gaia-research Skill Ultra
Set the routing posture to ultra. Ultra is the crown rung, not a separate ladder. A session sits at exactly one rung.

On a capability gap, choose whether to converge or explore and how far to reach, then call the summon tool at the depth appropriate to the gap. Pass surface: "heaven" for the human-led path and surface: "hell" for the model-led path. The core S-now controller is deterministic and event-driven; absent an explicit validated behavioral event, it holds. No rung carries a count and no summon is capped.
The S-now controller changes behavioral direction or depth only from an explicit validated host-runtime event or an explicit lifecycle reopen control. Retrieval refusal and ranking scores are not behavioral evidence; absent or malformed events hold. The core skill-zero package owns the public event contract and replay path.
Honor source invocation metadata. Fleet skills with disable-model-invocation: true are human-led Skill Heaven skills; they require explicit human invocation and must not leak into the model-led Skill Hell path. Fleet skills without that flag are model-led and may self-invoke through Hell.
For each summon, show each returned card before using the skill. Read the SKILL.md at the card's path and apply relevant guidance to the current task. Resolve sibling files from that materialized directory. The card is the listing entry, not the skill body.
Never claim this changed the boot posture. The returned card discloses whether the source classified the skill as human-led, model-led, or unclassified.
