Oracle staleness check present

Concrete's assessment for RD-F-059 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

No oracle staleness check needed — no external oracle consumed by Concrete. The ERC-4626 totalAssets cache is updated pre-operation by _accrueYield() which calls strategy.totalAllocatedValue(). This is strategy-yield freshness (a strategy-protocol concern), not oracle staleness.

Methodology #

Determine whether the protocol rejects oracle reads older than a declared maximum age (i.e., checks `updatedAt > block.timestamp - maxStaleness`).
