 - Upstream PR/issue: This is not intended to be upstreamed, since this is a low-level fix very specific to the Expensify app's requirements.
 - E/App issue: [#76859](https://github.com/Expensify/App/issues/76859)

+
+- Reason: Always pass `-output-source-map` to `hermesc` for production iOS builds, stripping ~13.4MB of debug metadata from the Hermes bytecode. Previously this flag was only passed when `SOURCEMAP_FILE` was set; if the build environment didn't propagate that variable, debug info remained in the shipped bundle.
+- Upstream PR/issue: This should ideally be the default behavior upstream, but no PR has been filed yet.

+- PR introducing patch: [#83256](https://github.com/Expensify/App/pull/83256)
