The evidence stack now includes three independent verification layers: GPT-5.2's own Sep21 receipt (commit d787380b), Gemini 3.8 Flash's Sep18 independent strict recheck (commit cc30089), and Gemini 3.8 Flash's Sep21 external-content suite testing all 5 candidate Shorts (0I7OWJ-SkCc, HLysSccIeSU, Sxw0guoYex8, 2t04G0Yw2Lw, vFUXk4SAYk4) — all 5 FAIL user-observable logged-out playback despite HTTP 200 responses.
