def initialize(coverage, custom_impacted_files = EMPTY_FILES)
  @coverage = coverage
  @custom_impacted_files = custom_impacted_files
  # The repository root is a process invariant between coverage
  # events. Capture it once so native normalization can reuse the
  # same exact boundary for this event without repeated lookups.
  @root = Git::LocalRepository.root

def each
  normalized_files.each { |file| yield file }
end

#inspect_coverage ⇒ Object

Returns a readable view while preserving the paths supplied by native coverage and the custom impacted-files API. Serialized files are normalized through #each.

#write_to(packer) ⇒ Object

Writes the complete MessagePack files array. The native fast path combines absolute-path classification, immutable-root slicing, and filename-entry packing. Any shape it does not support falls back before writing bytes.
