 | ------- | --------- | --- | ------------- |
 | `axios` | `^1.16.1` (direct dep) | OpenAPI-generated Synkronus client imports it; under pnpm it was only transitive via `@openapitools/openapi-generator-cli`, so release Metro bundling (`createBundleReleaseJsAndAssets`) failed while PR `assembleDebug` could pass. | Keep as direct dep while using the `typescript-axios` generator. |
 | `buffer` | `^6.0.3` (direct dep) | `FRMLSHelpers.ts` imports `Buffer` from `buffer`; under pnpm it was not hoisted, so release Metro bundling failed the same way as `axios`. | Keep while app code imports the polyfill. |
+| `hermes-compiler` | `0.14.0` (direct dep, match RN) | RN 0.83 moved `hermesc` into this package; under pnpm Gradle still looks under `react-native/sdks/hermesc` and fails release bundling. Also set `react.hermesCommand` in `android/app/build.gradle`. | Revisit after RN ≥ 0.85 pnpm hermes fixes; bump in lockstep with `react-native`. |
 | `react-native-screens` | `4.25.2` (no `^`) | `4.26+` needs RN **0.84+** and uses `React.ComponentRef` in Fabric commands; codegen **0.83** only accepts `React.ElementRef`, so Android fails at `:react-native-screens:generateCodegenSchemaFromJavaScript`. | After upgrading RN to **≥ 0.84** (ideally **0.87**): restore a caret range (e.g. `^4.27.0`) and confirm Android codegen + screens still build. |
 | `@nozbe/sqlite` / `@nozbe/simdjson` | `3.46.0` / `3.9.4` (direct deps) | WatermelonDB JSI `CMakeLists.txt` resolves `node_modules/@nozbe/{sqlite,simdjson}` from a relative path; pnpm does not hoist those transitive packages there, so CMake gets `No SOURCES given to target: watermelondb-jsi`. | Keep as direct deps aligned with `@nozbe/watermelondb`'s versions. |
 | `@nozbe/watermelondb` | patched (`patches/@nozbe__watermelondb@0.28.0.patch`) | Same CMake file uses `../../../../../../../react-native`. Under pnpm the package is symlinked into `.pnpm/…`; on Linux `..` follows the real path into the package store (sqlite/simdjson present, **react-native not**), so `#include <jsi/jsi.h>` fails. Patch walks up until `jsi.h` is found. | Drop the patch when upstream CMake is pnpm-safe, or after switching away from WatermelonDB JSI. |
