6740a017c7 PRD v2: production roadmap with ingest, vector search, hot cache phases 
- Phase 6: Ingest pipeline (CSV/JSON → schema detect → Parquet → catalog)
- Phase 7: Vector index + RAG (embed → HNSW → semantic search → LLM answer)
- Phase 8: Hot cache + incremental updates (MemTable, delta files, merge-on-read)
- ADR-008 through ADR-011: embeddings as Parquet, delta files not Delta Lake,
  schema defaults to string, not a CRM replacement
- Staffing company reference dataset (286K rows, 7 tables)
- Honest risk assessment: vector search at scale and incremental updates are hard

b37e171e10 UI redesign: Ask, Explore, SQL, System tabs 
- Ask: natural language → AI generates SQL → DataFusion executes → results
  Shows the AI-over-data-lake story: schema introspection → LLM → query
- Explore: click dataset → schema + preview + AI-generated summary
- SQL: raw DataFusion SQL editor with Ctrl+Enter
- System: health grid testing all 5 services + embeddings + generation
- Example prompts for quick demo
- Dark theme with accent styling

b235ef9201 Fix nginx route collision — namespace lakehouse API under /lakehouse/api/ 
Previous regex routes for /catalog, /storage, /health intercepted main site.
Now all lakehouse API calls go through /lakehouse/api/ prefix, stripped by nginx rewrite.

387ce0074c UI: full-stack test coverage with tabs for Query, Storage, AI, Status 
- Query tab: SQL editor with results table (existing)
- Storage tab: list objects, register datasets pointing at storage keys
- AI tab: embed (nomic-embed-text), generate (qwen2.5), rerank with scored results
- Status tab: health checks for all 5 services + functional tests (embed, generate, SQL)
- nginx: added /lakehouse/ and API proxy paths to devop.live config
- Loaded 3 sample datasets: employees, events, products
- Fixed Rust 2024 reserved keyword `gen`

50a8c8013f Phase 4: Dioxus frontend with dataset browser and SQL query editor 
- ui: Dioxus WASM app with dataset sidebar, SQL editor (Ctrl+Enter), results table
- ui: dynamic API base URL (same-origin for nginx, port-based for local dev)
- gateway: CORS enabled for cross-origin requests
- nginx: lakehouse.devop.live proxies UI (:3300) + API (:3100) on same origin
- justfile: ui-build, ui-serve, sidecar, up commands added

239e471223 Phase 3: AI integration with Ollama via Python sidecar 
- sidecar: FastAPI app with /embed, /generate, /rerank hitting Ollama
- sidecar: Dockerfile, env var config (EMBED_MODEL, GEN_MODEL, RERANK_MODEL)
- aibridge: reqwest HTTP client with typed request/response structs
- aibridge: Axum proxy endpoints (POST /ai/embed, /ai/generate, /ai/rerank)
- gateway: wires AiClient with SIDECAR_URL env var
- e2e verified: nomic-embed-text returns 768d vectors, qwen2.5 generates text

19bdfab227 Phase 2: DataFusion query engine over Parquet 
- queryd: SessionContext with custom URL scheme to avoid path doubling with LocalFileSystem
- queryd: ListingTable registration from catalog ObjectRefs with schema inference
- queryd: POST /query/sql returns JSON {columns, rows, row_count}
- queryd→catalogd wiring: reads all datasets, registers as named tables
- gateway: wires QueryEngine with shared store + registry
- e2e verified: SELECT *, WHERE/ORDER BY, COUNT/AVG all correct
