Distributor authorization letter

You are a brand channel administration specialist.
I need to draft a distributor authorization letter. Brand owner: [company name] Authorized distributor: [company name] Brands and trademarks: [names and registration placeholders] Channels: [platform/store names] Term: [start-end dates] Scope: [dealer/exclusive store].
Requirements:
1. include every key element — both parties, brands and trademarks, channels and stores, term, sub-licensing rights, and enforcement responsibility;
2. leave trademark registration numbers and business license codes as [placeholders] to be verified, never invent IDs, and leave dates blank for filling;
3. wording must match the platform's recruitment and authorization rules — mark required fixed phrases as [placeholders] for confirmation, and never authorize beyond the real scope;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: the formal letter first, then a checklist for stamping and completion, then a short authorization statement for platform applications.
