**Scenario contracts and run reports** add shared Python/TypeScript environment hooks plus progress, utilization, campaign, goal-run, and negative-result artifacts.
**Knowledge governance** adds approval-gated playbooks, markdown-backed lesson lifecycle curation, soft structural hints, and span-level credit attribution.
**Training research controls** add token-pressure diagnostics and a matched-compute OPD/GKD + GRPO mixture experiment protocol with conservative promotion gates.
**Public package polish** keeps the open-source runtime contracts, docs, and parity checks aligned for the 0.8.0 Python and TypeScript release line.
