These wall-time samples are INVALID: they were collected 2026-09-12 18:30-18:33
PDT while a competing TLS-Anvil conformance campaign (PID 3456399,
`timeout 900 /tmp/keyupdate-repro/inst.sh 6`, java at >150% CPU on a 4-core
host) was running. Retained only for transparency; excluded from all analysis.
The valid run started after the competing campaign exited.
