Sentiment

What it is

Sentiment — registry key sentiment.

HISTORICAL ONLY. third-party news-sentiment feed news-sentiment retired 2026-06 (DOCTRINE D22); FinRep-AI is the sole sentiment source. This column holds historical third-party news-sentiment feed values and goes NULL going forward (kept-forever per Retention policy, no producer registered). Was never scored or aligned — informational context only.

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.

How it’s computed

HISTORICAL ONLY. Pre-2026-06 values were the mean third-party news-sentiment feed NEWS_SENTIMENT Average_Sentiment_Score over the most-recent ~20 articles per cycle (3-band label: Bullish >0.15 / Bearish <-0.15 / Neutral). The third-party news-sentiment feed source (app/sources/sentiment.py) was retired 2026-06 per DOCTRINE D22; no new values are produced and the column goes NULL going forward. FinRep-AI per-article scores on news_items are the live sentiment substrate.

Where it surfaces

• API field: signals.sentiment_score on GET /api/v1/signals/latest
• Surface: daily_signals row (daily-cadence persistence)

Bands / thresholds

Classifier direction: higher_is_better.

Health-score / alignment role

Display-only — has bands for surface labeling but does not contribute to the health score (scoring is handled by a companion metric).

Release cadence

• Publishes: ad_hoc

Historical only — third-party news-sentiment feed NEWS_SENTIMENT retired 2026-06 (DOCTRINE D22); no future releases.
