September 2025: Stabilized the fbthrift module system by fixing an undefined template instantiation for patchByKeyImpl within Modules. Implemented explicit declarations/definitions to ensure correct instantiation and visibility, reducing build-time errors and improving module interoperability across the repository.

April 2025: Prepared Buck2 Prelude for relocatable PCM support in Clang module builds. Implemented the -fmodule-file-home-is-cwd flag pathway in cxx/compile.bzl and documented the change to enable future relocatable PCMs, aligning with upcoming Clang module handling updates. No major bugs fixed this month for this repository. Overall, the work improves build modularity and future-proofing for module compilation, reducing future refactor risk and enabling smoother adoption of Clang changes. Technologies demonstrated include Bazel Starlark scripting, C/C++ module build configurations, and version-control hygiene.

Concise monthly summary for 2025-03 focusing on fbthrift repository: delivered a critical stability fix to Protocol.h by including type_rep_types_custom_protocol.h to ensure ProtocolUnion::write is defined at the correct point of instantiation, aligning Protocol.h with Type.h and eliminating a link-time failure. This reduces downstream build errors and improves client integration.
