Japan 40Y JGB yield
What it is
Japan 40Y JGB yield β registry key jp40y_yield.
Japan 40-year JGB yield (Japan MoF interest-rate CSV, super-long). Published on Tokyo time, so it lags the ET grid by about a day. long-end supply-stress carrier, Phase 2 of improvements/long-end-stress.md; scoring deferred to a pre-registered study.
Data-pyramid tier
T1 β Signal. This metric sits at the signal layer of the platformβs six-tier data pyramid (T0 raw inputs β T5 actionable read). The tier reflects how far the value is from a raw measurement β not how strongly it is validated. Abstraction and validation are separate axes: a higher tier is not a claim of stronger evidence.
Horizon & validation
No validated skill horizon is on file for this metric β read it as context / a data carrier, not a validated edge. Stamps are added only when a gated research verdict lands.

Health-score / alignment role
Data carrier β no implication, no health-score contribution.
Persisted for downstream consumers (sparklines, base-rate matcher, calibration substrate) but does not classify into BULLISH / NEUTRAL / BEARISH and does not contribute to the 0-100 health score.
