Design a production-grade intent taxonomy for [ProductLine] focused on the top tasks [TopTasks] across [Languages]. For each intent, define 5–10 diverse sample utterances, required/optional slots, synonyms, slot validation rules, confirmation strategy (explicit/implicit), and fallback policy at a [ConfidenceThreshold] threshold. Recommend an NLU stack on [NLPPlatform] with custom entity extraction where needed.
Output format: Provide a table: [Intent ID | Intent Name | Sample Utterances | Slots (name:type:required) | Entities/Synonyms | Validation Rules | Disambiguation Prompt | Acceptance Criteria]. Include a JSON snippet showing the canonical intent/slot schema and confidence handling policy.
