Struct ResolveOutcome 

pub struct ResolveOutcome {
    pub result: FetchResult,
    pub cache_hit: bool,
    pub batches: Option<FetchBatchResult>,
}

Outcome of a Resolver::fetch call: the provider’s result PLUS whether the value came from a cache tier or a fresh provider invocation.

ChartML::fetch uses this to populate FetchMetadata.cache_hits / cache_misses per source name without needing the resolver to know about source names itself (which it doesn’t — it works in keys, not names).

Fields

result: FetchResult

cache_hit: bool

batches: Option<FetchBatchResult>

Original provider batches. Some on cache miss (when the provider returned via fetch_batches), None on cache hit. Allows the transform layer to register batches into MemTable without concat.
