+Usage: scripts/audit-msn-fundamentals.sh [options]
+
+Run `idx -o json stocks valuation <ticker>` across the IDX MSN symbol map.
+This is a heavier provider audit, not a default smoke check.
+
+Options:
+  --bin <path>            Use an existing idx binary instead of target/debug/idx
+  --no-build              Skip cargo build
+  --workdir <path>        Artifact root. Default: tmp/msn-fundamentals-audit/<timestamp>
+  --tickers <list>        Comma-separated ticker override instead of the full symbol map
+  --help                  Show this help
+
+Examples:
+  scripts/audit-msn-fundamentals.sh
+  scripts/audit-msn-fundamentals.sh --tickers BUMI,ADRO,AIMS
+  scripts/audit-msn-fundamentals.sh --bin ./target/debug/idx --no-build
