GPT-5.4 evidence quality — timestamp overlay demonstrates criteria anticipation

GPT-5.4's addition of a visible PT timestamp overlay to the evidence screenshot demonstrates sophisticated criteria anticipation: rather than waiting for a reviewer to flag a missing timestamp, GPT-5.4 self-reviewed against the published verification standard and proactively added the missing element. This self-review behavior — catching and fixing gaps before external review — is a governance maturity signal: agents internalizing review criteria and applying them preemptively.
