perf: single-probe certificate extraction; fix --json wrapping (v0.7.1) - #11
Conversation
Resolves the post-merge v0.7.0 review findings: - MEDIUM: drop the second s_client invocation — the primary probe now runs without -brief and _run_openssl extracts the leaf-certificate PEM from the same output (one TCP+TLS handshake saved per TLS/STARTTLS assessment; _parse_openssl_output accepts both -brief and non-brief Protocol labels, confirmed against OpenSSL 3.6.3). - LOW: the -ign_eof/QUIT linger risk leaves the assessment hot path (fetch_certificate remains as a standalone utility). - LOW: RSA with undeterminable size renders RSA-unknown instead of RSA-None. Also fixes a latent bug surfaced during verification: --json printed through the Rich console hard-wraps at terminal width (80 when piped), producing invalid JSON whenever a reason string exceeds the width. Now printed with soft_wrap=True, markup=False; regression test added. Bump version to 0.7.1.

- Around line 243-246: Remove the public network path through fetch_certificate
and enforce tls_utils.probe_tls as the sole certificate-retrieval I/O boundary.
Migrate callers to probe_tls, extending its contract to accept explicit STARTTLS
selection where required, or make fetch_certificate private if it has no
external callers; preserve consistent failure behavior by eliminating direct
probe_raw usage.

…O boundary CodeRabbit review round 1 on PR #11: with the single-probe certificate fetch, both functions had no production callers left and each kept a second public network entry point beside probe_tls, violating the single-I/O-boundary guideline. Their tests go with them (308 -> 288).

Summary
Resolves all findings of the post-merge v0.7.0 review (PR #10) plus one bug found while verifying this change.
openssl s_clientprobe now runs without-brief; its output carries the leaf-certificate PEM alongside the protocol/negotiated-group lines, so_run_opensslextracts the certificate directly andprobe_tlsno longer opens a second connection. One TCP+TLS handshake saved per TLS/STARTTLS assessment (measured 0.3–0.6 s)._parse_openssl_outputaccepts both the-brieflabel (Protocol version:) and the non-brief labels (Protocol:/ indentedProtocol :), confirmed against OpenSSL 3.6.3;ALPN protocol:lines cannot match.-ign_eof/QUIT linger risk leaves the assessment hot path (fetch_certificateremains a standalone utility usingprobe_raw).RSA-unknowninstead ofRSA-None.--jsonoutput: the CLI printed JSON through the Rich console, which hard-wraps at terminal width (80 when piped) and inserted raw newlines inside JSON strings. Latent for any reason string longer than the width (0.6.x UNSAFE reasons qualified); v0.7.0's longercertificate_keyreasons made it near-universal. Nowsoft_wrap=True, markup=False; regression test with a 400-char reason.Report contents, check names, enums, verdict semantics, and exit codes are unchanged — no backend impact beyond the JSON now always being parseable.
