What is not publicly established
The reviewed public customer resources do not provide a complete executive-case employee roster, internal repurchase criteria, or a guaranteed escalation timeline. This guide does not claim to know employee motives, every internal scenario, or the outcome of any individual claim.
How recommendations are distinguished
The contact details and legal/program summaries link to their sources. The action sequences, scripts, checklists and templates are editorial consumer guidance synthesized for clarity. They are not leaked procedures, official GM instructions, legal advice or a promise of eligibility.
