oho 9dfb9ff684 Update all documentation for Go daemon rewrite
All docs, README, and presentation now reflect the Go daemon architecture:
Python/FastAPI/LanceDB/PyMuPDF references replaced with Go/chi/SQLite/pdftotext.
Updated test counts (97), model names (qwen3-4b-2507), app bundle structure,
installer steps, and tech stack tables.

Operational Notes

Data Locations

Each workspace has its own data directory under ~/.knowledge-refinery/workspaces/<id>/.

Item Path
Workspace root ~/.knowledge-refinery/workspaces/<id>/
SQLite DB (metadata + vectors + graph) ~/.knowledge-refinery/workspaces/<id>/refinery.db
PID file ~/.knowledge-refinery/workspaces/<id>/daemon.pid
Workspace config ~/.knowledge-refinery/workspaces.json

Resetting

To start fresh, remove the data directory:

rm -rf ~/.knowledge-refinery

Monitoring

The Go daemon logs to stdout with structured messages. Key log patterns:

  • [pipeline] Stage: ... - Pipeline stage progress
  • [embedder] Embedded batch: X chunks - Embedding progress
  • [error] - Errors during processing

Live Pipeline Monitoring

During pipeline execution, real-time progress is available via the enriched /ingest/status endpoint. The daemon maintains:

  • Live progress dict: Per-stage status (pending/running/done) with progress percentages
  • Counters: chunk_count, annotation_count, concept_count, edge_count
  • Activity log: 200-entry ring buffer; the last 50 events are returned via the API

The SwiftUI app polls at 1.5-second intervals and renders a Pipeline Progress Panel with stage checkmarks, animated counters, and an auto-scrolling activity log. Polling auto-stops when the pipeline reaches idle/done state. The universe visualization auto-refreshes every 5 seconds during processing using mergeUniverse() for incremental node injection.

API Endpoints

Performance Considerations

  • Large files (>500MB) are skipped by default
  • Embedding batch size defaults to 32
  • SQLite uses WAL mode for concurrent reads
  • Pipeline runs in a background goroutine
  • Incremental processing skips unchanged files (content hash comparison)
  • Vector search: brute-force cosine similarity, all vectors loaded in memory (~150MB for 50K vectors)
  • Go daemon starts in <100ms, uses ~30MB base memory
