# Open a plan

> Opens a plan in `DRAFT`, always — nothing is ever created already decided. The body is narrowed by `family`: the four supplier families REQUIRE `supplierId` (an order with no supplier cannot be issued, costed, or checked against a negotiated term), a rebalance requires two DIFFERENT shops, a markdown requires the operation's name and its dates — with `endsAt` on or after `startsAt`, a cross-field rule JSON Schema cannot express, so a period running backwards 400s on `endsAt` rather than being visible in this spec. `reference` is what will be quoted in an email to a supplier and is unique across the network. The family and the counterparty are frozen from here on: if either is wrong, cancel the plan and open another.

    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 } }`).

        Opens a plan in `DRAFT`, always — nothing is ever created already
        decided. The body is narrowed by `family`: the four supplier families
        REQUIRE `supplierId` (an order with no supplier cannot be issued,
        costed, or checked against a negotiated term), a rebalance requires two
        DIFFERENT shops, a markdown requires the operation's name and its dates
        — with `endsAt` on or after `startsAt`, a cross-field rule JSON Schema
        cannot express, so a period running backwards 400s on `endsAt` rather
        than being visible in this spec. `reference` is what will be quoted in
        an email to a supplier and is unique across the network. The family and
        the counterparty are frozen from here on: if either is wrong, cancel the
        plan and open another.
