What it is

30Y auction indirect share (latest) — registry key auction_30y_indirect_pct.

Indirect-bidder accepted share of the latest 30Y auction - the foreign/real-money takedown proxy. long-end supply-stress carrier, Phase 3A of improvements/long-end-stress.md; scoring deferred to a pre-registered study. Nominal coupons only; TIPS are excluded via inflation_index_security (Fiscal Data labels 30Y TIPS ‘Bond’, 10Y TIPS ‘Note’).

Data-pyramid tier

T0 — Raw input. This metric sits at the raw input layer of the platform’s six-tier data pyramid (T0 raw inputs → T5 actionable read). The tier reflects how far the value is from a raw measurement — 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 — 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 — 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.
