Protocol fixed before execution: 20 repeats per control,
shuffled with seed 20260905; a fresh verifier per attempt, no
cache, one command, and a 0.35-second timeout.
The five fixed controls are passing and failing Python
assertions about 2 + 2, an absent executable, a 2-second sleep
cut off at 0.35 seconds, and an absent Python import. These
trivial fixtures are not AI-generated patches or real project
test suites; their millisecond timings are not real project-test
latency.
Trusted fixtures use a temporary working directory, default
resource limits and no inherited environment. A temporary
directory is not a clean project copy or a security boundary.
Monotonic wall-clock time covers verifier construction, command
execution and classification. Measurement-program startup,
report serialization and network latency are excluded.
All attempts are retained, including slow and error attempts.
Median and nearest-rank p95 are descriptive statistics only: no
significance test, generalized accuracy estimate or causal
savings claim.
The JSON records revision, dirty-tree state, source hashes and
environment metadata. This is an internal pre-execution
protocol, not external preregistration or release approval.
