/readyz walked the hash chain and opened pooled connections with no
libpq connect_timeout, so a 2s kubelet probe never saw a response and
the pod stayed unready. Informed Decision accept is blocked on that.
Probe health() only, under a 1.5s budget, publish last-known
tamper_evidence, and fail TCP handshake in 1s. Integrity stays on
/v1/integrity.
