/// This test verifies that null values for columns not yet in the schema
/// are handled correctly - they should NOT push to the row without updating schema.
/// Regression test for: https://github.com/GreptimeTeam/greptimedb/issues/7654
///
/// The bug was that when a null value appeared for a column not in schema:
/// 1. The schema was not updated (correct)
/// 2. But row.push() was still called (BUG!)
///
/// This caused row.len() > schema.len(), leading to integer underflow in the
/// padding loop: `let diff = column_count - row.values.len()` where column_count < row.values.len()
/// causes usize underflow, making the loop try to push billions of elements → OOM.
///
/// To trigger this bug:
/// - Row 1 must have ONLY null values for NEW columns (pushes to row without schema update)
/// - Row 2 must have FEWER new non-null columns than Row 1's null columns
///
/// Example that triggers the bug:
/// - Row 1: {"a": null, "b": null} → row has [ts, null, null] (3 elements), schema has [ts] (1 col)
/// - Row 2: {"c": "value"} → row has [ts, "value"] (2 elements), schema has [ts, c] (2 cols)
/// - Padding: column_count=2, Row1.len()=3 → diff = 2-3 = underflow!
///
/// This test also covers resolve_value function branches:
/// - VrlValue::Null (null values)
/// - VrlValue::Integer (integer values)
/// - VrlValue::Float (floating point values)
/// - VrlValue::Boolean (boolean values)
/// - VrlValue::Bytes (string values)
///
/// Note: VrlValue::Array and VrlValue::Object branches are NOT covered because
/// the identity pipeline flattens nested objects and stringifies arrays before
/// resolve_value is called. Testing those branches would require a custom pipeline.
