capital_change_brief

Active

declared in 1.1.0

Compose the current evidence-backed capital-change brief for one ticker. Use when a user asks what changed in reported institutional ownership, which tracked managers drove it, whether qualifying Form 4 open-market activity points in the same or opposite direction, and wants the SEC proof. Current-only: pass ticker only; as_of and since are not supported. Returns an explicit outcome and coverage, manager changes, insider activity, corroboration, filing evidence, and a derivation manifest. When direction is withheld, read quality_artifacts for bounded, machine-readable reasons and hidden-row examples. Every evidence ID on an artifact example has a rich object in evidence; manifest.evidence_ids is the complete aggregate set, and the corroboration claim points to it through evidence_reference. Lead with the headline, counts, largest drivers, Form 4 stance, and coverage. Cite relevant human_url evidence links. 13F changes are reported quarter-end positions, not trade dates, real-time flows, intent, or investment advice.
