Priority: ⬇️ Low — Defer this documentation-only ADR because it defines a proposed benchmark mode without changing product behavior or showing urgent external demand. Estimated code review effort: 1 (Trivial) | ~5 minutes Change: Other Merge Risk: ⚪ Minimal · up to The change documents the proposed concurrent benchmark behavior without implementing production behavior, so it has no current user-facing runtime risk.

In `@docs/adr/0001-benchmark-mode.md`:
- Around line 37-38: Update the benchmark-mode ADR to define latency and
throughput measurement boundaries: specify timing start and end points,
treatment of concurrency-queue time, connection/TLS setup, request upload, and
complete response-body consumption. Document the percentile set and whether
failed or cancelled attempts contribute to aggregate statistics, so
implementations produce consistent WAF latency and requests-per-second values.
- Around line 36-38: Update the benchmark-mode decision around the concurrency
and aggregate-statistics sections to define the workload contract: concurrency
applies to complete FTWTest instances, stages remain sequential within each
test, and transport errors, timeouts, and expected WAF-block responses are
explicitly classified for aggregate reporting. Ensure the contract distinguishes
completed requests from failed evaluations while preserving the existing
latency, throughput, and percentile metrics.

Address review feedback: specify latency timing boundaries (connection/TLS, request send, response body, excluded queue time), the reported percentile set, and how errors/timeouts vs expected WAF blocks are classified in aggregate stats. Also clarify concurrency applies per-test, not per-stage.

what
Adds an ADR proposing a
benchmode: fire requests from existing YAML testfiles concurrently and report aggregate latency/throughput stats, without
per-request WAF log correlation.
why
Closes #143. Concurrent requests would interleave the start/end log markers
runcurrently uses for per-request correlation (runner/run.go), socorrectness checking under concurrency needs a different mechanism (a
per-transaction ID from the WAF connector) that's out of scope here. This ADR
scopes the change down to what the issue actually asked for: profiling and
latency data, not concurrent regression assertions.
