Run a concurrency-ramp load test on an agent
Drive synthetic concurrent sessions against the agent along a staged concurrency ramp (each stage: N sessions replying a fixed script with at most K in flight) in sandbox mode, then roll the run up into a load-gate report: per-turn p50/p95/p99/max latency, cost per conversation, tool-timeout rate, optional barge-in degradation against a latency threshold, containment share, and a per-stage degradation curve. Use it to answer “will the agent survive a campaign spike?” before promoting a candidate version. Body: script.turns (≤8 utterances), ramp.stages (≤6 stages, ≤50 sessions total, ≤10 concurrent), plus optional candidate_version_id, tool_timeout_ms, and barge_in_threshold_ms. Responds 404 when the agent is unknown. Owner, admin, or developer role required.

Headers
Stripe-style idempotency token. Pass a stable, client-generated value (1-255 chars) to dedupe retries on transient timeouts. The same key+credential+path replays the original response for 24h on 2xx (5min on 4xx, 30s on 5xx). Returns 409 if a concurrent request with the same key is already in flight; replayed responses include the Idempotency-Replay: true response header.
1 - 255Sandbox opt-in for Clerk-session-authenticated requests. Set to true to route the call through the test-mode pipeline: no real provider delivery, no credits deducted, response meta.test_mode: true. Ignored for live API keys (dv_live_sk_*) — server-to-server clients must use a test-prefixed key (dv_test_sk_*) to exercise sandbox. Test-prefixed keys unconditionally enable sandbox regardless of this header.
