Update workflow

Daily checks. Weekly summaries. Quarterly resets.

Lineum is built for investors who want the important changes without rereading every form, fund page, and company update from scratch.

Quarterly reset

Quarterly releases get the deeper review cycle.

The reset is where stale notes, changed risks, fund holdings, and new filing data are reconciled into a cleaner research view.
