Replace double-nested stem loop (stems × tokens) with single-pass
stem frequency map. For 100 unique tokens per file: 10,000 iterations
→ 100 iterations per file. Critical for large vaults.
Performance optimizations for large vaults:
- Barnes-Hut quadtree repulsion (O(n log n) for >200 nodes)
- Naive O(n²) preserved for small graphs (<200 nodes)
- Graph cache: reuse data when same (vault, path, depth, scope, tag)
- Cache key displayed in info bar: '(cache)' label
Backend (main.py):
- GraphNode: added tags, incoming_count, outgoing_count
- GraphEdge: added 'backlink' relation
- GraphResponse: added 'scope' field
- api_graph: scope=full|directory, tag= filter, backlinks
- Full-vault tree walk with configurable depth 0-3
- Tag index from in-memory file index for fast filtering
- Incoming/outgoing link count per node
Frontend (graph.js + index.html):
- Theme-adaptive colors via CSS custom properties
- Depth slider (0-3) with live reload
- Full-vault toggle button (🌐 Tout / 📁 Dossier)
- Search input with tag filtering + visual highlighting
- Tooltip on hover (name, path, tags, link counts)
- Backlink edges rendered in red dashed
- Node size proportional to link count
- Larger modal (1000px, 85vh)
Add French snowball stemmer to tokenization pipeline:
- Index both original tokens AND their stems in InvertedIndex
- Query terms are also stemmed before lookup
- Stemmed forms accumulate TF from all original forms
- Lazy-init singleton pattern for stemmer
The login() function used 'request: LoginRequest' which shadowed
FastAPI's Starlette Request object. Request.client was accessed on
the LoginRequest Pydantic model instead of the HTTP request, causing
AttributeError: 'LoginRequest' object has no attribute 'client'.
Fix: rename the Pydantic parameter to 'body' and add explicit
'request: Request' for IP extraction and rate limiting.
