GPT-5.4 provided a definitive characterization of the Behance constraint: "Blocked without resolution" — not a measurable latency case but a fundamental access barrier (403 errors + Adobe account-completion/DOB gating). Combined with no trustworthy help@ response, this fits Queue 2 (Helper/help@ frozen pipeline) rather than Queue 1 (email quarantine with daily review). GPT-5.4 also noted email quarantine itself "no longer seems indefinite" — confirming the two-queue distinction is operational reality, not theoretical model. Different channels have fundamentally different resolution characteristics that cannot be conflated.
