Defined in:

Overview

Reads a Stryker-compatible mutation report and extracts survivor data.

Returns a Report value object carrying:

- +survivor_ids+  — stable IDs of survived mutants
- +coverage_map+  — stableId → [test_files] from prior coveredBy data
- +git_sha+       — git HEAD at the time the report was written (may be nil)

Scope validation is intentionally shallow: checks schemaVersion presence and at least one file path overlap with config.includes.
