 ## Roadmap
 
-- [x] **US1 — Track one provider (MVP):** OpenAI adapter, cost calculation, normalized event,
-      scoped `trace()`, console logging, graceful degradation. *(96% test coverage)*
-- [ ] **US2 — Provider parity:** Gemini, Anthropic, Ollama adapters; identical event shape.
-- [ ] **US3 — Output choice:** `JSONLogger`, `FileLogger`, `InMemoryStorageBackend`, full
-      `configure()` and multi-sink dispatch.
-- [ ] **US4 — Streaming & async:** `track_stream()` (one final event), async `trace()`.
-- [ ] **Hardening:** <5 ms / <20 MB benchmarks, thread/async isolation suite, docs, PyPI release.
-- [ ] **Beyond v0.1 (out of core scope, enabled by the extension points):** analytics,
-      prompt intelligence, AI FinOps, dashboards — all as downstream `LLMEvent` consumers.
+**v0.1.0 — Core SDK ✅ (current)**
+
+- [x] Track usage and cost across one provider (MVP): cost calculation, normalized event,
+      scoped `trace()`, console logging, graceful degradation.
+- [x] Provider parity: OpenAI, Gemini, Anthropic, Ollama adapters; identical event shape.
+- [x] Output choice: `JSONLogger`, `FileLogger`, `InMemoryStorageBackend`, full `configure()`
+      and multi-sink dispatch.
+- [x] Streaming & async: `track_stream()` (one final event), async `trace()`.
+- [x] Hardening: <5 ms / <20 MB budgets, thread/async isolation suite, docs, packaging.
+
+**Beyond v0.1** — each tier is additive on the five extension points; the v0.1 core API does
+not change. See [`ROADMAP.md`](ROADMAP.md).
+
+- [ ] **v0.2 — Analytics SDK** (`SQLiteStorageBackend` + usage queries)
+- [ ] **v0.3 — Prompt Intelligence** (per-prompt/template attribution)
+- [ ] **v0.4 — RAG Intelligence** (retrieval-aware accounting)
+- [ ] **v0.5 — AI FinOps** (budgets, alerts, remote pricing)
+- [ ] **v1.0 — Enterprise Platform** (stabilize the v0.x surface; dashboard, plugins)
