Run Conformance
Run the conformance suite against the bundled reference backend:
grafomem conformance -b aml.backends.gmp_reference:GMPReferenceBackend
Expected (reference store):
M8 = 1.000 · 7/7 PASS
What this means: every capability the backend declares passed its two-sided test, with each direction's bootstrap confidence interval excluding the failing outcome. See How conformance works and Interpreting results.
The same command audits any backend — yours, or a remote server over HTTP. See Remote server audit.
