MC Market Cards
Guardrails

Verifier first, human publish second.

The verifier prevents risky language, unsupported claims, and weak card structure. Human review is still mandatory before public publishing.

Verifier checks

Required fields

Headline, takeaway, sections, confidence, and card type must exist.

Banned language

Recommendation terms such as buy, sell, hold, target price, stop loss, and guaranteed upside are rejected.

Causality

Direct claims such as “rose because” or “caused by” are rejected when evidence is circumstantial.

Numbers

Numeric claims must be present in the evidence packet move snapshot or supporting evidence.

Evidence references

Section evidence IDs must reference known evidence items or events.

Uncertainty

Cards must include unclear, missing, undisclosed, or not-found context.
