- Fixed memory.org source blocks to ensure persistence functions are tangled.
- Improved extract-tangle-target to handle complex Elisp expressions.
- Corrected opencortex.sh initialization paths to prevent setup loops.
- Reordered variable definitions in policy and standards skills to eliminate forward-reference warnings.
