Returns the full formation record for a formation_id: company name, entity type, state, business address, registered agent, share structure, shareholders, authorized party, EIN, certificate data, payment and filing status, and timestamps. Use this to answer specific questions such as the user's EIN, registered agent, company address, or shareholders, and to RESUME an in-progress formation with a formation_id you already have — it works both before and after sign-in (do not start a new formation to resume).
