CB-WP-0042 T01-T04: H2's scoped stress, with the named defects caught
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.

# Experiment H2 — scoped problem stress (personal / bond / global)
| | |
|---|---|
CB-WP-0047: all four boards, and every mode named on the page
The modes were already implemented; nothing had ever COMPARED them. The
scenarios were not implemented at all: edition::deal has taken a
scenario_id since it was written and the only caller passed the literal
"SCN_01", so 15 of 20 Problem cards had never been dealt by anything.
The seam was the whole mechanism and it sat unused, with nothing red
because nothing asked.
Scenario is now state (serde default SCN_01, so all 26 recordings replay
unchanged), selected by preset `scn-03-4p` with `standard-Np` still
meaning SCN_01, and by --scenario/SCENARIO= accepting ids, numbers or
titles, validated against the edition rather than a pattern.
The threshold now comes off the Scenario card, closing F25's hardcoded
5/7/9. The first version of that control was worthless and mutation said
so: all four scenarios print 5/7/9, so reverting to the bands left it
green. Split threshold_from() so it can be handed a card that disagrees.
The header read `scoring CommonProblem` where the Mode card is titled
COMMON PROBLEM, PERSONAL EDGE -- the defect CB-WP-0034 deleted from the
move buttons, still standing on the line that says what winning means.
The coverage probe was matching that Debug output and went red when it
was fixed: third instance (CB-WP-0024, CB-WP-0034). Page now carries the
premise, the mode's rules text, and the tiebreak.
scenario-panel plays 4x3x3. Findings: SCN_01 and SCN_02 are the same
board (identical cells, pinned by a characterisation test); SCN_04 is
the hard board at 2p (52% vs 67/73%, the only deck needing two Repair);
and group success is EXACTLY equal across all three modes in all 36
cells, because greedy never reads state.mode -- filed F27, the two
competitive modes are scoring lenses over cooperative play.
F28: SHARED GROUND's mastery subtracts penalties from the claimed COUNT
where the mode card's shared score is claimed VALUE. Raised, not fixed;
scoring is ground-game's to rule on.
Also fixes design.py reporting a backticked path as no reproduction.

## Hypothesis
If unclaimed Problems apply End stress only to their **stress_scope** , with mostly personal, one bond at 3p+, and rare global (Surface), then some seats can climb toward DARVO **without** taxing the whole table into zero group wins — and **bond-scoped** cards give the Bond network a shared reason to SOLVE.
## Scopes
| stress_scope | End +1 Stress while unclaimed goes to… |
|--------------|----------------------------------------|
| **global** | every seat |
| **personal** | assigned **owner** only |
| **bond** | owner + every seat in the owner’ **Bond network** (Bond edges only). No Bonds → behaves as personal |
**SOLVE:** any seat with matching suit may claim any Problem (owner need not solve). Clearing a bond card is a network public good — that is intentional.
## Assignment in this package
By `hidden_priority` in `Problems.csv` :
| priority | scope | in play at |
|---------:|-------|------------|
| 0 Surface | global | all seats |
| 1 | personal | 2p+ |
| 2 | personal | 2p+ |
| 3 | **bond** | 3p+ only |
| 4 | personal | 5p+ only |
Owners: non-global in-play Problems, ascending priority, round-robin clockwise from **Lead** .
## Bond incentive (design intent)
Bond is still the regulation tool (− **spreads** cost across the network so partners are incentivised to clear *that* card together rather than leave one seat to melt alone. Measure whether networks SOLVE bond cards faster or avoid Bonding.
## Not in H2
- H1 flat global +1 for “any open problem”
- H1-B ATTACK self-soothe
- Owner-only SOLVE, shadow goals, competence track
## Simulation
Select `variant_id: h2-scoped-problem-stress` . Implement `rules_delta.yaml` (H2-SCOPE, H2-OWN, H2-A, H2-SOLVE). Compare to `ground-darvo-r0` and optionally `h1-problem-stress` .
