H2's ATTACK dynamics, and a construction hazard found while measuring them
The H2 panel measured wins, variance and DARVO but not ATTACK selection —
which is F17's actual question. attack-value now runs H2 too.

The shape is the finding. Under H1 a seat that sometimes attacks loses
everything at 3p and above. Under H2 rank-75 wins 112/173/199 against
greedy's 120/175/199, while attacking and arming DARVO. So H2 makes
occasional ATTACK affordable — it does not make it pay. rank-75 never
beats greedy in any cell, and rank-95 (always attack) still wins 0
everywhere in all three variants, so "not always-attack-optimal" holds.

F17 therefore stands: ATTACK earns its place in no mode. What changed is
that choosing it is no longer catastrophic. Whether affordable is what the
design wants is ground-game's judgement.

And a hazard: with_variant() exists because H2 assigns Problem owners at
setup and `state.variant = v` leaves them unassigned, so scoped pressure
ticks nobody and H2 measures as INERT. Three call sites had the bare
write, including cb-play's driver.

No published figure is affected, and that was checked rather than assumed:
h2-panel used the builder, and the two harnesses with the bare write had
only ever run baseline and H1, neither of which has a setup step; the
driver has never played H2. All three fixed, and
a_bare_variant_write_leaves_h2_inert now states the difference so a
regression is caught by a named test rather than by a reader wondering why
H2 did nothing.

The builder was not enough — the field is public, so the old form still
compiles. Worth knowing before the next variant.

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.
