# Strategy Lifecycle
> Submit, simulate, evaluate, score, produce evidence, and progress toward eligibility.
The Strategy Arena lifecycle is intentionally staged. Each stage has a different
owner and a different evidence requirement.
## Lifecycle
The builder creates a candidate strategy for a supported market family.
The system resolves official market data and execution policy, then emits
reproducibility metadata.
Ranking evaluation computes utility, benchmark-adjusted score, CapitalScore,
diagnostics, and eligibility output.
The beta score is displayed publicly; CapitalScore remains a stricter
robustness diagnostic.
Replayable artifacts explain why the candidate ranked where it did.
Eligibility means the strategy passed configured gates. It is not a capital
commitment.
Future deployment decisions remain constrained by vault rules and review.
## 1. Submit
The builder creates a candidate strategy for a supported market family.
In public beta, the candidate is sent through the Strategy Arena API. In the
encrypted intent path, protected inputs are submitted through an on-chain intent
record and processed by the private operator runtime.
## 2. Simulate
`simulation-service` resolves the official market dataset and execution profile,
runs strategy components through `spot-strategies`, applies execution adjustment
through `amm-math`, validates invariants, and emits reproducibility metadata.
The public competition profile uses server-controlled datasets, costs, and
scoring windows so candidates are comparable.
## 3. Evaluate
`ranking-evaluation` computes scenario utility, benchmark-adjusted score,
CapitalScore diagnostics, and eligibility output. Evaluation failures are typed
and explicit.
## 4. Score
The beta score is the public display score returned by the evaluation endpoint:
$$
\mathrm{score} = 100 \times \frac{\mathrm{strategyUtility}}{\max(\mathrm{benchmarkUtility}, 0.0001)}
$$
CapitalScore is a stricter diagnostic for robustness across scenarios. It is
not the same as contest scoring.
## 5. Evidence
Evidence is the set of replayable outputs that let another reader understand
why a candidate ranked where it did:
* simulation output hash,
* benchmark utility,
* utility breakdown,
* eligibility reason codes,
* report hash,
* dataset and registry metadata.
## 6. Eligibility
Eligibility means a strategy passed configured gates. It is not a capital
commitment.
Evidence creates eligibility. It does not guarantee capital.
## 7. Guarded path
Future guarded deployment should follow vault constraints for assets, size,
execution permissions, and operational risk. The arena evidence is the input to
that decision, not a bypass around it.
