Read src/frontends/gguf/docs/how_to_add_op.md — the five-file checklist (including the test CMake source list, which is not globbed), the NodeContext API, the mandatory op-coverage gate, where reference values must come from, and the build/test commands (-DENABLE_OV_GGUF_FRONTEND=ON).
Confirm a translator is really what is missing: a new architecture usually needs only a name in arch_registry.cpp, and a structurally different use of an existing op is an op_case. Both are covered in that document.
Find the closest existing op with grep -n "GGML_" src/frontends/gguf/src/op_table.cpp and the closest test with grep -n "^TEST(" src/frontends/gguf/tests/test_ops.cpp, then read only those ranges — do not read test_ops.cpp in full.
Implement, then build and run ov_gguf_frontend_tests — filtered while iterating, unfiltered before finishing so the coverage gate runs.
