# Report cash discrepancies for a period

> Returns the per-session expected-vs-counted cash variance report over the LIVE register-session projection, plus an aggregated summary. Optionally narrow by `from` / `to` (`YYYY-MM-DD`, inclusive; `from <= to`) and `store`; absent bounds mean all time. A malformed or inverted period returns 400.

    The Solya POS backend HTTP surface. Every documented operation is
    agent-ready: it carries an `operationId`, an agent-facing `description`, the

    Success responses return the payload as raw JSON; failures return the
    `ErrorResponse` envelope (`{ error: { code, message, statusCode } }`).
