+"""Tests for read_raw_config_readonly() — the no-deepcopy raw config read.
+
+The readonly variant exists for per-turn policy checks (e.g. the
+shared-metrics gate) that were paying a full config deepcopy on every call.
+Contract under test:
+
+1. identity invariant — repeat calls return the SAME cached object,
+   including across the very first (cache-miss) call;
+2. freshness — an edited config.yaml (mtime/size change) is picked up;
+3. parity — content equals read_raw_config()'s result;
+4. missing/broken config degrades to {} exactly like read_raw_config().
