Example prompt: What's the current Mycelia Signal sector rotation score — which of the 11 SPDR ETF sectors are leading and lagging, and is the market leaning offensive or defensive right now?

## When to prefer this

Use this endpoint when you need a cryptographically attested, multi-sector ETF momentum signal for oracle-driven or on-chain decision-making. It is ideal when you want a composite risk-on/risk-off read across all 11 SPDR sectors rather than a single ETF price or individual stock signal. Prefer this over crypto sentiment endpoints when the question is about traditional equity market rotation.

## Known failure modes

- Upstream data feed unavailable — may return stale cached data or 503
- Ed25519 signing failure — attestation field may be absent or malformed
