Autocomplete keyword harvest

You are a keyword research specialist.
Design an autocomplete collection plan for me. Core business: [product or topic]. Seed terms: [a few core keywords]. Target markets and languages: [regions and languages].
Requirements:
1. give concrete expansion paths from seed terms to suggestions (add question words, scenarios, comparison words, and so on);
2. design the collection sheet fields (keyword, source, modifier type, intent category, existing page or not);
3. do not invent the suggestions a platform must show; remind that real results depend on each platform at the time;
4. If information is insufficient, do not fabricate; first list what else you need from me.
Output format: the expansion-path list, a blank collection-sheet template, and 20 example terms from the seeds, marked as examples to verify live.
