tegwick 81e0aba59a CB-WP-0025 T05: the search works, and it falsified this pass's own
affordability projection

games/ground/src/search.rs, five tests. It finds real winning lines and
replays them through validate/fold to group_success.

Two bugs in my own work, found and fixed here.

THE TRAVERSAL WAS WRONG. It branched on "the first seat with any legal
command" and stopped there, so a later seat never acted if an earlier one
was already selected but still had a legal move. Restructured around what
the rules oblige: a seat without a selection MUST select (GR-R02) and
nothing else can happen first; after Reveal the optional actions branch
freely and the aggregate rejects Resolve until the obligatory ones are
done -- so the search needs no phase logic of its own.

AND MY REWIND WAS OFF BY ONE ROUND, replaying the round it was meant to
search. That is why the first run reported 3 nodes and looked like a
working search.

Measured with the real search, rewinding real games to the start of their
last K rounds:

  2p K=1  exhausted, 8,103 nodes, ~29 ms
  2p K=2  budget cut at 2,000,000 nodes, ~5 s
  3p K=2  win found, 41 nodes, ~157 us

The spec's own falsifier said "§3 fails if K=2 proves unaffordable at four
seats". IT FAILED AT TWO. The projection assumed a joint product per
round; the search explores sequential per-seat decisions, so orderings
multiply the tree far beyond width^seats. That is the second projection
this pass published in place of a measurement -- C1's timer was the first.

THE ASYMMETRY IS THE OPERATIVE FINDING. Finding a win is cheap: DFS
stumbles onto one in tens of nodes. Proving none exists needs exhaustion.
So the witness feature is affordable now at any K a player would ask
about, and the winnable fraction (ADR-0013 D4) is NOT, because its
negative half must exhaust every deal it counts. K=1 is the honest default
for exhaustive answers today; making K=2 exhaustible needs transposition
or move-ordering, neither of which this pass built. specs §3 and §3.1
corrected accordingly, and the K=2 default withdrawn.

The negative control that makes "winnable" falsifiable: 2p seed 7 over its
last round returns NoneFound with exhausted=true in ~8k nodes -- a real
negative, not a budget cut wearing a verdict's clothes. And the visible/
hidden marking is tested both ways, since a marking that can only say YES
is decoration.

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.

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.
