Third Python implementation in the latency-tool progression. Mirrors latprobe's feature set but replaces raw sockets with httpx, gaining HTTP/2 support and redirect following. Package layout (hxprobe/hxprobe/): - probe.py: asyncio + httpx.AsyncClient with a _TimingStream transport wrapper that captures DNS/connect/TLS/TTFB/transfer phase timings via httpx event hooks (get_connection_stats, request_started, etc.). VerboseDetail captures resolved IP, TLS version/cipher/bits, cert CN/ expiry/issuer (from httpx's SSLObject), and response headers. Options: timeout, verbose, follow_redirects, http2 - aggregate.py: summarize() → per-phase min/avg/max (same schema as latprobe) - cli.py: run(args,stdout,stderr)->int; argparse with redirect_stdout/ redirect_stderr + SystemExit catch; -n/--count, -c/--concurrency, --timeout, --fail, --json, -v/--verbose, --no-follow-redirects, --no-http2, -f/--file (URL list from file, mutually exclusive with args); multi-URL summary footer (tally + exit label) when len(urls) > 1; worst-exit-code logic mirrors Go/latprobe; JSON output is bare array - duration.py: same parse_duration() as latprobe - Exit codes: 0 ok, 1 usage, 2 dns, 3 connect, 4 timeout, 5 tls, 6 http≥400 Tests (hxprobe/tests/): - test_probe.py: 18 hermetic tests using anyio + in-process ASGI servers - test_cli.py: 36 hermetic tests (success, failures, JSON, verbose, -f flag, run-summary footer, worst-code accumulation) - test_integration.py: pytest-marked @integration (excluded from hx-test) Toolchain: uv + ruff + pytest; pyproject.toml with [dependency-groups]; hxprobe/Makefile standalone (help, deps, run, lint, fmt, test, test-integration, check, clean); .python-version pins 3.14 Configs: 8 fixture files mirroring python/configs/ (all-ok through mixed) USAGE.md: 16 runnable examples with real captured output Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# Connection-refused errors — loopback addresses with no server on those ports.

# The OS rejects the TCP SYN immediately, so these fail in milliseconds.

# Run: uv run python -m hxprobe -f configs/connection-refused.txt
