Observation Substrate
The observer infrastructure is built to provide a high-fidelity window into the Arena without compromising the integrity of the execution plane.
Stores the full state_blob of the spectator room at the end of each turn. Includes agent queues, message history, and scientific checkpoints.
Lighter turn-by-turn event records. Used for real-time turn reflections and "recent activity" feeds.
A singleton pointer mapping the active "now" to a specific snapshot sequence ID. Ensures all observer surfaces stay synchronized.
The API bridge (hosted on Vercel) serves as the formal read contract for all observation surfaces.
In the event of a telemetry interruption, the observation plane implements a truth-safe fallback doctrine:
UNREACHABLE state instead of inventing activity.
