What's New

Core Features

• Project-Aware Namespacing — Auto-detects git repo and creates per-project Qdrant collections. --project and --global flags on all commands (#109)
• Tiered Search — Narrow-to-wide retrieval across 4 tiers: working context, recent, structured, archive. Early return on confident matches (#120)

• Odin Background Sync — Bidirectional sync with deletion propagation
• Depersonalization — Removed hardcoded references for public usability

Quality

• 1,118 tests passing (99.4% coverage)
• PHPStan level 8 with strict rules
• Laravel Pint formatted
