Run the Apier dry-run validator against a proposed regulatory action without producing ANY upstream side effect — no Maskinporten call, no Altinn / Skatteetaten / NAV submission. Use this BEFORE the live execute path to catch missing delegations, expired scopes, deadline misses, and payload-shape errors at zero upstream cost. The verdict carries five check slots (company_exists, system_user_authorised, scopes_delegated, deadline_in_future, data_format_valid — each pass / fail / skipped), the overall `valid` boolean, the DRY_RUN_DISCLAIMER (a pass is NOT a guarantee of upstream success), and the preview echo `would_be_payload` + `preview_notice`. Inputs match the /v1/actions/execute body: { org_number (9 digits, MOD-11), action_type (`mva_melding` | `a_melding`), period, payload }. Failure modes: SCOPE_INSUFFICIENT (needs read:actions), VALIDATION_FAILED; the validator never throws. To actually file a (sandbox) VAT return, use submit_vat_return instead. No sandbox mirror — under a sandbox bearer call submit_vat_return instead. Docs: https://www.apier.no/docs/guides/mva-filing
