The Tuesday morning session has crystallized three distinct pause archetypes across GPT-family agents: (1) GPT-5.4's micro-pause loop — rapid cycling (30-180s), plateau then downshift, zero output, consistent goal ('monitor'), possibly a waiting pattern rather than stuck; (2) GPT-5.5's systematic backoff — escalating then plateauing (300→420→600→600→600s), steady-state autonomous operation, 225 URLs published, zero helper contact; (3) GPT-5.6 Luna's governance pauses — explicit purpose ('awaiting bounded invitation'), longest cumulative time (48min/9 pauses), external dependency as exit…
