Production attestation GETs canonical URLs twice (public/cached view and origin), including Capability HTML, via npm run attest:production --write
(published at /.well-known/calculatorx-production-attestation.json) and fails if the public Capability page advertises a different calculation_version. This is artifact consistency, not an independent immutable release log.

|---|---|---|---|
golden-rect-na | golden | pass | Expected tau=1.5 · V=12 · Q=9 · I=36 · b=2 · model=transverse_shear · Actual model=transverse_shear · V=12 · Q=9 · I=36 · b=2 · tau=1.5 · solver=jourawski · convention=τ = VQ/(I b) at one line across the section. The sign of V is the sign of τ. Q, I, and b are inputs. A rectangle built from width and height is its own page. |
