# Plus Ultra
Go beyond: two independent minds propose, one arbiter rules, reality confirms.
## The loop
```text
task -> proposer A (read-only, blind) --\
-> arbiter -> one plan -> main applies once
task -> proposer B (read-only, blind) --/ |
v
fresh reality verifier (plan-blind)
```
1. Check the host's agent budget. If it cannot support the full loop, say so before degrading.
2. Spawn two isolated, read-only proposers with the same task specification.
- A must not assume any command succeeded; it reads actual state.
- B must name an alternative approach it rejected and why.
3. Give both proposals to one arbiter. It returns a single authoritative plan or escalates a
fundamental disagreement to the human.
4. The main thread applies that plan once. Proposers never mutate live state.
5. Spawn a fresh verifier that has not seen the plan. State only what should now be true and have
it inspect the world independently.
Each proposal includes exact changes, verification, rollback, and uncertainties. The arbiter must
not average incompatible plans into vague consensus.
## Decision matrix
| Agreement | Arbiter action |
|---|---|
| Full | Apply; confidence 90+ |
| Minor differences | Pick the cleaner plan; confidence 80+ |
| Structural differences | Analyze and merge explicitly; confidence 60-85
