[POC] === RESULT ===
[POC] wall-clock hidden interval         : 5.113 s
[POC] totalDuration delta (incl. hidden) : 6.782 s
[POC] underrunEvents delta               : 0
[POC] underrunDuration delta             : 0.000000 s
[POC] latency over interval [min/avg/max]: 0.030000 / 0.031330 / 0.032879 s
[POC] expected delta if hidden data were DISCARDED : ~1.5 s (settle window only)
[POC] expected delta if hidden data were RELEASED  : ~6.6 s
[POC] VERDICT: VULNERABLE -- hidden-period playout stats (~5.1s worth) were released wholesale on first visible Absorb(). Visibility gate provides no suppression.
[+] DONE — verdict: VULNERABLE
