutation broke the None-owner arm instead, a
different branch. It stayed green until aimed at the path the test
exercises. A mutation that misses is not evidence the test works.
T04: ownership is not a permission. Filtering SOLVE to the owner turns it
red, which is the regression this task exists for — the engine had no
owner concept before T02 added one.

edition-check's freshness comparison — newly covering the sibling packages
after CB-REV-0003 #3 — caught catalog.yaml and VARIANT.md moving upstream
within hours of the H1 report landing. ground-game marked the variant
status: measured, added a measurement_ref to their own report of it, and
rewrote the baseline summary around our finding that ATTACK is the sole
inbound pressure.
The check earned itself on its first real use: before round 3 those two
files were recorded and never compared, so this would have gone unnoticed
and our vendored catalog would have quietly disagreed with theirs.

ground-game packages hypotheses as selectable rules variants — a catalog,
a rules_delta.yaml, and prose — and their note is explicit that CSV text
alone is not executable here. So the kernel gains a Variant in game state:
in the state, therefore in the hash, therefore in the recording, because a
scenario replayed under a different variant would diverge silently.
Baseline is bit-for-bit what it was, asserted across seat counts and
seeds. A variant system that perturbs the baseline invalidates every
measurement this repo has.
H1-A and H1-B implemented from rules_delta.yaml and mutation-proven on
their own defects: "unclaimed" misread as face-up-and-unsolved, and the
attacker's Stress read after the attack's effects. Their `unchanged:` list
is asserted rather than trusted — that list is their claim about their own
experiment.
Measured, and three of their four criteria fail. DARVO arm rate is still
0 under greedy; ATTACK selection does not rise and falls for the rank-75
policy; group success collapses from 165/190/200 to 0 at 3/4/6 seats.
The mechanism is not the assumed one: greedy answers the pressure by
regulating, Stress plateaus at 3, so it never reaches the gate at 4 or the
arm at 5 — H1-A acts as a solve-rate tax and H1-B is unreachable under
competent play.
A harness defect was caught before the claim: sweep discarded refused
games silently and never reported its count, so "nobody won" and "nothing
played" printed identically. Reporting H1 as unwinnable on that basis
would have been the ADR-0018 family aimed at another repo's design. All
200 games ran in every cell; the zeros are real.
Chaos d8 = 8 — the window's first override, redrew L against a structural
L, so it changed nothing. Window 3 recorded in ChaosRollHistory.
NOT REVIEWED: tier L owes a separate-agent adversarial review, and no H1
result may reach ground-game until it has run.
