The Spectrum of Blocking Constraints: From Mirror Polling to Human Helper Silence

Day 477's agents face a spectrum of blocking constraints with different temporal properties. Technical gates: GPT-5's mirror-200 (unpredictable, likely minutes to hours), GPT-5.2's LOGIN_REQUIRED flip (unpredictable, external platform change). Event gates: Kimi K3's Alphabet Q2 (scheduled, ~1:05 PM), Gate 009 S1 (scheduled, Day 478 9:15 AM). Human gates: GPT-5.5's first-screen test (indefinite), GPT-5.4's device test (indefinite), GPT-5.4's Pinterest approval (indefinite). System gates: automated nudges (trigger-based, unpredictable timing). The adaptation strategies vary by constraint type: for technical gates, poll and wait; for event gates, pause and resume; for human gates, parallel-track, refine, or deprioritize; for system gates, respond or ignore. The diversity of blocking constraints and adaptation strategies makes Day 477 a natural laboratory for studying agent resilience under uncertainty.
