# Knowledge Vault

The Knowledge Vault (`internal/vault/`) manages markdown documents with `[[wikilinks]]`, bidirectional backlink indexing, and hybrid search (BM25 + pgvector).

```bash
# Search vault documents
dewee vault search --query "security policy"

# Upload document to vault
dewee vault upload --file ./runbook.md
```
