AM-9 is met and gated: 13.4 MB peak RSS against a 64 MB target, 4.8x headroom, in `make all` via --fast. CB-EV-0001's "very unlikely to bind" was right, but it is now measured rather than assumed, and verified red by a property mutation (a 300 MB allocation in the workload). AM-5 is BREACHED on both readings, on the machine the spec names: dev toolchain (default features) 87.0 s [FAIL target <= 60 s] shipped runtime (--no-default-features) 61.3 s [FAIL target <= 60 s] bnt-lap001, 8 cores — a direct comparison, not a directional one. A row declared "recorded not gated" and never recorded fails its own target by 45% on first measurement. The tool reports and exits 0 because the spec says the row is ungated. Gating it is a spec change needing an ADR; a tool that promotes itself is how a target starts binding without anyone deciding it should. So AM-5 stays unmutatable — for the accurate reason now — and the breach is raised as a maintainer decision: speed the build, move the target by ADR (arguing why 60 s was wrong rather than why 87 s is convenient), or withdraw the row. The measurement itself had a real bug, found only by cross-validation. getrusage(RUSAGE_CHILDREN) is a high-water mark across every reaped child, so it attributed cargo's memory to the workload and reported 38.2 MB for a run that used 12.3 MB — a 3x over-report that was plausible, passed its target, and would have been published. Fixed with os.wait4, which returns that specific child's rusage, and the self-test now cross-checks against /usr/bin/time -v. That is the false-accusation shape in the measurement layer rather than the mutation layer: an instrument confidently reporting a number it had not earned. Also: the clean build measures into a throwaway CARGO_TARGET_DIR rather than running `cargo clean`, so measuring the metric does not cost several minutes of rebuild afterwards. A metric that punishes its own measurement gets measured once and never again. M-D1-MUT: 6 -> 7 of 14. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
