Charter schema — declarative mission spec a charter author writes.
ActivityBus / InMemoryActivityBus — pub/sub for tool.start, tool.end, chat.user, chat.assistant, artifact.*, milestone events. Subscribers throwing don't poison the bus.
Article 12 audit chain — append-only Merkle log with bundle export (manifest + chain.txt + events.csv + bundle.sha256). Built for the Aug 2 2026 EU AI Act enforcement deadline.
Logger + sinks — structured logger that fans out to stdio + JSONL
- OpenTelemetry sinks.
