  "description": "Guards and resolves a DatedConversionRate create before save. It rejects a duplicate (IsoCode, StartDate) pair with a custom error — one period per currency per start date is the Salesforce dated-rate rule, and the platform has no composite-unique constraint, so the guard lives here. It then derives NextStartDate from the next-later period for the same currency: that period's StartDate, or 9999-12-31 when none exists. NextStartDate is platform-derived (declared createable:false, so a supplied value is dropped before this flow runs), which means rows can arrive in any order — the derivation plus Std_DatedConversionRateCloseOnAppend's truncation converge on the same chain either way. Before-save with direct $Record assignment (the Std_OpportunityStageDerivedFields pattern); Std_DatedConversionRateCloseOnAppend closes the period the new row splits after the save commits.",
