Contributors verify a business email, confirm they may share the document, paste or upload it with structure intact, and tag its type; anything under NDA or of uncertain permission, and blank templates, are rejected. Eligibility is limited to the US, Canada, the UK, Europe, Australia and New Zealand, one or two documents per contributor. Enterprise writing is a register models handle poorly and the one least present in open corpora, because it lives inside companies; the use is enterprise document understanding, professional-register generation and workplace assistants that need to see what a real internal memo or status report looks like, not a model's idea of one. The task is permission-gated by design.
