+- **A run's report belongs to the call that began it ([#361]).** Once a call
+  reaches the engine, its batch report belongs to that call's attempt. A call
+  the engine refuses before it begins a run (a begin outside `Ready`, a refused
+  bar array or run option, a calendar or timezone refusal, a begin over a live
+  stream) now gets the empty report (every array `NULL`, every count 0) instead
+  of the rows the handle kept from an earlier call, and
+  `strategy_native_run_v1` answers it `PF_NATIVE_E_RUN_FAILED`, never
+  `PF_NATIVE_OK`; the reason stays in `strategy_get_last_error`. The C entry's
+  `PF_NATIVE_E_HANDLE` and `PF_NATIVE_E_ARGUMENT` checks, and native-module
+  argument preflight, still return before the engine runs and leave caller
+  output untouched. A run that began and then failed still publishes its
+  partial report, and `strategy_stream_fill_report`, the explicit stream
+  snapshot, still returns a live stream's rows, even after a batch call was
+  refused over the stream. The gate is the engine's own report reader,
+  `BacktestEngine::fill_report`, so the C and native-module entry points and
+  the generated `run_backtest` / `run_backtest_full` wrappers all obey it, with
+  no change to emitted source.
