An enskild firma that hires staff should get the payroll module, but its owner or board can never be on payroll (owner compensation is egna uttag / BAS 2013, not lön). - Migration 20260628120000 adds the enforce_ef_no_owner_employee trigger (BEFORE INSERT OR UPDATE OF employment_type) as the all-paths backstop. - lib/salary/employment-rules.ts is the app-layer mirror (forbidden set kept byte-identical to the trigger); getCompanyEntityType() resolves the same company_settings -> companies precedence. - The two UI salary routes and the v1 POST guard before insert/update for a clean 400 with guidance. - Payroll nav + Lön settings now show for any employer (aktiebolag OR company_settings.pays_salaries), wired through the dashboard layout. Fixes #782. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
