Local processing path

Selected media or live recording
  -> local FFmpeg normalization
  -> local whisper.cpp transcription
  -> local SQLite session and search data
  -> local Ollama summary/chat in Local Mode

Provider-aware boundary

With External API selected, original audio conversion and Whisper transcription remain local. Transcript text, prompt context, questions, retrieved excerpts, and provider-aware embedding input can be sent to the configured OpenAI-compatible endpoint. Returned generated content is stored locally according to the session workflow.

The global indexing path has a separate local background embedding phase; do not collapse it into the remote answer-provider path without inspecting the current implementation.
