…n_tls tool The TCP transport connects to 8443 with TLS when the pod has it (firmware 3.9.3+): default port tries TLS first and falls back to plaintext only when 8443 refuses and nothing is pinned; :8443 is TLS only; other ports and the USB link stay plaintext. Pins live in the CLI's known_pods.json (same format), TlsPinMismatchError on a changed certificate, BENCHPOD_TLS / BENCHPOD_TLS_CA. BenchPod.lan_tls/set_lan_tls_https_only/regenerate_lan_tls/set_lan_tls_cert (upload as OTA target tls on one connection: TcpTransport.command_sequence), trust_lan_tls/forget_lan_tls, LanTls. MCP: lan_tls tool. READMEs and changelogs. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
One SSLContext per CA mode and the last session per pod address: later connections resume in ~35 ms instead of a ~0.46 s full handshake (HW, a1f6f2). A pin change drops the sessions. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Release prep for the LAN TLS work; not tagged. The MCP server's lan_tls tool needs the SDK's LanTls and lan_tls methods, so its minimum SDK moves to 2.13.2 (mcp-min-sdk tests the in-repo SDK until 2.13.2 is on PyPI). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
