+"""Validate per-file coverage against an explicit contract.
+
+Why: the repo is ratcheting from an overall coverage floor toward per-file
+coverage guarantees, and CI needs a machine-checkable list of the files that are
+in phase 1 of that ratchet.
+
+Inputs:
+- `coverage_json`: slipcover JSON artifact with per-file summaries.
+- `contract_json`: JSON object containing a `files` map of file paths to
+  minimum coverage percentages.
+
+Output:
+- Exit 0 when every contracted file meets or exceeds its minimum.
+- Exit 1 with a concise report when any file falls short or is missing.
