## Ingest Pipeline Refactoring Kickoff

Nicholai initiated work on the `nicholai/ingest-pipeline` branch with a comprehensive refactoring plan for `packages/core/src/ingest/` (5631 LOC, 14 files). The core problem: each extractor wraps its own Ollama HTTP client instead of using the daemon's `LlmProvider` interface, hardcoding ingest to Ollama and blocking Claude Code support.

### Plan Overview

The refactoring has seven major components:
1. **Move `LlmProvider` interface** from `packages/daemon/src/pipeline/provider.ts` to `packages/core/src/types.ts` for dependency isolation
2. **Refactor extractors** (`extractor.ts`, `chat-extractor.ts`, `entire-extractor.ts`) to accept `LlmProvider` instead of Ollama config
3. **Rename `ollama-client.ts`** → `response-parser.ts` after deleting HTTP-specific code
4. **Unify extractor configs** by consolidating three identical config interfaces into a single `ExtractionOptions` type
5. **Extract `findGit()`** utility from code/entire parsers into new `git-utils.ts`
6. **Extract chat utilities** (time-gap batching, thread grouping constants) into new `chat-utils.ts` for slack/discord parsers
7. **Update `ingestPath()` entry point** to accept `provider: LlmProvider` parameter

### Key Architectural Decisions

- Factory implementations (`createOllamaProvider`, `createClaudeCodeProvider`) remain in daemon; only the interface moves to core
- Daemon's `llm.ts` singleton stays in daemon
- Domain-specific logic (prompts, parsing, message filtering) is intentionally NOT deduplicated
- Backwards compatibility via type aliases for old config interface names
- Circular dependency avoided by moving interface only, not implementations

### Scope Boundaries

Will NOT change: prompt builders, `parseExtractionResponse()`, format-specific message filtering, `threadToSection()` rendering, sequential processing loops, `index.ts` orchestration, chunker/provenance/parser logic.

Verification plan includes typecheck, build ordering (core → daemon), full test suite, and biome linting.
