Server	Role	Instance
Endee Server	Endee VectorDB — code from this branch	t2.large
Benchmark Server	Benchmark runner	t3a.large

Both servers start on demand and are always terminated after the run — pass or fail.

How Correctness Benchmarking Works

1. Post /correctness_benchmarking <mode>
2. Endee Server Create  →  this branch's code deployed  →  Endee starts in chosen mode
3. Benchmark Server Create  →  benchmark suite transferred
4. Benchmark Server runs correctness benchmarking against Endee Server
5. Results posted back here  →  pass/fail + full metrics table
6. Both servers terminated   →  always, even on failure

After a new push, CI must pass again before this menu reappears.
