The failing test-wasm job on Node 22 was caused by a JS/Rust binding mismatch: JS tests call camelCase methods (toJson, toCsv, toCamt053) that were not exported under those names in the WASM bindings for the failing revision.

• Root cause addressed

  • Align WASM-exported method names with JS integration test/API expectations.
  • Ensure Node-target test builds use the dev profile path used by CI test execution.

• WASM binding API alignment

  • Added explicit wasm_bindgen JS name mappings for export methods in crates/wasm/src/lib.rs:
    • to_json → toJson
    • to_csv → toCsv
    • to_camt053 → toCamt053

• WASM package script adjustment

  • Updated crates/wasm/package.json build scripts so npm test uses the Node build mode that preserves expected JS-export behavior in CI.
