Load and shared-state evidence

The repository includes a reproducible local load harness and a generated load report.

The committed report records two different experiments:

• the same API acceptance workload against one and three FastAPI replicas;
• a direct concurrent exact-sum test of the production Redis compare-and-swap circuit-breaker storage path.

The API workload measures POST /api/run acceptance throughput and latency. In the captured run, that request path did not reach the model client, so it did not itself create the Redis circuit-breaker writes. The separate worker experiment is the evidence for Redis counter consistency.

The report is generated from committed JSON under load/results/; do not edit its measurements by hand.

To reproduce the experiment, use the instructions in the load harness README. It requires Docker and a Bash environment such as Git Bash or WSL on Windows.
