Create Company

Wizard company identity — industry is required here (ZET-157).

The admin POST /companies/ body (:class:CompanyCreate) keeps industry nullable, and CompanyUpdate's explicit-null-clears semantics are untouched — the requirement is wizard-only. Rationale: a null industry seeded the 72-account base chart with no industry overlay (e.g. no 3400 Dienstleistungserlöse for a services tenant) and left ar_revenue_default_account_code at the base 3000, and the gap only surfaced at the first revenue booking. Any non-blank string is accepted — unknown/freeform keys (including the wizard's "Other / not listed" fallback) still resolve to the base chart, but that is now an explicit choice, never a silent default.

Optional integration accounts/drives to create with the company.

The accounting settings the wizard collects (defaults applied in the service).

F2478 (1) — the bank step's confirmation (owner decision 2026-09-27): the bank accounts declared in this onboarding are ALL of the company's business accounts, and takings says whether cash / payment-provider takings exist and are imported too (imported) or do not exist (none). Stored once, dated, with the onboarding user (vat.bank_completeness); the SSS entry test proves a quiet stretch nil from these accounts' statements only. Omitted = not confirmed (the Settings page can do it later).

A balance-sheet snapshot (analyze output and create input).

On analyze output resolution_json / equity_roles / source_document_ref are unset; the wizard fills them after the resolve-balance step and resends them.

A P&L summary (analyze output and create input).

The final (reviewed/edited) opening-entry proposal to persist + post to the GL.

The invoice-sender identity — the address is required (ZCT-513).

Seeds the company's default issuer profile (invoiage_core.ar.defaults) in the atomic create, and the remaining fields (VAT number, creditor bank account, the creator's email) are enriched on top of it, fill-only.

⚖️ Owner ruling 2026-09-03. address_line1/postal_code/city used to be optional, the seeded profile was written with an empty address on purpose, and the gap surfaced only when someone tried to issue — which is how FenX AG reached a finished draft it could not send (ZCT-513). They are now required and non-blank. The three are exactly what issuing needs end to end: ar.validation blocks on a missing name/address, and qrbill refuses a combined address whose second line ("<postal_code> <city>") is empty, silently dropping the Swiss payment part (ZCT-541). address_line2, country and the contacts stay optional.

🔴 A deliberate, owner-reaffirmed breaking change, recorded here so it is not "fixed" back: a programmatic create that omits the address now 422s. That includes onboarding_create_company over MCP — the path FenX AG and Felina Food AG were created through, and the one the ZCT test cycle uses.

Blankness is checked as well as presence, for the reason OnboardingCompanyIn. industry gives below: min_length alone accepts " ", and a whitespace address is the same broken invoice as no address, arrived at through the same empty form field.

Company payroll setup: every sub-section optional (partial setup is fine — run validation names what is missing). The statutory rate schedule and the wage-type catalog are auto-seeded at company create; this adds only the company-specific insurer planes on top.

Per-section counts of what the atomic create persisted.
