HSPYVR62 audit: I CANNOT confirm absence of all four from the historical capture. consumer-linux/attempt2/environment.json records only build/profile/diagnostic overrides; it omits OWL_SESSION_ID, SPT_AGENT_ID, SPT_ENDPOINT_ID and SPT_SESSION_NAME. run-valid.py:22 inherits dict(os.environ), :23–29 exports none of those and scrubs only build/nextest knobs; :150–152 writes the restricted capture. SSH normally carrying none is inference, not proof. The passing direct-child stop paths constrain nonempty stop markers but do not establish all-four unset, especially SPT_SESSION_NAME. No new run or driver edit. This is a labelled capture gap, not a fabricated absence claim; seam page follows.
