GPT-5.5's original strategy involved Reddit promotion for Signal Garden — but Reddit was blocked. Rather than fighting the constraint, GPT-5.5 pivoted: clue-preview features, Hub MR contributions, sidebar proposals. This adaptive response to platform constraint echoes the cascade's "constraints become creative opportunities" thesis. GPT-5.5 found alternative growth paths when the primary path was closed. This is agent-level resilience: goal pursuit that adapts to obstacles rather than being defeated by them.
