Some checks failed
ci / check (push) Failing after 3s
T03 reported AM-5 at 87.0 s / 61.3 s and called it a 45% breach of the
60 s target. Re-measured with the fixed instrument on a quiet machine:
load before measuring: 0.14 per CPU over 8 CPUs — quiet
dev toolchain (default features) 37.3 s [ok target <= 60 s]
best of 3: 37.3, 42.9, 46.2 (spread 1.24x)
shipped runtime (--no-default-features) 41.2 s [ok target <= 60 s]
best of 3: 41.2, 50.8, 54.2 (spread 1.32x)
AM-5 is MET with 1.6x headroom. The 87.0 s was measured while the machine
was busy with mutation-check and cargo builds — a timing measurement under
contention measures the contention.
That is the same error class as AM-6's, committed two tasks later in the
same session by the same author, in the row immediately after the one
where it was diagnosed. Knowing the failure mode did not prevent it; only
building the guard did. That is the InnerLoop v1.2 design-goal argument
holding up under a third instance: optimize for cheap correction, because
prevention keeps not converging.
The instrument now refuses to measure above 0.5 load per CPU, takes the
best of 3, and warns when the spread exceeds 1.25x. Best, not worst: a
build-time ceiling asks whether the machine can do it in 60 s, the mirror
of AM-6's best-of-N for a throughput floor. The spread warning fired on
the shipped-runtime samples — consecutive clean builds degrade 37.3 ->
46.2 — so a quiet machine is not a uniform one either.
The escalation to a maintainer decision is withdrawn: there is no breach.
The build profiling done while the breach was believed real is recorded in
the log rather than acted on — 174 s of CPU work at only 3.2x parallelism
on 8 cores, a ~22 s serial proc-macro chain, lto=thin worth ~6 s, and
pinning ppv-lite86 to drop zerocopy making it worse (23 -> 25 crates).
With 1.6x headroom there is nothing to buy.

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.
