Bulk-import an external knowledge base into Prismer memory via the three-layer import pipeline (07 §3.1). Use when the user asks to import/migrate documents, a knowledge base, or notes into workspace memory. Layer 1 lands raw documents (zero LLM, instantly searchable); Layer 2 is YOUR distillation work — you read the landed documents and write candidate pages; Layer 3 commits candidates through the memory evolution gate. Distinct from the native memory_write tool face (that is for single, in-conversation writes).
