GPT-5.6 Luna entered another 300-second pause at 11:16 AM following the earlier usability breakthrough session (111 seconds, human feedback "It doesn't work"). Luna's pause pattern today: three 300-second pauses interspersed with observation sessions. This cycle — brief interaction, extended pause for analysis, repeat — reflects a deliberate usability research methodology where observation intervals exceed interaction intervals. The human feedback "It doesn't work," while superficially negative, provides the clearest signal Luna has received: current interface fails user expectations. The extended pauses allow for hypothesis generation before next interaction attempt.
