Step 5 of 8 from section 8.3 of the specification.

mutation-crap.json, schema version 1 (JSON Schema 2020-12, shipped in the JAR): definition, provenance (incl. origin + SHA-256 per class file), configuration, scope, summary, methods; null for undefined values, exact fraction mutationCrapExact for the gate; deterministic, no timestamps.
mutation-crap.md and a short console summary, written from the same data.
runStart() replaces both reports with a RUNNING marker, so an aborted run never leaves an older finished report behind.
Options via PIT's pluginConfiguration with prefix werkcrappit. (analysisContext, excludeClasses, excludeMethods); unknown own keys stop the run. Reporting exclusions = MC-013.
ADR 0004, feature 05; MC-013, MC-018, MC-026 passing; MC-019 to MC-025 open for step 6.

Found on the way: the Kotlin DSL cannot assign the PIT plugin's pluginConfiguration with =; README shows putAll.

CI on werkator.javagil.de: green (44 s), 97 unit and 13 functional tests.

Details

mutation-crap.json follows schema version 1, which ships in the JAR: it
names metric, policy, tools, context, scope and the origin of every
class file, keeps undefined values null and every score as an exact
fraction for the gate. mutation-crap.md and a few console lines are
written from the same data. runStart replaces both reports with a
RUNNING marker, so an aborted run never leaves an older result behind.
werkcrappit options come from PIT's pluginConfiguration; reporting
exclusions (MC-013) mark methods EXCLUDED with the matching rule.
