docs/README.md

+   git clone https://github.com/rzonedevops/ggnumlcash.cpp
+   cd ggnumlcash.cpp


The repository name contains a typo - 'ggnumlcash' should be 'ggnucash' to match the project branding used throughout the documentation.

Suggested change

git clone https://github.com/rzonedevops/ggnumlcash.cpp

cd ggnumlcash.cpp

git clone https://github.com/rzonedevops/ggnucash.cpp

docs/README.md

+   git clone https://github.com/rzonedevops/ggnumlcash.cpp
+   cd ggnumlcash.cpp


The directory name contains the same typo - should be 'ggnucash.cpp' to match the corrected repository name.

Suggested change

+      format: "structured_data"
+
+    right_to_rectification:
+      correction_process: "automated_where_possible"


[nitpick] The word 'correction_process' should be 'correction_procedure' or 'rectification_process' to better align with GDPR terminology and maintain consistency with other process naming conventions in the document.

Suggested change

correction_process: "automated_where_possible"

rectification_process: "automated_where_possible"

+      devices: ["cuda:0", "cuda:1", "cuda:2", "cuda:3"]
+      memory_fraction: 0.9
+      compute_mode: "exclusive"


The value 'exclusive' should be 'EXCLUSIVE_PROCESS' to match NVIDIA's actual CUDA compute mode enumeration values.

Suggested change

compute_mode: "exclusive"

compute_mode: "EXCLUSIVE_PROCESS"
