No official figure published for: recommended RAM, minimum CPU cores

Docs give one required RAM minimum (4GB) and one recommended-minimum CPU figure (4 cores) for the base workload tier. The 8-core/8GB figures are a higher-conversation-volume scaling tier, not a general recommended baseline above the stated minimums (Defect Class #2) — not harvested as rec/min counterparts.

We publish nothing we can't source. Evidence of the gap.
