Steps

Step 0: Run perf_scan.py

python team/spine/scripts/spine_agent/perf_scan.py [target] [--base-url http://...] [--paths /api/orders /api/users] [--skip-n1] [--skip-endpoints]

Run the real-tool layer first. This executes:

• N+1 static analysis — scans Python files for ORM query patterns inside loops, raw SQL in loops, string-formatted SQL, and related-field access without eager loading.
• Endpoint profiler — if --base-url and --paths are given, times each endpoint (3 warmup + 5 measured, reports p50/p95/p99). Flags endpoints >200ms (MEDIUM), >500ms (HIGH), >1000ms (CRITICAL).
