The gates existed; CI ran half of them and tolerated the failure case.
- cb-sim no longer has a "tolerable" non-zero exit. An unregistered game
prefix is a failure, and a run in which nothing executed is a failure.
Previously CI carried `|| test $? -eq 2`, so renaming a scenario prefix
would have skipped every scenario while the pipeline stayed green.
Verified with a negative control.
- CI now runs make coverage (AM-1) and make dep-weight (AM-4), both
added after CI was written and neither enforced until now.
- dep-weight enforces its targets instead of only reporting them.
- CI lints the shipped-runtime configuration separately, so the feature
split cannot rot unnoticed.
- Dropped the stale `make deps` target, which still measured the retired
crate-count metric.
The positive-control rule is now executable: CI runs
`cargo bench -- --test`, which executes every benchmark once, so a
workload that stalls fails the build.
That step immediately found a fourth instance of the error class it was
written for. The committed replay benchmark was the broken version — an
earlier patch never applied, leaving a command sequence that omits
Resolve, so every round produced nothing and the log-building loop spun
forever. It had never run to completion; the reported AM-7 replay
numbers came from a probe test instead. Fixed, given the same positive
control as the round loop, and re-measured from the benchmark: 100k
events fold in 2.18ms (95% CI 2.14-2.23), against a 5s budget.
Evidence now reports confidence intervals rather than point estimates,
so the 3% regression rule in MetricsAndScenarios is enforceable.
The finding worth carrying: writing the positive-control rule into
InnerLoop v1.0 did not prevent the next instance. Making it a CI step
did.

evidence/CB-EV-0001-game-kernel.md records the acceptance run against
the CB-RES-0001 baseline.
Met: AM-1 rule coverage 58/58; AM-6 throughput 1.65M events/s against a
100k target; AM-7 scaling 1.08x at 20x workload and a 100k-event replay
in 4.13ms against a 5s budget; AM-8 zero divergence over 10 full runs
with fmt and clippy clean; AM-10 zero foreign collection types.
Not met and reported as such: AM-4 at 33 transitive crates against a
<=20 target. Attribution is in the evidence file. The recommended fix
is making serde_yaml optional (-5, a test-only concern), after which
the remainder is sha2 and rand_chacha, which K5 and K7 require. We are
not hand-rolling crypto primitives to win a dependency count.
AM-12 is recorded as uncomputable: per-task token counts were never
instrumented, and inventing a USD figure would defeat the metric.
A measurement error was found and corrected before publication. The
first benchmark reported 9.3M events/s on a flat curve. The workload
had a player selecting SUPPORT while parked at Stress 4, so GR-R03
rejected it, rounds never completed, and throughput was computed for
rounds that never happened. The bench now asserts the per-round event
count and panics rather than measuring a stalled loop. The corrected
figure is 5.6x lower.
The evidence file states plainly what the boardgame.io comparison does
and does not support: the ~450x command-rate ratio is cross-runtime and
cross-feature-set, so it is a direction, not a verdict, per the
InnerLoop parity-cap rule.
