DeltaSignal daily change evidence
deltasignal_daily_change_evidenceUse this read-only drilldown tool only when the user asks why one issuer or CIK was flagged in daily changes. It returns paginated raw CompanyFacts tag evidence for a specific ticker or CIK, plus page metadata and issuer identity. Parameters: ticker or cik is required; source_date is optional; limit defaults to 100 and is capped at 250; offset paginates the raw tag page. Behavior: read-only and idempotent; it performs one internal daily-changes read, filters evidence for one issuer/change, and has no destructive side effects. Do not use it for routine monitoring, Morning Brief, or Alpha Sweep unless the user explicitly asks for proof.
