- Created `crusader_segment_coverage_ledger.csv` to track segment coverage status, types, and known functions. - Introduced `plan-mid.md` as a mid-project tracker outlining progress, objectives, and implementation priorities for the decompilation effort. - Added scripts in `pyghidra_plans` to assist with instruction window dumping and reference inspection for the object at `0x4588`. - Implemented functionality to scan for instruction uses of specific targets related to the decompilation project.
