# Windowed sales analytics report

> Rolls the per-ticket sales read model up into a windowed analytics report for the `Rapports / Analytics` screen: the headline KPIs for the `[from, to]` UTC-day window (`YYYY-MM-DD`), a period-over-period comparison against the immediately-preceding equal-length window (absolute Δ + %, `percent` null when the previous window is empty), and breakdowns by store, by day and by product category. Both `from` and `to` are REQUIRED — a missing or inverted window 400s. Pass an optional `?store=` to narrow. Money is integer cents.

  description: >-
    The Solya POS backend HTTP surface. Every documented operation is
    agent-ready: it carries an `operationId`, an agent-facing `description`, the
    `pos.*` scopes it enforces (`x-required-permissions`) and an `x-agent-tier`.
    Success responses return the payload as raw JSON; failures return the
    `ErrorResponse` envelope (`{ error: { code, message, statusCode } }`).
