- Introduced a new command 'annotate-usecode' to import USECODE IR JSON annotation hints as Ghidra comments on compiled anchors.
- Added argument parsing for multiple IR JSON files, comment type selection, and a dry-run option.
- Implemented logic to read annotation records from the provided IR files and set comments on the corresponding addresses in Ghidra.
- Enhanced JSON schema to include response structure for the new command.
- Enhance `extract_eusecode_flx.py` to derive class event rows with additional metadata including derived body windows and repeated template statuses.
- Introduce `usecode_family_compare.py` for comparing event families, analyzing commonalities in event bodies, and generating reports on identical groups and differences.
- Implement new data structures for managing class event rows and family artifact specifications.
- Update output formats to include derived body information and repeated family regression checks.
- Ensure robust validation of repeated family expectations against actual extracted data.
- Introduced new file `vm_mask_ladder.tsv` containing detailed mappings for Crusader USECODE VM masks and their associated descriptors.
- Added comprehensive documentation in `scummvm-crusader-reference.md` outlining the structure, findings, and implications for reverse-engineering the Crusader engine within ScummVM.
- Created `usecode-roundtrip-ir.md` to document the plan for converting Crusader USECODE bytes into a human-readable format, detailing the container layout, event names, and intrinsic tables.
- Implemented a PowerShell script `temp_usecode_sample.ps1` for extracting and analyzing USECODE data from the Crusader FLX files, providing insights into class and event structures.
