Data design and provenance
This build does not redistribute external observations because reuse permission was not verified. It uses a deterministic synthetic monthly snapshot, clearly marked in the downloadable provenance manifest. The research design mirrors the official series definitions for CPIAUCSL, INDPRO, and FEDFUNDS.
What expert work looks like
A credible desk separates the decision target from model inputs, honors release timing, retains a simple benchmark, and reports loss by forecast horizon. A richer model earns its place only when it improves held-out performance or supplies interpretable scenario information.
