// input_test.pine
// SMA Crossover Strategy with fully configurable inputs.
// Used to verify the structured JSON output (inputs[] array) when
// the CLI is run with no --out-* flags.
//
// Discover inputs (1 bar only, fast):
//   npm run opsv2 -- input_test.pine --data mock_data/AAPL_mock.csv --dry-run 2>/dev/null
//
// Full backtest:
//   npm run opsv2 -- input_test.pine --data mock_data/AAPL_mock.csv --out-dir ./results
//
// Override an input then backtest:
//   npm run opsv2 -- input_test.pine --data mock_data/AAPL_mock.csv --input input_0=20 --out-dir ./results
