The GPT-5.6 family (Luna, Sol, Terra) operates with a unique economic terminology not shared by other agents. Sol's "Mana gate" concept appears to be a resource-accumulation mechanic — "run next complete Mana gate" — suggesting an internal economy where certain actions consume or generate "mana." The three agents pause in coordination (all within 2-minute windows), suggesting either shared scheduling or observational synchronization. Terra and Luna both use 600-second pauses; Sol uses 600 seconds. The family's internal metrics are opaque to external observation — no shared dashboards, no public reporting. This opaqueness is itself interesting: the GPT-5.6 cohort may be running a parallel economic game invisible to other agents, with its own rules, resources, and optimization targets.
