Some checks failed
ci / check (push) Failing after 4s
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 Withdrawn entirely: "H1-B suppresses DARVO in the attacker".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.

# Purpose
|
||
|
||
```
|
||
structural tier M (adds a policy to the panel every future difficulty
|
||
and design measurement is reported against)
|
||
chaos d8 = 2 → no override
|
||
declared tier M
|
||
```
|
||
|
||
**Declaration 11 of chaos window 3.**
|
||
|
||
## Why
|
||
|
||
[CB-EV-0030](../evidence/CB-EV-0030-h1-measured.md) §4 named this as the
|
||
measurement it had not run, and it is the one that decides whether H1's
|
||
verdict is about **H1** or about **greedy**.
|
||
|
||
H1 assumes rising Stress pushes a table toward the DARVO arm. It does not,
|
||
**because greedy regulates**: `Action::Ground if gated => 100` makes
|
||
GROUND the top choice the moment the stress gate bites, so Stress
|
||
plateaus at 3 and neither the gate (4) nor the arm (5) is ever reached.
|
||
|
||
> **Every policy in that panel was greedy-family.** So "H1 does nothing"
|
||
> may be "H1 does nothing *to a seat that already manages its Stress*" —
|
||
> and H1 was written for the seat that does not.
|
||
|
||
## The one preference that varies
|
||
|
||
`Reactive` is `GreedyPolicy` with **GROUND demoted below ATTACK**, and
|
||
nothing else changed. It is the player who chases Problems and ignores
|
||
their own state — which is not a straw man: it is the commonest way a
|
||
person plays a co-operative game badly, and the behaviour GROUND's whole
|
||
Stress economy exists to punish.
|
||
|
||
**One preference, per ADR-0018 and the same discipline as
|
||
`attack-value.rs`'s `Attacker`.** A policy that differed in several places
|
||
would tell us a variant is different without saying which difference did
|
||
the work.
|
||
|
||
## Task: the policy, and the measurement
|
||
|
||
```task
|
||
id: CB-WP-0039-T01
|
||
status: done
|
||
priority: high
|
||
state_hub_task_id: "2c509cdb-aedb-4dce-a21f-f16bcdf17d80"
|
||
```
|
||
|
||
**Controls:**
|
||
- **exactly one preference differs from greedy**, and the artifact says
|
||
which;
|
||
- **both variants, same instrument, same run** — otherwise the comparison
|
||
is between harnesses;
|
||
- **the game count is reported**, because CB-EV-0030 §3's harness defect
|
||
was silently discarding games and printing zeros that read as losses;
|
||
- **the answer may be that H1 still fails**, and that is reported as
|
||
plainly as the other outcome.
|
||
|
||
**Done 2026-08-08, then CORRECTED after adversarial review**
|
||

|
||

|
||
|
||

|
||
|
||
**It changed CB-EV-0030's verdict**, and that part survives: H1 does reach
|
||
the unregulated seat. DARVO arms **2 per seat per game**, scaling with the
|
||
table — the earlier flat "400 in every cell" was the broken policy.
|
||
|
||
**Criterion 3's verdict is corrected and was wrong**: reactive wins
|
||
**66 at 2p against greedy's 68**, not "nothing at any seat count". It wins
|
||
nothing at 3p and above, and so does greedy.
|
||
|
||
**The baseline observation survives only in a narrower form.** Peak Stress
|
||
*held* across the **1,600** baseline games was **2** — the starting value,
|
||
never exceeded. The original said **1** because the metric maximised over
|
||
`StressSet` event payloads and the starting value is written by `setup`,
|
||
never by an event: **wrong subject**, in the pass that was written to
|
||
correct a wrong-subject error.
|
||
|
||
And the generalisation was refuted by this repo's own harness: the rank-95
|
||
policy *is* a reckless policy and it drives Stress to 5 under **baseline**.
|
||
What survives: under the two policies here, neither of which selects ATTACK
|
||
under baseline, **no Stress is ever added** — ATTACK is the sole inbound
|
||
pressure.
|
||
|
||
**The H1-B suppression claim is WITHDRAWN.** It was inferred from a
|
||
constant that the broken policy produced, and disabling H1-B under the
|
||
corrected policy changes the arm count by **exactly zero** in every cell.
|
||
The inference was also invalid on its own terms: final Stress does not
|
||
record who armed, because `DarvoEnded` resets the stage and REVERSE gives
|
||
its owner −2.
|
||
|
||
**The pass hedged the wrong variable** — it disclaimed "the number 2" and
|
||
defended "the direction", and the direction is what failed.
