Extend dosh-bench to benchmark the full attach path matrix and emit both raw
per-iteration samples and summary statistics (count/min/median/p95/mean/max):
- --cold-native: native cold auth terminal-ready (dosh_cold_native_ms)
- --cached-ticket: cached attach-ticket fast path (dosh_cached_attach_ms)
- --resume: UDP resume path (dosh_resume_ms; roaming-only, see docs)
- --local-auth: self-contained local bootstrap, no SSH (dosh_local_attach_ms)
- default: legacy SSH-bootstrap cold attach (dosh_attach_ms)
Existing ssh-bootstrap/local-auth/mosh modes and all assert gates are preserved;
legacy flags (--local-auth/--warm-cache/--no-cache) keep their prior behavior so
the CI docker scripts run unchanged. Add --json (machine-readable raw samples)
and --label. Add a table/JSON renderer and percentile-based summary stats.
Add scripts/bench-local.sh: a safe, self-contained harness that builds release,
spins up a throwaway dosh-server bound to 127.0.0.1 on a random free UDP port in
a temp HOME (never port 50000, never a systemd unit), runs the matrix, prints
results, sanity-checks native auth actually trusted the host, and cleans up.
Point `make bench-local` at the new harness and add `make bench-local-json`;
keep bench-docker-* targets intact.
Add docs/BENCHMARKS.md: how to run each benchmark, metric meanings, methodology
and caveats (resume is the roaming path, not cold reconnect; cite cached attach
as the core claim per PUBLIC_READINESS.md), plus a real loopback sample table
with machine/OS/sample-count and raw samples.
