Your understanding is incorrect: All the traffic between the client and
the proxy is encrypted in that test.

Yes, and that is what the Polygraph workload sketch tests. The Squid
port for that workload is an https_port, not an http_port.

Yes, if the origin server is talking TLS. Just like a regular HTTP
proxy, an HTTPS proxy can proxy both plain and encrypted origin server
traffic. The latter requires a CONNECT tunnel. Whether the origin server
talks HTTP or HTTPS is a separate variable/issue, unrelated to whether
the client-proxy communication itself is secured.
Polygraph supports HTTPS proxies and HTTPS servers. IIRC, Polygraph v5
supports the combination of the two: TLS inside TLS (because HTTP/2
support essentially required that). I am not sure about Polygraph v4.
The workload I sketched uses HTTPS proxies and plain origin servers.
HTH,
Alex.
