CB-WP-0025 T06/T07: a difficulty baseline that reports its own confound
T06. games/ground/examples/difficulty.rs, make difficulty, wired into make
self-tests, and a report file in ground-game under GROUND-WP-0005 with a
hub message pointing at it.

THE REPORT OPENS WITH THE RETRACTION, because what this task was written
to send was withdrawn by T02 and GROUND-WP-0005 is blocked on exactly that
number. They are told, in the first section, that we nearly sent them "the
game is too easy at 5-6 seats" and why it was wrong.

  seats  winnable  greedy  random  first-legal  spread
   2p      60%     60.0%    5.0%      76.7%      71.7
   3p      93%     88.3%    6.7%      25.0%      81.7
   4p     100%     93.3%    6.7%      30.0%      86.7
   5p     100%    100.0%    3.3%       0.0%     100.0
   6p     100%    100.0%    3.3%       0.0%     100.0

SPREAD justifies the whole redesign: 71.7 to 100.0 points between three
trivial policies. The table now shows why no single rate is a difficulty
rather than asserting it.

And the 5-6 rows point the OPPOSITE way from the withdrawn claim --
first-legal 0% against greedy 100% is the widest spread in the table,
which suggests play matters MORE there, not less. Neither reading is
established and the report says so.

The confound is stated in the tool's own output, not only in prose:
`winnable` is conditioned on greedy's play up to the final round, because
searching from round 1 is unaffordable. Presenting it as a property of the
deal would repeat this pass's error in a subtler form -- which is exactly
how a corrected project reintroduces a defect. NO THRESHOLD CHANGES ARE
PROPOSED.

The instrument can fail (spec §5): a witness must replay to a win, an
unwinnable position must report searched-out rather than a budget cut, a
one-node budget must not claim exhaustion, and the policy panel must
actually disagree. difficulty-baseline.rs marked superseded, kept as the
survey's dated snapshot. Registered as F16, inconsistent / withdrawn.

T07. evidence/CB-EV-0024. Five of nine defects came only from the review;
four from execution, and all four of those were in work written after it.
The wrong-denominator family now has five instances and still no control
-- facts-check catches copies that disagree, nothing catches a number
computed correctly against the wrong base. Tier L was an over-declaration
(no port, structurally M) and paid for itself anyway, because the review
is L-only. Chaos window 2 will close with zero overrides, making its
retirement condition untestable.

Named as open rather than implied done: the witness is NOT wired to the
ending page. The search works; the browser cannot ask it yet.

make all: exit 0. loop-lint clean.

clay-borg

A rebuild from scratch simulation and games engine framework set up to assimilate and optimize techniques and implementations useful for games, simulations, robotics.

Licensed under the Target Revenue Source License (TRSL V1C1) — see LICENSE; canonical text lives in the org's target-revenue repository.

Running the gates

make all                      # every gate, from a clean shell
make -C /path/to/clay-borg all   # …or from any other directory

There is no environment setup step. No cd, no export PATH, no activation script. make locates the repo from its own path and cargo from the standard rustup locations; the Python tools do the same via tools/repo.py. The only prerequisites are a rustup toolchain and Python 3.11+.

This is deliberate and enforced: make env-test runs every tool from / with a PATH containing no cargo, and make all includes it. CB-RES-0003 measured 84 agent turns and $15.33 spent prefixing commands with cd and export PATH before that friction was fixed at the root (CB-WP-0004 T01).

Other useful targets: make cost (spend per task), make cost-budget (spend since the last commit), make cost-mix (mechanical vs judgment turns), make loop-lint (executable InnerLoop rules), make self-tests (every tool's positive control).

GROUND

The first product vertical is a virtual tabletop implementation of GROUND — A Game of Bonds and Rivalry: DARVO Edition. The boardgame itself (rules, editions, content) is at home in the sister repository ground-game — that repo is authoritative for what GROUND is; clay-borg implements the engine that runs it.
