- Added a comprehensive error propagation standardization report detailing dominant patterns, inconsistencies, and recommended remediations (`docs/audits/error-propagation-standardization.md`). - Integrated `ErrorHandler` into key components, including `main.cc` for robust exception reporting, and added centralized logging to a user state path. - Introduced EINTR-safe syscall wrappers (`SyscallWrappers.h`, `.cc`) to improve resilience of file and metadata operations. - Enhanced `DEVELOPER_GUIDE.md` with an error handling conventions section, covering pattern guidelines and best practices. - Identified gaps in `PieceTable` and internal helpers; deferred fixes with detailed recommendations for improved memory allocation error reporting.
