The jar's ka-vs-close throughput inversion was observed on the box but its
run configuration died with the job workspaces, so it can't be re-derived —
this commit makes the comparison a committed, controlled experiment instead
of a lost one-off.
- examples/plain_serve: the load_profile request path with zero causal
machinery (same route/handler/Config), serving until killed. The plain
half of the A/B; throughput measured externally by wrk.
- scripts/ka-close-matrix.sh: {ka,close} x {plain,causal} on fresh ports,
byte-identical wrk args per mode pair except the Connection: close
header, disjoint-core pinning for server vs wrk, per-cell curl
verification of the negotiated connection behavior, ss/env capture, and
a parsed summary with a close/ka ratio verdict. The causal cells double
as the forgiveness-fix box validation (v13 pending item, pull-forward
agreed): key on forgiven staying ~ injected x parked-actors in
close-mode churn, not process-lifetime phantoms.

//! Plain benchmark server: the `load_profile` request path with zero causal
|
|
//! machinery — the baseline half of the ka/close A/B matrix (the
|
|
//! throughput-inversion chase).
|
|
//!
|
|
//! Identical route, handler, and `Config` construction to `load_profile`;
|
|
//! differs only in having no `smarm-causal` feature, no sweep, and no
|
|
//! shutdown path — it serves until killed. Throughput is measured
|
|
//! externally (wrk).

//! URUS_PORT listen port (default 8080; binds 0.0.0.0)
