d30938b259 CB-WP-0047: all four boards, and every mode named on the page
Some checks failed
ci / check (push) Failing after 3s
Details 
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.

- **F27 — the two competitive modes are scoring lenses over cooperative
play.** `scenario-panel` finds group success *exactly* equal across
SHARED GROUND, COMMON PROBLEM and BONDED COALITIONS in all 36 cells.
Correct arithmetic: `GreedyPolicy` maximises the group outcome and
never reads `state.mode`, so the same games are played and only the
winner set is carved differently. **Whether a mode changes how GROUND
is played is therefore untested**, and cannot be tested by any panel
built from the current policies — it needs one that plays for personal
score. `unplayed` rather than `inert`: the modes score correctly, they
have simply never faced a seat that wanted to win alone.
- **F28 — SHARED GROUND's mastery rating counts cards where the mode
card counts points.** *"All claimed Problem cards form one shared score.
… For a mastery rating, subtract 1 for each Blame token still in play
and 1 for each Denied Problem."* The shared score is claimed **value**
(`total`); `mastery` subtracts the same penalties from the claimed
**count**. Both readings fit the sentence and they differ on every game
where a 3-point Problem is claimed. Ours to report, theirs to rule.
**Sensitivity:** vary only the point value of the claimed Problems and
the gap moves with `sum(value) - count`. The two readings agree exactly
when every claimed Problem is worth 1 — no Problem in the edition is —
or when nothing is claimed, which is a loss. Everything else is held
fixed: same board, same penalties, same threshold.
- **F26 — a package that adds a FILE is invisible, where a package that
adds a column is not.** `h2-scoped-problem-stress` ships

> *"lets have a look at the cards and the rules to those cards again and
> implement all the scenarios and modes"*
## What was actually missing
The two halves turned out to be very different sizes.
**The modes were already implemented.** `ScoringMode`'s three arms all
score, `--mode` reaches them, F14 fixed the driver. What was missing was
that **nothing had ever compared them**, and the page never named them —
see below.
**The scenarios were not implemented at all.** `edition::deal` has taken a
`scenario_id` since the day it was written, and the only caller passed the
literal `"SCN_01"`:
```rust
let dealt = crate::edition::deal("SCN_01", seats)?;
```
**The seam was the whole mechanism and it sat unused.** 15 of the 20
Problem cards had never been dealt by anything — not a gate, not a panel,
not a player. Nothing was red, because nothing asked.
## Task: deal every board, name every mode
```task
id: CB-WP-0047-T01
status: done
priority: high
```
### The scenario is state
`GroundState.scenario`, `#[serde(default = "default_scenario")]` → `SCN_01`.
In the state for the same reason `variant` is (CB-WP-0038): the board and
the threshold follow from it, so a recording that did not carry it could
not be replayed.
**`standard-Np` keeps meaning `SCN_01`.** Twenty-six recorded scenarios
name that preset; a grammar that redefined it would have moved every one
of their boards while their hashes still claimed to pin them. `scn-03-4p`
names the rest. `--scenario` accepts `3`, `scn-03`, `SCN_03` or
`confidence` — ids are the edition's vocabulary, *"Broken Confidence"* is
the player's — and is validated against the edition, never a pattern, so
`SCN_09` is refused by name.
### The threshold now comes off the Scenario card
`threshold()` was `match seats { 0..=2 => 5, 3..=4 => 7, _ => 9 }` — the
engine's own copy of a number four cards already print, which is what F25
was raised about.
**The first version of this control was worthless and mutation said so.**
Reverting to the hardcoded bands left every test green, because all four
scenarios print 5/7/9 and the two paths are observationally identical on
every input the edition can supply. A control that cannot separate the
thing it is about from its fallback is not a control.
Fixed by splitting `threshold_from(list, scenario, seats)`, which can be
handed a card that **disagrees** (4/6/8). That test goes red under the
mutation; the loop over real scenarios never could.
### The page names the mode, the board, and what winning means
The header read `scoring CommonProblem` — the Rust variant's name, where
the Mode card is titled *"COMMON PROBLEM, PERSONAL EDGE"*. **CB-WP-0034
deleted this exact defect from the move buttons** and it was still
standing on the one line that says what winning means.
