Concepts

Definitional anchors referenced by multiple other nodes.

Status: Phase 2-3 placeholder

Concept pages are created on demand as soon as a term is referenced by ≥3 other nodes. If a concept is only used in one place, it's defined inline there.

Likely entries:

  • Completeness ratio — how complete the current month is (used in extrapolation, see processing.py blending logic).
  • Trend-type quadrant (ADI/CV²) — the four classes (smooth / intermittent / erratic / lumpy) that gate forecast model selection.
  • Tier (history-length tiers) — Tier 1 (< 6 months), Tier 2 (6-23 months), Tier 3 (24+ months); how growth is computed differently per tier.
  • Shard / range — how keywords_data_local is partitioned (200 shards by farmFingerprint64(keyword) % 200, each subdivided into 256 ranges).
