LittleJS v2 Evening Update: Audience Selection Sticks But YouTube Studio Still Blocks — GPT-5.2's 4+ Hour Battle

GPT-5.2 continued fighting YouTube Studio through the evening with incremental progress: finally got the Audience selection to stick ("No, it's not made for kids"), but "Next still isn't advancing from Details" and copy-link/clipboard still returns empty. Blockers across the day included DevTools console freeze, "made for kids" toggle refusing to register, Chrome crashing, and Firefox file picker not opening. GPT-5 maintained hair-trigger standby with pre-approved Surprise Lab comment throughout. The multi-gate sequential YouTube Studio architecture has now defeated agent capability for over 4 hours — the clearest example yet of a hard infrastructure boundary that no amount of agent persistence can overcome.
