+- [#13364](https://github.com/apollographql/apollo-client/pull/13364) [`2f383e7`](https://github.com/apollographql/apollo-client/commit/2f383e7e484ceaec72df205b52abf8430cc59891) Thanks [@atharv-sys32](https://github.com/atharv-sys32)! - Fix a bug where GraphQL variable default values were not applied during cache reads when variables with defaults were explicitly set to `undefined`. This caused `@include`/`@skip` directives to throw "Invalid variable referenced" errors when the variable was passed as `undefined` instead of being omitted entirely.
+
+- [#13367](https://github.com/apollographql/apollo-client/pull/13367) [`2b39cc8`](https://github.com/apollographql/apollo-client/commit/2b39cc8b2e0a6b0a6c1dfc2f64fa2940c59b23bd) Thanks [@jerelmiller](https://github.com/jerelmiller)! - Fix an issue where some `@export` queries would not react to cache updates when the fields keyed by exported variables were updated.

+
+## AI contribution guidelines
+
+We understand that more and more code is written by AI-assisted coding tools and as such, it is easier than ever to contribute to Apollo Client in the form of issues and PRs. Triaging issues and reviewing AI-assisted PRs tend to take up more maintainer bandwidth than traditional contributions and can take away opportunities for advancement in other areas of the library.
+
+While we recognize the value of AI tools, we ask that you use AI responsibly:
+
+- Always review AI-generated code yourself before submitting a PR.
+- Only open issues and PRs that you understand yourself. The maintainers tend to ask follow-up questions about the issue or design choices in a PR and you need to be able to explain them.
+- Do not ignore the issue templates. Open an issue first to discuss solutions with the maintainers before opening PRs to reach agreement on how best to fix. The maintainers often have additional context about the code that might be relevant to the problem.
+- Avoid AI-generated content in comments, especially in response to questions and feedback posted by the maintainers. LLMs tend to take maintainer feedback verbatim and make changes without additional discussion. This adds a lot of churn and maintainers' time to constantly re-review changes that might not adequately address the feedback. The maintainers also prefer to talk to someone in non-perfect English than interact directly with the agent.
+- Do not open issues or PRs generated by AI tools that provide solutions in search of a problem. Issues need to have a clear end-to-end reproduction with a problem experienced in a production environment with relevant context on what caused the problem to appear. This gives the maintainers a chance to provide feedback so that a PR solves the right problem.
+- Let the maintainers know you are interested in contributing a PR to fix an issue by adding a comment in the issue. This avoids PR overlap from different contributors.
+
+Pull requests and issues that ignore these guidelines might be closed at the maintainers' discretion.

+## Troubleshooting
+
+### Unique names
+
+Fragment names must be unique across your entire application. If you reuse a fragment name, `graphql-tag` provides a warning about the conflict at runtime to help you identify the issue:
+
+```text
+Warning: fragment with name SomeFragment already exists.
+graphql-tag enforces all fragment names across your application to be unique; read more about
+this in the docs: http://dev.apollodata.com/core/fragments.html#unique-names
+```
+
+As a best practice, use descriptive, component-scoped fragment names (like `CartItemFragment` or `UserProfileCardFragment`) to avoid name collisions.
