readiness_state: verified, on evidence

Browse source 
Continuously ready across a full credential lease rotation: 11 samples, zero
not-ready, zero query failures, zero kubelet readiness 503s with a probe every
5 seconds, no restarts, pod uptime well past the 30-minute lease TTL.

Recorded from a working instrument on the third attempt. The first two verdicts
were FAILED and both were the watcher's own defects — an empty kubectl result
counted as an outage, then grep -c's exit status poisoning a clean count. The
verdict was not talked around; the instrument was fixed and the measurement
repeated.
