Phase 5 of the Companion Brain. Introduces the Companion Chat that
ties together all previous phases into a conversational interface.
Module (modules/companion/):
- types.ts: LocalConversation + LocalMessage with tool call/result fields
- collections.ts: companionConversations + companionMessages tables
- stores/chat.svelte.ts: conversation + message CRUD
- queries.ts: reactive useConversations() + useMessages()
- engine.ts: chat orchestration — builds system prompt from Context
Document, sends to local LLM (Gemma via @mana/local-llm), handles
tool calls via JSON extraction + executeTool(), supports multi-round
tool calling (max 3 rounds)
UI:
- CompanionChat.svelte: message list, streaming output, tool result
display, keyboard submit (Enter)
- /companion route: sidebar with conversation list + chat area
Also updates the architecture plan with Phase 1-4 completion status.
