Academic GCPI and operational CN series
GCPI (academic) is a standardised, weighted geometric-mean benchmark on a reference architecture,
documented in docs/methodology_outline.md.
CN-* series (operational research) are ComputeNav-panel statistics published as GCPI Research assets: primary units in USD (or %), with optional index points. They are not substitutes for the academic GCPI headline.
Panels are curated weekly in ComputeNav; index calculation and release artefacts are owned by this repository
(scripts/build_cn_indices.py).
