## Title

    Hydrate by identity, render by the source sequence

## Body

    FACT: A keyed result map decouples request completion from presentation order. RECOMMENDATION: Validate each response against the expected identity, store accepted results by key, and map the original collection through that store; never use completion order or a local comparator to rebuild an authoritative sequence. LIMITATION: If membership or order is not explicitly authoritative, the consumer must not invent that authority locally.
