Each phase now includes: - Exact code locations (which crates/files) - Function signatures and method stubs - Unit tests with expected behavior - Integration tests for end-to-end verification - Homelab vault structure (test data) - Performance benchmarks and targets - Verification checklists Phases 1-7 now actionable: 1. Wiki-link graph indexing (parser + repo + SQL schema) 2. Multi-scope TF-IDF (global + project-local + chunk metadata) 3. Hybrid retrieval (wiki-scoped router + RRF fusion) 4. LLM call optimization (chunk selector with budget) 5. Chunk metadata extraction (heading + key terms + category) 6. Cache alignment (locality-aware wiki traversal) 7. OIDC + RBAC (JWT parsing + policy engine + audit logging) End-to-end test scenario provided.
