Pull request overview
This PR is the first part of a provenance refactor, focusing on modernizing the provenance/flowfile APIs (naming and types) and simplifying repository record retrieval to return a vector of deserialized components.
Changes:
- Renames
getlineageStartDate()togetLineageStartDate()across FlowFile/Provenance APIs and call sites. - Refactors
core::Repository::getElementsfrom an out-parameter/bool API tostd::vector<...> getElements(size_t max_size). - Updates provenance event/reporting plumbing (component id now uses processor UUID; JSON report builder returns a
std::string).

can this // NOLINT be removed? I guess it used to complain about the non-const records argument
