`with:` input** — Infection reads it from the environment, not a CLI flag.

`min-msi` / `min-covered-msi` (both default `"10"`) control the MSI
threshold that fails the job — config-based per repo, not hardcoded. Default
is deliberately low: most php-db repos are legacy codebases just adopting
mutation testing, and a strict bar (e.g. message-bus's 90/90) would fail
immediately. Each consuming repo overrides these once it has a real
baseline MSI to ratchet up from. Passed as `composer mutation-test --
--min-msi=... --min-covered-msi=... --logger-github` (the composer script
itself stays plain `infection`, flags are appended at invocation time, same
pattern as message-bus).
