## 🎯 Key Decisions Finalized

### Technical Decisions

| Decision | Choice | Rationale |
|----------|--------|-----------|
| **AST Parser** | tree-sitter | Multi-language, fast, battle-tested (GitHub uses it) |
| **Storage Format** | JSON | Human-readable, Git-friendly, debuggable |
| **Fallback Strategy** | Built-in `ast` | Graceful degradation if tree-sitter unavailable |
| **Language Priority** | Python → JS/TS → Go/Rust | Covers 90% of users in 2 releases |
| **Indexing Mode** | Opt-out (default on) | Industry standard, with transparency |
| **NL Parsing** | Keyword-based (v0.11.0) | Simple, 70-80% accuracy, no dependencies |

---

### Strategic Decisions

| Decision | Choice | Impact |
|----------|--------|--------|
| **Feature Priority** | Repository Map first | Closes competitive gap with Aider/Devin |
| **Release Strategy** | Alpha → Beta → Stable | Gather feedback iteratively |