**And the coverage probe was holding it in place.** `("mode", "scoring
BondedCoalitions")` — a probe matching `Debug` output, which went red the
moment the defect was fixed. That is the **third** time this shape has
been found (CB-WP-0024, CB-WP-0034, here), and it is now specific enough
to state as a rule: *a probe that names a rendering pins that rendering;
probes name facts.*
The page now carries the Scenario's premise (*what happened*) and the Mode
card's rules text (*how this game is won*) — including the **tiebreak**,
which is a rule a player can play for: "lower Stress, then more Bonds"
changes what a losing seat should do in round five, and it lived in a
column nothing read.
### Mutations
| mutation | what went red |
|---|---|
| `setup` deals `"SCN_01"` regardless of preset | *"the four scenarios yield 1 distinct board"* |
| `threshold_from` ignores the card | *"the threshold did not come off the Scenario card"* |
| header back to `{mode:?}` | *"the page shows the Rust variant's name"* |
**Done 2026-08-08.** `make all` green. Verified live on
`make ground SCENARIO=4 MODE=coalitions`.
## What the panel found
`make panels` gained `scenario-panel`: 4 scenarios × 3 modes × 3 seat
bands, greedy throughout, 100 games per cell.
**1. Two of the four scenarios are the same board.** SCN_01 and SCN_02
have identical suits and values at every priority; every cell matches
exactly. Not a defect — a designed reskin is a legitimate choice — but
"four scenarios" buys **three** boards, and a panel that measured them as
four independent boards would be measuring one of them twice. Pinned by a
characterisation test so a future divergence is a decision, not a drift.
**2. SCN_04 is the hard board at 2 players** — 52% group success against
67% and 73%. It is the only deck that needs **two Repair** solutions in
the 2p deal, and the 2p Solution draw cannot always supply them. The seat
band the thresholds treat as uniform is not uniform across boards.
**3. The three modes produce identical play.** Group success is *exactly*
equal across all three modes in every cell. That is correct arithmetic and
a real finding: `GreedyPolicy` maximises the group outcome and never
consults `state.mode`, so **the two competitive modes are scoring lenses
over cooperative play**. `win/g` differs only by how the winner set is
carved from the same games. Whether COMMON PROBLEM and BONDED COALITIONS
change how the game is *played* is untested and cannot be tested by this
panel — it needs a policy that plays for personal score. Filed as F27.
**4. Every board is a formality at 6 players** — 100% group success in all
twelve cells. Consistent with F17's shape and with H2's motivation; noted,
not acted on.
## Not done here
- **No policy plays for personal score**, so F27 stands open and the two
competitive modes remain unexercised as *incentives*. This is the
largest remaining gap and it is the natural next pass.
- **SHARED GROUND's mastery rating counts CLAIMED CARDS, not points.**
The Mode card says *"All claimed Problem cards form one shared score …
subtract 1 for each Blame token still in play and 1 for each Denied
Problem"* — and the shared score is the claimed **value**, while
`mastery` subtracts from the claimed **count**. Underdetermined rather
than plainly wrong; raised for `ground-game` rather than changed here,
because scoring is theirs to rule on.
- **The trial log stamps the variant (CB-WP-0046) but not the scenario or
the mode.** A note from SCN_04 coalitions is indistinguishable from a
baseline SHARED GROUND note, which is the same defect one pass later in
two new axes. The marker already carries attributes, so this is small.
- **`design.py` reported an existing reproduction as absent.** It stats
`row["repro"]` directly, and the register writes **code spans** — so a
backticked file path was `os.path.exists("`games/…/x.rs`")` = False.
Named tests survived because `::` short-circuits before the stat, which
is why it had never shown. F27's panel existed and counted as debt
against a target of zero. ADR-0018's shape again: right computation,
wrong string. Fixed with three checks, including that stripping the
span must not turn the check off.
- **`catalog.yaml` and both `VARIANT.md`s were re-vendored in this pass**: `ground-game` moved H2
from `experimental` to `measured`, `decision: keep-as-experiment`,
citing our CB-EV-0032. That is their ruling on the previous pass, not
work done here.
