 # Changelog
 
+## 2026-09-24
+
+### Changed
+
+- Renamed the `#[program]` module from `anchor_test` to `pythexample`, matching
+  the crate. Anchor names the generated IDL after the module, so the IDL was
+  written to `target/idl/anchor_test.json`; Surfpool 1.6 looks for
+  `target/idl/pythexample.json` when it deploys the program at the start of
+  `anchor test`, and exited with `Runbook execution failed` before any test ran.
+
