+- Nothing in flight — S0 is closed; S1 is next.
 
 ## What's next
 
-1. **Architecture decision records** — ADR-0001..0004 capturing the foundational
-   decisions (independent implementation, macOS-first, native-rendered, Zig).
-2. **Close S0** — verify exit criteria, close the milestone.
-3. **S1 — Engine core** — the pure-Zig OCPP types, parser, normalizer, and
-   session correlation.
+**S1 — Engine core (0.1.0):** the pure-Zig OCPP engine — canonical `Event` /
+`Session` / `Failure` types, the parser (JSON object, JSONL, bare array), the
+normalizer (direction inference + timestamp normalization), and session
+correlation by transaction id. Headless and testable via `native test`.
