crates/gunnar-loadbench/Cargo.toml
# gunnar's **estate load bench** — a detached crate with its own `[workspace]`,
# exactly like `installtest/` and `crates/gunnar-growbench/`, so gunnar's own
# `Cargo.lock` never learns about a harness.
#
# ## What it measures
#
# How the THREE-VM gunnar.rs estate behaves under a declared concurrency and a
# declared request rate:
#
# * the front's public pages (`/health`, `/login`), served by Caddy + the
# console's axum BFF on 95.111.204.164;
# * the console BFF's UNAUTHENTICATED read endpoints (`/auth/status`, and
# `/login/repos`, which is the only public route that goes all the way
# through to gunnar's gRPC control plane and back);
# * gunnar's git SSH front door on `:2222` — an SSH transport handshake
# (banner + KEXINIT algorithm negotiation) against the real
# `SSH-2.0-gunnar_*` listener, and, with `--features git-ssh`, a real
# protocol-v2 `ls-refs` through `gunnar_client::ls_remote` (russh, pure
# Rust, no `git` subprocess).
#
# For every probe it collects p50/p90/p99/max latency, achieved throughput, and
# refusals COUNTED BY REASON. A refusal is a measurement, never a panic: a 503
# `{"code":"maintenance"}`, a 401, a read timeout and a connection reset are
# four different facts and are counted in four different buckets.
#
# ## Why a detached crate and not a workspace member
#
# The same two reasons `installtest/Cargo.toml` records:
#
# 1. a workspace member takes part in resolver-2 feature unification, so a
# dependency here could switch a feature on inside the appliance build;
# 2. a member's dev-dependencies are built by `cargo test --workspace`, which
# would drag a load generator into gunnar's ordinary test run.
#
# ## The engine
#
# `gatling` (published as `rotaryengine`) — the constellation's ONE shared
# no-barrier worker-pool engine. `gatling_for_each(n, workers, f)` is exactly
# the shape a closed-loop load generator wants: all `n` requests are known up
# front, ONE output slot per request is pre-allocated before a single packet
# moves, and `workers` threads drain a shared atomic cursor with no lock and no
# barrier. rayon is forbidden by the law and is not here.

# which is minutes and gigabytes. Without it the SSH probe is still real: it
# speaks RFC 4253 §4.2/§7.1 down to KEXINIT with nothing but `std::net`.
